Description

Domaine technique : Technical area :

La présente invention concerne un dispositif de fausse paroi.The present invention relates to a false wall device.

Ce dispositif est destiné à être fixé sur une paroi telle qu'un mur ou un plafond.This device is intended to be fixed to a wall such as a wall or a ceiling.

Technique antérieure :Prior technique:

Un tel dispositif de fausse paroi comprend un panneau formé d'une nappe tendue fixée à la base d'un châssis, lequel panneau est placé dans un cadre externe, qui est muni de parois latérales et d'un fond, le dispositif comprenant également des moyens de liaison entre le châssis et le cadre externe. La nappe tendue est de préférence en un matériau polymère synthétique, par exemple du polychlorure de vinyle.Such a false wall device comprises a panel formed of a stretched web fixed to the base of a frame, which panel is placed in an external frame, which is provided with side walls and a bottom, the device also comprising connecting means between the frame and the outer frame. The stretched web is preferably made of a synthetic polymeric material, for example polyvinyl chloride.

En particulier, dans une application de type caisson lumineux, le cadre externe peut être équipé de moyens d'éclairage et la nappe peut être de type translucide. Le panneau peut encore comprendre, de manière connue, des éléments raidisseurs pour renforcer sa rigidité.In particular, in an application of the light box type, the outer frame can be equipped with lighting means and the web can be of the translucent type. The panel can also comprise, in a known manner, stiffening elements to reinforce its rigidity.

Comme mentionné précédemment, le panneau est formé d'une nappe tendue fixée à la base d'un châssis. Ce châssis, généralement parallélépipédique, est constitué de l'association d'éléments profilés qui forment chacun de ses côtés. Habituellement, la partie supérieure de ces profilés est avantageusement munie d'une rainure permettant d'accueillir des moyens de liaison du châssis au cadre externe.As mentioned previously, the panel is formed from a stretched web fixed to the base of a frame. This frame, generally parallelepiped, is made up of the association of profiled elements which form each of its sides. Usually, the upper part of these sections is advantageously provided with a groove making it possible to accommodate means for connecting the chassis to the outer frame.

La partie inférieure du profilé du châssis selon les réalisations connues, illustrées en figure 2 du présent texte et dont un exemple est donné dans la publication FR 2882588 , qui décrit un dispositif de fausse paroi selon le préambule de la revendication 1, comporte à la jonction de la base et de la partie externe du châssis un logement ouvert vers la base dudit châssis venant accueillir la bordure périphérique de la nappe tendue formant le fond du panneau. Il y a donc un espace résiduel apparent entre l'extrémité inférieure du bord extérieur du panneau et l'extrémité visible de la nappe tendue et dont l'aspect est inesthétique.The lower part of the frame profile according to known embodiments, illustrated in figure 2 of this text and an example of which is given in the publication FR 2882588 , which describes a false wall device according to the preamble of claim 1, comprises at the junction of the base and the outer part of the frame a housing open towards the base of said frame accommodating the peripheral edge of the stretched sheet forming the bottom of the panel. There is therefore an apparent residual space between the lower end of the outer edge of the panel and the visible end of the stretched web, the appearance of which is unsightly.

Résumé de l'inventionSummary of the invention

La présente invention vise donc à remédier à cet inconvénient en proposant des dispositifs de panneau selon l'une des revendications 1 à 3.The present invention therefore aims to remedy this drawback by proposing panel devices according to one of claims 1 to 3.

Le logement de réception débouche sur la partie externe et est intégré dans l'épaisseur de l'élément profilé, entre la partie interne et la partie externe. Ce logement, qui est situé entre la partie externe et la partie interne, n'est donc pas en saillie de la partie externe du profilé.The receiving housing opens onto the external part and is integrated into the thickness of the profiled element, between the internal part and the external part. This accommodation, which is located between the external part and the internal part, is therefore not projecting from the external part of the profile.

Le logement de réception présente de fait une orientation sécante avec la partie externe du profilé, sur laquelle il débouche.The receiving housing has in fact an orientation intersecting with the external part of the profile, on which it opens.

Selon une variante préférée, le logement présente une section droite globalement rectangulaire, ouverte sur le côté débouchant, et comporte un épaulement au bord de ladite ouverture. L'extrémité libre de la bordure périphérique de la nappe vient en appui sur ledit épaulement.According to a preferred variant, the housing has a generally rectangular cross section, open on the emerging side, and comprises a shoulder at the edge of said opening. The free end of the peripheral edge of the sheet comes to bear on said shoulder.

On comprend bien que grâce à cet agencement spécifique des profilés, dans lequel la bordure périphérique de la nappe vient s'enclencher dans la partie externe des profilés, la nappe va ainsi recouvrir l'ensemble de la face inférieure et également une portion de la partie externe dudit châssis, l'espace résiduel présent dans les profilés selon l'art antérieur connu étant ainsi supprimé.It will be understood that thanks to this specific arrangement of the profiles, in which the peripheral edge of the sheet engages in the external part of the profiles, the sheet will thus cover the whole of the lower face and also a portion of the part. external of said frame, the residual space present in the profiles according to the known prior art thus being eliminated.

Description détaillée de l'inventionDetailed description of the invention

On a représenté à la figure 1 un dispositif 1 de fausse paroi selon l'invention, dans une configuration d'utilisation de type caisson lumineux.We have represented at the figure 1 a false wall device 1 according to the invention, in a configuration of use of the light box type.

Ce dispositif 1 comporte un panneau 3 logé dans un cadre externe 5.This device 1 comprises a panel 3 housed in an external frame 5.

Le panneau 3 est formé d'une nappe tendue 7 fixée à la base d'un châssis 9. Ce châssis 9, qui est ici de forme parallélépipédique, est constitué de l'association d'éléments profilés 11 qui forment chacun de ses côtés, ici au nombre de quatre, et qui se terminent par des coupes d'onglet, ici à 90°, reliés par des équerres non représentées sur le dessin. En outre, le châssis 9 est pourvu d'un élément raidisseur 12 reliant deux éléments profilés 11 opposés du châssis 9.The panel 3 is formed of a stretched sheet 7 fixed to the base of a frame 9. This frame 9, which here is of parallelepiped shape, consists of the association of profiled elements 11 which form each of its sides, here four in number, and which end in miter cuts, here at 90 °, connected by brackets not shown in the drawing. In addition, the frame 9 is provided with a stiffening element 12 connecting two opposed profiled elements 11 of the frame 9.

Le cadre externe 5 comprend quatre parois latérales 13 définissant un quadrilatère sur lequel est monté un fond 15. Sur ce fond 15 sont disposés des moyens d'éclairage constitués par exemple de tubes à décharge 16 parallèles.The outer frame 5 comprises four side walls 13 defining a quadrilateral on which is mounted a base 15. On this base 15 are arranged lighting means consisting for example of discharge tubes 16 parallel.

Dans l'exemple d'utilisation représenté, le cadre externe 5 forme une enveloppe destinée à être fixé à une paroi telle qu'un mur ou un plafond. Toutefois, le cadre externe 5, au sens de la présente invention, pourra également être constitué par une niche aménagée dans une paroi ou bien par un poteau en H ou en U équipé de deux parois latérales transversales supplémentaires pour former ainsi le réceptacle du panneau 3.In the example of use shown, the outer frame 5 forms an envelope intended to be fixed to a wall such as a wall or a ceiling. However, the outer frame 5, within the meaning of the present invention, may also be constituted by a recess arranged in a wall or else by an H or U-shaped post fitted with two additional transverse side walls to form thus the receptacle of the panel 3.

Pour permettre les opérations de maintenance, tant de la face interne de la nappe tendue 7 (nettoyage), que celle des moyens d'éclairage (nettoyage et remplacement tubes à décharge 16), la liaison entre le panneau 3 et le cadre externe 5 ou bien la configuration du cadre externe 5, est telle qu'elle permet un accès à l'espace compris entre la face arrière du panneau 3 et le cadre externe 5.To allow maintenance operations, both on the internal face of the stretched sheet 7 (cleaning), and that of the lighting means (cleaning and replacement of discharge tubes 16), the connection between the panel 3 and the external frame 5 or indeed the configuration of the outer frame 5 is such that it allows access to the space between the rear face of the panel 3 and the outer frame 5.

Par exemple, le dispositif 1 de fausse paroi pourra comporter un ensemble charnière reliant le panneau 3 et le cadre externe 5 de manière à permettre un basculement du panneau 3 par rapport au cadre externe 5. Des exemples d'articulation du panneau 3 par rapport à son cadre externe 5 sont connus notamment du document FR 2 882 588 et FR 2 911 619 , dans le cadre d'une application de type caisson lumineux.For example, the false wall device 1 may include a hinge assembly connecting the panel 3 and the outer frame 5 so as to allow the panel 3 to tilt relative to the outer frame 5. Examples of articulation of the panel 3 relative to its external frame 5 are known in particular from the document FR 2 882 588 and FR 2 911 619 , in the context of a light box type application.

Une autre possibilité est de prévoir qu'au moins une paroi latérale 11 et/ou le fond 15 du cadre externe 5 puisse être articulé ou mobile, permettant ainsi un accès latéral et/ou arrière à l'espace interne entre le panneau 3 et le cadre externe 5 pour pouvoir réaliser les opérations de maintenance mentionnées.Another possibility is to provide that at least one side wall 11 and / or the bottom 15 of the outer frame 5 can be articulated or movable, thus allowing lateral and / or rear access to the internal space between the panel 3 and the external frame 5 to be able to carry out the maintenance operations mentioned.

Enfin, on pourra prévoir des moyens de liaison amovibles entre le panneau 3 et le cadre externe 5, du type attaches ou fixations rapides, telles que par exemple des grenouillères ou autres verrous quart de tour.Finally, removable connecting means can be provided between the panel 3 and the outer frame 5, of the type of fasteners or fasteners, such as, for example, latches or other quarter-turn locks.

(technique antérieure)(prior art)

On a représenté à la figure 2 un mode de réalisation selon l'art antérieur connu des éléments profilés 11 formant le châssis 9 du panneau 3 à la base duquel est fixée la nappe tendue 7.We have represented at the figure 2 an embodiment according to the known prior art of profiled elements 11 forming the frame 9 of the panel 3 to the base of which the stretched sheet 7 is fixed.

La partie inférieure du profilé 11 se termine par deux ailes parallèles 17,18 s'étendant vers la base du châssis. Ces deux ailes 17,18 définissent un logement ouvert sur la base du châssis. L'aile externe 17, qui est dans le prolongement de la partie externe du profilé 11, est pourvue sur sa face intérieure d'une butée 19 transversale destinée à recevoir en simple appui une extrémité d'une bordure périphérique 20 de la nappe 7 tendue formant le fond du panneau 3.The lower part of the profile 11 ends with two parallel wings 17,18 extending towards the base of the frame. These two wings 17,18 define an open housing on the base of the frame. The outer flange 17, which is in the extension of the outer part of the profile 11, is provided on its inner face with a transverse stop 19 intended to receive in simple support one end of a peripheral edge 20 of the stretched sheet 7. forming the bottom of the panel 3.

Comme cela ressort de la figure 2, un espace e subsiste entre la partie externe desdits profilés et l'extrémité visible de la nappe 7. Cet espace résiduel permet le montage et surtout le démontage par insertion d'une spatule à l'intérieur de la bordure périphérique de la nappe. Toutefois, cet espace résiduel entre la nappe et le bord externe du châssis est visuellement gênant car il constitue un joint creux donnant une impression très inesthétique.As emerges from the figure 2 , a space e remains between the external part of said sections and the visible end of the web 7. This residual space allows assembly and especially disassembly by inserting a spatula inside the peripheral edge of the web. However, this residual space between the web and the outer edge of the frame is visually annoying because it constitutes a hollow joint giving a very unsightly impression.

De plus, on relève que dans la structure des profilés 11 selon l'art antérieur, la partie interne oblique 21 du profilé se termine à une certaine distance du bord externe du châssis en projection horizontale sur la nappe. Lorsque le dispositif 1 est muni de moyens d'éclairage sur le fond 15 du cadre externe 5, un masque d'ombre projetée sur la toile 7 va être visible à la périphérie de la base du châssis, masque dont la largeur va globalement correspondre à l'addition de la largeur de l'espace résiduel e et la distance projetée entre l'extrémité basale de la partie interne 21 oblique et l'aile 18. Ce masque d'ombre périphérique est visuellement gênant.In addition, it is noted that in the structure of the profiles 11 according to the prior art, the oblique internal part 21 of the profile ends at a certain distance from the outer edge of the frame in horizontal projection on the web. When the device 1 is provided with lighting means on the bottom 15 of the outer frame 5, a shadow mask projected on the canvas 7 will be visible at the periphery of the base of the frame, the width of which will generally correspond to the addition of the width of the residual space e and the distance projected between the basal end of the oblique internal part 21 and the wing 18. This peripheral shadow mask is visually disturbing.

(meilleur mode de réalisation de l'invention)(best embodiment of the invention)

En référence à la figure 3, on décrira maintenant un premier exemple d'exécution d'un profilé 11 selon l'invention. Ce profilé 11 présente une forme de triangle rectangle avec une pointe orientée vers la base du châssis et dont l'hypoténuse constitue la partie interne dudit châssis. Le profilé 11 comporte ainsi une partie interne 21 en oblique, une partie supérieure 22 et une partie externe 23, orientée perpendiculairement à la partie supérieure 22. Lorsque le panneau est placé dans le cadre externe 5, la partie supérieure 22 de chaque profilé 11 est en regard du fond 15 dudit cadre externe 5 tandis que la partie externe 23 est disposée en regard de la paroi latérale 13 respective du cadre externe 5.With reference to the figure 3 , we will now describe a first embodiment of a section 11 according to the invention. This profile 11 has a triangle shape rectangle with a point oriented towards the base of the frame and the hypotenuse of which constitutes the internal part of said frame. The section 11 thus comprises an internal part 21 obliquely, an upper part 22 and an external part 23, oriented perpendicular to the upper part 22. When the panel is placed in the external frame 5, the upper part 22 of each section 11 is facing the bottom 15 of said outer frame 5 while the outer part 23 is disposed facing the respective side wall 13 of the outer frame 5.

La partie interne 21 en oblique est munie à son extrémité basale d'une aile d'appui 24 de la nappe 7, venant au droit de la partie externe 23. On notera qu'ainsi, l'empreinte du châssis 3 sur la toile 7 est avantageusement réduite à l'épaisseur de l'aile d'appui 24, se réduisant donc à une simple ligne et supprimant toute ombre portée visuellement gênante lorsque le dispositif 1 est muni de moyens d'éclairage sur le fond 15 du cadre externe 5.The internal part 21 obliquely is provided at its basal end with a support wing 24 of the web 7, coming to the right of the external part 23. It will be noted that thus, the imprint of the frame 3 on the fabric 7 is advantageously reduced to the thickness of the support wing 24, therefore reducing to a single line and eliminating any visually disturbing cast shadow when the device 1 is provided with lighting means on the bottom 15 of the outer frame 5.

Selon une caractéristique essentielle de l'invention, la partie externe 23 du profilé 11 est munie d'un logement 25 destiné à recevoir la bordure périphérique 20 de la nappe 7 tendue. Ce logement 25 comporte un épaulement 26 sur lequel l'extrémité libre de la bordure périphérique 20 vient en appui, permettant ainsi le verrouillage et l'enclenchement de la nappe 7 dans ce logement 25. Ce logement de réception 25 de la bordure périphérique 20 de la nappe 7 tendue est situé à proximité de l'extrémité basale dudit profilé 11.According to an essential characteristic of the invention, the external part 23 of the section 11 is provided with a housing 25 intended to receive the peripheral edge 20 of the stretched sheet 7. This housing 25 comprises a shoulder 26 on which the free end of the peripheral edge 20 bears, thus allowing the locking and engagement of the web 7 in this housing 25. This receiving housing 25 of the peripheral edge 20 of the stretched sheet 7 is located near the basal end of said section 11.

Le logement 25 a une section droite globalement rectangulaire ouverte sur un coté, débouchant sur la partie externe 23. L'épaulement 26 est placé au bord de cette ouverture. En outre, dans la variante d'exécution représentée, le logement 25 s'étend perpendiculairement à la partie externe 23, en direction de la partie interne 21.The housing 25 has a generally rectangular cross section open on one side, opening onto the external part 23. The shoulder 26 is placed at the edge of this opening. In addition, in the embodiment shown, the housing 25 extends perpendicularly to the external part 23, in the direction of the internal part 21.

Selon une autre caractéristique de l'invention, le logement 25 est situé à proximité de l'extrémité basale du profilé 11.According to another characteristic of the invention, the housing 25 is located near the basal end of the profile 11.

La partie externe 23 comporte également deux logements secondaires 27 pouvant accueillir des joints brosses ou des galets de roulement afin d'améliorer le coulissement du panneau par rapport au cadre externe, si le dispositif est équipé d'une ensemble charnière.The outer part 23 also comprises two secondary housings 27 which can accommodate brush seals or rolling rollers in order to improve the sliding of the panel relative to the outer frame, if the device is equipped with a hinge assembly.

La partie supérieure 22 est munie d'un logement longitudinal 28 destiné à recevoir des éléments de liaison du châssis 9 au cadre externe 5.The upper part 22 is provided with a longitudinal housing 28 intended to receive elements for connecting the frame 9 to the outer frame 5.

En référence à la figure 4, on décrira une seconde variante d'exécution du profilé constitutif du cadre du panneau. Cette seconde variante présente une structure simplifiée dans laquelle la partie externe 23 du profilé 11 est creuse.With reference to the figure 4 , a second variant embodiment of the section constituting the frame of the panel will be described. This second variant has a simplified structure in which the external part 23 of the profile 11 is hollow.

Le logement 25 pour l'enclenchement de la bordure périphérique 20 de la nappe 7 tendue est situé immédiatement sous le logement longitudinal 28 de la partie supérieure 22. Le logement 25 est donc situé à proximité de la partie supérieure 22 du profilé 11.The housing 25 for engaging the peripheral edge 20 of the stretched sheet 7 is located immediately under the longitudinal housing 28 of the upper part 22. The housing 25 is therefore located near the upper part 22 of the section 11.

La structure de cette variante est donc basée autour d'une âme verticale centrale 30. Son extrémité supérieure est prolongée par le logement longitudinal 28 de la partie supérieure 22. A proximité de cette dernière, sont issues perpendiculairement à l'âme 30 deux ailes 31, 32, une aile interne 31 et une aile externe 32. Le logement 25 pour l'enclenchement de la bordure périphérique 20 de la nappe 7 tendue est compris entre le bord inférieur du logement longitudinal 28, l'âme 30 et l'aile externe 32.The structure of this variant is therefore based around a central vertical core 30. Its upper end is extended by the longitudinal housing 28 of the upper part 22. Close to the latter, two wings 31 exit perpendicularly to the core 30. , 32, an internal flange 31 and an outer flange 32. The housing 25 for engaging the peripheral edge 20 of the stretched web 7 is between the lower edge of the longitudinal housing 28, the core 30 and the outer flange 32.

Le logement 25 présente une section droite globalement rectangulaire ouverte sur un coté, débouchant sur la partie externe 23, avec un épaulement 26 placé au bord de cette ouverture. En outre, dans la variante d'exécution représentée le logement 25 s'étend perpendiculairement à la partie externe 23, en direction de la partie interne 21.The housing 25 has a generally rectangular cross section open on one side, opening onto the external part 23, with a shoulder 26 placed at the edge of this opening. In addition, in the embodiment shown, the housing 25 extends perpendicularly to the external part 23, in the direction of the internal part 21.

L'extrémité basale de l'âme verticale 30 est au contact de la partie interne 21 oblique du profilé 11. Cette dernière est prolongée de façon coplanaire par une aile d'appui basale 33 de la nappe 7. Les extrémités libres de l'aile d'appui basale 33 de la nappe et de l'aile externe 32 sont situées dans un même plan. Là encore, on notera que l'empreinte du châssis 3 sur la toile 7 est avantageusement réduite à l'épaisseur de l'aile d'appui 24, se réduisant donc à une simple ligne et supprimant toute ombre portée gênante lorsque le dispositif 1 est muni de moyens d'éclairage sur le fond 15 du cadre externe 5.The basal end of the vertical core 30 is in contact with the oblique internal part 21 of the section 11. The latter is extended coplanarly by a basal support wing 33 of the web 7. The free ends of the wing basal support 33 of the web and of the outer wing 32 are located in the same plane. Here again, it will be noted that the imprint of the frame 3 on the canvas 7 is advantageously reduced to the thickness of the support wing 24, therefore being reduced to a single line and eliminating any annoying cast shadow when the device 1 is provided with lighting means on the bottom 15 of the outer frame 5.

Application industrielleIndustrial application
