【発明の属する技術分野】
この発明は火災時にエレベータを避難用に利用する場合に用いられるエレベータの非常用運転装置に関するものである。
【０００２】
【従来の技術】
火災時には、停電になる可能性が大きく、自家発電源、バッテリーを設置してエレベータを避難に活用することが考えられる。この非常用エレベータは、火災が発生すると保安上等の理由で常用の電源が遮断されることがあるので、非常用エレベータの電源として、予備電源を備えることを義務付けている。この予備電源は一般にエンジン駆動の交流発電機が使用されるが、その容量は全非常用エレベータが全負荷上昇運転するときに必要とする電力を６０分間以上連続して供給できるものであることが要求される（非特許文献１）。また、従来のエレベータの運転方式において、停電が発生すると、自家発電源がエレベータに給電された時、乗客の総重量が定格積載量によって決定されるつり合いおもりに対比して重いか、軽いかを検出し、重い場合は下方基準階に、軽い場合は上方基準階に向けてかごを走行させるもの（例えば、特許文献１参照）、或いは非常時に停止したエレベータの電磁ブレーキを開放し、かごとつり合いおもりとの不平衡により、かごを上下動させ、最寄階に停止させるエレベータの非常救出運転装置がある（例えば、特許文献２参照）。
