Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention concerne le domaine des fausses-parois, et en particulier celui des faux-plafonds suspendus.The invention relates to the field of false walls, and in particular that of suspended false ceilings.

L'invention concerne plus particulièrement un faux-plafond comprenant une structure porteuse pouvant porter une toile tendue et au moins un panneau tel qu'un panneau lumineux.The invention relates more particularly to a false ceiling comprising a load-bearing structure capable of carrying a stretched canvas and at least one panel such as a light panel.

ETAT DE LA TECHNIQUESTATE OF THE ART

Il est connu d'utiliser les faux plafonds pour cacher dans un local des éléments techniques tels que des câbles électriques, des tuyaux, etc.It is known practice to use false ceilings to hide technical elements such as electric cables, pipes, etc. in a room.

Les faux plafonds suspendus sont réalisés de manière classique à l'aide de rails et de dalles planes amovibles portant une toile tendue. Plus spécifiquement, des rangées de rails sont disposées suivant deux directions perpendiculaires de sorte à définir un quadrillage. Les dalles sont disposées en appui sur les rails, entre chacune des rangés des rails.The suspended suspended ceilings are made in the classic way using rails and removable flat slabs carrying a stretched canvas. More specifically, rows of rails are arranged in two perpendicular directions so as to define a grid. The slabs are placed resting on the rails, between each of the rows of the rails.

Dans certains bâtiments cependant, il peut s'avérer que les plafonds soient déjà pourvus d'une structure se présentant sous la forme de rails parallèles et opposés équidistants pour la fixation d'éléments techniques ou leur passage. La réalisation d'un faux-plafond, et notamment la mise en place des rails destinés à supporter les panneaux ou dalles, est alors contrainte par la présence des rails existants ainsi que par la distance transversale séparant ces derniers les uns par rapport aux autres. Il est donc nécessaire de venir fixer au préalable les profilés destinés à recevoir la toile tendue sur les rails existants pour venir ensuite fixer la toile sur ces derniers et ainsi former la dalle.In some buildings, however, it may be that the ceilings are already provided with a structure in the form of parallel and opposite rails equidistant for the fixing of technical elements or their passage. The production of a false ceiling, and in particular the installation of the rails intended to support the panels or slabs, is then constrained by the presence of the existing rails as well as by the transverse distance separating the latter from one another. It is therefore necessary to come and fix the profiles intended to receive the canvas stretched on the existing rails beforehand in order to then fix the canvas on the latter and thus form the slab.

Se pose alors le problème de l'installation d'une dalle devant inclure un panneau. Dans certains cas en effet, des panneaux pourvus de moyens lumineux, tels que des diodes électroluminescentes, des panneaux isolants, ou bien tout autre panneau convenant à la fonctionnalité attendue de la dalle, sont intégrés dans celle-ci de manière fixe.The problem then arises of installing a slab to include a panel. In certain cases, in fact, panels provided with light means, such as light-emitting diodes, insulating panels, or indeed any other panel suitable for the functionality expected of the panel, are integrated in the latter in a fixed manner.

Un exemple d'une telle dalle est décrit dans la demande WO2014/131988 .An example of such a slab is described in the application WO2014 / 131988 .

Le fait de devoir fixer les profilés sur les rails existant préalablement impose que les panneaux aient un caractère amovible afin de permettre l'accès dans l'espace ménagé entre le plafond et la dalle. Le problème technique qui se pose est donc de monter un panneau entre deux profilés parallèles déjà installés et d'assurer sa retenue entre les profilés tout en conférant à ce dernier un caractère amovible. A ce problème s'ajoute celui d'assurer un rendu esthétique satisfaisant lorsque le panneau amovible à installer est un panneau lumineux. Il convient en effet de limiter autant que possible toute ombre portée sur la toile disposée au-dessous du panneau lumineux.The fact of having to fix the profiles on the existing rails beforehand requires that the panels have a removable character in order to allow access to the space provided between the ceiling and the slab. The technical problem which arises is therefore to mount a panel between two parallel profiles already installed and to ensure its retention between the profiles while giving the latter a removable character. To this problem is added that of ensuring a satisfactory aesthetic rendering when the removable panel to be installed is a light panel. It is in fact advisable to limit as much as possible any shadow cast on the canvas placed below the light panel.

On connaît également de la demande de brevet DE102014113059 un faux plafond comportant un panneau fixé sur deux corps de lisse au moyen de profilés de maintien élastiques. Chaque profilé de maintien comporte des moyens d'accroche sur l'un des corps de lisse ainsi qu'un bras élastique exerçant sur le panneau une poussée telle que le panneau est maintenu plaqué sur une zone d'appui du corps de lisse. Cette solution ne peut être mise en œuvre aisément dans le cadre de l'utilisation de rails et de profilés d'ores et déjà installés sur des murs ou parois. De plus les manœuvres de mise en place du panneau sont rendues difficiles par la nécessité d'appliquer un effort transversal de compression du bras élastique.Also known from the patent application DE102014113059 a false ceiling comprising a panel fixed to two rail bodies by means of elastic retaining profiles. Each retaining section comprises means for hooking onto one of the stringer bodies as well as an elastic arm exerting a thrust on the panel such that the panel is kept pressed against a bearing zone of the stringer body. This solution cannot be easily implemented in the context of the use of rails and profiles already installed on walls or walls. In addition, the panel positioning maneuvers are made difficult by the need to apply a transverse compressive force of the elastic arm.

On connaît également de la demande de brevet DE 91 09 410 U1 un faux-plafond dont le panneau est coincé sans jeu entre les montants verticaux des cornières de retenue et des bandes intumescentes fixée sur ces montants verticaux; dans cette demande le panneau ne repose pas sur le montant vertical des cornières de retenue.We also know of the demand for patent DE 91 09 410 U1 a false ceiling, the panel of which is wedged without play between the vertical uprights of the retaining angles and of the intumescent strips fixed to these vertical uprights; in this application the panel does not rest on the vertical upright of the retaining angles.

L'invention vise à remédier à ces problèmes en proposant un faux plafond et un procédé d'installation permettant de résoudre les problématiques visées ci-dessus.The invention aims to remedy these problems by proposing a false ceiling and an installation method making it possible to solve the problems referred to above.

Ainsi, l'invention a pour objet de proposer un faux plafond offrant une mise en place et un retrait rapide, aisé et en toute sécurité d'un panneau tout en limitant l'ombre portée sur la toile lorsque le panneau est un panneau lumineux.Thus, the object of the invention is to provide a false ceiling offering rapid, easy and safe installation and removal of a panel while limiting the shadow cast on the canvas when the panel is a light panel.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

A cet effet, et selon un premier aspect, l'invention propose un faux-plafond selon l'objet de la revendication 1.To this end, and according to a first aspect, the invention provides a false ceiling according to the subject of claim 1.

Grâce à la présence des moyens de calage et leur arrangement, les panneaux sont maintenus sur les épaulements par simple gravité, tout en étant empêché de chuter suite à une mauvaise manipulation de ces dernières ou à leur déplacement par rapport au profilés, et ce quelles que soient les dimensions des épaulements sur lesquels les panneaux reposent. Les moyens de calage pouvant aussi présenter l'avantage d'assurer un positionnement centré des panneaux par rapport aux profilés.Thanks to the presence of the wedging means and their arrangement, the panels are held on the shoulders by simple gravity, while being prevented from falling due to improper handling of the latter or their displacement with respect to the profiles, and whatever or the dimensions of the shoulders on which the panels rest. The wedging means can also have the advantage of ensuring a centered positioning of the panels relative to the profiles.

Les moyens de calage sont posés en appui vertical sur les surfaces d'appui des profilés.The wedging means are placed in vertical support on the bearing surfaces of the profiles.

Chaque moyen de calage est interposé transversalement entre un bord latéral du panneau et une face d'appui verticale d'un profilé associé orientée vers le profilé opposé.Each wedging means is interposed transversely between a lateral edge of the panel and a vertical bearing face of an associated profile oriented towards the opposite profile.

Les moyens de calage présentent une largeur transversale nominale établie en fonction de la largeur du panneau et de la largeur de l'ouverture d'accès au plafond de sorte à empêcher un déplacement transversal du panneau tel que l'un des bords latéraux du panneau vienne se positionner face à l'ouverture de passage, le panneau présentant une largeur supérieure à la largueur d'ouverture d'accès au plafond. Les moyens de calage sont ainsi agencés pour empêcher un déplacement transversal du panneau sur les profilés, hormis un jeu nécessaire pour permettre une mise en place rapide du panneau sur les profilés et leur retrait par simple poussée.The wedging means have a nominal transverse width established as a function of 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 that one of the side edges of the panel comes. position themselves facing the passage opening, the panel having a width greater than the width of the ceiling access opening. The wedging means are thus arranged to prevent transverse movement of the panel on the profiles, apart from a clearance necessary to allow rapid positioning of the panel on the profiles and their removal by simple pushing.

Chaque moyen de calage est une barre de calage dont le corps allongé est en appui vertical le long d'une surface d'appui d'un profilé associé, et qui est interposée transversalement entre un bord latéral du panneau et une face d'appui verticale du profilé associé orientée vers le profilé opposé.Each wedging means is a wedging bar, the elongate body of which rests vertically along a bearing surface of an associated section, and which is interposed transversely between a lateral edge of the panel and a vertical bearing face of the associated profile oriented towards the opposite profile.

Avantageusement, la barre de calage comporte au moins une face inférieure plane allongée apte à être en appui le long d'une surface d'appui d'un profilé associé.Advantageously, the wedging bar comprises at least one elongated flat lower face capable of being supported along a bearing surface of an associated section.

Avantageusement, la barre de calage est de section transversale rectangulaire ou carrée de manière à comporter deux parois latérales planes allongées opposées aptes à être interposées transversalement entre un bord latéral du panneau et une face d'appui verticale du profilé associé orientée vers le profilé opposé.Advantageously, the wedging bar has a rectangular or square cross section so as to include two opposite elongate flat side walls capable of being interposed transversely between a side edge of the panel and a vertical bearing face of the associated profile oriented towards the opposite profile.

Avantageusement, les épaulements des profilés définissent une surface d'appui présentant une largeur transversale supérieure ou égale à 5 millimètres de sorte à limiter l'ombre portée sur la toile placée sous le panneau lorsque ce dernier est un panneau lumineux tout en assurant le maintien du panneau via la présence des moyens de blocage.Advantageously, 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 cast on the canvas 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.

Avantageusement, les surfaces d'appui des profilés sont situées à la même hauteur.Advantageously, the bearing surfaces of the profiles are located at the same height.

Avantageusement, les profilés, de section triangulaire, comportent une encoche ménagée en partie supérieure, l'intersection de deux faces de l'encoche définissant l'épaulement.Advantageously, the profiles, of triangular section, include a notch formed in the upper part, the intersection of two faces of the notch defining the shoulder.

Avantageusement, le panneau comporte des moyens lumineux.Advantageously, the panel comprises light means.

Avantageusement, le faux-plafond comporte une toile tendue fixée en partie inférieure des profilés, s'étendant parallèlement au panneau.Advantageously, the false ceiling comprises a stretched canvas fixed in the lower part of the profiles, extending parallel to the panel.

L'invention concerne aussi un procédé selon la revendication 9 pour installer un panneau sur un plafond pourvu d'une structure existante pour la réalisation d'un faux-plafond.The invention also relates to a method according to claim 9 for installing a panel on a ceiling provided with an existing structure for producing a false ceiling.

Il peut être prévu que l'étape c) de placement soit réalisée avant ou après l'étape b) d'insertion.Provision can be made for the placement step c) to be carried out before or after the insertion step b).

Avantageusement, le procédé comporte une étape d) consistant à placer au moins un autre moyen de calage amovible rapporté sur une surface d'appui de l'autre des profilés.Advantageously, the method comprises a step d) consisting in placing at least one other removable wedging means attached to a bearing surface of the other of the profiles.

Dans l'exemple illustré, seuls deux profilés transversalement opposés 20, 21 sont représentés. Les profilés 20, 21 sont fixés au plafond 4 via des rails 6 portés par le plafond 4. Comme on le verra plus loin, lors de la description de l'installation du panneau lumineux 3, ces rails relèvent d'une structure existante du plafond.The supporting structure 2 comprises a series of sections 20, 21 parallel to each other, and preferably equidistant from each other, fixed to a ceiling 4. In the example illustrated, 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 later, during the description of the installation of the light panel 3, these rails fall under an existing structure of the ceiling. .

Ils sont symétriques l'un par rapport à l'autre et sont agencés entre eux de manière à définir une ouverture d'accès au plafond 4 de largeur transversale « D ».The profiles 20, 21 are coplanar and extend parallel to one another. They are symmetrical with respect to one another and are arranged between them so as to define an access opening to the ceiling 4 of transverse width "D".

Dans le mode de réalisation décrit, chaque profilé 20, 21, de section triangulaire, présente une surface supérieure horizontale 200, 210, les deux autres surfaces définissant une surface interne 201, 211 inclinée et une surface externe verticale 202, 212 de la structure porteuse 2.In the embodiment described, each section 20, 21, of triangular section, has a horizontal upper surface 200, 210, the other two surfaces defining an internal surface 201, 211 inclined and a vertical external surface 202, 212 of the structure. carrier 2.

On entend par surface interne d'un profilé 20, 21, la surface orientée du côté de l'ouverture d'accès et faisant face à l'autre profilé opposé, et par surface externe, la surface opposée à la surface interne.By internal surface of a section 20, 21 is meant the surface oriented on the side of the access opening and facing the other opposite section, and by external surface, the surface opposite to the internal surface.

Au niveau de la jonction de la surface supérieure 200, 210 et la surface interne 201, 211 du profilé 20, 21, chaque profilé 20, 21 comporte, une encoche 7 à angle droit, s'étendant le long du profilé 20, 21. Préférentiellement, l'encoche 7 s'étend sur toute la longueur du profilé 20, 21.At the junction of the upper surface 200, 210 and the internal surface 201, 211 of the profile 20, 21, each profile 20, 21 comprises a notch 7 at right angles, extending along the profile 20, 21. Preferably, the notch 7 extends over the entire length of the profile 20, 21.

L'encoche 7 se présente ainsi sous la forme d'une rainure longitudinale à section en angle droit analogue à un profilé en « L ».The notch 7 thus takes the form of a longitudinal groove with a right-angled section similar to an "L" profile.

L'encoche 7 définit un épaulement sur laquelle le panneau 3 va prendre appui verticalement vers le bas aux fins de son installation sur les profilé 20, 21. Dans le mode de réalisation illustré, chaque profilé 20, 21 comporte une encoche 7 arrangée pour définir un épaulement présentant une surface d'appui horizontale 8 définissant un plan d'appui horizontal orienté vers le plafond 4. Les surfaces d'appui 8 de chacun des profilés 20, 21 s'étendent dans un même plan parallèle au plan du plafond 4.The notch 7 defines a shoulder on which the panel 3 will bear vertically downward for the purposes of its installation on the profiles 20, 21. In the illustrated embodiment, each profile 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.

Pour ce faire, le panneau 3 est dimensionné pour reposer sur la surface d'appui horizontale 8 de chaque profilé 20, 21. Ainsi, il présente une largeur transversale supérieure à la largeur transversale « D » de l'ouverture d'accès au plafond, laquelle, dans le mode de réalisation illustré, correspond à la distance D séparant les bords libres en vis-à-vis des épaulements.To do this, the panel 3 is sized to rest on the horizontal bearing surface 8 of each section 20, 21. Thus, it has a transverse width greater than the transverse width "D" of the ceiling access opening. , which, in the illustrated embodiment, corresponds to the distance D separating the free edges facing the shoulders.

De manière préférée, chaque épaulement présente une surface d'appui horizontale ayant une largeur supérieure ou égale à 5 millimètres. Cela a pour avantage de limiter l'ombre portée sur la toile 5 lorsque le panneau 3 porté par les profilés 20, 21 est un panneau lumineux. Compte tenu de l'étroitesse des épaulements, le panneau 3 ne repose sur ces derniers que sur quelques millimètres. Afin d'éviter que le panneau 3 ne se décale transversalement, et donc ne chute n'étant car n'étant plus maintenu au niveau de l'un des épaulements, des moyens de calage 10 sont placés sur l'épaulement de chacun des profilés 20, 21, entre une bordure latérale 30 du panneau 3 et une face verticale d'arrêt 9 délimitant l'encoche 7.Preferably, 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 cast on the canvas 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 for only a few millimeters. In order to prevent the panel 3 from shifting transversely, and therefore not falling because it is no longer maintained at the level of one of the shoulders, wedging means 10 are placed on the shoulder of each of the profiles. 20, 21, between a lateral edge 30 of the panel 3 and a vertical stop face 9 delimiting the notch 7.

Autrement dit, chaque encoche 7 est délimitée par une surface d'appui horizontale 8, et une surface verticale d'appui ou d'arrêt 9.In other words, each notch 7 is delimited by a horizontal support surface 8, and a vertical support or stop surface 9.

Dans l'exemple décrit, chaque moyen de calage 10 consiste en une barre allongée de calage 10A, 10B.In the example described, each wedging means 10 consists of an elongated wedging bar 10A, 10B.

Chaque barre de calage est par exemple une barre allongée rectiligne de section rectangulaire ou carrée.Each wedging bar is for example an elongated rectilinear bar of rectangular or square section.

Afin d'assurer le maintien du panneau 3 en place sur la structure porteuse 2, en empêchant le déplacement transversal du panneau 3 par rapport aux profilés 20, 21, ou du moins en laissant seulement un jeu ne permettant pas que le panneau 3 ne se déporte transversalement vers un des profilés 20, 21 avec un risque de désengagement au niveau du profilé opposé 21, 20, les moyens de calage 10, ici constitués par une ou deux barres de calage, sont dimensionnés de manière appropriée.In order to ensure that the panel 3 is held in place on the supporting structure 2, by preventing the transverse displacement of the panel 3 with respect to the profiles 20, 21, or at least by leaving only a play which does not allow the panel 3 to come together. offset transversely towards one of the sections 20, 21 with a risk of disengagement at the level of the opposite section 21, 20, the wedging means 10, here constituted by one or two wedging bars, are appropriately sized.

Chaque barre de calage 10A, 10B est ainsi un composant rapporté amovible qui peut être mis en place dans une encoche 7 associée.Each wedging bar 10A, 10B is thus a removable insert component which can be placed in an associated notch 7.

A cet effet, chaque barre de calage comporte au moins une surface inférieure plane 11 qui est apte à reposer verticalement sur une surface d'appui horizontale associée 8.To this end, each wedging bar comprises at least one flat lower surface 11 which is able to rest vertically on an associated horizontal support surface 8.

Chaque barre de calage est aussi délimitée par deux faces latérales verticales opposées 12 et 13.Each wedging bar is also delimited by two opposite vertical side faces 12 and 13.

En position dans une encoche 7, et après montage du panneau 3, la face latérale verticale externe est en vis-à-vis ou en contact avec une surface verticale 9, tandis que la face verticale interne 13 est en vis-à-vis ou en contact avec un bord latéral 30 du panneau 3.In position in a notch 7, and after mounting the panel 3, the external vertical side face is opposite or in contact with a vertical surface 9, while the internal vertical face 13 is opposite or in contact with a side edge 30 of the panel 3.

La mise en place du panneau 3 sur la structure porteuse 2 s'effectue de la manière suivante (les mouvements mis en œuvre aux fins de l'installation du panneau 3 sont représentés par des flèches en trait plein).The installation of the panel 3 on the supporting structure 2 is carried out as follows (the movements implemented for the purposes of installing the panel 3 are represented by arrows in solid lines).

En premier lieu, des premiers moyens de calage constitués par une première barre de calage 10A sont installés dans l'encoche 7 de l'un 21 des profilés 20, 21, sur la surface d'appui horizontale 8 correspondante pou associée..First, first wedging means constituted by a first wedging bar 10A are installed in the notch 7 of one 21 of the profiles 20, 21, on the corresponding horizontal bearing surface 8 louse associated.

Le panneau 3 est alors inséré dans l'espace délimité entre le plafond 4 et la structure porteuse 2 au travers de l'ouverture d'accès en étant introduit et placé en biais comme illustré à la figure 2a.The panel 3 is then inserted into the space delimited between the ceiling 4 and the supporting structure 2 through the access opening, being introduced and placed at an angle as illustrated in figure 2a .

Lorsque le panneau 3 est suffisamment remonté dans l'espace, il est pivoté vers le haut, en prenant appui sur le bord périphérique interne libre de la surface d'appui horizontale 8 (pivotement autour de l'axe formé par le bord périphérique) pour le placer dans une position sensiblement horizontale, puis pour glisser ce dernier vers la barre de calage 10A préalablement installée sur le profilé 21 (figure 2a : mouvement des flèches situées à droite ; figure 2b : mouvement des flèches situées à droite).When the panel 3 is sufficiently raised in space, it is pivoted upwards, resting on the free internal peripheral edge of the horizontal bearing surface 8 (pivoting around the axis formed by the peripheral edge) to place it in a substantially horizontal position, then to slide the latter towards the wedging bar 10A previously installed on the profile 21 ( figure 2a : movement of the arrows on the right; figure 2b : movement of the arrows on the right).

Le côté 30 du panneau 3 opposé à la barre de calage 10A est ensuite soulevé au-dessus des de la structure porteuse 2 afin d'installer des second moyens de calage constitués ici par une seconde barre de calage 10B sur la surface d'appui horizontale 8 du profilé 20. Une fois la seconde barre de calage 10B installée, le côté 30 du panneau 3 est redescendu pour venir reposer sur la surface d'appui horizontale 8 associée (figure 2b : mouvement de la flèche située à gauche).The side 30 of the panel 3 opposite to the wedging bar 10A is then raised above the supporting structure 2 in order to install second wedging means constituted here by a second wedging bar 10B on the horizontal bearing surface. 8 of profile 20. Once the second wedging bar 10B has been installed, side 30 of panel 3 is lowered to rest on the associated horizontal support surface 8 ( figure 2b : movement of the arrow on the left).

On comprend que l'on procèdera de la même manière, mais en sens inverse, pour retirer le panneau 3 de la structure porteuse 2.We understand that we will proceed in the same way, but in the opposite direction, to remove the panel 3 from the supporting structure 2.

Ainsi, pour procéder à la mise en place d'un panneau ou dalle 3 en une seule ou plusieurs parties, l'installateur peut disposer d'un jeu de moyens de calage sous la forme par exemple d'un jeu de barres de calage, éventuellement de différentes dimensions (longueur et section transversale) qu'il met en œuvre selon le procédé décrit précédemment.Thus, to proceed with the installation of a panel or slab 3 in one or more parts, the installer can have a set of wedging means in the form for example of a set of wedging bars, possibly of different dimensions (length and cross section) that it implements according to the method described above.

L'invention est décrite dans ce qui précède à titre d'exemple. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de réalisation de l'invention sans pour autant sortir du cadre de l'invention.The invention is described in the foregoing by way of example. It is understood that a person skilled in the art is in a position to produce various variant embodiments of the invention without, however, departing from the scope of the invention.

Ainsi, par exemple, chaque panneau 3 peut être constitué par plusieurs éléments, par exemple des dalles, adjacents, mais tous de la même largeur transversale.Thus, for example, each panel 3 can be formed by several elements, for example tiles, adjacent, but all of the same transverse width.

De même chaque barre de calage peut être en une seule pièce sur toute la longueur nécessaire, ou en plusieurs éléments mis en places adjacents et dans le prolongement longitudinal les uns des autres.Likewise, each wedging bar can be in a single piece over the entire necessary length, or in several elements placed adjacent and in the extension. longitudinal from each other.
