Definitions
- the invention relates to the field of false ceilings.
- the invention more particularly relates to a flexible sheet for the realization of a false ceiling, said sheet consisting of two superimposed canvases and assembled peripherally on a hooking means, one of the canvases being full, the other being perforated.
- Openwork fabric means a canvas having recessed areas (or cut).
- the flexible sheet is intended in particular, but not exclusively, to the realization of false ceilings providing bright visual patterns.
- the false ceilings comprise a so-called double ply, consisting of two superimposed canvases, ie arranged one over the other, the top fabric being translucent and solid, the bottom fabric being opaque and cut (or perforated) according to a given form (pattern), said sheet being placed under light means arranged in the residual space between the ceiling and the false ceiling.
- the invention aims to remedy these problems by proposing a flexible sheet to achieve false ceilings with visual patterns, advantageously bright, clean and easy to clean.
- the invention proposes a flexible sheet intended for the realization of a false ceiling in a room, said sheet consisting of two superposed canvases and assembled together at their edge peripheral, one of the canvases being full, the other being perforated.
- the flexible sheet according to the invention is remarkable in that the fabric disposed above, which is perforated, has a weight greater than that of the solid fabric disposed below so that the perforated fabric is maintained affixed to the solid fabric when the tablecloth is hung on the rail.
- the top fabric is kept plated on the canvas underneath.
- the false ceilings made using a web according to the invention provides a rendering of the patterns formed by the open net fabric. Moreover, the lower fabric being full, the cleaning of the tablecloth is facilitated.
- the openwork fabric is opaque.
- the solid fabric is in all or part translucent or transparent.
- the web is provided with a peripheral attachment means for fixing it to a rail, the perforated fabric and the solid fabric being assembled one on the other on said means of attachment device.
- the fabrics are welded together at the attachment means.
- one of the fabrics comprises micro-perforations arranged to form, with the other fabric, an acoustic layer.
- the invention also relates to a false ceiling comprising a flexible sheet as described above, fixed stretched on at least one smooth, the perforated fabric being disposed on the opposite side to the interior of the room in which the false ceiling is arranged .
- the false ceiling comprises light means arranged above the perforated fabric.
- FIG. 1 shows a partial schematic sectional view of a false ceiling equipped with a flexible sheet according to the invention
- FIG. 2 represents an exploded view of the web illustrated in FIG.
- the sheet 2 consists of two webs 3, 4, preferably polyvinyl chloride, superimposed and assembled peripherally on a hooking means 5.
- the hooking means 5 has a harpoon shape 6 which cooperates with the attachment shoulder 7 of the smooth 3 provided for this purpose.
- the two webs 3, 4 are assembled by welding.
- the two webs 3, 4 are assembled firstly between them peripherally, to be secondly fixed by means of hook 5.
- the webs 3, 4 are fixed independently of each other by means of attachment 5.
- the assembly of the webs 3, 4 between them and the assembly of the webs 3, 4 on the attachment means 5 is made by welding.
- the assembly can of course be made by any other known fastening means, such as gluing.
- the fabric disposed above, ie, the opposite side to the visible side from the inside of the room, is a perforated canvas, preferably opaque
- the fabric disposed below, ie disposed on the visible side from the interior of the room is a solid web, that is to say without recessed area, preferably opaque.
- FIG. 2 shows an exploded view of the ply 2.
- the solid fabric 4 disposed under the perforated fabric 3, thus covers the recessed areas 30 of the perforated fabric 3.
- the solid fabric 4 disposed below thus ensures the tightness of the fabric. air, dust or other residues.
- the recessed areas have the shape of squares.
- the two canvases 3, 4 have been shown in FIG. 1 with a slight spacing between them, this in order to show the number of canvases constituting the web 2.
- the two canvases 3, 4 are, however, superimposed, that is, to say in contact with each other.
- the fabric above has a grammage greater than that of the fabric underneath so that when the ply 2 is fixed stretched over the heddles, the fabric from above, in this case the perforated fabric 3, rests on the solid fabric 4.
- the weight ratio between the perforated fabric 3 and the solid fabric 4 must be defined to prevent sagging of the fabric below the mass of the fabric. canvas from above.
- one of the canvases 3, 4 comprises micro-perforations 40 arranged and distributed so as to form a sound absorbing cloth acoustically.
- micro-perforations 40 is meant any perforations having a diameter less than or equal to 2 millimeters.
- the presence of a micro-perforated fabric has the advantage of significantly increasing the acoustic performance of the structure 1.
- the micro-perforations 40 are provided on the fabric disposed on the visible side from inside the room, to know, in the example shown, on the full canvas 4.
- the false ceiling is a false ceiling light.
- light means 8 are arranged above the sheet 2, in the space 9 delimited by the ceiling 10 and the sheet 2 stretched. They are fixed on the ceiling 10.
- the light coming from the light means 8 passes through the perforated zones 30 of the opaque canvas above and the parts of the translucent fabric located under the perforated zones 30 and facing these. ci, thus realizing a false ceiling providing visual patterns corresponding to the shape of the openwork areas provided, without these being blurred because of the perfect veneer of the webs 3, 4 between them.
