Description

The invention relates to a removable wall designed to be easily mounted and dismounted on any surface of interest, in particular a wall, a ceiling, a wall, a ceiling, a wall, a ceiling, a wall, a ceiling, a wall, a wall, a ceiling, a wall ground etc. More specifically, the invention relates to attachment means for easily clipping and unclip such a removable wall. The invention also relates to a method of covering a surface, such as a wall, a ceiling or a floor, by a removable wall. The method according to the invention makes it possible to cover an anterior coating, for example damaged, without having to disassemble said anterior coating, or to cover an opening, etc.

False ceilings with slabs are known, the slabs of which are supported by T-shaped support elements on which they rest. The slabs are assembled from above with respect to the T-shaped support elements. Also, when one or more false ceiling slabs are damaged, it is difficult to replace them without intervening on a very large surface of the false ceiling. Most often, it is necessary to remove a very large number of slabs in relation to the number of slabs that are actually to be replaced. To remedy this drawback, it is known to leave the false ceiling slabs as is and cover the entire surface of the false slab ceiling with a fabric such as a suspended false ceiling. It is also known, when it is desired to insert light elements in a recess made in a ceiling, to cover said niche with a translucent material web extending in the extension of the wall from which the recess is formed. The fabric allows the light emitted by the light elements of the niche to pass through, while giving the impression of a continuous surface between the ceiling and the fabric covering the niche. In all cases, the fabric is mounted on a frame for stiffening, said frame being secured by any means T-elements 35 supporting the slabs.

However, the attachment means frames have dimensions such that when two frames are arranged next to each other, they provide a space between the two adjacent stretched canvas carried by each of the frames. In the case of an illuminating ceiling, this creates a gray area at the level of the connection between the two frames. Moreover, in all cases, tightness of the suspended false ceiling covering the false ceiling slabs is not ensured so that dust, gnats or air can pass between the suspended false ceiling and the false slab ceiling. At present, in the case of illuminating ceilings, in order to prevent midges or dust from getting stuck in the niche provided with the luminous elements, it is known to arrange two canvases one above the other and carried by the same frame so that the midges are not visible through the translucent material web. Such a solution is expensive and difficult to implement.

In the invention, it is sought to provide a means for covering a pre-existing false ceiling, or any other surface of interest, including a wall, a floor, or a recess made in any wall, by a removable wall not presenting all or part of the disadvantages of the state of the art.

For this, in the invention, there is provided a removable partition comprising a frame between the amounts of which extends a fabric or other flat element intended to cover the desired surface. The connection between the planar element and the frame is such that said planar element extends beyond the frame which holds it so that neither the frame nor the surface to be covered are no longer visible once the removable partition has been placed. Thus, in the case where there are two removable partitions according to the invention side by side to cover two adjacent surfaces, there is virtually no space between the two planar elements of the two adjacent removable partitions. Advantageously, the removable partition according to the invention is provided with fastening means for clipping and unclipping at will said partition of the surface to be covered. In particular, the fixing means comprise elastic hooks symmetrically fixed to fastening elements, said fastening elements being arranged on a perimeter of the surface to be covered. The frame of the removable partition is then clipped on these elastic hooks that hold it in position. The removable partition according to the invention allows a rapid recovery of any desired surface. In the case of a ceiling to be renovated, the installation of removable partitions according to the invention can be done above or below, so that it is not necessary to undertake a tedious disassembly of the existing ceiling , and in the case of a wall, the installation of the movable partitions faces the wall. In all cases, the covered surface is no longer visible when facing the removable partition that has just been placed. The removable partition can easily be disengaged from the fastening means so as to be replaced at will or to give access to the surface it covers.

The invention therefore relates to a removable wall provided with a frame and a panel extending between four sides of the frame, the removable wall being intended to be mounted and / or disassembled on a surface of interest, characterized in that it is provided with a hooking system adapted to maintain the frame on the surface of interest, the attachment system comprising at least two clips arranged on either side of the frame, each clip comprising a housing upper for cooperating with the surface of interest and a lower housing for cooperating with the frame, and in that at least two opposite sides of the frame are provided with a long oblique wing extending obliquely outwardly from the frame to the panel, so that the panel covers said frame and said staples. Panel means any flat surface intended to extend parallel to the surface of interest that the removable wall must cover. The surface of interest is indifferently a wall, a ceiling, a hole made in a wall or a ceiling, a recess, a floor etc.

Advantageously, the long oblique wing extends on the four sides of the frame, so as to hide the pre-existing surface on the entire contour of said frame. Of course, it can also extend only on two or three sides, or even on portions of sides only, depending on the surface to be covered, its accessibility etc.

The long oblique wing is inclined outwardly of the removable wall so that the panel edge located at a low end of said oblique long wing completely covers the frame which supports said panel and depending on the case. external contour of the surface of interest on which the removable wall is mounted. The lower end of the long oblique wing is the free end, that is to say not integral with the frame. Thus, only the panel is visible from the outside, hiding not only the surface of interest to be covered, but also the frame and any attachment means used to fix the removable wall on the surface of interest.

By staple means any point and elastic fastening system capable of being on the one hand, fixed to the surface of interest and, on the other hand, fixed to the removable wall so as to maintain said removable wall fixed on the surface interest. The staples are preferably arranged symmetrically following a contour, or external perimeter, of the surface to be covered, so as to ensure good retention of the removable wall on said surface. The staples may for example be mounted interlocking on the T-support structure of a false slab ceiling or on brackets specially mounted on a contour of the surface to be covered. The arrangement of the staples is such that they are also covered by the panel of the removable wall that the staples support. Advantageously, the removable wall is engaged elastically in the clips. Advantageously, at least one clip comprises a lower housing pivotally mounted on the upper housing of said clip. For example the lower housing is mounted on an axis intended to extend perpendicularly to the flat surface of the removable wall that the clip must support. Thus, the lower housing can be pivoted so that said lower housing opens on the same side as the upper housing, or on the opposite side etc., depending on the position of the structural element on which the upper housing must be nested. It is also possible to provide a clearance of the lower housing around an axis intended to extend parallel to the flat surface of the removable wall. The pivoting of the lower housing relative to the upper housing allows to adapt to existing structures, by hooking the upper housing to said existing structure, and pivoting the lower housing accordingly to allow clipping of the removable wall. Preferably, the clip comprises clamping means for blocking the rotation of the lower housing relative to the upper housing once said lower housing is in the desired position.

In a particular embodiment of the clip according to the invention, it is possible to use different materials to make the upper housing and the lower housing, so that the upper housing is made of rigid material and the lower housing made of flexible material. Thus, the elastic clipping of the frame in the lower housing is possible, without there being any risk of detachment of the staple of the surface of interest, since it is rigidly mounted on said surface through the upper housing . According to embodiments of the removable wall according to the invention, it is possible to provide all or part of the following additional features: -The removable wall is provided with a seal extending on a perimeter of the frame so to be crushed between the frame and the edges of the surface of interest.

The presence of such a seal that extends over a whole perimeter of the frame makes it possible to seal the volume formed between the surface of interest and the removable wall covering it. The seal is thus crushed between the frame and the surface of interest. Furthermore, the seal avoids metal squeaks in the case where the frame is mounted on a structural element also metallic. Of course, in this case, it is possible to provide a seal on a partial perimeter of the frame. The edges of the surface of interest include both the edges of said surface as such that fastening means following a contour of said edges or possibly fixed on said edges, depending on the surface to be covered. - The wall comprises a slab whose outer edges, forming the frame of the wall, are hollowed so as to provide a fastening means for cooperating with the surface of interest so as to maintain said frame on said surface of interest , and a long oblique wing.

The frame and the panel are formed in the same block, which can be in any material including Placo, wood, etc. By external rim, we mean the four sides of the slab. The sides of the slab are carved so as to provide, for example, tabs projecting from said sides, parallel to the flat surface of the slab intended to form the panel, said tabs forming the means of attachment of the slab on the surface to be covered. The horizontal tabs can snap into the clips located at the level of the surface of interest to be covered, or directly into a support element of the surface to be covered. - The wall comprises a profile forming the frame of said wall, said section supporting a false wall tensioned forming the panel of said wall. The false stretched wall, such as a suspended false ceiling, may be canvas, metal or other. Thus, in the case of a coating to withstand the fire, a taut metal wall, whose frame is also provided with a seal to stop the air, allows to meet the required standards. In this embodiment, it is possible to provide a profile capable of being clipped onto the staples, by elastic engagement of horizontal legs, that is to say parallel to the panel, said profile in the lower housing of the staples. The horizontal legs are located above the oblique wings, and are thus covered by the oblique wings. The invention also relates to a method of covering a surface of interest by a removable wall according to the invention, said method comprising the following steps: - staples are fixed on the edges of the surface of interest to be covered

the removable wall faces the surface of interest to be covered and the removable wall is supported on the staples so as to clip it into said staples. According to examples of implementation of the method according to the invention, it is possible to provide all or part of the following additional steps: - the dimensions of the surface of interest to be covered are measured; a frame of measured dimensions is prepared and a panel is hung on the sides of the frame so as to obtain a removable wall of the desired dimensions. - Fastening elements are arranged on the edges of the surface of interest to be covered and the staples are fixed on the attachment elements. The attachment elements are in particular brackets attached to the edges of the surface of interest, but it can also be pre-existing supports that maintain for example the surface of interest that it is desired to cover. The invention will be better understood on reading the description which follows and on examining the figures which accompany it. These are presented as an indication and in no way limitative of the invention. The figures represent: FIG. 1: a partial schematic cross-sectional representation of a false ceiling with slabs covered by a removable wall according to a first exemplary embodiment of the invention; - Figure 2: a partial schematic representation in cross section of a recess formed in a ceiling and covered by a removable wall according to a second embodiment of the invention; - Figure 3: a schematic representation of a clip according to the invention; - Figure 4: a partial schematic representation in cross section of a false slab ceiling covered by a removable wall according to the second embodiment of the invention; - Figure 5: a schematic representation seen from above of a false ceiling slabs covered with removable walls according to the invention; - Figure 6: a schematic front view of a recess in a wall, and intended to be covered by a removable wall according to the second embodiment of the invention. In FIG. 1, a false ceiling with slabs can be seen at two adjacent slabs 1 and 2 supported at least partially by a same T-shaped support member 3. More specifically, a rim 4, 5 of each of the slabs 1, 2 adjacent rests on the same support element 3 T. The slabs 1, 2 of the false slab ceiling is covered by removable walls 10 according to a first embodiment of the invention. The removable wall 10 is formed by a slab, for example plaster, whose outer edges 11 have been previously dug, so as to fit on each of said flanges 11 a horizontal lug 12 a long oblique wing 13. The horizontal lug 12 s' extends parallel to the false ceiling 1, 2 that the removable wall 10 covers and the long oblique wing 13 extends obliquely outwardly relative to the slab 10, from the horizontal tab 12 to a flat surface 14 formed by an outer face 14 of the slab 10.

By external face is meant the face intended to be seen by the users, as opposed to the internal face directed surface to be covered. The horizontal lug 12, which extends over the entire length of the rim 11 in question, clippes punctually in local fasteners, such as staples 20. In all cases, the long oblique wing 13 extends towards the lug. in such a way that the outer plane faces 14 of the two adjacent slabs 10 are almost glued to each other at the level. A distance d between two flanges 11 facing each other of two adjacent slabs 10 is almost zero with respect to a distance D that existed until now with the prior art covering solutions, in which the walls intended to cover the surface of interest were most often brought back on said surface of interest by a fastening system whose size did not allow an attachment of the two flanges 11. The distance d between two slabs according to the invention is of the order millimeter, while the distance D of the state of the art was rather ten millimeters. FIG. 3 shows in more detail a staple 20 used in the various examples described for holding the removable wall 10, 30 according to the invention in position relative to the surface of interest 1, 2, 40, 50 to be covered. . Each clip 20 comprises an upper housing 21 in which is intended to be fitted a fastening element, such as a flange of the T-shaped support element, or a bracket or the like. The housing 21 is intended to fit an outer contour of the fastening element on which the clip 20 is to be mounted. The clip 20 also comprises a lower housing 22 in which is intended to be clipped the frame of the removable wall. The lower housing 22 is formed for example by two tongues 23 and 24. The main tongue 23 extends radially from the upper housing 21, outwardly relative to the wall to be covered, and the secondary tongue 24 extends in protruding inwardly relative to the main tongue 23, the lower housing 22 being formed between the two tongues 23, 24. Advantageously, the clip 20 is made of elastic material, so that the removable wall can be clipped elastically in the lower housing 22.

In the case of the example shown in Figure 1, the lower housing 22 receives the horizontal tab 12 of the slab 10, the oblique long wing 13 extending along the secondary tongue 24 and beyond said tab secondary 24, so that the flat surface 14 of the slab 10 completely covers said staple 20. In Figure 2 is shown a second example of a removable wall 30 according to the invention. The removable wall 30 comprises a frame 31 formed by a profile, and a panel 32 formed by a false suspended ceiling, for example canvas, whose edges 33 are held in position in a housing 34 of the profile 31. More specifically, a wing long oblique 35 and an oblique short wing 36 of the section 31 extend obliquely outwardly relative to the center panel 32, and form between them the housing 34. The frame 31 has four sides 37, each provided with a wing long oblique 35 and an oblique short wing 36, the four sides 37 of the frame 31 defining the dimensions of the removable wall 30. Each side 37 also comprises a horizontal lug 38 intended to be clipped into a lower housing 22 of a staple 20. The horizontal tab 38 extends parallel to the flat surface 32 of the wall 30.

More specifically, in the example shown in Figure 2, the removable wall 30 is clipped to cover a recess 40 formed in a ceiling 41, said recess 40 having illuminating elements 42. In order to cover the recess 40 with the removable wall 30, brackets 43 are fixed on vertical walls 44, or edges 44, of the recess 40.

The brackets 43 comprise an arm 45 extending radially from the vertical wall 44 towards the center of the recess 40. The upper housing 21 of a staple 20 is embedded on each arm 45, so that the lower housing 22 of each of said staples 20 is directed towards the volume of the recess 40. Depending on the dimensions of the removable wall 30 and the recess 40 to be covered, there are more or fewer brackets 43 on the vertical walls 44, each bracket 43 receiving As can be seen in FIG. 6, which schematizes the use of a removable wall 30 according to the invention for covering a recess 51 made on a wall 50, said wall 30 is brought towards the recess 51 , directing the profile 31 to the interior of the recess 51. The removable wall 30 used here is the same as that used to cover the lighting niche of the ceiling (Figure 2). The horizontal tabs 38 of the profile 31 are clipped onto brackets 53 secured to the side walls 52, 54 bordering the recess 51.

Thus, whether it is to cover a recess 40 formed in a ceiling or a recess 51 made in a wall, the removable wall 30 according to the invention is easily clipped and unclipped onto the brackets 43, 53 that can either directly receive the profile 31, by clipping the horizontal tabs 38 on the projecting arm 45, or receive the clip 20 which itself will allow the clipping of the horizontal tab 38 in the lower housing 22. In the examples shown in Figures 2, 4 and 6, a seal 39 is fixed on the profile 31 of the removable wall 30. More specifically, each side 37 of the frame / profile 31 has a seal 39 extending over an entire length of the upper surface of the horizontal leg 38. Length means the largest dimension of the side 37 considered. The seal 39 is crushed against the clip 20 or the bracket 45, 53 on which the wall 30 is clipped. The seal 39 running along the entire length of the side 37 of the profile 31, it is crushed over its entire length against the edge of the surface of interest that it runs, which ensures the tightness of the volume formed between the removable wall and the surface it covers. Thus, no dust or gnat can pass from the edges of the flat surface 32 towards the covered surface of interest. In the case of a niche having luminous elements 42, it avoids having to have two successive flat surfaces to not see the presence of crushed midges on the flat surface on the luminaire side. In the example shown in Figure 2, if it is desired to seal the volume of the niche 40, it is necessary to use brackets 43 extending along the vertical walls 44. Indeed, the seal 39 is crushed against said bracket 43, which if it is interrupted creates an absence of support against which the seal 39 can crash. Similarly, in the example shown in Figure 6, the brackets 53 must extend all along the side walls 52, 54 if it is desired to seal the volume 51 of the recess 50.

The use of the seal makes it possible to easily seal air volumes that were not initially, such as industrial premises, including prefabricated panels, sandwich panels, metal constructions, etc. The seal or seals allow insulation in the air, favorable to the air conditioning of a room. It is then possible to use the removable wall according to the invention as an air-conditioning technical jacket. Thus, for example, it is possible to mount a vertical frame in a part that it is desired to divide, so that said frame has fastening elements on which two removable walls according to the invention can be clipped, so as to to face each other. An internal volume is provided between the two removable walls fixed on either side of the frame. This volume can be used as a technical duct, for example to house an air conditioner, which is accessible from both sides of the vertical partition thus formed. It is also possible to incorporate insulating elements in said internal volume, in order to have volumes, on either side of the vertical partition, thermally independent. With the removable walls according to the invention, it is therefore possible to quickly and reversibly partition a given volume into several sub volumes.

FIG. 4 shows another example of the use of a removable wall 30 formed of the profile 31 and of the suspended false ceiling 32. The removable wall 30 covers a false slab ceiling 1, 2 whose slabs 1, 2 are supported. by a suspension element 3 in T as described in Figure 1. Staples 20 are mounted on the sides of the T-suspension 3. A seal 39 is also crushed between the outer surface of the horizontal tab 38 and the lower wall 6 of the T suspension 3, ensuring the tightness of the volume V formed between the slabs 1, 2 of the slab ceiling and the removable wall 30 covering said false slab ceiling 1, 2.

Again, the distance d between two edges 33 of the flat surface 32 of the removable wall 30 is very small compared to the distance D that there was with the solutions of the state of the art. Thus, the suspension 3 T is almost invisible when looking at the removable wall 30 covering the false ceiling 1, 2.

In Figure 5 is shown, seen from above, a false slab ceiling covered by removable walls 30 according to the invention. Specifically in the upper part of Figure 5, four removable walls 30 are used to cover four slabs of the same dimensions, while a single removable wall 30 is used, as shown at the bottom of Figure 5, to cover four other adjacent slabs. Indeed, in accordance with the invention, it is possible to use removable walls 30 of variable dimensions, depending on the needs or wishes of the users.

In the example shown in the upper part of Figure 5, there is a clip 20 on each suspension element 3 T framing the slab 1, 2 to cover, so as to be able to clip a removable wall 30. The seal sealing 39 runs over the entire contour of the flat surface 32 and the corresponding suspension 3 T.

In the lower part of FIG. 5, on the other hand, staples 20 are mounted on the suspensions 3 in T flanking the outer edges of the four slabs to be covered by the same removable wall 30. According to the dimensions of the removable wall 30 used, and therefore the dimensions of the surface to be covered, it uses more or less staples 20. Similarly, if the removable wall 30 used to a greater thickness at one place than another, it can also be taken into account in the provision and the number of staples used. The profile of the removable wall 30 is clipped into said staples 20, so that the same plane surface 32 covers the four adjacent slabs. Again, the seal 39 follows a contour of the profile and thus the outer contour of the four adjacent slabs covered by the same removable wall 30. Advantageously, the removable wall according to the invention is removable at will. In particular, in the case where resilient clips 20 are used, disassembly is easily achieved by means of a pull tab. For this, the pull tab is inserted in the space d (FIGS. 1 and 4) between the edges 11, 33 of two adjacent walls 30, or in the space between the edge of the wall 33 and the edge 45 of the surface 44 on which it is fixed (Figure 2), so as to come to press the secondary lug 24 of the clip 20, thereby disengaging the horizontal lug 12, 38 of the lower housing 22. In addition, in the case where the frame is provided with a seal 39, the zipper crushes said seal 39 against the edge of the covered surface considered. The seal 39 elastically pushes the profile 31, or the frame, of the housing 22 so as to disengage the entire removable wall of the staples 20. The removable wall according to the invention can equally well be used to cover any surface, that it's a ceiling, a wall, a niche in a ceiling, a wall, or even stalls. The flat surface of the removable wall may for example be a stretched canvas, forming a billboard or a metal panel for insulating fire or slab Placo, wood or any other material. The removable wall according to the invention can extend vertically, horizontally or at an angle.
