ABSTRACT:
The escape of the present invention is installed in each storey of a building and comprises a storage space for the escape, a sliding platform, and an escape passageway. The storage space is formed in each storey of the building to have a configuration of a rectangular parallelepiped. The storage space has an opening in an external wall of a building. The platform is normally put away in the storage space and, in case of emergency, slides out from the opening of the storage space to form a landing of the escape passageway. The escape passageway is put up in the platform while one end of the passageway is pivotally attached to the platform to rotate the passageway downwards. When the escape is used, one end of the escape passageway rotates toward a lower platform to form an inclined passage between the upper and lower platforms.
