MANUFACTURING METHOD OF ASSEMBLIES, EACH OF WHICH CONSISTS OF CODE, SUPPORT PINS AND SPRING, IN CYLINDER SECRET MECHANISMS OF LOCK (VERSIONS) Russian patent published in 2014 - IPC E05B27/06 

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.
