IMPROVEMENTS IN THE CONSTRUCTION AND ASSEMBLY OF PICAPORTES OF AUTOMATIC CLOSURE AND OPERATION BY POMOS, WITH LOCK IN THE EXTERNAL POMO AND MECHANISM OF CONDEMNATION IN THE INTERNAL, where the immobilization and replacement of the voluntary movement of the shank carrying the grimace is only done with a mechanism located before the inner end of the tang of said knob of the interior face of the door, characterized by the combination of said stem that in the region corresponding to this mechanism is smooth on its surfaces, with the tang of the rear knob that on its edge internal has a cylindrical and grooved narrowing, a plate with circular central hole to adapt with slippage to the external diameter of the aforementioned spike and provided on its circular outer perimeter of four squares of them two long and two short, a plate whose central hole presents a straight section that prevents its rotation in the shank and provided with notches in its periphery, a washer of alamb elastic resizable to the groove of the spike, a quadrangular central hole plate adaptable on the stem and equipped on its surface with four diametrically opposed pointy protrusions with equal grooves and two likewise opposite with straight edges parallel to each other, a conical spring and a maintenance bridge plate fastened on the steel rear face of the immediate shield.
