A hollow golf club head includes a metallic front body coupled with a composite rear body. The front body includes a strike face and a surrounding frame that extends rearward from a perimeter of the strikeface. The rear body includes a crown member coupled with a sole member. The sole member can have a structural layer formed from a filled thermoplastic material. The crown member can have structural layer and/or a resilient layer. The structural and resilient layers can be formed from fiber-reinforced thermoplastic composite material. The sole member has an opening through which a metallic weight pad at least partially extends. The weight pad is bonded to the structural layer and includes an aperture for attaching a metallic weight.

Mixed material golf club head

A driver-type golf club head having a reduced strike face height and a reduced strike face thickness produces a greater golf ball launch speed while maintaining a conforming CT value. In addition, the driver-type golf club head preserves or improves the club head durability, ball flight path optimization, and forgiveness by careful club head mass distribution.

Golf club head with improved characteristic time

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

Embodiments of golf club face plates with internal cell lattices are presented herein. Each cell of the plurality of cells can comprise a cell height measured in a direction from the outer skin to the inner skin. The cell height of each cell of the plurality of cells varies among the plurality of cells. Aa target strike region can be devoid of a cell of the cell lattice. Other examples and related methods are also disclosed herein.

Golf club face plates with internal cell lattices and related methods

Described herein is a golf club head comprising a composite material, the golf club head further comprising: a front end having a bottom rail, a top rail, and a strikeface, the strikeface including a striking surface, a back surface, and a reinforcement element extending from the back surface of the strikeface; a rear end opposite the front end; a heel portion; a toe portion opposite the heel portion; a sole coupled to the front end along the bottom rail at a sole transition region, the sole extending toward the rear end of the golf club head and including a sole thickness, a first weight member and a second weight member, and a perimeter wall extending from the front end near the heel portion to the front end near the toe portion along the rear end of the golf club head, wherein the perimeter wall decreases in height from the front end toward the rear end of the golf club head.

Golf club head with open crown and related methods

Described herein are embodiments of golf club heads with flexible soles. In one embodiment, the golf club head includes a body having a crown opposite a sole, a toe opposite a heel, a back end opposite a front end, and a hosel. The golf club head also includes a sole curvature profile comprising a radius of curvature that varies as the sole curvature profile extends between the front end and the back end. The radius of curvature is configured to increase the flexure of the entire golf club head, thereby increasing the internal energy of the golf club head.

Golf club head with flexible sole

A hollow golf club head includes a metallic front body coupled with a composite rear body. The front body includes a strike face and a surrounding frame that extends rearward from a perimeter of the strikeface. The rear body includes a crown member coupled with a sole member. The sole member has a structural layer formed from a filled thermoplastic material, while the resilient layer is bonded to the external surface of the structural layer and is formed from a fiber-reinforced thermoplastic composite material. The resilient layer has an opening through which a metallic weight pad at least partially extends. The weight pad is bonded to the structural layer and includes an aperture for attaching a metallic weight. The golf club head can also have one or more structural members that are upright and connect the weight pad to the crown member.

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 mixed material golf club head including an outer metallic component and a polymeric component. The outer metallic component comprises the strike face. The polymeric component comprises a reaction wall that lies flush with a rear surface of the strike face. The reaction wall slidably translates across a back surface of the strike face at impact. In some embodiments, the outer metallic component is integrally formed with the crown and the polymeric component is integrally formed with the sole, to allow dynamic delofting for low-handicap golfers. In other embodiments, the outer metallic component is integrally formed with the sole and the polymeric component is integrally formed with the crown, to allow dynamic lofting for high-handicap golfers.

Golf club head including impact influencing flexture joint

A golf club head includes a rear body having a crown member coupled to a sole member, and a front body coupled to the rear body to define a substantially hollow structure. The front body includes a strike face and a surrounding frame that extends rearward from a perimeter of the strike face. At least a portion of an outer wall of the club head comprises a thermoplastic composite having a plurality of lamina layers. The plurality of lamina layers include at least a fabric reinforced thermoplastic composite layer and a filled thermoplastic layer, and the fabric reinforced thermoplastic composite layer and the filled thermoplastic layer are directly bonded to each other without an intermediate adhesive.

Embodiments of golf club heads with energy storage characteristics are presented herein. In some embodiments, a golf club head comprises a hollow body comprising a strikeface, a heel region, a toe region opposite the heel region, a sole, a top rail and an inflection point. The inflection point provides increase bending of the strikeface thereby providing performance enhancement over clubs without an inflection point.

Golf club heads with energy storage characteristics

Embodiments of golf club heads with energy storage characteristics are presented herein. In some embodiments, a golf club head comprises a body comprising a strikeface, a heel region, a toe region opposite the heel region, a sole, a crown, and an internal radius transition from the strikeface to at least one of the sole or the crown. In many embodiments, the internal radius transition region is not visible from an exterior of the golf club head and comprises a first tier, a second tier and a tier transition region between the first tier and the second tier.

A golf club head having localized heat treatment is described herein. Other embodiments are disclosed.

Golf club heads having a localized heat affected zone

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.
