Definitions

• the invention relates to the field of false walls (false ceilings, false walls).
• a false wall traditionally includes:
• a rail fastened to a wall (wall or ceiling) of a room this rail being generally formed by a succession of abutting rail profiles, optionally secured to each other by means of fishplates or, in the corners, brackets,
• the arm is provided with a groove for fastening an edge of the spear-shaped web.
• the assembly of the tablecloth is manual; to allow the passage of the fingers of the operator or tool and thus allow the attachment of the edge of the spear-shaped web, it is known to provide 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 on the rail, by shifting the groove relative to a wing fixing the rail on the adjacent wall, cf. eg. FR 2 811 693 (NEWMAT) or its US equivalent US 2002/194802.
• This solution has the advantage of facilitating the mounting of the web.
• this solution is not without inconvenience. Indeed, once the web mounted, the space between the adjacent wall and the groove remains and creates a vacuum clearly visible by the shadow of the edge of the web projected on the wall.
• a first objective is therefore to improve the aesthetics of the false walls, at least in the vicinity of their edges.
• a second objective is to allow easy assembly of the sheet.
• a smooth wall false with stretched flexible sheet comprising a smooth section defining an outer wing for fixing the rail on a wall, an internal groove provided with a shoulder for fixing the web, and an outer groove formed between the inner groove and the outer flange, the rail further comprising an integrated lighting system housed in the outer groove.
• the lighting makes it possible to remove the shadow of the sheet and improves the aesthetics of the false wall, at least in the vicinity of the edge of the sheet, without however affecting the assembly of the sheet.
• the lighting system comprises a row of light-emitting diodes
• the outer groove has a bottom on which the light-emitting diodes are mounted
• the boom comprises an attached diffuser which closes the outer groove
• the external groove is delimited laterally by an external wall extending in the extension of the outer wing and a wall opposite internal separating the outer groove from the inner groove, 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 groove;
• the diffuser is provided with claws adapted to cooperate by snapping with grooves dug in the walls of the outer groove;
• the diffuser is made of a translucent material.
• a false wall comprising a rail as shown above, and a flexible stretched sheet fixed in the inner groove of the rail.
• a false ceiling comprising a rail as shown above, and a stretched flexible sheet fixed in the inner groove of the rail.
• Figure 1 is a sectional view showing a smooth equipped with an integrated lighting system, shown with a stretched web secured in an internal groove of the bar, with an inset detail on an enlarged scale;
• Figure 2 is an exploded view of the beam, showing the smooth section, the lighting system in the form of a strip of diodes, and the diffuser, with inserts two details on an enlarged scale.
• a false wall 1 (including a false wall or a false ceiling) for covering a wall (such as, respectively, a wall or ceiling) of a room.
• the false wall 1 is a false ceiling, intended to cover a ceiling 2.
• the false wall 1 comprises a smooth 3 forming a frame which surrounds the ceiling 2 at the junction with a wall 4 adjacent, and a flexible stretched web 5, fixed on the smooth 3 inside the frame thus formed.
• the beam 3 comprises a profile 6 of smooth made of a plastic material (for example PVC) or, preferably, aluminum or an aluminum alloy.
• the profile 6 of smooth is for example manufactured by extrusion.
• the profile 6 smooth defines an outer flange 7 for fixing the smooth 3 on the wall 4 adjacent the junction with the ceiling 2.
• the outer flange 7 has an outer face 8 through which the outer flange 7 is applied against the adjacent wall 4, and an opposite inner face 9. In the illustrated mounting example, the outer flange 7 extends substantially vertically.
• the smooth section 6 is fixed on the adjacent wall 4 by means for example of screws 10 which are caught in holes 11 formed in the adjacent wall 4, through holes 12 formed in the outer flange 7. Although this is not shown, this fixing is preferably carried out by means of expansion plugs mounted in the holes 11, in which the threads of the screws 10 are taken.
• the rail section 6 defines a rail 13 for mounting by sliding of a fishplate or a square to allow the joining by abutment of two profiles 6 smooth adjacent coplanar or, respectively, at right angles.
• the profile 6 of smooth has a core 14 which protrudes substantially at right angles from the inner face 9.
• the core 14 extends substantially horizontally.
• the rail section 6 comprises an internal wing 15 which extends at right angles to the web 14, parallel to the outer wing 7 and up to a lower end thereof.
• the inner wing 15 ends, downwards, by a flange 16 rounded.
• Smooth profile 6 defines, between outer flange 7 and inner flange 15, two adjacent grooves, namely an internal groove 17 on the side of the inner flange 15, and an outer groove 18 on the side of the flange. 7, formed between it and the internal groove 17.
• the external groove 18 is delimited laterally:
• the walls 19, 20 have substantially the same height, while the inner flange 15 is substantially higher and extends downwardly beyond respective edges 21, 22 of FIG. end of the walls 19, 20.
• the inner wall 20 has, on its end edge 22, an angled return 23 forming a shoulder for attaching an outer edge 24 in the form of a harpoon of the stretched web 5, this harpoon 24 being housed in the internal groove 17, while the ply 5 bears against the inner flange 15 and is stretched at right angles to the flange 16 rounded.
• the beam 3 further comprises an integrated lighting system 25 housed in the external groove 18.
• This integrated lighting system comprises for example a row of electroluminescent diodes 26.
• the diodes 26 are mounted on a bottom 27 of the outer groove 18, formed by the web 14 horizontal.
• the diodes 26 are formed on a strip 28 (possibly flexible) fixed on the bottom 27 of the groove 18 by gluing (or other equivalent means), as illustrated in FIG. 2.
• the diodes 26 are oriented so as to illuminate downwards towards the opening of the outer groove 18 defined between the end edges 21, 22 of the walls 19, 20.
• diodes 26 in particular between 30 and 160 diodes per meter
• the color of the diodes (monochromatic, typically blue, red or green, or white, or tri-color red-green-blue with color dimmer).
• the arm 3 further comprises a diffuser 29 attached which closes the groove 18 external.
• This diffuser 29, whose function is to make diffuse the point light of the diodes 26, is preferably made of a translucent material such as a polystyrene or polycarbonate having undergone a surface treatment (such as sanding) or in the mass (for example by adding pigments or inclusions ).
• This diffuser 29 is for example fixed astride the edges 21, 22 end of the walls 19, 20 of the groove 18, preferably by means of removable fastening means. More specifically, according to a preferred embodiment illustrated in the detail box of Figure 1, the diffuser 29 is provided with claws 30 projecting from a face 31 upper, adapted to cooperate by snapping with grooves 32 dug in them. walls 19, 20.
• the diffuser 29 extends laterally inwardly beyond the inner wall. It has in fact an inner end section or beveled flap 33 which, together with the inner flange 15, forms, in line with the internal groove 17, a slot 34 of small width through which the ply 5 extends. This results in a decrease in the risk of harpoon stall 24.
• the assembly of the arm 3 is simple. It is described in the case (illustrated) of a false ceiling.
• the strip 28 of diodes can be equipped with integrated wiring that then just connect to a transformer connected to the mains and delivering a low DC voltage (typically 12V, 24V or 48V).
• a low DC voltage typically 12V, 24V or 48V.
• the flexible ply 5 is hung by introducing its inner edge into the internal groove 17, the harpoon 24 coming to hook on the shoulder 23.
• the ply 5 is then put under tension (for example thermally), and is applied substantially at right angles to the flange 16 rounded of the inner flange 15.
• the diffuser 29 is mounted to close off the external groove 18.
• the flap 33 partially covers the internal groove 17 in the vicinity of the ply 5, the attachment is thus secured.
• the space between the inner flange 15 and the adjacent wall 4 remains sufficient to allow easy mounting of the ply 5 manually (possibly without tools).
