Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention detects the locking and unlocking positions of a manual switching lever of a lock provided on a door or the like, and unlocks from an outdoor side by, for example, picking. The present invention relates to a lock monitoring device that issues an alarm when such an abnormality occurs.

[0002]

2. Description of the Related Art Recently, there has been a large number of attempts to pick up empty doors called "picking" in which a door lock is pryed open by a specially processed metal tool (picking tool). In addition, damage is caused not only to metal items but also to room users. It is not uncommon for thieves to recover and develop violent crimes. Conventionally, picking is a technique by which a key expert opens a lock without a key in an emergency, and the number of thieves specializing in picking that abuse the key is increasing rapidly. In order to cope with such a problem, for example, as disclosed in Japanese Patent Application Laid-Open No. 06-317050 and Japanese Patent Application Laid-Open No. 09-158557,
The internal structure of the lock itself is complicated so that it cannot be easily unlocked by a picking tool, or the keyhole is bent to prevent unauthorized unlocking by picking.

[0003]

However, the conventional method for preventing unauthorized unlocking by picking has a problem that the structure of the lock is complicated and expensive. In addition, replacing all existing door locks with ones whose structure has been changed requires a lot of cost and time, and with the advanced picking technology, it is impossible to pick even complex locks whose structure has been changed. There was a problem that the anxiety that it was not always remained. The present invention has been made in view of such circumstances, and detects an unlocking from an outside of a door by an abnormal method without modifying an existing lock and generates an alarm to prevent crime such as picking. It is an object of the present invention to provide an effective lock monitoring device.

[0004]

According to the present invention, there is provided a lock monitoring device according to the present invention, wherein a control device main body is mounted on an indoor side of a door, and a manual switching lever for rotating a lock provided on the door is used. A lock monitoring device that detects a locking and unlocking position and issues an alarm when the unlocking operation from the outdoor side is abnormal, and the control device main body includes a locking and unlocking position of a manual switching lever. A lever position detecting means for detecting a contact or non-contact and outputting a locking or unlocking signal, and issuing a warning signal when a locked lock is unlocked and the manual switching lever is kept in the same state for a predetermined time. It has an unlocking operation abnormality detection unit and an alarm generation unit that emits an alarm sound based on the output of the unlocking operation abnormality detection unit.

Accordingly, when the lock is changed from the locked state to the unlocked state from outside the door by the picking tool, the manual switching lever rotates from the locked position to the unlocked position. In this state, the door can be opened, but the lever position detecting means detects the unlock position of the manual switching lever and outputs an unlock signal. When the manual switching lever is kept in the unlocked state for a predetermined time, for example, about 1 to 3 seconds, the unlocking operation abnormality detecting unit is operated by the unlocking signal, and the alarm generating unit is output by the unlocking operation abnormality detecting unit. A loud alarm sound can be heard from the surroundings to intimidate the intruder and inform the surroundings that the door has been unlocked abnormally. By the way, when the lock is unlocked by the picking tool without using the normal key, it is almost impossible to return from the unlocked state to the locked state immediately by the picking tool, that is, in about 1 to 3 seconds. . When the lock is unlocked using a normal key, it is possible to easily switch between the locked state and the unlocked state in a short period of time. When the operation is performed with the key,
By not operating the unlocking operation abnormality detection unit, it is possible to prevent the generation of an alarm sound after performing the unlocking operation.

In the lock monitoring device according to the present invention, the control device main body includes indoor operation detecting means for detecting the operation of the manual switching lever from the indoor side, and when the indoor operation detecting means operates, the unlocking operation is performed. The generation of the alarm signal from the abnormality detection unit or the alarm sound from the alarm generation unit may be stopped. In this case, for example, when the user in the room goes out, the manual switching lever is pinched from the inside of the door with a finger to perform the unlocking operation. Detection by the indoor operation detection means consisting of a contact sensor, etc., stops the generation of the alarm signal from the unlocking operation abnormality detection unit or the alarm sound from the alarm generation unit as a normal unlocking operation without picking, and performs manual switching. An unlocking operation when the lever is turned with a finger can be distinguished from an abnormal unlocking operation due to picking.
At this time, when the lever position detecting means detects that the unlocking state has been achieved by the normal unlocking operation, the alarm generating unit generates a guidance sound having a lower volume than the alarm sound, thereby releasing the unlocking state. Can be informed that

In the lock monitoring device according to the present invention, the control device main body may emit a lock confirmation sound when the lever position detecting means confirms the locked state. in this case,
For example, when a room user locks with a key from the outside of the door to go out, or when turning the manual switching lever after entering the room to lock, the lever position detection means checks the locked state and For example, since a lock confirmation sound different from an alarm sound such as a set melody is issued, it can be confirmed that locking has been securely performed. Therefore, even if you lock it unconsciously, you may be unsure if you locked it after you go out or enter the room, but when you lock it, listen to the lock confirmation sound and be conscious that you have locked it clearly You can never forget to lock. For example, if you forget to lock when you go out, and when you are away from the door, the unlocked state will continue and a guidance sound will be heard, so you can sense that it is unlocked, so lock with the key You will notice what you have to do.

In the lock monitoring device according to the present invention,
A relay alarm device that receives an alarm sound from the alarm generation unit or another alarm signal different from the alarm sound and issues an alarm may be provided separately from the control device main body. In this case, a lock signal indicating a locked state in response to a signal from the lever position detecting means is provided to the control device body attached near the manual switching lever inside the door, and the locking / unlocking operation is performed by a key during a predetermined time. When the operation is performed, a normal unlocking signal for preventing the unlocking operation abnormality detecting unit from operating and the lock in the locked state are unlocked, and an alarm is generated when the manual switching lever is kept in the same state for a predetermined time. A signal transmitting unit for transmitting an alarm signal by non-contact communication means such as radio waves or light is provided. In addition, a relay alarm device that can be installed separately from the control device main body is provided in a room or the like separated from the position of the door, and the relay alarm device is provided with a signal receiving unit that receives a signal transmitted from the signal transmitting unit, A relay alarm generating unit that emits an alarm sound in response to the alarm signal received by the signal receiving unit is provided. Therefore, when abnormal unlocking due to picking occurs, even in a room separated from the door, etc., the relay alarm generation unit of the relay alarm device via the alarm signal transmitted from the signal transmission unit of the control device main body provided on the door. The picking operation can be sensed by hearing the alarm sound generated from the device, and a crime prevention measure can be taken immediately.

In the lock monitoring device according to the present invention, the relay alarm device has a human detection sensor for detecting the presence of an intruder or a house person indoors, and furthermore, the manual switching lever is released when unlocking from outside. The lock state is established, the lock state is established within a predetermined time, and then it is confirmed that the unlock state is established, and an output for turning on the electric equipment including the indoor lighting is issued, and the unlocked lock is locked. State, and the human detection sensor detects that it is unattended, outputs an output that turns off electrical equipment including lighting, and has an equipment control unit that detects an intruder and generates an alarm signal. Good. In this case, the device control unit of the relay alarm device receives signals (locking signal, normal unlocking signal, alarm signal) from the lever position detecting means and unlocking operation abnormality detecting unit provided in the control device main body, for example, a TV camera. It operates by receiving a signal from a human detection sensor that analyzes images and detects people, for example, when a room user returns home and performs a normal unlocking operation, or when the surroundings are dark, it is used. Before the person enters the room, the lighting of the room can be turned on by the device control unit so that the user can safely enter the room. In addition, not only lighting but also home electric appliances such as radios and televisions can be turned on before the user enters the room.

And a power supply unit 33 for supplying power to each of the components.

Here, the operation of the lock monitoring device 10 according to one embodiment of the present invention will be described. First, when the lock 13 is unlocked from the outside of the door 11 by, for example, a picking tool while the lock 13 is in the locked state, the manual switching lever 16 rotates from the locked position to the unlocked position. In this state, the door 11 can be opened, and the lever position detecting means 17 detects the unlocking position of the manual switching lever 16 and outputs an unlocking signal S2. The detection unit 18 causes the alarm generation unit 19 to generate a guidance sound according to the guidance signal S3. When the manual switching lever 16 holds the unlocking state for a predetermined time, for example, about 1 to 3 seconds, the unlocking operation abnormality detecting unit 18 determines that the unlocking operation is abnormal and the unlocking operation abnormality detecting unit 18 Alarm signal S
4 is output to generate an alarm sound from the alarm generation unit 19. Thereby, it is possible to intimidate an intruder trying to enter the room indoors by picking and to report that the surroundings have been unlocked abnormally.

Further, when abnormal unlocking due to picking occurs, the non-contact communication signal S7 transmitted from the signal transmission section 25 of the control device main body 12 provided in the door 11 even in a room separated from the door 11 or the like. The picking operation can be sensed by listening to the alarm sound transmitted from the relay alarm generator 29 of the relay alarm device 27 via the relay alarm device 27, and a crime prevention measure can be taken immediately. On the other hand, when the lock 13 is unlocked using the normal key 14, a guide sound is first generated from the alarm generating unit 19 by the guide signal S 3 by the unlock signal S 2, but the lock state and the unlock state are easily changed. Since the state can be switched to a short time, when the locking / unlocking operation is performed by the key 14 for a predetermined time, for example, about 1 to 3 seconds, the unlocking operation abnormality detecting unit 18 determines that the unlocking operation is normal. After the unlock operation is performed, for example, a guide sound is generated for about 10 seconds, and then the guide sound and the alarm sound are generated by generating the normal unlock signal S6 and not generating the alarm signal S4. Both of them are not sounding. At this time,
When the user is in the unlocked state after entering the room, he or she listens to the guide sound, so that it is possible to secure the safety by regularly locking the vehicle by the manual switching lever 16.

Further, for example, when the user of the room goes out to pick up the manual switching lever 16 from the inside of the door 11 and unlocks it, the human body portion 21 such as the finger holding the manual switching lever 16 is moved. , Detected by the indoor operation detecting means 22 composed of a non-contact sensor, transmits an inoperative signal S5 to the unlocking operation abnormality detecting unit 18 as a normal unlocking operation not based on picking, and outputs an alarm sound from the alarm generating unit 19. Do not generate. However, since the manual switching lever 16 is in the unlocked state, the warning sound is generated from the alarm generating unit 19 by the unlock signal S2. Further, for example, when the user of the room locks with the key 14 from the outside of the door 11 to go out, or after entering the room, the manual switching lever 16
When the lever is rotated and locked, the lever position detecting means 17 is used.
Confirms the locked state, and emits a lock confirmation sound different from an alarm sound such as a set melody from the lock sound generation unit 23 according to the lock signal S1 that is in the security start mode. Yes, you will not forget to lock. If the lock with the key 14 is forgotten here, the unlocked state continues and a guidance sound is emitted, so that the user must be aware that the lock must be performed, and it is possible to prevent the lock from being forgotten.

Further, for example, when a user of the room
When the normal unlocking operation (unlocking / locking / unlocking operation) is performed by 4 and the surroundings are dark, the lighting of the room, which is an example of the electric device 30, is turned on before the user enters the room from the device control unit 31. You can turn it on and put it in your room safely. In this case, not only lighting,
The electric device 30 such as a radio or a television can be turned on. Further, for example, when the user in the room goes out, the unlocked lock 13 is locked by the key 14, and upon receiving the lock signal S1 from the lever position detecting means 17, the signal transmission unit 25 transmits the non-contact communication signal S7. Transmits the locking signal S1 from the signal receiving unit 28 which has received the non-contact communication signal S7 according to the locking signal S1 in accordance with the locking signal S1, and transmits the locking signal S1 to the device control unit 31.
Is received, and when the human detection sensor 32 detects that the inside of the room is unoccupied, the device control unit 31 turns off the light and automatically turns off the light so that the user does not forget to turn off the light. it can. When a user such as a family member goes out and locks with the key 14, a security start mode is set. For example, when a person breaks through a window and enters,
The human detection sensor 32 operates and the device control unit 31
As a result, an alarm sound is generated from the relay alarm generation unit 29, and the intruder can be threatened.

As described above, the present invention has been described with respect to one embodiment. However, the present invention is not limited to the configuration described in the above embodiment, and is described in the claims. And other embodiments and modifications that can be considered within the scope of the present invention. For example, in the above embodiment, the lever position detecting means 17 and the indoor operation detecting means 22
Has described an example using a non-contact sensor using a photoelectric element, but a non-contact sensor using a sound wave, an electromagnetic wave, a capacitance, a heat ray, or the like may be used. Further, the lock confirmation sound generated from the lock sound generation unit 23 may be different from the alarm sound such as the melody described in the above embodiment, for example, may be an intermittent sound or a continuous sound whose volume is lower than the alarm sound. Further, in the above-described embodiment, an example has been described in which the lock sound is generated from the lock sound generation unit 23 by the lock signal S1, but a sound different from the guidance sound or the alarm sound from the alarm generation unit 19 is generated by the lock signal S1. , And the locking sound generation unit 23 may be omitted. In the above-described embodiment, the relay alarm device 27 receives the non-contact communication signal S7 by the signal receiving unit 28 and generates an alarm.
May be received by a microphone, for example, to generate an alarm.

In the above embodiment, the relay alarm device 2
Although the example in which 7 was provided in the room was described, the relay alarm device 27 was also provided in the management room of an apartment or office,
Even when the user at the installation location is away, an administrator or the like may be able to detect an abnormal unlocking operation such as picking or the occurrence of an intruder. Furthermore, a small telephone such as a mobile phone is installed in the relay alarm device 27, and the input / output switch of the mobile phone and the user are always carried by the device control unit 31 provided in the relay alarm device 27. A switch operation mechanism for operating a selection switch for talking to the telephone number of the mobile phone may be provided. In this case, when the alarm signal S4 is input to the device control unit 31 when going out, the input / output switch and the selection switch are operated to generate an alarm sound generated from the relay alarm generation unit 29 due to picking or the occurrence of an intruder. A notification is sent to the user who is out, and after a predetermined time (for example, 10 to 30 seconds), the input / output switch is operated to stop the transmission of the mobile phone. Thus, an abnormal operation such as picking can be sensed even when the user is out. In addition, since the control device main body can be compactly assembled, it can be built in a door or a lock of an entrance. In addition, the same operation as in the above-described embodiment can be performed by interlocking the occupancy confirmation lock having a structure capable of confirming the lock by the key and the control device main body.
