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 in the peripheral wall and housing light means.
• the frame profile is intended in particular but not exclusively for the production of a three-dimensional backlit structure in stretched canvas (s).
• the krafte-walls in particular the false ceilings, comprise one or more frame (s), generally metallic, on which are hung (s) stretched (s) one or two flexible canvas (s) having a some elasticity.
• the fabrics in question are provided with hooking means that can hook onto appropriate areas provided for this purpose on the frame profiles.
• the frame profile of the aforementioned application like all the frame profiles of the prior art, creates peripheral shadow zones.
• the invention aims to remedy this problem by providing a frame profile for the production of a backlit false wall, optimally limiting the peripheral shadow created by any profile when the latter is used in a backlit context.
• Another object of the invention is to provide a frame profile making it possible to produce backlit three-dimensional structures of circular and / or curved shapes.
• the invention provides a frame profile for producing a backlit false wall, having a profile body of tubular shape comprising a peripheral wall, a first and a second cavity longitudinal sections respectively having an opening on the peripheral wall, said first cavity comprising means for attaching at least one canvas, said second cavity accommodating luminous means, the frame profile is remarkable in that said second cavity comprises a wall of bottom bordered by two divergent cavity walls delimiting the opening of the second cavity.
• each cavity wall is inclined relative to the bottom wall at an angle of inclination of between 110 degrees and 130 degrees.
• the ratio between the height of the bottom wall and the height of the opening of the second cavity is between 0.4 and 0.5.
• the ratio between the depth of the bottom wall and the height of the opening of the second cavity is between 0.3 and 0.4.
• said second cavity has a trapezoidal shape.
• the first and second cavities open onto the peripheral wall in a direction opposite to each other.
• the peripheral wall defines with the cavity walls a junction edge.
• the peripheral wall has two side faces, a flat upper face and a flat lower face, the opening of the second cavity (4) opening onto one of the side faces and being delimited by said upper and lower faces.
• This arrangement has the advantage of eliminating the residual shadow zones created by the profile when it is used in a backlit context.
• the other side face onto which the opening of the first cavity opens has a rounded shape.
• the invention also relates to a backlit false wall comprising a frame comprising an arrangement of butted frame profiles and at least one flexible canvas attached to the frame by means of hooking means provided at the edge of said canvas, characterized in that that each frame section is as described above and in that at least one frame section comprises light means housed in the second longitudinal cavity.
• the light means are mounted on the bottom wall of the second cavity.
• the flexible fabric is translucent or transparent.
• Figure 1 shows a frame profile according to the invention for producing a backlit false wall.
• a frame profile 1 intended to constitute, with similar frame profiles, a frame on which it can be fixed one or two flexible canvas (s) stretched (s ) for the realization of a backlit false wall.
• the frame profile 1 will be described with respect to its position illustrated in the figure.
• 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 planar 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 side face 20.
• the illustrated embodiment is arranged to allow the hanging 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 hanging of a canvas.
• the canvases are attached to the frame profile 1 by means of shoulders 6, 7, 8 advantageously formed on each face of the inner flange 5 as well as on the inner faces of the upper and lower walls of the profile body. .
• These shoulders 6, 7, 8 are arranged to allow the attachment of hooking means, of the harpoon type, provided at the edge of the canvas.
• the profile body has a second cavity 4 extending over the entire length of said body and having an opening 40 on the second side 21 side.
• the first and second cavities 3, 4 thus open in a direction opposite to each other.
• the second cavity 4 forms a receiving cavity for light means 9. It has a bottom wall 41 bordered by two divergent cavity walls 42, 43.
• the two cavity walls 42, 43 define, with the upper faces and lower 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 a 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 between the ends of the upper and lower faces 22, 23 which defines the opening 40.
• the second cavity 4 will be arranged to have a ratio between the height (h,) of the bottom wall 41 and the height (h 2 ) of the opening 40 of the second cavity 4 between 0.4 and 0, 5 (h 2 corresponding to the distance separating the ends of the upper and lower faces 22, 23).
• the second cavity 4 so that the latter has a ratio between the depth (p) of the bottom wall 41 and the height (h 2) of the opening of the second cavity of between 0 , 3 and 0.4.
