Abstract: The collapsible armless chair comprises a pivotally connected seat frame and a back frame which also define the leg supports. An arcuate-shaped projecting portion at the bottom of the back frame provides stability for the chair. The projecting portion is also angled upwardly relative to the ground plane. The user may lean back in the chair until the front leg support leaves the ground and rotate the chair right or left without rising from the chair.

Abstract: A carriage for descending stairs carrying a person under the control of an operator, i.e., an able-bodied person walking behind the carriage. The person in the carriage rests upon a seat with an upright back. The carriage is supported at its sides upon two support units each of which has an endless belt which extends along a rigid longitudinal frame with two pulleys mounted upon horizontal axes at the opposite ends of the frame, and with belts extending around those pulleys and forming two longitudinal runs between the pulleys. Each belt is formed by a continuous strip of heavy fabric with a continuous strip of flexible rubber bonded to the fabric. The belts of the support units act as brakes to retard the movement down the stairs.

Abstract: A folding chair and cart structure having an upright frame and a transverse member pivoted thereto, one end of the transverse frame forming a seat portion and the other end extending beyond the upright frame and carrying a pair of wheels, a sheet of canvas secured to the upright and transverse frames to form a seat and a track for removable engagement with the wheels. The structure functions as a cart by merely tilting the upright frame to a horizontal position and the entire structure is foldable into a compact unit for transport and storage.
