RESCUE ELEVATOR SYSTEM Russian patent published in 2019 - IPC E06C5/04 E06C7/12 

FIELD: life-saving methods and devices.

SUBSTANCE: emergency rescue lifting system (10) comprises emergency ladder (12) and elevator (14) moving along rails (24, 26) on upper side of emergency ladder (12) in end position at one end (16) emergency ladder (12), and elevator drive, containing rope (48), cable winch for tensioning rope (48) and deflecting roller (64), through which rope (48) is directed from cable winch to suspension point (46) on elevator (14), wherein deflecting roller (64) is located under rails (24, 26) on or near one end (16) of emergency ladder (12). According to the invention, suspension point (46) is shifted towards rear end (68) of elevator (14), which is retracted from one end (16) of emergency ladder (12) so, that in suspension end position (14) suspension point (46) was located at some distance from deflecting roller (64) in direction of rails (24, 26) continuation, and elevator (14) comprises ladder (36) for passage to overlap distance between suspension point and deflecting roller in end position of elevator (14), wherein said ladder (36) is located over rope (48) and is installed between rails (24, 26) on hinged axis (47) perpendicular to rail continuation direction (24, 26) and extends normally towards one end (16) of emergency ladder (12) so as to be able to turn between a flat position, in which it is generally parallel to rails (24, 26) plane, and an inclined position, in which it is inclined downwards in the direction of the lower side of emergency ladder (12).

EFFECT: object of the present invention to provide a rescue elevator system of the above kind with an improved force transmission of the elevator drive from the rope winch to the suspension point at the elevator.
