Abstract

Lever lock containing a key hole blocking device, including leveler plates installed on both sides of the package, each of which is made with a shaped groove interacting with the bolt shank post to ensure movement and overlap of each of the key hole plates when the bolt moves.

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, a key hole locking device in the form of a protective plate mounted parallel to the levers and spring-loaded relative to the housing (see RU 2360088 C1, MKI E05B 17/14, publ. 27.06. 2009). The protective plate has a figured, mainly T-shaped groove for introducing the key into the lock hole, a spring and a L-shaped leash (protrusion or shelf), which overlaps the first few levers of the mechanism and is involved in lifting the protective plate.

The disadvantage of the analogue is the lack of the function of capturing tools for unauthorized opening (for example, master keys), which allows you to freely remove them from the well after each half turn of the key when trying to open the lock.

Also known from the prior art is a device for locking a key hole of a level lock, patent RU 96392 U1, MKI EV 05/17, publ. 07/27/2010, containing a plate with a figured groove installed on one side of the suvald package, moreover, the figured groove of the plate interacts with a pin mounted on the crossbar to ensure that the plate moves and overlaps the key hole when the crossbar moves.

The known device performs the function of capturing tools for unauthorized opening (for example, master keys). However, for this, several curly grooves are used that are quite complicated in design and an additional means of interaction with the curly groove in the form of a pin.

The level lock with increased security is known from the prior art, comprising a case with a cover, inside of which there is a code mechanism of a level type, spring-loaded level plates of which are mounted on the side of the liner strut with the possibility of their movement in the transverse direction relative to the movement of the bolt shank, to which steel rods from calibrated steel, in the code grooves of the leveling plates there is a rack fixed to the bolt shank, while the lock is spring-loaded th locking plate made with a device for controlling its movement and located on the outer side of the extreme level plate with the possibility of blocking the keyhole after the first and until the last half-turns of the key, occupying during this period a position in the groove made in the middle of the keyhole (see RU 114082 U1, MKI E05B 21/00, publ. 03/10/2012). This device is the closest analogue (prototype).

The disadvantage of the prototype is that the lock with such a device can perform its function only on one side of the door, which reduces its burglar resistance and leads to the need to have two designs of the lock for the possibility of installation in the door of the right and left opening.

The objective of this utility model is to develop a device devoid of these disadvantages.

The technical result of the claimed utility model lies in the possibility of its use for left and right door openers, which leads to an increase in the resistance of the lock to hacking in general.

The claimed technical result is ensured by the fact that the level lock contains a key hole locking device, including plates installed on both sides of the package, each of which is made with a curly groove interacting with the crossbar strut to ensure that, when the crossbar moves, each of these key plates moves and overlaps holes.

The implementation of an additional plate overlapping the key hole on the other hand allows you to use the lock on both sides of the door, i.e. both the left door version and the right one.

Also a feature of the claimed lock is the use of an existing deadbolt shank in the structure of the lock for raising and lowering the plates.

The utility model is illustrated by figures. Figure 1 shows a longitudinal section of the castle body with plates, pins and racks of the key hole locking device, figure 2 is a transverse section of the castle body.

The device comprises a housing 1, a package of suvald 2, plates 3 and 4 with corresponding figured grooves 5 and 6, auxiliary grooves 7 and 8 on each of the plates 5.6, a key hole 9, a bolt 10 with a rack of a shank of a bolt 11, guide racks 12, 13 in the corresponding auxiliary grooves 7 and 8.

In the housing 1, two plates 3, 4 with a figured groove 5 and 6, respectively, and auxiliary grooves 7, 8 are located symmetrically with respect to the bolt 10 on two sides on top of the suvald 2. The each plate 3, 4 interacts with two auxiliary grooves 7, 8 with guide racks 12, 13, and with figured grooves 5 and 6, respectively, with a rack 11 of the bolt shank and has the ability to plane-parallel movement (up and down).

During operation of the device, the key is inserted into the key hole 9 and the key is turned.

After installing the package Suvald 2 according to the key code, the bolt 10 moves forward and at the same time each plate 3, 4 is lifted with a figured groove 5 and 6, respectively, the lift is carried out by the interaction of the rack 11 of the bolt shank with the figured grooves 5 and 6 of the plates 3 and 4.

After the first half-turn, the post 11 of the crossbar shank goes to the horizontal generatrix of the curly grooves 5 and 6 on the plates 3 and 4, respectively. The plates 3 and 4 rise, the key hole 9 is closed, only its central part remains accessible.

On the second and third half-turns of the key, the plates 3 and 4 are in place (the key hole is blocked). On the fourth half-turn of the key, the rack 11 of the bolt shank again slides along the inclined part of the curly grooves 5 and 6 of the plates 3 and 4. At the end of the fourth half-turn of the key, the plates 3 and 4 fall to their starting position. Key hole 9 is released. The key can be removed. In intermediate positions, the key cannot be removed from the lock (in order to remove the key, the lock must always be opened / closed four half turns).

Plates 3 and 4 serve as protective curtains and, first of all, protect against opening the lock with the help of master keys. Such, for example, as a self-dialed key, a dialer, a master key with a stretch. If during the work with the master key on the first half-turn it is possible to set the levers of package 2, then further the protective plates 3 and 4, which have risen along the figured guiding grooves 5 and 6, will block the key hole 9 and clamp the master key, thereby preventing further manipulations with the lock.

A feature of this utility model is the use of a bolt shank rack to move the plates, as well as a bilateral symmetrical arrangement of plates with curly grooves (protective curtains).

The utility model also allows you to have one design for doors, right and left opening.

In addition, when closing the lock from the inside with the bolt left in the middle position, the well is blocked from the outside and there is no way to push out the key and open the lock, etc.
