To provide a smoke shielding device for an elevator at a lower cost capable of suppressing the movement of smoke through a hoistway when a fire occurs.SOLUTION: A smoke shielding device for an elevator is retractably mounted on at least one exterior surface of an elevator car that ascends and descends in a hoistway, extends, when deployed, between the elevator car and the hoistway over all exterior surfaces of the elevator car facing the hoistway, and includes a first smoke shielding member that vertically partitions the space in the hoistway, and first deploying means that deploys the first smoke shielding member. Further, the smoke shielding device for an elevator may include: a second smoke shielding member mounted in a retracted state to the outer surface of the side of the elevator car on which the doorway is provided, extends, when deployed, between the elevator car and the hoistway over the entire circumference of the doorway while dividing the space in the hoistway into the space between the doorway and the hoistway and other spaces; and second deployment means for deploying the second smoke shielding member.SELECTED DRAWING: Figure 4
【課題】より低コストで、火災が発生したときに昇降路を経由した煙の移動を抑制できるエレベータ用遮煙装置を提供する。【解決手段】昇降路内を昇降するエレベータかごの少なくとも1つの外側面に格納状態で取り付けられ、展開されたときに、エレベータかごの昇降路と対向する全ての外側面に亘ってエレベータかごと昇降路の間に広げられ、昇降路内の空間を上下に仕切る第1の遮煙部材と、第1の遮煙部材を展開させる第1の展開手段とを備えたエレベータ用遮煙装置を提供する。さらに、エレベータかごの出入口が設けられた側の外側面に格納状態で取り付けられ、展開されたときに、出入口の全周囲に亘ってエレベータかごと昇降路の間に広げられ、昇降路内の空間を出入口と昇降路の間の空間とその他の空間とに仕切る第2の遮煙部材と、第2の遮煙部材を展開させる第2の展開手段とを備えてもよい。【選択図】 図4
