ABSTRACT:
This invention provides a multifloor type escape bridge apparatus for use in a multistory building in emergency situation, such as a fire or the like. In a normal situation, the necessary members for example expanders, floor boards, suspension ropes and up and down winding mechanisms are set up between adjacent buildings in a contracted condition under a supporting body. In the case of an emergency, the expanders fixed at the supporting body are extended downwardly so as to set up at each floor a board which provides connections between corresponding openings at opposed walls of said adjacent buildings. This enables individuals to escape from one building to another.
