Abstract

An electromechanical device for blocking vertical rods of a door lock, comprising a housing, characterized in that the housing is configured to be mounted on the outer upper or lower part of the door lock housing, wherein a movable locking system and a locking bolt interacting with it are arranged in the housing of the device and can be extended from the case for blocking the vertical rods of the door lock.

Description

The proposed utility model relates to motor electromechanical locking devices designed to block one of the vertical rods of the door bolts (in particular, the mechanical) lock in the locked position (with the lock bolts fully extended).

Electromechanical lock traction locks are used to increase the resistance of conventional 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 closest analogue to the proposed utility model is the electronic motor blocker MOTTURA 49.110, (http://web.archive.org/web/20120204120212/http://door.ru/c_mmcode.php, 04/04/2012). The disadvantage of this solution is that its installation is quite complicated. This lock is installed in the gap with one of the vertical rods of the crossbar. For its installation, it is necessary to provide in advance a place for fastening the lock housing, so that the lock rods are aligned with the vertical lock bolts of the lock itself.

The problem to which the proposed utility model is aimed is to increase the security against unauthorized opening of almost any already installed mechanical lock equipped with vertical rods.

The technical result, which manifests itself in solving the problem, is expressed in the simplification of equipping mechanical locks with modern electronic access restriction systems and is achieved by the fact that the electromechanical device for blocking the vertical locks of the door lock contains a housing configured to be installed on the outer upper or lower part of the door lock housing, moreover, a movable locking system and a locking bolt interacting with it are arranged in the housing of the device; extension from the housing to block the vertical rods of the door lock.

Further, the proposed utility model is illustrated by drawings:

In FIG. 5-7, the device is shown with the engine and worm removed.

An electromechanical device for blocking vertical rods (1) of a door lock (2) comprises a housing (3) configured to be installed on the outer upper (4) or lower (5) part of the door lock housing (2). In the housing (3) there is a movable locking system and a locking bolt (6) interacting with it, made with the possibility of extension from the housing (3) to block the vertical rods (1) of the door lock. The device is attached to the door lock case (2) with two screws through the holes (7) and (7 ') made in the case (3). The mounting hole (7 ') is made for a screw with a head in the “patay” and is located on the end of the housing (3) from the side of the vertical rod (1).

The movable locking system consists of a direct current motor (8) with a gearbox, a rack and pinion transmission (worm (9) and a rack (10) with an oblique tooth) combined with a pusher (11) of the locking bolt (6) and the locking bolt locking system in extreme ("locked") position and two springs (12), (13) located at the ends of the rack-and-pinion gear, combined with the pusher of the locking bolt. The movable elements are cast by Caprolon (or other polyamides).

The hole (7) is made in the protrusion restricting the movement of the pusher (11).

A low-voltage (from 3 V to 12 V, depending on the control system) DC motor with gearbox can serve as a drive. Low power consumption of 50-150 mA, at the time of activation of the device for a period of 500 ms. up to 1000 ms., allows you to use the proposed device as a fully autonomous device with battery power, long life.

In the lower part of the device case there are guides (14) along which the pusher (11) moves. Their shape (Fig. 8) is such that when moving backward, the pusher locking mechanism (15) is compressed and remains in a spring-loaded state, because the guide (14) of the lower part of the housing (3) interferes with uncleaning.

An opening (17) is made in the device body for the engine control wire.

The device operates as follows.

If the locking mechanism of the device is activated at the moment when the door lock is open and the locking bolt has nowhere to move (Fig. 1), the locking bolt continues to remain in the device body in a spring-loaded state and is ready to block the door lock rod as soon as the door lock closes two turns of the key (at one turn of the key, locking is not performed (Fig. 2). Thus, when closing the lock on which the proposed device is installed, the vertical lock rod (1) extends (making room for the locking bolt), etc. the bolt (13) pushes the locking bolt out of the housing (3) (Fig. 7), and the locking mechanism of the locking bolt is activated, which prevents the mechanical release of the locking bolt, which does not allow the manual release of the locking bolt and release the locked vertical lock rod. Deactivating the device, the engine (motor drive) pulls the locking bolt inside the device housing, releasing the vertical lock traction for downward movement (Fig. one).

The motor is controlled by short DC pulses (from 0.5 sec. To 1 sec.) Of different polarity to change the direction of movement of the rotor. The impulse should not be less than the time required to move the rail from the initial position to the final and vice versa. The pulse time can be much longer than that necessary for the final movement of the rail, because with further rotation of the engine rotor, the rail disengages from the worm. In this case, the spring (12) is in a compressed state, which allows for gear engagement when changing the direction of rotation of the engine rotor. The same is true for the other extreme position of the rack and pinion transmission (Fig. 7).

In FIG. 5 shows a diagram of the device in the unlocked position, the locking bolt (6) is retracted into the housing (3) of the device. The locking bolt (6) is retracted into the housing (3) by the protrusions (16).

In FIG. 6 is a diagram of the device in the “cocked” position, when the pusher (11) of the locking bolt (6) is in the extreme extended position, and the locking bolt (6) itself remains in the housing (3), because open vertical thrust (1) of the lock prevents its extension.

When moving forward, if nothing prevents the locking bolt (6), the locking mechanism (15) opens up (sliding along the guide) and falls into the groove of the locking bolt, fixing the locking bolt (6) in the extended state.

The locking mechanism (15) is activated by combining two grooves located in the lower part of the locking bolt and on the guide (14) of the pusher of the locking bolt. This occurs when the locking bolt is fully extended.

When moving forward, when the vertical lock rod (1) prevents the locking bolt (6) from moving forward, the pusher (11) nevertheless moves forward compressing the spring (13). In this case, the guides (14) do not interfere with the locking mechanism (15), but the wall of the locking bolt (6) interferes with the release, due to the absence of a groove in that place. As soon as the locking bolt (6) extends, the groove in the locking bolt will be at the level of the protrusion (16), which "pops" into this groove.

In the case when the locking bolt is in the cocked state (Fig. 6), i.e. when the two above-mentioned grooves are not aligned, the locking mechanism is in a compressed state and does not impede the movement of the locking bolt (compression of the locking mechanism is carried out either due to the elasticity of the material from which it is made (caprolon), or due to a revolving spring placed from the bottom of the locking mechanism) . When you try to squeeze the locking bolt (abnormal mode) in the case when it is in the fully extended state, the bolt rests on the pusher stopper and in order to move the locking bolt you need to make considerable effort to turn the worm gear. In the case of a regular operation of the device mechanism, the pusher of the locking bolt moving along the guides releases the locking mechanism from the groove and pulls the locking bolt back.

It is advisable to carry out the most effective management of the proposed device using the Easy Install DK-2W controller (utility model patent No. 123437) with an integrated EXIT button and optimal characteristics for installation on metal entrance doors, available on the website http: //www.electroniko. com / dk-2w.html.

The optimal technical result is achieved when using this lock together with the Easy Install DK-2W controller (patent for utility model No. 123437), because This controller as well as the proposed device is installed in the immediate vicinity of the mechanical lock and fully meets the necessary characteristics.

The device proposed according to the utility model avoids the need to install limit switches for the extreme position of the pusher of the locking bolt, which in turn can significantly increase the reliability of the structure.
