る筋肉のトレーニング強化を目的とする投球強化
訓練器具に関する。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.
従来からこの種の筋肉強化器具として、例えば
実開昭57−23367号公報のものが知られている。
このものはグリツプを手で持ち腕部分を静止させ
た状態で、グリツプの先端に取着したウエイト

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.
しかるに、上記従来例のものによれば、
(イ) 前記器具を使用することにより手首部分を鍛
えることはできるものの、投球時に使用する他
の筋肉は鍛えることはできないものであつた。
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.
(ロ) そのため、上記鍛えられない筋肉は、夫々別
の器具等を使用して個々の筋肉ごとに鍛えなけ
ればならない不都合があつた。(b) Therefore, there was an inconvenience that the muscles that cannot be trained must be trained individually using different equipment.
(ハ) また、上記従来の器具を使用すると筋肉の筋
力は鍛えられるものの、投球に最も必要な筋肉

筋肉の瞬発力を養うために、数千回、数万回も
の実際にボールを使つた投げ込み練習を行う必
要があつた。(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.
この発明は上記従来の問題点をことごとく解消
する投球強化訓練器具を提供しようとするもので
ある。 The present invention aims to provide a pitching strengthening training device that solves all of the above-mentioned conventional problems.
この発明は、上記課題を解決するための手段と

連接し、手首当て体と網状体の連結部には軸を横
設するとともに、この軸を網状体の下部との間に
適宜大きさの空所を形成し、前記軸にはボールを
回転自在に貫設した構成としてなるものである。
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.
網状体は、複数の針金等を網の目状に編んで構

たは丸穴状の複数の穴を穿設して構成することも
できる。また、網状体の形状は後述する実施例の
如き円形に限らず四角形、扇形などでもよく、そ
の素材や寸法は任意である。網状体は前部網状部
と後部網状部との二重構造とすることもできる。 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.
網状体の空所は、ボールを握るための手指が挿
入できる程度の大きさに形成するとよい。 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.
ボールは、軟式野球用の軟球や硬式野球用の硬
球またはソフトボール用の大型軟球と同一または
類似する形状、大きさのものとするのが好まし
い。 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.
上記構成からなるこの発明によれば、手首当て
体の中空に手を挿入し、網状体の空所を介して実
際の投球時において、ボールを持つ指でボールを
把持する。この状態で第４図のようにテークバツ
クから実際の投球を行うのと同様の動作を行う
と、腕の振り、腰の回転等に比例して網状体に空
気抵抗が生じ、この空気抵抗に抗して投球動作を
行うことによつて、投球に必要な腕、肩、足腰の
筋肉を同時にバランスよく鍛えることができる。
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.
空気抵抗は、投球動作の腕の振り、腰の回転等
が速い程、すなわち速いボールを投げることがで
きる人が上記投球動作を行うと大きくなるし、遅
いボールしか投げることができない人（非力な
人）が同様の動作を行うと小さくなるから、訓練
する人の力量に合つた効果的かつ無理のない訓練
を行うことができる。 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.
網状体は前部網状部と後部網状部との二重構造
とすると、空気抵抗をより増大させることができ
る。 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.
投球動作が終わりに近づきフオロースルーに入
つたとき、後述する実施例の第５図のようにボー
ルを中心に手首当て体は手首の甲側から離れると
ともに、網状体は手前側に回転して、網状体が他
面にぶつかるのを回避できる。 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.
この発明の一実施例を第１図ないし第５図に基

首当て部である。 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.

ら、以下のような効果を有する。
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) ボールを手で持つて実際に投球するのと同様

空気抵抗に抗して投球動作を行うことによつ
て、投球に必要な腕、肩、足腰等の投球に使用
する筋肉を同時にバランスよく鍛えて筋力増強
ができるとともに、瞬発力のある筋肉を養成す
ることができる。(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) また、投球動作時に網状体に作用する空気抵

かつ無理のない訓練を行うことができる。(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) しかも、発生する空気抵抗によつて、ピツチ

ームを自分自身で矯正することも容易である。(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) さらに、手で持つボールは軟式野球用の軟球

ことができる。(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) なお、網状体は前部網状部と後部網状部との
二重構造とすると、空気抵抗を大きくすること
ができる。(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.
