Golf club head with dimpled surfaces

Abstract

A new method for manufacturing hollow golf club heads is presented where the metal of the upper and lower club surfaces is impressed with regular dimples in a geometric pattern. The dimpling of the metal confers additional structural strength to the club head, permitting reduction in the weight of metal in the club head per unit of strength. The club also has improved aerodynamic characteristics during the golf swing and because of the reduced amount of surface area contacting the ground, reduced friction with the ground upon contacting the ball.

1 . a golf club head with dimpled surfaces, the golf club head comprised of a hitting surface, a head top, a head bottom, and a head side,
 the head top and head bottom each possessing a surface with a plurality of dimples impressed upon it, the hitting surface and the head side otherwise smooth with no dimples.   
   
   
       2 . The golf club head of  claim 1 , where the golf club head is comprised of a metal selected from the group of aluminum, magnesium, titanium, and steel. 
   
   
       3 . The golf club head of  claim 1  where the plurality of dimples on the surface of the head top and the head bottom are arranged in a regular pattern. 
   
   
       4 . The golf club head of  claim 3  where the regular pattern is chosen to confer strength in resisting lateral force to the head top and head bottom. 
   
   
       5 . The golf club head of  claim 3  where the regular pattern is chosen to confer strength in resisting lateral force to the head top and head bottom and the regular pattern is also chosen to confer aerodynamic properties to the golf club head when the golf club is swung.
