Abstract

A golf club head includes a body and at least one light cover. The body includes a striking face for striking golf balls and a crown. At least one recessed portion is defined in the crown and includes a bonding face. The bonding face includes a plurality of regularly arranged holes spaced by a plurality of resilient ribs. The light cover is securely mounted to the recessed portion. The light cover and the holes reduce a weight of the crown of the golf club head and improve a rearward resilient deforming capacity of the striking face. Further, the resilient ribs assure strength of the recessed portion.

Claims

1. A golf club head comprising:

a body including a striking face for striking golf balls, the body including a crown, at least one recessed portion being defined in the crown and including a bonding face integrally formed in the recessed portion of the body, the bonding face including a plurality of regularly arranged holes spaced by a plurality of resilient ribs, said recessed portion running across the crown, said recessed portion further extending from the crown toward at least one of a toe and a heel, and bending to form at least one of a toe-side sidewall portion and a heel-side sidewall portion; and

at least one light cover securely mounted to said at least one recessed portion, said light cover extending from a crown portion toward at least one of a toe and a heel, and bending to form at least one of a toe-side sidewall portion or a heel-side sidewall portion, said at least one light cover and said holes reducing a weight of the crown of the golf club head and improving a rearward resilient deforming capacity of the striking face, and the resilient ribs assuring strength of the recessed portion.

2. The golf club head as claimed in claim 1, with each side hole of the recessed portion being one of circular and polygonal.

3. The golf club bead as claimed in claim 2, with each said hole of the recessed portion being one of hexagonal, square, and triangular.

4. The golf club head as claimed in claim 1, with each said hole of the recessed portion being one of elongated, conic, and corrugated.

5. The golf club head as claimed in claim 1, with said holes of the recessed portion having different sizes.

6. The golf club head as claimed in claim 1, with each said hole of the recessed portion extending from a front side of a body toward a rear side of the body.

7. The golf club head as claimed in claim 1, with the light cover being made of a light material selected from the group comprising carbon fiber, rubber, plastics, magnesium alloy, and aluminum alloy.

8. The golf club head as claimed in claim 1, with the light cover being bonded by elastomeric filler to the bonding face of the recessed portion, with the elastomeric filler made of a material selected from the group comprising thermoplastic elastomeric material, rubber, high molecular polymeric material, and polyurethane.

9. The golf club head as claimed in claim 1, with the resilient ribs being connected with one another.

10. The golf club head as claimed in claim 9, with each said hole of the recessed portion being one of circular and polygonal.

11. The golf club head as claimed in claim 10, with each said hole of the recessed portion being one of hexagonal, square, and triangular.

12. The golf club head as claimed in claim 9, with each said hole of the recessed portion being one of elongated, conic, and corrugated.

13. The golf club head as claimed in claim 9, with said holes of the recessed portion having different sizes.

14. The golf club head as claimed in claim 9, with each said hole of the recessed portion extending from a front side of the body toward a rear size of the body.

15. The golf club head as claimed in claim 9, with the light cover being made of a light material selected from the group comprising carbon fiber, rubber, plastics, magnesium alloy, and aluminum alloy.

16. The golf club head as claimed in claim 9, with the light covet being bonded by elastomeric filler to the bonding face of the recessed portion, with the elastomeric filler made of a material selected from the group comprising thermoplastic elastomeric material, rubber, high molecular polymeric material, and polyurethane.

17. The golf club head as claimed in claim 1 with the bonding face extending from the crown toward at least one of a toe and a heel, and bending to form at least one of a toe-side sidewall portion and a heel-side sidewall portion.
