CLOSING DEVICE FOR FIRE SHUTTER
To simplify the whole constitution of a closing device including a restoring device.SOLUTION: An automatic closing mechanism, including a movable body (a first slider 60) biased from a first position to a second position, holding means for holding the movable body 60 at the first position, and a wire W3 having one end connected to the holding means and the other end provided with a manual operation part, is operated to move the movable body 60 from the first position to the second position by an operation of a solenoid 63 based on a fire detection signal. A manual closing mechanism operated to release the tension state of the wire W3 and move movable body and holding means to a second position by the operation from a manual operation part is restored by moving the movable body and the holding means at the second position to a first position by pulling the loosened wire W3 to the other end side to be in the tension state by the operation of the manual operation part in a state where the movable body and the holding means are locked at the second position.SELECTED DRAWING: Figure 22
【課題】復旧装置を含めた閉鎖装置全体の構成をシンプルにする。【解決手段】第１位置から第２位置へ向かって付勢されている可動体（第１スライダ６０）と、可動体６０を第１位置に保持する保持手段と、一端が保持手段に連結され、他端側に手動操作部が設けられたワイヤＷ３と、を備え、火災検知信号に基づくソレノイド６３の作動によって、可動体６０を第１位置から第２位置へ移動させるように作動した自動閉鎖機構、手動操作部からの操作で、ワイヤＷ３の緊張状態を解除して、可動体及び保持手段を第２位置へ移動させるように作動した手動閉鎖機構は、第２位置で可動体と保持手段が係止した状態で、手動操作部の操作によって、緩んだワイヤＷ３を他端側に引っ張って緊張状態とすることで、第２位置にある可動体及び保持手段を第１位置に移動させることで復旧される。【選択図】図２２
