Abstract

Mechanisms for the assembly of louvres in adjustable fixed shutters, of the type that presents a rectangular frame of metallic profile, depending on the support of a series of slats parallel to each other, with their ends mounted on rotating platforms on two opposite sides of the frame, governed by means of a set of rules and displaceable connecting rods, operable by a toothed sector and a control wheel, each slat being a flat hollow profile, with its edges coinciding with the adjacent slats in their two extreme positions, characterized by the fact of understanding a nexus of uncoupling unión between the ends of the slats and the respective platforms in which they are assembled, constituted by a core fitted under pressure inside each end of the slats, integrating an assembly that is affected by a slot that, crossing transversally the core, has access to the outside by the wall of the slat, and in which slot is susceptible to house a laminar skate secured to the rotating platform, and establishing a retentive disposition by a spring te its laminar retention profiled in the thickness of the skate itself, projecting with respect to one of the faces thereof, feasible to be retained in a corresponding internal housing of the core when the skate is inserted into the slot, the housing being directly communicated with the outside to allow its action on it to release the spring.
