发明名称 Emergency escape device
摘要 An emergency escape device includes a rectangular carrier in which a rope-ladder is stored. The carrier includes upper and lower horizontal beams, and two vertical side beams interconnecting the upper and lower horizontal beam. Each of the vertical side beams has a retaining member to retain spacers that are fixed to two ends of the rungs which, in turn, interconnect two parallel cables so as to define the rope-ladder.
