Abstract

A metal wood type golf club head having a c-shaped aerodynamic configuration formed in the bottom surface adjacent a rear surface and having an open end extending forwardly toward the ball striking face in combination with a skid surface.

Claims

1. An aerodynamic golf club head including a club head body having a heel, toe, rear surface, ball striking face, upper surface and bottom surface, wherein the improvement comprises:

an aerodynamic configuration on said bottom surface adjacent said rear surface in the form of a c-shaped slot having an open end facing forwardly toward said ball striking face;

said aerodynamic configuration further including a skid surface formed on and raised from said bottom surface;

said skid surface having a wall separating said skid surface from said bottom surface.

2. The aerodynamic golf club head of claim 1 further including a venturi opening in fluid communication with and extending rearwardly from said c-shaped aerodynamic slot toward said rear surface.

3. The aerodynamic golf club head of claim 1 wherein said slot is further defined by being offset from said heel of said club head.

6. The aerodynamic golf club head of claim 3 wherein said slot is offset toward said toe.

7. The aerodynamic golf club of claim 1 wherein said slot is further defined by being offset from said toe of said club head.

4. An aerodynamic golf club head including a club head body having a heel, toe, rear surface, ball striking face, upper surface and bottom surface, wherein the improvement comprises:

an aerodynamic configuration on said bottom surface adjacent said rear surface in the form of a c-shaped slot having an open end facing forwardly toward said ball striking face;

said slot being offset from a center of said bottom surface centerline passing through a longitudinal in a heel-to-toe direction.

5. The aerodynamic golf club head of claim 4 wherein said slot is offset toward said heel.

8. An aerodynamic golf club head including a club head body having a heel, toe, rear surface, ball striking face, upper surface and bottom surface, wherein the improvement comprises:

an aerodynamic configuration on said bottom surface adjacent said rear surface in the form of a c-shaped slot having an open end facing forwardly toward said ball striking face;

said aerodynamic configuration further including a venturi opening in fluid communication with and extending rearwardly from said c-shaped aerodynamic slot toward said rear surface.
