Kind Code:
A1
Abstract:
The present invention pertains to the field of locking devices and more precisely relates to cylindrical mechanisms which can be used in various lock structures such as door locks. This cylindrical lock mechanism includes a drum having a groove formed therein, wherein fixation plates (3) capable of vertical displacement are mounted in said groove. These plates comprise rectangular openings whose lead-in contact surfaces are located under the key. When the lock is in a locked position, said openings extend horizontally and are vertically offset relative to the centre of the plates. Each plate has its own eccentricity. The inner surface of the drum comprises a plurality of diametrically opposed slots. This invention can be used for simplifying the mechanism structure and for reducing malfunction risks.
