Abstract
The leg support is constructed of a split plastic housing into which a tubular plastic foot is threaded. Metal sleeves of non-corrosive material are slidably mounted on each of the housing and foot to provide an aesthetic appearance. The internal thread on the housing is a buttress thread with a not quite perpendicular load receiving flank. The external buttress thread on the plastic foot has a mating upper flank. The leg support is able to withstand relatively heavy loads.
