FIRE AND EMERGENCY-EXIT DOOR HAVING A PRESSURE-EQUALIZATION FUNCTION AND PROTECTION AGAINST BLOCKAGE

摘要

The invention relates to a new door having at least one door wing, which is formed by two door leaves that can be pivoted in relation to each other, between two rooms having different values of the air pressure present therein. The room (8') forming a hazard to persons, e.g., in the event of a fire, has a lower air pressure (p1), and the escape and evacuation room (8) has a higher air pressure (p2). In order to ensure that the door (100) can be opened without hindrance in the event of a rush to the door wing (1) of persons escaping from the hazard zone having lower pressure (p1) into the escape room having higher pressure (p2), at least one protecting and door-wing-motion-sequence-guiding device (5 or 5, 5') is provided, which protects a pivoting wing part of the door wing against blockage of the opening process by the fleeing persons at the start of the opening swing-out and each of which is formed by means of a cage, which has at least two partial cage walls articulated to each other by means of vertical axes.
