Abstract

[PROBLEMS] When performing throwing training with a wrist and fingers, a fulcrum is created using the other hand, an unnecessary pressure load is avoided on one hand, and the repulsive force is adjusted according to fatigue by adjusting the force of the other hand It can be adjusted to the strength of the arm, and the hand can be repeatedly trained for a long time without unnecessary compression fatigue.
A grip handle, a sub-plate, a spring arm, and a rotating body attached to the tip of the grip bridge bridged between two struts are placed on one hand and the other hand holds the grip handle. The wrist, finger muscle strength, and the pushing force of the other hand are also improved by holding the rotating body with the palm of one hand and repeating the bending and stretching movements with the grip handle as a fulcrum. The sub-plate is devised so that it rotates freely and can be flexibly added according to the surface angle of the arm. By holding the grip handle provided on the column with the other hand and placing the fulcrum of bending and stretching on this grip handle, it is possible to avoid applying unnecessary pressure load on one hand and to adjust the force of the other hand at will To do.

Description

The present invention relates to a training device that simultaneously improves the snapping force and finger muscle strength of the wrist and increases the thrust force of the other hand in order to increase the pitching speed of baseball, softball and the like.
JP2004008349A

This kind of general equipment trains its hands with only one hand. Ideally, arms, wrists, and palms can be bent and stretched in free space, but training with only one hand requires at least two fulcrum points for bending and stretching anywhere on the arm. When the number of repetitions is large or when the training time is long, an unnecessary pressure load is applied to the contact arm portion and wrist portion of the fulcrum, which may cause muscle pain and blood circulation disorder. The throwing training device is intended to allow the gripping handle of the other hand to be a fulcrum so that the compression load of this fulcrum is not applied to the training arm and to enable bending and stretching training for a long time or many times.

The present invention makes a fulcrum using the other hand (Ha) when performing throwing training with the wrist and fingers, avoiding unnecessary pressure load on one hand (Hb), and applying repulsive force to the other hand ( By adjusting the force of Ha), the strength according to the fatigue is arbitrarily adjusted. On the other hand, the hand (Hb) can be continuously trained for a long time without being subjected to unnecessary compression fatigue.

In order to solve the above problems, the present invention is a grip handle attached to the support column (1) and supported by the other hand (Ha), and a one hand provided on the support column (1) at a position below the handle. The spring arm (4) is attached to the upper part of the instrument provided with the sub-plate (3) on the elbow of (Hb), and the rotating body (5) that can be grasped with the other palm is attached to the tip of the spring arm, It is a pitching training tool that enables long-time training using the hand (Ha) as a fulcrum.

(1) Although the spring (4) which has a fixed repulsive force is used for the instrument of Claim 1, by adjusting the force which supports the fulcrum of the other hand (Ha) arbitrarily, one spring (Hb) Without mechanically adjusting the applied force, it can be flexibly extended and repetitively exercised by adjusting it to suit its own power.
(2) Since the grip handle (2) and the auxiliary plate (3) bridged between the support columns according to claim 2 can eliminate the fulcrum acting on one of the hands to be trained, the compression load of the fulcrum is reduced. It can eliminate the causing muscle pain and other injuries. At the same time, the pressing force of the other arm is improved.
(3) The spring described in claim 3 makes it possible to use a leaf spring, a linear spring and other various springs.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a description will be given based on the drawings showing an embodiment of the present invention.

As shown in FIG. 2, a support (1), a gripping hand (2) attached to the support (1) and supported by the other hand (Ha), and one hand (Hb) provided at the lower position thereof An instrument main body is composed of the auxiliary plate (3) next to the elbow, and a spring arm (4) and a rotating body (5) are attached to the upper part of the instrument main body.

  As shown in FIGS. 4 and 5, a cantilever body having a single column is provided, and a spring arm and a rotating body are attached to the upper part.

  A spring arm and a rotating body are similarly attached to an object that is molded and integrated with a reinforced plastic or the like.

The purpose of this idea is to perform wrist and finger strength training for young people who are aiming to be baseball players in a form similar to natural pitching form. Using this device, the wrist and finger muscles are repeatedly bent and trained by using the repulsive force of the device during free time when not practicing at the baseball field (in the home or other free time).

FIG. 1 is a plan view seen from above. FIG. 2 is a front view. FIG. 3 is a side view but shows the association with a hand instrument. FIG. 4 is a plan view of the instrument in the case of a main body having only one column. FIG. 5 is a front view of the instrument in the case of a main body having only one column. Fig. 6 shows an example of an assumption figure when the main body integrated with reinforced plastic is molded.
