Description

This utility model relates to alarm systems for unauthorized opening of pockets of clothing, compartments of bags, briefcases, backpacks, suitcases and other products.

Closest to the claimed technical solution is a signal device (RU 2045096, publ. 09/27/1995), which contains an audio signal generator, the power source of which is connected in series with the circuit closure node from the chain tension, including a bracket with a slot for the chain hook, which serves as the first electric the contact of the circuit node, and the second electrical contact, made in the form of a flat spring, mounted on the base of the device under the bracket opposite the hole in the bracket for introducing the chain hook and located at an angle to the bracket, a mode switch, a magnetically opening contact and a magnet, and the movable contact of the mode switch is connected to the power supply terminal, the closing contact of the mode switch with the power bus through the circuit closure unit from the chain tension, the opening contact of the mode switch with the power bus through the magnetically controlled contact located on the side of the door, the magnet is located in the recess of the jamb opposite the magnetically controlled contact, the slot in the bracket and the flat spring are symmetrical E relative to the opening in the bracket. However, this technical solution was used to give an alarm in case of unauthorized opening of the doors of residential and office premises.

The task to which the claimed utility model is directed is to create an alarm device for unauthorized opening of a pocket with high functional reliability and advanced functionality.

This problem is solved due to the fact that the claimed device for unauthorized opening of the pocket consists of a power source, an audio signal generator integrated into the sound emitter, a circuit closure unit, characterized in that it contains a circuit breaker unit including a resistor, a transistor switch, while Any metal haberdashery fittings that can be closed are used as a circuit closure node and a circuit breaker, electrical conductors are connected to the sides, Addi ctive circuit is connected between the base and emitter of transistor circuit opening unit supplies power to the key, wherein the circuit assembly is in the protected pocket, and circuit breaking device node and the remaining nodes is inside a user's clothing.

The technical result provided by the above set of features is the ease of use of the device.

Currently, when sewing outerwear, bags, briefcases, backpacks, suitcases and other products, various haberdashery accessories are used. Some types of accessories are made of electrically conductive material, in particular haberdashery buttons. The haberdashery button consists of two parts, each of which is fixed on different details of clothes and fixed among themselves. When the button is closed, both its parts are tightly pressed, due to which they have low electrical resistance. When the button is undone, the resistance between its parts is large. This utility model is based on the use of this property.

Unauthorized opening of a pocket means penetration of third parties into a pocket of clothes, separation of bags, briefcases, suitcases and other products.

The essence of the utility model is illustrated by a figure, which depicts one of the simplest electrical circuits, according to which the algorithm of the device for signaling an unauthorized opening of a pocket is implemented.

The electrical circuit of the device consists of a power source 1, two haberdashery buttons - circuit closure unit 3 and circuit breaker 2, resistor 4, transistor 5 and sound emitter 6.

The circuit is a simple transistor switch assembled on a transistor 5, the collector circuit of which includes a sound emitter 6. Button - circuit closure node 3 is connected between the base and emitter of transistor 5. Button - circuit breaker node 2 supplies power to the key. If power is not supplied, then button 2 is open, then for any state of button 3 on the sound emitter 6 there is no voltage and, accordingly, there is no acoustic signal. If button 2 and button 3 are closed, then the transistor 5 is closed, that is, the voltage on the base is zero relative to the emitter due to the closed button 3, and there is no voltage on the sound emitter 6. When the button 3 is opened, the base of the transistor 5, due to the presence of the resistor 4, is supplied with positive voltage, the transistor 5 is opened, voltage is applied to the sound emitter 6 and an acoustic signal sounds.

As a haberdashery metal button, any metal haberdashery accessories that can be closed can be used.

The device operates as follows.

The protected pocket is closed with a haberdashery metal button 3, which is used as a tamper sensor. Electrical conductors from a small electronic device located somewhere in clothes are connected to different parts of the button. Another haberdashery button 2 of the same design is connected to the same device, performing the function of disabling the alarm, located in a convenient place for the user in clothes. When the protected pocket is opened, button 3 opens, the circuit of this button opens and the electronic device operates depending on the state of button 2. If button 2 is closed, that is, the chain of button 2 is closed, then when button 3 is opened, and therefore the pocket is activated, the electronic device and the acoustic alarm will turn on. If button 2 is open, that is, the circuit of button 2 is open, then when you open button 3, and therefore the pocket, the electronic device will not turn on the acoustic alarm. Thus, to open the pocket yourself, you must first open button 2.

Such a device can protect against unauthorized opening as well the separation of bags, briefcases, suitcases.
