[Problems to be solved by the invention]
In a conventional shutter with an emergency exit in which a slat rises and descends along a pair of conventional guide rails, the operating force required to push and open the slat in an emergency is large, and since an open area required for a wheelchair or the like cannot be obtained, There is a problem that it is difficult to evacuate the elderly, children, injured persons, physically handicapped persons, and the like in an emergency.
[0006]
Further, in a conventional shutter with an emergency exit of a type in which a door portion or a vertical slit portion is formed in a part of the shutter sheet (hereinafter, referred to as a "slit portion opening / closing method"), the shutter sheet moves up and down along a pair of opposed guide rails. The shutter sheet needs to be able to be wound and unwound by a winding device, so that a door or a slit formed on a part of the shutter sheet can be wound and unwound by the winding device. Because of the necessity, the latch and the like can be arranged only under the shutter sheet. Due to such a structural limitation, in the case of the shutter with an emergency exit of the slit opening and closing method, particularly when used as an evacuation facility in the event of a fire in a building, etc., the shutter sheet is formed on the shutter sheet by wind pressure even when the emergency exit is not opened.

In the state where the hinged door is closed, a winding device 2 constituting the hinged door and a door stop (for example, 7 and 8 in FIG. 2) with which the left and right guide rails 3 and 4 come into contact are provided. By arranging a flexible seal member between the rails 3 and 4 and the door stop, the winding device 2 can prevent smoke and the like from flowing between the left and right guide rails 3 and 4 and the door stop to the evacuation road side. Leakage can be suppressed. Further, between the shutter sheet 1 and the left and right guide rails 3 and 4, by adopting the configuration as shown in FIG. 2, the band-shaped members 1c and 1c of the respective edge portions 1b of the shutter sheet 1 are formed as described above. And the guide rails 3 (4) are in contact with the back surfaces of the opposed inclined walls 3b, 3b (4b, 4b), so that smoke and the like leak from the space between the shutter sheet 1 and the left and right guide rails 3 and 4 to the evacuation road side. Can be suppressed. Further, by providing a flexible sealing member also in the opening at the lower part of the winding device 2 through which the shutter sheet 1 passes, the opening can be sealed. Furthermore, a flexible seal member is provided below the weight member 6 in the gap between the floor surface FL and the weight member 6, so that smoke and the like from the gap between the floor surface FL and the weight member 6 to the evacuation road side can be obtained. Leakage can be suppressed.
[0027]
The shutter sheet 1 is preferably formed by coating a heat-resistant resin such as a fluororesin on a base cloth made of a heat-resistant fiber, for example. Further, the seal member disposed between the winding device 2, the left and right guide rails 3 and 4 and the door stop, the opening at the lower portion of the winding device 2, and the gap between the floor surface FL and the weight member 6, It is preferable to use a heat-resistant flexible material. For example, as the sealing member, synthetic rubber such as silicon rubber or fluorine rubber can be used.
[0028]
As described above, in the case where the shutter with an emergency exit according to Embodiment 1 of the present invention is used as an evacuation facility in the event of a fire in a building, etc., it is possible to suppress the leakage of smoke and the like, and the present invention provides a method for opening and closing a slit. Since it is not a system, smoke and the like do not leak from the shutter sheet to the evacuation road side even when wind pressure or the like is applied.
[0029]
In the opening and closing of the hinged door in FIG. 2, the evacuee operates the operating means 11 by using a door closer that is commonly used for residences and the like, which can automatically close the hinged door after manually opening the hinged door. Then, after the door is opened and evacuated in the direction of arrow A in FIG. 2, the door can be securely closed, so that the fireproof and smokeproof function after evacuation can be ensured in the shutter with an emergency exit according to the present invention. it can. Alternatively, instead of the door closer, the hinge member 5 may be used as a hanging shaft, and the hanging shaft may be rotated by a motor or the like to drive the hinged door, or the swing door may be driven by a motor or the like via an arm or the like.
[0030]
In the above description, the case where the take-up device 2 and the pair of opposed guide rails 3 and 4 form a three-way frame to form the hinged door has been described. However, the weight member 6 below the shutter sheet 1 in FIG. The weight member 6 and the guide rails 3 and 4 may be connected to each other by a latch mechanism or the like in a state where the shutter is closed. In this case, since the take-up device 2, the pair of opposed guide rails 3 and 4, and the four-sided frame of the hinged door made of the core material are formed, a more rigid and stable hinged door frame can be formed.
[0031]
Embodiment 2 FIG.

In an emergency, when the shutter sheet 1 is closed, the evacuee needs to open the lower divided core member 13b and the lower part thereof as shown by the arrow A in FIG. Secure space and evacuate in the direction of arrow B. As described above, since the lower divided core member 13b and the lower part of the shutter with emergency exit 102 open and close as hinged doors, a sufficient passage (evacuation route) S for evacuation can be secured. That is, for example, even in a narrow space such as a landing door of an elevator, a ceiling storage type emergency exit shutter having an opening close to the effective opening can be installed. Further, since the hinge members 5, 5 having a substantially vertical rotation axis support the weight of the hinged door, the evacuee does not need to support the weight by hand, and can perform the opening / closing operation with a small operation force. Since the winding device 2 does not rotate as compared with the configuration of the first embodiment, the moment of inertia of the hinged door is reduced, and the operating force for opening and closing the hinged door can be further reduced.
