Golf putter with range of feel characteristics

Abstract

A golf putter head includes a back body and a face body having a golf ball contact surface. The face body includes an entirety of the contact surface, with the back body and the face body having surfaces without contact across a gap defined by the surfaces. The golf putter head further includes a vibration dampening intermediate body filling the gap to isolate the face body from the back body by completely separating the back body and the face body from one another. The intermediate body has a durometer selectable during assembly of any number within a range of 40 to 90 Shore-A. A coefficient of restitution of the golf ball contact surface of the golf putter head has a direct relationship with the durometer of the intermediate body such that golf putter heads with varying coefficients of restitution may be fabricated by varying the durometer of the intermediate body.

What is claimed is: 
     
         1 . A golf putter head comprising:
 a back body adapted to be secured to a golf club shaft;   a face body including a golf ball contact surface, the face body including an entirety of the contact surface, the back body and the face body having surfaces without contact across a gap defined by the surfaces; and   a vibration dampening intermediate body filling the gap to isolate the face body from the back body by completely separating the back body and the face body from one another, the intermediate body being affixed to the back body and the face body, the intermediate body having a durometer selectable during assembly of any number within a range of 40 to 90 Shore-A,   a coefficient of restitution of the golf ball contact surface of the golf putter head being in a direct relationship with the durometer of the intermediate body such that golf putter heads with varying coefficients of restitution may be fabricated by varying the durometer of the intermediate body.   
     
     
         2 . The golf putter head of  claim 1 , wherein the coefficient of restitution of the putter head measured using a static drop method is in a range from 0.75 to 0.95. 
     
     
         3 . The golf putter head of  claim 1 , wherein the coefficient of restitution of the putter head measured using a static drop method is less than 0.75. 
     
     
         4 . The golf putter head of  claim 1 , wherein the intermediate body does not extend to the face of the golf putter head. 
     
     
         5 . The golf putter head of  claim 1 , wherein the outermost perimeter of the face body defines an outermost perimeter of the golf putter head. 
     
     
         6 . The golf putter head of  claim 1 , wherein the front surface of the face body comprises only a portion of the front surface of the golf putter head. 
     
     
         7 . The golf putter head of  claim 1 , wherein the intermediate body has a durometer of 50 to 60 Shore-A. 
     
     
         8 . The golf putter head of  claim 1 , wherein the intermediate body has a durometer of 70 Shore-A. 
     
     
         9 . The golf putter head of  claim 1 , wherein the intermediate body has a durometer of 90 Shore-A. 
     
     
         10 . The golf putter head of  claim 1 , wherein the intermediate body can be selected from one of several durometers. 
     
     
         11 . The golf putter head of  claim 1 , wherein the intermediate body options include durometers of 50 to 60, 70 and 90 Shore-A. 
     
     
         12 . The golf putter head of  claim 1 , wherein the intermediate body includes a first surface and a second, opposing surface. 
     
     
         13 . The golf putter head of  claim 12 , wherein at least one of the first surface and the second surface includes a series of ridges, grooves, or indentations formed on the surface.
