Description
The present invention relates to the field of false partitions such as false ceilings and false walls and in particular those consisting of a tensioned flexible fabric attached along its borders to a support fixed to the walls or to the ceiling of a room of a building.
The known false partitions are based on the principie of a tensioning of the flexible fabric on the frame consisting of abutted rails, in a perfectly fíat manner, horizontally or vertically depending on whether it concerns a false ceiling or a false wall.
These false ceilings or false walls, once mounted on their rails necessarily show an often important and therefore visible clearance between the periphery of the tensioned partition and the walls supporting the fixing rails. Such functional clearance necessarily results from the need to provide for a sufficient intermedíate space between the wall and the tensioned surface for inserting the harpoon-shaped peripheral hooks of the fabric inside the rails so that the end rim of the harpoon comes to rest on a shoulder provided for this purpose on the external flange of the rail closest to the wall in accordance with what is shown in Figure 1 for example.
However, in many cases, such residual space between the fabric and the wall can be visually distracting because it is a hollow joint giving a sometimes very unsightly impression. Besides, it may be the source of inconvenient passages of air causing soiling or likely to disrupt some ventilation installations.
To overeóme these drawbacks, a system for fixing tensioned false partitions according to Figure 1 is already known, specifically from the international patent application PCT/FR2009/000021 in the ñame of NORMALU, with said false partitions consisting of a flexible fabric attached by its borders to a frame fixed to the wall or to the ceiling of a room, with said frame consisting of a rail having a reduced size consisting of abutted profiles comprising at least two advantageously parallel flanges, with one of which, referred to as external, comprises, on one side, means for fixing the fabric to the wall or to the ceiling and has, on the other side, a shoulder extending perpendicularly towards the inside of the rail in the direction of the room and the other one, referred to as internal, is connected to the first one by a web located at one end thereof and the other end of which extends slightly beyond the shoulder of the first flange to form the peripheral abutment of the fabric that is tensioned substantially perpendicularly to the internal flange by its borders provided with a harpoon inserted like a "gooseneck" between the two flanges of the rail and consisting of a first section connected to the fabric and a second section folded over the first one, the end rim of which rests on the shoulder of the external flange. The system is such that said end rim of the harpoon comprises a detachment lip perpendicularly originating from the resting zone of said rim on the shoulder and extending under said shoulder into the gap lying between the latter and the internal flange of the rail, such that said lip acts as a lever for a dismantling tool, which makes it possible to push the end rim of the harpoon out of the shoulder, without the tool penetrating into the rail, to easily disassemble the fabric from the frame.
Said International application also discloses a particularly advantageous embodiment shown in Figure 2, wherein the shoulder provided on the external flange to act as a support for the end rim of the harpoon is replaced by a notch formed in the thickness of the external flange of the rail to act as a resting zone for said end rim of the harpoon. The notch preferably has the general shape of a right-angled triangle wherein the smaller side of the right angle, perpendicular to the plañe of the external flange of the rail, in a configuration referred to as "minirail", is used to support the end rim of the harpoon and the hypotenuse facilitates the engagement of the rim of the harpoon when mounting the fabric.
However, considering the shape of the shoulder, when for example a dismantling tool is used to pulí the harpoon out of the mini-rail by leaning on the detachment lip, only the most extreme and thus the most flexible part of said lip can be used as a support. The result is that very often the lip deforms without causing said lip to be sufficient pushed back against the flange connecting the harpoon to the fabric to unfasten the radial face of the lip of the harpoon resting on the shoulder of the mini-rail. This results in that extracting the harpoon downwards and thus unfastening the fabric is not possible. A system for fixing tensioned false walls is also known from the preamble of claim 1 in the patent application FR2926100K. A tensioned false ceiling comprising a resilient sheet provided with an anchoring flange Hable to be inserted into a groove attached to the wall using fixing rims is also known from the patent application EP0043466.
The present invention aims at overcoming the drawbacks of the prior art by providing a system for fixing a tensioned false partition, for instance a ceiling between two walls, making it possible to obtain, after positioning such ceiling, a very small residual clearance between the fabric and the wall and thus to ensure easy mounting and dismounting.
According to the invention a system for fixing tensioned false walls is provided according to claim 1.
It should be understood that, when using a rail type according to the invention, a part of the detachment lip located closer to the end rim of the harpoon can be used as a lever and rendered less flexible and thus said lip can be more efficiently pushed back. In addition, this type of rail makes it possible, on the one hand, to increase the space between the wall and the lip so as to make the passage of the dismantling tool easier and, on the other hand, to facilítate the positioning of the harpoon inside the rail.
Other characteristics and advantages will become apparent from the following description of an alternative embodiment of the fixing system of the invention while referring to the appended figures wherein: - Figure 1 is a partial vertical sectional view of a false ceiling consisting of a tensioned fabric, and comprising a first alternative rail attached to the upper part of a wall of a room according to the prior art; - Figure 2 is a partial vertical sectional view of a false ceiling consisting of a tensioned fabric, and having a second alternative rail attached to the upper part of a wall of a room according to the prior art;
Figure 3 is a vertical sectional view of a fixing system according to the invention. - Figure 4 is a vertical sectional view of the rail of a fixing system according to the invention.
Figure 1 shows the end part of a false ceiling according to the prior art, which consists of a flexible fabric 1 tensioned horizontally under the ceiling 2 of a room. This fabric 1 is fixed along its borders to a support consisting of a horizontal rail 3, itself fixed to the upper part of a wall 4 of the room by suitable means, not shown, such as screws. Such rail 3 comprises an external vertical flange 5 which extends parallel to the wall 4 and in cióse proximity thereof. An upper horizontal web 6 extending over a small distance, for example of the order of a few millimeters originates from such external vertical flange 5, at about mid-height, towards the inside of the room. This web 6 is extended at its end by an internal vertical flange 7 which extends downwards, a little lower than the external flange 5 cióse to the wall 4, i.e. the internal vertical flange 7 is a bit higher than the external flange 5 of said rail. Said external flange 5 has, at its lower end, a shoulder 8 extending horizontally towards the inside of the room, over a short distance which is smaller than the width of the web 6. Said right-angled shoulder 8 advantageously has a rounded end.
The lower part of the external vertical flange 5, the upper horizontal fabric 6 and the internal vertical flange 7 define a downwards opening recess 9 wherein the fixing harpoon 10 welded to the periphery of the tensioned flexible fabric 1 can be engaged.
In cross-section the harpoon 10 has the shape of a hook extending toward the wall 4 and opening downwards. It comprises an internal branch 10a, through which it is connected to the fabric 1, and an external branch 10b having the shape of a rim with a rounded end, which is bent downwards. When the fabric 1 is tensioned, the harpoon 10 bears on the shoulder 8 through the lower end of its external branch 10b which extends downwards. Considering the small size of the rail 3 and in order to facilítate the dismantling of the fabric 1, the harpoon 10 has, at the end of the external branch 10hp_ a detachment lip 11, perpendicularly originating from the región of the end flange bearing on the shoulder 8; this lip 11 is such that it may extend under said shoulder 8 into the gap between said shoulder 8 and the internal vertical flange 7 of the rail 3, so that the lip 11 can act as a lever for a dismantling tool, for example a conventional spatula, making it possible to push the end rim of the harpoon 10 out of the shoulder 8 without it being necessary to push said spatula into the rail 3 to easily dismantle the fabric 1 from its frame.
On the contrary, as for the mounting of the fabric 1 into a rail 3, a spatula is traditionally used, as already used in the prior art, by pushing the harpoon 10 back into the space 9 of the rail 3 so that it snaps onto the end rim of the harpoon 10 on the shoulder 8 of the flange 5 of the rail 3.
According to a particularly advantageous alternative embodiment shown in Figure 2, the shoulder 8 provided on the external vertical flange 5 of the previous alternative embodiment to act as a support for the end rim of the harpoon 10 is replaced by a notch 12 formed in the thickness of the external flange 5 of the rail 3 to act as a bearing zone for said end rim of the harpoon 10. Advantageously, the notch 12 has the general shape of a right-angled triangle wherein the smaller side 12a of the right angle, perpendicular to the plañe of the external flange 5 of the rail 3 acts as a support for the end rim of the harpoon 10 and the hypotenuse 12b facilitates the engagement of the rim of the harpoon 10 when mounting the fabric 1.
However, considering the shape of the shoulder 8, dismantling the harpoon 10, by pushing the end rim of the harpoon 10 out of the shoulder 8 of the rail 3 is difficult because the dismantling tool acts as a lever on the end portion of the lip 11. As a matter of fact, such part which is the most flexible one of the lip is deformed without making it possible to sufficiently push back the end rim of the harpoon 10 and thus the disengagement of the harpoon 10 from the rail 3.
According to the invention, the Figures 3 and 4 show a System for fixing tensioned false partitions, consisting of a flexible fabric 1 attached by its borders to a frame attached to the wall or to the ceiling of a room. Said frame consists of a rail similar to the one previously described. Said rail thus comprises an external vertical flange 5 and a horizontal web 6 originating, at approximately mid- height of said external vertical flange 5 and extending over a short distance towards the inside of the room. Such web 6 is extended at its end by an internal vertical flange 7 extending downwards a little lower than the external vertical flange 5. The external vertical flange 5 has, at its lower end, a shoulder 8. The lower part of the external vertical flange 5, the upper horizontal web 6 and the internal vertical flange 7 define a downwards opening recess 9.
The tensioned flexible fabric 1 comprises a fixing harpoon 10 welded to the periphery of said fabric 1; said harpoon 10 may be engaged into the recess 9 to hold the fabric 1 tensioned over the frame. The harpoon 10 is identical to the one described above and has, in cross-section, the shape of a hook extending towards the wall 4 and opening downwards. It comprises an internal branch 10a through which it is connected to the fabric 1, an external branch 10b having the shape of a rim with a rounded end, which is bent downwards and a detachment lip 11 originating from the end of the external branch 10b and extending perpendicularly to the región of the end rim bearing against the shoulder 8.
However, to enable an effective dismantling of the fabric 1, the rail 3, according to the invention comprises a cant 13 on the face of the shoulder 8 located at the end of the external vertical flange 7 procuring a bevel entry to facilítate the insertion of a dismantling tool. Said cant 13 is an inclined fíat face extending from the lower end of the external vertical flange 5 in the direction of the recess 9 so that said face forms an acute angle with the external vertical flange 5.
Advantageously, this angle is smaller than or equal to 45°.
Thus, with the rail 3 thus configured, it will be understood that the dismantling tool can bear on a portion of the detachment lip 9 closer to the end rim of the external branch 10b, with said portion being thus stiffer and therefore less flexible, and enabling an efficient pushing back of the external branch 10b and the disengagement of the harpoon 10 of the rail 3.
Besides, the cant 13 facilitates the insertion of the harpoon 10 into the recess 9 because the latter bears on the cant 13 and gradually closes until it can be inserted into the gap between the shoulder 8 and the internal vertical flange 7. Then, once inside the recess 9, the harpoon 10 opens and the end rim of its external branch 10b comes to rest on the shoulder 8.
It goes without saying that the fíat shape of the cant 13 at the end of the external vertical flange 5 of the rail 3 is given only as a non restrictive example of the invention and that any other shape, a skew surface of the cant 13 for instance could be considered without departing from the scope of the invention.
It should also be understood that the shoulder 8 may be offset relative to the free end of the external vertical flange 7 and thus, the cant 13 may no longer be in contact with said shoulder 8 without departing from the scope of the invention.
Similarly, the shoulder 8 provided on the external vertical flange 5 to act as a support for the end rim of the harpoon 10 may be replaced by a notch 12 according to the one shown in Figure 2, in the thickness of the external flange 5 of the rail 3 to act as a support area for said rim end of the harpoon 10 without departing from the scope of the invention.
Eventually, it goes without saying that the present invention is not limited to the alternative embodiments described, but may be modified or adapted according to special needs or requirements, without departing from the scope of the invention.
