摘要： Emergency stairs are designed to be mounted externally on buildings and are provided with platforms at each floor as well as ladders/staircases between the platforms. Platforms are hinged to the house wall and are at their extreme edges connected by the air of mutually articulated connecting means. The ladders/staircases are suspended from the underside of the platforms in articulated members under openings in the platforms and with the rungs of the ladder arranged in parallel with the house wall. The ladders are at their lower ends slidably supported by the next lower platform. In a position of non-use platforms and ladders are retracted into contact with the house wall and may be actuated by an actuating mechanism which may be operated from each floor.
