Golf club head structure

Claim 1

In combination with a golf club shaft having a first end portion, a golf club head having a top surface, a flat bottom surface, first and second side surfaces, a flat leading ball striking surface and a trailing surface, and a tubular member that extends upwardly from said golf club head and has said first end portion of said shaft situated within the interior thereof and bonded thereto, said golf club head being characterized by a plurality of spaced substantially parallel grooves defined therein that extend inwardly from each of said top, bottom and second side surfaces and said grooves on said top and bottom surfaces extending from said leading ball striking surface to said trailing surface, with said plurality of grooves as said club is swung having air flowing rearwardly therethrough and acting as directional vanes to maintain said club in a desired arcuate path to minimize twisting of the club and forcing said ball striking surface to remain normal to said arcuate path during impact with a golf ball, and said grooves in said bottom surface lessening the area of the latter that may contact the ground surface just prior to impact with a golf ball, and this lessened bottom surface lessening the frictional drag that results from contact between said bottom surface and ground surface wherein increased kinetic energy is transferred from said golf club heat to said golf ball to drive the latter, with the major portion of said club formed from wood and said ball striking surface defined by a non-metallic plate secured to the leading surface of said wood portion, and said grooves defined in said top and bottom extending through the top and bottom edge portions of said plate.
