Description

[Technical field]

[0001] The present invention relates to an opening / closing body device configured to separate openings in structural bodies including buildings such as houses, buildings, factories, warehouses, and garages using an opening / closing body such as a shutter, and in particular to an opening / closing body device suitable for controlling an electric opening / closing mechanism (motor, etc.) using an external power source to operate the opening / closing body when there is no power supply from commercial power sources, such as during a power outage. [Background technology]

[0002] An opening / closing body device such as a shutter curtain is installed at an opening such as an entrance or window of a structural body including a house, a building, a factory, a warehouse, a garage, or the like, or an internal passage or space, and the opening is opened or closed by moving the opening / closing body. This opening / closing body device is configured to unfold and lower an opening / closing body such as a slat curtain made of many rectangular slat materials, a pipe grill curtain made of many pipe materials connected with a link material, a panel curtain made of a single panel material or a panel material connected with many panels, a net curtain made of a net material, a sheet curtain made of a sheet material made of synthetic resin or cloth fiber, or a composite curtain made of a composite material of these materials, from the top of the opening and closing the entire opening. In such an opening / closing body device, the opening and closing operation of the opening / closing body is often performed electrically. Examples of electrically operated opening / closing body devices include an electric shutter device, an electric door device, and an electric awning device.

[0003] Among such electrically operated opening / closing body devices, there are some that are designed so that even during a power outage, a vehicle equipped with an on-board battery, a portable power source, a generator, or the like can be placed near the opening / closing body device and connected to the opening / closing body device to be used as an external power source. An example of such an opening / closing body device that can use an external power source is described in Patent Document 1. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2022-48828 Summary of the Invention [Problem to be solved by the invention]

[0005] Since most of the main components of the opening / closing body device are arranged inside the structure, if power is to be supplied to the opening / closing body device from an external power source, the connection terminals for the external power source are also provided inside the structure. Patent Document 1 also assumes such a configuration. However, in the case of a small structure such as a warehouse that is not a garage, a typical vehicle such as an electric car cannot be present inside as an external power source, and even if a person owns a generator and can use it as an external power source, he or she usually does not want to bring a generator that emits exhaust gas into the structure. However, the opening / closing body device described in Patent Document 1 could not meet such a demand. If one wants to use the opening / closing body device described in Patent Document 1 using an external power source arranged outside the structure, there is no choice but to find or create an appropriate gap in the structure and use an extension cable or the like.

[0006] The present invention aims to address such problems. That is, it is an object of the present invention to provide an opening / closing body device that can easily operate the opening / closing body by utilizing an external power source disposed outside the structure even when there is no power supply from the commercial power source, such as during a power outage. [Means for solving the problem]

[0007] In order to achieve this object, the technical means according to the present invention comprises at least the following configuration.

[0008] An opening / closing device comprising: an opening / closing means provided on the periphery of an opening in a structure body; an opening / closing machine for electrically operating the opening / closing means; a control means for driving the opening / closing machine and electrically controlling the operation of the opening / closing means; a power supply device for supplying power based on a commercial power source to the control means; and a plug that can be connected to an external power source when the commercial power source is not available, wherein the plug is disposed at least outside the structure body. Effect of the Invention

[0009] By virtue of these characteristics, the present invention provides the following advantageous effects. It is possible to provide an opening / closing body device that can easily operate the opening / closing body by utilizing an external power source placed outside the structure frame, even when there is no power supply from the commercial power source, such as during a power outage.

[Figure 6] 11 is an explanatory diagram showing a power supply device in an opening / closing body device according to a second embodiment of the present invention. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Below, with reference to the attached drawings, a preferred embodiment of the opening and closing body device according to the present invention, in particular, an example of a shutter device equipped with a shutter curtain that opens and closes up and down as an opening and closing means, will be described. The following drawings have been created for the purpose of explanation, and for the sake of clarity, some components that are not necessary for the explanation may not be shown intentionally. In addition, some components may be shown intentionally large or small for the purpose of explanation, and the drawings are not drawn to an exact scale.

[0012] First Embodiment (Overall configuration of the opening / closing device) Fig. 1 is a diagram showing a schematic configuration of a shutter device which is an opening / closing body device according to a first embodiment of the present invention. In Fig. 1, the opening / closing body device 10 is a shutter device which opens and closes the opening of the entrance / exit of a warehouse from above and below. Here, elements arranged inside the warehouse are drawn to the left of the dotted line in the figure, and elements arranged outside the warehouse are drawn to the right of the dotted line in the figure.

[0013] The opening / closing body device 10 is provided at the opening of the warehouse, and basically includes a shutter case 11, a shutter curtain 12, a left guide rail 13, a right guide rail 14, a winding shaft 15, a chain 16, a motor 17, a position detector 172 (not shown, see FIG. 2), a control device 18, an obstacle detector 185, an operation switch 19, and a power supply device 20. Normally, the opening / closing body device 10 drives the motor 17, which is an opening / closing machine, in response to the operation of the operation switch 19 to control opening and closing. Furthermore, in the opening / closing body device 10, the shutter curtain 12 is held in an open state wound up on the winding shaft 15 by a mechanical holding mechanism (not shown), and when an emergency signal BS indicating the occurrence of a fire or the like is input from the outside to the control device 18 in this open state, the holding mechanism releases the open state, and the shutter curtain 12 naturally descends under its own weight to automatically close the opening.

[0014] The left guide rail 13 and the right guide rail 14 are provided on both ends of the opening of the building so as to contact both ends of the shutter curtain 12, and are made of a metal member or an equivalent member having a guide groove with a U-shaped cross section that spans from the lintel to the floor. The shutter curtain 12 rises and falls along the guide grooves of the left guide rail 13 and the right guide rail 14 to open and close the opening.

[0015] The winding shaft 15 is rotatably provided on both ends of the shutter case 11, and winds and unwinds the shutter curtain 12. A chain 16 connects a driving sprocket provided on the rotating shaft of the motor 17 to a driven sprocket provided on the rotating shaft of the winding shaft 15. Therefore, the rotational driving force of the motor 17 is transmitted to the winding shaft 15 side via the chain 16, and when the motor 17 rotates, the winding shaft 15 rotates via the chain 16, thereby controlling the opening and closing operation of the shutter curtain 12.

[0016] The motor 17 is provided with a position detector 172 (see FIG. 2) for detecting the rotational position, i.e., the open / closed position and open / closed state of the shutter curtain 12. This position detector 172 is composed of a pulse generating rotary encoder or the like. A pulse signal corresponding to the rotation of the motor 17 is output to the control device 18, so that the control device 18 calculates the rotational position of the motor 17 and the position of the tip of the shutter curtain 12 on the closing side at the opening based on the generation status of this pulse.

[0017] In addition, the position detection device 172 (not shown) also serves as an upper and lower limit switch, detecting when the lower end of the shutter curtain 12 has reached the upper limit position for winding up, and also detecting when the lower end of the shutter curtain 12 has reached the lower limit position for unwinding.

[0018] The control device 18 is configured as a microcomputer, and is supplied with power from a commercial power source via a power line AC through a power supply device 20. The control device 18 controls the rotation of the motor 17 based on control signals corresponding to the operating states of the operation buttons on an operation switch 19, signals from a position detector 172 provided on the motor 17, signals from the protector, etc., and releases the holding mechanism based on an emergency signal BS.

[0019] The operation switch 19 has an up (open) button 19A, a stop (stop) button 19B, and a down (close) button 19C as control switches corresponding to the opening / closing operations, and outputs a control signal according to the operation state of each of these buttons to the control device 18. Although not shown in Fig. 1, the control device 18 can also be operated by a wireless remote control device.

[0020] The emergency signal BS is a signal of voltage 24 [V] supplied from an external control room in the event of an emergency such as a fire, and is input to a harm prevention interlocking relay (not shown) in the control device 18. In addition to or instead of the input of the emergency signal BS from the outside, a temperature sensor or the like may be provided inside the shutter case 11 near the opening of the lintel, i.e., the part where the shutter curtain 12 rises and falls. This temperature sensor may be composed of a high-temperature bimetal thermostat with an automatic reset type B contact whose contact is always in the on state and opens and turns off when the contact reaches a predetermined temperature (any temperature in the range of 100 to 300 degrees Celsius), and when the contact is open, a signal indicating that a fire has occurred may be output as a signal equivalent to the emergency signal BS.

[0021] The obstacle detector 185 is disposed at the lower end (seat plate) of the shutter curtain 12, and when an obstacle is detected, it transmits a detection signal corresponding to the movement of the built-in seat plate switch to the control device 18, and when the seat plate switch is returned to its original position after the obstacle is removed, it transmits a return signal. The transmission of the signal from the obstacle detector 185 to the control device 18 is not limited to a wired system as shown in the figure, and may be a wireless system that operates using a battery as a power source. In addition, a seat plate switch that moves when an obstacle comes into contact with the lower end of the shutter curtain 12 may be provided, and a tape switch provided along the height direction of the left guide rail 13 and the right guide rail 14 may be pressed by the moving force of the seat plate when the obstacle comes into contact, or a detection signal may be output from the tape switch to the control device 18 via a wire. In addition, a light emitting / receiving sensor such as a photoelectric tube or an LED may be provided at the opening, and an obstacle may be detected without contact by image recognition or the like.

[0022] 1, many elements of the opening / closing body device 10 including the control device 18 are disposed inside the warehouse, whereas the power supply device 20 is disposed outside the warehouse through wiring continuing to the control device 18. The power supply device 20 is supplied with 100V AC or 200V AC power from a power line AC of a commercial power source, and when there is no power supply from the commercial power source, such as during a power outage, AC power of the same voltage as the commercial power source is supplied from an external power source 30. As the external power source 30, an electric vehicle or hybrid vehicle, a portable backup AC power source, or the like is used, and in the first embodiment, an example of using an electric vehicle EV is illustrated.

[0023] Conventionally, in warehouses where electric vehicles are not parked, except for garages, if the power supply device is installed inside the warehouse, there is no option but to prepare a portable generator or portable power source, but in the opening / closing body device 10 according to the first embodiment, the power supply device 20 is installed outside the warehouse, so vehicles such as electric vehicles can easily approach the connection port of the power supply device 20. Electric vehicles and the like are equipped with a battery and an inverter, and can use AC power obtained by converting the battery's DC power into AC, so it is possible to operate the shutter device during a power outage even if there is no portable power source that can be brought into the warehouse.

[0024] (Function block configuration of opening / closing device) Fig. 2 is an explanatory diagram showing the functional blocks of a shutter device which is an opening / closing body device according to a first embodiment of the present invention. An example of the operation of each device in the shutter device and the configuration of a power supply device will be described with reference to Fig. 2. The control device 18 controls the motor 17 based on the signals from the operation switch 19, the obstacle sensor 185 and the position detection device 172, as well as the emergency signal BS, using power supplied from the power supply device 20. Note that Fig. 2 does not show the connection relationship of the commercial power source to devices other than the control device 18.

[0025] The power supply device 20, shown by the dashed line in Figure 2, is composed of a general-purpose waterproof plug receptacle 21a connected to the power line AC of a commercial power source via a power supply wiring 21, a waterproof plug receptacle 21b for driving a shutter, a waterproof plug 22b connected to the waterproof plug receptacle 21b for driving a shutter, and a connection cable 22 that transmits the power received by the waterproof plug 22b to the control device 18 via a circuit breaker 24.

[0026] The general-purpose waterproof plug receptacle 21a, the waterproof plug receptacle 21b for driving the shutter, and the waterproof plug 22b are of waterproof specification, having a waterproof structure that prevents liquid from entering. This provides protection against water leakage and dust in the event of a disaster, as well as against daily condensation and dirt, improving safety and reliability.

[0027] The circuit breaker 24 is connected between the waterproof plug 22b of the connection cable 22 and the control device 18, and detects an overcurrent when the input current from the commercial power source or external power source reaches a predetermined cutoff value, and cuts off the connection between the commercial power source or external power source and the control device 18. This prevents damage to equipment due to an overcurrent even if a short circuit occurs in the power circuit, improving safety. Note that although the circuit breaker 24 is placed outside the warehouse in Fig. 2, it may be configured to be placed inside the warehouse.

[0028] When power is being supplied from a commercial power source, the waterproof plug 22b of the connection cable 22 is connected to the shutter drive waterproof plug receptacle 21b, which is connected to the commercial power source. This allows power from the commercial power source to be supplied to the control device 18 via the power supply wiring 21, the shutter drive waterproof plug receptacle 21b, the waterproof plug 22b, and the connection cable 22. The general-purpose waterproof plug receptacle 21a is used to connect various electrical devices other than the shutter device, and is configured to allow various electrical devices to be used externally with commercial power sources.

[0029] When there is no power supply from the commercial power source, such as during a power outage, the waterproof plug 22b of the connection cable 22 is removed from the waterproof plug receptacle 21b for driving the shutter, which is connected to the commercial power source. Although not shown in this diagram showing the functional block configuration, the connection cable 22 has a sufficient length to allow the waterproof plug 22b to be moved to a position about 2.6 m away from the waterproof plug receptacle, and is normally stored in a wound state within the housing (see also FIG. 3). With the connection cable 22 unwound and pulled out, the external power source 30 is brought close to the power supply device 20, and the waterproof plug 22b is inserted into the plug receptacle of the external power source 30 to connect it. As a result, the power of the external power source 30 is supplied to the control device 18 via the connection cable 22.

[0030] The commercial power source and the control device 18 are simply connected by inserting the waterproof plug 22b into the waterproof plug receptacle 21b for driving the shutter, which is connected to the commercial power source. When the supply of power from the commercial power source is interrupted, such as during a power outage, the waterproof plug 22b can be removed from the waterproof plug receptacle 21b for driving the shutter and connected to the plug receptacle of the external power source 30, so that the power of the external power source 30 can be easily supplied to the control device 18. In this example, the external power source 30 is an electric vehicle EV, but it may also be a plug-in hybrid vehicle or an ordinary vehicle equipped with an inverter and capable of supplying alternating current. Alternatively, an inverter may be connected to a vehicle capable of outputting only direct current to receive power supply. Alternatively, a portable power source may be used instead of a vehicle. According to the opening / closing body device 10 of the first embodiment described above, it is possible to easily operate the opening / closing body when there is no power supply from the commercial power source, even in facilities such as small warehouses where it is not possible to move an electric vehicle inside the structure.

[0031] (Power supply device configuration) FIG. 3 is an explanatory diagram showing a power supply device 20 in an opening / closing body device according to a first embodiment of the present invention, in which FIG. 3(a) is a front view with a door body 25 of the housing removed, and FIG. 3(b) is a front view with the door body 25 closed.

[0032] In FIG. 3(a), the housing of the power supply device 20 contains a general-purpose waterproof plug receptacle 21a, a waterproof plug receptacle 21b for driving the shutter, a waterproof plug 22b connected to the waterproof plug receptacle 21b for driving the shutter, and a connection cable 22 for transmitting the power received by the waterproof plug 22b to the control device 18 via a circuit breaker 24 (not shown). The connection cable 22 is a long cable having a length of about 2.6 m, and is usually stored in such a manner that it extends downward from the waterproof plug 22b and is wound clockwise inside the housing as shown in the figure. At the base side of the connection cable 22, a circuit breaker 24 is disposed at a position on the back side of the drawing that cannot be seen. However, the circuit breaker 24 may be installed inside the warehouse by passing it through a wiring extending inside the warehouse.

[0033] A lock mechanism 22LK is provided in the vicinity of the waterproof plug 22b inserted in the housing of the power supply device 20, to keep the waterproof plug 22b inserted and unable to be removed. The lock mechanism 22LK is configured to be activated by a relay switch connected to a sensor that detects a power interruption when the supply of commercial power is stopped, and the left and right engagement mechanisms shown in the figure are retracted in the disengagement direction. After the power is restored, the switch configuration is such that the left and right engagement mechanisms engage with the waterproof plug 22b from the left and right after the waterproof plug 22b is inserted. By adopting such a configuration, it is possible to prevent mischief such as intentionally disconnecting the waterproof plug 22b to prevent the opening / closing body device 10 from operating by anyone other than a family member.

[0034] As described above, when the supply of power from the commercial power source is interrupted, such as during a power outage, the lock mechanism 22LK is released, making it possible to remove the waterproof plug 22b from the shutter drive waterproof plug receiver 21b.

[0035] At appropriate locations on the power supply device 20, a display LB1 showing how to insert and remove the plug, a display LB2 showing how to use the external power source, and a display LB3 showing other precautions are provided, forming a simple instruction manual showing the procedures and precautions to be taken in the event of a power outage. The operator who sees the display LB1 will first remove the waterproof plug 22b and unwind the connection cable 22, and then, looking at the display LB2, will realize that all he or she needs to do is insert the waterproof plug 22b into the electric vehicle EV or portable power source. In addition, the operator can be sufficiently alerted to the fact that he or she should not touch the waterproof plug 22b with wet hands and to be careful of electric shock. In this way, if the waterproof plug 22b is connected to the plug socket of the external power source 30 according to the operating procedure, the power of the external power source 30 will be supplied to the control device 18, and the shutter device can be operated even during a power outage.

[0036] As shown in Fig. 3(b), the power supply device 20 is normally covered by a door 25. The door 25 may be pivoted to the housing so that it can be opened and closed freely, or it may be detachable, but the former is more convenient as it prevents parts from being lost. In either case, it is preferable to provide a locking mechanism to prevent tampering, and Fig. 3(b) shows a keyhole 26 for the locking mechanism. However, as mentioned above, the power supply device 20 is provided with a locking mechanism 22LK for preventing the waterproof plug 22b from being removed at all times, so a locking mechanism is not necessary. However, if a locking mechanism is not provided, it is preferable not to provide a general-purpose waterproof plug receptacle 21a from the viewpoint of preventing electricity theft.

[0037] Some may say that it is easy to configure an external power source to be used outside the structure, but it is not appropriate to reject it based on such general statements. If the configuration simply replaces the internal configuration of the building with the external configuration, it may be judged to be easy, but such a configuration is merely a technology that does not take any measures and does not pay attention to the problems that may be problematic in practical use. In this respect, the power supply device 20 in the opening / closing body device according to the first embodiment of the present invention adopts various advantageous configurations after considering the problems that may be problematic in practical use. This is true of a configuration that allows connection switching without using a separate part by simply replacing the plug, and a configuration that ensures safety by allowing the connection to the commercial power source to be switched to the external power source only under specific conditions.

[0038] Second Embodiment (Overall configuration of the opening / closing device) Fig. 4 is a diagram showing a schematic configuration of a shutter device which is an opening / closing body device according to a second embodiment of the present invention. In Fig. 4, the opening / closing body device 10A is a shutter device which opens and closes the opening of the garage doorway from above to below. Here, elements arranged inside the garage are drawn to the left of the dotted line in the figure, and elements arranged outside the garage are drawn to the right of the dotted line in the figure.

[0039] The opening / closing body device 10A is provided at the opening of a garage, and basically includes a shutter case 11, a shutter curtain 12, a left guide rail 13, a right guide rail 14, a winding shaft 15, a chain 16, a motor 17, a position detection device 172 (not shown, see FIG. 5), a control device 18, an obstacle sensor 185, an operation switch 19, and a power supply device 20A, etc. Each of these components as electrical equipment of the opening / closing body device 10A is substantially the same as the opening / closing body device 10 of the first embodiment, so detailed explanations will be omitted.

[0040] The difference between the two configurations is that the power supply device 20A is installed inside and that the emergency signal BS is not input. As mentioned above, the opening / closing body device according to the second embodiment is a garage shutter device. In the case of a warehouse, no automobile vehicle is placed inside, but in a garage, automobile vehicles are placed inside, and it is more common for automobiles to be present inside. In the event of a power outage, it is not desirable for the power supply to the shutter device to be cut off and for automobiles to be unable to be taken out, and in response to this requirement, the power supply device 20A, which also allows power supply from an external power source, is installed inside the garage. In addition, the emergency signal BS is not provided due to the following required specifications. That is, unlike a warehouse, whose shutters are often open during the day, a garage usually has its shutters closed except when cars are entering or leaving the garage, so there is no need to input the emergency signal BS.

[0041] In the case of a garage, is it enough to have the power supply device 20A installed inside? In fact, this is not the case. In the event of a power outage, even if you connect to an external power source to open the shutter device and close the shutter device after the car leaves the garage, it is impossible or difficult to connect the external power source to the power supply device 20A installed inside. In the current situation, the shutter device must be left open until the driver has finished his business outside and returned home, or if he really wanted to close the shutter device, he had to extend an extension cable from the garage window to secure a wiring connection to the car outside the garage. This was very inconvenient.

[0042] Therefore, in the opening / closing body device 10A of the second embodiment of the present invention, in addition to the power supply device 20A arranged inside the garage, a connecting wiring is extended to the outside of the garage, and a second waterproof plug that can be connected to an external power source 30 is provided at the end of the connecting wiring.

[0043] (Function block configuration of opening / closing device) Fig. 5 is an explanatory diagram showing the functional blocks of a shutter device which is an opening / closing body device according to a second embodiment of the present invention. An example of the operation of each device in the shutter device and the configuration of a power supply device will be described with reference to Fig. 5. The control device 18 controls the motor 17 based on signals from the operation switch 19, the obstacle sensor 185 and the position detection device 172 using power supplied from the power supply device 20A. Note that Fig. 5 omits the connection relationship of the commercial power source to devices other than the control device 18.

[0044] The power supply device 20A shown by the dashed line in Fig. 5 is configured to include a shutter drive waterproof plug receptacle 21b connected to the power line AC of the commercial power source via a power supply wiring 21, a waterproof plug 22b connected to the shutter drive waterproof plug receptacle 21b, a connection cable 22 that transmits the power received by the waterproof plug 22b to the control device 18 via a circuit breaker 24, and a power supply / reception switching plug receptacle 21c. As described above and as shown in Fig. 5, the power supply device 20A is disposed inside the structure frame, and an external connection cable 23 with an internal waterproof plug 23c and an external waterproof plug 23d at both ends is installed as an accessory of the power supply device 20A from inside the garage to outside the garage through the wall of the structure frame or the like.

[0045] The shutter drive waterproof plug receptacle 21b, the power supply / reception switching plug receptacle 21c, the waterproof plug 22b, the internal waterproof plug 23c, and the external waterproof plug 23d are all waterproof, with a waterproof structure that prevents liquid from entering. This provides protection against water leakage and dust in the event of a disaster, as well as against everyday condensation and dirt, improving safety and reliability.

[0046] The circuit breaker 24 is connected between the waterproof plug 22b of the connection cable 22 and the control device 18, and detects an overcurrent when the input current from the commercial power supply or the external power supply reaches a predetermined cutoff value, and cuts off the connection between the commercial power supply or the external power supply and the control device 18. This prevents damage to the equipment due to an overcurrent even if a short circuit occurs in the power circuit, improving safety. Although the circuit breaker 24 is depicted inside the power supply device 20A in FIG. 5, this is merely meant as one element constituting the power supply device 20A, and the circuit breaker 24 may be physically arranged outside the housing of the power supply device 20A.

[0047] When power is supplied from a commercial power source, the waterproof plug 22b of the connection cable 22 is connected to the shutter drive waterproof plug receptacle 21b connected to the commercial power source. As a result, power from the commercial power source is supplied to the control device 18 via the power supply wiring 21, the shutter drive waterproof plug receptacle 21b, the waterproof plug 22b, and the connection cable 22. The power supply / reception switching plug receptacle 21c normally functions as a connection port for the supply line and connects various electrical devices other than the shutter device, so that various electrical devices can be used inside the garage using the commercial power source. On the other hand, during a power outage, the relay switch 21cs detects a power outage and operates, so that the power supply / reception switching plug receptacle 21c functions as a connection port for the receiving line and supplies power from the external power source 30 to the shutter drive waterproof plug receptacle 21b.

[0048] When there is no power supply from the commercial power source, such as during a power outage, the waterproof plug 22b of the connection cable 22 is removed from the shutter drive waterproof plug receptacle 21b connected to the commercial power source. Although not shown in this diagram showing the functional block configuration, the connection cable 22 has a sufficient length to allow the waterproof plug 22b to be moved to a position approximately 2.6 m away from the shutter drive waterproof plug receptacle 21b, and is normally stored in a wound state within the housing (see also FIG. 6). After unwinding the connection cable 22 and pulling it out, the waterproof plug 22b is inserted into the plug receptacle of the electric vehicle EV parked in the garage to connect it. As a result, power from the electric vehicle EV as the external power source 30 is supplied to the control device 18 via the connection cable 22.

[0049] The commercial power source and the control device 18 are simply connected by inserting the waterproof plug 22b into the waterproof plug receptacle 21b for driving the shutter, which is connected to the commercial power source. When the supply of power from the commercial power source is interrupted, for example during a power outage, the waterproof plug 22b can be removed from the waterproof plug receptacle 21b for driving the shutter and connected to the plug receptacle of the external power source 30, so that the power of the external power source 30 can be easily supplied to the control device 18. In this example, the external power source 30 is an electric vehicle EV, but it may also be a plug-in hybrid vehicle or an ordinary vehicle equipped with an inverter and capable of supplying alternating current. Alternatively, an inverter may be connected to a vehicle capable of outputting only direct current to receive power supply.

[0050] After the shutter device is opened and the electric vehicle EV is taken out of the garage, the external connection cable 23 and the external waterproof plug 23d housed in a case (not shown) provided outside the garage are removed and reconnected to the electric vehicle EV to receive power from the external power source 30, and the shutter device is closed. According to the opening / closing body device 10A according to the second embodiment described above, when the electric vehicle EV is present inside the garage, the connection of the power supply device 20A arranged inside the garage can be switched to the electric vehicle EV, and the shutter device can be opened. After the electric vehicle EV leaves the garage, the external waterproof plug 23d present outside the garage can be connected to the electric vehicle EV, and the shutter device can be closed. This makes it possible to avoid the undesirable situation in which the shutter had to be kept open until the vehicle returned home.

[0051] (Power supply device configuration) FIG. 6 is an explanatory diagram showing a power supply device 20A in an opening / closing body device according to a second embodiment of the present invention, in which FIG. 6(a) is a front view with a door body 25 of the housing removed, and FIG. 6(b) is a front view with the door body 25 closed.

[0052] In FIG. 6(a), the housing of the power supply device 20A contains a power supply / reception switching plug receptacle 21c, a waterproof plug receptacle 21b for driving the shutter, a waterproof plug 22b connected to the waterproof plug receptacle 21b for driving the shutter, and a connection cable 22 for transmitting the power received by the waterproof plug 22b to the control device 18 via a circuit breaker 24 (not shown). The connection cable 22 is a long cable having a length of about 2.6 m, and is usually stored in such a manner that it extends downward from the waterproof plug 22b and is wound clockwise inside the housing as shown in the figure. At the base side of the connection cable 22, a circuit breaker 24 is disposed at a position on the back side of the drawing that cannot be seen. However, the circuit breaker 24 can also be disposed outside the housing of the power supply device 20A.

[0053] The opening / closing body device 10A of the second embodiment is used inside a building and is therefore unlikely to be tampered with, and therefore does not have the locking mechanism provided in the first embodiment, but of course a locking mechanism may be provided. Instead, in the second embodiment, a relay switch 21cs connected to a sensor that detects a power interruption when the supply of commercial power is stopped is configured to switch the current flow path from the power supply / reception switching plug receptacle 21c. As a result, the power supply / reception switching plug receptacle 21c normally functions as a connection port for the supply line, and during a power outage, functions as a connection port for the receiving line.

[0054] At appropriate locations on the power supply device 20A, there are provided a sign LB1 showing how to insert and remove the plug, a sign LB2 showing how to use the external power source, and a sign LB3 showing other precautions, forming a simple instruction manual showing the procedures and precautions to be taken in the event of a power outage. After seeing the sign LB1, an operator will first remove the waterproof plug 22b and unwind the connection cable 22, and then, looking at the sign LB2, will realize that all he or she needs to do is insert the waterproof plug 22b into the electric vehicle EV or portable power source. In addition, it is possible to sufficiently draw attention to the fact that the operator should not touch the device with wet hands and to be careful of electric shock.

[0055] By connecting the waterproof plug 22b to the plug receptacle of the external power source 30 according to the operating procedure, power from the external power source 30 is supplied to the control device 18, making it possible to open the shutter device even during a power outage. After opening the shutter device and leaving the electric vehicle EV, the waterproof plug 22b is inserted again into the shutter drive waterproof plug receptacle 21b. Next, the internal waterproof plug 23c, the wiring of which extends to the outside, is inserted into the power supply / reception switching plug receptacle 21c. Thereafter, by inserting the external waterproof plug 23d into the receptacle of the electric vehicle EV parked outside the garage, it becomes possible to close the shutter device by receiving power supply from the external power source 30 located outside the garage.

[0056] As shown in Fig. 6(b), the power supply device 20A is normally covered with a door 25. The door 25 may be pivoted to the housing so that it can be opened and closed freely, or it may be detachable, but the former is more convenient as it prevents parts from being lost. Although not particularly necessary because it is inside a garage, a keyhole 26 for a locking mechanism is shown in Fig. 6(b).

[0057] (Modification) In the second embodiment, the power supply line from outside the garage is established by inserting the internal waterproof plug 23c into the power supply / reception switching plug receptacle 21c, but the wiring from outside the garage may be constantly connected. However, a situation in which the power line to the outside is connected even when it is not needed and not during a power outage is undesirable in consideration of vandalism, lightning strikes, etc., and it can be said that a mode in which the power line is switched by inserting a plug is more preferable.

[0058] According to each of the embodiments described above, it is possible to receive emergency power supply from outside the structure body, or to receive emergency power supply from both inside and outside the structure body, which is extremely useful in practical use.

[0059] The opening / closing device of the present invention can be applied to, for example, shutter devices, window shutter devices, blind devices, roller screen devices, curtain devices, movable partition devices, sliding door devices, swing door devices, folding door devices, gate devices, awning devices, waterproof board devices, etc.
