Abstract (en)

There is provided a key operated cylinder lock mechanism, which comprises a housing (3), a barrel (5) rotatably mounted within the housing, and a set of discs (7) rotatably mounted within the barrel about an initial key insertion position, the set of discs (7) comprising a plurality of locking discs which are rotatable by means of combination surfaces on the shank (9) of the key. The cylinder lock mechanism also comprises a first locking bar (12) disposed in the barrel and operable to engage the housing to prevent rotation of the barrel from the initial key insertion position, and a peripheral notch (18) on each disc adapted to receive said locking bar whereby correct alignment of the peripheral notches in the discs forms an opening into which the locking bar can pass to release the barrel and thereby permit the barrel to rotate. The cylinder lock mechanism further comprises a second locking bar (31) disposed in the barrel and each of the discs (70) has a second peripheral notch (40) which when aligned form an opening for receiving the second locking bar. The cylinder lock mechanism may also have spring means (72) acting radially on one or more of the locking discs separately urging each locking disc towards a rest position. <IMAGE>
