Abstract

A golf club head including a plurality of face support tabs that are attached to an interior surface of the perimeter of a golf club head. The face support tabs are in contact with a rear surface of a striking face and, in some examples, are fastened to the rear surface of the striking face. Where the face support tabs are fastened to the rear surface of the striking face, the edges of the striking face are not directly fastened to the perimeter of the golf club head. Where the face support tabs are not secured to the rear surface of the striking face, the striking face is fastened to the perimeter of the club head body and the face support tabs are preloaded so as to exert a force against the rear surface of the striking face even when the striking face is in a neutral position.

Claims

1. A golf club head comprising:

a club head perimeter comprising a toe portion, a heel portion, a topline, and a sole portion;

a shelf defined by an interior of the club head perimeter;

a striking face having a rear surface resting on the shelf; and

a plurality of face support tabs including;

a first pre-loaded face support tab extending from a first position of an interior surface of the club head perimeter adjacent the shelf and towards the rear surface of the striking face at an angle of less than about 60 degrees, wherein the first position is offset from the shelf; and

a second pre-loaded face support tab extending from a second position of the interior surface of the club head perimeter adjacent the shelf and towards the rear surface of the striking face at an angle of less than about 60 degrees, wherein the second position is offset from the shelf.

2. The golf club head of claim 1, wherein the plurality of face support tabs further includes a third face support tab and a fourth face support tab, wherein each of the face support tabs is in contact with the rear surface of the striking face.

3. The golf club head of claim 1, wherein the plurality of face support tabs are cantilevered face support tabs secured to the interior surface of the club head perimeter, and wherein each of the plurality of cantilevered face support tabs is in contact with but not secured to the rear surface of the striking face.

4. The golf club head of claim 3, wherein each of the plurality of cantilevered face support tabs has a thickness of about 1 mm to about 2 mm.

5. The golf club head of claim 1, wherein each of the plurality of face support tabs is secured to the rear surface of the striking face and to the interior surface of the club head perimeter.

6. The golf club head of claim 5, wherein each of the plurality of face support tabs has a thickness of at least about 3 mm.

7. The golf club head of claim 5, further comprising a gasket disposed between a perimeter of the striking face and the club head perimeter, wherein the perimeter of the striking face is not directly fastened to the club head perimeter.

8. The golf club head of claim 1, wherein the angle between the first face support tab and the rear surface of the striking face is between about 45 degrees to 60 degrees.

9. A golf club head comprising:

a club head perimeter comprising a toe portion, a heel portion, a topline, and a sole portion;

a striking face having a rear surface resting against an interior surface of the club head perimeter; and

a plurality of cantilevered face support tabs, wherein each of the plurality of cantilevered face support tabs is secured to and extends from a position adjacent to and offset from the interior surface to the rear surface of the striking face at an angle less than about 60 degrees, wherein each of the plurality of cantilevered face support tabs is not secured to the striking face and is pre-loaded such that each of the plurality of cantilevered face support tabs applies pressure against the rear surface of the striking face, wherein each of the plurality of cantilevered face support tabs contacts the rear surface of the striking face at a different location.

10. The golf club head of claim 9, wherein a perimeter of the striking face is welded to the club head perimeter.

11. The golf club head of claim 10, wherein each of the plurality of cantilevered face support tabs is in contact with the rear surface of the striking face but is not fastened to the rear surface of the striking face.

12. The golf club head of claim 9, wherein each of the plurality of cantilevered face support tabs has a thickness of about 1 mm to about 2 mm.

13. The golf club head of claim 9, wherein the angle is between about 45 degrees to 60 degrees.

14. The golf club head of claim 9, wherein the plurality of cantilevered face support tabs includes:

a first cantilevered face support tab at the toe portion, the first cantilevered face support tab having a width between about one-half to three-quarters of a height of the toe portion;

a second cantilevered face support tab at the topline, the second cantilevered face support tab having a width between about one-half to three-quarters a length of the topline;

a third cantilevered face support tab at the heel portion, the third cantilevered face support tab having a width between about one-half to three-quarters a height of a heel edge of the heel portion; and

a fourth cantilevered face support tab at the sole portion, the fourth cantilevered face support tab having a width between about one-half to three-quarters a length of the sole portion.

15. A golf club head comprising:

a club head perimeter comprising a toe portion, a heel portion, a topline, and a sole portion;

a shelf defined by an interior surface of the club head perimeter;

a striking face having a rear surface resting on the shelf; and

a plurality of face support tabs, wherein each of the plurality of face support tabs is secured to a position adjacent to and offset from the shelf on the interior surface of the club head perimeter and to the rear surface of the striking face, so as to suspend the striking face relative to the club head perimeter, wherein the tab extends from the offset position to the rear surface of the striking face at an angle less than about 60 degrees.

16. The golf club head of claim 15, wherein the angle is between about 45 degrees to 60 degrees.

17. The golf club head of claim 15, wherein a perimeter of the striking face is not secured to the club head perimeter.

18. The golf club head of claim 17, further comprising a gasket disposed between the perimeter of the striking face and the club head perimeter.

19. The golf club head of claim 15, wherein the plurality of face support tabs includes a first face support tab at the toe portion, a second face support tab at the topline, a third face support tab at the heel portion, and a fourth face support portion at the sole portion.

20. The golf club head of claim 15, wherein a thickness of each of the plurality of face support tabs is between 2-6 mm.
