Abstract

A golf club head comprising a body and a plurality of stiffening members is disclosed herein. The body comprises a face section, a sole section, and a crown section, and defines a hollow interior. Each of the plurality of stiffening members extends from the crown section to the sole section to reduce stresses placed on the face section during impact with a golf ball. The stiffening members are all located within 0.500 inch of a rear surface of the face section measured along a plane normal to the center of the face, and within 1 inch of the center of the face section along a horizontal axis parallel to the face section.

First claim

We claim:

1 . A golf club head comprising:
a body comprising a striking face section, a sole section and a crown section, the body defining a hollow interior; and at least one stiffening member extending from the crown section to the sole section, wherein the striking face section comprises a face center and a rear face surface facing the hollow interior, wherein the crown section comprises at least one crown aperture, wherein the at least one crown aperture corresponds to the at least one stiffening member, and wherein the at least one stiffening member is located less than 0.500 inch from the rear face surface along a vertical plane extending through the face center perpendicular to the striking face section.

2 . The golf club head of claim 1 , wherein the at least one stiffening member comprises at least first, second, and third stiffening members.

3 . The golf club head of claim 2 , wherein each of the first, second, and third stiffening members comprises a structure selected from the group consisting of a solid cylindrical rod and a hollow tube.

4 . The golf club head of claim 3 , wherein the solid cylindrical rod is composed of a metal material and wherein the hollow tube is composed of a material selected from the group consisting of composite and titanium alloy.

5 . The golf club head of claim 2 , wherein the first stiffening member is located no more than 0.25 inch away from the face center along a horizontal axis extending parallel to the striking face section.

6 . The golf club head of claim 5 , wherein each of the second and third stiffening members is located no more than 1 inch away from the center of the face along the horizontal axis.

7 . The golf club head of claim 1 , wherein the at least one stiffening member is an elongated cartridge comprising an upper portion, a lower portion, and a middle portion that extends parallel to the striking face section.

8 . The golf club head of claim 7 , wherein the sole comprises a sole aperture, wherein the sole aperture corresponds to the lower portion of the elongated cartridge, and wherein the at least one crown aperture corresponds to the upper portion of the elongated cartridge.

9 . The golf club head of claim 7 , wherein the middle portion is a hollow rectangular structure, and wherein the elongated cartridge is composed of a material selected from the group consisting of composite and titanium alloy.

10 . The golf club head of claim 7 , wherein the middle portion comprises at least two vertical rods extending between the upper portion and the lower portion.

11 . The golf club head of claim 10 , wherein the middle portion comprises at least two diagonal rods extending between the at least two vertical rods.

12 . The golf club head of claim 7 , wherein the middle portion comprises at least two piston assemblies.

13 . A golf club head comprising:
a body comprising a striking face section, a bottom section, and a top section, the body defining a hollow interior; and a plurality of stiffening members, each of the plurality of stiffening members extending from the top section to the bottom section, wherein the striking face section comprises a face center and a rear face surface facing the hollow interior, wherein the top section comprises a plurality of apertures, wherein each of the plurality of apertures corresponds to a stiffening member of the plurality of stiffening members, wherein the plurality of stiffening members comprises a first stiffening member, a second stiffening member, and a third stiffening member, and wherein the first stiffening member is located no more than 0.25 inch away from the face center along a horizontal axis extending parallel to the striking face section.

14 . The golf club head of claim 13 , wherein each of the second and third stiffening members is located no more than 1 inch away from the center of the face along the horizontal axis.

15 . The golf club head of claim 13 , wherein at least one of the plurality of stiffening members is selected from the group consisting of a solid cylindrical rod and a hollow tube.

16 . The golf club head of claim 15 , wherein each of the plurality of stiffening members is a solid cylindrical rod composed of a metal material.

17 . The golf club head of claim 16 , wherein each of the plurality of stiffening members is located less than 0.500 inch from the rear face surface along a vertical plane extending through the face center perpendicular to the striking face section.

18 . The golf club head of claim 13 , wherein the bottom section comprises a plurality of bosses extending into the hollow interior, and wherein each of the plurality of bosses corresponds to a stiffening member of the plurality of stiffening members.

19 . The golf club head of claim 13 , wherein each of the plurality of stiffening members has a length ranging from 1 inch to 2.5 inches.
