Abstract

A wood type golf club head having at least a single shallow aerodynamic slot formed on the upper surface of the club head and extending from adjacent the rear edge to a point approximately midway on the upper surface and substantially from the ball striking face. Other embodiments include a plurality of slots in parallel, angular and multiple tier configurations.

Claims

1. A wood type golf club head having a hosel, a heel, a toe, an upper surface on a top portion of said club head, a rear surface and a ball striking face with a center of percussion thereon and a sole;

means for altering air flow across said upper surface, said means including;

a two-level configuration on said upper surface, said two-level configuration including a first level extending from said ball striking face rearwardly and a second level extending from said rear surface forwardly, an interface formed between said first and second levels extending uninterrupted substantially from said heel to said toe;

said first and second levels formed on said top portion of the club head;

said second level including at least one shallow aerodynamic air slot formed proximate said rear surface and extending forwardly to said interface of said upper and lower levels;

said air slot having a bottom surface forming a third level on said top surface of said golf club;

said three levels being disposed above a mid-plane between said upper surface and said sole;

said three-levels providing an aerodynamic configuration on said top surface of said club head for altering air flow across said surface.

2. The golf club head of claim 1 formed with multiple air slots.

3. The golf club head of claim 1 wherein said air slot is formed with an upward ramp adjacent said rear surface.

4. The golf club head of claim 1 wherein the air slot has a depth of less than 0.250 inches.
