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. 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.

Claims

1. A golf putter head adapted for attachment to a club shaft comprising:

a face member having a strike face and a cylindrical back cavity;

a body member configured to fit and rotate in at least one plane or direction within the back cavity, the body member including a front portion with a generally cylindrical projecting portion and a cylindrical passage extending parallel thereto;

a weight member coupled to the body member; and

a generally cylindrical insert configured and dimensioned to be received within the cylindrical passage, the insert further including a bas portion fixedly coupled to the face member;

wherein selective rotation of the body member within the back cavity sets a loft of the putter head.

2. The putter head of claim 1, wherein the weight member is symmetrically disposed about a longitudinal center of the body member.

3. The putter head of claim 2, wherein the weight member has a generally arcuate shape and is disposed on a back portion of the body member.

4. The putter head of claim 1, wherein the body member further comprises a side flange with a bore therein, the bore being configured and dimensioned to receive the shaft.

5. The putter head of claim 1, wherein the body member comprises a front portion, a back portion, and a pair of sides, the sides each having a lower edge with at least two edge portions that are crooked it respect to each other.

6. The puffer head of claim 5, wherein the edge portions are crooked at an angle of between about 0°

and about 30°

.

7. The putter head of claim 1, wherein the weight member includes a central recessed portion.

8. A golf putter head adapt d for attachment to a club shaft comprising:

a face member having a strike face and a cylindrical back cavity, the back cavity comprising two recessed wing portions and a recessed generally cylindrical portion disposed therebetween;

a body member configured to fit and rotate in at least one plane or direction within the back cavity, the body member including a front portion with a generally cylindrical projecting portion and a cylindrical passage extending parallel thereto; and

a generally cylindrical insert configured and dimensioned to be received within the cylindrical passage, the insert further including a base portion configured to be received in fixed orientation within the wing portions;

wherein selective rotation of the body member within the back cavity sets a loft of the putter head.

9. The putter head of claim 8, wherein the front portion further includes opposing sections separated by a slit that extends along the length of the cylindrical passage, the opposing sections being connected by a threaded hole.

10. The putter bead of claim 9, wherein threadable engagement of a fastener in the threaded hole changes the separation of the opposing sections.

11. A golf putter head adapted for attachment to a club shaft comprising:

a face member having a strike face and a back cavity, the back cavity including at least one keyway portion;

a body member configured to fit and rotate in at least one plane or direction within the back cavity, the body member including a passage therein; and

an insert configured to fit and rotate within the passage, the insert including at least one keyed portion,

wherein when the keyed portion is disposed in the keyway portion, selective rotation of the body member about the insert sets a loft of the putter head.

12. A golf putter head adapt d for attachment to a club shaft, comprising:

a body member having a front portion with a generally cylindrical projecting portion and a cylindrical passage extending parallel thereto;

a face member adjustably coupled to the body member, the face member having a strike face and a cylindrical back cavity configured to fit over and rotate about the projecting portion;

a weight member fixedly coupled to the body member, the weight member being symmetrically disposed about the body member.

a generally cylindrical insert configured and dimensioned to be received within the cylindrical passage and having a base portion fixedly coupled to the face member.

13. The golf putter head of claim 12, wherein:

the front portion includes opposing sections separated by a slit that extends along the length of the cylindrical passage, the opposing sections being connected by a threaded hole;

threadable engagement of a fastener in the threaded hole changes the separation of the opposing sections.
