Abstract

A landing apparatus for escaping from high-rise buildings is a self-help apparatus which is suitable for a person who needs to urgently evacuate and escape from a window, a balcony or other space passages on the occasion of living or working, learning, entertaining, shopping in a market in buildings of which the heights are more than two meters when a calamity happens suddenly. A flat band which is knitted from polyester yarns with high strength is tightly wound in a circular disk in an oblate stainless steel shell body. An end head of the flat band is connected with a safety hook after passing round a pinch wheel, a friction wheel, a roller and a friction wheel, and is reliably hung on a fixed hanging ring. The safety hook which is arranged under the shell body is hooked on a chest band of the escaping person. The landing apparatus for escaping from high-rise buildings has a technical problem that the gravity of the own weight, the torsional force of a torsional spring, and the acting force of lead angles of curved grooves of eccentric circular arcs arranged on hand wheels on both sides are respectively concentrated and sent to the roller by the escaping person through the flat band, and are pressurized on contact surfaces between the flat band and the friction wheels. At the same time, the flat band is also pushed and pressed on the friction wheels by the torsional force of the torsional spring via the pinch wheel. Therefore, enough frictional force is generated between the flat band and the friction wheels, and the escaping person and the landing apparatus for escaping from high-rise buildings together fall onto the ground slowly.
