  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Exemplary embodiments of a lock device and a locking / unlocking method according to the present invention are explained in detail below with reference to the accompanying drawings. In the following embodiment, the main lock used for the purpose of restricting the entry (room entry) of non-related persons who do not have the key, and unauthorized entry of unauthorized intruders by making unauthorized unlocking and opening difficult. This is an example in which the present invention is applied to a lock device having two lock mechanisms called auxiliary locks used for the purpose of inhibiting and preventing. That is, the lock device is installed at the doorway, the first lock mechanism of the present invention is applied to the auxiliary lock, and the second lock mechanism of the present invention is applied to the main lock. However, the present invention is not limited to this, and if the lock device is provided with a plurality of locks, the present invention uses the first lock as the first lock mechanism and the second lock as the second lock mechanism among the plurality of locks. Can be applied.

(Embodiment 1)
The auxiliary lock according to the present embodiment is normally unlocked and is unlocked in conjunction with the security setting of the security device. For this reason, the auxiliary lock is a lock mechanism that does not require a separate locking / unlocking operation when an authorized user enters or leaves the building. When the person forgets to release the security, the person moves from the unlocked state to the locked state to prevent intrusion by an unauthorized intruder, or prompts the authorized user to release the security.

  First, the difference between the roles of the main lock and the auxiliary lock will be described. As described above, the main lock is used for the purpose of restricting the entrance (entrance) of non-related persons who do not have the key. In other words, the main lock only needs to be able to inform the good third party that entry is prohibited except for those concerned by locking the doorway. On the other hand, the auxiliary lock is used for the purpose of deterring and preventing unauthorized entry by unauthorized intruders by making unauthorized unlocking and opening difficult.

  In other words, the purpose of installing the auxiliary lock is to expect the following effects. First, by combining it with the main lock, the labor and time required for various non-destructive illegal unlocking means (picking, thumb-turning, etc.) is doubled. Secondly, it makes it physically difficult to perform unauthorized opening means (prying open, breaking the lock, etc.) that involve the destruction of the doorway and the lock device. Thirdly, in addition to the difficulty of unauthorized unlocking by the installation of an auxiliary lock, the intruder feels that the resident's awareness of crime prevention is high, and urges them to lose their criminal intention and not to commit a crime. . In other words, if you only want to prevent people who do not have a key from entering the building, only the main lock is sufficient, but it is effective to install an auxiliary lock to prevent and control unauthorized unlocking and opening. is there.

  Here, as the frequency of crimes, non-destructive illegal unlocking means (picking, thumb-turn turning, etc.) are overwhelmingly larger than illegal opening means (peg opening, unlocking, etc.) accompanied by destruction of doors and locks. For this reason, the auxiliary lock of the present embodiment is in an unlocked state when an authorized user enters the building mainly for the purpose of preventing unauthorized unlocking means, and when unauthorized unlocking is attempted. If you have forgotten the release of security or security, change from the unlocked state to the locked state. The auxiliary lock according to the present embodiment will be described below.

  FIG. 1 is a diagram illustrating an entire entrance door provided with the lock device according to the first embodiment. In FIG. 1, it is the front view which looked at the entrance door 4 from the exterior of a room. The doorway door 4 is provided with a lock mechanism 100 in which a main lock 2A is disposed on the upper side and an auxiliary lock 2B is disposed on the lower side. On the outer side of the entrance door 4 is a cylinder 30a that is rotated by a user inserting a key to rotate the deadlocking latch bolt 10 in the main lock 2A. A lever handle 70a for receiving an operation force from the user is provided.

  FIG. 2 is an explanatory diagram of a configuration of the lock device according to the first embodiment. As shown in FIG. 2, the lock device 100 according to the present embodiment is mainly composed of a front 1 and a lock mechanism 2 installed at an entrance door, and the upper side of the lock mechanism 2 is a main lock 2A (first lock). 2 lock mechanism parts), the lower side is an auxiliary lock 2B (first lock mechanism part).

  The main lock 2A includes a control unit 510, an external power supply unit 520, and an operation unit 501, and the auxiliary lock 2B includes a control unit 511, an external power supply unit 521, and an operation unit 502. The operation unit 501 and the operation unit 502 are connected to a security device 500 provided in the monitoring area. Details of the front 1 and the lock mechanism 2 will be described later.

  The security device 500 monitors (guards) the monitoring area where the entrance door is installed. When an abnormality occurs in the monitoring area, the abnormality detection information indicating that the abnormality has been detected in the monitoring center that is the report destination. It is a report. When the monitoring center receives the notification of the abnormality detection information from the security device in the monitoring area, the monitoring center gives an instruction to the waiting security guard to go to the monitoring area where the abnormality is detected, and if necessary, the police And report to related organizations such as fire departments. In the present embodiment, the lock device 100 is connected to the security device 500 by wire, but may be configured to be connected by wireless communication.

  Next, the operation unit 501, the control unit 510, and the external power feeding unit 520 in the main lock 2A will be described.

  The operation unit 501 is installed outside the monitoring area near the entrance door, and receives an input of a user ID (second user identification information) unique to a user such as a security guard. For example, a numeric keypad or a contact type Or what is necessary is just to identify users, such as a non-contact-type card reader, a touch panel, and biometric information readers, such as a fingerprint, an iris, and a vein. The operation unit 501 is not used daily by a user in the monitoring area. When the monitoring area user is absent, the operation unit 501 is a security guard who arrives when an abnormality occurs in the monitoring area, or a security guard who visits the inspection area. This is used for an operation for a member to lock and unlock the main lock 2A without using a key or the like.

  The controller 510 controls energization of a solenoid 90 (described later). That is, control unit 510 performs user authentication by checking whether the user ID received by operation unit 501 is a user ID predetermined in a storage unit (not shown) or the like, and the user When the authentication is successful, the solenoid 90 is energized, and the solenoid 90 is de-energized after a predetermined time has elapsed. In addition, the control unit 510 normally supplies the power supplied to the monitoring area or the like to the operation unit 501, the solenoid 90, or the like. For example, when power cannot be supplied due to a power failure or the like, the external power supply unit When the power supplied by 520 is supplied to the operation unit 501 and the user authentication of the user ID received from the operation unit 501 is successful, the power supplied by the external power supply unit 520 is supplied to the solenoid 90 and energized. .

  The external power supply unit 520 supplies power to the control unit 510 independently, and corresponds to, for example, a battery. When the control unit 510 cannot receive power from a general-purpose power supply due to a power failure or the like, the power from the external power supply unit 520 is supplied to the control unit 510. It is possible to control energization.

  Next, the operation unit 502, the control unit 511, and the external power feeding unit 521 in the auxiliary lock 2B will be described.

  The operation unit 502 is installed outside the monitoring area in the vicinity of the entrance door, and accepts settings such as a security state or a security release state, which is a security mode of the security device 500. Similar to the operation unit 501, it is only necessary to accept various security mode settings such as a numeric keypad, a contact or non-contact card reader, a touch panel, a biological information reader such as a fingerprint, an iris, and a vein. The operation unit 502 receives an input of a user ID (first user identification information) unique to a user (security guard or the like).

  Here, the security mode is a mode that determines whether or not to notify the reporting destination when abnormality is detected in the monitoring area, or whether or not notification to the monitoring area is possible, and the operation of the security device when an abnormality is detected. This is the mode to decide. The security mode has a plurality of modes depending on the availability of notification, the notification destination, the presence / absence of notification to the monitoring area, and the like, and representative security modes include a security state and a security release state.

  The security state is a security mode that is mainly set when the user (resident) is out of the office and needs security, and when the security device receives a detection signal issued when an abnormality is detected by the sensor. In this state, an alarm (abnormality detection information) for notifying the monitoring center of an abnormality is notified. In some cases, it is notified that an abnormality has been detected in the monitoring area where the security device is installed. This is for the purpose of intimidating an intruder or for the purpose of prompting an alarm release operation in the case of misinformation.

  The security release state is a security mode that is set mainly when the user is at home and does not need security. Even if the security device receives a detection signal that is detected when an abnormality is detected by the sensor, monitoring is performed. The alarm (abnormality detection information) is not reported to the center, and it is not determined that there is an abnormality in the monitoring area. This is because even if an abnormality is detected by the sensor (detection of the presence of a person, detection of opening / closing of a door), it is determined that a user at home has been detected.

  The control unit 511 controls energization to a solenoid 190 (described later). That is, the control unit 511 energizes the solenoid 190 when accepting the setting for setting the security mode of the security device 500 to the security state by the operation unit 502, and when receiving the setting for setting the security mode to the security release state. The solenoid 190 is deenergized. In addition, the control unit 511 performs user authentication by checking whether the user ID received by the operation unit 502 is a user ID predetermined in a storage unit (not shown) or the like, and the user When the authentication is successful, the solenoid 190 is de-energized, and when the user authentication is not successful, the solenoid 190 is energized. In addition, the control unit 511 normally supplies power supplied to the monitoring area or the like to the operation unit 502, the solenoid 190, or the like. For example, when power cannot be supplied due to a power failure, the external power supply unit The power supplied by the external power supply unit 521 is supplied to the solenoid 190 when the power supplied from the external power supply unit 521 is supplied to the operation unit 502 and set in the guard state or when the user authentication of the user ID is not successful. To energize.

  The external power supply unit 521 supplies power independently to the control unit 511, and corresponds to, for example, a battery. When the control unit 511 cannot receive power from a general-purpose power source due to a power failure or the like, the control unit 511 is supplied with power from the external power supply unit 521. It is possible to control energization.

  Next, details of the front 1 and the lock mechanism 2 will be described. FIG. 3 is an explanatory diagram illustrating details of the lock control device according to the first embodiment. As shown in FIG. 3, the lock device 100 according to the present embodiment includes a front 1 and a lock mechanism 2, and the lock mechanism 2 has a main lock 2 </ b> A arranged on the upper side and an auxiliary lock on the lower side. 2B is arranged.

It is mainly equipped with. In the main lock 2A according to the present embodiment, the manual operation unit 30 is a mechanical locking / unlocking unit that mechanically locks / unlocks by the operation force from the user, and the solenoid 90 is electrically unlocked by energization / non-energization. It demonstrates as an electric locking / unlocking part which locks. The handle portion 70 is also provided in common with the auxiliary lock 2B.

  The deadlocking latch bolt 10 is mainly composed of a tip portion 12, a shaft portion 11, and a stopper 13, and can be inserted into and removed from a hole portion (not shown) provided on the wall surface of the entrance / exit. The deadlocking latch bolt 10 has both a function of a dead bolt that locks the doorway in a fully-locked state and a function of a latch bolt that locks the doorway in an empty-locked state. It is a bolt that can be unlocked.

  Here, the full lock state (locked state) of the main lock is a state in which the doorway cannot be opened even if the lever handle 70a (see FIG. 1) provided on the doorway is operated. That is, the tip of the deadlocking latch bolt 10 that has passed through the opening of the front 1 is inserted into a hole (not shown) provided in the wall surface of the doorway so as to face the main lock 2A, and the deadlocking latch bolt 10 is It is in a state where it is held in the hole and cannot move. In addition, the main lock 2A in the lock mechanism 2 of FIG. 3 is in the final locked state.

  Further, the empty lock state (unlockable state) of the main lock means that the door is temporarily tightened so that the door cannot be opened due to wind pressure or the like, and if the lever handle 70a provided on the door is operated, dead The locking latch bolt 10 is in a movable state. That is, the end of the deadlocking latch bolt 10 is in a state where it can be pulled out through the front 1 from a hole (not shown) provided in the wall surface of the doorway so as to face the main lock 2A. When the provided lever handle 70a is operated, the deadlocking latch bolt 10 is pulled out from the hole on the wall surface of the entrance / exit after passing through the front 1 by the operating force received from the user via the handle 70 (described later). It is in a state where it can be opened and the entrance door can be opened.

  Further, the unlocked state of the main lock is a state where the lever handle 70a provided on the doorway is operated and can be opened simply by pressing the doorway. That is, by transmitting the operating force received by the lever handle 70a to the deadlocking latch bolt 10, the deadlocking latch bolt 10 is moved to the inside of the doorway door to the tip and can be opened simply by pressing the doorway door. .

  First, referring to FIG. 3 and FIG. 9, the operation when the handle 70 is operated in the lock device 100 in which the main lock 2A shown in FIG. explain. FIG. 9 is a diagram showing a case where the handle portion is operated in the lock device shown in FIG. 3.

  The main lock 2 </ b> A shown in FIG. 3 is in the final locked state because the connecting lever 60 and the shaft portion 11 of the deadlocking latch bolt 10 are separated in a disengaged state. In this state, when the operation force from the user to the lever handle fitted in the lever handle hole 72 is received, the handle portion 70 rotates in the R4 direction, and the handle receiving member 71 of the handle portion 70 and the connecting portion are connected. The connecting lever 60 connected at 61 moves to the state of the main lock 2A in FIG. That is, in the state of the main lock 2A in FIG. 3, even if the operating force from the user to the lever handle is received, the connecting lever 60 is not engaged with the shaft portion 11 of the deadlocking latch bolt 10. 70 and the connecting lever 60 are idled without moving the deadlocking latch bolt 10. Accordingly, since the main lock 2A is in a state in which the deadlocking latch bolt 10 cannot move, the main lock 2A does not enter the idle lock state and remains in the lock state even when the lever handle is operated. Note that the connecting lever 60 in this case is not related to the locking / unlocking operation, but since the pressing from the protrusion 54 of the locking lever 50 is released by moving, the connecting lever 60 is slightly rotated in the R3 direction by the spring.

  The auxiliary lock 2B shown in FIG. 3 is in a lockable state because the security mode is set to the security state and the connecting lever 160 and the shaft 111 of the dead bolt 110 are engaged. In this state, when the operation force from the user to the lever handle is received, the handle portion 70 rotates in the R4 direction, and the connecting lever 160 connected to the handle receiving member 73 of the handle portion 70 by the connecting portion 161 is moved. The dead bolt 110, which has moved and pressed the shaft 111 by the connecting lever 160, moves in the F direction, and the auxiliary lock 2B in FIG. Therefore, when the lever handle is operated, the auxiliary lock 2B moves to the locked state because the dead bolt 110 moves.

  In other words, in the lock device 100 of FIG. 3, when the lever handle is rotated, the deadlocking latch bolt 10 of the main lock 2A maintains the fully-tightened locked state, and the deadbolt 110 of the auxiliary lock 2B moves from the lockable state. In the lock apparatus 100 of FIG. 9, the main lock 2A and the auxiliary lock 2B are locked, and the doorway door is not opened.

  Further, in the state of the lock device 100 of FIG. 9, when the user releases his / her hand from the lever handle, the handle portion 70 is rotated in the direction opposite to the R4 direction by the biasing force of the spring. Then, the connecting lever 60 connected to the handle receiving member 71 and the connecting portion 61 moves, and the connecting lever 160 connected to the handle receiving member 73 and the connecting portion 161 moves to return to the state shown in FIG.

  Next, by operating the manual operation unit 30 from the lock device 100 in which the main lock 2A shown in FIG. 3 is in the final lock state and the auxiliary lock 2B is in the lockable state, the main lock 2A is in the empty lock state. The operation (mechanical unlocking) in the case of being made will be described with reference to FIG. 3 and FIG. FIG. 10 is a diagram showing a lock device including a main lock 2A in an empty lock state and an auxiliary lock 2B in a lockable state. Further, in FIG. 10, the auxiliary lock 2B remains in the lockable state because the security mode remains set to the security state. Here, when the main lock 2A is changed from the fully locked state to the empty locked state and the auxiliary lock 2B remains in the guard state, for example, unauthorized unlocking such as picking or thumb turn by an unauthorized intruder is performed. Or a case where a legitimate user has operated the manual operation unit 30 in a state in which he / she has forgotten to set the security mode to the security release state.

  In the main lock 2A in the fully-locked state shown in FIG. 3, when the user receives an operation force to rotate the manual operation unit 30 in the R1 direction, the thumb turn hub 31 rotates in the R1 direction in conjunction with the manual operation unit 30. Move. When the thumb turn hub 31 rotates, the thumb turn hub 31 presses the inclined portion 42a of the slider 40 upward, and the slider 40 moves upward (direction A). At this time, since the protruding portion 51 of the locking lever 50 is in contact with the lower inner wall surface of the hole 41, the protruding portion 51 is pressed by the lower inner wall surface as the slider 40 moves upward. By the movement of the portion 51, the locking lever 50 rotates in the R2 direction around the fulcrum 52. When the locking lever 50 rotates in the R2 direction, the projection 54 moves in the inner direction (upward direction) of the dead locking latch bolt 10 and releases the pressure on the connecting lever 60. When the pressing from the locking lever 50 is released, the connecting lever 60 is rotated in the R3 direction by the biasing force of a spring (illustrated), and the engaging portion 63 is engaged with the shaft portion 11 of the deadlocking latch bolt 10. Then, as shown in FIG. 10, the main lock 2A is in an empty lock state.

  At this time, the auxiliary lock 2B shown in FIG. 3 is in a lockable state because the security mode is set to the security state and the connecting lever 160 and the shaft 111 of the dead bolt 110 are engaged. ing. Since the security mode is still set to the security state, the auxiliary lock 2B shown in FIG. 10 is in a lockable state as in FIG.

  Next, with reference to FIGS. 10 and 11, the operation when the handle portion 70 is operated in the lock device 100 in which the main lock 2 </ b> A shown in FIG. I will explain. FIG. 11 is a diagram illustrating a case where the handle portion is operated in the lock device illustrated in FIG. 10.

  The main lock 2 </ b> A shown in FIG. 10 is in a state where the connecting lever 60 and the shaft portion 11 of the deadlocking latch bolt 10 are engaged with each other, so that the main lock 2 </ b> A is loosely locked by mechanical unlocking. In this state, when an operation force from the user to the lever handle is received, the handle portion 70 is rotated in the R4 direction, and the handle portion 70 and the connecting lever 60 are connected by the connecting portion 61. Therefore, the connecting lever 60 Moves in the B direction. When the connecting lever 60 moves in the B direction, the deadlocking latch bolt 10 engaged with the engaging portion 63 by the shaft portion 11 moves in the B direction against the urging force of the spring 15, and the tip portion 12 is inserted into the lock mechanism 2. When the leading end 12 of the deadlocking latch bolt 10 is moved until it is completely inserted into the lock mechanism 2, the main lock 2A does not project the deadlocking latch bolt 10 from the front 1, as shown in FIG. State and unlocked state.

  The auxiliary lock 2B shown in FIG. 10 is in a lockable state because the security mode is set to the security state and the connecting lever 160 and the shaft 111 of the dead bolt 110 are engaged. In this state, when the operation force from the user to the lever handle is received, the handle portion 70 rotates in the R4 direction, and the connecting lever 160 connected to the handle receiving member 73 of the handle portion 70 by the connecting portion 161 is moved. The dead bolt 110 that has moved and pressed the shaft 111 by the connecting lever 160 moves in the direction F, and the auxiliary lock 2B in FIG. Therefore, when the lever handle is operated, the auxiliary lock 2B moves to the locked state because the dead bolt 110 moves.

  That is, in the lock device 100 of FIG. 10, when the lever handle is rotated, the deadlocking latch bolt 10 of the main lock 2A is changed from the idle lock state to the unlocked state, but the dead bolt 110 of the auxiliary lock 2B is Since the lockable state is changed to the locked state, in the lock lock device 100 of FIG. 11, the main lock 2A is unlocked, the auxiliary lock 2B is locked, and the entrance door is not opened. Therefore, for example, even if the main lock 2A is illegally unlocked from the manual operation unit 30 that is operated by inserting a key, the auxiliary lock 2B is not unlocked unless it is set to the security release state, and unauthorized entry is made. Can be prevented.

  Next, when the security mode is set from the security state to the security release state by the operation unit 502 from the lock device 100 in which the main lock 2A shown in FIG. 3 is in the fully locked state and the auxiliary lock 2B is in the lockable state. Will be described with reference to FIGS. 3 and 12. FIG. FIG. 12 is a diagram showing a lock apparatus including a main lock 2A in a fully-locked state and an auxiliary lock 2B in an unlocked state. Here, the main lock 2A remains in the fully locked state.

  The auxiliary lock 2B shown in FIG. 3 receives the setting of the security release state by the operation unit 502, and when the security mode of the security device 500 is set from the security state to the security release state, the control unit 511 deactivates the solenoid 190. The iron core 192 moves in the E direction. When the iron core 192 moves in the E direction, the connecting portion 153 connected to the iron core 192 is pulled in the E direction, and the locking lever 150 rotates in the R6 direction. When the locking lever 150 rotates in the R6 direction, the protrusion 154 moves upward and presses the connecting lever 160. When the locking lever 150 is pressed, the connecting lever 160 rotates about the connecting portion 161 in the R7 direction, and the engaging portion 163 releases the engagement of the dead bolt 110 with the shaft portion 111. FIG. As shown, the auxiliary lock 2B is unlocked.

  Next, the main lock 2A is unlocked and locked by operating the manual operation unit 30 from the lock device 100 in which the main lock 2A shown in FIG. 12 is in the fully locked state and the auxiliary lock 2B is in the unlocked state. The operation (mechanical unlocking) in the case of being made will be described with reference to FIG. 12 and FIG. FIG. 13 is a diagram showing a lock apparatus including a main lock 2A in an empty lock state and an auxiliary lock 2B in an unlock state. Here, the operation of changing the main lock 2A from the fully-locked locked state to the empty-locked locked state by the manual operation unit 30 is performed by moving the main lock 2A shown in FIGS. Since this is the same as the operation for setting the state, the description is omitted.

  Next, with reference to FIGS. 13 and 14, the operation when the handle 70 is operated in the lock device 100 in which the main lock 2A shown in FIG. I will explain. FIG. 14 is a diagram showing a case where the handle portion is operated in the lock device shown in FIG. 13.

  The main lock 2A shown in FIG. 13 is in an idle locked state by mechanical unlocking, and the connecting lever 60 and the shaft portion 11 of the deadlocking latch bolt 10 are engaged. In this state, the operation when receiving the operation force from the user to the lever handle is the same as the operation of the main lock 2A when receiving the operation force from the user to the lever handle in FIGS. Since it is the same, description is abbreviate | omitted.

  The auxiliary lock 2B shown in FIG. 13 is disengaged between the connecting lever 160 and the shaft 111 of the dead bolt 110 when the security mode is set from the security state to the security release state and the solenoid 190 is deenergized. In this state, it is unlocked. In this state, when the operation force from the user to the lever handle is received, the handle portion 70 rotates in the R4 direction, and the connecting lever 160 connected to the handle receiving member 73 of the handle portion 70 by the connecting portion 161 is moved. It moves and it will be in the state of the auxiliary | assistant lock 2B of FIG. That is, since the connecting lever 160 is not engaged with the shaft portion 111 of the dead bolt 110 even when an operation force from the user to the lever handle is received in the state of the auxiliary lock 2B in FIG. The connecting lever 160 will idle without moving the dead bolt 110. Therefore, the auxiliary lock 2B remains in the unlocked state even when the lever handle is operated because the dead bolt 110 is incapable of moving.

  That is, in the lock device 100 of FIG. 13, when the lever handle is rotated, the deadlocking latch bolt 10 of the main lock 2A is changed from the idle lock state to the unlocked state, and the deadbolt 110 of the auxiliary lock 2B is unlocked. Therefore, in the lock lock device 100 of FIG. 14, the main lock 2A and the auxiliary lock 2B are unlocked, and the doorway is opened.

  In the lock device 100 shown in FIG. 14, when the doorway is opened, the trigger head 85 released from the pressure on the wall surface of the doorway is moved in the direction C by the biasing force of the spring and fixed to the trigger head 85. The U-shaped member 86 is also moved in the C direction. When the U-shaped member 86 moves in the C direction, the end portion 87 presses the protrusion 82 of the latch hold 80 in the C direction, and the latch hold 80 rotates in the R5 direction.

  When the user releases the lever handle after the entrance door is opened, the handle portion 70 is rotated in the opposite direction to the R4 direction by the biasing force of the spring, and is connected to the handle portion 70 and the connecting portion 61. The connecting lever 60 is also moved in the direction opposite to the B direction. When the connecting lever 60 moves in the direction opposite to the B direction, the deadlocking latch bolt 10 that has been engaged with the engaging portion 63 by the shaft portion 11 and moved in the B direction is moved in the B direction by the urging force of the spring 15. And move in the opposite direction.

  At this time, the handle portion 70 rotates in the direction opposite to the R4 direction and returns to the position of the handle portion 70 in the idle lock state in FIG. 13, but the deadlocking latch bolt 10 is in the empty lock state in FIG. Will not return. This is because the stopper 13 comes into contact with the locking portion 83 of the latch hold 80 rotated in the R5 direction while the deadlocking latch bolt 10 is biased by the spring 15 and is moving in the direction opposite to the B direction. 13, and does not return to the position of the deadlocking latch bolt 10 in the loosely locked state in FIG. 13, but only the substantially triangular prism-shaped portion at the tip of the tip 12 of the deadlocking latch bolt 10 is projected from the front 1 It becomes. Thus, the deadlocking latch bolt 10 is temporarily inserted into the lock mechanism 2 by the pressing force from the wall surface of the entrance / exit to the substantially triangular prism-shaped portion when the entrance / exit door is closed without receiving the operating force from the lever handle. The entrance door will be closed.

  Further, when the doorway is closed, the trigger head 85 is pressed from the wall surface of the doorway so that the trigger head 85 moves in the direction opposite to the C direction against the urging force of the spring, and is U-shaped fixed to the trigger head 85. The member 86 also moves in the direction opposite to the C direction. When the U-shaped member 86 moves in the direction opposite to the C direction, the pressing in the C direction against the protrusion 82 of the latch hold 80 by the end portion 87 is released, and the latch hold 80 is in the direction opposite to the R5 direction by the biasing force of the spring. To turn. Then, the deadlocking latch bolt 10 once inserted into the lock mechanism 2 by the pressing force from the wall surface of the doorway moves in the direction opposite to the B direction by the biasing force of the spring 15, and the latch hold 80 moves in the direction opposite to the R5 direction. Since the stopper 13 is not locked to the locking portion 83 due to the rotation, the distal end portion 12 is inserted into the hole of the wall surface of the entrance and exit, and the lock is locked.

  As described above, the setting of the security release state is accepted by the operation unit 502, and the security mode is set from the security state to the security release state by the control unit 511, so that the auxiliary lock 2B is changed from the lockable state to the unlocked state and is manually operated. When the main lock 2A is changed from the fully-locked locked state to the empty-locked locked state (mechanical unlocking) by the operation from the section 30, the entrance door can be opened by operating the lever handle. That is, even if the lever handle is operated without setting to the security release state, or the lever handle is operated without performing the operation from the manual operation unit 30, the entrance door is not opened.

  Next, when the solenoid 90 is energized from the lock device 100 in which the main lock 2A shown in FIG. 3 is in the fully locked state and the auxiliary lock 2B is in the lockable state, the main lock 2A is brought into the empty locked state. The operation when the security mode is set from the security state to the security release state by the operation unit 502 will be described with reference to FIGS. FIG. 15 is a diagram showing a lock device including a main lock 2A in an empty lock state and an auxiliary lock 2B in an unlock state.

  The case where the main lock 2A is brought into the unlocked state by energization means, for example, that an abnormality has occurred in the monitoring area, and the monitoring center that has received the notification of the abnormality detection information directs the waiting security guard to the monitoring area. This is the case. When a security guard who does not have the key of the doorway installed in the monitoring area rushes, the security guard inputs the user ID of the security guard to the operation unit 501 installed near the doorway. When the operation unit 501 receives the user ID, the control unit 510 performs user authentication by checking whether the received user ID is a user ID predetermined in the storage unit or the like, and uses the user ID. When the person authentication is successful, the solenoid 90 is energized.

  In the main lock 2A in the fully-locked state shown in FIG. 3, when the solenoid 90 is energized, the iron core 92 moves in the D direction. When the iron core 92 moves in the D direction, the connecting portion 53 connected to the iron core 92 is pulled in the D direction, and the locking lever 50 rotates in the R2 direction. When the locking lever 50 rotates in the R2 direction, the projection 54 moves in the inner direction (upward direction) of the dead locking latch bolt 10 and releases the pressure on the connecting lever 60. When the pressing from the locking lever 50 is released, the connecting lever 60 is rotated in the R3 direction by the urging force of the spring, and the engaging portion 63 is engaged with the shaft portion 11 of the dead locking latch bolt 10, and FIG. As shown in FIG. 15, the main lock 2 </ b> A is in an empty lock state. Here, since the protrusion 51 is in contact with the lower inner wall surface of the hole 41 of the slider 40, when the locking lever 50 is rotated in the R2 direction by energizing the solenoid 90, the protrusion 51 does not contact the lower inner wall surface of the hole 41 and moves upward in the hole 41. For this reason, the slider 40 does not move upward in conjunction with the rotation of the locking lever 50 in the R2 direction. As shown in FIGS. 3 and 15, the slider 40 is loosely tightened even in the fully locked state. The same position is maintained even in the locked state.

  The auxiliary lock 2B shown in FIG. 3 receives the setting of the security release state by the operation unit 502, and when the security mode of the security device 500 is set from the security state to the security release state, the control unit 511 deactivates the solenoid 190. The iron core 192 moves in the E direction. When the iron core 192 moves in the E direction, the connecting portion 153 connected to the iron core 192 is pulled in the E direction, and the locking lever 150 rotates in the R6 direction. When the locking lever 150 rotates in the R6 direction, the protrusion 154 moves upward and presses the connecting lever 160. When pressed from the locking lever 150, the connecting lever 160 rotates about the connecting portion 161 in the R7 direction, and the engaging portion 163 releases the engagement of the dead bolt 110 with the shaft portion 111. FIG. As shown, the auxiliary lock 2B is unlocked.

  Next, with reference to FIGS. 15 and 16, the operation when the handle 70 is operated in the lock device 100 in which the main lock 2A shown in FIG. I will explain. FIG. 16 is a diagram showing a case where the handle portion is operated in the lock device shown in FIG. 15.

  The main lock 2 </ b> A shown in FIG. 15 is in an unlocked and locked state by electrical unlocking, and the connecting lever 60 and the shaft portion 11 of the deadlocking latch bolt 10 are engaged. In this state, the operation when receiving the operation force from the user to the lever handle is the same as the operation of the main lock 2A when receiving the operation force from the user to the lever handle in FIGS. Since it is the same, description is abbreviate | omitted.

  The auxiliary lock 2B shown in FIG. 15 is in a state in which the engagement between the connecting lever 160 and the shaft 111 of the dead bolt 110 is released because the security mode is set to the security release state and the solenoid 190 is de-energized. Therefore, it is in an unlocked state. In this state, when the operation force from the user to the lever handle is received, the operation of the auxiliary lock 2B when receiving the operation force from the user to the lever handle in FIGS. Since it is the same, description is abbreviate | omitted.

  That is, in the lock device 100 of FIG. 15, when the lever handle is rotated, the deadlocking latch bolt 10 of the main lock 2A is changed from the idle lock state to the unlocked state, and the dead bolt 110 of the auxiliary lock 2B is unlocked. Therefore, in the lock lock device 100 of FIG. 16, the main lock 2A and the auxiliary lock 2B are unlocked, and the doorway is opened.

  In this way, the setting of the security release state is accepted by the operation unit 502, the security mode is set from the security state to the security release state by the control unit 511, and the auxiliary lock 2B is changed from the lockable state to the unlocked state, and the operation unit The lever handle is operated when the main lock 2A is changed from the fully locked state to the empty locked state (electrical unlocking) by performing user authentication with the user ID received from 501 and energizing the solenoid 90. The doorway can be opened. That is, even if the lever handle is operated without setting to the security release state, or the lever handle is operated without receiving the user ID from the operation unit 501, the entrance door is not opened.

  As described above, in the operation of the lock apparatus 100, when the operation unit 502 receives the setting of the security mode of the security state or the security release state, and when the control unit 511 receives the setting of the security state by the operation unit 502, the solenoid When the setting of energizing 190 and accepting the security release state is received, the auxiliary lock 2B is locked or unlocked by deenergizing the solenoid 190. On the other hand, the solenoid 190 may be energized or de-energized depending on whether or not the user authentication by the user ID received by the operation unit 502 is successful, so that the auxiliary lock 2B can be locked or unlocked.

  Specifically, the operation in the case where the security mode is set from the security state to the security release state by the operation unit 502 from the lock device 100 in which the main lock 2A is in the fully locked state and the auxiliary lock 2B is in the lockable state. (See FIGS. 3 and 12).

  When the auxiliary lock 2B shown in FIG. 3 receives a user ID (first user identification information) by the operation unit 502, user authentication is performed by the user ID received by the control unit 511, and the user authentication is performed. If successful, the solenoid 190 is de-energized and the iron core 192 moves in the E direction. When the iron core 192 moves in the E direction, the connecting portion 153 connected to the iron core 192 is pulled in the E direction, and the locking lever 150 rotates in the R6 direction. When the locking lever 150 rotates in the R6 direction, the protrusion 154 moves upward and presses the connecting lever 160. When the locking lever 150 is pressed, the connecting lever 160 rotates about the connecting portion 161 in the R7 direction, and the engaging portion 163 releases the engagement of the dead bolt 110 with the shaft portion 111. FIG. As shown, the auxiliary lock 2B is unlocked. Moreover, the operation | movement to the unlocking state of the auxiliary | assistant lock 2B in FIG. 15 is also the same.

  In this way, the input of the user ID is received by the operation unit 502, and when the user authentication is successful by the control unit 511, the auxiliary lock 2B is changed from the lockable state to the unlocked state by deenergizing the solenoid 190, In addition, when the main lock 2A is changed from the fully locked state to the empty locked state by mechanical operation from the manual operation unit 30 (mechanical unlocking), the entrance door can be opened by operating the lever handle. That is, even when the lever handle is operated when the user authentication is not successful or the lever handle is operated without performing the operation from the manual operation unit 30, the entrance door is not opened.

  Further, when the user ID is input by the operation unit 502 and the user authentication is successful by the control unit 511, the solenoid 190 is deenergized so that the auxiliary lock 2B is changed from the lockable state to the unlocked state, and the operation is performed. The lever handle is operated when the main lock 2A is changed from the fully locked state to the empty locked state (electrical unlocking) by performing user authentication with the user ID received from the unit 501 and energizing the solenoid 90. By doing so, the doorway can be opened. In other words, when the user authentication is not successful, even if the lever handle is operated or the lever handle is operated without accepting the user ID from the operation unit 501, the entrance door is not opened. .

  Next, whether the main lock 2A and the auxiliary lock 2B can be locked or unlocked will be described. FIG. 17 is a diagram showing whether the main lock 2A and the auxiliary lock 2B can be locked or unlocked.

  As shown in FIG. 17, the main lock 2 </ b> A accepts the user ID when the operation by the manual operation unit 30 of the mechanical locking / unlocking unit is performed and the user ID by the operation unit 501 of the electric locking / unlocking unit for user authentication. If successful, the operation from the fully locked state (locked state) to the empty locked state (unlockable state) or vice versa can be performed. On the other hand, the main lock 2A, when accepting the setting of the security mode by the operation unit 502 and accepting the user ID by the operation unit 502 and succeeding in the user authentication, the main lock 2A is empty from the final lock state (lock state). The operation to the locked state (unlockable state) or the opposite operation cannot be performed.

  In addition, as shown in FIG. 17, the auxiliary lock 2 </ b> B receives the user ID when the manual operation unit 30 of the mechanical locking / unlocking unit is operated and the user ID by the operation unit 501 of the electric locking / unlocking unit. When the authentication is successful, the operation from the fully locked state (lockable state) to the empty lock state (unlocked state) or the opposite operation cannot be performed. On the other hand, when the auxiliary lock 2B accepts the setting of the security mode by the operation unit 502, and receives the user ID by the operation unit 502 and succeeds in the user authentication, the auxiliary lock 2B starts from the final locking state (lockable state). The operation to the idle lock state (unlock state) or vice versa can be performed.

  The above is the case where the user ID received from the operation unit 501 (referred to as user ID-A) and the user ID received from the operation unit 502 (referred to as user ID-B) are different. Therefore, when the user ID-A and the user ID-B are the same, that is, when the user authentication is performed by the control units 510 and 511 using the same user ID, the same user ID is used. The locking / unlocking operation of the main lock 2A and the auxiliary lock 2B can be performed (see “A = B in FIG. 17”).

  As described above, the auxiliary lock 2B in the lock lock device 100 according to the first embodiment is in an unlocked state at normal time, and when an illegal act is performed due to forgetting setting to the unauthorized unlocking or security release state, etc. When the lever handle 70a is operated, the deadbolt 110 is changed from the unlocked state to the locked state, and the unlocked state is maintained when normal unlocking is performed. Therefore, when a regular user enters or exits, the entrance door is locked only with the main lock, so the entrance door can be locked and unlocked with a single locking and unlocking operation. Convenience can be improved without forcing. In addition, when an unauthorized act such as unauthorized unlocking by an unauthorized intruder is performed, the entrance door is locked by the main lock 2A and the auxiliary lock 2B. Security can be improved. In addition, even if an authorized user does not set the security release state, even if the unlocking from the manual operation unit 30 is attempted with the key, the entrance door is not opened, and the authorized user is made aware of the forgotten release of the security. In addition, it is possible to reduce false alarms to the monitoring center due to forgetting to cancel the security.

  Further, since the auxiliary lock 2B can be locked and unlocked by moving the deadbolt 110 according to the setting of the security state or the security release state in the security device 500, a security company or the like that provides a security service can use the auxiliary lock 2B. It becomes unnecessary to receive the key, and the burden of key management and the operation of the security service can be reduced.

(Modification of Embodiment 1)
