The present invention relates to an integrated folding safety handrail and outdoor escape stairs for high-rise buildings and an emergency escape device which are applied to high-rise buildings such as safety handrails for preventing falling from a movable passage exposed to apartment houses such as apartments or office buildings, and the outside and is applied as a substitute for safety handrails in high-rise buildings or outdoor ground clearance 3 m or more which is usually used as a safety handrail for falling prevention and so that an escaping person in the high-rise building escapes outside or safely escapes to a lower floor in case of emergency such as fire, terror, and disaster. Particularly, the present invention relates to an integrated folding safety handrail and outdoor escape stairs for high-rise buildings and an emergency escape device, including a fence unit 1 in which an entrance unit 10 and a safety fence unit 20 are integrated; and a sliding stair unit 30 formed at a lower end of the fence unit 1.

A ladder unit is slidably joined to an edge of or beneath a working surface by a mounting frame having a roller assembly or other slidable means. The ladder unit includes a stair assembly that is rotatably mounted to the mounting frame by a hinge, and configured to rotate between an open position, in which a support provided on the stair assembly does not contact the working surface, and a closed position, in which the support contacts the working surface. In this regard, the ladder unit may be slidably moved from location to location along the working surface when the stair assembly is in the open position with substantially low friction, and may be stabilized in a location for use when the stair assembly is in the closed position.

A ladder supporting device for supporting a ladder in upright orientation at an upright surface comprises a channel extending longitudinally from a first end to a second end arranged horizontally spaced across the upright surface with a backside facing the upright surface, a holding device located outside the channel distal to the upright surface, and at least one wheel rotatably supported on an axle connected to the holding device and passing into the channel which receives the at least one wheel such that the holding device is positionable longitudinally of the channel by rolling movement of the at least one wheel along the channel.
