Abstract

A golf club including a club head having a club head main body including a hitting face and a face support, and a support extension. The support extension extends between the face support and a back flange to define a lower cavity.

First claim

We claim:

1. A golf club head, comprising:
a club head main body including a hitting face, a sole extending from a lower edge of the hitting face, a back flange extending upward from the sole, and a face support extending from a rear surface of the hitting face toward the back flange;
a back flange insert coupled to an outer surface of the back flange in a recess defined by the back flange; and
a support extension that extends toward the back flange from the rear surface of the hitting face,
wherein an upper portion of the club head main body is perimeter weighted and the perimeter weighted portion and face support combine to form an upper back cavity, and
wherein a hollow interior cavity is defined by a muscle portion of the golf club head.

2. The golf club head of claim 1 , wherein the face support extends partially between the hitting face and the back flange to form a gap between the face support and the back flange.

3. The golf club head of claim 2 , wherein the support extension is interposed between the face support and the back flange.

4. The golf club head of claim 2 , wherein the support extension extends across the gap between the face support and the back flange.

5. The golf club head of claim 1 , further comprising a sole insert, wherein the sole defines a lower surface and a sole recess in the lower surface, and wherein the sole insert is coupled to the main body in the sole recess.

6. The golf club head of claim 5 , wherein the main body is constructed of a first material and the sole insert is constructed of a second material, wherein the first material has a first density and the second material has a second density that is different than the first density.

7. The golf club head of claim 6 , wherein the first density is lower than the second density.

8. The golf club head of claim 6 , wherein the first density is greater than the second density.

9. The golf club head of claim 1 , further comprising a back plate including a plate portion that is coupled to the rear surface of the hitting face and fills at least a portion of the upper back cavity, and wherein the support extension is a portion of the back plate.

10. The golf club head of claim 9 , wherein the back plate includes a ring member disposed on at least a portion of the peripheral edge of the back plate.

11. The golf club head of claim 10 , wherein the ring member comprises a material having a durometer value in a range of Shore A30 to Shore A110.

12. A golf club head, comprising:
a club head main body including a hitting face, a sole extending from a lower edge of the hitting face, a back flange extending upward from the sole, and a face support extending from a rear surface of the hitting face toward the back flange;
a sole insert coupled to the main body at the sole; and
a support extension that extends toward the back flange from the rear surface of the hitting face,
wherein an upper portion of the club head main body is perimeter weighted and the perimeter weighted portion and face support combine to form an upper back cavity, and
wherein a hollow interior cavity is defined by a muscle portion of the golf club head.

13. The golf club head of claim 12 , wherein the main body is constructed of a first material and the sole insert is constructed of a second material, wherein the first material has a first density and the second material has a second density that is different than the first density.

14. The golf club head of claim 13 , wherein the first density is lower than the second density.

15. The golf club head of claim 13 , wherein the first density is greater than the second density.

16. The golf club head of claim 12 , wherein the face support extends partially between the hitting face and the back flange to form a gap between the face support and the back flange.

17. The golf club head of claim 16 , wherein the support extension is interposed between the face support and the back flange.

18. The golf club head of claim 17 , wherein the support extension extends across the gap to enclose a lower cavity of the golf club head.

19. The golf club head of claim 12 , wherein sole insert is placed in compression between the face support and the sole.

20. The golf club head of claim 12 , further comprising a second sole insert coupled to the main body at the sole, wherein the first and the second sole inserts extend between the sole and the rear surface of the hitting face.
