Description

  The present invention relates to a locking device and a locking / unlocking method for locking / unlocking an entrance door, and more particularly to a locking device and a locking / unlocking method that are locked when an illegal act is performed.

  In recent years, for the purpose of preventing unauthorized intrusion, an attempt has been made to improve crime prevention by implementing so-called one-door-to-lock in which two lock devices, a main lock and an auxiliary lock, are installed in one doorway. In other words, the effect that can be expected by carrying out one-door-to-lock is that by installing a main lock and an auxiliary lock, it is possible to reduce the labor and time required for work in various non-destructive illegal unlocking means (picking, thumb turn, etc.). Unauthorized unlocking is difficult by making it about double, making unauthorized opening means (breaking, breaking the lock, etc.) illegally involving the entrance door and lock device, and installing an auxiliary lock. In addition to the above, it is possible to make an intruder feel that the resident's security consciousness is high, thereby losing the criminal intention and preventing the crime from being committed.

  Therefore, conventionally, two lock devices, a main lock and an auxiliary lock, are generally used for one doorway. For example, when locking from the outdoor side, if one cylinder lock is locked, the other cylinder lock can be automatically locked, but when unlocking, a locking device is disclosed in which each is unlocked separately ( For example, see Patent Document 1). Also, when one of the two electric locks is locked, the other electric lock is locked in conjunction with this, but when one of the electric locks is unlocked, the other electric lock is locked. Discloses an electric lock device that maintains a locked state without interlocking with this operation (see, for example, Patent Document 2).

  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 embodiments, the main lock used for the purpose of restricting the entrance (entrance) of non-related persons who do not possess the key to the entrance door, and unauthorized intruders who make it difficult to unlock and open This is an example in which an auxiliary lock used for the purpose of deterring / preventing unauthorized entry of a door is installed, and the lock device of the present invention is applied to the auxiliary lock.

(Embodiment 1)
The auxiliary lock, which is the lock device according to the present embodiment, is normally unlocked, and is a lock device that does not require a lock / unlock operation when entering or leaving a legitimate user. When an action is detected, the state is shifted from the unlocked state to the locked state to prevent intrusion by an unauthorized intruder.

  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, etc.) are overwhelmingly large compared to unauthorized opening means (peg opening, unlocking, etc.) involving destruction of doors and locks. Therefore, for the purpose of mainly preventing unauthorized unlocking means, it is unlocked when a legitimate user enters the building, and only when unauthorized unlocking is attempted, the unlocked state is changed to the unlocked state. The auxiliary lock which is a lock device will be described below.

  FIG. 1 and FIG. 2 are views showing the entire entrance door in which the auxiliary lock and the main lock according to the first embodiment are installed. In FIGS. 1 and 2, the left side view is a rear view of the entrance door 1 as viewed from the inside of the room partitioned by the entrance door 1, the center view is a side view of the entrance door 1, and the right side view is the entrance / exit. It is the front view which looked at the door 1 from the exterior of a room. As shown in FIGS. 1 and 2, the door 1 is provided with an auxiliary lock 100 on the upper side and a main lock 600 on the lower side. In the main lock 600, the user inserts a key into the cylinder 3 and rotates it, or picks the thumb turn 6 and manually moves the dead bolt 5 to move the door 1 in the locked or unlocked state. To.

  Here, the locked state is a state where the door 1 cannot be opened even if the lever handle 4 provided on the door 1 is operated. For example, the locked state by the main lock 600 means that the door 1 is opened by holding the dead bolt 5 in a hole (not shown) provided in the wall surface of the door facing the main lock 600. It cannot be opened (see FIGS. 1 and 2). The unlocked state is a state where the door 1 can be opened by operating the lever handle 4 provided in the door 1. For example, the unlocked state by the main lock 600 is a state in which the doorway door 1 can be opened by removing the dead bolt 5 from the hole (not shown) and holding it inside the doorway door 1.

  Further, the auxiliary lock 100 is embedded in the doorway door 1 and, like the main lock 600, moves the doorway door 1 into a locked state or an unlocked state by moving the dead bolt 10. In addition, the auxiliary lock 100 is connected to a fraud detection unit 110 that detects fraudulent acts by an unauthorized intruder P. Here, the unlocked state by the auxiliary lock 100 means that the dead bolt 10 is removed from a hole (not shown) provided in the entrance / exit wall surface facing the auxiliary lock 100 and held inside the entrance door 1. In this state, the door 1 can be opened (see FIG. 1). Further, the locked state by the auxiliary lock 100 is a state in which the door 1 cannot be opened by holding the dead bolt 10 in the above-described hole (not shown) (see FIG. 2).

  That is, in FIG. 1, the main lock 600 is in the locked state and the auxiliary lock 100 is in the unlocked state, and in FIG. 2, both the main lock 600 and the auxiliary lock 100 are in the locked state. In the present embodiment, since the main lock 600 and the auxiliary lock 100 are installed on the door 1, the door 1 can be opened when both the main lock 600 and the auxiliary lock 100 are unlocked. However, in other words, the main lock 600 is unlocked and the auxiliary lock 100 is locked, the main lock 600 is locked and the auxiliary lock 100 is unlocked, and both the main lock 600 and the auxiliary lock 100 are locked. At this time, the door 1 cannot be opened.

  Next, the details of the configuration of the auxiliary lock 100 will be described with reference to FIGS. FIG. 3 is a diagram showing the unlocked auxiliary lock in the first embodiment. FIG. 4 is a diagram showing the auxiliary lock in the locked state in the first embodiment. As shown in FIGS. 3 and 4, the auxiliary lock 100 of the present embodiment includes a front 101 and a lock mechanism 102, and the lock mechanism 102 includes a motor 40, a gear 43, a rail 30, and a center. The gear 20, the rail 13, the dead bolt 10, the micro switch 50, the fraud detection unit 110, and the control unit 120 are mainly provided.

  The front 101 is a plate-shaped metal plate that has an opening (not shown) through which the dead bolt 10 enters and exits and covers the side surface of the lock mechanism 102. In addition, screw holes (not shown) for fixing the lock mechanism 102 to the entrance door 1 are provided in the upper part and the lower part of the front 101. When the auxiliary lock 100 is installed in the entrance door 1, the lock mechanism 102 is embedded in the entrance door 1, and the front 101 can be seen on the side surface of the entrance door 1.

  The motor 40 converts electrical energy into mechanical energy, and a shaft portion 42 is connected to the lower portion of the motor body 41. The motor 40 rotates the shaft portion 42 forward and backward when energized. That is, the motor 40 rotates the shaft portion 42 in the direction of arrow R1 (see FIG. 3) (forward rotation) or rotates in the direction of arrow R3 (see FIG. 4) (reverse rotation).

  The gear 43 is provided at the end opposite to the motor 40 side of the shaft portion 42 connected to the motor 40, and rotates in the direction of the arrow R1 and the arrow R3 in conjunction with the rotation of the shaft portion 42. is there.

  The rail 30 is a rod-like member having irregularities on the side surfaces and teeth 30 a on the lower side, and is arranged so that the irregularities mesh with the gear 43. When the gear 43 rotates in the arrow R1 direction, the rail 30 moves in the arrow A direction (see FIG. 3) along with the rotation. Further, when the gear 43 rotates in the arrow R3 direction, the rail 30 moves in the arrow C direction (see FIG. 4) along with the rotation.

  The central gear 20 is a gear provided with teeth 20 a and is arranged so as to mesh with the teeth 30 a of the rail 30 and the teeth 13 a of the rail 13. When the rail 30 moves in the direction of arrow A, the central gear 20 rotates in the direction of arrow R2 (see FIG. 3) along with the movement. Further, when the rail 30 moves in the direction of arrow C, the central gear 20 rotates in the direction of arrow R4 (see FIG. 4) along with the movement.

  The rail 13 is a rod-like member provided with teeth 13a on the upper portion, and is fixed to the shaft portion 11 of the dead bolt 10 while meshing with the teeth 20a of the central gear 20. Then, when the central gear 20 rotates in the arrow R2 direction, the rail 13 moves in the arrow B direction (see FIG. 3) along with the rotation, and moves the dead bolt 10 in the arrow B direction. Further, when the central gear 20 rotates in the direction of arrow R4, the rail 13 moves in the direction of arrow D (see FIG. 4) along with the rotation, and moves the dead bolt 10 in the direction of arrow D.

  The dead bolt 10 includes a shaft portion 11, a tip portion 12, and a protrusion 14, and moves in the direction of arrow B or arrow D along with the movement of the rail 13 installed on the shaft portion 11. Thus, the door 1 is brought into a locked state or an unlocked state. That is, the dead bolt 10 is such that the distal end portion 12 is detachably moved with respect to a hole portion (not shown) provided in the wall surface of the doorway that houses the doorway 1 and moves in the direction of arrow B. By holding the state where the distal end portion 12 is inserted into the hole portion, the entrance door 1 is locked, moved in the direction of arrow D, and the distal end portion 12 is removed from the hole portion and held inside the entrance door 1. The door 1 is brought into an unlocked state. The protrusion 14 is provided at the lower right portion of the shaft portion 11 so as to contact the microswitch 50.

  The micro switch 50 is a switch that opens and closes a contact by detecting the presence and position of an object, and is provided inside the frame portion of the lock mechanism 102. When the dead bolt 10 is unlocked, the contact 51 is It is installed in contact with the protrusion 14. Then, when the dead bolt 10 is moved in the arrow B direction to be in the locked state, the microswitch 50 is in the “open” state when the contact 51 is opened, and the dead bolt 10 is moved in the arrow D direction to be in the unlocked state. Then, the contact point 51 pressed by the projecting portion 14 is closed to be in a “closed” state.

  The fraud detector 110 is installed inside or inside the door 1 and detects fraud when the fraudulent act such as fraud is performed on the main lock. A sensor for detecting, a sensor for separating and detecting sound waves, and the like. For example, the fraud detection unit 110 may be a fraud detection unit when an unauthorized intruder performs an unlocking operation such as picking for unlocking from the main lock cylinder 3 (see FIG. 1) using a special metal tool. 110 detects vibrations to the main lock and sound waves emitted from the main lock as fraud, and sends a signal to that effect to the control unit 120. The fraud detection unit 110 is configured to detect fraud by installing a “picking alarm” that is generally commercially available and senses the act of attempting to unlock illegally by inserting a picking tool into the cylinder. It is good.

  The control unit 120 controls the movement of the dead bolt 10 via the motor 40, and further includes a locking / unlocking control unit 121 and a locking / unlocking state acquisition unit 122.

  The locking / unlocking control unit 121 normally sets the dead bolt 10 to the unlocking state by setting the deadbolt 10 to the state shown in FIG. 3, and when receiving a signal from the fraud detection unit 110 that fraud has been detected, Then, the shaft 42 is driven to rotate in the forward direction, and the dead bolt 10 is shifted from the unlocked state to the locked state.

  Specifically, the locking / unlocking control unit 121 drives the motor 40 to rotate the shaft 42 in the direction of arrow R1 (forward rotation). Then, along with the rotation, the gear 43 also rotates in the direction of arrow R1, the rail 30 moves in the direction of arrow A in conjunction with the rotation of the gear 43, and the central gear 20 rotates in the direction of arrow R2. Then, the rail 13 moves in the direction of the arrow B in conjunction with the rotation of the central gear 20, and the dead bolt 10 also moves in the direction of the arrow B, so that the tip 12 is inserted into the hole of the entrance and exit. It will shift to the locked state.

  Further, the locking / unlocking control unit 121 drives the motor 40 so as to reversely rotate the shaft portion 42 when a predetermined time is measured by the locking / unlocking state acquisition unit 122 described later from the time when the dead bolt 10 is locked. Then, the dead bolt 10 is shifted from the locked state to the unlocked state.

  Specifically, the locking / unlocking control unit 121 drives the motor 40 to rotate (reversely rotate) the shaft portion 42 in the direction of the arrow R3. Then, along with the rotation, the gear 43 also rotates in the direction of the arrow R3, the rail 30 moves in the direction of the arrow C in conjunction with the rotation of the gear 43, and the central gear 20 rotates in the direction of the arrow R4. Then, the rail 13 moves in the direction of the arrow D in conjunction with the rotation of the central gear 20, and the dead bolt 10 also moves in the direction of the arrow D, so that the tip 12 is removed from the hole of the entrance and exit, and the entrance door 1 Will be shifted to the unlocked state.

  The locked / unlocked state acquisition unit 122 starts from the time when the door 1 is locked, that is, when the dead bolt 10 moves in the direction of the arrow B, so that the contact 51 of the microswitch 50 is in the “open” state. A timer function for measuring a predetermined time (for example, 3 minutes) is provided. Further, the unlocking state acquiring unit 122 determines that the dead bolt 10 is in the locked state when the contact 51 of the micro switch 50 is in the “open” state, and determines that the contact 51 of the micro switch 50 is in the “closed” state. It is determined that the dead bolt 10 is unlocked.

  Next, with reference to FIGS. 3-5, the locking / unlocking operation | movement of the auxiliary | assistant lock of this Embodiment is demonstrated. FIG. 5 is a flowchart showing the flow of the locking / unlocking operation of the auxiliary lock according to the first embodiment.

  First, the locking / unlocking control unit 121 determines whether or not the fraud detection unit 110 has detected an unauthorized act due to an unauthorized intruder performing an unauthorized unlocking operation such as picking the main lock (step S10). . When fraud is not detected by the fraud detector 110 (step S10: No), the process returns to step S10.

  On the other hand, when the fraud detection is detected by the fraud detection unit 110 (step S10: Yes), the unlocking / unlocking state acquisition unit 122 determines whether the door 1 is unlocked, that is, as illustrated in FIG. Whether or not the dead bolt 10 is held inside the door 1 is determined based on the open / close state of the microswitch 50 (step S11). When the door 1 is unlocked (step S11: Yes), the locking / unlocking control unit 121 drives the motor 40 to rotate the shaft portion 42 in the forward direction, thereby removing the dead bolt 10 from the door hole. The door 1 is inserted into the door and the door 1 is shifted to the locked state (step S12).

  Next, the locking / unlocking state acquisition unit 122 performs a predetermined time measurement from the time when the doorway door 1 is locked. And the locking / unlocking control part 121 judges whether predetermined time passed by the measurement of the locking / unlocking state acquisition part 122 (step S13). If the predetermined time has not elapsed (step S13: No), the process returns to step S13 and waits until the predetermined time elapses.

  On the other hand, when predetermined time passes (step S13: Yes), the locking / unlocking control part 121 removes the dead bolt 10 from the hole of an entrance, and transfers the entrance door 1 to an unlocking state (step S14). In step S11, when the door 1 is locked (step S11: No), the locking / unlocking control unit 121 drives the motor 40 when a predetermined time has elapsed from the time when it is determined to be locked. Then, by rotating the shaft portion 42 in the reverse direction, the dead bolt 10 is removed from the hole portion of the doorway, and the doorway door 1 is shifted to the unlocked state (step S14).

  As described above, the auxiliary lock 100 according to the first embodiment is normally unlocked, and when an illegal act such as unauthorized unlocking is detected, the dead bolt 10 is changed from the unlocked state to the locked state. Therefore, when an authorized user enters or exits, the door 1 is locked only with the main lock, so that the door 1 can be locked and unlocked by a single locking and unlocking operation. Convenience can be improved without forcing operation. In addition, when an illegal act is detected, the door 1 is locked by the two lock devices of the main lock and the auxiliary lock 100. Therefore, it is difficult for an unauthorized intruder to perform the unlocking operation, thereby improving crime prevention. .

  In addition, since the auxiliary lock 100 according to the first embodiment shifts from the locked state to the unlocked state after a predetermined time has passed since the locked state, the authorized user enters and exits after the unauthorized intruder leaves. In the case of building, the entrance door 1 can be locked / unlocked by a single locking / unlocking operation as described above without performing the process for returning to the original state.

(Modification of Embodiment 1)
The auxiliary lock according to the first embodiment is configured to shift from the unlocked state to the locked state when an illegal act is detected, and is installed inside the entrance door. Therefore, in Embodiment 1, it is not known from the outside that the auxiliary lock is provided. Therefore, in the present embodiment, an imitation cylinder (dummy cylinder) that reminds an unauthorized third party that the auxiliary lock of the first embodiment is installed is installed in the entrance door 1.

  FIG. 6 is a diagram illustrating the entire entrance door provided with the auxiliary lock and the main lock according to the modification of the first embodiment. FIG. 6 is a front view of the door 1 as viewed from the outside of the room, and a dummy cylinder 200 is provided outside the door 1 corresponding to the position where the auxiliary lock 100 is installed inside. FIG. 7 is a diagram showing an example of a dummy cylinder that has been drawn reminiscent of the fact that an auxiliary lock that performs an electrical locking / unlocking operation is installed. Note that the configurations, functions, and locking / unlocking operations of the auxiliary lock 100 and the main lock 600 are the same as those in the first embodiment, and thus description thereof is omitted.

  The dummy cylinder 200 is reminiscent of the fact that a second lock device is installed in the door 1 and does not have an actual locking / unlocking function. That is, the dummy cylinder 200 is reminiscent of not only the main lock but also the auxiliary lock. Further, as shown in FIG. 7, the dummy cylinder 200 is provided with a drawing 201 in which a hand holding an IC (Integrated Circuit) tag or the like is drawn, and the IC tag or the like is brought close to the dummy cylinder 200 without contact. You may comprise so that it may be associated with performing electrical locking / unlocking operation.

  As described above, in the modification of the first embodiment, by providing the dummy cylinder 200 with the drawing 201 on the entrance door 1, an unauthorized intruder who wants to enter from the outside can be provided with a second on the entrance door 1. It can be visually reminded that an auxiliary lock, which is a lock device, is installed. Therefore, the installation of an auxiliary lock reminiscent of an electric lock, which is the second lock device, makes it difficult for unauthorized unlocking and makes the intruder feel that the occupant has a high security consciousness, resulting in a loss of criminal intention. It can be encouraged not to reach sexual offenses.

  Further, the dummy cylinder 200 has the same external appearance as that of a general cylinder, and the above-described fraud detection unit 110 is incorporated therein. The fraud detection unit 110 further prevents the dummy cylinder 200 from being fraudulent. You may comprise so that a vibration and the sound wave emitted from the dummy cylinder 200 may be detected as an unauthorized act. As a result, even when an unauthorized intruder attempts an illegal act such as picking on the dummy cylinder 200, the fraud detector 110 detects an illegal act on the dummy cylinder 200, and the locking / unlocking control unit 121 unlocks the dead bolt 10. The state can be shifted to the locked state.

(Embodiment 2)
The auxiliary lock of the first embodiment performs the locking / unlocking operation by the locking / unlocking control unit and the locking / unlocking state acquisition unit provided in the control unit when an illegal act is detected. In the auxiliary lock according to the present embodiment, when an illegal act is detected, an alarm or the like is transmitted to the monitoring center, and a locking / unlocking instruction is received from the monitoring center to perform locking / unlocking.

  FIG. 8 is a diagram illustrating an entire entrance door provided with the auxiliary lock and the main lock according to the second embodiment. In FIG. 8, the left side view is a rear view of the entrance door 1 viewed from the inside of the room partitioned by the entrance door 1, the center view is a side view of the entrance door 1, and the right side view is the entrance door 1. It is the front view which looked at from the exterior of a room. As shown in FIG. 8, the door 1 is provided with an auxiliary lock 300 on the upper side and a main lock 600 on the lower side. As in the first embodiment, the main lock 600 moves the deadbolt 5 by inserting a key into the cylinder 3 and rotating it by the user, or by picking the thumb turn 6 and performing manual operation.
