Definitions

• FALSE CEILING INCLUDING PANEL MOUNTING MEANS (X) AND METHOD FOR PRODUCING SUCH A FALSE CEILING
• the invention relates to the field of false walls, and in particular that of suspended ceilings.
• the invention relates more particularly to a false ceiling comprising a supporting structure that can carry a stretched canvas and at least one panel such as a light panel.
• Suspended suspended ceilings are made in conventional manner using rails and removable flat slabs with a stretched canvas. More specifically, rows of rails are arranged in two perpendicular directions so as to define a grid. The slabs are arranged in support on the rails, between each row of the rails.
• the ceilings are already provided with a structure in the form of parallel rails and equidistant opposite for the fixing of technical elements or their passage.
• the realization of a false ceiling, including the establishment of rails for supporting the panels or slabs, is then constrained by the presence of existing rails and the transverse distance separating them from each other. It is therefore necessary to fix beforehand the profiles intended to receive the canvas stretched on the existing rails to come then fix the fabric on them and thus form the slab.
• Each retaining profile comprises means for hanging on one of the smooth body and an elastic arm exerting on the panel a thrust such that the panel is kept pressed against a bearing area of the body of the rail.
• the invention aims to remedy these problems by providing a false ceiling and a method of installation to solve the problems referred to above.
• the invention aims to provide a false ceiling providing a quick and easy installation and removal, easy and safe a panel while limiting the shadow on the canvas when the panel is a illuminated sign.
• the invention provides a false ceiling comprising a bearing structure comprising at least two opposed profiles coplanar and parallel to each other fixed on a ceiling, these sections defining between them an opening of access to the ceiling, each profile comprising a shoulder defining a horizontal bearing surface facing the ceiling, at least one panel disposed between the profiles, the panel being dimensioned to rest on the bearing surface of the profiles, the false ceiling comprising in addition to removable and reported means of transverse wedging of the panel between two profiles opposed, these wedging means being arranged on either side of the panel.
• the panels are maintained on the shoulders by simple gravity, while being prevented from falling due to improper handling of the latter or their displacement relative to the profiles, and whatever the dimensions of the shoulders on which the panels rest.
• the wedging means may also have the advantage of ensuring a centered positioning of the panels relative to the profiles.
• each wedging means are placed in vertical support on the bearing surfaces of the profiles.
• each wedging means is interposed transversely between a lateral edge of the panel and a vertical bearing face of an associated section oriented towards the opposite section.
• the wedging means have a nominal transverse width established according to the width of the panel and the width of the access opening to the ceiling so as to prevent a transverse displacement of the panel such as one of the side edges of the panel is positioned in front of the passage opening, the panel having a width greater than the access opening width of the ceiling.
• the wedging means are thus arranged to prevent transverse displacement of the panel on the profiles, except a necessary clearance to allow a quick installation of the panel on the profiles and their removal by simple push.
• each wedging means is a wedging bar whose elongate body is in vertical support along a bearing surface of an associated profile, and which is interposed transversely between a lateral edge of the panel and a vertical bearing face of the associated section facing the opposite profile.
• the wedging bar comprises at least one elongate flat bottom face adapted to be supported along a bearing surface of an associated section.
• the wedging bar is of rectangular or square cross section so as to comprise two opposite elongate flat side walls capable of being interposed transversely between a lateral edge of the panel and a vertical bearing face of the associated profile facing the opposite profile.
• the shoulders of the profiles define a bearing surface having a transverse width greater than or equal to 5 millimeters so as to limit the shadow on the fabric placed under the panel when the latter is a light panel while ensuring the maintenance of the panel via the presence of the locking means.
• the bearing surfaces of the profiles are located at the same height.
• the profiles of triangular section have a notch formed in the upper part, the intersection of two faces of the notch defining the shoulder.
• the panel comprises luminous means.
• the false ceiling comprises a stretched fabric fixed in the lower part of the profiles, extending parallel to the panel.
• the invention also relates to a method for installing a panel on a ceiling provided with an existing structure for the realization of a false ceiling, the existing structure comprising at least two opposite rails, coplanar and parallel to each other, the method comprising the steps of:
• each profile defining with the profile fixed to a opposite rail a ceiling access opening, each section comprising a shoulder defining a horizontal bearing surface facing the ceiling,
• step b) placement is performed before or after step b) insertion.
• the method comprises a step d) of placing at least one other removable securing means attached to a bearing surface of the other profiles.
• FIG. 1 represents a schematic view of a false ceiling according to an exemplary embodiment of the invention
• Figures 2a and 2b show the steps of placing a panel on the carrier structure to form the false ceiling shown in Figure 1.
• a false ceiling 1 comprising a supporting structure 2, at least one panel 3, preferably bright, a stretched fabric 5 and means for wedging the panel 3 on the supporting structure 2 .
• the carrier structure 2 comprises a series of profiles 20, 21 parallel to each other, and preferably equidistant from each other, fixed on a ceiling 4. In the example shown, only two transversely opposed sections 20, 21 are shown. .
• the profiles 20, 21 are fixed to the ceiling 4 via rails 6 carried by the ceiling 4. As will be seen below, when describing the installation of the light panel 3, these rails are part of an existing structure of the ceiling .
• each section 20, 21, of triangular section has a horizontal upper surface 200, 210, the other two surfaces defining an inner surface 201, 211 inclined and a vertical outer surface 202, 212 of the structure carrier 2.
• each profile 20, 21 comprises a notch 7 at right angles, extending along the profile 20 , 21.
• the notch 7 extends over the entire length of the profile 20, 21.
• the notch 7 is thus in the form of a longitudinal groove section right angle similar to an "L" profile.
• each section 20, 21 has a notch 7 arranged to define a shoulder having a horizontal bearing surface 8 defining a horizontal bearing plane oriented towards the ceiling 4.
• the bearing surfaces 8 of each of the profiles 20, 21 extend in the same plane parallel to the plane of the ceiling 4.
• the panel 3 is sized to rest on the horizontal bearing surface 8 of each section 20, 21.
• it has a transverse width greater than the transverse width "D" of the opening of access to the ceiling, which, in the illustrated embodiment, corresponds to the distance D between the free edges vis-à-vis the shoulders.
• each shoulder has a horizontal bearing surface having a width greater than or equal to 5 millimeters.
• This has the advantage of limiting the shadow on the fabric 5 when the panel 3 carried by the profiles 20, 21 is a light panel. Given the narrowness of the shoulders, the panel 3 rests on them only a few millimeters.
• wedging means 10 are placed on the shoulder of each of the sections 20, 21, between a lateral edge 30 of the panel 3 and a vertical stop face 9 delimiting the notch 7.

• the wedging means 10 here constituted by one or two wedging bars, are dimensioned appropriately.
• each wedging bar 10A, 10B is thus a removable insert component which can be implemented in an associated notch 7.
• each wedging bar comprises at least one flat lower surface 11 which is able to rest vertically on an associated horizontal bearing surface 8.
• Each wedging bar is also delimited by two opposite vertical lateral faces 12 and 13.
• the external vertical lateral face In position in a notch 7, and after assembly of the panel 3, the external vertical lateral face is facing or in contact with a vertical surface 9, while the internal vertical face 13 is screwed-to -vis or in contact with a side edge 30 of the panel 3.
