Definitions

  • the invention relates to the field of false ceilings.
  • the invention relates more particularly to a flexible sheet intended for the production of a false ceiling, said sheet being made up of two superposed canvases and assembled at the periphery on a means of attachment, one of the canvases being solid, the other being openwork.
  • openwork canvas we mean a canvas comprising hollowed-out (or cut-out) zones.
  • the flexible sheet is intended in particular, but not exclusively, for the production of false ceilings offering luminous visual patterns.
  • the false ceilings include a so-called double flexible sheet, made up of two superimposed fabrics, ie arranged one on top of the other, the top fabric being translucent and full, the bottom fabric being opaque and cut (or perforated) according to a given shape (pattern), said sheet being placed under luminous means arranged in the residual space provided between the ceiling and the false ceiling.
  • the invention aims to remedy these problems by proposing a flexible sheet making it possible to produce false ceilings having visual patterns, advantageously bright, clean and can be easily cleaned.
  • the invention proposes a flexible sheet intended for the production of a false ceiling in a room, said sheet being made up of two superposed fabrics and assembled together at their peripheral edge, the one of the canvases being solid, the other being perforated.
  • the flexible web according to the invention is remarkable in that the fabric placed above, which is perforated, has a weight greater than that of the full fabric placed below so that the perforated fabric is kept affixed to the full fabric when the tablecloth is hung on the rail.
  • the top fabric is kept flat on the bottom fabric.
  • the false ceilings produced using a sheet according to the invention offers a rendering of the patterns formed by the openwork fabric. Furthermore, the lower canvas being solid, the cleaning of the web is facilitated.
  • the perforated canvas is opaque.
  • the solid canvas is wholly or partly translucent or transparent.
  • the web is provided with a peripheral attachment means allowing it to be attached to a rail, the perforated fabric and the solid fabric being assembled together on said peripheral attachment means.
  • the fabrics are welded together at the attachment means.
  • one of the fabrics has micro-perforations arranged to form, with the other fabric, an acoustic layer.
  • the invention also relates to a false ceiling comprising a flexible web as described above, fixed taut on at least one rail, the perforated fabric being arranged on the opposite side inside the room in which the false ceiling is arranged.
  • the false ceiling comprises luminous means arranged above the perforated canvas.
  • a false ceiling 1 of the stretched false ceiling type equipped with a flexible sheet 2 according to the invention hung stretched on smooth 3 fixed to the wall walls 4 of a room.
  • the heddles 3 form with the ply 2 a closed structure which is advantageously sealed.
  • the sheet 2 consists of two fabrics 3, 4, advantageously made of polyvinyl chloride, superimposed and assembled at the periphery on a means of attachment 5.
  • the attachment means 5 has the shape of a harpoon 6 which cooperates with the attachment shoulder 7 of the heddles 3 provided for this purpose.
  • the two fabrics 3, 4 are assembled by welding.
  • the two fabrics 3, 4 are firstly assembled together at the periphery, to be secondly fixed to the attachment means 5.
  • the fabrics 3, 4 are fixed independently of each other by means of attachment 5.
  • the assembly of the fabrics 3, 4 between them and the assembly of the fabrics 3, 4 on the means of attachment 5 is carried out by welding.
  • the assembly can of course be achieved by any other known fixing means, such as gluing.
  • the canvas arranged above, ie, on the side opposite the side visible from inside the room, is an openwork canvas, advantageously opaque
  • the canvas arranged below, ie arranged on the side visible from inside the room is a solid canvas, that is to say without a recessed area, advantageously opaque.
  • the figure 2 shows an exploded view of the ply 2.
  • the solid fabric 4 placed under the perforated fabric 3, thus covers the recessed areas 30 of the perforated fabric 3.
  • the full fabric 4 placed below thus ensures the airtightness, dust or other residue.
  • the recessed areas have the shape of squares.
  • the two canvases 3, 4 have been represented on the figure 1 with a slight distance between them, in order to show the number of fabrics constituting the web 2.
  • the two fabrics 3, 4 are however superposed, that is to say in contact with one another.
  • the top fabric has a weight greater than that of the bottom fabric so that when the web 2 is fixed taut on the smooth, the fabric top, in this case the perforated canvas 3, rests on the solid canvas 4.
  • the weight ratio between the perforated canvas 3 and the solid canvas 4 will have to be defined to avoid a bending of the canvas below under the mass of the top canvas.
  • one of the fabrics 3, 4 comprises micro-perforations 40 arranged and distributed so as to form a fabric that acoustically absorbs sound.
  • micro-perforations 40 is meant any perforation having a diameter less than or equal to 2 millimeters.
  • the presence of a micro-perforated canvas has the advantage of significantly increasing the acoustic performance of the structure 1.
  • the micro-perforations 40 are provided on the canvas arranged on the side visible from inside the room, namely, in the example shown, on the full canvas 4.
  • the false ceiling is a luminous false ceiling.
  • light means 8 are arranged above the sheet 2, in the space 9 delimited by the ceiling 10 and the stretched sheet 2. They are fixed on the ceiling 10.
  • the light coming from the luminous means 8 passes through the perforated zones 30 of the opaque canvas above and the parts of the translucent canvas located under the perforated zones 30 and opposite those. ci, thus producing a false ceiling offering visual patterns corresponding to the shape of the openwork areas provided, without the latter being blurred due to the perfect veneer of the canvases 3, 4 between them.
