ABSTRACT:
A system consisting of a door closure and door hanger which are integrated to achieve improved operation and simple construction and particularly characterized by a single action pneumatic cylinder and an internal return spring coiled around the piston rod to achieve pneumatic opening of the sliding doors and spring closing of the latter respectively in combination with novel track units featuring removing the load on the balls when the doors are in closed position and shorter track units less subject to longitudinal deflection of the passenger vehicle. The return spring is taken advantage of to produce unhurting impact and closure force at the end of the closing course and to eliminate the sealing requirements around the piston rod at the corresponding end of the pneumatic cylinder. The slide track units include a pair of movable door carrier track members to which are attached the doors respectively, the piston rod, and an interconnecting cable allowing removal of the doors without disturbing the setting or mounting of the door closure and hanger system.
