Benefits of technology

[0005] The present invention comprises a golf club head formed of a hollow body having a metallic face and a rear body portion forming a shell at least a portion of which is made of a metal-organic composite material. According to a preferred embodiment, the rear body portion of the club head includes a metallic stringer that extends along a 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. In the pre...

Problems solved by technology

The lightweight plastic rear body enables more metal to be dedicated to the striking face, however, many golfers dislike the impact sound produced by a club head having a low resonance, highly damped non-metallic rear body.
Moreover, because of the discontinuity between the all-composite or thermoplastic rear body and the striking face, the striking face is not significantly supported by the rear body.

Embodiment Construction

[0016] The drawing figures are intended to illustrate the general manner of construction and are not necessarily to scale. In the detailed description and in the drawing figures, specific illustrative examples are shown and herein described in detail. It should be understood, however, that the drawing figures and the detailed description are not intended to limit the invention to the particular form disclosed but are merely illustrative and intended to teach one of ordinary skill how to make and / or use the invention claimed herein and for setting forth the best mode for carrying out the invention.

[0017] With reference to FIGS. 1-7, and in particular FIGS. 1 and 2, golf club head 10 comprises a hollow body 12 formed of a metal material having a front wall including a face 14 for impacting a golf ball, and a hose 16 adapted to receive a golf club shaft (not shown). Hollow body 12 further comprises a rear body portion 18, which is made up of a crown 20, a sole 22 and a skirt 24 that f...

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.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates generally to golf clubs and, in particular, to so-called metal wood drivers. [0002] Recent developments in golf club design have included improvements in drivers, which are clubs used primarily to strike a golf ball resting on a golf tee. These improvements have resulted in drivers with club heads consisting of a hollow shell usually made of metal, such as steel, aluminum, or titanium. One example of a golf club head consisting of a hollow metal shell is disclosed in U.S. Pat. No. 5,851,160 to Rugge, et al. In an effort to obtain better and better performance from these hollow metal wood drivers, however, golf club manufactures have increased the head volume from a moderate volume of 250 cubic centimeters as disclosed in Rugge, et al. to over 400 cubic centimeters in recent years. The striking face of a metal wood driver must be of a certain minimal thickness in order to withstand the impact forces generated upon impact with ...
