Abstract
A wheelchair arrangement in which the side frames which are supported by the wheels are provided with sockets for the reception of arm assemblies having elements formed to be inserted in the side frame sockets for easy removal. In that arrangement, the sockets are held in spaced relation at a fixed dimension, the sockets are formed so that one socket has a major dimension greater than any dimension of the other socket, and the elements on the arm assemblies are spaced apart and sized to fit into the sockets to be substantially free of sideways wobble, with one socket having its major dimension oriented to allow reception of one element and accommodate tolerances in the spacing of the elements on the arm assemblies.
