PROBLEM TO BE SOLVED: To provide an evacuation elevator for evacuation to an upper floor of a building when tsunami occurs, which enables evacuation to an upper floor in an elevatable cage and prevents a counterweight located at the lowermost position from being washed away.SOLUTION: A cage 3 and a counterweight 4 are suspended with a rope 10 by making a pulley intervene so as to make elevation movements of them reverse to each other. The elevator comprises: a cage lifting mechanism 11 that elevates and lowers the cage; and an alone counterweight lifting mechanism that can pull up the counterweight alone without interlocking with the elevation movements of the cage. During evacuation to an upper floor of a building in the cage, by pulling up the counterweight located at the lowermost position, the counterweight is prevented from being washed away by a wave power of tsunami.
【課題】津波等の際に建物の上階へ避難するための避難用昇降機であり、昇降可能なカゴで上階に避難可能であるとともに、カゴを上階に停止させた際に最下位置にあるカウンタウエイトが津波等の波力で流されてしまうことを防止可能にする。【解決手段】カゴ3とカウンタウエイト4とを互いに逆の昇降動作をするように滑車を介在させてロープ10で吊る。カゴを昇降させるカゴ昇降機構11、カウンタウエイトをカゴの昇降動作と連動させずに単独で引き上げ可能なカウンタウエイト単独昇降機構を備えている。カゴで建物の上階へ避難して時、最下位置にあるカウンタウエイトを引き上げることで、カウンタウエイトが津波等の波力で流されてしまうことを防止できる。【選択図】図1
