Golf club

Abstract

The invention relates to a golf club ( 1 ) comprising a shaft ( 3 ) provided with a handle portion ( 2 ) and a club blade ( 5 ) projecting from the lower portion ( 4 ) of said shaft ( 3 ), the hitting surface ( 6 ) of said blade is provided with a plurality of scores or grooves ( 7 ). Those grooves ( 7 ) are arranged at a predetermined mutual distance and do extend in a diverging or parallel pattern or area over at least the hitting surface ( 6 ) of the club blade ( 5 ).

1 . A golf club comprising a shaft ( 3 ) provided with a handle portion ( 2 ) and a club blade ( 5 ) projecting from its lower portion ( 4 ) and, on the hitting surface ( 6 ) of the blade ( 5 ), a plurality of scores or grooves ( 7 ), which are located at a predetermined distance from each other and over at least the hitting surface ( 6 ) of the club blade ( 5 ) are arranged in a diverging or parallel pattern, characterized in that said grooves ( 7 ) on the hitting surface ( 6 ) of the club blade ( 5 ) are at different mutual distances, as counted from the blade bottom to its top or from its toe ( 8 ) to its heel ( 9 ), or in the opposite direction, and do at the same time diverge from the toe ( 8 ) towards the heel ( 9 ) or from the bottom towards the top.  
     
     
         2 . A golf club as claimed in  claim 1 , characterized in that said grooves ( 7 ) are arranged at a smaller mutual distance at the bottom than at the top of the club blade ( 5 ).  
     
     
         3 . A golf club as claimed in  claim 1 , characterized in that the distances between said grooves ( 7 ) are selected so as to match the wanted backspin effect.  
     
     
         4 . A golf club as claimed in  claim 1 , characterized in that the distances between said grooves ( 7 ) vary in relation to the distance from the centre of a club blade ( 5 ) towards the grooves ( 7 ).  
     
     
         5 . A golf club as claimed in  claim 1 , characterized in that said grooves ( 7 ) are diverging and also arranged over the hitting surface ( 6 ) of the club blade ( 5 ) at varying mutual distances.  
     
     
         6 . A golf club as claimed in  claim 1 , characterized in that the extension of each groove ( 7 ) over the hitting surface ( 6 ) of the club blade ( 5 ) is displaced relatively an adjacent groove ( 7 ).  
     
     
         7 . A golf club as claimed in  claim 1 , characterized in that said grooves ( 7 ) extend continously and/or discontinously over the hitting surface ( 6 ) of the club blade ( 5 ).
