The present invention concerns a rail for a false partition and in particular a false ceiling, with tensioned fabric, and in particular for false ceilings in which the fabric is connected to the rail by means of laces.
False ceilings conventionally comprise one or more fastening rails that are fixed to each of the walls of a room, at a short distance therefrom, and an elastic fabric, for example made from polyvinyl chloride (PVC), which is deformed by tension so that its edges, provided with attachment means, can be fixed to the rails by these attachment means.
One of the main difficulties encountered in the technique of fitting such false ceilings is that this fabric, in order to offer a nice appearance, must be highly tensioned on the rails. However, false ceilings are generally disposed in rooms with relatively large surface areas, which makes it necessary to exert high tension forces on each of the sides of the fabric.
For this purpose, connecting the fabric to the rails by means of laces that are passed through orifices produced in the fabric and are connected to the rail by means of hooks disposed in piercings in the rail is known.
Such a false ceiling, as illustrated in FIG. 1, comprises a rail 1 connected to a polyvinyl chloride fabric 2, tensioned by means of elastic laces 3.
The rail 1 is in a U shape with a base wing 9 and two parallel wings 10, 11. The two wings 10, 11 are perpendicular to the base wing 9. The bottom wing 10 is provided with piercings 7. The rail 1 is fixed to a partition 12 of the room by means of screws, not shown, screwed into threaded holes 8 disposed on the base wing 9 of the rail 1.
The elastic laces 3 are connected on the one hand to the rail 1, by means of S-shaped hooks 4, and on the other hand to the fabric 2, by means of orifices 5 formed on a peripheral edge 6 of the fabric 2. The hooks 2 thus support the lace 3 at one of their ends and are disposed at their other end in the piercings 7 in the rail 1.
The drawbacks relating to the use of such a rail 1 can be seen. The presence of the hooks 4 close to the orifices 8 makes it difficult to fix the rail 1 to the partition 12. Fixing the hooks 4 in the orifices 7 is also lengthy and difficult. Moreover, it is necessary to pierce numerous orifices 7 in the rail 1, which also requires a great deal of time. In addition, if it is wished to use a given spacing of the orifices 7, according to the surface to be equipped, it is necessary either to have available a set of rails 1 with different spacings, or to pierce orifices 7 as required, which is fairly constraining.
A device for fitting a false ceiling is also known, described in patent application FR 2 861 769, consisting of a fabric tensioned by its periphery on rails secured to the walls of a room, comprising force-return hook pulleys that can be secured to the rails and can have a link pass through them, one end of which comprises means of fixing to the fabric and the other end of which provides the holding of a downstream force-return element, a second link forming a loop passing through the said downstream force-return elements and comprising means of coiling it, so as to reduce its length and thus bring the rails closer to the attachment points on the fabric. This device does not make it possible to immobilise the pulleys along the rails at chosen positions. The present invention proposes a rail for remedying these drawbacks.
The subject matter of the invention is thus a rail for a false partition and in particular a false ceiling, with tensioned fabric, of the type comprising one or more zones for fixing to a partition, and being intended to be connected to the fabric by means of one or more laces. The rail according to the invention comprises a runner accepting elements receiving laces, each lace reception element being, by means of a support, firstly mounted for sliding and secondly able to be immobilised with respect to said runner. The present invention solves the problems of positioning and immobilisation of the lace reception elements along the runner of the rail and therefore makes it possible to have points for tensioning the fabric at chosen intervals and to adapt their position as required in particular to the shape of the room and of the partition.
The rail can be fixed to any type of partition, such as a wall or ceiling.
In order to lock the lace reception element, the support advantageously has a threaded hole passing through it, in which the lace reception element is screwed.
It can be envisaged that only some lace reception elements are connected to such a support. Preferably, all the lace reception elements are connected to such a support.
In order to facilitate the fixing of the rail to the partition, the rail advantageously comprises a first wing intended to be fixed to a partition, and a second wing comprising the runner.
According to a variant, the first wing also comprises a runner. It is in this way possible to adapt the reception of the lace to the configuration of the room. It is thus possible to envisage that, by passing from a first rail to a second rail, the lace is first of all received on the first wing of the first rail and then on the second wing of the second rail.
According to another embodiment, the first and second wings are joined in a single wing. This wing therefore comprises the runner while providing the fixing of the rail to the partition.
Preferably, the two wings are made in one piece.
The lace reception element may be any element comprising an orifice, thus allowing passage of the lace and securing thereof to the rail. It is in particular possible to use any curved piece of the hook type, or an eye. The use of a hook makes it possible to receive the lace easily.
Another subject matter of the invention is a false partition and in particular a false ceiling of the type comprising a tensioned fabric connected to a rail described above by means of one or more laces.
The laces can be chosen from all types of lace, and preferably from elastic laces. It is possible in particular to use elastic laces of the Sandow® type.
To receive the laces, the fabric is advantageously provided with orifices intended to receive the laces.
Other aims, characteristics and advantages of the invention will emerge from a reading of the following description, given solely by way of example, and made with reference to the accompanying drawings, in which:
FIG. 1, already described, illustrates part of a false ceiling comprising a fabric tensioned by means of a lace fixed to a rail according to the prior art,
FIG. 2 illustrates a rail according to the invention,
FIG. 3 illustrates a rail according to a variant of the invention,
FIG. 4 illustrates part of a false ceiling comprising a fabric tensioned by means of a lace fixed to a rail according to a first embodiment of the invention, and
FIG. 5 illustrates part of a false ceiling comprising a fabric tensioned by means of a lace fixed to a rail according to a second embodiment of the invention.
The rail 27 according to the invention, as illustrated in FIG. 2, comprises a first ring 13 intended to be fixed to a partition by means of fixing zones, that is to say threaded holes 15. The rail 27 also comprises a second wing 14, perpendicular to the first wing 13. The second wing 14 comprises a runner 16 able to slidably accept a support 18 through which a threaded hole 19 passes. The first wing 13 and second wing 14 are made in one piece. The eyes 17 are slidably mounted by partial screwing in the support 18 by means of a threaded zone 21 able to be screwed into the threaded hole 19 in the support 18. The eyes 17 are provided with an orifice 200 intended to accept laces.
The runner 16 is in the shape of a U provided with a bottom wing 20, and two parallel lateral wings 21, 22 perpendicular to the bottom wing 20. The runner 16 is also provided with two rims 23, 24 disposed at the top of the lateral wings 21, 22, and which are parallel to the bottom wing 20. The form of the runner 16 thus delimits a recess 25 able to slidably guide the support 18 and consequently the eye 17 partially screwed in the support 18.
The support 18 can be of square or rectangular cross section, its width and height being chosen so that the support 18 can slide in the recess 25.
Each eye 17 is locked simply by complete screwing of the eye 17 in the support 18. The locking is then effected when the threaded zone 21 of the eye 17 comes into contact with the bottom wing 20 of the runner 16. It is thus possible to position each eye 17 quickly and simply at the required place on the rail 27 by sliding the eye 17 in the runner 16, and then by locking, completely screwing the eye 17 in the support 18.
According to the variant illustrated in FIG. 3, where the elements identical to those in FIG. 2 bear the same reference signs, the first wing 13 of the rail 27 also comprises a runner 30. The runner 30 is identical to the runner 16 of the second wing 14 and is disposed above three threads 15. The runner 30 is in the shape of U provided with a bottom wing 31, two parallel lateral wings 32, 33, perpendicular to the bottom wing 31. The runner 30 is also provided with two rims 34, 35 disposed at the top of the lateral wings 32, 33, and which are parallel to the bottom wing 31. The shape of the runner 30 thus delimits a recess 36 able to slidably guide a lace reception element identical to the one described in FIG. 2.
According to this variant of the invention, the rail 27 is thus provided with two runners 16, 30. This arrangement makes it possible to obtain original or more appropriate configurations, allowing lace reception on one or other of the two runners 16, 30.
The false ceiling illustrated in FIG. 4, on which the elements identical to those in FIG. 2 bear the same reference signs, comprises a tensioned fabric 2 made from polyvinyl chloride provided with orifices 5 formed on a peripheral edge 6 of the fabric 2. The fabric 2 is connected to the previously described rail 27 by means of elastic laces 3. The rail 27 is fixed to a wall 12 by virtue of screws 26. The elastic laces 3 tension the fabric by passing alternately through an orifice 5 in the fabric 2 and then through the orifice 200 of an eye 17 locked in the runner 16 of the rail 27.
In the embodiment illustrated in FIG. 4, the first wing and the second wing are joined in a single wing 28. As shown, the wing 28 is merged with the bottom wing 20 of the runner 16 illustrated in FIG. 2. The wing 28 can however also be identical to the wing 14, also illustrated in FIG. 2. The rail 27 is fixed to the wall 12 by means of the screws 26 disposed in fixing zones of the wing 28, which are threaded holes, not shown.
The rail 27 according to the invention thus makes it possible to arrange the eyes 17 in an optimal fashion, according to the spacing of the orifices 5 in the fabric 2. They also make it possible to avoid the numerous piercings provided in the rail 1 of the prior art.
