A golf club head with improved striking face is disclosed. More specifically, the present invention relates to a golf club head wherein the striking face is further comprised out of a thickened central region, located near a geometric center of the striking face portion, a central transition region extending outward radially from the thickened central region, a thinned intermediate region, extending outward radially from the central transition region, a thickened stress reducing region, extending outward radially from the thinned intermediate region, and a thinned perimeter region, extending outward radially from the thickened stress reducing region, all of which combine to form the improved striking face.

Golf club head with improved striking face

A golf club head includes: a striking face including a front surface configured to strike a golf ball and a rear surface opposite to the front surface; a periphery portion surrounding and extending rearwards from the striking face; a cavity at least partially enclosed by the striking face and the periphery portion; a support arm extending at least partially through the cavity from the periphery portion and being spaced apart from the rear surface of the striking face; a first damping element between a first side of the support arm and the rear surface of the striking face; and a second damping element on a second side of the support arm opposite to the first side of the support arm.

Golf club having a damping element for ball speed control

A golf club head having a supported striking face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a striking face, an internal support layer, and an intermediary sandwiched layer juxtaposed between the striking face and the internal support layer.

Golf club head having supported striking face

A multi-piece, multi-material golf club head is disclosed herein. More specifically, the golf club head in accordance with the present invention utilizes multiple pieces of different materials to form a frontal portion of a golf club head, allowing more of the frontal portion of the golf club head to be made out of a lightweight material to match the lightweight material of the aft body of the golf club head.

Multi-piece golf club head

A golf club head with improved striking face performance is disclosed herein. More specifically, a golf club head includes a striking face with a thickened central region surrounded by transition region that reduces radially in thickness as it extends away from the central region is disclosed. The striking face geometry results in more uniform characteristic time measurements across a large percentage thereof.

Golf club head with improved variable thickness striking face

A golf club head having a multi-layered striking face is disclosed herein. More specifically, the golf club head in accordance with the present invention has an external frontal face layer, an internal rear face layer, and an intermediary sandwiched face layer juxtaposed between the external frontal face layer and the internal rear face layer. The intermediary sandwiched face layer may generally be made out of a high flexural modulus polymeric material.

Golf club head having multi-layered striking face

A golf club head having a slot in the sole filled with an insert in which the slot is positioned close to the striking face. The slot can be a uniform distance from the striking face or the slot can curve away from the striking face in the toe region. The insert can have a uniform height or a non-uniform height. Inserts with uniform heights can have a low height profile. Inserts with non-uniform heights can have a lower height in a central portion of the insert compared to an edge portion or a perimeter portion of the insert. The insert can also have flanges or protrusions for installation into the slot. The resulting golf club head improves performance, as the sole slot with insert allows the striking face to have a profile that meets the needs at that location.

Iron with sole slot

A golf club head with improved striking face is disclosed. More specifically, the present invention relates to a golf club head comprising multiple materials, wherein a gasket is placed in between a body portion of the golf club head and a face insert of the golf club head. The gasket being made of a different material than the body portion or the face insert. The construction providing reduced stress in the face insert, manipulation of performance characteristics, and improved sound and feel.

A golf club head including a striking face, a periphery portion surrounding and extending rearwards from the striking face, a damping element including a front surface and a rear surface, the rear surface of the damping element opposite the front surface of the damping element, wherein the striking face comprises a first portion having a substantially constant thickness, wherein the front surface of the damping element comprises a geometric center, wherein the striking face comprises a second portion, the second portion of the striking face located heelward of the center face plane, the second portion of the striking face having a thickness which tapers from a maximum thickness at a thick end of the second portion to a minimum thickness at a thin end of the second portion, wherein the thick end is located toeward of the thin end.
