    Abstract: A power door operator for transit vehicles utilizing a rodless pneumatic cylinder as a prime mover in opening and closing doors in the sidewall of a transit vehicles. Door movement having a controlled, predetermined door edge force is achieved through mechanical coupling an external piston of the rodless cylinder and vehicle doors through an endless toothed belt. Magnetic coupling between internal and external pistons of the cylinder provide controlled force having a maximum or breakaway value applied to the operated door. A novel reaction lock operated by admission of pressurized air to the cylinder latches or unlatches the operated door in its closed position subsequent or prior to door closing or opening. Control of door motion at the ends of its travel is achieved through the use of a novel differential area internal piston in the pneumatic cylinder. Available internal piston force is modified for predetermined piston positions on approaching either end of the cylinder through the use of a sliding rod contained by the pressure sensitive internal position. Movement of the sliding rod adjust the effective piston area so as to modify available force to controlling door motion.

    Abstract: Concentric tubes, mounted for relative rotation about their common axis, each include radially extending hinge plates. The tubes carry contra-rotational cam slots through which project the ends of a cross-shaft. Bearings on the ends of the cross-shaft engage the milled cam slots. A cylindrical cross roller bearing block mounting the cross-shaft is axially, slidably positioned within the inner tube and is under a biasing force exerted by a compression spring abutting one end of the block. The cam profiles of the slots includes portions at the ends of the slots extending parallel to the rotational axis to lock the inner and outer tubes together at the beginning and end of the stroke with the cam profile controlling the hinge plate acceleration, deceleration, and velocity, in addition to ensuring positive locking of the hinge in plate open and closed position.

    Abstract: A sliding door structure suitable for furniture and the like, comprises a first door (1) and a second door (2), respectively slidable on a pair of parallel, spaced upper guides (4,6) and a pair of parallel, spaced lower guides (3,5). The said first door (1) is connected to rollers (17), which roll on the guides (4), by a mechanism (10-40) able to cause a coplanar positioning of the doors (1,2) in the closure position, and displacement of the first door (1), substantially perpendicularly with respect to the door translation direction, to superimpose the first door (1) over the second door (2) during opening of the doors themselves.
