Locking Mechaiism.

The invention relates to the field of security devices with an alarm system that allows you to determine the moment of breaking the locking devices.

Known locking mechanism according to Russian patent 2053561 C1, 01/27/1996, including a locking device with a deadbolt and a sensor for detecting unauthorized opening of the mechanism. The sensor is made responsive to vibration during unauthorized opening of the locking device.

The disadvantage of this device is its not high strength, which allows it to be easily cracked and even taking into account the triggering of the alarm sensor, it is possible to perform malicious acts, as well as the fact that the vibration sensor can respond to non-illegal actions - such as: repair in a building, traffic etc., there can be many situations, as a result of which false positives will occur. This can be used by intruders who, when triggering an alarm several times in a row, without visible external deformations of the locking mechanism, will force either the owner or the guard to turn off the alarm due to its “malfunction and use it.

The objective of this utility model is to create such a locking mechanism that would be devoid of the above disadvantages.

This technical result is achieved by the fact that in the locking mechanism, including a locking device with a deadbolt and a sensor for detecting unauthorized opening of the mechanism, there is a protective element located on the outside of the lockable leaf and completely closing the locking device, and the sensor is placed so that it does not go beyond the protective element and is configured to respond to changes in its spatial parameters and to direct contact with it.

This implementation of the proposed mechanism allows you to simultaneously strengthen the design of the locking devices, for example, through the use of armored plates located on the outside of the door, and the alarm will not allow itself to be determined until the sensor acts directly on the sensor or if the position of the sensor changes due to an attempt to act on protective element.

The utility model is illustrated in more detail by the drawing.

The locking mechanism 1 includes a sensor 2 for detecting unauthorized opening of the mechanism. From the outside of the locked room there is a protective element 3 located and fixed on the outside of the lockable sash 4 and completely closing the locking device 5 with a bolt (not shown). The protective element 3 can be made in the form of a hardened steel plate, from a composite material or from any currently known high-strength material. The sensor 2 is placed strictly behind the protective element on the side of the sash 4, without going beyond its overall dimensions. Sensor 2 can be made with

/ s the ability to respond to changes in its spatial

parameters and direct contact with him.

Using a locking device.

Under normal conditions, the locking device works like a regular lock for a door, window, etc.

When trying to unauthorizedly open the locking mechanism, the attacker will encounter the first problem, namely, overcoming the protective element, for which he will need special tools. Since the protective element is made of high-strength material, for its breaking it is necessary to apply sufficiently large power loads, which will lead to deformation of the sensor, or to a change in its spatial position, or to its possible fracture - that is, to a change in its spatial parameters. This will allow you to accurately determine that the locking mechanism is opened by intruders, and self-operation did not occur due to the above reasons. The same thing happens if the attacker does not just try to break the protective element, but tries to drill a hole to gain access to the locking device 5. And in this case, the sensor reacting to direct contact with the drill, or other penetrating tool, or even with a sheaf of gas burners, it will turn on signaling devices and illegal entry into a locked room will be prevented.

The implementation of the locking mechanism in this form will seriously increase its strength and protective qualities, as it has a double degree of protection, and the second level of protection can only be determined at the beginning of overcoming the first stage - the protective element, because It will not be possible to determine in advance whether an alarm will occur, since the sensor will not be triggered by vibration, tapping, etc. It's for

attackers will be a factor of complete surprise in connection with which unwanted penetration will be almost completely prevented.

However, at the request of the customer, the sensor in the locking mechanism can also be located outside the protective element. In this case, when you try to break the lock by mechanical means, the sensor will first of all suffer and notify that malicious actions are being performed.
