  • Patent number: 6808047
    Abstract: An escape device for allowing a person to escape from a high position to a predetermined landing point. The escape device basically includes: an elastic cord element elastically stretchable to a maximum length substantially at the landing point; a container element provided at the high position; and a carrier element connected with the elastic cord element. Accordingly, a person can descend via the carrier element from the high position and softly land on the landing point. A plurality of carrier elements may be provided and connected together via plural elastic cord elements and auxiliary ropes, using disengagement mechanism, to provide a multistage escape device, so that the carrier elements can be disengaged from one another in sequence when they are falling so as to permit person(s) to descend and softly land on a ground at the landing point.
