As another method, an unlocking switch for opening (not shown) is provided on the outer wall surface, and the lock device (5) is operated by the control device (4) to open and close both opening and closing doors.
It is also possible to close (1) and (2) and give priority to the one whose unlock switch for opening is activated earlier. In this way, various methods are devised so that the double-sided doors (1) and (2) are not opened at the same time.

It goes without saying that the opening / closing doors (1) and (2) may be of the double door type as shown in FIG. 1 or the sliding door type as shown in FIG. In the case of the sliding door method, as a rule, the solenoid (5) is installed in a direction perpendicular to the sliding doors (1) and (2).

In case of a power failure, electric power may be supplied from a separate generator, or the lock device (5) may be a normally closed type, and both doors (1) are opened by the lock device (5) during a power failure. ) (2) may be closed. In addition, one may be a normally closed type and the other may be a normally open type so as to limit the use from only one side.

In the above description, the case where the door is two is described as an example, but the present invention is not limited to this, and includes the case where N doors are provided in one room (3). Even in that case, when using the room (3), there are N open / close doors.
(1)… (N) except for the door opened by the person entering the room
Other doors are locked and only one door can be used
However, since the principle is the same as that of the case where the doors are provided at two places, the description thereof will be omitted.

[0022]

According to the present invention, two opening / closing doors provided in a room can be freely opened / closed when no person is inside the room, and both doors are closed when a person enters the room. The other person to enter the room, and when the person entering the room goes out of the room, only the door used by the person to enter the room should be opened and closed, while the other door remains closed. Since the opening and closing doors are controlled so that both opening and closing doors do not open at the same time in any case, the advantage of being able to secure private and at the same time save space There is. Further, as in claim 2, it is of course possible to provide the door at N positions, and in this case, more space saving is possible.
