Description

The present invention relates to an opening/closing device that is configured to separate openings in structural bodies, including buildings such as houses, buildings, factories, warehouses, and garages, using opening/closing bodies such as shutters, and in particular to an opening/closing device that is suitable for charging external power sources such as electric vehicles.

Opening and closing body devices such as shutter curtains are installed at the entrances and windows of structural bodies including houses, buildings, factories, warehouses, garages, and other buildings, or at openings such as internal passages and spaces, and the openings are opened and closed by moving the opening and closing body. This opening and closing body device is configured to unfold and lower from the top of the opening an opening and closing body such as a slat curtain made of many rectangular slat materials, a pipe grill curtain made of many pipe materials connected with link materials, a panel curtain made of one panel material or many connected 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, etc., to close the entire opening. In many cases, the opening and closing body of such opening and closing body devices is opened and closed electrically. Examples of electrically operated opening and closing body devices include an electric shutter device, an electric door device, and an electric awning device.

In general, an electric opening/closing body device is configured so that an opening/closing body for raising and lowering the opening/closing space of a structure such as a building is raised and lowered by an opening/closing machine (motor, etc.) installed in the ceiling of the structure or in the shutter case. In such an electric opening/closing body device, for example, some are configured so that the opening/closing body itself will descend under its own weight and be held in a fully closed state by performing a specified 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 rolled 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.

Some of these electrically operated opening/closing devices are equipped with an emergency power supply device that is configured to electrically operate the opening/closing device and open the opening/closing body in an emergency by connecting a fire brigade hose to the water inlet (water supply port) and discharging (supplying) water, even in the event of a power outage caused by a fire. The emergency power supply device is configured with a backup power source consisting of a battery and electronic components such as an inverter device. This emergency power supply device is connected to external devices such as an automatic closing device for 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 are also devices that use a generator to supply power to the control device of the opening/closing machine (motor, etc.) during a commercial power outage.

JP 2009-79457 A

The above-mentioned conventional technology involves opening and closing the opening/closing body manually or using power from an emergency power supply when there is no power supply from the commercial power source, such as during a power outage, but no consideration was given to using the power source of the opening/closing body device itself for other electrical equipment or other facilities.
In particular, electric vehicles have become increasingly popular in recent years, but their batteries need to be charged on a daily basis. Opening and closing devices are installed in or near openings such as entrances and windows, or internal passageways and spaces in structures such as houses, buildings, factories, warehouses, and garages, allowing vehicles such as electric vehicles to easily approach, and there has been a demand to utilize the power source of opening and closing devices, which are often installed in buildings such as garages, to charge the batteries of electric vehicles.

The present invention has been made in consideration of the above points, and aims to provide a highly convenient opening and closing device that can easily charge an external power source such as an electric vehicle.

The first feature of the opening/closing body device of the present invention is that it comprises an opening/closing means provided on the periphery 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, the power supply means having 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 cable having a third connector connected to the first connector at one end and a fourth connector connected to an input terminal of an external power source at the other end, and when the opening/closing means is operated, the second connector of the connection cable is connected to the first connector, and when the external power source is charged, the third connector of the external power cable is connected to the first connector.

When charging the external power source, the third connector of the external power source cable is connected to the first connector connected to the commercial power source, so that power from the commercial power source is supplied to the external power source via the first connector and the external power source cable, thereby easily charging the external power source.
Therefore, a highly convenient opening/closing body device is provided that can be easily charged with an external power source.

The opening and closing means is composed of opening and closing members such as shutter curtains that electrically open and close openings such as entrances and windows, or internal passageways and spaces in structures such as buildings, including houses, buildings, factories, warehouses, and garages. When the opening and closing means is a shutter curtain, it is stored in the upper part, which is one of the peripheral parts of the opening in a building, and the shutter curtain passes through a lintel or the like and descends, electrically opening and closing the opening. In addition, the opening and closing means may be stored in the lower part of the opening and electrically open and close using an upward movement method, or the opening and closing means may be stored in the side and electrically move using a sliding movement method. Also, the opening and closing means may include those that can fully close the opening when closed, and those that cannot.

A second feature of the opening/closing body device of the present invention is that, in the opening/closing body device described in the first feature, the first connector has only one connection port for connecting the second connector of the connection cable or the third connector of the external power supply cable, and when the second connector of the connection cable is removed from the connection port, the third connector of the external power supply cable is connected to the connection port, and also when the third connector of the external power supply cable is removed from the connection port, the second connector of the connection cable is connected to the connection port.
The first connector connected to the commercial power source has only one connection port, and the commercial power source and control means are connected via the first connector and a connection cable having a second connector connected to the first connector, so that when charging an external power source, the second connector of the connection cable can be easily removed from the connection port of the first connector connected to the commercial power source.
Then, by connecting the third connector of the external power supply cable to the connection port of the first connector connected to the commercial power supply, power from the commercial power supply can be easily supplied to the external power supply via the external power supply cable.

A third feature of the opening/closing body device of the present invention is that, in the opening/closing body device described in the first feature, the first connector has two or more connection ports for connecting the second connector of the connection cable or the third connector of the external power supply cable, and the second connector of the connection cable is connected to one connection port, and the third connector of the external power supply cable is connected to the other connection port.
Since the first connector has two or more connection ports, and the second connector of the connection cable can be connected to one connection port while the third connector of the external power supply cable can be connected to the other connection port, there is no need to remove the second connector of the connection cable from one connection port and attach the third connector of the external power supply cable to that connection port, or vice versa, thereby further improving convenience.

A fourth feature of the opening/closing body device of the present invention is that, in the opening/closing body device described in the first, second, or third feature, the first connector, the second connector, the third connector, and the fourth connector are of waterproof specification having a waterproof structure.
By using waterproof connectors for the first connector, the second connector, the third connector, and the fourth connector, protection is provided against water leaks and dust in the event of a disaster, as well as everyday condensation and dirt, thereby improving safety and reliability.

A fifth feature of the opening/closing body device of the present invention is that, in the opening/closing body device described in the first, second, third, or fourth feature, the power supply means is provided between the second connector of the connection cable and the control means, and has a circuit breaker that detects an overcurrent and cuts off the connection.
A circuit breaker that detects an overcurrent and cuts off the connection is provided between the second connector of the connection cable and the control means. When an overcurrent occurs, the circuit breaker cuts off the connection between the commercial power source and the control means. This prevents damage to equipment due to overcurrent even if a short circuit occurs in the power circuit, improving safety.

A sixth feature of the opening/closing body device of the present invention is that, in the opening/closing body device described in the first, second, third, fourth, or fifth feature, the power supply means has an opening and a housing for accommodating the first connector, the connection cable, and the cable for an external power source, and a lid for covering the opening of the housing.
When the external power cable is not in use, the external power cable is stored in the housing and the opening of the housing is covered with a lid, thereby protecting the first connector, the connection cable, and the external power cable stored in the housing from water ingress due to rain leaks and from dirt such as dust, thereby further improving safety and reliability.
When necessary, the device can be used immediately by removing it from the housing without having to prepare an external power cable separately.

A seventh feature of the opening/closing body device of the present invention resides in that, in the opening/closing body device according to the sixth feature, the cover has a cable passage hole for passing an external power supply cable therethrough.
By providing a cable hole in the lid, passing the external power cable through the cable hole, and covering the opening of the housing with the lid, the lid can be completely closed even while the external power cable is in use, the open lid does not interfere with the operation of the opening/closing body device, and there is no risk of an operator of the opening/closing body device coming into contact with the open lid and being injured.

The eighth feature of the opening/closing body device of the present invention is that, in the opening/closing body device described in the sixth or seventh feature, the lid is of a single-opening type and has a rounded chamfered portion at the corner of the edge on the opening side.
Even when the lid is in an open state, the risk of an operator of the opening/closing device coming into contact with a corner of the open lid and being injured is reduced.

A ninth feature of the opening/closing body device of the present invention is that, in the opening/closing body device described in the first, second, third, fourth, fifth, sixth, seventh, or eighth feature, the power supply means has an external power supply cable and a simple instruction manual describing how to use the external power supply.

A preferred embodiment of an opening/closing body device according to the present invention will now be described 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. Figure 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 Figure 1, the opening/closing body device 10 is a shutter device that opens and closes the opening of an entrance and exit vertically.

The opening and closing body device 10 is installed at the 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 detection device 172, a control device 18, an obstacle detector 185, an operation switch 19, and a power supply device 20. Normally, the opening and closing body device 10 drives the motor 17, which is an opening and closing machine, in response to the operation of the operation switch 19 to control opening and closing. Furthermore, in this opening and 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.

The guide rails 13 and 14 are provided on both ends of the building opening 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 and 14, opening and closing the opening.

The winding shaft 15 is rotatably mounted on both ends of the shutter case 11, and winds and unwinds the shutter curtain 12. The chain 16 connects a driving sprocket mounted on the rotating shaft of the motor 17 to a driven sprocket mounted 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 via the chain 16, and when the motor 17 rotates, the winding shaft 15 rotates via the chain 16, controlling the opening and closing of the shutter curtain 12.

The motor 17 is provided with a position detector 172 (see FIG. 2) for detecting its 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 at the opening on the closed side based on the generation status of this pulse.

The position detection device 172 also functions as an upper and lower limit switch, detecting when the lower end of the shutter curtain 12 reaches the upper limit position for winding and also detecting when the lower end of the shutter curtain 12 reaches the lower limit position for unwinding.

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

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, and stopping 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.

The emergency signal BS is a 24V signal 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 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 configured to be a high-temperature bimetal thermostat with an automatic reset type B contact whose contacts are always on and open and turn off when the contacts reach a specified temperature (any temperature between 100 and 300 degrees Celsius), and when the contacts are open, a signal indicating that a fire has occurred may be output as a signal equivalent to the emergency signal BS.

The obstacle detector 185 has a transmitter installed at the lower end (seat plate) of the shutter curtain 12. When an obstacle is detected, the detector 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 returns to its original position due to the removal of the obstacle, a return signal is also transmitted. 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 installed along the height direction of the guide rails 13 and 14 may be pressed by the force of the seat plate moving when the obstacle comes into contact with the seat plate, or a detection signal may be output from the tape switch to the control device 18 via a wire. In addition, a photoelectric tube, LED, or other light emitting/receiving sensor may be provided at the opening, and an obstacle may be detected without contact by image recognition, etc.

The power supply device 20 is supplied with 100V AC or 200V AC power from the commercial power supply line AC, and when there is no power supply from the commercial power supply, such as during a power outage, AC power with the same voltage as the commercial power supply is supplied from an external power supply 30. As the external power supply 30, an electric vehicle or hybrid vehicle, a portable backup AC power supply, etc. can be used.

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

Figure 2 is a diagram explaining the operation of each device in the shutter device shown in Figure 1 and an example of the configuration of a power supply device. The control device 18 controls the motor 17 using power supplied from the power supply device 20, based on signals from the operation switch 19, obstacle sensor 185, and position detection device 172, as well as the emergency signal BS. Note that in Figure 2, the connection relationship of commercial power sources to devices other than the control device 18 is omitted.

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 cable 23 having a waterproof plug 23b (third connector) connected to the waterproof plug receptacle 21a at one end and a waterproof plug receptacle 23a (fourth connector) connected to the input terminal of the external power source 30 at the other end, and a circuit breaker 24.

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

In the power supply device 20 of this example, only one connection port is provided to the waterproof plug receptacle 21a connected to the commercial power source for connecting the waterproof plug 22b of the connection cable 22 or the waterproof plug 23b of the external power cable 23.
When the shutter curtain 12 is operated, the waterproof plug 22b of the connection cable 22 is connected to the waterproof plug receptacle 21a connected to the commercial power supply. This allows power from the commercial power supply 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.

When charging the external power supply 30, the waterproof plug 22b of the connection cable 22 is removed from the waterproof plug receptacle 21a connected to the commercial power supply, and the waterproof plug 23b of the external power supply cable 23 is connected to the waterproof plug receptacle 21a connected to the commercial power supply. The waterproof plug receptacle 23a of the external power supply cable 23 is then connected to the input terminal of the external power supply 30. This causes power from the commercial power supply to be supplied to the external power supply 30 via the power supply line 21, the waterproof plug receptacle 21a, the waterproof plug 23b, the external power supply cable 23, and the waterproof plug receptacle 23a.

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, so that when charging the external power source 30, 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.
The waterproof plug 23b of the external power supply cable 23 is connected to the waterproof plug receptacle 21a connected to the commercial power supply, so that power from the commercial power supply is supplied to the external power supply 30 via the waterproof plug receptacle 21a and the external power supply cable 23, thereby easily charging the external power supply 30.
Therefore, a highly convenient opening/closing body device 10 is provided that allows the external power source 30 to be easily charged.

The circuit breaker 24 is connected between the waterproof plug 22b of the connection cable 22 and the control device 18, and when the input current from the commercial power source reaches a predetermined cut-off value, it detects an overcurrent and cuts off the connection between the commercial power source and the control device 18.
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 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.

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.
In the power supply device 20 of this example, the waterproof outlet 21a' is provided with two (or more) connection ports for connecting the waterproof plug 22b of the connection cable 22 or the waterproof plug 23b of the power cable 23.

The waterproof plug 22b of the connection cable 22 is connected to one of the connection ports of the waterproof outlet 21a'. 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.

When charging the external power source 30, the waterproof plug 23b of the external power cable 23 is connected to the other connection port of the waterproof outlet 21a'. Then, the waterproof plug receptacle 23a of the external power cable 23 is connected to the input terminal of the external power source 30. This allows power from the commercial power source to be supplied to the external power source 30 via the power supply line 21, the waterproof outlet 21a', the waterproof plug 23b, the external power cable 23, and the waterproof plug receptacle 23a.

The waterproof outlet 21a' has two or more connection ports, and the waterproof plug 22b of the connection cable 22 can be connected to one connection port while the waterproof plug 23b of the external power cable 23 can be connected to the other connection port, so there is no need to remove the waterproof plug 22b of the connection cable 22 from one connection port and attach the waterproof plug 23b of the external power cable 23 to that connection port, or vice versa, further improving convenience.

Figure 4(a) is an external view of a power supply device according to one embodiment of the present invention with the lid closed, and Figure 4(b) is an external view of a power supply device according to one embodiment of the present invention with the lid open.

In FIG. 4A, 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 cover 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 cover 20b, and the handle 20c is rotated to lock and unlock the cover. When the handle 20c is rotated and pulled toward the user, the lock is released and the cover 20b is opened, and when the handle 20c is pushed toward the user and rotated in the opposite direction, the cover 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.

4B, 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.

When the external power cable 23 is not in use, the external power 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 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 removed from the housing 20a and used immediately without the need for a separate power cable.

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

In FIG. 5A, when the external power cable 23 is in use, the waterproof plug 23b of the external power cable 23 is connected to the waterproof outlet 21a'.
However, when the lid 20b shown in Figure 5 (a) is in the open state, the open lid 20b may interfere with the operation of 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.

Therefore, as shown in FIG. 5B, 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 in 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 cable 23, preventing rainwater, dust, and the like from entering the housing 20a.

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, and 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.

FIG. 6(a) is an external view of a power supply device according to another embodiment of the present invention with its cover closed, and FIG. 6(b) is an external view of a power supply device according to another embodiment of the present invention with its cover 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, 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, even when the lid 20b is in the open position.
In this embodiment, a spring hinge 20g is attached to a support portion that supports the cover 20b so that it can be opened and closed relative to the housing 20a. A spring that biases the cover 20b in a direction to close the cover 20b is built in the spring hinge 20g. The cover 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.
