Abstract

A golf putter head with a front edge is used for striking a golf ball in an essentially linear contact area horizontal to the ground when putting and an opposed back edge. A length is defined between a toe edge which extends from the front edge to the back edge of the blade and an opposed heel edge, and a thickness is defined between a top side bordered by the edges and an opposed bottom side. The golf putter includes a non-horizontal groove on the front edge at least adjacent to a ball contact portion of the head defined by a non-horizontal projection perpendicular to the tangent of the arc of the face of the putter head corresponding to the non-horizontal groove perpendicular to the tangent of the arc of the face of the putter head.

Claims

exact text as granted — not AI-modified
1 . In a golf putter head with a front edge used for striking a golf ball in an essentially linear contact area horizontal to the ground when putting and an opposed back edge, a length defined between a toe edge which extends from the front edge to the back edge of the blade and an opposed heel edge, and a thickness defined between a top side bordered by the edges and an opposed bottom side, the improvement which comprises a non-horizontal groove on the front edge at least adjacent to a ball contact portion of the head defined by a non-horizontal projection substantially perpendicular to the tangent of the arc of the face of the putter head corresponding to the non-horizontal groove substantially perpendicular to the tangent of the arc of the face of the putter head.  
   
   
       2 . The putter head of  claim 1  wherein the front edge defines a substantially flat face to strike the golf ball.  
   
   
       3 . The putter head of  claim 1  wherein the groove is substantially slanted with respect to the vertical.  
   
   
       4 . The putter head of  claim 3  wherein said slanted groove is slanted toward a heel of said golf putter head.  
   
   
       5 . The putter head of  claim 3  wherein the slanted groove is slanted toward a toe of said golf putter head.  
   
   
       6 . The putter head of  claim 1  wherein the groove has a width of no more than 0.07 inches.  
   
   
       7 . The putter head of  claim 1  wherein the groove has a have a width of 0.05-0.07 inches.  
   
   
       8 . The putter head of  claim 1  wherein the putter face has a radius of three inches or less.  
   
   
       9 . The putter head of  claim 3 , wherein the slanted groove defines a slanted projection.  
   
   
       10 . The putter head of  claim 1  wherein the groove is substantially oval shaped.  
   
   
       11 . In a golf putter head with a front edge used for striking a golf ball in an essentially linear contact area horizontal to the ground when putting and an opposed back edge, a length defined between a toe edge which extends from the front edge to the back edge of the blade and an opposed heel edge, and a thickness defined between a top side bordered by the edges and an opposed bottom side, the improvement which comprises a non-horizontal groove on the front edge at least adjacent to a ball contact portion of the head defined by a first non-horizontal projection substantially parallel to a second non-horizontal projection.  
   
   
       12 . The putter head of  claim 11  wherein the front edge defines a substantially flat face to strike the golf ball.  
   
   
       13 . The putter head of  claim 11  wherein the groove is substantially slanted with respect to the vertical.  
   
   
       14 . The putter head of  claim 13  wherein said slanted groove is slanted toward a heel of said golf putter head.  
   
   
       15 . The putter head of  claim 13  wherein the slanted groove is slanted toward a toe of said golf putter head.  
   
   
       16 . The putter head of  claim 11  wherein the groove has a width of no more than 0.07 inches.  
   
   
       17 . The putter head of  claim 11  wherein the groove has a have a width of 0.05-0.07 inches.  
   
   
       18 . The putter head of  claim 11  wherein the putter face has a radius of three inches or less.  
   
   
       19 . The putter head of  claim 13 , wherein the slanted groove defines a slanted projection.  
   
   
       20 . The putter head of  claim 10  wherein the groove is substantially oval shaped.
