Definitions

• the present invention relates to improvements to false ceiling systems consisting of a canvas held in tension by peripheral beams, and especially to false ceilings using beams of this type called "invisible".
• the present invention aims to allow a user on the one hand to have accessories, for example of the lighting type, together with stretch ceilings and, on the other hand, to have easy and quick access to the technical volume arranged above the false ceiling, by simply dismantling a slab adjacent to it.
• the present invention thus relates to a false ceiling consisting on the one hand of at least one fabric stretched by its periphery on support elements integral with the ceiling and / or the walls of a room, characterized in that that it consists on the other hand of ceiling tiles held by these support elements using holding means allowing the disassembly of the tiles without requiring the total or partial disassembly of the fabric.
• the support elements will consist of heddles, namely peripheral healds and median healds which will be held relative to the ceiling, the latter being provided, on one of their sides , means for holding the fabric and, on their other side, means for holding the slabs.
• the tiles will be maintained by simple support, at least in part, on the median rails.
• These median rails will be provided, for their part on one side, with means for hooking the canvas and, on their other side, with a horizontal core intended to receive the slabs.
• the means for attaching the central rail will consist of two parallel vertical wings, namely a first wing disposed on the side of the fabric, and a second wing disposed on the side of the slabs, the internal wall of the second wing being provided with 'A shoulder capable of receiving, by simple support, the free end of a border secured to the fabric, so as to maintain it under tension.
• the shoulder will be disposed on the lower part of the second wing.
• Figure 1 is a perspective view and partial section of a composite ceiling according to the invention.
• Figure 2 is a cross-sectional view of a profiled element for implementing the ceiling according to the invention.
• Figure 3 is a cross-sectional view of an alternative embodiment of a profiled element for implementing the ceiling according to the invention.
• FIG. 4 is a top view of the embodiment shown in FIG. 3.
• Figure 5 is a cross-sectional view of another alternative embodiment of a profiled element for implementing the ceiling according to the invention.
• the false ceiling according to the invention essentially consists of two elements, namely a canvas 4 and rigid slabs 5.
• the maintenance of these elements is ensured by metal rails, namely peripheral rails fixed to the walls, not shown on the drawing, and middle rails 1 which ensure, on one of their sides, the maintenance of the fabric 4 and on their other side the maintenance of the slabs 5.
• central rail 1 which consists of an extruded metal profile, which essentially consists of a first vertical wing 9 and a second parallel wing 11 of the same length, which is kept apart from that -this by a transverse core 10.
• This transverse core 10 is extended beyond the first wing 9 by a support zone 13. Furthermore, the lower part of the wing 11 extends outward (that is to say in an opposite direction to the first wing 9), by a core 15 perpendicular to the wings 9 and 11 and which is intended to ensure the maintenance of the slabs 5.
• the core 15 extends inward, that is to say beyond from the internal face 11a of the second wing 11, in the direction of the first wing 9 over a short length, by a shoulder 17.
• the rail 1 is kept at a given distance from the ceiling (not shown in the drawing) of the room by tie rods 3, one end of which is secured to the latter, and the other end is fixed to the rail by means of brackets 19.
• a second stringer 2 of straight section is used. inverted T shape and the central branch of which is kept at a given distance from the ceiling by 3 'tie rods.
• the distance E existing between the central branch of the second T-shaped stringer 2 and the second wing 11 of the first stringer 1 is a function of the width of the slabs which it is desired to have in the vicinity of the stretched fabric 4.
• the stretched fabric 4 is provided, on its periphery, with a holding element, or border 25, which consists of an elastomer strip on which the fabric 4 is welded and the extreme free part of which rests by simply pressing on the shoulder 17, that is to say that it undergoes no embedding thereon and that its fixing is ensured by the very tension of the fabric, which is a known method of fixing, having in particular the following advantages:
• the upper part of the heddle 1 consists of a core 10 ′ arranged in the extension of the core 10, on the side of the fabric 4 and the two ends of which end in two small wings 28 parallel to the main wings 9 and 11 which close at their upper part by an edge 31, so as to constitute a slide 29.
• This slide 29 can receive a plate 30 in the form of a parallelogram whose width eu is less than the longitudinal opening of width e ⁇ separating the two edges 31, so as to be able to introduce it into the heddle 1, and the distance fi separating the other two sides of the parallelogram is equal to the internal spacing £ 2 of the two lateral wings 28.
• the present invention is particularly advantageous in that it makes it possible to constitute a mixed ceiling, that is to say a ceiling which is formed, over part of its surface, of a stretched canvas, adjoining one or more others parts reserved for technical elements, such as for example air vents, air conditioning, light bars, or simply tiles, for example, acoustically insulating.
