Description

The invention relates to the field of protection of objects against access by unauthorized persons, in particular to adapters for mechanical locks.

Currently, electronic locking devices (RF patent No. 112244, January 10, 2012, China patent No. 204960553, 01/13/2016), electromechanical locks (RF patent No. 157225, 11/27/2015) and other types of locks with automatic shutter release, which allow for a higher level of room security by eliminating the larva with keyhole from the design of the lock, characteristic of mechanical lock designs, and using digital keys as a means of identification. A keyhole can be subject to vandalism, as it is visible and easily accessible from the outside of the room. However, new types of locks are finished products, which often have a high cost, not always available to users. Also, the blocks that ensure the functioning of such constructions of locks suggest their location at a distance from each other, which requires a search for a separate place for them and is inconvenient to use. In addition, the installation of such locks involves a whole range of works to remove the old lock, installing a new one, which may require a seat in a door of a different size, while connecting all electronic parts and wires may require additional complex installation work, which indicates high complexity of known solutions.

In order to reduce the cost of the work carried out, it is possible to use adapters that allow you to upgrade an already installed lock, or immediately install a low-cost lock and convert it to an electromechanical one when making a door.

A known device design for electromechanical, electromagnetic, motor locks, adopted as the closest analogue to the claimed solution, containing a reader and a controller for controlling locks (RF patent No. 123437, 12/27/2012), while the reader is made in a case that is a decorative an overlay for a cylinder cylinder larva or keyhole of a level lock, and is arranged to be installed directly on the door leaf from its outer side, and it is arranged to transmit a key code and the controller for controlling electromagnetic, electromechanical and motor locks, and the controller for controlling electromagnetic, electromechanical and motor locks is made in the housing, which is a decorative overlay on the cylinder cylinder lock or keyhole of the level lock, contains an exit button integrated into the housing, made the ability to install directly on the door leaf from the inside, and it is made interacting with the above key reader with radio astotnoy identification. The reader may be an RFID key reader. The controller for controlling electromechanical, electromagnetic, motor locks can also work with Touch Memory keys and with RFID cards / key fobs of various formats.

The implementation of the reader in the form of a decorative lining located on the outside of the door and closing the keyhole allows you to protect it from manifestations of acts of vandalism. The execution of the controller in the form of a decorative lining on the lock cylinder from the inside of the room with the “exit” button or the ability to work with Touch Memory keys and with RFID cards / key fobs allows you to control the lock only electronically and get a “invisible” lock, which is especially important for objects , the protection of which requires increased attention. The plus is that the reader and controller allow you to manage different types of locks and do not require installation work, including drilling and wall shredding for their installation due to the location of the reader and controller directly in the area of the door lock.

However, installing the specified reader and controller to obtain a fully automated lock involves a significant amount of work to dismantle parts of the existing lock, for example, removing the lock larva with a keyhole and then mounting the electronic parts - connecting the actuator to the bolts that lock and unlock the door. In this case, it is necessary to accurately connect all the wires and components to avoid improper installation, which can subsequently lead to malfunctions of the lock, jamming of the door and the inability to get into the room or be locked in it. Therefore, it is more advisable to order the installation of such a reader and controller immediately at the door manufacturer, as described in the description of the patent of the Russian Federation No. 123437. The use of electronic keys for both opening and closing the lock leads to the need for a constant vigilant attitude to where it is located, since if it is lost or damaged, it will also be impossible to get into or out of the room. The problem of mindfulness is especially relevant for children, who are often scattered. Thus, the known device has a high complexity and complexity of installing the device to ensure the smooth operation of the "upgraded" lock.

The objective of the invention is the creation of an electromechanical adapter that allows you to upgrade the installed mechanical lock and increase the convenience of its installation at home.

The technical result of the invention is to reduce the complexity of installing an electromechanical adapter to modernize a mechanical lock, ensuring its reliable operation by directly connecting the actuator to a mechanical lock device acting on the mechanism that moves the bolts of the mechanical lock to unlock and lock the door.

The technical result is achieved by using an electromechanical adapter for a mechanical lock, comprising a device for receiving and transmitting a signal for unlocking and locking a door with a power supply installed on the door leaf, an actuator that converts electrical energy into mechanical energy and is connected to the specified device for receiving and transmitting a signal and a mechanical lock device acting on the mechanism moving the bolts of the mechanical lock for unlocking and locking the door.

As a device of a mechanical lock acting on a mechanism that moves the crossbars of a mechanical lock to unlock and lock the door, a key from a mechanical lock or a pinwheel of the inside of the larva with a keyhole from a mechanical lock can be used (http://mezhdveri.ru/17445-lichinka- dlya-zamka.html).

Due to the connection of the actuator with the mechanical lock device, it is not necessary to dismantle the parts of the mechanical lock, for example, the larvae with the keyhole, which organize the lock, including the closest analogue, according to the scheme: sensor - controller - actuator with drive - a mechanism that moves the lock bolts to lock and unlock the door. The installed mechanical lock is stored unchanged, and the original key to it or a pinwheel of the inside of the larva with the keyhole from the mechanical lock is rigidly fixed to the adapter actuator. The claimed solution allows to realize the work of the obtained lock according to the scheme: a device for receiving a signal for unlocking and locking the door - an actuator with a drive - a mechanical lock device - a mechanism that moves the lock bolts for locking and unlocking the door.

An advantage of the proposed solution is that the installation of an electromechanical adapter is possible on almost any mechanical lock. In this case, no replacement of the installed mechanical lock or its parts is required - the adapter is easily installed at home and at any time, if desired, can be removed from the door with the return of the previous scheme of a conventional mechanical lock. Using an adapter can significantly reduce the complexity of installing an electromechanical lock and provide modern protection against unauthorized access and acts of vandalism from the outside of the door. In this case, the inside of the door can be closed and opened using electrical signals that trigger the mechanical lock device (specified key or pinwheel), as well as in the usual way to open the door manually when turning the key.

In one embodiment, the device for receiving and transmitting a signal for unlocking and locking the door may be a GSM modem with a controller located in the area of the lock and which, upon receipt of an SMS message / code from the user's mobile phone, sends a signal to the actuator for unlocking and locking the door.

In another embodiment, a device for receiving and transmitting a signal for unlocking and locking a door may be a sensor mounted on the door leaf from its outer side, and a controller mounted on the door leaf from its inner side. The sensor may be an RFID key reader or any other variant of electronic keys.

The electromechanical adapter may also include an anti-vandal pad that closes the keyhole on the outside of the door. The anti-vandal pad can be combined on the same plate with the sensor or located separately next to it.

The actuator can be implemented by known technical solutions that allow you to implement a drive that converts electrical energy into mechanical energy. The main point is that the actuator must act directly on the mechanical lock device (specified key or turntable) to unlock and lock the door.

Also, well-known components are used to install an electromechanical adapter, which can be purchased at a low price in a store and assembled, which eliminates the need to purchase a ready-made expensive electronic or electromechanical lock.

In FIG. 1 shows the design of an electromechanical adapter with an actuator comprising gears and an electric motor; FIG. 2 shows a design of an electromechanical adapter with an actuator comprising an electromechanical drive; FIG. 3 shows a door from the outside with an installed electromechanical adapter; FIG. 4 - a side door with an installed electromechanical adapter, FIG. 5 - a door from the inside with an installed electromechanical adapter.

In one embodiment, the electromechanical adapter for a mechanical lock comprises a device for receiving and transmitting a signal for unlocking and locking the door, including a sensor 1 mounted on the door leaf 2 from its outer side in the region of the mechanical lock 3, and a controller 4 with a power supply 5, mounted on the door leaf 2 from its inner side in the area of the mechanical lock 3, and also contains an actuator 6 that converts electrical energy into mechanical energy and connected to the specified controller 4 and key 7 from the mechanical lock 3 for unlocking and locking the mechanical door (Fig. 3, 4, 5).

The actuator 6 may include an electric motor 8 connected to the drive gear 9, transmitting torque to the driven gear 10, which is connected to the larva 11 of the mechanical lock 3, into which a key 7 is inserted to unlock and lock the bolts of the mechanical door lock 3 (Fig. 1). Also, the actuator 6 may include a toroidal motor 12 connected to the larva 11 of the mechanical lock 3, into which a key 7 is inserted to unlock and lock the bolts of the mechanical door lock 3 (Fig. 2).

The electromechanical adapter may include an anti-vandal pad 13, which externally closes the keyhole of the mechanical lock 3.

Also, the inventive adapter may include a screen with touch control 14 for setting commands and programming the controller 4.

The operation of the mechanical lock 3 with the adapter installed is as follows.

When the RFID card is applied to the sensor 1 located on the outside of the door (or upon receipt of the key via any other channel), the controller 4 activates the actuator 6 by its signal, which turns the key 7 and thereby unlocks or locks the bolts of the mechanical lock 3 From the inside, the door can be opened or closed manually by turning the key 7. Also, open and close the door from the inside by pressing the “exit” button, which can be installed on the inner door leaf in the area of the mechanical lock 3, as was the case the closest analogue.

In addition, with an embodiment of a device for receiving and transmitting a signal for unlocking and locking a door using a GSM modem (not shown) and controller 4, it is possible to send an SMS message / code from a mobile phone, through which an electrical signal from controller 4 will be transmitted to actuator 6 and on to key 7.

Also, locking and unlocking of the door can occur due to the rigid connection of the actuator with the drive with the pinwheel of the inner part of the larva of a mechanical lock (not shown).

The installation of an electromechanical adapter on a mechanical lock for one embodiment may occur as follows.

The decorative pad of the lock is unscrewed from the inside of the door, a controller 4 is installed at this place. To use the sensor 1, a door is drilled (to output signal wires to the outside of the door), the key 7 is rigidly fixed in the kinematic part of the adapter mechanism (actuator 6), the key is inserted 7 into the keyhole, the larvae of the mechanical lock 3. On the outside of the door, install the sensor 1. Next, unscrew the decorative trim from the outside of the door and install the anti-vandal trim 13, which can be l equipped with sensors for removal. Then install the power supply 5 (batteries) for the controller 4, program it on certain keys. If required, carry out additional programming to enable options (setting up additional communication channels, communication with the user's personal account, etc.).

During operation, the controller 4 provides warning information about the discharge of the batteries 5. In the presence of such signals, the user needs to replace the battery 5.

Using the inventive adapter allows you to get an electromechanical lock without changing the standard lock while reducing the cost of all work, to exclude complex installation work to change the size of the seat, which occurs when changing one type of lock to another, to provide the possibility of obtaining a more reliable lock at home without removing the door and contacting the manufacturer. At the same time, the electromechanical adapter allows you to expand the security and controllability of existing mechanical locks of any type to the level offered by modern electromechanical locks.
