To provide an inspection support window apparatus for an elevator smoke sensor configured to perform, from the inside of a car, inspection work of a smoke sensor provided within a hoistway of an elevator.SOLUTION: An inspection support window apparatus 70 for an elevator smoke sensor comprises an opening part 72 which is provided at a position opposed to a smoke sensor 16 at a ceiling part 44 of a car 40, and allows a tester 60 with a gripping rod for operation check of the smoke sensor 16 to pass therethrough. Moreover, the inspection support window apparatus comprises: a cover part 74 which is large enough to cover the opening part 72; and an electric lock 76 which brings the cover part 74 into an unlocked state or a locked state with respect to the ceiling part 44 by an electric signal. Furthermore, the inspection support window apparatus comprises a cover opening/closing mechanism which brings, when the electric lock 76 is in the unlocked state, the cover part 74 into an open state by pressing force generated by moving the tester 60 with the gripping rod upward in a state where a tip of the tester 60 with the gripping rod is pushed to the cover part 74 from the inside of the car 40, and brings the cover part 74 back into a closed state when the pressing force is removed.SELECTED DRAWING: Figure 1
【課題】エレベーターの昇降路内に設けられる煙感知器の点検作業を乗りかご内から行えるようにすることである。【解決手段】エレベーター煙感知器用の点検支援窓装置70は、乗りかご40の天井部44において煙感知器16に対向する位置に設けられ、煙感知器16の動作確認用の把持棒付き試験器60を通す開口部72を含む。そして、開口部72を覆う大きさの蓋部74と、電気信号によって天井部44に対し蓋部74を開錠状態または施錠状態にする電気錠76を含む。さらに、電気錠76が開錠状態の場合に、乗りかご40内から把持棒付き試験器60の先端を蓋部74に押し付けた状態で把持棒付き試験器60を上方に移動させることで生じる押し力で蓋部74を開状態とし、押し力が除去されると蓋部74を閉状態に戻す蓋開閉機構を備える。【選択図】図1
