Golf club putter head

Abstract

A golf putter head has a weighted heel portion and a lighter front portion, where a striking face is located. A cutout is formed in the striking face and a high-impact polymer wedge-shaped insert is fitted into this cutout. The insert serves as the hitting face of the putter head. The bottom surface of the putter head has an irregularly-shaped cutout configured to receive a metal sole plate therein. Heavier portion of the sole plate is located in the heel portion of the putter head, causing a lower center of gravity of the putter head. The bottom surface of the bottom cutout adjacent to the front portion has several openings, which receive epoxy of similar lightweight material, thereby making the front portion lighter in comparison to the heel portion. The front striking surface ahs a lower inclined portion to improve loft of the putter head.

         9 . The device of  claim 1 , wherein said sole plate if formed from a material having a specific weight substantially greater than the specific weight of the putter head body.  
     
     
         10 . The device of  claim 1 , wherein said sole plate has a reduced thickness portion located in a front part of said sole plate.  
     
     
         11 . The device of  claim 1 , wherein said striking face has a bottom edge and an inclined portion adjacent said bottom edge.  
     
     
         12 . The device of  claim 11 , wherein said inclined portion is inclined at an angle of about 35 to 37 degrees in relation to the bottom edge.  
     
     
         13 . The device of  claim 1 , wherein said cutout formed in said striking face is defined in part by a pair of opposing inclined walls extending from a lower portion of said striking face to the top face of the putter head body.  
     
     
         14 . The device of  claim 11 , wherein each of said inclined walls is oriented at about 78 degree angle in relation to the bottom edge of the striking face cutout.  
     
     
         15 . A golf club putter head, comprising: 
 a generally triangular body formed from a material having a specific weight, said body comprising a striking face, a pair of side faces extending on opposite sides of said striking face, a top face and a bottom face;    a sole plate fitted into a cutout formed in the bottom face;    a hard-impact hitting plate fitted into a cutout formed in the striking face; and    a weight member mounted in the top face to facilitate weight distribution towards a heel portion of the putter head.    
     
     
         16 . The device of  claim 15 , wherein a cutout is formed in a center of said striking face, and wherein a hard-impact hitting plate is fitted in the striking face cutout.  
     
     
         17 . The device of  claim 16 , wherein said hitting plate is formed from a hard-impact polymer material.  
     
     
         18 . The device of  claim 15 , wherein said putter head body has rounded corners, one of said corners defining a heel portion of the putter head, said heel portion being located opposite said striking face.  
     
     
         19 . The device of  claim 15 , wherein the cutout formed in the bottom face comprises a bottom surface, and wherein a plurality of openings are formed in said bottom surface, said openings being filled with a material having a specific weight smaller than the specific weight of the material forming the putter head body.  
     
     
         20 . The device of  claim 19 , wherein said bottom face openings are located adjacent the striking face of the putter head body.  
     
     
         21 . The device of  claim 15 , wherein a hosel opening is formed in the top face of the putter head body.  
     
     
         22 . The device of  claim 21 , wherein said hosel opening extends perpendicularly to the top face of said putter head body.  
     
     
         23 . The device of  claim 21 , wherein said hosel opening extends at an angle to a vertical center axis of said putter head body.
