Abstract

Claims (61)

1 . A golf club head comprising:

a striking face provided near a forward portion of said golf club head;

a body portion connected to an aft portion of said striking face further comprising a crown, a sole, and a skirt,

wherein said crown further comprises;

a constant thickness portion located near said striking face, and

a transition portion located aft of said constant thickness portion,

wherein said striking face further comprises;

a perimeter portion made out of a first material having a first density around a border of said striking face, and

a central portion near a center of said striking face surrounded by said perimeter portion,

wherein said central portion comprises a backing portion,

wherein said central portion defines a pocket having a dovetail shaped undercut, and

said pocket is filled with a face insert having a dovetail shaped protrusion around its perimeter, said dovetail protrusion adapted to engage said dovetail shaped undercut,

wherein said face insert is made out of a second material having a second density,

wherein said second density is less than said first density,

wherein said dovetail shaped protrusion extends a distance (d 11 ) between about 3 mm to about 6 mm into said dovetail shaped undercut,

wherein said dovetail shaped protrusion forms an angle θ of between about 35 degrees to about 60 degrees with said striking face, and

wherein said distance (d 11 ) is generally greater than a thickness (d 3 ) of said backing portion.

2 . The golf club head of claim 1 , wherein said angle θ is between about 40 degrees to about 55 degrees.

3 . The golf club head of claim 2 , wherein said angle θ is between about 45 degrees to about 50 degrees.
