Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a building opening / closing device that opens and closes a building opening, and can be applied to, for example, a shutter, a door, an overhead door, a blind, a roll screen, and the like.
[0002]
[Prior art]
For example, the fire-proof shutter functions to prevent the spread of fire and the like by activating a closing operation upon detection of high heat, smoke, or the like accompanying a fire.
[0003]
In recent years, various types of shutters that can be opened and closed by remote control have been applied.
[0004]
[Problems to be solved by the invention]
In the case of a fire shutter, it automatically descends upon detection of high heat or smoke associated with a fire. When such an automatic descent is performed, the fire shutter starts to operate suddenly from the viewpoint of a person in the vicinity of the fire shutter, and is often confused and surprised. Even if the fire prevention system reports the occurrence of a fire throughout the building by its broadcast function, the sudden operation of the fire shutter is a big surprise for people in the vicinity of the fire shutter.
[0005]
Also, in a shutter that can be operated remotely, the operator of the remote controller can naturally recognize the start of the shutter opening or closing operation, but if there is a person in the vicinity of the shutter other than the operator of the remote controller, the shutter suddenly operates. Due to the operation, the surprised confusion of the person is great. For example, in a garage shutter, when a driver gives an instruction for opening from the road side by remote control operation, if there are other people in the garage, the people in the garage are greatly confused.
[0006]
Further, for example, even when the fire shutter is closed, the response of the person in the vicinity thereof varies depending on the area of the opening that is not closed by the shutter. For example, if it is immediately after starting the closing operation, the area of the opening is sufficiently secured so that a person can pass through the shutter, but the opening that allows a person to pass sufficiently just before entering the fully closed state This area is not secured, and heads for an evacuation route that does not pass through the shutter. All of these things are judged by the person in the vicinity of the shutter. However, the shutter closing operation patterns are diversified, and there is a possibility that the judgment is wrong.
[0007]
Furthermore, even if there is a person in the range where the shutter can be seen, the person may be crazy about some kind of operation, etc., and may not notice that the shutter is closing or the shutter is opening. .
[0008]
The present invention has been made in consideration of the above points, and an object of the present invention is to propose a building opening / closing device having a function of providing information to surrounding people when the opening / closing body is activated.
[0009]
[Means for Solving the Problems]
  To solve this problem,BookThe opening / closing device for a building opening according to the invention has an opening / closing body that closes the building opening, and an operation in which the opening / closing body closes the building opening in an open state from the ceiling surface side to the floor surface side,By receiving a disaster prevention signalFrom the time when the opening / closing body operation state detection means and the opening / closing body operation state detection means detect immediately after the closing operation activation means to be started, and immediately after the closing operation of the opening / closing body is started, Period during which the opening / closing body is closedThe period during which detection by the opening / closing body operating state detection means continues, Which performs a display operation appealing to human senses, is provided in the vicinity of the opening of the building and 20-30 cm lower than the ceiling surfaceConfigured as an independent unit with power supplyDisplay meansThe opening / closing body operating state detecting means detects the start of the closing operation of the opening / closing body by causing the end of the opening / closing body in the closing direction to swing the arm of the upper limit switch, and the upper limit switch continues thereafter. The detection state continues even during the closing operation period when the operation state is takenIt is characterized by.
[0010]
  Both the first and second inventions described aboveBy the display operation of the display means, people around the opening / closing device for the building opening can know the information that the display means.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
(A) One embodiment
Hereinafter, an embodiment in which the opening / closing device for a building opening according to the present invention is applied to a fire shutter will be described in detail with reference to the drawings. The fire shutter of this embodiment is a slat shutter.
[0012]
Here, FIG. 1 is a schematic configuration diagram showing the configuration of the fire shutter of this embodiment.
[0013]
In FIG. 1, the fire shutter 1 of this embodiment is guided by a pair of guide rails 2a and 2b provided to extend vertically on both sides of the building opening, and the pair of guide rails 2a and 2b. And a moving slat 3. A space above the ceiling surface is a storage space 4 for storing the slats 3 in an open state of the building opening. Note that a storage box for storing the slats 3 and the like in the lower part of the ceiling surface may be provided instead of the storage space.
[0014]
In the accommodation space 4, the slat 3 is wound in the open state, and the winding shaft 5 from which the slat 3 is pulled out during the closing operation, the opening / closing device 6 that generates at least the driving force in the closing operation, and the driving of the opening / closing device 6 Power transmission mechanism (for example, sprocket and chain) 7 that transmits force to the take-up shaft 5 and automatic closing that activates the generation of driving force for the closing mechanism 6 in response to an external disaster prevention signal A device 8 is provided.
[0015]
Note that the movement of the slat 3 from the closed state to the open state may also be due to the driving force of the opening / closing device 6 and may be a manual type although not shown. In addition, the closing operation is not performed by the opening / closing device 6 generating a driving force, but the opening / closing device 6 releases the position locking mechanism when the slat 3 is opened, and the elastic force such as the weight of the slat 3 or a spring is used. It may be closed.
[0016]
The above-mentioned disaster prevention signal is a signal for starting the disaster prevention operation, and may be output by an individual smoke detector or a high heat detector corresponding to the fire shutter 1 or the disaster prevention of the entire building. The information may be output by a central monitoring center that manages
[0017]
In the case of the fire shutter 1 of this embodiment, in addition to the same components as in the prior art, the following components are further provided.
[0018]
That is, the fire shutter 1 of this embodiment includes a slat operation state detection unit 9 and a display device 10.
[0019]
In the case of this embodiment, the slat operation state detection unit 9 detects the start of the closing operation and the end of the closing operation.
[0020]
As a configuration for detecting the activation of the closing operation (see reference numeral 9a in FIG. 2), a limit switch (upper limit switch) that detects the activation of the closing operation by swinging the arm by a seat plate 3a provided at the lower part of the slat 3 is used. ), A switch interlocking type limit switch that detects the start of rotation of the switch 6, and a photoelectric that detects the start of the closing operation by detecting reflected light from a reflecting plate provided at an appropriate position of the slat 3. A switch can be applied. In these cases, the activation of the closing operation is detected immediately after the closing operation is started. In addition, as a detection configuration of the activation of the closing operation, the above-described recognition of the reception of the disaster prevention signal from the outside as the activation of the closing operation, or from the reception time of the disaster prevention signal from the outside described above until the transition to the closing operation A system that recognizes the start of the closing operation by measuring a predetermined time such as the required time can also be applied.
[0021]
As a configuration for detecting the end of the closing operation (see reference numeral 9b in FIG. 2), the end of the closing operation is detected by the arm swinging by a projecting piece provided at an appropriate position of the slat 3 immediately before the closing state. Closed by detecting the reflected light from the limit switch (lower limit switch) to be operated, the switch interlocking type limit switch to detect the end of rotation of the switch 6, and the reflection plate provided at an appropriate position of the slat 3 A photoelectric switch that detects the end of the operation can be applied. In these cases, the end of the closing operation is detected immediately before the closing operation is ended. In addition, as a detection configuration of the end of the closing operation, one that recognizes the end of the closing operation by measuring a predetermined time longer than the closing operation time from the reception point of the disaster prevention signal from the outside described above can be applied.
[0022]
If a limit switch or the like for managing the position of the slat 3 is already provided, it may be used as a component of the slat operation state detection unit 9.
[0023]
FIG. 2 is a block diagram illustrating an example of a specific configuration of the slat motion state detection unit 9.
[0024]
The slat operation state detection unit 9 in this example includes an upper limit switch 9a and a lower limit switch 9b. The upper limit switch 9a and the lower limit switch 9b are respectively a non-operating selection terminal a selected when the limit switch is not operated, an operating selection terminal b selected when the limit switch is operated, and a common terminal c. It is what has.
[0025]
The common terminal c of the upper limit switch 9a is connected to the display device 10 through the signal line 9c. The common terminal c of the upper limit switch 9a is connected to the non-operating selection terminal a when the limit switch 9a is inactive, and is connected to the operating selection terminal b when the limit switch 9a is activated. The
[0026]
The upper limit switch 9a in this example continuously operates after detecting the closing activation of the slat 3.
[0027]
A common terminal c of the lower limit switch 9b is connected to the display device 10 through a signal line 9d. The common terminal c of the lower limit switch 9b is connected to the non-operating selection terminal a when the limit switch 9b is inactive, and is connected to the operating selection terminal b when the limit switch 9b is activated. The
[0028]
The lower limit switch 9b in this example is continuously operated after detecting the full closure of the slat 3 (or just before the full closure).
[0029]
Further, the selection terminal b when the upper limit switch 9a is activated and the selection terminal a when the lower limit switch 9b is not activated are always connected via the signal line 9e, while the selection terminal when the upper limit switch 9a is not activated. Each of a and the selection terminal b when the lower limit switch 9b is operated is always an open terminal.
[0030]
That is, in the example slat motion state detection unit 9 shown in FIG. 2, after the upper limit switch 9a detects the closing activation of the slat 3, the lower limit switch 9b is fully closed (or immediately before the full closing). The loop consisting of the signal line 9c, the upper limit switch 9a, the signal line 9e, the lower limit switch 9b, and the signal line 9d is configured until the signal is detected. It can be detected whether or not a loop is formed. In other words, the display device 10 can detect the closed activation of the slat 3 (the start of conduction of the current path) and the total closure of the slat 3 (the interruption of the current path that has been conducted). In other words, the conduction period substantially coincides with the closing operation period.
[0031]
The display device 10 performs an information providing operation (display operation) for a person in the vicinity of the fire shutter 1 by receiving a detection signal from the slat operation state detection unit 9.
[0032]
The display device 10 is provided, for example, on a wall surface in the vicinity of one of the guide rails 2a or 2b so that the information providing operation is reliably performed. Moreover, it is preferable to provide the display apparatus 10 in a position about 20 cm to 30 cm lower than the ceiling surface so that a normal consumer who passes through the opening of the fire shutter 1 appropriately does not touch it unnecessarily. For example, the display device 10 is preferably in the shape of a box having a length and width of 10 cm × 10 cm and a depth of several centimeters. Considering the point that the presence is not conspicuous so as not to be a target of mischief, and the function can be sufficiently exhibited when the information providing operation (display operation) is necessary, the above-described physical size is preferable.
[0033]
A signal line (wiring) 11 (in the example of FIG. 2 described above, the signal lines 9c and 9d) connecting the slat operation state detection unit 9 and the display device 10 is formed as a metal molding on the wall surface. This is because there are advantages in the following points compared to the resin molding. More protection of internal wiring against fire flames. High resistance to external impact and little change with time. Good appearance due to metallic luster. In addition, in the fire prevention shutter installed in the school, a metal mall is preferable also in this respect in consideration of mischief by children and students.
[0034]
As shown in FIG. 1, the display device 10 electrically includes a display unit 20 and a power supply unit 30. The display unit 20 is a part that performs a display operation, and the power supply unit 30 supplies an operation power for the display unit 30 to perform a display operation.
[0035]
FIG. 3 is a block diagram showing an example of a detailed configuration of the display unit 20 in the fire shutter 1 of this embodiment.
[0036]
In the configuration example illustrated in FIG. 3, the display unit 20 includes an input detection unit 21, an operation control unit 22, a lamp 23, a voice synthesis unit 24, a speaker (SP) 25, an operation permission / prohibition command unit 26, and the like. .
[0037]
The input detection unit 21 receives a detection signal from the slat operation state detection unit 9 and gives it to the operation control unit 22. If the slat operation state detection unit 9 has, for example, the configuration example shown in FIG. 2 described above, the input detection unit 21 activates the closing of the slat 3 when detecting the start of conduction of the current path. When the interruption of the current path that has been conducted is detected, the operation control unit 22 is notified that the slat 3 is fully closed (or that it is immediately before the full closure).
[0038]
The operation permission / prohibition command unit 26 is set to permit or prohibit the information providing operation (display operation) for the person in the vicinity of the fire shutter 1, and the setting contents The signal is given to the operation control unit 22.
[0039]
The operation permission / prohibition command unit 26 is, for example, a toggle switch, and the person who operates the operation permission / prohibition command unit 26 in the position state of the toggle switch confirms whether the display operation is permitted or the display operation is prohibited. it can. In addition, a push switch, a push push switch, or the like can be applied as the operation permission / prohibition command unit 26. In this case, as a component of the operation permission / prohibition command unit 26, whether the setting state is the display operation permission state or not. It is preferable to provide a light emitting element for distinguishing whether the display operation is prohibited.
[0040]
The operation permission / prohibition command unit 26 is set to a display operation prohibited state when the maintenance person checks the descent of the slat 3 of the fire shutter 1 and the display operation is performed in the building. In other cases, the power supply unit 30 is prevented from having a wasteful power consumption (effective when the power supply unit 30 is a battery). The display operation is allowed to be performed in accordance with the closing operation that is set in the display operation permission state and activated when the true disaster prevention signal is generated. It is preferable to apply a toggle switch or provide a light emitting element as described above so that it can be confirmed that the display operation is permitted to be restored after the maintenance operation is performed with the display operation prohibited state set. . If the display operation is also confirmed during maintenance inspection, the display operation permission state may be set continuously.
[0041]
Further, after setting the operation permission / prohibition command unit 26 to the display operation prohibition state, returning to the display operation permission state means returning the display device 10 to an initial state in which the display operation can be performed. For example, if the operation permission / prohibition command unit 26 is set to the display operation prohibited state while the display operation is being executed, the display operation is stopped. If predetermined display conditions are met, the display operation is performed again from the beginning.
[0042]
The operation control unit 22 includes, for example, a CPU and a ROM, and controls whether or not the display operation is performed. The operation control unit 22 does not execute the display operation regardless of the detection state of the input detection unit 21 when the display operation prohibition state is set by the operation permission / prohibition command unit 26. On the other hand, when the display operation permission state is set by the operation permission / prohibition command unit 26, the operation control unit 22 performs the display operation at least during the closing operation of the slat 3 according to the detection state of the input detection unit 21. Is to execute.
[0043]
The lamp 23 performs a visual display operation under the control of the operation control unit 22. As the lamp 23, for example, it is possible to apply a rotating lamp that emits light and seems to rotate, and has a high alerting power by lighting. Further, as the lamp 23, a lamp that can only be turned on or off can be applied. In this case, flashing (repetition of turning on or off) is more attention to the surrounding people than lighting it during the display operation period. Is preferable because of its high arousal power.
[0044]
The voice synthesizer 24 gives a voice signal related to a predetermined message to the speaker 25 during the display operation period under the control of the operation controller 22. For example, a general-purpose integrated circuit for speech synthesis can be applied as the speech synthesis unit 24. In this case, the message data itself is given from the operation control unit 22 to perform speech synthesis. In addition, for example, a dedicated integrated circuit for speech synthesis can be applied as the speech synthesizer 24. In this case, the message synthesizer 24 also stores the message data itself and is given an output activation from the operation controller 22. Sometimes speech synthesis is performed based on internally held data.
[0045]
In place of the voice synthesis unit 24, message data obtained by analog / digital conversion of an analog voice signal related to a message is stored as it is, and a digital voice signal read from the storage unit is digital / analog converted. A combination configuration with the D / A converter to be applied may be applied.
[0046]
The voice synthesizer 24 does not output the message voice signal only once, but repeatedly outputs the indicated message voice signal until the display operation is instructed.
[0047]
The speaker 25 generates and outputs the voice signal given from the voice synthesizer 24. Here, the speaker 25 includes a volume adjusting unit that adjusts the volume according to an operation by the operator, a voice amplifying unit that amplifies a voice signal from the voice synthesizing unit 24, a filter that removes unnecessary components such as noise, and the like. May be provided as appropriate.
[0048]
As is clear from the above, the voice synthesizer 24 and the speaker 25 perform an auditory display operation.
[0049]
FIG. 4 is a block diagram showing an example of a detailed configuration of the power supply unit 30 in the fire shutter 1 of this embodiment.
[0050]
In the configuration example illustrated in FIG. 4, the power supply unit 30 includes a solar cell 31, a charging circuit 32, and a secondary battery 33.
[0051]
The solar cell 31 converts ambient light (for example, sunlight) into an electric quantity, and the converted power is given to the charging circuit 32.
[0052]
The charging circuit 32 is also supplied with primary power (power by wiring in the building where the fire shutter 1 is provided) in addition to the converted power from the solar battery 31.
[0053]
The charging circuit 32 is composed of two charging units internally because the voltage at the converted power by the solar cell 31 and the voltage at the primary power supply are different. The charging circuit 32 charges the secondary battery 33 based on the converted power from the solar battery 31 and charges the secondary battery 33 based on the primary power source.
[0054]
Electric power from the secondary battery 33 is supplied as operating power (operating voltage) in the display unit 20. As the secondary battery 33, for example, a battery in which a plurality of rechargeable dry battery shapes are connected in series can be applied.
[0055]
FIG. 5 is a flowchart showing an overview of the entire operation from the occurrence of a fire in the fire shutter 1 of this embodiment, focusing on the display operation.
[0056]
In FIG. 5, the fire shutter 1 monitors that a disaster prevention signal is given from an external device (step S1). When a fire occurs and the fire shutter 1 needs to be closed, an external device gives a fire prevention signal to the fire shutter 1.
[0057]
At this time, the automatic closing device 8 starts the closing operation of the slat 3 with respect to the switch 6 in response to the arrival of the disaster prevention signal, and the driving force of the switch 6 is applied to the winding shaft 5 via the power transmission mechanism 7. As a result, the slat 3 starts to descend (step S2). The activation of the closing operation of the slat 3 is detected by the slat operation state detection unit 9 and notified to the display device 10 (step S3).
[0058]
In the display device 10 notified of the activation of the closing operation of the slat 3, the display unit 20 receives the power supply from the power supply unit 30 and executes the display operation (step S4). In other words, the operation control unit 22 causes the lamp 23 to perform any one of rotation lighting, blinking, fixed lighting, and the like, to perform a visual display operation, and from the voice synthesis unit 24, the voice related to a predetermined message. A signal is given to the speaker 25, and a message voice signal is generated and output from the speaker 25.
[0059]
The message indicated by the message voice signal may directly indicate the closing operation or may indicate information related to the closing operation. An example of a message that directly represents the closing operation can be “Shutter is operating. Please note.” An example of a message with information related to the closing operation is “Fire. Evacuation. Please give me. "
[0060]
Such a display operation is executed until the slat motion state detection unit 9 detects the total closure (or just before the full closure) by the slat 3 (steps S5 and S6). That is, when the display device 10 is notified from the slat operation state detection unit 9 of the full closure by the slat 3 (or just before the full closure), the display device 10 performs a visual display operation by the lamp 23 or an audible display from the speaker 25. End the operation.
[0061]
As described above, in the fire shutter 1 of this embodiment, the display operation is performed during the entire period (or almost the entire period) during which the closing operation is performed.
[0062]
In addition, the above operation | movement is operation | movement when the setting state in the operation | movement permission / prohibition command part 26 of the display apparatus 10 is a display operation permission state.
[0063]
For example, in the maintenance inspection of the fire shutter 1, if the display operation interferes with the work of the worker or the study of the student, the maintenance person sets the operation permission / prohibition command unit 26 of the display device 10. In some cases, only the descent of the slat 3 is confirmed by setting the state to the display operation prohibition state. In this case, the display device 10 does not execute the display operation even if the activation signal for the closing operation is given.
[0064]
According to the fire shutter 1 of the embodiment described above, the following effects can be achieved.
[0065]
Since the display operation of information related to the closing operation is performed together with the activation of the closing of the slat 3, a person in the vicinity of the fire shutter can obtain necessary information. For example, the evacuation route can be obtained depending on the message related to the display.
[0066]
In addition, it is possible to prevent or alleviate the surprise and confusion caused by the sudden operation of the fire shutter 1.
[0067]
Furthermore, since the display device 10 is configured as an independent unit, and the other components can be applied almost as they are, it is easy to add the display device 10 to a fire shutter that is already installed. It can be carried out.
[0068]
Furthermore, since the display operation is both visual and audible, information can be provided more reliably. For example, even if the effective listening range from the speaker is narrow, the display range by the lamp can be exceeded, and it can be more reliably notified that the shutter is closing.
[0069]
Further, since the power supply unit 30 in the display device 10 includes the secondary battery 33 and supplies power to the display unit 20, even if the supply of the primary power supply is stopped due to a fire or the like, the display operation is performed. It can be done continuously. Here, if charging the secondary battery 33 is prioritized by the power from the solar battery 31 over the primary power supply, it is possible to reduce costs such as maintenance of the fire shutter 1.
[0070]
In addition, since the signal line (wiring) 11 connecting the slat operation state detection unit 9 and the display device 10 is protected by the metal molding, the internal wiring can be protected against a flame in the event of a fire, and against an external impact. High tolerance, little change over time, and good appearance due to metallic luster.
[0071]
(B) Modified embodiment
In the description of the fire shutter 1 of the above-described embodiment, the room for various modifications has been described, but other embodiments as exemplified below also belong to the technical scope of the present invention.
[0072]
(B-1) In the description of the above-described embodiment, the display operation is terminated when the slat 3 is fully closed (or immediately before the full closure). However, an automatic display operation end condition is not provided. Anyway. In other words, the display operation started by starting the closing operation may be continued until the display device 10 is destroyed by a fire or an end is instructed by a person. FIG. 6 is a flowchart showing an overview of the entire operation from the occurrence of fire in the fire shutter 1 in this case, centering on the display operation, and corresponds to FIG. 5 described above. In this case, the flow of the operation is stopped by starting the display operation. When the end is instructed by a person, the display operation is ended by the interrupt process. Further, since the detection of the total closure is not performed, the configuration for detecting the total closure can be omitted from the slat operation state detection unit 9.
[0073]
The fact that the display operation is not performed after the entire closure means that the power consumption in the power supply unit 30 can be suppressed, and the advantage that the display is not disturbed when there is a display for evacuation guidance for the entire building. There is. On the other hand, continuing the display operation even after the entire closure has an advantage that an information providing function not directly related to the closing operation can be enhanced, such as an evacuation guidance message can be continuously provided.
[0074]
In the above description of the embodiment, the display operation is terminated when the slat 3 is fully closed (or immediately before the full closure). However, the display operation is terminated after a predetermined time from the start of the closing operation. You may make it let it. In this case, the operation control unit 22 in the display device 20 needs to have a timer 22a by hardware or software as shown in FIG. FIG. 8 is a flowchart showing an overview of the entire operation from the occurrence of fire in the fire shutter 1 in this case, centering on the display operation, and corresponds to FIG. 5 described above. As shown in FIG. 8, in this case, instead of monitoring the total closure, the operation control unit 22 needs to start the timer 22a and monitor a predetermined time (steps S7 and S8).
[0075]
Here, shortening the predetermined time has an advantage that power consumption in the power supply unit 30 can be suppressed as much as possible. In addition, the display operation may be noisy and time reduction may be necessary. Furthermore, for example, in the case of the message “Closed operation. Please evacuate.” If the unclosed area at the opening becomes smaller, it will not be appropriate. Can be prevented by setting the display operation time to a predetermined time.
[0076]
In addition, the installer may arbitrarily set the time measured by the timer 22a. What is necessary is just to set time-measurement time arbitrarily according to the condition of the installation place of the fire prevention shutter 1. FIG.
[0077]
In addition, the display device 10 may be configured to be able to select one of stopping the display operation when it is fully closed and stopping the display operation when the timer 22a has counted a predetermined time.
[0078]
(B-3) In the above description of the embodiment, one type of display mode of the display operation is shown. However, even if there are two or more types of display modes so as to be switched according to the position of the slat 3 or the like. good.
[0079]
FIG. 9 shows an example of the detailed configuration of the display unit 20 of the display device 10 corresponding to two types of display modes. The same and corresponding parts as those in FIG. ing.
[0080]
The display unit 20 shown in FIG. 9 includes two types (two channels) of 24-1 and 24-2 related to different messages as speech synthesis units (note that one speech synthesis unit is physically provided). However, if it is compatible with multiple channels, it is equivalent to providing two types of speech synthesis units). The operation control unit 22 causes the voice synthesis unit 24-1 or 24-2 of one channel to function alternatively in the display operation period. Further, the lamp 23 is adapted to two types of display modes, and the operation control unit 22 alternatively instructs the display mode of the lamps 23 during the display operation period. As the two types of display modes of the lamp 23, if the lamp 23 displays blinking, the blinking cycle is long (the blinking speed is slow) and the blinking cycle is short (the blinking speed is fast). In addition, if the lamp 23 is turned on, the rotation speed is low and the rotation speed is high. Note that two types of lamps 23 with different lighting colors may be prepared as lamps 23, and only one of them may be lit or blinked to respond to two types of display modes.
[0081]
FIG. 10 is a flowchart showing an overview of the overall operation from the occurrence of fire in the fire shutter 1 when the display device 10 is adapted to two types of display modes, centering on the display operation, and corresponds to FIG. 5 described above. is there. In the case of the example of FIG. 10, the display mode is changed before and after the full closure.
[0082]
In FIG. 10, the fire shutter 1 monitors that a disaster prevention signal is given from an external device (step S11). When an operation signal is given from the external device to the fire shutter 1, the automatic closing device 8 is The closing operation of the slat 3 is activated with respect to the opening / closing machine 6, and the driving force of the opening / closing machine 6 is transmitted to the take-up shaft 5 through the power transmission mechanism 7 so that the slat 3 starts to descend (step S12). The activation of the closing operation of the slat 3 is detected by the slat operation state detection unit 9 and notified to the display device 10 (step S13).
[0083]
In the display device 10 notified of the activation of the closing operation of the slat 3, the display unit 20 receives the power supply from the power supply unit 30 and executes the display operation in the first display mode (step S14). In other words, since the closing operation is being performed, the operation control unit 22 performs a display operation in a display mode (flashing speed or rotation speed is fast; a red lamp is lit) that has a higher alerting power to the lamp 23. In addition, the voice synthesizer 24-1 relating to the message during the closing operation causes the voice signal related to the predetermined message to be given to the speaker 25, and the message voice signal is generated and output from the speaker 25.
[0084]
An example of a message in this case is “Shutter is operating. Please be careful.”
[0085]
Such a display operation in the first display mode is executed until the slat operation state detection unit 9 detects the total closure (or just before the full closure) by the slat 3 (step S15). When the display device 10 is notified from the slat operation state detection unit 9 of the total closure by the slat 3 (or just before the full closure), the display device 10 receives the power supply from the power supply unit 30 and performs the display operation in the second display mode. Execute (step S16). That is, since it is after closing, the operation control unit 22 causes the display operation in the display mode (flashing speed or rotation speed is slow; the green lamp is lit) with a lower alerting power to the lamp 23. In addition, the voice synthesizer 24-2 related to the post-closing message is given a voice signal related to a predetermined message to the speaker 25, and the message voice signal is generated and output from the speaker 25. An example of the message in this case is “Please evacuate from the emergency exit on the right side”.
[0086]
Of course, a time limit may be set for the display operation in the second display mode.
[0087]
FIG. 11 is a block diagram showing a specific configuration example of the slat movement state detection unit 9 when the display mode is changed between the closing operation and after the full closing as described above.
[0088]
The slat motion state detection unit 9 in this example includes an upper limit switch 9a and two lower limit switches 9b1 and 9b2.
[0089]
Here, the upper limit switch 9a and one lower limit switch 9b1 indicate the first display mode (period). In other words, the upper limit switch 9a is activated by the descent start of the slat 3, whereby the current path through the upper limit switch 9a and the lower limit switch 9b1 is conducted, and the input detection unit 21 in the display device 10 is the first The necessity of display in the display mode is detected, and then the lower limit switch 9b1 is operated by fully closing the slat 3, whereby the current path that has been conducted is interrupted, and the input detection unit 21 in the display device 10 is The necessity for the end of the display operation in the first display mode is detected. That is, the current path through the upper limit switch 9a and the lower limit switch 9b1 is conducted during the period from the operation of the upper limit switch 9a to the operation of the lower limit switch 9b1, and the first display mode is used during this conduction period. The display operation is executed.
[0090]
The other lower limit switch 9b2 is operated when the slat 3 is fully closed. By this operation, the current path through the lower limit switch 9b2 is conducted, and the input detection unit 21 in the display device 10 is connected to the second limit switch 9b2. The necessity of display operation in the display mode is detected. That is, after the lower limit switch 9b2 is operated, the display operation in the second display mode is executed.
[0091]
As described above, when a plurality of display modes are provided, appropriate information can be provided according to the position of the slat 3 or the like.
[0092]
(B-4) In the description of the above-described embodiment, the fire shutter is continuously executed until the closing operation of the slat 3 is fully closed. However, the present invention is also applied to the fire shutter with the closing operation temporarily stopped. Can be applied.
[0093]
In the case where the fire-stop shutter of the closing operation temporary stop type is activated by the occurrence of a fire, first, the seat plate 3a shown in FIG. 12 (b) is in an intermediate position of the opening from the open state shown in FIG. 12 (a). The slat 3 is lowered until it is located at the position, and the descent of the slat 3 is temporarily stopped at that position. Thereafter, when the re-descent condition is satisfied, the slat 3 is lowered again from the intermediate position shown in FIG. The fully closed state shown in FIG. In other words, in the event of a fire, the slat 3 is lowered halfway to prevent the spread of smoke while fulfilling the function of an evacuation route. When the stop time reaches a predetermined time, a re-descent signal from the central monitoring center, etc. When it arrives, it descends again and shuts down completely, fulfilling its disaster prevention function.
[0094]
In such a closed operation temporary stop type fireproof shutter, for example, the display mode of the display device 10 can be changed before and after the re-descent is activated.
[0095]
As the internal configuration of the display device in this case, a configuration corresponding to the plurality of display modes shown in FIG. 9 described above can be applied.
[0096]
FIG. 13 is a flowchart showing an overview of the entire operation from the occurrence of a fire in the fire shutter 1 when the display device 10 responds to different display modes before and after the start of re-descent, focusing on the display operation. This corresponds to 5.
[0097]
In FIG. 13, the fire shutter 1 (automatic closing device 8) monitors that a disaster prevention signal is given from an external device (step S21), and when an operation signal is given to the fire shutter 1 from the external device, The automatic closing device 8 activates the closing operation of the slat 3 with respect to the opening / closing device 6, and the driving force of the opening / closing device 6 is transmitted to the winding shaft 5 via the power transmission mechanism 7 so that the slat 3 begins to descend ( Step S22). The activation of the closing operation of the slat 3 is detected by the slat operation state detection unit 9 and notified to the display device 10 (step S23).
[0098]
In the display device 10 that is notified of the activation of the closing operation of the slat 3, the display unit 20 receives the power supply from the power supply unit 30 and executes the display operation in the display mode for re-lowering activation (step). S24). For example, the operation control unit 22 causes the display operation in the display mode (the blinking speed and the rotation speed are slow; the yellow lamp is lit) having a lower alerting power to the lamp 23, and restarts again. A voice signal related to a predetermined message is given to the speaker 25 from the voice synthesizer 24-1 related to the previous message, and a message voice signal is generated and output from the speaker 25. An example of a message in this case is “Please evacuate”.
[0099]
Thereafter, when the amount of descent of the slat 3 reaches the amount shown in FIG. 12C, the descent is stopped (step S25). Even in the stopped state of the slat 3, the display operation in the display mode before starting again is continuously executed.
[0100]
In such a stopped state of the slat 3, the automatic closing device 8 monitors the establishment of the re-lowering activation condition (step S26), and when the re-lowering activation condition is satisfied, the automatic closing device 8 Then, the closing operation of the slat 3 is restarted, and the driving force of the opening / closing machine 6 is transmitted to the take-up shaft 5 via the power transmission mechanism 7 so that the slat 3 starts to descend again (step S27). Further, the restart of the closing operation of the slat 3 is detected by the slat operation state detector 9 and notified to the display device 10 (step S28).
[0101]
In the display device 10 notified of the restart of the closing operation of the slat 3 (re-lowering of the slat 3), the display unit 20 receives the power supply from the power supply unit 30 and displays in a display mode after the restart of the lowering operation. The display operation is executed (step S29). For example, the operation control unit 22 causes the display operation in the display mode (the flashing speed or the rotation speed is fast; the red lamp is lit) with the higher alerting power to the lamp 23, and the re-descent activation The voice synthesizer 24-2 related to a later message causes a voice signal related to a predetermined message to be given to the speaker 25, and the message voice signal is generated and output from the speaker 25. An example of a message in this case is “Shutter is operating. Please be careful.”
[0102]
Such a display operation in the display mode after re-lowering activation is executed until the slat operation state detection unit 9 detects the total closure (or just before the full closure) by the slat 3 (steps S30 and S31). That is, when the display device 10 is notified from the slat operation state detection unit 9 of the full closure by the slat 3 (or just before the full closure), the display device 10 performs a visual display operation by the lamp 23 or an audible display from the speaker 25. End the operation.
[0103]
FIG. 14 is a block diagram illustrating a specific configuration example of the slat motion state detection unit 9 when the display mode is changed before and after the re-descent activation as described above.
[0104]
The slat operation state detection unit 9 in this example includes an upper limit switch 9a, two intermediate limit switches 9f1 and 9f2, and a lower limit switch 9b.
[0105]
Here, the upper limit switch 9a and one intermediate limit switch 9f1 indicate the display mode before the re-descent activation. That is, the upper limit switch 9a is activated by the closing activation of the slat 3, and thereby the second current path through the upper limit switch 9a and the intermediate limit switch 9f1 is conducted. This conduction of the current path ends when the intermediate limit switch 9f1 is operated by the slat 3 being lowered again.
[0106]
The other intermediate limit switch 9f2 and the lower limit switch 9b indicate the display mode in the re-descent. That is, the intermediate limit switch 9f2 is operated by the re-descent activation of the slat 3, and thereby the current path through the intermediate limit switch 9f2 and the lower limit switch 9b is conducted. The conduction of the current path is terminated when the lower limit switch 9b is operated due to the slat 3 being fully closed.
[0107]
Although not shown in the figure because it is not directly related to the display operation, a limit switch for detecting the stop position is also provided in order to stop the slat 3 at the intermediate position.
[0108]
As described above, since the display mode of the display operation is changed before and after the re-descent activation in the closed operation temporary stop type fireproof shutter, appropriate information can be provided before and after the re-descent activation.
[0109]
Note that in the closed operation temporary stop type fire-proof shutter, a display operation in a different display mode may be executed after the full closure.
[0110]
In the above, the fire shutter with the closing operation temporarily stopped has been described, but even in the case of a fire shutter that does not stop until it is fully closed, it is displayed during the closing operation according to the area of the opening that is not closed. You may make it change the display mode of operation | movement.
[0111]
(B-5) Of course, the configuration of the power supply unit 30 is not limited to that shown in FIG. 4 described above. That is, the required power may be obtained only from the primary power supply, or only a battery without a simple charging function may be applied. In addition, if the building where the fire shutter 1 is installed has an emergency control power supply that supplies power in the event of an emergency such as a fire in addition to the primary power supply, the emergency control power supply is required for the display operation. A simple power supply may be used.
[0112]
Regardless of the presence or absence of the charging function, placing the battery at the center of the power supply unit 30 has an advantage that the display device 10 can be connected to a fireproof shutter in a place where there is no wiring for the primary power supply.
[0113]
Note that it is preferable to use two types of power supply methods in combination so that the display operation can be performed reliably. For example, when a battery and an emergency control power supply are used together and a display operation is required when there is no supply by the emergency control power supply, the display operation is performed with the power supply from the battery. The display operation may be performed as follows.
[0114]
Moreover, you may make it obtain electric power required for display operation | movement using the energy at the time of the descent | fall of the slat 3. FIG. For example, the descent energy may be converted into electric power by a dynamo, or the energy stored in the mainspring or the like may be converted into electric power using a piezoelectric element or the like, and used for display operation.
[0115]
(B-6) In the above-described embodiment, the display unit 20 and the power supply unit 30 are provided in the same unit. However, the display unit 20 and the power supply unit 30 are configured as separate units, and an electric wire is provided between the display unit 20 and the power supply unit 30. You may make it connect with. It is preferable that the electric wire in this case is also a metal molding.
[0116]
As described above, when the display unit 20 and the power supply unit 30 are configured as separate units, maintenance work for the display unit 20 and the power supply unit 30 can be performed separately.
[0117]
In addition, when there are a plurality of types of display units 20 and power supply units 30, the display device 10 can be configured in any combination. For example, a power supply unit using a solar cell is difficult to apply where the amount of ambient light is small, and a power supply unit using a primary power supply is applied where no primary power supply wiring is provided. However, even when the same display unit is installed in a plurality of locations, the power supply unit may be changed according to the installation location.
[0118]
The unit in which the display unit 20 and the power supply unit 30 are integrated has an advantage that installation work and maintenance work are easy.
[0119]
(B-7) In the description of the above-described embodiment, all the components of the display device 10 are independent from the components such as the automatic closing device 8, but some of the components are replaced with the display device 10. And the automatic closing device 8 or the like. For example, if the automatic closing device 8 has a CPU, the CPU may also have the function of the operation control unit 22 in the display device 10.
[0120]
(B-8) In the above description of the embodiment, the visual and auditory display operations are performed. However, the display operation may be performed for one of the senses. Further, a tactile display operation may be performed. For example, a tactile display operation can be performed by moving the braille plate to the display window.
[0121]
The visual display operation and the auditory display operation are not limited to those in the above-described embodiment. For example, a visual display operation may be performed by displaying a text message on the display. Further, for example, an audible display operation may be performed by sounding a buzzer.
[0122]
Further, the display end time may be changed between the visual display operation and the auditory display operation, or the auditory display operation may be executed first and then the visual display operation may be performed.
[0123]
Furthermore, a display method that appeals to the same sense may be used in combination so that a character message is displayed on the display and the lamp is lit and blinked simultaneously.
[0124]
(B-8) In the above-described embodiment, the present invention is applied to a fire shutter. However, the present invention can be applied not only to a fire shutter but also a door, an overhead door, a blind, a roll screen, and the like. The present invention can also be applied to a building opening / closing device other than the shutter.
[0125]
Of course, depending on the application, the closing activation may be issued manually (for example, a remote control). Further, depending on the application target, not only the display operation based on the closed activation but also the display operation based on the open activation may be executed.
[0126]
【The invention's effect】
  As described above, according to the present inventionTableBy the display operation of the display means, people around the building opening / closing device can know the information that the display means.
