DESCRIPTION

Illuminated profile for a false tensioned wall, and false tensioned wall equipped with said profile.

The invention relates to the field of false walls (false ceilings, false walls).

A false wall traditionally comprises:

- a profile fixed to a wall (wall or ceiling) of a room, this profile being generally formed by a succession of spliced rail profiles, eventually mutually joined by means of fish plates or, at the angles, of squares,

- a flexible tensioned fabric, fixed on the profile.

According to a particular technique commonly used, the profile is provided with a throat for hooking an edge the harpoon-shaped fabric

The fabric assembly is manual; in order to allow the fingers of the operator or a tool to pass and thus allow the hooking of the edge of the harpoon-shaped fabric, it is known to leave a space between the throat and the adjacent wall (typically the wall in the case of a stretch ceiling). This space can be formed directly in the profile, by displacement of the throat in relation to a fixing wing of the profile on the adjacent wall, see for example document FR 2,811,693 (NEWMAT) or its American equivalent US 2002/194802.

This solution has the advantage of facilitating the assembly of the fabric. However, this solution is not without problems. Indeed, once the fabric is mounted, the space provided between the adjacent wall and the throat remains and creates a fairly visible void by the shadow of the edge of the fabric projected on the wall.

It is known to use this space to form a suspension area of hooks for the suspension of frames or other objects, as proposed by EP 388 925 cited above (see Figure 15 and the corresponding passage of the description).

However, even in this application, the shadow generated by the free space between the edge of the fabric and the adjacent wall impairs the overall aesthetics of the false wall.

To try to alleviate this aesthetic defect, it is known to cover this space by means of an added finishing cover, which establishes a connection between the support edge of the fabric and the wall, as proposed by EP 388 925 mentioned above. (See in particular Figure 11 and the corresponding passage in the description).

But such a cover does not fully compensate for the aesthetic defect induced by the presence of the space between the adjacent wall and the edge of the fabric. First, the color of the lid (usually hard plastic) may have shades in relation to the color of the fabric (usually flexible plastic or coated fabric). Secondly, there is a gap between the inner edge of the lid and the edge of the fabric, this gap being visible and therefore damaging to the overall aesthetics of the false wall in the joint with the adjacent wall.

Document GB 1 150 225 A describes a rail according to the preamble of claim 1.

A first objective is therefore to improve the aesthetics of false walls, at least in the vicinity of their edges.

A second objective is to allow easy assembly of the fabric.

First, a profile for a false wall with flexible tensioned fabric according to claim 1 is proposed.

In this way, the lighting allows the shade of the fabric to disappear and improves the aesthetics of the false wall, at least in the proximity of the edge of the fabric, without however damaging the assembly of the fabric.

Various additional features may be provided, alone or in combination:

- the lighting system comprises a row of electroluminescent diodes;

- the external throat has a bottom on which the electroluminescent diodes are mounted;

- the external throat is laterally delimited by an external wall that extends in the extension of the external wing and an opposite internal wall that separates the external throat from the internal throat, and the diffuser is fixed on the end edges of the walls;

- the diffuser is provided with removable fixing means on the walls of the external throat;

- the diffuser is provided with suitable claws to cooperate by crimping with grooved recesses in the walls of the outer throat;

- the diffuser is made of a translucent material.

Secondly, a false wall is proposed comprising a profile as presented above, and a flexible tensioned fabric fixed in the internal throat of the profile.

Thirdly, it is proposed, a false ceiling comprising a profile as presented above, and a flexible tensioned fabric fixed in the internal throat of the profile.

Other objects and advantages of the invention will appear in the light of the description of an embodiment, given below in reference to the accompanying drawings in which:

- Figure 1 is a sectional view showing a profile equipped with an integrated lighting system, represented with a tensioned fabric fixed on an internal throat of the profile, with signage of an enlarged detail;

- Figure 2 is a fragmented view of the profile, showing the profile of the rail, the lighting system in the form of a diode ribbon, and the diffuser, with signage of two details on an enlarged scale.

In figure 1, a false wall 1 (particularly a false wall or a false ceiling) intended to cover a wall (such as, respectively, a wall or a ceiling) of a room is partially represented in section.

In the illustrated example, the false wall 1 is a false ceiling, intended to cover a ceiling 2. In this respect, the false wall 1 comprises a profile 3 that forms a frame surrounding the ceiling 2 at the junction with an adjacent wall 4 , and a tensioned flexible fabric 5, fixed to the profile 3 by the interior of the frame thus formed.

Profile 3 comprises a rail profile 6 made of a plastic material (for example in PVC) or, preferably, aluminum or an aluminum alloy. The rail profile 6 is for example manufactured by extrusion.

The rail profile 6 defines an external wing 7 for fixing the profile 3 on the wall 4 adjacent to the junction with the roof 2. The outer wing 7 has an external surface 8 whereby the outer wing 7 is applied against the wall 4 adjacent, and an opposite internal surface 9. In the illustrated assembly example, the outer wing 7 extends substantially vertically.

The rail profile 6 is fixed on the adjacent wall 4 by means of, for example, screws 10 that are placed in the holes 11 made in the adjacent wall 4, through perforations 12 formed in the outer wing 7. Although it has not been represented, this fixation is preferably carried out by means of expansion plugs mounted in the holes 11, in which the threads of the screws 10 are coupled.

On the side of an upper end of the outer wing 7, the rail profile 6 defines a rail 13 for the sliding mounting of a fish plate or a square designed to allow the splicing of two adjacent coplanar rail profiles 6 or, respectively, at right angles.

On the side of a lower end of the outer wing 7, the rail profile 6 has a core 14 that extends in projection, substantially at right angles, from the inner surface 9. In the illustrated assembly example, the core 14 extends substantially horizontally.

As can be seen in FIG. 2, the rail profile 6 comprises an internal wing 15 which squarely extends from the core 14, parallel to the external wing 7 and beyond a lower end thereof. The inner wing 15 ends, downwards, by a rounded flange 16.

The rail profile 6 defines, between the outer wing 7 and the inner wing 15, two adjacent throats, namely an inner throat 17 on the side of the inner wing 15, and an outer throat 18 on the side of the outer wing 7, provided between it and the internal throat 17.

The outer throat 18 is laterally delimited:

- towards the outside by an external wall 19 extending in the extension of the external wing 7 downwards, from the horizontal soul 14, and

- inwardly by an opposite inner wall 20, which extends downwardly from the horizontal core 14, substantially parallel to the outer wall 19 and the inner wing 15, between them, the inner wall 20 thus separating the outer throat 18 of the internal throat 17.

As can be seen in Figure 1, the walls19, 20 have substantially the same height, while the inner wing 15 is substantially taller and extends downward beyond the respective end edges 21, 22 of the walls 19, twenty.

As illustrated, the inner wall 20 has, at its end edge 22, a square return 23 forming a projection for the engagement of an outer edge 24 in the form of a harpoon of the tensioned fabric 5, this harpoon 24 being housed in the internal throat 17, while the fabric 5 rests against the internal wing 15 and extends at a right angle over the rounded flange 16.

The profile 3 further comprises an integrated lighting system 25, housed in the external throat 18.

This integrated lighting system 25 comprises, for example, a row of electroluminescent diodes 26. In the illustrated example, the diodes 26 are mounted on a bottom 27 of the outer throat 18, formed by the horizontal core 14.

According to a particular embodiment, the diodes 26 are formed by a ribbon 28 (possibly flexible) fixed to the bottom 27 of the throat 18 by gluing (or other equivalent means), as illustrated in Figure 2. The diodes 26 they are oriented so that they illuminate downwards, in the direction of the opening of the outer throat 18 defined between the end edges 21, 22 of the walls 19, 20.

The following parameters of the lighting system 25 can be chosen as required:

- its luminic power (particularly between 3 W / m and 40W / m),

- its luminic density of diodes 26 (particularly between 30 and 160 diodes per meter),

- the color of the diodes (monochromatic, typically blue, red or green, or also white, or trichrome, red-green-blue with color variator).

According to a particular embodiment, illustrated in the figures, the profile 3 further comprises an added diffuser 29 that closes the external throat 18. This diffuser 29, whose function is to diffuse the point light of the diodes 26, is preferably performed in a translucent material such as a polystyrene or a polycarbonate that has undergone a surface treatment (such as a sandblasting) or in the mass (by example by adding pigments or inclusions).

This diffuser 29 is for example fixed on horseback on the end edges 21, 22 of the walls 19, 20 of the outer throat 18, preferably with the aid of removable fixing means. More precisely, according to a preferred embodiment illustrated in the detail marking of Figure 1, the diffuser 29 is provided with protrusive claws 30 on an upper surface 31, suitable for cooperating by crimping with grooves 32 recessed in the walls 19, twenty.

As in the example illustrated in Figure 1, the diffuser 29 extends laterally inwardly beyond the inner wall 20. In fact, it has an internal end section or bevelled breastplate 33 which, together with the internal wing 15, forms, to the right of the internal throat 17, a groove 34 of small width through which the fabric 5 extends. This results in a decrease in the risk of disengagement of the harpoon 24.

Mounting profile 3 is simple. It is described in the case (illustrated) of a false ceiling.

It begins by fixing on the adjacent wall 4 the rail profile 6 pre-equipped with the lighting system 25, at the junction of the adjacent wall 4 with the ceiling 2. This fixing is carried out by means of screws 10 that are screwed into the plugs inserted in the holes 11 provided in the adjacent wall 4, through the perforations 12 made in the outer wing 7.

The electrical connection of the lighting system 25 is then carried out. In this regard, the diode ribbon 28 may be equipped with an integrated wiring that is then sufficient to connect to a transformer connected to the network and that provides a low continuous voltage (typically 12V, 24V or 48V).

Next, the flexible fabric 5 is hooked by inserting its inner edge into the internal throat 17, the harpoon 24 being hooked on the shoulder 23. The fabric 5 is then tensioned (for example thermally), and applied substantially at right angles. on the rounded edge 16 of the inner wing 15.

Once the fabric 5 is tensioned, the diffuser 29 is mounted to cover the external throat 18. The bib 33

partially covers the internal throat 17 in the vicinity of the fabric 5, whose hook is thus

insured.

It only remains to put diodes 26 under tension. The illumination of the profile 3 in the space between the section of tensioned fabric on the inner wing 15 and the adjacent wall 4 eliminates any shade of the fabric 5 on the wall 4

adjacent and thus improves the aesthetics of the false wall 1, at least in the proximity of its outer edge.

In addition, this lighting, which seems indirect once one has moved far enough away from the adjacent wall 4, substantially increases the overall brightness of the room.

The space provided between the inner wing 15 and the adjacent wall 4 is sufficient to allow easy assembly of the fabric 5 manually (possibly without a tool).
