A PROGRAMME FOR THE PROVISION OF THE CODE AND THE KEYS FOR THE OPERATION OF THE CODE

摘要

a programmed cylinder lock comprising a stator (1) and a cylindrical rotor (2),placed within the stator (1) for rotation around its axis and having a keyhole for inserting a key (3),and containing within the rotor (1) a number of key sequences (5) with the ability to move along the longitudinal and transverse directions,intended for cooperation with a key entering the rotor keyhole (2),and insurance experience (6) with the ability to move along the longitudinal direction,key followers (5) and insurance experts (6) who together form a number of pairs and have teeth intended to cooperate with each other in order to: the lock encoding is defined,rotor (2) comprising a brake rod (9) which cooperates with a longitudinal rocking (10) of the stator (1) and which has the possibility to cooperate with insurance experts (6) in order to: be immobilised,and includes a change bar (11) which comes into contact with slip capability with the key followers (5) in order to maintain normala key followers (5) in conjunction with insurance experience (6) when this change bar (11) provides a lock programming position;characterised by the fact that the key sequences (5) have a protrusion (7) that combines a side surface of the key and,when in contact with a normal use key (12),prevents the transverse movement of the key sequencer (5) and the change bar (11),and therefore the disassembly of the key sequences (5) from the insurance experience (6),and that protrusion (7),when contacting a special change key (14),allows the transverse movement of the key sequencer (5) and the change bar (11),and therefore the disassembly of all key sequences (5) from the lock's insurance experience (6).
