JPH0860958A - Open / close counter for building shutters - Google Patents

Abstract

PURPOSE: To facilitate the checking of the number of times that a shutter curtain, which is raised and lowered for opening and closing as it is guided by guide rails on both sides of an opening, was opened and closed by providing the shutter curtain with a counter for detecting the number of times that the shutter curtain was opened and closed according to acceleration as measured when the shutter curtain is stopped. CONSTITUTION: When a shutter curtain is fully closed and a seat plate at its lower end is grounded, an acceleration sensor 8 detects a change in acceleration. Each time the change in acceleration is detected, a counter control portion 10 increments and stores the number of times of detection, and displays it in a display portion 13 when needed. Since the number of times of detection is displayed during operation of a display control switch 11 only for a predetermined period of time set by a timer, the rate of consumption of the battery 15 can be reduced. When the number of times of detection has exceeded a preset number of times, this is displayed without operation of the switch 11, and an alarm means 14 operates. Furthermore, a solar cell 16 is provided as a counter power supply to eliminate the need for battery replacement. Therefore, a counter can be placed afterwards in a portion where it can be easily seen, and whether or not maintenance is required can be determined easily even from the users' side.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing counter for a building shutter installed at an opening such as a doorway of a building.

[0002]

BACKGROUND OF THE INVENTION Generally,
The architectural shutter installed in this kind of building opening is
A switch, a control panel for controlling the drive of the switch, various members such as a chain for transmitting power between the switch and the take-up drum are provided, and in order to perform a safe and smooth opening / closing operation. Are required to maintain and manage these member devices in a normal state. Therefore, it is recommended to perform maintenance at an appropriate time, but there are various types of shutters for construction, from those with high frequency of use to those with low frequency of use depending on the application and construction site, and all such maintenance is required. For example, when the frequency is set to be regular, such as once every six months, the frequency of frequent use may be too long for the next maintenance, and the frequency of low frequency may be longer.

By the way, such maintenance is preferably based on the number of times the shutter curtain is opened and closed.
Maintenance is required when the preset number of times of opening and closing is reached. However, in the past, a counter was installed in the control panel installed inside the shutter case, so in order to check the number of times it was opened and closed, it was necessary to purposely enter the shutter case through the inspection port, forcing general users to do this. It is virtually impossible to do so, and it was the current situation that it is difficult for the maintenance company to check the opening and closing frequency of the shutter curtain, except for looking at the opening and closing times during regular inspections.

DISCLOSURE OF THE INVENTION The present invention was devised with the object of providing an opening / closing counter for a building shutter that can eliminate these drawbacks in view of the above circumstances. In a building shutter configured to open and close a shirt curtain by being guided by guide rails provided on both sides of the opening, a shutter curtain that opens and closes a counter device that counts the number of times the shutter curtain is opened and closed. An acceleration sensor that detects the acceleration that occurs when the vehicle stops, a counter control unit that counts the number of detections of the acceleration sensor and outputs a display command for that number, and a corresponding display based on the input of the display command. It is characterized in that it is configured with a display section that operates. Further, according to the present invention, the number of times the shutter curtain is opened and closed can be easily confirmed by this configuration.

[0005]

Next, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a shutter curtain of a building shutter attached to an opening of a building, and the shutter curtain 1 is wound around a winding drum 2a installed in a shutter case 2 provided above the opening. Then, the shutter curtain 1 that is wound or unwound based on forward / reverse driving of the switch 3 accompanying the switch operation of the opening / closing operation switch (not shown) is guided by the guide rails 4 installed on the left and right sides of the opening to move up and down. As in the prior art, the structure is such that it is moved up and down and the opening and closing is performed by this. Incidentally, 3a is a control unit for controlling the drive of the switch 3, and 3b is the switch 3 and the winding drum 2a.
It is a chain transmission mechanism that interlocks and connects with.

The shutter curtain 1 is formed by a plurality of slats 5 connected in series and a lowermost seat plate (seat plate slat) 6. The seat plate 6 has a lower end edge protruding toward the outdoor side and formed in a substantially L-shape. The indoor side vertical surface of the seat plate 6 is positioned higher than the lower surface of the seat plate 6. The counter body 7 is integrally incorporated. The counter body 7 is provided with an acceleration sensor 8 that detects a shocking acceleration change when the shutter curtain 1 lands on the floor and the opening / closing operation is stopped, and constitutes the counter of the present invention. Here, the counter body 7 is housed in a resin casing 9 having a mounting hole 9a for mounting on the seat plate 6, and the shutter curtain 1 lands on the casing 9 and stops descending. An acceleration sensor 8 that detects a negative acceleration change at the time and a counter control unit 10 that outputs a necessary control signal based on a detection signal from the acceleration sensor 8 are provided. The counter control unit 10 includes:
Further, the operation signals from the display operation switch 11 and the reset switch 12 are connected to be input. Then, the counter control unit 10 outputs a necessary control command to the connected display unit 13 and alarm means 14 based on the signals input from these. By the way, the display unit 1
In order to reduce the consumption of the battery 15, 3 is preferably a liquid crystal display, and as a power source thereof, a solar battery 16 capable of charging the battery 15 is provided in addition to the battery 15. The battery 16 is arranged in the lower portion (bottom portion) of the casing 9 so as to be exposed to the outside when fully opened. Here, of course, if it is provided in a place that is often fully closed during the daytime, it may be provided on the surface or the ceiling surface of the casing 9 without such consideration. Further, in the case where the seat plate has an inverted T-shape and the lower surface (bottom surface) of the casing is closed by the seat plate when fully closed, the through hole 6a is formed in the seat plate 6 as in the embodiment shown in FIG. It is possible to take measures so as to ensure the lighting of the solar cell 16 when it is fully closed.

Next, an example of the control procedure by the counter control unit 10 will be described with reference to the block circuit diagram of FIG. 5 and the flowchart of FIG. First, it is determined whether or not the reset switch 12 has been pushed while the system has been started. In order to avoid a mischievous pushing operation, it is preferable to consider that the pushing operation of the reset switch 12 must be continued for one second, for example. In order to further ensure such consideration for mischief, for example, the setting can be made so that the reset is performed only by the input of the cryptographic switch operation method known only to the maintenance company. When it is determined that such a reset signal is input, the number of times of detection stored in memory, which will be described later, is reset to zero. On the other hand, when it is determined that there is not, it is determined whether or not the detection signal from the acceleration sensor 8 is input. When it is determined that the detection signal has been input, the number of detections is incremented, and this is stored as a new number of detections instead of the one that has been stored so far.

Then, it is judged whether or not the number of times of detection stored in memory exceeds a preset number of times,
When it is determined that the time exceeds, the first display command is automatically output to the display unit 13 and the alarm means 14. The display unit 1 to which this first display command has been input
3 displays the number of times of detection (total number of times) by blinking, for example, prompting an administrator to visually check. On the other hand, as the alarm means 14, one that emits an electronic sound or one that emits light such as a light emitting diode can be adopted, and these can be selected as necessary.

Next, when it is judged that the number of times of detection has not reached the set number of times, it is judged whether or not there has been a switch operation from the display operation switch 11, and only when it is judged that there has been a switch operation, A second display command is output to the display unit 13 during the set timer time. This second display command is preferably different from the first display command, for example, continuous display. The display unit 13 is set so that no display is made when the switch is not operated.

In the embodiment of the present invention constructed as described above, the shutter curtain 1 is driven by the forward and reverse driving of the switch 3.
The opening and closing control is performed, but each time the shutter curtain 1 is fully closed and the seat plate 6 contacts the floor surface and a change in acceleration is detected, the counter control unit 10 advances the number of detections and stores it. However, this will be displayed when necessary.

As described above, in the embodiment of the present invention, the number of times the shutter curtain 1 is opened and closed is determined by detecting the change in acceleration that is always present when the closing operation is stopped, and therefore, the shutter curtain 1 can be arranged anywhere in an easily visible part. It is possible to freely provide the seat plate 6 without having to be the control unit 3a in the shutter case as in the conventional case, and as a result, it is possible for the user to determine whether maintenance is necessary or unnecessary. But you can easily know.

Moreover, since the counter body 7 is of the addition type in which the acceleration sensor 8 detects it and the counter memory circuit counts, the counter body 7 is simply added. Therefore, the counter body 7 is retrofitted to the existing shutter curtain 1. It has the advantage that

Moreover, in this device, the number of times of detection is displayed only for a predetermined timer time when the display operation switch 11 is operated, so that the battery consumption is less than that in the case where it is always displayed continuously. There is an advantage that it can be done. Moreover, in this device, when the number of times of detection exceeds the preset number, the display is automatically made without operating the display operation switch 11, so that the fear of missing the maintenance time can be effectively avoided. And in that case, since the display is different from the display by the switch operation of the display operation switch 11, the administrator is informed that the number of times of opening / closing required for maintenance has been reached. Has the advantage that it becomes more reliable when the alarm means 14 is activated.

Further, in this one, the counter body 7
Has a merit that it can be used for a long period of time without replacing the battery, since the solar battery 16 for charging the battery 15 is provided, although it operates using the battery 15 as a power source. And in this thing, the solar cell 16
It is advantageous in that it is provided in the lower portion of the casing 9 so as to be exposed to the outside and exposed to sunlight to be charged even when the shutter curtain 1 is fully closed.

[0015]

In summary, since the present invention is constructed as described above, the number of times the shutter curtain is opened and closed is counted by detecting the acceleration change that occurs when the closing shutter curtain stops. This means that the counter device does not need to be attached to the control unit inside the shutter case as in the past, and can be installed anywhere on the seat plate, etc. where it is easy to see. Even the user side can easily know. Moreover, since this counter device is an addition type device that simply adds up by counting the number of times of opening and closing detected by the acceleration sensor, it can be retrofitted easily to the existing shutter curtain.
