この考案は、例えばテニスラケツトなどにおけ
るフレーム張弦部の重量調整に改良を施したラツ
トフレームに関するものである。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a rat frame in which the weight adjustment of the stringing part of the frame is improved in, for example, a tennis racket.
［従来の技術］
一般に、市販されているテニスラケツト等のラ
ケツトフレームは、使用者の技量に応じて初級・
中級・上級用といつた３段階に大別にされてそれ
ぞれに適宜の重量調整を施している。[Prior Art] Generally, commercially available racket frames such as tennis rackets are designed for beginners and players depending on the skill of the user.
It is roughly divided into three levels, intermediate and advanced, and the weight is adjusted appropriately for each.

バランスを設定するなどして、重量の調整が行な
われているのが現状である。 When adjusting the weight of such a racket frame, a weight adjusting member is usually embedded in the stringing part or grip part of the frame during the manufacturing stage, or is fixed by pasting.
Alternatively, the weight is currently adjusted by setting the weight balance of the entire frame at the frame design stage.

た、このような剥がれによつて外観性が悪くな
る。 For this reason, the weight adjustment means of the racket frame in the conventional structure described above not only makes it impossible for the user to further fine-tune the racket frame according to his or her own skill after purchase, but also makes it particularly difficult to adjust the weight of the racket frame. For items that are pasted on a frame,
There is a risk that it will peel off and fall off during play, and such peeling will worsen the appearance.
そこで、上記のような不具合を解消する手段と
して、本出願人が昭和59年６月29日付で出願した

る構成を有するものが提案されている。 Therefore, as a means to solve the above-mentioned problems, as disclosed in Japanese Patent Application No. 59-134514 and Japanese Patent Publication No. 1-50427 filed by the present applicant on June 29, 1980, the frame stringing section A weight adjustment member made of a band-shaped base material is partially attached to the outer peripheral surface of the
In addition, a structure has been proposed in which the weight adjustment member can be held by a string that is folded back and stretched on the frame stringing section.

ツト張りして保持されるようになつている。 The weight adjustment member used to adjust the weight of the racket frame in this type of prior invention is a belt-shaped base material that can be separated in predetermined weight units, and a cylindrical gut protection member that is inserted into a gut insertion hole. At the time of tightening at a store after purchase, it is cut to an appropriate length and weight according to the user's preference and partially attached to a predetermined position on the outer peripheral surface of the frame stringing part. At the same time, after each gut protection member is inserted into the corresponding gut insertion hole, it is tightened and held.

合がある。 However, in the manufacturing process, a string protection member is installed in advance over the entire circumferential length of the frame, either alone or together with a protective band, in the numerous string insertion holes formed through the frame stringing part of commercially available racket frames. There are racket frames that are attached continuously, and when the above-mentioned racket frame weight adjustment means of the prior invention is applied to such a racket frame, the weight of the part corresponding to the attached part of the weight adjustment member is reduced. Not only is it necessary to remove the protective member, making it impossible to use them together, but there are also disadvantages such as the fact that once the protective member has been tightened, the weight cannot be adjusted by attaching a weight adjusting member.

提案されている。 Furthermore, as a means to eliminate such problems, as disclosed in Utility Model Application No. 88390/1988 filed by the present applicant on June 10, 1988, and Patent Application No. 200357/1983 filed by the present applicant, Gutto protection is proposed. A structure has been proposed in which a weight adjusting member is removably fitted into a concave and convex portion of the member, thereby making it possible to adjust the weight by attaching the weight adjusting member after tightening.

たな問題が生じる。[Problems to be solved by the invention] However, in the structure of attaching the weight adjustment member in the above-described invention of the prior application, in order to make the weight adjustment member movable as necessary, the gut protection member and the weight Since the width of the concave and convex fitting part with the adjustment member is made equal along the frame circumferential direction to enable sliding, the frame circumference of the weight adjustment member is adjusted by the impact at the time of hitting the ball and the centrifugal force caused by the swing. In order to prevent such slight movement of the weight adjustment member, the concave and convex fitting portions of the gut protection member and the weight adjustment member are made with high precision. Although it is conceivable that the weight adjustment member may be moved as required, this would cause a new problem such as the inability to move the weight adjustment member as necessary.

Gut G is designed to be inserted by turning it.
Further, on the outer peripheral side surface 5a of the gut protection member 5, a male fitting portion 53 having a cross-sectional shape in the shape of a male slide rail is formed so as to protrude continuously or partially integrally along the entire circumferential length of the frame. A weight adjustment member 6 having an arbitrary length depending on the degree of weight adjustment is fitted and held in the male fitting portion 53.

It has a recessed groove-shaped female fitting part 62 having a cross-sectional shape like a mold slide rail,
By fitting this female fitting part 62 into the female fitting part 53 of the gut protection member 5, the female fitting part 62 is slidably attached to the outer peripheral surface 2a of the frame stringing part 2 along the frame circumferential direction. The surface portion thereof is formed into an arcuate curved surface to reduce air resistance, and preferably has a width dimension of the outer circumferential surface 2a of the frame stringing portion 2. are strip-shaped base materials 61 with approximately equal width dimensions.
By forming this, it is possible to cover almost the entire width of the outer circumferential surface 2a of the frame stringing section 2, including the gut protection groove 4, and thereby,
This makes it possible to improve the appearance.

うになつているものである。 Further, FIGS. 7 and 8 show other embodiments of this invention, in which the female fitting portion 62 of the weight adjustment member 6
A pair of convex portions 63, 63 are formed by narrowing the width W 2 at one place.
On the other hand, the width W 1 of the male fitting portion 53 of the gut protection member 5 is narrowed at a plurality of locations to form a pair of recesses 54, 54, etc., and these uneven portions are selectively engaged with each other. This prevents slight movement in the circumferential direction of the frame due to impact when hitting a ball and centrifugal force when swinging, while also making it possible to adjust the movement in the circumferential direction of the frame as necessary. By partially narrowing the mutual uneven fitting widths W 1 and W 2 of the male fitting part 53 of the gut protection member 5 and the female fitting part 62 of the weight adjusting member 6, the weight adjusting member 6 can be prevented from sliding at a predetermined position on the outer circumferential surface 2a of the frame stringing part 2 of the racket frame body, thereby preventing slight movement in the frame circumferential direction due to impact when hitting a ball and centrifugal force when swinging. In addition, the frame can be moved and adjusted in the circumferential direction of the frame as necessary.
