Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pitching strengthening training device for the purpose of strengthening the training of muscles used in pitching practice by baseball and softball pitchers, catchers, and infielders and outfielders.

[Conventional technology]

Conventionally, this type of muscle strengthening device has been known, for example, as disclosed in Japanese Utility Model Application Publication No. 57-23367.
This is done by holding a grip in your hand and keeping your arm stationary, and using a weight attached to the tip of the grip, you can alternately bend it upwards and downwards using your wrist as a fulcrum. This allows you to do strength training for your wrists.

[Problem to be solved by the invention]

However, according to the above-mentioned conventional example, (a) Although it is possible to train the wrist region by using the device, it is not possible to train other muscles used during pitching.

(b) Therefore, there was an inconvenience that the muscles that cannot be trained must be trained individually using different equipment.

(c) In addition, although using the conventional equipment mentioned above can train muscle strength, it cannot train the explosive power of the muscles that is most necessary for pitching, so it is necessary to use the conventional equipment several thousand times to develop the explosive power of the muscles. , it was necessary to practice throwing with an actual ball tens of thousands of times.

The present invention aims to provide a pitching strengthening training device that solves all of the above-mentioned conventional problems.

[Means to solve the problem]

As a means for solving the above problems, the present invention connects a net-like body to one end of a hollow wrist rest, a shaft is provided horizontally at the connecting portion of the wrist rest and the mesh, and this shaft is A space of an appropriate size is formed between the net-like body and the lower part thereof, and a ball is rotatably inserted through the shaft.

The net-like body can be constructed by knitting a plurality of wires or the like into a mesh shape, or can be constructed by punching a plurality of thin or round holes in a plate of metal or synthetic resin. Further, the shape of the net-like body is not limited to the circular shape as in the embodiment described later, but may be square, fan-shaped, etc., and its material and dimensions are arbitrary. The mesh body can also have a double structure of a front mesh part and a rear mesh part.

It is preferable that the hollow space in the net-like body be formed in a size large enough to allow insertion of a finger for grasping the ball.

Preferably, the ball has the same or similar shape and size as a softball for softball, a hardball for baseball, or a large softball for softball.

[Effect]

According to the present invention having the above configuration, the player inserts his hand into the hollow of the wrist pad and grips the ball with the finger holding the ball during actual pitching through the hollow space of the net-like member. In this state, if you perform a motion similar to actually pitching from the takeback as shown in Figure 4, air resistance will occur in the net in proportion to the arm swing, hip rotation, etc., and this air resistance will be resisted. By performing the pitching motion, the muscles of the arms, shoulders, legs, and hips necessary for pitching can be trained in a well-balanced manner at the same time.

Air resistance increases as the swing of the arm and rotation of the hips during the pitching motion increase, i.e., when a person who can throw a fast ball performs the above pitching motion, and it increases when a person who can only throw a slow ball (a weak person) When a person performs a similar action, the size becomes smaller, so it is possible to perform effective and reasonable training that matches the training person's ability.

If the net-like body has a double structure of a front net-like part and a rear net-like part, air resistance can be further increased.

When the pitching motion approaches the end and enters the follow-through, the wrist rest moves away from the back side of the wrist with the ball as the center, and the net-like body rotates toward the front, as shown in FIG. 5 of the embodiment described later. This prevents the mesh from colliding with other surfaces.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

A is a pitching strengthening training device, and this pitching strengthening training device A includes a wrist support body 1 forming a hollow 1a.
, a net-like body 2 and a ball 3 to be held in hand B, the net-like body 2 is connected to one end of the wrist rest 1 by welding or the like, and a connecting part 2a between the wrist rest 1 and the mesh 2
A shaft 4 is horizontally installed in the
A space 5 large enough to insert a hand is formed between the shaft 4 and the lower part of the shaft 4, and a shaft hole 3a of a ball 3 is rotatably inserted through the shaft 4. 1b is a wrist rest part of the wrist rest body 1.

The mesh body 2 includes a front mesh part 2b and a rear mesh part 2c.
The front mesh part 2b and the rear mesh part 2c are connected and fixed by a metal reinforcing rod 7.

〔Effect of the invention〕

In this invention, a net-like body is connected to one end of a hollow wrist rest, a shaft is provided horizontally at the connecting portion of the wrist rest and the net-like body, and an appropriate size is provided between the shaft and the lower part of the net-like body. Since the shaft has a hollow space and a ball is rotatably inserted through the shaft, the following effects can be obtained.

(1) When you hold the ball in your hand and perform a motion similar to actually pitching, air resistance occurs in the reticular body, and by performing the pitching motion against this air resistance, the arm required for pitching The muscles used for pitching, such as the shoulders, legs, and hips, can be trained in a well-balanced manner at the same time to increase muscle strength, and at the same time, it is possible to develop muscles with explosive power.

(2) Furthermore, the air resistance that acts on the reticular body during the pitching motion increases in proportion to arm tension, hip rotation, etc., and a person who throws a fast ball will experience large air resistance, while a person who throws a fast ball will experience a large amount of air resistance, while a person who throws a fast ball will only experience a large amount of air resistance. Since a small amount of air resistance acts on people who cannot throw (those who are weak), it is possible to perform effective and reasonable training that matches the training person's ability.

(3) Moreover, the air resistance that occurs slows down the pitching speed a little, giving you the leeway to check your own pitching form, and if there are any deficiencies, correct the pitching form yourself. It is also easy.

(4) Furthermore, since the ball held in the hand is the same or similar in shape and size to a softball for softball baseball, a hardball for hardball baseball, or a large ball for softball, it may cause a sense of discomfort to the person training. It is possible to perform training that is more similar to actual pitching without having to give a pitch.

(5) Note that if the net-like body has a double structure of a front net-like part and a rear net-like part, air resistance can be increased.
