Golf Putter

Abstract

Golf clubs, and more particularly to a golf putter and a club head for a putter are disclosed. In one embodiment, the club head has a body having a club face, a first extension portion at the first end of the club face extending in a direction either outwardly, or rearwardly and outwardly away from the center of the club face; and a second extension portion at the second end of the club face extending in a direction either outwardly, or rearwardly and outwardly away from the center of the club face. In this embodiment, at least one of the first and second extension portions forms an angle of greater than or equal to about 40°, 45°, or some other suitable angle, and less than or equal to about 90° from an imaginary line oriented perpendicular to the club face and passing through at least one of the outermost portion of the club face at the heel or the toe of the club face. One or both of the extensions may have a weight joined thereto, which weight comprises a material having a specific gravity that is higher than that of at least a portion of the body of the club head.

What is claimed 
     
         1 . A golf putter-type club head comprising:

         2 . The golf putter-type club head of  claim 1  wherein said body has more than one opening formed therein sized and configured for receiving a golf club shaft or a hosel and shaft arrangement, wherein only one of said openings is used to receive a golf club shaft or a hosel and shaft arrangement 
     
     
         3 . The golf putter-type club head of  claim 1  wherein said club face has a thickness, and said extensions have a length and a thickness, wherein at least one of the extensions has a thickness measured along at least a portion of its length that is less than the thickness of the club face, wherein the thickness of the club face is measured inclusive of any flange and exclusive of any central element or alignment means extending from the back portion of the club face. 
     
     
         4 . The golf putter-type club head of  claim 1  wherein said club face has a top surface, and said extensions have a length and top surface, wherein at least one of the extensions has a top surface along at least a portion of its length that is lower than the top surface of the club face when the sole of the club head is placed flat on the ground. 
     
     
         5 . The golf putter-type club head of  claim 1  wherein the leading edge of at said least one of said extensions that forms said angle from said imaginary line is defined by a rectilinear segment when said club head is viewed from address position. 
     
     
         6 . The golf putter-type club head of  claim 5  wherein the leading edge of said at least one of said extensions forms an angle with said club face. 
     
     
         7 . The golf putter-type club head of  claim 1  wherein said extensions have a top surface, wherein at least one of the weights joined to said first and second extensions has a top surface, and at least a portion of the top surface of said at least one of said weights is disposed above the top surface of the extension to which it is joined. 
     
     
         8 . The golf putter-type club head of  claim 1  wherein at least one of said weights joined to said first and second extensions is cylindrical and has two circular faces. 
     
     
         9 . The golf putter-type club head of  claim 8  wherein said at least one of said weights which is cylindrical is oriented with one of its circular faces facing upward. 
     
     
         10 . A golf putter-type club head according to  claim 1  further comprising a shaft having a tip end and a butt end, said tip end of said shaft being joined to said club head, and said butt end of said shaft having a grip thereon to form a putter. 
     
     
         11 . A golf putter-type club head comprising:
 a body having a club face, a top portion, a sole portion, a heel portion, and a toe portion, wherein said club face has a center, a first end at said heel portion, and a second end at said toe portion, said body being comprised of a material having a first specific gravity;   a first extension portion extending in a direction either outwardly in a direction in the plane of the club face oriented directionally away from the center of the club face beyond the first end, or rearwardly and outwardly away from the first end of the club face, said first extension portion having a leading edge, a proximal end in the region of the first end of said club face, and a distal end disposed away from said club face, said first extension having a weight joined thereto in the region of the distal end thereof, said weight having a second specific gravity higher than said first specific gravity; and   a second extension portion extending in a direction either outwardly in a direction in the plane of the club face oriented directionally away from the center of the club face beyond the second end, or rearwardly and outwardly away from the second end of the club face, said second extension portion having a leading edge, a proximal end in the region of the second end of said club face, and a distal end disposed away from said club face, said second extension having a weight joined thereto in the region of the distal end thereof, said. weight having a second specific gravity higher than said first specific gravity,   wherein one of the extensions is longer than the other extension.   
     
     
         12 . The golf putter of  claim 11  wherein the leading edge of said at least one of said extensions is disposed rearwardly of said club face. 
     
     
         13 . A golf putter-type club head according to  claim 11  further comprising a shaft having a tip end and a butt end, said tip end of said shaft being joined to said club head, and said butt end of said shaft having a grip thereon to form a putter.
