Description

Technical area

The present invention relates to the field of false walls such as false ceilings and false walls and in particular those constituted by a flexible sheet stretched attached along its edges to a support fixed to the walls or to the ceiling of a room of a size. building.

Stretch false ceilings are already known which comprise, on the one hand, a frame fixed to the walls or to the ceiling of a room, this frame being formed by an outer rail itself made up of butted profiles, and on the other hand, a sheet. flexible stretched inside this frame, this flexible sheet consisting of a sheet of plastic material or a canvas. The flexible sheet is kept taut due to the attachment, on the stringer, of an edge integral with the sheet forming a harpoon, this edge having in cross section the shape of a hook coming to grip on a shoulder s' extending over the entire periphery of the outer flange of the stringer.

These known false walls are based on the principle of placing the flexible sheet under tension on the frame, in a perfectly flat manner, horizontally or vertically depending on whether it is a false ceiling or a false wall.

These false ceilings or false walls, once mounted on their rail necessarily let appear a sometimes significant play and therefore visible between the periphery of the stretched wall and the walls supporting the hanging rails. This functional play necessarily results from the need to provide sufficient space between the wall and the taut surface to insert the peripheral hooks of the sheet inside the stringers so that the end bead of the harpoon fits into place. on a shoulder provided for this purpose on the outer flange of the closest rail.

In many cases, this residual space between the tablecloth and the wall can be visually disturbing because it constitutes a hollow joint giving a sometimes very unsightly impression; this is the case in particular when the canvases are stretched in rooms of water where the wall and the ceiling should not have any hollow joint to obtain a better presentation; Likewise, in many installations it is important that the hollow joint between the fabric and the walls be as small as possible in order to avoid untimely air passages which generate dirt or which may unbalance certain ventilation installations.

Although many changes made in the field of beams have made it possible to reduce the residual space and improve the aesthetic appearance of these false walls, they are still difficult to integrate into classic environments such as old buildings in which cornices are usually placed at the interface between walls and ceilings

Such fixing devices known from the state of the art are for example described in FR 2 767 851 A1 , EP 1 746 215 A1 , US 5,581,966 A and WO 02/06604 A1 .

Summary of the invention

The object of the present invention is therefore to overcome such drawbacks by proposing a system for fixing a stretched wall, for example a ceiling between two walls, allowing the rapid and simple integration of a cornice at the interface between the walls and the wall. ceiling.

According to a preferred embodiment, the device according to the invention consists of PVC and / or aluminum. Even more preferably, said rail is made of aluminum and said cornice of PVC.

Benefits provided

The device according to the invention, by associating a rail having a longitudinal groove and a cornice having fixing means which can be inserted into said groove, offers the possibility of quickly fixing a cornice to a false ceiling. Said cornice also makes it possible to hide the rail and the possible gap between the flexible sheet and the adjacent wall. In addition, the separation of the rail and the cornice allows the use of different shapes of cornices depending on the desired aesthetic effect.

Description of the embodiments

By reference to figures 1 , 2 , 3 and 4 , the fixing device 1, intended in particular to hold false ceilings and false walls and in particular those constituted by a flexible sheet stretched hooked along its edges, comprises a rail 2 consisting of a first wing 3 intended to be fixed on the wall perpendicular to the flexible tablecloth. Said wing 3 comprises a bearing face 4 which is in contact with the wall and a free face 5 which faces said flexible sheet.

Said bearing face 4 does not necessarily extend over the entire width of the first wing 3. It is thus possible to envisage using a first wing 3 whose face facing the wall is not completely flat.

The stringer 2 also comprises a second wing 6, fixed to the first wing 3 and more particularly to the free face 5. The two wings 3, 6 are preferably made in one piece. The second wing 6 preferably extends perpendicularly to the first wing 2 and comprises a hooking means 7 intended to cooperate with the edges of the flexible sheet. This attachment means preferably has the form of a hook or a shoulder on which the harpoon present at the periphery of the flexible sheet comes to rest. The attachment means 7 can also take any other form known to those skilled in the art. Among these, we can in particular mention the eyelets which will make it possible to fix the flexible sheet via a lace associated with the periphery thereof. The second wing 6 defines the limit between the upper part and the lower part of said stringer. More precisely, the part of the beam 2 located under said second wing 6, when the beam 2 is fixed to the wall, is designated as being the lower part of the beam 2. Conversely, the part of the beam 2 located above said second wing 6, when the beam 2 is fixed to the wall, is designated as the upper part of the beam 2

The lower part of the rail 2 comprises a longitudinal groove 8 open to the outside of said rail 2. this longitudinal groove 8 can take different shapes. Preferably, it is a longitudinal groove with converging edges in the form of a dovetail. According to the embodiment, also preferred shown in figures 1 , 2 , 3 and 4 , it is a longitudinal groove with converging edges having a straight cut in the shape of a circle, an inverted V or an octagon.

Furthermore, the fixing device 1 also comprises a cornice 9 consisting of a wing 10, one of the faces 11 of which comprises at least one elastically fixing means 12. deformable designed to fit into the longitudinal groove 8.

The face 11 of the wing constituting the cornice 9, comprising the fixing means 12 is the face intended to face the stringer 2. The fixing means 12 can take many forms as long as they are capable of s 'insert and remain inside the longitudinal groove 8. In the particular case where the longitudinal groove 8 has the shape of a dovetail, the elastically deformable fixing means 12 preferably consists of an element whose section right has a greater width at its top than at its base. Thus, the fixing means 12 will be able to be compressed to pass the opening of the longitudinal groove 8 and then relax to ensure the junction between the rail 2 and the cornice 9.

The cornice 9 can take different shapes depending on the desired aesthetic effect. The width of the wing 10 is advantageously chosen to cover the whole of the beam 2. Preferably, the wing 10 has a cross section in the form of an arc of a circle. According to an even more preferred embodiment, the width of said wing 10 is chosen such that one of its longitudinal edges 13 will rest on said flexible sheet and in that the other longitudinal edge 14 will rest on the wall carrying said rail 2. According to an entirely preferred embodiment, the longitudinal edges 13, 14 are elastically deformable so that they will be able to pass from a relaxed position 13, 14 to a compressed position 13 ', 14 'when they are resting on said wall and said flexible sheet.
