Abstract

Automatic electric strike for doors, of the type which, mounted superimposed on the fixed frame of a door fitted with a slip lock, have a pivoting lever for locking the articulated latch of the strike on which the lock slips. Of the door, which pivoting lever is urged by a spring to assume a locking position, maintained by means of a ratchet in turn urged by another spring which tends to keep it in the locking position of the locking pivoting lever, on which pusher means related to the latch of the strike are constantly applied, which pusher means are only capable of acting once the pawl has been moved from its locking position of the locking lever of the lock, by the instantaneous activation of an electromagnet that releases the pivoting lever, which remains in a position to allow the opening of the articulated tiller of the strike, overcoming the action of a spring positioner thereof, by the thrust exerted by the slip of the door lock in the act of opening it, characterized in that the pusher means are constituted by the association of a a telescopic element and a sliding element, the first element being located in a double rectilinear housing provided in the hinged latch of the strike, which housing has its axis parallel to the axis of the lock of the door lock and perpendicular to the axis of articulation of the door. Said latch of the striker, while the second element is mounted in a through guide arranged in the striker box, which through guide also has its axis parallel to the axis of said lock slip and perpendicular to said articulation axis of the latch of the striker. Strike, the telescopic composite element being constituted by a pivot with an a widened end that runs inside a blind tubular body with intercalation of a compression spring, so that the pivot protrudes from the end of the double housing facing the edge of the bevel of the door lock slip and the blind tubular body makes it, with its blind end of blunt configuration, by the end of the double housing facing the sliding element disposed in the through guide, which, in turn, comprises a wide base or flange for the application of the blunt end of the blind tubular body, a sliding portion by said through guide and an attack tip to a side of the locking toggle lever.
