ABSTRACT:
A simplified wheel-lift mechanism is disclosed. The components of the wheel-lift mechanism are all formed of a plastic material that is corrosion resistant. Further, the wheel-lift mechanism includes a one-piece flexible coupling which reduces the complexity of the system over prior art systems. The one-piece flexible coupling includes a plurality of integrally molded discs connected by a plurality of circumferentially-spaced integrally molded posts. This results in a strong coupling which allows relative angular motion between the ends of the coupling. In a further feature of this invention, a locking key is operable to lock the wheel hub at a particular location. The locking key is selectively released to allow the wheel to be lowered. A unique drive mechanism is also included.
