Claim Text:
1. An escape device, comprising: a rail member, extending along a longitudinal direction, wherein the rail member includes a plurality of sliding tracks sequentially connected to one another along the longitudinal direction, each of the sliding tracks having a first end defining an opening wider than an opening at a longitudinally opposed second end, an intermediate portion extending between the longitudinally opposed first and second ends, the intermediate portion having laterally opposed sloped wall surfaces defining a tapered profile, wherein sequentially disposed pairs of the sliding tracks are connected with the second end of one connected to the first end of the other; and a sliding unit including at least one deformable member and a hanging member extending therefrom, wherein the deformable member slides on the rail member and is slidably captured between the sloped wall surfaces, and when the deformable member slides from the first end to the second ends of each sliding tracks in response to gravity, the deformable member is pressed against and deformed by the sloped wall surfaces to generate a slide resistance therebetween to reduced sliding velocity of the sliding unit.
