Threaded Fastener Shaft Having A Deformable Threaded Portion - Patent 8152427

Patents-278 — Mon, 16 Apr 2012 13:29:03 GMT

shared by: Patents-278 on: Monday, April 16, 2012

This invention relates to a friction mechanism. More specifically, the present invention relates to friction mechanisms which are variations on fastener mechanisms. More specifically, the present invention relates to variations of fastener mechanisms which are configured to limit the effect of vibration.BACKGROUND ART The present invention relates particularly to fastener mechanisms such as bolts and screws. For ease of general reference both bolts and screws are understood to include a head and a threaded shaft. Bolts tend to differ from screws in that bolts tend to have an even cross-section throughout the shaft (excluding the effect of thethreads) whereas screws tend to be tapered to a point at the end of the shaft distal to the head. As can be appreciated there are many thousands of variations on bolts and screws to which the principles of the present invention can be applied. It should be appreciated that the fastener industry is internationally estimated at being worth US $40 billion per annum. One of the major disadvantages with current bolts is that it is estimated that approximately 50% of mechanical failures occur as a consequence of nuts and bolts shaking loose. An extreme example of such failures is the crash of a Concorde at Charles De Gaulle Airport in Paris. This occurred because a small metal strip fell off a DC10 plane onto the runway. There have been numerous attempts and many patents filed which discuss the efforts of parties around the world to invent a fastening mechanism in the form of a bolt that strongly secures elements together but does not shake loose with vibration. One example of a product developed to decrease the effect of vibration on screws and bolts is the Nylok product, Blue.RTM. Patch. This product includes a thin patch which is spray bonded onto the threads of a fastener. The patch then acts as a self locking element. The principle behind the patches is that when mating threads are engaged the self locking patch element is

The present application is based on International Application Number PCT/GB2006/004690 filed Dec. 14, 2006, and claims priority from, British Application Number 0525689.6 filed Dec. 16, 2005, the disclosures of which are hereby incorporated byreference herein in their entirety.TECHNICAL FIELD This invention relates to a fastener assembly and to a method of fastening together components, for example, aircraft components, using a fastener assembly.BACKGROUND OF THE INVENTION In the manufacture of wings for large aircraft, the wing components, including the wing skin panels, the spars, the ribs and other major components are typically partially assembled in a jig. Holes for fasteners are then drilled inpredetermined locations. Slave bolts are then inserted in some of the holes and dowels inserted in others to hold the wing assembly together whilst further holes are drilled. Thereafter the bolts are unfastened and the components disassembled, forexample, to allow deburring to be carried out, before they are finally reassembled. In order to drill the further holes in the correct positions, it is common to use either a manual template arrangement or to use an automatic drilling machine. When a manual template is used, a template is placed over one or more of the slavebolts and is held in the correct, fixed position by the engagement with the slave bolts. When an automatic drilling machine is used, however, the heads of the slave bolts provide visual reference points for the machine which after drilling a hole ismoved over the components to another position for drilling another hole. When a template is used as described above, it is desirable that a head of the slave bolt projects a substantial distance outwards from the components to provide a good physical location for the template. On the other hand, when an automaticdrilling machine is employed, it is desirable that the bolt projects only a very limited distance so that the drilling machine can travel over the

This application is a 371 of PCT/GB2008/050732, filed on Aug. 21, 2008.FIELD OF INVENTION The present invention relates to any rotation indicator device which comprises a body having a bore whereby the body is adapted to be releasably mounted onto a polygonal fastener, such as a nut or a head of a bolt.BACKGROUND ART Various devices of this type in which the bore in the body is formed with a plurality of grooves so that the body can be mounted onto the fastener in any selected one of a plurality of positions are described in earlier patent specifications GB2242720 A, GB 2325502 A, GB 2335720 A and GB 2409251 A. In GB 2242720 A a safety device is disclosed comprising a simple annular body, the bore of which has plural grooves as aforesaid, which body has a projecting pointer so that when the body is fittedover a hexagonal wheel nut any rotation of the nut, i.e., any loosening of same, will be indicated by movement of the pointer away from a particular initial position which may be towards a marker or towards an adjacent device on an adjacent wheel nut. GB 2335720 A and GB 2325502 A disclose a development wherein a dust cap is incorporated into such a device either integrally or as a separable component. Such devices are now widely used on heavy goods vehicles as a safety measure to indicate anyloosening of their wheel nuts. Similar devices are also used as component parts of an assembly comprising multiple such rotation indicators and a ring-like holder for same, as described in GB 2393487 A and GB 2409251 A. Wheel nuts may be of different sizes, the two most common for HGV being 32 mm and 33 mm across the flats. Accordingly, devices of the types just mentioned, which are commercially available under the registered trade marks "Checkpoint" and"Dustite", are produced in at least two sizes for snug fitting to at least these sizes of wheel nut so that the angles of the respective hexagonal nuts fit closely into relevant grooves in the bore of the device.

Bonding Structure And Bonding Method For Cemented Carbide Element And Diamond Element, Cutting Tip And Cutting Element For Drilling Tool, And Drilling Tool - Patent 8147573

Patents-275 — Mon, 16 Apr 2012 07:15:45 GMT

shared by: Patents-275 on: Monday, April 16, 2012

1. Field of the Invention The present invention relates to a bonding method and bonding structure between a cemented carbide element and a diamond element. In addition, the present invention relates to a cutting tip, cutting element, and a drilling tool for drilling awell (winze) or the like. 2. Description of the Related Art Drilling tools are used to drill oil wells and other types of wells. As one such type of drilling tool, a drilling tool is known in which posts made of superhard tungsten carbide alloy (below, referred to as "cemented carbide posts") areattached to the distal surface of an iron alloy tool body in a predetermined arrangement by methods such as brazing and shrinkage fitting, and cutting tips consisting of ultrahigh pressure sintered diamond (below, referred to as "sintered diamond") arebrazed to each of these cemented carbide posts. The drilling tool is mounted on the distal end of a pipe, the pipe is rotated while applying a weight via the pipe in the drilling direction, and thereby drilling is carried out by the cutting tipsprovided on the tool body. Because the wettability of the sintered diamond that forms the cutting tip with respect to the brazing filler metal is low, brazing using a standard brazing filler metal is difficult. In the drilling tool disclosed in Japanese Unexamined PatentApplication, First Publication, No. 2000-000686, an Au alloy brazing filler metal (melting point, 940.degree. C.) having a composition including, for example, Cu at 20 to 40% by mass and Ti at 0.5 to 10% by mass, with the remainder consisting of Au andunavoidable impurities, is used in order to braze a cutting tip to a cemented carbide post. In addition, U.S. Pat. No. 6,248,447B1 discloses a drilling tool in which cutting tips are formed by high heat resistant sintered diamond. In recent years, requirements for labor saving, energy saving, and cost reduction in the drilling operation are increasingly severe. For example, because the operating cost

Thermally Stable Diamond Polycrystalline Diamond Constructions - Patent 8147572

Patents-275 — Mon, 16 Apr 2012 07:15:22 GMT

shared by: Patents-275 on: Monday, April 16, 2012

This invention generally relates to polycrystalline diamond materials and, more specifically, to polycrystalline diamond materials that have been specifically engineered to provide an improved degree of thermal stability when compared toconventional polycrystalline diamond materials, thereby providing an improved degree of service life in desired cutting and/or drilling applications.BACKGROUND OF THE INVENTION Polycrystalline diamond (PCD) materials and PCD elements formed therefrom are well known in the art. Conventional PCD is formed by combining synthetic diamond grains with a suitable solvent catalyst material to form a mixture. The mixture issubjected to processing conditions of extremely high pressure/high temperature, where the solvent catalyst material promotes desired intercrystalline diamond-to-diamond bonding between the grains, thereby forming a PCD structure. The resulting PCDstructure produces enhanced properties of wear resistance and hardness, making PCD materials extremely useful in aggressive wear and cutting applications where high levels of wear resistance and hardness are desired. Solvent catalyst materials typically used for forming conventional PCD include metals from Group VIII of the Periodic table, with cobalt (Co) being the most common. Conventional PCD can comprise from 85 to 95% by volume diamond and a remainingamount solvent catalyst material. The material microstructure of conventional PCD comprises regions of intercrystalline bonded diamond with solvent catalyst material attached to the diamond and/or disposed within interstices or interstitial regions thatexist between the intercrystalline bonded diamond regions. A problem known to exist with such conventional PCD materials is that they are vulnerable to thermal degradation, when exposed to elevated temperature cutting and/or wear applications, caused by the differential that exists between the thermalexpansion characteristics of the interstitial solvent metal catalyst material

Material Containing Diamond And An Intermetallic Compound - Patent 8147574

Patents-275 — Mon, 16 Apr 2012 07:15:06 GMT

shared by: Patents-275 on: Monday, April 16, 2012

This invention relates to a method of generating a diamond containing material (DCM). Diamond-containing material (DCM) used extensively in cutting, milling, grinding, drilling and other abrasive operation, may take many forms, for example: a diamond matrix tool material, where the diamond particles are held together in ametallic or intermetallic matrix. These are typically formed at atmospheric pressure by sintering together the diamond-matrix mixture, and are generally characterised by diamond volume contents that are less than 70 volume %. abrasive compacts, thatconsist of a mass of ultrahard particles, typically diamond, bonded into a coherent, polycrystalline conglomerate. The abrasive particle content of these abrasive compacts is high, generally in excess of 70 volume %; and more typically in excess of 80volume %. There is generally an extensive amount of direct particle-to-particle bonding or contact. Abrasive compacts are generally sintered under high pressure, high temperature (HpHT) conditions at which the diamond is crystallographically orthermodynamically stable. Diamond compacts are also known as PCD. Abrasive compacts also usually have a second or binder phase. In the case of certain types of polycrystalline diamond compacts, this second phase is typically a metal such as cobalt, nickel, iron or an alloy containing one or more such metals. Examples of composite abrasive compacts can be found described in U.S. Pat. Nos. 3,745,623; 3,767,371 and 3,743,489. When diamond particles are combined with a suitable metallic solvent/catalyst, this solvent/catalyst promotes diamond-to-diamond bonding between the diamond grains, resulting in an intergrown or sintered structure. This mechanism occurs in partbecause of the solubility of carbon in the solvent/catalyst which allows carbon from the diamond to dissolve and re-precipitate on other diamonds while in the diamond stable field during manufacture. This results in extensive diamond-to-diamond bondin

CROSS REFERENCE TO RELATED APPLICATION This application claims priority to and all the advantages of International Application No. PCT/CN2008/000648, filed on Mar. 31, 2008, which claims priority to Chinese Patent Application No. 200710021300.8, filed on Apr. 18, 2007.FIELD OF TECHNOLOGY The present invention relates to a power tool, and more especially, to a multi-functional power tool capable of realizing impact wrench function and electric drill function or electric screwdriver set function or impact drill function.BACKGROUND OF THE INVENTION Among the existing power tools, the impact wrench is used to tighten the screw fastener to work piece. It generally comprises a main shaft driven by the rotation of the motor, impact block connected with the main shaft through spiral scroll andball, and working shaft fit for the impact block through the end tooth and located in front of the impact block. An impact spring is configured in the back of the impact block, which compresses the impact block to enable the impact block to keepreliable coordination with the working shaft. During working, the rotation movement of the main shaft directly outputs to the screw piece through the impact block and working shaft so as to secure the screw piece to work piece. During the tightening,the load on the working shaft gradually increases. When the load exceeds the preset value, the impact moves toward the motor relative to the working shaft through the rolling of the ball in the spiral scroll, and compresses the spring behind it. At themoment that the impact block and the end tooth of the working shaft are unfitted, under the action of the impact spring, the impact block moves forward in axial direction and beats the working shaft in rotation direction, so as to enable the workingshaft to keep tightening the screw piece in the direction of rotation. In such cycles, through endless intermittent beating of the impact block, the screw piece can be secured to a work piece in the

Hydraulic Breaker Assembly - Patent 8146677

Patents-281 — Mon, 16 Apr 2012 05:45:55 GMT

shared by: Patents-281 on: Monday, April 16, 2012

The present invention relates, in general, to a hydraulic breaker assembly which improves an assembly structure including a head cap, a cylinder, and a front head, which are assembled in a casing, thereby increasing the durability thereof.BACKGROUND ART As is generally known in the art, a hydraulic breaker includes a head cap having hydraulic passages for supplying and receiving hydraulic pressure, a cylinder having a cylinder chamber, in which a piston is reciprocated, and elements, e.g.valves or the like, for operating the piston, and a front head having a striking rod, which is connected to the piston so as to implement a striking stroke through reciprocating operation. The above constitutional elements are separately formed and arecombined into a single unit by four long bolts. In operation, the piston strikes the rod while moving up and down by means of hydraulic pressure supplied to the cylinder, so that the rod can break a rock or the like. As shown in FIG. 1, a conventional hydraulic breaker 10 in the related art includes a cylinder 50 having a piston therein, a front head 40 installed on a lower end of the cylinder 50 and having a rod 70 therein as striking means, and a head cap30 connected to an upper end of the cylinder 50, wherein the head cap 30, the cylinder 50, and the front head 40 each have through-holes, into which long bolts 80 are inserted so as to connect them. Herein, nuts fastening the long bolts 80 are coupled to the bolts in mounting holes 40-2 provided in the front head 40, and the side faces of the front head, the cylinder, and the head cap are supported by variable dampers 30-1, 30-2, 40-1, and50-1 inserted into the inside of the casing 60. In the breaker 10, when a hydraulic or pneumatic pressure source is supplied to the inside of the cylinder 50, the piston moves down to strike the rod 70 provided in the front head 40, so that the rod 70 in turn strikes and breaks an object. However, such a breaker has a problem in that, when distor

CROSS REFERENCE TO RELATED APPLICATION This application claims priority from Japanese Patent Application Nos. 2008-138430 filed May 27, 2008 and 2008-138431 filed May 27, 2008. The entire content of the priority applications are incorporated herein by reference.TECHNICAL FIELD The present invention relates to a screw driver, and more particularly, to such screw driver having a clutch mechanism and a co-rotation preventing mechanism.BACKGROUND A screw driver is used for driving screws to fix a plate member such as a plaster board to a ceiling or a wall. Laid open Japanese Patent Application Publication No. H5-318331 discloses such screw driver having a driving assembly including amotor, a driven assembly having an end bit mounting portion, and a clutch mechanism that performs frictional power transmission from the driving assembly to the driven assembly. No power transmission to the end bit is performed without generation offriction when the clutch mechanism is rendered OFF, and power transmission to the end bit is performed with the frictional force when the clutch mechanism is rendered ON. According to the power tool disclosed in the Japanese publication, frictional force is generated at the clutch mechanism upon pressing the end bit against a screw. In this case, friction is slightly generated even after turning OFF the clutchmechanism, so that driving force is slightly transmitted to the end bit along with the forward rotation of the motor. Therefore, alignment of the end bit with a groove of a head of a screw becomes difficult to achieve. In order to avoid this problem,an O-ring is interposed between a housing and an end bit mounting portion. However degradation may occur in the O-ring due to long term use, and as a result, the O-ring cannot prevent the end bit from being rotated along with the forward rotation of themotor in spite of turning OFF the clutch mechanism. Particularly, the end bit is reversely rotated by pulling a trigger after simply settin

The positioning unit is disposed on the rod body and includes a protrusion and an engaging portion. The protrusion is allowed to move in the radialdirection of the rod body, and the engaging portion is interactively connected to the protrusion so as to be engaged or disengaged from the socket. The pushing sleeve includes a first end surface and a second end surface in two opposite directions. Thepushing sleeve is further formed with a resisting portion b

Nail Ripper - Patent 8146460

Patents-282 — Mon, 16 Apr 2012 05:27:54 GMT

shared by: Patents-282 on: Monday, April 16, 2012

The invention relates to tools for removing material that has been nailed in place, such as asphalt shingles and roofing materials of all types, and flooring materials such as tile, carpet and wood strips. It is also useful in removing siding,panels, and moldings.BACKGROUND TO THE INVENTION When a building, or part of one, is to be taken apart, if material is to be salvaged, nails must be extracted. Some parts of buildings, notably roofing materials, are intended to be replaced many times in the life of the building. Roofingmaterials, such as shingles, are nailed in place, so removing the shingles for replacement requires extracting the nails. For efficiency, it is normal to lift the roofing material and the nail together, until the nail is fully extracted and the roofingmaterial is detached from the building. The roofing material and the nail can then be discarded, and the wooden roof that has been exposed will be retained, possibly with some repairs, and covered with new roofing material. This description will mainly speak in terms of lifting shingles, for brevity. That is an important use of the tool, but it must be remembered that the tool is useful for removing many types of building materials held by nails. Most nails have heads that provide a grip for a pulling tool. Most pulling tools have a slot to grip the nail below the head, and operate as a lever with the fulcrum on the surface in which the nail is embedded, such as the roof. The commonclaw hammer is an example. Many more elaborate tools have been developed, and patented, but there remains room for improvement in respect of the smoothness of operation in guiding the tool around the nail, and in levering the nail out of the material inwhich it is embedded. U.S. Pat. No. 1,218,145 to Whittier discloses, way back in 1917, a shingle stripper that is a blade having V-shaped slots on the front and back edges, and the bottom surface (and top surface, but that is irrelevant) having two dihedral plan

The present invention relates to mechanical tools and, more particularly, to wrenches and other devices designed to apply pressure to an object placed between two jaws of a tool.BACKGROUND OF THE INVENTION Wrenches and other hand tools often can not exert enough force to grip an object securely. In the case of wrenches, rusted, frozen and undersized nuts are often difficult to remove and become further deformed by the action of the wrench jaws. Wire cutters and other hand tools that apply an increasing force on an object between jaws of a hand tool often lack sufficient mechanical advantage to function with wire of more than a small gage. Pliers, socket wrenches, open end wrenches, vise grips type devices and pipe wrenches are well known. Wrenches which function as an approximation of the nut head, such as open end wrenches and socket wrenches, must by necessity be slightly oversized so that they can accommodate a rusted nut and so that they can be applied and removed easily. This mismatch between the nut head and the wrench face will tend to reduce mechanical efficiency and limit the gripping force exerted upon the faces of the nut. Likewise traditional wire cutters have a limited leverage and force which can be exerted onthe wire or other material to be cut when inserted between jaws of the tool. Vise grip tools enable an adjustable degree of leverage to increase pressure on the object grasped. Problems with the vise grip include high pressure on the handles in order to get a tight grip, a tendency to distort or destroy the surface ofthe object gripped, high pressure required to release the grip, and lack of any feedback or "mechanic's feel" when using the vise grip. Traditional pliers are usually made to fit a large range of sizes of nut or object to be gripped. Conventional pliers are severely limited in the amount of mechanical advantage they provide and often strip nut heads because of the mechanicalforce fed back into the handles when the closed pliers i

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT "Not Applicable"INCORPORATION-BY-REFERENCE OF MATERIAL SUBMITTED ON A COMPACT DISK "Not Applicable"BACKGROUND OF THE INVENTION This invention provides an improved device for assisting in the opening of a wide range of common plastic bottle twist caps by increasing grip and leverage to the cap with an unprecedented ratcheting function that decreases the angulardeflection demands on the user's wrists. Rotation is thus optionally broken down into multiple small movements or less larger movements depending on the user's desire. To maximize effectiveness the device accommodates a wide range of sizes. Since their introduction plastic twist caps continue to be difficult to open for many users. While the integrity of the cap's robust seal ensures against content contamination and leakage, it is often a problem to achieve adequate cap grip totransfer the necessary torque required to break the seal. This is especially true for those with limited strength or physical impairment. Many devices are widely known on the marketplace developed over the years in an attempt to mitigate this trouble. However previous devices have suffered poor effectiveness due to various shortcomings such as limited capability, ease of use,comfort, and or slippage due to a lack of traction or grip. Through an improved design, the current invention eliminates or renders insignificant the shortcomings of the prior devices while adding advantages heretofore not available. The main body of the current invention has a comfortably pleasing shape that, in the preferred exemplary embodiment it includes two separate apertures each offering a different and slightly overlapping range of cap size capability. Locatedbetween the two cap apertures is a center portion housing a single rotatable cam with two contoured surfaces shaped for the purpose of engaging the bottle cap positioned in either aperture. The cam is additionally spring loaded to f

Patents-279 — Mon, 16 Apr 2012 05:07:20 GMT

shared by: Patents-279 on: Monday, April 16, 2012

The invention pertains to the field of compound window balances. More particularly, the invention pertains to a device and method for connecting the extension spring of a compound balance to the torsion spring/spiral rod sub-assembly.BACKGROUND OF THE INVENTION Vertically sliding window assemblies are also known as hung windows and may consist of either a single sash or two sashes, respectively referred to as single hung or double hung windows. A hung window assembly generally includes a window frame,at least one sash, a pair of opposing window jambs, each jamb having a channel for allowing the vertical travel of each sash, and at least one window balance to assist with the raising and lowering of the sash to which it is attached by providing a forceto counterbalance the weight of the sash. Springs are utilized to provide the counterbalancing force and are especially useful for operating very heavy sashes. Compound balances are preferred for facilitating the operation of these very heavy sashes. In compound balances, a torsionspring provides a lifting force over the full travel of the sash through the jamb channel. The torsion spring force is converted into a lifting force by extending an elongated spiral rod. The torsion spring and elongated spiral rod are surrounded by anextension spring. Alternative designs have the sub-assembly encapsulated within a containment tube. It is desirable to have the combined axial forces of the torsion spring of the sub-assembly and extension spring provide substantially constant liftingforce over the full vertical travel of the compound balance. The compound balance has an open end, from which the free end of the spiral rod extends, and a closed end, which is securely fastened to the wall of the jamb channel of the window frame. The open end of the compound balance sub-assembly is often capped by a rotatable coupling having a central opening through which the elongated spiral rod extends. When the free end of the spiral r

1. Field of the Invention The present invention relates to a hinge and an electronic device with the same, especially to a hinge that is rotatable by 180 degrees both clockwise and anticlockwise. 2. Description of the Prior Arts Conventional electronic devices such as notebook computers, cell phones and the like comprise a cover, a base and a conventional hinge. The conventional hinge is mounted between the cover and the base to allow the cover to be tilted and rotatedrelative to the base. To protect internal electrical wires, the conventional hinge has a limiting structure to prevent the cover from over rotating. The limiting structure comprises a stationary limit and a rotating limit respectively connected to thebase and the cover. So when the cover is rotated about a longitudinal axis to adjust a viewing angle of a screen, the rotating limit abuts the stationary limit to limit the rotation of the cover. Conventionally, both the rotating limit and the stationary limit have certain, tangible sizes, and are firmly provided on the cover and base respectively so that those elements, though they prevent the wires from damage, also prevent the coverfrom being rotated clockwise and anticlockwise by 180 degrees relative to the base. There are several ways to overcome the shortcomings, but most require complicated designs so are costly to implement and may not be as reliable in use. Therefore, the present invention provides a hinge and an electronic device with the hinge to mitigate or obviate the aforementioned problems.SUMMARY OF THE INVENTION The main objective of the present invention is to provide a hinge that is rotatable by 180 degrees in two planes. The hinge is mounted between a cover and a base of an electronic device and has a first actuating unit, a pivoting limit and asecond actuating unit. The first actuating unit has two tops. The pivoting limit is mounted pivotally between the stops. The second actuating unit selectively abuts a first side and a

The invention concerns a furniture hinge that has a door stop part that comprises an insertion cup and is attached on a furniture door, on which a pivoting arm that is connected to a furniture body is arranged, and that comprises a dampingdevice having at least one damping cylinder that engages in the door stop part. Particularly during quick closing motions, the closing force that a furniture hinge exerts on the furniture door that is to be closed results in the furniture door slamming shut on the furniture body. In an effort to reduce the impact effectand the resulting noise, it is known to arrange buffers on the furniture body or on the furniture door. However, because said buffers necessarily must be thin, this only results in a minor reduction of the impact effect. Therefore, it is known to arrange a damping device on the furniture hinge with which the furniture door makes contact at the end of its closing motion. The damping device comprises a damping cylinder with whose piston rod the furniture door ora fitting attached thereon makes contact so that the furniture door is slowed down until it is fully closed. Since the damping effect of the damping cylinders is velocity-dependent, the damping device does not exert any force on the furniture door whenthe furniture door is closed, which means that the furniture door stays in the closed position. In a known furniture hinge as described in the introduction (EP 1 538 293 B1) the damping device is arranged on the stop part of the body and engages with the door stop part. In another known furniture hinge equipped with a damping device (US2004/0205935 A1) as described in the introduction, the piston rod of the damping cylinder of the damping device arranged on the body stop part extends in the direction of the furniture door. When the furniture door is being closed, its door stop partmakes contact with the exposed end of the piston rod so that the motion of the furniture door is dampened. The known embodiments

Rug Anti-slip Device - Patent 8146202

Patents-279 — Mon, 16 Apr 2012 05:06:24 GMT

shared by: Patents-279 on: Monday, April 16, 2012

1. Field of the Invention This invention relates generally to floor coverings and accessories therefore and, more specifically, to a Rug Anti-slip Device. 2. Description of Related Art There have been several attempts at solving the problem of holding mats or rugs in place atop a carpeted floor area. Dichtel, U.S. Pat. No. 4,860,402, for a "Carpet Mat Retainer Clip" discloses a metallic, spring-like clip that grasps theedge of the rug and holds that rug edge to the carpet. U.S. Pat. No. 1,598,127 to J. G. Fleming discusses a "Corner Piece for Rugs" that is designed to prevent the corners of a rug from curling up when the rug is placed atop a polished floor surface, like a hardwood floor. The "Automobile Mat and Securing Clip" device awarded U.S. Pat. No. 5,003,664 to Wong is a metallic pin that pins through the carpet surface. Cooperating sections of hook-and-loop fastener material on the top surface of the Wong clip and thebottom surface of the automobile mat releasibly attach to one another in order to hold the mat in its desired location. U.S. Pat. No. 581,634 to I. N. Veal for a "Rug Fastener" is a two-piece pin/clip assembly that pins through the carpet and then clips to a device attached to the underside of the rug. The "Carpet Fastener" of N. M. Harrison, U.S. Pat. No. 493,401 is, essentially, a specialized safety pin that pins through the rug and carpet and then attaches to itself (to safely protect the protruding pin tip). Finally, the "Rug Anchor" of U.S. Pat. No. 5,761,765 to Fuzzell is a device having upwardly-turned teeth and downwardly-turned teeth on its respective top and bottom surfaces. The Fuzzell device is placed between the rug and carpet and theteeth engage both to keep the rug from moving. While each of these devices may serve the purposes that their respective inventors sought to serve, that is to prevent movement of a rug, none seems to have achieved any real penetration into the market. It is believed that this is because

The present application is a 35 U.S.C. .sctn.371 national phase application of PCT International Application No. PCT/GB2007/050358, having an international filing date of Jun. 26, 2007, claiming priority to Great Britain Patent Application No.0613343.3, filed Jun. 30, 2006. The disclosures of each application are incorporated herein by reference in their entireties. The above PCT International Application was published in the English language and has International Publication No. WO2008/001131A1.BACKGROUND OF THE INVENTION The present invention relates to castor wheel assemblies, in particular but not exclusively, to castor wheel assemblies of a type suitable for use with trolleys, for example supermarket trolleys or luggage trolleys. It is known to fit castor wheels, in particular swivel castor wheels, to a variety of vehicles including trolleys or carts for use in warehouses, hospitals and retail establishments for use in transporting goods or persons. In order to provide a high level of maneuverability, swivel castor wheel assemblies are typically provided at each of four corners of the vehicle so that the vehicle may be pushed in any direction over a floor. For example, a vehicle may bepushed in a forward direction, a backward direction, or sideways. The problem exists, however, that such vehicles lack directional stability. This can lead to difficulties in maneuvering a vehicle such as a shopping trolley or cart, which may in turnlead to accidental collisions and possible injuries. It is helpful to consider the geometrical factors involved. In the field of motorcycle engineering, it is usual to speak in terms of the rake and the trail of the front steering system. Rake is the angle measured between the steering axis andvertical. The steering axis is the line about which the steering system turns. Trail is the distance measured from where the steering axis meets the ground to where a vertical line drawn though the front axle meets the ground. It ca

Patents-279 — Mon, 16 Apr 2012 05:06:08 GMT

shared by: Patents-279 on: Monday, April 16, 2012

The present invention relates generally to hinges and, more particularly, to hinges used on container doors and the like.BACKGROUND OF THE INVENTION Access doors for containers, such as shipping containers, semitrailers, and the like, are typically hinged at one side and secured via a bar lock. The bar lock is typically pivotally mounted opposite the door hinges and is positionable betweenan open or unlocked position, and a closed or locked position. In the locked position, the bar lock is typically held in position by a shackle, a seal, a padlock, or the like. However, the hinges to which the bar lock is pivotally mounted may havefasteners, such as screws or bolts, that are readily accessible and/or removable, such that the bar lock may be defeated by removing the hinges rather than tampering with the shackle, seal, or padlock.SUMMARY OF THE INVENTION The present invention provides an anti-tamper member or plate that is fixedly attached to a hinge, such as the hinge of a bar lock system, in order to prevent access to the fasteners of the hinge when the bar lock is in a closed or lockedposition. The anti-tamper member substantially covers the fasteners of the hinge in order to discourage or prevent access to the hinge fasteners, thus improving the security of the bar lock. According to one form of the present invention, the tamper resistant hinge includes a hinge plate, at least one fastener, and an anti-tamper member. The fasteners couple the hinge plate to a mounting surface, such as a door or a wall. Theanti-tamper member substantially covers and protects the fasteners in order to inhibit access to the fasteners, thereby limiting or substantially preventing removal of the fasteners and the hinge. According to another form of the present invention, a tamper resistant hinge, such as for a bar lock assembly on a shipping container or trailer, includes a hinge plate, at least one fastener, a hinge pin, a pivot arm, and an anti-tamper member. The hinge plate de

The instant invention relates to automotive rescue tools and more particularly to a pre-planned, organized life-safety system for self-removal of occupants from within the confines of a vehicle when the occupant space is deemed, or expected tobecome Immediately Dangerous to Life and Health (IDLH).BACKGROUND OF THE INVENTION There are numerous rescue tools presently in existence. U.S. Pat. No. 6,551,159 to Spinelli covers the shortcomings of many examples of the prior art very well. These examples are incorporated herein by reference to Spinelli. However, Spinelli's own shortcomings exist primarily in the fact thatSpare Air.TM. and their like containers of compressed air are very solid in order to actively contain the compression of the air inside. These solid and heavy objects in a violent collision can fly around the passenger compartment, striking occupantson the head as well as causing immobility and injury to the user's hands & fingers. Spinelli's system heightens the danger to the situation and ironically leaves the user in greater harms way than originally presented with. Spinelli is a self-evacuation tool focusing on compressed air breathing apparatus. Although Spinelli does have peripheral window breaking and seatbelt cutting tool, its main focus is on underwater breathing and not the multi-task-orientedself-evacuation of occupants in all automotive emergencies. It and prior art fail to address the usability of said devices with automotive emergencies involving collision induced entrapment of occupants under heat, smoke, and toxic gas environments inaddition to underwater incidents. Obstruction of the primary path of egress, the low visibility environment, the buoyancy of rescue equipment as well as precautions taken for anti-slip hand surfaces and waterproof capabilities have all been recklessly ignored in prior art. Thisis unacceptable and is caused partly because the safety standards of other mandated fields pertaining to the preservation and s

Patents-275 — Sun, 15 Apr 2012 22:27:14 GMT

shared by: Patents-275 on: Sunday, April 15, 2012

BACKGROUND Abrasive particles and abrasive articles made from the abrasive particles are useful for abrading, finishing, or grinding a wide variety of materials and surfaces in the manufacturing of goods. As such, there continues to be a need forimproving the cost, performance, or life of the abrasive particle and/or the abrasive article. Triangular shaped abrasive particles and abrasive articles using the triangular shaped abrasive particles are disclosed in U.S. Pat. Nos. 5,201,916 to Berg; 5,366,523 to Rowenhorst; and 5,984,988 to Berg. In one embodiment, the abrasiveparticles' shape comprised an equilateral triangle. Triangular shaped abrasive particles are useful in manufacturing abrasive articles having enhanced cut rates.SUMMARY Shaped abrasive particles, in general, can have superior performance over randomly crushed abrasive particles. By controlling the shape of the abrasive particle it is possible to control the resulting performance of the abrasive article. Theinventors have discovered that by making the shaped abrasive particle with a sloping sidewall having a draft angle between about 95 degrees to about 130 degrees several unexpected benefits occur. First, the shaped abrasive particles with the sloping sidewall tend to rest on the make coat of a coated abrasive article at an angle corresponding to the draft angle of the sidewall. It is believed that a draft angle other than 90 degreesresults in the shaped abrasive particles leaning instead of having a 90 degree orientation to the backing in a coated abrasive article since the sidewall, which the shaped abrasive particle in the coated abrasive rests on, is sloped due to the draftangle. Because the shaped abrasive particles are mostly tipped or leaning to one side due to the angled sidewall they rest on, they can have an orientation angle less than 90 degrees relative to the backing thereby enhancing cut rates. Secondly, the shaped abrasive particles with the sloping sidewall can have differen

BACKGROUND Abrasive particles and abrasive articles made from the abrasive particles are useful for abrading, finishing, or grinding a wide variety of materials and surfaces in the manufacturing of goods. As such, there continues to be a need forimproving the cost, performance, or life of the abrasive particle and/or the abrasive article.

Triangular shaped abrasive particles are useful in manufacturing abrasive articles having enhanced cut rates.SUMMARY Shaped abrasive particles, in general, can have superior performance over randomly crushed abrasive particles. By controlling the shape of the abrasive particle it is possible to control the resulting performance of the abrasive article. Theinventors have discovered that by making the shaped abrasive particle with an opening, hole or aperture several unexpected benefits occur. First, the shaped abrasive particles with an opening have an enhanced cut rate as compared to similarly shaped abrasive particles without an opening. Without wishing to be bound by theory, it is believed that the enhanced cut rate results froma reduction in the size of the wear flat as the shaped abrasive particle is used. As shaped abrasive particles wear, typically a larger and larger wear flat appears on the working surface of the shaped abrasive particle dulling the shaped abrasiveparticle. In contrast, as the shaped abrasive particles with an opening wear, the size of the wear flat initially increases until the shaped abrasive particle is worn through to the opening. At that point, the presence of the opening effectivelyreduces the total size of the wear flat by creating two smaller wear flats instead of the single larger wear flat previously pr

This invention relates to self-attaching female fasteners, including pierce and clinch nuts, for an attachment to a panel in a press which may be formed by cold header techniques.BACKGROUND OF THE INVENTION Self-attaching female fasteners, including pierce and clinch nuts, formed by cold header techniques and secondary press operations generally include a body portion having an end face, a central pilot portion projecting from the end face of thebody portion having a bore through the central pilot portion, a flange portion surrounding the outer surface of the pilot portion including an annular groove surrounding the pilot portion and an annular planar panel support surface surrounding theannular groove. The bottom wall of the annular groove typically includes a plurality of circumferentially spaced convex or concave radial ribs which provide resistance to rotation of the nut or torque resistance following installation in a panel. Inmany applications, torque resistance is an important feature of the self-attaching nut. The outer surface of the flange portion is typically round or polygonal having six or more sides. U.S. Pat. Nos. 5,531,552, 5,549,430, 6,851,904, 6,994,500,7,001,125, 7,112,024, 7,112,025 and 7,112,142 all assigned to the assignee of this application disclose this type of fastener.

This Application claims priority to U.S. Non-provisional application Ser. No. 11/385,975, filed on Mar. 21, 2006, which claims priority to U.S. Provisional Application No. 60/759,045, filed on Jan. 17, 2006, both of which are incorporatedherein by reference in their entirety.FIELD OF THE INVENTION The present invention relates to wall anchors and, more particularly, to anchors suitable for both hollow and solid walls.BACKGROUND OF THE INVENTION Various wall anchors exist for hollow walls, including self-installable anchors and expandable anchors. Some of these anchors define outer threads adapted to engage the friable material that constitutes part of the wall structure, such as inU.S. Pat. No. 5,833,415 issued on Nov. 10, 1998 to McSherry. Other such anchors include a toggle member that is adapted to pivot between a longitudinal insertion position and a transversal retention position, wherein the toggle member adopts itstransversal position once behind the wall, so as to then be drawn towards the wall until it engages a rear hidden surface of the hollow wall, thereby firmly securing the anchor to the hollow wall, such as in U.S. Pat. No. 6,250,865 issued on Jun. 26,2001 to McSherry. Anchoring devices encounter various wall mediums, such as hollow walls and solid walls, and in the case of the former, the thickness of the hollow wall may vary. Anchoring devices thus need to have constructions suitable for such mediums. The present invention seeks to meet these needs and other needs.SUMMARY OF THE INVENTION More specifically, it is therefore an aim of the present invention to provide a novel anchoring device. It is also an aim of the present invention to provide an anchoring device adapted for various wall constructions, including hollow walls of various wall thicknesses. It is a further aim of the present invention to provide an anchoring device adapted for various wall constructions, such as hollow walls and solid walls. It is still a further aim of t

CROSS-REFERENCES TO RELATED APPLICATIONS This application claims the benefit of U.S. patent application Ser. No. 10/772,662, filed Feb. 5, 2004, the contents of which are hereby incorporated by reference herein.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to anchors and anchoring methods, and in particular, to anchors using rotating hubs. 2. Description of Related Art Cargo can shift when being transported by an automobile, van, truck, boat, airplane, or other vehicle. The cargo can be damaged and may produce distracting noises during transport. In some cases shifting cargo can cause a load imbalanceaffecting the steering of the vehicle. In still other cases, shifting cargo may shift so much as to strike and injure a vehicle occupant. For this reason, cargo is often tied down with straps or cords and vehicles are often provided with cleats or other structure for this purpose. However, in many cases the vehicle has inadequate tiedown structure or the cargo may have an unusualshape making tiedown difficult. For example, a small object adjacent a large one may require a separate tiedown in the middle of a cargo floor. However, scattering multiple tiedown structures across a cargo floor is impractical, especially when theneed for such intermediate tiedown structure is rare. Moreover, even if many tiedown structures are scattered throughout the vehicle, the tiedown points are still discrete and finite, and one cannot finely adjust the position of the tiedown point. In the absence of tiedown structure, a vehicle can be retrofitted with hardware facilitating the securing of cargo. This will often require drilling mounting holes that may weaken the vehicle's structure or compromise noise or weatherinsulation. Moreover, if cargo transport is infrequent, such tiedown structure can be obtrusive. Anchoring objects to carpets or other fibrous material can be problematic. In particular, one would like to avoid cutting or alter

Multi-piece Fastener With Self-indexing Nut - Patent 8142126

Patents-278 — Sun, 15 Apr 2012 21:45:18 GMT

shared by: Patents-278 on: Sunday, April 15, 2012

The present invention relates generally to a method and apparatus for improving installation of joint elements in limited clearance situations, and more particularly to a method and apparatus utilizing a multi-piece fastener to secure jointelements.BACKGROUND Aerospace and military applications often provide unique challenges to design and manufacturing. Often manufacturing requires the assembly of multiple elements within regions providing limited clearance and reduced accessibility. Traditionalattachment methodologies and fasteners may be difficult to position within such regions. In addition, assembly of such structures commonly requires precise tensioning of such fasteners to minimize stresses and insure proper functioning. The use oftraditional fasteners, such as commonly used bolt assemblies, can result in difficult installation, ergonomic issues, inconsistent torque application, and sub-optimum joint fatigue performance. One such assembly that suffers from the aforementioned concerns is the wing side-of-body joint assembly used in aerospace applications. The wing side-of-body joint is configured around chordwise stiffeners, typically referred to as chords, usedto transmit wing skin and stringer loads into the body and wing center structure. Presently, the fasteners used in this application are high strength protruding head bolts and nuts. The limited clearance present in the chord elements, however, dictatesundesirable constraints on how the bolts may be orientated and their installation sequence. Often, limited clearance may make traditional bolt assemblies virtually impossible to utilize or re-torque after installation. It is also highly desirable to torque bolts from the nut side. Such nut-side torque application is known to deliver consistent optimum joint fatigue performance. Torque application from the head side often results in the bolt turning insidethe hole, which can score the bolt and/or fastener and result in galling and improper bolt t

Patents-278 — Sun, 15 Apr 2012 21:44:59 GMT

shared by: Patents-278 on: Sunday, April 15, 2012

The invention relates generally to torque nuts, and more particularly to a torque nut assembly that can be quickly coupled to or uncoupled from a threaded fastener without requiring the threading or unthreading thereof.BACKGROUND OF THE INVENTION Threaded torque nuts and threaded bolt/screws are used in combination to fasten a wide variety of parts. However, the length of a bolt and/or thread density per unit length can greatly affect the amount of time it takes to screw a nut onto abolt or unscrew a nut from a bolt. In applications where this service operation needs to be performed quickly, the use of conventional threaded nuts and bolts can have a considerable impact on service turnaround times.SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a torque nut assembly that can be rapidly installed on a threaded fastener and removed therefrom. Another object of the present invention is to provide a torque nut assembly that can be rapidly installed on a bolt, tightened to a specified torque, and be rapidly removed from tightened to a specified torque, and be rapidly removed from itstorqued position on the bolt. Other objects and advantages of the present invention will become more obvious hereinafter in the specification and drawings. In accordance with the present invention, a torque nut assembly includes a nut body and a ring-shaped compression assembly. The nut body has multiple pieces positionable to define a threaded axial passage. The nut body is also separable whenit experiences radial expansion such that the threaded axial passage is segmented in correspondence with the nut body's multiple pieces. The compression assembly circumferentially engages the nut body to capture its multiple pieces therein. Thecompression assembly is movable between a first position and a second position. The first position permits radial expansion of the nut body's multiple pieces and the second position positions the multiple pieces to

This invention relates generally to fastening systems and more particularly, to methods and systems for captive fasteners with integrated lock washer system. Assembly of large structures such as space stations, drilling platforms, and precision clearance machinery requires a strict accounting of assembly hardware to ensure stray hardware do not cause damage to the assembled structure. For example, anut or bolt drifting away from a space station may become a long term projectile hazard for subsequent spacecraft in the vicinity of the space station. A bolt dropped into a reduction gear may cause damage to the gears of jamming of the machinery suchthat it is no longer operable. Retrieving the hardware after is has been dropped or otherwise lost is often difficult if not impossible. This is notable in erecting undersea structures, isolated structures and recently structures for the internationalspace station.BRIEF DESCRIPTION OF THE INVENTION In one embodiment, an integrated captive fastener system includes an integrated nut assembly configured to be tethered to a first structure, the nut assembly including at least one of a lock washer and a flat washer coupled to a nut using aretainer, and a bolt configured to be tethered to at least one of the first structure and a second structure, the nut assembly configured to be threadably couplable to the bolt. In another embodiment, a method of assembling a captive fastening system includes coupling at least one of a flat washer and a lock washer to a nut using a retaining member forming a nut assembly, threading the nut assembly onto a bolt, andapplying a torque to the nut to compress the lock washer between the nut and the flat washer. In yet another embodiment, a captive fastener system for securing two components to one another includes an integrated nut assembly including a lock washer and a flat washer loosely coupled to a nut using a retainer threadably coupled to thenut, a bolt configured to be threadably couplable

The invention relates to a nut-like element for fixing in an interior space of a profile or suchlike workpiece, having a longitudinal extent exceeding the width of an insertion cross section, in particular a connecting device for connecting afirst workpiece having the interior space to another workpiece by means of a screw or suchlike member, the shank of which passes through an opening of the workpiece and can be inserted into a recess of the nut-like element, which is located in theinterior space of the workpiece and is made of a metallic material. In particular in the case of metallic hollow bodies whose interior space is not accessible from outside, the fastening of a profile or the like by a screw still involves difficulties. It is certainly known to fix pictures, shelves or the like to hollow walls of buildings using screws by inserting a plastic plug into the cavity behind a hole, said plastic plug then being deformed by an inserted hook, a screw or the like andbeing brought to bear as an abutment against the inner surface of the wall. However, it is not advantageous to use such plastic plugs when in particular metallic profiles of the type described are to be connected to one another. Publication DE-GM 92 15 843 of the applicant, for example, discloses an element of the type described at the beginning. This sliding block is of roughly parallelepiped design and has at least two flank walls, located opposite one another andinclined at an angle, and a spring member which is fixed at one end on one of the flank walls and reaches across the narrower surface of the element with its free end; the latter is arranged at a distance from a surface of the sliding block in therelaxed state of the spring member. In the knowledge of this prior art, the aim of the invention is to provide nut-like elements of the type mentioned at the beginning which firstly largely simplify the insertion into a hollow body and secondly can be produced in a favorablemanner.SUMMARY OF THE

Device For Holding The Head Of A Toothbrush - Patent 8141958

Patents-276 — Sun, 15 Apr 2012 21:30:29 GMT

shared by: Patents-276 on: Sunday, April 15, 2012

The present invention relates to a device for securing the head of a toothbrush in a processing machine. Conventional toothbrushes comprise a toothbrush head, a toothbrush neck, which adjoins the head, and a toothbrush handle, which adjoins the neck. The part which gives the structure of the toothbrush head, and in particular the part whichreceives the bristles, is usually produced from a rigid plastic, for example polypropylene. The toothbrush head may also have a flexible plastic material. In the case of a known, conventional tufting method, bristle clusters curved in a u-shaped mannerare anchored, by means of metal plates, in holes in that part of the brush head which consists of rigid plastic. During this tufting process, the toothbrush heads are secured by means of retaining devices. As is known, for example, from WO-A-98/58563,these retaining devices may have a retaining plate, which interacts with the free end of the toothbrush head, and two clamps, which act in the region of transition between the toothbrush neck and the toothbrush head and can be moved from a receivingposition into a clamping position. These clamps may be formed in a concave manner in order to enclose the toothbrush head from the side. The front side of the toothbrush head with the holes for receiving the bristle clusters remains free, while therear side of the toothbrush head is supported, in order to counteract the forces which occur during the tufting operation. Reliable, secure retention of the toothbrushes on the toothbrush head and precise positioning are particularly important, in particular, in the tufting machine in order that the tufting tool can readily come into contact with the molded holes inthe toothbrush head. Following the tufting process, the bristles are usually cut to the desired length and then ground in order to round off the ends. Since it is also possible for the toothbrush head to be subjected to considerable forces during thesefinishing processes, in part

1. Field of the Invention The present invention relates to a tool, and more particularly to a quick assembly pneumatic tool that is convenient for assembly and maintenance. 2. Description of Related Art Pneumatic or air-driven impact wrenches are extensively used to rapidly fasten or loosen bolts or nuts. A conventional pneumatic impact wrench has a housing, a rear cover, an air cylinder and an impact assembly. The housing is formed as one piece and has a handle and a barrel. The handle has an air inlet and a trigger assembly. The air inlet is selectively connected to an air supply providing compressed air to the housing through the air inlet. Thetrigger assembly selectively opens or closes the inlet. The barrel is formed on and communicates with the handle and has a front end, a rear end and a chamber. The rear cover is mounted on the rear end of the barrel to seal the chamber. The air cylinder is mounted in the chamber and has a cylinder casing and a rotor. The cylinder casing is mounted securely in the chamber and has multiple air through holes defined therethrough to allow compressed air to enter the cylindercasing. The rotor is mounted rotatably in the cylinder casing and is driven to rotate by the compressed air. The impact assembly is mounted in the chamber of the housing adjacent to the front end, is connected to the rotor and has a transmission member, an anvil and multiple hammers. The transmission member is connected to and selectively driven torotate by the rotor. The anvil, also called a transmission shaft, is mounted longitudinally through the transmission member, protrudes out of the front end of the barrel and may be connected detachably to a tool bit such as screwdriver. The hammers aremounted pivotally on the transmission member and impact the anvil when the transmission member is rotated so that the impacted anvil acquires torque to substantially rotate synchronously with the rotor and the transmission member.

Hammer Having A Two Part Body - Patent 8141655

Patents-281 — Sun, 15 Apr 2012 21:08:21 GMT

shared by: Patents-281 on: Sunday, April 15, 2012

The present disclosure relates generally to a tool assembly, and more specifically to a hammer assembly having a two part body comprising an upper housing member and a lower housing member.BACKGROUND Hydraulic hammers are used on work sites to break up large hard objects before such objects can be moved away. Hydraulic hammers may be mounted to back hoes or excavators, or may be hand-held. Typically, the hammer assembly is powered byeither a hydraulic or pneumatic pressure source. During a work or power stroke, high fluid pressure is applied to a first shoulder of a piston, thereby driving the piston in a forward direction. The piston then strikes a work tool, which is driven inthe forward direction thereby causing a work tip of the tool to strike the rock, concrete, asphalt or other hard object to be broken up. During a return stroke, fluid pressure is applied to a second shoulder of the piston in order to return the pistonto its original position. The work tool, also known as a tool bit, is retained within a sleeve, commonly referred to as a front head. When the tool is driven forward, the kinetic energy of the tool is transferred to the object to be broken up. However, if full contactwith the object to be broken up does not occur, a proportion of the energy is transferred to the front head. If no contact takes place with the object to be broken up, then all of the energy may be transferred to the front head. Consequently, the fronthead is subject to cyclical loading which tends to pull it away from the cylinder of the hammer assembly. Conventionally, external tie rods are used to tie the front head to the cylinder. The tie rods increase the overall diameter of the hammerassembly and add to the complexity of manufacture. Tie rods typically have to be replaced at regular service intervals, since they are subject to fatigue failure and failure of a tie rod can cause irreparable damage to the entire hammer assembly.SUMMARY OF THE INVENTION A method may c

shared by: Patents-282 on: Sunday, April 15, 2012

1. Field of the Invention The present invention relates generally to tools used in the plumbing trade, and more particularly to a powered adjustable pipe wrench for use with threaded pipe and threaded pipefittings. 2. Description of the Related Art The current practice of attaching, tightening, loosening, and removing threaded pipe components to one another is a manual process, with two pipe wrenches normally being employed. One pipe wrench is adjusted and attached to grip the threadedfirst component, e.g., a pipe fitting, etc., and rotate the component in the desired direction. The second pipe wrench is adjusted and attached to grip the second component (pipe or fitting, etc.) to rotate the second component in the oppositedirection, or to hold the pipe while the first wrench is used to rotate the first component, in order to thread or unthread the two components to or from one another. This process is normally performed by a person manually pushing and pulling thehandles of the pipe wrenches together to compensate for torque. When a suitable fixed object is available in close proximity to the work being performed, the handle of one pipe wrench may be braced against the fixed object while the second pipe wrenchhandle is rotated toward or away from the first pipe wrench to perform the desired threading or unthreading of the two pipe components. This operation often requires the exertion of significant human physical force for proper performance, and may result in injury to the person performing this function, as well as injury to helpers or bystanders. This is all the more so whenthis process is performed while the worker is standing on a ladder, scaffold or lift, and the pipe assembly is overhead. This operation may also be performed while standing on the ground employing clamping tables or threading machines to clamp or holdeither the pipe or the pipe fitting, and the mating pipe or fitting is gripped with a pipe wrench. Working on the ground using clampi

BACKGROUND The installation and testing of public water distribution systems are typically regulated by federal, state and local governments. Water distribution systems usually include relatively large distribution lines or pipes called water mains. Theregulations governing the installation and repair of water distribution systems often mandate connections, or service taps, to be installed in the water mains at certain intervals to enable, among other things, chlorination of the system prior toservice, water pressure testing prior to service, and access to the system during service. Connections to a water main for service lines 2 inches or smaller are called corporation stops. Such connections are typically made using approved hardware, such as a Mueller H-15000, for example. Many such connections are intended to betemporary, and these temporary connections are known as blow-offs. Blow-offs may be used for testing purposes and may be removed after testing of the system is complete and prior to placing a water main into service. Prior to putting a water main into service, regulations often dictate that the water main be sanitized or disinfected with chlorine or another disinfectant. Chlorine is inserted into the system via a first blow-off and flushed through the watermain with water. A portion of the water may be removed at a downstream blow-off, and the water may be tested for contaminants. Another test typically which may be performed, prior to putting a water main into service, is a water pressure test. Water is forced through the system at a known water pressure, and gauges may be installed at various downstream corporationstops to test the water pressure at different locations throughout the system. During installation of the system, the water mains and corporation stops are typically laid out in large trenches. Upon installation, the trenches may be filled in with earth, thereby burying the water distribution system beneath the surface ofthe ground.

Hammer Head With Recessed Traction Striking Surface - Patent 8141458

Patents-282 — Sun, 15 Apr 2012 20:52:33 GMT

shared by: Patents-282 on: Sunday, April 15, 2012

The present invention relates to hand tools, and more particularly, to a traction striking surface feature provided on the head of a framing hammer, accommodating a demand for a more resilient and wear resistant traction surface, as well asaddressing the need for two different hammers for rough framing and finish trim work, thereby improving the versatility of claw hammers. Hand held striking tools, such as claw hammers, have been used for centuries by people performing a great variety of tasks associated with carpentry. Typically, steel and titanium framing and finish hammers are used to deliver a striking forceto drive nails into wood and other materials. The claw of a hammer is used, for example, to pull nails from said materials, or to pry materials apart that have been nailed together. Concerning the traction surface of a striking face of a hammer and the commonly used materials for making hammer heads, there is a correlation between the weight, durability, and the practical application of different materials used in makinghammer heads. Framing and trim hammers alike are typically made of steel or titanium, and the mass of the head, when swung by a person, creates a force to drive a nail into a given material, most commonly wood. Framing hammers, in particular, have a specially formed traction surface formed into the striking face of the hammer, for providing a better "grip" on the nail being struck, and preventing the face of the hammer from glancing or sliding off thehead of the nail as readily. This "waffle type" textured pattern or knurled surface used for traction greatly increases the nail driving efficiency of a framing hammer. Framing hammers are so named, particularly, because they are used mostly in roughframing applications of carpentry, where surface damage caused to the wood by the traction surface is of no consequence to the finished product being framed. There are, however, many applications in rough carpentry where work is done with finish

Patents-279 — Sun, 15 Apr 2012 20:31:38 GMT

shared by: Patents-279 on: Sunday, April 15, 2012

1. Field of the Invention This invention relates to jerk handles for lanyards of manual inflators or the manual portion of automatic inflators. 2. Description of the Background Art As the term is commonly employed, a "jerk handle" is a handle connected to the trailing end of a lanyard composed of a cord. The standing end of the lanyard cord is then operatively connected to a device that requires manual actuation uponpulling of the jerk handle. A common application for jerk handles is in the inflation art. In the inflation art, a manual inflator (or the manual portion of an automatic inflator) is connected to an inflation valve of a cartridge of compressed gas. The assembly is then sealingly connected to an article to be inflated. Typical articles may include an inflatable life vest or life raft. To inflate, the user simply grasps the jerk handle and gives it a jerk to manually actuate the inflator causinginflation of the inflatable article. Heretofore, the trailing end of a length of lanyard cord is molded in situ with the jerk handle to form the lanyard. U.S. Pat. No. 5,099,546, the disclosure of which is hereby incorporated by reference herein, discloses a mold-in-situ jerkhandle for inflators. In this form, the lanyard is typically shipped to the manufacturer of the inflator who then assembles it by operatively coupling the standing end of the lanyard cord to the inflator in a manner dictated by the particular design ofthe inflator itself. It is often desirous to have a supply of lanyards with different lengths of cords and therefore there exists a need in the industry for the ability for the inflator manufacturer to assemble the jerk handle to the trailing end of the cord asneeded instead of having to purchase the assembly molded in situ. U.S. Pat. No. 5,347,685, the disclosure of which is hereby incorporated by reference herein, discloses an assemblable jerk handle comprising a channel in which the lanyard cord ispositioned and then secured by me

BACKGROUND 1. Technical Field The exemplary embodiment relates to hinge mechanisms and, particularly to hinge mechanisms used in portable electronic devices. 2. Description of Related Art Portable radiotelephones having two housings joined by a type of hinge that allows the housings to fold upon one another are known in the art. Some folding radiotelephones have most of the electronic components installed in one housing calledthe main housing and fewer electronic components installed in the other housing, called the cover. Other folding radiotelephones may have all electronics components installed in the body with the cover serving only to cover the keypad, or both keypadand display of the phone. Some known portable cellular radiotelephones utilize a hinge mechanism having a spring, a cam and a follower assembled into a cylindrically hollow can via an open end thereof and held in assemblage by a cap coupled to the can over the open end. The assembled hinge is disposed in a cavity of cover and a cavity of body. This hinge mechanism may be desirable to some radiotelephone manufacturers because it can be purchased as a separate unit, thereby eliminating the steps associated withassembling the hinge during manufacturing. However, the number of parts used is large and the cost of the hinge mechanism is high. Therefore, there is room for improvement within the art. BRIEF DESCRIPTION OF THE DRAWINGS Many aspects of the embodiments can be better understood with references to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles ofthe exemplary hinge mechanism and portable electronic device using the hinge mechanism. Moreover, in the drawings like reference numerals designate corresponding parts throughout the several views. Wherever possible, the same reference numbers are usedthroughout the drawings to refer to the same or like elements of an embodiment.

1. Field of the Invention The present invention relates to a two-stage type torsion pivot hinge, and especially to a pivot hinge mounted on a set of foldable electronic equipment to allow a screen to have a larger supporting force when it is opened and get its workingangular position, while only a smaller force is needed for opening, but a larger force is needed for closing to prevent impact. 2. Description of the Prior Art On a set of foldable electronic equipment such as a notebook, pivot hinges must be used to connect a screen to the main body of a key board, so that the screen can be rotated taking the pivot hinges as a center for opening or closing relative tothe key board. The torsion force provided for a common pivot hinge is constant when in opening at any angular position, that is, a user shall use the same force to rotate the screen, overly large torsion force will render uneasy of opening, while overly smalltorsion force will make the screen be subjected to falling down, and to resulting impact in closing. Particularly, following evolving of computer operational systems, it is the probable coming tendency of development to directly install touch controlled displaying screen in a notebook for the convenience of use of a user. Therefore, for thepurpose of meeting the coming tendency, it is necessary to innovate a two-stage type torsion pivot hinge, in order that there is a larger supporting force for a screen when it is at a position to be opened, so that a user is convenient to operate thetouch controlled screen without having the screen being shaken or falling down. In a preceding U.S. Pat. No. 7,124,473 titled "HINGE FOR A NOTEBOOK COMPUTER", a two-stage type torsion pivot hinge was provided. The case disclosed a pivot hinge to be mounted on a notebook and having a function of opening a screen in twostages, the pivot hinge includes a fixing seat fixed on the main body of the notebook, and is provided thereon with a passage and an barrel in communi

Safety Structure Of An Auto-eject Pull Handle For Travel Bag - Patent 8141204

shared by: Patents-279 on: Sunday, April 15, 2012

1. Field of the Invention The present invention relates to an auto-eject pull handle for a travel bag and more particularly, to a safety structure installed in an auto-eject pull handle for a travel bag to prohibit accidental ejection of the pull handle. 2. Description of the Related Art The design of a travel bag must consider many factors. In addition to light and durable characteristics, the factor of ease-of-use is also important. For example, a travel bag is usually equipped with a retractable pull handle to facilitate hand carrying. As shown in FIG. 1, the retractable pull handle 1 is installed in the back side of the travel bag. When not in use, the retractable pullhandle 1 is received inside the housing 2 of the travel bag with the grip 1a exposed to the outside. The housing 2 has a top recess 2a for accommodating the grip 1a, maintaining the whole sense of beauty of the travel bag. However, the limited space between the grip 1a and the bottom wall 2b of the top recess 2a does not allow insertion of a hand. Pulling the grip 1a out of the top recess 2a is not easy. To overcome this problem, an ejecting mechanism (notshown) is provided and locked in the pull handle 1. By means of pressing a control button 3 to unlock the ejecting mechanism, the ejecting mechanism ejects the pull handle 1 upwards from the top recess 2a to a predetermined elevation (see the imaginaryline shown in FIG. 1). Thus, a big space is left between the grip 1a and the bottom wall 2b of the top recess 2a for the insertion of a hand to pull the pull handle 1 to the extended position. According to the aforesaid arrangement, the control button 3 is exposed to the outside for convenient operation. Because no safety means is provided to prohibit accidental triggering of the control button 3, the control button 3 may be forcedto unlock the ejecting mechanism accidentally by an external force, causing an accidental ejection of the pull handle 1. Therefore, an improvement in this rega

This invention relates to a method of making an abrasive article and in particular to a method of making an abrasive article comprising an abrasive disc of non-woven fibres having a central shaft and a hub securing the shaft to the abrasivedisc.BACKGROUND Abrasive discs for polishing and abrading applications are known. Generally such discs are releasably attached to a rotatable chuck, backup pad or shaft of a machine. There are a variety of means for attaching abrasive discs to a machine. Polishing discs and abrasive discs for light abrading applications may be releasably secured to a back-up pad e.g. by pressure sensitive adhesive, hook and loop fastener etc., and the back-up pad attached to the machine by a central boss or spindle. Another means of attachment comprises providing the disc with a central hub or boss. The hub may have an internal thread for engagement with a threaded shaft mounted on the machine. Alternatively the hub may have a central aperture through which athread shaft mounted on the machine is inserted and secured by a nut. A further means of attachment comprises providing a disc with a central shaft which may be engaged by a rotatable chuck mounted on the machine. JP 11320423A discloses a method of making a polishing disc in which a disc of non-woven fibres having a central aperture is placed in a mould and a boss having a central through aperture is formed by injection moulding a thermoplastic material.

1. Field of the Invention This invention relates to a connecting fitting, and more particularly to a connecting fitting for furniture installation, which is able to be used repeatedly. 2. Description of the Prior Art Connecting fittings can be used for furniture connection. Such techniques have been disclosed, such as U.S. Pat. No. 5,611,637, titled "Furniture Fitting", which comprises at least one dowel 6 to be inserted into a hole 22 in one furniturepart, an expansion member 10 disposed in the dowel 6, and a holding member 8 connected to another furniture part. The expansion member 10 has an expansion surface and is movable relative to the dowel 6 between a relaxed position, enabling the dowel 6 tobe inserted into the hole 22, and an expanded position. The holding member 8 is connected to an end of the expansion member 10 with a shaft for pivotal movement about the shaft. The holding member 8 has a cam surface 9 which is adapted to abut againsta surface of the dowel 6, such that pivotal movement of the holding member 8 causes the cam surface 9 to abut against the surface of the dowel 6, and the holding member 8 drives the expansion member 10 to move axially. With the expansion surface toexpand the dowel 6, the dowel 6 is able to be secured in the hole 22. The dowel 6 is substantially formed with plural teeth around its surface. The inner surface of the hole 22 of the furniture part can be bit by the dowel 6 when the dowel 6 is inserted into the hole 22 and the holding member 8 is turned for theexpansion member 10 to expand the dowel 6. However, once the holding member 8 is released, the expansion member 10 will return to its original position, so that the dowel 6 will be released and the teeth will be disengaged from the inner surface of thehole 22. When the teeth engage with or disengage from the inner surface of the hole 22, it will leave marks at the same positions each time. After many times of usage, the marks will influence the retaining effect

1. Field of the Invention The present invention relates to a double nut for use in fastening two nuts against a bolt in order to fix various kinds of machine devices or iron frames of a building or the like. In particular, it relates to an outside lock nut which isoverlapped on a fastening nut so as to prevent the fastening nut from being loosened. 2. Description of the Prior Art A bolt and a nut for use in fastening component parts to various kinds of machine devices in the prior art or a bolt and a nut used in the case of fixing an iron frame of a building or the like are gradually loosened by vibration or the like ofa fastened member. In view of this fact, there have been various kinds of means widely adopted for preventing looseness of such a nut as above. For example, there is provided a "spring washer," wherein part of the washer is cut and a resilient force is added. Inplace of this spring washer, it is also possible to apply a "toothed washer," wherein projections are embossed on a fastening surface. In addition, it is also possible to apply a "pin member" such as a split pin in which a pin is passed through a nut. The pin member is applied such that common through-pass holes are arranged in a threaded part of a bolt and the nut in their radial direction, and the pin is inserted into these through-pass holes. Further, there is provided a "double-nut." The doublenut is operated such that another looseness preventive nut is overlapped on a fastening nut against a bolt and only the outer nut is further fastened forcedly, using a fastening effect between both the nuts and friction between fastening surfaces. It can be expected that the aforesaid prior art "spring washer" may provide an effect of preventing looseness just after its fastening. However, since its use of longer period causes a resilient force of the spring washer to be decreased and aneffect of preventing looseness to be reduced, this prior art nut had a problem that the nut is not suitable

This invention relates in general to fasteners for securing first and second components together. In particular, this invention relates to an improved structure for such a fastener that can be used to both initially drill a hole through firstand second components, then subsequently secure the first and second components together after drilling. This invention also relates to a method of using such a fastener to secure the first and second components together. In the construction of many structures, it is often necessary to secure first and second components together. For example, in conventional post frame construction techniques, which are often used in building a deck or similar structure, it isoften necessary to support a horizontally extending beam on a vertically extending post. To accomplish this, it is known to initially support the beam on the post in a desired orientation relative thereto and to temporarily retain the beam and the postin this desired relative orientation. This temporary retainment is often accomplished by simply manually holding the first and second components in the desired relative orientation or by driving a nail through the beam and post while they are maintainedin the desired relative orientation. Then, once the beam and the post have been temporarily retained in the desired relative orientation, aligned holes are formed through the beam and the post, such as by using a conventional drill. Following theformation of the aligned holes, the drill is withdrawn, and a permanent fastener, such as a threaded carriage bolt, is inserted therethrough. Lastly, a nut is threaded onto the end of the threaded carriage bolt to permanently retain the beam and thepost in the desired relative orientation. Although this method of construction has been effective, it has been found to be relatively time consuming and labor intensive. This is because the tool that is used to form the aligned holes through the first and second components must berem

Field of the Invention The present invention relates, in general, to needle-shaped bristles and methods of manufacturing the needle-shaped bristles and, more particularly, to a needle-shaped bristle, an end of which is tapered, and the other end of which is ground,and a method of manufacturing the needle-shaped bristle. 2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98 Generally, a needle-shaped bristle is a bristle that is gradually reduced in diameter towards one end. Such a needle-shaped bristle exhibits superior ability to penetrate into gaps between teeth or between teeth and gums, and is soft. Thus,recently, needle-shaped bristles are used in most high-grade toothbrushes. However, in the case of the needle-shaped bristle, because the end thereof is too soft, the cleaning ability is insufficient compared to a typical bristle. As an example of an attempt to overcome the above disadvantage, there has been a methodproposed and used in which a bristle, only one end of which is tapered, is folded in half and set in a head part of a toothbrush such that a tapered end thereof is longer than an untapered end, as shown in FIG. 1. Several techniques related to this wereproposed in Japan Utility Model No. Sho. 61-10495 and Korean Patent Registration No. 0464634, which was filed by the inventor of the present invention. These techniques can mitigate the disadvantages of the needle-shaped bristle, but, because the edge of the cut end, which is not tapered, is sharp, it may injure the gums of a user. In an effort to overcome the above-mentioned problem, amethod, in which the end of a bristle is tapered through a chemical treatme

Device Having A Torque-limiting Unit - Patent 8136607

Patents-281 — Sun, 15 Apr 2012 12:39:35 GMT

shared by: Patents-281 on: Sunday, April 15, 2012

The invention is based on a device having a torque-limiting unit. Furnishing a device with a torque-limiting unit in a power drill has already been proposed. Such torque-limiting units are integrated into very powerful power drills embodied as jackhammers and are embodied as a safety overlock coupling, whichis intended to prevent the power drill from sliding away from a user in the hammer drilling mode of the power drill, for instance if a drilling tool suddenly seizes, and the user must suddenly withstand the torque generated by the power drill. As aresult, potential risks to the user can be eliminated.SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a device having a torque-limiting unit in a power drill, which eliminates the disadvantages of the prior art. In accordance with the present invention, it is proposed that the torque-limiting unit is intended to limit a screwdriving torque, or moment, in a screwdriving function. As a result, advantageously, damage to a workpiece and/or a screw, whichis being inserted with the power drill in the screwdriving function, can be avoided. It can be attained that even especially powerful powerdrills can be equipped with a screwdriving function. For instance, a screwdriving function can be integrated with a powerful drilling hammer, so that it is possible to drill a dowel holewith a hammer drilling function and subsequently screw in a screw with a screwdriving function, without having to change to a different power tool. Moreover, screwdriving with a defined tightening moment can be made possible, making a fixedly specifiedpenetration depth attainable. The term "intended" should be understood in this context also to mean "designed" and "equipped". As the power drill, hammer drilling tools, drill hammers, and chisel hammers can for instance be considered. In one feature of the invention, it is proposed that it has an adjustable limiting torque, or moment. As a result, a torque-limit

This invention relates to the field of devices used to drive fasteners into work-pieces and particularly to a device for impacting fasteners into work-pieces.BACKGROUND Fasteners such as nails and staples are commonly used in projects ranging from crafts to building construction. While manually driving such fasteners into a work-piece is effective, a user may quickly become fatigued when involved in projectsrequiring a large number of fasteners and/or large fasteners. Moreover, proper driving of larger fasteners into a work-piece frequently requires more than a single impact from a manual tool. In response to the shortcomings of manual driving tools, power-assisted devices for driving fasteners into wood have been developed. Contractors and homeowners commonly use such devices for driving fasteners ranging from brad nails used insmall projects to common nails which are used in framing and other construction projects. Compressed air has been traditionally used to provide power for the power-assisted devices. Specifically, a source of compressed air is used to actuate a cylinderwhich impacts a nail into the work-piece. Such systems, however, require an air compressor, increasing the cost of the system and limiting the portability of the system. Additionally, the air-lines used to connect a device to the air compressor hindermovement and can be quite cumbersome and dangerous in applications such as roofing. Fuel cells have also been developed for use as a source of power for power-assisted devices. The fuel cell is generally provided in the form of a cylinder which is removably attached to the device. In operation, fuel from the cylinder is mixedwith air and ignited. The subsequent expansion of gases is used to push the cylinder and thus impact a fastener into a work-piece. These systems are relatively complicated as both electrical systems and fuel systems are required to produce theexpansion of gases. Additionally, the fuel cartridges are typically singl

Torque Wrench For Implantable Medical Devices - Patent 8136431

Patents-282 — Sun, 15 Apr 2012 12:28:28 GMT

shared by: Patents-282 on: Sunday, April 15, 2012

The present disclosure relates generally to wrenches, and, more particularly, to torque wrenches used to rotate a connector in an implantable medical device.BACKGROUND Many implantable medical devices such as pacemakers, defibrillators and neural stimulators can sense various physiological parameters through medical leads and/or deliver therapy to tissue. Leads include an elongated flexible lead body. Thelead body comprises one or more insulated elongated conductors with one or more electrodes disposed at a distal end of the conductors. To ensure the lead is properly secured to an implantable medical device, the proximal end of the conductor, referred to as a terminal pin, is passed through a conductor bore in the connector block of a header. A setscrew, which passes through athreaded setscrew bore that intersects with the lead bore, is positioned to contact the conductor. A very small surgical torque wrench is then used to apply a certain amount of torque to the setscrew. Torque applied to the setscrew should provide aretention force between the setscrew and the conductor that is sufficiently large to prevent the conductor from dislodging from the header yet low enough to prevent the torque from damaging the setscrew or conductor. After the setscrew has beentightened, the torque wrench is typically discarded to ensure contaminants from one surgical procedure are not transferred to another procedure. It is desirable to develop surgical torque wrenches that apply appropriate torque to a setscrew whensecuring a lead to a header and that are also inexpensive in order to reduce the cost of such procedures to patients. BRIEF DESCRIPTION OF THE DRAWINGS The following description of the preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. For purposes of clarity, the same or similar reference numbers are used in thedrawings to identify similar elements. FIG. 1 illustrates an exemplary impla

shared by: Patents-282 on: Sunday, April 15, 2012

1. Field of the Invention The present invention relates to a monkey wrench, and more particularly to a reversible monkey wrench. 2. Description of the Prior Art Monkey wrenches are one of the most common types of hand tools. Some of them are designed to be reversible, in which they can drive a nut in one direction and run idle in the reverse direction, so that they would not have to disengage from thenut after every turning stroke. Some reversible monkey wrenches are provided with slidable jaws that move away from the fixed jaw when they are reversely turned, such as disclosed in U.S. Pat. No. 1,391,251, U.S. Pat. No. 2,562,060, U.S. Pat. No. 2,733,626, U.S. Pat. No. 2,970,502, U.S. Pat. No. 5,809,404 and U.S. Pat. No. 7,137,321. These patents mainly disclose a monkey wrench with a worm gear being slidable, along with its axial rod, in a receiving slot of a head, and thereby a slidable jaw thereof can moveaway from a fixed jaw. Some other patents such as U.S. Pat. No. 3,312,129, U.S. Pat. No. 5,746,099 and U.S. Pat. No. 6,679,139 disclose similar design except that their worm gears are slidable along the axial rods. The heads of the abovementioned wrenches are, however, wider than usual. In addition, most of the above mentioned wrenches use resilient members to push either the worm gears or the axial rods to their original position. Accordingly, how to dispose the resilient member, in order to minimize the size of the head, isyet another topic of the present invention.SUMMARY OF THE INVENTION The main object of the present invention is to provide a reversible monkey wrench whose head is smoothly rotatable with respect to the handle. Another main object of the present invention is to provide a reversible monkey wrench with smaller size. To achieve the above and other objects, a reversible monkey wrench of the present invention includes a handle, a head, a slidable jaw, an axial rod and a worm gear. The handle has a connecting end for the hea

Patents-282 — Sun, 15 Apr 2012 12:26:15 GMT

shared by: Patents-282 on: Sunday, April 15, 2012

BACKGROUND Fasteners such as bolts and nuts may tend to back or reverse out over time due to temperature changes, vibration, rotation, etc. In addition, fasteners may be tampered with by people attempting to unhook or open an item having fasteners. Insome of these situations, it is helpful to have a fastener that cannot back or reverse out. Castle nuts are one type of nut that resists backing out. The castle nuts have slots that engage a cotter pin inserted through a bolt so that the nut cannotrotate on the bolt. Other nuts may have threads that use a plastic O-ring to create an interference fit with a bolt and prevent reversing out. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 illustrates a non-reversible fastener apparatus according to certain teachings of the present disclosure. FIG. 2A illustrates a bolt of the non-reversible fastener of FIG. 1. FIGS. 2B-2C schematically illustrate techniques for producing locking grooves in the bolt of FIG. 2A. FIGS. 3A-3B illustrate plan views of a locking nut and a releasing tool of a first non-reversible fastener apparatus. FIGS. 4A-4B illustrate plan views of a locking nut and a releasing tool of a second non-reversible fastener apparatus. FIGS. 5A-5D illustrate various views of a locking nut and a releasing tool of a third non-reversible fastener apparatus. FIG. 6A-6B illustrate plan views of a locking nut and a releasing tool of a fourth non-reversible fastener apparatus. FIGS. 7A-7F illustrate plan views of various arrangements of locking nuts and releasing tools. FIG. 8 illustrates another arrangement of a locking nut and a releasing tool. FIGS. 9A-9C illustrate plan views of locking nuts having a hexagonal shape and one or more locking teeth. FIGS. 10A-10E illustrate various releasing tools for the locking nuts of FIGS. 9A-9C.

Wrenches - Patent 8136427

Patents-282 — Sun, 15 Apr 2012 12:26:03 GMT

shared by: Patents-282 on: Sunday, April 15, 2012

The invention relates to hand tools that can be used in a variety of projects. Specifically, the invention relates to wrenches having two heads that are useful for repairing many different types of objects. The objects include motorcycles,automobiles, small engines, and appliances. These wrenches may also have utility in home repair and improvement.BACKGROUND OF THE INVENTION Combination wrenches, or those wrenches that have more than one working component are known in the tool art. Wrenches of these types can have two wrench heads, or a wrench head and another tool component. For example, U.S. Pat. No. 7,143,669is a combination of a wrench and a drive member. U.S. Pat. No. 7,093,519 discloses a three-in-one wrench that has a structured ratchet wrench in the center of the wrench body, a socket wrench with opening jaws on one end of the wrench body, and anadjustable mortise-tenon pivotal wrench on the other end. U.S. Pat. No. 6,886,430 is a third combination ratchet and breaker bar wrench. U.S. Pat. No. 6,286,398 is also a combination wrench. Here the wrench heads will pivot if required. Yetanother combination wrench is disclosed in U.S. Pat. No. 5,823,077, which teaches a wrench with two heads and a slidable handle. All of these wrenches, however, are fixed together and do not separate into individual components. According to other conventional designs, different wrenches, socket wrenches, ratchet socket wrenches, or reversible ratchet socket wrenches may be used for turning different sizes of bolts and nuts, or other fastening pairs. Further, forturning bolts and nuts of different sizes, a socket wrench must be used of a full set of hexagon head sockets. When carrying socket wrench and a fill set of hexagon head sockets, a special tool box or the like must be used. It is expensive to prepare aspecial toolbox, different hand tools and tool accessories. It would be an advantage to provide a hand tool that has two wrench heads, each situated a

1. Field of the Invention This invention relates to a hinge arrangement of a door for shooting an opening such as a housing opening, partition opening, wall opening, or the like, having at least one pivot pin that is connected to the door, that points vertically towardthe housing, and can be brought into engagement in a pivot pin receptacle in the housing. By sliding vertically, the pivot pin can be moved from a retracted position in which the pivot pin is not engaged in the pivot pin receptacle into an extendedposition in which the pivot pin is engaged and rotatably supported in the pivot pin receptacle. 2. Discussion of Related Art German Patent Reference DE 10 2007 012 980.9 discloses a door arrangement in which the attachment side, such as the hinge side, can be switched in order to permit the door to open toward a different side. To permit the door to first be attachedat will, first at the left and then at the right, the door is embodied with two attachment sides. In this case, each attachment side has a hinge, which through corresponding actuation of an actuating lever, can be brought into one position to form ahinge and into another position to form a latch. When functioning as a hinge, a pair of one pivot pin pointing vertically upward and one pivot pin pointing vertically downward engages in corresponding pivot pin receptacles in the housing. If the hinge or latch on an attachment side is to beopened, then through corresponding actuation of the actuating lever, the two pivot pins on the corresponding attachment side are retracted from the associated pivot pin receptacles so that the door can be opened on the attachment side. The hinge on theother attachment side remains closed in this case. If the door is open on one side and the actuating lever is actuated again in order to open the other attachment as well, this can lead to an unintended unhinging of the door, which can result in damage to the door if it is not held firmly. On the other hand, prob

I. BACKGROUND A handle which provides a shaft coaxially rotatably engaged to a first bearing element and a second bearing element which attaches to a corresponding one of the opposed ends of a cable means. Rope jumping also referred to as rope skipping, skip roping, and jump rope is a skilled activity. There are literally thousands of jump rope skills which rope jumpers strive to achieve at increasingly greater jump rope spin or turn rates. While conventional jump ropes have improved over time, substantial problems with conventional jump ropes still remain unresolved. A first substantial problem with conventional jump ropes may be that the constructional form of the jump rope handles limits the rate at which the attached rope or cable element of the jump rope can be spun or turned. One aspect of this problemmay be the level of resistance to rotation of the rope or cable element by conventional jump rope handles. The greater the level of resistance to rotation of the cable within the jump rope handle the lower the rate of turn or spin achievable by ajumper. A second aspect of this problem may be that the rope or cable element attaches too closely or too far from the jump rope handle. Attachment of the rope or cable element too close to the handle may result in contact between the cable element andthe handle during turns of the rope or cable element. Attachment of the rope or cable element to far from the jump rope handle establishes the length of the lever arm through which the forces developed as the jump rope spins or turns are directed to thejump rope handles. As the lever arm increases in length, the difficulty in controlling the motion correspondingly generated in the handles can increase to an extent that the rate at which the rope or cable element turns can not be increased. A thirdaspect of this problem can be that attachment of the cable to the handle does not allow the cable to swivel on the cable axis or allow the cable to pivot relative to the han

The present invention relates to a door hinge for openably and closably attaching a vehicle door to a vehicle body, in particular, to a door hinge for a vehicle, having a check function, that is provided with a function to maintain the openingdegree of the door. Priority is claimed on Japanese Patent Application No. 2006-311529 and Japanese Patent Application No. 2007-114045, the contents of which are incorporated herein by reference.BACKGROUND ART In general, a door of a vehicle is openably and closably attached to a vehicle body via a door hinge, and is configured so that when the door is opened to a set opening degree, a retention resistance is received by a door checker providedbetween the vehicle body and the door. However, in such a door attachment structure, there is a need for providing the door checker separately from the door hinge, and therefore the number of components increases. Consequently, there has been developed a door hinge that is providedwith a function to retain the door opening degree at a set position (door hinge having a check function). In a conventional door hinge having a check function, a vehicle body-side hinge member and a door-side hinge member are relatively rotatably connected by a hinge shaft, and there is provided a check resistance application device that increasesrotational resistance when both of the hinge members have rotated up to a set angle (for example, refer to Patent Documents 1 and 2). Specifically, for example, an engagement roller that is spring biased in the radial direction is arranged on the outer circumferential side of the hinge shaft, and an engagement groove is formed in a set angle position on the outercircumferential surface of the hinge shaft. When the vehicle body-side hinge member and the door-side hinge member have rotated up to the set angle, the engagement roller engages with the above engagement groove, to thereby increase rotationalresistance.

1. Field of the Invention The present invention relates to a sports tower spinner and, more specifically, to a banner spinner handle used by sports fans and other fanatics to show spirit. 2. Description of the Related Art Sports team's fanatics wave towels and banners in many venues to show support and to rally team momentum. Oftentimes, a sponsored towel is given to every fan at a ticket gate so that they can be waved in unison during a game. The towel is spunat the fingertips by a rotation of the fan's wrist during crucial plays. The towel-banners provide a unique visual effect on viewers when a number of them are spun simultaneously. The towels, acting as banners, have become novelties similar to fans, pom-poms and inflatable hands. A need is therefore felt to relieve fan's wrists of the strain caused by spinning and therefor allowing extended or more vigorous use. Thepresent invention teaches a spinner handle that provides a fanatic with a means to spin the towel-banner in his or her palm as opposed to the fingertips.SUMMARY OF THE INVENTION It is an object of the present invention to teach a spinner handle for a sport's fan banner. It is an object that the present invention removably grasp a towel or a banner so that it can be spun to show spirit. It is an object that the spinnerhandle provide the fan with a more comfortable ergonomic grasp so that he or she is less strained when spinning the banner-towel. It is envisioned that a handle comprise either an upper head with a neck that is received in an aperture on a separate attachment body. The attachment body comprises two parts that fold onto one another to clamp the banner-towel at a corner. Amovement of the person's wrist causes the aperture to spin about the neck, thus causing the banner-towel clamped in the attachment body to spin too. In using the present invention a sports fan towel is prevented from wrapping around one's wrist, as it typically becomes entangled because of its inability to sp

The disclosure relates generally to pivot pins for swinging doors and specifically to pivot pins for swinging pet doors.BACKGROUND OF THE INVENTION Pets are an integral part of many families. Dogs and cats are by far the most popular types of pets. Dogs and cats, like all animals, occasionally require access to the outdoors for exercise or to perform other biological functions. Traditionally, owners of pets opened a full size door each time the pet wanted to go outdoors and walked the pet on a leash. Eventually, some owners began fencing a portion of land so that the pet would be free to run within a confined space. Someowners found it convenient to leave the pet in the fenced in portion for most of the day, thereby avoiding repeated opening and closing of the outside door. However, in most climates, temperature variations from day to day could present a hazardoussituation for a pet left outdoors. In order to provide as much freedom as possible while still allowing the pet access into the regulated environment of the home, some pet owners installed small "doggy doors," which the pet could open and close on their own. Most of the early"doggy doors" were simply openings in a wall covered with a flexible material that would give way when the pet passed through the opening. While accomplishing the function of giving the pet access in and out of the home, these early "doggy doors" didnot seal well and thus were very energy inefficient. One solution to this problem was mounting a solid swinging door in the opening. Such a door is shown in FIG. 1. The door 10 includes a frame 12 surrounding an opening 14 in a wall of a home. One ormore panels 16 are pivotably mounted within the frame 12. The panels 16 may swing in one or both directions and the panels 16 may be biased to a closed position by one or more springs (not shown). The solid panels provide better insulation and a moreaesthetically pleasing appearance than the former flexible material doors. Tradition

The present invention relates generally to appliance supports, and more particularly to a leveling leg and wheel assembly for an appliance such as a free standing range. Ranges, and other such appliances, can be large and bulky. The size and weight of larger ranges can, in some cases, be approximately 600 lbs. This can make it difficult to move and manipulate such a range, particularly after the range ispositioned within its space. It would be advantageous to be able to easily move and level the range. While certain adjustment systems exist for rolling and adjusting the height of a range, in many cases the adjustment system is exposed to view. Sincethe looks and appearances of ranges are also important, it would be advantageous to be able to hide such adjustment systems from view when they are not being adjusted. Moreover, once a range is moved into an installation space, such as a cabinet, it can also be difficult to access the legs or associated height and leveling devices, particularly with respect to the rear legs of the range. It would beadvantageous to be able to roll a range into place without the use of other tools or dolleys, and easily access all height and leveling devices in order to level the range at each corner.BRIEF DESCRIPTION OF THE INVENTION As described herein, the exemplary embodiments overcome one or more of the above or other disadvantages known in the art. One aspect of the exemplary embodiments relates to a leveling leg and wheel assembly for an appliance. The leveling leg and wheel assembly includes a first member having a first end attached to the appliance, and a second end opposite to thefirst end; a second member, one of the first member and the second member being slidably disposed in the other of the first member and the second member; a roller fixedly disposed relative to the first member and extending downward beyond the second end;a threaded sleeve fixedly disposed relative to the first member; and a leveling leg having an

S NoneFEDERALLY SPONSORED RESEARCH OR DEVELOPMENT NonePARTIES TO A JOINT RESEARCH AGREEMENT NoneREFERENCE TO A SEQUENCE LISTING NoneBACKGROUND OF THE INVENTION 1. Technical Field of the Invention The present invention relates generally to a combination pipe cutter and can lid opener, and method of use thereof, and more specifically to a combination pipe cutter and can lid opener that provides a means for cutting pipe and a means foropening and/or gripping the lid of a can, or the like. 2. Description of Related Art A variety of tools are utilized by carpenters and construction workers to cut pipes and/or open containers. As a result, workers often carry multiple tools. However, transporting multiple tools is cumbersome because it requires a worker tocarry several tools around while working. As such, multi-functional tools are beneficial because workers can accomplish tasks while minimizing the burden of carrying multiple tools. However, multi-functional tools do not typically have the ability toallow a worker to open containers. To relieve the difficulty of transporting multiple tools, one previous device teaches a combinational tool having a first blade and a second blade pivoted in the middle. Notches are respectively made on the first and second blades forming asocket wrench. While this device is suitable for stripping and/or crimping wires, it is not suitable for gripping and subsequently opening glue containers. Another device comprises a wrench, wherein the wrench has a first and second handle with internal jaws at the proximate end of the handle section. While this device allows a user to unscrew bolts, the device does not have a gripping mechanismwithin the handles of the wrench to open containers. Therefore, it is readily apparent that there is a need for an apparatus that allows a user to both cut materials and open containers, wherein the user opens containers via a gripping mechanism along the inside of the handles of the apparatus.BRIEF SUMMARY

S The present application claims priority under 35 USC 119 to German Patent Application No. 10 2009 015 376.4 filed on Mar. 27, 2009 the entire contents of which are hereby incorporated by reference.FIELD OF THE INVENTION The invention relates to a screw connection for a fixed connection of two assemblies which are mounted in a variable position with respect to each other, using a connecting member penetrated by a screw.DESCRIPTION OF BACKGROUND ART Making a fixed connection of two assemblies is frequently encountered, in particular in the area of the production of furniture where furniture parts, in particular those which meet each other at right angels, are to be brought into engagementwith each other, wherein a fixed connection is established by means of screws. Therein, the problem is frequently encountered that, because of inaccuracies during production, the respective receiving portions for screws, i.e. a hole for a screw head anda bore for a screw thread, are positioned not coaxially to each other such that is necessary to provide for a possibility for correction. In most cases, this is achieved wherein a seat serving for receiving a connecting screw, for a head of a screw isembraced with clearance whereby a corresponding possibility for correction is given for a connecting member connecting two furniture parts (here DE Utility Model G 88 10 628.4, page 3, first paragraph). However, such a possibility for correction proves to be unfeasible when the two parts to be connected to each other, are subjected to vibrations during use such that they tend to be displaced with respect to each other which results in that therespective fastening means can migrate backwards and forwards in the enlarged receiving hole. Such a possibility of correction is unfeasible for many purposes, in particular in automobile construction where particular assemblies are to be fixedseparately to the car body wherein production in accuracies have to be accepted for the car body as well

shared by: Patents-276 on: Sunday, April 15, 2012

BACKGROUND The present indention pertains to cleaning appliances. More particularly, the present invention pertains to household cleaning appliances. Even more particularly, the present invention pertains to sponges having both an abrasive and a spongeportion. As is known to those skilled in the art to which the present invention pertains, sponges and similar appliances are used for cleaning countertops, sinks, bowls, cars, etc. in just about every type of environment, be it industrial or domestic,household. Typically, a sponge is a foraminous material, whether natural or synthetic. Recently, there has been developed, sold and marketed a unitary cleaning product having both a sponge portion and an abrasive portion. As is to be readily appreciated one of the problems encountered with this type of product is the inability to effectively reach into corners as well as along edges for effective scrubbing and cleaning. The prior art has revealed products but none of which are susceptible for effectively cleaning an edge or a corner. See, for example, U.S. Pat. Nos. 1,966,101, issued Jul. 10, 1934 to Miller; 3,611,469, issued Oct. 12, 1971 to Belli;3,861,993, issued Jan. 24, 1975 to Guthrie; and U.S. Design Pat. No. D473,027, issued Apr. 8, 2003 to Pecaut. As will subsequently be detailed the present invention overcomes the problems in the prior art by providing a sponge product which provides both a foraminous portion as well as an abrasive portion and which can readily reach into corners andedges.SUMMARY In accordance herewith there is provided a multi-surface sponge product, which has a foraminous portion and an abrasive portion, which are specially configured and joined to one another to form a unitary assembly in the form of a unitized handgrippable block or body, which in side elevation or cross-section is in the form of a parallelogram. The foraminous and abrasive portions are in the form of parallel layers and each portion has opposite sidewalls and a

shared by: Patents-282 on: Sunday, April 15, 2012

This invention relates to a power screw gun with a hammerhead and more particularly to a pneumatic power screw gun with a reinforced hammer head.BACKGROUND OF THE INVENTION In a process of using a powered screw gun, it becomes necessary to strike the screw at times and finish setting the screw in the desired surface. To that end, a worker will commonly use the base end of the powered screw gun to set a screw. Apowered screw gun is not designed for such use as a hammer. When a powered screw gun is used as a hammer, the screw gun must suffer some damage. The damage may cause either damage on the external casing or internal powered source of the screw gun. Clearly, such damage can adversely affect the screwgun. Thus, there is an advantage in minimizing damage to the powered screw gun.SUMMARY OF THE INVENTION Among the many objectives of the present invention is the provision of a pneumatic power screw gun with a reinforced hammer head. Another objective of the present invention is the provision of a pneumatic power screw gun with a replaceable hammer head. Yet another objective of the present invention is the provision of a pneumatic power screw gun with a reinforced mounting for a hammer head. These and other objectives of the invention (which other objectives become clear by consideration of the specification, claims and drawings as a whole) are met by providing a pneumatic power screw gun with a reinforced hammer head, having areinforced base end with a stamped cradle mounted thereon, the stamped cradle being adapted to receive a hammer head.

Patents-279 — Sun, 15 Apr 2012 05:20:49 GMT

shared by: Patents-279 on: Sunday, April 15, 2012

This invention relates to a balance system for use in a pivotable, sliding window assembly of a sash window, and more particularly to a block and tackle balance assembly with a rotatable shoe.BACKGROUND OF THE INVENTION A sash window is comprised of one or more moveable panels or sashes, where each sash forms a frame that may hold multiple panes of glass, and both sashes are themselves mounted into a window frame. A "single hung" sash window ordinarily opensby having one sash member, typically the lower sash, sliding vertically relative to the window frame. An arrangement where both sash members can slide vertically is termed a "double hung sash window" or double hung window. For applications in buildingswith tall openings, such as for church windows, triple and quadruple-hung windows have been utilized to accommodate the opening. Each sash member, being comprised of multiple panes of glass housed in a wood frame of the sash, would be quite heavy for most homeowners to open or close with relative ease. Such sash members have traditionally been fitted with a means ofcounterbalancing the weight of the window panes and frame of the sash member, where such balancing means even permits small children to raise and lower the heavy sash member. Although advances in the materials used for the construction of sash frames,beyond the use of wood, may have lead to reductions in the final weight of the sash members, any reductions have been largely been offset by the use of the double paned glass arrangement, which was developed to increase thermal efficiency. The means of counterbalancing the sliding sash windows, in its early and perhaps simplest form, was just a cord attached at one end to a counter weight, with the cord crossing a pulley and, at the opposite end, attaching directly to the window. The mass of the weight in that arrangement is necessarily calibrated to counter the weight of the sash member and the friction of the pulley. If the counterweight were sized e

Patents-279 — Sun, 15 Apr 2012 05:20:30 GMT

shared by: Patents-279 on: Sunday, April 15, 2012

ON The present invention is directed to interchangeable and customizable pull mechanisms (e.g. knobs and handles) used on barrier structures. Barrier structures are everywhere. Most doors are swinging barrier structures. Some doors, such as sliding glass doors and sliding closet doors are sliding barrier structures. Sometimes the barrier structures are just a face of anotherstructure. For example, the face of a drawer barrier structure that slides because the drawer to which it is attached slides. Barrier structures can have other types of movement such as rotation. Some barrier structures (e.g. walls) are not movable. To facilitate the actuation of the movement of a barrier structure, most barrier structures include a gripping mechanism such as a knob or a handle (herein after referred to generally as a "pull mechanism"). A pull mechanism is fastened to abarrier structure to provide a means for a user to move the barrier structure via the movement of the pull mechanism. For purposes of this specification, the term "knob" will be used to describe a pull mechanism that has a single point of contact withthe barrier structure and the term "handle" will be used to describe a pull mechanism that has multiple points of contact with the barrier structure. It should be noted that a pull mechanism may be used even if it does not facilitate movement. For example, a pull mechanism may be used on an unmovable barrier structure. The use of such a pull mechanism may be decorative or may serve anotherfunction (e.g. for use as a hook for hanging objects). The proliferation of barrier structures generally tends to result in a proliferation of pull mechanisms. Cabinets, doors, furniture, and other fixtures often have pull mechanisms that are commonly used or purchased through commercial outlets. The manufacturer of these'fixtures may choose among a wide variety of commercially produced pull mechanisms. These pull mechanisms can affect the appearance, style, and feel of th

Snap Hinge For Furniture - Patent 8132294

Patents-279 — Sun, 15 Apr 2012 05:20:22 GMT

shared by: Patents-279 on: Sunday, April 15, 2012

The present invention refers to a snap hinge for furniture. In particular the invention relates to a snap hinge for rotating and supporting a closing element of a cabinet. Snap hinges are known in the furnishing industry for imposing on furniture-closing elements an elastic forcing condition. It is in fact known that in a closed position it is often desirable to maintain the closing element firmly in contact with the furniture. It is also known that in an open position, in particular in the case of elements closing wall cabinets rotatingly upwards, the hinges have to exert a relatively great force to support the weight of the closing element and maintain the closingelement raised. These forces obtained by means of generally soft elastic elements are even greater in the case of closing elements for closing furniture for campers, caravans or the like inasmuch as the dynamic situation to which the closing element issubjected in both the closed or open positions requires greater force and resistance of the hinge and of the elastic elements. Known snap hinges comprise a first and a second articulated quadrilateral that have in common a first and a second lever and which have as a base element respectively a first fixing bracket for fixing to a fixed element of a piece of furnitureor the like and a second fixing bracket for fixing to a closing element. Recent known prior-art snap hinges further comprise at least two springs arranged in a kinematic chain between the two articulated quadrilaterals. Each of the two articulated quadrilaterals consists of the first and the second lever, of an arm and of a base element, respectively one of the fixing plates, which are articulated amongst one another. In particular, the hinge is made so thatin the opening configuration the spring of the snap hinge operates in opposition to the weight force of the door and thus has a function of supporting the door. In the closing configuration the elastic action exerted by the spring is suita

Portable Computer Clutch Structures - Patent 8132293

Patents-279 — Sun, 15 Apr 2012 05:20:12 GMT

shared by: Patents-279 on: Sunday, April 15, 2012

BACKGROUND This invention relates to electronic devices and, more particularly, to clutch structures for hinges in electronic devices such as portable computers. Portable computers typically have upper and lower housing portions that are connected by a hinge. The lower housing portion contains components such as printed circuit boards, disk drives, a keyboard, and a battery. The upper housing portioncontains a display. When the computer is in an open configuration, the upper housing portion is vertical and the display is visible to the user of the portable computer. When the computer is closed, the upper housing lies flat against the lowerhousing. This protects the display and keyboard and allows the portable computer to be transported. Portable computer hinges are challenging to design. It is generally desirable to make a hinge easy to manipulate. A hinge with an overly stiff clutch mechanism may require a user of the computer to use undesirably large amounts of force to pryopen the display when using the computer. Stiff hinge clutches may resist opening to such an extent that the entire base of the computer will be lifted upwards if a user attempts to open a display using only one hand. To address these concerns,clutches may be made that are less stiff. Although clutches such as these may be more pleasing to use, they may not always prevent unintended movement of the upper housing relative to the main housing. It would therefore be desirable to be able to provide improved clutch structures for hinges in electronic devices such as portable computers.SUMMARY A portable computer with improved hinge clutch structures is provided. A clutch may be provided that has asymmetric closing and opening forces produced by friction band members of different sizes. A protective cap may be formed over the tip ofthe clutch to prevent damage to nearby wires. A slotted tip may be provided on a clutch shaft to engage a clutch spring. A lobe may be formed in the spring in

CROSS-REFERENCE TO RELATEDAPPLICATION This application is a 35 USC 371 application of PCT/EP 2007/057148 filed Jul. 12, 2007.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention is based on an auxiliary handle device. 2. Description of the Prior Art The invention is based on an auxiliary handle device, in particular for hand-held power tools, with an attaching device that has at least one fastening mechanism.SUMMARY OF THE INVENTION The invention is based on an auxiliary handle device, in particular for hand-held power tools, with an attaching device that has at least one fastening means. According to one proposal, the fastening mechanism is provided for producing a form-locked connection in an axial direction of a fastening axis, thus achieving an efficient securing of an auxiliary handle in the axial direction. Thisadvantageously prevents the auxiliary handle from slipping in the axial direction, for example in the event that a tool jams during operation of the hand-held power tool. The auxiliary handle device is particularly provided for the fastening of theauxiliary handle to a hand-held power tool such as a drilling and/or hammering hand-held power tool, e.g. an impact drill, so that the fastening axis of the fastening device corresponds to a tool axis of the hand-held power tool, in particular a drillingaxis. In this context, an "axial direction of a fastening axis" is understood to be a direction along the fastening axis. According to another proposal, the fastening device has at least one additional fastening mechanism for producing a form-locked connection in a circumference direction of the fastening axis, thus making it possible, in addition to a securing ofan auxiliary handle to a hand-held power tool in the axial direction of the fastening axis, to also achieve a securing of the auxiliary handle in the circumference direction of the fastening axis. The fastening mechanism for producing the form-lockedconnection in the circumference

Field of the Invention This invention relates to a hinge device and, more particularly, to a hinge device having a spherical joint. 2. Description of the Related Art With continuous improvement of information technology, various kinds of electronic devices, such as personal digital assistants (PDAs), tablet PCs, digital cameras, global positioning system (GPS) devices and so on, come out one after another. The electronic devices can further be connected with hinge devices according to needs in use. For example, the hinge device in a car can be used for mounting an object such as a GPS device or a PDA to facilitate watch and operation by users. Furthermore, the object, such as a digital camera, a tablet PC and so on, can also be mounted to the hinge device to facilitate operation. Generally speaking, the object mounted to the hinge device can be rotated relative to the hinge device, such that the users can adjust the device to an angle at which the object is convenient for operation or watch. The object mounted to thehinge device can be rotated relative to the hinge device via a uniaxial rotatable bracket. However, although a rotatable range of the device can be improved via the combination of more than two uniaxial rotatable brackets, compared with that of a rotatable structure in a spherical joint type, the rotatable range of the device is stilllimited. However, in using the rotatable structure in the spherical joint type, when the users need to adjust an angle of the rotatable structure in the spherical joint type, first they need to release a clamp of the rotatable structure, and then theycan lock the clamp after adjusting to a suitable angle. Thus, each time the adjustment is performed, th

Hinge Mechanism For A Wireless Communication Device - Patent 8132292

Patents-279 — Sun, 15 Apr 2012 05:19:42 GMT

shared by: Patents-279 on: Sunday, April 15, 2012

BACKGROUND The present application relates generally to wireless communication devices having relatively movable housing portions and, more particularly, to a hinge mechanism for connecting the relatively movable housing portions. Wireless communications devices, such as cellular telephones, personal digital assistants, and the like, frequently have two housing portions that are relatively moveable. For example, a common cell phone design is a so-called clamshell design,with a "flip" having a speaker and a display, and a base portion having a keypad and a microphone. The flip portion is connected to a base portion via a hinge. The flip portion rotates via the hinge between a closed position disposed proximate the basesection in an overlying configuration and an open position where the flip and base are aligned end to end, similar to an open clamshell. A variety of hinge mechanisms are available for connecting the two housings portions. Most, if not all hinges, generally include a device that yieldingly resists movement of the housings between the open and closed positions. For example,hinges that pivotably connect the two housings of a cellular telephone may include corresponding detents associated with each of the housings. The detents contact each other as the user pivots the housings between open and closed positions. Thiscontact resists the pivoting motion, but yields when the user applies a proper amount of force. The detents also function to maintain the housings in the open and closed positions. Other hinges may include one or more springs that resist the pivotingmotion of the housings. Once the user applies a proper amount of force, the springs yield to permit the housings to move to the open and closed positions. For clamshell-type phones, the construction of the hinge is an important design consideration to provide mechanical strength and durability while maintaining a size small enough to fit into increasingly smaller housings. Additionally, th

Locking Device For Telescoping Pole And Appliance Provided With Such A Locking Device - Patent 8132289

Patents-279 — Sun, 15 Apr 2012 05:19:01 GMT

shared by: Patents-279 on: Sunday, April 15, 2012

The present invention relates to a locking device for a telescoping pole, or rod, intended in particular to equip a retractable handle system. The invention relates more particularly to a locking device in which the telescoping pole has atleast one moveable section slideably mounted in a guide member having at least one opening intended to receive a locking member carried by a body that is fixed to the moveable section. U.S. Pat. No. 5,581,846 discloses a retractable handle system in which the handle is mounted on telescoping poles, or rods, each having a moveable section slideably mounted in a guide member. In this patent, the moveable section can be lockedat different heights by means of a locking device having a locking member carried by the moveable section and engaging, under the force of a spring, in an opening provided on the telescoping guide member. To permit unlocking of each telescoping pole,there is provided a button that acts, through the intermediary of a rod means, on the locking member in a manner to displace the locking member in opposition to the spring and to disengage it from the opening. Telescoping poles, or rods, of this type have, however, the drawback that they include a moveable section that must be mounted in its guide member with a sufficient play to avoid excessive rubbing between the pole and the guide member, in orderto permit easy actuation of the pole by the user. As a result, there is a poor connection of the telescoping pole at the joint between the movable section and the guide member leading to a warping, or bending, of the telescoping pole when weight isapplied on the handle and provoking possible clicking noises when this handle is subjected to vibrations. French patent number 2 870 693 proposes a solution to these drawbacks by disposing a bearing in the guide member and mounting the moveable section substantially without play in this bearing. However, such a solution requiring use of a bearing presents the drawback of b

In recent years, plastics have been used increasingly in place of glass as a cover or surface of choice for many applications such as watch faces, windows and table surfaces. The advantage of using plastic is that it is more lightweight, lessbrittle, stronger, and far less likely to break than glass. However, one of the drawbacks of using plastic is that its surface is not nearly as hard as glass. Consequently, it is much more prone to being scratched by hard objects or debris, such asmetal, glass, sand, grit, or any other abrasive material. In addition, plastics are more prone to hazing or surface yellowing due to weathering, which is often caused by oxidation or the influence of ultraviolet light from the sun. Such discolorationalso can occur through ordinary cleaning of plastic surfaces. Not surprisingly, while the surface of glass might remain clear for many years, plastic often becomes clouded, yellowed or otherwise opaque through oxidation and by other corrosive forcesfound in nature. Plastic is the material of choice for making motorcycle windshields and airplane or jet windows, all of which must withstand high wind forces and pressure differentials. However, due to such high speed winds, damage to the windshields andwindows is very likely. Within the field of aviation and more particularly, in the area of airplane windows, having clear plastic windows is desirable. Commonly the windows are often scratched, yellowed, or otherwise partially opaque. Besides being merely bothersometo the passenger, such damage can also severely impair the ability of the pilot to see the landscape outside the plane, creating a danger to all aboard. However, the discomfort and negative feeling such window damage can cause to passengers should notbe overlooked. Four airline companies, American Airlines, Delta Airlines, United Airlines and Sky West Airlines, conducted a customer survey and found that the customers' single greatest complaint concerned damage to the planes'

FIELD This invention relates to a fastening apparatus, and, more particularly, to a fastening apparatus that prevents over-tightening and that reduces contamination from stainless steel or other metals.BACKGROUND Parts, such as graphite shields and electrodes, need to be fastened to other components within an ion implanter or other plasma processing tool. Previous methods of fastening have used stainless steel vented shoulder screws or bearing shims. However, stainless steel or other metal fastening devices have two drawbacks. First, when over-tightened, these devices may crack the part being fastened to another component. Second, stainless steel or other metals contaminate the beam or workpiecebeing processed or implanted. Merely covering a stainless steel or other metal fastener with a supplementary graphite shield increases material costs and complexity without addressing the problem of over-tightening parts. Graphite itself is also proneto cracking. If a supplementary shield or graphite fastening device cracks, it may prevent or impede repair or replacement. Accordingly, there is a need in the art for an improved fastening apparatus and, more particularly, a fastening apparatus that prevents over-tightening and that reduces contamination from stainless steel or other metals.SUMMARY According to a first aspect of the invention, a fastening apparatus is provided. The fastening apparatus comprises a graphite body defining a passage through a length of the body; and a threaded member disposed in the passage. According to a second aspect of the invention, a fastening apparatus is provided. The fastening apparatus comprises a body defining a passage through the length of the body, the body having a first region with a first dimension, a second regionwith a second dimension, and a third region between the first region and the second region with a third dimension, the second dimension being smaller than the first dimension, the third dimension being smaller than

The present invention relates generally to the field of devices for attaching objects to a wall and, more particularly, to a wall anchor.BACKGROUND Wall anchors can be grouped together in two general types, namely the expanding anchor type, such as the plug and screw type or the expansion bolt type, and the deploying type such as the toggle bolt type. Anchor of the expanding anchor type are normally easy and economical to manufacture. The plug and screw type is made up of only two elements: a plug and a screw. However, in usage, a predrilled hole much larger than the screw diameter has tobe made. Then a plug is inserted in the hole and, finally, a screw is screwed in the plug, thereby expanding the plug and squeezing the exterior wall of the plug onto the surrounding wall of the hole. While plug and screw type anchors insure a fairgrip between this anchor and walls formed of plasterboard, the dry wall material is far from creating the optimal holding force. Similarly, the expansion bolt type is made of two parts: a bolt and a tube-like over sleeve. The over sleeve has a top section resting on the head of the bolt, while the bottom section has a thread section screwed onto the bottom part of thebolt. The middle section of the over sleeve is made up of bent out metal strips. While this type of anchors still relatively easy to manufacture, it is a little more expensive than the plug and screw type. However, these anchors present manydrawbacks. First, most inexpensive models require a predrilled hole in which they are inserted. Also, in use, after being inserted in the hole, the bolt is screwed, thereby lifting up the bottom part of the over sleeve. The over sleeve squeezesagainst the bolt head causes the metal strips of the middle section to bend outwardly against the surrounding wall of the hole, thereby providing the holding grip. While the expansion bolt type insure a fair grip, it is also far from putting in theoptimal holding force that can be archive

Description of the Prior Art For chemical anchoring of a fastening element such as anchor rod, threaded rod, threaded sleeve, screw anchor, or reinforcement bar in a substrate such as a constructional component or a workpiece, a borehole is produced, cleaned, and filledwith a hardenable compound which advantageously includes multiple components, e.g., a two-component mortar compound. The fastening element is then set in the filled borehole. After the compound hardens, the fastening element has high load values. Unlike mechanically anchored fastening elements, fastening elements of the kind described above are anchored in the substrate without expansion forces so that there is the possibility of small edge distances and axial distances of the anchored fasteningelement in the substrate. Mounting parts are secured to the substrate, for example, by nuts, at the free end of the fastening element anchored in the substrate. EP 0 150 555 A1 discloses a fastening element with a mixing knife that forms a mixing element. The fastening element is introduced into a borehole outfitted with a cartridge. When the fastening element is screwed in, e.g., with a rotarydriving device, the cartridge is destroyed and the components of the hardenable, multi-component compound are mixed together. As was stated, for example, in DE 34 42 383 A1, it was considered essential in technical circles up until now to clean the borehole prior to introducing the hardenable multi-component compound, which represents a substantial expenditure forproducing the attachments, particularly for series applications.SUMMARY OF THE INVENTION It is the object of the present invention to provide a fastening element which can be anchored in a borehole with a hardenable compound and which can be set

Methods, Devices And Systems For Screw Feeding By Vacuum And Gravity - Patent 8127643

1. Field of the Invention The present invention relates generally to screwdrivers, and in particular to methods, devices and systems for feeding screws automatically to an electric screwdriver. 2. Description of the Related Art The typical hard disk drive includes a head disk assembly (HDA) and a printed circuit board assembly (PCBA) attached to a disk drive base of the HDA. The head disk assembly includes at least one magnetic disk, a spindle motor for rotating thedisk, and a head stack assembly (HSA). The spindle motor includes a spindle motor hub that is rotatably attached to the disk drive base. Advances in the hard disk drive industry have led to the incorporation of disk drives into a variety of hand held devices, such as music players, cameras and PDAs. The small size of such devices has led to a corresponding reduction in the formfactor of high capacity hard disk drives. Conversely, the ability of manufacturers to introduce ever smaller drives has led to their incorporation in ever widening classes of electronic devices and to the development of entirely new classes of devices. Form factors have steadily shrunk from 5.25'', 3.5'', 2.5'', 1.8'' and now to 1 inch and smaller drives. As a result of such continuing miniaturization, many of the constituent components of the drives have become too small to be consistently, speedily and reliably handled by human hands. For example, screws that are used in such small form factordrives include so-called M1 screws, which have a diameter of just 1 mm and a head height of just 0.2 mm. These screws are difficult to pick up, couple to a screwdriver and drive into a selected threaded hole in a disk drive. Such problems have led tothe development of electric screw driving machines. Many existing electric screwdrivers in the factory require the operator to manually or vacuum pick the screws from a shaker tray before driving them on designated fixtures. That is, before driving ascrew, the operator must swing the e

Fuse Barrel Component Handling Device - Patent 8127642

Patents-282 — Sat, 14 Apr 2012 20:57:33 GMT

shared by: Patents-282 on: Saturday, April 14, 2012

FIELD OF INVENTION Embodiments of the present invention relate in general to a system for installing and removing a fuse barrel component, and more particularly to a fuse barrel component handling device that engages and supports both load break and non-load breakfuse barrel components.BACKGROUND Fuse barrels are typically positioned in electric circuits. A fuse barrel, which may be suspended from power lines by an upper support member and a lower support member, may include various types of components, e.g., a load break cutout,non-load break cutout, load break sectionalizer, and non-load break sectionalizer. A fuse barrel also may include an insulated fuse tube and a fuse link that allows current to flow through the barrel. When currents of normal levels are flowing throughthe electric circuit, the fuse link will be unaffected and the fuse barrel will remain in a cutout configuration. However, when a fault or an over-current occurs in the circuit, the fuse link will react, causing an interruption of the current in thecircuit. As a result of the reaction of the fuse link, the "blown" fuse tube will be disengaged from the upper support member and will rotate downward into a "drop down" position, breaking the circuit. In the "drop down" position, the fuse link may besaid to be in the sectionalizer configuration. A number of tools and methods have been developed to remove these old or "blown" fuse barrels and to install new fuse barrels. In one such method, a utility worker may use a hook-shaped tool attached to a "hot stick," or other suitable device,to engage the trunnion of the old fuse barrel. As used herein, a hot stick or "extendo stick" refers to a telescoping probe that extends from about 4-5 feet, for example, to about 35-40 feet, or any other suitable distance based on the particularapplication where the device is being used. These types of devices may allow a utility worker to remove and/or install a fuse barrel located on a distribution electrical

1. Field of the Invention The present invention relates to a portable terminal apparatus such as a folding portable telephone apparatus. 2. Description of the Related Art In portable telephone apparatuses (portable terminal apparatuses), a mouthpiece unit (a first body) has an attachment section (a first hinge arm) including an attachment hole (a first axis hole), inside of which a pair of engaging protrusionsare provided at intervals of 180.degree. along the entire length of the axis. Further, an axis-shaped case (a hinge axis) constituting a hinge has recessed grooves axially provided on an outer circumference thereof. The hinge is fitted to theattachment hole such that the recessed grooves are engaged with the engaging protrusions, allowing the mouthpiece unit (the first body) to be foldably attached to an earpiece unit (a second body) via the hinge (i.e., the case, the hinge axis). Relatedtechnology has been disclosed in, for example, Japanese Patent Application Laid-open No. 2004-84805. In the related-art portable terminal apparatus, the engaging protrusions in the attachment hole (the first axis hole) are formed up to end faces of the attachment section (the first hinge arm). This structure has a problem that, when strongforce such as twisting force acts between the mouthpiece unit (the first body) and the earpiece unit (the second body), the force is concentrated on bases of the engaging protrusions at the end faces of the attachment section (the first hinge arm),causing cracking in the bases and thus easily breaking the attachment section (the first hinge arm). This problem is significant in apparatuses in which large stress is applied to the attachment section (the first hinge arm), for example, in portabletelephone apparatuses used to view a television image by rotating a liquid crystal display (the second body) thereof sideways.SUMMARY OF THE INVENTION It is an object of the present invention to at least partially solve the problems in the conven

Patents-279 — Sat, 14 Apr 2012 20:41:18 GMT

shared by: Patents-279 on: Saturday, April 14, 2012

BACKGROUND 1. Technical Field The present invention relates to a clip that is used to hold a door open during electro-coating and painting of a vehicle. 2. Background Art Vehicles are generally produced on assembly lines where component parts are assembled together. Painted frame body components including body panels, doors and structural components are assembled and then electro-coated and painted as a unit toassure acceptable paint quality. After painting, the doors are disassembled from the vehicle to provide access for the assembly of internal components to the doors, such as windows, window operating mechanisms, door handles, lock mechanisms, interiorsoft trim panels, and the like. The doors are reassembled to the vehicle at a later point on the assembly line. The doors of a vehicle must be held open during electro-coating and painting to assure complete coverage and to avoid damage to the surface coatings. Door checks that are incorporated in the vehicle are not installed prior to theelectro-coating and painting because they are not painted with the vehicle to assure proper operation and avoid paint quality problems. Temporary clips or other tools have been proposed, but may be unacceptable due to various reasons such as theeffectiveness of the tools, cost, or because they unduly complicate the vehicle manufacturing process. The present invention is directed to providing an improved method of holding a vehicle door open and to an improved removable clip that is effective and may be provided at a relatively low cost. Further, installation and removal of the clip donot substantially complicate the vehicle manufacturing process and do not require additional process steps or added labor costs. The above problems and others are addressed by Applicants' invention as summarized below.SUMMARY According to one aspect of this development, a clip is assembled to the hinge pin of a vehicle door that is used to hold the door in the full open position and prevent cl

Attachment For Clutchingly Covering A Major Portion Of A Handle Of A Plunger, Enhancing Grip Of The Handle Of The Plunger, And Absorbing Shock From Repeated Thrusts Of The Plunger - Patent 8127402

shared by: Patents-279 on: Saturday, April 14, 2012

2. BACKGROUND OF THE INVENTION A. Field of the Invention The embodiments of the present invention relate to an attachment for a handle of a plunger, and more particularly, the embodiments of the present invention relate to an attachment for clutchingly covering a major portion of a handle of aplunger, enhancing grip of the handle of the plunger, and absorbing shock from repeated thrusts of the plunger. B. Description of the Prior Art A plunger is a common device that is used to release stoppages in plumbing. The tool consists of a rubber cup with an attached stick. The cup is pushed down against the drain, and either pressed hard into the drain to force air in, or ispushed down until the rubber cup is flattened and then pulled out causing a vacuum. The intent is to loosen or break up a clog, excessive material, or other blockage in the outlet or drainage pipe from a sink, toilet, bathtub, shower, etc. Thedifference between a sink plunger and a toilet plunger is that the former looks like a ball cut in half, while the latter looks more like a distorted ball with a large hole on the bottom. Pressing the cup down hard into the drain until the rubber cup is flattened and then pulling the cup out requires a good grip by both hands of the user on the plunger handle. There is considerable impact on the palm of the user from therepeated thrusts, which causes discomfort to the user's hand. Further, it is difficult to grip the handle of the plunger, which is usually smooth and wet. Thus, there exists a need for an attachment for clutchingly covering a major portion of a handleof a plunger, enhancing grip of the handle of the plunger, and absorbing shock from repeated thrusts of the plunger. Numerous innovations for grips have been provided in the prior art, which will be described below in chronological order to show advancement in the art, and which are incorporated herein by reference thereto. Even though these innovations maybe suitable for the specific individual

shared by: Patents-277 on: Saturday, April 14, 2012

Firefighters often face dangerous, difficult, and unpredictable situations which require the use of manually held firefighting tools. Normally, several different types of tools are required to address the need to manually ventilate spaces, gainentry into burning structures or vehicles, pry or batter down doors, walls, and windows, penetrate locks and gates, rescue individuals, and perform a myriad of other tasks. Various tools are used for these purposes e.g. Halligan bars, pry axes,crowbars, flat bars, pike poles, padlock breakers, and others. However, there are very few practical, useable, handheld firefighter tools which are configured to perform multiple tool functions and none which have the versatility to be used in most toolrelated circumstances a firefighter will encounter.SUMMARY OF THE INVENTION The object of the present invention is to overcome the disadvantages and limitations of prior manually held firefighting tools by providing a single tool which is configured with the most desirable and practical features of existing tools. Thefirefighting tool of the present invention combines the aspects of ceiling hooks, drywall hooks, duckbill padlock breakers, pry bars, battering rams, wall picks, hay drags, rubbish rakes, spikes, baling hooks, clawed tools, and others. The subject toolis a striking, pushing, pulling, and prying tool all in one. Its claw, spike, and adz-like elements provide for new prying configurations, not found in other forcible entry tools. The length of the tool allows for better leverage and can easily beutilized by two firefighters for heavy prying, pulling and battering. Its extreme versatility allows the firefighter to carry a single tool with many functions, as opposed to the need for carrying many different types of tools. These and other objects are accomplished by the invention, a manually held firefighting tool which comprises an elongated staff section having a first working member at one end and a second working member

Method Of Making Abrasive Shards, Shaped Abrasive Particles With An Opening, Or Dish-shaped Abrasive Particles - Patent 8123828

Patents-275 — Sat, 14 Apr 2012 14:47:35 GMT

shared by: Patents-275 on: Saturday, April 14, 2012

BACKGROUND Abrasive particles and abrasive articles made from the abrasive particles are useful for abrading, finishing, or grinding a wide variety of materials and surfaces in the manufacturing of goods. As such, there continues to be a need forimproving the cost, performance, or life of the abrasive particle and/or the abrasive article. Triangular shaped abrasive particles and abrasive articles using the triangular shaped abrasive particles are disclosed in U.S. Pat. No. 5,201,916 to Berg; U.S. Pat. No. 5,366,523 to Rowenhorst; and U.S. Pat. No. 5,984,988 to Berg. In oneembodiment, the abrasive particles' shape comprised an equilateral triangle. Triangular shaped abrasive particles are useful in manufacturing abrasive articles having enhanced cut rates.SUMMARY Shaped abrasive particles, in general, can have superior performance over randomly crushed abrasive particles. By controlling the shape of the abrasive particle it is possible to control the resulting performance of the abrasive article. Different abrading applications can require different types of shaped abrasive particles. Therefore, having a process that can produce several different types of the shaped abrasive particles from the same process line is highly desirable. The inventors have determined that by controlling the process parameters and by using a polymeric production tooling having a plurality of mold cavities, different types of the shaped abrasive particles can be produced from the exact same mold. In particular, the inventors have determined a method to fracture the shaped abrasive particles while still in the mold to produce abrasive shards instead of solid, intact shaped abrasive particles. The inventors have also determined a method ofcontrolling the formation of the shaped abrasive particles while residing in the mold in order to form an opening through the shaped abrasive particle. Lastly, the inventors have also determined a method of controlling the formation of the shaped

The present invention relates to a method for the manufacture of hollow body elements such as nut elements for attachment to components normally consisting of sheet metal, in particular, for the manufacture ofhollow body elements having an at least substantially square or rectangular external outline by cutting individual elements by length from a section present in the form of a bar section or of a coil after prior piercing of holes into the section,optionally with subsequent formation of a thread cylinder, by using a progressive tool having a plurality of working stations in which respective operations are carried out. Furthermore the present invention relates to hollow body elements which aremanufactured in accordance with the method, to component assemblies which consist of a hollow body element and a sheet metal part and also progressive tools for carrying out the method and rolling mechanisms which can be used in combination with theprogressive tools. A method of the initially named kind and also corresponding hollow body elements and component assemblies are for example known in the non-prior published application PCT/EP2005/003893 of Apr. 13, 2005. It is the object of the presentinvention to so further develop the method of the initially named kind that hollow body elements, in particular rectangular nut elements can be manufactured at a favourable prices without having to load the tools that are used such that they failprematurely. Furthermore the hollow body elements that are manufactured in this way should have excellent mechanical characteristics, for example a high pull-out force, an excellent security against rotation and should moreover show a reduced notcheffect, so that the fatigue characteristics of component assemblies comprising a component normally consisting of sheet metal and hollow body elements mounted thereon can be improved also under dynamic loads. Furthermore, the hollow body elements shouldbe capable of being manufactured at an ex

shared by: Patents-281 on: Saturday, April 14, 2012

This invention relates to Micro Electro Mechanical Systems (MEMS), and more particularly to a three dimensional (3D) MEMS arm and system.BACKGROUND Micro ElectroMechanical Systems (MEMS) integrate mechanical elements, sensors, actuators, and/or electronics on a common silicon substrate through micro fabrication technology. The electronics are often fabricated using integrated circuit (IC)process sequences. The micromechanical components are often fabricated using compatible micromachining processes that selectively etch away parts of the silicon wafer or add new structural layers to form the mechanical and electromechanical devices. MEMS devices generally range in size from a micrometer (a millionth of a meter) to a millimeter (thousandth of a meter). Common applications include: inkjet printers that use piezoelectrics or bubble ejection to deposit ink on paper,accelerometers in cars for airbag deployment in collisions, gyroscopes in cars to detect yaw and deploy a roll over bar or trigger dynamic stability control, pressure sensors for car tire pressure, disposable blood pressure sensors, displays based ondigital light processing (DLP) technology that has on a chip surface several hundred thousand micro mirrors and optical switching technology for data communications.SUMMARY A micro assembly have a substrate and an operating plane coupled to the substrate. The operating arm is movable from an in-plane position to an out-of-plane position. One or more electric connections provide electric power from the substrateto the operating plane in the out-of-plane position. A tool is coupled to the operating plane. The tool is operable to receive electric power from the operating plane to perform work. The tool may be, for example, pliers, cutting tool. extension device, hot knife, magnetic bead implanter gun, and biopsy tool. Thus, the micro assembly may perform specific functions in three dimensions, such as reaching above and beyond theplane of the chip in order

Drive Mechanism For A Power Tool - Patent 8122972

Patents-281 — Sat, 14 Apr 2012 13:42:45 GMT

shared by: Patents-281 on: Saturday, April 14, 2012

The present invention relates to a drive mechanism for a power tool, and to a power tool incorporating such a mechanism. The invention relates particularly, but not exclusively, to a drive mechanism for a hammer drill, and to a hammer drillincorporating such a mechanism.BACKGROUND OF THE INVENTION Hammer drills are power tools that can generally operate in three modes of operation. The hammer drill will have a tool bit that can be operated in a hammer mode, a rotary mode and a combined hammer and rotary mode. For the hammer and combinedhammer and rotary mode, it is necessary to convert the rotary motion of the output shaft of the tool's motor into a reciprocating motion in order to power the hammering action. A mechanism for converting the rotary motion of the output shaft of the motor into reciprocating motion is described in GB2038986. Referring to FIG. 1 which shows a partially cut away perspective view of a drive mechanism described inGB2038986, and to FIG. 2 which shows a cross sectional view of the drive mechanism of FIG. 1, a hollow piston 2 is slidably mounted in a sleeve 4 such that the hollow piston 2 can reciprocate relative to the sleeve 4. A ram (not shown) is slidablydisposed in the hollow piston 2 in order to convert the reciprocation of the hollow piston two into a hammering action as will be known to persons skilled in the art. A crank pin 6 connects the hollow piston 2 to a circular crank plate 8 and comprises a cylindrical head 16 which is slidably disposed in a bearing 10 disposed on the rear of a hollow piston 2. The crank pin 6 also comprises a spherical head 12which is trapped in a spherical socket 14 disposed in the crank plate 8. The crank plate 8 is formed from two halves, 8a and 8b, which mate to define a spherical socket 14 for trapping the spherical head 12 therebetween. As the crank plate 8 rotates, the crank pin 6 alternately pushes and pulls the hollow piston 2 forwardly and rearwardly such that the hollow piston 2 reciprocate

Impact Rotary Tool With Drill Mode - Patent 8122971

Patents-281 — Sat, 14 Apr 2012 13:41:55 GMT

shared by: Patents-281 on: Saturday, April 14, 2012

BACKGROUND The present invention relates to power tools, and in particular to an impact rotary tool capable of switching between different modes of operation. A conventional combination drill may provide more than one mode of operation. For example, a first mode, referred to as a drill mode, provides continuous rotation of the output spindle without torque limitation during drilling operations. Asecond mode, referred to as an impact mode, provides the output spindle with impacting blows to rotate the output shaft in an impacting fashion. Despite the convenience of a dual mode tool, it would still be desirable to provide a tool where the output torque can be adjusted to limit the potential for stripping the heads or threads of fasteners due to excess torque from the tool.BRIEF SUMMARY The present invention provides an impact rotary tool that can be selectively switched between an impact mode and a drill mode. The impact rotary tool includes an impact mechanism with a hammer block connected to a drive shaft and an anvil thatis disposed concentrically with the drive shaft and configured to be selectively engaged by the hammer block. When the impact rotary tool is in the impact mode, the hammer block is movable along a longitudinal axis of the drive shaft against the biasingforce of a spring and the hammer block reciprocatingly engages the anvil causing it to rotate. When the impact rotary tool is in the drill mode, the hammer block substantially constantly engages the anvil causing the anvil to rotate. The impact rotary tool includes a mode selector to selectively transfer operation between an impact mode and a drill mode. When the mode selector is in the impact position, the stopper does not engage the hammer block. When the mode selectoris in drill mode, the stopper engages the hammer block to maintain substantially constant contact between the hammer block and the anvil. The present invention also provides an impact rotary tool that can selectively transfer o

Three-way Ratchet Drive Mechanism - Patent 8122791

Patents-282 — Sat, 14 Apr 2012 13:28:38 GMT

shared by: Patents-282 on: Saturday, April 14, 2012

The present invention relates to a ratchet drive mechanism for a screwdriver bit or other work tool. There are a wide variety of known designs for ratchet tools. Typically, such tools have two modes of operation, either one of which may be selectively set by the user. In the first mode (for example to tighten a screw) ratcheting operation isenabled in a clockwise direction. In the second mode (for example to loosen a screw) ratcheting operation is enabled in an anti-clockwise direction. However, disadvantageously, many of such tools typically have no third or non-ratcheting mode of operation or setting where ratcheting behaviour can be locked out/disabled and the drive mechanism of the tool engages whether the tool is turnedclockwise or anti-clockwise. The advantage of such a third mode can arise, for example, when a user wants to make minor adjustments to the tightness of a screw or to slightly loosen then retighten a screw. In this situation, it can be quiteinconvenient to have to switch back and forth between clockwise and anti-clockwise modes of ratcheting operation. There are at least some ratcheting tools which offer a non-ratcheting mode of operation. An example is that described in U.S. Pat. No. 6,305,248 (Rowlay) granted on Oct. 23, 2001. In this patent, one stated object is to provide a ratchetmechanism which is of short length. It appears to be suggested that this object is compromised by conventional drive mechanisms where pawls extend in the axial direction of a shaft. This is agreed. But, the alternative mechanism suggested by Rowlayappears to be a rather complicated pawl rocking mechanism. Further, the Rowlay mechanism does not appear to combine the objective of short length with strength and long term durability. Those relatively few tools which do offer a non-ratcheting mode of operation, are considered relatively complex in structure or operation. Further, they are not considered well adapted for smooth ratcheting operation under hi

Patents-282 — Sat, 14 Apr 2012 13:28:24 GMT

shared by: Patents-282 on: Saturday, April 14, 2012

This invention relates to a device for driving or removing fasteners from a substrate, such as a screwdriver, that includes a ratcheting mechanism to assist in driving the fastener.BACKGROUND OF THE INVENTION In the past a variety of different types of devices have been developed to drive fasteners into a substrate for various purposes. The type of device most often utilized to drive the fastener is a screwdriver or similar device that translatesthe rotation of the screwdriver by the individual into rotation of the fastener to urge the fastener into the desired substrate. On many occasions, the particular location where the fastener needs to be located, or the type of substrate into which the fastener is to be driven creates a certain amount of difficulty in driving the fastener into the substrate. To providesome assistance in driving the fasteners in these more difficult situations, many of these devices are constructed with a ratcheting mechanism. The ratcheting mechanism allows the individual to restrict the rotation of the driver to a single direction,which eases the difficulty of driving the fastener. Nevertheless, the devices, whether including a ratcheting mechanism or not, produces only a one to one ratio between the rotation of the device by the individual and the corresponding rotation of the fastener. As a result, it normally takes asignificant amount of time to completely drive the fastener into the substrate. In an attempt to increase the speed of driving a fastener into a substrate, certain prior art devices have been developed that can alter the ratio of the rotation of the handle of the device with respect to the driving bit of the device, tothereby increase the speed of driving the fastener into the substrate. One device of this type is disclosed in Murphy U.S. Pat. No. 6,899,653, which discloses a fastener with a gear assembly. In this device, the fastener includes a plate having anumber of openings formed therein. The plate is connected

1. Field of the Invention The present invention relates to a torque socket assembly, and more particularly, to a torque socket assembly with improved structure and providing a stable torque value 2. Description of Related Art A conventional torque socket assembly commonly known in accordance with the prior art comprises a receiving portion, a driving portion, and a middle portion disposed in between the receiving portion and the driving portion. The receivingportion has a quadrangular hole for adapting to co-operate with a driving tool. The driving portion is a polygon-shaped hole for adapting to receive a fastener (i.e. a bolt). The middle portion has a plurality of embossed patterns and a plurality ofsmooth faces alternately and annularly formed on the outer periphery thereof. The embossed patterns provide increment to the friction when the socket assembly is grasped by hands, such that a user may selectively adapts the socket assembly to a drivingtool or simply grasps the socket assembly by hands for operation. However, the conventional socket assembly bears several disadvantages. First of all, the conventional socket assembly does not include a torque adjusting unit therefore it is not capable to provide a predetermined torque. When in operation,the user can merely tightened the fastener with an object, and is unable to determine whether the torque applied is sufficient to securely fasten the fastener with the object. In addition, the user is not acknowledged if the torque applied has reachedthe torque required, which may consequently lead to over-tightening of the fastener, such that the structure of the socket assembly is easily damaged due to over-tightening. Nevertheless, high precision in a torque applied is often required whenapplying a socket assembly to fasten a fastener with the object; even minor errors in the torque applied may lead to unexpected result. Due to the lack of the torque adjusting unit of the conventional socket assembly, when

This invention relates to pliers, and more particularly, to self-adjusting locking pliers that enable the clamping force generated by the device to be pre-set. Self-adjusting or auto-adjusting pliers are known. Such pliers have jaws which are self-adjusting accordingly to the size of the work piece to be grasped between the jaws. Examples of such self-adjusting pliers are disclosed in U.S. Pat. No.6,065,376 and U.S. Pat. No. 6,279,431. Also known are locking pliers which incorporate an over-center compound toggle locking mechanism or linkage whereby when the moveable jaw of the pliers is adjusted to seize a work piece firmly between the moveable and the fixed jaw and thehandles are tightly compressed, the toggle mechanism locks the hand tool onto the work piece. Examples of this type of pliers are disclosed in U.S. Pat. No. 5,056,385 and U.S. Pat. No. 6,626,070 (locking pliers sold under the trademark VISE-GRIP). Self-adjusting locking pliers are also known. Such pliers include jaws that are self-adjusting according to the size of the work piece to be clamped between the jaws and that use an over-center compound toggle locking mechanism to firmly clampthe work piece. One example of such a pliers is disclosed in U.S. Pat. No. 6,941,844. Another example of such a pliers is disclosed in U.S. Pat. No. 6,591,719. Self-adjusting locking pliers are not all capable of generating the high clampingforces that are expected of locking pliers and some designs are susceptible to back drive forces that can inadvertently force open the pliers under high loads. Thus, an improved self-adjusting locking pliers is desired.SUMMARY OF THE INVENTION In one embodiment the self-adjusting locking pliers of the present invention include a fixed assembly having a body that forms a fixed handle and a plate or fixed jaw supported at one end thereof. A lever or movable handle is pivotablyconnected to the body. A moveable jaw is pivotably supported on the body at a locking s

The present invention relates to wind turbines, and more particularly, to a method and tool for aligning fasteners with corresponding holes in a wind turbine tower base.BACKGROUND OF THE INVENTION Tower structures, such as a wind turbine towers, may be attached to a tower foundation by bolting a base of the tower to a fastener, such as an anchor bolt, secured in the tower foundation. In an exemplary erection method, anchor bolts may beembedded vertically in the foundation in a pattern to match a corresponding pattern of vertical holes in a base of the tower, such as in a flange portion of the base. The base may be vertically lowered over the foundation and positioned to align theanchor bolts protruding from the foundation with the holes in the flange. However, there may be some slight misalignment of the anchor bolts with respect to their corresponding holes. Such misalignments may require that the anchor bolts be urged intoalignment with the holes so that the base of the tower can be lowered over the anchor bolts to rest on the foundation.

Thisapplication is the U.S. national phase of International Application No. PCT/EP2005/011571 filed 28 Oct. 2005 which designated the U.S. and claims priority to EP 04425928.1 filed 20 Dec. 2004, the entire contents of each of which are herebyincorporated by reference. This invention relates to a device for the adjustment of a gland nut according to the preamble of Claim 1. In particular, this invention finds application in the adjustment of a gland nut in pumping equipment, such as alternating pumps. The use of annular seals in pumping equipment provided with alternating systems or rotating shafts for the movement of a fluid is known. These seals, typically made of resilient or compressible materials, prevent the occurrence of leaks aroundthe rotating shaft or alternating system of a pump and as a consequence leakage of the pumped fluid outside the pump. Typically these seals, in the shape of rings, are housed in a gland box which also comprise a gland arranged as a collar on the shaft or piston which is capable of axially compressing the sealing rings against a fixed wall of the gland box. The seal is obtained by making use of the axial compression force exerted by the gland on the sealing rings which deform in a radial direction as the result of this compression force, pressing against and adhering to the cylindrical wall of theshaft or piston and therefore preventing escape of the pumped fluid present in the pump. It should be noted that a leak of the pumped fluid is however always present, although in negligible quantities. However it should be pointed out that while the pump is in operation the sealing rings are worn away by friction against the walls of the alternating piston or rotating shaft. This causes appreciable losses around the gland which are notsustainable, with a consequent fall in the volumetric capacity of the pumping system. It should also be pointed out that the fluids used in these pumping systems often contain potentially hazardous c
