Abstract

FIELD: construction.

SUBSTANCE: invention relates to manufacturing method of assemblies, each of which consists of code, support pins and a spring, in cylinder secret mechanisms of a lock, and namely to door locks and can be used in dead and rim lock models. Maximum protection of the proposed lock secret mechanism is achieved at total equality of sums of lengths of code and support pins of all assemblies; when the above requirement is not met, lock secret mechanism protection degree is decreased. In other words, improvement of stability to unauthorised opening of a lock secret mechanism is achieved owing to using at least one pin of the length that is different from other support pins. In order to exclude decoding as per the above way, it is proposed according to the technical decision of the second version to randomly install springs with different mechanical characteristics into assemblies and/or individual elements retaining the assembly in the lock mechanism housing, to make support pins that are different as to length from each other and/or at least one support pin with length that is different from that of other support pins.

EFFECT: improving stability to unauthorised opening of a lock secret mechanism by means of high-sensitivity fake keys, the operating principle of which is based on reading of a code of the secret lock part.

Description

The proposed invention is a method of manufacturing assemblies, each of which consists of a code, support pins and a spring, in cylinder mechanisms of the lock secret relates to door locks and can be used in mortise and patch models.

Cylindrical mechanisms of lock secrets are known (see http: // www. Moyzamok.ru/cyl_mech).

The disadvantage of these cylindrical secrets is the possibility of unauthorized unlocking by decoding using highly sensitive devices that can freeze and compare the difference in the compression forces of the springs supporting the pin assemblies.

The secret of the Gedra-Titan lock is known, which contains a rotary cylinder with a round hole in the housing, in the center of which there is a support stand fixed motionless in the lock secret housing, as well as spring-loaded support and code pins (see http: //www/gerda.pl ./rus/).

The disadvantage of these cylindrical secrets is the possibility of unauthorized unlocking by decoding using highly sensitive devices that can measure and compare the difference in the compression forces of the springs supporting the pin assemblies.

The closest in technical essence to the proposed one is a method of manufacturing a cylinder mechanism for a lock secret, comprising a housing with a rotary cylinder placed in it with a round hole, in the center of which there is a support post fixed to the internal rotary cylinder, spring-loaded support and code pins (see application No. 2011125818 dated 06/23/2011).

The disadvantage of this manufacturing method is the high degree of possibility of unauthorized unlocking using high-precision electronic and mechanical devices, the principle of operation of which is based on measurements and comparison of the compression difference of the springs and identical to each other.

The technical result of the invention is to increase resistance to unauthorized opening of the lock secret mechanism with the help of highly sensitive lock pick probes, the principle of which is based on reading the code of the secret part of the lock.

The technical result of the first embodiment of manufacturing assemblies, each of which consists of a code, support pins and a spring, in the cylinder mechanisms of the lock secret, in each of which whether for all of them there is an element that holds them in the case of the lock mechanism, is achieved by the fact that with equal depths of the channels in which the assemblies are located, the sum of the lengths of the code and support pins in the assemblies is made constant, and the springs are used the same length with the same mechanical characteristics, while the support e pins may be made or assembled or undivided.

The technical result according to the second embodiment of manufacturing assemblies, each of which consists of a code, support pins and a spring, in the cylinder mechanisms of the lock secret, in each of which or for all of which there is an element that holds them in the case of the lock mechanism, is achieved by the fact that in the assemblies used springs with different mechanical characteristics and / or the elements holding the assembly in the housing of the lock mechanism are made of different lengths and / or the implementation of at least one support pin with a length different from the length of the other support pins, while springs with different mechanical characteristics in the assemblies can be installed randomly, while the elements holding the assembly in the lock body can be installed randomly.

The invention is illustrated by one of the possible embodiments of the assemblies, each of which consists of a code, support pins and a spring using the cylinder lock mechanism as an example with a common element holding the assemblies in the lock case (Fig. 1); Fig. 2 shows the existing assemblies of various lock manufacturers , each of which consists of a code, support pins and a spring, in the cylinder mechanisms of the secret of the lock with their holding element in the body of the cylinder mechanism; figure 3 shows the assembly of locks in the first proposed embodiment; figure 4 shows the assembly of locks according to the second proposed embodiment of their execution with different depths of pressing in the retaining element (plugs, plugs); figure 5 shows the assembly of locks according to the second proposed embodiment of their execution with holding elements (plugs, plugs) of different lengths. Figure 2-5 shows the assembly with individual elements of their retention in the cylinder mechanism.

The cylinder lock mechanism comprises a housing 1, in the central longitudinal opening of which an inner rotary cylinder 2 is located, having a turnkey hole in the center 3 and fixedly fixed to it, located in the center of the keyhole, a support column 4. In the housing 1 and the inner rotary cylinder 2 coaxial transverse holes 5, in which are located the locking elements of the code pins 6 and spring-loaded springs 7 support pins (pushers) 8, the code pins 6 interact with the key (key not shown) through balls 9. Elements 1-9 are placed in a cylindrical frame (element) 10, which ensures that all elements of the secret are kept in working condition. A similar numbering of the elements is given in FIGS. 2-5, namely: 1 denotes a housing, 5 denotes holes in which the assemblies are located, each of which consists of a code pin 6, a support pin 8, a spring 7, a holding element (plugs, plugs) 10. In FIGS. 2-5, for a better understanding of the essence of the proposed element (plugs) 10 are shaded with vertical lines, support pins with horizontal lines, code pins with horizontal and vertical lines at the same time. Position 11 shows the conditional line of the individual profile of the keyhole section, beyond which the code pins extend. 2-5, the code pins in contact with line 11 are conventionally shown non-rounded.

The castle operates as follows.

When the key is inserted (the key is not shown in the drawing) into the keyhole 3, the secret pins 6 are installed according to the code, which makes it possible to rotate the internal rotary cylinder 3 interacting with the lock bolt (the lock bolt is not shown in the drawing).

All manufacturers of mechanisms have code pins of different lengths, and the support pins are all the same in length. The manufacturing technology for secrets of cylinder mechanisms in this way is beautifully illustrated in photographs shown on the Internet (see www.Dwerizamki.org/Wiki). Because of this, the compression forces of the springs are different. This makes it possible to decode the lock using sensitive instruments capable of measuring and comparing the compression difference of identical springs.

To exclude decoding along the indicated path, according to the technical solution according to the first embodiment, it is proposed that, with the same mechanical characteristics of the springs, the total length of the pins 6 and 8 is the same in each assembly.

The maximum protection of the proposed lock secret mechanism, according to the technical solution according to option 1, is achieved with the total equality of the sums of the lengths of the code and support pins of all assemblies without exception, with the advent of assemblies with failure to fulfill the above requirements, the degree of protection of the lock secret mechanism is reduced. In other words, increasing the resistance to unauthorized opening of the lock secret mechanism is achieved by using at least one support pin of an excellent length from other support pins.

To exclude decoding according to the aforementioned path, according to the technical solution according to the second embodiment, it is proposed to install springs with different mechanical characteristics and / or individual elements holding the assembly in the lock mechanism case in assemblies randomly, to make them different in length from each other, and / or to perform at least one support pin with a length different from the length of the other support pins.

To increase the reliability against unauthorized unlocking of the lock secret mechanism in one cylinder mechanism, for example, shown in Fig. 1, both versions of the proposed technical solution can be used simultaneously, compared with the prototype, there is high resistance to unauthorized opening of the lock secret mechanism using highly sensitive probes - master keys, the principle of which is based on reading the code of the secret part of the lock.
