Claims

[Scope of claim for utility model registration] A door at the upper end of the fixed door in a door opening/closing device that opens and closes the movable door by sliding it toward the fixed door, and in an emergency, rotates the movable door together with the fixed door to widen the opening. The front side is locked invisibly through an electromagnetic release, and the electromagnetic release is operated in an emergency to release the lock of the fixed door.A support shaft is provided protruding from the upper end of the wall of the fixed door, and a support shaft is provided on the upper end of the wall of the fixed door. The movable door is connected to a means for applying rotational force to a support shaft such as a weight, a torsion spring, or a rotational drive motor, and both sides of the upper end of the movable door are connected via a hanging frame to a driving means installed inside the opening. Of these, the fixed door side holds the movable door rotatably, and the door end side holds the movable door so that it can be released by pressing from inside, and the movable door and the fixed door are mutually connected when the movable door is in the open position. It is characterized by a structure in which an engaging metal fitting is provided, and the rotating force is used to rotate the fixed door, which is unlocked from the blind in an emergency, by the upper means, and the movable door is rotated in conjunction with the hooking metal fitting. Door opening/closing device.
