Golf putter

Abstract

A golf putter head having a body having a striking face, a top portion, a bottom portion, a toe portion, and a heel portion. The putter head further has at least one weight member connectable to the body at a predetermined location on the body such that the golf putter head has a first center of gravity. The at least one weight member is repositionable with respect to and connectable to the body such that repositioning the weight member and connecting the weight member to the body at the predetermined location on the body causes the golf putter head to have second center of gravity that is different both horizontally and vertically from the first center of gravity.

       12 . The golf putter head of  claim 1  wherein the weight is movable with respect to the post. 
   
   
       13 . The golf putter head of  claim 1  wherein the body is at least partially composed of a first material and the weight member is at least partially composed of a second material that has a higher density than the first material. 
   
   
       14 . The golf putter head of  claim 1  further comprising at least one alignment aid. 
   
   
       15 . The golf putter head of  claim 14  wherein the at least one of alignment aid comprises a line generally perpendicular to the striking face. 
   
   
       16 . The golf putter head of  claim 1  wherein the at least one weight member is positionable with respect to the body such that the at least one weight member contacts a ground surface when the putter head is grounded, thereby changing a lie angle of the putter head by preventing at least part of the bottom portion of the body from contacting the ground surface when the putter head is grounded. 
   
   
       17 . A golf putter head comprising:
 a body having a striking face, a top portion, a bottom portion, a toe portion, and a heel portion; and   at least one weight member connectable to the body at a predetermined location on the body such that the golf putter head has a first center of gravity;   wherein the at least one weight member is repositionable with respect to and connectable to the body such that repositioning the weight member and connecting the weight member to the body at the predetermined location on the body causes the golf putter head to have second center of gravity that is different both horizontally and vertically from the first center of gravity.   
   
   
       18 . The golf putter head of  claim 17  comprising two weight members and two predetermined locations on the body. 
   
   
       19 . The golf putter head of  claim 18  wherein one of the predetermined locations on the body is on the heel portion and is closer to the heel of the body than to the center of the body and the other of the predetermined locations on the body is on the toe portion and is closer to the toe of the body than to the center of the body. 
   
   
       20 . The golf putter head of  claim 18  wherein each of the two weight members is positionable such that the two weight members in combination have a first position with respect to the body, thereby causing the putter head to have the first center of gravity location, and wherein each of the two weight members is positionable such that the two weight members in combination have a second position with respect to the body, thereby causing the putter head to have a second center of gravity location that is different both horizontally and vertically from the first center of gravity location. 
   
   
       21 . The golf putter head of  claim 18  wherein the golf putter head has a first sweet spot when the two weights in combination have a first position with respect to the body and a second sweet spot when the two weights in combination have a second position with respect to the body, and wherein the second sweet spot is different in dimension horizontally from the first sweet spot.

       23 . The golf putter head of  claim 17  wherein the at least one weight member is positionable with respect to the body the golf putter head such that the bottom portion of the body is not in contact with the ground when the golf putter head is grounded. 
   
   
       24 . The golf putter head of  claim 17  wherein the at least one weight member is repositionable with respect to the body such that the at least one weight member contacts a ground surface when the putter head is grounded, thereby changing a lie angle of the putter head by preventing at least part of the bottom portion of the body from contacting the ground surface when the putter head is grounded. 
   
   
       25 . A golf putter head comprising:
 a body having a striking face, a top portion, a bottom portion, a toe portion, and a heel portion; and   at least two weight members connectable to the body at predetermined locations on the body such that the golf putter head has a first sweet spot and a first center of gravity;   wherein the at least two weight members are repositionable with respect to and connectable to the body at the predetermined locations on the body such that repositioning the weight members and connecting the weight members to the body at the predetermined locations on the body causes the golf putter head to have a second center of gravity that is different vertically from the first center of gravity and further causes the golf putter head to have a second sweet spot that is different in dimension horizontally from the first sweet spot.   
   
   
       26 . A golf putter head comprising:
