  • Patent number: 5816929
    Abstract: A new golf swing training device has a club with an elongated shaft with a hand grip at one end and a club head at the other end. A hinge is interposed between the first and second ends to allow the club head to break both rearwardly and forwardly. A spring biased projection cooperates with a recess so that different forces are required to break the club head in one direction, i.e., rearwardly, relative to a second force required to break the club in a second direction, i.e., forwardly. The tension of the hinge may also be adjusted. Access to the adjusting member is accessible from a location adjacent and non-aligned with the longitudinal axis of the club. In one embodiment, the hinge may be defined by a male/female assembly. In another embodiment, the hinge is defined by substantially identical side-by-side members.
