Abstract

A lever lock is proposed, comprising a lid with a housing inside which there is a deadbolt with a liner shank plate on which a shank stand is mounted, spring-loaded code levers with code grooves mounted on the side of the shank stand with the possibility of their movement in the transverse direction relative to the movement of the shank stand. There is at least one blocking curtain containing a curly groove interacting with the shank stand. The blocking shutter is installed with the possibility of its movement in the transverse direction relative to the movement of the shank and blocking the keyhole. At least one blocking shutter is placed between the levers, or between the levers and the bolt shank plate. 4 s.p. f-ly, 5 ill.

Description

The utility model relates to hardware and relates to locks for doors made of various materials used in residential, public and industrial buildings.

A level lock is known from the prior art that has protection against intelligent hacking methods, namely, comprising a lid with a housing inside of which there is a deadbolt with a bolt shank plate on which a shank rack is mounted, spring-loaded code levers with code grooves mounted on the shank rack side with the possibility of their movement in the transverse direction relative to the movement of the shank, at least one blocking curtain containing a curly groove interacting with the shank ka, while the blocking curtain is installed with the possibility of its movement in the transverse direction relative to the movement of the liner and the overlap of the keyhole, RU 122684.

This design of the lock has such a disadvantage as the inability to use the mechanism of additional and complete blocking of the key hole by another lock or other blocking mechanism. If you lock the key hole in the center of the lock, then access to the part of the level will remain, and only part of the level will be blocked. Thus, only partial blocking is carried out.

The technical result achieved by this utility model is to increase the security of the lock against unauthorized opening, which is ensured by the fact that since the blocking shutters are located between the levers, it becomes possible to use an additional mechanism at the edges of the levers to completely block the key hole with any other lock or lock mechanism, which can be located as in one single case with this lock, and in a separately located one, with the curtain closing the key opening It can be connected to another lock (locking device) by means of a pull rod. Structurally, this connection of the curtain with another lock can be any.

This technical result is ensured by the fact that the level lock contains a cover with a housing inside which has a deadbolt with a liner shank plate on which a shank stand is fixed, spring-loaded code levers with code grooves mounted on the side of the shank rack with the possibility of their movement in the transverse direction relative to movement shank racks, at least one blocking shade containing a figured groove interacting with the shank rack, while the blocking shade is installed is mounted with the possibility of its movement in the transverse direction relative to the movement of the liner strut and the overlap of the keyhole. At least one blocking shutter is placed between the levers, or between the levers and the bolt shank plate.

A roller is installed on the shank rack, with the possibility of rotation on the shank and interaction with the curly groove of the blocking curtain.

A roller is installed on the shank rack, the inner hole of which is square or shaped, without the possibility of rotation of the roller on the shank.

At least one additional roller is installed on the roller, interacting with the curly groove of the blocking curtain.

The utility model is illustrated by drawings on which is shown in:

figure 1 - General view of the castle, without a cover (open);

figure 2 is a side view in section;

figure 3 - General view of the castle, without a cover (closed);

4, 5 - groove with rollers.

The level lock contains a cover (1) with a housing (2), inside of which there is a deadbolt (3) with a bolt shank plate (4) on which a shank stand (5) is fixed. Spring-loaded code levers (6) with code grooves mounted on the side of the shank stand with the possibility of their movement from the key bar in the transverse direction relative to the movement of the shank stand. There is at least one blocking curtain (7). It contains a curly groove (8) interacting with the same shank stance. In the interaction of the groove (8) with the stand, the blocking shutter can move in the transverse direction relative to the movement of the shank stand and at the same time overlaps the keyhole (9). At least one blocking shutter is placed between the levers, or between the levers and the bolt shank plate. A roller (10) can be mounted on the shank rack, with the possibility of rotation on the shank and interaction with the curly groove of the blocking curtain to facilitate kinematic interaction due to rolling friction. There may be another design when a roller (10) is installed on the shank rack, the inner hole of which is square or shaped, without the possibility of rotation of the roller on the shank to facilitate kinematic interaction due to sliding friction. For the same purpose, at least one additional roller (12) can be installed on the roller (11), which interacts with the curly groove of the blocking curtain.

The castle works in the usual way.

Shutters do not allow you to open the lock with unauthorized tools. This is ensured by the fact that when the lock is opened with a master key, the shutter moves and blocks the keyhole and also clamps an unauthorized tool inside the lock without the possibility of removing it.

Claims (4)

1. A level lock containing a cover (1) with a housing (2), inside of which there is a deadbolt (3) with a bolt shank plate (4), on which a shank stand (5) is fixed, spring-loaded code levers (6) with code grooves, installed on the side of the shank stand with the possibility of their movement in the transverse direction relative to the movement of the shank stand, at least one blocking shutter (7) containing a curly groove (8) interacting with the shank stand, while the blocking shutter is installed with the possibility of its shifting in the transverse direction relative to the movement of the shank stand and the overlap of the keyhole (9), characterized in that at least one blocking shutter is placed between the levers or between the levers and the bolt shank plate. 2. The level lock according to claim 1, characterized in that a roller (10) is mounted on the shank rack, with the possibility of rotation on the shank and interaction with the curly groove of the blocking curtain. 3. The level lock according to claim 1, characterized in that a roller (10) is installed on the shank rack, the inner hole of which is square or shaped, without the possibility of rotation of the roller on the shank. 4. A level lock according to any one of claims 2 and 3, characterized in that at least one additional roller (12) is installed on the roller (11), which interacts with the curly groove of the blocking curtain.
