Description

[Detailed Description of the Invention] This invention relates to a frame protector for protecting the frame of a racket for tennis, badminton, etc.

Generally, this type of racket uses wooden plywood, fiber reinforced plastic (FPR), or the like as the frame material, and various improvements have been made to reduce the weight. One way to do this is to narrow the width or reduce the thickness of the frame, but on the other hand, narrowing the width or reducing the thickness has the disadvantage that the frame is more likely to be damaged. Particularly in all-weather tennis courts, the court surface is hard, so when the frame of the racket comes into contact with the court surface, the frame is easily scratched and damaged.

Conventionally, in order to eliminate this drawback, synthetic resin strings have been wrapped around the frame to protect the frame. However, with this kind of string, if the court surface comes into contact with a hard surface such as an all-weather tennis court, it will break immediately and lack durability, and furthermore, it must be wrapped tightly around the frame, so it is very difficult to wrap it around the frame. It had drawbacks such as being troublesome.

This idea was made in view of the above circumstances, and its purpose is to protect the frame without sacrificing weight reduction, and to be durable even when used on hard court surfaces. To provide a racket frame protector which is excellent in performance and is extremely easy to attach to the frame.

That is, this invention has a tube shape with a polygonal or circular cross section, which has a slit formed in the length direction, and has a large diameter part and a small diameter part, and the small diameter part tightly fits and grips the frame. This is a racket frame protector characterized by being made of a flexible material.

This invention will be explained below based on an embodiment shown in the drawings. In Figs. 1 to 3, 1 is a protector, and a larger diameter portion 2 is made of a flexible material such as synthetic rubber or vinyl chloride resin. It is formed into a tube-like shape with a rectangular cross section and a small diameter portion 3, and a slit 4 is provided in the length direction thereof.

The width of the slit 4 is smaller than the frame width of the racket, and is wide enough to accommodate the frame 5 when opened. Further, the inner diameter of the small diameter portion 3 of the protector is set to be approximately the same as the thickness and width of the frame, and the small diameter portion 3 tightly grips the frame 5. Note that if the small diameter portion 3 is insufficient to grip the frame, the protector and the frame 5 may be fixed together using double-sided tape.

Further, the inner diameter of the large diameter portion 2 is set to have a space between it and the frame 5, so that when the large diameter portion 2 comes into contact with the court surface, the frame is protected and buffered by the space. ing.

However, in order to attach the protector of this invention to the frame 5 of the racket, it is extremely easy to attach it by opening the 4 slits of the protector and allowing the protector to fit over the frame 5 from there.

In this embodiment, the shape of the protector is described as being tube-like with a quadrangular cross-section, but the cross-sectional shape is not limited to this, and may be, for example, circular, elliptical, hexagonal, or the like. Also, regarding the length, it is not necessary to attach it to the entire frame, but it is sufficient to use one of an appropriate length and attach it partially to the part of the frame that easily comes into contact with the court.

According to this invention with the above-mentioned structure, it can be attached to the frame of the racket extremely easily, and since there is a space in a part of the protector, it is possible to prevent contact with the court surface due to the material of the protector. It can buffer the impact.

Further, the protector can be integrally molded by ordinary resin molding, and has many advantages such as being inexpensive to manufacture and having excellent durability.
