Abstract

Installation of improved blinds of slats, which being of the type that are constituted by a series of metal sheets convex section having an anterior edge curved inward and a rear edge beaded out and are attached to ribbons so that they overlap reciprocally in the closed position, it is essentially characterized in that in the fringed margin on the edge of each sheet there is embedded a slat of elastomeric material that projects from the fringed margin of each slat and extends on the external side of the section, deviated inwards, of the central part of the respective slat, all arranged to form a set of metal slats hingedly joined to guide belts, on their front part, while at their rear longitudinal edge they are, to a traction belt, so less, fixed to a winding tree, on which it is rollable, taking into account that at least one of the sliding surfaces of the articulated joining points between the longitudinal edge of the slats and the traction tape is made of synthetic material, while one of the mentioned longitudinal edges that is folded into a border is surrounded by an eyelet extending through the web. The slit made in the slats and is fixed to the traction belt, it being provided that each eyelet embraces a strip of metal sheet fixed to the traction belt, configured in the form of a staple, also embracing a strip of synthetic material that is it applies against the inner wall of said sheet metal staple and the area or tract of the traction tape facing towards said sheet metal staple, the strip of which has laterally extending ridges protruding with respect to the staple and applying towards or away from the staple. Against its front surfaces, each eyelet of a strip of sheet metal fixed to the traction tape, configured in the form of a staple, can be included, in which case a sleeve of synthetic material is applied, which has a groove extended spirally in longitudinal direction around the longitudinal edge folded in edge of the slats, in the area of the eyelet, or be these of synthetic material, remaining fixed to the traction tape by means of metal tabs disposed in the said traction straps, it being also provided for the fact that each eyelet extends partially protruding through a slot cut in the traction tape and has a substantially circular cross-sectional configuration, in which case it opens on the side facing the pulling tape and has on both sides of the opening thickened in the form of marginal thickenings with a groove open to the outside and extending over the entire longitudinal extension, in whose groove the cut tabs of the pulling tape are attached.
