Abstract

A golf club head includes a golf club head body and a weight member mounted in a recession of the golf club head body. The weight member includes at least one compartment for receiving a filling material. The weight member is mounted in the recession of the golf club head body before a brazing process for bonding the weight member with the golf club head body. During the brazing process, the filling material is melted and fills a gap between the weight member and walls delimiting the recession of the golf club head body to thereby increasing bonding strength between the weight member and the walls delimiting the recession of the golf club head body.

Claims

1. A weight member for a golf club head, the weight member being adapted to be mounted in a recession of a golf club head body of a golf club head, the weight member comprising at least one compartment for receiving a filling material, the weight member being mounted in the recession of the golf club head body before a brazing process for bonding the weight member with the golf club head body, the filling material being melted and filling a gap between the weight member and a plurality of walls delimiting the recession of the golf club head body during the brazing process to thereby increasing bonding strength between the weight member and the walls delimiting the recession of the golf club head body.

2. The weight member as claimed in claim 1, wherein the weight member includes a plurality of engaging sides for bonding with the walls delimiting the recession of the golf club head body, each said engaging side of the weight member including at least one channel for receiving and guiding molten filling material during the brazing process.

3. The weight member as claimed in claim 1, wherein said at least one channel has a depth between 0.03 mm and 0.2 mm.

4. The weight member as claimed in claim 2, wherein the weight member includes a top engaging face in which said at least one compartment is defined, said at least one channel extending to the top engaging face of the weight member and communicating with said at least one compartment.

5. The weight member as claimed in claim 2, further including at least one extension channel defined in at least one of the engaging sides of the weight member, said at least one extension channel communicating with said at least one channel of said at least one of the engaging sides of the weight member and extending in a direction transverse to said at least one channel of said at least one of the engaging sides of the weight member.

6. The weight member as claimed in claim 2, wherein the weight member further includes at least one connecting hole defined therein for communicating said at least one compartment and said at least one channel.

7. The golf club head as claimed in claim 1, wherein said at least one compartment includes at least one opening.

8. A golf club head comprising:

a golf club head body including a recession; and

a weight member mounted in the recession of the golf club head body, the weight member comprising at least one compartment for receiving a filling material, the weight member being mounted in the recession of the golf club head body before a brazing process for bonding the weight member with the golf club head body, the filling material being melted and filling a gap between the weight member and a plurality of walls delimiting the recession of the golf club head body during the brazing process to thereby increasing bonding strength between the weight member and the walls delimiting the recession of the golf club head body.

9. The golf club head as claimed in claim 8, wherein the recession of the golf club head body being delimited by a bottom wall and a plurality of side walls, the bottom wall including a plurality of positioning holes, the weight member including a plurality of positioning pegs respectively received in the positioning holes in a manner that the bottom wall delimiting the recession of the golf club head body is spaced from the weight member.

10. The golf club head as claimed in claim 8, wherein the filling material is solid.

11. The golf club head as claimed in claim 10, wherein an overall volume of said at least one compartment of the weight member is not less than that of the gap between the weight member and the walls delimiting the recession of the golf club head body.

12. The golf club head as claimed in claim 8, wherein the filling material is a pasty filling material containing a bonding agent.

13. The golf club head as claimed in claim 12, wherein an overall volume of said at least one compartment of the weight member is two times of that of the gap between the weight member and the walls delimiting the recession of the golf club head body.

14. The golf club head as claimed in claim 8, wherein said at least one compartment includes at least one opening.

15. The golf club head as claimed in claim 8, wherein the weight member includes a plurality of engaging sides, the walls delimiting the recession of the golf club head body including a plurality of side walls for bonding with the engaging sides of the weight member, each said engaging side of the weight member including at least one channel for receiving and guiding molten filling material during the brazing process.

16. The golf club head as claimed in claim 8, wherein said at least one channel has a depth between 0.03 mm and 0.2 mm.

17. The golf club head as claimed in claim 16, wherein the weight member includes a top engaging face in which said at least one compartment is defined, said at least one channel extending to the top engaging face of the weight member and communicating with said at least one compartment.

18. The golf club head as claimed in claim 15, further including at least one extension channel defined in at least one of the engaging sides of the weight member, said at least one extension channel communicating with said at least one channel of said at least one of the engaging sides of the weight member and extending in a direction transverse to said at least one channel of said at least one of the engaging sides of the weight member.

19. The golf club head as claimed in claim 15, wherein the weight member further includes at least one connecting hole defined therein for communicating said at least one compartment and said at least one channel.

20. The golf club head as claimed in claim 15, wherein said at least one channel is defined on each of two opposed side walls delimiting the recession of the golf club head body, the weight member further including at least one connecting hole defined therein, said at least one connecting hole having a first end communicated with said at least one channel on one of the opposed side walls delimiting the recession of the golf club head body and a second end communicated with said at least one channel on another of the opposed side walls delimiting the recession of the golf club head body.
