Abstract

PROBLEM TO BE SOLVED: To provide a training device for shadow pitching which has the same dimension and weight as those of an actual baseball, and is formed by stitching a cut edge of one hemispherical part of the ball in a halved state to fingertips of a two-finger glove formed of only a forefinger and a middle finger, allowing a user to train the pitching using the training device in a form closer to the actual play than conventional manners of training with the bare hand or using a towel, applying a load to the shoulder, the arm, the wrist, and the fingers, and being effective for strengthening muscles.SOLUTION: The pitching training device has the same dimension and weight as those of the actual baseball, is formed by stitching one of hemispherical parts that form the ball 2 in a halved state and are fitted to each other to the fingertips of the two-finger glove 1 formed of only the forefinger and the middle finger. When the ball is released in the pitching training, the other halved part is thrown forward. The two halved parts are connected to each other with a strap-like ribbon stored inside the ball.

Description

本発明はシャドーピッチング用練習具に関するものである。さらに詳しくは、人指し指および中指の二本のみが手首部分に繋がった２指手袋に、二つ割り状態のボールの片方の半球部分が縫い付けられ、半球部分は互いに嵌りあい、かつ半球部分相互がボールの内側にしまわれた帯状のリボンで繋がったボールとからなるものである。
そしてこの二つ割り状態のボールを公認の野球ボールと同じ大きさ、重さとすることで、このボールを人指し指、中指および親指の３本で握って、実際に前方へ投げて投球練習をすることで、適当に肩や腕、手首、指先に負荷が掛かり、より高い投球練習効果を得ることができる練習具である。 The present invention relates to a practice tool for shadow pitching. More specifically, a two-finger glove in which only two forefinger and middle finger are connected to the wrist part is sewn with one hemispherical part of the split ball, the hemispherical parts fit together, and the hemispherical parts are It consists of balls connected by a ribbon of ribbon that is hidden inside.
And by making this split ball the same size and weight as a certified baseball ball, grasping this ball with three forefinger, middle finger and thumb, actually throwing forward and practicing throwing, It is a practice tool that can properly apply a load to the shoulders, arms, wrists, and fingertips and achieve a higher pitching practice effect.

これまで、シャドーピッチングの練習をする時は素手か、タオル又はタオルの様な布をボールの代わりに丸めて手で握り、これを前方に放つことでシャドーピッチングを行っていた。そのためシャドーピッチングの練習時に本来期待できる肩や腕、手首、指先に適度な負荷が掛かるということは殆ど期待できないか、あるいは期待できてもその負荷効果は小さかった。 In the past, when practicing shadow pitching, shadow pitching was performed by rolling a bare towel or a towel-like cloth instead of a ball and holding it with your hand, and releasing it forward. Therefore, it can hardly be expected that a moderate load is applied to the shoulder, arm, wrist, and fingertip that can be originally expected when practicing shadow pitching, or even if it can be expected, the load effect is small.

本発明のシャドーピッチング用練習具は、上記で述べた構成を備えていて、二つ割り状態のボールの片方の半球部分が２指手袋の人指し指および中指の先端に縫い付けられ、かつ半球部分は互いに嵌りあい、半球部分相互はボール内側にしまわれた帯状のリボンで繋がったボールとからなり、このボールを公認の野球ボールと同じ大きさ、重さも同じとしている。したがってこのボールを人指し指、中指および親指で握って、実際に前方へ投げて投球練習をすることで、肩や腕、手首、指先に適度な負荷が掛かり、より投球の実態に近い投球練習をすることで実戦投球の効果を得ることができるものである。 JP2001-218881
The practice tool for shadow pitching according to the present invention has the configuration described above, and one hemispherical portion of the split ball is sewn to the tip of the index finger and middle finger of the two-finger glove, and the hemispherical portions fit into each other. On the other hand, the hemispherical parts are composed of balls connected by a ribbon-like ribbon enclosed inside the ball, and this ball has the same size and weight as an official baseball. Therefore, by holding this ball with your index finger, middle finger and thumb, and throwing it forward, you can practice throwing with a moderate load on your shoulders, arms, wrists, and fingertips. In this way, it is possible to obtain the effect of actual pitching.

本発明は、上記のこれまでのシャドーピッチング練習具では、投球練習時に指先にほとんど負荷がかからないという課題を解決したピッチング用練習具を提供することを主たる目的としたものである。 The main object of the present invention is to provide a pitching practice tool that solves the problem that the fingertip is hardly loaded during pitching practice in the above-described conventional shadow pitching practice tool.

本発明によれば、人差し指、中指からなる２指手袋の各指先端部分に二つ割りのボールの片方の半球部分を強力な糸で縫い付けて固定し、その二つ割りのボールを公認の野球ボールと同じ大きさ、重さとし、なおかつ二つの半球部分の内側に、ボールをリリース時に放射力が作用して片方の半球部分が他方のそれとの嵌め込みを解かれて開き、この嵌め込みを解かれた半球部分がボールの内部に収められていた帯状のリボンを引き連れて前方に放出される。この投球練習時に肩、腕、手首、指先に適度な負荷を伴うことでより、実戦投球に近い高い練習効果が得られる。 According to the present invention, one hemispherical portion of a split ball is sewn with a strong thread to each finger tip portion of a two-finger glove consisting of an index finger and a middle finger, and the split ball is the same as an official baseball ball. Size, weight, and inside of the two hemispherical parts, when the ball is released, radiation force is applied and one hemispherical part is unfitted and opened with the other hemispherical part. The belt-shaped ribbon stored in the ball is drawn forward and released. When this pitching practice is carried out, it is possible to obtain a high practice effect that is close to that of actual pitching by having a moderate load on the shoulders, arms, wrists, and fingertips.

さらに公認の野球ボールと同じ大きさ、重さの二つ割り半球体からなるボールを握ってシャドーピッチングをすることで、投球のイメージ効果が高い練習ができる。 Furthermore, by holding a ball consisting of a half hemisphere that is the same size and weight as a certified baseball, you can practice pitching with a high image effect.

本発明では公認の野球ボールと同じ大きさ、重さの二つ割りの、球形に嵌り合った片方の半球部分の割ぎわを２指手袋の人差し指、中指のそれぞれ先端に強力な糸で縫い留めて、２指手袋の指差嵌め込口から手首部分にかけて伸びでた帯状１本の固定紐部分を手首部分にベルトで止めて投球練習時に２指手袋が手から抜け落ちないようにすることで、連続してシャドーピッチングをすることができるようにしたものである。このためボールリリース時にボールには放射力が働き、縫い止めされていない半球部分の片方が帯状のリボンを引き連れて前方に飛ばされ人差し指、中指等に負荷が掛かり、この負荷によって肩、腕、手首等の鍛えられるものである。 In the present invention, a split of one hemispherical part that fits into a sphere in the same size and weight as an official baseball is sewn with a strong thread at the tip of each index finger and middle finger of a two-finger glove, Continuously, the two-finger glove does not fall out of the hand during throwing practice by fastening the belt-like one fixed strap part that stretches from the finger insertion slot to the wrist part of the two-finger glove. This enables shadow pitching. For this reason, radiation force acts on the ball when the ball is released, and one side of the hemispherical part that is not sewn is pulled forward with the belt-shaped ribbon, and the forefinger, middle finger, etc. are loaded. Etc. can be trained.

このシャドーピッチングの練習を投球インターバルや腕の振りの強弱を加減するなどして、より実戦投球に近い形ですることで、今までの素手やタオルを使用してのピッチング練習よりも、より投球練習時の負荷効果がかかった有効な筋力鍛錬ができる練習具を提供できる。 This shadow pitching practice is more like a pitching pitch by adjusting the pitching interval and arm swinging strength, making it more pitching than conventional pitching practice using bare hands and towels. It is possible to provide a practice tool that can exercise strength effectively with the load effect during practice.
