CYLINDER LOCKING MECHANISM WITH KEY Russian patent published in 2008 - IPC E05B47/00 

FIELD: construction.

SUBSTANCE: invention pertains to locking equipment. Cylinder mechanism of the lock with a key contains a body frame with an opening for the key and code system set inside. Its blocking elements made in the form of balls of magnetically sensitive material are arranged moving freely restricted by the size of corresponding grooves correspondingly in longitudinal and T-shaped grooves made on the external and internal cylinders. Longitudinal grooves are in coincidence with the longitudinal part of T-shaped grooves in the closed state of the cylinder mechanism. Internal and external cylinders are set coaxially in the body frame. Shank is fixed on the back flat end of the internal cylinder. Constant magnets forming code pattern are fixed in the working part of the key. Number and location of code elements, as well as their grooves corresponds to the number and location of constant magnets.

EFFECT: higher operational safety through design simplification, exclusion of spring - controlled elements and through a possibility of increasing number of code patterns.
