BARDACHENKO CYLINDRICAL LOCK
The inventive Bardachenko cylindrical lock relates to locking devices and consists of a body, a rotatable cylinder comprising a pack of locking plates provided with windows for a key and units for mounting said locking plates each of which is provided with a spring and two rest pads for the cylinder and the plate projection. The axis of the channel of the key cylinder and the transversal axes of the plate windows pass through the centre of the rotatable cylinder. The contacting edges of the plate windows are arranges symmetrically with respect to the transversal axes of the windows and the longitudinal dimensions of the plates are shifted with respect to said axes at a distance equal to the size of the blocking ends thereof. The plates together with springs form replaceable code blocks and the units for mounting plates are provided with elements for transmitting the spring efforts to the cylinder rest pads. Said invention makes it possible to reduce the information content of the locking plates of the lock, thereby increasing the secrecy thereof and enabling the lock to re-encoded to any code combination of the key.
