GUIDE PIN OF SUVALDNY LOCK

The utility model relates to hardware, namely, to the design of the bolt plate of the lock carrying the guide pin and designed to increase the reliability of the protection of the castle from unauthorized use.

As analogues, patented design solutions of locks were selected, namely:

Patent of Great Britain No. 3772904, 15/10, publ. 1941, which describes a lock with a bolt having a bolt plate with a guide pin attached to it.

The disadvantages of the known solutions include insufficiently high protective functions of the code part of the level lock, due to the possibility of unauthorized unlocking of the lock by phased fixing of the level plates with a master key using friction forces in the code part.

Patent of the Russian Federation No. 2175705, E 05 B 35/04, publ. November 10, 2001, a feature of the patented lock is the use of means in the design of the code assembly to prevent unauthorized unlocking of this assembly by drowning, distorting or simulating signals arising between the bolt and the code latches, or elements intermediate between the code latches and the bolt. A disadvantage of the known castle is the relative complexity of the design of the secret part, due to the presence of means for generating a false signal, mechanically associated with the secret part of the castle.

As the closest analogue, the invention is selected according to US patent No. 2089417. According to this invention, a level lock with a crossbar having a crossbar with attached bolts and a guide pin made in the form of a rod of rectangular cross section, mounted on the crossbar plate with the possibility of interaction with the leveling plates is patented.

Known level locks, including the closest analogue, are characterized by the presence of structural gaps between the guide pin and the grooves of the code section of the level plates in the direction of movement of the crossbar. In case of an unauthorized attempt to open the lock at the moment of picking up the working section of the guide pin with a picklock, the position of the level plates is fixed in the lock mechanism due to friction forces. After installing the leveling plates in the position necessary to move the bolt, by further turning the master keys, the bolt is moved and the lock is unlocked.

These design features of the level locks led to the appearance of significant drawbacks - to weakening the protection of the level lock from unauthorized use due to the possibility of unlocking the secret part of the lock by affecting the level plates with a master key, setting each of them in the unlocking position of the bolt plate.

The task the utility model is aimed at is to increase the degree of protection of the level castle from its unauthorized use and to improve the operating conditions of the castle.

The technical result consists in the formation of a false situation in which the leveling plates supposedly occupy the position necessary to move the crossbar and thereby open the lock. it

it became possible if the guide pin had two extreme working sections that form a false signal on the master key.

To achieve a technical result with the known guide pin of the crossbar of a level lock made in the form of a rod with parallel sides in the section and mounted on the crossbar with the possibility of interaction with the leveling plates, two opposite sides of the rod located along the direction of movement of the crossbar are made stepwise having three working areas, two extreme for the formation of a false signal and one central, located above the plane of placement of the extreme sections with the ability to place level plates in the position of the crossbar.

In addition, the width of the central portion may be equal to or less than half the width of the guide pin;

In addition, the central portion can be mated along an arc or an inclined line with the extreme portions.

In addition, the angles of the guide pin may be rounded and / or beveled.

In addition, the outer surface of the guide pin may be heat treated followed by surface cementation.

The above signs characterizing the construction of the crossbar plate of the level lock are essential and interconnected causally with the formation of a set of essential signs sufficient to achieve a technical result, in particular for the formation of a false situation in which the level plates supposedly occupy the position required for moving the bolt followed by unlocking the lock.

The essence of the utility model is illustrated by drawings, where in FIG. 1 shows a general view of the castle of castle; figure 2 shows the guide pin; in Fig. 3 is a cross section of a guide pin.

The utility model is illustrated by a specific implementation example, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving this set of essential features of a given technical result.

According to a utility model, the level lock comprises a housing 1 (FIGS. 1, 2, 3), in which a bolt is mounted movably, made in the form of a plate 2 with bolts fixed on it and a guide pin 3 in the form of a rod with sides parallel in cross section and located on the crossbar plate 2 with the possibility of interaction with the leveled plates 4.

In order to generate a false signal when trying to unlock the lock part of the secret part of the level lock, two opposite sides 5 and 6 of the rod 3 are made in a stepped form. Moreover, each side 5 and 6 has three working sections located at different levels and oriented in the direction of movement of the leveling plates 4. Two extreme 7 and 8 working sections are designed to generate a false signal and one working section is the central 9, which is located above the placement plane extreme sections 7, 8 and is designed to place the level plate 4 in the position of movement of the crossbar plate 2. It has been experimentally established that for reliable operation of the level lock you must fulfill the condition about which the width of the central section 9 is less than half the width of the side of the rod on which the central section 9 is located. It is possible to perform the central section 9 in the form of a “dovetail, the larger side of which serves as the working surface of the central section 9, this solution is aimed at complicating the transition of the master key to this astok.

In order to improve working conditions with a simultaneous increase in the lock, the lock width, the central section 9 is guided, its pin 3 can be mated in an arc or an inclined line to the extreme sections 7 and 8, and its corners are made rounded and / or beveled.

To increase the strength properties of the guide pin 3, the outer surface is heat-treated with the following; surface cementation, which excludes mechanical damage, for example, drilling.

The device operates as follows.

Known constructions of lever locks are characterized by the presence of structural gaps between the guide rails, the pin 3 and the grooves 10 of the code lock of the lever plates 4 in the direction of mixing; the bolts 11 of the bolt plate 2 are thus unauthorized. plates 4, when interacting with the working section you are guiding them; its pin 3, made in its entire width, is trying to fix the position due to the friction forces in the mechanical part of the lock the corresponding level plate 4. Similar actions are performed in relation to other level plate 4. After installing the level plates 4 in the position necessary to move the crossbar plate 2, an unauthorized opening of the lock is performed.

The proposed design of the guide pin completely eliminates the implementation of the above situation. Due to the presence of extreme working sections 7 and 8, a false signal is fixed with a master key.

characterized by the interaction of the master key on the lefthand plates 4, interacting when the master key is rotated with the extreme sections 7 or 8 of the guide pin, and not with the central section 9, which ensures the position of the leveling plates 4, in which the guide pin 3 will be unlocked in the direction of movement of the bolts 11.

Thus, each leveling plate 4 under the action of the master key moves along the stepped side of the guide pin 3 until the moment at which the pick does not feel that a further turn of the master key around its axis will lead to the movement of the bolt plate 2 with bolts fixed to it. This sensation is false and is determined by the presence of extreme sections 7 and 8, allowing the master key to move the crossbar plate by an amount equal to the step height when it moves the leveling plate 4, resting on the central section 9 at the first stage, going to section 7 or 8 - "H. Having felt this signal on the master key, as indicated above, this leveling plate 4 is fixed, assuming that it has unlocked the guide pin 3. That is the feeling on the master key during the interaction of the leveling plates 4 with the extreme sections 7 or 8 of the guide pin 3 is similar to the feeling when the plates 4 interact with the central section 9 with the only difference that in the first case the guide pin 3 is not set to a position sufficient to move the bolt plate 2, and in the second case, the pin 3 is installed in the longitudinal groove 11, designed to move it when exposed to the teeth of the crossbar platinum 2 with a lock pick or key. Such a solution can significantly increase the reliability of the secret part of the level lock, increase security against unauthorized 6

use without changing the design of the secret part, i.e. without significant complication of the level lock.

The utility model meets the patentability condition “industrial applicability, since its implementation is possible using existing means of production using well-known technological operations. The manufactured prototypes confirm the possibility of achieving a technical result.
