Description

SYSTEME DE FIXATION DE FAUSSES PAROIS NON PAl^AITEMENT TENDUES FIXING SYSTEM FOR FALSE WALLS NOT CLEARLY TIGHTENED
La présente invention concerne le domaine des fausses parois telles que les faux-plafonds et les faux-murs et en particulier ceux constitués par une nappe souple non parfaitement tendue accrochée le long de ses bords à un support fixé aux murs ou au plafond d'une pièce d'un bâtiment.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 not perfectly stretched hung along its edges to a support fixed to the walls or ceiling of a piece of a building.
On connaît déjà des faux-plafonds tendus qui comprennent d' une part un cadre fixé aux murs ou au plafond d'une pièce, ce cadre étant formé par une lisse extérieure constituée elle-même de profilés aboutés, et d'autre part, une nappe souple tendue à l'intérieur de ce cadre, cette nappe souple étant constituée par une feuille de matière plastique ou une toile. La nappe souple est maintenue tendue du fait de l'accrochage, sur la lisse, d'une bordure solidaire de la nappe formant un harpon, cette bordure présentant en section droite la forme d'un crochet venant s'agripper sur un épaulement de la lisse.Stretched 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 consisting of abutting profiles, and on the other hand, a flexible ply stretched inside this frame, this flexible ply being constituted by a sheet of plastic or a fabric. The flexible sheet is held taut because of the attachment, on the rail, of a border integral with the web forming a harpoon, this border having in cross section the shape of a hook which grips on a shoulder of the smooth.
Ces fausses parois connues reposent sur le principe d'une mise sous tension de la nappe souple sur le cadre, de manière parfaitement plane, horizontalement ou verticalement selon qu'il s'agisse d'un faux-plafond ou d'un faux-mur et sont donc adéquates pour recouvrir des murs ou plafonds parfaitement plans.These known false walls are based on the principle of a power of the flexible sheet on the frame, perfectly flat, horizontally or vertically depending on whether it is a false ceiling or a false wall and are therefore suitable for covering perfectly flat walls or ceilings.
Dans le cas de surfaces à recouvrir qui ne sont pas planes, par exemple ondulées ou courbes, comme par exemple un plafond en voûte, il n'est pas possible de tendre parfaitement la nappe si l'on veut éviter un aspect en lignes brisées de la fausse paroi. Il est donc nécessaire de pouvoir fixer la nappe sur des lisses de manière à ce qu'elle soit non parfaitement tendue tout en étant maintenue dans lesdites lisses.In the case of surfaces to be covered that are not flat, for example corrugated or curved, such as a vaulted ceiling, it is not possible to stretch the sheet perfectly if one wants to avoid a broken lines appearance of the false wall. It is therefore necessary to be able to fix the sheet on smooth so that it is not perfectly stretched while being held in said rails.
Or le harpon classiquement employé, prévu pour permettre un démontage éventuel de la fausse paroi puis son repositionnement, se désengage systématiquement de son contact sur l'épaulement de la lisse lorsque la nappe est détendue, même légèrement. Il ne convient donc pas à l'utilisation recherchée.However harpoon classically used, intended to allow possible disassembly of the false wall and its repositioning, systematically disengages from its contact on the shoulder of the rail when the web is relaxed, even slightly. It is therefore not suitable for the intended use.
La présente invention a donc pour objet de présenter un nouveau système de fixation de fausses parois constituées d'une nappe souple non parfaitement tendue et accrochées par ses bordures à un cadre fixé aux murs ou au plafond d'une pièce d'un bâtiment, ledit cadre étant constitué par des lisses présentant un épaulement sur lequel la bordure vient en appui, ladite bordure ou harpon ayant une section en forme de crochet et comportant une aile par laquelle ledit harpon est relié à la nappe et un bourrelet .The object of the present invention is therefore to present a new system for fixing false walls consisting of a flexible sheet not perfectly stretched and hung by its borders to a frame fixed to the walls or the ceiling of a part of a building, said frame being constituted by smooth having a shoulder on which the edge bears, said edge or harpoon having a hook-shaped section and having a wing by which said harpoon is connected to the web and a bead.
A cet égard, le système selon l'invention est remarquable en ce que la bordure solidaire de la nappe, ou harpon, est réalisée dans une matière semi-souple et présente un degré de souplesse tel que les deux branches s'écartent au moins de 45° l'une de l'autre après que ladite bordure ait été insérée dans la lisse, de manière à ce que la portion de la face interne du bourrelet, c'est-à- dire la face en regard de l'aile, qui est située vers l'extrémité libre dudit bourrelet soit au contact de l'épaulement et assure ainsi un maintien par friction du harpon dans la lisse. D'autres avantages et caractéristiques ressortiront mieux de la description qui va suivre d'une variante d'exécution du système de fixation selon l'invention en référence aux figures annexées sur lesquelles :In this respect, the system according to the invention is remarkable in that the integral edge of the web, or harpoon, is made of a semi-flexible material and has a degree of flexibility such that the two branches deviate at least from 45 ° from each other after said edge has been inserted into the rail, so that the portion of the inner face of the bead, that is to say the face facing the wing, which is located towards the free end of said bead is in contact with the shoulder and thus ensures a frictional hold of the harpoon in the smooth. Other advantages and features will become more apparent from the following description of an alternative embodiment of the fastening system according to the invention with reference to the appended figures in which:
- la figure 1 est une vue en coupe verticale partielle d'un faux-plafond constitué par une nappe tendue, et comportant une lisse fixée à la partie supérieure d'un mur d'une pièce selon l'art antérieur connu ;- Figure 1 is a partial vertical sectional view of a false ceiling consisting of a stretched web, and having a rail attached to the upper part of a wall of a room according to the known prior art;
- la figure 2 est une vue en coupe verticale partielle, à la même échelle et selon le même angle de vue que la figure 1, d'un faux-plafond constitué d'une nappe non parfaitement tendue comportant une lisse identique à celle représentée à la figure 1 et une variante d'exécution du système de fixation selon l'invention. La figure 1 représente la partie extrême d'un faux- plafond suivant l'art antérieur, qui est constitué par une nappe 1 souple tendue horizontalement en-dessous du plafond 2 d'une pièce. Cette nappe 1 est fixée le long de ses bords à un support constitué par une lisse horizontale 3, elle-même fixée à la partie supérieure d'un mur 4 de la pièce par des moyens appropriés, non représentés, tels que des vis. Cette lisse 3 comprend une aile 'verticale externe 5 qui s'étend parallèlement au mur 4 et à proximité immédiate de celui-ci. De cette aile verticale externe 5 est issu, à peu près à mi-hauteur, une âme horizontale supérieure 6 s' étendant sur une faible distance, par exemple de l'ordre de 7 mm, vers l'intérieur de la pièce. Cette âme 6 se prolonge, à son extrémité, par une aile verticale interne 7 s' étendant vers le bas un peu plus bas que l'aile externe 5 proche du mur 4, c'est-à-dire que l'aile interne 7 est un peu plus haute que l'aile externe 5 de ladite lisse. Cette aile externe 5 présente, à son extrémité inférieure, un épaulement 8 s' étendant horizontalement vers l'intérieur de la pièce, sur une faible distance qui est par exemple de 3 mm. Cet épaulement à l'équerre 8 présente avantageusement une extrémité arrondie.FIG. 2 is a partial vertical sectional view, at the same scale and at the same angle of view that Figure 1, a false ceiling consists of a not perfectly stretched sheet having a smooth identical to that shown in Figure 1 and an alternative embodiment of the fastening system according to the invention. Figure 1 shows the end portion of a false ceiling according to the prior art, which is constituted by a flexible sheet 1 stretched horizontally below the ceiling 2 of a room. This sheet 1 is fixed along its edges to a support consisting of a horizontal rail 3, itself attached to the upper part of a wall 4 of the part by appropriate means, not shown, such as screws. This smooth 3 comprises an outer vertical wing 5 which extends parallel to the wall 4 and in the immediate vicinity thereof. This outer vertical wing 5 is issued, at about halfway up, an upper horizontal web 6 extending over a small distance, for example of the order of 7 mm, towards the interior of the room. This core 6 is extended, at its end, by an internal vertical wing 7 extending downward a little lower than the outer wing 5 near the wall 4, that is to say that the inner wing 7 is a little higher than the outer wing 5 of said smooth. This outer flange 5 has, at its lower end, a shoulder 8 extending horizontally towards the interior of the part, over a short distance which is for example 3 mm. This shoulder to the square 8 advantageously has a rounded end.
La partie inférieure de l'aile verticale externe 5, l'âme horizontale supérieure 6 et l'aile verticale 7 constituent un évidement 9 ouvert vers le bas et dans lequel est engagé un harpon 10 constituant la bordure de la nappe souple tendue 1.The lower part of the outer vertical wing 5, the upper horizontal web 6 and the vertical wing 7 constitute a recess 9 open towards the bottom and in which is engaged a harpoon 10 forming the edge of the stretched flexible sheet 1.
Ce harpon 10 présente en section droite une forme de crochet s' étendant vers le mur 4 et ouvert vers le bas. Il comprend une branche interne 1Oa1, ou aile, par laquelle il est relié à la nappe 1, et une branche externe 10b en forme de bourrelet à l'extrémité arrondie, qui est recourbée vers le bas. Le harpon 10 prend appui, lorsque la nappe 1 est tendue, sur l'épaulement 8 par l'extrémité inférieure de sa branche externe 10b qui s'étend vers le bas.This harpoon 10 has in cross section a form of hook extending towards the wall 4 and open downwards. he comprises an inner limb 10a 1 , or wing, by which it is connected to the ply 1, and an outer branch 10b in the form of a bead at the rounded end, which is curved downwards. The harpoon 10 is supported, when the sheet 1 is stretched, on the shoulder 8 by the lower end of its outer branch 10b which extends downwards.
Ce harpon 10 est simplement en appui sur l'épaulement inférieur horizontal 8 par son bourrelet 10b et par conséquent, sa mise en position d'accrochage est grandement facilité. En effet, lors du montage de la toile tendue, il suffit de repousser le harpon 10 vers le haut dans l'évidement 9, au moyen d'un outil approprié, telle qu'une spatule engagée dans ce harpon 10, pour le faire passer entre l'épaulement 8 et l'aile verticale 7 et l'amener au- dessus de l'épaulement 8. Lorsque l'on relâche le harpon 10, celui-ci vient alors de lui-même en appui sur l'épaulement 8 en assurant un maintien parfait de la nappe tendue 1, grâce à l'effet ressort entre les deux branches du harpon procuré par la matière dans laquelle celui-ci est fabriqué et la traction exercée sur la branche interne 10a par la nappe 1. L'effet ressort mentionné consiste en un rapprochement des deux branches. L'angle formé entre les deux branches du harpon en position est inférieur à 15°.This harpoon 10 is simply supported on the lower horizontal shoulder 8 by its bead 10b and therefore, its setting in hooking position is greatly facilitated. Indeed, during the assembly of the stretched fabric, it suffices to push the harpoon 10 upwards in the recess 9, by means of a suitable tool, such as a spatula engaged in this harpoon 10, to make it pass between the shoulder 8 and the vertical flange 7 and bring it above the shoulder 8. When the harpoon 10 is released, it then comes to rest on the shoulder 8 ensuring a perfect maintenance of the stretched web 1, thanks to the spring effect between the two branches of the harpoon provided by the material in which it is manufactured and the traction exerted on the inner branch 10a by the web 1. The effect mentioned spring consists of a rapprochement of the two branches. The angle formed between the two branches of the harpoon in position is less than 15 °.
En référence à la figure 2, on notera que les lisses 3 des deux systèmes de fixation sont parfaitement identiques, seul le harpon 10' permettant d'accrocher la nappe 1 auxdites lisses 3 diffère.Referring to Figure 2, it will be noted that the rails 3 of the two fastening systems are perfectly identical, only the harpoon 10 'for hanging the sheet 1 to said smooth 3 differs.
Tout d'abord, on relèvera que les dimensions de la variante d'exécution représentée du harpon 10' selon l'invention sont, concernant la longueur de son aile 10' a, ou branche interne, et de son bourrelet 10'b, ou branche externe, inférieures à celles du harpon 10 conventionnellement utilisé et représenté sur la figure 1 : les figures 1 et 2 étant à la même échelle, la branche externe de la variante représentée du harpon 10' selon l'invention, également qualifiée de mini-harpon, présente quasiment la même longueur que la branche interne du harpon 10 de l'art antérieur. Il va bien entendu de soi que les dimensions du harpon 10' ne sont pas limitatives de l'invention et que dans une autre variante d'exécution du système de fixation selon l'invention, non représentée, le harpon 10' pourra présenter des dimensions similaires à celle du harpon conventionnel 10. Selon une caractéristique essentielle de l'invention, la bordure, ou harpon 10' , est réalisée dans une matière semi-souple et présente un degré de souplesse tel que les deux branches 10' a_ et 10'b s'écartent au moins de 45° l'une de l'autre après que ladite bordure ait été insérée dans la lisse 3, de manière à ce que la portion de la face interne du bourrelet 10'b, c'est-à-dire la face en regard de l'aile 10' a, qui est située vers l'extrémité libre dudit bourrelet soit au contact de l'épaulement 8 et assure ainsi un maintien par friction du harpon 10' dans la lisse 3. Le harpon 10' objet de la présente invention est avantageusement réalisé dans une matière plastique extrudée semi-souple, similaire à celle du harpon 10 constitutif de l'art antérieur mais procurant un degré de souplesse supérieur de sorte que les branches puissent s'écarter l'une de l'autre.First of all, it will be noted that the dimensions of the represented variant of the harpoon 10 'according to the invention are, concerning the length of its wing 10' a, or internal branch, and its bead 10'b, or external branch, less than those of the harpoon 10 conventionally used and shown in FIG. 1: FIGS. 1 and 2 being at the same scale, the branch external of the represented variant of the harpoon 10 'according to the invention, also called mini-harpoon, has almost the same length as the inner branch of the harpoon 10 of the prior art. It goes without saying of course that the dimensions of the harpoon 10 'are not limiting of the invention and that in another alternative embodiment of the fastening system according to the invention, not shown, the harpoon 10' may have dimensions similar to that of the conventional harpoon 10. According to an essential characteristic of the invention, the border, or harpoon 10 ', is made of a semi-flexible material and has a degree of flexibility such that the two branches 10' a and 10 ' b deviate at least 45 ° from each other after said edge has been inserted into the rail 3, so that the portion of the inner face of the bead 10'b, that is to say the face facing the wing 10 'a, which is located towards the free end of said bead is in contact with the shoulder 8 and thus provides a frictional hold of the harpoon 10' in the smooth 3. The harpoon 10 'object of the present invention is advantageously made of a plastic material extruded semi-flexible, similar to that of the spear 10 constituting the prior art but providing a higher degree of flexibility so that the branches can deviate from one another.
Ainsi, lors de la mise en place du harpon 10' dans le logement 9 de la lisse 3, le poids exercé par la nappe souple 1 sur le harpon va écarter les deux branches de celui-ci. L'angle d' écartement des deux branches est d'au moins 45°. De préférence, il sera compris entre 70° et 130°, préférentiellement proche des 90°. Grâce à cet écartement des branches, la portion de la face interne du bourrelet 10'b située vers son extrémité libre vient au contact de la surface de l'épaulement 8. La force de friction exercée est suffisante pour permettre le maintien en place du harpon 10' sans possibilité de dégagement inopportun de celui-ci.Thus, when placing the harpoon 10 'in the housing 9 of the rail 3, the weight exerted by the flexible web 1 on the harpoon will move the two branches thereof. The angle of separation of the two branches is at least 45 °. Preferably, it will be between 70 ° and 130 °, preferably close to 90 °. Thanks to this separation of the branches, the portion of the inner face of the bead 10'b located towards its free end comes into contact with the surface of the shoulder 8. The friction force exerted is sufficient to allow the holding in place of the harpoon 10 'without the possibility of improper release of it.
Selon une caractéristique optionnelle de l'invention, l'extrémité inférieure du bourrelet 10'b du harpon 10' pourra être avantageusement biseautée de façon à présenter une section plane. L'extrémité du bourrelet 10' b étant biseautée, celui-ci présente donc deux surfaces franches donc l'une est au contact de l'épaulement 8. On comprend bien que les surfaces en contact étant planes, le maintien procuré par les forces de friction n'en sera que meilleur.According to an optional feature of the invention, the lower end of the bead 10 'of the harpoon 10' may be advantageously bevelled so as to have a flat section. The end of the bead 10 'b being beveled, it has two surfaces so blunt one is in contact with the shoulder 8. It is understood that the contacting surfaces being flat, the maintenance provided by the forces of friction will only be better.
Enfin, la présente invention s'applique plus particulièrement aux faux-plafonds non plans, mais il est bien évident que les exemples que l'on vient de donner ne sont qu'une illustration particulière en aucun cas limitative quant aux domaines d'application de l'invention. Finally, the present invention applies more particularly to non-flat false ceilings, but it is obvious that the examples just given are only a particular illustration in no way limiting as to the fields of application of the invention.
