GRIP AID DEVICE FOR BATS USED FOR SPORTS
Grip aid devices and methods for developing proper technique and mechanics for gripping a bat used for sports are disclosed. The grip aid device may include first and second ridges on an elongated body. The first and second ridges are aligned parallel to a length of the elongated body and protrude outward from an outer surface of the elongated body. The second ridge is spaced about the circumference of the body from the first ridge. The grip aid device can be removably installed on a bat or can be fashioned integral with a bat handle. The opposing ridges of the grip aid device position the player's hands in a wrist-over-wrist alignment that enables the player to maintain a generally planar travel path of the bat through a hitting zone.
The present invention relates generally to sports equipment and, in particular, to grip aid devices for bats used in sports to develop proper grip technique.
BACKGROUNDVarious sports around the world, such as baseball, softball, or cricket, for example, involve the use of a bat to strike a ball traveling through a hitting zone in order to place the ball in a field of play. Bats used for these sports are often made of wood or metal, such as aluminum, and can have a handle that can be gripped by a player for swinging the bat. The manner in which a player grips the bat can have a dramatic effect on the ability of the player to hit the ball with the bat. Grip technique can also impact the trajectory of the ball leaving the bat and the power transferred from the player to the ball through contact with the bat.
Improved grip aid devices that provide better alignment of the hands and wrists are needed for bats.

Sports rules, such as the rules of baseball and softball, generally prohibit the use of training aids or practice devices during games, which necessitates either the removal of the grip aid device 10 from the bat 12 or, in the case of the grip aid device 10 formed integral with the bat 12 (
The grip aid device 10 can be made of a resilient material that is capable of being plastically deformed or expanded outward and of returning to its original shape following the expansion. The resilient material is strong enough to expand over the knob 22 of the bat 12 without ripping and is durable enough to withstand repeated installation on and removal from the bat 12 without substantial degradation of the grip aid device 10. Materials suitable for the grip aid device 10 can have a tensile modulus (i.e., elasticity) in a range of about 300 pounds per square inch (psi) to about 1000 psi in one embodiment, or about 600 psi to about 1000 psi in another embodiment, or about 700 psi to about 1000 psi in yet another embodiment. Resilient materials include, but are not limited to natural rubbers, such as polyisoprene, or synthetic rubbers, which include, but are not limited to, silicone rubber, styrene-butadiene rubber, isoprene rubber, chloroprene rubber, polyacrylate rubber, polyester urethane rubber, other synthetic rubber, or combinations thereof. In one embodiment, the grip aid device 10 can be a silicone rubber. One or more colorants, dyes, or pigments can be added to the material used to make the grip aid device 10. The grip aid device 10 can be made by injection molding or transfer molding, both of which are well-known in the art. A brand logo or other textured design can be added to the surface of a mold used for the injection molding or transfer molding in order to incorporate the brand logo or other textured design into the outer surface 26 of the body 24, outermost surface 40 of the first and second ridges 14, 16, or any other surface of the grip aid device 10.

In accordance with embodiments of the invention, the implementation of multiple ridges may overcome deficiencies of grip aids that are included on a grip with a single ridge that fails to provide an adequate mechanism for aligning the player's wrists. With the knuckles aligned on the single longitudinal ridge, the player is still free to move the wrists away from each other by, for instance, flaring out the elbows. Allowing the wrists to rotate away from each other creates a “hole” or loop in the player's swing. Spacing the wrists apart such that the wrists are not in a wrist-over-wrist alignment causes a player to roll the top hand over the bottom hand when the bat is traveling through a hitting zone. Rolling the hands over in the hitting zone can cause the barrel of the bat to loop out of a plane of the swing, which can result in the player mis-hitting the ball traveling through the hitting zone or completely missing the ball altogether.
The grip aid device 10 disclosed herein minimizes or eliminates this looping of the barrel 20 of the bat 12 in the hitting zone caused by rolling the top wrist over the bottom wrist. As previously described, grip aid device 10 aligns the knuckles as well as properly aligning the hands in a wrist-over-wrist configuration. Positioning the hands in a wrist over wrist alignment enables a player to keep the bat 12 traveling in a continuous plane through the hitting zone and minimizes or eliminates the looping movement of the barrel 20 of the bat 12 caused by rolling the top hand over the bottom hand. Maintaining a consistently planar swing through the hitting zone results in better contact with the ball and better transfer of power and trajectory to the ball, which, in baseball and softball, leads to increases in desirable hits, such as ground balls and line drives, for example.
In an embodiment, the use of exactly two ridges 14, 16 may permit the middle knuckles of both hands to contact and be aligned with one of the ridges and the v-shaped notches of both hands to contact and be aligned with the other of the ridges. In this embodiment, a third ridge is not needed to provide the desired alignment between the hands and the grip aid device 10 on the bat 12. In addition, the use of only a single ridge is not adequate to provide the desired alignment between the hands and the grip aid device 10 on the bat 12.
The grip aid device 10 can be used to help a player develop a proper grip of the bat. A method for improving a player's grip can include providing a grip aid device 10 as disclosed herein; installing the grip aid device 10 on the handle 20 of a bat 12; positioning the player's hands on the grip aid device 10 as described herein to align the knuckles and align the wrists in a wrist over wrist alignment; and engaging in repeated swinging of the bat 12 through a hitting zone, while having the wrists properly aligned on the handle 20 by way of the grip aid device 10. The grip aid device 10 can be used for repetitive practice swings and/or live hitting practice. Repetitive swinging of the bat 12 with the knuckles and wrists properly aligned enables the player to develop muscle memory and physical memory of the proper alignment and proper grip technique such that the player can effectively duplicate the proper alignment and grip mechanics during a game situation, in which the grip aid device 10 may be prohibited by the rules of the game.
