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 security device, various means for detecting a suspicious person by means of a human body detecting means and giving an alarm have been proposed in many cases, and some of them have been put to practical use. In this case, various attempts have been made on the human body detecting means or the warning means. As one example, for example, Japanese Patent Application Laid-Open No. 62-86669 proposes a lighting system for approaching a house aiming at both effects of crime prevention and power saving. In this technique, a human body sensor for detecting a human body entering the above-mentioned approach road is provided, and an illuminating lamp whose brightness is increased by the detection is installed on the above-mentioned approach road.

[0005] FIG. In FIG. 5, SP is a visitor (suspicious person), and when approaching the entrance FD from the house approach road after passing through the gate GD, the approach of the visitor SP is detected by infrared rays emitted from the human body sensor SH or the like. You. On the other hand, a changeover switch SM is installed indoors in conjunction with the human body sensor SH, and is wired so as to increase each brightness as the visitor (or suspicious person) SP approaches the entrance FD. The gate light LM, the porch light LP, and the hall light LH provided on the ceiling in the entrance hall R are sequentially turned on at high illuminance, so that when the intruder returns home during the night of the visitor or the resident, the approach path is reduced. In the case of a suspicious person, a safe passage is secured by the illumination of the vehicle, and automatic high-intensity lighting is performed, thereby warning the approach of the suspicious person as soon as possible to use as a crime prevention means.

[0004]

According to the above means,
By the combination of the switch and the circuit, the gate light LM, the porch light LP, and the hall light LH are respectively turned off or dimmed when no human body is present on the approach road, and a visitor or a suspicious person approached by the human body sensor SH is prevented. When it is detected, lighting or high-intensity illumination is performed, so that power is usually saved. In addition, when a suspicious person approaches, an alarm function is provided, so that the purpose of crime prevention can be achieved. However,
In order to achieve such a configuration, it is necessary to wire such signal lines in advance during construction.
In order to add such equipment after construction, for example, work such as breaking a wall is required, and the installation work becomes complicated.

[0005] One of the problems of the above-described configuration is that the human body sensor S is used especially when it is used for security purposes.
Depending on the attachment position of H, it is expected that a suspicious person will notice and bypass the sensor, making it impossible to detect or destroying the sensor in advance. Accordingly, it is an object of the present invention to provide a security device in which a human body detecting means can be installed relatively easily and in a manner that is less noticeable from the outside.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and has as its gist a human body detecting means for detecting a suspicious person approaching a window or a door from outside. And an alarm unit installed indoors that outputs an obtained detection signal as sounding or lighting and issues an alarm, wherein the sensor unit of the detection unit is located indoors on the glass surface of the window or door. The security device is disposed close to the glass surface while maintaining a distance from the glass surface. In this case, the sensor unit is incorporated in the adsorber and adhered to the glass surface, or attached to the tip of the arm. It is also effective to adopt either configuration of being integrated with the alarm unit and being adhered to the glass surface.

[0007]

According to the present invention, since the sensor of the human body detecting means is installed through the glass inside the window or the door, a large-scale house remodeling work is not required, and it is merely necessary to approach the inside of the glass surface. Attachment of the sensor section is sufficient, and installation is simple. In addition, since the sensor unit cannot be seen from the side of the suspicious individual, it is substantially difficult to find the arrangement of the security device from the suspicious individual. Further, in the present invention, it is not necessary to perform any special wiring work between the sensor section and the alarm section, so that the detecting means does not malfunction due to, for example, the influence of electric noise caused by the wiring, and the reliability is improved. Highly effective crime prevention function is exhibited.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. First, FIG. 1 is a schematic explanatory view showing a basic configuration of a security device of the present invention. In FIG. 1, 3

On the other hand, the sound of the speaker 9, the lighting of the lamp 7, or the outlet 1 is operated by the alarm stop button 10.
However, if the suspicious person does not leave after 10 seconds, for example, after the stop, the microcomputer 4 resumes the output, and each alarm is activated. The microcomputer 4 must be
In this case, the alarm section 2 can always be automatically restarted. Note that the stop button 10
The period from the pressing of the button to the reactivation of the alarm unit 2 is not limited to 10 seconds, and an appropriate period may be selected for each. When the suspicious person leaves and the output signal 5 of the human body detection sensor unit 1 is no longer output, the output of the microcomputer 4 is not output, and the alarm unit is turned off.
