Embodiment Construction

[0017] Next, the configuration of the present invention will be described in detail with reference to the drawings.

[0018] Figure 1(a) ~ Figure 1(c) Shown is a golf club head constructed from an embodiment of the present invention. Such as Figure 1(a) ~ Figure 1(c) As shown, the golf club head of this embodiment has a hollow structure formed by joining a metal shell member 11 forming the face, a sole, and a neck and a fiber-reinforced plastic shell member 21 forming a crown. Subject 1.

[0019] In the above-mentioned hollow golf club head, the position of the center of gravity can be set arbitrarily based on the combination of different types of materials, or the volume of the head can be increased as much as possible within the limited mass, thereby improving the performance including flight distance and directionality. However, the performance of golf clubs is insufficient because the metal shell member 11 and the fiber-reinforced plastic shell member 21 are simply lami...

Abstract

The present invention is hollow golf club head comprising metal outer part and fiber reinforced plastic part and with raised binding strength. The metal outer part is bound with the fiber reinforced plastic part via a binding part on two sides.

Description

technical field [0001] The present invention relates to a golf club head having a hollow structure, and more specifically, to a hollow golf club head capable of improving the bonding strength between a metal cover member and a fiber-reinforced plastic cover member. Background technique [0002] For example, Japanese Patent No. 2764883, Japanese Unexamined Patent Publication No. 2000-229135, and Japanese Patent No. 2773009 disclose golf club heads composed of composite materials of different types. According to such a golf club head, the position of the center of gravity can be arbitrarily set based on the combination of the metal material and the resin material, or the volume of the club head can be maximized within the limited mass of the club head, and the like can be improved. Golf club performance including carry distance and directionality. [0003] However, when a metal shell member and a fiber-reinforced plastic shell member are joined to form a club head body having...
