  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.

(First embodiment)
In the lock device according to the present embodiment, when an abnormality occurs in a monitoring area of a building or the like in which a security device is installed, a guard who rushes unlocks the doorway installed in the monitoring area The door can be unlocked even if you do not have a key, etc., and you can unlock the door using a key, etc. This is a lock device having both a lock part (electric lock).

  In a lock device equipped with a conventional mechanical lock and electric lock, the electric lock usually serves to limit the entry (entrance) to the monitoring area of a person other than the authorized user, and is always locked. Must be used in. In other words, the electric lock is unlocked only when the data of the admitted person registered in advance by IC (Integrated Circuit) card, non-contact card, biometric authentication, etc. is successful, and the door is temporarily opened and closed. After that, it returns to the locked state again so that it can be determined whether or not the person who intends to enter next can enter the monitoring area. Therefore, both mechanical unlocking and electrical unlocking must structurally have a function of returning to the locked state at all times.

  However, the lock device according to the present embodiment is based on the premise that an electric lock is used when a security guard enters a monitoring area where an abnormality has occurred. In other words, the lock device according to the present embodiment has a security device installed in the monitoring area, and if any abnormality occurs in the monitoring area when there is no contractor of the security device (user of the monitoring area), Personnel can unlock the entrance door and enter the monitoring area without receiving a metal key in advance. Further, the locking / unlocking of the lock device performed by the contractor is interlocked and unlocked only at the time of the locking / unlocking operation using the metal key, similarly to the lock device of the mechanical lock not provided with the electric lock. Therefore, as a contractor, there is no difference from a general lock device with only a mechanical lock, and it is not necessary to always be locked at a normal time. For example, if an electric lock is used in a general household, etc., when it comes out of the house (surveillance area) around a residence such as a garden or a garbage dump, it enters the house again. This is because it is necessary to unlock after performing the operation, which is a complicated operation. Therefore, the lock device according to the present embodiment does not need to return to the locked state even after the doorway door is once opened and closed when mechanical unlocking is performed.

  FIG. 1 is an explanatory diagram illustrating a configuration of a lock apparatus according to the first embodiment. As shown in FIG. 1, the lock device 100 according to the present embodiment mainly includes a front 1 and a lock mechanism 2 installed at an entrance door, a security device 500, and an operation unit 501.

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 by wire, but may be configured to be connected by wireless communication.

  The operation unit 501 is installed outside the monitoring area in the vicinity of the entrance door, and receives an input of a user ID (user identification information) unique to a user such as a security guard. Any device can be used as long as the user is specified, such as a contact card reader, a touch panel, a biometric information reader such as a fingerprint, an iris, or 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. It is used for an operation for a member to lock and unlock the lock apparatus 100 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 normal times, the power supplied to the monitoring area or the like is supplied 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 control unit 510 may 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, details of the front 1 and the lock mechanism 2 will be described. FIG. 2 is an explanatory diagram illustrating details of the lock apparatus according to the first embodiment. As shown in FIG. 2, the lock device 100 according to the present embodiment includes a front 1 and a lock mechanism 2, and the lock mechanism 2 includes a deadlocking latch bolt 10, a manual operation unit 30, and a slider. 40, a locking lever 50, a connecting lever 60, a handle 70, a latch hold 80, a trigger head 85, and a solenoid 90 are mainly provided. In the lock lock device 100 according to the present embodiment, the manual operation unit 30 is a mechanical locking / unlocking unit that mechanically locks / unlocks by operating 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 front 1 is a plate-shaped metal plate that has an opening (not shown) through which the deadlocking latch bolt 10 and the trigger head 85 enter and exit and covers the side surface of the lock mechanism 2.

When the lock device 100 is installed in the doorway, the lock mechanism 2 is embedded in the doorway, and the front 1 is visible on the side surface of the doorway.

  The deadlocking latch bolt 10 is mainly composed of a front end portion 12, a shaft portion 11, and a stopper 13, and functions as a deadbolt that locks the doorway door in a fully-locked state, and a doorway door lock-in state. It also functions as a latch bolt that makes it possible to lock both of the above. Here, the final lock state is a state where the door cannot be opened even if a lever handle or a door knob provided on the door is operated, and passes through the opening of the front 1 to the wall of the door. The tip of the deadlocking latch bolt 10 has been inserted, and the deadlocking latch bolt 10 has become immovable. Further, the idle lock state means that the door is temporarily tightened so that the door is not opened by wind pressure or the like, and the deadlocking latch bolt 10 is movable, passes through the front 1 and passes from the wall of the doorway to the deadlocking latch. The tip of the bolt 10 can be pulled out, and when a lever handle or door knob provided on the entrance door is operated, an operating force (first operating force) from the user received through the handle portion 70 (described later) The deadlocking latch bolt 10 is pulled out from the wall surface of the entrance / exit after passing through the front 1, and the entrance / exit door can be opened. Note that the lock mechanism 2 in FIG. 2 is in a fully-locked state.

  The shaft portion 11 of the deadlocking latch bolt 10 is made of a metallic material having a hollow inside and having an upper portion and a lower portion opened. Further, a tip end 12 is connected to one end face of the shaft portion 11, and this tip end 12 is a portion that is inserted into an opening (not shown) of the front 1 when the locking is performed. It is made of a substantially triangular prism-shaped metallic material. A cylindrical iron core 14 is connected to the other end face of the shaft portion 11 so as to be movable with respect to the shaft portion 11. The end surface of the iron core 14 opposite to the end surface connected to the shaft portion 11 is fixed to the frame portion of the lock mechanism 2, and when the deadlocking latch bolt 10 moves in the B direction, Is to be inserted. A spring 15 is provided around the iron core 14, and the deadlocking latch bolt 10 is urged by the spring 15 in the direction opposite to the normal B direction.

Here, of the operation force from the manual operation unit 30, the operation force (second operation force) for rotating the thumb turn hub 31 in the R1 direction is to change the doorway from the fully locked state to the empty lock state. The operating force (third operating force) for rotating the thumb turn hub 31 in the direction opposite to the R1 direction changes the doorway door from the empty lock state to the final lock state. Therefore, the R1 direction (first direction) is the rotational direction of the thumb turn hub 31 from the locked state of the doorway to the empty lock state, and the opposite direction (second direction) to the R1 direction (second direction) is the lock lock of the doorway. The thumb turn hub 31 is rotated in the locking direction from the state to the final locking state. The manual operation unit 30 is used daily by a user in the monitoring area, and a user who goes out locks and unlocks the lock device 100 from an external cylinder, or a user who returns home from an internal thumb turn. The lock device 100 is used for an operation for locking and unlocking. That is, the locking / unlocking operation by the operation from the manual operation unit 30 is mainly used in the lock lock device 100 rather than the locking / unlocking operation by the operation from the operation unit 501 described above.

  The slider 40 moves in the direction A (the third direction) which is the upper side in FIG. 2 or the direction (the fourth direction) opposite to the A direction which is the lower side in FIG. 2 in conjunction with the rotation of the manual operation unit 30. Therefore, by transmitting the operation force from the manual operation unit 30 from the user to the deadlocking latch bolt 10, the lock lock device 100 is set in the empty lock state or the final lock state. That is, the A direction (third direction) is the moving direction of the slider 40 accompanying mechanical unlocking, and the opposite direction (fourth direction) to the A direction is the moving direction of the slider 40 accompanying mechanical locking. FIG. 3A is a front view of the slider. FIG. 3B is a side view of the slider as viewed from the V1 side in FIG.

  Further, as shown in FIGS. 4A to 4D, the locking lever 50 is provided with a protruding portion 54 that protrudes in a plate shape at the upper end portion. When rotating in the direction opposite to the R2 direction by the biasing force of the spring, the connecting lever 60 is pressed. That is, when the slider 40 moves in the direction opposite to the A direction and the pressing from the slider 40 to the protrusion 51 is released, the locking lever 50 is rotated in the direction opposite to the R2 direction by the spring biasing force, The protrusion 54 moves outward (downward) of the deadlocking latch bolt 10 and presses the connecting lever 60. On the other hand, when the protrusion 51 is pressed in the A direction by moving the slider 40 in the A direction, the locking lever 50 rotates in the R2 direction against the biasing force of the spring, and the protrusion 54 The latch bolt 10 moves inward (upward) to release the pressure on the connecting lever 60. In the lock device 100 of FIG. 2, the locking lever 50 is rotated in the direction opposite to the R2 direction, and the protrusion 54 is moved in the outward direction (downward) of the deadlocking latch bolt 10.

  Moreover, the locking lever 50 is connected with the iron core 92 of the solenoid 90 in the space where the lower part is opened by the left connecting portion 53 in FIG. 4-1. When the solenoid 90 is energized and the iron core 92 moves in the D direction, the locking lever 50 is pulled in the D direction in conjunction with the iron core 92 and rotated in the R2 direction, so that the protrusion 54 is deadlocked latch bolt 10. Is moved in the inner direction (upward), and the pressure on the connecting lever 60 is released. On the other hand, when the solenoid 90 is deenergized and the suction force of the iron core 92 in the direction D by the solenoid 90 is released, the urging force of a spring (not shown) provided around the shaft of the fulcrum 52 of the locking lever 50 is released. As a result, the iron core 92 moves in the direction opposite to the D direction, the locking lever 50 rotates in the direction opposite to the R2 direction, and the protruding portion 54 moves in the outward direction (downward) of the deadlocking latch bolt 10 to connect. The lever 60 is pressed.

  When the locking lever 50 is rotated by energizing or de-energizing the solenoid 90 as described above, the protrusion 51 connected to the slider 40 moves in the hole 41 but contacts the hole 41. Without it, the slider 40 is not interlocked. That is, as shown in FIGS. 2 and 3-1, the hole 41 of the slider 40 is formed in such a size that the protrusion 51 can move, so that the locking lever 50 is interlocked with the iron core 92 of the solenoid 90. Even if the projection rotates, the protrusion 51 only moves in the hole 41 and the slider 40 does not interlock.

  The connecting lever 60 rotates in the R3 direction or in the direction opposite to the R3 direction around the connecting portion 61 that is rotatably connected to the handle receiving member 71 of the handle portion 70. By transmitting the operating force received from the user through the deadlocking latch bolt 10, the deadlocking latch bolt 10 is moved to open the doorway. FIG. 5 is a front view of the connecting lever. The connecting lever 60 is a plate-like member made of a metallic material, and is normally urged in the R3 direction by a spring (not shown) provided around the shaft of the connecting portion 61. Further, the connecting lever 60 is formed with a recessed engaging portion 63 so as to engage with the end portion of the shaft portion 11 of the deadlocking latch bolt 10.

  Further, the connecting lever 60 is rotated in the R3 direction by the biasing force of the spring when the locking lever 50 is rotated in the R2 direction and the pressing from the protrusion 54 is released. In this case, a space is provided in the shaft portion 11 of the deadlocking latch bolt 10 by the protrusion 51 moving in the inner direction (upward direction) of the deadlocking latch bolt 10. Then, the connecting lever 60 enters the space by rotating in the R3 direction, and rotates until the engaging portion 63 reaches the position of the end portion of the shaft portion 11, and the engaging portion 63 is turned to the deadlocking latch bolt 10. The shaft portion 11 is engaged.

  On the other hand, when the locking lever 50 rotates in the direction opposite to the R2 direction and is pressed by the projection 54, the connecting lever 60 rotates in the direction opposite to the R3 direction against the urging force of the spring. In this case, the protrusion 51 moves in the outward direction (downward) of the deadlocking latch bolt 10 so that the space provided in the shaft portion 11 of the deadlocking latch bolt 10 disappears. Then, the connecting lever 60 is pushed out of the space by rotating in the direction opposite to the R3 direction, and the entire connecting lever 60 is completely out of the shaft portion 11 of the deadlocking latch bolt 10, so that the engaging portion 63. Is disengaged from the shaft portion 11 of the deadlocking latch bolt 10. 2 is in a state in which the engagement between the engagement portion 63 and the deadlocking latch bolt 10 is released.

  The connecting lever 60 transmits the operating force from the user received from the handle portion 70 to the deadlocking latch bolt 10 by the engaging portion 63 engaging with the shaft portion 11 of the deadlocking latch bolt 10, and the deadlock latch bolt 10. The doorway door is opened by moving the locking latch bolt 10. The state in which the connecting lever 60 and the deadlocking latch bolt 10 are engaged with each other is a state in which the doorway can be opened, and thus is in an empty lock state. Further, the connecting lever 60 releases the engagement between the engaging portion 63 and the shaft portion 11 of the deadlocking latch bolt 10, so that the user's operating force received from the handle portion 70 is applied to the deadlocking latch bolt 10. By making the transmission impossible and making the deadlocking latch bolt 10 immovable, the doorway cannot be opened, that is, closed. The state in which the engagement between the connecting lever 60 and the deadlocking latch bolt 10 is released is a state in which the doorway cannot be opened, and thus is in the final locking state.

  The handle portion 70 includes a handle receiving member 71 and a lever handle (not shown), and the lever handle is inserted into and fitted into a square lever handle hole 72 provided in the handle receiving member 71. Further, the handle receiving member 71 is provided with a spring (not shown) around the lever handle hole 72 and is biased in the direction opposite to the R4 direction by the biasing force of the spring. When the operating force (first operating force) for rotating the lever handle in the R4 direction is received from the user in order to open the door that is locked in the closed state, the handle portion 70 opens the lever handle hole 72. It rotates in the R4 direction as an axis. When the user releases the lever handle after opening the door, the handle portion 70 is rotated in the direction opposite to the R4 direction by the biasing force of the spring and returned to the position shown in FIG.

  In the case where the latch door 80 is closed from the opened state, only the substantially triangular prism-shaped portion at the tip of the tip 12 of the deadlocking latch bolt 10 is protruded from the front 1 when the door is closed. The stopper 13 of the deadlocking latch bolt 10 that moves in the direction opposite to the direction is stopped by stopping the stopper 13 on the locking portion 83, and the fulcrum 81 fixed to the frame portion of the lock mechanism 2 is used as an axis. It can be turned. The latch hold 80 is moved in the direction opposite to the R5 direction by being biased by a spring (not shown) provided around the fulcrum 81, and in FIG. The movement is locked. The latch-hold 80 is pressed by the end portion 87 of a U-shaped member 86 (described later) moving in the C direction, and rotates in the R5 direction against the urging force of the spring. The latch hold 80 stops the movement of the deadlocking latch bolt 10 by the locking portion 83 when rotated in the R5 direction. In the lock device 100 of FIG. 2, the latch hold 80 is in a state moved in the direction opposite to the R5 direction.

  The trigger head 85 is formed of a substantially triangular prism-shaped metallic material, and prevents the slider 40 from moving so that the lock door is not locked when the doorway is opened. A U-shaped member 86 formed of a metallic material having a U-shaped cross section is fixed to the end of the trigger head 85 opposite to the front 1 side. The trigger head 85 is normally urged in the C direction by a spring (not shown) provided on the U-shaped member 86 side. However, when the doorway is closed, the trigger head 85 is pressed by the wall surface of the doorway. It is pressed in the opposite direction. Then, the trigger head 85 moves in the C direction while the doorway door is opened and the pressure from the wall surface of the doorway is released, and the doorway is closed and pressed against the wall surface of the doorway in the direction opposite to the C direction. It moves and is inserted into the lock mechanism 2. A hole is formed on the upper surface of the U-shaped member 86, and when the door is closed, that is, when the trigger head 85 is inserted into the lock mechanism 2, the hole is moved to the slider. Forty latching portions 43 can pass through. Further, when the U-shaped member 86 moves in the C direction in conjunction with the movement of the trigger head 85 in the C direction, the end portion 87 presses the protrusion 82 of the latch hold 80 in the C direction. In the lock device 100 of FIG. 2, the trigger head 85 is in a state moved in the direction opposite to the C direction.

  The solenoid 90 is a kind of electromagnet and converts electrical energy into mechanical energy by the action of electromagnetic induction. The solenoid 90 is mainly composed of a solenoid main body 91 and an iron core 92. The solenoid body 91 is provided with a hole, and an iron core 92 is inserted into the hole. The upper portion of the iron core 92 is rotatably connected to the locking lever 50 by a connecting portion 53.

  When the solenoid 90 is energized by the control unit 510, the iron core 92 moves in the direction of insertion into the hole, that is, the D direction in FIG. 2, and moves the connecting portion 53 in the D direction. Further, when a predetermined time elapses after being energized, the control unit 510 deenergizes the solenoid 90, and when the suction force of the iron core 92 in the direction D by the solenoid 90 is released, the locking lever 50 Due to the urging force of a spring (not shown) provided around the axis of the fulcrum 52, the iron core 92 moves in the direction opposite to the D direction, and the connecting portion 53 moves in the direction opposite to the D direction.

  The lock device 100 of the present embodiment is configured as described above. Here, compared with the structure of the conventional lock apparatus, the structure of the lock apparatus 100 of this Embodiment is demonstrated. In a conventional lock device equipped with a mechanical lock and an electric lock, both the mechanical unlocking and the electrical unlocking are structurally equipped with a function to return to a locked state at all times, so the doorway is opened. Every time it was closed, it returned to the locked state. If it does so, the movement of the deadlocking latch volt | bolt by opening / closing of an entrance / exit door, the mechanical locking / unlocking part, and the electrical locking / unlocking part all have to be interlocked. In other words, even when the deadlocking latch bolt is moved by the mechanical lock and the locking / unlocking is performed, the electrical locking / unlocking part is interlocked, and conversely, the deadlocking latch bolt is moved by the electric lock and unlocking is performed. However, the mechanical locking / unlocking part is interlocked. For example, the mechanical locking / unlocking part, the electrical locking / unlocking part, and the deadlocking latch bolt are arranged in a series of substantially circular shapes, and all are interlocked. It was in composition. Therefore, in the conventional lock device, in order to perform the same operation in the electrical locking and unlocking unit and the mechanical locking and unlocking unit, for example, a connecting member for connecting the electrical locking and unlocking unit and the mechanical locking and unlocking unit is separately provided. As a result, the number of members of the lock device increases and the structure becomes complicated, and the lock device itself is excessively expensive.

  Therefore, as described above, the lock device 100 of the present embodiment is based on the premise that the user of the monitoring area uses the mechanical locking / unlocking unit as a main body, and the security guard uses the electrical locking / unlocking unit. Therefore, it is not necessary to configure a function to always return to the locked state when unlocked by the mechanical locking / unlocking part, and only the operation of the mechanical locking / unlocking part or the operation of the electrical locking / unlocking part is used. It is set as the structure which can lock. That is, the lock device 100 of the present embodiment does not have a configuration in which the movement of the deadlocking latch bolt, the mechanical locking / unlocking portion, and the electrical locking / unlocking portion are all interlocked, and the mechanical locking / unlocking portion Instead of requiring a connecting member for connecting the electrical locking / unlocking part, the locking lever 50 and the connecting lever 60 are respectively connected to the mechanical locking / unlocking part (manual operation part 30) and the electrical locking / unlocking part (solenoid 90). The lock device 100 is locked and unlocked by operating from the above. Specifically, when the locking lever 50 is rotated by locking / unlocking from the electrical locking / unlocking portion, the protrusion 51 that connects the slider 40 and the locking lever 50 can move without interlocking the slider 40. Such a hole 41 of the slider 40 is provided. Accordingly, the number of members of the lock device 100 can be reduced and the structure can be simplified, and the lock itself having a mechanical lock and an electric lock can be made cheaper than a conventional lock device having a mechanical lock and an electric lock. It can be configured.

  Next, the operation of the lock device 100 will be described. In addition, when operating the manual operation unit 30 (mechanical locking / unlocking unit) to bring the lock apparatus 100 into a full-locked state or an empty-locked state, mechanical locking / unlocking is performed, and a solenoid 90 (electrical locking / unlocking unit). The case where the lock device 100 is brought into the full-locked state or the empty-locked locked state by energization / non-energization is referred to as electrical locking / unlocking.

  First, with reference to FIGS. 2 and 6, an operation when the handle portion 70 is operated in the lock-lock device 100 in the final lock state shown in FIG. 2 will be described. FIG. 6 is a diagram illustrating a case where the handle portion is operated in the lock apparatus in the final locked state according to the first embodiment.

  Since the lock device 100 shown in FIG. 2 is in the final lock state, the connecting lever 60 and the shaft portion 11 of the deadlocking latch bolt 10 are separated from each other 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 lock device 100 of FIG. That is, in the state of the lock device 100 of FIG. 2, the handle lever is not engaged with the shaft portion 11 of the deadlocking latch bolt 10 even if the operating force from the user to the lever handle is received. 70 and the connecting lever 60 are idled without moving the deadlocking latch bolt 10. Therefore, since the lock device 100 is in a state in which the deadlocking latch bolt 10 is not movable, the lock device 100 is not locked in an empty state and the doorway door is not opened. 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.

  In the state of the lock device 100 in FIG. 6, 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 urging force of the spring. The connected connecting lever 60 moves to return to the state of FIG.

  Next, FIG. 2 and FIG. 7 will be described with respect to the operation (mechanical unlocking) in the case where the lock device 100 in the fully-locked state shown in FIG. The description will be given with reference. FIG. 7 is a diagram illustrating the lock device in an empty lock state according to the first embodiment.

  In the lock device 100 in the fully-locked state shown in FIG. 2, when an operation force for rotating the manual operation unit 30 in the R1 direction is received from the user, 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. 7, the lock lock device 100 is in an empty lock state.

  Next, referring to FIGS. 7, 8, and 9, the operation in the case where the doorway door is opened by operating the handle portion 70 from the lock device 100 in the empty lock state shown in FIG. 7. explain. FIG. 8 is a diagram illustrating a case where the handle portion is operated in the lock-lock device in the empty lock state according to the first embodiment. FIG. 9 is a diagram illustrating the lock device in the state where the doorway door is open according to the first embodiment.

  The lock device 100 shown in FIG. 7 is in an unlocked and 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, 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. Then, when the tip 12 of the deadlocking latch bolt 10 is moved until it is completely inserted into the lock mechanism 2, the deadlocking latch bolt 10 is not projected from the front 1 as shown in FIG. The door can be opened.

  In the lock device 100 shown in FIG. 8, when the doorway is opened, the trigger head 85 released from the pressure from the wall surface of the doorway is moved in the C direction by the biasing force of the spring and is fixed to the trigger head 85. The U-shaped member 86 also moves 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. 7, 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. 7 and does not return to the position of the deadlocking latch bolt 10 in the loosely locked state in FIG. 7, and only the substantially triangular prism-shaped portion at the front end of the front end portion 12 of the deadlocking latch bolt 10 as shown in FIG. It will be in the state protruded from 1. 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. Therefore, the stopper 13 is not locked to the locking portion 83, so that the distal end portion 12 is inserted into the wall surface of the entrance and exits, and the lock is locked (see FIG. 7).

  Next, referring to FIG. 7 and FIG. 2 for the operation (mechanical locking) in the case of being brought into the final locking state by operating the manual operation unit 30 from the lock device 100 in the empty locking state shown in FIG. To explain.

  In the lock device 100 in the lock state shown in FIG. 7, when an operation force for rotating the manual operation unit 30 in the direction opposite to the R1 direction is received from the user, the thumb turn hub 31 is connected to the manual operation unit 30 in the R1 direction. It rotates in the opposite direction. When the thumb turn hub 31 rotates, the thumb turn hub 31 presses the inclined portion 42b of the slider 40 downward, and the slider 40 moves downward, which is opposite to the A direction. When the slider 40 moves downward, the projection 51 of the locking lever 50 connected to the hole 41 is released from the pressing (no longer coming in contact) from the lower inner wall surface of the hole 41, and the locking lever 50 is released from the spring. It is rotated in the direction opposite to the R2 direction by the urging force. When the locking lever 50 rotates in the direction opposite to the R2 direction, the projecting portion 54 moves outward (downward) of the deadlocking latch bolt 10 and presses the connecting lever 60. When pressed from the locking lever 50, the connecting lever 60 rotates in the direction opposite to the R3 direction against the biasing force of the spring, and the engaging portion 63 engages with the shaft portion 11 of the deadlocking latch bolt 10. Is released, and the lock lock device 100 enters the final lock state as shown in FIG.

  As described above, in the mechanical locking / unlocking operation by the operation from the manual operation unit 30, even when the lock apparatus 100 is changed from the fully-locked locked state to the empty-locked locked state and the entrance door is once opened and then closed, the lock-unlocked device is locked. Returns to the state but does not return to the fully locked state. That is, when changing from the empty lock state to the final lock state, it is necessary to change to the final lock state by performing an operation from the manual operation unit 30.

  Next, the operation (electrical unlocking) when the lock device 100 in the fully-locked state shown in FIG. 2 is brought into the idle-locked state by energizing the solenoid 90 will be described with reference to FIGS. Will be described with reference to FIG. FIG. 10 is a diagram illustrating the lock device in an empty lock state according to the first embodiment.

  The case where the lock apparatus 100 is unlocked by energization is, for example, a case where an abnormality occurs in the monitoring area, and the monitoring center that has received the notification of the abnormality detection information directs the waiting guard to the monitoring area. . 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.

  When the solenoid 90 is energized, the iron core 92 moves in the direction D in the lock-lock device 100 in the fully-locked state shown in FIG. 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. 10, the lock device 100 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. 2 and 10, the slider 40 is loosely tightened even in the fully locked state. The same position is maintained even in the locked state.

  Next, with reference to FIG. 10, FIG. 11 and FIG. 12, the operation in the case where the doorway door is opened by operating the handle portion 70 from the lock device 100 in the closed state shown in FIG. explain. FIG. 11 is a diagram illustrating a case where the handle portion is operated in the lock-lock device in the empty lock state according to the first embodiment. FIG. 12 is a diagram illustrating the lock device in the state in which the doorway door is open according to the first embodiment.

  The lock device 100 shown in FIG. 10 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. The opening of the doorway in this state is the same as the opening of the doorway in an empty locked state by mechanical unlocking. That is, when the operation force from the user to the lever handle is received, the handle portion 70 is rotated in the R4 direction, the connecting lever 60 is moved in the B direction, and the deadlocking latch bolt 10 is also moved in the B direction. The distal end portion 12 is inserted into the lock mechanism 2. Then, when the leading end 12 of the deadlocking latch bolt 10 is moved until it is completely inserted into the lock mechanism 2, the deadlocking latch bolt 10 is not projected from the front 1 as shown in FIG. The door can be opened.

  In the lock device 100 shown in FIG. 11, when the doorway is opened, the trigger head 85 moves in the C direction, the U-shaped member 86 also moves in the C direction, and the end 87 is the protrusion 82 of the latch hold 80. Is pressed in the C direction, and the latch hold 80 rotates in the R5 direction. When the user releases the lever handle after the doorway is opened, the handle portion 70 is rotated in the direction opposite to the R4 direction, and the connecting lever 60 is moved in the direction opposite to the B direction. The bolt 10 moves in the direction opposite to the B direction.

  Then, as in the case of opening the door in mechanical unlocking, the handle portion 70 returns to the position of the handle portion 70 in the empty lock state in FIG. 10, but the deadlocking latch bolt 10 is latched and held by the stopper 13. Since it is locked by coming into contact with the locking portion 83 of 80, it does not return to the idle locking state in FIG. 10, but has a substantially triangular prism shape at the tip of the tip portion 12 of the deadlocking latch bolt 10 as shown in FIG. Only the portion is protruded from the front 1.

  Further, when the doorway is closed, the trigger head 85 moves in the direction opposite to the C direction and the U-shaped member 86 is also moved in the direction opposite to the C direction as in the case of closing the doorway in mechanical unlocking. The end portion 87 releases the pressing in the C direction on the protrusion 82 of the latch hold 80, and the latch hold 80 rotates in the direction opposite to the R5 direction. Then, the deadlocking latch bolt 10 once inserted into the lock mechanism 2 moves in the direction opposite to the direction B, and the distal end portion 12 is inserted into the wall surface of the entrance / exit to be in an empty lock state (see FIG. 10).

  Next, referring to FIG. 10 and FIG. 2 for the operation (electrical locking) when the lock device 100 in the empty lock state shown in FIG. 10 is brought into the full lock state by deenergizing the solenoid 90. To explain.

  In the lock device 100 in the lock-locked state shown in FIG. When the suction force is released, the iron core 92 moves in the direction opposite to the direction D by the biasing force of a spring (not shown) provided around the shaft of the fulcrum 52 of the locking lever 50, and the locking lever 50 It is rotated in the direction opposite to the R2 direction by the biasing force. When the locking lever 50 rotates in the direction opposite to the R2 direction, the projecting portion 54 moves outward (downward) of the deadlocking latch bolt 10 and presses the connecting lever 60. When pressed from the locking lever 50, the connecting lever 60 rotates in the direction opposite to the R3 direction against the biasing force of the spring, and the engaging portion 63 engages with the shaft portion 11 of the deadlocking latch bolt 10. Is released, and the lock lock device 100 is fully locked as shown in FIG.

  As described above, in the electrical locking by the solenoid 90 being de-energized, after a predetermined time has elapsed, the lock lock device 100 is idled without the user performing another operation again. The locked state returns to the final locked state. In other words, simply by performing an operation for setting the lock state in the fully-locked state, the lock-in state is returned to the lock-in-lock state after entering the lock-in-lock state.

  In addition, when the predetermined predetermined time has passed when the lock device 100 is in an unlocked and locked state by electrical unlocking and the doorway door is opened by operating the lever handle. However, the solenoid 90 is de-energized and the locking lever 50 tries to rotate in the direction opposite to the R2 direction. In this case, the rotation of the locking lever 50 in the direction opposite to the R2 direction is temporarily prevented by contacting the tip 12 of the deadlocking latch bolt 10. Then, when the doorway is closed and the leading end 12 of the deadlocking latch bolt 10 is inserted into the wall surface of the doorway and the lock lever 50 is once locked, the locking lever 50 once blocked is opposite to the R2 direction. , The lock lock device 100 enters the final lock state as described above.

  As described above, the lock lock device 100 according to the present embodiment allows the user ID such as the security guard to receive the user ID in the operation unit 501 without receiving the key for unlocking the entrance door of the monitoring area in advance. The door can be locked and unlocked simply by entering the key, reducing the burden of securing and managing the door door key storage, as well as processing cylinders and thumb turns to insert the door door key, etc. Maintenance work becomes unnecessary. Further, there is no need to take a configuration in which the movement of the deadlocking latch bolt 10, the locking / unlocking by the manual operation unit 30, and the locking / unlocking by the solenoid 90 are all interlocked. In addition, the lock itself having a mechanical lock and an electric lock can be made smaller than a conventional lock apparatus having a mechanical lock and an electric lock. When changing to 100, the processing of the entrance door is not required.

  In addition, since power can be supplied from the external power supply unit 520 to the control unit 510, the door can be locked and unlocked even when power cannot be supplied, such as during a power failure. Furthermore, since the deadlocking latch bolt 10 can perform the final locking and the empty locking, it is not necessary to perform both locking with separate bolts, and the configuration of the lock lock device 100 can be simplified. In addition, the manual operation unit 30 is provided with a thumb turn hub 31 that rotates in conjunction with a cylinder or thumb turn operated by the user and presses the slider 40. Regardless of the electrical locking and unlocking used, the mechanical door can be locked and unlocked by the operation of the thumb turn hub 31.

In the electrical unlocking, the lock device according to the first embodiment is to unlock the lock device by energizing the solenoid when the user ID received from the operation unit is successfully authenticated. However, in this embodiment, the user ID received from the operation unit is successfully authenticated, and the lock device is unlocked in conjunction with the setting of the security mode that determines the operation of the security device.

  FIG. 13 is an explanatory diagram illustrating a configuration of a lock apparatus according to the second embodiment. As shown in FIG. 13, the lock device 200 according to the present embodiment is connected to a security device 600, and includes a front 1 and a lock mechanism 3 installed at an entrance door, a security mode operation unit 610, and an external power supply. The lock mechanism 3 mainly includes a deadlocking latch bolt 10, a manual operation unit 30, a slider 40, a locking lever 50, a connecting lever 60, a handle unit 70, and the like. A latch hold 80, a trigger head 85, and a solenoid 90 are mainly provided. Here, the front 1, the deadlocking latch bolt 10, the manual operation unit 30, the slider 40, the locking lever 50, the connecting lever 60, the handle 70, the latch hold 80, the trigger head 85, and the solenoid. Since 90 is the same as the lock device according to the first embodiment, the description thereof is omitted.

  The security device 600 monitors (guards) the monitoring area where the doorway is installed, and is a report destination when an abnormality occurs in the monitoring area when the security mode is set to the security state. It reports the abnormality detection information that an abnormality has been detected to the monitoring center. The security device 600 does not report the abnormality detection information to the monitoring center when an abnormality occurs in the monitoring area when the security mode is set to the security release state. 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 200 is connected to the security device by wire, but may be configured to be connected by wireless communication.

  Here, the security mode refers to the necessity of reporting to the monitoring center when various sensors installed in the monitoring area detect the opening of windows and doors or the presence of people, or notification to the monitoring area. This is a mode for determining the operation of the security device 600 at the time of detection operation of various sensors, such as whether or not it is necessary. The security mode includes a plurality of modes depending on necessity of notification, notification destination, necessity of notification to the monitoring area, and the like. As a typical security mode, when various sensors perform detection operations, for example, when monitoring area abnormalities are detected and a person entering a monitoring area is detected, a monitoring center that is a predetermined notification destination There is a security state in which the abnormality detection information is reported to the monitoring center and a security release state in which the abnormality detection information is not reported to the monitoring center when various sensors perform detection operations, and the security device 600 has a security mode operation unit 610 to be described later. The security mode is set in accordance with the input operation received from.

  The security mode operation unit 610 is installed outside the monitoring area in the vicinity of the entrance door, and accepts an input of a unique user ID to a user such as a security guard, similarly to the operation unit in the first embodiment. Furthermore, the security mode operation unit 610 accepts the setting of the security state or the security release state as the security mode set in the security device 600. The security mode operation unit 610 is provided with a control unit 611.

  The control unit 611 controls energization to the solenoid 90. That is, the control unit 611 performs user authentication by checking whether or not the user ID received by the security mode operation unit 610 is a user ID predetermined in a storage unit (not shown). When the user authentication succeeds and the setting of the security release state is accepted by the security mode operation unit 610, the solenoid 90 is energized, and the solenoid 90 is de-energized after a predetermined time has elapsed. Further, the control unit 611 is connected to a general-purpose power source, and normally supplies power supplied from the general-purpose power source to a monitoring area or the like to the security mode operation unit 610, the solenoid 90, etc. When the power cannot be supplied due to a power failure or the like, the control unit 611 supplies the power supplied from the external power supply unit 620 to the security mode operation unit 610 and uses the user ID received from the security mode operation unit 610. When the person authentication is successful and the setting of the security release state is accepted, the power supplied from the external power feeding unit 620 is supplied to the solenoid 90 and energized.

  The external power supply unit 620 can supply power independently to the control unit 611 in the security mode operation unit 610, and corresponds to, for example, a battery. When the control unit 611 is not supplied with power from a general-purpose power source due to a power failure or the like, the control unit 611 is supplied with power from the external power feeding unit 620. It is possible to control energization.

  Next, the difference between the operation of the lock apparatus 200 having the above-described configuration and the first embodiment will be described. About the mechanical locking / unlocking in the lock apparatus 200, since it is the same as that of 1st Embodiment, description is abbreviate | omitted.

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 security mode operation unit 610 installed near the doorway. Then, input the setting of the security release state. When the security mode operation unit 610 receives the input of the user ID and the setting of the security release state, the control unit 611 verifies whether or not the received user ID is a user ID predetermined in the storage unit or the like. Thus, user authentication is performed, and when the user authentication is successful, the solenoid 90 is energized. Since the operation of the lock apparatus 200 after the solenoid 90 is energized is the same as that of the first embodiment, the description thereof is omitted.

  As described above, the lock device 200 according to the second embodiment is configured so that the security mode operation unit 610 can be used even if a user such as a security guard does not receive a key for unlocking the entrance door of the monitoring area in advance. The door can be locked and unlocked simply by entering the user ID, reducing the burden of securing and managing the entrance door key storage, as well as a cylinder or thumb turn to insert the door door key. No maintenance work such as machining is required.
