Abstract
Description
L'invention se rapporte a une grille pour la construction d'un faux plafond suspendu. The invention relates to a grid for the construction of a suspended false ceiling.
Elle se rapporte également aux faux plafonds pourvus de la dite grille. It also relates to false ceilings provided with said grid.
La réalisation de faux plafonds peut se faire à l'aide de panneaux plans éventuellement perforés ou à l'aide de grilles. False ceilings can be made using flat panels, possibly perforated, or with grids.
En raison de la différence de structure entre un panneau et une grille, les moyens de fixation sont totalement différents. Due to the difference in structure between a panel and a grid, the fixing means are completely different.
L'invention a pour objet exclusivement les faux plafonds à grille. The subject of the invention is exclusively false ceilings with grids.
Classiquement, une grille pour faux plafonds est constituée de profilés qui, parallèles à un axe prédéterminé dit axe de référence, sont maintenues écartés l'un de l'autre par des entretoises perpendiculaires à l'axe de référence précité. Conventionally, a grid for false ceilings consists of profiles which, parallel to a predetermined axis called the reference axis, are kept apart from one another by spacers perpendicular to the above-mentioned reference axis.
Les profilés et les entretoises sont écartés selon un pas prédéterminé en fonction des dimensions transversale et longitudinale de la grille afin que les dimensions soient chacune un multiple du pas considéré. The profiles and spacers are spaced at a predetermined pitch as a function of the transverse and longitudinal dimensions of the grid so that the dimensions are each a multiple of the pitch considered.
Ces grilles sont accrochées sur des porteurs, eux-mêmes suspendus au plafond. These grids are hung on carriers, themselves suspended from the ceiling.
Il existe à ce jour des porteurs pour réaliser deux types de pose, les porteurs visibles et les porteurs invisibles. To date, there are carriers to carry out two types of installation, visible carriers and invisible carriers.
Le procédé de pose varie en fonction du type de porteurs. The installation process varies depending on the type of carriers.
Le premier procédé mettant en oeuvre les porteurs visibles consiste à venir poser la grille au dessus d'une structure porteuse dont la face tournée vers le bas participe à l'aspect visuel. The first method using visible carriers consists of placing the grid above a carrier structure whose face facing down contributes to the visual aspect.
Suivant cette technique, la face apparente des entretoises et des profilés sont dans un même plan et le motif du plafond obtenu est un rectangle ou un carré. According to this technique, the visible face of the spacers and profiles are in the same plane and the pattern of the ceiling obtained is a rectangle or a square.
Par exemple, il est connu d'utiliser comme porteurs des profilés en Té renversé dont les faces des ailes du Té tournées vers le haut servent d'appui pour les bord de la grille. For example, it is known to use inverted tee profiles as carriers, the faces of the wings of the tee facing upwards serving as support for the edges of the grid.
Au lieu d'un profilé en Té, il est connu de faire appel à des profilé en U et l'accrochage des grilles se fait par appui des bords de la grille sur les ailes du U. Instead of a T-shaped profile, it is known to use U-shaped profiles and the grating of the grids is done by pressing the edges of the grid on the wings of the U.
Les éléments porteurs sont agencés sous forme d'un treillis délimitant des ouvertures dans lesquelles sont logées les grilles présentant une maille plus étroite. The supporting elements are arranged in the form of a lattice delimiting openings in which the grids having a narrower mesh are housed.
Le deuxième procédé mettant en oeuvre cette fois-ci des porteurs invisibles consiste à suspendre les grilles sous les porteurs. The second method, this time using invisible carriers, consists in suspending the grids under the carriers.
La face apparente des entretoises est en retrait par rapport à celle des profilés de sorte que le faux plafond semble apparaître comme une succession de profilés parallèles à un axe préférentiel. The visible face of the spacers is set back from that of the profiles so that the false ceiling seems to appear as a succession of profiles parallel to a preferred axis.
Pour l'accrochage de ces grilles, on utilise des suspentes ou épingles ressorts en forme de Vé. For hanging these grids, V-shaped suspension lines or pins are used.
La grille présente au moins un orifice au travers duquel le corps de l'épingle est engagé et le porteur présente un trou oblong dans lequel sont engagées les extrémités des deux branches du Vé qui, en s'écartant, plaquent la grille sous le porteur. The grid has at least one orifice through which the body of the pin is engaged and the carrier has an oblong hole in which are engaged the ends of the two branches of the V which which, moving away, press the grid under the carrier.
Pour obtenir le calage de ces grilles, les éléments porteurs présentent des entailles ouvertes vers la grille pour recevoir les bords libres des entretoises ou profilés. To obtain the setting of these grids, the carrier elements have open notches towards the grid to receive the free edges of the spacers or profiles.
Ainsi, à chaque grille ayant un pas prédéterminé et des largeurs d'entretoise et de profilé déterminées, correspond un seul élément porteur. Thus, each grid having a predetermined pitch and determined spacer and profile widths, corresponds to a single support element.
Au moment du montage, la disposition des porteurs impose automatiquement l'emplacement des grilles. At the time of assembly, the arrangement of the carriers automatically imposes the location of the grids.
Cela est très contraignant. This is very restrictive.
Quel que soit le mode de fixation de ces grilles, pour obtenir une continuité dans le treillis, au lieu que la grille soit bordée par un cadre constitué par les profilés et entretoises dites d'extrémités, les deux entretoises dites d'extrémités ainsi que les deux profilés dits d'extrémités sont en retrait par rapport au bord considéré de la grille d'une valeur correspondant à un demi-pas. Whatever the method of fixing these grids, in order to obtain continuity in the trellis, instead of the grid being bordered by a frame constituted by the so-called end sections and spacers, the two so-called end spacers and the two so-called end sections are set back with respect to the considered edge of the grid by a value corresponding to a half-step.
On obtient ainsi une continuité du motif et de l'écartement des profilés et entretoises. This gives continuity to the pattern and the spacing of the profiles and spacers.
Un des résultats que l'invention vise à obtenir et une grille qui notamment remédie aux inconvénients précités. One of the results that the invention aims to obtain and a grid which in particular remedies the aforementioned drawbacks.
A cet effet, l'invention a pour objet une grille pour faux plafonds comprenant
- des profilés parallèles à un axe prédéterminé, dit axe de référence,
- des entretoises perpendiculaires à l'axe de référence précité maintenant les profilés écartés l'un de l'autre et,
- des moyens de fixation des éléments porteurs, dans laquelle grille, les profilés et entretoises sont écartés selon un pas prédéterminé et laquelle grille présente des dimensions transversale et longitudinale correspondant à des multiple des pas précités, cette grille étant caractérisée en ce que
- les extrémités des profilés de la grille sont réunies par une traverse parallèle aux entretoises et présentant une aile extérieure perpendiculaire au plan de la grille dite aile verticale et une aile parallèle au plan de la dite grille dite aile horizontale,
- la distance entre la traverse et l'entretoise la plus proche est égale au pas entre les entretoises et
- l'aile verticale de cette traverse, d'une part, constitue l'un des bords de la grille et, d'autre part, présente un décrochement local par rapport aux deux plans définissant l'épaisseur de l'aile pour réaliser une zone d'accrochage avec les moyens de fixation, lesquels sont constitués par au moins un tronçon de profilé de section sensiblement en oméga formant une pince saisissant, entre ses mors, l'aile verticale de la traverse.To this end, the invention relates to a grid for false ceilings comprising
- profiles parallel to a predetermined axis, called the reference axis,
- spacers perpendicular to the aforementioned reference axis keeping the sections spaced from one another and,
means for fixing the load-bearing elements, in which grid, the profiles and spacers are spaced apart at a predetermined pitch and which grid has transverse and longitudinal dimensions corresponding to multiples of the aforementioned steps, this grid being characterized in that
the ends of the profiles of the grid are joined by a crosspiece parallel to the spacers and having an outer wing perpendicular to the plane of the grid called the vertical wing and a wing parallel to the plane of the said grid called the horizontal wing,
- the distance between the crosspiece and the nearest spacer is equal to the pitch between the spacers and
- The vertical wing of this cross, on the one hand, constitutes one of the edges of the grid and, on the other hand, has a local offset relative to the two planes defining the thickness of the wing to achieve a attachment zone with the fixing means, which are constituted by at least one section of section profile substantially in omega shape forming a clamp gripping, between its jaws, the vertical wing of the crosspiece.
L'invention a également pour objet le faux plafond pourvu de la dite grille. The invention also relates to the false ceiling provided with said grid.
L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin qui représente schématiquement
- figures 1 et 2 : des vues en perspective d'un plafond,
- figure 3 : une vue en coupe verticale d'un plafond.The invention will be better understood with the aid of the description below given by way of nonlimiting example with regard to the drawing which schematically represents
- Figures 1 and 2: perspective views of a ceiling,
- Figure 3: a vertical sectional view of a ceiling.
En se reportant au dessin, on voit une grille 1 pour faux plafond comprenant
- des profilés 2 parallèles à un axe prédéterminé, dit axe de référence,
- des entretoises 3 perpendiculaires à l'axe 4 de référence précité maintenant les profilés écartés l'un de l'autre et,
- des moyens 6 de fixation des éléments porteurs,
dans laquelle grille, les profilés 2 et entretoises 3 sont écartés selon un pas prédéterminé et laquelle grille présente des dimensions transversale et longitudinale correspondant à des multiples des pas précités.Referring to the drawing, we see a grid 1 for false ceiling comprising
profiles 2 parallel to a predetermined axis, called the reference axis,
- spacers 3 perpendicular to the aforementioned reference axis 4 maintaining the sections spaced from one another and,
means 6 for fixing the load-bearing elements,
in which grid, the profiles 2 and spacers 3 are spaced at a predetermined pitch and which grid has transverse and longitudinal dimensions corresponding to multiples of the aforementioned steps.
Les profilés 2 et entretoises 3 ont généralement, vus en section, une forme en U. The profiles 2 and spacers 3 generally have, seen in section, a U-shape.
Selon une caractéristique essentielle de l'invention
- les extrémités 2A des profilés 2 de la grille sont réunies par une traverse 7 parallèle aux entretoises et présentant une aile 7A extérieure perpendiculaire au plan P de la grille dite aile verticale 7A et une aile 7B parallèle au plan de la dite grille dite aile horizontale,
- la distance D entre la traverse 7 et l'entretoise 3 la plus proche est égale au pas entre entretoises 3, et
- l'aile verticale 7A de cette traverse 7, d'une part, constitue l'un des bords de la grille et, d'autre part, présente un décrochement local par rapport aux deux plans définissant l'épaisseur de l'aile pour réaliser une zone d'accrochage avec les moyens 6 de fixation, lesquels sont constitués par au moins un tronçon 8 de profilés de section sensiblement en oméga formant une pince 8 saisissant entre ses mors 8A, 8B l'aile 7A verticale de la traverse.According to an essential characteristic of the invention
- The ends 2A of the profiles 2 of the grid are joined by a cross member 7 parallel to the spacers and having an outer wing 7A perpendicular to the plane P of the grid called the vertical wing 7A and a wing 7B parallel to the plane of the said grid called the horizontal wing ,
the distance D between the crosspiece 7 and the nearest spacer 3 is equal to the pitch between spacers 3, and
- The vertical wing 7A of this cross member 7, on the one hand, constitutes one of the edges of the grid and, on the other hand, has a local offset relative to the two planes defining the thickness of the wing for achieve a fastening zone with the fixing means 6, which are constituted by at least one section 8 of section profiles substantially in omega shape forming a clamp 8 gripping between its jaws 8A, 8B the vertical wing 7A of the crosspiece.
Le décrochement local de l'aile verticale 7A est un bossage ou un pli éventuellement roulé ou encore une rainure. The local offset of the vertical wing 7A is a boss or an optionally rolled fold or a groove.
De préférence, la pince 8 s'étend tout au long du porteur et, avantageusement, elle constitue localement le dit porteur. Preferably, the clamp 8 extends throughout the carrier and, advantageously, it locally constitutes said carrier.
Selon une caractéristique de l'invention, la largeur L de l'aile horizontale de la traverse est sensiblement égale à la moitié de la largeur Z des entretoises de sorte que lorsque deux panneaux sont disposés bord à bord, les traverses c8te à côte reconstituent visuellement une entretoise. According to a characteristic of the invention, the width L of the horizontal wing of the cross member is substantially equal to half the width Z of the spacers so that when two panels are arranged edge to edge, the cross members side by side visually reconstitute a spacer.
Cette traverse 7 a une section en L ou en U. This cross member 7 has an L or U section.
Si nécessaire, lorsque la traverse 7 a une section en U, l'aile 7A verticale qui s'engage, entre les mors 8A, 8B de la pince, sera plus longue que l'autre aile. If necessary, when the cross member 7 has a U-shaped section, the vertical wing 7A which engages between the jaws 8A, 8B of the clamp, will be longer than the other wing.
Cette disposition est nécessaire si la dimension transversale L de la traverse est inférieure à la demi-largeur de la pince. This arrangement is necessary if the transverse dimension L of the crosspiece is less than the half-width of the clamp.
Si la dimension L est supérieure à la demi-largeur de la pince 8, les deux ailes verticales de la traverse 7 pourront être d'égale longueur. If the dimension L is greater than the half-width of the clamp 8, the two vertical wings of the cross-member 7 may be of equal length.
Cela permet notamment d'utiliser un seul type de porteurs, quel que soit le pas des entretoises ou profilés choisis pour la grille et les éléments porteurs. This makes it possible in particular to use a single type of carrier, whatever the pitch of the spacers or profiles chosen for the grid and the carrier elements.
Egalement, la grille est parfaitement calée. Also, the grid is perfectly wedged.
Selon une autre caractéristique de l'invention, sur au moins l'un des côtés de la grille situe au long de l'élément porteur est associée une pièce de liaison au moins indirecte au porteur, laquelle pièce 10 présente, d'une part, une partie formant un moyen 11 d'articulation par rapport à la grille et, d'autre part, une partie 12 telle une patte reliée au porteur sans entraver la translation de la pièce 10 par rapport au porteur selon une direction sensiblement perpendiculaire au plan de la grille pour, dans un premier temps, amener la grille pourvue de cette pièce à un niveau inférieur à la face apparente du plafond puis la faire basculer à la manière d'une trappe. According to another characteristic of the invention, on at least one of the sides of the grid located along the carrier element is associated a connecting part at least indirect to the carrier, which part 10 has, on the one hand, a part forming a means 11 for articulation relative to the grid and, on the other hand, a part 12 such as a lug connected to the carrier without hindering the translation of the part 10 relative to the carrier in a direction substantially perpendicular to the plane of the grid to, at first, bring the grid provided with this part to a level lower than the visible face of the ceiling and then tilt it like a hatch.
Cette pièce 10 aura, par exemple, une forme d'épingle en U dont les extrémités 13 libres présentent des butées 14 et les branches de l'épingle sont engagées au travers d'au moins une découpe 15 que présente indirectement l'élément porteur. This part 10 will, for example, have a U-shaped pin shape, the free ends 13 of which have stops 14 and the branches of the pin are engaged through at least one cutout 15 which the supporting element indirectly presents.
Les branches de l'épingle permettent de déplacer l'axe d'articulation de la grille. The branches of the pin move the hinge pin of the grid.
De préférence, l'épingle prend appui sur un support 16 rapporté sur l'élément porteur et, par exemple, coiffant cet élement porteur. Preferably, the pin bears on a support 16 attached to the carrier element and, for example, covering this carrier element.
