Description
【発明の詳細な説明】 ［発明の利用分野］ 本発明はテニス競技に用いるテニスラケットに関する。[Detailed description of the invention] [Field of application of the invention] The present invention relates to a tennis racket used in tennis competitions.
［背景技術］

きくする役目を有する。[Background Art] A tennis racket is composed of a gut, a frame having a gut opening and a handle. The gut, which is stretched over the frame when the ball is hit, flexes and accumulates energy, which serves to increase the elasticity of the tennis ball as well as the repulsive force of the tennis ball.
ところが従来のテニスラケットでは、打球時にボールが
ガツトから反発して離れた後にラケットの変形が復元し
てエネルギーを放出するために、ラケットの変形により
蓄積されたエネルギーが充分にボールの反発力に寄与し
ていなかった。However, with conventional tennis rackets, when the ball rebounds from the gut when the ball is hit, the racket's deformation recovers and releases energy, so the energy accumulated by the racket's deformation sufficiently contributes to the ball's repulsive force. I hadn't.
［発明の目的］
本発明は上記事実を考慮し、ラケットの変形による蓄積
エネルギーがボールの反発力に大きく寄与することがで
きるテニスラケットを得ることが目的である。[Object of the Invention] Taking the above-mentioned facts into account, the present invention aims to provide a tennis racket in which the energy stored due to the deformation of the racket can greatly contribute to the repulsive force of the ball.
［発明の概要］

［発明の実施例］
第１図から第６図に示される如く、本実施例ではガツト
２２と、そのガツト張掛用第１開口部１４及び把手１２
を有するフレーム１０とによってテニスラケットが構成
されている。[Embodiment of the Invention] As shown in FIGS. 1 to 6, this embodiment includes a gut 22, a first opening 14 for hanging the gut, and a handle 12.
A tennis racket is constituted by the frame 10 having the following.
フレームｌＯの第１開口部１４は略楕円形である。The first opening 14 of the frame IO is approximately oval.
このフレーム１０には、第１開口部１４と把手１２との
間に略三角形の部分、即ち、いちょう部があり、そして

部２０が細幅部１８の両側に一対形成されている。従っ
ていちょう部は従来のテニスラケットのいちょう部に比
較してラケット断面積が小さくなっている。This frame 10 has a substantially triangular part, that is, a ginkgo part, between the first opening 14 and the handle 12, and a diamond-shaped second opening between the first opening 14 and the handle 12. 16 is formed, and the second opening 16 is the narrow part 1.
It communicates with the opening 14 via 8. Further, a pair of triangular third openings 20 are formed between the first opening 14 and the second opening 16 on both sides of the narrow portion 18 . Therefore, the cross-sectional area of the racket part is smaller than that of a conventional tennis racket.
フレーム１０には第１開口部１４を縦横に横切るガツト
２２が張掛けられており、このガツト２２の一部はフレ

う部へガツト２２を通す場合にも作業が容易である。Guts 22 are hung on the frame 10 and extend horizontally and vertically across the first opening 14, and a part of the guts 22 is hung up to the vicinity of the narrow part 18 of the frame 10. Since the narrow portion 18 is made very narrow, the second opening 1
6, the interval between the strings 22 can be set to any desired value. Further, since the third opening 20 is formed in the gut 22, it is easy to pass the gut 22 through the ginkgo portion.
このように構成される本実施例のテニスラケットでは、
第２開口部１６が設けられているので、第１開口部１４

し放出され、ポールのスピード増大に寄与する。In the tennis racket of this embodiment configured in this way,
Since the second opening 16 is provided, the first opening 14
and a large area spanning the entire length of the second opening 16.
The racket becomes a tennis racket similar to that when the string 2 is strung, and when hitting the ball, the bending resistance is small, and the string 22 functions similarly to a string strung on a bow. Accumulate energy. This accumulated energy is released as a repulsive force on the pole, contributing to an increase in the speed of the pole.
また、第２開口部１６はラケットの軽量化を達成すると
共に、ラケットの操作時に空気抵抗を減少する役目をも
有する。The second opening 16 also serves to reduce the weight of the racket and to reduce air resistance when operating the racket.
なお、補強材として細幅部１８へ可撓性の補強材を掛渡
しても同様な効果を有する。Note that a similar effect can be obtained even if a flexible reinforcing material is strung around the narrow portion 18 as a reinforcing material.

It has an excellent effect of accumulating and contributing to the direction of repulsion of the pole.
