Golf Club Head Having Center of Gravity Offset

Abstract

The present invention is directed to golf club apparatus and processes. A golf club with a center of gravity offset comprises a shaft presenting a central axis and a club head having a face and a hosel. The club head defines a first axis generally parallel to the face and collinear with the hosel. The shaft is joined to the club head at the hosel, with the shaft and hosel defining a second axis. The club head has a center of gravity configured proximate the intersection of the first axis and the second axis.

What is claimed is: 
     
         1 . A golf club with a center of gravity offset, comprising:
 a shaft presenting a central axis;   a club head having a face and a hosel, said club head defining a first axis generally parallel to said face and collinear with said hosel;   said shaft joined to said club head at said hosel, said shaft and hosel defining a second axis;   said club head having a center of gravity configured proximate the intersection of said first axis and said second axis.   
     
     
         2 . The golf club of  claim 1  wherein the static loft of the club head is substantially equal to the dynamic loft. 
     
     
         3 . The golf club of  claim 1  wherein weight is positioned lower and forward in the face of the club head. 
     
     
         4 . The golf club of  claim 1  wherein the shaft flex is optimized by matching the frequency of the golf club to the club head speed of a golfer. 
     
     
         5 . The golf club of  claim 1  wherein is the center of gravity of the club head is offset by moving masses. 
     
     
         6 . The golf club of  claim 1  wherein is the center of gravity of the club head is offset by a configured hosel position. 
     
     
         7 . A process for golf club head center of gravity offset, comprising the steps of:
 receiving golf club parameters;   determining the current center of gravity from said golf club parameters;   defining a first axis generally parallel to the face of said golf club and collinear with the hosel of said golf club;   defining a second axis defined by the shaft of said golf club to said club head at said hosel;   determining the optimum center of gravity, said optimum center of gravity defined as proximate the intersection of said first axis and said second axis.   
     
     
         8 . The process of  claim 7  further comprising the step of applying the center of gravity offset to said golf club. 
     
     
         9 . The process of  claim 8  wherein said center of gravity adjustment is accomplished by shifting more weight towards the face of the club head. 
     
     
         10 . The process of  claim 8  wherein said center of gravity adjustment is accomplished by offsetting the shaft attachment further towards the back of the club head. 
     
     
         11 . The process of  claim 8  wherein said center of gravity adjustment is accomplished by a combination of shifting more weight towards the face of the club head and offsetting the shaft attachment further towards the back of the club head. 
     
     
         12 . The process of  claim 12  further comprising optimizing the shaft flex by matching the frequency of the golf club to the club head speed of a golfer. 
     
     
         13 . A golf club accessory comprising:
 a hosel body having an upper surface and lower surface;   said lower surface having a tip for affixing to a club head;   said upper surface having a plurality of spaced apart hosels dimensioned for receipt of a shaft, whereby a user can selectively offset the center of gravity of the club head proximate the intersection of a first axis and a second axis, said club head defines said first axis generally parallel to the club face and is collinear with said hosel and said shaft and hosel defining said second axis.
