RU180287U1 - ELECTROMECHANICAL LOCK MORTGAGE SUVALD LOCK - Google Patents

Abstract

The utility model relates to the field of construction, namely to locks, locking and unlocking locks and other locking devices using mechanical or electromechanical means. The technical result is the provision of increased protection of the castle from unauthorized access. For this, an electromechanical device for blocking the secrecy mechanism of a level lock contains a set of locking level plates with special grooves and a locking plate interacting with them, made with the possibility of blocking their movement, a first sensor monitoring the vertical displacement of the level lock plates, a second sensor controlling the movement of the main lock beam lock, control controller associated with sensors, and power supply. The locking system is universal for heavy level locks, which allows you to integrate it into standard level locks without changing the overall dimensions or substantially reworking the internal structure of the lock. The utility model relates to electromechanical devices designed to block the secrecy mechanism and, as a consequence, the locking system (main bolt and / or vertical rods). At the same time, the locking mechanism is not a separate block, but represents a set of solutions that allow implementing this protection method directly in the design of the locking mechanism. 3 s.p. f-ly.

Description

Mortise lock mortise with electromagnetic lock.

The proposed utility model relates to locks with an electromechanical locking mechanism for secrecy of the castle. When the protection is activated, the leveling plates are blocked and further actions of the attackers become impossible.

Electromechanical locking of locks is used to increase the resistance of conventional lever mechanical locks to the actions of attackers using mechanical master keys based on various principles.

The closest analogue is an Electromechanical device for blocking the main bolt or vertical rods of a lever mechanical lock (Utility Model Patent No. 143624 U1, publication date 07/27/2014, author Maltsev Andrey Vadimovich).

This solution is similar to that proposed on the following grounds:

- the presence of built-in position sensors of the crossbar and suvald;

- blocking on the principle of a time interval from the moment of lifting the level plate to the beginning of the movement of the crossbar.

Is different:

- a way to lock the lock;

- the state of the lock in the absence of power supply.

In the case of the implementation of the solution according to patent No. 143624, the lock is locked by acting on the bolt using a separate movable locking mechanism, i.e. the blocking element is an independent structure integrated in the lock case. In a sense, in this case, a “lock in the lock” is obtained, which has positive aspects (enhanced protection) and negative (stringent requirements to the housing dimensions, reduced maintainability and increased likelihood of mechanical breakdown and / or wear, more expensive implementation of the solution due to the more complex technical design).

In the proposed embodiment, the lock is locked by locking the privacy mechanism. To do this, standard leveling plates (at least two) are being finalized and a blocking plate is installed. The locking levers have grooves on the end opposite the front plate of the lock, which, when the protection is triggered, enter the mating grooves of the locking plate. Thus, the proposed solution is a set of actions to finalize the standard lock, and not an independent mechanism for locking and is universal, because the dimensions of the lock plate allow you to install it in almost any case of a heavy level lock.

Also, in the case of the implementation of the solution according to patent No. 143624, in the event of a critical discharge of the power source, the electromechanical device will go into the “unlocked” state, which theoretically reduces protection, since if the system tries to open the lock again with a discharged power source, the protection system will not work.

In the proposed solution, in the absence of voltage in the supply network, the device remains in the position that was activated, since electricity is only necessary to ensure the movement of the blocking plate, but not to keep the specified plate in a certain position. The locking is supported by the mechanical interaction of the locking plate and the locking levers. The lock, in which the protection has already tripped and after which the power source has been discharged, remains locked until the power supply resumes, and repeated attempts to unauthorized opening will not lead to a result. After resuming power supply, the device will unlock and begin to work in a new cycle. Thus, the security of the castle is increased, because when exposed to the battery or the contacts of the electric network, the lock (if it has occurred) is not removed.

Also known are models where the protection system is based on a combination of an electromechanical locking device with a special key (for example, a mechanical lock with electromagnetic lock and access control "Fortress" (utility model No. 112930 U1, publication date 01/27/2012, Patent holder Igor V. Serikov). In this case, such solutions cannot be considered as analogues, since they are a mandatory combination of an electromechanical lock + magnetic key, and, accordingly, protection is achieved by identification the original key, and not a set of technical solutions to prevent unauthorized opening by mechanical means.

In the proposed solution, protection against tampering with master keys is implemented as follows: when the key is turned at an angle of more than 15 degrees, the pickup lift sensor is triggered, it sends a lock signal to the microcontroller. The lock delay time is 8 seconds (experimental). When using a legitimate key, this time is enough to ensure the movement of the crossbar plate and a signal to cancel the blocking when the crossbar plate with a flag passes an optical sensor built into the lock case. If the specified time limit is exceeded, the lock takes effect and the microcontroller sends a control signal (announcing with an audio signal) to the coil, which activates the trigger mechanism for blocking the suvald, leaving them in the current position.

Then the protection goes into standby mode, after a predetermined period of time (set by software from several minutes to several days / months *), a second sound signal will sound and the mechanism will return to its original position.

Technical solution

The locking mechanism is built into the lock case (Fig. 1). The mechanical part of the locking mechanism consists of two parts: leveling plates with grooves on the front side opposite the lock face of the lock (1), and a locking plate (2) with mating grooves. When the protection is triggered, the lock plate moves and locks the levers by connecting the grooves of the plate and the levers.

The principle of operation of the castle is based:

1. at the registration of the position of separately moving parts of the castle (suvald and deadbolt). The position of the levers is recorded using the first sensor (3), which is a micro switch and is triggered when lifting the levers plate. The position of the deadbolt is recorded at the time of passing the flag (4) mounted on the deadbolt plate through the second sensor (5) with optical registration of the movement of the flag.

2. data collection and analysis is carried out using a microcontroller (6), which, if appropriate conditions are met, supplies control voltage to the coils (7) installed in the lock case. Coils are connected by rods (8) with interlocking elements.

The lock protection operation in the normal mode (Fig. 2) can be divided into 3 cycles:

1. Signaling a lock to the microcontroller from the suvald position sensor when they are lifted with a key or a master key (A).

2. The standby mode (t≈8 s) of the signal from the transom position sensor (B) and the controller makes a decision. Moving the bolt in the specified time range is possible only when using a legitimate key.

3. The controller sends a signal to release the lock or to turn it on.

If the time interval between the operation of the first and second sensors is exceeded, the lock operates in the protection mode (Fig. 3). The locking plate fixes the levers with the mechanical connection of the grooves (C). Turning off the power supply does not entail removing the lock.

- The power supply of the lock is carried out from the power supply ± 12v / 4A, if the power to the lock is turned off after the protection is activated, the lock remains locked. When voltage is reapplied, the protection trips with a new cycle.

- The lock contains protection against incorrect connection of the power source.

- Locking levers were installed with grooves on the end opposite the lock face, which, when the protection is triggered, enter the mating slots of the blocking plate. At least two interlocking levers are installed in the levers package (above and below the whole package), then it is possible to install interlocking levers in any order.

- A locking plate has been installed, driven by rods in the event of a controller triggering exceeding the opening time, and.

- Suvald and crossbar motion sensors and a microcontroller connected to the coil with rods providing movement of the blocking plate are installed.

- It is possible to make a service button for emergency unlocking of the lock from the inside of the room.

- All other characteristics are similar to standard mechanical level locks.
