DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic closing device for an office such as a bank provided with a shielding means such as a shutter at an entrance and an exit, and more particularly to an automatic closing device for a customer who is locked when the store is closed can safely exit.

[0002]

2. Description of the Related Art Conventionally, at a predetermined time, the presence or absence of a occupant in a store is searched, and if there is no occupant, a closing operation is performed. The thing which stops a store closing operation if it exists is proposed and implemented.

For example, according to Japanese Patent Publication No. 1-56236, when the detection signal of the search sensor has disappeared between the closing time and the designated time, the shutter is closed, and in particular, the search sensor is always detected. Considering that there is a blind spot, once the shutter is fully closed despite the presence of the occupant, the occupant is expected to move within a limited time after the shutter is fully closed. The shutter is to be opened by the detection of the search sensor by the operation.

In other words, this means that as long as the occupant is expected to move and moves, the search sensor always detects the occupant. However, because the search sensor is faulty or the search sensor is not installed in an appropriate place, the occupants are originally detected by the search sensor between the closing time and the specified time. If the room is trapped without detecting the place to be performed, no matter how much the occupant moves, the occupant cannot be detected, and there is a danger that the occupant is kept in a confined state.

[0005] Accordingly, an object of the present invention is to provide an automatic store closing device in which a closing means is opened by operating the opening means within a predetermined time after the closing of the closing means at the time of closing the store, so that the trapped customer can safely exit. In the offer.

[0006]

[Means and Actions for Solving the Problems] The present invention detects the presence of occupants and the shielding means installed at the entrances and exits of business establishments.
Search means for issuing, a storage means for storing a store closing time, and when the search means does not detect an occupant after the store close time
Closing the shielding means is completed, and the first timing means is activated.
And a release means for opening the shield means when operated only while the first timekeeping means is activated.

Further, the shielding means controller has a second timing means which is activated when the opening / closing means is operated or when the shielding means is fully opened, and counts a predetermined time. At the elapse of time, the closing operation of the shielding means is performed.

[0008]

An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a functional block diagram showing a basic configuration of the present invention. 2 and 3 are flowcharts of closing the store of the apparatus according to the present invention. Reference numeral 1 denotes a shielding unit that is installed at an entrance of a store and separates the store from the outside, for example, includes a shutter and a door. When the shielding means 1 is in the fully open state or the fully closed state, a fully open signal or a fully closed signal is sent to a control means 44 described later by a detector not shown. Reference numeral 2 denotes an occupant sensor that is installed in the store and detects the presence of an occupant in the store. Reference numeral 3 denotes a storage unit that stores a preliminary search time, an opening / closing time, and the like. A shielding means controller for closing or opening the shielding means in accordance with the detection state of the sensor. Reference numeral 5 denotes a remote control (not shown) which outputs an abnormality signal when the shielding means controller 4 detects an abnormality of the shielding means 1. This is a reporting means for reporting to the control center. Reference numeral 6 denotes an opening means for opening the shielding means 1. Note that the opening means 6 is preferably installed in a place near the entrance that can be easily viewed. Further, the storage unit 3 and the notification unit 5 may be built in the shielding unit controller 4.

Next, with reference to FIG. 2, a closing operation when the apparatus according to the present invention is installed in a store will be described. First, the control unit 44 reads the preliminary search time from the storage unit 3 and, when the preliminary search time comes, drives the occupant sensor 2 via the input / output unit 42 to start the occupant preliminary search.

[0010] That is, the preliminary search is to search whether or not customers remain in the store before the store closing operation. When the occupant is detected in the preliminary search, the control unit 44 determines that the customer remains in the store.

Next, the control means 44 reads the store closing time from the storage means 3 in the same manner as described above, and when the occupant sensor 2 detects the occupant in the preliminary search, the timer means 43 comprising a timer or the like. Of the first search timer 431 is started. Then, when the occupant sensor 2 continuously detects the occupant until the time up of the first search timer 431, the second search timer 432 is started.

When the occupant sensor 2 does not detect an occupant continuously for the time T1, for example, while the first search timer 431 is activated, the closing operation of the shielding means 1 is performed via the closing signal output unit 411. Let it start. Then, the activation of the first search timer 431 is canceled with the start of the closing operation,
The second search timer 432 is started.

When the occupant sensor 2 does not detect an occupant before the closing time in the preliminary search, the closing operation of the shielding means 1 is performed via the closing signal output unit 411 as the drive control means 41. At the same time, the second search timer 432 is started. That is, the first search timer 431 does not start when the occupant is not detected in the preliminary search, or cancels before the time-up when the occupant does not detect the occupant, for example, T1 time after the start, and thereafter, The second search timer 432 will be activated. For example, when the second occupant sensor 2 does not detect an occupant while the second search timer 432 is activated, for example, T1 time, the closing operation of the shielding unit 1 is started via the close signal output unit 411.

If the occupant sensor 2 detects an occupant while the shielding means 1 is being closed and a customer enters the store again, the closing means 1 is closed via the stop signal output unit 413. The operation is stopped, and then the shielding unit 1 is opened via the opening signal output unit 412. At this time, the second search timer 43
If the closing means 1 has not been closed before the time of 2 expires, the control means 44 transmits an abnormal signal to a remote control center (not shown) via the notifying means 5.

The occupant sensor 2 searches for the occupant even after the abnormal signal is transmitted, and the occupant sensor 2 searches for the occupant even if the occupant has not reached T1.
When the detection is not continued for a long time, the closing operation of the shielding means 1 is performed to bring the shielding means 1 into a fully closed state.

When the occupant sensor 2 is not installed at an appropriate place or is out of order, the shielding means 1 is fully closed regardless of the presence of the customer. When the shielding means 1 is in the fully closed state, the first timer 433 starts. When the occupant operates the opening means 6 composed of, for example, operation buttons and switches when the first timer 433 is activated, the control means 44 controls the shielding means 1 via the opening signal output unit 412. The second timer 434 is started while being opened to make it fully open.

The second timer 434 is set in advance with a sufficient time including the time when the shielding means 1 shifts from the fully closed state to the fully open state and the time when the customer can go outside. When the second timer 434 elapses a predetermined time, the control unit 44 performs the closing operation of the shielding unit 1 via the closing signal output unit 411 to bring the shielding unit 1 into the fully closed state.

The second timer 434 may be started by a fully open signal from a detector (not shown) when the shielding means 1 is fully opened.

When the shielding means 1 is fully closed, a display means for displaying the operation method and the installation position of the opening means 6 by voice or a display device by a fully closed signal from a detector (not shown) is provided. It may be. Each timer means may be of a variable type that is set as appropriate according to the situation of the store.

[0020]

As described above, according to the present invention, even if the occupant sensor does not function properly due to a malfunction or an improperly installed place within a predetermined time after the shielding means is fully closed, the present invention is applicable to customers. As long as the opening means is operated, the shielding means can be opened, and the customer can be prevented from being trapped.
