  • Patent number: 5993133
    Abstract: An apparatus designed to carry a spare tire against the underside of a vehicle, rearwardly thereof, featuring a mounting plate, for the tire assembly, attached to the first end of a cantilever arm. The second end of the cantilever arm is pivotally attached to a carrier base frame, which in turn is pivotally suspended from support members attached to the vehicle's frame, by four suspension bars. Movement of the base frame is controlled by operation of a driver tube incorporated into the base frame, comprised of a rectangular tube, inside of which are a drive screw, and a rectangular nut. Two cables attached to the nut are directed by pulleys to the center of the back transverse member of the frame, then right and left to the two back corners, thense to a point on each longitudinal member of the frame, then vertically to anchor points on the support members attached to the vehicle's frame. Clockwise rotation of the screw pulls cable into the tube, moving the base frame forward and upward into storage position.
