ABSTRACT:
A doorway type opening is formed through the outside wall of a building. A door device is hingedly affixed to the building at the lower edge of the opening and has a plurality of telescoping sections juxtaposed when the door device is closed and forming an extended planar incline when the door device is opened. Thus, the door device when open supports people leaving the building via the opening and functions as a slide to conduct them to the ground. A door control device affixed to the door device and the building lowers one end of the door device to the ground supporting the door device in its extended open condition from the lower edge of the opening to the ground and supports the door device in its closed condition as a door openable only from inside the building.
