Abstract: The present invention concerns an electromechanical lock (1), comprising: a solenoid (2) a movable locking element (3) displaceable by said solenoid (2) into an unlocking position of the lock (1) a spring (4) acting on said movable element (3) to hold it in a locking position of the lock (1) with the solenoid (2) in a de-energized condition wherein said movable element (3) comprises an anti-shock shaped portion (31,31?,31?,31??) and said lock (1) comprises an engagement means (8,8?,8?,8??) for said anti-shock shaped portion, said engagement means (8,8?,8?,8??) is displaceable into an engagement position in which it interferes with the anti-shock shaped portion (31,31?,31?,31??) in order to prevent said movable element (3) from displacing into the unlocking position of the lock wherein said lock it further comprises a substantially cylindrical and hollow rotor (6), intended to house said solenoid (2) and said movable element (3) such that one end of the latter provided with said anti-shock shaped portion

Abstract: A lock with a programming device, includes a stator, a rotor rotatably inserted therein, a keyhole, a longitudinal groove, a set of key followers and a set of locking pins which, under control of a change bar, can be mutually engaged for normal operation and disengaged in a change condition, and can be moved or blocked under control of a stop bar provided with springs which stress the stop bar outwards. The change bar is arranged to keep or assume, even in the change condition, a position in which it retains the engagement among at least some of the key followers and locking pins. A change element displaces the change bar to the position in which it disengages all the key followers from the locking pins, when the user intends to proceed with the change of the key. A device for preventing a faulty programming is provided.

Abstract: A programmable cylinder lock includes a stator and a cylindrical rotor, mounted therein for rotation around its own axis, has a keyhole, and comprising inside the rotor key followers movable along the longitudinal and transversal directions, and locking pins movable along the longitudinal direction, the followers and locking pins forming together a number of pairs and having toothings for mutually cooperating to define the lock codification, the rotor including a stop bar cooperating with a longitudinal groove of the stator and cooperating with the pins to immobilize them, and a change bar slidingly coupled with the followers to keep them engaged with the pins and to disengage them therefrom when the bar provides a lock programming position. The followers have a projection which engages a side surface of the key and, at the contact of a normal use key, prevents the transversal displacement of the key and the change bar.
