ROLLING BLINDS

OBJECT OF THE INVENTION

 5

The present invention reveals a roller shutter blind that allows optimal shaft winding and gives it a visual and ventilation feature, since by presenting a plurality of perforations allows us maximum vision from the inside to the outside.

BACKGROUND OF THE INVENTION 10

The state of the art used in the formation of closures for openings of buildings incorporates roller blinds provided with slats mounted so that they are wound in a drum arranged in a drawer in the shape of a parallelepiped or a work space that is arranged above the opening of the window, and under the enclosure, or simply is the closing of a hollow without carpentry.

The louvers of the blind must have an easy adaptability to the drum and the roll in formation. In addition, the protection required for this type of closure, must offer great security against the actions of force derived from inclement weather or 20 from the violence of people, so metal slats are used.

Thus, in the utility model U 205106 a blind slat formed with a prolonged curved laminar body with a hook edge on one of its major sides and with an adaptation edge on the opposite side that includes two curved branches is recognized, one of which includes a convex flange that collaborates with the curved end of the opposite branch to limit the reception opening of the engagement edge. For the same purpose, although of a different configuration, the extruded slat shown in the utility model U250793, also warped, has an angularly oriented coupling edge with respect to the vertical axis of the slat and a receiving edge formed in U. 30

Although both models contribute to the closing of the openings to which they have been destined, they do not offer a great compactness in the roll formed with the winding of the blind panel, given the configuration of the slats that make up the blind panel; nor with its use is

obtains the security required against violent actions derived from storms or people, because there is a great slack in the crimp between the slats.

Document DE-A-2505682 discloses a profiled element adapted to be joined in an articulated manner with other profiled elements respectively adjacent to constitute a roller shutter, and having a front wall and a rear wall that are mutually separated and between which there is at least one cavity in which an opening is made in a wall and in which a heat-insulating material is arranged.

This document describes a profile of roller blinds, in particular for doors, windows and the like. This roller blind profile can include cover elements on its two open front faces or a rigid foam bar is inserted into the cavity. It is also described that the narrow longitudinal faces of the rigid foam bar are provided with a profile presenting the joint mechanism with which the profiles can be joined to constitute a roller blind.

In a special embodiment, a roller blind profile with a top and bottom joint mechanism is described, which completely surrounds a rigid foam core. It is also explained that a recess could be left in a wall of this profile of 20 heat-resistant roller blind, which means that this part of the wall would be missing along the whole profile of the roller blind and that the rigid foam core would be visible in The inside of the roller blind profile.

In US-A-4536929 a roller shutter is described which has 25 improved thermal insulation properties and whose cavities are filled with foam. The roller blind profile has grooved openings in a wall to improve the mechanical stability of the roller blind profile. It is also explained that in the cavities of the roller blind a foamed polymeric material is introduced, for example polyurethane, it will decisively improve the heating properties of the profile of the roller blind.

US-A-46298982 describes a profiled element adapted to articulately join with other profiled elements respectively adjacent to

constitute a roller shutter, and which has a front wall and a rear wall that are mutually separate and between which there is at least one cavity. Inside the cavity an insulating material is introduced which has to improve the thermal insulation properties of the profiled element or of the roller blind formed with it.

The blind of the present invention allows an optimal axis winding and gives it a visual and ventilation particularity, since being perforated allows us the maximum view from the inside to the outside and prevents us from being seen from the outside thanks to its outer part is lower than the inner part.

It is rolled on an axis, in its raised position it leaves the entire gap open, in its lowered position it closes the entire gap like a traditional blind and in its intermediate position it allows us ventilation, vision and privacy.

DESCRIPTION OF THE DRAWINGS 15

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of the practical embodiment thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

DESCRIPTION OF THE INVENTION

The present invention reveals a roller blind with characteristics that give it novelty with respect to the state of the art known. The object of the present invention lies in a slat of the type consisting of profiles that are successively coupled to form a roller blind.

In view of these figures, it can be seen how the louver for blinds of the invention, like any conventional metal, aluminum slat, is constituted by a flat, slightly arched tubular body (1) to facilitate its winding, especially in its face internal, in whose lower edge a wide groove (2) of variable mouth is defined, for articulated joint between slats that allows the insertion of the following slat, with the collaboration of a hook-like fin (3) established in its upper edge and provided with a plurality of ventilation-aeration perforations (4) that allow a certain illumination of the cabin protected by the blind in a situation of partial closure thereof, in addition the internal configuration allows a maximum view from the inside to the outside, of such that a person is not seen since the outer part is lower than the inner part.

The blind is manufactured with extruded aluminum slats of at least 27 mm of coverage 20 by at least 10 mm of nominal thickness. With ventilation-aeration dies of at least 80 mm. Due to its select design, it allows an optimal winding on a 60 mm axis.

 The profile is made of aluminum in a magnesium-silicon alloy (6063 T5), due to its great ease of extrusion, presenting adequate mechanical characteristics, a correct surface appearance and good coloring. The aluminum profile is designed to control ventilation, regulate the exterior light from the maximum brightness to the dim light until the desired privacy is achieved.

It is rolled on an axis, in its "raised blind" position it leaves the entire gap open, in 30 its "lowered blind" position closes the entire gap like a traditional blind and in its intermediate position allows us ventilation, vision and privacy.
