Description

  The present invention relates to an auxiliary tool for correcting the movement of fingers and wrists when catching a baseball so that the baseball can be captured correctly.

In baseball, catchers and infielders must catch a grounder (goro) and then send it to the hand that quickly throws the ball.
In order to perform this series of operations smoothly and quickly, it is important to first capture the ball with the correct operation, and if this operation cannot be performed correctly and faithfully, the hand that sends the captured ball When it comes back up, useless action enters, which causes the pitching to be delayed by one tempo.

In order to faithfully perform the correct catching operation, it is important to use the fingers and wrists to catch the ball.
The use of the above fingers and wrists is not to hold the ball with the ball catching device, but to place the ball in the ball catching device with the feeling of catching the ball with the palm of the hand, and instantly the first and second joints of the fingers other than the thumb In addition, the movement of the wrist is used to change the catching angle to kill the momentum of the ball. By wearing this action, the transition to the next pitching action can be performed reliably and instantaneously.

  The above-mentioned catching action is not always easy to wear correctly even if it can be understood by the head, and baseball leaders instruct players to wear the above catching action. However, there are many players to teach, so it was difficult for each player to get the correct catching action.

  The problem of the present invention is that anyone can easily correct the movement of fingers and wrists at the time of catching simply by putting it on the hand, and thereby catching the ball with the correct catching action, that is, sensing the ball with the palm. Auxiliary tool that can be put in the tool and instantly put on the action of killing the momentum of the ball by changing the catching angle using the first and second joints of the fingers other than the thumb and the action of the wrist Is to provide.

As a result of intensive studies to solve the above problems, the present inventor,
In order to prevent the wrist from bending outward, an auxiliary plate that occupies at least the center of the back of the hand extending from the back of the hand to the wrist in contact with the back of the hand,
In order to prevent the third joint of the fingers other than the thumb from bending, at least the palm extending from the palm to the third joint and the second joint of the index finger, middle finger and ring finger in contact with the palm. Anyone will be able to practice catching a ball by wearing two auxiliary plates that occupy the center of the two and an auxiliary tool that attaches these auxiliary plates and attaches them to the hand. It can easily correct the movement of fingers and wrists at the time of catching easily, so that the ball is placed in the catching tool as if it were caught by the palm, and the first and second joints of the fingers other than the thumb and the wrist instantly The present invention has been completed by finding that it is possible to easily acquire the action of killing the momentum of the ball by changing the catching angle using the action of.

That is, the present invention
[1] An auxiliary tool for correcting the movement of fingers and wrists when catching a baseball,
1) Auxiliary plate that touches the back of the hand, extending from the back of the hand to the wrist, covering at least the center of the back of the hand and the joint of the wrist, thereby preventing the wrist from curling outwardly, 2) An auxiliary plate in contact with the palm, extending from the palm to the third joint (MP joint) and the second joint (PIP joint) of the three fingers of the index finger, middle finger and ring finger, at least the center of the palm and the index finger, An auxiliary plate 2 that covers the third joint (MP joint) of the three fingers of the middle finger and ring finger, thereby preventing the fingers from bending at the third joint (MP joint) of the fingers other than the thumb, and 3) An auxiliary tool comprising an auxiliary plate 1 and the auxiliary plate 2 attached to each other and a joint 3 for attaching to the hand;
[2] The auxiliary tool according to [1], wherein the joint portion 3 is formed of an elastic member that covers a part of or the entire hand.
[3] The auxiliary tool according to [1], wherein the joint portion 3 is a glove-shaped member that covers the entire hand other than the finger portion.
[4] The auxiliary tool according to [1], wherein the joint portion 3 is a glove-shaped member that covers the entire hand including the finger portion.
It is about.

According to the present invention, anyone can easily correct the finger and wrist movements at the time of catching simply by wearing it on the hand, and thereby correct the catching action, that is, the ball is caught in the catching tool with a sense of catching the ball with the palm. Provided with an auxiliary tool that can easily wear the action of killing the momentum of the ball by changing the catching angle using the movements of the first and second joints of the fingers other than the thumb and the wrist instantly Is done.
As the assisting device of the present invention wears this and increases the number of catching exercises, the finger and wrist can move correctly when catching the ball. The probability of achieving the operation of holding can be increased.
Therefore, the assisting tool of the present invention can play an important role in the training of future baseball players.
Furthermore, the assisting device of the present invention conforms to the official baseball rules without violating the provisions of the device, so that it can be used in official games hosted by the Japan Professional Baseball Organization or the Japan High School Baseball Federation. Is something that can be done.
Therefore, the auxiliary tool of the present invention can play an important role in practical use such as various official games of baseball.
