Of course, it must be able to satisfy various functions such as preventing the emission of flame and toxic gas to the outside.

Furthermore, in the case of blocking a specific space due to the occurrence of an emergency situation such as a fire, an emergency exit for rapid escape of those who remain in the sealed space is necessary, and such an emergency exit is within a range that does not impair the function required above. There is a structural constraint to be installed.

Therefore, the most common form is to cut off one corner of the lower side of the shutter plate and then install an independent emergency door that is stored separately. However, this type of emergency door has the emergency door fixed at the point corresponding to the edge cutout of the shutter plate before the shutter plate is lowered when using the fire shutter, so that the emergency door is fixed by the descending shutter plate, and the shutter plate is wound. When raising, the emergency door should be separated from the shutter plate and stored separately, and it is impossible to install it quickly in an emergency situation such as a fire due to many difficulties in installing and managing the emergency door.

In view of these problems, the shutters for providing an emergency door when the shutter plate descends by providing an emergency door integrally with the shutter plate, although Utility Model Publication Nos. 72-494 and 93-6476 are introduced. Of the shutters are satisfied with the fact that the emergency doors are integrally installed on the shutter plate, but because of the lack of shielding that the fire shutters must be equipped with, the closures that cannot suppress the emission of flames and toxic gases from the fire zone are pointed out. It is.
