Golf club that can be tailored to user using various kinds of blocks

Abstract

The present invention provides a golf club that can be tailored to the user using various kinds of blocks. A block ( 13 ) is coupled to the golf club, the block ( 13 ) having a recessed groove ( 14 ) formed on the upper surface thereof to be recessed inward and having a fitting groove ( 12 ) formed on the lower portion thereof so as to protrude downward. Even between different blocks ( 13 ), the recessed grooves ( 14 ) and the fitting grooves ( 12 ) can be coupled to each other. When two or more blocks ( 13 ) are coupled, the recessed grooves ( 14 ) and the fitting grooves ( 12 ) of the two blocks ( 13 ) can be fitted, and screws can then be fitted from the recessed grooves, thereby coupling the two blocks ( 13 ).

1 . A golf club that can be tailored to a user using various kinds of blocks, the golf club being configured such that a block ( 13 ) is coupled to the golf club, the block ( 13 ) including a recessed groove ( 14 ) provided on an upper surface thereof by being recessed inward and an insertion protrusion ( 12 ) provided on a lower surface thereof by protruding downward, wherein between one block ( 13 ) and another block ( 13 ), the recessed groove ( 14 ) and the insertion protrusion ( 12 ) are couplable to each other, and when at least two blocks ( 13 ) are coupled to each other, the recessed groove ( 14 ) of a block ( 13 ) and the insertion protrusion ( 12 ) of an adjacent block ( 13 ) are engaged with each other, and then a screw is fitted into the blocks from the recessed groove to couple the at least two blocks ( 13 ). 
     
     
         2 . The golf club of  claim 1 , wherein the screw includes: a threaded region ( 23 ) with threads; and a flat region ( 24 ) without threads, and
 the block ( 13 ) is configured such that internal threads ( 23 ) are formed at an internal part thereof into which the screw is inserted, except locations close to the recessed groove ( 14 ) and the insertion protrusion ( 12 ), whereby the threaded region ( 23 ) of the screw is engaged with the internal threads ( 23 ).   
     
     
         3 . The golf club of  claim 2 , wherein the screw includes at least two threaded regions ( 23 ). 
     
     
         4 . The golf club of  claim 2 , wherein the screw is formed with the threaded region ( 23 ) at an end thereof, and
 of the blocks ( 13 ) coupled to each other, a lowermost block ( 13 ) is provided with the internal threads partially formed at an internal part thereof.
