Abstract
Abstract A golf putter having an elongate head connected to a shaft. The shaft has a shank with a handgrip adjacent its upper end, an offset portion connected to the lower end of the shank and extending generally transversely thereof, and a depending portion projecting from the other end of the offset portion and connected to the head. The depending portion is connected to the head at a point which is adjacent the longitudinal center of the head and preferably transversely between the longitudinal centerline and the back of the head. Preferably the offset portion is inclined upwardly from the depending portion with respect to the longitudinal axis of the head and toward the front of the head at an angle of 10°-30° relative to the longitudinal axis of the head. Preferably the upper portion of the handgrip is inclined with respect to the shank toward the player and the ball striking face of the head.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
184 words
A putter golf club comprising a head constructed and arranged so that when oriented to hit a golf ball such head is elongated generally horizontally and the longitudinal axis of such head extends generally horizontally, a front face on said head for striking a golf ball, said front face extending substantially parallel to said longitudinal axis, a shaft having an elongate shank portion, an elongate offset portion extending generally transversely of and fixed to such shank portion adjacent the lower end of such shank portion, and a depending portion fixed to and extending from said offset portion at a point remote from the connection of said offset portion of said shank, said depending portion being generally transverse to the longitudinal axis and connected to said head at the top of said head at a point on said head intermediate the longitudinally elongate extent of said head, said head being fixed to said depending portion, and said elongate offset portion being inclined toward said front face at an acute included angle to said longitudinal axis of said head in the range of 10° to 30°.
Claim 2
Dependent Claim
184 words
A putter golf club comprising a head constructed and arranged so that when oriented to hit a golf ball such head is elongated generally horizontally and the longitudinal axis of such head extends generally horizontally, a front face on said head for striking a golf ball, said front face extending substantially parallel to said longitudinal axis, a shaft having an elongate shank portion, an elongate offset portion extending generally transversely of and fixed to such shank portion adjacent the lower end of such shank portion, and a depending portion fixed to and extending from said offset portion at a point remote from the connection of said offset portion of said shank, said depending portion being generally transverse to the longitudinal axis and connected to said head at the top of said head at a point on said head intermediate the longitudinally elongate extent of said head, said head being fixed to said depending portion, and said elongate offset portion being inclined toward said front face at an acute included angle to said longitudinal axis of said head in the range of 10° to 30°.
Claim 3
Dependent Claim
