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 11):
A wood-type golf club head comprising:\n a metal body comprising a striking face section with a face boundary, a sole section extending from a lower portion of the face boundary, a return section extending from an upper portion of the face boundary, 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 first and second solid metal rods disposed within the hollow body interior, wherein each of the first and second solid metal rods extends from the return section to the sole section, wherein no portion of either of the first and second metal rods is spaced further than 0.500 inch from the interior surface along a vertical plane extending perpendicular to the striking face section, wherein the first solid metal rod is spaced from the second solid metal rod a distance of 0.500 inch to 2.00 inches along a y-axis extending parallel with the striking face section, wherein the striking face section comprises an interior surface facing the hollow body interior, a geometric center, a first ring having a first thickness encircling the geometric center, a second ring having a second thickness encircling the first ring, a third ring having a third thickness encircling the second ring, and a fourth ring having a fourth thickness encircling the third ring, wherein the first ring is defined as an area of the striking face section located between the geometric center and 25% of a radial distance from the geometric center to the face boundary, wherein the second ring is defined as an area of the striking face section located between 26% and 59% of a radial distance from the geometric center to the face boundary, wherein the third ring is defined as an area of the striking face section located between 60% and 90% of a radial distance from the geometric center to the face boundary, wherein the fourth ring is defined as an area of the striking face section located between 90% and 100% of a radial distance from the geometric center to the face boundary, wherein the first thickness is greater than the second thickness and less than the third thickness, wherein the fourth thickness is greater than the second thickness and less than the first thickness and the third thickness, and wherein the wood-type golf club head has a characteristic time of less than 257 \u03bcs.
