Abstract

Automatic lock for locks perfected, which is especially applicable in security installations, as a means of blocking access doors to them, is essentially characterized by a built-in module in the frame of a door and a lockable recessed on the door itself, the built-in module incorporating an electronic-electromechanical assembly defined by an electromagnet of a mobile assembly, whose movable core acts as the power arm of an articulated lever which, in turn, is capable of displacing a new lever in l shape, having a turning axis at the end of one of its branches, its other end at the base of a milling bushing embedded in a locking bolt of the door, whose pin is likely to emerge from the recessed module under electric power of the electromagnet, and being, furthermore, subjected to the permanent action of a coaxial recuperating spring with the, the recessed module is provided with signaling means of its operating state and an activation/deactivation system commanded by optical card, key or security key, it being provided that the door strike has a recess capable of accommodating the module pin recessed, in whose cavity the end of a lever is positioned that activates a microswitch provided as a means of commutation of the assembly and with the particularity that the striker is provided with a magnetite which, in the closed door position, is confronted with a switch the magnetic circuit is provided in an electronic circuit that feeds the coil of the aforementioned electromagnet and with the particularity that the electronic circuit includes means for reducing the energy consumed by the electromagnet.
