Football With Inflatable Bladder Having Integral Grip Areas - Patent 8152664
1. Field of the Invention The present invention relates to a football with multiple contoured grip areas for greater contact and better control when the ball is thrown. 2. Background of the Invention Most inflatable sports balls are made by one of two main constructions: a traditional construction in which an inner bladder is surrounded by outer panels stitched together to contain the inflated bladder; and a carcass construction in whichouter panels are laminated to an inner bladder. Examples of balls of traditional construction include some soccer balls, volleyballs and footballs which have pieced and stitched outer panels. An example of a ball of carcass construction is a basketballwhich has an integral outer cover. Conventional footballs are constructed in the traditional way by surrounding an inner bladder with an outer skin formed of multiple panels stitched together. In traditional construction, the bladder is inserted into an opening in the outerskin, and the outer skin is laced together to close the opening. The lacing is raised and extends some distance along the length of the football. The laces serve another function as well. When throwing the ball, a thrower generally grips the ball withthe fingers along the laces. The lacing enhances the grip on the ball and provides a locus for imparting a spiral motion to the ball as it leaves the thrower's hand to thereby enhance the flight of the ball. This traditional design is still used today even though modern manufacturing methods and materials do not necessarily require lacing together of the outer skin. In some footballs, laces or lace-like structures are molded onto the surface of theball even if they are not necessary for construction. The laces are still a reference point for a thrower and the locus for the initiation of a spiral motion. An example of a lace-like element is disclosed in U.S. Pat. No. 5,383,660 to Adler et al.in which an elongated indentation array is provided on the surface.
Lacrosse Training Method And Apparatus - Patent 8152661
The present invention relates to training methods for projecting objects and, in particular, a lacrosse training stick including a laser generator and a method of using the lacrosse stick to teach and practice lacrosse stick movements.BACKGROUND OF THE INVENTION Lacrosse in an increasingly popular sport with a growing number of participants. The sport is played on a field where a hard rubber ball is passed from player to player and thrown towards a goal to score. The ball is handled with sticksincluding a shaft and a head. During the passing, throwing, and shooting of the ball, the lacrosse stick is typically actuated through an arc such that the head of the stick undergoes a significant rotational acceleration. A player drives or pushes thebutt-end of the stick, with the bottom hand towards the target, while at the same time pulling down on the bottom of the handle in order to shoot on goal. The effectiveness of the throw is often dependent on the throwing technique or form that is used. Players often struggle to attain a proper technique when using a lacrosse stick to throw a ball, especially novice players and athletes attemptingto throw with their non-natural hand (i.e., a righty throwing left-handed and a lefty throwing right-handed). Typical throwing errors are often related to improper motion of the head of the lacrosse stick. One error occurs when the plane of the head isnot oriented properly to the direction of the desired throw. Another error occurs when the timing of the shot initiation is improper. Accordingly, it would be desirable to provide a lacrosse training apparatus and method that trains a user to utilize a correct throwing technique.SUMMARY OF THE INVENTION A training device for teaching proper mechanics of aiming and propelling a lacrosse ball is disclosed. The training device is a lacrosse stick including a shaft portion, a head portion, and an end cap. The head portion is configured to receiveand support a lacrosse ball. The end c
Golf Club Head With Improved Performance - Patent 8152652
The present invention relates generally to a golf club head that is capable of achieving an improved sweet spot, defined as a portion of the striking face that has at least 99.7% of the maximum ballspeed. More specifically, the presentinvention relates to a golf club head wherein the sweet spot covers at least 1.5% of the entire total striking face of the golf club head. Even more specifically, the present invention relates to a golf club head with a significantly elliptical shapedstriking face with an elliptical factor of greater than about 0.50 to achieve an improved sweet spot, wherein the elliptical factor is defined as the length of the minor axis divided by the length of the major axis. The present invention may also relateto a golf club head with a tilted bulge and roll radius to further improve the performance of the golf club head.BACKGROUND OF THE INVENTION In the competitive industry of golf club design, distance and accuracy are two of the most important performance factors that help define the desirability of a metal wood type golf club. Although some may argue that the look, feel, and sound ofa golf club may influence their opinion of a golf club; there is no arguing that the performance factors play a major role in determining the desirability of a golf club. The performance factors of maximizing distance while maintaining accuracy becomeseven more prevalent in a metal wood type golf club head. Unlike iron type golf club heads where accuracy of a golf shot clearly trumps the distance benefits gained by any individual golf club, metal wood type golf club heads are designed to allow agolfer to hit the golf ball as far as possible in and as straight as possible. In order to maximize distance while maintaining accuracy of a metal wood type golf club head, metal wood type golf clubs have been designed with the objective of maximizing the distance of a golf ball struck by a golf club head close to thegeometric center of the golf club head. This geom
Three-layer-core Golf Ball Having Highly-neutralized Polymer Outer Core Layer - Patent 8152654
The present invention is directed to golf ball compositions and, in particular, polymer compositions including highly-neutralized polymers and blends thereof.BACKGROUND OF THE INVENTION Conventional golf balls can be divided into two general classes: solid and wound. Solid golf balls include one-piece, two-piece (i.e., solid core and a cover), and multi-layer (i.e., solid core of one or more layers and/or a cover of one ormore layers) golf balls. Wound golf balls typically include a solid, hollow, or fluid-filled center, surrounded by a tensioned elastomeric material, and a cover. It is also possible to surround a hollow or fluid-filled center with a plurality of solidlayers. Solid balls have traditionally been considered longer and more durable than wound balls, but many solid constructions lack the "feel" provided by the wound construction. More recently, by altering ball construction and composition, manufacturers have been able to vary a wide range of playing characteristics, such as compression, velocity, "feel," and spin, optimizing each or all for various playing abilities. In particular, a variety of core and cover layer(s) constructions, such as multi-layer balls having dual cover layers and/or dual core layers, have been investigated and now allow many non-wound balls to exhibit characteristics previously maintainable ina solid-construction golf ball. These golf ball layers are typically constructed with a number of polymeric compositions and blends, including polybutadiene rubber, polyurethanes, polyamides, and ethylene-based ionomers. Ionomers, and in particular ethylene .alpha.,.beta.-ethylenically unsaturated carboxylic acid copolymers or a melt processible ionomer thereof, are a preferred polymer for many golf ball layers. One problem encountered with the use of ionomersas stiff layers, however, is the unprocessability of the material as the percent of neutralization of the acid group increases. Ionomers are stiffened by increasing the amount
High Performance Golf Ball Having A Reduced-distance - Patent 8152656
FIELDOF THE INVENTION The present invention relates to golf balls, and more particularly, to a golf ball having a reduced distance while maintaining the appearance of a normal high performance trajectory.BACKGROUND OF THE INVENTION Solid golf balls typically include single-layer, dual-layer (i.e., solid core and a cover), and multi-layer (i.e., solid core of one or more layers and/or a cover of one or more layers) golf balls. Solid balls have traditionally been consideredlonger and more durable than predecessor wound balls. Dual-layer golf balls are typically made with a single solid core encased by a cover. These balls are generally most popular among recreational golfers, because they are durable and provide maximumdistance. Typically, the solid core is made of polybutadiene cross-linked with zinc diacrylate and/or similar crosslinking agents. The cover material is a tough, cut-proof blend of one or more materials known as ionomers, such as SURLYN.RTM., soldcommercially by DuPont or IOTEK.RTM., sold commercially by Exxon. Multi-layer golf balls may have multiple core layers, multiple intermediate layers, and/or multiple cover layers. They tend to overcome some of the undesirable features of conventional two-layer balls, such as hard feel and less control, whilemaintaining the positive attributes, such as increased initial velocity and distance. Further, it is desirable that multi-layer balls have a "click and feel" similar to wound balls. Additionally, the spin rates of golf balls affect the overall control of the balls in accordance to the skill level of the players. Low spin rates provide improved distance, but make golf balls difficult to stop on shorter shots, such asapproach shots to greens. High spin rates allow more skilled players to maximize control of the golf ball, but adversely affect driving distance. To strike a balance between the spin rates and the playing characteristics of golf balls, additionallayers, such as intermediate layers, outer
Radial Baseball Bat - Patent 8152662
The invention is in the field of baseball bats.BACKGROUND Standard baseball bats include wood baseball bats consisting of a single piece of wood, laminated wood baseball bats comprised of multiple solid sections of wood adhered together, and metal baseball bats. A wood baseball bat requires a greaterlevel of skill to use than a metal baseball bat. However, people who are interested in the integrity of the game of baseball, interested in preparing for entry into the professional baseball leagues where wood baseball bats are the only bats permittedto be used, or who prefer the sound and appearance of a wood baseball bat, seek to find wood baseball bats with the best performance and durability features available. Major League Baseball (MLB) requires the use of wood bats. These bats do not, however, have to be made of a single piece of wood. The MLB rules committee, for example, has approved a wood bat made of four different pieces of wood, each of adifferent species, glued together. There have been recent safety concerns with metal bats. Metal bats have a "trampoline" effect when a ball is hit. The metal deforms and bounces back adding a certain amount of unpredictable direction to the ball. Thus infielders, such as apitcher or a third baseman, can be injured when a high velocity ball comes off a metal bat with a direction that cannot be readily predicted by observing the bat hit the ball. The infielders are hit before they can react. Thus there is a growingmovement among Little League and public school baseball teams to require the use of wooden bats. Single piece wooden bats, however, have their own safety drawbacks. Single piece wooden baseball bats are vulnerable to breaking into two pieces when a ball is hit. The flying piece of bat can injure a nearby player. A more subtle safety and comfort issue is a single piece wooden baseball bat will "sting" the hands of a batter when a baseball is struck away from the "sweet spot" of the bat. The stinging caus
Thick Inner Cover Multi-layer Golf Ball - Patent 8152653
This invention relates generally to golf balls with a core, a thick intermediate layer, and a cover, more particularly single-layer cores having a surface hardness equal to or less than the center hardness to define a "negative" hardnessgradient across the core.BACKGROUND OF THE INVENTION Golf balls have been designed to provide particular playing characteristics. These characteristics generally include initial ball velocity, coefficient of restitution (COR), compression, weight distribution and spin of the golf ball, which canbe optimized for various types of players. Generally, the hardness of a golf ball or a golf ball core is one of many factors used in designing golf balls. Typically, when a golf ball is hard, e.g., possessing a high compression value and low deformation, it typically has high COR andhigh initial velocity after impact with a golf club. However, a hard golf ball has a firm feel and can be difficult to control around the greens. A softer golf ball, e.g., having a lower compression value and high deformation, feels better and iseasier to control with short iron clubs for greenside play. Recent advancements in golf ball design can produce golf balls with the combination of low compression for soft "feel" and high COR for long flight distance. The COR for low compression golf balls, however, decreases at higher impact speed withgolf clubs. Solid golf balls are typically made with a solid core encased by a cover, both of which can have multiple layers, such as a dual core having a solid center and an outer core layer, or a multi-layer cover having an inner. Generally, golf ballcores and/or centers are constructed with a thermoset rubber, typically a polybutadiene-based composition. The cores are usually heated and crosslinked to create certain characteristics, such as higher or lower compression, which can impact the spinrate of the ball and/or provide better "feel." These and other characteristics can be tailored to the needs of golfers of d
Method And Apparatus For Analyzing A Pitched Ball - Patent 8152658
BACKGROUND 1. Field This invention relates generally to sports. More specifically, this invention relates to the analysis of a pitched ball. 2. Description of Related Information Pitchers and hitters in sports such as baseball and softball are still commonly taught according to largely anecdotal methods that neglect various aspects of the mechanics of pitches. Conventional thought remains that by throwing pitches atvarious elevations, hitters will be forced to change their eye level up and down and offset their focus to many different heights. Pitchers are also taught to throw different speed pitches, in order to upset a hitter's timing. Pitchers also attempt toconfuse hitters by locating the ball on the inside, outside, and middle parts of the strike zone. However, each of these aspects are often simply varied randomly, without regard to any systematic method of characterizing pitches. Accordingly, continuing efforts exist to analyze the mechanics of pitches, and characterize them in ways that yield better instruction for both pitchers and hitters.SUMMARY The invention can be implemented in numerous ways, including as a method, an apparatus, and a computer readable medium. Several embodiments of the invention are discussed below. As a method of analyzing a pitched ball from a pitcher to a batter, the pitcher and the batter separated by a first distance, one embodiment of the invention comprises measuring a first speed of the ball thrown over the first distance. Adestination of the ball is located within a region proximate to the batter. A second speed of the ball is then calculated from the first speed of the ball and the destination. Another embodiment of the invention is a computer readable medium having computer executable instructions thereon for a method of analyzing a pitched ball from a pitcher to a batter that are separated by a first distance, the method comprisingmeasuring a first speed of the ball thrown over the first distance. Also included
Apparatus For Handling Golf Ball And Golf Tee - Patent 8152657
FIELD OF THE DISCLOSURE The present disclosure relates generally to a golf apparatus, and, more particularly, to an apparatus for handling a golf ball and a golf tee.BACKGROUND OF THE DISCLOSURE Typically, a user playing golf needs to put a golf ball in a hole by using a golf club and by following a set of rules. The user places the golf ball on a tee before hitting the golf ball with the golf club for the first time. The tee includesa pin-shaped end portion and a platform-shaped end portion for supporting the ball. The pin-shaped end portion is inserted in the ground and the platform-shaped end portion is positioned at an elevation from the ground. Generally, a person, such as a player or a caddy, may need to fix the tee in the ground and place the ball on the tee. Furthermore, the person may need to remove the golf ball from the hole after the golf ball has been putted. All these tasksrequire the person to bend down and fix/remove the golf ball and the tee. Bending down to fix/remove the golf ball and the tee may be inconvenient for the person. Particularly, people with a back problem may find it even more inconvenient to bend downto fix/remove the golf ball.SUMMARY OF THE DISCLOSURE An apparatus for handling a golf ball and a golf tee is provided. The apparatus may include a body that may include a first opening, a second opening and a chamber and a chamber that may be communicated with the first opening and the secondopening. The apparatus may include a handle assembly that may be associated with the second opening of the body. Further, the apparatus may also include a biasing assembly that may be capable of being actuated by the handle assembly. Furthermore, theapparatus may also include a drive assembly that may be capable of being actuated by the biasing assembly. Moreover, the apparatus may include a clamshell retainer that may be associated with the second opening of the body. The clamshell retainer mayhave a pair of clasping members movable be
Basketball Training Device - Patent 8152660
The present invention relates to a basketball training device, more specifically but not by way of limitation, a basketball training device that provides training to a user for shooting a basketball while learning to manage a defensive playerobstacle such as but not limited to a hand during the shooting process without the requirement of a second individual so as to simulate an environment that will be encountered by the player during a basketball game.BACKGROUND Millions of individuals engage and routinely participate in recreational sport of many varieties. Participants of the sports typically will engage in various practice routines so as to increase their ability and to manage certain situations ortechniques that may be required during the playing of the game. One such sport that millions routinely engage in is basketball. Basketball requires a variety of skills that must be developed through hours of practice such as but not limited to, dribbling, passing and shooting. Participants of basketball will routinely practice the aforementioned skills in order toimprove their performance and increase their contribution to the team on which they play. One problem with many of these drills is that the requirement of more than one player in order to execute the drill. For example, in order to increase a player'sability to pass, most effective drills require a minimum of two people to properly execute the drill so as to increase the performance of the athlete. Shooting in another important skill in the game of basketball. Athletes must not only perfect their style of shooting such as but not limited to jump shots or free throw shooting, they must also learn to manage and execute their shot in thepresence of defenders. One common practice drill for players to learn to execute their shooting in the presence of defenders is to utilize at least two players wherein on player will engage in offense and practice their shooting while the other playerengages in defense and
Trackable Arrow - Patent 8152663
1. Field of the Invention The present invention relates to the field of arrows, such as archery arrows and hunting arrows and more particularly to archery or hunting arrows that can be found more easily in the dark. 2. Background of the Related Art Archery and hunting with bow and arrows is one of the longest-lived sports and has been a hunting method common to a wide range of cultures throughout the world. The arrow for hunting has an arrowhead mounted on the front end thereof, the arrowhead being very pointed at the front end portion thereof. At the moment where the arrow for hunting is moved from a bowstring of a bow and hits the body of ahunting target, the pointed end of the arrowhead cuts into the body of the hunting target to cause the arrow for hunting to get stuck into the body of the hunting target or competitive target, such that the arrow remains fixed in the hit target. The arrowhead is fixed to a shaft which is used to receive and transmit kinetic energy from a drawn bowstring and to carry the arrowhead to its target is a stable flight path. The shaft is designed to provide an important balance betweenrigidity and flexibility which is needed at the different stages of aim, launch and flight. Wood shafts, particularly of Yew wood have been preferred. To further stabilize the flight of the arrow, vanes have been provided to keep the shaft and the arrow oriented during flight. This is often done not just by the vanes (originally provided on the rear of the shaft by split and shaped feathers)keeping the flight path straight, but also by rotating the shaft and the arrow. The rotation of the shaft and the arrow tends to overcome any deformities in the shape, curvature or improper weight distribution of the shaft, feathers and arrowhead. Thisis accomplished by moving the radial deformities about the axis of the shaft in flight by rotating the arrow. Arrows of quality manufacture have become increasing expensive and efforts are made to preserve the li
Multi-piece Golf Ball Comprising Low Hardness Gradient Core - Patent 8152655
This invention relates generally to golf balls with cores having one or more layers, any of the layers having a `negative` or `positive` hardness gradient, trans gradient, or both. More particularly, the golf ball has a core of one or morelayers where at least one layer, preferably a single, solid core, has a low, "positive" hardness gradient and concurrently includes a trans-polybutadiene gradient.BACKGROUND OF THE INVENTION Solid golf balls are typically made with a solid core encased by a cover, both of which can have multiple layers, such as a dual core having a solid center and an outer core layer, or a multi-layer cover having an inner. Generally, golf ballcores and/or centers are constructed with a thermoset rubber, typically a polybutadiene-based composition. The cores are usually heated and crosslinked to create certain characteristics, such as higher or lower compression, which can impact the spinrate of the ball and/or provide better "feel." These and other characteristics can be tailored to the needs of golfers of different abilities. From the perspective of a golf ball manufacturer, it is desirable to have cores exhibiting a wide range ofproperties, such as resilience, durability, spin, and "feel," because this enables the manufacturer to make and sell many different types of golf balls suited to differing levels of ability. Heretofore, most single core golf ball cores have had a conventional hard-to-soft hardness gradient from the surface of the core to the center of the core, otherwise known as a "positive hardness gradient." These gradients, however, aretypically quite large, upwards of 15, 20, even 25 or more Shore C hardness points. The patent literature contains a number of references, additionally, that discuss a hard-surface-to-soft-center hardness gradient across a golf ball core. U.S. Pat. No. 4,650,193 to Molitor et al. generally discloses a hardness gradient in the surface layers of a core by surface treating a slug of curable elasto
Football Holder - Patent 8152659
1. Field of the Invention The present invention relates to a holder that straps onto a quarterback's waist and legs to hold extra footballs during football practice so that the quarterback has extra footballs to throw for each practice play. 2. Description of the Related Art Currently during football practice, a quarterback will throw a football to one person for each play. This results in most of the players engaging in many plays where they do not get an opportunity to practice receiving or catching the football. It would be desirable if the quarterback could throw several footballs during each practice play so that more of the players had an opportunity to practice receiving or catching the football. Unfortunately, the quarterback does not have enough hands tohold more than one football at a time and still be able to throw the ball properly. What is needed is a football holder that allows the quarterback to throw a football unobstructed and then quickly grab additional footballs so that multiple footballscan be thrown to various receivers during each practice play. The present invention addresses this need by providing a holder for holding extra footballs on the side or hips of the quarterback until the quarterback is ready to throw the extra footballs. The holder attaches to the quarterback with a beltand a couple of straps. A belt extends around the waist of the quarterback and through the top end of one or more of the holders so that each of the holders is located on a side of the quarterback's hips. If two holders are to be used, a first legstrap extends around the upper portion of the left leg of the quarterback and through a bottom end of one of the holders to secure the first holder to the side of the left leg of the quarterback. A second leg strap extends around the upper portion ofthe right leg of the quarterback and through a bottom end of the other one of the holders to secure the second holder to the side of the right leg of the quarterback.
Golf Putter And Grid For Training A Golf Putting Method - Patent 8152649
(1) Field of the Invention The present invention relates to golf equipment and, more specifically, to golf training equipment. (2) Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98. The traditional "pendulum swing" of a putter, used by most modern golfers, has too many random variables such as the height of the swing, distance of the backswing, speed of the club head on return to the ball for the strike, direction of theaim of club head direction, and rotation of the club head for the mind and muscles to be adequately trained for a consistently successful putt. The traditional pendulum swing is confronted with infinite variables for every putting event and is notrecordable and correctable with a device of sufficient capacity that enables making corrections in the putting event. The "pendulum swing" faces its own unique direction, undulation and speed requirements with little opportunity for correction. Various prior arts disclose a method and apparatus for training a golfer in practicing traditional "pendulum swing" of a putter as described below. U.S. Published Patent Application No. 2006/0029916 A1 (Boscha) discloses a golf putter for training a golf player, wherein the golf putter has a handle, a head, and sensing unit for sensing parameters. U.S. Published Patent Application No.2007/0249428 A1 (Pendleton et al.) discloses a putting training device comprising a surface over which a golfer executes a putting stroke, an electric field generator, an electric field detector, a plurality of electrodes responsive to the electric fieldgenerator each for producing an electric field and wherein as the golfer executes the putting stroke one or more of the electric fields is perturbed, and wherein the electric field detector detects the perturbed electric field to determine parametersrelated to putter head movement. U.S. Pat. No. 6,375,579 B1 (Hart) discloses a dynamic laser based golf swing analysis system having single a
Golf Swing Practice Device For Engaging A Golfer's Knee Or Calf Muscle And Preventing Body Sway During A Golf Club Back Swing - Patent 8152650
(a) Field of the Invention This invention relates to a golf training device for improving a golfer's swing and more particularly, but not by way of limitation, to a golf swing practice device for standing on and engaging the outside of a golfer's knee or calf muscle. Thepractice device helps prevent sway of the body and helps maintain knee flex during a golf club's back swing thereby helping to increase power and center of balance when hitting a golf ball during the club's follow through. (b) Discussion of Prior Art Heretofore, the have been any number of different types of golf swing training devices for helping improve a golfer's back swing and follow through. None of these training and practice devices provide the unique structure, function andadvantages of the subject invention as described herein.SUMMARY OF THE INVENTION In view of the foregoing, it is a primary objective of the subject invention to provide an adjustable golf swing practice device for both right and left handed golfers. A portion of the device is adapted for standing on by the golfer's shoe tohold it in place. The device includes an adjustable leg brace for engaging the outside of the back leg at the knee or calf muscle during a golf club back swing. A key feature of the invention is the device prevents the back leg from straightening out or the locking of the knee during the club back swing. By keeping the back leg flexed and stationary, the golfer can build a powerful body coil plusmaintain a center of balance and position for consistent shot making. Using the device, the golfer can feel what its like to shift his or her weight to the inside of the back foot. Then, the golfer can push off correctly from the back foot thusshifting the weight properly to the front leg. Also, as the golfer becomes comfortable in using the device, only slight pressure on contact can be used rather than using it as a support brace. Still another object of the invention is the practice device is lightweigh
