Abstract: Closing latch modular mechanism includes a mechanism casing, a latch with a bevelled surface and a longitudinal surface parallel to the plane of the door, a support, a rotation shaft, an anti-rotation device, a rotatory lever carrying the anti-rotation device, a carriage that is longitudinally displaceable parallel to the plane of the door and a mechanism for actuating the carriage. The latch (2) is installed in the support by the rotation shaft and has a receptacle of semicircular cross-section elongated tangentially at its ends. The receptacle is parallel to the rotation shaft and is situated in its rear surface at a distance from the plane of the door that is suitably greater than the distance of the rotation shaft, and in opposition to the rotation shaft (4).

Abstract: Pushing device for the emerging of the bolt in locks, characterized in that the handle axis (1) has a coaxial lever (8), coupled rotationally, which turns along with it in the conventional direction of opening, being equipped with an independent turning in the opposite direction, or anti-opening turning, whose lever (8) has a peripheral lug (8a) which is applied, in relation to the anti-opening turning, against a fin (9a) of the rocker (9), mounted spring-loaded with a projection (9b) applied against a heel (10a), belonging to a counter-rocker (10), having a front piece (10b) applied against a transverse lug (6b) of the latch plate (6), there being a rotating rod (11) mounted with a free turning coaxially with the rocker (9), having arms, a rocker (11a), and a bolt (11b), rotationally spaced out by an angle preferably less than that needed to simultaneously make contact with the fin (9a) of the rocker (9) in the state of rest and with the back of the bolt (3) in retracted state.
