A golf club head includes: a sole; a crown; a toe; a heel opposite the toe; a strike face generally bounded by a face perimeter edge, the strike face comprising a geometric center; a rear portion; and a substantially enclosed interior cavity at least partially delimited by the sole, the crown, the strike face, and the rear portion. The golf club head also includes at least one rib having a first portion secured to the strike face, having a second portion secured to the crown, and being positioned such that a location on the strike face laterally spaced toe-ward from the geometric center by no less than 0.4 in is associated with a COR value no less than 0.825.

Golf club head

An exemplary golf club head having an increased amount of discretionary mass may be realized by utilizing improved drop angles, an improved average crown height, and/or articulation points. The discretionary mass may be placed low and deep in the club head to improve the location of the center of gravity as well as the inertial properties. A preferred break length may also be utilized to further improve the depth of the center of gravity. In one example, the center of gravity may be positioned to substantially align the sweet spot with the face center of the club head.

A hollow golf club head having face end and tail ends, a strike face at the face end, a crown, a sole, and a structural response modifying constraining member having first and second ends, the second being forward of the first and spaced from the strike face, the constraining member extending vertically and in contact with the sole and the crown at its first and second ends, and extending horizontally distance that is substantially less than the sole length, when the club head is in address position.

Structural response modifying features of a golf club head

A hollow golf club head includes a sole, a crown, a skirt, and a striking face. The golf club includes a junction interconnecting the sole, crown, and skirt to the striking face, the junction including at least one stiffening member.

A hollow golf club head having face end and tail ends, a strike face at the face end, a crown, a sole of length &#x3e;3.5 inches, volume 0.300 cm, and a structural response modifying constraining member having first and second ends, the second being forward of the first and spaced from the strike face, the constraining member extending vertically and in contact with the sole and the crown at its first and second ends, and extending horizontally a maximum distance that is &#x3c;40% of the sole length, when the club head is in address position.
