Description

[0001] ASSISTANCE DEVICE FOR PITCHING TRAINING [0002]

The present invention relates to an auxiliary apparatus for pitching training, and more particularly, to a pitching exercise auxiliary apparatus which provides a load by elastic deformation and restoration of an elastic bar to provide a weight feeling as when throwing a baseball ball, To an auxiliary apparatus for pitching exercise capable of promoting a movement effect.

In general, what baseball players enjoy when they first start playing baseball is how to throw the ball.

But even if you learn how to throw it at the same time, someone throws it well and nobody throws it well.

The reason for this difference is the difference between the first and second person's athletic ability, the second is the difference in physical condition, but the third biggest difference is the difference in whether or not the pitcher learns to throw the ball.

Here, the term "pitching" refers to the upper body motion that actually holds the ball in the entire pitching motion.

The events occurring during pitching of the pitcher can be classified into FC, MER, BR, and MIR as shown in FIG.

FC (Foot Contact) means the moment when the lifted foot landed on the mound, MER (Mzximal External Rotation) means the moment when the shoulder joint is the maximum external rotation, BR (Ball Release) means the moment when the ball falls from the hand , Maximal Internal Rotation (MIR) means the moment when the shoulder joint is maximally internalized.

Also, as shown in FIG. 1, the above-described event can be divided into AC, AA, and AD intervals according to the arm motion of the pitcher.

AC (Arm Cocking) refers to the interval from when the ball throws the ball after the foot contact to the maximum external rotation, AA (Arm Acceleration) refers to the interval from when the ball throwing is released to the maximum external rotation, (Arm Deceleration) refers to the interval from the release of the ball to the time of the maximum internal rotation.

Here, the AC (arm cocking) section of the pitcher is divided into two more specific parts. When the hand is drawn out and the ball is laid down, the arm is raised over the head as it is, and the inertia of the arm and ball is used It will make your arms bend like bow as much as possible behind your head, and only when you reach the maximum you will hit the ball. Then the acceleration range of the arm increases and the ball gets faster and takes a lot of turns.

In order to increase the speed and rotation speed of the ball, it is important to warp the arm when releasing the ball. In the absence of warping of the arm, the distance to transmit the force to the ball is shortened. On the contrary, if the arm can be bent, the distance of transmitting the force to the ball becomes long, so that the force to be transmitted can be increased.

As a related art, there is a pitching exerciser disclosed in Korean Patent Laid-Open Publication No. 10-2009-0119821.

However, the prior art as described above has a problem in that it can not induce bowing of the arm but merely provides air resistance to the wrist.

Accordingly, there is a need for a new technique capable of overcoming the problems of the prior art as described above.
