An escape chair or evacuation chair is a device manufactured for the smooth descent of stairways in the event of an emergency. The Evac Chair was invented in the United States in 1982. The single-user operation device does not require heavy lifting to evacuate a person. ==Types== The original Escape-Chair, with various models for various situations, addresses the need for an evacuation solution in case there is an emergency, and egress out of a structure or vessel becomes imperative. ''The table below is based on the Escape-Chair Standard and the Comfort model for comparison.'' ''These are based on an Evac Chair 300h Mk4 And an IBEX Transeat'' Enhanced models can have chairs that require two-person operation; however, these are more commonly used in ambulances. Lifting handles are used for descent and ascent of stairs. Caterpillar tracks are also used on the stairs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Escape chair」の詳細全文を読む スポンサード リンク
