ABSTRACT:
A mobile support device for a handicapped person and rollable on a reaction surface, the mobile support device comprises first and second longitudinally extending frame sections oriented in spaced relationship. A back support portion extends transversely between and is coupled with the first and second frame sections. A seat portion extends transversely between and is secured to the first and second frame sections. A wheel assembly is mounted on the frame sections so as to engage the reaction surface. The wheel assembly includes a pair of front caster wheels, a pair of rear caster wheels and a pair of central wheels. Each of the central wheels has a fixed transverse axis of rotation and is positioned intermediate the front and rear caster wheels to inhibit transverse motion. Each of the frame section carries one of the front caster wheels, one of the central wheels and one of the rear caster wheels. Each of the wheels has a lowermost tangent lying in a common plane. The wheel assembly constitutes means to inhibit rocking of the mobile support device about the central wheels so that contact between all of the wheels with the reaction surface is maintained. The frame sections are arranged so that unrestricted access is provided for the handicapped person to the seat portion and the back support portion. The frame sections, the seat portion and the back support portion are further arranged to permit the feet of the handicapped person to reach the reaction surface to propel the mobility support device. The mobility support device further comprises a braking means for braking at least one wheel on each of the frame sections.
