Abstract: The invention provides a door system for a transit vehicle. It has an actuator which provides a rotary motion about an axis of the actuator for moving the door panel between an open position uncovering the aperture and a closed unlocked position covering the aperture. The actuator also provides a linear motion along the axis of the actuator for moving the door panel between the closed unlocked position and a closed locked position. The rotary motion followed by the axial motion is provided by a cylinder having a piston moved by fluid pressure. The piston includes a guide track in its exterior which engages rollers in the cylinder. The guide track has one portion curving around the piston and one portion parallel to the axis. The curving part provides the rotary motion and the straight part provides the axial motion. When the rotary motion is completed the piston encounters a stop on a shaft which supports the door. The actuator then moves the door axially to engage locks.

Abstract: An improved linkage mechanism for the opening and closing of a transom-type window, allowing for the window sash to fit tightly within the window frame in a closed position while, on the other hand, allowing for maximum open space for escape through the window frame when the window is opened. A tight fit between the sash and frame of the window is accomplished by having flanges on the sash and linkage means which causes the window sash to be first translated away from the window frame upon opening, providing enough clearance for the window to then be pivoted to an open position on a pivotal axis disposed away from the frame. The linkage is also designed to allow for maximum open space for individuals to escape through the window frame in an open position and a latch mechanism for holding the window in the full-open position for escape.
