  • Golf club heads with golf coupling mechanisms
    Patent number: 11554296
    Abstract: 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.
