シャッターが提案されている。2. Description of the Related Art Fire protection equipment such as fire barriers and shutters for blocking flames and smoke, fire prevention doors for people to evacuate, etc. have been installed inside the building in case of fire. Evacuation passages, etc. have been systematically deployed. Recently, as a new fire prevention equipment to replace these fire prevention bulkheads and fire prevention shutters, there has been proposed a fire and smoke prevention screen shutter that uses a non-combustible or fire resistant screen curtain to block flames and smoke.

低下してしまう。However, in the screen shutter for fire and smoke prevention using the screen curtain, since the opening / closing door is formed in the screen curtain, the sealing property of the opening / closing part of the opening / closing door is butt-matched with the screen curtain. Will be done by. However, since the screen curtain is flexible and lightweight, when the door is closed, a gap is apt to occur at the abutting part with the opening / closing part, and the opening / closing door is opened due to the pressure difference between the inside and outside of the screen shutter due to a fire. It is pushed open and a gap occurs. The screen shutter is required to have airtightness from the viewpoint of fire prevention and smoke prevention, but as described above, if a gap occurs in the opening and closing door part, air may flow in or smoke may flow out from there,
The function as a screen shutter for fire and smoke will be significantly reduced.

１４の気密性を保持することができる。Since the opening / closing mechanism 36 is provided between the weight 24 for the overlapping curtain and the weight 26 for the screen, the overlapping curtain 20 is opened as the opening / closing door 16 is opened, and the opening / closing door 16 is opened. With the closing, the overlapping curtain 20
Can be closed automatically. Therefore, the opening / closing mechanism 3
When the opening / closing door 16 of the evacuation opening 34 is opened by 6, the overlapping curtain 20 in the opening direction is opened, so that the overlapping curtain 20 does not become an obstacle when the opening / closing door 16 is next closed, and When the opening / closing door 16 is closed, the overlapping curtain 20 is closed. Therefore, it is not necessary to open / close the overlapping curtain 20 each time the opening / closing door 16 is opened / closed, and the airtightness of the slit 14 can be maintained.

Therefore, by releasing the opening force of the opening / closing door 16, the opening / closing door 16 is moved to the door weight 2.
After being automatically closed by the self-weight of 2, the opening / closing door 16 can be surely closed after the evacuation from the evacuation port 34, and the hermeticity of the screen shutter 10 can be maintained.

Although the case where the closed state of the overlapping curtain 20 is held is disclosed, the line of action connecting the attachment points of both ends of the spring 38 for urging the overlapping curtain 20 in the opening direction is inward from the opening center of the hinge member 30. By configuring it to be located at
The closed state of the overlapping curtain 20 can be held by the spring 38. The opening / closing mechanism 36 is the spring 3
