Abstract:

Golf club heads are releasably engaged with shafts so that the club heads and shafts can be readily interchanged and/or so that the shaft position with respect to the club head can be readily changed. Assemblies for connecting the club head and shaft may include: (a) a first cylindrical structure having a cylindrical interior chamber for receiving a golf club shaft, a first rotation-inhibiting structure, and a securing structure; (b) a second cylindrical structure having a borehole for receiving the first cylindrical structure, and a second rotation-inhibiting structure that engages the first rotation-inhibiting structure and (c) a securing system for releasably engaging the securing structure. The shaft may extend at an angle from the shaft connection assembly so as to allow adjustment of the shaft position with respect to the club head by rotating the first cylindrical structure or exchanging the second cylindrical structure.
