Description

本発明は、卓球練習器具に関する。      The present invention relates to a table tennis training apparatus.

卓球練習機は、練習をする人が卓球台を挟んだ反対側に設置して行なうものがある（例えば特許文献１参照）。これらは、仮想相手が打球したように練習者に向けてボールを送り出す練習機であり、実戦さながらの上回転・下回転・横回転等のあらゆるボールの打球練習や、身体を移動してから打球するフットワークの練習が可能である。また、１人で行う練習器具もある（例えば特許文献２や特許文献３や特許文献４参照）。  Some table tennis training machines are installed on the opposite side of a table tennis table by a practitioner (see, for example, Patent Document 1). These are practice machines that send the ball toward the trainee as if the virtual opponent had hit the ball. It is possible to practice footwork. There are also practice tools that are performed by one person (see, for example, Patent Document 2, Patent Document 3, and Patent Document 4).

特公昭６３−００９８７１  JP-B 63-009871 実登３０９７８２４  Actual climbing 3097824 実開平０４−０４７４７５  Japanese Utility Model 04-04475 実開平０１−０２８６７５  Japanese Utility Model Hei 01-028675

以上のような卓球練習機は、実戦練習として優れているが、卓球台や練習機を置く場所や練習機を動かす動力や多数のボールやネット等が必要だった。安価にして１人で簡便に練習が出来ない。また、１人で簡便に、停止しているボールを打つ練習器具もあるが、打球ボールの位置の復元方法や打球感覚を掴む手段として、錘やスプリングバネやゴム等を使用していて、板バネを利用したものが無かった。  The table tennis training machine as described above is excellent for practical training, but it requires a table tennis table, a place for the training machine, power to move the training machine, and a large number of balls and nets. It is cheap and one person cannot practice easily. In addition, there is a practice tool for hitting a ball that is stopped easily by one person, but a weight, a spring spring, rubber or the like is used as a method for restoring the position of the hit ball or for grasping the hit ball feeling. There was nothing using springs.

１人で安価で簡便に練習出来る事を目的に、卓球台や動力は使わずに、停止ボールを打つ事にし、打球ボールの位置の復元と打球感覚を掴む手段としては、帯状の板バネ（以下板バネとする）を利用する。  For the purpose of being able to practice cheaply and easily by one person, a stop ball is hit without using a ping-pong table or power, and as a means of restoring the hit ball position and grasping the hit ball feeling, a strip-shaped leaf spring ( (Hereinafter referred to as a leaf spring).

板バネの先端にボールを設け、板バネの下部を板バネ下部保持具で固定した打球構造部を台のポストに固定して、台をボールが身体の前に来ている状態にして置いて、打球練習とフットワーク練習をする。  Place the ball at the tip of the leaf spring, fix the ball striking structure with the lower part of the leaf spring fixed by the leaf spring lower holder to the post on the stand, and place the stand with the ball in front of your body. , Practice ball practice and footwork.

板バネの復元力を利用するので、ボールと板バネは、打球した方向に振れるように台に取付ける。  Since the restoring force of the leaf spring is used, the ball and the leaf spring are attached to the base so as to swing in the hit direction.

打球感覚が掴めるように、板バネの先端のボールは、上下回転が可能で上下動が出来るようにし、かつ、上下動した時にボールが板バネの先端から脱落しないようにする。  The ball at the tip of the leaf spring can be rotated up and down and can move up and down so that the ball hitting feel can be grasped, and the ball does not fall off from the tip of the leaf spring when moved up and down.

振れ幅が調整出来るように、板バネの下端部の保持具は、上部は下部より広くし、かつ、板バネの復元力の微調整用の板バネも挟めるようにする。  The holder at the lower end of the leaf spring is wider than the lower portion so that the swing width can be adjusted, and a leaf spring for fine adjustment of the restoring force of the leaf spring is also sandwiched.

上下回転や横回転の打球練習を可能にする為、板バネの角度を変えられるように板バネの下端部の保持具を上下位置や角度調整が可能な調整板に固定し、それを、練習に適した角度になるように台のポストに取付ける。  In order to make it possible to practice ball hitting in vertical and horizontal rotations, the holder at the lower end of the leaf spring is fixed to an adjustment plate that can be adjusted in the vertical position and angle so that the angle of the leaf spring can be changed. Attach it to the pedestal post at an angle suitable for

台は、持ち運び可能で倒れないような構造としてポストを設け、ポストには、身長に合うように、又、高い球や低い球の打球練習が出来るように、又、前項の調整板を取付けられるような構造にする。  The stand is designed to be portable and will not fall down, and the post can be fitted with the adjustment plate described in the previous section so that it can fit the height and can practice hitting high and low balls. Make a structure like this.

本発明は、板バネの復元力により、打球ボールの位置の復元を継続して可能とし、かつ、ボールが上下動出来るので実戦で打球した時の感覚が掴める。  According to the present invention, it is possible to continuously restore the position of the hit ball by the restoring force of the leaf spring, and since the ball can move up and down, the sense of hitting in actual battle can be grasped.

本発明は、板バネの復元力により、打球後に前後する動きのあるボールを打球する練習も出来る。  The present invention can also practice hitting a ball that moves back and forth after the ball is hit by the restoring force of the leaf spring.

本発明は、卓球台を置けない狭い場所でも動力源が無くても、打球練習やフットワーク練習が、屋外でもリビングルームでも和室でも１人で出来る。  In the present invention, even in a narrow place where a table tennis table cannot be placed, even if there is no power source, the practice of hitting and practicing footwork can be performed by one person outdoors, in the living room, or in the Japanese room.

本発明は、打球するボールの前後左右上下位置が固定出来るので、ボールと打球時の足の位置を調整する事で正しいフォームが掴める事から、その打球練習を繰返す事で正しいフォームを身に付けられる。  Since the present invention can fix the front / rear / left / right / up / down positions of the ball to be hit, the correct form can be grasped by adjusting the position of the ball and the foot at the time of hitting, and the correct form can be acquired by repeating the hitting practice. It is done.

本発明は、打球するボールの位置が固定出来る事から、１〜２歩離れた場所にいて移動してから打球するフットワークの練習が出来る。  In the present invention, since the position of the ball to be hit can be fixed, it is possible to practice footwork to hit the ball after moving at a place one or two steps away.

本発明は、打球時のボールの回転がその場で見られるので、打球の回転速度の変化の練習が容易に出来る。  In the present invention, since the rotation of the ball at the time of hitting can be seen on the spot, the practice of changing the rotation speed of the hitting ball can be easily performed.

本発明は、打球するボールの位置が固定出来る事から、ボールがラケットに当たる瞬間を見られるので、実戦に於いて打球する時にボールから目を離さない練習が出来る。  In the present invention, since the position of the ball to be hit can be fixed, it is possible to see the moment when the ball hits the racket, so that it is possible to practice keeping an eye on the ball when hitting in actual battle.

本発明は、打球するボールの位置が固定出来る事から、ラケットがボールに当たる迄の、腕や足や胴体や頭の動き、そして目の動きをスローモーションのように分解しながら練習が出来る。  Since the position of the ball to be hit can be fixed, the present invention can be practiced while disassembling the movements of the arms, legs, torso, head, and eyes until the racket hits the ball like slow motion.
