Abstract

A golf club head includes a body and at least one transparent cover. The body includes a striking face for striking golf balls and a hosel for coupling with a shaft. The body includes a crown in which at least one opening is defined. A perimeter delimiting the opening includes a stepped portion. The transparent cover is securely mounted to the opening of the crown. The transparent cover is made of a transparent material having a specific gravity smaller than 1.5 g/cm³ for reducing a weight of the crown of the golf club head and for shifting a center of gravity of the golf club head downward and rearward.

Claims

1. A golf club head comprising:

a body including a striking face for striking golf balls and a hosel adapted to couple with a shaft, the body including a crown, at least one opening being defined in the crown, a perimeter delimiting the opening including a stepped portion; and

at least one transparent cover securely mounted to said at least one opening of the crown, said at least one transparent cover being made of a transparent material having a specific gravity smaller than 1.5 g/cm³ for reducing a weight of the crown of the golf club head and for shifting a center of gravity of the golf club head downward and rearward.

2. The golf club head as claimed in claim 1, with the body further including at least one chamber in a rear portion of a sole of the body, and with at least one weight member being mounted in said at least one chamber.

3. The golf club head as claimed in claim 1, with said at least one opening extending from the crown toward a toe of the body.

4. The golf club head as claimed in claim 1, with said at least one opening extending from the crown toward a heel of the body.

5. The golf club head as claimed in claim 1, with said at least one opening extending from the crown toward a sole of the body.

6. The golf club head as claimed in claim 1, with said at least one transparent cover being made of one of crystalline engineering plastic and non-crystalline engineering plastic.

7. The golf club head as claimed in claim 6, with the transparent cover being made of a material selected from the group comprising polyetherimide (PEI), polyethersulfone (PES), polyphenylene sulfide (PPS), polyphthalamide (PPA), polyetherketone (PEK), and polyether ether ketone (PEEK).

8. The golf club head as claimed in claim 1, with the body including a compartment delimited by an inner wall, with a marking area being provided on the inner wall.

9. The golf club head as claimed in claim 8, with the marking area being formed by one of ink printing, water jet engraving, mechanical engraving, laser engraving, sanding, sticking, and integral casting.

10. The golf club head as claimed in claim 1, with said at least one transparent cover including an inner face, and with a marking area being provided on the inner face of said at least one transparent cover.

11. The golf club head as claimed in claim 10, with the marking area being formed by one of ink printing, laser engraving, sanding, sticking, and integral molding injection.

12. The golf club head as claimed in claim 1, with said at least one opening including an extension rib extending from the stepped portion.

13. The golf club head as claimed in claim 12, with a marking area being provided on an outer face of the extension rib.

14. The golf club head as claimed in claim 13, with the marking area being formed by one of ink printing, water jet engraving, mechanical engraving, laser engraving, sanding, sticking, and integral casting.

15. The golf club head as claimed in claim 1, with said at least one transparent cover having a color.

16. The golf club head as claimed in claim 1, with said at least one transparent cover being convex.

17. The golf club head as claimed in claim 1, with said at least one transparent cover being concave.

18. The golf club head as claimed in claim 8, with the body further including at least one chamber in a rear portion of a sole of the body, and with at least one weight member being mounted in said at least one chamber.

19. The golf club head as claimed in claim 10, with the body further including at least one chamber in a rear portion of a sole of the body, and with at least one weight member being mounted in said at least one chamber.

20. The golf club head as claimed in claim 12, with the body further including at least one chamber in a rear portion of a sole of the body, and with at least one weight member being mounted in said at least one chamber.
