LOCK MECHANISM PRIMARILY FOR STRONGBOXES
The invention is a lock mechanism primarily for strongboxes, with reeling wheels (3), rotating buttons (4), and lock bolt (5), so that the reeling wheel (3) is connected to the lock bolt (5) through a driving unit It is characterized in that it has a ribbed part (17) and a disc case (24) connected to the ribbed part (17) with central cogwheels (18), and the rotating button (4) is located on the ribbed part (17), and the disc case (24) includes a cog disc (37) and a receiving disc (38), and the ribbed part (17) includes an indicator plate (35) and an indicator axis (36), and the cog disc (37) has fitting cogs (39) and at least one shaped cog (40), and the receiving disc (38) has fitting pockets (42) and at least one shaped pocket (43). Only when all cogs fit into the respective pockets the receiving disks (38) can be axially moved towards the cog discs (37) by pressure on the reeling wheel (3), thus a bolt (31) frees the reeling wheel (3) for rotation to drive the lock bolt (5).
