Abstract: A spare tire carrier lock including a split body collectively formed of at least two body sections, wherein the exterior shape of the split body is complementary to the shape of a predetermined socket of a hoist shaft of a hoist assembly for a spare tire carrier so as to be drivably received into the socket. The body sections are resiliently conjoined to form the split body via at least one, preferably two, resilient members. The split body has a first end at which a tapered seat is formed. A body shaft runs from the seat to a second end of the split body. A tapered armature is shaped to be seatably received by the seat and is provided with a threaded bore for being aligned with the body shaft. A head is located at the second end of the split body having a diameter which prevents its being received into the socket. A head shaft is provided in the head for being aligned with the body shaft, wherein opposite the split body, the head shaft is enlarged to form a recess.

Abstract: A rehabilitation device for conditioning the lower extremity joints of a user includes a platform having an upper surface with spaced apart enhanced friction regions for stabilizing the users feet on a variety of side to side locations on the platform whereby tipping movements about a pivot plate connected to the platform will produce a closed chain kinetic exercising of such joints.
