Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a security sensor for glass plates that can be used for general-purpose glass windows, doors, and the like.

-1- Configuration of conventional example and its problems A conventional glass plate breaking sensor will be explained using FIG. 1. 1 is a glass plate breaking sensor, which is bonded with adhesive to a glass plate 2 of a fixed or rarely opened/closed glass window;
It is connected to the alarm device 3 via a lead wire 4.

However, in such a conventional configuration, since the lead wire 4 is fixed to the wall 5, the movement of the glass plate breaking sensor 1 is restricted, and it cannot be installed in cases where the glass plate 2 moves significantly, such as in sliding windows and doors. In such cases, only the sensor that detects the opening and closing of the door detects the intrusion of a thief.

Purpose of the Invention The present invention solves the above-mentioned drawbacks of the conventional art.It can be easily installed on windows and doors that could not be installed in the past, and can detect when a glass plate is broken, when a window or door is opened/closed, and when the entire window frame is removed. An object of the present invention is to provide a security sensor for a glass plate that can detect the falling off of parts, etc.

Structure of the Invention In order to achieve the above object, the security sensor for glass plates of the present invention has the following features. a receiving section mounted on a wall so as to be close to the detecting section; a detecting element disposed in the detecting section to detect an abnormality of the glass plate; and a detecting element disposed in the detecting section. a transmitting means for transmitting a signal from the transmitting means; a receiving means disposed in the receiving section for contactlessly receiving the signal transmitted from the transmitting means; and a receiving means disposed in the receiving section for detecting the presence or absence of the detecting section. The configuration includes a detection means.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

8 is a receiving circuit block, 19 is a power supply, 20 is an amplifier circuit,
21 is a switching circuit. The detection unit 6 is fixed to the glass plate 7 via an adhesive. The receiving section 8 is attached to the wall so as to be close to the detecting section 6 when the window or door to which the glass plate 7 to which the detecting section 6 is fixed is attached is in an open state as shown in FIG. . In this state, the light emitting element 9 and the light receiving element 10. and reflective photoelectric switch 11
and the reflecting mirror 12 face each other. Further, the receiving section 8 is connected to an alarm device 14 via a lead wire 13.

First, when the window or door to which the glass plate 7 is attached is in an open state, the reflective photoelectric switch 11 is turned off, and the alarm device 14 notifies an abnormality. The same applies if the entire window frame is removed even though it was locked, or if the detection unit 6 falls off.

Next, when the window or door is closed, when the glass plate 71 is broken or a detected shock vibration occurs, a mechanical-electrical transducer such as a piezoelectric body facing the glass surface through the case is used. The detection element 15 emits a signal, a switching operation is performed in the transmission circuit block 16 which receives the signal 13, and the light emitting element 9 emits light by the power from the power source block 17. The light emitting signal is received by the light receiving element 10 of the receiving section 8, and the receiving circuit block 1 old J
113, a switching operation is performed, and the lead wire 13
A glass breakage alarm is output to the alarm device connected via the

Note that when a bimetal is used as the detection element 15 and an attempt is made to burn out the glass plate 7, the bimetal deforms ( ) and closes the circuit, causing the light emitting element 9 to emit light and outputting an alarm.
"Shiru": Utoshi - Shiyoi. In addition, a detection element 15 consisting of a mechanical-electric conversion element such as a piezoelectric body is installed in a place where pressure is applied when the lock is applied. It is also possible to output it as a light emitting signal 8.Furthermore, any number of these various detection elements 113 may be provided.

In the circuit block diagram shown in FIG. 3, when the detection element 15 of the detection unit 6 detects some abnormality, the light emitting element 9 emits a signal, which is received by the light receiving element 5-10 in the reception unit 8. The output signal is amplified by the amplifier circuit 20, operates the switching circuit 21, and the alarm device 14 outputs an alarm.

At this time, one light-emitting element 9 and one light-receiving element 10 may be configured to issue an alarm if even one of the detection elements 15 that detect each state is activated, or alternatively, various detection elements may be used. The light emitting element 9 and the light receiving element 10 may be associated with the elements 15, respectively, and an alarm corresponding to the activated sensing element 15 may be output.

FIG. 4 is a perspective view showing how a security sensor for a glass plate is installed in an embodiment of the present invention, and 22 is a repeater. The detection parts 5a and 6b are arranged so that they do not interfere with the opening and closing of the window.
It is adhered to the upper limits of the glass plates 7a and 7b. Also, the detection unit 6a when the window is open.

Receiving units 8a and 8b are installed adjacent to 6b and are connected to the alarm device 14 via a repeater 22.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, the state of a window or door having a glass plate is sensed, and the information is sent to the receiving unit without contact (U). The security sensor can be installed against large moving intruders such as sliding windows, etc., and does not cause much trouble in handling windows, doors, etc., making it possible to obtain a more reliable security sensor.
