Description

The proposed group of utility models relates to electromechanical locking devices designed to block the main bolt or the vertical rods of lever mechanical locks.

Electromechanical locks are used to increase the resistance of conventional lever mechanical locks to the actions of attackers using both mechanical master keys based on various principles and forceful methods of influence. Management of such devices is carried out using various modern access control systems, consisting, as a rule, of an RFID reader of contactless identifiers, a controller for controlling electromechanical locks and related system elements.

The famous Mottura castle of the 52 series (http://web.archive.org/web/20090619220255/_52.html, 06/19/2009).

The disadvantage of this castle, as well as its analogous ones, is its weak security against the possibility of manipulating with levers.

The task to which the proposed group of utility models is directed is to increase the security against unauthorized opening of virtually any heavy lever mechanical locks, as well as the possibility of retrofitting already installed and used locks.

The technical result achieved by the proposed group of utility models is to increase the protection of the level lock from unauthorized access.

The technical result is achieved by the fact that, according to the first embodiment, the electromechanical device for blocking the main bolt or vertical rods of the level lock contains a movable locking system and a locking bolt interacting with it, connected with the main bolt or vertical rods of the level lock and configured to block their movement, the first sensor , which controls the displacement of the lever plates of the lock, the second sensor, which controls the displacement of the main crossbar or vertical rods of the lever a lock, a control controller associated with the sensors, and a power source, the movable locking system and the locking bolt interacting with it are placed in a housing configured to install a level lock in the housing.

The technical result is also achieved by the fact that according to the second embodiment, the electromechanical device for blocking the main bolt or vertical rods of a level lock contains a movable locking system and a locking bolt interacting with it, connected to the main bolt or vertical rods of a level lock and configured to block their movement, the controller control, power source, protective element made of a layer of flexible insulating material and a layer of conductive material connected annogo with control by the controller, wherein the protective element is configured to mount to the surface, preventing access to the lock, and the laminated label closed, the movable locking system and interact with the locking latch has a housing adapted to be mounted in the lock case for lever.

The flexible insulating material is textolite or getinax, and the conductive material is metal foil.

The protective element is made with the possibility of mounting on the outer surface of the lock housing or on the door leaf or on the lock pocket.

The protective element is fixed by means of double-sided tape.

A layer of conductive material is connected to the spring contact control controller or the wire through the connector.

FIG. 1 - the housing of the electromechanical device in which the locking system and the locking bolt interacting with it are located;

FIG. 2 - the housing of the electromechanical device in which the locking system and the locking bolt interacting with it are located (the housing cover is removed);

FIG. 3 - locking system and the locking bolt interacting with it.

The principle of operation of the proposed electromechanical device is based on a temporary restriction on the identification of the authenticity of a mechanical key and excludes any methods of breaking a mechanical level lock applicable to its secret part (master keys, self-impression method, etc.).

In fact, a mechanical key is the same information carrier as an electronic key (card), with the only difference being that it is impossible to select an electronic key by enumerating bits of information recorded on it. The electronic key is read entirely in a very short period of time and is either accepted or rejected by the controller.

The lever mechanism of the lock, being, in fact, the same reader (but mechanical) of the information recorded on the key, allows code enumeration by manipulating directly with the lock levers and is not time-limited.

The first sensor controls the displacement of any of the lever plates of the lock secrecy mechanism. The second sensor monitors the displacement of the main bolt or the vertical lock rod. Motion sensors, optical or end sensors can be used.

An electromechanical device has the ability to block the movement of the main bolt or vertical rod in one or more positions, depending on the model of the mechanical lock.

At rest, the electromechanical device does not consume electricity and is in the unlocked state. When the key is moved for the first time, the first sensor is triggered. The control controller starts a timer set for approximately 500 milliseconds (500 milliseconds is the time sufficient to rotate the standard key in the lock 180 °, which corresponds to one revolution of the key in the lock). If during this time the main deadbolt or vertical rod is displaced, then the second sensor will work. The control controller recognizes this key as valid and turns off, because only a valid key can open the lock for one turn of the key in 500 ms. The time interval can be changed when adapting to a specific lock mechanism. If during this time the main deadbolt or vertical rod does not move, then the second sensor will not work, the key will be invalidated and the electromechanical device will go into the “locked” state and will remain in this state until the first sensor is triggered, i.e. until the key is returned to its original state or removed from the keyhole.

In the locked state, the control controller does not turn off, but switches to the limited power consumption mode (units of microamps) and monitors the status of the power source and sensors. In this state, even on a half-discharged power source, the device can remain for several years. In the event of a critical discharge of the power source, the electromechanical device will enter the “unlocked” state.

In the case of repeated attempts to open the lock (when the electromechanical device is triggered) during one cycle (cycle is the time sufficient to completely open the lock), the lock is blocked for a certain time interval set in the control controller. If the opening attempts do not stop, then the blocking time is resumed each time, but no more than the time set by the controller.

The control controller can be equipped with an “alarm output” connected to an external security system (security control panel, GSM alarm, video surveillance, etc.).

Depending on the purpose of the lock, software filters can be installed in the program of the device control controller, which are responsible for recognizing conflicts and making decisions (for example, “shaking hands” - when a user with a valid key, for one reason or another, couldn’t open the first time lock, then an additional attempt is given and the timer time is increased; attempted hacking and, accordingly, locking the lock for a specified period of time; alarm message; “forced entry” function is informed e to the control of the opening of the lock under duress).

Also, the device’s self-adaptation program for a specific user (for example, an adaptive gearbox in a car) can be written to the control controller, decreasing or increasing the interval of the timer, thereby imposing more stringent or soft requirements on the process of opening the lock. The latter may be important for people with Parkinson's disease.

More stringent requirements for the process of opening the lock can be applied if the lock is installed in the doors protecting values or valuable information (banks, safes).

Moreover, electronic authentication of a mechanical key is carried out at each turn of the key, both when opening the lock and when closing it. This may be important because everyone knows the fact that a mechanical lock tends to wear out, gradually the key begins to “bite” and as a result, such a lock can still be difficult to close, but it is no longer possible to open it. A lock equipped with an electromechanical device simply will not make it possible to close such a lock by contacting a service center. A lock equipped with this device virtually eliminates the possibility of unauthorized opening of the lock without the use of high-precision duplicate keys or the destruction of functional elements of the system.

In FIG. 1-3 shows the housing of an electromechanical device in which the locking system and the locking bolt interacting with it are located. The movable locking system consists of an electric motor (1) with an eccentric (2) worn on the axis, a spring (3), a locking ball (4), which is pressed by the spring (3) to half its diameter into the recesses in the locking bolt (5) of the device , thereby blocking the locking bolt (5) in one of the positions, and accordingly blocking the main bolt or the vertical lock rods. In the unlocked state, the eccentric (2) rotates with its maximum diameter in the direction of the locking ball (4), squeezing it out of the recess in the locking bolt (5), while the spring (3) is compressed, pushing the locking ball (4) in the opposite direction. In the locked state, the eccentric (2), on the contrary, rotates with its minimum diameter to the locking ball (moves away from it), thereby giving the locking ball (4) the opportunity to enter half of its diameter (under the action of the spring) into the recess of the locking bolt (5), blocking the main crossbar or vertical draft of the lock.

The device is installed in the lock housing coaxially with the movement of the bolt or vertical lock rods. Fastens to the lock case in free space by means of screws with a threaded connection or rivets.

The locking bolt is connected to the bolt of the lock or vertical rods directly or through the bracket (depending on the modification of the lock and its layout) by means of threaded screws or rivets. In the unlocked state, the lock bolt or vertical rods move freely with the locking bolt of the device.

Since the device proposed according to the first embodiment blocks the movable parts of the lock, it remains possible to disable (before attempting to open the lock) the device itself. In this case, the lock will remain unprotected for these devices. To prevent the very possibility of such a development of events, a device is proposed according to the second embodiment, which has built-in protection for the safety of its own structural elements and the main components of the castle from mechanical stresses, such as drilling.

The protective element is mounted on a surface that prevents access to the lock (on the outer surface of the lock case or on the door leaf or on the lock “armor” pocket), and is made of a layer of flexible insulating material and a layer of conductive material, for example: of foil flexible textolite or getinaks ( a few microns thick) connected to the control controller by means of a spring contact or a wire through a connector (in case of fastening to a lock “armored” pocket).

When installing the lock cover (in the case of mounting the protective element on the outer surface of the lock case), the contact area of the protective element comes into contact with the spring, which is the contact of the device controller. Foil textolite is attached to the front cover of the lock by means of double-sided tape or otherwise, with the foil facing out. Externally, it is closed with a decorative laminated sticker that protects the foil from accidental contact with the metal elements of the door.

The essence of the defense is as follows.

When trying to drill the lock case, in order to destroy the electromechanical device or the functional elements of the lock, the drill closes through itself a protective foil layer of a sticker on the lock case, which will lead to the immediate operation of the device and blocking of the lock itself. Further destruction of the main blocking elements no longer makes sense, because the lock will remain locked for a long period of time or permanently, depending on the conditions entered into the control controller program. In case of operation of the device, drilling the crossbar strut also does not make sense.
