Abstract:
1. A powered convertible walker/wheelchair/transporter aid useable selectively as a walker, wheel chair or a transporter for traversing a support surface, comprising: a generally rectangular wheel-base frame, including forward and rearward leg sections attached generally at the lower region thereof, and extending generally parallel to the support surface, said leg sections having a weight-bearing caster disposed on the underside thereof, whereby said forward and rearward leg sections form a rollable frame for said transporter; and an upper frame mounted on said base frame, including a pair of transporter vertical supports, each selectively carrying longitudinal supporting arms disposed in generally parallel relation at the upper ends thereof, and each supporting arm removeably secured to a first end of each supporting arm by a lateral gripping handle whereby said arms and handle form a generally U-shaped upper frame with said vertical supports; and each of said vertical supports has disposed at its lower ends, generally adjacent said leg sections a sleeved coupling attached to said base frame, and including a drive wheel, wherein said coupling has therein a spring biasing unit to position said vertical supports and drive wheel upwardly and free of said support surface when said vertical supports are unloaded and said drive wheel and vertical supports are moveable downwardly to contact said support surface in a driving condition, as upon loading said vertical support beyond the spring bias in said sleeve coupling, whereby said transporter functions as a free-wheeling walker in the unloaded condition and as a driven wheelchair/transporter when in a loaded condition.
