Benefits of technology

[0036] The present invention provides a golf club head with a striking plate having a high coefficient of restitution in order to increase the post-impact velocity of a golf ball for a given pre-impact club head velocity. The present invention is able to accomplish this by using a striking place composed of three materials, including a lightweight composite material.

Problems solved by technology

Most of the energy is transferred from the head to the golf ball, however, some energy is lost as a result of the collision.
However, this leads to greater deformations in the golf ball, and thus increases in the energy transfer problem.
Although the prior art has disclosed many variations of multiple material club heads, the prior art has failed to provide a multiple material club head with a high coefficient of restitution and greater forgiveness for the typical golfer.

Embodiment Construction

[0055] As shown in FIG. 1, a golf club is generally designated 40. The golf club 40 has a golf club head 42. When designed as a driver, the club head 42 preferably has a volume from 200 cubic centimeters to 600 cubic centimeters, more preferably from 300 cubic centimeters to 500 cubic centimeters, and most preferably from 350 cubic centimeters to 480 cubic centimeters. The volume of the golf club head 42 will also vary between fairway woods (preferably ranging from 3-woods to eleven woods) with smaller volumes than drivers. The golf club head 42 preferably has a mass no more than 225 grams, and most preferably a mass of 180 grams to 215 grams. Engaging the club head 42 is a shaft 48 that has a grip, not shown, at a butt end and is inserted into a hosel 54 (FIG. 13A) at a tip end 56.

[0056] As shown in FIGS. 1-9, the club head 42 is generally composed of a face cup assembly 59 and an aft-body 61. The face cup assembly 59 is composed of a striking plate 58, a face component 60, and a ...

Abstract

A golf club (40) having a club head (42) with a face cup assembly (59) and an aft-body (61). The face cup assembly (59) includes a face component (60) with a striking plate (58) and a reinforcing plate (57) mounted thereto. The aft-body (61), which is composed of a non-metal material, such as a composite material or a thermoplastic material, includes a crown portion (62), a sole portion (64) and an optional ribbon section (90). The face component (60) and the reinforcing plate (57) are composed of metal materials, while the striking plate (58) is preferably composed of a composite or thermoplastic material.

Description

CROSS REFERENCES TO RELATED APPLICATIONS [0001] This application claims priority to U.S. Patent Application No. 60 / 594,449, filed on Apr. 8, 2005.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not Applicable BACKGROUND OF THE INVENTION [0003] 1. Field of the Invention [0004] The present invention relates to a golf club, particularly to a golf club face which has a striking plate composed of a plurality of materials. More specifically, the present invention relates to a golf club head composed of three materials for a high performance face at a lower production cost. [0005] 2. Description of the Related Art [0006] When a golf club head strikes a golf ball, large impacts are produced that load the club head face and the golf ball. Most of the energy is transferred from the head to the golf ball, however, some energy is lost as a result of the collision. The golf ball is typically composed of polymer cover materials (such as ionomers) surrounding a rubber-like c...
