Problems solved by technology

Since the height of the faceplate is relatively short, even a partial loss of flexibility has a significant adverse effect on the overall springiness of the faceplate.
It is also known that optimum directional accuracy of a wood shot can be attained when impact occurs at the center sweet spot of the club face, but that an off-center hit which is offset toward the toe or heel of the club, can cause the club to twist, thereby causing the shot to hook or slice.

Embodiment Construction

[0032] Depicted in FIGS. 1-6 is a head 10 of a fairway wood comprising a stainless steel body 12, and a titanium alloy face member 14 attached to a front side thereof. The face member 14 is cup-shaped in that it comprises a front portion 16 and a rim or lip 18 projecting rearwardly from an outer periphery of the front portion. A rearwardly-facing rear edge 18a of the rim 18 (see FIG. 10) is bonded by silver-nickel brazing 22 to a forwardly-facing seat 20 of the body 12. The seat 20 is bordered inwardly by a forwardly-projecting ridge 21 of the body which extends endlessly around the seat 20.

[0033] The shapes of the seat and the mating surface of the rim can vary. For example, the forwardly facing seat of the body could comprise a forwardly open recess 20′ disposed between two endless ridges 21′, 21″ of the body as shown in FIG. 3a. The rear edge of the rim 18 would include a rearwardly projecting rib 22′ that fits into the recess 21′. As in the case of FIGS. 1-6, the rear edge of t...

Abstract

A fairway wood head comprises a stainless steel body and a cup-shaped titanium alloy face member attached by silver-nickel brazing to the body. The face member is preferably of variable thickness, being thicker at it's center than at it's outer periphery. Weights are attached at the toe and heel, respectively, of the body, to resist twisting of the head during an off-center hit. Weights are attached in the sole of the body on opposite sides of a front-to-rear center line of the head to lower the center of gravity of the head. The head has a hosel which includes a stainless steel inner portion and a titanium alloy outer sleeve portion disposed around and attached to the inner portion.

Description

[0001] The present invention claims priority under 35 U.S.C. §119 and / or §365 to U.S. Provisional Application Serial No. 60,633,322 filed on Dec. 6, 2004.BACKGROUND [0002] The present invention relates to golf clubs and, in particular, to fairway woods. The invention especially relates to fairway woods having a head comprised of a stainless steel body and a titanium front face. [0003] Fairway woods are known whose head includes a titanium alloy faceplate attached to a stainless steel body. The use of titanium alloy for the faceplate reduces the weight of the club head, enabling faster head speed to be attained, as well as enabling the front face to perform a spring action for increased distance. [0004] As shown in FIG. 9, it is also known to employ a titanium alloy faceplate 30 of variable thickness whose center region is thicker than the outer peripheral portion thereof. That enables the club face to perform an enhanced spring action which further increases the distance of a fairwa...
