Definitions

  • the present invention relates to the field of false walls, and more particularly backlit false walls.
  • the invention relates more particularly to a frame profile for producing a backlit false wall, having a tubular-shaped profile body comprising a peripheral wall, a first longitudinal cavity having an opening on the peripheral wall and comprising means for attaching at least one canvas, a second longitudinal cavity having an opening on the peripheral wall and housing lighting means.
  • the frame profile is intended in particular but not exclusively for the creation of a backlit three-dimensional structure in stretched canvas(es).
  • wall soffits particularly false ceilings, comprise one or more frames, generally made of metal, on which one or two flexible canvases with a certain elasticity are hung tautly.
  • the canvases in question are provided with hanging means which can be hung on appropriate areas provided for this purpose on the profiles of the frame.
  • the invention aims to remedy this problem by proposing a frame profile for the creation of a backlit false wall, optimally limiting the peripheral shadow created by any profile when the latter is used in a backlit context.
  • the invention also aims to provide a frame profile making it possible to produce backlit three-dimensional structures of circular and/or curved shapes.
  • each cavity wall is inclined relative to the bottom wall at an angle of inclination of between 110 degrees and 130 degrees.
  • the flexible canvas is translucent or transparent.
  • a frame profile 1 intended to constitute, with similar frame profiles, a frame on which one or two stretched flexible canvas(es) can be fixed for the creation of a backlit false wall.
  • the frame profile 1 comprises a tubular profile body having a peripheral wall 2 defining a first and a second side faces 20, 21 connected to each other by an upper face 22 and a lower face 23.
  • the upper and lower faces 22, 23 are substantially flat while the side face 20 is rounded.
  • the radius of curvature of the side face 20 is identical to the width of the profile body itself identical to the height of the profile body.
  • the profile body comprises a first cavity 3 extending over the entire length of said body and having an opening on the first lateral face 20.
  • it is arranged to allow the attachment of two stretched canvases.
  • it comprises an internal wing 5 extending from the bottom of the first cavity 3 towards the opening of said cavity, so as to define within the first cavity 3 two symmetrical housings 30, 31 allowing the respective attachment of a canvas.
  • the attachment of the canvases on the frame profile 1 is carried out by means of shoulders 6, 7, 8 advantageously arranged on each face of the internal wing 5 as well as on the internal faces of the upper and lower walls of the profile body. These shoulders 6, 7, 8 are arranged to allow the attachment of attachment means, of the harpoon type, arranged at the edge of the canvas.
  • the profile body comprises a second cavity 4 extending over the entire length of said body and having an opening 40 on the second lateral face 21.
  • the first and second cavities 3, 4 thus open in an opposite direction to each other.
  • the second cavity 4 forms a cavity for receiving light means 9. It has a bottom wall 41 bordered by two divergent cavity walls 42, 43.
  • the two cavity walls 42, 43 delimit, with the upper and lower faces 22, 23, the opening 40.
  • the cavity walls 42, 43 thus define with the upper and lower faces 22, 23 two peripheral wings, of triangular section.
  • the second cavity 4 has a trapezoidal shape, advantageously isosceles.
  • the cavity walls 42, 43 inclined relative to the bottom wall 41 at an angle of inclination ⁇ of between 110 degrees and 130 degrees.
  • the bottom wall 41 is located at a distance from the opening less than or equal to half the distance separating the ends of the upper and lower faces 22, 23 which delimit the opening 40.
  • the second cavity 4 will be arranged to have a ratio between the height ( h 1 ) of the bottom wall 41 and the height ( h 2 ) of the opening 40 of the second cavity 4 of between 0.4 and 0.5 ( h 2 corresponding to the distance separating the ends of the upper and lower faces 22, 23).
