Description

La présente invention concerne un faux-plafond cons­titué par une nappe tendue qui est fixée, le long de ses bords, à un cadre support lui-même fixé aux murs de la pièce dans laquelle est installé le faux-plafond.The present invention relates to a false ceiling constituted by a stretched sheet which is fixed, along its edges, to a support frame itself fixed to the walls of the room in which the false ceiling is installed.

On connaît déjà des faux-plafonds de ce type dont la nappe tendue qui est constituée par une feuille de matiè­re plastique ou une toile, comporte le long de chacun de ses côtés, une bordure en matière plastique qui présente, en section droite, l'aspect d'un crochet ou d'un harpon, ce harpon venant s'agripper sur un épaulement de profilés abou­tés constituant le cadre support fixé aux murs.False ceilings of this type are already known whose stretched sheet which is constituted by a plastic sheet or a canvas, comprises along each of its sides, a plastic border which has, in cross section, the aspect of a hook or harpoon, this harpoon gripping on a shoulder of butted sections constituting the support frame fixed to the walls.

Jusqu'à présent les faux-plafonds ont été montés avec leur nappe tendue horizontale dans sa totalité, ou bien encore avec des pans inclinés comme il est décrit par exemple dans le brevet FR-A-1 515 260. Dans le cas d'un tel faux-plafond à pans inclinés un ou plusieurs tendeurs sont disposés au-dessus de la nappe et ils sont accrochés au plafond. Toutefois ces tendeurs visent uniquement à assurer une tension satisfaisante de la nappe et ils ne permettent pas d'en modifier aisément l'aspect global pour donner un effet esthétique d'ensemble particlièrement apprécié. Par ailleurs ces tendeurs sont accrochés à des tasseaux et ba­guettes rigides assemblés, entre lesquels est serrée la nappe, et de ce fait la face inférieure de la nappe laisse apparaître ces tasseaux, ce qui nuit à l'esthétique d'ensem­ble du faux-plafond.Hitherto the false ceilings have been mounted with their horizontal stretched sheet in its entirety, or even with inclined sides as described for example in patent FR-A-1,515,260. In the case of a such as a false ceiling with inclined sides, one or more tensioners are arranged above the tablecloth and they are hung from the ceiling. However, these tensioners are only intended to ensure satisfactory tension of the ply and they do not allow the overall appearance to be easily modified to give an overall aesthetic effect which is particularly appreciated. In addition, these tensioners are hung on cleats and rigid rods assembled, between which the tablecloth is clamped, and therefore the underside of the tablecloth reveals these cleats, which harms the overall aesthetics of the false ceiling. .

La présente invention concerne des perfectionnements apportés à ce type de faux-plafond afin de permettre d'ob­tenir par des moyens très simples à mettre en oeuvre une déformation de la nappe tendue aisément adaptable en fonc­tion de l'effet esthétique recherché.The present invention relates to improvements made to this type of false ceiling in order to obtain, by very simple means, a deformation of the stretched sheet easily adaptable as a function of the desired aesthetic effect.

A cet effet ce faux plafond comportant une nappe tendue en une matière relativement élastique qui est accrochée, le long de ses bords, à un cadre support horizon­tal constitué de profilés aboutés, fixés aux murs d'une pièce, et, au-dessus de la nappe, c'est-à-dire dans l'espace compris entre cette nappe et le plafond de la pièce des moyens exerçant sur la nappe en au moins un point de cel­le-ci, un effort réglable provoquant une déformation de la nappe, est caractérisé en ce que les moyens exerçant un effort vertical réglable, vers le bas ou vers le haut, en au moins un point de la nappe comprennent un câble passant sur une poulie fixée au plafond de la pièce, dont le brin vertical agit à son extrémité inférieure sur la nappe pour exercer sur celle-ci l'effort vertical réglable, et dont 1 autre brin incliné ou brin de manoeuvre est accroché au mur au-dessus du cadre support, à ce cadre support lui-­même ou au plafond.To this end, this false ceiling comprising a sheet stretched in a relatively elastic material which is hung, along its edges, to a horizontal support frame consisting of butted sections, fixed to the walls of a room, and, above the tablecloth, that is to say in the space between this tablecloth and the ceiling of the room means exerting on the sheet at at least one point thereof, an adjustable force causing a deformation of the sheet, is characterized in that the means exerting an adjustable vertical force, downwards or upwards, in at least one point of the tablecloth include a cable passing over a pulley fixed to the ceiling of the room, whose vertical strand acts at its lower end on the tablecloth to exert on it the adjustable vertical force, and of which 1 other inclined strand or strand is hung on the wall above the support frame, on this support frame itself or on the ceiling.

L'extrémité inférieure du brin vertical du câble peut être accrochée à un objet pesant, prenant appui sur la nappe tendue et exerçant sur celle-ci de par son propre poids, une pression vers le bas engendrant une protubérance de la nappe en saillie vers le bas. L'objet pesant peut avoir toute forme appropriée suivant la forme que l'on dési­re obtenir pour la protubérance. Il peut être constitué par un bloc sphérique, elliptique ou encore prismatique de diverses sections droites, de toutes formes.The lower end of the vertical strand of the cable can be hung on a heavy object, resting on the stretched sheet and exerting on it by its own weight, a pressure downwards causing a protrusion of the sheet projecting towards the low. The heavy object can have any suitable shape according to the shape that it is desired to obtain for the protuberance. It can consist of a spherical, elliptical or even prismatic block of various cross sections, of all shapes.

Suivant une variante d'exécution de l'invention l'extrémité inférieure du brin vertical du câble est accro­chée en un point de la nappe afin de pouvoir exercer sur celle-ci une traction locale vers le haut. Cette traction provoque la formation dans la nappe d'un creux de forme sensiblement pyramidale ou conique. Notamment le brin verti­cal du câble peut être accroché à un dispositifd'éclairage, tel que spot ou caisson, fixé à la nappe au dessus de celle-ci, autour d'une ouverture ménagée dans celle-ci pour le passage du flux lumineux émis par le dispositif d éclai­rage. Dans ce cas le spot se trouve occuper le sommet de la partie en creux de forme appropriée sensiblement pyramidale ou conique ou tout autre forme en fonction de la déformation souhaitée.According to an alternative embodiment of the invention, the lower end of the vertical strand of the cable is hooked at a point on the sheet in order to be able to exert on it a local pull upwards. This traction causes the formation in the sheet of a hollow of substantially pyramidal or conical shape. In particular, the vertical strand of the cable can be hung on a lighting device, such as a spot or box, fixed to the sheet above it, around an opening made in it for the passage of the light flux emitted by the lighting device. In this case, the spot is found occupying the top of the hollow part of suitable shape substantially pyramidal or conical or any other shape depending on the desired deformation.

On décrira ci-après,à titre d'exemples non limita­tifs, diverses formes d'exécution de la présente invention, en référence au dessin annexé sur lequel:

  • La figure 1 est une vue en coupe verticale schéma­tique d'un faux-plafond suivant l'invention, utilisant un objet pesant pour déformer la nappe tendue vers le bas.
  • La figure 2 est une vue en coupe verticale schéma­tique d'une variante d'exécution du faux-plafond dans la­quelle la nappe est tirée localement vers le haut.
Various embodiments of the present invention will be described below, by way of nonlimiting examples, with reference to the appended drawing in which:
  • Figure 1 is a schematic vertical sectional view of a false ceiling according to the invention, using a heavy object to deform the sheet stretched down.
  • Figure 2 is a schematic vertical sectional view of an alternative embodiment of the false ceiling in which the sheet is drawn locally upwards.

Le faux-plafond représenté sur la figure 1 s'étend à la partie supérieure d'une pièce en dessous du plafond 1 de cette pièce, et il comprend essentiellement un cadre sup­port horizontal 2, fixé aux murs 3 de la pièce, constitué de profilés aboutés, et une nappe 4 tendue horizontalement à l'intérieur du cadre support 2. Cette nappe 4 comprend, sur chacun de ses côtés, une bordure 5 en forme de harpon, qui vient s'accrocher sur un épaulement 6 prévu sur le cadre support 2. Dans la forme d'exécution non limitative repré­sentée sur le dessin chaque profilé du cadre support 2 est constitué par une cornière et l'épaulement 6 est formé à l'extrémité de l'aile inférieure horizontale de la cornière.The false ceiling shown in Figure 1 extends to the upper part of a room below the ceiling 1 of this room, and it essentially comprises a horizontal support frame 2, fixed to the walls 3 of the room, consisting of profiles abutted, and a ply 4 stretched horizontally inside the support frame 2. This ply 4 comprises, on each of its sides, a border 5 in the form of a harpoon, which comes to hang on a shoulder 6 provided on the support frame 2. In the nonlimiting embodiment shown in the drawing, each section of the support frame 2 is constituted by an angle iron and the shoulder 6 is formed at the end of the horizontal lower wing of the angle iron.

La nappe tendue 4 est constituée en un matériau relativement élastique; par exemple elle peut être consti­tuée par une feuille de chlorure de polyvinyle.The stretched sheet 4 is made of a relatively elastic material; for example it can be constituted by a sheet of polyvinyl chloride.

Suivant l'invention, des moyens sont prévus pour déformer la nappe 4 de manière à l'écarter de sa position rigoureusement horizontale.According to the invention, means are provided for deforming the ply 4 so as to move it away from its strictly horizontal position.

Dans la forme d'exécution de l'invention représen­tée sur la figure 1 ces moyens comprennent, pour chaque point où une déformation de la nappe 4 doit être produite, une poulie 7 ou un organe de renvoi similaire fixé sous le plafond 1, à la verticale du point devant être déformé. Sur cette poulie 7 passe un câble 8 dont le brin vertical 8a est accroché, à son extrémité inférieure, à un objet pesant 9, qui a par exemple une forme sphérique. Le câble 8 comporte un autre brin incliné 8b qui part de la poulie 7 et qui s'étend jusqu'à un point 10 de fixation au mur 3, au-dessus du cadre support 2, ou bien à ce cadre support lui-même ou au plafond 1.In the embodiment of the invention shown in FIG. 1, these means comprise, for each point where a deformation of the ply 4 must be produced, a pulley 7 or a similar return member fixed under the ceiling 1, at the vertical of the point to be deformed. On this pulley 7 passes a cable 8 whose vertical strand 8a is attached, at its lower end, to a heavy object 9, which for example has a spherical shape. The cable 8 comprises another inclined strand 8b which starts from the pulley 7 and which extends to a point 10 for attachment to the wall 3, above the support frame 2, or else to this support frame itself or on the ceiling 1.

Par conséquent il est très facile pour le monteur du faux-plafond, de régler à volonté la position de l'objet pesant 9 en fonction de l'effet de déformation de la nappe 4 qu'il désire obtenir. Avant d'accrocher définitivement la nappe 4, il ajuste approximativement la position verticale de l'objet pesant 9, en tirant plus ou moins sur le brin 8b du câble 8, après quoi il attache ce câble au mur au point de fixation 10. Il monte ensuite la nappe complètement, c'est-à-dire en engageant sa bordure en forme de harpon 5 sur l'épaulement 6. Du fait de la pression exercée par l'ob­jet pesant 9, la nappe tendue 4 se déforme en s'allongeant et elle est repoussée vers le bas à la verticale de l'objet pesant 9. Elle prend ainsi une forme sensiblement pyramidale ou conique comme il est représenté sur la figure 1. Si cette forme n'est pas jugée satisfaisante, il est alors très facile de décrocher la nappe 4, sur une faible longueur, de modifier, en agissant sur le brin ou les brins de manoeu­vre 8b du câble 8, la position verticale de l'objet pesant 9, afin d'accentuer ou au contraire de réduire la déforma­tion de la nappe tendue 4, et de réaccrocher cette nappe. Sur la figure 1 est représentée, en trait mixte, une position plus basse de l'objet pesant 9, position qui en­traîne une accentuation de la déformation de la nappe.Therefore it is very easy for the installer of the false ceiling, to adjust at will the position of the heavy object 9 depending on the deformation effect of the sheet 4 which he wishes to obtain. Before permanently hanging the sheet 4, it approximately adjusts the vertical position of the weighing object 9, by pulling more or less on the strand 8b of the cable 8, after which it attaches this cable to the wall at the fixing point 10. It then mounts the ply completely, that is to say by engaging its harpoon-shaped border 5 on the shoulder 6. Due to the pressure exerted by the heavy object 9, the stretched ply 4 deforms into s' lengthening and it is pushed down vertically from the object weighing 9. It thus takes a substantially pyramidal or conical shape as shown in Figure 1. If this shape is not considered satisfactory, it is then very easy to unhook the sheet 4, over a short length, to modify, by acting on the strand or the operating strands 8b of the cable 8, the vertical position of the heavy object 9, in order to accentuate or on the contrary reduce the deformation of the stretched sheet 4, and to hang up this sheet. In Figure 1 is shown, in phantom, a lower position of the object weighing 9, a position which results in an accentuation of the deformation of the sheet.

La forme que prend la nappe 4, lorsqu'elle est ainsi déformée sous l'action de l'objet pesant 9, dépend de la forme de cet objet pesant. On peut utiliser à cet effet soit un objet sphérique comme il est représenté sur le dessin, soit un bloc ayant tout autre forme, notamment prismatique, en forme d'étoile etc...afin de provoquer une déformation particulièrement esthétique de la nappe à partir de l'en­droit où elle est en contact avec l'objet pesant 9.The shape that the web 4 takes, when it is thus deformed under the action of the heavy object 9, depends on the shape of this heavy object. One can use for this purpose either a spherical object as it is represented on the drawing, or a block having any other shape, in particular prismatic, in the shape of star etc ... in order to cause a particularly esthetic deformation of the tablecloth from from where it is in contact with the object weighing 9.

Dans la variante d'exécution de l'invention repré­sentée sur la figure 2 le brin vertical 8a du câble 8 est accroché à un dispositif d'éclairage 11 quelconque, tel qu'un spot, qui est lui-même fixé à la nappe 4, au-dessus de celle-ci, autour d'une ouverture 12 pour le passage du flux lumineux de la lampe du spot 11. Dans ce cas, du fait que le brin vertical 8a du câble 8 est accroché au spot 11, il est possible, en exerçant une traction sur le brin de manoeuvre 8b, de faire monter plus ou moins le spot 11 et de créer dans la nappe 4 un creux plus ou moins accentué suivant l'effet esthétique recherché. Là encore le réglage de la position du spot 11 s'effectue très aisément puisqu'il suf­fit de tirer plus ou moins sur le brin de manoeuvre 8b du câble 8.In the variant embodiment of the invention shown in FIG. 2, the vertical strand 8a of the cable 8 is attached to any lighting device 11, such as a spotlight, which is itself fixed to the sheet 4, above it, around an opening 12 for the passage of the light flux from the lamp of the spot 11. In this case, because the vertical strand 8a of the cable 8 is hooked to the spot 11, it is possible, by exerting traction on the operating strand 8b, to raise the spot 11 more or less and to create in the sheet 4 a more or less accentuated recess according to the desired aesthetic effect. Here again, the position of the spot 11 is adjusted very easily since it suffices to pull more or less on the operating bit 8b of the cable 8.

Le dispositif d'éclairage 11 pourrait avoir tout autre forme et il pourrait être constitué, notamment, par un caisson.The lighting device 11 could have any other shape and it could be constituted, in particular, by a box.

Suivant une variante le brin vertical 8a du câble 8 pourrait être accroché à un organe d'ancrage fixé en un point quelconque de la face supérieure de la nappe 4, sans apparaître en dessous de la nappe. Cet organe d'ancrage peut être constitué par une patte collée ou soudée sur la surface supérieure de la nappe.According to a variant, the vertical strand 8a of the cable 8 could be attached to an anchoring member fixed at any point on the upper face of the ply 4, without appearing below the ply. This anchoring member can be constituted by a tab glued or welded to the upper surface of the sheet.

D'après la description qui précède on voit que l'in­vention permet d'obtenir une déformation, réglable à volon­té, d'une nappe tendue 4 d'une seule pièce, pour lui donner un aspect esthétique recherché, et ce sans laisser voir quoi que ce soit des moyens utilisés pour le réglage de la défor­mation de la nappe qui sont logés, en totalité, entre la nappe et la plafond. De ce fait la nappe tendue et déformée présente une surface inférieure exempte d'organes de raccor­dement apparents, tels que tasseaux et baguettes.From the above description it can be seen that the invention makes it possible to obtain a deformation, adjustable at will, of a stretched sheet 4 in one piece, to give it a desired aesthetic appearance, without revealing what that it is means used for adjusting the deformation of the sheet which are housed, in full, between the sheet and the ceiling. Thereby the stretched and deformed sheet has a lower surface free of visible connecting members, such as cleats and rods.
