Abstract
A golf club head has a stranded structure such as a cantilevered strand or a beam strand. The stranded structure causes changes in acoustic properties from that of a standard golf club. A gap or through-hole around the stranded structure may be filled with a vibration dampening material, such as flexible polymer, to further adjust the acoustic properties of the golf club. Vibration frequency regions in a golf club may be modified by incorporating stranded structures in the vibration frequency regions.
Claims20
A golf club head comprising:
- a crown;
- a club face connected to the crown;
- and
- a sole connected to and disposed opposite the crown, wherein the crown, the club face, and the sole at least partially define an interior void, and wherein at least one of the crown and the sole define:
- at least one stranded structure having an unsupported middle portion and at least one supported end, wherein the at least one stranded structure has a length to width ratio of at least 10:1 and the at least one stranded structure is an elongated cantilevered structure or a beam structure,
- wherein the unsupported center of the at least one stranded structure is separated on both sides from at least one of the crown and the sole by a through-hole and the at least one supported end is fixed to the at least one of the crown and the sole.

A golf club head comprising:
- a metal club face;
- a metal crown connected to the metal club face;
- a metal sole connected to the metal club face, wherein the metal club face, the metal crown, and the metal sole at least partially define an interior void;
- and
- a through-hole in communication with the interior void and defined by an elongated cantilevered or beam strand, wherein the elongated cantilevered or beam strand is defined by at least one of the metal crown and the metal sole, wherein elongated cantilevered or beam strand includes a supported end, an unsupported center portion, and an unsupported end, wherein the through-hole defines a gap that separates the unsupported center portion and the unsupported end from a remainder of the at least one of the metal crown and the metal sole.
2 more elements
A golf club head comprising:
- a crown having an outer crown surface and an inner crown surface;
- a hosel attached to the crown and configured to receive a golf club shaft;
- a sole having an outer sole surface and an inner sole surface, the sole connected to and disposed opposite the crown;
- a club face attached to the sole and the crown such that the crown, the club face, and the sole at least partially define an interior void;
- and
- a first cantilevered stranded structure, having a strand length and a strand width, defined by the sole, wherein the first cantilevered stranded structure includes an unsupported end, an unsupported center portion, and an unsupported end, wherein the unsupported end and the unsupported center portion are adjacent a through-hole through the sole into the interior void, the through-hole defining a gap having a gap width.
