Abstract

Key lock, which being of the type that involve rotating wheels provided on its periphery of signs for the establishment of the key or combination that makes feasible the positioning of the strike to retain the latch in question; essentially it is characterized in that each of the wheels rotate in a bushing inserted with relative clearance in a shaft stably maintained between two bridges 4e the support housing of the mechanism having provided that such bushes have laterally a cylindrical shoulder with a faceting that flush with the surface lateral of such shells, existing in points diametrically opposed to each other of these. Last and in the line of conjunction with the alluded ridges at least two teeth s that selectively mesh with a kind of pinion carved in the periphery of the axial bore of each wheel, with the particularity the bearing axis thereof to be able to move linearly to a certain extent, against the action of a helical expansion spring, all this by the manual impulse of a trigger that, mounted on the axis itself, emerges. Of the aforesaid casing through a window made in its rear face, whose casing, in turn, involves tilting at the request of another helical expansion spring, a plate that acts as a strike as it emerges permanently and centrally by the front of said casing, said supporting plate being windows where only the casters partially and independently emerge to face elastic tabs that act as ratchet nails against the lateral surface of the casters.
