It is a figure which shows an example of the conventional opening / closing body apparatus. It is a figure which shows schematic structure of the fire prevention shutter apparatus which is an opening-closing body apparatus which concerns on this invention. It is a figure which shows the detailed structure of a fire door. It is a figure which shows the detail of the relationship between a fire door, the door stop of the upper part of a lintel, and a floor surface. It is a detailed block diagram which shows the internal structure of a fire door.

  Hereinafter, a fire shutter device will be described as an example of an opening / closing device according to the present invention with reference to the accompanying drawings. FIG. 2 is a diagram showing a schematic configuration of a fire shutter device which is an opening / closing body device according to the present invention. This fire-proof shutter device is normally in an open state in which the opening / closing machine 1 is housed in a housing part provided above the peripheral edge of the opening by winding the shutter curtain 4 around a winding shaft (not shown). As another example, there is a case in which the shutter curtain is stored in the storage unit without being wound and is opened. This open state is maintained by being mechanically held by the brake 2. Then, in the event of a fire, the automatic closing device 3 is provided with a disaster prevention signal BS and an electric manual closure from the sensor 15 (or an interlocking controller connected to the sensor or a disaster prevention panel) input via the interlocking relay 5. In response to the operation signal of the device 7 (including the emergency shutter closing button), the opening is closed by releasing the hold of the brake 2 and letting out the shutter curtain 4 from the storage portion by its own weight by natural descent. (Partition), and a predetermined fire prevention compartment is formed.

  The sensor 15 for outputting the disaster prevention signal BS to the interlocking repeater, the interlocking controller connected to the sensor, the disaster prevention panel, and the like are appropriately selected and provided depending on the installation environment. A plurality of sensors may be provided, but when one or more of the plurality of sensors are detected, the number of disaster prevention signals corresponding to the detection of the plurality of disaster prevention BSs is input to the interlocking repeater. Alternatively, a single disaster prevention signal BS may be input to the interlocking repeater when one or more of a plurality of sensors are detected. The disaster prevention signal BS output from the interlock controller connected to the disaster prevention panel or sensor is often a voltage signal such as DC 24V, but the disaster prevention signal BS output from the sensor is a non-voltage signal. Therefore, the interlocking repeater can be appropriately adapted to the inputted disaster prevention signal BS.

  The opening / closing machine 1 is a drive motor for opening and closing the shutter curtain 4 electrically. In the normal time when the shutter curtain 4 does not need to be opened and closed, the shutter 1 may be configured only by the brake 2 instead of the switch 1 and the brake 2 which are driving sources as illustrated. When the disaster prevention signal BS is input, the interlocking relay 5 outputs a DC 24V signal that is a voltage signal to the automatic closing device 3. The interlock repeater 5 normally uses a commercial power supply 16 to output a DC 24V signal, but at the time of a power failure or the like, the interlock repeater 5 is powered by power from a standby power supply (battery such as a storage battery) built in the interlock repeater 5 DC 24V signal is output.

  The automatic closing device 3 is a commercial power source 16 supplied via the interlocking relay 5 or a standby power source (storage battery) built in the interlocking relay 5 like a known automatic closing device used for a conventional fire shutter or the like. It operates according to the electric power (DC 24V signal) from. Further, the automatic closing device 3 operates using the power of the 24V signal supplied from the interlocking relay 5 having a built-in shutter power supply, so that even if there is no supply of commercial power to the fire prevention shutter device 10 in the event of a fire. The brake 2 is released based on the disaster prevention signal BS input from the sensor 15 or the like, and the shutter curtain 4 having a fire prevention structure in the wound state is lowered by its own weight, so that the opening can be automatically closed. ing.

  The electric manual closing device 7 is mainly used for operating a shutter for opening and closing the shutter electrically operated and manually inputting a start signal for causing the interlock repeater to perform the same operation as when the disaster prevention signal BS is input. It is. The electric manual closing device 7 includes an input switch (push button switch) for normal operation corresponding to an instruction to open / close the shutter curtain to the switch 1, an operation button that is an emergency shutter closing button, a recovery button, It includes a battery test button and the like, and further includes various display means for displaying the battery test result, displaying the status of the standby power supply, and displaying the code disconnection status. Although the electric manual closing device 7 is illustrated above the fire door 12 in FIG. 2, it is actually installed at a position where a person such as a housing near the fire door 12 can operate. In particular, the operation button of the electric manual closing device 7 is covered with a resin transparent panel (push-break cap), and the emergency shutter closing button is configured to be operated by pushing the resin transparent panel in an emergency. (Actuation button).

  The fire shutter device 10 is provided with an obstacle sensing device that detects contact with an obstacle during opening and closing. As shown in the figure, the obstacle sensing device includes a seat switch 9 provided on the seat plate at the lower end of the shutter curtain 4, a wired obstacle sensing device 17 provided in the storage box of the shutter curtain 4, and these And a signal cord 11 that electrically connects the two. The seat plate switch 9 is attached to the seat plate of the shutter curtain 4 and has a built-in micro switch that closes the contact point when the seat plate comes into contact with an obstacle such as a person or an object. Then, it is transmitted as a sensing signal to the wired obstacle sensing device 17 via the signal code 11 in a wired manner. The signal code 11 is a cable that transmits the sensing signal of the seat board switch 9 to the wired obstacle sensing device 17. The cable is housed or guided by a cord reel, a movable pulley, or the like, so that it does not bend to obstruct the opening and closing of the shutter curtain 4.

  The wired obstacle sensing device 17 is normally operated by a commercial power supply, controls the operation of the switch 1 in response to the input of a sensing signal from the seat plate switch 9, and at least in the event of an emergency such as a fire. The obstacle detection signal from the plate switch 9 is through-outputted to the automatic closing device 3. The automatic closing device 3 stops the closing operation of the shutter curtain 4 according to the input of the obstacle detection signal from the wired obstacle detection device 17 and performs the avoidance operation. Therefore, when the shutter curtain 4 is lowered by its own weight in the event of a fire, if the seat plate or the like comes into contact with an obstacle and a detection signal is detected from the seat plate switch 9, the weight reduction of the shutter curtain 4 is stopped. The avoidance operation is performed. That is, when the obstacle detection signal is input while the shutter curtain 4 is being lowered, the wired obstacle detection device 17 normally performs control to stop the lowering operation of the shutter curtain 4 and raise it for a certain time. On the other hand, the wired obstacle detection device 17 detects the obstacle when the automatic closing device 3 is activated and an obstacle detection signal is input while the shutter curtain 4 is descending, such as when disaster prevention occurs. A signal is transmitted through to the automatic closing device 3, the operation of the automatic closing device 3 is stopped, the release state of the brake 2 of the switch 1 is returned, and the shutter curtain 4 is temporarily stopped.

  In a general configuration of a fire shutter device provided with a fire door in addition to the shutter curtain, guide rails provided on both sides of the shutter curtain 4 at the opening side end and an opening between the shutter curtain and the fire door There is a guide rail called a middle pillar provided in the section. In this embodiment, the guide rail 21 is provided on one side (left side in the drawing) of the shutter curtain 4, but there is no center pillar, and a concave groove is provided in a part of the side end of the fire door 12. It is used as the guide rail 22. Therefore, in the case of the opening / closing body device according to this embodiment, the guide rails do not exist on both sides of the shutter curtain 4 unless the fire door 12 is rotated and closed (partitioned).

  Therefore, in this embodiment, the closing confirmation switch 24 for closing the shutter curtain 4 in conjunction with the closing operation of the fire door 12 which is a sleeve door provided as a shielding door means is a door stop portion or an opening portion. The shutter curtain 4 starts to close when the fire door 12 is closed first and a closing confirmation signal is output from the closing confirmation switch 24. . The fire door 12 is always open, and is usually stored in a door pocket or the like provided on a column or wall on the side of the opening. In this normally open type fire door 12, an evacuation passage is secured by a diving door 121 provided separately in the closed fire door.

  The fire door 12 is normally restrained in an open state by a fire door automatic closing device (not shown), but if the restraint is released by the fire door automatic closing device, its own weight (using a so-called gravity hinge, etc.) and spring force It is configured to close by an urging force such as using a closer. The automatic closing device for fire doors is electrically connected to an external device power supply terminal (24 volt output terminal: terminal 24-0) provided in the interlock repeater, and the hazard prevention interlock repeater inputs an activation signal. Accordingly, when a voltage of 24 [V] is output as a voltage signal from the external device power supply terminal to the automatic closing device for the fire door, the fire door is unconstrained using the electric power and the fire door is closed. In addition, when a fire door manual closing device (emergency closing instruction means) is connected to the fire door automatic closing device, the fire door automatic closing device is also fire-proof by operating the fire door manual closing device. You can also release the door restraint and close the fire door. The automatic door closing device for a fire door may electrically output a closing instruction signal to the automatic door closing device for a fire door, or may mechanically actuate the automatic door closing device for a fire door. .

  The fire door 12 includes a fire door body, a guide rail 22, and a submerged door 121, and is usually housed in a door pocket provided on the side of the opening, and includes a disaster prevention signal BS and an electric manual closing device 7 (for emergency use). In response to the operation signal (including the shutter closing button), the shutter curtain 4 comes out of the door bag before the closing operation, rotates to close a part of the opening, and stops by contacting the upper door of the lintel. . Although not shown, an airtight material made of a glass cloth material, a chloroprene rubber material, or the like is provided at the fitting portion between the guide rail 22 and the shutter curtain 4, and also at the fitting portion between the fire door 12 and the column. Airtight materials made of glass cloth material, chloroprene rubber material, and the like are respectively attached. Further, an airtight material made of a rubber material or the like is attached to the lower end portion of the fire door 12 so as to block the gap between the fire door 12 and the floor surface. As a result, the gap between the guide rail 22 of the fire door 12 and the shutter curtain 4, the gap between the fire door 12 and the pillar, and the gap between the fire door 12 and the floor surface are respectively closed. Leakage can be prevented. An airtight material may be provided instead of the rubber material, and a rubber material may be provided instead of the airtight material.
