Golf club having removable weight

Abstract

A golf club head includes a club head body and a weight member that is secured to the body. The weight member is constructed to utilize lateral forces to couple to the head body to minimize the structure required to retain the weight member, and the weight member is preferably constructed so that it has a low profile.

What is claimed is: 
     
         1 . A golf club head including a weight member, comprising:
 a club head body comprising a plurality of body members that combine to define a hollow body, wherein the body members include a face defining a ball-striking surface, a sole, a crown, and a skirt, wherein the sole extends aftward from a lower wedge of the face, wherein the crown extends aftward from an upper edge of the face, and wherein the skirt extends between the sole and the crown around a perimeter of the body;   a track type weight mount disposed on at least one of the body members, wherein the weight mount defines a perimeter wall of the track running lengthwise along the track type weight mount, and a weight member that includes a weight body defining a side wall and at least two spring features disposed on perpendicular portions of the side wall, wherein each spring feature is defined by an elongate aperture extending through a thickness of the weight body that intersects the side wall and the aperture is parallel to a portion of the side wall,   wherein the weight mount is sized so that the spring feature abut the perimeter wall of the track type weight mount, and wherein the spring features are at least partially flexed laterally by the abutment of the spring feature with the perimeter wall when the weight member is disposed in the weight mount.   
     
     
         2 . The golf club head of  claim 1 , wherein the spring feature of the weight member is adapted to continuously abut the perimeter wall of the track type weight mount at an infinite number of locations along the track type weight mount. 
     
     
         3 . The golf club head of  claim 2 , wherein a portion of the weight member at the spring feature has a dimension D 2  in a free state from an outer surface of the spring feature to an outer surface on an opposite side of the weight member, wherein the weight mount has a dimension across a portion of the weight mount that abuts the spring feature has a dimension D LOCK , and wherein D LOCK  is less than D 2 . 
     
     
         4 . The golf club head of  claim 2 , wherein translation of the weight member in the weight mount increases a lateral force between the spring feature and the perimeter wall. 
     
     
         5 . The golf club head of  claim 2 , wherein the weight mount includes a perimeter wall that defines an undercut. 
     
     
         6 . The golf club head of  claim 5 , wherein the perimeter wall includes a shoulder overhang, wherein a lower surface of the shoulder overhang is spaced from the bottom wall of the weight mount by a distance that is greater than the thickness of the weight member by about 0.01 inch to about 0.05 inch. 
     
     
         7 . The golf club head of  claim 6 , wherein the shoulder overhang is a bridge member that extends across a portion of the weight mount. 
     
     
         8 . The golf club head of  claim 1 , wherein the weight member further comprises a flexible locking arm on a surface of the weight body perpendicular to the side wall, wherein the spring features and the flexible locking arm are oriented to prevent relative movement between the weight member and the weight mount in three orthogonal axes. 
     
     
         9 . The golf club head of  claim 1 , wherein a height of each of the spring features is different than the overall thickness of the weight member. 
     
     
         10 . The golf club head of  claim 1 , wherein the weight member includes at least three spring features. 
     
     
         11 . A golf club head including a weight member, comprising:
 a club head body comprising a plurality of body members that combine to define a hollow body, wherein the body members include a face defining a ball-striking surface, a sole, a crown, and a skirt, wherein the sole extends aftward from a lower wedge of the face, wherein the crown extends aftward from an upper edge of the face, and wherein the skirt extends between the sole and the crown around a perimeter of the body;   a track type weight mount disposed on at least one of the body members, wherein the weight mount defines a perimeter wall of the track running lengthwise along the track type weight mount, and   a weight member that includes a weight body defining a side wall and at least two spring features disposed on perpendicular portions of the side wall, wherein each spring feature is defined by an elongate aperture extending through a thickness of the weight body that intersects the side wall and the aperture is parallel to a portion of the side wall,   wherein the weight mount is sized so that the spring feature abut the perimeter wall of the track type weight mount, and wherein the spring features are at least partially flexed laterally by the abutment of the spring feature with the perimeter wall when the weight member is disposed in the weight mount in an engaged position, and   wherein the weight mount is unflexed when it does not come into contact with the perimeter wall when the weight member is disposed in the weight mount in a disengaged position.   
     
     
         12 . The golf club head of  claim 11 , wherein the spring feature of the weight member is adapted to continuously abut the perimeter wall of the track type weight mount at an infinite number of locations along the track type weight mount. 
     
     
         13 . The golf club head of  claim 12 , wherein at least one weight member further comprises a flexible locking arm on a surface of the weight body perpendicular to the side wall, wherein the spring features and the flexible locking arm are oriented to prevent relative movement between the weight member and the weight mount in three orthogonal axes. 
     
     
         14 . The golf club head of  claim 12 , wherein a portion of the weight member at the spring feature has a dimension D 2  in a free state from an outer surface of the spring feature to an outer surface on an opposite side of the weight member, wherein the weight mount has a dimension across a portion of the weight mount that abuts the spring feature has a dimension D LOCK , and wherein D LOCK  is less than D 2 . 
     
     
         15 . The golf club head of  claim 14 , wherein the outer surfaces of the spring features are curved. 
     
     
         16 . The golf club head of  claim 11 , wherein the weight member includes at least three spring features. 
     
     
         17 . The golf club head of  claim 16 , wherein the weight mount includes a bridge member that extends across the weight mount and forms an undercut portion of the weight mount, and wherein at least one of the spring features forms a flexible locking arm that includes a locking tooth, wherein the locking tooth includes a tapered surface, wherein the tapered surface abuts and slides past a tapered surface on the bridge member when the weight member is installed in the weight mount. 
     
     
         18 . The golf club head of  claim 17 , wherein the locking tooth includes a ledge adjacent the tapered surface.
