However, for example, if the facility is an apartment and a mail box is installed outside the door equipped with an electric lock having an automatic locking function, the resident of the apartment who is related to the facility picks up the mail. Even in order to get out of the door in a short time, it was necessary to bring the key of the door out, and if the key was forgotten, it would be locked out of the door.

Therefore, as a means for solving the above problems, the electric lock control system according to the present invention has an automatic locking function that is installed on the door and automatically locks when the door is closed. An electric lock, a thumb turn device provided on the surface of the door, and a thumb turn knob capable of manually switching the locking / unlocking state of the electric lock are connected to the electric lock, and the thumb turn device is provided. At the same time, a function stop device capable of stopping the automatic locking function while maintaining the locked / unlocked state of the electric lock is provided, and the automatic locking function of the electric lock is performed after the activation of the function stopping device. The electric lock is unlocked by the thumb turn picking operation, and the stopped state is maintained until the electric lock is locked again by the thumb turn picking operation.

In addition, while the locked / unlocked state of the electric lock is maintained, the locked state is maintained when the electric lock is locked, while the unlocked state is maintained when the electric lock is unlocked. It means to maintain. Therefore, the electric lock is not operated from the locked state to the unlocked state only by activating the function stop device, and vice versa. As a result, it is possible to prevent a person who attempts to invade by unreasonably unlocking the electric lock from unlocking the electric lock only by activating the function stop device without operating the thumb turn device. Then, by providing the function stop device according to the present invention, it is possible to prevent a deterioration of the crime prevention function of the automatic locking function of the electric lock.

Further, the automatic locking function in the stopped state may be restored when the electric lock is locked by the operation of the thumb turn picking.

Further, it is preferable that the function stop device restores the automatic locking function after a lapse of a certain period of time after activation.

Further, the function stop device may have only a function of stopping the automatic locking function. That is, the electric lock that is locked by the activation of the function stop device is not unlocked. Therefore, even if a suspicious person operates the activation switch of the function stop device from between the door and the door frame by using some kind of tool, the electric lock cannot be directly unlocked by the operation. It is possible to prevent the invasion of suspicious persons. As a result, the presence of the function stop device does not cause a deterioration in the security function of the electric lock having the automatic locking function.

Furthermore, the thumb-turn device may include a case provided with the thumb-turn knob, and an activation unit for activating the function stop device may be provided on the surface of the case.

Further, the starting unit may be a push button.

Here, it is preferable that the push button has a structure in which the protruding state is automatically returned by an elastic force such as a spring force when the push button is pushed. This eliminates the need for the operation of returning the state of the push button after activating the function stop device, and the operation of unlocking the electric lock can be immediately performed. Further, the push button may be a touch sensor type switch. If it is a touch sensor type switch, the push button does not change the mechanism, so there is no need to return the state of the push button after activating the function stop device, and it is possible to immediately move to the unlocking operation of the electric lock. Is. Further, the activation unit may use the entire case as a touch sensor type switch.

Further, the activation unit may activate the function stop device by elastically tilting the thumb turn knob in the direction perpendicular to the axis. According to this, since the thumb turn knob and the activation unit can be integrated, the space of the electric lock control system can be saved.

Further, even if the starting portion does not have a push button structure in which the protruding state is automatically returned by an elastic force such as a spring force when pushed in, or a state change before and after the operation of a touch sensor type switch or the like. After activating the function stop device, if the automatic locking function is restored, the thumb turn picker will be automatically locked. Therefore, facility personnel can easily determine that the function stop device is not activated by looking at the thumb turn picker. can do. In this case, the thumb turn picking shall be accompanied by a change of appearance or a change of position with respect to the door surface in the locked state and the unlocked state. As a result, it is not necessary to separately provide a display function indicating that the function stop device has been activated, other than the state change associated with the locking / unlocking function of the electric lock picked by the thumb turn. In addition, the facility officials dare to indicate that the function stop device has been activated because the door is opened by turning the thumb turn knob immediately after performing an operation to activate the function stop device by pressing a push button or the like. Even if it is not present, there is no problem in implementing the electric lock control system according to the present invention. Examples of the display function include lighting of an LED lamp. By omitting such a display function, the electric lock control system can be simplified and power saving can be achieved. .. However, the effect of omitting such a display function does not exclude the display function in the electric lock control system according to the present invention.

Further, it is also preferable that the thumb turn picking is a crime prevention thumb turn picking that enables switching of the locked state of the electric lock on condition that a specific operation is performed.

Further, in the composite electric lock control system according to the present invention, a plurality of electric lock control systems according to any one of the above are provided on the door, and all of them are activated by activating at least one of the above-mentioned function stop devices. The automatic locking function of the electric lock is stopped, and the stopped automatic locking function is restored when the electric lock is locked by at least one of the thumb turn picking operations. And.

According to the present invention, even a door provided with an electric lock 3 having an automatic locking function can return to the inside of the door without being locked out even if the door is held with the key of the door and goes out. It does not reduce the security of the automatic locking function.

It is a block diagram of the electric lock control system 1 in the 3rd Embodiment.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. In the present specification and the drawings, components having substantially the same functional configuration are designated by the same reference numerals, so that duplicate description will be omitted.

In the first embodiment, the electric lock control system 1 shown in FIGS. 1 and 2 has an electric lock 3 installed inside the door end side of the door 2. The electric lock 3 has an automatic locking function A that automatically locks the door 2 when it senses that the door 2 is closed. In the present embodiment, the electric lock 3 includes a magnetic force switch 4 that senses the open / closed state of the door 2 by a magnetic force.

The door 2 is installed at a place that separates the inside and the outside of the site of the facility where only specific facility personnel can freely enter and exit. The facility includes, for example, a condominium, and the facility is a condominium. An example of the person concerned with the facility is a resident of a condominium.

Further, the electric lock 3 has a dead bolt 5 and a latch bolt 6 projecting toward the door end in the locked state, and in the locked state, the dead bolt 5 is inserted into the receiving 8 of the door frame 7 to lock the electric lock 3. The latch bolt 6 is interlocked with the handle 9, and when the electric lock 3 is unlocked and then the handle 9 is turned, the latch bolt 6 is pulled out from the receiver 10 and the door 2 can be opened. In the present embodiment, the automatic locking function A has a function of projecting the dead bolt 5 from the electric lock 3 by receiving a signal detected by the magnetic switch 4 that the door 2 is closed. The component of the electric lock control system according to the present invention is not limited to the above configuration of the automatic locking function A.

As shown in FIG. 3, a case 11 and a thumb turn device 13 provided with a thumb turn knob 12 projecting toward the inside of the facility are attached to the outer surface of the door 2 facing the inside of the facility. The thumb-turn device 13 has a thumb-turn knob 12 and a shaft 14 that penetrates the case 11 from the thumb-turn knob 12 toward the door 2. Further, the shaft 14 is inserted into the inside of the door 2 and connected to the internal mechanism of the electric lock 3. As a result, the dead bolt 5 can be manually infested from the door end surface 2a of the door 2 by rotating the thumb turn knob 12 around the axis.

As shown in FIG. 3, a lock cylinder 15 is attached to the outer surface of the door 2 outside the facility, which is the opposite surface of the thumb turn device 13. Normally, when the automatic locking function A is functioning, a person who intends to enter the facility from the outside of the facility turns the key inserted in the lock cylinder 15 to unlock the electric lock 3. You can open the door 2 and enter.

As shown by the alternate long and short dash line in FIG. 3, the case 11 is provided with a function stop device 16 capable of stopping the automatic locking function A while maintaining the locked / unlocked state of the electric lock 3. Further, a push button 17 is provided on the inner side surface of the facility of the case 11 as a starting portion of the function stop device 16. When the push button 17 is pressed, the automatic locking function A can be stopped by activating the function stop device 16.

Next, the operation of the electric lock control system 1 will be described. The following Steps 1 to 5 correspond to the flow chart of FIG.

When the automatic locking function A is operated in advance and the electric lock 3 is in the locked state, as shown in FIG. 4A, the automatic locking function A presses the push button 17 to activate the function stop device 16 (Step 1a). ) Stops (Step2a). That is, the electric lock 3 is maintained in the locked state. When the automatic locking function A is stopped, the thumb turn knob 12 is manually rotated by 90 ° (Step 3a) and the dead bolt 5 inserted in the receiver 8 is immersed in the door 2 from the door tip surface 2a. After the electric lock 3 is unlocked, the thumb turn knob 12 is manually rotated 90 ° counter-rotate again (Step 4) to maintain the electric lock 3 until it is locked.

A more specific example will be described. A facility official presses the push button 17 (Step 1a) to stop the automatic locking function A (Step 2a), and then turns the thumb turn knob 12 (Step 3a) to unlock the electric lock 3 inside the door 2. The door 2 can be opened by turning the handle 9 of the above, and the door 2 can be temporarily exited with the automatic locking function A stopped. When a person concerned with the facility goes out and releases his / her hand from the handle 9, the door 2 is closed by a door closer (not shown) or the like. Here, since the automatic locking function A of the door 2 is stopped, the dead bolt 5 remains immersed in the inside of the door 2, and the electric lock 3 maintains the unlocked state. Therefore, on the outside of the door 2, for example, when a facility person who has picked up mail from the mailbox tries to return from the door 2 to the inside of the facility, the door 2 can be opened by turning the handle 9 on the outside of the door 2. You can go inside the facility.

Then, the person concerned with the facility who entered the inside of the facility from the door 2 closes the door 2, rotates the thumb turn knob 12 by 90 ° counter-rotate (Step 4), and inserts the dead bolt 5 into the receiver 8 of the door frame 7 to obtain an electric lock. 3 can be manually locked. At this time, the automatic locking function A that senses that the thumb turn knob 12 has been counter-rotated is restored (Step 5).

It is preferable that the push button 17 has a structure in which the protruding state is automatically returned by an elastic force such as a spring force when the push button 17 is pushed. This eliminates the need for the operation of returning the state of the boost button 17 after activating the function stop device 16, and the operation of unlocking the electric lock 3 can be performed immediately. Further, the push button 17 may be a touch sensor type switch. If it is a touch sensor type switch, since the push button 17 does not change the mechanism, it is not necessary to return the state of the push button 17 after activating the function stop device 16, and the operation immediately proceeds to the unlocking operation of the electric lock 3. Because it can be done. Further, after the function stop device 16 is activated, if the automatic locking function A is restored, the thumb turn pick 12 is automatically locked. Therefore, if the facility personnel see the thumb turn pick 12, the function stop device 16 is not activated. It can be judged at a glance that it is. Here, the locked state of the thumb turn knob 12 means that the wide flat surface is horizontal, for example, as shown in FIGS. 1 to 3 or 6. On the other hand, when the thumb turn knob 12 is unlocked, it means that the wide flat surface in FIGS. 1 to 3 or 6 is vertical. Therefore, since the appearance state of the thumb turn picking 12 with respect to the door surface is different, the locked / unlocked state of the thumb turn picking 12 can be easily determined. As a result, it is not necessary to separately provide a display function indicating that the function stop device 16 has been activated, other than the state change associated with the locking / unlocking function of the thumb turn knob 12 for the electric lock 3. Immediately after the facility personnel perform an operation to activate the function stop device 16 by pressing a push button 17 or the like, the thumb turn knob 12 is turned to unlock and the door 2 is opened, so that the function stop device 16 is activated. Even if it is not intentionally shown, there is no problem in implementing the electric lock control system 1 according to the present invention. Examples of the display function include lighting of an LED lamp. By omitting such a display function, the electric lock control system 1 can be simplified and power saving can be achieved. be. However, the effect of omitting such a display function does not exclude the display function in the electric lock control system according to the present invention.

Here, when a person involved in the facility tries to temporarily exit the door 2, the thumb turn knob 12 may be rotated before the function stop device 16 is activated, and then the function stop device 16 may be activated. In such a case, as shown in FIG. 4B, the thumb turn knob 12 is rotated (Step 0b) before the function stop device 16 is activated to unlock the electric lock 3. Further, the push button 17 may be pressed to activate the function stop device 16 before the thumb turn knob 12 is counter-rotated (Step 1b).

In this case, when the function stop device 16 is activated, the automatic locking function A is stopped and the electric lock 3 is maintained in the unlocked state (Step 2b). Therefore, the facility personnel can temporarily go out of the door 2 with the automatic locking function A stopped by turning the handle 9 inside the door 2 to open the door 2. When a person concerned with the facility goes out and releases his / her hand from the handle 9, the door 2 is closed by a door closer (not shown) or the like. Here, since the automatic locking function A of the door 2 is stopped, the dead bolt 5 remains immersed in the inside of the door 2, and the electric lock 3 maintains the unlocked state. Therefore, on the outside of the door 2, for example, when a facility person who has picked up mail from the mailbox tries to return from the door 2 to the inside of the facility, the door 2 can be opened by turning the handle 9 on the outside of the door 2. You can go inside the facility.

Then, the person concerned with the facility who entered the inside of the facility from the door 2 closes the door 2, rotates the thumb turn knob 12 by 90 ° counter-rotate (Step 4), and inserts the dead bolt 5 into the receiver 8 of the door frame 7 to obtain an electric lock. 3 can be manually locked. At this time, the automatic locking function A that senses that the thumb turn knob 12 has been counter-rotated is restored (Step 5).

In order for the function stop device 16 to detect that the thumb turn knob 12 has been rotated or counter-rotated, as shown in FIG. 5, a state in which the thumb turn knob 12 is rotated with an electrical contact with the rotated thumb turn knob 12 is maintained. A contact S1 for detecting and a contact S2 for detecting a counter-rotated state having an electrical contact with the counter-rotated thumb turn knob 12 are provided. The contacts S1 and S2 transmit a signal to the function stop device 16 that the thumb turn knob 12 is in a rotated state or a counter-rotated state by electrical connection with the thumb turn knob 12, respectively. The function stop device 16 can receive a signal from the contact S1 or S2 and detect the rotational state of the thumb turn knob 12.

Here, when the facility personnel who have pushed the push button 17 and went out of the facility do not return for a certain period of time t or more, the function stop device 16 automatically locks by detecting the passage of the certain time t by the timer T. The function A may be restored. The automatic locking function A, which has returned after a lapse of a certain period of time t, projects the dead bolt 5 and inserts it into the receiver 8 to lock the electric lock 3. As a result, even if the push button 17 is erroneously pressed and the door 2 is opened, it is possible to prevent the electric lock 3 from being left in the unlocked state for a long time, so that the electric lock 3 is crime-prevented. It is possible to prevent deterioration of sex.

The function stop device 16 is provided with an arithmetic processing unit C and a storage device M. The arithmetic processing unit C can issue a stop command or the like for the automatic locking function A by activating the function stopping device 16, and can also issue a return command for the automatic locking function A. Further, the storage device M may store that the function stop device 16 is in the activated state and whether the thumb turn knob 12 is in the rotated state or the counter-rotated state. can. Further, the storage device M can store t for a certain period of time, and the arithmetic processing unit C can acquire the t for a certain period of time from the storage device M and issue a return command for the automatic locking function A through the control of the timer T. The fixed time t can be set to about 1 minute to 5 minutes.

On the other hand, if it is known in advance that there is no plan to go out from the door 2 and return for a while, the thumb turn knob 12 is turned to unlock the electric lock 3 without pressing the push button 17, and the door 2 is opened. Go outside. In this case, the automatic locking function A, which receives a signal from the magnetic switch 4 and senses that the door 2 is automatically closed by the door closer or the like described above, automatically projects the dead bolt 5 and the electric lock 3 Is locked. As a result, the door 2 cannot be opened simply by turning the handle 9 unless an unlocking operation such as inserting a key into the lock cylinder 15 is performed, so that the security function of preventing the intrusion of a suspicious person into the facility can be maintained. can. As an operation for unlocking the locked electric lock 3 from the outside of the facility, a personal identification number may be input to the personal identification number input device instead of the unlocking operation of inserting the key into the lock cylinder 15.

Further, as a second embodiment, as a specific operation, the thumb turn knob 12 uses an anti-rotation switch 18 provided on the surface of the knob portion when the electric lock 3 is unlocked, as shown in FIG. It is preferable that the security thumb turn knob is used so that the locked state of the electric lock cannot be switched by rotating the shaft unless it is pressed.

Since the thumb turn knob 12 is provided with the anti-rotation switch 18, even if a suspicious person tries to rotate the thumb turn knob 12 around the axis between the door 2 and the door frame 7 by using some tool, the anti-rotation switch 18 is operated. By holding the thumb turn knob 12, the thumb turn knob 12 does not rotate around the axis, and the electric lock 3 cannot be unlocked. Therefore, since the thumb turn picking 12 is a crime prevention thumb turn picking, the crime prevention function of the electric lock 3 can be further improved.

Further, as described above, since the function stop device 16 has only the function of stopping the automatic locking function A, the function stop device 16 is provided so that the thumb turn picker 12 is a crime prevention thumb turn picker. It does not decrease. Therefore, by using the thumb turn picking 12 as a crime prevention thumb turn picking and further providing a function stopping device 16 having only a function of stopping the automatic locking function A, it is easy to use even when going out for a short time and has a high crime prevention function. The electric lock control system 1 provided with the above can be realized.

Further, as a third embodiment, a composite electric lock control system in which a plurality of electric locks 3 and thumb turn devices 13 are provided on the door 2, and an electric lock control system 1 is provided on each electric lock 3. It is also preferable to configure. The reason why a plurality of electric locks 3 are provided is that the crime prevention property can be improved as compared with the case where one electric lock 3 is provided.

As a specific example, FIG. 7 shows a case where the door 2 is provided with two electric locks 3 and a thumb turn device 13, and the function of the electric lock control system 1 in this case will be described.

In FIG. 7, the door 2 is provided with an electric lock 3a, a case 11a, a thumb turn device 13a having a thumb turn knob 12a on the upper side, and a push button 17a on the surface of the case 11a, and stops functioning inside the case 11a. The device 16a is built in. On the other hand, on the lower side of the door 2, a thumb turn device 13b having an electric lock 3b, a case 11b, a thumb turn knob 12b, and a push button 17b are provided on the surface of the case 11b, and a function stop device 16b is provided inside the case 11b. It is built-in.

Here, the function stop devices 16a and 16b are connected by a signal line 19 capable of transmitting and receiving electrical signals to and from each other, as shown in FIGS. 7 and 8. The signal line 19 may be either wired or wireless.

Since the function stop devices 16a and 16b are connected by the signal line 19, when the push button 17a is pressed, both the function stop devices 16a and 16b are activated. Also, when the push button 17b is pressed, both the function stop devices 16a and 16b are activated. As a result, in the third embodiment, the operation of stopping the automatic locking function A by the facility personnel can be completed by pressing either the push button 17a or 17b once, and it takes time to open the door 2. Can be minimized.

After pressing either the push button 17a or 17b once to stop the automatic locking function A, it is necessary to manually operate all the thumb turn knobs 12a and 12b in order to open the door 2, but after that, the facility The operation of the electric lock control system 1 from temporarily going out to the outside and returning to the inside of the facility is the same as in the case of the first embodiment.

However, in order for the facility personnel who have returned to the inside of the facility to restore the automatic locking function A, either one of the thumb turn pickers 12a and 12b is manually counter-rotated to either the electric lock 3a or the electric lock 3b. It is preferable that it is sufficient to perform the operation of locking the pad. According to this, the function stop devices 16a and 16b transmit a signal that one of the electric locks 3 has been locked to each other via the signal line 19, and the electric lock 3 that has not been manually locked is automatically locked. The function A is automatically restored, and the corresponding electric lock 3 can also be locked. Therefore, it is possible to save labor because the operation for returning all the automatic locking functions A can be realized only by the manual operation of one thumb turn knob 12.
