Claim:
A receptacle for holding or transporting goods, materials, people, plants or animals, comprised of a self-leveling, balanced, independent receptacle suspended from a double-axis gimbal that is attached to a supporting framework, with a locking mechanism which allows the receptacle to be held in various positions, or unlocked, so that gravity will level the receptacle; a front and a rear of the receptacle having fittings to attach to a curved, notched receptacle plate which is placed beneath the receptacle and is part of the locking mechanism; the receptacle plate having a convex curvature which matches an arc defined by the movement of the receptacle as it swings forward and back on the gimbal and an edge having notches cut at radiating angles, at regular, closely spaced intervals; the receptacle plate being secured to a front and rear of the double-axis gimbal by two threaded bearings which are adjustable to regulate a swinging inertia of the receptacle; the gimbal being secured to the supporting framework by two threaded bearings which are adjustable to regulate the swinging inertia of the gimbal, the adjustable bearings being placed on raised arms located at the front, back and at each side of the gimbal; and the receptacle further including a curved frame plate having a concave curvature which matches the arc defined by the movement of the receptacle as it swings from side to side on the gimbal and an edge of the frame plate having notches cut at radiating angles, at regular, closely spaced intervals.
