Abstract

A shock absorbing grip structure for a golf club capable of absorbing shock is provided.
The outside of the metal shaft end of the club is covered and fixed by adhesion. The structure is a two-layer structure of a rubber inner layer 30 and an outer layer 31. The inner layer of the rubber has an appropriate thickness, there are a few ring-shaped grooves 310 formed on the surface, and an adhesive layer on the back surface. Adhesive fixed to the end. The outer surface of the rubber is directly covered with the adhesive layer 300 on the outer layer of the grip, and the ring-shaped groove of the inner layer of the rubber is sealed to the back surface of the outer layer by docking with the outer layer to create a ring-shaped space. The ring-shaped space is located in the center of the grip structure, and the effect of isolating the ring-shaped space capable of absorbing the impact is to reduce the volume for conducting the force, so that the impact force transmitted to the hand is reduced to the minimum.

Description

  The present invention relates to a grip structure of a golf club that can provide an impact absorbing function.

  Most conventional golf club grips have rubber coating 1 as the main component, and most of them are adhesively fixed directly to the end of the metal shaft, but the impact force of the swing is transmitted to the player's hand via the rubber coating. In order to eliminate the problem, it is usually considered a method to improve by adjusting the hardness of the material of the rubber coating. However, in order to eliminate the impact, the effect is limited even if soft rubber is used. In addition, the grip feeling of the palm of the player tends to be lowered, and it resonates with the swing. Therefore, there seems to be room for improvement in the preceding grip. Another type of rubber coating structure (see FIG. 2) has some ring-shaped grooves 20 on the back surface of the rubber coating 2. Since an adhesive is applied to the back surface of the rubber coating 2 and the rubber coating 2 is directly adhered and fixed to the end of the metal shaft 21, the opening direction of each ring-shaped groove 20 is bonded to the metal shaft 21 to form an isolation space. As a result, the impact force transmitted from the shaft passes through the isolation space, and the impact force transmitted to the hand is reduced. However, since the adhesive area between the rubber coating 2 and the end of the metal shaft 21 is reduced due to the arrangement of the ring-shaped groove 20, the rubber coating 2 is easily loosened, which may hinder the swing. Therefore, there seems to be room for improvement as with the preceding grip.

  The main object of the present invention is to provide a grip structure capable of absorbing shock, thereby lowering the impact force received by the player's hand and enhancing the grip feeling of the palm.

  The present invention is an impact-absorbing grip structure that covers the end of a golf club metal shaft, and has a two-layer structure of an inner layer and an outer layer of rubber. The inner layer of the rubber is a rubber layer having an appropriate thickness, and has some ring-shaped grooves on the surface. The back surface of the rubber inner layer covers the end of the metal shaft and is adhesively fixed. The outer layer is also a rubber layer having an appropriate thickness, covers the surface of the rubber inner layer, and is adhesively fixed. The structure in which the rubber inner layer and the outer layer are docked is the main structure. Since the ring-shaped groove on the surface of the rubber inner layer located in the center of the grip structure creates a ring-shaped isolation space, the impact force generated during the swing is first partially absorbed and weakened by the inner layer. Next, since the isolation effect of the ring-shaped space reduces the volume for conducting force, the impact force once weakened is weakened again. As a result, only a slight impact force can be felt at hand, and a stable swing effect can be realized.

  As shown in FIG. 3, the grip structure of this embodiment is composed of a rubber inner layer 30 and an outer layer 31, covering the metal shaft end 3 and being adhesively fixed. The rubber inner layer 30 is a rubber layer having an appropriate thickness, and has a ring-shaped groove 310 on the surface. The back surface on which the adhesive layer 300 is evenly applied is directly covered with the metal shaft end 3 and is adhesively fixed to the metal shaft 3. The thickness of the outer layer 31 of the grip is best from 1.5 mm to 2.0 mm. The back surface on which the adhesive is evenly applied covers the surface of the rubber inner layer 30 and is bonded to the opening of the ring-shaped groove 310 (see FIG. 4). By the docking of the rubber inner layer 30 and the outer layer 31, the opening of the ring-shaped groove 310 is sealed to the back surface of the outer layer 31 to create a ring-shaped space. Moreover, this ring-shaped space is located at the center of the grip structure. The cover 4 is put on the structure in which the rubber inner layer 30 and the outer layer 31 are combined. When the fixing pole protruding from the cover 4 is fixed to the hollow structure of the metal shaft, the grip is fixed to the end of the metal shaft.

  Reference is made to FIGS. When the ball is hit with the club using this embodiment, the generated impact force is transmitted to the grip of the end 3 through the metal shaft, and is first partially absorbed by the rubber inner layer 30 and weakened to some extent. Next, the ring-shaped space formed by the ring-shaped groove 310 of the outer layer 31 reduces the volume for conducting the force, so that the impact force is again weakened to a level that can be said to be minimal. Finally, it is completely absorbed by the surface structure of the outer layer 31, and finally only a very small impact force is transmitted to the player's hand, so that a stable swing effect is required (see FIG. 7).

  8 and 9 show another embodiment of the present invention. This grip structure is also composed of a rubber inner layer 5 and an outer layer 6. The rubber inner layer 5 is a rubber layer having an appropriate thickness, and has some longitudinal grooves 50 on the surface, and an adhesive layer 500 is applied on the back surface. It directly covers the metal shaft end 3 and is fixed by adhesion.
