Abstract

A wood type golf club head having a raised, aerodynamic air foil member extending upwardly from the top surface and positioned with its longitudinal axis extending rearwardly from the ball striking face toward the rear edge of the club head. The improved air foil member redirects and creates a favorable air flow pattern as the golf club head is swung, which spills over to the rear of the club head and decreases drag, thereby enabling a golfer to hit a golf ball further and straighter for a given force during the execution of a golf swing.

Claims

1. A wood type golf club head having a heel, a toe, a top surface, a bottom, a ball striking face and a rear surface, the improvement comprising:

means for reducing the aerodynamic drag on the club head and providing increased club head speed for a given force when swinging the club;

said means including at least one elongated, rectangularly shaped member having a height of at least 1/4 inch extending above the top surface and a width of at least 1/2 inch in the heel to toe direction, said member having a leading edge extending upwardly adjacent to and slightly behind said ball striking face and a trailing edge terminating adjacent said rear surface, said member including a planar upper surface and sides extending between said planar upper surface and said top surface of said golf club head, said sides defining the height of the member; and

,

said member forming an air foil for creating air flow turbulence as the golf club is swung.

2. The wood type golf club head of claim 1, further including a pair of longitudinal air channels positioned adjacent said shaped member and extending between said ball striking face and said rear surface, said channels in combination with said shaped member further increasing the aerodynamic effects on the air flow when said golf club head is swung.

3. The wood type golf club head of claim 2 wherein said channels are slots having edges parallel to the sides of said shaped member.

4. The wood type golf club head of claim 2 wherein the channels include edges which flare outwardly between said ball striking face and said rear surface.

5. The wood type golf club head of claim 4 wherein said edges of said channels extend to the peripheral edges of the club head adjacent the toe and heel of the club head approximately midway between the ball striking face and the rear surface.

6. The wood type golf club head of claim 1 wherein said shaped member includes a downward slope approximately midway along the longitudinal axis of the shaped member, and an upward ramp located adjacent a rear section of the shaped member at the rear surface of the club head.

7. The golf club head claim 1 wherein said shaped member extends partway between the ball striking face and a rear surface of the club head, and includes a ramp having an upward-sloping surface sloped in the direction toward the rear surface of the club head.

8. The golf club head of claim 1 wherein said shaped member is trapezoidal in shape, having sides which flare outwardly toward the rear surface of the club head.

9. The golf club head of claim 1 wherein said shaped member includes a forward section with parallel sides and a rearward section having sides which flare outwardly toward the rear surface.
