Abstract

A golf club head includes a hollow head body, a metal plate, and a compression resistant plate. The hollow head body is formed with an opening. The metal plate is fixed to the hollow head body, covers the opening, and has a thickness ranging from 0.1 to 0.5 mm. The compression resistant plate is bonded to an inner surface of the metal plate and spans the opening.

Claims

1. A golf club head, comprising:

a hollow head body formed with an opening;

a metal plate fixed to said hollow head body, covering said opening, and having a thickness ranging from 0.1 to 0.5 mm; and

a compression resistant plate bonded to an inner surface of said metal plate and spanning said opening.

2. The golf club head as claimed in claim 1, wherein said hollow head body includes an inner periphery that defines said opening, and that is stepped to form a shoulder formation around said opening, said metal plate being seated on and fixed to said shoulder formation.

3. The golf club head as claimed in claim 2, wherein said compression resistant plate is fitted in said opening.

4. The golf club head as claimed in claim 3, wherein said head body further includes two opposite anchoring holes, said compression resistant plate including a rib projecting inwardly from said compression resistant plate, spanning said opening, and engaging said anchoring holes.

5. The golf club head as claimed in claim 1, wherein said compression resistant plate has a specific gravity less than 2.8.

6. The golf club head as claimed in claim 1, wherein said compression resistant plate is made of a material selected from the group consisting of a carbon fiber composite material, a glass fiber composite material, a boron fiber composite material, a short fiber thermoplastic composite material, a titanium fiber composite material, a titanium mesh composite material, an aluminum alloy, and a magnesium alloy.

7. The golf club head as claimed in claim 1, wherein said metal plate is made of a material selected from the group consisting of a titanium alloy, an aluminum alloy, a magnesium alloy, and a stainless steel.

8. The golf club head as claimed in claim 1, wherein said metal plate is glued to said hollow head body.

9. The golf club head as claimed in claim 1, wherein said metal plate is brazed to said hollow head body.

10. The golf club head as claimed in claim 1, wherein said metal plate is resistance-welded to said hollow head body.

11. A golf club head comprising:

a metallic hollow head body having a front striking face, a rear side opposite to said front striking face, a top side, and an opening formed at said top side;

a metal plate formed as a separate piece from said hollow head body, said metal plate being fixed to said hollow head body and covering said opening; and

a compression resistant plate glued to an inner surface of said metal plate and spanning said opening, said compression resistant plate having a specific gravity less than that of said hollow head body,

whereby the center of gravity of the golf club head is lowered.

12. The golf club head as claimed in claim 11, wherein said metal plate has a thickness smaller than that of a wall of said hollow head body.

13. The golf club head as claimed in claim 11, wherein the specific gravity of said compression resistant plate is less than 2.8.

14. The golf club head as claimed in claim 11, wherein said compression resistant plate has a rib projecting inwardly from said compression resistant plate, spanning said opening, and extending in a front-to-rear direction.
