Abstract

A golf putter head adapted for attachment to a club shaft is provided with a face member having a strike face and a cylindrical back cavity, and a body member configured to fit and rotate within the back cavity is disclosed. Selective rotation of the body member within the back cavity sets a loft of the putter head. The weighting of the putter is adjusted by securing a weight member to the body member. A golf putter head having an increased moments of inertia is also disclosed. The putter head includes a face member, a body member, and a weight member. Placement of the weight member is such that the moments of inertia are increased and the putter head is stable.

Claims (45)

1. A golf club head, comprising:

a face member having a strike face and a rear surface opposite said strike face;

a body member having a first end and a second end, said body member being coupled at said first end to said face member rear surface; and

a weight member having two ends and a central portion intermediate said ends, said weight member coupled to said body member second end along said weight member central portion, said weight member ends being nearer said face member than said central portion is to said face member;

wherein the club head includes a center of gravity, said center of gravity being located a distance of approximately 1 inch to approximately 4 inches from said strike face.

2. The golf club head of claim 1 , wherein said center of gravity is located a distance of approximately 1.5 inches to approximately 2 inches from said strike face.

3. The golf club head of claim 2 , wherein said center of gravity is located a distance of approximately 1.7 inches from said strike face.

4. The golf club head of claim 1 , wherein:

the club head has a length having a midpoint; and

said center of gravity is between said midpoint and said weight member.

5. The golf club head of claim 4 , wherein said center of gravity is located a distance of approximately 50% of said length to approximately 75% of said length behind said strike face.

6. The golf club head of claim 4 , further comprising a shaft mount positioned between said midpoint and said strike face.

7. The golf club head of claim 6 , wherein said shaft mount is positioned a distance of approximately 25% of said length to approximately 50% of said length behind said strike face.

8. The golf club head of claim 6 , wherein:

the club head has a weight; and

approximately 50% of said weight to approximately 75% of said weight is located on a weight member side of said shaft mount.

9. The club head of claim 6 , further comprising a shaft coupled to said shaft mount.

10. The club head of claim 9 , wherein said shaft is bent to give a straight, no offset appearance at address.

11. The golf club head of claim 1 , wherein the club head is a putter head.

12. The golf club head of claim 1 , wherein said weight member is only coupled to said body member along said weight member central portion.

13. The golf club head of claim 1 , wherein said weight member ends extend away from said body member.

14. A golf club head, comprising:

a face member having a strike face and a rear surface opposite said strike face, said strike face having a loft angle within a range of approximately 0° to approximately 10°;

a body member having a first end and a second end, said body member being coupled at said first end to said face member rear surface;

a weight member having two ends and a central portion intermediate said ends, said weight member coupled to said body member second end along said weight member central portion, said weight member ends being nearer said face member than said central portion is to said face member;

a shaft mount;

wherein the club head includes a center of gravity located a distance of approximately 1 inch to approximately 4 inches from said strike face.

15. The golf club head of claim 14 , wherein said center of gravity is located a distance of approximately 1.5 inch to approximately 2 inches from said strike face.

16. The golf club head of claim 14 , wherein said center of gravity is located a distance of approximately 1.7 inches from said strike face.

17. The golf club head of claim 14 , further comprising a shaft coupled to said shaft mount, said shaft having a length of approximately 35 inches or more.

18. The golf club head of claim 17 , wherein said length is approximately 37 inches.

19. The golf club head of claim 17 , wherein said length is approximately 53 inches.

20. The club head of claim 17 , wherein said shaft is bent to give a straight, no offset appearance at address.

21. The golf club head of claim 14 , wherein said loft angle is approximately 4° or less.

22. The golf club head of claim 14 , wherein said loft angle is approximately 3.5° or less.

23. The golf club head of claim 14 , wherein said loft angle is approximately 3° or less.

24. The golf club head of claim 14 , wherein said loft angle is a dynamic loft angle.

25. The golf club head of claim 14 , wherein:

the club head has a length; and

said shaft mount is positioned a distance of approximately 25% of said length to approximately 50% of said length behind said strike face.

26. The golf club head of claim 14 , wherein, wherein said shaft mount is offset from said face member.

27. The golf club head of claim 14 , wherein, wherein said body member comprises said shaft mount.

28. The golf club head of claim 27 , wherein, wherein said shaft mount is an integral part of said body.

29. The golf club head of claim 14 , wherein said weight member is only coupled to said body member along said weight member central portion.

30. The golf club head of claim 14 , wherein said weight member ends extend away from said body member.
