Abstract

A golf putter head having a body having a striking face, a top portion, a bottom portion, a toe portion, and a heel portion. The putter head further has at least one weight member connectable to the body at a predetermined location on the body such that the golf putter head has a first center of gravity. The at least one weight member is repositionable with respect to and connectable to the body such that repositioning the weight member and connecting the weight member to the body at the predetermined location on the body causes the golf putter head to have second center of gravity that is different both horizontally and vertically from the first center of gravity.

Claims

1. A golf putter head comprising:

a body having a striking face, a top portion, a bottom portion, a toe portion, and a heel portion; and

at least one weight member comprising a post and a weight, the post being connectable to the body at a predetermined location on the body;

wherein the weight is positionable about an axis of rotation at the post to a first position connected to the body at the predetermined location on the body, thereby causing the putter head to have a first center of gravity location; and

wherein the weight is further positionable about the axis of rotation to a second position connected to the body at the predetermined location on the body, thereby causing the putter head to have a second center of gravity location that is different both horizontally and vertically from the first center of gravity location.

2. The golf putter head of claim 1 comprising two weight members and two predetermined locations on the body.

3. The golf putter head of claim 2 wherein one of the predetermined locations on the body is on the heel portion and is closer to the heel of the body than to the center of the body and the other of the predetermined locations on the body is on the toe portion and is closer to the toe of the body than to the center of the body.

4. The golf putter head of claim 2 wherein the weight of each of the two weight members is positionable such that the two weights in combination have a first position with respect to the body, thereby causing the putter head to have the first center of gravity location, and wherein each of the two weights is positionable such that the weights in combination have a second position with respect to the body, thereby causing the putter head to have a second center of gravity location that is different both horizontally and vertically from the first center of gravity location.

5. The golf putter head of claim 2 wherein the golf putter head has a first sweet spot when the two weights in combination have a first position with respect to the body and a second sweet spot when the two weights in combination have a second position with respect to the body, and wherein the second sweet spot is different in dimension horizontally from the first sweet spot.

6. The golf putter head of claim 1 wherein the length of the post is generally orthogonal to and extends rearward from the striking face.

7. The golf putter head of claim 1 further comprising an arm connecting the weight and the post.

8. The golf putter head of claim 7 wherein the weight, arm and post are integrally formed.

9. The golf putter head of claim 1 wherein the first position and second position each correspond to one of a plurality of predefined weight positions.

10. The golf putter head of claim 9 wherein the predefined weight positions correspond to detents at the predetermined location on the body.

11. The golf putter head of claim 1 wherein the at least one weight is repositionable with respect to the body while the post connected to the body.

12. The golf putter head of claim 1 wherein the weight is movable with respect to the post.

13. The golf putter head of claim 1 wherein the body is at least partially composed of a first material and the weight member is at least partially composed of a second material that has a higher density than the first material.

14. The golf putter head of claim 1 further comprising at least one alignment aid.

15. The golf putter head of claim 14 wherein the at least one of alignment aid comprises a line generally perpendicular to the striking face.

16. The golf putter head of claim 1 wherein the at least one weight member is positionable with respect to the body such that the at least one weight member contacts a ground surface when the putter head is grounded, thereby changing a lie angle of the putter head by preventing at least part of the bottom portion of the body from contacting the ground surface when the putter head is grounded.

17. A golf putter head comprising:

a body having a striking face, a top portion, a bottom portion, a toe portion, and a heel portion; and

at least one weight member connectable to the body at a predetermined location on the body such that the golf putter head has a first center of gravity;

wherein the at least one weight member is repositionable with respect to and connectable to the body such that repositioning the weight member and connecting the weight member to the body at the predetermined location on the body causes the golf putter head to have second center of gravity that is different both horizontally and vertically from the first center of gravity.

18. The golf putter head of claim 17 comprising two weight members and two predetermined locations on the body.

19. The golf putter head of claim 18 wherein one of the predetermined locations on the body is on the heel portion and is closer to the heel of the body than to the center of the body and the other of the predetermined locations on the body is on the toe portion and is closer to the toe of the body than to the center of the body.

20. The golf putter head of claim 18 wherein each of the two weight members is positionable such that the two weight members in combination have a first position with respect to the body, thereby causing the putter head to have the first center of gravity location, and wherein each of the two weight members is positionable such that the two weight members in combination have a second position with respect to the body, thereby causing the putter head to have a second center of gravity location that is different both horizontally and vertically from the first center of gravity location.

21. The golf putter head of claim 18 wherein the golf putter head has a first sweet spot when the two weights in combination have a first position with respect to the body and a second sweet spot when the two weights in combination have a second position with respect to the body, and wherein the second sweet spot is different in dimension horizontally from the first sweet spot.

22. The golf putter head of claim 17 wherein the at least one weight member is positionable with respect to the body the golf putter head such that the putter head comprises a center of gravity that is further from the ground than a center of gravity of a golf ball when the putter head and the golf ball are grounded.

23. The golf putter head of claim 17 wherein the at least one weight member is positionable with respect to the body the golf putter head such that the bottom portion of the body is not in contact with the ground when the golf putter head is grounded.

24. The golf putter head of claim 17 wherein the at least one weight member is repositionable with respect to the body such that the at least one weight member contacts a ground surface when the putter head is grounded, thereby changing a lie angle of the putter head by preventing at least part of the bottom portion of the body from contacting the ground surface when the putter head is grounded.

25. A golf putter head comprising:

a body having a striking face, a top portion, a bottom portion, a toe portion, and a heel portion; and

at least two weight members connectable to the body at predetermined locations on the body such that the golf putter head has a first sweet spot and a first center of gravity;

wherein the at least two weight members are repositionable with respect to and connectable to the body at the predetermined locations on the body such that repositioning the weight members and connecting the weight members to the body at the predetermined locations on the body causes the golf putter head to have a second center of gravity that is different vertically from the first center of gravity and further causes the golf putter head to have a second sweet spot that is different in dimension horizontally from the first sweet spot.
