Abstract
The present invention relates to an escape device, involving a tube, a rail member, and a sliding unit. The tube, extending along a longitudinal direction, is provided with an exit end and intermittently with a plurality of escape openings. The rail member includes a plurality of sliding tracks sequentially connected to one another, wherein the neighboring sliding tracks are connected to each other by associating a relatively wide first end with a relatively narrow second end, the second end facing the exit end of the tube. The sliding unit comprises a deformable member which is adapted to slide on the rail member and configured to be pressed against by the second ends of the sliding tracks such that a slide resistance is generated to reduce sliding velocity. Therefore, the effects for the reduction of descending velocity as well as rapid and safe escape are achieved.
