Description

  The present invention relates to an electric lock device that is employed in various doors such as a front door of a house, and is provided with a plurality of locks on one door.

  For example, as an electric lock device used for various doors such as a front door of a house, a one-door two-lock electric lock device having two locks on one door has been conventionally known in order to improve security. It has been. In this type of electric lock device, for example, as shown in Patent Document 1 below, when one lock is changed from unlocking to locking with a cylinder or thumb turn when the door is closed, the other lock follows the lock of the one lock. The lock following operation which locks automatically is performed. As a result, convenience is improved.

  FIG. 3 is a flowchart of the locking follow-up operation of this type of conventional electric lock device. As shown in FIG. 3, in the locking follow-up operation, at the time of locking, it is determined whether or not both locks (main lock and sub lock) are unlocked (ST11), and whether or not the door is closed. Is determined (ST12). Then, when it is determined that both of the two locks are in the unlocked state (ST11-Yes) and it is determined that the door is closed (ST12-Yes), “locking 2” is a start condition for the locking follow-up operation to work. Since the condition of “lock unlocking” is satisfied, it is determined whether one lock (main lock) is locked (ST13), and if it is determined that one lock (main lock) is locked, this one lock (main lock) The other lock (sub-lock) is locked following the locking of the lock (ST14).

Japanese Patent No. 4470943

  As described above, the locking follow-up operation of the conventional electric lock device has a specification that works only when the door is closed. For this reason, if one lock is locked from unlocking with a cylinder or thumb turn before the door is completely closed, i.e. before the door is completely closed, one lock is locked before the door is detected, There was a problem that the condition of “locking 2 door unlocking”, which is the starting condition for the locking follow-up operation, was not satisfied, and the other lock did not follow the locking follow-up operation. The problem that the locking follow-up operation does not work particularly easily occurs in the case of a door having a wide gap between the door and the door frame, so-called dust, because the door closing detection range is narrowed.

  Further, in an electric lock device using a secondary battery as a driving source, a change in the monitor is confirmed at a cycle of about 1 to 2 seconds in order to suppress battery consumption. And in the valley of the cycle, from “opening: 2 lock unlocking” to closing, it becomes “closing door: 2 locking unlocking”, and the upper lock is locked manually, and “door closing: upper locking + lower unlocking” When this occurs, the condition of “closed door 2 lock unlocking” is not satisfied, and there is a problem that the lower lock does not follow the locking operation. The problem that the locking follow-up action does not work is likely to occur when one lock is locked immediately after the door is closed.

  Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide an electric lock device capable of improving the accuracy of the locking follow-up operation.

In order to achieve the above-described object, the electric lock device according to claim 1 is capable of being mechanically locked by manual operation and a main lock capable of being mechanically locked, and can be electrically locked following the lock of the main lock. A plurality of locks including a secondary lock,
Door opening / closing detection means for detecting the opening / closing state of the door;
Detection means for detecting at least locking of the main lock;
All of the plurality of locks are in an unlocked state, the main lock is mechanically locked by manual operation, the door opening / closing detection means detects the closing, and the detection means detects the locking of the main lock. Control means for following the locking of the main lock and electrically controlling the auxiliary lock.

  According to the present invention, even if the main lock is locked by manual operation before the door is completely closed (before the door is detected), the sub lock can be reliably followed and locked after the door is closed.

It is a block diagram showing a schematic structure of an electric lock device concerning the present invention. It is a flowchart figure which shows the operation | movement at the time of locking of the electric lock apparatus which concerns on this invention. It is a flowchart figure which shows the operation | movement at the time of locking of the conventional electric lock apparatus.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the present invention is not limited to this embodiment, and all other forms, examples, operational techniques, etc. that can be implemented by those skilled in the art based on this form are included in the scope of the present invention. .

  The electric lock device according to the present invention is employed for various doors such as a front door of a house, and a plurality of locks are attached to one door. Here, a description will be given by taking, as an example, a configuration of a one-door two-lock in which two locks are attached to one door as an electric lock device.

  As shown in FIG. 1, the electric lock device 1 includes a lock 2, a lock state detection means 3, a manual operation detection means 4, a door opening / closing detection means 5, a control means 6, and a drive means 7.

  The lock 2 is composed of a main lock 11 and a sub-lock 12. The main lock 11 is a lock that is first operated among the two locks 2 at the time of locking and unlocking. Specifically, the main lock 11 includes mechanical locking (and / or unlocking) by manual operation such as rotation operation of the thumb turn on the indoor side and rotation operation of inserting the key into the key hole of the cylinder on the outdoor side, and driving means. 7 is constituted by a lock that can be electrically locked (and / or unlocked) by energization.

  The secondary lock 12 is a lock that can be locked and unlocked following the locking and unlocking of the main lock 11. Specifically, the sub-lock 12 is mechanically locked (and / or unlocked) by manual operation such as inserting and rotating a key into a key hole of an outdoor cylinder, and electrically locked by energization of the driving means 7. It is composed of locks that can be (and / or unlocked).

  The lock state detection means 3 detects whether the current state of each of the main lock 11 and the sub lock 12 is a locked state or an unlocked state as the current state of the lock 2. It consists of state detection means 3a and secondary lock state detection means 3b.

  The main lock state detection means 3a has a conventionally well-known configuration, for example, a micro switch, a Hall IC, a photo interrupter, or the like. The main lock state detection means 3a detects a state in which the dead bolt of the main lock 11 is completely protruded as a locked state, and detects a state in which the dead bolt of the main lock 11 is completely retracted as an unlocked state. A detection signal indicating the locked state or the unlocked state is output to the control means 6 in accordance with the advance / retreat position of the dead bolt of the main lock 11 with respect to the strike hole of the lock 11.

  The secondary lock state detection means 3b is configured in the same manner as the primary lock state detection means 3a, detects a state where the dead bolt of the secondary lock 12 is completely projected as a locked state, and the dead bolt of the secondary lock 12 is completely retracted. The state is detected as an unlocked state, and a detection signal indicating the locked state or the unlocked state is output to the control means 6 according to the advance / retreat position of the dead bolt of the sublock 12 with respect to the strike hole of the sublock 12. ing.

  The manual operation detection means 4 detects the presence or absence of manual operation of the main lock 11 at the time of locking (rotation operation of the thumb turn on the indoor side, rotation operation of inserting the key into the key hole of the cylinder on the outdoor side). When the thumb turn on the indoor side of the lock 11 is rotated or when the key is inserted into the key hole of the cylinder from the outside and rotated, and the state of the main lock state detecting means 3a changes to locked, the control means immediately before 6 detects whether or not a lock control signal is input.

  It should be noted that the manual operation detecting means 4 has the same method for determining whether the main lock 11 is manually operated during unlocking, whether the sub-lock 12 is manually operated during locking, and whether the sub-lock 12 is manually operated during unlocking. Is detected.

  The door opening / closing detection means 5 has a conventionally well-known configuration, and includes, for example, a magnet provided in a strike on the door frame side and a magnetic sensor provided on the door 13 side corresponding to the magnet. The door open / close detection means 5 detects that the magnetic sensor is located in the closed door detection range to which the magnetic field of the magnet is applied by opening / closing the door 13 as a closed door state, and opens when the magnetic sensor is located outside the closed door detection range. The door state is detected, and a detection signal corresponding to the open / close state of the door 13 is output to the control means 6.

  The control means 6 comprehensively controls processing related to locking and unlocking of the lock 2 (the main lock 11 and the sub-lock 12), including the processing of the flowchart shown in FIG. That is, the control means 6 receives the respective detection signals from the lock state detection means 3, the manual operation detection means 4, and the door opening / closing detection means 5, and locks / unlocks the current lock 2 (main lock 11, sub lock 12). The state, the current open / closed state of the door 13, and the presence / absence of manual operation are determined. And according to these discrimination | determination results, a control signal (locking control signal, unlocking control signal) is output to the drive means 7, and locking and unlocking of the lock 2 (the main lock 11, the sublock 12) are controlled. .

  The drive means 7 is constituted by a motor, a solenoid, or the like, and locks or unlocks the lock 2 (the main lock 11 and the sub lock 12) by a control signal from the control means 6. More specifically, when the lock control signal is input from the control means 6, the drive means 7 rotates the cylinder of the main lock 11 to lock the main lock 11, and follows the lock of the main lock 11 to follow the sub lock. 12 is locked. On the other hand, when the unlocking control signal is input from the control unit 6, the driving unit 7 rotationally drives the cylinder of the main lock 11 to unlock the main lock 11, and follows the unlocking of the main lock 11. The secondary lock 12 is unlocked.

  Next, the operation | movement at the time of locking of the electric lock apparatus 1 by the said structure is demonstrated, referring the flowchart figure of FIG.

  First, the control means 6 determines whether or not all the locks 2 (the main lock 11 and the sub lock 12) are in the unlocked state based on the detection signal from the lock state detecting means 3 (ST1). When the control means 6 determines that all the locks 2 (the main lock 11 and the sub lock 12) are in the unlocked state (ST1-Yes), the main lock 11 is locked by manual operation by the manual operation detection means 4. It is determined whether or not it is an electrical lock by energization (ST2).

  When the control means 6 determines that the main lock 11 is locked by manual operation (not electrical lock by energization) (ST2-Yes), the door 13 is detected by a detection signal from the door open / close detection means 5. It is determined whether or not the door is closed (ST3). The control means 6 waits until the door 13 is closed, and if it is determined that the door 13 is closed (ST3-Yes), it outputs a locking control signal to the drive means 7. When the lock control signal is input from the control means 6, the drive means 7 follows the lock of the main lock 11 and locks the sub lock 12 (ST4).

  On the other hand, when the control means 6 determines that the main lock 11 is not locked by manual operation (electrically locked by energization) (ST2-No), the control means 6 proceeds to A of the conventional processing flow of FIG. . 3, the control means 6 determines whether or not the door 13 is closed (ST12), determines that the door 13 is closed (ST12-Yes), and “closes the door 2”. When the start condition for the locking follow-up operation of “lock unlocking” is satisfied, a locking control signal is output to the driving means 7. Then, when the lock control signal is input from the control means 6, the drive means 7 determines whether or not the main lock 11 is locked (ST13), and the main lock 11 is electrically locked by energization of the drive means 7. If it determines with having been carried out, the sublock 12 will be locked following the locking of this main lock 11 (ST14: lock | rock following operation | movement).

  Note that when the lock 2 (the main lock 11 and the sub-lock 12) is unlocked by the electric lock device 1, the control means 6 detects all the locks based on the detection signals from the lock state detection means 3 and the door open / close state detection means 5. 2 (the main lock 11 and the sub-lock 12) are locked and the door is determined to be closed (door 2 lock locked), an unlock control signal is output to the drive means 7. When the unlocking control signal is input from the control unit 6, the driving unit 7 unlocks the main lock 11 and unlocks the sublock following the unlocking of the main lock 11.

  As described above, according to the electric lock device 1 of the present example, in the configuration of the one-door two-lock in which two locks (the main lock 11 and the sub-lock 12) are provided for one door 13, the conventional locking follow-up. The door that has been opened from “2 lock unlocking” in which all locks 2 (the main lock 11 and the sub lock 12) are in the unlocked state by changing the “starting door 2 lock unlocking” which is the starting condition for the operation. Even when the main lock 11 is locked by manual operation before the door 13 is completely closed while closing the door 13 (before the door is detected), the sub-lock 12 follows the lock of the main lock 11 after the door is closed. Locking can be ensured, and the accuracy of the locking follow-up operation can be improved. For this reason, the electric lock device 1 of this example can be adopted also for a wide door in Chile where the door closing detection range is narrow. Further, even when the secondary battery is used as a drive source, the locking follow-up operation can always be performed.

  By the way, in embodiment mentioned above, it demonstrates as what the lock 2 is comprised from the main lock 11 and the sublock 12 which can be mechanically locked by manual operation (unlocking) and electrical locking (unlocking). However, it is not limited to this configuration. That is, the main lock 11 may be configured to be capable of at least mechanical locking and / or unlocking by manual operation. Moreover, the sublock 12 should just be the structure which can follow the main lock 11 and can be electrically locked at least.

  Furthermore, in the above-described embodiment, FIG. 1 shows a configuration in which one sublock 12 that follows the single main lock 11 is provided for one door 13 (one-door two-lock configuration). Although described, the number of sublocks 12 is not limited to one, and a configuration in which two or more sublocks 12 are provided may be used.
