A single powered dual movement motion device preferably mounted on the distal end of a boom and connected to a platform adapted to carry a wheel chair of a handicapped person. The motion device has a base frame that mounts it on the boom. A first extension frame is pivotally connected to the base frame and a second extension frame is hingedly connected to the first extension frame. A reversible rotatable drive assembly is fixed to the base frame and is driven by a reversible power source. The reversible rotatable drive assembly includes a release and lock means whereby an arcuate path will be given to an extremity of the second extension frame in the release mode and a straight forward path in the locked mode. A reversal of the power source will reverse the sequence of events.
A dual movement single powered motion device comprising a base frame, a first extension frame pivotally connected to said base frame, a second extension frame hingedly connected to said first extension frame, a rotatable power source fixed to said base frame, a rotatable drive assembly mounted on said base frame and driven by said rotatable power source, said rotatably drive assembly including a driven shaft clamped to said first extension frame for pivotal movement thereof, and including a release and lock means, a tie-rod connecting said release and lock means to said second extension frame whereby upon rotation of said rotatable power source, the rotatable drive assembly will produce an arcuate path to an extremity of said second extension frame in the released mode and a straight forward path in the locked mode.
A dual movement single powered motion device as claimed in claim 6 wherein the drive roller slots are tapered to assist in the rollers up and down movement to the released or locked position.
