The present invention relates to a multi-functional burglar alarm to prevent theft and lost accidents of various portable handbags, wallets, and the like.

In general, handbags and wallets are a necessity to store and carry a variety of money as necessities when going out. Naturally, handbags and wallets are subject to the crime of theft, and many people feel dangerous about such crimes. .

In practice, however, crime arrest rates are considerably low at such theft, due to the lack of reporting awareness and the absence of security devices against theft.

That is, in the past, there was no means to notify the surroundings even if they were stolen, and the anti-theft alarms that were previously devised have been partially disassembled and installed the burglar alarms. There is a problem that the storage space in the handbag is narrowed by embedding a bulky burglar alarm device in a small handbag, the present invention is to provide a burglar alarm that can cope with existing theft accidents as described above more wisely. Its features make it easy for anyone of all ages to use, the operation of the anti-theft alarm is sufficient to meet various conditions, so that theft can be prevented in any case, and it can also be used as an anti-lost alarm if necessary. The present invention, together with the accompanying drawings as follows Described in detail as follows.

The back of the main body 2 has a creep 12 which can clamp the main body 2 to a belt or suspenders when the anti-theft alarm 1 is used for preventing theft of a purse or the like. Attached.

The transmitter 3 is provided with an operation switch 13 and an emergency switch 14, and includes a transmission circuit section 15 such as the circuit diagram of FIG.

Hereinafter, the circuit configuration of each circuit component and the transmitter 3 in the burglar alarm 1 main body 2 will be described in detail.

The power supply circuit unit 4 connects the plug tweeter 11 of the main body 2 and the rechargeable battery 16 to use a DC 9V power supply, and the plug tweeter 11 naturally requires a charging adapter 19. Connect it to charge the power.

The receiving circuit unit 5 is configured to amplify the microwaves by connecting to the amplifier Q1 through an antenna (GREEN ANTENNA) for receiving the radio wave generated from the transmitter 3, and the tank (L1) to tune to a predetermined frequency ).

The radio waves tuned by the tank L1 are amplified by the amplifier 2Q and connected to the IC U1 circuit which summarizes the received values.

The IC U1 of the amplifying circuit section 6 is a signal change amplifying circuit which modifies and amplifies the radio wave guided by the amplifier Q2 into a predetermined signal and guides the IC U2.

The IC U2 of the received value cleaning circuit unit 7 is an IC for data retrieval, and a password (usually set to 4 digits) pre-inputted to the transmitting circuit unit 15 of the transmitter 3, and the setting number is set to It is a circuit that operates only when the value inputted to IC (U2) is the same. The IC U2 detects and receives the switching operation of the operation switch 13 and the emergency switch 14 of the transmitter 3 so that when the operation switch 13 is ON and the emergency switch 14 is ON, the IC U3 is detected. Induce signals and stop searching the circuit when they are OFF.

IC U31 is a circuit for controlling the alarm main body 2 and the emergency switch 14. The operation state indicator LED of the alarm main body 2 is emitted by the operation of the IC U3, and the sensor 17 Through the connected jack and plug, it is connected to the panel 18 connected to the handbag or purse, and connected to GND to generate a resistance. The resistance value causes the output to be stopped and the burglar alarm 1 is in the standby state. .

The IC U4 of the output sound oscillation circuit section 8 generates a fixed input sound, and the IC U4 generates sound and guides it to the amplifiers Q5, Q6 and Q7, and the transistor TR Induces negative elevations and time differences in the TRANS.

The transformer of the output amplification circuit unit 9 performs a high voltage generation function. When a high voltage is generated in the transformer, the transformer is supplied with current to the piezoelectric buzzer 10 to generate a high alarm sound. .

In the figure, reference numeral 19 is a charging adapter 20 shows a handbag.

The present invention, which can be configured as described above, can be largely divided into two types. First of all, the method of using the handbag 20 to prevent from theft will be described.

The main body 2 of the burglar alarm 1 is embedded inside the handbag 20, and a sensor 17 terminal connected to the plug 11 'of the main body 2 is embedded on the opening and closing of the handbag 20. When connected to the form, if the opening and closing method of the handbag 20 adopts a zipper and a plug-type detection sensor is adopted so that other people can be notified of the alarm when opening and closing the handbag 20.

Upon completion of the connection work of the main body 2 and the detection sensor 17 as described above in the handbag 20, the transmitter 3 is carried by the user separately and the ON switch 13 turns on the microwaves generated by the transmitter 3 Is received by the antenna (GREEN ANTENNA) of the main body (2), the microwaves received by the antenna (GREEN ANTENNA) are amplified firstly through the amplifier (Q1), guided to the tank (L1) and tuned to the specified frequency only amplifier To (Q2). The electric wave amplified by the amplifier Q2 induces the IC U1 for changing and amplifying the signal, and changes and amplifies the set signal to the data search IC U2.

The IC U2 for data retrieval operates only when the signal is the same as that of the transmitter 3, and simultaneously detects the operation of the operation switch 13 and the emergency switch 14 to induce radio waves to the IC U3.

The operation status indicator (LED) of the alarm main body 2 is turned on by the operation of the IC U3 and resistance is generated by connecting to GND connected to the handbag through a jack and a plug connected to the sensor 17, and the output is stopped. The alarm goes into standby.

In such a state, if a criminal steals the entire handbag and runs away, or if the main object in the handbag is stolen by opening or closing the handbag, or cutting the middle of the line connected to the detection sensor 17, or the detection sensor 17 ), The piezoelectric buzzer 10 of the burglar alarm 1 notifies the high alarm sound when the plug or the like which connects the main body 2 to the main body 2 is notified from the main body 2. And, to be able to obtain the anti-theft effect by arresting the theft at the scene, the operation of the burglar alarm (1) in the case of theft by opening the door between the opening and closing of the handbag 20 primarily; The sensor 17 connected to the plug tweeter 11 'of the main body 2 is embedded between the opening and closing of the handbag 20 so that the resistance is released at the moment of opening the opening and closing period so that the power is led to the amplifiers Q3, Q4 and Q5. When the piezoelectric buzzer 10 outputs a high alarm sound to notify the handbag holder and the surrounding forests of theft, when the stolen person snatches the handbag, the emergency switch 14 is turned on. When 2) and the transmitter 3 maintain a certain distance, the alarm sound does not occur, but when the distance exceeds a certain distance, the resistance is extinguished and the alarm sound is emitted. The operation of the emergency switch 14 causes the amplifier Q8. At the IC U4, the piezoelectric buzzer 10 emits a high-alarm sound through the amplifiers Q5, Q6 and Q7.

When applying the burglar alarm (1) of the present invention to a wallet or the like, the panel (18) is built into the card case of the wallet to carry the wallet, and the body (2) is worn by using the creep (12) on the waistband. If the stolen person takes over the wallet while operating in the buy state, the panel 18 is separated from the main body 2, so the resistance is also released and the power is guided to the amplifiers Q3, Q4 and Q5. 10) outputs a high alarm sound to notify the handbag holder and the surrounding people of theft, the alarm operation of the main body (2) does not necessarily seize the handbag or purse, even if shearing the connecting line that is not the case of opening By the same action as the piezoelectric buzzer 10 of the main body 2 is to generate an alarm sound.

In addition, the present invention can also be used as an anti-lost alarm. In this case, the alarm body (2) of the present invention is worn on the appropriate part of the infant's clothing, and the parents carry the transmitter (3) and the infant has a large crowd. If the emergency switch 14 is turned ON when it is not visible, the piezoelectric buzzer 10 emits a high alarm sound through the amplifiers Q5, Q6, and Q7 through the amplifier Q8 to the IC U4. The location of the infant can be confirmed within a short distance, thereby preventing the occurrence of childbirth.

As described in detail above, the burglar alarm (1) of the present invention can be installed without having to occupy a large space in various handbags by compacting its volume, thereby providing convenience in practical use, and inadvertently such as handbags and purses. It is equipped with a main body (2) capable of emitting a high-altitude alarm and a transmitter (3) for controlling its operation as a password. It is possible to establish a cheerful social law order by preventing, and it is a useful design that the expected effect is unexpectedly great, such as to carry the main body to infants to prevent the lost child.

In the following appended claims for utility model registration will be disclosed a technique that will be protected in the present invention, it is extremely easy by those skilled in the art, such as replacing some constituent members with equivalents, or changing the shape and material Modified embodiments that can be implemented will also be called the same technology as the present invention.
