NON-POWERED ESCAPE DEVICE DESCENDING AT CONSTANT VELOCITY

摘要

The present invention relates to a non-powered escape device descending at a constant velocity, which can be operated without power and enables residents on all floors to safely and rapidly escape. The non-powered escape device descending at the constant velocity includes: a guide rail (10) fixed to an outer wall (1) of a building adjacent to a veranda of the building by being erected from an uppermost floor to a first floor; multiple leaf springs installed from the upper part to the lower part in a hollow unit (11) of the guide rail (10) at fixed intervals; and a constant velocity descending unit (30). The constant velocity descending unit (30) comprises: a first roller (31) inserted into a roller insertion unit (12) of a guide rail (10) and coming into contact with the upper part at the other end of the leaf spring (20), wherein the first roller is in contact with the inner side of an outer surface (10c) of the guide rail (10); a second roller (32) coming into contact with the outer side of the outer surface (10c) of the guide rail (10); a roller connection link (33) connecting the shaft of the first roller (31) and the shaft of the second roller (32) as each end is connected to the shaft of the first roller (31) and the shaft of the second roller (32); and a belt connection unit (34) including a belt connection ring (34a) and connected to the shaft of the second roller (32) by a hinge. The first roller (31) elastically transforms the other side end of the each leaf spring (20) in order by the weight of a passenger, so the constant velocity descending unit descends at a uniform velocity by widening a gap between the other end of the leaf spring (20) and the inner side of the outer surface (10c) of the guide rail (10).;COPYRIGHT KIPO 2016
