Abstract

<P>PROBLEM TO BE SOLVED: To provide a practicing machine which enables hitting a ball in a state rested in the air by hardly applying an impact to a racket while it is hard to practice hitting the ball in the state rested in the air with a frame of the racket being an obstacle since the ball is hit at the center of the racket in a case of hitting practice of tennis. <P>SOLUTION: A wire body having stretchability is hung from a distal end of an arm which extends from a post. On the end of the wire body, a tape which is engaged with a fiber on the surface of the ball is attached. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、硬式テニスの打撃練習に関するものである。 The present invention relates to a practice for hitting hard tennis.

衝撃を吸収する装置に固定されたボールを打撃する練習機がある。 There is a training machine that hits a ball fixed to a device that absorbs shock.

特開昭６３−１０９８８２号公報 JP 63-109882 A

野球のバッティング練習ではゴム等で作られた受け台にボールを乗せ、バットでボールを打ち練習することが可能ですが、硬式テニスでは受け台に乗せたボールを打つと、ラケットのガットとフレームが受け台にぶつかり衝撃を受けてしまうので、実現難しく、また固定したボールを打つ練習装置の場合は打撃したボールの軌跡を見ることが出来ないうえ、打撃の衝撃を吸収するため大掛かりな装置が必要である。 In baseball batting practice, it is possible to put a ball on a cradle made of rubber and hit the ball with a bat, but in hard tennis, hitting the ball placed on the cradle, the racket gut and frame Because it hits the cradle and is impacted, it is difficult to realize, and in the case of a practice device that hits a fixed ball, it is not possible to see the trajectory of the hit ball, and a large device is required to absorb the impact of the hit It is.

打ちたいボールの高さ以上である支柱の根元近くに、取り外し可能な複数の安定脚を設け、支柱の一定の高さにスライド可能な留め具を設け、支柱の先端にアームを設け、アームの根元と先端部に伸縮性の線体を通すガイド部を設け、スライド可能な留め具からアームの二つのガイド部を通り、アームの先端から垂らした伸縮性の線体を設け、線体の先端部にテニス硬式ボール表面の繊維に引っかかるテープを取り付ける。
以上の構成からなる硬式テニス練習機である。Near the base of the strut that is higher than the height of the ball you want to hit, provide a number of removable stabilizing legs, a fastener that can slide to a certain height of the strut, an arm at the tip of the strut, Provide a guide part that allows the elastic wire to pass through the base and tip, and provide an elastic wire that passes from the slidable fastener through the two guide parts of the arm and hangs from the tip of the arm. Attach the tape that catches the fiber on the surface of the tennis ball.
This is a tennis training machine with the above configuration.

ラケットのフレームに殆んど衝撃を受けることなく、空中にあるボールを打つことが出来、ボールの軌跡も実際に打った時と近い軌跡を描き飛んでいく。又、打撃の衝撃は打たれたボールに主に伝わるため、衝撃を吸収する装置は必要ない。You can hit the ball in the air with almost no impact on the frame of the racket, and the ball trajectory will follow a trajectory that is close to the actual hit. Further, since the impact of the impact is mainly transmitted to the hit ball, a device for absorbing the impact is not necessary.

本発明の斜視図Perspective view of the present invention

（イ）取り外し可能な複数の安定脚（１）で支えられた支柱（２）の上部にアーム（３）を設ける。
（ロ）支柱（２）とアーム（３）に伸縮性の線体（４）を通すガイド（５）を設ける。
（ハ）支柱（２）にガイド（５）を通った伸縮性の線体（４）の端を取り付けるスライド可能な留め具（６）を設ける。
（ニ）支柱（２）に取り付けられたスライド可能な留め具（６）からガイド（５）を通りアーム（３）の先端から下げられた伸縮性の線体（４）にボール表面の繊維に引っかかるテープ（７）を設ける。
本発明は以上のような構成である。
これを実際に使用するときは、ボール表面の繊維に引っかかるテープ（７）に硬式テニスボール（８）を圧着する。
支柱（２）に取り付けられたスライド可能な留め具（６）を動かし、練習したい高さに硬式テニスボール（８）を合わせ打撃する。
打撃された硬式テニスボール（８）は、打撃された瞬間に、ボール表面の繊維に引っかかるテープ（７）から離れ空中に飛ぶ。(A) An arm (3) is provided on an upper portion of a support (2) supported by a plurality of removable stable legs (1).
(B) A guide (5) is provided through which the stretchable wire (4) is passed through the support (2) and the arm (3).
(C) A slidable fastener (6) for attaching the end of the stretchable wire (4) that has passed the guide (5) to the support (2) is provided.
(D) A stretchable linear body (4) lowered from the tip of the arm (3) through the guide (5) from the slidable fastener (6) attached to the support (2) to the fiber on the ball surface A hooked tape (7) is provided.
The present invention is configured as described above.
When this is actually used, the hard tennis ball (8) is pressure-bonded to the tape (7) caught on the fiber on the ball surface.
The slidable fastener (6) attached to the column (2) is moved, and the hard tennis ball (8) is hit at the height to be practiced.
The hit hard tennis ball (8) leaves the tape (7) caught on the fiber on the surface of the ball and flies into the air at the moment of being hit.

本発明をテニススクールなどで使えば、まだ運動神経が発達していない幼児や、動いているボールだと上手く打てない人もテニスの楽しさを実感できる。
一人でも練習できる。If the present invention is used at a tennis school or the like, an infant who has not yet developed motor nerves or a person who cannot strike well with a moving ball can realize the pleasure of tennis.
You can practice alone.

（１）取り外し可能な複数の安定脚、（２）支柱、（３）アーム、（４）伸縮性の線体、（５）ガイド、（６）スライド可能な留め具（７）ボール表面の繊維に引っかかるテープ、（８）硬式テニスボール(1) Plural removable legs, (2) support, (3) arm, (4) stretchable wire, (5) guide, (6) slidable fastener (7) fiber on ball surface (8) Hard tennis ball
