Abstract

A golf club head includes a golf club head body having a connecting groove and a filling space, and a striking plate having an annular upright bent wall and a connecting end. In assembling, the connecting end of the annular upright bent wall of the striking plate is initially inserted into the connecting groove of the golf club head body so that an intensified structure is provided. The filling space of the golf club head body is further filled with a braze material. In brazing, the braze material contained in the filling space of the golf club head body is melted and thus filled within a clearance between the connecting groove of the golf club head body and the connecting end of the striking plate to form a welded layer.

Claims

1. An intensified structure for a golf club head comprising:

a golf club head body including an opening at a front side;

a braze-material filling space provided on a periphery of the opening;

a connecting groove provided on the periphery of the opening and located closely adjacent to the braze-material filling space;

a striking plate adapted to connect to the opening of the golf club head body, the striking plate further including an annular upright bent wall formed at a periphery, said annular unright bent wall being bent to align with said connecting groove which is located closely adjacent to said braze-material filling space; and

a connecting wall connected to the annular upright bent wall;

wherein said connecting wall is press-fitted into said connecting groove so that the striking plate securely connects to the golf club head body;

wherein said braze-material filling space is filled with a braze material which is melted and filled within a clearance between the connecting groove of the golf club head body and the connecting end of the striking plate to form a welded layer.

2. The intensified structure for the golf club head as defined in claim 1, wherein the golf club head body further includes an engaging shoulder engaged with an engaging shoulder of the striking plate.

3. The intensified structure for the golf club head as defined in claim 2, wherein the connecting groove includes an inner peripheral wall formed with a plurality of engaging protrusions proximate to the engaging shoulder of the golf club head body, said engaging protrusions are engaged with the connecting end of the striking plate and any two said adjacent engaging protrusions providing an auxiliary channel for receiving the melting braze material.

4. The intensified structure for the golf club head as defined in claim 1, wherein the connecting groove includes an inner peripheral wall formed with a plurality of engaging protrusions are proximate to the braze-material filling space of the golf club head body, said engaging protrusions are engaged with the connecting end of the striking plate and any two said adjacent engaging protrusions providing an auxiliary channel for receiving the melting braze material.

5. The intensified structure for the golf club head as defined in claim 1, wherein the golf club head body further includes an annular lip to form a side wall of the braze-material filling space so as to obstruct the melting braze material so that outflow of the melting braze material from the braze-material filling space can be prevented.

6. The intensified structure for the golf club head as defined in claim 1, wherein the braze-material filling space has a side wall and a bottom wall commonly defining a cornered portion.

7. The intensified structure for the golf club head as defined in claim 1, wherein the braze-material filling space has an inclination of an inclined or curved surface to the connecting groove.

8. The intensified structure for the golf club head as defined in claim 3, wherein each of the engaging protrusions has a cross-sectional shape, which is selected from a group consisting of a semi-circular section, a trapezoid section, and a triangular section, in facilitating deformation in a press fitting process.

9. The intensified structure for the golf club head as defined in claim 4, wherein each of the engaging protrusions has a cross-sectional shape, which is selected from a group consisting of a semi-circular section, a trapezoid section, and a triangular section, in facilitating deformation in a press fitting process.

10. The intensified structure for the golf club head as defined in claim 1, the braze-material flowing space has a depth at a cornered portion not greater than that of the connecting groove that permits the melting braze material flowing into the connecting groove.

11. The intensified structure for the golf club head as defined in claim 1, wherein the braze-material filling space connects with an inner peripheral wall of the connecting groove.

12. The intensified structure for the golf club head as defined in claim 1, wherein the braze-material filling space is adjacent to engaging protrusions provided on an inner peripheral wall of the connecting groove.

13. The intensified structure for the golf club head as defined in claim 1, wherein the braze-material filling space is located at an inner side of the periphery of the opening of the golf club head body.

14. The intensified structure for the golf club head as defined in claim 1, wherein the braze-material filling space is filled with the braze material prior to a braze welding process.

15. The intensified structure for the golf club head as defined in claim 1, wherein the braze-material filling space has an inclination of an inclined or curved surface to the connecting groove.

16. An intensified structure far a golf club head comprising:

a golf club head body including an opening at a front side;

a braze-material filling space provided on a periphery of the opening;

a connecting groove provided on the periphery of the opening and located closely adjacent to the braze-material filling space;

a striking plate adapted to connect to the opening of the golf club head body, the striking plate further including an annular upright bent wall formed at a periphery, said annular upright bent wall being bent to align with said connecting groove which is located closely adjacent to said braze-material filling space; and

a connecting wall connected to the annular upright bent wall;

wherein said connecting wall is inserted into said connecting groove so that the striking plate securely connects to the golf club head body;

wherein said braze-material filling space defines a height of an annular lip higher than that of an engaging shoulder of the golf club head body adjacent to the connecting groove.

17. The intensified structure for the golf club head as defined in claim 16, wherein the engaging shoulder of the golf club head body is engaged with an engaging shoulder of the striking plate.

18. The intensified structure for the golf club head as defined in claim 17, wherein the connecting groove includes an inner peripheral wall formed with a plurality of engaging protrusions proximate to the engaging shoulder of the golf club head body, said engaging protrusions are engaged with the connecting end of the striking plate and any two said adjacent engaging protrusions providing an auxiliary channel for receiving the melting braze material.

19. The intensified structure for the golf club head as defined in claim 18, wherein each of the engaging protrusions has a cross-sectional shade, which is selected from a group consisting of a semi-circular section, a trapezoid section, and a triangular section, in facilitating deformation in a press fitting process.

20. The intensified structure for the golf club head as defined in claim 16, wherein the connecting groove includes an inner peripheral wall formed with a plurality of engaging protrusions proximate to the braze-material filling space of the golf club head body, said engaging protrusions are engaged with the connecting end of the striking plate and any two said adjacent engaging protrusions providing an auxiliary channel for receiving the melting braze material.
