First Claim
Patent Images
1. A golf club head comprising:
- a body having a face, a sole portion, a crown portion and a skirt portion joining the face, sole portion and crown portion;
a hollow golf club interior within the body;
an outermost exterior surface provided opposite the hollow golf club interior;
a plurality of depressions provided on a first portion of the outermost exterior surface of the body;
wherein the plurality of depressions are formed in the outermost exterior surface and have a depth of about 0.5 mm to about 2 mm, have a width of about 6 mm to about 20 mm and have a minimum landing surface spacing of about 0.5 mm to about 7 mm between depressions on the outermost exterior surface, wherein the depressions are oriented aligned in rows perpendicular to the face.

Abstract
A golf club head where at least a first portion of an exterior surface of the golf club head includes depressions is disclosed herein. More specifically, the golf club head has a body with a striking face, a crown portion, a sole portion, and a skirt portion joining the striking face, crown portion and the sole portion and in accordance with the present invention at least a portion of the exterior surface of the body of the golf club head is further comprised of depressions to reduce the aerodynamic drag force on the golf club head. The depressions may be provided on a first portion of the golf club head on one or more of a crown portion, sole portion, skirt portion or striking face.

11. A golf club head comprising:
-
a body having a face, a sole portion, a crown portion and a skirt portion joining the face portion, sole portion and crown portion; a hollow golf club interior within the body; and an outermost exterior surface provided opposite the hollow golf club interior, wherein a first aerodynamic drag force reduction of the club head is achieved by shaping the body of the club head, and a second aerodynamic drag force reduction of the club head is achieved by providing a plurality of depressions on a first portion of the outermost exterior surface of the body wherein the plurality of depressions have a depth extending from the outermost exterior surface and a landing surface between depressions provided on the outermost exterior surface, and wherein the additional reduction in aerodynamic drag force achieved by the second aerodynamic drag force reduction is about 5 to about 25 percent, and wherein the depressions are oriented aligned in rows perpendicular to the face. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
