Description

  The present invention relates to a crime prevention device, and more particularly to a portable crime prevention device having a function of making it easy to recognize that it is being carried around.

JP 07-014494 JP 09-142350 A

  A battery, a buzzer driving circuit, a buzzer, and an emergency switch are built in a casing, carried in a pocket or a handbag, and connected to a power source by an emergency switch in an emergency to sound a buzzer (Patent Document 1). ). Among such devices, devices that can be carried by hanging from the neck with a strap so that the emergency switch can be operated quickly, or can be carried by being fixed to clothes or school bags are also popular. However, the buzzer is effective only after the wearer feels dangerous, but it is insufficient to prevent it before it feels dangerous. On the other hand, a lighting device equipped with a vibration sensor attached to a moving body is known (Patent Document 2).

An object of this invention is to aim at the effect of reducing a criminal intention by making the surrounding passerby, especially the pervert person, recognize before carrying a crime prevention device.

In order to achieve the above object, the present invention has the following configuration. The portable crime prevention device according to claim 1 is a crime prevention device including a battery, a buzzer, an emergency switch, a light emitter, and a vibration sensor, and the light emitter is surrounded by an operation of the vibration sensor. It emits light so as to be visible.
The portable crime prevention device according to claim 2 is the portable crime prevention device according to claim 1, wherein the light emitter is operated a predetermined number of times in a predetermined time by a monitoring circuit that monitors the operation of the vibration sensor. It is characterized by emitting light when exceeding.
According to a third aspect of the present invention, there is provided the portable security device according to the second aspect, wherein the monitoring circuit starts monitoring with the operation of the vibration sensor as a trigger.
A portable security device according to a fourth aspect is the portable security device according to the first to third aspects, wherein the light emitter emits light for a predetermined time determined by a timer circuit. A portable security device according to a fifth aspect is the portable security device according to the fourth aspect, wherein the light emitter is blinked by a blinking circuit.
A portable crime prevention device according to a sixth aspect is the portable crime prevention device according to the first to third aspects, wherein the buzzer and the flashing circuit are activated by an emergency switch.
The portable crime prevention device according to claim 7 is the portable crime prevention device according to claim 5, wherein the light emitter is configured to be separated from at least a casing for storing a battery and a buzzer. To do.

The portable crime prevention device according to the present invention pays attention to the flashing light-emitting body even from a distant position, and recognizes that the crime prevention device is being carried. In particular, it can be expected that the perpetrators will be reduced before the perverts approach.
In the unlikely event of an emergency, the buzzer sounds and the illuminant is lit or blinked simultaneously and continuously, so it is easy to convey the occurrence of danger.
Furthermore, since the monitoring circuit eliminates unnecessary light emission, it does not interfere with sleeping or sleeping when going to bed, concentrating on classes or work in the classroom or office.

  FIG. 1 shows a first embodiment of a portable security device according to the present invention. A clip 10a is provided. In FIG. 1, the housing 1 is box-shaped, and the opening 1 b for the light-emitting diode 5 is provided only on one surface, but it may be arranged so as to be visible from a plurality of directions. Further, by providing a plurality of light emitting diodes 5, it is possible to display characters and display images, for example, the characters “carrying security buzzer” may be displayed.

  FIG. 2 shows a second embodiment of the portable security device according to the present invention, in which the light emitting diode 5 is separated from the housing 1 and provided as the light emitting unit 12 at the end of the strap 10. As a result, the casing 1 of the main body portion having a comparatively heavy weight and size and the light and small light emitting unit 12 can be separately carried.

FIG. 3 is a conceptual diagram of the portable security device circuit according to the first embodiment. When walking, the voltage of the battery 2 is supplied to the vibration sensor 6, the monitoring circuit 7, the timer circuit 8, and the blinking circuit 9, and the light emitting diode 5 blinks. It becomes a state. The emergency switch pieces 4a and 4b have their circuits opened by an insulating piece 9b provided at one end of the strap 9, so that the buzzer 3 does not ring. When the strap 10 is pulled out in an emergency, the emergency switch pieces 4a and 4b are elastically closed, whereby the voltage of the battery 2 is also supplied to the buzzer 3 so as to blink and sound.
FIG. 4 is a conceptual diagram of a portable security device circuit according to the second embodiment. The light emitting diode 5 is connected to the blinking circuit 9 via a conductive wire 11 arranged in the strap 10. Since this conducting wire 11 has a sufficient length in the housing 1, even if the strap 10 is pulled out in an emergency, it will be in a blinking and ringing state.

In the first embodiment, the clip 10a of the strap 10 can be hung on a school bag, for example. Once the user starts walking, the vibration sensor 6 is activated by detecting the walking, and after a predetermined time determined by the monitoring circuit 7, the voltage of the battery 2 is supplied to the light emitting diode 5 to emit light. This light emission is visible to the outside through the opening 1 b of the housing 1. Since the voltage of the battery 2 is supplied to the light emitting diode 5 through the monitoring circuit 7, the timer circuit 8, and the blinking circuit 9, the battery 2 is in a blinking state for a predetermined time determined by the timer circuit 8. For this reason, for example, even when walking is stopped due to waiting for a signal or the like, the blinking continues. However, since the school bag is turned off after a certain period of time after leaving the school, it does not interfere with the lesson. Even if the school bag is moved by some force during the class, the monitoring circuit 7 does not supply the voltage to the diode 5 until the number of operations of the vibration sensor 6 exceeds a predetermined number of times in a certain time. do not become. Since the monitoring circuit 7 starts monitoring with the operation of the vibration sensor 6 as a trigger, it is possible to prevent battery consumption.
For example, if the monitoring time of the monitoring circuit 7 is 5 seconds and the blinking time of the timer circuit 8 is 5 minutes, the blinking will continue when waiting for a signal at the time of attending school, etc. Even if something or a person collides with the school bag, flashing does not start unnecessarily.
In the event of an emergency, when the user pulls out the insulating piece 10b, the emergency switch pieces 4a and 4b are closed, and the voltage of the battery 2 is supplied to the buzzer 3 and the flashing circuit 9. The state continues.

Further, in the second embodiment, the casing 1 of the main body part having a relatively heavy weight and size is stored in the handbag, and only the light and small light emitting part 12 is exposed from the handbag and used. Carrying can be simplified without impairing visibility.
In the event of an emergency, the light emitting unit 12 that is integral with the strap 10 is exposed, so there is no difficulty in grasping and pulling out the light emitting unit 12.
