  • Patent number: 4687068
    Abstract: To enable an invalid's wheelchair to negotiate stairways, it has a chassis frame equipped with ordinary motor-driven road wheels for level running and a pair of crawler belts for stair ascent or descent. Either the wheels or the belts may be selected, either to the exclusion of the other, as the mode of travel. A chair or like load carrier is movably mounted on the frame, and linkage is provided so the center of gravity of the load is adjusted to give the required stability for the selected travel mode.
