とを目的としたテニス練習機に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an object of automatically returning a practice ball only when the practice ball flies in a substantially correct direction when the practice ball is hit in the most natural state. About tennis practice machine.
【０００２】[0002]
【従来の技術】従来、練習ボールを打撃した際、練習ボ

帰するようにしたテニス練習具は色々と提案されている
（例えば特開昭６３−１０９８８２号）。2. Description of the Related Art Conventionally, various types of tennis practice tools have been proposed in which, when a practice ball is hit, the practice ball once flies, then reverses and automatically returns to the position before the hit (for example, (Kaisho 63-109882).

【発明により解決すべき課題】前記従来のテニス練習具
は、飛球方向の如何に拘らず、練習ボールが旧位置へ復
帰するので、プレー時の各種姿勢による打球の方向制御
の可否が不明であった。In the conventional tennis practice tool described above, the practice ball returns to the old position regardless of the flight direction, so it is unclear whether the direction of the hit ball can be controlled by various postures during play. there were.
【０００４】従って方向制御が悪い場合でも良いと思い
勝である反面、テニス練習具による高度の技術の向上は
望むことができない問題点があった。Therefore, even if the directional control is bad, it is good to have it, but on the other hand, there is a problem that it is not possible to expect the improvement of the high-level technique by the tennis practice tool.

るようにして、前記従来の問題点を解決したのである。According to the present invention, however, a pole is attached to one side of a base which is prone to fall against an external force in a direction perpendicular to the direction of flight and a practice ball is attached to the pole via an arm rod. Therefore, if the direction of hitting the practice ball is wrong, the base will fall, and the above-mentioned conventional problems can be solved by making it easy to know whether the hit ball is right or wrong.

る。That is, according to the present invention, the lower end of the pole is rotatably attached to the base on one side of the base, and the base of the arm rod of the practice ball is rotated vertically on the upper end of the pole. The practice ball is attached to the tip of the arm rod so as to be able to move with a small amount of recovery, and the pole is provided with a returning means after falling down and a holding means for standing up at a predetermined angle. It is a tennis practice machine characterized by that. Still another invention is to install a receiving seat at the tip of the arm rod for abutting one side of the practice ball, abut the practice ball, and attach one end of a string diametrically penetrating the practice ball with the outer wall portion of the practice ball, The other end of the cord is characterized in that it is inserted through the arm rod and fixed near the base thereof, and the return means of the pole is installed upright on the other side of the base (opposite to the pole fall). Both ends of the elastic strip are fixed between the holding rod and the lower part of the pole. To describe another invention, the means for holding the standing posture of the pole is as follows. The tension means stretched between the tip of the base (the side where the pole falls) and the upper part of the pole, and the center of the base. It is configured with a reference rod that is planted in the.
The base side of a main rod having a predetermined length is fitted and supported, and the base end of the main rod is supported by an elastic seat attached to the inner lower portion of the base pipe.

ができる。According to the present invention, since the pole can be swung down along the long edge of the slender base, the base can be stably installed depending on whether the direction of the hit ball is correct or not (the angle of deviation from the correct direction). Or you will be prone. Therefore, the quality of the direction of the hit ball can be judged based on the state of the base (not slightly moving, slightly swinging in the direction of the short edge, causing large swing, or falling).

た止具１７に固定する（図４）。1 and 2, an elongated hole 2 is provided on one side of an elongated base 1, and a lower end of a base pipe 3 is inserted into the elongated hole 2 and fixed rotatably by a horizontal support shaft 4. . At the inner lower part of the base pipe 3, a rubber piece 6 and a collar 7 are sequentially stacked on the support shaft 4,
The base end of the main rod 8 inserted into the base pipe 3 is brought into contact with the collar 7 (FIG. 3). The base pipe 3 and the main rod 8 form a pole 5. An arm rod 11 of a practice ball 9 is provided on the upper end of the main rod 8.
The mounting bracket 10 (made of rubber) is fixed, and the base of the arm rod 11 is attached to the bracket 10 by the horizontal pin 12 so as to be vertically rotatable. A tension string 13 is stretched between the upper end of the main rod 8 and the tip side of the arm rod 11. A receiving seat 14 is fixed to the tip of the arm rod 11, and the receiving seat 14 is funnel-shaped and overlaps with the funnel-shaped receiving piece 15 of the practice ball 9 in a sliding contact fit. The receiving piece 15 is in contact with one side of the practice ball 9, and is fixed to the practice ball 9 through one end of an elastic cord 19 via a stopper piece 16. The other end of the elastic cord 19 is the arm. It is inserted through the rod 11, is pulled out from the base of the arm rod 11, and is fixed to a stopper 17 fixed to the base of the arm rod 11 (FIG. 4).

設置してあり、ポール５の傾斜姿勢の基準とする。A mounting piece 21 is fixed to the middle portion of the main rod 8 so that the vertical position of the mounting piece 21 can be adjusted.
And both ends of the string 22 are fixed to the upper surface of the base 1 on the left side (in FIG. 1) to adjust the angle of the pole 5. A reference rod 23 is installed upright on the base near the right edge (FIG. 1) of the elongated hole 2 and serves as a reference for the tilted posture of the pole 5.

できる。First, the training machine is set at the place where the tennis practice is performed. In this case, the inclination of the pole 5 can be adjusted by moving the mounting piece 21 in the direction of the arrow 26 or 27. Further, the inclination of the arm rod 11 can be adjusted by moving the stopper 16 in the direction of the arrow 28 or 29.
【００１５】このようにして、練習ボール９の高さを使
用者の打球高さにする。In this way, the height of the practice ball 9 is set to the hitting height of the user.

ができる。Next, when the practice ball 9 is hit with the racket, the practice ball 9 flies in the direction of the arrow 30, so that the pole 5 rotates about the support shaft 4 in the direction of the arrow 31,
The pole 5 falls to the left in FIG. In this case, when the direction of the flying ball is parallel to the long edge of the base 1, the base 1 is stable, but when the flying direction is biased to the right or left like 9b or 9a in FIG. Lateral force acts on the base 1 and the base 1 falls down. For example, if the tape 33 is stretched in the flight direction, the correctness of the flight direction can be known depending on whether the grounding position of the practice ball 9 is on the tape 33 or outside the tape 33.
【００１７】テニスの練習に際しては、各種方向から駆
け寄って打球するけれども、飛球は常に希望する方向へ
飛ばなければ、高度技術の練習にはならない。When practicing tennis, the player hits the ball by rushing from various directions, but unless he or she always flies in a desired direction, high-tech practice is not possible.

準杆２３で制御されるので、ポール５は旧位置へ正確に
保持されることになる。When the pole 5 falls down as described above,
Because it is pulled in the opposite direction by the elasticity of the elastic strip 20,
The pole 5 rotates in the opposite direction as indicated by the arrow 32 and returns to the old position. In this case, when it is excessively tilted due to inertia, it is controlled by the reference rod 23, so that the pole 5 is accurately held in the old position.
