A door apparatus for closing an access opening and to a parking apparatus equipped therewith. The door apparatus has two vertically aligned guide rails and an inner and an outer door element which are each movably mounted in/on a vertically aligned inner or outer guide of the guide rails. In a closed position, the inner door element is arranged in a first region of the access opening which is situated lower than a second region in which the outer door element is arranged. In an open position, the inner and the outer door element are arranged in a third region of the access opening which is situated higher than the first and the second region. Furthermore, the door apparatus has a locking element and a coupling element.

A window arrangement for a rail vehicle includes a window pane disposed in a movable sliding frame and having at least one open position, a closed position and a transport position. The movable sliding frame is disposed in a window guiding frame, and the window pane has a larger surface than a corresponding window opening of the window guiding frame.

A remote controlled recessed window. The remote controlled recessed window includes a channel disposed within a wall, wherein a pair of opposing tracks are disposed within the channel. A pane having a first side and a second side is disposed within a frame. The first side and the second side are slidably engaged with the pair of opposing tracks. A motor is disposed within the channel and is operably connected to the pane such that the motor can slide the pane along the pair of opposing tracks between an open position and a closed position. A wireless receiver is in electrical communication with the motor. A wireless device can communicate with the wireless receiver to actuate the motor.

A steam sterilizer having a door movable relative to an opening between a first open position and a second closed position. A plurality of spaced-apart roller assemblies are aligned along edges of the door to align the door relative to the opening as the door moves between the open and closed position. Each of the roller assemblies are comprised of a cylindrical roller having an outer annual recess extending along the periphery thereof. The recess is dimensioned to receive a lateral edge of the door. The roller is mounted on a shaft and is movable against a biasing force axially along the axis of the shaft.

The invention is directed to a vertical sliding window as a closure for an opening in an exterior wall of a building, wherein for opening, at least one window pane of the sliding window may be lowered downwardly, in particular into a flat chamber within a box. The sliding window may be provided as a finished module, with the option of integrating insulation and/or designing the facade; it is also possible to integrate a roller shutter box, in particular also in heat-insulated form. The area of application for such a sliding window component ranges from single-family dwellings to high-rise buildings of any conceivable height.

A window assembly for use in a vehicle that includes a window frame including a first end and a second end opposite the first end, a first frictional slide track, a second frictional slide track, an opaque shade selectively movable within the first frictional slide track, and a transparent shade selectively movable within the second frictional slide track. The first frictional slide track and the second frictional slide track are positioned such that the opaque shade and the transparent shade are both selectively retractable within, and selectively extendable from, the first end of the window frame.
