Abstract

A baseball bat handle grip has an inside surface and an outside surface configured into a tubular body. A top portion houses a plurality of finger channels and finger ridges. A back end of the grip is concave and covers convex interior surfaces of a baseball bat knob when the grip is mounted onto the bat. Two longitudinal edges are parallel to each other and are positioned on a bottom portion of the grip to expose a portion of the baseball bat handle when mounted on the bat. The longitudinal edges are tapered to conform to the curved aspects of the bat handle. To remove the grip, a user's thumbs are inserted into two opposing cut-out grooves on a front end of the grip and pushes the grip up and off the bat handle.

Description

    BACKGROUND
  • This disclosure relates to sports equipment and more specifically to baseball bats and softball bats.
  • Currently, baseball bat handle grips, and sports equipment handle grips in general, are disclosed that encourage athletes to grip a handle for more efficient striking of game balls. The current grips ignore the fact that children and young adults who lack lower arm and hand strength are not able to utilize these grips because the current grips are designed for mature athletes with well-developed arm muscles. Several currently used devices permit the user to actually move the grips, rotating their hands to slide the device into a more comfortable position. Unfortunately, a more comfortable position causes the hitter to resume the same bad habits that these grips are designed to remedy.
  • Thus, an unaddressed need exists in the industry to address these deficiencies and inadequacies.
  • SUMMARY
  • The present invention meets this need by producing a baseball bat handle grip that is easily mounted and removed from a baseball bat handle on bats designed for youth and young adults. The grip does not rotate once installed nor does it slip or slide on the bat. The baseball bat handle grip disclosed herein, unlike other devices, is mountable by locating a terminal end portion of the grip and positioning it flush with an interior surface of a knob of the bat. Removal of the grip from the baseball bat handle occurs by inserting one's thumbs along thumb grooves located at a front end of the device, applying pressure in an upward direction, and allowing the device to release from the baseball bat handle. The result is a stable, reproducible, effective grip to assure the most consistent effective ball striking.
  • In one embodiment, the device is configured as a tubular body to enclose a portion of a handle of a baseball bat. The device has a top portion and a bottom portion. An inside surface conforms to a handle of the baseball bat when mounted on the handle. An outside surface covers the inside surface. A top portion of the outside surface houses a plurality of finger channels and a plurality of finger ridges. A front end of the device has an indentation with at least one cut-out portion. The cut-out portion is configured to receive a batter's thumb. The front end may show two cut-out portions located on opposing areas of the front end to receive both thumbs. When a user applies pressure on one or both of the cut-out portions, the baseball bat grip releases from the bat. A back end of the baseball bat handle grip has a planar surface that is configured in a concave direction to correspond to the convex shape of inside surfaces along a knob of the bat. A first longitudinal edge and a second longitudinal edge are parallel to each other and are positioned on a bottom portion of the bat when the device is mounted onto the bat. In a preferred embodiment the first and second longitudinal edges are configured to expose a portion of the baseball bat handle.

  • Referring to FIG. 1C and FIG. 2B, the back end 46 a, 46 b of the baseball bat grip 10 has a concave curved planar surface 44. Referring to FIG. 4B, the cross-sectional view shows a portion of the concave curved planar surface 44 that conforms to the shape of the convex aspects of the interior surface 20 of the knob 18 of the bat 12.
  • Referring to FIG. 2C, a first longitudinal edge 36 c and a second longitudinal edge 36 d are parallel to each other and in one preferred embodiment will mount onto the baseball bat handle 16, creating a gap between the first and second parallel edges 36 c, 36 d so that a portion of the baseball bat handle 16 is visible. The longitudinal edges 36 c, 36 d are curved and tapered to conform to the bat handle 16. The tapered longitudinal edges blend into the circular contours of the bat handle 16. Thus, the user does not experience the longitudinal edges are rubbing or abrading any portion of the hands or skin.
  • Referring to FIG. 2A, thumb grooves are located within the connecting pieces 34 a, 34 b at the front end 28 of the device 10. The thumb grooves 34 a, 34 b are curved and are configured to allow the user to insert the thumbs along the curved portions 34 a, 34 b of the connecting pieces when the device 10 is mounted on the baseball bat 12, for ease of removal.
  • How to Make the Device
  • Referring to FIG. 6A and FIG. 6B, in one embodiment, an injection molding process is used to make the inside and outside surfaces 52, 54 as shown. Although the various edges, lines and surfaces of the device 10 are identified herein, the device itself is made as one contiguous piece. In the current injection mold process, there is a male (core) and female (cavity) piece to the mold. The device can be made using either a single shot injection molding process or a dual shot injection mold process. In the single shot injection shot process there are two molds: one for the inside surface 52 material and one for the outside surface 54 material. The dual shot process requires only one mold. The inner layer is poured first, a sleeve within the dual shot machine retracts and the outer layer is added.
  • The preferred embodiment employs Nylon 6/6 available from DuPont® for the inside surface 52. This material provides support and structure for repeated uses. Elvax® 34 a, 34 b, an ethylene vinyl acetate available from DuPont® is a soft, spongy, yet sturdy material selected to coat the outside surface 54. Nylon 6/6 for the inside surface 52 is poured to an approximate uniform thickness of 0.25 inches and Elvax® is poured to an approximate uniform thickness of 0.05 inches for the outside surface 54.
  • Uses and Benefits:
  • Once a ball-striking device makes contact with a ball, success is measured by the distance and direction a ball travels. Optimum ball striking occurs when an athlete's hands are correctly aligned along a handle of a piece of sports' equipment designed to hit the ball. In baseball, a successful swing starts with a proper grip around a baseball bat handle. The proper grip exists when the hands are correctly aligned on the bat in an arrangement known as “knocking knuckles”. Referring to FIG. 5A and FIG. 5B, the phenomenon of knocking knuckles is seen in the straight-line arrangement of the knuckles 48 of both hands when a batter holds the bat. Correct alignment of the hands throughout the swing depends on the hitter being able to maintain contact between the palmar portions of the fingers and hands and the baseball bat handle. More consistent results are seen when an athlete maintains a proper grip from the initiation of the backswing through contact with the ball. Young children and some adults do not have sufficient lower arm strength and hand strength to maintain the proper grip and pressure on the baseball bat handle throughout the entire swing. Inadequate lower arm strength and hand muscle strength do not permit the user to maintain contact between the palm-side portions of the hands and fingers along the entire surface area of the grip. Unlike other devices, enhanced performance occurs when a grip with channels and ridges of sufficient thicknesses allow direct contact between the palm-side portions of the finger surfaces and the grip.
  • Referring to FIG. 5, the correct grip consists of aligning the knocking knuckles 48 of both hands in a straight line while applying a firm but loose grip. The removal and mountable baseball bat grip 10 is placed onto the baseball bat handle 16 by first aligning the back surface 44 located at the terminal portions of the back end 46 a, 46 b with the interior surface 20 of the knob 18 of the bat 12. By mounting the baseball bat handle grip 10 so that the back surface 44 is in direct, contiguous contact with the knob 18 of the bat 12, the device will not slip and slide, providing stability to ensure consistent swing patterns by the user. Further, the back surface 44 of the device 10 is configured so that the device 10 is flush with the knob 18.
  • The baseball bat handle grip 10 solves many problems. It allows young hitters to instantly align their hands properly while applying the correct amount of pressure to create the ideal grip. It also helps to create muscle memory for the hitter allowing them to develop the proper grip for future success. The baseball bat handle grip 10 also significantly reduces bat sting, allowing the hitter the confidence to continue swinging the bat without fear of hurting their hands. The present device enhances the reduction of bat sting due to the soft cushion effect of a number of the materials in preferred embodiments that are selected for the outer surface 40.
  • The baseball bat handle grip 10 will increase the likelihood that the young batter will make contact more often. This increases confidence and this keeps the young player more engaged with the sport. Giving young hitters more confidence to keep swinging the bat allows them to improve faster by increasing their repetitions in practice.
  • The baseball bat handle grip 10 will significantly free up time for the coach allowing them to spend more time on the other nuances of hitting instruction like proper weight transfer and hip rotation. This will allow more players to improve at greater rates. The baseball bat handle grip 10 can also be used as a training aid or warm up tool for older, more experienced players. Older players can quickly get back up to speed after long layoffs from playing other sports. By simply using the device it will help bring back the muscle memory quickly, getting them up to speed quickly eliminating extra time figuring out their swing. As a warm up tool it will reinforce the muscle memory, increasing their chances of making contact.
  • The baseball bat handle grip 10 is universal. It fits on all youth baseball and softball bats and over bat handles to which tape has been added. When players change bats they simply remove the baseball bat handle grip 10 from their old bat and put it on their new bat. The baseball bat handle grip may be used by right or left hand hitters with no need to adjust the device.
  • Very importantly, the baseball bat handle grip 10 is personalized for each player. Out of the package the device is pre channeled, allowing the player to instantly know where to place their fingers. The rubber material has some give to it allowing the batter to personalize their grip imprint, making each baseball bat handle grip 10 specific to that batter.
  • The uses and benefits disclosed herein have previously not been appreciated with the grip devices currently in the marketplace. Although the device is used here in relation to a baseball bat, aspects of this device may be modified for use on handles in additional sports including golf, tennis, and lacrosse.
