Abstract

Lock with slip and bolt, simplified, being the type in which the slip can be hidden, for opening, by the action of the handle itself coupled to a nut that performs the displacement and concealment of said slip, or by a lever-rocker activated by the key of the lock itself, which key in turn performs the function of operating the bolt in combination with a chime arranged to be displaced orthogonally with respect to the displacement of the bolt itself; with the particularity that the lever-rocker pivots on a pivot provided in the part that is part of bolt consisting of the rod of the ridge with a guided plate, which is pushed by the corresponding end of the rocker-lever or by the own nut, against the action of a spring that tends to keep the slip outward, is essentially characterized in that the mentioned nut is constituted by a flat body provided with a square section hole for the passage and coupling of the end of the actuating handle, the which nut has a slightly arched extension with its straight internal edge, this song being attached to the guided plate of the slip stem, so that in the turn of the handle, turn the nut and move to the ridge, hiding it; having provided another small extension of the own nut, opposite to the arched extension, whose prolongation ends at a pointed end where it is retained at the end of a spring retained against a small stop at its other end, which spring maintains constantly in normal position the nut, being retained against a stop provided in the lock itself, so that in the forced turn of the nut by the handle, that forces the spring to be compressed and characterized because the bell is composed of a rectangular body completely flat and of little thickness, which is guided by its longitudinal edges, between two stops provided in the casing of the lock, while on the upper area of the own flat body of the bell, corresponding to the opposite edge, there is a projection that it constitutes a tooth for blocking the piece that is part of the bolt, when it is outside the rpo of the lock, presenting an opposite and external protrusion to the aforementioned tooth constituting a stop and guide for an expansion spring that tends to keep the bell in its position closer to the eye of the lock and having also provided that one of the guide stops of the bell-tower present a small rectangular and upper projection that is housed in a longitudinal groove made in the part that is part of the bolt, serving as a guide in the displacement of this.
