Abstract

A composite construction of a golf club head including a plurality of laminated wooden layers and a plurality of resin impregnated fiber layers provided between said wooden layers characterized in that each of said wooden layers is provided with engagement surfaces for interengaging with other wooden layers. The engagement surfaces includes a plurality of tongue-and-groove surfaces in the direction perpendicular to the direction of the stroke.

Claims

1. A golf club head comprising a body and a throat adapted for connection to a shaft, the body and the throat being of unitary construction and the body defining a strike face for the head, the body and the throat being constructed of a plurality of wooden laminations and a plurality of resin impregnated fiber layers disposed between the wood laminations and securing the wood laminations to each other, opposing surfaces of adjoining wood laminations defining a plurality of interlocking tongues-and-grooves extending generally in the direction substantially parallel to the strike face and distributed across the opposing wood lamination surfaces from an edge of the laminations proximate the strike face to another edge of the laminations.

2. A golf club head according to claim 1 wherein the interlocking tongues-and-grooves have a generally trapezoidal cross-section.

3. A composite construction of a golf club head including a plurality of laminated wooden layers and a plurality of resin impregnated fiber layers provided between said wooden layers wherein each of said wooden layers is provided with an engagement surface including means for establishing a mechanical interlocking engagement with another wooden layer.

4. A composite construction as claimed in claim 3, wherein the means of said engagement surfaces includes a plurality of spaced apart tongue-and-groove surfaces extending in the direction substantially parallel to the strike face.

5. A composite construction as claimed in claim 4, wherein said tongue-and-groove surfaces are trapezoidal in cross-section.
