DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-locking automatic door, and more particularly to a detection sensor provided inside a building.

[0002]

2. Description of the Related Art Generally, an automatic door of an automatic locking type is
To prevent unauthorized intrusion from outside, once the door is closed, it will automatically lock and you will not be able to enter unless you take the unlocking operation such as "Password input", "Key", "Unlock switch inside the building" etc. Security measures have been taken. On the other hand, a detection sensor that detects people approaching the door is provided inside the building, and the automatic door opens in conjunction with the sensor, so that residents inside the building can go out without any special operation can do.

FIGS. 1 to 3 show a conventional automatic lock type automatic door. FIG. 1 is an overall schematic diagram showing the door from the side. A door 6 partitions the space between the ceiling 4 and the floor 3, and the right side of the door 6 shows the inside 3b of the building and the left side shows the outside 3a of the building. An operation panel 5 for unlocking is provided on the outside 3a.
Are provided, and one detection sensor 1 is provided in the inside 3b. FIG. 2 is a perspective view of the inside of a building. In general, the door 6 has a structure in which two doors on the left and right sides slide and open. Although not shown in the drawing, the door has a door lock mechanism, and a fully closed door is normally in a locked state. A slight gap 6a is formed between the fully closed doors. The detection sensor 1 is provided between the wall surface on the center line of the left and right two doors 6 and the ceiling 4 on the inside 3b of the building so as to easily detect a resident who is going out. Has a detection range 1a represented by a dotted line. When the occupant 2 who wants to go out in FIG. 1 approaches the automatic door 6, the occupant enters the detection range 1a indicated by a dotted line, the sensor 1 operates, the lock is automatically released, and the door is opened.

[0004] Next, the operation of a procedure for entering a building from the outside in a conventional automatic lock type automatic door will be described with reference to FIG. First, there is an entrance applicant outside the door (S101). If it is a resident (S102), the operation panel 5 provided on the outside 3a
Is entered or a key operation is performed (S103). This operation releases the door lock and opens the door (S104). The resident can then enter (105). If it is a visitor (S106), the resident in the building is notified of the visit by an intercom provided on the operation panel 5 (S107). The notified resident presses the lock release switch of his / her room (S108).
This operation releases the door lock and opens the door (S104). Then, the visitor can enter (S105). On the other hand, an outsider who is neither a resident nor a visitor does not know the personal identification number, has no key, and has no acquaintance, so he cannot enter the building and returns home (S113). With such a configuration, the conventional auto-locking type automatic door prevents an outsider other than a resident or a visitor from entering the building and enhances security.

[0005]

However, the conventional automatic lock type automatic door is unlocked once the internal sensor detects a moving person or object in the building, even if the door is strictly locked. And has a structure to open the door. Anyone who knows this structure can insert papers such as newspapers and advertisements or thin objects such as steel gauges from the slight gap of the door that occurs when the automatic door is fully closed, and activate the internal detection sensor from the outside It is possible to open the door and intrude illegally without a lock release operation such as "input of a personal identification number".

The intrusion operation will be described with reference to FIG. The intruder (S109) inserts a thin and long insert 7 such as newspaper or magazine into the gap 6a of the door (S110). Then
As shown in the plan view of FIG. 3, the insert 7 is moved within the detection range 1a of the sensor, and the sensor is activated (S111). The door lock is released by the sensor operation and the door is opened (S104). Then, the intruder can enter illegally (S105).

As described above, the detection sensor provided in the conventional auto-locking type automatic door opens the door by activating the sensor from the outside with an insert, thereby permitting unauthorized entry. is there.

[0008] If the unlocking operation is required even when going out by eliminating the internal sensor as a solution, it is possible to prevent the above-mentioned illegal intrusion, but the operation burden on the occupant is increased, and the occupant comfort is increased. It is not desirable to eliminate the internal sensor to make it worse.

Therefore, an object of the present invention is to enable the sensor to discriminate between a fraudulent act of activating the sensor from the outside with an insert and a general resident going out, and not to open the door when the sensor is operated from the outside. An object of the present invention is to provide an automatic lock type automatic door.

It is dangerous for crime prevention to leave a wrongdoer when such wrongdoing is detected, and a means for reporting the fact of wrongdoing to a security company or a manager is desired for crime prevention. .

[0011] Further, from the viewpoint of preventing recidivism and arrest of a wrongdoer, means for identifying such wrongdoer is also desired.

[0012]

In order to solve the above-mentioned problems, the invention according to claim 1 detects a door which is automatically locked when the door is closed and a person approaching the door to leave the building from inside. A detection sensor, an unlocking operation device that allows a visitor from outside the building to perform a predetermined unlocking procedure such as inputting a personal identification number, and automatically unlocks the door by detecting a person and performing a predetermined unlocking operation using the detection sensor. An automatic locking type automatic door including a door opening device for opening the door,
A first sensor for detecting a relatively narrow range on the door side centered on a gap between the closed and opened portions in front of the door, and a second sensor for detecting a relatively wide range on the building side than the detection range of the first sensor And a door opening operation is automatically performed only when the sensors operate in the order of the second sensor and the first sensor.

[0013] The invention according to claim 2 is the first sensor,
When the sensors are activated in the order of the second sensor, the occurrence of an abnormality is reported to a predetermined contact.

Further, the invention according to claim 3 has a security camera for photographing a visitor in front of an automatic door, and when the sensors detect in order of the first sensor and the second sensor, the security camera automatically operates. It has a device for photographing the front of the door.

[0015]

The above-mentioned automatic lock type automatic door has a first sensor for detecting a relatively narrow range on the door side centering on a gap between the closed and open portions in front of the door, and a detection area closer to the building than the detection range of the first sensor. A second sensor for detecting a relatively wide range. Thus, the sensor will have two sensing orders from two directions. Specifically, in the case of fraud that attempts to activate the sensor using an insert from the outside, first the first sensor on the door side detects the insert, and then the second sensor on the building side Detects the insert. As a result, detection is performed in the order of the first sensor on the door side and the second sensor on the building side. This is assumed to be incorrect. When a general resident goes out, the resident walks from the building side to the door, so on the contrary, the second sensor on the building side and the first sensor on the door side are detected in this order. Become.
This is in the normal order. The difference in the detection order between the two sensors makes it possible to detect a fraudulent act of trying to activate the sensor from the outside, which was conventionally impossible, and to distinguish it from an outing act of a general resident. Was.

Further, the door opening operation is automatically performed only when the general resident goes out such that the sensors are detected and actuated in the order of the second sensor and the first sensor (normal order). As a result, it has become possible to prevent the resident from going out due to an illegal act of operating the sensor with the insert from outside while securing the resident's free going out.

Further, by incorporating a notification device,
When the above-mentioned misconduct has occurred, it has become possible to automatically notify the security company promptly.

Further, by installing a camera, it is possible to identify a person who has committed the above-mentioned misconduct.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 FIGS. 5 and 6 show an automatic door-locking automatic door of a building entrance according to an embodiment of the present invention. 5 and FIG.
No. to 7 have already been described in the conventional example and will not be described. The feature of this embodiment is that two sensors, a first sensor 8 and a second sensor 9, are provided. The first sensor 8 is mainly for the purpose of detecting the insert 7 from the gap 6a on the front of the door. Since the insert is inserted from the gap 6a, the vicinity of the door gap 6a is indicated by a broken line in the plan view of FIG. Has a relatively narrow detection area 8a that is elliptical with respect to the floor surface. The first sensor 8 also has a purpose of detecting the occupant after the second sensor 9 when the resident goes out, so that the occupant does not need to approach the door 6 so much to open the door. It is desirable that the range 8a has a certain thickness in the direction of the building. The second sensor 9 is mainly intended to detect a resident who is going out, and to detect a resident walking toward the center of the door from various directions in the building without fail,
It has an elliptical relatively wide detection range 9a with respect to the floor centered on the center of the door. In the figure, the detection range 9a of the second sensor is provided on the building side so as not to overlap with the detection range 8a of the first sensor. However, if the detection order of the two sensors is not affected, the detection range is not changed. Some overlap may be possible. In this embodiment, the upper door of the automatic door is provided with a plurality of sensors that are illuminated in the vertical direction. However, if the same operation is performed, the plurality of sensors that are illuminated in the lateral wall of the automatic door are provided. Is also good.

Further, the present embodiment is characterized in that when the second sensor 9 and the first sensor 8 are operated in the order (normal order), the door is opened, and the first sensor 8 and the second sensor 9 are opened. In the order (misorder) of (1).

The intrusion operation in this embodiment will be described with reference to FIG. The entry operation of the resident (S102) and the visitor (S106) is exactly the same as in the prior art, and will not be described. Intruder (S
109) inserts a thin insert 7 such as newspaper or magazine into the gap 6a of the door (S110). First, the tip of the insert 7 enters the detection range 8a of the first sensor shown in FIG. Sensors are activated. When the insert 7 is further inserted into the back, the tip enters the detection range 9a of the second sensor, and the second sensor operates (S111). When the sensors operate in the order of the first sensor and the second sensor (wrong order), the lock is not released and the door is not opened because the detection order is different from the preset detection order (S112). The intruder gives up on entering and returns (S113).

Of course, when the resident goes out, when approaching the automatic door, the body passes in the order of the detection ranges 9a and 8a, and the order of the second sensor 9 and the first sensor 8 (normal order). Since the sensor is activated, the lock is released and the door is automatically opened and the user can go out freely as before.

Therefore, according to the present embodiment, it is possible to detect a fraudulent act of trying to activate the sensor from the outside, and further, it is possible to prevent the resident from going out and prevent intrusion due to the fraudulent act. It became.

Second Embodiment In the first embodiment, when the first sensor 8 and the second sensor 9 are operated in the order (misorder), the door does not simply open, but in the second embodiment, the door is not opened. If the sensors are activated in this order, it is determined that the act is a fraudulent act of activating the sensor from the outside, and a report is further made to a security company or the like. This allows
The fact that the fraud has occurred is reported to a security company or the like, and the crime prevention property is further enhanced.

Third Embodiment In the third embodiment, when the sensors are activated in the order of the first sensor 8 and the second sensor 9 (in the wrong order), the sensor is mounted on the upper part of the automatic door on the building side or in the building. The security camera takes a picture of the area near the entrance of the automatic door where the unauthorized entry work was performed. As a result, it is possible to identify the person who attempted to gain unauthorized access.

[0026]

According to the present invention, since a plurality of sensors having different detection ranges are provided, it is possible to discriminate between a fraudulent act of activating the sensor with an insert from outside and a general resident's outing act due to a difference in the order of detection of the sensors. It is now possible to open the door only when going out. Therefore,
An automatic lock type automatic door is provided which can prevent illegal intrusion while securing the resident's free going out, and has high security. In addition, when such misconduct has occurred, the security is further enhanced by notifying the security company or the like and photographing the scene with a security camera.
