に違和感を与えていた。(Conventional technology) Conventionally, FRP rackets. For metal rackets, various string protectors have been disclosed for the purpose of preventing the string from breaking due to contact with the frame. First, in 1973-34138,
A synthetic resin band is fitted and attached to the outer peripheral recess of the elliptical part of the racket frame, and a number of cylindrical bodies protruding from the inner surface of the band are inserted into a number of through holes provided in the concave surface of the elliptical part of the frame. A gut protection device is disclosed in which an eyelet-like caulked gut insertion hole is formed on the inner circumferential concave surface of a frame. Also, JP-A-61-
13982 has cutting grooves that can be divided into sets one by one, and JP-A-60-36071 has sections that extend between sets of protective eyelets, and the distance between the gutt holes in the frame can be adjusted. Compatible methods are also known even if the values are different. However, in conventional gutt protectors, the gutt holes are open in the tangential direction of the frame, so when the gutt is stretched, the cylindrical part of the gutt protector and the gutt are approximately parallel to each other, so that when the ball is hit, the gutt The vibration caused the gut and the cylinder to repeatedly come into contact and separate, producing strange sounds and giving the player a sense of discomfort.

Furthermore, the tip portion 7 of the cylindrical portion 4
The hole can be enlarged if necessary.

生ずる不快な変音を防止する。(Function) As described above, in the present invention, a cylindrical portion 4 that can be inserted tightly is integrally erected in the hole 3 of the band portion 2 having a plurality of zigzag holes 3. Since the base 5 of the cylindrical portion 4 of the protector 1 is zigzag and not in a straight line, the cylindrical portion 4 of the protector 1
When the racket is fitted into the string insertion hole provided in the racket frame, the cylindrical portion 4 is inclined toward the center of the inner surface of the frame as shown in FIG. It bends at 7, generates restoring force,
The tip 7 of the cylindrical portion 4 is pushed toward the frame, and even if the gut vibrates due to the ball being hit, the gut remains in close contact with the tip 7 of the cylindrical portion 4, thereby preventing unpleasant abnormal sounds caused by the vibration of the gut. do.

When the protector 1 is molded with a mold, it is easy to remove from the mold, and furthermore, the work of attaching it to a frame is also easy, and the workability is very good. In addition,
It is preferable that the constricted portion 6 be made narrower in width or thinner than the band portion 2, or made easier to twist.

のである。(Effects) In the present invention, a cylindrical portion 4 that can be firmly inserted is integrally installed in the hole 3 of the band portion 2 having a plurality of holes 3 provided in a zigzag pattern. The base 5 of the part 4 is zigzag and is not in a straight line, so when the protector is attached to the racket frame, the gut is always in contact with the tip 7 of the cylinder part 4, which causes strange sounds. This prevents the impact, improves the sound of the ball, and also absorbs the vibration of the gut itself.
It also has a high vibration damping rate as a racket frame, reducing the strain on players' wrists and elbows.
