Cylinder lock with disc tumblers

摘要

The lock has an inner cylinder housing (1) supported in an outer cylinder housing, where a locking disk (4) is arranged in the inner housing and has a key. The key and a keyhole (4.1) have complementary combination surfaces for bringing a circumferential groove (4.2) in an alignment position by rotation of the disk. An additional locking mechanism hinders the rotation of the key before the complete axial insertion of the key into the lock in the key end position.
