#CMT# #/CMT# The device has a cylinder (3) supported in a lock frame (2) in a rotatable manner. A tumbler unit (8) is movable in the cylinder through a key insert, where a locking unit i.e. elastically supported latch and/or a bar, is movable through rotation of the cylinder. A rotating angle limiter is assigned for cylinder movement, where the limiter is conquerable during usage of a key (6), which is provided with a recess that permits the limiter to pass a plane of the key. The limiter interrupts operation of the device during usage of a key (5), and is formed of screws, pins and rivets. #CMT#USE : #/CMT# Locking device for a room door, cabinet door and an access control for a technical system. #CMT#ADVANTAGE : #/CMT# The design of the device enables the device to avoid opening possibility of the locking device despite insertion of a key with suitable key bit and permits opening possibility of the locking device when the key is provided with the recess, thus achieving additional distinction possibility of keys with similar key bit, increasing the number of coding in a series production of the locking device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a cylinder with a key that is adapted to a rotating angle limiter and inserted into a groove and another key inserted into the cylinder. 2 : Lock frame 3 : Cylinder 5, 6 : Keys 8 : Tumbler unit 9 : Annular gap 11 : Acceptance region. |
