Abstract:
Assembly comprising a tumbler lock with the appropriate key, the lock comprising a barrel or rotor (2) turning in the bore of a lock body or stator (1), said rotor (2) comprising a blind longitudinal slot provided with a key inlet for the introduction of a serrated key (3), said rotor (2) comprising a plurality of transverse through slots (2b) and crossing the longitudinal slot in each of which is mounted a tumbler urged to project from the rotor (2) by a spring, each tumbler comprising a window arranged to be traversed by the key (3) whose serrations coact with an edge of said windows, the tumblers being all retracted by introduction of the serrated key (3) corresponding to the combination of the lock or to a pass combination, the bore of the stator (1) comprising a hollow for reception of each tumbler projecting from the rotor (2),the lock moreover comprising a slide (4) movable transversely to the key channel, said slide (4) comprising an opening (41) for passage of a key and a projection (42) coacting with a recess (11) on the stator (1) in the locking position of rotation of the rotor (2) and resiliently urged to said locking position by means of resilient return means (5), said slide (4) having at least one peripheral notch (43) coacting with an axial pin (31) secured to the key so as to drive transversely said slide (4) toward a position for unlocking the rotation of the rotor (2), said pin (31) for the peripheral notch (43) having an inclined plane arranged so as to drive the transverse movement of the slide (4) in the direction to retract said projection (42) from the recess (11) of the stator (1).
