Metal-organic composite golf club head
First Claim
1. A golf club head comprising:
- a hollow body made of high density material, said hollow body having a heel end, a toe end, a front wall and a rear body portion;
said rear body portion including a crown, a sole, a skirt extending between said crown and said sole, and an arcuate perimeter region formed where said crown and said skirt meet;
a stringer spaced radially inwardly from said arcuate perimeter region and a plurality of ribs connecting said arcuate perimeter region and said stringer;
said arcuate perimeter region, said stringer and said ribs defining a lattice which includes a plurality of apertures formed in said crown; and
low density material filling said apertures in said lattice.

Abstract
A golf club head is formed of a hollow body, the rear body portion of which includes a metallic stringer that extends along the crown-skirt interface and a plurality of ribs intersecting the metallic stringer to form a lattice frame, the openings of which are filled with an organic composite material such as graphite epoxy. An additional aperture formed in the skirt is also filled with the same graphite epoxy material. Because the graphite epoxy is lighter than the surrounding metal frame, the rear body portion of the golf club head is lighter than a comparable all metal club head. Yet, the presence of the metallic stringer and frame renders the metal-organic composite rear body portion substantially stiffer than a comparable all-composite rear body portion.

11. A golf club head comprising:
-
a hollow body made of high density material, said hollow body having a heel end, a toe end, a front wall and a rear body portion;
said rear body portion including a crown, a sole, a skirt extending between said crown and said sole, and an arcuate perimeter region formed where said crown and said skirt meet;
a stringer spaced radially inwardly from said arcuate perimeter region and a plurality of ribs connecting said arcuate perimeter region and said stringer, said stringer extending from proximate the toe end of said hollow body in a direction that is substantially parallel to said arcuate perimeter region;
said arcuate perimeter region, said stringer and said ribs defining a lattice which includes a plurality of apertures formed in said crown, one of said apertures being located proximate the toe end of said hollow body, none of said apertures being located proximate the heel end of said hollow body; and
low density material filling said apertures in said lattice. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
