Cylinder lock with sliding axial tumblers - has tumbler pins with lugs in sliding seats and has circumferential retaining groove

摘要

The cylinder lock has a rotating core and six axial tumbler pins. These pins are pushed axially in their channels by the axially inserted key with given coding profile. This lock resists unauthorised forcible operation. The sliding tumbler pins (12) have projecting locking lugs (18). The lugs are prevented from rotation but are able to slide axially. The cylinder housing (2) has a circumferential groove (22). The locking lugs are able to rotate freely within the groove when the lock is released.
