Abstract
The tire lift mechanism has a cable and a drive tube which includes an outer tube portion and an inner tube portion. The outer tube portion is telescopically mounted upon the inner tube portion. The drive tube is adapted to be selectively rotated to cause the cable to be raised and lowered thereby raising or lowering the spare tire. The lift mechanism also includes a driven shaft having an axis of rotation and structure for raising and lowering the cable. The driven shaft is selectively driven by the drive tube through a pivot coupling interposed therebetween. The pivot coupling has a pair of inner and outer tubular coupling members. The inner coupling member has an axially extending bore for receiving the axially extending driven shaft. The inner coupling member and the driven shaft extend into the interior of the inner tube portion. The outer coupling member is mounted on the exterior of the inner tube portion. Radially extending aligned openings are provided in the inner and outer coupling members, the inner tube portion and in the driven shaft. A radially extending connecting pin is mounted in the aligned openings for pivotally connecting the coupling members and the inner tube portion to the driven shaft. The driven tube and the driven shaft are operatively connected through the coupling members and pin such that the axis of rotation of the driven tube is non-parallel to the axis of rotation of the driven shaft.
