METAL WOOD CLUB WITH IMPROVED MOMENT OF INERTIA
First Claim
1. A golf club head comprising a face, crown, skirt, hosel and sole,wherein the sole comprises at least a first weight member, a second weight member, and a non-weighted section;
- wherein the first weight member is located toward and substantially parallel to the face edge of the sole and is substantially centered between a toe edge and a heel edge of the sole, andwherein the second weight member is located toward a back edge of the sole and is substantially centered between the toe edge and heel edge of the sole,wherein the non-weighted section completes the remainder of the sole,wherein the first and second weight members have a higher density than the non-weighted section of the sole or have a higher thickness than the non-weighted section of the sole to increase the moment of inertia of the golf club head,further comprising a cavity formed between the crown and the sole, andwherein the cavity forms a protrusion extending out from the skirt of the golf club head,wherein the sole further comprises four sections,wherein a first section has an edge coinciding with the entire face edge of the sole and which tapers as it extends back toward the back edge of the sole forming a waist and which then flutes slightly at its terminating edge, andwherein a second section has a bow-shape and a first edge coinciding and connecting with the terminating edge of the first section and a second edge that extends off of the sole, unconnected to the skirt or crown, to form the back edge of the sole such that the extremities of the bow-shaped second section extend beyond the terminal end of the crown of the golf club head to form the cavity between the crown and the sole, andwherein a third section comprises the area between the toe edge of the sole and the first section and which has a terminating edge that comprises a portion of the edge of said cavity, andwherein a fourth section comprises the area between the heel edge of the sole and the first section and which has a terminating edge that comprises a portion of the edge of said cavity.

Abstract
A golf club head having at least two discrete weight members positioned on the sole to optimize moment of inertia is disclosed. A first weight member is located toward and substantially parallel with the face edge of the sole. A second member is located toward the back of the sole and substantially centered between the heel and toe edges of the sole. In one embodiment, a golf club head includes a sole comprising four sections and wherein a rib of material connects two of said sections. In another embodiment, a golf club head includes a cavity formed between the crown and sole and having an opening at the back of the club head. In yet another embodiment, a golf club head is tapered to form a waist and has a back that has a bowed-shape.
