A method of forming a golf club head assembly includes aligning a faceplate with a recess of a club head; welding the faceplate to the club head; then, after welding the faceplate, heating the club head and the faceplate to at least a solvus temperature of the faceplate for a predetermined amount of time; and then, after heating the club head and the faceplate, allowing the club head and the faceplate to air cool.

Golf club head assembly

Golf club head

Disclosed herein is a golf club heads having a body portion and a face portion, wherein the face portion comprises a variable thickness profile disposed at an angle on the rear surface of the face plate.

Variable thickness face plate for a golf club head

A driver-type golf club head comprising a cube-like body shape, wherein a ratio between the body height and the body depth is between 0.5 and 0.75, and a ratio between the body height and the body width is between 0.5 and 0.75. The golf club head further comprises a mass distribution wherein a large portion of the club head mass is located within a central mass zone centered about the Y'-axis. The golf club head further comprises an Ixx and an Iyy moment of inertia, wherein and Ixx/Iyy ratio is greater than 0.8. In many embodiments, the golf club head further comprises optimized bulge and roll curvatures determined by the Ixx, Iyy, CG position, coefficient of restitution, and/or other characteristics.

Embodiments of golf coupling mechanisms for joining golf club heads and shafts are described herein. The golf coupling mechanism allows for adjustment of a club head loft angle, a club head lie angle, and a golf club shaft length while utilizing one club head and one shaft. In a fully extended configuration, the golf coupling mechanism includes a shaft sleeve, a removable spacer, and a removable extender, wherein a fastening assembly secures the golf coupling mechanism to the golf club head. In a contracted configuration, the golf coupling mechanism includes the shaft sleeve. The golf coupling mechanism further includes a shaft cap to soften the interaction between the shaft and the golf coupling mechanism. The golf coupling mechanism further comprises one or more arcuate coupler sets to frictionally lock the shaft relative to the golf club head.

Golf club heads with golf coupling mechanisms

A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

Adjustable length shaft and an adjustable mass for a golf club

Some embodiments include club heads having reinforced club head faces. In one example, the club head comprises a variable face thickness profile with thickened and thinned regions. The face includes a thinned perimeter region positioned near a perimeter of the face, and a thickened central region positioned over a geometric center of the face. The club head further comprises a 360 undercut that extends along the entire perimeter of the face. The club head further comprises one or more reinforcement ribs to improve the frequency response during golf ball impacts. The combination of the thinned perimeter region, thickened central region, and 360 undercut reinforces the club head while permitting the face to bend. Other embodiments of related club heads and methods are also disclosed.

Club heads having reinforced club head faces and related methods

A golf club head includes a hosel and a shaft sleeve insertable into the hosel, A shaft sleeve body of the shaft sleeve, the shaft sleeve body includes an outer wall and a first coupler protruding from the sleeve outer wall and having a first coupler surface area, a second coupler protruding from the sleeve outer wall and having a second coupler surface area, a third coupler protruding from the sleeve outer wall and having a third coupler surface area, and a fourth coupler protruding from the sleeve outer wall and having a fourth coupler surface area. Each of the first second, third and fourth couplers has an arcuate surface continuously curved throughout its respective surface area.

Golf club heads with hosel inserts and related methods

Some embodiments include a first golf club head and a second golf club head. The first golf club head includes a body having a face portion, and the second golf club head includes a body having a face portion. Meanwhile, the first club face portion comprises a face surface and at least one first club groove, and the second club face portion comprises a face surface and at least one second club groove. An edge radius of the first club head groove(s) can be less than an edge radius of the second club head groove(s), a base width of the first club head groove(s) can be less than a base width of the second club head groove(s), and/or a sidewall angle of the first club head groove(s) can be greater than a sidewall angle of the second club head groove(s). Other embodiments of related club heads and methods are also disclosed.

Club heads with varying groove parameters and related methods

Described herein is a golf club head comprising reinforcement members. The reinforcement members span across a rear cavity to connect to at least two portions of the perimeter of the club head and do not touch the rear surface of the strike face. The reinforcement members can be integrally casted or separately formed and attached to the club head. The reinforcement members improve the sound and vibrational response of the club head.
