Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security device, and more particularly to a security device capable of detecting a suspicious person approaching a window or a door from outside and issuing an alarm.

[0002]

2. Description of the Related Art With regard to a crime prevention device, various means for detecting a suspicious person by means of human body detection means and issuing an alarm have already been proposed and partially put to practical use. In this case, various attempts have been made for human body detecting means or alarm means. As one example thereof, for example, Japanese Patent Laid-Open No. 62-86696 proposes a lighting device for a house approach road aiming at both the crime prevention and the power saving effect. In this technique, a human body sensor for detecting a human body entering the approach road is provided, and an illumination lamp whose brightness is increased by the detection is installed in the approach road.

A schematic explanatory view thereof is shown in FIG. In FIG. 6, SP is a visitor (suspicious person), and when passing through the gate GD and approaching the entrance FD from the entrance path of the house, the approach of the visitor SP is detected by infrared rays emitted from the human body sensor SH. It On the other hand, a changeover switch SM is installed indoors in association with the human body sensor SH, and is wired so as to increase the brightness of each visitor (or suspicious person) SP as it approaches the entrance FD. The gate light LM, the porch light LP, and the hall light LH installed on the ceiling in the entrance hall R are sequentially turned on with high illuminance, so that the approach road can be used when the intruder returns home at night by the visitor or the resident. In order to secure a safe passage by using the above-mentioned illumination, and in the case of a suspicious person, a high-intensity light is automatically turned on to quickly warn the approach of the suspicious person and use it as a crime prevention means.

[0004]

According to the above means,
Depending on the combination of the switch and the circuit, the gate light LM, the porch light LP, and the hall light LH are turned off or dimmed respectively while no human body is present on the approach road, so that the human body sensor SH can detect a visitor or a suspicious person approaching. When detected, lighting or high-intensity lighting is performed, which usually saves power, and also acts as an alarm when a suspicious person approaches, thus achieving the purpose of crime prevention. However,
In order to have such a structure, it is necessary to wire such a signal line in advance at the time of construction.
In order to add such equipment after construction, it is necessary to perform work such as breaking the wall, which makes installation work complicated.

In addition, as one of the problems of the above-mentioned configuration, in the case of rain, for example, when a raindrop passes in front of the human body sensor SH, a malfunction such as detection of this and activation of an alarm or the like occurs. There are cases where this is unavoidable in the above configuration. Further, particularly when used for the purpose of crime prevention, depending on the mounting position of the human body sensor SH, a case in which a suspicious person is noticed and bypasses the sensor and detection becomes impossible may be expected. Therefore, it is an object of the present invention to provide a crime prevention device in which the human body detecting means can be installed relatively easily and in a manner that is inconspicuous from the outside.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and its gist is to provide a human body detecting means for detecting a suspicious person approaching a window or door from the outdoors. And a warning device installed indoors for outputting the obtained detection signal as a sound or lighting to issue an alarm, wherein the sensor unit of the detection unit is embedded in an outer frame of a window or a door. A security device in which the alarm means and the sensor section are connected via a conductive means that is expandable and / or slidable, and a reflector is arranged at a predetermined position facing the sensor section. In this case, the outer frame is an aluminum sash, and the slidable conductive means is composed of a sliding brush attached to the outer frame rail side and a rail in which a signal line is embedded. , Both of which are valid.

[0007]

In the present invention, since the sensor part of the human body detecting means is embedded in the outer frame of the window or door, a large-scale remodeling work of the house is not required, and the outer frame is simply processed to make the sensor part. It is enough to install the and the installation is easy. Moreover, since the suspicious person cannot see anything other than the infrared ray entrance / exit holes of the sensor section, it is substantially difficult for the suspicious person to discover the arrangement of the security device. Furthermore, in the present invention, a reflection plate is arranged at a predetermined position facing the sensor unit, and a method of detecting a suspicious person by scattering infrared rays by blocking a suspicious person between the sensor unit and the reflection plate. Since it is used, for example, in the case of rainy weather, the detection unit does not malfunction due to the effect of raindrops, and a highly reliable crime prevention function is exhibited.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings. First, FIG. 1 is a schematic explanatory view showing a basic configuration of a crime prevention device of the present invention. In FIG. 1, reference numeral 3 is a suspicious person, and the sensor unit is composed of a human body sensor section mainly composed of a human body detection sensor 1 and a reflection plate 2 attached at a predetermined position facing the sensor 1. It In this case, the mounting position, distance, etc. of the reflector 2 may be selected appropriately depending on the structure of each house, installation location, and the like. For example, when the detection sensor 1 is embedded in a window frame with a veranda or the like, the reflection plate 2 may be attached at a position such as a handrail of the veranda, which is away from the sensor by a distance of about 2 to 3 m, which is an effective range of infrared rays. Good to do.

As will be described later, the human body sensor unit is specifically connected to the crime prevention device body unit via a signal line and further a sliding member. In this security device body,
A microcomputer 4 used as the human body detection sensor 1, for example, for receiving a suspicious person detection output pulse 5 from an infrared active sensor, a relay device 6 for controlling an alarm display lamp 7 controlled by the microcomputer 4, and an alarm. A driver device 8 for controlling a speaker 9 for generating sound is connected. In the figure, 10
Is an alarm stop button for stopping the alarm.
Is a power supply circuit.

Next, regarding the operation of the security device shown in FIG.
Description will be made with reference to FIG. First, as shown in a specific example to be described later, infrared rays are emitted from an infrared active sensor 1 which is a human body detection sensor embedded in a sash outer frame, and the infrared rays are reflected by a reflector 2. The reflected infrared rays are received by the infrared active sensor 1. When the suspicious person 3 passes in front of the infrared active sensor 1, the emitted infrared rays hit the suspicious person 3 and the infrared rays are scattered in all directions, so that the infrared active sensor 1 cannot temporarily receive the infrared rays. At this time, the infrared active sensor 1 causes the microcomputer 4 to generate a suspicious person detection output pulse 5. The light emitting line in this case may be other than infrared rays as long as it has the same effect.

Upon receiving the suspicious individual detection output pulse 5, the microcomputer 4 controls the relay device 6 to turn on the lamp 7 connected to it, and the microcomputer 4 controls the driver device 8 to control it. Sound is output from the connected speaker 9. By these,
Notify people indoors. Also, the alarm stop button 10
Thus, the sound of the speaker 9 and the lighting of the lamp 7 can be stopped. The security device of the present invention is basically capable of detecting the approach of a suspicious person by the above-described operation. Next, a security device based on these is attached to the outer frame of the window or door. Examples will be described with reference to the drawings.

FIG. 2 is a schematic perspective view of an embodiment showing a state in which the sensor portion 1 of the human body detecting means in the crime prevention device of the present invention is embedded in an outer frame 11 of a window such as an aluminum sash. FIG. 3 is an enlarged cross-sectional view of part A of FIG. 2. 2 and 3, 11a is an indoor side window frame and 11b is an outdoor side window frame. In the illustrated example, the sensor unit 1 is embedded in the indoor side outer frame 11a as shown in the sectional view of FIG. And
An opening 18 which is an entrance for receiving and transmitting infrared rays from the sensor unit 1 is provided facing the outdoors. The infrared rays are sent out from the openings, reflected by a reflector (not shown), and the reflected infrared rays are received by the openings. On the other hand, 14 is an alarm device provided indoors, which includes the alarm lamp 7 shown in FIG.
The speaker 9 and the alarm stop button 10 are provided. Between the alarm device 14 and the human body detection sensor 1 embedded in the outer frame 11b, a signal line 13 which can be expanded and contracted via a signal outlet 12 arranged on the indoor side of the outer frame 11a.
And the detection output signal from the sensor unit 1 is sent to the alarm device 14. In the figure, 21 is glass, 19
Is a rail groove.

In this case, the reason why the signal line 13 can be expanded and contracted is that it can cope with opening and closing of windows or doors. Also,
In FIG. 2, since the sensor unit 1 is embedded in the indoor side outer frame 11a, the sensor unit 1 is hidden behind the outdoor side outer frame 11b when the window is opened, and the sensor unit 1 is not shown in the drawing against a reflector. It will be blocked, and an alarm will be issued with the same effect as if a suspicious person approaches the closed window or door across the infrared. This is because even if a suspicious person approaches a window or the like and opens it at night without being detected by the sensor unit 1 and tries to intrude secretly at night, the alarm still activates the purpose of crime prevention. Is meant to be done.

Further, since the relative position of the reflector (not shown) and the sensor unit 1 is set to a predetermined position in advance, the reflector is moved even if the window frame 11b is moved to a slightly open state, for example. Since the relative position between the sensor unit 1 and the sensor unit 1 is deviated, infrared rays cannot be received, so that the alarm is activated and the intended purpose is achieved. As described above, as shown in FIG. 3, since the opening 18 of the sensor unit 1 needs to be a hole having a very small diameter, the security device is installed in a position that is virtually unnoticeable by a suspicious person. It becomes possible to do. In addition, as the outer frame material of the window or door, a so-called aluminum sash that uses aluminum has been fairly generalized in recent years, but if there is no problem in processing, it is not possible to apply the present invention to a wooden or steel sash. Of course it is possible.

Next, another embodiment of the security device of the present invention will be described with reference to the drawings. FIG. 4 is a schematic perspective view showing an example of one embodiment of a slidable conductive means at the time of connecting the sensor unit 1 and the alarm device 14 in the security device of the present invention, and FIG. It is a principal part expansion conceptual perspective view. The outer frame 11, the sensor unit 1, and the alarm device 14 in FIG.
The arrangement is the same as in the case of FIG. Reference numeral 15 is a rail, and 13 is a signal line. The sliding portion and the conductive means in this case are as illustrated in FIG.

That is, the signal line 13a connecting from the sensor portion 1 embedded in the outer frame 11a to the sliding portion below the outer frame 11a is a hollow portion inside the outer frame 11a or the outer frame 11a.
It is attached to the indoor side of a, and one end of it is a sliding brush 1.
6 is connected. This sliding brush 16 is always a rail 15
It is arranged so as to come into contact with
There are three grooves for D, DC supply, and transmission / reception. Sliding brush 1
Reference numeral 6 is three metal pieces corresponding to the three grooves of the rail 15. Therefore, the sliding brush 16 and the rail 15 are always in contact with each other, and they play the same role as the signal line. Therefore, the alarm device 14 and the human body sensor 1 use the sliding rail 15 and the sliding brush 16 as contacts. The signal line system allows signals to be exchanged at all times. The signal line 13b from the alarm device 14 can be fixed to the end of the rail 15 with a screw 17 or the like.

When the signal line 13b is fixed to the rail 15 with the screw 17 as shown in FIG. 4, the relative position between the screw fastening portion and the alarm device 14 generally does not change. It is not necessary to make it extendable and retractable, but for other purposes, in addition to the sliding means of the system of FIG.
It does not prevent making the telescope flexible. In addition, by connecting the signal line 13 to the outlet 12 in the method of FIG. 2, and further by fixing the signal line 13b to the rail 15 with the screw 17 in the method of FIG. 4, both are for human body detection. Since it is possible to easily connect between the sensor unit 1 and the alarm device 14, since the sensor unit 1 itself is embedded in a removable building window frame (sash) or the like,
Even after the construction is completed, the crime prevention device can be easily installed only by replacing the sensor part with the embedded outer frame at any time.

[0018]

As is apparent from the above description, in the security device of the present invention, the human body detection sensor is mounted inside the window such as the aluminum sash, so that it is not conspicuous and suspicious person does not notice. In addition, there is no need for construction such as making holes for wiring the human body detection sensor outdoors and the alarm device indoors.
Easy to install. Furthermore, it is possible to avoid malfunctions caused by raindrops in case of rain. Thus, the practical value of the security device of the present invention is extremely remarkable.
