Description of the Related Art Generally, a shutter device has a shutter in which a plurality of vertically divided first shutter members are rotatably connected to each other at a dividing position, and a winding device that winds the shutter down to raise and lower the shutter. A shutter box that houses a drive device that rotates the take-up drum and the take-up drum is provided, and guide rails that are respectively disposed on both sides of the shutter and that guide the shutter up and down.

The shutter device having such a structure is
Guide rails are embedded in both side walls of the entrances and exits of buildings and garages. In the installed state, when the shutter is wound up by the winding drum, the shutter rises to open the doorway, and when the shutter is wound down, the shutter descends to close the doorway.

By the way, the shutter device has a function of opening and closing a door closed by a shutter so that a person can enter and exit from the outside.
When a fire occurs inside a building, etc., the doors are closed with a shutter to prevent outside air from entering the interior of the building and prevent the fire from spreading to the outside. It also has the function of.

In this case, a person who is left inside after the entrance is closed needs to quickly escape to the outside. There was an emergency door.

However, if the emergency door is provided adjacent to the shutter device in this manner, the appearance is spoiled and a construction work is required to form an opening for providing the emergency door separately in a building or the like, which results in a construction cost. There was a problem of rising prices.

Further, for example, if a shutter device is installed at the entrance of a vehicle in a parking lot and an emergency door is installed adjacent to the shutter device, the width of the shutter is increased to secure a space for installing the emergency door. It must be narrow. Therefore, there is also a problem that the width in which the vehicle can go in and out becomes narrow.

Further, it comprises a shutter device having a notch formed in the lower part of the shutter and an emergency door having a shape corresponding to the notch, and the notch lowers the emergency door when the shutter is lowered. A method has been proposed in which the notch and the emergency door are fitted together, and the emergency door left when the shutter rises is stored separately, but in this method, the notch moves down the emergency door. There is a problem that it requires a great deal of work because it requires the work of accurately arranging it in the position where it should be placed and the work of separately storing the emergency door.

At the upper ends of the guide rails 4a and 4b,
As shown in FIG. 5, the locking portions 16 that are bent outward are formed. The above-described locking protrusion 2a is locked to each locking portion 16.

The shutter device 1 thus configured
Is the side wall S of the entrance of a building or garage (see Fig. 4)
, The guide rails 4a and 4b are installed in a buried state. In the installed state, the shutter box 3 is arranged above the doorway. In this embodiment, the rear side in FIG. 1 is the inside of a building or the like.

Then, when the winding drum housed in the shutter box 3 is rotated from the state shown in FIG. 1 to wind up the shutter 2, the emergency door 7 is also integrally wound up. It rises with the shutter 2 and the doorway is opened. On the contrary, when the shutter 2 is rolled down, the emergency door 7 is also rolled down as a unit, whereby the shutter 2 descends, the lowermost end of the shutter 2 is grounded, and the doorway is closed. At this time, as described above, the locking projections 2a are formed on both sides of the upper end portion of the shutter 2, respectively.
To the lowermost end of the guide rail 4a (4b) is approximately the same as or slightly longer than the vertical dimension. Therefore, when the shutter 2 is grounded, the locking projection 2a is locked by the locking portion 16 of the guide rail 4a (4b), and the lowering of the shutter 2 is reliably stopped.

When a fire or the like occurs inside the building after the doorway is closed, a person left behind inside the building can push the emergency door 7 from the inside and open it forward to open it from the opening 6. You can quickly escape to the outside. After all of the people have escaped to the outside, the emergency door 7 is closed and rotated by the biasing force of the coil spring 14 to be returned to the closed position.

In the shutter device 1 having the above structure,
There is an emergency door 7 in the opening 6 formed at the lower right of the shutter 2.
Is rotatably provided. Therefore, it is not necessary to separately provide an emergency door adjacent to the shutter device as in the conventional case. As a result, the appearance is improved, and construction work for forming an opening for installing an emergency door in a building or the like is not necessary, so that the construction cost can be reduced.

Further, when the shutter device is installed at the entrance / exit of the vehicle in the parking lot, it is not necessary to secure an installation space for the emergency door at a position adjacent to the shutter device as in the conventional case. Therefore, the width of the shutter can be expanded to the position of the emergency door which is conventionally installed adjacent to the shutter device. As a result, it is possible to widen the width of entry and exit of the vehicle.

Furthermore, when the shutter 2 is wound up and down by the winding drum, the emergency door 7 is wound up and down together with the shutter 2 and moves up and down together with the shutter 2. Therefore, unlike the conventional case, the work of accurately arranging the emergency door at the position where the cutout portion descends and the work of separately storing the emergency door are unnecessary.
