Abstract

<P>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. <P>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. <P>COPYRIGHT: (C)2013,JPO&amp;INPIT

Description

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.

  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.

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.

  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.

  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.

 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.

  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.

  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.

It is the figure by which the fingertip part of the 2 finger glove was sewn on to the hemisphere part of one side of a ball. It is the figure which grasped the ball | bowl through the finger | toe to 2 finger gloves. FIG. 5 is a view in which a ball is broken into two by a pitching operation, and one hemispherical portion released forward is connected by a belt-like ribbon. It is a figure at the time of pitching completion in the state just before the ribbon has extended completely.

 Hereinafter, a shadow pitching practice tool according to an embodiment of the present invention will be described with reference to FIGS.

   FIG. 1 is a view in which one hemispherical portion of a ball is sewn with a strong thread on the tip of a fingertip of a two-finger glove 1 having only an index finger and a middle finger. In FIG. 2, reference numeral 2 denotes a ball in which a half hemispherical portion is fitted, and a split line of the gripped outer hemispherical portion 2 a is sewn to the tip of a fingertip of a two-finger glove. FIG. 2 is a diagram showing a state immediately before the shadow pitching is performed by grasping the ball with the three fingers of the practitioner's dominant hand, here, the index finger, the middle finger and the thumb 6 of the right hand wearing a two-finger glove.

  FIG. 3 shows a state in which one hemisphere 2b of the ball jumps forward away from the other hemisphere 2a when the ball for pitching practice is released. FIG. 3 also shows a state in which one belt-like fixed string portion 3 extending from each finger insertion port of the index finger and the middle finger to the wrist portion is fixed to the wrist portion 4 with the belt 5. The hemisphere 2b that protrudes forward and the ribbon 7 are connected to the inner center of the other hemisphere 2a that is connected to the fingertip in order to apply a load to the fingertip or wrist. FIG. 4 is a view showing a state immediately before the hemisphere 2b is released forward after the ball is released and the belt-like ribbon 7 is fully extended accordingly.
