Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an alarm device for crime prevention, alarm, etc. provided at openings such as windows and entrances and exits of buildings.

(Prior art) Conventionally, this type of alarm device is equipped with an operating switch that turns on and off in conjunction with the opening and closing of the shoji at the opening of the building, so each time the shoji is opened and closed,
There is an inconvenience that the activation switch is activated to close the alarm circuit and issue an alarm. Therefore, it is possible to turn off the activation switch so that it does not operate when it is not necessary, but even if it is closed, if it is in the OFF state, it will not activate the alarm when necessary for crime prevention etc. Therefore, when you are away from home or in bed, you have to open and close the operating switch, which is a hassle, and there is a drawback that malfunction or non-operation may occur due to forgetting to operate the switch.

(Problems to be Solved by the Invention) Therefore, in view of the above-mentioned conventional drawbacks, the present invention solves the problems and eliminates the trouble of manually switching the operating switch, and provides a reliable alarm when necessary. The goal is to obtain an alarm system for building openings that can emit alarms.

(Means for Solving the Problems) As a means for achieving this, the present invention provides a signal generator installed between a shoji installed in an opening of a building and a corresponding shoji or sash frame. It consists of an operating switch, a touch-type switch for preventing signal generation, which is disposed on the opening/closing operation grip part of the shoji, and a control circuit that interrupts the circuit of the signal generator by energizing the touch-type switch.

(Example) An example in which a specific configuration of the present invention is shown in the drawings will be described in detail below.

FIG. 3 is a block diagram of the notification device 1 of the present invention, in which a signal generation circuit 2 includes an actuation switch 3, a well-known output increaser 4, and an alarm 5 which is a signal generator.
and a touch plate 7, which is a touch type switch.
It consists of a flip-flop 8 and a control circuit 6 having a circuit opening/closing section 9. The operating switch 3 is composed of a micro switch 10 and a detection protrusion 11. The micro switch 10 is attached to the matching stile B of the inner shoji A of the sliding shoji, and the detection protrusion 11 is attached to the upper stile D of the corresponding outer shoji C. Install. Also, the alarm 5 may be installed together with the power increaser 4 in a case containing the micro switch 10, or
Separately, it is built into the connecting frame B. On the other hand, the touch plates 7 are made of conductive wire material, and two touch plates 7, 7 are installed on the indoor side of the stile B of the inner shoji A in close proximity to each other in the vertical direction and are insulated from each other.
Then, connect the other touch plate 7 to the input terminal of flip-flop 8, and connect the other touch plate 7 to the input terminal of flip-flop 8.
The output terminal of the transistor T which is the circuit opening/closing part 9
Connect to the base of A relay coil 12 and a self-holding switch 13a are connected in series between the collector of the transistor T and a power source E, and an operating switch 3 is connected in parallel to the self-holding switch 13a. Connect to flip-flop 8. Further, a normally open relay switch 13b operated by a relay coil 12 is connected between the power source E and the output amplifying section 4 of the signal generating circuit 2.

With this structure, if one of the shojis is opened without touching the touch plates 7, 7, the micro switch 10 of the operating switch 3 is pushed when it passes the detection protrusion 11, and the switch circuit is closed. will be accomplished. This closure causes current to flow, activating the transistor T, and energizing the relay coil 12, thereby closing the self-holding switch 13a and the relay switch 13b. Therefore, even if the micro switch 10 passes through the detection protrusion 11 and the switch circuit becomes open, the relay switch 13b is closed by the self-held relay coil 12. The alarm device 5 such as a buzzer is continuously energized and generates an alarm sound. This makes it possible to notify of illegal intrusion from the outside.

In addition, if the resident wishes to open either the inner or outer shoji A or C without activating the alarm 5, he or she may straddle the touch plates 7, 7 and touch them with his/her hand or fingers to open the door stile B. grasp. When any of the shoji doors is opened in this state, the micro switch 10 of the operating switch 3 is pushed when it passes the detection protrusion 11, and the switch circuit is closed. At this instant, current flows through the touch plates 7, 7, which are in contact with each other through the hand or finger, and actuates the flip-flop 8. The operation of the flip-flop 8 cuts off the current to the transistor T, demagnetizes the relay coil 12, and keeps the relay switch 13b open. Therefore, when the shoji is open, the micro switch 10 climbs over the detection protrusion 11 and the switch circuit is also open, so the power to the alarm 5 is cut off and the alarm is turned off. 5 doesn't ring.

In addition, the resident mistakenly touched touch plates 7 and 7.
If the alarm 5 is opened without touching the touch plates 7, the alarm 5 will operate and generate an alarm sound as described above, but in order to stop the alarm 5 from operating, the touch plates 7 and 7 must be electrically connected. Just do it. Then, the flip-flop 8 operates to cut off the power to the transistor T, the relay switch 13b becomes open, and eventually the power to the alarm device 5 is also cut off and the alarm device 5 stops emitting an alarm sound.

By the way, when the shoji is opened without the alarm 5 sounding, its circuit is in the same state as the shoji when it is closed, as shown in FIG. Therefore, if you try to close the shoji as it is, the operation switch 3
is activated, causing alarm 5 to sound. Therefore, in order to close the alarm without sounding the alarm 5, both the touch plates 7, 7 are brought into a conductive state. In this way, the flip-flop 8 operates to keep the relay switch 13b open in the same way as when opening the shoji, and the shoji can be closed without causing the alarm 5 to sound.

FIG. 5 shows another embodiment, in which the operating switch 3 is activated when the touch plates 7, 7 are electrically connected when the shoji is opened.
At the same time, the conduction state is maintained, and even if the shoji is closed without touching the touch plate, the alarm will not sound, and the conduction state will be canceled by the operation of the activation switch, and each circuit will be in a standby state. It incorporates a changeover switch circuit 14 that alternately turns on and off in conjunction with the operating switch 3. In this case, when the changeover switch circuit 14 is turned on, the relay coil 12 is energized via the flip-flop 8, and the relay coil 13 is turned on.
The alarm 5 is activated by closing b. In this operating state, even if the operating switch 3 is operated again by closing the shoji, the alarm 5 will not stop, so that a reliable alarm effect will be exerted against intrusion from outside. On the other hand, when the touch plates 7, 7 are made conductive, a signal is sent to the flip-flop 8, and the current from the changeover switch circuit 14 to the relay coil 12 is cut off.
Alarm 5 does not sound even if Even if the shoji is closed in this state and the operating switch 3 is operated again, the switch circuit 14 simply sends an off signal, so the alarm 5 does not operate. When the shoji is closed, all circuits return to their original standby state.

These examples work on sliding shoji,
The touch plates 7, 7 are attached to the indoor side of the door stop stile B, but the present invention is not limited to this, and they may be attached to the indoor side of the door stop side stile. It may be attached to a provided handle metal fitting. In addition to sliding sashes, it can be used in various openings such as doors, casement windows, single-sliding windows, etc. For example, in the case of a single-sliding window, the detection protrusion 11 is attached to the sash frame. In the case of door E, as shown in FIG. 6, a touch-type switch 7a is provided on the knob 15 on the indoor side.

Further, in the above embodiment, the signal generating device is an alarm device that emits a warning sound, but a chime or a signal light that emits a flickering light that is used at the entrance may also be used.

Instead of these, an electric signal oscillator may be used in conjunction with an alarm or signal light in a central control panel installed elsewhere.

(Effects of the Invention) As described above in detail with respect to the embodiments, in this invention, the touch-type switch is disposed in the operation grip part of the shoji, so that the touch-type switch can be touched naturally at the same time as the operation and grip of the opening/closing shoji. , can reliably cut off the operation of the signal generator,
This has an excellent effect in that it is possible to reliably prevent erroneous activation due to forgetting to operate the switch or non-activation of the alarm in an emergency without the need for the complicated operation of intentionally opening and closing the activation switch as in the conventional case.
