The present invention relates to training devices used to help baseball players improve their swing of a baseball bat, and more particularly to such devices which are worn on the hand to adjust the grip on the bat during the swing.
In the sport of baseball, the accuracy and speed of the bat swing is an indispensable factor to player performance in the game, both in terms of imparting a high velocity to the ball as well as control of its direction and flight, i.e. grounder or fly ball. A baseball bat includes a grip held by the player with both the “strong” hand and the “weak” hand, where the strong hand corresponds to the whether the player is right-handed or left-handed. For example, the right hand is the strong hand for a right-handed player, and the weak hand is placed below the strong hand on the grip. Thus, during the swing of the bat, the weak (lower) hand and arm exert a pulling effect on the bat, while the strong (upper) hand and arm exert a pushing effect on the bat. For many players, especially those who are young and inexperienced, there is a tendency to apply too tight a grip with the strong hand, resulting in an exaggerated push of the bat through the swing as the barrel of the bat approaches the baseball. This pushing effect not only works against the pulling effect of the weak hand and arm, but it can also cause inaccurate swings and a decrease in rotational speed of the barrel around the wrist pivot point of the strong hand.
A well-trained batter is often able to overcome the natural tendency to push the bat through the swing by placing greater reliance on the last two fingers of the strong hand, i.e. the pinky and ring finger. Doing so enables the barrel of the bat to more naturally rotate around the strong hand wrist pivot point, which means that the speed of the barrel as it approaches the baseball is the sum of the swing speed itself plus any rotational speed about the strong hand wrist pivot point. In other words, in a proper grip and swing, the barrel of the bat is caused to strike the baseball with greater speed and force than if the bat were pushed through the swing as described above.
Thus, in the training environment, the problem to be solved is to train the player to rely less on the index and middle fingers of the strong hand when grasping the grip of the bat, and to focus the player's attention on the ring and pinky fingers. While there are numerous grip-related devices in the prior art, none appear to address the biomechanics of lifting the index and middle fingers away from the grip of a baseball bat.
U.S. Pat. No. 9,987,534 shows a device used by a batter to connect the pinky finger of the upper hand with the index finger of the lower hand. While there are benefits to maintaining the relative positions of the upper and lower hands on the grip, that device does not include any structure that lifts the index and middle fingers from the grip of the bat.
U.S. Pat. No. 8,602,925 shows a device which is attached to the bat itself that offers a gripping portion for the index finger. It does not teach any benefits of lifting the index finger and middle fingers away from the grip of the bat, and it only improves the basic grip in a more general manner by supporting the index finger alone.
US 2020-0352261 shows a thumb-worn device that tries to address a completely different problem, i.e. bat “sting” and protection of the hand, and it does nothing to raise the index and middle fingers to address the pushing problem described above.
U.S. Pat. No. 6,389,596 shows another thumb-worn device, which is similar in most respects to the device in US 2020-0352261.
U.S. Pat. No. 1,587,287 is a device used in connection with golf clubs, and it includes some structural features to help the golfer improve the grip on the club. Specifically, that device is worn on the hand and has two holes for the pinky and ring fingers along with an extended portion that conforms to the club grip. The stated benefit is that it places the hand in the correct position on the grip, but it does not raise the index and middle fingers, and it does not address the goal of properly swinging the bat to achieve the fastest rotation prior to hitting the ball.
U.S. Pat. No. 4,615,046 shows a “shock absorber” worn on the hand when swinging a golf club. It appears to wrap around the index and middle fingers with Velcro so that those fingers are cushioned when the club strikes the ball. While it may be effective in cushioning the fingers upon impact of the club with the golf ball, it does not lift the index and middle fingers to achieve the goal of relying on the pinky and ring fingers in gripping a baseball bat, and there is no mention of the benefits of raising the fingers by any amount for the purposes of improving the speed of the club or a baseball bat.
As can be seen, the prior art fails to disclose a device which has both the structural and functional features necessary to achieve the training goals stated above. Therefore, the present invention addresses the training problem by providing a device which is worn on the index and middle fingers of the strong hand, lifts the index and middle fingers, and causes the player to rely on the pinky and ring fingers of the strong hand to grasp the grip of the bat during the swing to achieve greater control over the bat and increase the speed of the barrel upon contact with the baseball.
In summary, the present invention is a baseball grip training device for use with a baseball bat, comprising a base adapted to contact a bat grip, wherein the base includes one or more shaped surfaces adapted to receive one or more of an index finger and a middle finger of a user; a retaining member extending from the base shaped to surround one or more of the index finger and the middle finger of the user; and a bat contacting surface adapted to contact the bat grip, wherein the bat contacting surface and the shaped surfaces are separated by a predetermined distance to lift the index finger and the middle finger of the user away from the bat grip sufficient to place greater reliance on the remaining fingers to hold the bat grip during a swing of the bat.
In one embodiment, the retaining member surrounds both the index finger and the middle finger of the user.
In another embodiment, the retaining member surrounds only the index finger of the user.
Preferably, the predetermined distance between the shaped surfaces and the bat contacting surface is approximately one inch.
In another embodiment, the shaped surfaces include pockets formed into the base to receive the ends of the index finger and the middle finger of the user.
In another embodiment, the base includes a plurality of recesses formed into the base and adjacent to the bat contacting surface.
Preferably, the device is constructed from a resilient material.
These and other advantages of the present invention are explained in more detail in the following specification and drawings.
