Abstract

A golf club (40) having a club head (42) with a face component (60), an aft body (61) and a gasket (300) is disclosed herein. The face component (60) has a striking plate portion (72) and a return portion (74). The aft-body (61) is preferably composed of a crown portion (62), a sole portion (64) and optionally a ribbon section (90). The gasket (300) provides an interface between the face (60) and the aft-body (61) that reduces corrosion and improves manufacturing costs of the club head. The club head (42) preferably has a volume in the range of 290 cubic centimeters to 600 cubic centimeters, a weight in the range of 165 grams to 300 grams, and a striking plate portion (72) surface area in the range of 4.00 square inches to 7.50 square inches.

Claims

1. A golf club head comprising:

a face component, the face component having striking plate portion and a return portion;

an aft-body having a crown portion and a sole portion, the aft-body attached to the return portion of the face component; and

a gasket positioned in a gap between the face component and the aft-body, the gasket composed of a polymer material.

3. The golf club head according to claim 1 wherein the gasket is composed of a thermoplastic polyurethane elastomer material

4. The golf club head according to claim 1 wherein the gasket has a width in the range of 0.010 inch to 0.200 inch.

5. The golf club head according to claim 1 wherein at least a portion of the gasket has a “

L”

shaped cross-section.

6. The golf club head according to claim 1 wherein at least a portion of the gasket has a wedged shaped cross-section.

7. The golf club head according to claim 1 wherein at least a portion of the gasket has a rectangular shaped cross-section.

8. The golf club head according to claim 1 wherein at least a portion of the gasket has a circular shaped cross-section.

10. The golf club head according to claim 1 wherein the gap is positioned 0.5 inch to 2.5 inches from a perimeter of the striking plate of the face component.

2. (canceled)

9. (canceled)

11. A golf club head comprising:

a face component composed of a metal material, the face component having striking plate portion and a return portion, the striking plate portion having a thickness in the range of 0.010 inch to 0.250 inch and the return portion having a thickness ranging from 0.010 inch to 0.250 inch;

an aft body comprising an upper section and a lower section, the upper section comprising a crown portion and an upper ribbon portion and the lower section comprising a sole portion and a lower ribbon portion, the aft-body composed of a metal material selected from the group consisting of magnesium alloys, aluminum alloys, magnesium and aluminum, the aft-body attached to the return portion of the face component, the aft body having a thickness ranging from 0.015 inch to 0.100 inch; and

a gasket positioned in a gap between the face component and the aft-body;

wherein the moment of inertia about the lzz axis through the center of gravity is greater than 3000 grams-centimeter squared, and the moment of inertia about the lyy axis through the center of gravity is greater than 1900 grams-centimeter squared.

12. The golf club head according to claim 11 wherein the gasket is composed of a thermoplastic polyurethane elastomer material

13. The golf club head according to claim 11 wherein the gasket has a thickness in the range of 0.010 inch to 0.200 inch.

14. (canceled)

15. A golf club head comprising:

a face component composed of a metal material, the face component having striking plate portion and a return portion, the striking plate portion having a thickness in the range of 0.010 inch to 0.250 inch;

an aft body comprising an upper section and a lower section, the upper section comprising a crown portion and an upper ribbon portion and the lower section comprising a sole portion and a lower ribbon portion, the aft-body composed of a metal material selected from the group consisting of magnesium alloys, aluminum alloys, magnesium and aluminum, the aft-body attached to the return portion of the face component, the aft body having a thickness ranging from 0.015 inch to 0.100 inch;
