substantially uniform dimension throughout its length for
utilization through an access opening in a bumper, a locking
shaft edge formed by the convergence of two planar surfaces
insertable into the distal end of a hoist shaft for rotational
interlock therewith, and a lock which affords limited arcuate
displacement of the locking shaft due to rotational
interference with an overhanging bumper lip.
Heathcoat, which also discloses a spare tire security
device, offers no cure for the foregoing deficiencies in

unauthorized access thereto.
