Abstract

A metalwood type golf clubhead including a clubhead body having a toe, heel, upper crown surface, bottom sole surface, side surfaces, rear surface and ball-striking clubface having at least one raised, elongated, aerodynamically shaped reinforcing and stabilizing member extending outwardly from the clubhead body and having at least one frontal ball-striking surface coincident with the ball-striking clubface. The structure provides improved weight distribution for better balance, additional strength and stability to clubhead and provides more effective aerodynamic surfaces to increase clubhead speed.

Claims

1. A metalwood type golf club head including a club head body with a toe, heel, upper crown surface, bottom sole surface, side wall surfaces, rear wall surface and ball striking club face, wherein the improvement comprises:

means on said side wall surfaces expanding outer perimeter weighting and providing improved low profile aerodynamics to said club head;

said means including a raised, elongated, aerodynamically shaped reinforcing and stabilizing member extending outwardly from said side wall surfaces, said member having at least one frontal ball striking surface being coincident with said ball striking club face; and

, further including an expanded section extending outwardly beyond said club head body in a direction between said upper crown surface and said bottom sole surface;

said expanded section having a frontal surface coincident with said ball striking club face.

2. The golf club head of claim 1 being further defined by said reinforcing and stabilizing member extending outwardly around the entire side wall surfaces and said rear surface of said club head;

said reinforcing and stabilizing member being located between said heel and said toe;

said reinforcing and stabilizing member having a first frontal ball striking surface located at said toe and being coincident with said ball striking club face and a second frontal ball striking surface located at said heel and being coincident with said bail striking club face.

3. The golf club head of claim 1 wherein said expanded section is located below said ball striking club face extending outwardly from said bottom sole surface, said frontal surface of said frontal surface coincident with said ball striking club face of said expanded section further expanding the ball striking club face in a direction toward said bottom sole surface.

4. The golf club head of claim 1 wherein said aerodynamically shaped reinforcing and stabilizing member and said expanded section have parabolic shaped outer surfaces.

5. The golf club head of claim 1 wherein said aerodynamically shaped reinforcing and stabilizing member and said expanded section are formed with a variable thickness.

6. The golf club head of claim 5 wherein said aerodynamically shaped reinforcing and stabilizing member and said expanded section are formed with a thickness greater than the thickness of said club head body.

7. The golf club head of claim 6 wherein said thickness of said aerodynamically shaped reinforcing and stabilizing member is within the range of 0.055 to 0.100-inch.

8. A metalwood type golf club head including a club head body with a toe, heel, upper crown surface, bottom sole surface, side wall surfaces, rear wall surface and ball striking club face, wherein the improvement comprises:

means on said side wall surfaces expanding outer perimeter weighting and providing improved low profile aerodynamics to said club head, said means including a raised, elongated, aerodynamically shaped reinforcing and striking member extending outwardly around the entire side wall surfaces and said rear surface of said club head;

said reinforcing and stabilizing member being located between said heel and said toe;

said reinforcing and stabilizing member having a first frontal ball striking surface at said toe being coincident with said ball striking club face and a second frontal ball striking surface at said heel being coincident with said ball striking club face; and

, including an expanded section extending outwardly from said club head body in a direction between said upper crown surface and said bottom sole surface;

said expanded section having a further frontal surface coincident with said ball striking club face.

9. The golf club head of claim 8 wherein said expanded section is located below said ball striking club face extending outwardly from said bottom sole surface, said frontal surface being coincident with said ball striking club face of said expanded section further expanding the ball striking club face in a direction beyond said bottom sole surface.
