Benefits of technology

The patent is about a golf club head that has internal structures that connect the crown section to the sole section to reduce stress in the hitting face section when hitting the golf ball. These internal structures can be made of hollow tubes or solid rods made of titanium alloy. This design helps improve the performance and accuracy of the golf club.

Problems solved by technology

However, the prior art fails to disclose an interior structure that increases ball speed through reducing stress in the striking face section at impact, with a minimal increase in mass to the golf club head.

Embodiment Construction

[0025]As shown in FIGS. 1-8, a preferred embodiment of the golf club head 10 of the present invention is generally designated. The golf club head 10 includes a body 20 having a striking face section 30 with a face center 34, a return section 32 extending rearwards away from an upper edge 31 of the striking face section 30, sole section 22 extending rearwards away from a lower edge 33 of the striking face section 30, a hosel 24 for engaging a shaft, a heel end 23, a toe end 25, an upper opening 26, a hollow interior 27, and an aft end 28. A crown section 40 is comprised of the return section 32 and a crown insert 42 that is placed over the upper opening 26 to enclose the hollow interior 27. The body 20 also includes three cutouts 70, 72, 74 in a center area 21 of the sole section 22, which are closed by a cover piece 80 having a density that is lower than the density of the material used to make the body 20. Each of the crown section 40 and cover piece 80 preferably is composed of a ...

Abstract

A golf club head comprising a body and a plurality of stiffening members and satisfying the equation Vballnorm≧0.0356x+140.82 is disclosed herein. The body comprises a face section, a sole section, and a crown or return section, and defines a hollow interior. Each of the plurality of stiffening members extends from the crown or return section to the sole section within the hollow interior to reduce stresses placed on the face section during impact with a golf ball. The stiffening members are all located within 1 inch of a rear surface of the face section measured along a plane normal to the center of the face, and are spaced a distance of 0.500 to 2.00 inch from one another within the hollow interior.
