Definitions

  • the present invention relates to a dustproof light box intended to be integrated into a false wall, preferably a false ceiling, comprising at least one stretched sheet.
  • False walls including false ceilings, conventionally comprise one or more stringers which are fixed to each of the walls and / or ceiling of a room, and a fabric, for example elastic and generally opaque, which is deformed by tension so that its edges, provided with hooking means, can be fixed to said rails with the aid of these attachment means, taking care to stretch the fabric to provide a beautiful appearance.
  • This fabric is thus stretched parallel to a wall of the room so as to leave a residual space between the wall of said room and said fabric.
  • This residual space also called velum, can accommodate all unsightly equipment such as electrical cables, pipes, etc. Consequently, said fabric makes it possible to mask these equipment but also the imperfections of the walls of the room and to have a uniform and clean visible surface by retaining in particular the dust in this awning.
  • the false wall comprises relief elements comprising non-coplanar adjacent faces, such as boxes, which can be arranged to illuminate the room or for decorative purposes.
  • Light boxes of this type are already known, capable of being integrated into a false ceiling, of generally parallelepipedal shape, comprising a plurality of light sources fixed to the ceiling and situated inside four adjacent non-coplanar vertical faces attached to said ceiling. ceiling and a canvas translucent covering at least the open horizontal bottom face of the light box.
  • the document is particularly known WO 01/20224 which describes a light box intended to be suspended from a ceiling, this light box having profiles on which are stretched webs forming a tubular enclosure in which are housed light sources.
  • the light sources are separated from the lower fabric by an intermediate fabric fixed on a profile provided inside the tubular enclosure.
  • WO 01/20091 describes a light box intended to be attached to other similar boxes to form a suspended ceiling.
  • Each box comprises profiles on which are stretched webs forming a tubular enclosure in which are housed light sources.
  • the lower wall of the tubular enclosure is retractable so as to facilitate access to the light sources.
  • the outline of this bottom wall is delimited by a profile provided inside the tubular enclosure and forming a frame, on either side of which, a fabric can be stretched.
  • the purpose of the present invention is to provide a light box adapted to be easily integrated into a false wall, in particular a flexible sheet, to prevent dust from the rear portion of the light box are visible to preserve a look visible clean and aesthetic said light box, this box integrating visually well to the false ceiling so as to give a homogeneous finished appearance.
  • the present invention relates to a dustproof light box intended to be integrated into a false wall, said light box comprising a plurality of non-coplanar adjacent faces defining a tubular shape, an outer face delimited by the edge of said tubular shape , a plurality of light sources fixed inside the tubular form and a flexible outer sheet covering at least said outer face, a flexible inner sheet disposed inside the tubular form between the light sources and the outer sheet and allowing substantially sealing the outer ply of said light sources.
  • Said light box is remarkable in that it comprises external rails forming a peripheral frame disposed outside the tubular shape and having engagement means adapted to receive and hold the outer sheet and the flexible sheet so as to keep them tense.
  • the interior of the light box according to the invention is thus completely concealed in view which allows both the dust and the structure of the light box not to be visible.
  • the light box can easily be integrated into a false ceiling and in particular to a false ceiling comprising at least one stretched sheet which will be maintained at the same level as the outer ply of the light box, reinforcing the visual homogeneity of the false ceiling comprising the integrated light box.
  • the outer ply consists of a translucent fabric obtained from polymeric materials. It may also be provided with a peripheral edge forming a harpoon adapted to be inserted into said outer rails.
  • the inner sheet preferably covers all the tubular shape.
  • the box according to the invention is of parallelepiped shape and the adjacent non-coplanar faces, which are therefore four in number, are made of translucent material.
  • the adjacent faces are fixed to one another by means of internal spar-smooth assemblies arranged inside said adjacent faces.
  • the flexible inner ply is translucent or better constituted by a transparent fabric obtained from polymeric materials.
  • the inner sheet and advantageously a peripheral edge forming a harpoon. This harpoon forms a hooking means adapted to cooperate with said inner smooth and located right of the false wall.
  • the light box comprises longitudinal members forming a peripheral frame fixed to the end of the four adjacent faces opposite to the outer face and inside the tubular shape.
  • the light box may also comprise internal rails forming a peripheral frame disposed inside the tubular shape under said longitudinal members and being able to cooperate with the harpoon to keep the inner ply taut.
  • outer rails and the inner smooth are at the same level, arranged facing each other, on either side of the adjacent faces.
  • a dust-proof light box integrated in a suspended false ceiling will be described; however, the light box can obviously be used in a false wall.
  • the light box 1 is intended to be integrated with a false wall 2 false ceiling type, disposed in a room 3 having vertical walls 4 and a ceiling 5.
  • Ce ce plafond 2 comprises, on the one hand, a peripheral frame fixed in the upper part of the walls 4 of the room 3, this frame being formed by a rail 6 itself consisting of abutting profiles, and on the other hand, a flexible sheet 7 stretched at a distance of inside this frame.
  • This flexible sheet 7 is most often made of a fabric of polymeric materials provided with a peripheral edge forming a harpoon 8. Said flexible sheet 7 is held taut because of the hooking on the sill 4 of said harpoon 8, along Ceiling 5 of the room 3 so as to leave a velum 9 located between said ceiling 5 and said flexible sheet 7.
  • the light box 1 comprises a plurality of non-coplanar vertical adjacent faces 10 defining a tubular shape 11, a bottom panel 12 closing at least partially one of the ends of the tubular form 11 and an outer face 13 delimited by the edge of the other end of said tubular form 11.
  • the light box 1 according to the invention is of parallelepipedal shape and has four adjacent faces 10 in the general shape of a rectangle and the outer face 13 is completely open.
  • Said light box 1 is arranged at least partially in relief, which means that a portion of the tubular form 11 projects from the false ceiling 2, that the bottom panel 12 is located in the awning 9 and that the outer face 13 belongs to said projecting portion.
  • the light box 1 also comprises a plurality of light sources 14 fixed inside the tubular form 11 advantageously on the bottom panel 12 and consist for example of discharge tubes.
  • the light box 1 comprises unrepresented fastening means for securing and preferably maintain in the spaced position the light box 1 on the ceiling 5 of the room 3.
  • These fixing means comprise for example hooks connected to the ceiling by metal chains.
  • the light box 1 also comprises longitudinal members 15 forming a peripheral frame fixed at the top of the four adjacent faces 10 inside the tubular form 11 and allowing, on the one hand, the assembly of said adjacent faces 10 with each other and with the bottom panel 12 and, on the other hand, the fixing of internal stringers 16 also forming a peripheral frame disposed inside the tubular form 11 under said longitudinal members 15.
  • the light box 1 further comprises external rails 17 forming a peripheral frame disposed outside the tubular form 11. These outer rails 17 define engagement means in which webs can to be inserted and blocked
  • the flexible sheet 7 of the false ceiling 2 must have an orifice whose shape is similar to that of a horizontal section of said light box 1 and which is provided with a peripheral edge forming a harpoon 8 advantageously identical to that cooperating with the smooth 6. Said flexible sheet 7 is held taut around said light box 1 due to the attachment in the engagement means of the outer rails 17 of said harpoon 8.
  • the light box 1 also comprises a taut flexible outer ply 18 covering at least the outer face 13 of the projecting portion of the tubular form 11.
  • this outer ply 18 which consists of a translucent fabric obtained from polymeric materials provided with a peripheral edge forming a harpoon 19 advantageously identical to those of the flexible ply 7, also covers the portion adjacent faces 10 projecting from the false ceiling 2. This outer ply 18 is then maintained stretched around the projecting portion of said light box 1 due to the attachment in the engagement means of the outer rails 17 of said harpoon 19.
  • the outer rails 17 make it possible to keep both the outer ply 18 with the harpoon 19 and the flexible ply 7 with the harpoon 8 taut.
  • the light box 1 comprises an internal sheet 20 flexible tension disposed within the adjacent faces 10 between the light sources 14 and the outer ply 18.
  • this inner ply 20 consists of a transparent fabric obtained from polymeric materials provided with a peripheral edge forming a harpoon 21 advantageously identical to that of the flexible ply 7. This inner ply 20 is then maintained taut inside the adjacent faces 10 due to the hooking on the inner smooths 16 of said harpoon 21.
  • the adjacent faces 10 are made of translucent material of the polymer or glass type.
  • the preferred polymers for the production of these adjacent faces 10 there will be mentioned more particularly polymethyl methacrylate well known to the skilled person under the trade names of Plexiglas, Altuglas but also under the names of acrylic plastic, Perspex, Limacryl, Vitroflex, Altuglas, Metacrilat or Lucite.
  • the spars 15, the inner smooth 16 and the outer smooth 17 are preferably extruded profiles made of an aluminum type light alloy whose inner grooves define the engagement means.
  • the inner ply 20 is at the same level as the flexible ply 7. For this, it is necessary to adjust either the position of the inner smooth 16 along the adjacent faces 10, or the position of the outer rails 17 relative to the light box 1 and therefore the position of the light box 1 with respect to the false ceiling 2. This adjustment is preferably made so that the internal smooth 16 are arranged opposite the outer rails 17, on the one hand and on the other. other faces adjacent 10.
  • the outer rails are arranged towards the edge of the tubular shape, offset relative to the internal smooth 16.
  • the light box can thus be integrated into the false ceiling so as not to be protruding but just tangent to the sheet forming the false ceiling.
