A tumbler pin lock includes one or two auxiliary locking mechanisms including an auxiliary locking pin, and an auxiliary blocking component to provide enhance locking in addition to the locking provided by the tumbler pins so that the lock remains locked even if the tumblers are picked or bumped into their unlocked positions. A cylinder lock is provided with an auxiliary locking pin which projects into the keyway, which, with the proper key, is slid forward with a mobile device into an area in the lock housing where an auxiliary groove allows the cylinder plug to turn. The second locking component, which is approximately rectangular similarly has a post that is moved forward with the insertion of the proper key into an annular groove allowing the cylinder plug to turn.

A key (1) for a rotary cylinder lock (2) comprises a key grip (3) and a key shank (4), which adjoins the key grip (3) and extends along a longitudinal axis (L), wherein the key shank (4) has, on its outside (5), control recesses (10), in particular control bores, for properly positioning tumblers on the rotary cylinder lock (2) and also has at least one control element (6) arranged in a movable manner in the key shank (4), which control element (6) has a control surface (8), which interacts with a tumbler (7) of the rotary cylinder lock (2). Furthermore, the key is characterized in that the key shank (4), in the region of the control element (6), has a tapered cross section (9), which is tapered in relation to the cross section (11) with the control recesses (10).

A cylinder lock device includes a body, a rotor rotatably arranged inside the body, a holder lever rotationally driven according to a rotation of the rotor, an engagement lever that is link-connected to the holder lever so as to be angularly adjustable and rotationally driven according to a rotation of the rotor, and a retention mechanism to hold the engagement lever into a predetermined direction relative to the body. The retention mechanism is configured to force a protrusion on the engagement lever to contact the holder lever by an elastic force thereof.

A clutch driving module is disposed in a lock which is able to drive the clutch driving module selectively to control an exterior handle assembly whether be able to drive a latch assembly in lock or unlock or not. And the clutch driving module is able to respectively make an interior handle assembly and the exterior handle assembly controlling the lock in lock or unlock independently.

A method for mutually controlling and unlocking a dual plug in a lock includes: unlocking a code of a first plug first, the first plug restricting unlocking of a second plug, the second plug restricting rotating of the first plug before the code of the first plug is unlocked. after unlocking the code of the first plug, the first plug translating to a second position from a first position using a preset position difference, the first plug being unable to rotate during the translation; after moving the first plug to the second position, the first plug releasing a restriction on the second plug, the second plug still restricting the rotating of the first plug; and unlocking the code of the second plug, the first plug and the second plug being able to rotate synchronously so as to unlock the lock after unlocking the code of the second plug.

A lock (1) is described, comprising: a body (2) suitable to define a housing (3) having a longitudinal development direction (L) along an insertion direction (I) of a key (200), said housing (3) comprising a first portion (4) and a second portion (5) mutually adjacent along the longitudinal development direction (L) of the body (2); a first rotor (37) suitable to be rotationally housed within the first portion (4) of said housing (3) of such body (2) about the longitudinal development direction (L) of the body (2), said first rotor (37) being suitable to define a further housing (38); a second rotor (39) comprising a first portion (55) suitable to be rotationally housed within the second portion (5) of said housing (3) of the body (2) about the longitudinal development direction (L) of such body (2), said second rotor (39) comprising a second portion (56) suitable to be rotationally housed within the further housing (38) defined by the first rotor (37) about the longitudinal development direction (L) of such body (2). The second rotor (39), by the insertion of the key (200), is suitable to translate along the longitudinal development direction (L) of the body (2) with respect to the first rotor (37). The second rotor (39), by a first rotation portion of the key (200), is suitable to rotate about the longitudinal development direction (L) of the body (2) with respect to the first rotor (37), to pass from a disengagement position to an engagement position with said first rotor (37). In the engagement position, said first rotor (37) and said second rotor (39), by a second portion of rotation of the key (200), are suitable to integrally translate along the longitudinal development direction (L) of the body (2) to reach an actuating position of the lock (1).

A locking assembly for a dispenser may include a locking component and a barrel. The locking component is movable between (i) a first position configured to lock a cover of the dispenser, and (ii) a second position configured to unlock the cover. The barrel is rotatable between (i) a first barrel position configured to resist movement of the locking component, and (ii) a second barrel position configured to permit movement of the locking component. The barrel defines a barrel opening configured to receive a key or a push button. A dispenser including a dispenser plate and a cover may further include the locking assembly. The dispenser defines an interior closable with the cover. The cover is movably coupled to the dispenser plate. The locking assembly releasably secures the cover to the dispenser plate.
