Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a racket used for tennis, badminton competitions, etc., and more particularly to a racket in which a shock transmitted to a competitor's hand as a vibration when a ball or a shuttlecock is hit is reduced.

[0002]

[Prior art]

 A racket for tennis or badminton generally has a frame, a shaft, and a grip, and is used by stretching a string on the frame. When hitting a ball or shuttlecock, the ball or shuttlecock is caught by a string stretched over the frame and rebounded by the repulsive force. Therefore, when the string collides with the ball or the shuttlecock, the athlete receives a reaction from the ball or the shuttlecock and receives an impact transmitted from the frame to the shaft and the grip.

[0003] The impact transmitted to the player's hand when hitting the ball or the shuttlecock is accompanied by vibration, and becomes a load on the player's hand and arm, which hinders accurate control of the ball or the shuttlecock. Become.

Japanese Patent Application Laid-Open No. 9-329552 discloses a structure of a golf club head that absorbs an impact transmitted to a player's hand when hitting a ball. That is, in an iron-type golf club head having a so-called cavity back structure having a concave portion on the back surface, an organic material such as butadiene rubber is attached to the concave portion.

[0005]

[Problems to be solved by the invention]

 However, a golf club and a tennis or badminton racket have completely different structures, and the above-described shock absorbing structure cannot be directly applied to the racket.

Accordingly, an object of the present invention is to provide an effective structure suitable for a racket for reducing an impact transmitted to a player's hand when hitting with the racket.

It is another object of the present invention to provide a structure for absorbing the impact so as to contribute to the improvement of aesthetic appearance.

[Means for Solving the Problems]

 In order to achieve the above object, a racket of the present invention is a racket including a frame portion, a shaft portion, and a grip portion, and at least an inner peripheral surface of the frame portion, a shaft portion, and a frame portion and a shaft portion. A concave portion is formed in at least a part selected from a yoke portion to be connected and a top cap portion provided at a boundary portion between the shaft portion and the grip portion, and a rubber-like elastic body is attached to the concave portion. I do. With this configuration, it is possible to effectively absorb the impact of hitting the ball or the shuttlecock. In addition, the rubber-like elastic body serves as an accent on the appearance, and the appearance is also improved.

In the above configuration, polyurethane is preferably used as the rubber-like elastic body.

[0010] Preferably, a concave portion provided with a rubber-like elastic body is provided on both side portions of the frame portion.

[0011] Preferably, a concave portion provided with a rubber-like elastic body is provided on both surfaces of the shaft portion parallel to the racket face surface.

Preferably, the rubber-like elastic body is made of a transparent material, and a decorative plate is further provided below the rubber-like elastic body. According to this configuration, the decorative plate further enhances the external accent due to the rubber-like elastic body, and the aesthetic appearance is further improved.

[0013] In the above configuration, preferably, a reflection pattern is provided on the surface of the decorative plate.

[0014] Preferably, the decorative plate has a plurality of holes for passing strings stretched over the frame portion, and characters are arranged between the holes.

[0015]
