Golf putter construction

Abstract

A golf putter ( 10 ) includes a hollow tapering shaft ( 16 ), the small end connected to a handgrip ( 14 ) and the large end connected with the clubhead ( 12 ). In a second embodiment of the shaft, the shaft ( 16 ) is filled with a graphite core ( 40 ) and in a third embodiment the shaft tube includes a further tube ( 44 ).

What is claimed is:  
     
         1 . A golf putter shaft for unitarily interconnecting a handgrip to a clubhead, comprising: 
 a hollow tube of circular cross-section continuously varying from a minimum diameter at a first end to a maximum diameter at a second end;    a reduction coupling for engaging the tube first end with a handgrip; and    a connector for integrally relating the tube second end to a clubhead.    
     
     
         2 . A golf putter shaft as in  claim 1 , in which the tube minimum diameter is about ⅜ inches and the tube maximum diameter is in the range of about ⅝ to ¾ inches.  
     
     
         3 . A golf putter shaft as in  claim 1 , in which the hollow tube is substantially filled with graphite to form a solid graphite core.  
     
     
         4 . A golf putter shaft as in  claim 1 , in which the hollow tube is constructed of steel.  
     
     
         5 . A golf putter shaft as in  claim 1 , in which the hollow tube includes a further hollow tube therewithin for strength enhancement.
