  • Patent number: 4193147
    Abstract: A cantilevered lifting and transporting device which may be automatically or manually converted from a chair to a stretcher or vice versa. The lifting and transporting device is comprised of a U-shaped base having a pair of vertical telescoping supports on which a horizontal frame is mounted. The frame has two horizontal members or rods acting as fulcrums for supporting a rotatable back rest and leg rest which also provide support for a seat. The device is raised and lowered by a hand-cranked screw and nut combination in one of the vertical supports. An articulated connection between the rotatable back rest and the rotatable leg rest permits rotation of these parts from substantially vertical positions to horizontal positions. Attached to the rotatable back rest is an indexing plate which has a plurality of holes cooperating with a spring-biased plunger to lock the device in a variety of positions from upright to flat or in between.
