Golf club head with variable center of gravity

Abstract

A golf club head with a variable center of gravity is disclosed herein. More specifically, the present invention discloses a wedge type golf club head wherein the center of gravity of the golf club head is adjustable along an x-axis in a heel to toe direction utilizing weights that are placed substantially near a sole portion of the golf club head. The resulting golf club head may generally have a more toe biased center of gravity location, especially when compared to a traditional golf club head.

1 . A wedge type golf club head comprising:
 a striking face portion located at a frontal portion of said wedge type golf club head;   a backing portion located behind said striking face portion; and   a sole muscle portion located at a bottom of said wedge type golf club head between said striking face portion and said backing portion, wherein said sole muscle portion further comprises only one of a cavity having an opening and one or more weights shaped to at least partially fit in said cavity, wherein said wedge type golf club head has a center of gravity greater than about 28 mm from an intersection point between a hosel bore axis and a ground plane along an x-axis.   
     
     
         2 . The wedge type golf club head of  claim 1 , wherein said wedge type golf club head has a center of gravity greater than about 30 mm from an intersection point between a hosel bore axis and a ground plane along an x-axis. 
     
     
         3 . The wedge type golf club head of  claim 2 , wherein said wedge type golf club head has a center of gravity greater than about 33 mm from an intersection point between a hosel bore axis and a ground plane along an x-axis. 
     
     
         4 . The wedge type golf club head of  claim 1 , wherein said opening of said cavity is opened towards a bottom sole portion of said sole muscle portion. 
     
     
         5 . The wedge type golf club head of  claim 4 , further comprising a cover, adapted to conceal said cavity. 
     
     
         6 . The wedge type golf club head of  claim 5 , wherein a perimeter of said cover is smaller than a perimeter of said cavity. 
     
     
         7 . The wedge type golf club head of  claim 1 , wherein said opening of said cavity is opened towards a rear portion of said sole muscle portion. 
     
     
         8 . The wedge type golf club head of  claim 1 , further comprising a weight pocket located at an upper toe portion of said backing portion of said wedge type golf club head. 
     
     
         9 . The wedge type golf club head of  claim 8 , further comprising a weight pad, located congruently within said weight pocket. 
     
     
         10 . A golf club head comprising:
 a striking face portion located at a frontal portion of said golf club head;   a backing portion located behind said striking face portion; and   a sole muscle portion located at a bottom of said golf club head between said striking face portion and said backing portion, wherein said sole muscle portion further comprises only one of a cavity having an opening and one or more weights shaped to at least partially fit in said cavity, wherein said opening of said cavity is opened towards a bottom sole portion of said sole muscle portion, and wherein said golf club head has a center of gravity greater than about 28 mm from an intersection point between a hosel bore axis and a ground plane along an x-axis.   
     
     
         11 . (canceled) 
     
     
         12 . The golf club head of  claim 10 , wherein said one or more weights have a density greater than about 17 g/cm 3 . 
     
     
         13 . The golf club head of  claim 12 , wherein said one or more weights are biased towards a toe portion of said cavity. 
     
     
         14 . The golf club head of  claim 12 , wherein said one or more weights are biased towards a heel portion of said cavity. 
     
     
         15 . The golf club head of  claim 14 , further comprising a weight pocket located at an upper toe portion of said backing portion of said golf club head. 
     
     
         16 . The golf club head of  claim 15 , further comprising a weight pad, located congruently within said weight pocket. 
     
     
         17 . A golf club head comprising:
 a striking face portion located at a frontal portion of said golf club head;   a backing portion located behind said striking face portion;   a sole muscle portion located at a bottom of said golf club head between said striking face portion and said backing portion, only one of a weight pocket located at an upper toe portion of said backing portion of said golf club head, and   a weight pad, located congruently within said weight pocket,   wherein said wedge type golf club head has a center of gravity greater than about 28 mm from an intersection point between a hosel bore axis and a ground plane along an x-axis.
