Abstract:
A golf club head comprising a body, a variable face thickness pattern, and a plurality of solid metal stiffening rods, and which satisfies the equation V ballnorm ≥0.0356x+140.82, is disclosed herein. The body comprises a face, a sole, and a return section, and defines a hollow interior. Each of the rods extends from the return section to the sole within the hollow interior proximate the face to reduce stresses placed on the face during impact with a golf ball. The rods are all located within 1 inch of a rear surface of the face 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. The variable face thickness pattern preferably comprises a plurality of concentric rings, with a center ring having a thickness that is less than a thickness of an intermediary ring.

Claim (Index 1):
A golf club head comprising:\n a body comprising a striking face section, a sole section extending from a lower edge of the striking face section, a return section extending from an upper edge of the striking face section, an upper opening, and an aft end opposite the striking face section, the return section disposed between the striking face section and the upper opening; a crown section affixed to the body to close the upper opening and define a hollow body interior; and a stiffening member disposed within the hollow body interior and extending from the return section to the sole section, the stiffening member comprising an upper end connected to the return section and a lower end connected to the sole section, wherein the striking face section comprises an interior surface facing the hollow interior, a geometric center, a face boundary, a central thickness region having a first thickness, a first intermediate thickness region having a second thickness, and a second intermediate thickness region having a third thickness, wherein the face boundary comprises the upper and lower edges of the striking face section, wherein the first thickness is greater than the second thickness and less than the third thickness, wherein the first thickness ranges from 0.100 inch to 0.150 inch, wherein the second thickness ranges from 0.020 inch to 0.100 inch, wherein the third thickness ranges from 0.130 inch to 0.170 inch, wherein no portion of the stiffening member is spaced further than 0.500 inch from the interior surface along a vertical plane extending perpendicular to the striking face section, and wherein no portion of the stiffening member makes contact with the striking face section during impact with a golf ball.
