On peut se reporter également aux demandes de brevet en France issues de la demanderesse : 2 811 693 , 2 736 615 , 2 756 600 , 2 727 711 , 2 712 325 , 2 699 613 , 2 695 670 , 2 692 302 , 2 658 849 .We can also refer to the patent applications in France from the plaintiff: 2,811,693 , 2,736,615 , 2,756,600 , 2,727,711 , 2,712,325 , 2,699,613 , 2,695,670 , 2,692,302 , 2,658,849 .

Les faux plafonds tendus conventionnels comprennent :

  • d'une part, un cadre fixé sur la partie supérieure des murs d'un local, ce cadre étant formé par des lisses, c'est à dire des profilés aboutés ;
  • d'autre part, une nappe tendue à l'intérieur de ce cadre.
Conventional taut ceilings include:
  • on the one hand, a frame fixed on the upper part of the walls of a room, this frame being formed by smooth, ie butted profiles;
  • on the other hand, a sheet stretched inside this frame.

Cette disposition assure un caractère démontable au faux plafond tendu, permettant une intervention dans le plénum.This arrangement ensures a removable character to false ceiling stretched, allowing intervention in the plenum.

Le maintien de la nappe par rapport au cadre de lisses est obtenu par différentes voies (accrochage, arc-boutement, encliquetage, serrage, pincement), illustrées par exemple dans les demandes de brevet en France publiées sous les numéros 1 303 930 , 1 475 446 , 2 002 261 , 2 734 296 , 2 699 211 , 2 537 112 , 2 597 906 , 2 619 531 , 2 630 476 , 2 811 693 .The maintenance of the ply relative to the heald frame is obtained by different ways (hooking, buttressing, snapping, clamping, pinching), illustrated for example in the patent applications in France published under the numbers 1 303 930 , 1,475,446 , 2,002,261 , 2,734,296 , 2,699,211 , 2,537,112 , 2,597,906 , 2,619,531 , 2,630,476 , 2,811,693 .

On connaît par ailleurs, dans l'art antérieur, des spatules dont la forme est spécifiquement adaptée au profilé de lisse dans lequel une tenture en tissus doit être insérée et retenue par friction. De telles spatules sont notamment décrites dans le document FR-A-2 728 001 ainsi que dans les brevets américains délivrés sous les numéros 4 018 260 , 4 151 762 , 4 197 686 , 4 549 334 , 4 625 490 , 4 986 332 .Also known in the prior art, spatulas whose shape is specifically adapted to the smooth section in which a fabric curtain must be inserted and retained by friction. Such spatulas are described in particular in the document FR-A-2,728,001 as well as in US patents issued under 4,018,260 , 4,151,762 , 4,197,686 , 4,549,334 , 4,625,490 , 4,986,332 .

L'usage des spatules décrites dans ces documents antérieurs s'avère impossible en pratique lorsque les nappes à tendre dans les lisses sont constituées par un film polymère de faible épaisseur (quelques centièmes de millimètres), soumis à des tensions élevées pour leur maintien plan dans un cadre de lisses de grandes dimensions (plusieurs dizaines de mètres carrés).The use of spatulas described in these prior documents proves impossible in practice when the sheets to be stretched in the smooth are constituted by a thin polymer film (a few hundredths of a millimeter), subjected to high tensions for their maintenance plan in a frame of smooth of large dimensions (several tens of square meters).

L'invention concerne plus particulièrement un outil manuel d'aide au montage de telles nappes de toile polymère à tendre dans un cadre de lisses, cette nappe étant pourvue sur sa périphérie d'une bordure en forme de crochet ou harpon ou d'une sur-épaisseur ou bourrelet devant être introduit dans le cadre de lisses.The invention more particularly relates to a manual tool for assisting in the assembly of such sheets of polymer fabric to be stretched in a heald frame, this sheet being provided on its periphery with a rim in the form of a hook or harpoon or a thickness or bead to be introduced in the framework of healds.

Ainsi qu'il est rappelé par exemple dans le document FR-A-2 691 193 , de manière conventionnelle, le matériau constituant de telles nappes tendues s'allonge lorsque la température s'élève, les dimensions de la nappe avant pose étant légèrement inférieures aux dimensions finales du faux plafond ou faux mur, le montage étant effectué à chaud.As is recalled for example in the document FR-A-2,691,193 in a conventional manner, the material constituting such stretched sheets lengthens when the temperature rises, the dimensions of the front ply is slightly lower than the final dimensions of the false ceiling or false wall, the mounting being carried out hot.

Les efforts à mettre en oeuvre lors de la pose de la nappe sont élevés, l'opérateur devant de plus travailler bras levés. Ces efforts sont également importants lorsque, le cas échéant, le montage est effectué à température ambiante.The efforts to be made during the laying of the sheet are high, the operator having to work more raised arms. These efforts are also important when, where appropriate, mounting is performed at room temperature.

Le document FR-A-2 310 450, de 1975 , rappelle que le montage de la nappe ou toile tendue dans le cadre de lisses s'effectue de la manière suivante (voir figure 10 de ce document antérieur):

  • insertion des angles de la nappe dans les profilés de lisse ;
  • puis insertion, à l'aide d'une spatule, de la bordure de nappe, entre les angles, définissant ainsi des zones de maintien intermédiaire ;
  • enfin, à l'aide d'une spatule ou d'une roulette glissant le long de la lisse, insertion de la nappe entre lesdites zones de maintien, le montage étant ainsi effectué de proche en proche.
The document FR-A-2,310,450, of 1975 recalls that the assembly of the web or canvas stretched in the framework of smooth is carried out as follows (see Figure 10 of this prior document):
  • inserting the corners of the web into the rail sections;
  • then inserting, with a spatula, the web edge, between the angles, thus defining intermediate holding zones;
  • finally, with the aid of a spatula or a roller sliding along the rail, insertion of the web between said holding zones, the assembly being thus carried out step by step.

Les zones de maintient intermédiaires sont définies, dans le document FR-A-2 310 450 , par des embrèvements disposés tous les 20cm environ sur la lisse, une distance de 10 à 12 cm étant proposée dans le document FR-A-2 475 093 .The intermediate maintenance zones are defined in the document FR-A-2,310,450 , by recesses arranged every 20cm approximately on the smooth, a distance of 10 to 12 cm being proposed in the document FR-A-2,475,093 .

Le repérage des embrèvements étant difficile pour un opérateur qui regarde la lisse par le dessous, lors du montage d'un faux plafond, il a été proposé de réaliser les embrèvements sur la bordure de nappe en forme de crochet (document FR-A-2 658 849 ). Mais cette disposition fragilise la nappe.The identification of the recesses being difficult for an operator who looks at the rail from below, when mounting a false ceiling, it has been proposed to make the recesses on the hook-shaped web edge (document FR-A-2,658,849 ). But this disposition weakens the tablecloth.

Plutôt que de réaliser des embrèvements sur les lisses ou le bord de la nappe, il a été envisagé dans l'art antérieur, de réduire les efforts lors de la mise en place de la nappe : les documents FR-A-2 692 302 et FR-A-2 699 613 issus de la demanderesse, proposent l'emploi d'une pièce permettant le maintien provisoire du bord de la nappe de plafond à faible distance du profilé de lisse. Ces pièces présentent toutefois l'inconvénient de ne pas permettre le premier accrochage de la nappe dans les angles du cadre de lisse.Rather than making recesses on the rails or the edge of the sheet, it has been envisaged in the prior art to reduce the forces during the setting up of the sheet: the documents FR-A-2 692 302 and FR-A-2,699,613 from the plaintiff, propose the use of a piece for the temporary maintenance of the edge of the ceiling ply at a short distance from the rail section. These parts, however, have the disadvantage of not allowing the first attachment of the sheet in the corners of the stringer frame.

Pour éviter la réalisation d'embrèvements, le document FR-A-2 691 193 propose l'emploi de spatules bilames supports conjuguées à des spatules ordinaires (figures 6a et 6b). Le montage s'effectue tout d'abord aux angles des murs à l'aide d'une spatule support d'angle bilame. La feuille de matière plastique de la nappe est maintenue en position tendue à l'aide de ces spatules bilames au-dessus d'un du profilé de lisse. A l'aide d'une spatule ordinaire, la pose consiste alors à faire glisser les lèvres de la bordure de la nappe de matière plastique sur l'épaulement de l'aile horizontale du profilé de lisse, la nappe étant maintenue tendue par les spatules bilames. Au fur et à mesure de l'ancrage de cette bordure, les spatules bilame supports sont enlevées.To avoid the realization of recesses, the document FR-A-2,691,193 proposes the use of bimetallic spatula supports conjugated with ordinary spatulas (Figures 6a and 6b). The assembly is done first at the corners of the walls using a bimetallic corner support spatula. The sheet of plastic material of the web is held in the extended position by means of these bimetallic spatulas above one of the rail section. Using an ordinary spatula, the pose then consists of sliding the lips of the edge of the sheet of plastic material on the shoulder of the horizontal flange of the rail section, the sheet being held taut by the spatulas bimetallic strips. As this border is anchored, the bimetallic spatulas are removed.

Le dispositif décrit dans ce document FR-A-2 691 193 présente de nombreux inconvénients :

  • un grand nombre de spatules bilames à arêtes rectilignes d'une part et arêtes faisant un angle entre elles d'autre part sont nécessaires pour effectuer la pose d'un faux plafond ou d'un faux mur ;
  • la réalisation de spatules bi-lames s'avère coûteuse, et ce d'autant que deux types de spatules sont nécessaires : spatules rectilignes d'une part et spatules à angle d'autre part.
The device described in this document FR-A-2,691,193 has many disadvantages:
  • a large number of bimetallic spatula with straight edges on the one hand and edges forming an angle between them on the other hand are necessary to perform the installation of a false ceiling or a false wall;
  • the realization of spatula bi-blades is expensive, and especially as two types of spatulas are needed: straight spatulas on the one hand and spatulas on the other hand.

L'invention vise à fournir un outil manuel d'aide au montage de nappes de toile polymère à tendre dans un cadre de lisses, cette nappe étant pourvue sur sa périphérie d'une bordure en forme de crochet ou harpon ou d'une sur-épaisseur ou bourrelet devant être introduit dans le cadre de lisses, l'outil ne présentant pas les inconvénients de ceux connus antérieurement et permettant à la fois :

  • le montage de la nappe et son maintien temporaire à la lisse, et ceci en toute portion du cadre, notamment aux angles de celui ci ;
  • le montage temporaire de cet outil en grand nombre, sur chantier, l'outil étant peu coûteux.
The aim of the invention is to provide a manual tool for assembling sheets of soft polymer cloth in a heald frame, this sheet being provided on its periphery with a rim in the form of a hook or a harpoon or an overlay. thickness or bead to be introduced into the framework of hedges, the tool does not have the disadvantages of those known previously and allowing:

Other objects and advantages of the invention will become apparent from the following description of embodiments, which description will be made with reference to the accompanying drawings, in which:
  • the figure 1 is a plan view of an editing aid, placed on one of its first large sides;
  • the figure 2 is a plan view of the tool represented in figure 1 posed on his other large side;

L'outil 1 représenté sur les figures comprend une première paroi 2 à bord libre avant 3 en forme de V et une deuxième paroi 4 pourvue de deux replis 5,6.The tool 1 shown in the figures comprises a first wall 2 free edge front 3 V-shaped and a second wall 4 provided with two folds 5,6.

La première paroi 2 et la deuxième paroi 4 sont sensiblement parallèles entre elles et reliées par une section 7 en forme de gouttière.The first wall 2 and the second wall 4 are substantially parallel to each other and connected by a section 7 in the form of a gutter.

Dans la forme de réalisation représentée, l'outil 1 est pourvu d'un plan de symétrie S sensiblement perpendiculaire aux figures 1 et 2. Cette symétrie est liée, ainsi qu'il apparaîtra plus complètement par la suite de cette description, à l'usage de cet outil 1 pour le montage de nappe de paroi tendue dans un angle de cadre.In the embodiment shown, the tool 1 is provided with a plane of symmetry S substantially perpendicular to the Figures 1 and 2 . This symmetry is linked, as will be apparent more fully later in this description, to the use of this tool 1 for mounting the wall sheet stretched in a corner frame.

L'outil 1 peut être réalisé en alliage métallique moulé ou en tôle pliée, ou bien encore en matériau polymère ou en composite.The tool 1 may be made of metal alloy molded or folded sheet, or even of polymeric material or composite.

On décrit maintenant plus complètement la première paroi 2.The first wall 2 is now more completely described.

Cette première paroi 2 comprend une partie extrême avant en forme de V, dont l'extrémité 9 est arrondie. Cet arrondi permet 9 permet d'éviter de blesser la bordure de la nappe lors de l'utilisation de l'outil. Pour la même raison, le bord libre 3 est dépourvu d'arête vive.This first wall 2 comprises a V-shaped front end portion, whose end 9 is rounded. This rounding allows 9 to avoid hurting the edge of the sheet when using the tool. For the same reason, the free edge 3 is devoid of sharp edge.

L'épaisseur de la première paroi 2 est sensiblement constante, dans le mode de réalisation représenté. Dans d'autres modes de réalisation, non représentés, l'épaisseur de la première paroi 2 va en augmentant de l'extrémité arrondie 9 vers la section 7. Cette disposition est avantageuse lorsque la bordure de la nappe à tendre dans le cadre est en forme de très petit harpon : la partie extrême arrondie et peu épaisse de la paroi 2 peut venir en appui dans le creux de ce harpon ou crochet, sans le blesser.The thickness of the first wall 2 is substantially constant, in the embodiment shown. In other embodiments, not shown, the thickness of the first wall 2 is increasing from the rounded end 9 to the section 7. This provision is advantageous when the edge of the sheet to be stretched in the frame is in very small harpoon shape: the rounded and slightly thick end portion of the wall 2 can bear in the hollow of this harpoon or hook, without hurting it.

La première paroi 2 comprend une partie extrême arrière dont les bords libres 10 sont sensiblement parallèles au plan S.The first wall 2 comprises a rear end portion whose free edges 10 are substantially parallel to the plane S.

Dans d'autres modes de réalisation, non représentés, la première paroi 2 comprend un bord libre avant en forme de V dont les deux branches ne sont pas d'égales longueur, cette disposition permettant d'utiliser l'outil dans des angles de cadre dont un des côtés est de faible dimensionIn other embodiments, not shown, the first wall 2 comprises a V-shaped free front edge whose two arms are not of equal length, this arrangement making it possible to use the tool in frame angles one of whose sides is small

Dans certains modes de réalisation, non représentés, le bord libre de la paroi 2 forme un V qui n'est pas sensiblement ouvert d'un angle A de 90° comme dans le mode de réalisation représenté, mais un angle supérieur ou inférieur à 90°. Cette disposition permet d'utiliser l'outil dans des angles de cadre différents de l'angle droit.In some embodiments, not shown, the free edge of the wall 2 forms a V which is not substantially open by an angle A of 90 ° as in the embodiment shown, but an angle greater than or less than 90 °. This arrangement allows the tool to be used in different frame angles of the right angle.

On décrit maintenant la deuxième paroi 4.The second wall 4 is now described.

Cette deuxième paroi 4 comprend une partie extrême avant dont l'extrémité 11 est sensiblement rectiligne et perpendiculaire au plan S. Cette extrémité 11 s'étend dans un plan P tangent à l'extrémité 9 de la première paroi 2, ainsi qu'il apparaît notamment en figure 2.This second wall 4 comprises a front end portion whose end 11 is substantially rectilinear and perpendicular to the plane S. This end 11 extends in a plane P tangent to the end 9 of the first wall 2, as it appears especially in figure 2 .

De part et d'autre du plan S, la deuxième paroi 4 comprend un bord ourlé ou replié en gouttière 5,6, le fond de ces replis 5,6 étant sensiblement parallèle au bord libre 3 de la première paroi 2, ces replis 5,6 saillant au-delà de ce bord libre 3, ainsi qu'il apparaît notamment en figure 2.On either side of the plane S, the second wall 4 comprises a hemmed or folded edge in groove 5,6, the bottom of these folds 5,6 being substantially parallel to the free edge 3 of the first wall 2, these folds 5 , 6 protruding beyond this free edge 3, as it appears in particular in figure 2 .

L'épaisseur de la deuxième paroi 4 est sensiblement constante, dans le mode de réalisation représenté.The thickness of the second wall 4 is substantially constant, in the embodiment shown.

La deuxième paroi 4 comprend une partie extrême arrière dont les bords libres 12 sont sensiblement parallèles au plan S.The second wall 4 comprises a rear end portion whose free edges 12 are substantially parallel to the plane S.

Dans d'autres modes de réalisation, non représentés, la deuxième paroi 4 comprend un bord libre avant en forme de V à replis 5,6, les branches de ce V n'étant pas d'égales longueur, cette disposition permettant d'utiliser l'outil dans des angles de cadre dont un des côtés est de faible dimension.In other embodiments, not shown, the second wall 4 comprises a free front edge V-shaped with folds 5.6, the branches of this V not being of equal length, this provision allowing to use the tool in the corners of a frame of which one of the sides is of small dimension.

Dans certains modes de réalisation, non représentés, le bord libre de la paroi 4 forme un V qui n'est pas sensiblement ouvert d'un angle B de 90° comme dans le mode de réalisation représenté, mais un angle supérieur ou inférieur à 90°. Cette disposition permet d'utiliser l'outil dans des angles de cadre différents de l'angle droit.In some embodiments, not shown, the free edge of the wall 4 forms a V which is not substantially open at an angle B of 90 ° as in the embodiment shown, but an angle greater than or less than 90 °. This arrangement allows the tool to be used in different frame angles of the right angle.

On se reporte maintenant à la figure 4.We are now going back to figure 4 .

Sur cette figure 4 est schématisée une toile 20 pour fausse cloison telle que par exemple faux mur ou faux plafond. Cette toile 20 est pourvue d'une bordure en forme de harpon ou crochet 21, par exemple soudée sur une largeur 22 de la toile 20.On this figure 4 is schematically a canvas 20 for false partition such as for example false wall or false ceiling. This fabric 20 is provided with a harpoon or hook-shaped rim 21, for example welded along a width 22 of the fabric 20.

La forme de la bordure 21 est complémentaire de celle du bord libre 3 de la première paroi 2. Dans le mode de réalisation représenté, le bord libre 3 est sensiblement plan et d'épaisseur constante, et vient en appui contre la face interne 23 de la bordure en crochet 21. Il est entendu toutefois que la nappe pourrait être pourvue d'une bordure de forme différente, par exemple d'une simple sur-épaisseur.The shape of the border 21 is complementary to that of the free edge 3 of the first wall 2. In the embodiment shown, the free edge 3 is substantially flat and of constant thickness, and abuts against the inner face 23 of the hook border 21. It is understood, however, that the web could be provided with a border of different shape, for example a simple over-thickness.

La bordure 21 de la nappe 20 est placée, à l'aide de l'outil 1, dans le profilé de lisse repéré 24.The edge 21 of the ply 20 is placed, with the aid of the tool 1, in the stringer section marked 24.

Ce placement est obtenu de la manière suivante :

  • une lame 25, par exemple une spatule conventionnelle est insérée sous la deuxième paroi 4 de sorte à venir en appui dans le fond des replis 5,6 (flèche F1). Dans le même temps ou dans une étape ultérieure, la bordure 21 de la nappe 20 est placée en appui contre le bord libre 3 de la première paroi 2 ;
  • l'opérateur exerce ensuite un effort sur la lame 25, effort dont la résultante F2 entraîne l'angle de la nappe 20 dans l'angle du cadre correspondant.
This investment is obtained as follows:
  • a blade 25, for example a conventional spatula is inserted under the second wall 4 so as to bear in the bottom of the folds 5,6 (arrow F1). At the same time or in a subsequent step, the edge 21 of the ply 20 is placed in abutment against the free edge 3 of the first wall 2;
  • the operator then exerts a force on the blade 25, effort whose resultant F2 causes the angle of the ply 20 in the corner of the corresponding frame.

Les angles A, B de l'outil 1 lorsqu'ils sont de sensiblement 90°, permettent d'exercer un effort sur deux côtés perpendiculaires de la nappe, facilitant grandement le placement de l'angle de nappe dans l'angle de cadre correspondant. Ainsi que le comprend l'homme du métier, un effet analogue peut être obtenu dès lors que les angles A et B sont sensiblement égaux à celui de l'angle de cadre considéré. Si seule la réalisation d'angles A, B de 90° environ est représentée, c'est simplement parc que cet angle droit est le plus fréquemment rencontré en pratique.The angles A, B of the tool 1 when they are substantially 90 °, make it possible to exert a force on two perpendicular sides of the ply, greatly facilitating the placement of the ply angle in the corresponding frame angle . As understood by those skilled in the art, a similar effect can be obtained since the angles A and B are substantially equal to that of the frame angle considered. If only the realization of angles A, B of about 90 ° is shown, it is simply that this right angle is the most frequently encountered in practice.

Le très faible prix de l'outil 1 permet d'envisager sa fabrication en grande série, selon diverses dimensions, divers angles A,B notamment.The very low price of the tool 1 allows to consider its mass production, according to various dimensions, various angles A, B in particular.

On se reporte maintenant à la figure 5.We are now going back to figure 5 .

Sur cette figure 5 est schématisée une section sensiblement rectiligne de profilé de lisse 30, par exemple fixée sur un mur ou une cloison 31. L'opérateur peut employer l'outil 1, dans cette autre configuration, en orientant l'outil de la manière représentée en figure 5, seule l'un des replis 5,6 servant à l'appui d'une lame telle que celle 25 représentée en figure 3. Un effort sur cette lame dont la résultante F est sensiblement perpendiculaire au profilé 30 permettra le placement de la bordure de nappe dans ce profilé.On this figure 5 is schematically a substantially straight section of smooth section 30, for example fixed on a wall or a partition 31. The operator can use the tool 1, in this other configuration, by orienting the tool as shown in FIG. figure 5 , only one of the folds 5, 6 serving to support a blade such as that represented in FIG. figure 3 . A force on this blade whose resultant F is substantially perpendicular to the profile 30 will allow the placement of the web edge in this section.

L'invention fournit ainsi un outil manuel d'aide au montage de nappes de toile polymère à tendre dans un cadre de lisses, cette nappe étant pourvue sur sa périphérie d'une bordure en forme de crochet ou harpon ou d'une sur-épaisseur ou bourrelet devant être introduit dans le cadre de lisses, l'outil ne présentant pas les inconvénients de ceux connus antérieurement et permettant à la fois :

  • le montage de la nappe et son maintien temporaire à la lisse, et ceci en toute portion du cadre, notamment aux angles de celui ci ;
  • le montage temporaire de cet outil en grand nombre, sur chantier, l'outil étant peu coûteux.
The invention thus provides a manual tool for assembling layers of soft polymer cloth in a heald frame, this web being provided on its periphery with a hook-shaped or harpoon-shaped rim or an over-thickness or bead to be introduced in the framework of smooth, the tool does not have the disadvantages of those known previously and allowing both:
  • the mounting of the web and its temporary maintenance to the smooth, and this in any portion of the frame, especially at the corners thereof;
  • the temporary assembly of this tool in large numbers on site, the tool is inexpensive.
