Description

DETAILED DESCRIPTION OF THE INVENTION (Object) The present invention relates to a snatch prevention device used for bags.

There is no end to the snatching cases of handbags for women walking alone. There are also cases where businessmen run away with a suitcase containing valuable materials at airports and business districts. Although the theft of cash and the like in these bags is a great loss, the theft of materials that cannot be replenished is sometimes a great loss that cannot be replaced with cash. In particular, when a bag is snatched by a plurality of people and relayed from person to person, it is difficult to track a runaway criminal.

Therefore, put a buzzer with a string in the bag, hold the tip of this string with the bag, and if the bag is slammed, the string comes out from the buzzer and the horn (buzzer sound) is smoothed to prevent snagging. Has been.
However, in reality, the carry-out person does not care for the buzzer sound, and when he / she removes the valuables inside, he picks up the bag with the buzzer sound and runs away. In particular, the criminal who aims at the bag of a woman walking alone at night uses a bicycle or a motorbike, and since she is far away from the victim immediately after snatching, the effect of the buzzer sound is small.

On the other hand, it is difficult for business people to use the buzzer as described above. Having both one end of the string and the handle of the suitcase is actually troublesome for the business man, and few people use the buzzer as a device to prevent snagging as described above.

Therefore, it is an object of the present invention to solve the above-mentioned problems of the conventional technology.

(Structure) In order to solve the above-mentioned problem, the present invention basically operates a high voltage generator by a signal from a transmitter,
Use a means to sound a siren (alarm) as the bag falls.

Specifically, the present invention relates to a transmitter carried by a person carrying a bag, a receiving section housed in the bag, a first power switch operated by a signal from the receiver, a first power switch and a power source. (EN) A snooping prevention device comprising a receiver having a high voltage generator and a siren generator, which are arranged in parallel with each other, and a switch with an acceleration relay for electrically connecting a power source to the siren generator.

When the bag snatches, the transmitter carried on the body is turned on, and the signal of the natural frequency is sent to the receiver of the receiver inside the bag. In response to this signal, the receiver turns on the first power switch, activates the high voltage generator, applies a high voltage (20KV-40KV) to the electrode protruding from the bag, and gives a voltage shock to the snatcher. . The criminal who received the voltage shock drops his bag, but the gravity at that time turns on the switch with the acceleration relay. Therefore, the power supply
Instead of the high voltage generator, it is electrically connected to the siren generator and sounds the siren. You can know the position of the bag by the sound of the siren.

(Embodiment) The snatching prevention device 1 comprises an oscillator 2 and a receiver 3, and the circuit of the oscillator 2 is a normal one having a high frequency oscillation circuit and an amplification transmission circuit, like the oscillator of a transceiver. Good. The transmitter 2 is combined with the receiver 4 of the receiver 3 and set to the natural frequency.

The receiver 4 is connected to the power supply 5 via a second power switch 6 that is always off. A first power switch 7 and an acceleration relay switch 8 are connected to both sides of the power supply 6. A high voltage generator 9 and a siren (or buzzer) 10 are connected in parallel between the first power switch 7 and the switch 8 with an acceleration relay.

The receiving unit 4 includes detection, amplification, and relay output circuits, similar to the transceiver receiving circuit.
Radio waves within 50 m can be received and can be linked with the first power switch 7. That is, when the signal from the transmitter 2 is received, the receiver 4 turns on the first power switch 7,
The high voltage generator 9 can be energized.

The normally open second power switch 6 can be manually turned on / off from the outside of the bag, and is turned on when the bag is used to activate the receiving unit 4. In the case of a handbag, the second power switch 6 may have a structure that is turned on when the shoulder strap is pulled.

The power supply unit 5 may be a small laminated dry battery. The high voltage generating unit 9 has an electrode 11 that goes out of the bag, and when it is energized, a high voltage of, for example, 20 KV-40 KV is generated at the electrode 11, and a voltage shock is given to the person holding the bag.

The switch 8 with acceleration relay is a mechanical magnetic type,
This is an application of an earthquake detector such as a spring type or a falling ball type. When the bag is dropped, the power source 5 can be switched and connected to the siren generator 10. The siren generator has a volume that allows a person within a 50 m radius to hear the sound.

Next, the usage will be described. When carrying a bag having the receiver 3 built-in and the electrodes exposed to the outside, the transmitter 2 is turned on and the second power switch 6 is turned on to activate the receiver 4. When a bag is caught or the case of carrying away, it immediately activates the transmitter 2 and sends a signal.
When the receiving unit 4 receives the signal, the first power switch 7 is turned on to electrically connect the power source 5 to the high voltage generating unit 9.
At this time, since a high voltage (20KV-40KV) is applied to the electrode 11, the person carrying the bag releases the bag due to this high voltage shock. When the gravity when the bag is dropped due to the release of the bag is sensed, the switch 8 with the acceleration relay operates to electrically connect the power source 5 to the siren generator 10 instead of the high voltage generator 9. Therefore, a siren sound (or a buzzer sound) is generated, and the position of the bag that has been carried away can be known.

The owner of the bag again can turn off the switch 6 to stop the siren sound.

(Effect) The snatch prevention device according to the present invention can be used not only for a handbag for women but also for a suitcase for businesspeople, attache cases, briefcases, etc. It is effective.

It is effective to prevent snagging because you cannot tell if you have a snag prevention device by just looking at the bag.
