A golf club head includes: a body including: a striking face having a lower edge and an opposite upper edge; a sole extending from the lower edge; and a crown extending from the upper edge, wherein the striking face, the sole, and the crown, define at least part of an outer surface of the body; a recessed channel formed in the outer surface; and a weight assembly including: a weight; a cover extending at least partially over the recessed channel; and a threaded fastener configured to engage with the cover and to move the cover between a locked position and an unlocked position, wherein the weight is slidably engaged with the cover such that the weight moves with the cover between the locked position and the unlocked position, and wherein the weight assembly is configured such that the weight is slidable relative to the cover when the cover is in the unlocked position.

Golf club having an adjustable weight assembly

A golf club head with a crown comprising an inner crown portion and an outer crown portion. The inner crown portion may be made of a low density or low elastic modulus material. The outer portion of the crown defines an opening to the cavity. The inner portion of the crown is attached to the outer portion of the crown such that the opening is covered by the inner portion of the crown.

Golf club having a low modulus crown

A golf club head includes a body including: a striking face and a sole; a recessed channel formed in the sole and having a first sidewall, wherein one or more dimples are formed in the first sidewall; a weight assembly including: a weight at least partially disposed within the recessed channel, a cover adapted to releasably secure the weight within the recessed channel, and a fastener coupling the cover to the body, wherein the cover is positionable in at least: an unlocked configuration whereby the cover is raised at least partially out of the recessed channel; and a locked configuration whereby the cover is at least partially disposed within the recessed channel and a gap between the sole and a portion of an exterior surface of the cover proximal to the first sidewall is within a range of 1.0 mm to 1.5 mm.

A golf club head includes a body having a recessed channel formed in an outer surface. A weight assembly that includes a weight at least partially disposed within the recessed channel, a cover extending at least partially over the recessed channel, and a fastener coupling the cover to the body. The fastener is adapted to retain the weight in the recessed channel only indirectly by the cover. The weight is slidably engaged with the cover and the cover is positionable in at least an unlocked configuration whereby the cover is raised at least partially out of the recessed channel and the weight is selectively slidable within the recessed channel, and a locked configuration whereby the cover is at least partially disposed within the recessed channel and the weight is secured within the recessed channel. The weight moves with the cover between the unlocked configuration and the locked configuration.

A golf club head with a crown comprising an inner crown portion and an outer crown portion. The inner crown portion may be made of a low density or low elastic modulus material. The outer portion of the crown defines an opening to the cavity, a riser extending into the cavity, and a ledge extending from the edge of the riser. The ledge may define a first channel and a second channel that extend around the ledge. The first channel is filled with adhesive to secure the inner portion of the crown to the ledge. The inner portion of the crown is attached to the ledge such that the opening is covered by the inner portion of the crown. The golf club head may also have a sole comprising an inner sole portion and an outer sole portion.

A golf club head includes a body, a recessed channel, and a weight assembly. The weight assembly has a weight, a cover, and a fastener coupling the cover to the body. The cover includes a first end, a second end, and a rabbet extending at least partially between the first end and the second end. The rabbet formed by at least two walls and sized and shaped to at least partially receive the weight and allow the weight to slide therein. One or more of the at least two walls have a retention rib extending therefrom. The retention rib is elongated in a direction between the first end and the second end and discontinuous in the elongated direction. The fastener is configured to move the cover between at least two positions, a first position whereby the weight is selectively slidable and a second position whereby the weight is secured.

A golf club head includes a body having a recessed channel formed in the outer surface. A weight assembly that includes a weight disposed within the recessed channel and a cover extending over the recessed channel. A shelf is defined in the cover and slidably receives the weight. The weight assembly also includes a fastener coupling the cover to the body. The fastener is adapted to retain the weight in the recessed channel only indirectly by the cover. The cover is positionable in an unlocked configuration whereby the cover is raised at least partially out of the recessed channel and the weight is slidable within the shelf and the recessed channel, and a locked configuration whereby the cover is disposed within the recessed channel and the weight is secured within the recessed channel and the shelf. The weight moves with the cover between the unlocked configuration and the locked configuration.

A golf club head made out of multi-material is disclosed herein. More specifically, the golf club head in accordance with the present invention has at least a portion of the body of the golf club head that is further comprised out of a base layer and a lightweight cover layer. The base layer may have a plurality of cutouts to help reduce unnecessary mass and the lightweight cover layer may be made out of an ultra-lightweight material to further reduce the unnecessary mass. The resulting golf club head may generally have a deep CG wherein the CG-B location is about 37 mm, and a CG-C location is greater than about 25 mm.

The resulting golf club head may generally have a deep CG wherein the CG-B location is about 37 mm, and a CG-C location is greater than about 30 mm.

A golf club with a new innovative construction to attach a high density weight to an external surface of the sole of a golf club head is disclosed herein. More specifically, the present invention relates to utilizing a thickened sole portion having a specific surface area to thickness ratio to provide adequate support for a high density weight having a significant amount of mass. The new innovative method of attachment also incorporates a unique mechanical lock to properly secure the high density weight to the club head, as materials used for high density weighting may not be easily weldable to the titanium material currently used for metalwood type golf club head.
