Abstract

Perfect lock, which includes a flat face closure latch, not enramped, which is automatically located in the frame with the closure of the door, through a device that includes a non-flat head teton, preferentially spherical, that emerge by the front side of the lock and is displacable to the parallel interior to the closure latch, when it incides against the frame of the door, opening through a moving flap associated with a handle or similar half that moves the latch in address opposite, characterized because the device that relates the teton with the latch is constituted by a lever, equipped with certain flexibility, that rotates at a central point and whose extremes respectively incides into the teton and the latch, trying to situate them in opposite positions, which receives the action of a spring that tends to maintain the teton outside the lock box, and whose flexibility provides a spring of torsion, mounted in the same axis that such lever, whose branches topan with side foliats of this delimiting their maximum opening, coupling the ends in a guide of the closure latch, so that when the teton and the latch must be hidden, moments before the closure or at the opening, said spring of torsion is compressed approaching its branches to allow this situation, accumulating the necessary energy to return to its expanded position once past that instant and as a result that the latch and teton return to occupy contrast positions.
