Abstract

A set of golf clubs including golf club heads having improved mass distribution characteristics. The set includes golf club heads having a club head main body including a hitting face and a face support, a muscle back shell and a weight insert.

First claim

We claim:

1. A golf club head, comprising:
a club head main body, wherein the club head main body comprises a hitting face that defines a forward ball-striking surface and a rear surface that is spaced from the ball-striking surface by a face thickness, wherein the main body further comprises a face support protruding rearward from the rear surface;
a frame coupled to a lower portion of the club head main body, wherein the frame comprise a sole portion, a back flange and a support extension, wherein the sole portion of the frame forms at least a portion of a sole surface of the golf club head, wherein the back flange extends upward from a rearward end of the sole portion, and wherein the support extension is disposed at an upward end of the back flange; and
an extension member that extends between the support extension of the frame and the hitting face, wherein the extension member abuts a portion of the face support of the hitting face so that a force is applied to the face support.

2. The golf club head of claim 1 , wherein the extension member is movably coupled to the support extension.

3. The golf club head of claim 2 , wherein the extension member is threaded to the support extension.

4. The golf club head of claim 1 , wherein the club head main body further comprises a partial sole extend rearward from a lower end of the hitting face, and wherein the face support protrudes rearward from the hitting face by a greater distance than the partial sole extends rearward from the hitting face.

5. The golf club head of claim 1 , wherein the face support extends across a portion of the hitting face in a generally heel to toe direction and supports the hitting face to maintain the mechanical integrity of hitting face.

6. The golf club head of claim 1 , further comprising a plurality of extension members extending between the support extension of the frame and the hitting face.

7. The golf club of claim 6 , wherein each of the plurality of extension members abuts a portion of the face support of the hitting face so that force is applied to the face support.

8. The golf club of claim 7 , wherein the extension members are movably coupled to the support extension.

9. A golf club head, comprising:
a club head main body comprising a club head main body, a face support, and a sole portion, wherein the hitting face defines a forward ball-striking surface and a rear surface that is spaced from the ball-striking surface by a face thickness, wherein the face support protrudes rearward from the rear surface, wherein the sole portion extends rearward from a lower edge of the hitting face where it forms a leading edge of the golf club head; and
a frame coupled to the sole portion of the club head main body, wherein the frame extends between a trailing edge of the sole portion and the face support,
wherein the frame is sized so that the frame is in compression between the sole portion and the face support to apply a force to the rear surface of the hitting face.

10. The golf club head of claim 9 , wherein the frame comprises a back flange that extends upward from the sole portion and a support extension that extends between an upper end of the back flange and the face support.

11. The golf club head of claim 9 , wherein the back flange defines an insert recess, wherein the frame further comprises a back flange insert disposed in the insert recess.

12. The golf club head of claim 11 , wherein the back flange insert is constructed from a material having a density that that is greater than the density of a material of the frame.

13. The golf club head of claim 9 , wherein the frame defines a bumper recess at the interface between the back flange and the support extension, wherein the frame further comprises a bumper insert disposed in the bumper recess.

14. The golf club head of claim 13 , wherein the frame as an L-shaped cross-sectional shape and the bumper insert is disposed at a rear corner of the frame.

15. A golf club head, comprising:
a club head main body comprising a club head main body, a face support, a sole portion, and a back flange, wherein the hitting face defines a forward ball-striking surface and a rear surface that is spaced from the ball-striking surface by a face thickness, wherein the face support protrudes rearward from the rear surface, wherein the sole portion extends rearward from a lower edge of the hitting face where it forms a leading edge of the golf club head, wherein the back flange extends upward from the sole portion; and
a support extension extends between the back flange and the face support,
wherein the club head main body is constructed from a first material having a first density, and the support extension is constructed from a second material having a second density that is lower than the first density.

16. The golf club head of claim 15 , further comprising a back flange insert disposed in a recess in an outer surface of the back flange.

17. The golf club head of claim 15 , further comprising a sole insert that forms a portion of a sole surface of the golf club head.

18. The golf club head of claim 17 , wherein the sole insert extends upward from the sole portion to a location adjacent the support extension.

19. The golf club head of claim 18 , wherein the sole insert abuts the face support.

20. The golf club head of claim 19 , wherein the sole insert is sized so that it is in compression and applies a force to the hitting face.
