Benefits of technology
[0013] This arrangement of inner and intermediate zones forms an area of relatively high flexural stiffness in the direction of high heel to low toe, thereby creating high resilience in the direction of high toe to low heel. In other words, this arrangement creates a gradient of flexural stiffness in the direction of high toe to low heel, and produces a desirable effect of manipulating resilience or higher coefficient of restitution (COR) in that direction. This area of improved coefficient of restitution advantageously coincides with the ball impact pattern that golfers typically make on the hitting face.
Problems solved by technology
However, these environmental effects are beyond the control of the golf equipment manufacturer.
Furthermore, the accuracy of conventional clubs is highly dependent on impact location.
However, there is no teaching to align the coefficient of restitution of the golf club head to the ball impact pattern.

example
[0076] In this example, hitting face 16 has the following construction. The central zone 36 has a substantially parallelogram shape, as shown in FIG. 10(a), with a major axis measuring about 3 inches and a minor axis about 0.75 inches with a thickness T1, of about 0.120 inch. The central zone 36 has a concentric transition zone 37 with a similar shape as the central zone 36. The intermediate zone 38 surrounds the central and transition zones with a thickness T2 of 0.080 inch and comprises the remainder of the face hitting area. There is no perimeter zone 40 included in this example. The major axis of zone 36 substantially coincides with the major axis of zone 38, and these two major axes form angle theta (θ) of about 50° with the shaft axis. Furthermore, zones 36 and 37 comprise about 18% of the total face surface area. A single homogeneous material, preferably a titanium alloy, with a Young's modulus (E) of approximately 16.5×106 lbs / in2 is used. In this example, the (FS1 / FS2) rati...

Abstract
A metal wood golf club head adapted for attachment to a shaft, comprising of a body portion and a crown portion, each portion constructed of a different density material. Combining a high-density material in the body portion, with a low-density material in the crown portion, creates an ultra-low center of gravity relative to the geometric face center, resulting in higher launch angles and spin rate ratios. The material for the crown portion is preferably a composite. The crown portion comprises an inner surface layer of a vibration dampening material. The transverse surfaces of the crown and body portions creating a gap that is filled with a shock absorption material such as putty or a rubber based structural adhesive.
Description
CROSS-REFERENCE TO RELATED APPLICATION [0001] The present application is a divisional of U.S. patent application Ser. No. 10 / 799,118, filed on Mar. 12, 2004, which is a continuation-in-part of U.S. patent application Ser. No. 10 / 428,061, filed on May 1, 2003, and now U.S. Pat. No. 7,029,403, which is a continuation-in-part of U.S. patent application Ser. No. 09 / 551,771 filed on Apr. 18, 2000, and now U.S. Pat. No. 6,605,007. The disclosures of the parent patent applications are incorporated herein in their entirety.FIELD OF THE INVENTION [0002] The present invention relates to an improved golf club head. More particularly, the present invention relates to a golf club head with an improved striking face and improved shock absorption between the mating portions making up the body of the club head. BACKGROUND [0003] The complexities of golf club design are well known. The specifications for each component of the club (i.e., the club head, shaft, hosel, grip, and sub-components thereof)...
