Description

  The present invention relates to a locking device used for buildings, cars, and the like.

  In recent years, for example, in a car, a system that can be unlocked without directly inserting a key into a keyhole has been put into practical use and gaining popularity. That is, such a thing is given a key to the owner of the car, and when the user who owns the key touches the outdoor knob on the door of the car, communication between the key and the outdoor antenna is performed at that time. In this communication, when the identification information owned by the key matches the specific information managed by the vehicle controller, the door is unlocked.

In addition, as such a conventional example, there exists what is shown in patent document 1. FIG.
JP-A-60-159259

  As described above, a so-called system for unlocking a lock without inserting a key into a keyhole is very easy to use, and in recent years, it has been widely used in vehicles. For example, when an attempt is made to install such a system in a house, when the owner holding the key similarly touches the touch sensor provided on the knob on the outdoor side, the key and the outdoor side are in that state. When the communication with the antenna is performed, and the identification information held by the key matches the specific information held by the controller, as in the case of the vehicle, the lock is unlocked.

  The owner thus enters the room and then tries to operate the knob provided on the indoor side of the door again when going out of the room. At this moment, at the moment when the hand touches the door, the touch sensor compares the key identification information with the controller specific information again, and if the information matches, the lock is unlocked, thereby allowing the owner to You can go out to.

  However, in everyday life, for example, when trying to take indoor trash to a collection place right in front of the house, even in that case, it may not be possible to take it out without holding the key. This is very annoying in daily life, and every time you go out for a moment, you will find the key and then go out, which is very inconvenient.

  Then, this invention aims at improving usability in a locking device.

  In order to achieve this object, the present invention has a configuration in which a forced unlocking switch is provided on the indoor side, and the lock is forcibly unlocked for a predetermined time by operating the forced unlocking switch.

  That is, if a forced unlocking switch is provided on the indoor side in this way, the lock is unlocked for a predetermined time by the operation, so that the key holder or the like can go out to work outside the room for an instant. Is possible. Therefore, it becomes very convenient.

  As described above, the present invention provides a forced unlocking switch on the indoor side in a locking device configured to unlock the door by communication with a room and an external antenna using a key. The user can go out by operating this forced unlocking switch without having to hold the key when going out from the inside instantly, which is very convenient.

  FIG. 1 shows an example in which an embodiment of the present invention is installed in a house. In FIG. 1, reference numeral 1 denotes an outer wall, and a portion surrounded by the outer wall 1 is a room 2. Moreover, the door 3 is provided in one place of the outer wall 1 so that opening is possible. The door 3 is provided with a lock 4 shown in FIG. Knobs 5 and 6 are provided inside and outside the door 3, respectively.

  FIG. 2 shows such a part in more detail. In FIG. 2, 2 indicates the room and 7 indicates the outdoor.

  In addition to the knobs 5 and 6 described above, the door 3 is equipped with the following. That is, the touch sensor 8 is provided on the knob 5 on the indoor 2 side, and the touch sensor 9 is provided on the knob 6 on the outdoor 7 side. Further, an indoor antenna 10 is provided on the knob 5 on the indoor 2 side, and an outdoor antenna 11 is provided on the knob 6.

  Further, a forced unlocking switch 12 and a display 13 showing a forced unlocking time by the forced unlocking switch 12 are provided on the surface of the door 3 on the room 2 side.

  Such components are arranged as shown in FIG. 3 as a circuit diagram. That is, the touch sensors 8 and 9, the indoor antenna 10, the outdoor antenna 11, the forced unlocking switch 12, and the display 13 are connected to the controller 14. Further, an alarm device 15 is connected to the controller 14.

  In FIG. 3, reference numeral 16 denotes a business card size portable key. The portable key 16 includes a controller 17 and an antenna 18.

  In FIG. 1, reference numeral 19 denotes a door switch for detecting the open / closed state of the door 3.

  Next, the operation of the above configuration will be described.

  First, FIG. 4 shows a main control flow. As shown in this flow, first, when the controller 14 is started, the system is initialized, and then whether or not the outdoor touch sensor 9 is in contact and the indoor touch sensor 8 is in contact. Whether or not the forced unlocking switch 12 has been operated is constantly monitored.

  In this state, when the owner of the portable key 16 returns to the house with the door 3 closed in FIG. 1 and touches the outdoor knob 6, the outdoor touch sensor 9 detects the contact. The flow in this case is shown in FIG. That is, when contact is detected by the outdoor touch sensor 9, the controller 14 attempts to communicate between the outdoor antenna 11 and the antenna 18 of the portable key 16. As a result, when the identification information held by the portable key 16 matches the specific information held by the controller 14, the lock 4 shown in FIG. 3 is unlocked. Of course, if this information does not match, the lock 4 is not unlocked and the monitoring state shown in FIG. 4 is resumed.

  Here, the holder of the portable key 16 can enter the room 2 side. The entry from the outdoor 7 to the indoor 2 can be determined from the door 3 being “closed state → open state → closed state”, and the open / closed state of the door 3 can be detected by the door switch 19. Thereby, when it is determined that the holder of the portable key 16 has entered the room 2 from the outdoor 7, the lock 4 is locked, and the monitoring state shown in FIG. 4 is resumed.

  The above operation shows the operation performed when the owner from outside returns to the home.

  Next, FIG. 6 shows a flow when the owner of the portable key 16 goes out of the room 2 to the outside 7.

  In this case, when contact is detected by the indoor side touch sensor 8, the controller 14 attempts to communicate between the indoor antenna 10 and the antenna 18 of the portable key 16. As a result, when the identification information held by the portable key 16 matches the specific information held by the controller 14, the lock 4 shown in FIG. 3 is unlocked. Of course, if this information does not match, the lock 4 is not unlocked and the monitoring state shown in FIG. 4 is resumed.

  Here, the holder of the portable key 16 can go out to the outdoor 7 side. The exit from the room 2 to the room 7 can be determined from the door 3 being “closed state → open state → closed state”, and the open / close state of the door 3 can be detected by the door switch 19. Thereby, when it is determined that the holder of the portable key 16 has gone out of the room 2 to the room 7, the lock 4 is locked, and the monitoring state shown in FIG. 4 is restored.

  The above operation shows the operation performed when the owner of the room 2 goes outside the room 7.

  Now, finally, FIG. 7 shows an operation when the owner of the portable key 16 in the room 2 side temporarily goes out to carry out, for example, garbage. In this case, for example, the owner first operates the forced unlocking switch 12 in front of the door 3. When this operation is performed, the controller 14 immediately forcibly unlocks the lock 4. This unlocking time is determined in advance. For example, if the forced unlocking switch 12 is pressed once, forced unlocking for 1 minute is performed, and if it is pressed twice, forced unlocking is performed for 2 minutes. The unlocking time and the remaining time in the forced unlocking state are displayed on the display 13. Thus, the user, for example, carries out the trash from the door 3 portion forcibly unlocked, and returns in that state.

  In such a state, the owner, for example, tries to return to the room within 2 minutes at first, but talks with an acquaintance outside the door 3 and may return to the room 2 within the first 2 minutes. In this case, the alarm device 15 issues an alarm when the remaining 30 seconds have been reached.

  When this alarm is issued, if the user touches the knob 6 on the outdoor 7 side, the unlocking can be extended for 1 minute. However, in this case, what is considered in the present embodiment is a state in which the forced unlocking switch 12 is operated to go out of the room, but in this case, the user holds the portable key 16. The situation of the unlocking extension described above differs greatly between the case of being out of the room and the case of not having it.

  For example, when the unlocking time is extended by touching the knob 6 on the outdoor side described above, the state where the portable key 16 is not held is explained, and the portable key 16 is held outside the room. If the alarm is issued from the alarm device 15, even if the user touches the knob 6 on the outdoor side, the user touches the knob 6 on the outdoor side. In the communication with the antenna of the key 16, all of the above-described identification information and the like are verified, and if it is determined that the owner is truly outside the room with the portable key 16, the knob 6 is touched. Even if it is, it will not be extended. This is because the owner is in the state of holding the portable key 16, and there is no need to perform such an extension action. The longer the extension is made, the more anyone can put it in. Therefore, it is not preferable for safety to extend the extension unnecessarily.

  In addition, in the above-described example, when the user goes out of the room with the portable key 16 held, the explanation has been given to stop the extension of the forced unlocking, but the forced unlocking state is canceled immediately. In addition, it can be further preferable in terms of safety measures such as locking.

  In the above-described example, the condition for locking the lock 4 is the time when the door 3 is detected to change from “closed state → open state → closed state” after unlocking. It is also effective for safety measures to lock after a predetermined time has elapsed.

  The detection that the holder of the portable key 16 has moved from the outside to the inside of the room is when the door 3 is detected to change from “closed state → open state → closed state” after unlocking. After detecting this change, the controller 14 tries to communicate with the portable key 16 through the outdoor antenna 11, and the identification information held by the portable key 16 matches the specific information held by the controller 14. You can also In this case, although the user owns the portable key 16 and unlocks it from the room side, the user accidentally goes out of the room without holding the portable key 16 and is locked out of the room side. Can be prevented.

  As described above, the present invention controls the unlocking of the door using the portable key, so that it is very convenient, and further, the extension of the forced unlocking can be stopped. Therefore, safety can be enhanced, which is very useful as a locking device.
