Description

  The present invention relates to a lock forgetting prevention system, and more particularly, to a lock forgetting prevention system that is used for a sliding door or a sliding window (a slidable door window) and issues a warning to prevent forgetting to lock.

  Conventionally, the sliding door and the sliding window provided in the building detect the opening of the window and send a signal to the buser (alarm generating device) to generate an alarm sound, a magnet switch type, Various sensors (detection means) such as an infrared type and a vibration detection type are used.

  This sensor operates electrically in the same way as a buzzer, and during the day when door windows are opened and closed complicatedly for people to enter and exit, ventilation, etc. On the other hand, in the evening or at night, both are turned on for crime prevention (security), and the door window is locked to completely prevent a suspicious person from entering the building.

  However, in such a door window, when the door window closes the opening of the window, even if the sensor power is turned on, no alarm sound is emitted from the buzzer. There is no means for confirming the presence or absence of locking other than confirmation, which may cause forgetting to lock, and there is a concern that the building may be temporarily invaded by a suspicious person and cause damage such as theft.

  In view of the above-described problems, an object of the present invention is to provide a lock forgetting prevention system that can reliably prevent forgetting to lock and obtain a high crime prevention effect.

  The lock forgetting prevention system according to the present invention is a lock forgetting prevention system used for a door window that slidably opens and closes an opening. The lock forgetting prevention system detects that the door window has been opened and generates an alarm at the time of detection. Detecting means for transmitting a signal to the alarm generating device and biasing means attached to at least one of the door window or the opening forming member forming the opening and biasing the door window in the opening direction It is characterized by comprising.

  According to the lock forgetting prevention system, as long as the door window is not locked, the door window is automatically opened by the urging means, the fact of the opening is detected by the detecting means, and an alarm is generated from the alarm sound generator. Since it is emitted, it is possible to reliably prevent forgetting to lock.

  The detecting means is electrically operated, and the urging means includes a solenoid electromagnet attached to one of the door window or the opening forming member and a permanent magnet attached to the other, the solenoid electromagnet Is configured to be turned on / off in conjunction with the detecting means, and preferably generates a magnetic pole so as to repel the permanent magnet when the power is turned on.

  According to the above preferred configuration, the detection means and the solenoid magnet are turned on / off in conjunction with the drive means. For example, during the day when it is not necessary to lock, the detection means and the solenoid electromagnet are turned off. In the evening or at night when the door is opened, the detection means and the solenoid electromagnet are turned on, and the door window is opened when the door is not locked. It can be automatically opened and a warning can be issued. Thereby, the lock forgetting prevention system can be operated only when necessary.

  As described above, according to the lock forgetting prevention system according to the present invention, forgetting to lock can be reliably prevented and a high crime prevention effect can be obtained.

  Hereinafter, an embodiment of a lock forgetting prevention system according to the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a state in which the lock forgetting prevention system of the present embodiment is used for a sliding window (door window) 2 that opens and closes a window opening 1 slidably. The lock forgetting prevention system includes a sensor (detecting means) 3 for detecting that the pulling window 2 is opened, and a spring attached to the pulling window 2 and biasing the pulling window 2 in a direction to open the opening 1. (Biasing means) 5. The sensor 3 is configured to transmit a signal to a buzzer (alarm generator) (not shown) to generate an alarm sound when the opening of the sliding window 2 is detected.

  In the sliding window 2 shown in FIG. 1, a pair of left and right sliding windows 2a and 2b is a so-called sliding window that slides alternately to open and close the opening 1 of the window. Then, a crescent lock (key portion) that locks by engaging a pair of metal fittings (crescent main body 6a, crescent receptacle 6b) fixed to each of the sliding windows 2a, 2b so as to be positioned at the center of the opening 1 6 is provided. Moreover, the window glass 7 and 7 is engage | inserted by each sliding window 2a, 2b.

  The sensor 3 is a so-called inductive proximity switch, and a coil coupled to a high-frequency oscillation circuit is used as a detection element. When the detection body approaches, an induced current flows due to electromagnetic induction, and a change in inductance of the coil causes an oscillation circuit. The fact that the constant changes and the fact that the sensor 3 approaches and separates from the detection body is detected through changes in the oscillation amplitude and the oscillation frequency. When the sensor 3 is separated from the detection body, a signal is transmitted to the buzzer (alarm generating device) to generate an alarm sound, and when the sensor 3 approaches the detection body, the signal is not transmitted. .

  In the lock forgetting prevention system of the present embodiment, the sensor 3 is mounted on the upper left corner of the left sliding window 2a (the upper end of the left vertical fence), and the detection body 8 has a window frame (opening formation). Member) In order to approach the sensor 3 when the pulling window 2a closes the opening 1 at the upper left corner of the member 4 (when the vertical gutter on the left side of the pulling window 2a contacts the left frame part of the window frame 4). It is installed.

  In addition, the lock forgetting prevention system of the present embodiment includes a spring (biasing member) 5 held by a spring holding member 9 fixed by a bolt at the lower left corner of the sliding window 2a. When the opening 1 of the window is closed by the pulling window 2a, the pulling window 2a is always in a direction in which the opening 1 is opened by coming into contact with the protrusion 10 fixed to the lower left corner of the window frame 4 with a bolt. The pulling window 2a is slightly opened at the time of unlocking (unlocking the left end of the opening 1).

  The lock forgetting prevention system of the present embodiment operates as follows. That is, when the sliding window 2a is closed while the power source of the sensor 3 is turned on by a driving unit (not shown), it is detected that the sensor 3 has approached the detection body 8, and the sensor 3 detects that the buzzer A signal for generating an alarm sound is not transmitted. On the other hand, when the sliding window 2a is opened, the fact that the sensor 3 is separated from the detection body 8 is detected, a signal is transmitted from the sensor 3 to the buzzer, and an alarm sound is emitted from the buzzer in response to the signal.

  Further, since the pulling window 2a is always biased by the spring 5, the elastic force of the spring 5 is obtained when the pulling window 2a is slidable by unlocking (removing the crescent lock). As a result, the sliding window 2a is slightly opened, and at this time, the sensor 3 is separated from the detection body 8 and a warning sound is emitted from the buzzer.

  Further, even when the unlocking is performed and only the right pulling window 2b is opened, the pulling window 2a slightly opens the window opening 1 by the action of the spring 5, so that an alarm sound is emitted from the buzzer.

  As described above, according to the lock forgetting prevention system of the present embodiment, each of the sliding windows 2a and 2b is automatically opened by the action of the spring 5 unless the sliding windows 2a and 2b are locked. Since the opening fact is detected by the sensor 3 and an alarm sound is emitted from the buzzer, the fact that the sliding windows 2a and 2b are not locked can be surely known. As a result, it is possible to reliably prevent forgetting to lock and to obtain a high crime prevention effect.

  In the lock forgetting prevention system of this embodiment, even if the sensor 3 is provided only in one sliding window 2a of the sliding window having a pair of left and right sliding windows 2a and 2b, the spring 5 opens the sliding window 2a in the opening direction. As long as the sliding window 2a is slightly opened unless it is locked, the fact that one of the sliding windows 2a, 2b is unlocked by breaking the window glass 7 and opening it illegally is the fact. Is reliably detected by the sensor 3. Therefore, a high locking forgetting prevention effect can be obtained without providing the sensor 3 on both sides of the sliding windows 2a and 2b. Therefore, the number of parts used can be reduced, and the part cost can be reduced at a low cost.

  In addition, since the lock-forgetting prevention system according to the present embodiment includes the sensor 3 and the spring 5 as main components, it can be easily installed on the wall of the existing sliding window 2 or the window frame 4 (or wall surface).

  The lock forgetting prevention system of the present invention is not limited to the above-described embodiment, and various embodiments can be implemented within the scope of the technical idea of the present invention.

  For example, in the lock forgetting prevention system of the above embodiment, the spring 5 is provided on the pulling window 2 side. However, the pulling window 2 is urged in the opening direction, and a warning sound is emitted from the sensor 3 to the buzzer when the pulling window 2 is unlocked. As long as the signal to be transmitted is transmitted, it can be provided on the window frame 4 (or wall surface) side.

  Further, although the spring 5 is used as the urging member, the urging means is attached to the solenoid electromagnet 5a attached to one of the sliding window 2 (2a) or the window frame 4 and the other as shown in FIG. It is also possible to include the permanent magnet 5b. In this case, the solenoid electromagnet 5a is configured to be turned on / off in conjunction with the sensor (detection means) 3 by a driving means (not shown), and the magnetic pole is repelled from the permanent magnet 5b when the power is turned on. To occur.

  According to this, since the solenoid electromagnet 5a is turned on / off in conjunction with the sensor 3, the power of the sensor 3 and the solenoid electromagnet 5a is turned off and the sliding window 2 is turned off during the day when it is not necessary to lock the solenoid electromagnet 5a. In the evening or at night, when the door is opened, the sensor 3 and the solenoid electromagnet 5a are turned on, and the sliding window 2 is automatically opened when the door is not locked. Can be set to a state where an alarm is issued. Thereby, the lock forgetting prevention system can be operated only when necessary.

  Furthermore, in the above embodiment, an alarm sound is emitted from the alarm generation device (buzzer) in order to recognize the unlocked state, but instead, a red light is emitted from the alarm generation device so as to stand out well. Furthermore, instead of providing an alarm generating device, a signal is transmitted from the sensor 3 to a centralized monitoring device installed in the management room, and the sliding window 2 is opened by the centralized monitoring device based on the signal. The situation may be monitored.

It is a use condition figure of the lock forgetting prevention system concerning one embodiment of the present invention. It is an enlarged view of the urging member concerning another embodiment of the present invention.
