PROBLEM TO BE SOLVED: To provide a platform door smoke blocking device of elevator preventing a smoke blocking body from always contacting with a platform threshold to avoid decreasing of air tightness because the smoke blocking body is worn early and generating of slide noise between the smoke blocking body and the platform threshold.SOLUTION: A platform door smoke blocking device of elevator blocking a gap between a platform door and a platform threshold comprises: a smoke blocking body that is provided to a bottom end of the platform door and can slide to the vertical direction for the platform door; a rotor provided in the platform door, rotating in conjunction with switching actions of the platform door and sliding the smoke blocking body to the vertical direction; and an arm system provided to the rotor and rotating the rotor depending on the switching actions of the platform door.SELECTED DRAWING: Figure 1
【課題】遮煙体が乗場敷居に常に接触した状態になることを防止し、遮煙体が早期に摩耗して気密性が低下したり、遮煙体と乗場敷居との摺動音が発生したりすることのないエレベーターの乗場ドア遮煙装置を得る。【解決手段】エレベーターの乗場ドアと乗場敷居との隙間を塞ぐエレベーターの乗場ドア遮煙装置であって、乗場ドアの下端部に設けられ、乗場ドアに対して上下方向にスライド可能な遮煙体と、乗場ドア内に設けられ、乗場ドアの開閉動作と連動して回転し、遮煙体を上下方向にスライドさせる回転体と、回転体に設けられ、乗場ドアの開閉動作に応じて回転体を回転させるアーム機構と、を備えたものである。【選択図】図1
