Golf putter head

Abstract

The present invention relates to a golf putter head, that is, to a golf putter head that strikes a golf ball using the front surface of the head when putting, the golf putter head comprising: a lower guide formed so as to extend from a bottom of a rear surface of the head; an upper guide formed so as to extend from the rear surface of the head at a predetermined distance above the lower guide in order to define a space portion; and a pivoting tail portion, one end of which is inserted into the space portion and pivotably fixed in the space portion by means of a fixing member, wherein a structure for controlling the degree of pivoting is formed in order to control the pivoting angle of the pivoting tail portion, the weight balance of the head is variable according to the pivoting angle of the pivoting tail portion, and the pivoting tail portion is formed in the shape of a bar having a rounded edge at the end thereof that is fixed by the fixing member.

1 . A golf putter head that strikes a golf ball using the front surface of a head  210  when putting, the golf putter head comprising: a lower guide  220  formed so as to extend from a bottom of a rear surface of the head  210 ; an upper guide  240  formed so as to extend from the rear surface of the head  210  at a predetermined distance above the lower guide  220  in order to define a space portion  230 ; and a pivoting tail portion  260 , one end of which is inserted into the space portion  230  and pivotably fixed in the space portion  230  by means of a fixing member  250 , wherein a structure for controlling the degree of pivoting is formed in order to control the pivoting angle of the pivoting tail portion  260 , the weight balance of the head  210  is variable according to the pivoting angle of the pivoting tail portion  260 , and the pivoting tail portion  260  is formed in the shape of a bar having a rounded edge at the end thereof that is fixed by the fixing member  250 . 
     
     
         2 . The golf putter head according to  claim 1 , wherein the structure for controlling the degree of pivoting comprises a recess  420  which is formed at an identical interval in a circumference of the pivoting tail portion  260  which is rounded, a groove  430  which is formed in a center of an internal lateral surface of the space portion  230 , an elastic member  280  which is inserted into the groove  430  and a ball  270  which is fitted to the groove  430  and closely adhered to the recess  420  by the elastic member  280 , wherein the ball  270  acts as a stopper when the pivoting tail portion  260  pivots. 
     
     
         3 . The golf putter head according to  claim 2 , wherein three recesses  420  are formed so that the pivoting tail portion  260  is pivotably arranged in three directions comprising horizontal, vertical and diagonal directions with respect to the rear surface of the head  210 . 
     
     
         4 . The golf putter head according to  claim 1 , wherein a weight-adding portion  410  is formed to give additional load to the other end of the pivoting tail portion  260 .
