Abstract

A golf putter including a shaft and an integral ball striking head so configured that a player utilizing the putter is automatically caused to place his hands on the handle of the shaft in a region forward of the ball about to be struck. For this purpose, the ball striking head is provided with a pair of parallel lower base elements transverse to the longitudinal axis of the shaft, one adjacent to a forward face of the club head, and one adjacent to the rearward face of the club head. When the shaft is in an upright position and the rearward lower base element engages the ground, the forward lower base element is spaced from the ground. In this situation, gravity tends to cause the shaft to rotate forwardly and downwardly about the rearward lower base element resulting in simultaneous movement of the foward lower base element toward engagement with the ground. At such point that the forward and rearward lower base elements simultaneously engage the ground, the forward face of the club head is preferably inclined backward from the vertical within a range of approximately 0° to 4°.

Claims

1. A golf putter comprising:

a shaft having upper and lower ends and a longitudinal axis;

a ball striking head mounted to said lower end of said shaft being generally defined by a forward member for striking a ball lying on the ground and a rear member opposite said forward member, said rear member terminating at a rear base which extends transverse of the longitudinal axis of said shaft, said foward member terminating at a forward base which extends transverse of the longitudinal axis of said shaft, said forward base and said rear base defining between them a channel which extends transverse of the longitudinal axis of said shaft and generally parallel to said forward base and said rear base, an extremity of said forward base being nearer to said upper end of said shaft than an extremity of said rear base such that when said shaft is in an upright position and said rear base engages the ground, gravity tends to cause said shaft to rotate forwardly and downwardly about said rear base with said forward base tending to move toward engagement with the ground.

2. A golf putter as set forth in claim 1 wherein said forward member includes a planar ball striking face lying in a plane positioned within a range of 0°

to 4°

back from the vertical when said forward base and said rear base both engage the ground.

3. A golf putter as set forth in claim 2 wherein said shaft includes a gripping handle adjacent said upper end, said gripping handle being positioned forward of said ball striking face when said forward base and said rear base both engage the ground.

4. A golf putter as set forth in claim 1 wherein said rear base terminates at a rear base surface and wherein said forward base terminates at a forward base surface, said forward base surface and said rear base surface each being planar and generally parallel to the ground when said shaft is in an upright position.

5. A golf putter as set forth in claim 1 wherein said rear base terminates at a rear base surface and wherein said forward base terminates at a forward base surface, said forward base surface and said rear base surface being planar and lying generally in a plane of the ground when said forward base and said rear base both engage the ground.

6. A golf putter as set forth in claim 1 wherein said rear base terminates at a rear base surface and wherein said forward base terminates at a forward base surface, said forward base surface and said rear base surface being curved and tangent to a plane of the ground when said forward base and said rear base both engage the ground.

7. A golf putter as set forth in claim 1 wherein said forward member includes a planar ball striking face and said rear member includes a rear outer surface, said ball striking face terminating at a forward lower edge, said rear outer surface terminating at a rear lower edge, said forward lower edge being nearer to said upper end of said shaft than said rear lower edge.

8. A golf putter as set forth in claim 1 wherein said forward member includes a planar ball striking face terminating at a forward base and wherein said rear member includes a rear outer surface terminating at a rear base, said ball striking head including end surfaces intersecting with said ball striking face and with said rear outer surface, portions of said forward base and of said rear base being generally planar and portions thereof being relieved adjacent said end surfaces.

9. A golf putter as set forth in claim 1 wherein said ball striking head includes a web portion extending generally transverse of said shaft for receiving said lower end of said shaft, said forward member being integral with said web portion and wherein said rear member includes a generally u-shaped wire element having spaced apart side portions depending from said web portion and a bight portion, being said rear base, extending between said side portions.
