Putter club head with an adjustable radial face

Abstract

A putter club head having an adjustable radial face. The club head having a recessed area formed in a front surface for receipt of the adjustable radial face formed by an impact surface insert. The radial impact surface insert has a frontal surface that works in combination with a radial recessed area to cause an immediate golf ball roll upon impact. The radial impact surface insert is releasably secured to the recessed area of the putter club head, allowing ease of substitution. The radial impact surface insert can vary in materials of construction, wherein a golfer can employ the radial impact surface 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 an upper surface, a lower surface, a front surface, and a rear surface;   a recessed area formed in said front surface, said recessed area having a negative loft and at least one aperture extending from said recessed area to said rear surface;   a radial impact surface insert constructed and arranged to reside in said recessed area, said radial impact surface insert maintaining said negative loft between said upper surface and said lower surface; and   a fastener positioned on said rear surface and extending through said aperture securing said radial impact surface insert to said recessed area;   wherein negative loft of said recessed area is constructed and arranged to provide forward golf ball upon impact.   
     
     
         2 . The golf putter club head according to  claim 1  wherein said recessed area includes a support wall having an angle between 1 and 5 degrees to provide said negative loft. 
     
     
         3 . The golf putter club head according to  claim 1  wherein said negative loft is about 2 degrees. 
     
     
         4 . The golf putter club head according to  claim 1  wherein said lower surface is presented at an angle of about 91° to said front surface. 
     
     
         5 . The golf putter club head according to  claim 1  wherein said radial impact surface insert includes a foil positioned between said radial impact surface insert and said recessed area providing a tactile sound when a golf ball is impacted. 
     
     
         6 . The golf putter club head according to  claim 1  wherein said radial impact surface insert is constructed of a polymeric material. 
     
     
         7 . The golf putter club head according to  claim 6  wherein polymeric material is polybutylene. 
     
     
         8 . The golf putter club head according to  claim 6  wherein said polymeric material has a 45% rebound at 84 shore A hardness. 
     
     
         9 . The golf putter club head according to  claim 6  wherein said polymeric material has a 85% rebound at 95 shore A hardness. 
     
     
         10 . The golf putter club head according to  claim 1  wherein said radial impact surface insert has an upper thickness greater than a lower thickness. 
     
     
         11 . The golf putter club head according to  claim 10  wherein said radial impact surface insert upper thickness is about 0.150 inches and said lower thickness is about 0.124, with a center of radius of about 0.875 inches from a side of the club head. 
     
     
         12 . The golf putter club head according to  claim 1  wherein said radial impact surface insert includes a plurality of grooves spaced apart about 0.031 inches having a depth of about 0.015 inches deep. 
     
     
         13 . The golf putter club head according to  claim 1  wherein said radial impact surface insert includes ten parallel disposed grooves along a length of the insert. 
     
     
         14 . The golf putter club head according to  claim 1  wherein said radial impact surface insert is shaped to allow unidirectional placement within said recessed area.
