FIELD: mechanics.
SUBSTANCE: invention relates to cylindrical locks. Proposed lock mechanism incorporates the cylinder with key channel, arranged in the casing to revolve about its axis. The casing and cylinder have coaxial holes and spring-loaded locking pins. The cylinder holes accommodate pushers arranged to eliminate their slippage into the key channel by resting them upon stop plate fitted on one wall of the key channel. The key channel lower end face consists of two parallel end faces with inclined heads. While key plate lower end face consists of two parallel end faces with inclined bevels to allow key plate end faces to get aligned with key channel end faces and, at a time, to allow key plate going up and key ledges to interact with pushers end faces.
EFFECT: improved lock combination, impossibility to unlock cylindrical mechanism.
