剛性を得るようにしたものである。[Detailed description of the invention] This invention relates to improving the grip structure of wooden rackets used for tennis, etc., by changing the strength of the grip shape-retaining side plates attached to the shaft of the racket frame. The shaft is designed to have rigidity that corresponds to the batting force used when hitting by hand or with both hands.

ヤも増えている。 In general, most players use a one-handed batting method, using a forehand for the ball on the dominant side and a back band for the ball on the opposite side. On the other hand, the number of players who hit with both hands is also increasing.

どの不具合があつた。 However, in the conventional racket of this kind, as illustrated in FIGS. 1 to 3, when a grip is formed on the end side of the shaft portion 2 of the racket frame 1, each grip on the shaft portion 2 having a rectangular cross section is After attaching the side plates 3, 3, 4, and 4 for grip shape retention to the surface and retaining the shape of the grip, for example, an octagonal cross section and an appropriate thickness, a hand skin (not shown) is attached to the peripheral surface of the grip. )
However, in such a conventional structure, the shape-retaining side plates 3, 3, 4, 4 attached to each side of the shaft portion 2 so as to face each other have a length and a thickness. Since both have the same dimensions, the shaft bending rigidity in the direction of hitting the ball is the same. Therefore, when you hit the front with one hand or the back with both hands, there is a difference in the hitting power between the two.
There were problems such as the feeling of hitting the ball was different between the front and back.
この考案は、上記従来の欠点を解消することを
目的としたもので、第４図以下に示す実施例に基
づいて説明する。尚、この考案に係る図示の実施
例において、上記した従来構造と構成が重複する
部分は同一符号を用い説明を省略する。 This invention is aimed at solving the above-mentioned conventional drawbacks, and will be explained based on the embodiments shown in FIG. 4 and subsequent figures. Incidentally, in the illustrated embodiment of the present invention, parts having the same structure as the conventional structure described above are designated by the same reference numerals, and a description thereof will be omitted.
すなわち、この考案は、第４図及び第５図に示
すように、ラケツトフレーム１のシヤフト部２に
添設されるグリツプ保型用側板、特に表裏打球面
側に互いに対面させて添設される表面側の保型用
側板４１の長さ１と、裏面側の保型用側板４２
の長さ２を１＜２の関係で異ならせてなる
構成を有するものである。 That is, as shown in FIGS. 4 and 5, this invention is based on the grip shape retaining side plates attached to the shaft portion 2 of the racket frame 1, in particular attached to the front and back ball hitting surfaces facing each other. The length 1 of the side plate 41 for shape retention on the front side and the side plate 42 for shape retention on the back side.
It has a structure in which the lengths 2 of the two are different in the relationship 1 < 2 .
ところで、上記実施例における保型用側板４
１，４２の長さ１、２は、例えば１＝47
mm、２＝80mmであるが、好ましくは30mm＜１
＜60mm，65mm＜２＜100mmの範囲でプレーヤの
技量に応じ適宜調整される。 By the way, the shape-retaining side plate 4 in the above embodiment
The length 1 , 2 of 1,42 is, for example, 1 = 47
mm, 2 = 80 mm, but preferably 30 mm < 1
Adjust as appropriate depending on the skill of the player within the range of <60mm, 65mm< 2 and <100mm.
したがつて、上記したこの考案に係る構成によ
れば、表裏打球面側に添設されるグリツプ保型用
側板の長さを異ならせたことから、打球時のシヤ
フト曲げ剛性が表裏側方向（フオア）と裏面側
（バツク）方向とで異なり、シヤフト曲げ剛性が
大きい方を両手打ちによるバツクハンド打法で打
撃すれば、打力とシヤフトの剛性との相乗効果に
よつて打球速度が増大し、かつ片手打ちのフオア
ハンドによる打撃と同様の打球感を得ることがで
きるなど、実用性にすぐれた効果を奏するもので
ある。 Therefore, according to the above-mentioned configuration according to this invention, since the lengths of the grip shape retaining side plates attached to the front and back ball-hitting surfaces are made different, the shaft bending rigidity when hitting a ball is increased in the front-back direction ( If the shaft bending rigidity is different in the front direction and back direction, and if you hit with a two-handed backhand batting method, the batted ball speed will increase due to the synergistic effect of the batting force and the rigidity of the shaft. Moreover, it has excellent practical effects, such as being able to obtain the same feel at impact as with a one-handed forehand hit.
