【考案の詳細な説明】
（産業上の利用分野）
本考案は両端が支持された紐体に取り付けられ
たボールをラケツトで打つことにより、テニスの
ストローク等の練習を行ない得るようにしたテニ
ス練習具に関する。[Detailed description of the invention] (Field of industrial application) This invention is a tennis practice that allows players to practice tennis strokes by hitting a ball attached to a string with both ends supported with a racket. Regarding ingredients.
（従来の技術）
最近、テニスブームと呼ばれるようにテニス人
口が増えつつあり、これにともなつてテニスコー
トも各所に建設されつつある。しかしながらテニ
ス人口の急激な増加にテニスコートの増築が間に
合わず、このため例えばテニススクールなどでは
練習生があふれ、ストローク等の練習を十分に行
なうことができないというのが現状である。(Prior Art) Recently, the number of people playing tennis has been increasing, which is called a tennis boom, and along with this, tennis courts are being constructed in various places. However, the expansion of tennis courts has not kept pace with the rapid increase in the number of tennis players, and as a result, the current situation is that, for example, tennis schools are overflowing with trainees, making it difficult to sufficiently practice strokes and the like.
そこで実際にコートに出なくとも、正しいフオ
ーム、ストローク等を体得し得るようにした様々
なテニスの練習具が提案されている。 Therefore, various tennis practice tools have been proposed that allow players to learn correct form, strokes, etc. without actually going out on the court.
（考案が解決しようとする問題点）
しかしながら、これらのテニス練習具はボール
を取り付けた紐体を直接支持枠体に取り付けると
いう構造のものが多く、その結果ボールを打つた
瞬間、ボールの反発力以外の抵抗（紐等を含む装
置抵抗）を感じ、本来のストロークにおける打球
感触が得難く、又、ラケツトがボールを取り付け
た紐にからみ易いためテニスに重要なフオロース
ルーを習得し難く、更には一般のグランドストロ
ークはラケツトをやや下方から上方に振り抜くた
め、ボールを取り付けた紐体に加わる負荷がボー
ルの上下で異なり、紐体の寿命が短くなる等の問
題があつた。(Problem that the invention aims to solve) However, many of these tennis practice devices have a structure in which the string to which the ball is attached is directly attached to the support frame, and as a result, the moment the ball is hit, the repulsive force of the ball is reduced. This makes it difficult to get the feel of the ball during the original stroke, and it is difficult to learn follow-through, which is important for tennis, because the racket easily gets tangled with the string to which the ball is attached. In a general ground stroke, the racket is swung from slightly downward to upward, so the load applied to the string to which the ball is attached differs between above and below the ball, resulting in problems such as shortening the life of the string.
そこで本考案の目的は、ストローク本来の打球
感触が得られ、フオロースルーの練習も十分に行
え、且つコンパクトで耐久性に優れたテニス練習
用具を提供するにある。 Therefore, an object of the present invention is to provide a tennis practice tool that is compact and has excellent durability, which allows the golfer to feel the ball hitting the ball as it should be during a stroke, allows sufficient follow-through practice, and is compact and durable.

ープ３に滑動自在に取り付けてなる。(Means for Solving the Problems) In order to solve the above problems, the present invention provides strings 5,
A support frame body 2 having mounting portions 11, 12, and 13 of 3 at positions corresponding to respective vertices of a triangular front shape.
are provided, and the three attachment parts 11, 1 of this support body 2 are provided.
The slide rope 3 is stretched between two of the attachment parts 12 and 13, and one end of the string 5 inserted through the ball 4 is attached to the remaining attachment part 11 via a tension adjustment member, and the other end is attached to the other attachment part 11. The end is slidably attached to the slide rope 3.
（作用）
上記問題点を解決するための手段は次のように
作用する。(Operation) The means for solving the above problem operates as follows.
ボール４に挿通した紐体５の一端がスライドロ
ープ３に滑動自在に取り付けられるため、ボール
４を打つた瞬間、紐体５の一端はスライドロープ
３に沿つて滑動する。このためボール４の反発力
以外の抵抗を小さくし得、ラケツトの振り抜きが
容易となり、更に打球後のボール４の慣性力をボ
ール４上下に均一に分配することができる。 Since one end of the string 5 inserted through the ball 4 is slidably attached to the slide rope 3, the one end of the string 5 slides along the slide rope 3 at the moment the ball 4 is hit. Therefore, the resistance other than the repulsive force of the ball 4 can be reduced, the racket can be easily swung, and the inertial force of the ball 4 after hitting can be evenly distributed above and below the ball 4.

The through hole 30 of the ball 4 is opened to the same diameter or slightly smaller than the diameter of the string 5, and can be separated from the ball 4 (not shown in this case) or fixed with a tightening rubber ring stopper 26 connected with a thin wall 25, or fixed with a tightening rubber ring stopper 26 connected to the ball 4 by a thin wall 25. Change the height (position). Note that this method of attaching the ball is just one example, and although not shown, rubber rings or the like may be attached to both ends of the ball, and the ball may be attached by inserting a string through the rubber rings.
（考案の効果）
以上の説明から明らかな如く本考案によれば次
の効果を生ずる。(Effects of the invention) As is clear from the above explanation, the invention produces the following effects.
第１に支持枠体はパイプ部材から成る正面形状
が略三角形で突つ張り構造としたため、構造体の
鋼性が高く振動エネルギーがこの枠体に吸収され
るとともに外部応力が分散され、安定性が高く、
軽量、小型化が容易である。従つてまた地面コン
クリート面等のセツテイング条件によらずセツト
が容易である。 First, the support frame is made of pipe members and has an approximately triangular front shape with a tension structure, so the structure has high steel properties and vibration energy is absorbed by the frame, and external stress is dispersed, resulting in stability. is high;
Light weight and easy to downsize. Therefore, it is easy to set regardless of setting conditions such as the concrete surface of the ground.
第２にボールを取り付けた紐体はスライドロー
プに滑動自在に取り付けられるとともに、このス
ライドロープはその両端が枠体の取付部にやはり
滑動自在に取り付けられるため、ボールを打つた
瞬間におけるボールの反発力以外の抵抗を最小限
に抑制することができ、又ラケツトが紐体にから
むことがないためラケツトの振り抜きが容易とな
り、フオロースルーの練習を十分に行うことがで
きる。更にボールの慣性力をボールの上下の紐体
に均一に分散させることができ紐体の耐久性をよ
くすることができる。 Second, the string to which the ball is attached is slidably attached to the slide rope, and both ends of this slide rope are also slidably attached to the attachment parts of the frame, so the ball rebounds at the moment the ball is hit. Resistance other than force can be suppressed to a minimum, and since the racket does not get entangled with the string, it becomes easy to swing the racket out, and it is possible to sufficiently practice follow-through. Furthermore, the inertial force of the ball can be evenly distributed to the strings above and below the ball, and the durability of the strings can be improved.
第３に紐体は芯ゴムと繊維織紐とからなり、両
者の弾性特性の合成が打撃球の慣性吸収を滑らか
に行い、ボールの慣性を弱めるとともに、繊維織
紐の特性で必要以上ボールが飛び出すのを抑制で
き、この結果連続打撃練習を容易に行うことが可
能である。 Thirdly, the string is made of a core rubber and a woven fiber string, and the combination of the elastic properties of both smoothly absorbs the inertia of the batted ball, weakening the inertia of the ball, and the characteristics of the woven fiber string allow the ball to be used more than necessary. It is possible to prevent the ball from flying out, and as a result, it is possible to easily perform continuous batting practice.
第４に本実施例ではボールの位置（高さ）を自
由に変更できるようにしたため、子供から大人ま
で体格差によらず同様な練習を行うことができ

の変更をすることができる。 Fourthly, in this embodiment, since the position (height) of the ball can be changed freely, everyone from children to adults can practice in the same way regardless of their physical differences. Furthermore, the tension of the string can be changed using the tension adjustment member of the string, thereby making it possible to equivalently change the quality of the sphere.
尚、本考案はテニス練習具としたがテニス以外
の練習具、例えば野球ボールを取り付けた打撃練
習具、あるいはパンチボールを取り付けたボクシ
ング練習具等としても十分に使用可能である。 Although the present invention is a tennis practice tool, it can also be used as a practice tool other than tennis, such as a batting practice tool to which a baseball is attached, or a boxing practice tool to which a punch ball is attached.
