AUTOMATIC CLOSING DEVICE FOR FIRE DOOR
PROBLEM TO BE SOLVED: To provide an automatic closing device for a fire door capable of bringing a latch mechanism into a release state manually and easily without using a fire door.SOLUTION: When a fire breaks out, an automatic closing device 1 for a fire door can automatically close a fire door by bringing a latch mechanism part 3 into a release state by a start part starting, and by releasing engagement of a latch 3a and an engaging member H of the fire door, and it can also manually close the fire door by bringing the latch mechanism part 3 into a release state by pulling the fire door in a closing direction and by releasing engagement of the latch 3a and the engaging member H of the fire door. In a housing 2, an opening 10 for release operation is provided, and an operation of bringing the latch mechanism part 3 into a release state can be performed from the outside through the opening 10 for release operation.SELECTED DRAWING: Figure 4
【課題】防火戸を使用せずにラッチ機構を手動で容易に解除状態にすることのできる防火戸用自動閉鎖装置を提供する。【解決手段】火災発生時、起動部が起動することによりラッチ機構部３を解除状態にして、ラッチ３ａと防火戸の係合部材Ｈとの係合を解除し、防火戸を自動で閉鎖させることができると共に、防火戸を閉鎖方向に引っ張ることによりラッチ機構部３を解除状態にして、ラッチ３ａと防火戸の係合部材Ｈとの係合を解除し、防火戸を手動で閉鎖させることができる防火戸用自動閉鎖装置１において、筐体２に、解除操作用開口部１０を設け、その解除操作用開口部１０を通じて外部からラッチ機構部３を解除状態にする操作を可能にしたことを特徴とする。【選択図】図４
