FIRE SHUTTER
PROBLEM TO BE SOLVED: To provide a fire shutter which performs restoration of an automatic closing device and a closing as necessary by a manual closing device at the same place.SOLUTION: A fire shutter includes: a shutter curtain 1 descending by the self-weight by release of a brake; an automatic closing device 6 activated based on a fire detection signal and releasing the brake; a manual closing device including a manual closing operation body (emergency closing switch 103) for releasing the brake manually; an automatic closing device restoration operation body (automatic closing device restoration lever 106) for restoring the activated automatic closing device 6; and an operation box (second operation box 10B) including a lid body (second lid body 102) which can be locked. The manual closing operation body (emergency closing switch 103) can be operated in a state where the lid body (second lid body 102) is closed. The automatic closing device restoration operation body (automatic closing device restoration lever 106) cannot be operated in a state where the lid body (second lid body 102) is closed, and it can be operated in a state where the lid body (second lid body 102) is opened.SELECTED DRAWING: Figure 34
【課題】自動閉鎖装置の復旧と手動閉鎖装置による随時閉鎖を同じ箇所で行うようにした防火シャッターを提供する。【解決手段】ブレーキ解放によって自重降下するシャッターカーテン１と、火災検知信号に基づいて作動してブレーキを解放する自動閉鎖装置６と、手動でブレーキを解放する手動閉鎖操作体（非常時閉鎖スイッチ１０３）を備えた手動閉鎖装置と、作動した自動閉鎖装置６を復旧させる自動閉鎖装置復旧操作体（自動閉鎖装置復旧レバー１０６）と、施解錠可能な蓋体（第２蓋体１０２）を備えた操作ボックス（第２操作ボックス１０Ｂ）と、を備え、手動閉鎖操作体（非常時閉鎖スイッチ１０３）は、蓋体（第２蓋体１０２）が閉鎖された状態で操作可能であり、自動閉鎖装置復旧操作体（自動閉鎖装置復旧レバー１０６）は、蓋体（第２蓋体１０２）が閉鎖された状態では操作不能であり、蓋体（第２蓋体１０２）が開放された状態で操作可能である。【選択図】図３４
