摘要： Apparatus for railway cars to handle the ingress and egress of passengers through a door opening where the apparatus selectively provides at the exterior of the car at the door opening an adjustable height platform, steps or a ground-to-car floor platform lift. The apparatus is storable within the railway car and extendable exteriorly of the railway car where it can then be selectively conditioned for a desired passenger handling mode as a platform positioned at a desired height between the car floor and ground, a series of steps extending between the car floor and ground, or a platform lift movable between ground level and car floor level.

摘要： 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.
