In the lower part of the internal space between the door-end side expected surface 800 of the evacuation opening of the sleeve door 2 and the door-end side end surface 20 of the sleeve door 2, the drop bar 90 is adjacent to the door-end side expected surface 800. Is provided so that it can be moved up and down, and the dropping bar 90 can be moved up and down by the turning operation of the operation lever 92 provided on the door-side expected surface 800 of the evacuation opening. At the position where the drop bar 90 is moved downward, the lower end side of the drop bar 90 protrudes downward from the lower surface 23 of the sleeve door 2 and is in a locked state in which the drop bar 90 is locked to a locked portion 91 formed on the floor surface. At the position where the drop bar 90 is moved upward, the lower end of the drop bar 90 is retracted inside the sleeve door 2, and the lower end of the drop bar 90 is in an unlocked state released from the locked portion 91.

The operation lever 92 can be accommodated substantially flush with the door-side expected surface 800 of the evacuation opening when the drop bar 90 is operated to move downward or upward, and the operation lever 92 closes the sliding door 3. Does not interfere with posture. When the submerged door 3 is in the closed position, the door end side end surface 30 of the submerged door 3 comes close to the door end side expected surface 800 of the evacuation opening and covers the operation lever 92 so that the drop bar 90 is moved upward by the operation lever 92 Operation is restricted.

Accordingly, when the sleeve door interlocking fire and smoke prevention shutter device is used for management, first, in a state where the opening portion is closed by the sleeve door 2, the sliding door 3 is opened to the open posture, and the dropping rod is operated by the operation lever 92. 90 is moved downward and the lower end side of the drop bar 90 is locked to a non-locking portion 91 formed on the floor surface to be in a locked state. Then, the door 3 is closed and closed, and the door 3 is locked to restrict the opening of the door 3. Next, the shutter curtain 1 is lowered by the push button switch to fully close the opening. In the fully closed state of the opening, the operation lever 92 can be prevented from being operated from the outside, and the anti-theft property can be ensured.

Since the drop bar 90 always moves up and down inside the sleeve door 2 and only protrudes downward from the lower surface 23 of the sleeve door 2 only in the locked state, the drop bar 90 and the operation lever 92 are provided on the surface portions 24 and 25 of the sleeve door 2. It is excellent in design without being exposed to. In particular, when the sleeve door 2 is in the storage posture stored in the storage unit 50, the drop bar 90 and the operation lever 92 are not exposed to the outside. In the present embodiment, the lock rod protruding from the lower surface of the door body, that is, the dropping rod 90 has been described. However, the lock rod according to the present invention may protrude from the upper surface of the door body.

Another embodiment of the present invention will be described based on a fire door device with a sliding door. The fire door device with a sliding door includes a main door 2 ′ and a sliding door 3 ′ for evacuation.

The main door 2 ′ includes a door end side end surface 20 ′, a door bottom side end surface 21 ′, an upper end surface 22 ′, a lower end surface 23 ′, and opposing surface portions 24 ′ and 25 ′. The door bottom side (base end side) of the main door 2 ′ is supported so as to be rotatable with respect to the housing via a rotation support shaft 26 ′. In one embodiment, the main door 2 'has a storage posture that extends parallel to the side wall (not shown), and a posture that extends perpendicularly to the side wall, that is, a closed posture that extends in the width direction of the opening. The main door 2 ′ rotates from the stowed position to the closed position in the event of a fire and partitions a predetermined part of the building interior space.

The main door 2 'is provided with an evacuation opening through the surface portions 24' and 25 ', and the evacuation opening can be opened and closed by a submerged door 3'.

The submerged door 3 ′ includes a door end side end surface 30 ′, a door butt side end surface 31 ′, an upper end surface 32 ′, a lower end surface 33 ′, and opposing surface portions 34 ′ and 35 ′. The end side is supported so as to be rotatable with respect to the eaves of the evacuation opening via a rotation support shaft 36 '.

The locking means of the locking device 9 is such that the dropping bar 90 provided in the main door 2 ′ so as to be movable up and down and the tip of the dropping bar 90 protruding downward from the lower surface 23 ′ of the door body 2 are locked. A locked portion 91 that is recessed in the surface and an operation lever 92 that moves the drop bar 90 up and down are provided. The operation lever 92 is provided on the door-side expected surface of the evacuation opening. When the door 3 'is in the closed position, the door-side end surface 30' of the door 3 'is on the door-side expected surface of the evacuation opening. By covering the operation lever 92 in proximity, the upward movement operation of the drop bar 90 by the operation lever 92 is restricted.

Therefore, by locking the door 3 'in the closed state and restricting the opening of the door 3', the operation lever 92 cannot be operated from the outside, and the anti-theft property can be ensured. Further, the lock device cannot be unlocked unless the door 3 'is opened. Moreover, since the drop bar 90 and the operation lever 92 are not exposed to the surface part of the main door 2 ', the design is excellent. Here, a fire door device with a sliding door can be used for management, but when a fire door device with a sliding door is used for management, conventionally, it has been necessary to provide a locking device on the main door. In this embodiment, the locked state of the locking device cannot be released unless the door 3 'is opened. Therefore, by providing the locking device 38 only on the door 3', the locking device is not necessarily provided on the main door 2 '. There is no need to provide it, and the number of parts and cost can be reduced. It should be noted that handles H1 and H2 for manually opening the door bodies are provided on the sliding door 3 'and the main door 2', respectively.

INDUSTRIAL APPLICABILITY The present invention can be used for a fire door device with a sleeve door interlocking fire and smoke shutter and a sliding door.
