Putter club head with radial face

Abstract

A putter club head having a radial face to impact a golf ball above the equator of the golf ball. The club head having a recessed area formed in a front surface for receipt of an insert that can be either shaped by a 10.0 inch radius, or employ an insert constructed and arranged to form the 10.0 inch radius. The insert has a frontal surface that works in combination with a recessed area to cause an immediate golf ball roll upon impact. The radial impact face insert is releasably secured to the recessed area of the putter club head, allowing ease of substitution. The radial impact face insert can vary in materials of construction, wherein a golfer can employ the insert to accommodate various golfing conditions while maintaining a single putter club.

What is claimed is: 
     
         1 . A golf putter club head comprising:
 a club head member having a front surface, a rear surface, a lower surface, and an upper surface with a hosel extending from said upper surface;   a recessed area formed in said front surface;   an insert constructed and arranged to reside in said recessed area, said insert having a radial shaped front face surface with a 10.0 inch radius curvature based from a center line positioned 0.875 inches above the lower surface of said club head;   wherein said center line of said radius is positioned above a center line of a golf ball, whereby impacting the golf ball with said club head insert imparts a forward roll of the golf ball.   
     
     
         2 . The golf putter club head according to  claim 1  wherein said curvature of said insert forms an upper thickness of about 0.150 inches and a lower thickness about 0.124 inches. 
     
     
         3 . The golf putter club head according to  claim 1  including an aperture extending from said recessed area to said rear surface. 
     
     
         4 . The golf putter club head according to  claim 3  including a fastener positioned on said rear surface and extending through said aperture for securing said insert to said recessed area. 
     
     
         5 . The golf putter club head according to  claim 1  wherein said insert is formed from a polymeric or 6061 aluminum material. 
     
     
         6 . The golf putter club head according to  claim 5  wherein said polymeric material has a 45% rebound with a 84 shore A hardness n a central section of said insert. 
     
     
         7 . The golf putter club head according to  claim 6  wherein said polymeric material has an 85% rebound with a 95 shore A hardness outside said central section. 
     
     
         8 . The golf putter club head according to  claim 1  wherein said insert includes a plurality of grooves spaced apart about 0.031 inches with a depth of about 0.015 inches deep, 
     
     
         9 . The golf putter club head according to  claim 8  wherein said ten grooves are spaced apart along the length of said insert. 
     
     
         10 . A golf putter club head comprising:
 a club head member having a front surface, a rear surface, a lower surface, and an upper surface with a hosel extending from said upper surface;   a recessed area formed in said front surface, said recessed area having a radial shaped front face surface with a 10.0 inch radius curvature based from a center line positioned 0.875 inches above the lower surface of said club head; and   an insert securable to said recessed area;   wherein said center line of said radius is positioned above a center line of a golf ball, whereby impacting the golf ball with said club head insert imparts a forward roll of the golf ball.   
     
     
         11 . The golf putter club head according to  claim 10  wherein said recessed area includes a support wall having an angle between 1 and 5 degrees. 
     
     
         12 . The golf putter club head according to  claim 10  wherein said support wall angle is about 2 degrees. 
     
     
         10 . The golf putter club head according to  claim 10  including an aperture extending from said recessed area to said rear surface. 
     
     
         14 . The golf putter club head according to claim  13  including a fastener positioned on said rear surface and extending through said aperture for securing said insert to said recessed area. 
     
     
         15 . The golf putter club head according to  claim 14  wherein said polymeric material has a 45% rebound with a 84 shore A hardness in a central section of said insert. 
     
     
         16 . The golf putter club head according to  claim 15  wherein said polymeric material has an 85% rebound with a 95 shore A hardness outside said central section. 
     
     
         17 . The golf putter club head according to  claim 15  wherein said polymeric material has an 85% rebound with a 95 shore A hardness. 
     
     
         18 . The golf putter club head according to  claim 10  wherein said insert includes a plurality of grooves spaced apart about 0.031 inches with a depth of about 0.015 inches deep. 
     
     
         19 . The golf putter club head according to  claim 18  wherein said ten grooves are spaced apart along the length of said insert. 
     
     
         20 . The golf putter club head according to  claim 10  wherein said lower surface is presented at an angle of about 91° to said front surface.
