ABSTRACT:
A riding emergency or fire escape apparatus mountable interior of a building for delivering an inhabitant exterior of the building for free fall descent to the ground. The apparatus of this invention exterior of the building essentially comprises plate members mounted in a recess provided in the wall of the building or spaced from the wall of the building a few inches so as not to detract from the architecture of the building. A base plate is provided with a vertically extending zig-zag track. A cover plate overlaying and planularly spaced from the base plate is formed with a vertically extending lineal track. The passenger transport mechanism is provided with a chair and is mountable interior of the building. Similarly arranged base and cover plates containing zig-zag tracks and lineal tracks respectively, are provided at each floor level interior of the building. The tracks of the respective plates align with the corresponding tracks in the fire escape structure exterior of the building through an openable door at each floor level. The passenger transport mechanisms stored at each floor level, comprise a chair connected to a vertically disposed roller trolley frame which is provided with rollers which ride the zig-zag track for a slowed down free fall descent while a second roller rides in the vertical track so that the passenger chair is restrained to a lineal vertical descent.
