Description

  The present invention relates to an electric lock device provided in a building door or the like, and more particularly to an electric lock device having a cylinder lock that can be locked and unlocked by a mechanical key.

An electric lock device having a cylinder lock that can be locked and unlocked by a mechanical key is advantageous in that it can be locked out from a house because it can be unlocked by a mechanical key when the electric lock cannot be operated due to a power failure. .
However, this type of electric lock device has a security problem that the cylinder lock may be illegally unlocked by an illegal key or picking.
Therefore, an electric lock device having a security function of unauthorized unlocking by an unauthorized key or picking has been proposed today.

FIG. 9 is a circuit block showing a conventional example of an electric lock device having a picking crime prevention function.
As shown in the figure, this conventional electric lock device has a so-called one-door-to-lock configuration in which two electric locks 11 and 12 are provided on one door. Detection means 13 and 14 are provided for detecting whether the locked state or the unlocked state is present.

  In the above-described electric lock device, when unlocking is input from the locking / unlocking switch 15, the control circuit 16 drives the drive units 17, 18 to unlock, and when there is a locking input from the locking / unlocking switch 15, the control circuit 16 16 drives the two drive circuits 17 and 18 to perform locking.

On the other hand, when a mechanical key is inserted into the keyhole 19 or 20 and the cylinder 21 or 22 is rotated to lock and unlock the electric locks 11 and 12, the control circuit 16 operates as follows.
That is, the timer of the control circuit 16 starts counting from the time when one of the electric locks 11 is unlocked and the unlock detection output from the detection means 13 is input to the control circuit 16.

  Then, if the other electric lock 12 is unlocked within a predetermined time of the timer and the unlock detection output from the detection means 14 is input to the control circuit 16, it is determined that the electric locks 11 and 12 are normally unlocked. The

Even if the unlock detection output of one electric lock 11 is input to the control circuit 16, the other electric lock 12 is not unlocked within a predetermined time of the timer, and the unlock detection output by the detection means 14 is controlled by the control circuit. When the value is not input to 16, it is determined that the unlocking is performed by picking, and one unlocked electric lock 11 is locked.
In other words, the unlocking by picking is longer than the unlocking by the regular key, so that the other electric lock 12 cannot be unlocked within the predetermined time of the timer. For this reason, the control circuit 16 determines that the unlocking is unauthorized, and the unauthorized unlocking due to picking is prevented by returning the one electric lock 11 from unlocking to locking.

  Even if the unlock detection output of one electric lock 11 is not input to the control circuit 16 within a predetermined time after the other electric lock 12 is unlocked, The electric lock 12 is returned to the locked state.

  On the other hand, in the above-described electric lock device, when the electric locks 11 and 12 are in the unlocked state, if any one of the electric locks is locked with a mechanical key or thumb turn, the control circuit 16 causes the other electric lock to move. It is a follow-up locking system that controls locking.

The unlocking switch 62 and the monitoring circuit 64 constitute second detecting means.

FIG. 3 is a front view showing a configuration example of the above-described locking SW55, intermediate SW56, and unlocking SW57.
As shown in the figure, a fixed contact comprising a locking contact 55a, an intermediate contact 56a, an unlocking contact 57a, and a common contact 66 sequentially disposed on the substrate 65 is provided, and the above-mentioned fixing interlocking with the rotation of the thumb turn 44 is provided. A movable contact 67 joined to the contact is provided. The movable contact 67 comes into contact with the locking contact 55a and the common contact 66, and the locking switch 55 is turned on (conductive). The movable contact 67 is connected to the intermediate contact 56a and the common contact 66. The intermediate switch 56 is turned ON (conductive), the movable contact 67 contacts the unlock contact 57a and the common contact 66, and the unlock switch 57 is turned ON (conductive).

FIG. 4C shows a state where the unlocking switch 57 is turned on by rotating the thumb turn 44 to the unlocking position.
As described above, in this embodiment, the lock SW55, the intermediate SW56, and the unlock SW57 that are sequentially switched by manual operation of the cylinder lock or thumb turn are provided, and the manual operation of the cylinder lock or thumb turn can be detected, and the locked state or unlocked The power consumption in the state is reduced as much as possible.

Subsequently, the detection output of each detection means of the first detection means comprising the locking SW 55 and the monitoring circuit 58, the third detection means comprising the intermediate SW 56 and the monitoring circuit 59, and the second detection means comprising the unlocking SW 57 and the monitoring circuit 60. The operation of the control circuit 52 for inputting the signal will be described with reference to the flowcharts shown in FIGS.
In FIGS. 5 and 6, A and B indicated by ◯ indicate connectors connected to each other, and similarly, C and D indicated by ◯ indicate connectors connected to each other.

As shown in the figure, the control circuit 52 controls the switches in the OFF state of the intermediate SW 56, the locking SW 55, and the unlocking SW 57 to be in a standby state when the cylinder lock is locked or unlocked. To do. (See ST501, ST502, ST601, ST602)
5 and 6 are switched when the cylinder lock is switched from the unlocked state to the locked state, that is, in the order of FIGS. 4C, 4B, and 4A. The operation is shown.

(1) Stop Mode with Intermediate SW Waiting for Activation This embodiment can be applied either after the electric unlocking operation is completed or after the manual unlocking operation is completely performed. For convenience, only after manual unlocking will be described. In this case, the movable contact 67 is in the state shown in FIG. 4C in contact with the unlocking contact 57a. At this time, the control circuit 52 stops supplying power to the locking contact 55a and the unlocking contact 57a (pull-up OFF). And control.
Accordingly, no current flows through the locking SW 55 and the unlocking SW 57, and the movable contact 67 is in contact and turned on, but there is no power consumption.
Note that a voltage is applied between the intermediate contact 56a and the movable contact 67, but since the movable contact 67 is at the position shown in FIG. 4C at this time, the intermediate SW 56 is OFF. There is no power consumption in SW56.

Therefore, when the intermediate SW 56 is in the standby state, the intermediate contact 56a is moved to the movable contact 67a by rotating the mechanical lock to lock the cylinder lock with the mechanical key and joining the movable contact 67 to the intermediate contact 56a. The intermediate switch 56 is turned on by being electrically connected to the common contact 66 through 67. (Refer to ST501 and ST503)
As a result, the intermediate detection output is sent to the control circuit 52 via the monitoring circuit 59.

In response to the input of this detection output, the control circuit 52 stops the power supply voltage of the intermediate SW 56 (pull-up OFF), and also turns on / off voltage (between the movable contact 67, the locking contact 55a, and the unlocking contact 57a). For example, a pulse voltage) is applied. (Refer to ST504 and ST505)
In this state, the operation mode is set, and when the rotation of the cylinder lock proceeds, the movable contact 67 is switched from the intermediate SW 56 to the lock SW 55. The control circuit 52 checks the ON state of the lock SW 55. (Refer to ST506)

If the lock SW 55 is ON, the lock detection output is input to the control circuit 52 via the monitoring circuit 58 because the main lock is locked, and the electric lock 46, which is a sub lock, performs the locking operation by executing the follow-up. (Refer to ST507)
When the electric lock 46 is locked, the lock SW 61 is turned on, and the detection output is sent to the control circuit 52 via the monitoring circuit 63.
In ST506 for checking the lock SW55, if the lock SW55 is not ON, the check is continued for 5 seconds, and if the ON cannot be confirmed within this time, the process returns, and the indicator 37 is unlocked. Inform you. (Refer to ST508)

Subsequently, the pull-ups of the lock SW 55, intermediate SW 56, and unlock SW 57 are turned ON (voltage is applied to each SW), and the ON / OFF state of each SW is checked. (Refer to ST509 and ST510)
At this time, if the intermediate SW 56 is turned off, the control circuit 52 responding to the intermediate detection output sent from the monitoring circuit 59 controls the pull-up of the lock SW 55 and unlock SW 57 to OFF, and enters the stop mode waiting for the start of the intermediate SW 56. Move. (Refer to ST511, ST512, ST501)
As described above, locking from the first standby mode (the above is the first standby mode → the operation mode → the lock operation in the first standby mode is ended and the first standby mode is entered to explain the entry into the first standby mode). The operation ends.

(2) Stop mode with the lock SW waiting for activation When the cylinder lock is operated between locking and unlocking, the intermediate SW 56 is ON as shown in FIG. The control circuit 52 that has received the intermediate output via the monitoring circuit 59 performs the following control according to the stored contents of the memory 68.
That is, if the unlocked state is stored in the memory 68, the lock SW 55 is checked, and when the lock SW 55 is OFF, the pull-up of the intermediate SW 56 and the unlock SW 57 is controlled to be OFF, and the lock SW 55 is Wait for startup and enter stop mode. (Refer to ST513, ST514, ST502)
That is, the second standby mode is set. In this mode, the lock SW 55 is OFF, and the intermediate SW 56 and the unlock SW 57 are both pulled up, so there is no power consumption.

In this second standby mode, when the cylinder lock as the main lock is operated to lock, the switch is switched from FIG. 4 (B) to FIG. 4 (A). The output is sent to the control circuit 52 via the monitoring circuit 58.
At this time, the control circuit 52 turns off the pull-up of the lock SW 55. (Refer to ST515 and ST516)
Thereafter, the above-described operation mode (ST505 to ST508) is performed, and the process proceeds to steps ST509 to ST511.

(3) Stop mode with the unlocking SW waiting for activation When the cylinder SW is operated and the detection output of the intermediate SW 56 and the detection output of the locking SW 55 are simultaneously input to the control circuit 52, the following control is performed.
That is, the control circuit 52 checks the unlocking SW 57, and if the unlocking SW57 is OFF, the control circuit 52 controls the pull-up of the locking SW55 and the intermediate SW56 to OFF and enters the stop mode in which the unlocking SW57 is waiting for activation. (Refer to ST603 and ST604)
That is, in the above case, since the operation is not normal, the first abnormal standby mode is set. In this mode, if the cylinder lock which is the main lock is operated, the control circuit 52 outputs the detection output of the unlock SW 57. In response to the detection output, the pull-up of the unlocking SW 57 is turned off. (Refer to ST605 and ST606)
Thereafter, the above-described operation mode (ST505 to ST508) is performed, and the process proceeds to steps ST509 to ST511.

(4) Stop mode in which the lock SW, intermediate SW, and unlock SW do not wait for activation Detection of each of the lock SW 55, intermediate SW 56, and unlock SW 57 being turned on in the operation of the cylinder lock that is the main lock. When an output is input to the control circuit 52, the pull-up of these SWs is immediately turned OFF, and a stop mode is entered in which the lock SW 55, intermediate SW 56, and unlock SW 57 do not wait for activation. (Refer to ST511, ST513, ST603, ST607)
This operation is a second abnormal standby mode that is an abnormal operation.
This the second time that has become abnormal standby mode, try the electric facilities unlocking operation using the card key.
By this electric locking operation, normal operation can be restored if there is no serious failure.

(5) Change of flowchart The flowchart described above can be changed as follows.
Even if the unlocking state is stored in the memory 68 in step ST513 in which the control circuit 52 determines whether or not the locking SW55 is ON, the unlocking SW57 is checked and the unlocking SW57 is OFF. If so, the stop mode in which the pull-up of the intermediate SW 56 and the locking SW 55 is turned off and the unlocking SW 57 waits for activation, the so-called third standby mode can be set.

In this third standby mode, if the cylinder lock is operated to be unlocked, the unlock SW 57 is turned on, and the control circuit 52 responding to the lock detection output turns off the unlock SW, and then The operation mode (ST505 to ST508) is performed, and the process proceeds to steps ST509 to ST511.
In the second standby mode and the third standby mode, the lock SW 57 or the unlock SW 58 waits for activation according to the storage in the memory 68, but both the lock SW 57 and the unlock SW 58 are activated regardless of the memory 68 storage. You may wait.

Further, when the detection output of the intermediate SW 56 and the detection output of the unlock SW 57 are simultaneously input to the control circuit 52 by the operation of the cylinder lock, the lock SW 55 is checked, and if the lock SW 55 is OFF, the intermediate SW 56 The third abnormality standby mode in which the unlock SW 57 is turned off and the lock SW 55 is waiting for activation can be set.
In the case of the third abnormal standby mode, if the cylinder lock as the main lock is operated to lock, the control circuit 52 responding to the lock detection output with the lock SW 55 turned ON turns off the lock SW 55 pull-up, The above-described operation modes (ST505 to ST508) are performed, and the steps of ST509 to ST511 are controlled.
In the present embodiment, the electric lock 46 does not include the third detecting means, but the electric lock 46 can also include the third detecting means as will be described later. In this case, the main lock and the sub lock are provided. Without any distinction, it is possible to detect the locking of an arbitrary cylinder lock and execute the locking of the remaining cylinder locks.

(6) Crime Prevention Mode for Picking FIG. 7 shows an example of the crime prevention mode when picking is performed when the intermediate SW 56 is in the stop mode and the stop mode is set.
In this case, as shown in FIG. 8, it is desirable that the sub lock also includes all the detection means of the first detection means, the second detection means, and the third detection means.
FIG. 8 is a partial view showing an electric lock 46 portion which is a sub lock, and the others are the same as the block diagram of FIG. 2. And the first detecting means is a lock switch 61 and a monitoring circuit 63. The second detection means is constituted by an unlocking switch 62 and a monitoring circuit 64, and the third detection means is constituted by an intermediate switch 69 and a monitoring circuit 70.
When picking is performed in this stop mode, the intermediate SW 56 is turned on, so the control circuit 52 responding to the intermediate detection output controls the pull-up of the intermediate SW 56 to OFF and starts a 20-second timer.
The timer time is not limited to 20 seconds and can be changed as necessary. (See ST501, ST701, ST503, ST504, ST702)

Subsequently, it is checked whether one picked cylinder lock and the other non-picked cylinder lock are main locks or sub locks.
Then, an ON / OFF voltage (for example, pulse voltage) is applied to the lock SW and unlock SW of the main lock and the sub lock. (Refer to ST703 and ST704)
Then, it is determined whether both the main lock and the sub lock are unlocked or locked. If both the lock and unlock are performed within 20 seconds, it is determined that the operation is normal and the process returns. (Refer to ST705 and ST706)
Furthermore, if one cylinder lock of the main lock and the sub lock is unlocked and the other cylinder lock is not unlocked even after the timer time of 20 seconds elapses, it is unlocked as an unlocking action by picking. Execute lock return to lock one cylinder lock. (Refer to ST707 and ST708)
Or, if one cylinder lock of the main lock and the sub lock is changed from the locked state to the intermediate state, and one and the other cylinder lock are not unlocked even after 20 seconds, which is the timer time, unlocking by picking As an action, a lock return is performed to lock one and the other cylinder locks that are not locked. (Refer to ST707 and ST708)
In addition, when it is in the stop mode with the unlocking SW 57 waiting for activation, the crime prevention mode when picking is performed may be executed.

  Although one embodiment of the present invention has been described above, the present invention is not necessarily implemented as a one-door two-lock configuration including a main lock and a sub-lock, and even in a one-lock configuration including only a main lock. This can be implemented as a configuration for preventing power consumption in the stop mode.

  Suitable for electric lock device with battery power supply.
