Golf Club Head Having Center of Gravity Offset

Abstract

A wood type golf club includes a face and a hosel with a center of gravity offset. A shaft presents a central axis, and is joined to the wood type club head at the hosel, the shaft presenting an axis projected through the hosel and through the club head. The shaft and hosel present a plane relative to and generally parallel to the face of the club head. The wood type club head has a center of gravity configured within the plane.

What is claimed is: 
     
         1 . A wood type golf club with a center of gravity offset, comprising:
 a shaft presenting a central axis;   a wood type club head having a face and a hosel;   said shaft joined to said wood type club head at said hosel, said shaft presenting an axis projected through said hosel and through said club head;   said shaft and hosel presenting a plane relative to and generally parallel to said face of said club head;   said wood type club head having a center of gravity configured within said plane and outside said projected axis by said shaft to hosel joint.   
     
     
         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 parameters for said golf club head, including dimensions and mass;   determining the current center of gravity from said golf club head parameters;   projecting an axis presented by said shaft projected through said hosel and through said club head;   projecting a plane presented said shaft and hosel relative to and generally parallel to said face of said club head;   determining the optimum center of gravity, said optimum center of gravity defined as within said plane and outside said projected axis by said shaft to hosel joint.   
     
     
         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 in a series of successively spaced apart planes generally parallel to the club face.
