Golf club head

Golf club head description/claims

1. Field of the Invention

The present invention relates to a golf club head, and more especially, to the golf club head with a composite plate.

2. Background of the Related Art

In general, the golf club head 10, as shown in FIG. 1, includes a head body 12 and a striking plate 14. An opening 121 is formed on the front part of the head body 12 and a tab 122 around the opening 121. The striking plate 14 has an outer surface 142 and an inner surface 141 with a welding area (not shown) corresponding to the tab 122 on the rim of the inner surface 141. The tab 122 and the welding area are welded together so as to combine the striking plate 14 and the head body 12.

However, according to the foregoing design of arranging the welding area on the rim of the inner surface, the striking area of the striking plate will be reduced because of the limitation of the welding area to affect the striking function. On the other hand, if the striking plate is a composite plate which is made by the explosion welding, the combination intensity of the composite plate will be destroyed due to the high welding temperature from the welding area to affect the quality of the golf club head.

In order to solve the foregoing problems, one object of this invention is to provide a golf club head which is formed by welding a cup face and a head body, wherein the cup face is manufactured by combining at least two different substrates in the explosion welding way, and the explosion welding areas of different substrates are far away from the welded areas between the cup face and the head body because of the design of the bending portion of the cup face, so that the high welding temperature will not cause the separation of different substrates and effectively enhance the quality of the golf club head.

One object of this invention is to provide a golf club head, wherein because the welded areas between the cup face and the head body are far away from the striking area, the striking area can be expanded to enhance the striking function which was limited by the welded areas in the past.

One object of this invention is to provide a golf club head with better striking feeling.

One object of this invention is to provide a golf club head having better elasticity to increase the striking distance, and the mass center of the golf club head can be adjusted by using different substrates to satisfy the weight distribution that the weight of outside portion of the golf club head is lighter than the weight of inside portion of the golf club head.

Accordingly, one embodiment of the present invention provides a golf club head including: a head body having an opening on a front part of the head body, and a connection portion around the opening; and a cup face including: a main board having a bending portion toward the head body on at least one edge of the main board, wherein a joint surface is formed on an edge of the bending portion to be combined with the connection portion of the head body; and a board structure stacked with the main board, wherein the material of the board structure is different from the material of the main board.
