Abstract

Improvements in the construction of security locks, characterized by the fact that a lock is made whose body has, in mutual opposition, two cylindrical cavities, one of them destined to house a security key lock, and another to contain a disposition related to an external element of manual operation and in permanent coupling with a drive ring, of a single head, located between the aforementioned cylinder and the arrangement, while this cylinder has no coupling relationship with said ring, this disposition being used to facilitate the actuation directly from the latch of the lock, said arrangement being constituted by a tubular body, joined to an external knob, inside which is danced located a full cylindrical that is pushed into the lock by a spring also placed inside the tubular body , of node that said piece has the ability to realign displacement They are longitudinal within a space limited by a transverse pin, applied between elongated openings of the part itself and which, at the same time, makes the tubular body integral with the drag ring, only so that the actuation of this ring, by means of the key applied to the cylinder, it is only feasible after coupling it with the reference arrangement, for which purpose the cylindrical part of the latter has on its inner front a slot suitable for the insertion of the end of the key exceeding the bowler, which is achieved by rotating the same, said end applied against said front face of the cylindrical part, overcoming the opposition of the spring, it is enough that, at a given moment, there is a coincidence between the key and the said groove. that piece, in which circumstance the piece, under the thrust of the spring, moves forward causing the penetration into it of said end of the key, which thereby coupling the latter with the direct drive arrangement and, therefore, with the drive ring, allowing activation of the lock latch.
