Abstract:
A golf club having a hollow shaft whose flexibility is determined by the tension on a wire coinciding with the shaft longitudinal axis. In a first mode the wire is attached between a longitudinally movable assembly in a rotatable handle and a fixed assembly at the shaft lower end. The movable assembly includes outer and inner tension tuner members, a collar, a clamp and bifurcated collet, and outer and inner twist-prevention housings. In second and third modes, the wire is attached between a fixed assembly in a non-rotatable handle and a fixed assembly at the shaft lower end. The upper assembly includes a cap member, a wire-end clamping member, and a tension support member. The second mode uses a thin round wire; the third mode uses a thin tape-shaped wire.
