Description

[Technical field]

[0001] The present invention relates to an opening / closing body device configured to separate openings of structural bodies including buildings such as houses, buildings, factories, warehouses, garages, etc., using an opening / closing body such as a shutter, and a power supply method for such an opening / closing body device, and in particular to an opening / closing body device and a power supply method for an opening / closing body device that are 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] In general, an electric opening / closing body device is configured such that an opening / closing body for opening and closing an opening / closing space of a structure such as a building is raised and lowered by an opening / closing machine (motor, etc.) arranged in the ceiling of the structure or in a shutter case. In such an electric opening / closing body device, for example, some are configured such that the opening / closing body itself descends under its own weight and is held in a fully closed state by performing a predetermined operation during a power outage. Therefore, in the past, when opening an opening / closing body in a fully closed state during a power outage, the opening / closing body was manually wound up and opened, for example, by rotating the output rotating shaft (rotating shaft) of the opening / closing machine with a manual operating handle installed nearby.

[0004] Among such electrically operated opening / closing body devices, there is one equipped with an emergency power supply device configured to electrically operate the opening / closing body device to emergency open the opening / closing body by connecting a fire brigade hose to a water inlet (water supply port) and discharging (supplying) water even in the event of a power outage due to a fire. The emergency power supply device is configured by mounting electronic components such as a backup power source consisting of a battery and an inverter device. This emergency power supply device is connected to external devices such as an automatic closing device of the opening / closing body device, an obstacle detection device, a harm prevention interlocking relay, an operation switch with a start button, and a water pressure switch, as well as an external power line. An example of an opening / closing body device equipped with such an emergency power supply device is described in Patent Document 1. In addition, there is also one that uses a generator to supply power to a control device of the opening / closing machine (motor, etc.) during a commercial power outage. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2009-79457 A Summary of the Invention [Problem to be solved by the invention]

[0006] When using the manual operation handle during a commercial power outage, the worker must climb up onto a stepladder or workbench to open the inspection hatch at the top while opening and closing the opening / closing body, which is very troublesome. On the other hand, when an emergency power supply device such as that described in Patent Document 1 is provided, the equipment costs increase and the battery of the backup power supply must be replaced periodically. Or, when a generator is used, the equipment costs increase and maintenance such as refilling the generator with fuel and changing the oil is required.

[0007] The present invention has been made in consideration of the above-mentioned points, and aims to provide an opening / closing body device that can easily operate the opening / closing body even when there is no power supply from the commercial power source, such as during a power outage, without significantly increasing equipment costs or maintenance work. [Means for solving the problem]

[0008] A first feature of the opening / closing body device of the present invention is that it comprises an opening / closing means provided on the peripheral portion of the opening, an opening / closing machine for electrically operating the opening / closing means, a control means for driving the opening / closing machine to electrically control the operation of the opening / closing means, and a power supply means for supplying power to the control means, wherein the power supply means has a first connector connected to a commercial power source and a second connector connected to the first connector, a connection cable connected to the control means, and an external power source cable having a third connector at one end to which the second connector of the connection cable is connected and a fourth connector at the other end to an output terminal of the external power source, and the second connector of the connection cable is connected to the first connector when there is a supply of power from the commercial power source, and when there is no supply of power from the commercial power source, it is removed from the first connector and connected to the third connector of the external power source cable.

[0009] The commercial power source and the control means are connected via a connection cable having a first connector connected to the commercial power source and a second connector connected to the first connector, so that when there is no power supply from the commercial power source, such as during a power outage, the second connector of the connection cable can be easily removed from the first connector connected to the commercial power source. Then, by connecting the removed second connector of the connection cable to the third connector of the external power supply cable, power from the external power supply can be easily supplied to the control means via the external power supply cable and the connection cable. Therefore, the opening and closing body can be easily operated even when there is no power supply from the commercial power source, such as during a power outage, without a significant increase in equipment costs or maintenance work.

[0010] The opening / closing means is composed of an opening / closing member such as a shutter curtain that electrically opens and closes an opening such as an entrance or window, or an internal passage or space in a structure such as a building, such as a house, a building, a factory, a warehouse, or a garage. When the opening / closing means is a shutter curtain, it is stored in the upper part, which is one of the peripheral parts of the opening of a building, etc., and the shutter curtain passes through a lintel or the like and descends, electrically opening and closing the opening. In addition, the opening / closing means may be stored in the lower part of the opening and electrically open and close by an upward movement, or the opening / closing means may be stored in the side and electrically move by a sliding movement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] A preferred embodiment of an opening / closing body device according to the present invention will be described below with reference to the attached drawings. In this embodiment, a shutter device equipped with a shutter curtain that opens and closes vertically as an opening / closing means will be described as an example. Fig. 1 is a diagram showing the schematic configuration of a shutter device, which is an opening / closing body device according to one embodiment of the present invention. In Fig. 1, the opening / closing body device 10 is a shutter device that opens and closes an opening of an entrance and exit vertically.

[0027] The opening / closing body device 10 is provided at an opening of a building, and is basically composed of a shutter case 11, a shutter curtain 12, guide rails 13, 14, a winding shaft 15, a chain 16, a motor 17, a position detector 172 (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 device, 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 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.

[0028] The guide rails 13, 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 guide rails 13, 14 to open and close the opening.

[0029] 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.

[0030] 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.

[0031] In addition, the position detection device 172 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] The obstacle detector 185 has a transmitter provided 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 transmitter of the obstacle detector 185 to the control device 18 is not limited to a wired system as shown in the figure, but 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 guide rails 13 and 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.

[0036] The power supply device 20 is supplied with 100V AC or 200V AC power from the power line AC of the 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.

[0037] The opening / closing body device 10 is installed at or near an opening such as an entrance or window, or an internal passage or space in a structure such as a house, a building, a factory, a warehouse, or a garage, so that vehicles such as electric vehicles can easily approach. Electric vehicles and the like are equipped with a battery and an inverter, and by using AC power obtained by converting the DC power of the battery into AC power, it becomes possible to easily perform the opening / closing operation of the opening / closing body during a power outage without using an emergency power supply device or a generator as described in Patent Document 1.

[0038] Fig. 2 is a diagram for explaining the operation of each device in the shutter device shown in Fig. 1 and an example of the configuration of a power supply device. 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 in Fig. 2, the connection relationship of the commercial power source to devices other than the control device 18 is omitted.

[0039] The power supply device 20 shown by the dashed line in FIG. 2 includes a waterproof plug receptacle 21a (first connector) connected to the power line AC of the commercial power source via the power supply wiring 21, a waterproof plug 22b (second connector) connected to the waterproof plug receptacle 21a, a connection cable 22 connected to the control device 18, an external power source cable 23 having a waterproof plug receptacle 23a (third connector) at one end to which the waterproof plug 22b of the connection cable 22 is connected and a waterproof plug 23b (fourth connector) at the other end connected to the output terminal of the external power source 30, and a circuit breaker 24.

[0040] The waterproof plug receiver 21a, the waterproof plug 22b, the waterproof plug receiver 23a, and the waterproof plug 23b are of waterproof specification, having a waterproof structure that prevents the intrusion of liquid. By using waterproof plug receptacle 21a, waterproof plug 22b, waterproof plug receptacle 23a, and waterproof plug 23b as the first connector, second connector, third connector, and fourth connector, protection is provided against water leakage and dust in the event of a disaster, as well as against everyday condensation and dirt, improving safety and reliability.

[0041] When power is supplied from the commercial power source, the waterproof plug 22b of the connection cable 22 is connected to the waterproof plug receptacle 21a 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 line 21, the waterproof plug receptacle 21a, the waterproof plug 22b, and the connection cable 22.

[0042] 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 21a connected to the commercial power source, and is connected to the waterproof plug receptacle 23a of the external power source cable 23. Then, the waterproof plug 23b of the external power source cable 23 is connected to the output terminal of the external power source 30. As a result, power from the external power source 30 is supplied to the control device 18 via the waterproof plug 23b, the external power source cable 23, the waterproof plug receptacle 23a, the waterproof plug 22b, and the connection cable 22.

[0043] The commercial power source and the control device 18 are connected via a waterproof plug receptacle 21a connected to the commercial power source and a connection cable 22 having a waterproof plug 22b connected to the waterproof plug receptacle 21a. Therefore, 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 can be easily removed from the waterproof plug receptacle 21a connected to the commercial power source. Then, by connecting the removed waterproof plug 22b of the connection cable 22 to the waterproof plug receptacle 23a of the external power supply cable 23, power from the external power supply 30 can be easily supplied to the control device 18 via the external power supply cable 23 and the connection cable 22. Therefore, the opening and closing body can be easily operated even when there is no power supply from the commercial power source, such as during a power outage, without a significant increase in equipment costs or maintenance work.

[0044] The circuit breaker 24 is connected between the waterproof plug 22b of the connection cable 22 and the control device 18, and is connected to a commercial power source or external power supply When the input current from 30 reaches a predetermined cutoff value, an overcurrent is detected and the connection between the commercial power source or external power source 30 and the control device 18 is cut off. A circuit breaker 24 that detects an overcurrent and cuts off the connection is provided between the waterproof plug 22b of the connection cable 22 and the control device 18. When an overcurrent occurs, the circuit breaker 24 cuts off the connection between the commercial power source or external power source 30 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.

[0045] Fig. 3 is a diagram showing another example of the configuration of a power supply device. In a power supply device 20 of this example, a waterproof outlet 21a' is provided as a first connector connected to a commercial power source instead of the waterproof plug receptacle 21a shown in Fig. 2. The other configurations are the same as those of the example shown in Fig. 2.

[0046] When power is being supplied from the commercial power source, the waterproof plug 22b of the connection cable 22 is connected to the waterproof outlet 21a' 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 waterproof outlet 21a', the waterproof plug 22b, and the connection cable 22.

[0047] 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 outlet 21a' and connected to the waterproof plug receptacle 23a of the external power supply cable 23. Then, the waterproof plug 23b of the external power supply cable 23 is connected to the output terminal of the external power supply 30. As a result, power from the external power supply 30 is supplied to the control device 18 via the waterproof plug 23b, the external power supply cable 23, the waterproof plug receptacle 23a, the waterproof plug 22b, and the connection cable 22.

[0048] The commercial power source and the control device 18 are connected via a waterproof outlet 21a' connected to the commercial power source and a connection cable 22 having a waterproof plug 22b connected to the waterproof outlet 21a'. Therefore, 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 can be easily removed from the waterproof outlet 21a' connected to the commercial power source. Then, by connecting the removed waterproof plug 22b of the connection cable 22 to the waterproof plug receptacle 23a of the external power supply cable 23, power from the external power supply 30 can be easily supplied to the control device 18 via the external power supply cable 23 and the connection cable 22. Therefore, the opening and closing body can be easily operated even when there is no power supply from the commercial power source, such as during a power outage, without a significant increase in equipment costs or maintenance work.

[0050] In FIG. 4(a), the power supply device 20 includes a housing 20a having an opening, and a lid (door) 20b that covers the opening of the housing 20a. The housing 20a is installed near the shutter curtain 12, embedded in a wall surface that constitutes an entrance or window of a building that the shutter curtain 12 opens and closes, or protruding from the wall surface. The lid 20b is a one-sided door with a waterproof structure that closes the opening of the housing 20a in a hermetically sealed state. A handle 20c is attached to the lid 20b, and the handle 20c is rotated to lock and unlock the lid. When the handle 20c is rotated and pulled toward the user, the lock is released and the lid 20b is opened, and when the handle 20c is pushed toward the depth of the drawing and rotated in the opposite direction, the lid 20b is closed and locked. A cable passage hole 20d is provided in the lower part of the cover 20b, and a rubber packing 20e is attached in the cable passage hole 20d.

[0051] 4(b), the housing 20a accommodates a waterproof outlet 21a', a connection cable 22, and a circuit breaker 24. A waterproof plug 22b of the connection cable 22 is connected to the waterproof outlet 21a'. When the external power cable 23 is not in use, the external power cable 23 is also stored within the housing 20a.

[0052] When the external power supply cable 23 is not in use, the external power supply cable 23 is stored inside the housing 20a as shown in FIG. 4(b) and the opening of the housing 20a is covered with the lid 20b as shown in FIG. 4(a). This protects the waterproof outlet 21a', the connection cable 22, the external power supply cable 23, and the circuit breaker 24 stored inside the housing 20a from water ingress due to rain leaks and from dirt such as dust, thereby further improving safety and reliability. When necessary, the external power cable 23 can be taken out of the housing 20a and used immediately without the need for a separate power cable.

[0053] FIG. 5(a) is an external view of the power supply device with the lid open and the external power cable in use, and FIG. 5(b) is an external view of the power supply device with the lid closed and the external power cable in use.

[0054] In FIG. 5(a), while the external power cable 23 is in use, the waterproof plug 22b of the connection cable 22 is removed from the waterproof outlet 21a' and connected to the waterproof plug receptacle 23a of the external power cable 23. However, when the lid 20b shown in FIG. 5(a) is in the open state, the open lid 20b may get in the way of operating the opening-closing body device 10, and there is a risk that the operator of the opening-closing body device 10 may come into contact with the open lid 20b and be injured.

[0055] Therefore, as shown in FIG. 5(b), the external power cable 23 is passed through the cable passage hole 20d provided in the lid 20b, and the opening of the housing 20a is covered with the lid 20b, and the lid 20b is completely closed. At this time, a rubber packing 20e provided inside the cable passage hole 20d prevents the surface of the external power supply cable 23 from contacting the edge of the cable passage hole 20, thereby preventing damage to the exterior of the external power supply cable 23. Furthermore, the rubber packing 20e closes the gap between the cable passage hole 20d and the external power supply cable 23, preventing rainwater, dust, and the like from entering the housing 20a.

[0056] By providing a cable passage hole 20d in the lid 20b, passing the external power cable 23 through the cable passage hole 20d, and covering the opening of the housing 20a with the lid 20b, the lid 20b can be completely closed even while the external power cable 23 is in use, so that the open lid 20b does not interfere with the operation of the opening / closing body device 10 and there is no risk of the operator of the opening / closing body device 10 coming into contact with the open lid 20b and being injured.

[0057] FIG. 6(a) is an external view of a power supply device according to another embodiment of the present invention with its lid closed, and FIG. 6(b) is an external view of a power supply device according to another embodiment of the present invention with its lid open. In this embodiment, the cover 20b has a chamfered portion 20f that is rounded to reduce sharpness at the corner of the edge on the open side. The corresponding corner of the opening of the housing 20a is also rounded in the same manner as the chamfered portion 20f. By providing a chamfered portion 20f at the corner of the edge on the open side of the lid 20b, even when the lid 20b is in the open position, the risk of an operator of the opening / closing body device 10 coming into contact with the corner of the open lid 20b and being injured is reduced. In this embodiment, a spring hinge 20g is attached to a support that supports the lid 20b so that it can be opened and closed relative to the housing 20a. A spring that biases the lid 20b in a direction to close the lid 20b is built in the spring hinge 20g. The lid 20b is automatically closed by the action of the spring built in the spring hinge 20g. By attaching a spring hinge 20g to the support part that supports the lid 20b so that it can be opened and closed freely relative to the housing 20a, the lid 20b closes automatically, further reducing the risk of the operator of the opening / closing body device 10 coming into contact with the lid 20b and being injured.

[0058] FIG. 7(a) is a diagram showing an external power cable with a simple instruction manual attached, and FIG. 7(b) is a diagram showing an example of the simple instruction manual. In FIG. 7(a), in this embodiment, a simple instruction manual (quick guide) 40 describing how to use the external power cable 23 and the external power supply 30 is detachably attached to the external power cable 23. In this embodiment, a simple instruction manual 40 is attached to the external power cable 23 by a string 41, and this string 41 is passed through the above-mentioned cable hole 20d when the lid 20b is closed, so that when the lid 20b is closed, the simple instruction manual 40 is positioned at the bottom outside of the housing 20a. Instruction manuals detailing how to operate the equipment related to the opening / closing body device 10 have traditionally been provided in the form of booklets or computer software, but it is desirable to keep these in an easily accessible location in case of emergencies such as power outages. By removably attaching simple instruction manual 40, which describes how to use external power cable 23 and external power source 30, to external power cable 23, it becomes possible to easily use external power source 30 by following the instructions in simple instruction manual 40 when using external power cable 23, without having to refer to a separate detailed instruction manual.

[0059] The simple instruction manual 40 may be attached to the connection cable 22, not limited to the external power supply cable 23. Alternatively, a simple instruction manual describing how to use the waterproof plug 22b of the connection cable 22 may be attached to the connection cable 22 separately. Furthermore, when the external power cable 23 is not in use, the simple instruction manual 40 may be stored together with the external power cable 23 in the housing 20a so that the simple instruction manual can be read after opening the lid 20b. Furthermore, the simple instruction manual 40 may include not only instructions on how to use the external power cable 23 and the external power source 30, but also other information such as necessary precautions and product specifications.

[0060] According to the embodiment described above, it is possible to easily operate an opening / closing device that is normally operated using commercial power even when there is no power supply from the commercial power source, such as during a power outage.

[0061] In addition, the first connector, second connector, third connector, and fourth connector used in the present invention are not limited to the configuration examples of the embodiments described above, and male connectors and female connectors can be used in appropriate combinations.

[0062] The opening / closing body 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. [Explanation of symbols]
