Escape device and use method thereof

An auxiliary escape method, comprising the steps of:

• mounting a rail member outside a building, wherein the rail member includes a plurality of sliding tracks which are sequentially connected to one another and each are tapered from top to bottom;
• putting a sliding unit into the rail member once the sliding unit is connected to an escaping person, wherein the sliding unit is configured to be pressed against by the sliding tracks of the rail member;
• and
• forcing the sliding unit to slip through the sliding tracks of the rail member by a body weight of the escaping person such that the sliding unit is sequentially pressed against by the sliding tracks and is slowed down due to a slide resistance generated between the sliding unit and each of the sliding tracks.

An escape device, comprising:

• a tube, extending along a longitudinal direction, wherein the tube is provided with an exit opening and a plurality of escape openings, the plurality of escape openings being intermittently arranged along the longitudinal direction;
• at least one pair of rail members oppositely mounted in the tube, wherein the pair of rail members constitute a sliding track, and wherein the sliding track has a relatively wide first end and a relatively narrow second end, the sliding track is tapered from the first end to the second end and is mounted on an inner surface of the tube via the first end, the second end of the sliding track faces the exit opening of the tube, and the first end of the sliding track is connected to a second end of an adjacent sliding track which is constituted by another pair of rail members;
• and
• at least one sliding unit, comprising a hanging member, wherein the sliding unit is adapted to slide on the sliding track and is configured to be pressed against and deformed by the sliding track.
