  • Patent number: 5228661
    Abstract: A spare tire lift-and-carry apparatus for use on a vehicle includes a rotatable input shaft supported by a housing. A transmission mechanism is provided for transferring torque from the rotatable input shaft to a cable storage member driven in rotation about a longitudinal axis to retract and deploy a cable having a rim retainer connected at one end. The rim retainer is adapted to engage a spare tire or wheel assembly. A clutch mechanism can be provided for allowing transfer of rotation in both rotational directions from the input shaft to the cable storage mechanism, while preventing transfer of rotation through the clutch mechanism in either rotational direction originating from the cable storage mechanism, rather than the input shaft. A torque override mechanism can also be provided between the input shaft and the transmission mechanism.
