Abstract: A cylinder and key lock mechanism is unlocked when a specific combination of rotation angles of dialer groups, each constituted by one internal dialer disc and by one external dialer ring coupled through teeth, is dialed through rotation of the key having a formed cipher. A security mechanism, being part of the key and driven by the insertion of the key into the cylinder, enables re-programming. When unlocked and with re-programming enabled, re-programming is possible where the inner dialer discs are decoupled from the respective outer dialer rings, the key can be rotated driving only the inner dialer discs and extracted leaving the system in a re-programming configuration. A new key having a different cipher can be inserted and the system exited re-programming with a different coupling between the inner dialer discs and the respective outer dialer rings so that they couple with the new key cipher.

Abstract: A lock device for sliding gates has a harpoon-type bolt element whose head enters a cavity of a keeper from a shaped hole, and is pushed inside a sleeve by a roto-translation that is controlled by a cam and tappet coupling until the system is locked Reverse motion is prevented by engagement between the anchor of a solenoid and an elongated cavity on the surface of the bolt shaft, however allowing the bolt to tolerate axial displacements from thermal changes or settlements. An unlock control logic allows release of the engagement via a European profile lock cylinder, a mechanical control remotely operated through a Bowden wire, or an electrically controlled solenoid. The control logic ensures the system operation follows the correct direction of motion of a cyclic state machine, to provide proper synchronization with the operation of the gate automation.
