Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an abnormality notification device for an electric shutter installed in an opening of a house or a building.

[Problems to be Solved by the Prior Art and the Invention] Generally, in this type of electric shutter, an obstacle detection switch is provided at the lower end of the shutter curtain, and when the obstacle detection switch detects an obstacle when the shutter curtain is lowered. There is a type in which the detection signal is transmitted from a transmission unit, received by a reception unit provided on the skeleton side, and based on this, the descent of the shutter curtain is urgently stopped.

By the way, in this device, when an abnormality such as an obstacle detection operation is performed, it is necessary to notify a nearby person of this, and it has been attempted to provide an abnormality alarm such as a buzzer. At most, the annunciator is attached to a member device provided on the skeleton side, such as a shutter curtain drive control unit or an open / close push button switch.

As a result, even if the abnormality alarm is activated when an obstacle is detected, the notification is issued not from the lower end of the shutter curtain that actually hits the obstacle, but from the side of the skeleton away from the obstacle. By the way, when such anomaly notification is issued, a person usually first pays attention to the place where the anomaly notification is issued, and there is a problem that delay in noticing the existence of an obstacle is caused.

Means for Solving the Problems In view of the above-mentioned circumstances, the present invention has been made with the object of providing an abnormality notification device for an electric shutter capable of eliminating these disadvantages, and it is intended to provide a structure for a building. An obstacle detection switch is also provided at the lower end of the shutter curtain of the electric shutter that opens and closes the opening of the electric shutter, and a detection signal provided by the obstacle detection switch is provided on the skeleton side from a transmitter provided at the lower end of the shutter curtain. In the electric shutter configured to stop the lowering of the shutter curtain by transmitting the abnormality alarm, an abnormality alarm is provided at the lower end of the shutter curtain, and the abnormality alarm is detected by an obstacle detection switch. In this case, it is connected to an obstacle detection switch so as to perform the notification operation.

Further, in the electric shutter, an abnormality alarm is provided in the transmission unit, and the abnormality alarm is connected to the obstacle detection switch so as to be activated by the detection operation of the obstacle detection switch, and at the lowermost end of the shutter curtain. An abutting member that comes into contact with the floor when the shutter curtain is lowered to the fully closed state, and restricts the obstacle detection switch from touching the floor in the fully closed state. But also.

According to the present invention, when the obstacle detection switch is operated to detect an abnormality, the abnormality notification is performed from the vicinity of the switch, thereby attracting the attention of the surrounding people to the part. is there.

Example Next, an example of the present invention will be described with reference to the drawings.
In the drawings, reference numeral 1 denotes a shutter curtain of multiple electric shutters connected to a wide opening, and each shutter curtain 1 is a remote switch 2 provided in a control room or the like.
Alternatively, by the forward / reverse drive of the electric switch 4 accompanying the operation of the push button switch 3 provided in the vicinity of the opening, the storage position wound around the shutter case 5 and the closed position in which the opening is closed by hanging down. It moves up and down to change its shape, and all of these configurations are conventional.

Reference numeral 6 denotes a seat plate disposed at the lowermost end of the shutter curtain 1, and an obstacle detection switch (for example, a tape switch) 7 is provided over substantially the entire bottom surface of the seat plate 6. Further, an abnormality detection control device 8 is provided on the seat plate 6, and the abnormality detection control device 8 detects a voltage drop abnormality of a battery (not shown) built in the abnormality detection control device 8. A detector 9, a control unit 10 to which detection signals from the detector 9 and the obstacle detection switch 7 are input and to output a necessary control signal based on the detection signal; An abnormal signal transmitting unit 11 that receives an abnormal output signal of voltage drop detection and transmits an abnormal signal, an alarm lamp 12 that lights up upon receiving the abnormal output signal, a sound alarm 13 that emits an alarm sound such as a buzzer sound, and the like. Although it is configured using a member device,
In the embodiment, the abnormal output signal from the control unit 10 is, for example, the fifth signal in the case of detecting the obstacle and the case of detecting the voltage drop.
As shown in the figure, transmission is performed by changing the pulse (for example, pulse pitch, pulse shape, etc.), whereby the abnormality type is identified.

On the other hand, on the skeleton side where the shutter case 5 is provided,
An abnormal signal receiving unit 14 that receives an abnormal signal from the abnormal signal transmitting unit 11 and a control unit 15 that receives the received abnormal signal and outputs a control signal based on the input abnormal signal are provided. That is, the control unit 15 determines whether the received abnormal signal is an obstacle detection signal or a voltage drop detection signal, and outputs the determined abnormal signal from each output port. And a control signal output unit 15b that outputs a necessary control command such as an emergency stop to the control unit 16 of the switch 4 by inputting these determined abnormal signals.
The abnormality notification lamps 17 and 17a provided at appropriate positions on the skeleton side of the push button switch 3 and the like are turned on based on the output signal from the determination unit 15a, while the control signal output unit 15b An operation command is output to a sound alarm 18 provided in the remote control room.

In the embodiment of the present invention configured as described above, the obstacle detection switch 7 is activated when the shutter curtain 1 is lowered.
When an obstacle is detected, the detection signal is transmitted from the abnormality transmitting unit 11, and the emergency stop of the shutter curtain 1 is performed based on the detection of the detection signal by the abnormality signal receiving unit 14.

As described above, the emergency operation is performed based on the detection of the obstacle or the detection of the voltage drop. At the same time, the notification sound and the notification light are emitted from the seat plate 6 at the lowermost end of the shutter curtain 1. Therefore, people in the vicinity can be intuitively aware of the existence of obstacles by being alerted to their sources, and can immediately take measures such as removing obstacles to ensure safety. Is significantly improved.

In addition, since this is configured so that an obstacle detection signal and a voltage drop detection signal can be transmitted from one control unit 10, the number of parts can be reduced as compared with the case where separate control units are provided. It is convenient.

Further, the present invention is not limited to the above embodiment,
The effect becomes remarkable when used in a shutter curtain 1 as shown in the following second embodiment.

That is, the shutter curtain 1 of the second embodiment is
Abutting members 19 are provided at the left and right ends of the shutter curtain 1. When the shutter curtain 1 is lowered at the lowest position, the obstacle detecting switch 7 does not abut against the floor surface in a state where the abutting members 19 abut against the floor surface. It is configured as follows. Therefore, the obstacle detection switch 7 is
Unlike when there is no abutment member 19 when fully closed, it does not come into contact with the floor to be in the same state as the obstacle detection state. Therefore, the obstacle detection switch 7 is set to a state in which the detection operation can be performed even when fully closed. Can be kept. With this arrangement, when the shutter curtain 1 is forcibly opened from the outside when the hand or tool is pushed under the obstacle detection switch 7 when the shutter curtain 1 is fully closed, the shutter curtain 1 is pushed by the obstacle detection switch. 7, an alarm sound is emitted from a sound alarm 13 provided in the abnormality detection control section 8 below the shutter curtain 1.

This notification sound 13 is provided outside, as in the case of a conventional push button switch 3 or the like provided on the indoor side, where the alarm transmission source is distant and the window of the shutter is closed inside the shutter curtain 1. Unlike the one in which the notification sound leaks only slightly, it is emitted so that it can be heard almost directly from the lower side of the shutter curtain 1 into which the hands are pushed,
By giving psychological pressure to the intruder, not allowing him to give up on trespassing, but notifying a third party outdoors that there is a trespasser, Security can be improved. Further, since the obstacle detection switch is always kept in an operable state, the obstacle detection switch can detect an obstacle even when the shutter curtain 1 is raised, which is advantageous for preventing mischief of children.

It should be noted that, in the present invention, the abnormality notification is performed differently for the obstacle detection and the voltage drop detection, so that the determination is simple and the abnormality that has occurred can be dealt with immediately. Is good.

[Effects] In summary, since the present invention is configured as described above, when an abnormality such as obstacle detection is detected, a notification operation is performed from the lowermost portion of the shutter curtain. Therefore, people in the vicinity can be intuitively aware of the existence of obstacles by drawing attention to the source, and can immediately take necessary measures such as removing obstacles immediately. Safety is significantly improved.

In addition, at this lower end of the shutter curtain, an abutting member is provided which comes into contact with the floor when the shutter curtain is lowered to the fully closed state, and the obstacle detection switch is mounted on the floor in the fully closed state. When the grounding is restricted, the obstacle detection switch can be maintained in the detection operable state even when the switch is fully closed. Accordingly, when the switch is fully closed, the shutter curtain is opened in an attempt to open the shutter curtain. When the hand is pushed into the lower end of the tartar curtain, the obstacle detection switch detects this, and the notification operation is performed at the lower end of the shutter curtain, so that the alarm is installed on the indoor side such as a push button switch. The source of sound is far away, and only a small amount of notification sound leaks to the outside, as in the case where a sash window is closed inside the shutter curtain. In contrast, it can act almost directly beneath the shutter curtain with its hands pushed in, giving psychological pressure to the intruder and giving up on trespassing. Not forgive
A third party outside can be notified that there is an illegal intruder, and the security can be improved.
