Abstract

A golf putter system including features that allow customization of the overall weight of the putter head, as well as the distribution of the weight. The golf putter includes a shaft and a head that is attached to an end of the shaft. The head typically includes an elongated body including a front face having a substantially flat putting surface adapted to strike a golf ball on a ball striking area disposed on the putting surface. The system normally includes a plurality of elongated end members that are releasably attachable adjacent each end of the body. The end members, when attached, may allow a user to configure the overall weight of the head and may allow a user to configure the location of the center of mass of the head. The end members generally include a rear portion that, when attached, extends beyond a rear surface of the body, axes that are substantially perpendicular to a longitudinal axis of the putting face when attached, as well as, end sight lines that mark the axes of the end members. When the end members are attached to the head, the end sight lines are typically spaced apart by a width that is similar to the diameter of a golf hole. Other embodiments are herein described.

Claims

1. A golf putter comprising:

an elongated shaft; and

a head that is attached to the shaft, the head including;

an elongated body extending along a body axis and including a front face having a substantially flat putting surface substantially parallel to the body axis and adapted to strike a golf ball on a ball striking area disposed on the putting surface;

an elongated central member that extends rearward from the body in the proximity of the ball striking area, the central member having a central axis that is substantially perpendicular to a longitudinal axis of the putting face, the central member also having a width that is similar to the diameter of a golf ball;

two elongated end members removably mounted laterally to each end of the body, the end members having axes that are substantially perpendicular to the longitudinal axis of the putting face and a rear portion that extends beyond a rear surface of the body;

a central sight line that marks the central axis of the central member; and

two end sight lines that mark the axes of the end member, the end sight lines being spaced apart by a width that is similar to the diameter of a golf hole.

2. The golf putter of claim 1, wherein the head further includes one or more cavities exposed by the removal of one or both of the elongated end members and adapted to receive one or more weights that allow a user to configure the location of the center of mass of the head and that allow a user to configure the overall weight of the head.

3. The golf putter of claim 1, wherein the end members are fabricated from a different material than the body.

4. The golf putter of claim 1, wherein the end members each include a substantially flat top surface that extends above a top surface of the body when the end member Is mounted to the body.

5. The golf putter of claim 1, wherein each end member is selected from a plurality of end members, each end member of the plurality being adapted, when removably mounted laterally to each end of the body, to provide the head with one of a different weight and a different weight distribution than any other end member in the plurality of end members.

6. A golf putter head comprising:

at least one opening that is adapted to receive an end of a shaft;

an elongated body extending along a body axis and including a front face having a substantially flat pulling surface substantially parallel to the body axis and adapted to strike a golf ball on a ball striking area disposed on the putting surface;

an elongated central member that extends rearward from the body in the proximity of the ball striking area, the central member having a central axis that is substantially perpendicular to a longitudinal axis of the putting face, the central member also having a width that is similar to the diameter of a golf ball;

two elongated end members that are removably mounted laterally to each end of the body, the end members having axes that are substantially perpendicular to the longitudinal axis of the pulling face and a rear portion that extends beyond a rear surface of the body;

a central sight line that marks the central axis of the central member; and

two end sight lines that mark the axes of the end member, the end sight lines being spaced apart by a width that is similar to the diameter of a golf hole.

7. The golf putter head of claim 6, wherein the head further includes one or more cavities exposed by the removal of one or both of the elongated end members and adapted to receive one or more weights that allow a user to configure the location of the center of mass of the head and that allow a user to configure the overall weight of the head.

8. The golf putter head of claim 6, wherein the end members are fabricated from a different material than the body.

9. The golf putter head of claim 6, wherein the end members each include a substantially flat top surface that extends above a top surface of the body when the end member is mounted to the body.

10. The golf putter head of claim 6, wherein each end member is selected from a plurality of end members, each end member of the plurality being adapted, when removably mounted laterally to each end of the body, to provide the head with one of a different weight and a different weight distribution than any other end member in the plurality of end members.

11. A golf putter system comprising:

a shaft;

a head that is attached to an end of the shaft, the head extending along a body axis and including an elongated body including a front face having a substantially flat putting surface extending substantially parallel to the body axis and adapted to strike a golf ball on a ball striking area disposed on the putting surface; and

a plurality of elongated end members that are releasably attachable laterally to each end of the body, the end members, when attached to the body, allowing a user to configure the overall weight of the head and allowing a user to configure the location of the center of mass of the head, the end members including;

a rear portion that, when attached, extends beyond a rear surface of the body,

axes that are substantially perpendicular to a longitudinal axis of the putting face when attached, and

end sight lines that mark the axes of the end members, the end sight lines being spaced apart by a width that is similar to the diameter of a golf hole when the end members are attached to the head.

12. The golf putter system of claim 11, wherein, when the putter is held in a putting position, the putting surface forms an angle between approximately 0 and 6 degrees with a substantially vertical plane.

13. The golf putter system of claim 11, wherein the ball striking area is disposed at a midpoint of the putting surface.

14. The golf putter system of claim 11, wherein the end sight line markings include ridges that are raised above the top surfaces of the end members.

15. The golf putter system of claim 11, wherein the end sight line markings include grooves that are recessed below the top surfaces of the end members.

16. The golf putter system of claim 11, wherein the head has a center of mass, and wherein the center of mass of the head is disposed behind the ball striking area.

17. The golf putter system of claim 11, wherein the center of mass of the head is disposed closer to a top surface of the head than to a bottom surface of the head.

18. The golf putter system of claim 11, wherein at least one end member is fabricated from a different material than the body.

19. The golf putter system of claim 11, wherein the end members include a substantially flat top surface that extends above a top surface of the body when the end member is attached to the body.
