BACKGROUND OF THE INVENTION
The present invention relates to a security system capable of detecting an empty lock of a locking device such as a crescent lock that locks a sliding door.
[0002]
[Prior art]
FIG. 11 is a conventional example 1 in which a window having a sliding door structure composed of four window bodies (frame bodies) 2b fitted with glass 10 is installed on a wall surface of a house or the like. FIGS. 12 (a) and 12 (b) The principal part enlarged view of both ends is shown. Reed switches 60 are respectively attached to the side surface or the upper surface of the sash 2c installed in the Kamoi 50, and magnets 70 are respectively attached to the vertical beam of the window body 2b at both ends and the horizontal beam of the center frame 2b. . The reed switch 60 is driven by magnetism of the magnet 70 when the window body 2b is moved to a position where the window is closed. That is, the reed switch 60 detects the open / closed state of the window.
[0003]
In addition, as a conventional example 2, the main body portion of the locking device used for the sliding door window includes a reed switch and a micro switch that detects the locking and unlocking of the lock device, and a transmission unit that transmits these detection results using a wireless signal. There is also provided a window locking device provided integrally with the part. Also in this case, the open / closed state of the window is detected by the reed switch being driven by a magnet attached to the other party's sliding door or window bar. (For example, refer to Patent Document 1.)

[0005]
[Problems to be solved by the invention]
In the conventional example 1, as shown in FIG. 13, when the window body 2b is closed to the detection distance La10 or less, the reed switch 60 is turned on by the magnetism of the magnet 70, and the window body 2b is opened to the detection distance La10 or more. The reed switch 60 is turned off. That is, the open / closed state of the window can be detected with the detection distance La10 as a boundary. However, the locked state of the locking device cannot be detected, and therefore a so-called empty lock in which the locking device is locked and the window is open cannot be detected.
[0006]
Further, in the above conventional example 2, an empty lock can be detected, but depending on the type of window, the sash and the like are different, and the distance between the reed switch and the magnet is also different. When the window is opened while the locking device is unlocked, the reed switch is turned off at a certain distance to detect the open state of the window. This distance is referred to as an “unlocked lock detection distance”, and an unlocked state can be detected if a window is opened beyond this unlocked lock detection distance.
[0007]
However, the distance between the reed switch and the magnet varies depending on the type of the window, and if the distance between the reed switch and the magnet changes, naturally, this empty lock detection distance also changes. Therefore, the sensitivity of the empty lock detection may change depending on the type of window, or the empty lock detection may not be possible.
[0008]
This invention is made | formed in view of the said reason, The objective is to provide the crime prevention system which can perform an empty lock detection stably irrespective of the kind of sliding door.

[0015]
Further, inside the apparatus main body 100a, a micro switch 17 (see FIG. 2) is provided that turns on the contact if the slide lever 6 that locks the handle 5 in the locked position is in the locked position. That is, the microswitch 17 detects whether or not the slide lever 6 is in the lock position and is in the double lock state.
[0016]
FIG. 2 shows the circuit configuration of the circuit unit, which will be described next.
[0017]
The circuit provided on the window locking device 100 side includes a reed switch 12 and a micro switch 17, a notification unit 7 including the buzzer, and signal processing of detection signals of the reed switch 12 and the micro switch 17 on the window locking device 100 side. From the signal processing unit 20 composed of a microcomputer responsible for control processing including drive control of the notification unit 7 comprising a buzzer, from the signal processing unit 20 corresponding to the detection signal of the reed switch 12 and the detection signal of the micro switch 17 The reference frequency and the like are controlled by the radio transmission unit 21 that modulates the output detection data and transmits it via the antenna 25 by a wireless signal of a predetermined format using radio waves as a medium. Stores the PLL control unit 22 that controls the transmission frequency and the operation program and necessary data of the signal processing unit 20 And a storage unit 23, and a manipulation section 24 including the switch SW.
[0018]
The signal processing unit 20 determines whether the window is closed or opened by the window bodies 2, 2 ′ from the detection signal of the reed switch 12 and further doubles from the detection signal of the micro switch 17. A function for determining whether or not the device is in a locked state, a function for controlling the driving of the notification unit 7 based on the determination result, and a detection signal input from the reed switch 12 and the micro switch 17 as wireless detection data in a predetermined format. A process for outputting to the transmission unit 21 and a function for controlling the PLL control unit 22 are provided.
[0019]
Note that the switch SW is a switch for setting whether or not a warning sound to be described later is to be notified from the notification unit 7, and is set to be turned on in conjunction with the mechanical when the slide lever 6 is moved to the lock position side. It has become. Conversely, when the operation button 9 of the switch SW is turned off from the on state, the slide lever 6 of the lock means is mechanically moved to the unlock position in conjunction with the off operation. This configuration is not particularly shown, but an appropriate configuration may be used.
[0020]
By the way, the crime prevention system of this embodiment receives the wireless signal transmitted from the window locking device 100 side, and opens / closes the window based on the detection data corresponding to the detection signals of the reed switch 12 and the micro switch 17 included in the wireless signal. Etc., and a main controller (not shown).
[0021]
Next, the operation of the crime prevention system of the present invention will be described.
[0022]
First, when the window bodies 2 and 2 ′ are moved to a predetermined position so as to close the window, the reed switch 12 of the apparatus main body 100a close to the magnet 11 on the window body 2 ′ side indicates that the window is closed. The detection signal is output as a switch output.
[0023]
Then, as shown in FIG. 1, the crescent 3 of the crescent lock 1 on the window body 2 side is locked and locked to the receiving member 4 on the window body 2 'side, and the slide lever 6 of the locking means is slid downward. When the crescent lock 1 is locked, the microswitch 17 outputs a detection signal indicating that the lock state of the crescent lock 1 is locked as a switch output. At this time, as described above, the switch SW is mechanically interlocked and turned on.
[0024]
In this state, every time the double lock is turned on / off by the slide lever 6, the detection signal is transmitted to the main controller, and an alarm sounds on the main controller side depending on the mode on the main controller side. In addition, the buzzer of the alerting | reporting part 7 of the window locking apparatus 100 does not sound by ON / OFF operation of a double lock.
[0025]
Regardless of the mode on the main controller side, the buzzer of the notification unit 7 sounds when the window is opened when the operation button 9 of the switch SW is on, or when the operation button 9 is turned on when the window is open. This buzzer continues to sound until the operation button 9 is turned off or the battery is exhausted. The on / off operation of the operation button 9 is not transmitted to the main controller.
[0026]
Next, the basic operation of the empty lock detection of this embodiment will be described. Note that the spacer SP1 is omitted in FIGS. 3A, 3B, and 4. First, FIG. 3A shows a state when locked from below, and the window locking device 100 is attached to the side surface of the vertical rail 2a of the window body 2 having a sliding door structure, and the glass body 10 is attached to the window body 2. FIG. It is inserted. On the other hand, a plate-like magnet 11 is attached to the side end portion of the glass 10 ′ on the side of the window body 2 ′ constituting a sliding window together with the window body 2. The crescent 3 is locked to the support 4 with the window closed.
[0027]
FIG. 3B shows the locked state as viewed from above. The reed switch 12 is in a position facing the magnet 11 and detects the closed state of the window.
[0028]
Next, FIG. 4 shows the state when unlocked as viewed from below. The window is not completely closed, and the crescent 3 is not locked to the support 4 and is rotated to the locked position. ing. At this time, the reed switch 12 is driven by the magnet 11 to detect the closed state of the window until it opens more than the empty lock detection distance La0, and detects the opened state of the window when it opens more than the empty lock detection distance La0. When the crescent 3 is rotated to the locked position and the slide lever 6 is moved to the lock position side with the window opened for the empty lock detection process La0 or more, the detection signal of the reed switch 12 indicates the open state of the window. Since the detection signal of the switch 17 indicates the locked state, the signal processing unit 20 determines that the lock is unlocked and causes the notification unit 7 to notify the warning sound indicating the lock. That is, the person operating the slide lever 6 is immediately notified that it is an empty lock.
[0029]
If the warning sound is heard and it is known that the lock is unlocked, the signal processing unit 20 notifies the signal processing unit 20 because the detection signal of the micro switch 17 becomes a signal indicating the unlock position by moving the slide lever 6 to the unlock position. The notification of the unit 7 is stopped. Alternatively, even when the switch SW is turned off, the lock is released in conjunction with the notification, and the notification is similarly stopped.
[0030]
On the other hand, if the unlocked state is not resolved after a certain period of time, the signal processing unit 20 drives and controls the notification unit 7 so that a warning sound with a larger volume is notified from the warning sound, and data indicating abnormality at the same time Is transmitted from the wireless transmission unit 21 to the main controller with a wireless signal.
[0031]
When the main controller receives the data indicating this abnormality, the main controller determines that an abnormality has occurred in the window, notifies a warning sound indicating the occurrence of the abnormality, and performs a corresponding display.
[0032]
Here, FIG. 5 shows an ON region A1 at the lower limit of the sensitivity value of the reed switch 12, an ON region A2 at the center of the sensitivity value, and an ON region A3 at the upper limit of the sensitivity value. Are turned on in the areas A1, A2 and A3. The circular ON regions at the upper and lower limits of the moving value have a difference in radius M1. The section where the magnet 11b disposed near the reed switch 12 is turned on with respect to the moving direction X of the window than the magnet 11a attached to the glass 10 ', that is, an empty lock. The detection distance becomes longer. Therefore, in the type of window in which the distance between the magnet 11 and the reed switch 12 is different, the empty lock detection distance La is different.
[0033]
Therefore, in the present embodiment, as shown in FIG. 6, in the case of a single plate glass window in which the distance between the magnet 11 and the reed switch 12 is Y1max, the spacer having a thickness Y3 is provided between the magnet 11 and the glass 10 ′. By interposing SP1, the distance between the magnet 11 and the reed switch 12 is set to a predetermined distance Y2.
[0034]
On the other hand, as shown in FIG. 8, in the case of a multi-layer glass window where the distance between the magnet 11 and the reed switch 12 is Y1min (<Y1max), the magnet 11 is directly attached to the inner glass 10 ′. The distance between the magnet 11 and the reed switch 12 is Y2 as in FIG.
[0035]
As described above, when the distance between the magnet 11 and the reed switch 12 is long, the spacer SP1 is interposed between the magnet 11 and the glass 10 ', and the distance between the magnet 11 and the reed switch 12 is set to a predetermined value. The lock detection distance corresponding to FIGS. 6 and 8 is the same lock detection distance La1 as shown in FIG. 7 (corresponding to FIG. 6) and FIG. 9 (corresponding to FIG. 8). Even if the type is different, the empty lock detection distance does not change. Therefore, it is possible to stably detect the empty lock regardless of the type of window.
[0036]
(Embodiment 2)
The overall configuration of the present embodiment is the same as that shown in FIGS. 1 and 2, and the same components are denoted by the same reference numerals and description thereof is omitted. In this embodiment, the spacer SP1 of Embodiment 1 may or may not be used.
[0037]
In the present embodiment, a spacer SP2 having a length X1 is provided on the side of the window body 2 ′ so that the crescent 3 protrudes from the front end of the receiving member 4 to the opposite side when the window is opened. When the crescent 3 faces the spacer SP2 in an empty lock state, the spacer SP2 interferes with the rotation trajectory of the crescent 3 so that the crescent 3 cannot be physically rotated to the locked position. If the window is opened by a distance La3 or more, the spacer SP2 does not interfere with the crescent 3.
[0038]
Accordingly, in the unlocked state, the crescent 3 cannot be rotated to the locked position unless the window is opened by the distance La3 or more, and the person who operates the crescent 3 notices that it is an empty lock. Further, this distance La3 is longer than the empty lock detection distance La0 shown in FIG. 4, and even when the opening distance of the window is equal to or less than the empty lock detection distance La0, it is noticed that it is empty lock.
[0039]
When the window is opened by the distance La3 or more, the detection signal of the reed switch 12 is detected as in the first embodiment by rotating the crescent 3 to the locking position and moving the slide lever 6 to the unlocking position. Since the open state of the window is indicated and the detection signal of the micro switch 17 indicates the locked state, the signal processing unit 20 determines that the lock is unlocked, and causes the notification unit 7 to notify a warning sound indicating the empty lock. That is, the person operating the slide lever 6 is immediately notified that it is an empty lock. Subsequent processing is the same as that of the first embodiment, and a description thereof will be omitted.
[0040]
In the first and second embodiments, the microswitch 18 (see FIG. 1) is turned on when the handle 5 is rotated in the locking direction and the crescent 3 is in the locking position (the state shown in FIG. 1). 2), the microswitch 18 detects that the crescent 3 is in the locked position or the unlocked position, the detection signal of the reed switch 12 indicates the open state of the window, and the detection signal of the microswitch 18 If it is in the state indicating the locked position, the signal processing unit 20 may determine that it is an empty lock.
[0041]
In the first and second embodiments, the window locking device 100 and the receiver 4 are provided on the window body 2, 2 ′ side, but either one of the window locking device 100 and the receiver 4 is provided on the window body side, Any one of them may be provided on the side of a building such as an indoor wall surface.
