It is related with the opening-and-closing body apparatus comprised so that.

  In general, in the construction of large buildings, etc., in passages and hall spaces inside structures, in the form of sheets or shutters that automatically close as soon as a fire occurs to prevent the spread of fire and the spread of smoke in the event of a fire Using a shielding member such as a fire curtain, there is provided a fire shutter device that operates to form a space three-dimensionally enclosed with pillars, walls, floors, etc., that is, a fire prevention section and a smoke prevention function. Some of these shutter devices are extended to partition an opening for fire prevention, smoke prevention, waterproofing, windproofing, crime prevention, etc. when a disaster other than a fire occurs or when a store is closed.

  FIG. 1 is a diagram showing a schematic configuration of a conventional fire shutter device that forms such a fire protection section. The disaster prevention opening / closing device such as the fire shutter device 10 is connected to the switch 1 in response to the output of a disaster prevention signal BS (for example, a 24V DC signal) from a disaster prevention panel that senses smoke and heat generated in the event of a fire. And an automatic closing device 4 for releasing the brake 2. The voltage value of the signal may not be 24 V, and the voltage value is determined as appropriate. The automatic closing device 4 operates with electric power from a commercial power supply 9 supplied via the repeater 3 or a standby power supply (storage battery) built in the repeater 3.

  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 can be released based on the inputted disaster prevention signal BS by the standby power source built in the repeater 3, and the fire prevention shutter in the winding state The curtain 5 can be lowered by its own weight to automatically close the opening. In an emergency, the shutter curtain 5 can be lowered by its own weight by operating the manual closing device 8 (emergency shutter closing button).

  FIG. 2 is a diagram showing a schematic configuration of the repeater 3 of FIG. As shown in FIG. 2, the repeater 3 includes a power supply circuit 31, a charging device 32, a standby power supply (storage battery) 33, a power supply switching device 34, and a control circuit 35. The power supply circuit 31 converts the commercial power supply 9 into a DC 24V signal, supplies a DC voltage to the control circuit 35 via the power supply switching device 34 and supplies power to the charging device 32. The charging device 32 charges the standby power supply (storage battery) 33 using the power from the power supply circuit 31. The standby power source (storage battery) 33 is composed of a lithium ion rechargeable battery or other battery (including a rechargeable type power source that can be used up like a dry battery) and the like, and a DC voltage control circuit via a power source switching device 34 35. The power supply switching device 34 selectively switches one of the power supply circuits 31 and the standby power supply 33 and connects it to the control circuit 35. Normally, since the power from the commercial power supply 9 is supplied, the DC voltage from the power supply circuit 31 is supplied to the control circuit 35. However, the power supply from the commercial power supply 9 is stopped in an emergency such as the occurrence of a fire. In some cases, the control circuit 35 operates to supply a DC voltage from the standby power supply 33. The return switch 36 is a switch for resetting the operation of the control circuit 35. In FIGS. 1 and 2, the connection relationship of the commercial power source other than the repeater 3 is not shown.

  As described above, the standby power supply 33 built in the repeater 3 is controlled from the repeater 3 connected to the sensor 11, the disaster prevention panel, or the sensor 11 even when no commercial power is supplied to the fire prevention shutter device 10 in the event of a fire. Based on the disaster prevention signal BS input to the circuit 35, an operation signal (DC 24V signal) is output, the automatic closing device 4 is operated, the brake 2 is released, and the brake 2 is released. The shutter curtain 5 having the structure can be lowered by its own weight to automatically close the opening. In an emergency, by operating the electric manual closing device 8 (emergency shutter closing button), an operation signal (DC 24V signal) is also output from the control circuit 35, and the automatic closing device 4 is operated to operate the brake 2 And the shutter curtain 5 can be lowered by its own weight.

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 transmitter 6 provided on a seat plate at the lower end of the shutter curtain 5 and a receiver 7 provided in a storage box of the shutter curtain 5. The transmitter 6 transmits a sensing signal to the receiver 7 in a wired or wireless manner when a seat plate switch (microswitch) is activated by an obstacle touching the seat plate. At this time, the automatic closing device 4 controls to stop the closing operation of the shutter curtain 5 in accordance with the input of the sensing signal. Accordingly, when the seat curtain comes into contact with an obstacle when the shutter curtain 5 is moving down due to the occurrence of a fire, the lowering of the weight of the shutter curtain 5 is stopped. An example of such a fire shutter device is disclosed in Patent Document 1.
JP 2002-81281 A

  In the conventional fire shutter device, the main purpose of providing the manual closing device is that the fire shutter can be operated by manual operation even if there is a problem in the disaster prevention signal path. In order to normally operate the obstacle sensing device provided at the front end of the closing side while the shutter curtain 5 is lowered by its own weight, it is essential to supply power. Therefore, the fire shutter device has a configuration in which a standby power source 33 is provided in the repeater 3 and can be operated by supplying power from the standby power source without supplying commercial power. Usually, the reserve power source is composed of lithium-ion rechargeable batteries and other batteries (including rechargeable batteries as well as power sources that can be used up like dry cells). It is essential to perform maintenance and inspection by replacement, etc. If the battery capacity is low or the battery is insufficient due to forgetting the inspection, it is difficult to operate the obstacle detection device normally during automatic lowering. Situation may occur.

  An object of the present invention is to provide an opening / closing body capable of notifying an administrator or the like of this fact at an early stage when the remaining electric capacity of a power source means such as a standby power source is reduced and inspection or replacement is required. To provide an apparatus.

The first feature of the opening / closing body device of the present invention is that the opening / closing body means provided at the peripheral edge of the opening and the opening / closing body means in response to an input of an artificial operation signal and a signal different from the operation signal. An automatic closing means for closing, an obstacle detecting means for causing the opening / closing body means in a closing operation to perform an avoidance operation when an obstacle is detected on an operation path of the opening / closing body means, and the obstacle sensing means Power supply means for supplying electric power, and operating means means provided in the housing, wherein the operation is performed by being manually operated via a transparent panel that can be pushed and broken provided in a part of the housing. There is provided an operator means for outputting a signal and a display means provided in the casing for displaying the remaining amount of electric capacity of the power supply means so as to be visible through the transparent panel.
Opening / closing body means can be used to open and close doors and windows, or openings such as internal passages and spaces in structures such as buildings, houses, factories, and warehouses, or shutter curtains that only move closed It is made up of an opening and closing member and a closing member, and is extended to partition the opening for fire prevention, smoke prevention, waterproofing, windproofing, crime prevention, etc. in the event of a disaster or closing. When the opening / closing means is, for example, a fire prevention / smoke prevention shutter curtain for forming a fire prevention section, the fire prevention shutter curtain is stored in an upper part which is one of the peripheral parts of an opening of a building or the like and passes through a lintel etc. Descends and closes the opening. In addition to this, the opening / closing body means may be housed in the side portion of the opening and opened / closed by a horizontal pulling method, or may be housed in the lower part of the opening and opened / closed by an ascending method. The opening / closing body means includes those that can be fully closed by closing and those that cannot be fully closed.
The artificial operation signal is generated, for example, when an operator means such as an emergency shutter closing button provided in the housing is artificially operated. Usually, since a transparent panel that can be pushed through is provided in a part of the casing, the operator means is manually operated by outputting the transparent panel and outputs an operation signal. Moreover, as a signal different from the operation signal, there is a disaster prevention signal or an emergency closing signal generated in the event of a fire or the like. By inputting these signals, the automatic closing means lowers the fire shutter curtain and closes the opening.
In such fire shutter curtains and the like, as an example, an obstacle sensing device that detects contact with an obstacle during opening and closing is provided on the seat plate at the front end of the closing side, and according to the sensing of the obstacle The shutter curtain is designed to perform the avoidance operation. The avoidance operation here includes a case where the descent of the shutter curtain is stopped, the descent speed is suppressed without reaching the stop, or the shutter curtain is raised from the sensed state. In addition, the obstacle sensing device includes a non-contact sensing device such as a contact-type device provided on a seat plate or the like at the front end of the closed side or an area sensor. Accordingly, the shutter curtain performs an avoidance operation when the seat plate comes into contact with an obstacle while the shutter curtain is moving under its own weight during automatic closing.
In this way, in order for the obstacle sensing device provided at the closed end, etc., to operate normally while the weight of the shutter curtain is descending, it is necessary to supply power stably even in situations where it is difficult to supply commercial power. Provided is a power source means such as a standby power source. Usually, the power supply means such as a backup power source is from a power source that can be used up like a dry battery, a rechargeable lithium ion rechargeable battery, and other batteries (including a power source that can be used up like a dry battery in addition to a rechargeable type). It has a long service life due to its construction. Therefore, when a power supply means such as a standby power supply is installed, it is necessary to carry out a maintenance check or the like to periodically replace the power supply means.
In the present invention, the display means for displaying that the remaining capacity of the electric capacity of the power supply means such as the standby power supply is reduced (including that it has disappeared) is provided in the housing containing the emergency shutter closing button. It is provided at a position where it can be visually confirmed through a transparent panel that can be pushed and broken provided in a part of the casing, and this display means promptly notifies an administrator or the like that inspection or replacement is necessary. I did it. In this way, by using the transparent panel of the existing casing, the display means can be provided so as to be visible without any special processing or the like for providing the display means, and the design of the casing itself is also improved. Can be improved.

According to a second feature of the opening / closing member device of the present invention, in the opening / closing member device described in the first feature, the display means is in the vicinity of the operator means and can be visually recognized through the transparent panel. It is to be provided at a proper position.
In this case, the display means is provided in the vicinity of the operator means which is an emergency shutter closing button in the housing. By providing in the vicinity of the operator means, visibility from the transparent panel is improved.

According to a third feature of the switchgear device of the present invention, in the switchgear device described in the first feature, the operator means itself indicates the remaining amount of electric capacity of the power supply means as the display means. It is to be displayed so as to be visible through the screen.
This is because the visibility from the transparent panel is further improved by constructing the display means integrally with the operator means which is an emergency shutter closing button.

According to a fourth feature of the switchgear device of the present invention, in the switchgear device described in the first, second or third feature, at least two of the power supply means are provided, and the two power supply means are provided in different systems. The power is supplied to the automatic closing means and the obstacle sensing means.
In this system, two power supply means are provided, and power is supplied to the automatic closing means and the obstacle sensing means in different systems. By providing at least two power supply means in this way, even if one power supply means cannot be used due to its life or cannot be used due to some trouble, power can be supplied from the other power supply means. Operational safety can be increased. Further, by alternately exchanging the two power supply means at about half of their lifetimes, it is possible to reduce the occurrence of the end of the life of the power supply means.
It should be noted that the term “displayably visible” described in each feature of the opening / closing body device of the present invention only needs to be directly or indirectly visually recognized, and the display content is visually reflected, transmitted, or translucent. This includes things that should be recognized. The display mode may be any type, for example, a display based on the presence or absence of light emission (or brightness), a display based on a difference in the flashing mode of light, a display based on a difference in color development, or a difference in direction. There are various things such as display, display due to differences in shape (projection size of protrusions, etc.), display due to differences in display characters (symbols) and display modes, display due to meter display and display due to differences in movement, etc. By displaying simply by the presence or absence of light emission, there is an advantage that a complicated structure is not required and visibility is good.

  According to the fire shutter device of the present invention, when the remaining amount of electric capacity of the power source means such as a standby power source is reduced and inspection or replacement becomes necessary, this fact is notified to the manager etc. at an early stage. There is an effect that can be.

  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. 3 is a view 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 a shutter opening / closing device 50 (comprising a drive source, a brake, etc.) basically winds up a shutter curtain 5. This open state is maintained by being mechanically held by a brake. Then, in the event of a fire, the automatic opening / closing device 4 keeps the open state by the brake according to the disaster prevention signal BS input via the repeater 3 and the operation signal of the manual closing device 8 (emergency shutter closing button). The opening is closed by releasing and the shutter curtain 5 is naturally lowered by its own weight, so that a predetermined fire prevention section is formed. In this embodiment, in the repeater 30, the control circuit 35a that operates according to the input of the disaster prevention signal BS and the power (for example, direct current) according to the input of the operation signal of the manual closing device 8 (emergency shutter closing button). 24V) is provided independently of each other. The voltage value of the signal may not be 24 V, and the voltage value is determined as appropriate. The manual closing device 8 is provided with a red emergency shutter closing button which is covered with a resin transparent panel (push-break cap) and configured to be operated by pressing the resin transparent panel in an emergency. . The configuration of the manual closing device 8 will be described later.

  A disaster prevention opening / closing body device such as the fire shutter device 10 receives a disaster prevention signal BS (for example, a DC 24V signal) from the disaster prevention interlocking controller 12 in response to a signal from the sensor 11 that senses smoke and heat generated in the event of a fire. In response to the output, it has an automatic closing device 4 for releasing a brake (not shown) connected to the shutter opening / closing device 50. The automatic closing device 4 operates separately by electric power from a power source means such as a commercial power source 9 or a standby power source (battery power source) supplied from the control circuits 35a and 35b of the repeater 30 via different systems. In addition, as a power supply means, in addition to the standby power supply 33 built in the repeater 30, a backup power supply built in the disaster prevention interlocking controller 12 may be used. In addition, when it is not necessary to open and close the shutter curtain 5 at normal time, the opening / closing machine 50 may be configured only by the brake, not by the drive source and the brake.

  Even if it is difficult to supply commercial power to the fire shutter device 10 in the event of a fire, the standby power source built in the repeater 30 or the standby power source built into the interlock controller 12 for disaster prevention is used to input the disaster prevention signal BS. Based on this, the brake 2 of the shutter opening / closing device 50 can be released, and the shutter curtain 5 having a fire-proof structure in the winding state can be lowered by its own weight to automatically close the opening. In an emergency, by operating the manual closing device 8 (emergency shutter closing button), the control circuit 35b is activated and the shutter curtain 5 can be lowered by its own weight.

  The fire shutter device 10 is provided with an obstacle sensing device that detects contact with an obstacle during opening and closing. The obstacle sensing device includes a transmitter 6 provided on the seat plate at the lower end of the shutter curtain 5 and an obstacle sensing control circuit 13 provided in the storage box of the shutter curtain 5 as shown in the figure. The The transmitter 6 transmits the detection signal to the obstacle detection control circuit 13 in a wired or wireless manner when the seat board switch (microswitch) 61 is activated by an obstacle contact with the seat board. At this time, the automatic closing device 4 stops the closing operation of the shutter curtain 5 according to the input of the obstacle detection signal from the obstacle detection control circuit 13 and performs the avoidance operation. Accordingly, when the seat plate comes into contact with an obstacle when the shutter curtain 5 is lowered by its own weight when a fire occurs, the lowering of the weight of the shutter curtain 5 stops and the avoidance operation is performed.

  The control of lowering the dead weight of the fire shutter device 10 is performed by an opening / closing body control system constituted by the repeater 30 and the automatic closing device 4. The repeater 30 controls the power supply to the automatic closing device 4, and the automatic closing device 4 operates in response to the power supply from the repeater 30, releases the open state held by the brake, and releases the shutter. The curtain 5 is naturally lowered by its own weight.

  FIG. 4 is a diagram showing a schematic configuration of a repeater employed in the fire shutter device of FIG. The repeater 30 is supplied with a commercial AC power source (AC 100 [V], AC 200 [V], etc.) 9 from the outside and a standby power source 33 such as a battery serving as a power supply source of a system different from the commercial AC power source 9. Built in. Therefore, the repeater 30 can operate the automatic closing device 4 by the standby power source 33 or the standby power source of the interlock controller 12 even if the commercial AC power source 9 cannot be supplied in an emergency.

  As shown in FIG. 4, the repeater 30 includes a power supply circuit 31, a charging device 32, a standby power supply (storage battery) 33, a power supply switching device 34, and control circuits 35a and 35b. The power supply circuit 31 converts the commercial power supply 9 into a DC 24V signal, supplies a DC voltage to the control circuits 35 a and 35 b via the power supply switching device 34, and supplies power to the charging device 32. The charging device 32 charges the standby power supply (storage battery) 33 using the power from the power supply circuit 31. The standby power source (storage battery) 33 is composed of a lithium ion rechargeable battery or other battery (including a rechargeable type power source that can be used up like a dry battery) and the like, and a DC voltage control circuit via a power source switching device 34 35a and 35b. The power source switching device 34 selectively switches one power source of the power source circuit 31 or the standby power source 33 and connects it to the control circuits 35a and 35b. Note that the rechargeable power source may be replaced with a type of power source that can be used up, such as a dry battery. In this case, charging is not performed, and thus the charging device is disabled or unnecessary. In this case, power supply from a commercial power supply is not necessary if it is not used except for emergency and maintenance inspection.

  Usually, since the power from the commercial power supply 9 is supplied, the DC voltage from the power supply circuit 31 is supplied to the control circuits 35a and 35b. However, the power supply from the commercial power supply 9 is supplied in an emergency such as a fire. When the operation is stopped, the DC voltage from the standby power supply 33 is supplied to the control circuits 35a and 35b. That is, the standby power supply 33 built in the repeater 30 supplies power to the control circuits 35a and 35b even when commercial power is not supplied to the fire prevention shutter device 10 due to some trouble or failure when a fire occurs. It is something that can be done.

  The control circuit 35a outputs an operation signal (DC 24V signal) based on the disaster prevention signal BS input from the sensor 11, and releases the brake 2. The control circuit 35b outputs an operation signal (DC 24V signal) based on the input of the operation signal of the electric manual closing device 8 (emergency shutter closing button), and releases the brake 2. The return switches 36a and 36b forcibly stop the supply of electric power to the automatic closing device 4.

  As described above, since the control circuit 35a can be supplied with power from a commercial power supply or a standby power supply, an operation signal (DC 24V signal) is generated based on the disaster prevention signal BS input from the sensor 11 to the control circuit 35a. By outputting and releasing the brake 2, the shutter curtain 5 of the fire prevention structure in the winding state is lowered by its own weight to automatically close the opening. At this time, even if there is a problem in the disaster prevention signal path or a problem occurs in the control circuit 35a, the electric manual closing device 8 (emergency shutter closing button) is operated, so that Since the operation signal (DC 24V signal) is output from the control circuit 35b having the circuit configuration of, the shutter curtain 5 can be lowered urgently by manual operation. In addition to the one using the electric manual closing device 8, there is one configured to release the brake and lower the shutter curtain only by mechanical operation without using electricity.

  First, the sensor 11 detects a fire. Then, a fire signal is input from the sensor 11 to the disaster prevention interlocking controller 12. The disaster prevention interlock controller 12 outputs a disaster prevention signal BS to the repeater 30. The disaster prevention signal BS is often a single signal of about 10 seconds. Since a continuous operation signal (DC 24V signal) is output from the control circuit 35a of the repeater 30 to the automatic closing device 4, the fire curtain shutter curtain 5 in the winding state is lowered by its own weight, and automatically Close the opening.

  On the other hand, when the electric manual closing device 8 (emergency shutter closing button) is operated and a no-voltage A contact ON signal is output to the control circuit 35b of the repeater 30, the control circuit 35b of the repeater 30 continuously Then, an operation signal (DC 24V signal) is output to the automatic closing device 4, and the shutter curtain 5 of the fire prevention structure in the wound state is lowered by its own weight, and automatically closes the opening. At this time, when the electric manual closing device 8 (emergency shutter closing button) operates by receiving power from the standby power supply 33, the remaining electrical capacity of the standby power supply 33 is low or absent. Since the shutter curtain 5 cannot be lowered by its own weight even if the manual closing device 8 (emergency shutter closing button) is operated, the remaining electric capacity of the standby power source 33 is located adjacent to the manual closing device 8. Is displayed, and a remaining amount display means is provided so that the remaining amount can be easily confirmed. In this embodiment, an LED is provided to control various light emission states of the indicator lamp.

Optionally the detector 11 when a fire signal is generated or manual closure device 8 (emergency shutter closing button) is operated, in the shutter curtain 5 is closing operation, i.e., the shutter curtain 5 is in the descent, the obstacle sense When the intelligent device senses an obstacle, a no-voltage A contact ON signal is inputted from the seat switch 6 to the automatic closing device 4, so that the automatic closing device 4 automatically returns and brakes and the shutter curtain Stop descent of 5. When the obstacle is removed, a no-voltage A-contact OFF signal is input from the seat plate switch 6 to the automatic closing device 4 so that the automatic closing device operates again, the brake is released, and the shutter curtain 5 The descent starts with its own weight, and the descent of the own weight stops when the shutter curtain 5 fully closes the opening. At this time, the operation and release of the brake may be performed in response to the supply of power from the standby power supply 33.

  In this embodiment, the standby power supply 33 built in the repeater 30 enables the disaster prevention signal BS and the manual closing device 8 (emergency shutter closing button) even if the commercial power supply 9 is not supplied to the fireproof shutter device 10 in the event of a fire. Based on the operation signal, the brake 2 can be released, and the shutter curtain 5 having a fire-proof structure in the winding state can be lowered by its own weight to automatically close the opening. However, this standby power source is composed of a lithium ion rechargeable battery and other batteries (including a power source that can be used up like a dry battery as well as a rechargeable battery), and has a long-life life. Therefore, in this embodiment, the electric capacity remaining amount display means 14 of the standby power supply 33 is provided in or near the manual closing device 8 (emergency shutter closing button). This is because since the vicinity of the manual closing device 8 (emergency shutter closing button) is inspected at the time of inspection or the like, the remaining amount can be easily confirmed. 3 and 4, the illustration of the connection relationship of the commercial power supply other than the repeater 30 is omitted.

  5 and 6 are views showing an example of a manual closing device provided with a remaining amount display means. FIG. 5 shows a state in which the lid of the manual closing means 8 is closed, and FIG. It is a figure which shows the state which the lid | cover opened. As shown in the figure, the manual closing device 8 includes a metal casing 51 and a lid 52. The lid 52 has a security key 53 and a resin transparent panel (pull-off cap) 54 that allows an emergency shutter closing button 61 provided inside the housing 51 to be seen from the outside. The resin-made transparent panel 54 is configured to be easily pushed by hand or the like in an emergency. The emergency shutter closing button 61 is a red push button. An open button 62, a close button 63, and a stop button 64 that control opening / closing of the shutter curtain 5 are provided inside the housing 51 of the manual closing device 8. Further, when the emergency shutter closing button 61 is pressed, the shutter curtain 5 is automatically closed, so that the opening / closing control by the opening button 62, the closing button 63, and the stopping button 64 cannot be performed. Therefore, a recovery button 65 for enabling the open / close control by the open button 62, the close button 63, and the stop button 64 is provided above the emergency shutter close button 61.

  The remaining amount display means 14 is composed of an LED, and the LED blinks or lights up to indicate that the electric capacity has decreased. Further, in this embodiment, as shown in FIG. 5, the remaining amount display means 14 can be confirmed from the outside through the transparent panel 54 even when the lid 52 is closed. In addition to this LED, a plurality of battery-shaped display units may be provided, and the display state of the display unit may be changed according to the electric capacity so that the state can be confirmed through the transparent panel 54. In this case, it is possible to determine whether power is supplied from the commercial power source 9 and / or the standby power source by using the commercial power source 9 and / or the standby power source as the power source for operating the remaining amount display means 14. It becomes possible. In addition to the transparent panel configured to operate the emergency shutter closing button 61 indirectly through the transparent panel by pressing the transparent panel in an emergency, the transparent panel operates the emergency shutter closing button. The emergency shutter close button 61 can be directly operated after moving to a place that does not interfere with the operation (turning, removing, sliding along the lid 52, pushing the emergency shutter close button 61 without operating, etc.) A transparent panel may be used.

  FIG. 7 is a flowchart showing an example of the operation of the disaster-prevention opening / closing body device of FIGS. 3 and 4. First, in step S71, it is determined whether or not the sensor signal from the sensor 11 has been received, or whether or not the manual closing device 8 (emergency shutter closing button 61) has been pressed (ON). If it has been pressed or turned on (yes), the process proceeds to the next step S72, and if it has not been received or has not been pressed (no), the determination in step S71 until the signal is received or pressed. Repeat the process.

  In step S72, since the sensor signal is received or the manual closing device 8 (emergency shutter closing button 61) is pressed (ON), the automatic closing device 4 releases the brake. Thereby, in step S53, the shutter curtain 5 starts to descend by its own weight by releasing the brake.

  In step S74, it is determined whether or not an obstacle touches the seat plate at the lower end of the shutter curtain 5 and is detected by the micro switch 61 built in the seat plate. The process proceeds to step S76, and if not detected (no), the process proceeds to step S75.

  In step S75, the descent operation of the shutter curtain 5 is continued, and the process returns to step S74. Note that when the shutter curtain 5 descends and comes into contact with the floor surface or the like and becomes fully closed, further closing cannot be performed. In this case, the processing is stopped. On the other hand, if an obstacle detection signal is output from the microswitch and it is determined yes in step S74, the process proceeds to step S75.

  The determination of “yes” in step S74 means that the seat plate has come into contact with some obstacle during the lowering operation of the shutter curtain 5. Therefore, in step S76, the lowering of the shutter curtain 5 is stopped. The stop here is to apply braking, and the stop state (avoidance operation) is maintained until the brake is released in step S72.

  In step S77, the determination in step S77 is repeated until no obstacle detection signal is continuously sensed from the micro switch 61 built in the seat plate. When no obstacle sense signal is sensed, the process returns to step S72 to return to the brake. Is released and the weight drop is resumed. In this embodiment, as long as the obstacle detection signal is continuously sensed, a flow in which this step S77 cannot be exited is shown.

  In the above-described embodiment, when the obstacle detection signal is no longer sensed, the process returns to step S72. However, in the usage mode in which the descent is prioritized, the predetermined state is maintained even in the sensed state. The process may return to step S72 as time elapses, and the descent may be resumed, or may be lowered by a predetermined distance or lowered for a predetermined time depending on circumstances. Note that after the obstacle detection signal is no longer sensed, the descent may be resumed by returning to step S72 after a predetermined time has elapsed.

  FIG. 8 is a view showing a modified example of the fire shutter device that is a disaster prevention opening / closing device according to the present invention, and FIG. 9 shows a schematic configuration of a modified example of the repeater employed in the fire shutter device of FIG. FIG. The fire shutter device shown in FIG. 3 and FIG. 4 is used to input the operation signal of the control circuit 35a that operates in response to the input of the disaster prevention signal BS and the manual closing device 8 (emergency shutter closing button) in the repeater 30. A control circuit 36a that operates accordingly is provided independently. In this case, if there is a problem in the signal path related to the control open circuit 35b or a problem occurs in the control circuit 35b, the control circuit 35b does not operate even if the emergency shutter closing button (manual closing device) 8 is operated. A condition can occur.

  Therefore, in the modified examples of FIGS. 8 and 9, two series of control circuits 351 and 352 having the same configuration are provided, and the disaster prevention signal BS and the manual closing device 8 (emergency use) are provided in the respective control circuits 351 and 352 in different systems. An operation signal for the shutter close button 61) is input.

In this case, the two standby power sources 331 and 332 may employ different power source systems (power sources such as dry batteries and power sources such as rechargeable lithium ion rechargeable batteries and other batteries) that are different from each other. Good. The power of the standby power supplies 331 and 332 is also supplied to the shutter switch 50 and the remaining amount display means 14. In the figure, the remaining amount display means 14 displays the total remaining amount of the two standby power supplies, but may display the remaining amounts of the two standby power sources 331 and 332 individually. Good. In addition, when the standby power sources 331 and 332 are replaced, they may be replaced alternately at about half the life of the standby power source. That is, when the lifespan of the standby power supplies 331 and 332 is 2 years, the replacement is performed by alternately replacing the standby power supply 331 in the first year and only the backup power supply 332 in the next year. The same effect as that of exchanging a standby power supply with a lifetime of 2 years every year can be obtained. The battery capacity is checked by passing a load current through the battery for 3 seconds and measuring the battery voltage at that time. In FIG. 10, the illustration of the connection relationship of the commercial power supply to other than the repeater 30 is omitted.

  In the above-described embodiment, the case where the remaining amount display means is provided separately from the emergency shutter closing button 61 has been described.

You may make it supply via.

  Further, in the above-described embodiment, the fire shutter device that is closed while the shutter curtain that is the opening and closing member is lowered has been described as an example. However, the opening and closing member is extended by the horizontal pulling method or raised. It can be applied in the same manner even if it is drawn out by a method or drawn out by a horizontal method. In addition, although there are some that are not suitable for fire, an appropriate device may be selected as the open / close body according to the type of disaster prevention, for example, a shutter device, a blind device, a roll screen device, a banner device, or the like. When the opening / closing body device is a shutter device, the opening / closing member, which is the opening / closing body means, is a shutter curtain. Pipe curtains made from one piece, panel curtains made from one or more connected panel materials, net curtains made from net materials, sheet curtains made from synthetic resin or cloth fiber sheet materials, or composite members thereof This is due to the composite curtain. The material of the opening / closing member that is the opening / closing member means may be any material as long as it is suitable for the purpose of use. Specifically, it can be made of metal, wood, plastic, cloth, or a composite of these. In the case of an opening / closing body device installed for the purpose of fire prevention, the material of at least the opening / closing member which is the opening / closing body means preferably has fire resistance.

In the above-described embodiment, an example in which an obstacle is detected by abutting against the obstacle, such as a seat plate switch, has been described as an example, but other obstacles can be detected by a tape switch or non-contact. It may be a thing. For example, as an object that detects an obstacle without contact, an infrared light emitting element and a light receiving element are provided on both sides of the opening / closing member, and the obstacle is detected when the infrared light is blocked. There is. The obstacle detection means detects an obstacle present in the opening including the periphery of the opening.
In the above-described embodiment, the manual closing device 8 (emergency shutter closing button 61), which is an electric manual closing device, has been described as operating by receiving output from the standby power supply 33. However, the manual closing device 8 (emergency shutter closing button 61) may be provided with a dedicated spare power supply separately from the spare power supply 33, and in this case, the remaining power may be displayed.

In the above-described embodiment, the disaster prevention signal BS is described as being input from the interlock controller 12 to the repeater 30, but it may be input from the disaster prevention panel or may be input directly from the sensor. Anyway. In addition, the disaster prevention signal BS may be a perforated voltage signal, such as a DC 24V signal, may it signal der-free voltage. In addition to the automatic closing device, the repeater may supply power to an obstacle detection control circuit or the like as necessary. Similarly, status display means for displaying information other than the fact that the electric capacity of the power supply means has decreased can also be provided at a position that can be seen through a transparent panel that can be pushed through. The remaining amount display means may display the status display other than that the remaining capacity of the electric capacity of the power supply means is reduced by the same display means. Further, the remaining amount display means may receive power necessary for displaying the remaining amount from any one of a commercial power supply, a standby power supply, and other power supply means installed.
