本発明は、テニスラケットやバドミントンラケット用の
ガツトに関する。DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a gut for a tennis racket or a badminton racket.
〈従来技術〉
従来、ガツトには弾力性に富むナイロン糸が多用されて
いる。そして、ラケットで打球する際には、どのストロ
ークでもなんらかの形でボールに回転を与えている。<Prior Art> Conventionally, highly elastic nylon threads have been frequently used for guts. When hitting a ball with a racket, every stroke imparts some form of rotation to the ball.
例えば、サーブのときの回転は、ツイスト、スピン、カ
ット、カーブ等、グランドストロークのときの回転は、
トップスピン、ドライブ、スライス等である。For example, the rotation during a serve is twist, spin, cut, curve, etc., and the rotation during a ground stroke is
Topspin, drive, slice, etc.
そして、ボールの回転は、フン）ロールをつけるのに絶
対必要で、相手のエラーを誘い出したり、相手の好まぬ
ショットを送るのに有効である。The rotation of the ball is absolutely necessary to create a roll, and is effective in inducing errors from the opponent or sending shots that the opponent does not like.

点がある。In other words, the easier the gut is to impart rotation to the ball, the better. Therefore, as shown in Figure 10, the conventional hard type
There is also a structure in which many nylon threads 10, 11 are twisted together and a stainless steel wire 12 is threaded through the center, but this has the disadvantage of being expensive. Furthermore, as shown in FIG. 11, most strings for hardball and strings for softball are threads with a circular cross-section, which has the disadvantage of making it difficult to impart rotation to the ball.
〈目的〉
そこで、本発明は安価でボール（シャトルコックを含む

している。<Purpose> Therefore, the present invention aims to provide a racket gut that is inexpensive and allows a ball (including a shuttlecock) to easily rotate.
〈実施例〉
以下、第１図ないし第９図の第一実施例ないし第九実施
例について本発明を説明する。<Example> The present invention will be described below with reference to the first to ninth embodiments shown in FIGS. 1 to 9.

る。First, the first embodiment will be explained based on FIG. 1. The guts A1 stretched on the frame F are 2, a small-diameter core 1 and three or more protrusions 2 formed protruding from the outer circumference at equal pitches. A protrusion 4 made of synthetic resin and having a constant cross-sectional shape composed of
It consists of attached threads. And this Gatsuto A1 is
It is suitable that the outermost diameter of the die is around 2 pairs, and the die is made of engineering plastic such as nylon or Tetron and has a cross-sectional shape (star shape), and the same molten material as before is poured into hot air or solidified liquid. Manufactured by extrusion.

Ｂと同じと仮定すれば、突子２の先端は当然従来の直径
りよる突出するの゛ で、断面二次モーメントは大きく
なり、曲げ強度は増し、大きな弾性変形が可能となるの
で、弾性が増す。The diameter d of the small-diameter core 1 and the thickness t of the protrusion 2 of the above-mentioned guttat) At are significantly smaller than the diameter D of the conventional gut B (when both have the same cross-sectional area). Therefore, the material for both is the same, and the cross section is
Assuming that it is the same as B, the tip of protrusion 2 will naturally protrude more than the conventional diameter, so the moment of inertia of area will increase, the bending strength will increase, and large elastic deformation will be possible, so the elasticity will increase. Increase.

である。Further, the cross-sectional shape of (A2) in the second embodiment in FIG. 2, A3 in the third embodiment in FIG. 3, and LA4 in the fourth embodiment in FIG. 4 are cross-shaped. Further, the cross-sectional shape of the gut A5 of the fifth embodiment shown in FIG. 5 is a figure 7 shape. The structure of the pond in these embodiments is the same as that in the embodiment described above.
It is.

である。“Furthermore, A6 of the sixth embodiment in FIG.
The cross-sectional shape is a star shape with three center holes, and the cut A7 of the seventh embodiment in FIG. 7 has a cross-sectional shape with three center holes.
The cross section of the eighth embodiment A8 in FIG. 8 is a sprocket shape with three center holes, and the cross section A9 of the ninth embodiment in FIG. 9 is a Y-shaped cross section with three center holes. A wire rod 5 made of stainless steel or the like is inserted into the center hole 3 as necessary to increase elasticity and strength. Note that the other configurations of these embodiments are the same as those of the first embodiment.
