20140183880 | ANTI-SHOCK ELECTROMECHANICAL LOCK - The present invention concerns an electromechanical lock ( | 07-03-2014 |
20130047688 | PROGRAMMABLE CYLINDER LOCK AND KEYS FOR THE OPERATION THEREOF - A programmable cylinder lock includes a stator and a cylindrical rotor mounted therein, having a keyhole and including 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 locking pins, and a change bar slidingly coupled with the followers to keep them engaged with the pins and disengage them therefrom when the bar provides a lock programming position. The bar has projections facing the keyhole, and the use key has corresponding recesses to face the projections when correctly inserted in the lock, whereas the change key has a longitudinal groove extending in a position corresponding to the use key recesses. | 02-28-2013 |
20130036782 | PROGRAMMABLE CYLINDER LOCK HAVING A DEVICE FOR PROTECTION OF THE CODIFICATION, AND THE KEYS FOR THE OPERATION THEREOF - 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. | 02-14-2013 |
20120304717 | PROGRAMMABLE CYLINDER LOCK WHICH DOES NOT REQUIRE A SPECIAL CHANGE KEY - 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. | 12-06-2012 |
20120304716 | PROGRAMMABLE CYLINDER LOCK HAVING A MODIFIED CHANGE POSITION - A lock with a programming device, includes a stator ( | 12-06-2012 |
20120291505 | PROGRAMMABLE CYLINDER LOCK HAVING A HIGH NUMBER OF COMBINATIONS - A programmable cylinder lock includes a stator and a cylindrical rotor, mounted therein for rotation around its own axis and having a keyhole, a number of key followers movable along their own longitudinal and transversal directions, intended to cooperate with a key inserted into the keyhole, a number of locking pins movable along their own longitudinal direction, the key followers and locking pins forming together a number of pairs and having toothings cooperating to define the lock codification, the rotor including a stop bar cooperating with a longitudinal groove of the stator and having projections cooperating with notches of the locking pins to immobilize them when the stop bar engages them, and a change bar slidingly coupled with the key followers to normally keep them engaged with the locking pins and to disengage them therefrom when the change bar provides a lock programming position. | 11-22-2012 |
