Abstract

A golf club which comprises a head which is less deformable by the heat in welding. Separate reinforcing members 12 and 13 are provided on inner surface of a front edge 8A of a crown shell 8. Thus, the front edge 8A side is thickened and then the upper edge 4A of the face shell 4 is joined to the front edge 8A of the crown shell 8, by welding. The front edge 8A of the crown shell 8 is formed with a plurality of projections 11 which are anchored by the upper edge 4A of the face shell 4. front edge 8A of the crown shell 8 is thickened by adding the thickness of the reinforcing members 12, 13 to the thickness of crown shell 8 itself. Thus, thermal deformation and the sinking of the front edge 8A at the time of welding can be prevented, thus enabling the upper edge 4A to be joined to the front edge 8A as designed.

Claims

1. A golf club comprising:

a head formed by joining a plurality of separate shells one another, said separate shells including a first separate shell and a second separate shell;

a shaft connected to said head; and

a reinforcing means provided for reinforcing joint strength between said first separate shell and second separate shell, said reinforcing means being provided in a peripheral portion of at least said first separate shell.

2. A golf club according to claim 1, wherein said peripheral portion of said first separate shell is thickened partially or entirely.

3. A golf club according to claim 1, wherein said reinforcing means is a separate reinforcing member which is partially or entirely provided on an inner surface of said peripheral portion of said first separate shell, so that it is thickened.

4. A golf club according to claim 3, wherein said seperate reinforcing member protrudes from an end of said first separate shell.

5. A golf club according to claim 1, wherein a plurality of projections are provided on an end of at least said first separate shell so that said projections are anchored by an end of said second separate shell.

6. A golf club according to claim 1, wherein cladding is partially or entirely provided on an inner surface of said first separate shell.

7. A golf club according to claim 1, wherein said head is of a wood type.

8. A golf club according to claim 5, wherein said projections protrude by a length which is less than or at most equal to a thickness of said second separate shell.

9. A golf club according to claim 7, wherein a clearance is formed between an upper edge of a face shell and a front edge of a crown shell, while a weld bead is provided in the clearance.
