DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

(7) In view of the aforementioned figures and, in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.

(8) FIG. 1 schematically shows a decorative shade valance that is provided with a pair of fastening systems located on two ends facing each other. The decorative valance is comprised of a front panel 1 of a rectangular shape, a pair of side panels facing each other 2 and joined to the front panel 1, the front panel 1 and the side panels 2, defining an inner housing, a housing in which there is a rotating roller 3 (driven manually or by a motor) to which the band of roller shade or blind is coupled.

(9) Each one of the fastening systems comprises an anchoring element, indicated generally with the reference 4, which has a first coupling region configured to be coupled to a wall or ceiling, a second region provided with coupling means provided for supporting the drive means of the rotating roller 3, and guide means (that are described further on) which are configured to attach one of the side panels of the decorative valance. In the present exemplary embodiment, the anchoring elements 4 are turned such that they attach to a ceiling.

(10) Specifically, the anchoring element 4 is made up of a perforated laminar body defined by a central axis of symmetry E that defines two equal parts, symmetrical to each other, made from a metal material, a first flap 40 having an essentially square shape upon which the first region is arranged and a second flap 41 with an essentially rectangular shape, being folded at a right angle with respect to the first flap 40. The second region, as well as the fastening means, are arranged on this second flap 41. It is worth mentioning that in general the first flap 40 has small dimensions with respect to the second flap 41 of the laminar body. The fact that the anchoring element 4 has two equal, symmetrical parts allows that anchoring element 4 to attach to a ceiling or a wall.

(11) In particular reference to the first region, it has at least one pair of slotted through holes 5 separated from each other that are configured to allow the passage of corresponding screw elements 6, which are provided for attachment to holes made in the wall or ceiling.

(12) It can be seen how the second flap 41, wherein the second region is arranged, has a through hole 7 on one of its faces, around which a plurality of tabs 8 distributed radially around that through hole 7 project outwards. This hole 7 is provided to couple with an end of the rotating roller 3.

(13) With regards to the guide means, they comprise four protrusions 9 in a T shape that project from a plane perpendicular to each one of the sides of the second flap 41 of the anchoring element 4, said protrusions 9 being configured to couple to guides 20 arranged longitudinally along the inner face of each one of the side panels 2 of the decorative valance (see FIGS. 1, 4 and 5).

(14) FIG. 3 shows a second variation of the anchoring element 4 being anchoring element 4 made up of a perforated laminar body defined by a central axis of symmetry E that defines two equal parts, symmetrical to each other, made from a metal material, a first flap 40 having an essentially square shape upon which the first region is arranged and a second flap 41. Said second flap 41 is essentially different from the second flap 41 of FIG. 1 in that it lacks the hole 7, wherein an accessory to couple to the opposite end of the rotating roller 3 is included. Also, it has one pair of slotted through holes 5 separated from each other and protrusions 9 configured to couple to guides 20 arranged longitudinally along the inner face of each one of the side panels 2.

(15) Furthermore, the fastening system is provided with gripping means located in the second region which are configured to keep the anchoring element 4 attached to the side panel of the decorative valance. These gripping means essentially comprise screws 10 that pass through the respective through holes 11, 11 (see FIG. 3) located on the second flap 41, the through holes 11, 11 being located on each one of the corners of that second flap 41.

(16) Finally, FIG. 6 shows a second assembly of a roller shade that comprises a rotating roller 3 located inside the decorative valance, wherein each one of its two ends are supported by means of an anchoring element 4, 4. Each one of the anchoring elements 4, 4 also support a respective side panel 2 and they are turned in order to be attached to a vertical wall, unlike the assembly shown in FIG. 1. In this exemplary embodiment, the rotating roller 3 is designed to be driven by chain.
