ABSTRACT:
A cylinder lock comprising a stationary cylinder housing and therein a turnable cylinder inclosing a plurality of tumbler discs turnable by means of the key of the lock. There is also a locking bar normally locking the cylinder non-turnably to the cylinder housing. When the tumbler discs have been brought to a releasing position, the locking bar can move closer to the center of the lock into a groove formed by alignment of peripheral recesses in the tumbler discs, and this releases the cylinder from its locking. In the lock there is also at least one composite tumbler disc including two parts, a first part and a second part, which are angularly adjustably connected to each other. The first part can be turned with a key. Within an adjustment sector the first part has such a small radial extension that it leaves the locking bar free to move radially to its cylinder-releasing position. Within the same adjustment sector the second part of the composite tumbler disc has a support surface preventing the locking bar from moving radially to its cylinder-releasing position but has also a peripheral recess allowing the locking bar to reach its cylinder-releasing position. Between the first and second parts of the composite tumbler disc, there is an adjustable clutch device allowing setting of the first and second parts to a plurality of different, functionally fixed angular positions relative to each other. There is a specially designed setting key to be used for setting of the composite tumbler disc to another position, thereby changing the lock combination.
