Abstract: A vehicle step apparatus including a first extending and retracting device having a first mounting bracket, a first step bracket, and a first arm assembly configured to drive the first step bracket to move between a first extending position and a first retracting position; a second extending and retracting device comprising a second mounting bracket, a second step bracket, and a second arm assembly configured to drive the second step bracket to move between a second extending position and a second retracting position; a step mounted on the first and second step bracket; a first permanent magnet direct current motor mounted on the first mounting bracket and coupled with the first arm assembly to drive the first arm assembly; and a second permanent magnet direct current motor mounted on the second mounting bracket and coupled with the second arm assembly to drive the second arm assembly.

Abstract: A step drive for a movable step, the step drive being arranged below a swinging-sliding door. The step drive includes an opening-out mechanism located in a lower region of a secondary closing edge of the swinging-sliding door. The opening-out mechanism is connected to and actuated by a door drive and the opening-out mechanism interacts with the movable step.

Abstract: An improved door assembly has a single movable door and may have a separate movable high platform threshold. The door assembly is formed of an upper door section and a lower door section which is fixed to the upper door section. A support member may be integral with or slidably engaged with the door assembly, disposed as an angle iron fixed to the door assembly, or disposed on the side of a stairwell of a rail passenger car.

Abstract: A portal system for a railway or other vehicle having steps from the interior flooring downwards to the ground has a bridge platform to be deployed for use when the vehicle is stopped at a railway station platform. A threshold member closes at least part of the gap that typically lies between the bridge platform and the railway station platform. A carrier mechanism supports the threshold member on the outer side of the door and deploys the threshold member adjacent to the bridge platform when the bridge platform is also deployed and the door is open, and not otherwise. The carrier mechanism comprises a rail mounted on the threshold mechanism, and at least two slides mounted on the outer side of the do or and that slide with respect to the rail as the door slides between open and shut positions.

Abstract: The invention relates to a door for a railway vehicle, intended for a door opening having steps, on which there are provided a platform and a threshold above the steps to permit disembarking onto a railway platform situated higher than the steps. The invention is characterised in that the door includes a single leaf and a mechanism provided for controlling the unlocking of the threshold member with respect to the door, when the platform is in the position of use and the door opens, so that this threshold member remains in place opposite the edge of the platform in the position of use and the edge of the railway platform.

Abstract: A door system for a railway car which provides for both high and low level access. The door system comprises a sliding door, a platform displaceable between raised and lowered positions for respectively clearing and covering the stairwell of the railway car, and a threshold extending laterally outwardly of the sliding door to provide a continuation of the platform when displaced to its lowered position. The threshold is releasably connected to the sliding door for co-linear movement with the sliding door when the platform is raised, while remaining stationary in a functional position when the platform is lowered for enabling high level boarding.

Abstract: A handrail assembly for access walkways on railway hopper cars is movable between a retracted position, where the assembly is stored for transit, and an extended position where the posts and rails of the assembly are raised to provide a protective barrier. The posts and rails are pivotally interconnected to provide a parallel linkage, each of the posts swinging about an axis that is displaced from a right angle to the longitudinal axis of the walkway. Also, the posts are inclined from the vertical when the assembly is in its extended position. The combined effect of the displacement and the inclination maintains the components of the assembly within allowable clearances and precludes interference with the top surface of the car body. A counterweight arrangement allows the posts and rails to be easily raised manually from one end of the car, and a mechanical lock is provided to positively retain the assembly in either its extended or retracted position.

Abstract: Upper and lower sectional doors of rectangular configuration are mounted within an aircraft fuselage door frame and hinged for pivoting about horizontal axes at the upper and lower horizontal edges of respective door sections. A step is mounted to the interior of the lower door for pivoting along one horizontal edge about a horizontal axis between a first position with the step flush with the door interior and a second position projecting generally at right angles thereto. A plurality of laterally slidable latch pins fixed to the lower door section along vertical side edges are projectable into holes within the fuselage doorframe through a linkage system coupled to a shaft pivotably mounting the step to the door. The latch pins are projected to latching position when the step is folded flush to the door and retracted to unlatched position by manual movement of the step to its projected position prior to opening the lower door.
