Description

L'invention se rapporte à une lame pour fermeture à rideau, ainsi qu'à un rideau de fermeture correspondant.The invention relates to a curtain-closing blade and a curtain corresponding closure.

Un tel rideau peut être utilisé par exemple pour des fermetures de mobilier.Such a curtain can be used for example for closures of furniture.

En particulier, les lames selon l'invention permettent de faciliter le positionnement des lames les unes par rapport aux autres lors de la fermeture du rideau tout en assurant une meilleure continuité de la surface apparente du rideau fermé et en offrant une protection accrue des liaisons souples entre les lames, notamment lorsque le rideau suit une courbe.In particular, the blades according to the invention make it possible to facilitate positioning the blades relative to each other during closure curtain while ensuring a better continuity of the apparent surface of the closed curtain and providing increased protection for flexible links between blades, especially when the curtain follows a curve.

On connaít déjà des lames pour rideau offrant une bonne protection des liaisons souples ci-dessus.Already known curtain blades offering good protection of the links soft above.

C'est le cas par exemple des brevets FR 2 716 696 et 2 687 724 de la demanderesse qui décrivent des rideaux dans lesquels les bords de deux lames adjacentes comportent une nervure et une rainure assurant le maintien en position relative des lames et empêchant l'insertion entre deux lames d'un outil susceptible de couper la liaison entre les lames.This is the case, for example, of patents FR 2 716 696 and 2 687 724 of the applicant who describe curtains in which the edges of two blades adjacent ones comprise a rib and a groove ensuring the maintenance in relative position of the blades and preventing the insertion between two blades of a tool likely to cut the connection between the blades.

Toutefois, un jeu apparaít rapidement entre la nervure et la rainure dès que les lames s'écartent légèrement par exemple lorsque le rideau suit une courbe.However, a game appears quickly between the rib and the groove as soon as the blades move slightly apart, for example when the curtain follows a curve.

Le document FR-2 737 751 décrit une lame profilée comprenant des moyens d'articulation de deux lames consécutives. Cependant ces moyens sont accessibles depuis l'extérieur du rideau notamment dans les zones ou les lames suivent une trajectoire courbe.Document FR-2 737 751 describes a profiled blade comprising articulation means of two consecutive blades. However these means are accessible from outside the curtain, particularly in areas where the blades follow a curved path.

Le document EP-0 635 619 décrit une lame profilée comprenant des moyens d'articulation de deux lames consécutives. La paroi frontale de cette lame comprend des extrémités saillantes permettant de protéger les moyens d'articulation en les rendant inaccessibles depuis l'extérieur des lamés. Cependant les moyens d'articulation sont situés au niveau de la paroi arrière de la lame, ce qui entraíne des frottements de ces moyens contre les rails de guidage du rideau et une usure prématurées de ces moyens.EP-0 635 619 discloses a profiled blade comprising articulation means of two consecutive blades. The front wall of this blade includes protruding ends to protect the means of articulation by rendering them inaccessible from outside the lamé. However, the articulation means are located at the level of the rear wall of the blade, which causes friction of these means against curtain guide rails and premature wear of these means.

La lame selon l'invention permet de remédier à ces inconvénients.The blade according to the invention overcomes these disadvantages.

A cet effet, un premier objet de l'invention est une lame profilée pour fermeture à rideau selon la revendication 1, comportant au moins un module à section droite polygonale, ledit module comportant deux parois respectivement frontale et arrière, raccordées par deux bords auxquels sont associés des moyens de liaison et d'articulation.For this purpose, a first object of the invention is a profiled blade for closing at curtain according to claim 1, comprising at least one polygonal cross-section module, said module having two walls respectively front and rear, connected by two edges with which are associated connecting means and articulation.

Les moyens de liaison et d'articulation de deux lames consécutives peuvent coopérer de manière que les deux lames puissent se trouver dans une position fermée où seule la paroi frontale est visible lorsque le rideau est fermé, et une position ouverte où les lames consécutives sont écartées les unes des autres. The connection and articulation means of two consecutive blades can cooperate so that the two blades can be in a position closed where only the front wall is visible when the curtain is closed, and a open position where the consecutive blades are spaced from each other.

La lame selon l'invention est caractérisée en ce que chaque module présente une extrémité de ladite paroi frontale saillant de la partie supérieure du bord adjacent de sorte que la partie souple des moyens de liaison et d'articulation ne dépasse pas ladite extrémité de la paroi frontale en position fermée, la partie supérieure dudit bord présentant une forme concave rejoignant tangentiellement l'extrémité de la paroi frontale, la concavité de cette dernière étant dirigée vers les moyens de liaison et d'articulation, l'autre extrémité de ladite paroi frontale se terminant par un épaulement sensiblement perpendiculaire à la paroi frontale de dimension sensiblement égale à l'extrémité du module adjacent, le bord adjacent à l'extrémité présentant une surface courbe en saillie de ladite surface, et la partie inférieure du bord rejoignant la paroi arrière suivant une surface de concavité dirigée vers le module adjacent, de sorte qu'en position fermée, l'extrémité de la paroi frontale d'une lame est en contact avec l'épaulement de la lame adjacente et prend appui sur une partie de la surface courbe en saillie dudit module adjacent.The blade according to the invention is characterized in that each module presents an end of said front wall protruding from the upper part of the edge adjacent, so that the flexible part of the connection and articulation means not exceed said end of the front wall in the closed position, the part upper edge of said edge having a concave shape tangentially joining the end of the front wall, the concavity of the latter being directed towards the connecting and articulation means, the other end of said front wall terminating in a shoulder substantially perpendicular to the front wall of dimension substantially equal to the end of the adjacent module, the edge adjacent the end having a curved surface projecting from said surface, and the lower part of the edge joining the rear wall along a surface of concavity directed towards the adjacent module, so that in the closed position, the end of the front wall of a blade is in contact with the shoulder of the adjacent blade and bears on a portion of the projecting curved surface of said adjacent module.

Ainsi en position fermée ou légèrement écartée des lames, la partie souple des moyens d'articulation est bien protégée des agressions extérieures.Thus in the closed position or slightly away from the blades, the flexible portion of means of articulation is well protected from external aggressions.

De plus, en position fermée, aucun jeu n'est visible entre les lames et/ou modules et les surfaces frontales des lames et/ou modules sont en continuité.In addition, in the closed position, no play is visible between the blades and / or modules and the front surfaces of the blades and / or modules are continuous.

Le fait qu'une partie de la surface frontale d'une lame prennent appui sur le bord d'une lame adjacente renforce par ailleurs la rigidité des lames en position fermée.The fact that part of the front surface of a blade is supported on the edge of an adjacent blade also reinforces the rigidity of the blades in position closed.

Dans une variante, en position fermée, les parties supérieures en regard de deux modules de lame sont sensiblement parallèles, l'extrémité de la partie supérieure du premier module étant proche de l'extrémité de la partie supérieure en regard du deuxième module de sorte que les moyens de liaison et d'articulation sont protégés. In a variant, in the closed position, the upper parts facing two blade modules are substantially parallel, the end of the part superior of the first module being close to the end of the upper part next to the second module so that the connection means and articulation are protected.

Les moyens de liaison et d'articulation peuvent comprendre deux extrémités rigides en matière non noble reliées entre elles par une charnière souple coextrudée avec la lame, au moins une extrémité rigide faisant partie du bord, l'autre extrémité présentant un moyen d'accrochage mâle ou faisant partie du bord d'un autre module de lame.The linking and articulation means may comprise two ends rigid non-noble material interconnected by a flexible hinge coextruded with the blade, at least one rigid end forming part of the edge, the other end having a male attachment means or part of the edge of another blade module.

Une partie du bord d'un module peut présenter un moyen d'accrochage femelle apte à recevoir un moyen d'accrochage mâle.A portion of the edge of a module may have a female fastening means adapted to receive a male hooking means.

Dans un autre mode de réalisation, la lame comporte deux modules reliés par une charnière souple, le bord du premier module étant opposé à la charnière souple et comportant un moyen d'accrochage femelle, le bord du deuxième module étant opposé à la charnière souple et comportant un moyen d'accrochage mâle.In another embodiment, the blade comprises two modules connected by a flexible hinge, the edge of the first module being opposite the hinge flexible and having a female hooking means, the edge of the second module being opposed to the flexible hinge and having a means male hanging.

Dans une variante, la lame comporte au moins trois modules sensiblement identiques reliés par des charnières souples, le bord d'un module terminal étant opposé à une charnière souple et comportant un moyen d'accrochage femelle, le bord de l'autre module terminal étant opposé à une charnière souple et comportant un moyen d'accrochage mâle, le(s) module(s) central(aux) étant relié(s) aux modules terminaux par des charnières souples.In a variant, the blade comprises at least three modules substantially identical ones connected by flexible hinges, the edge of a terminal module being opposed to a flexible hinge and comprising a female hooking means, the edge of the other terminal module being opposed to a flexible hinge and comprising a male coupling means, the central module (s) being connected to the terminal modules by flexible hinges.

Un autre objet de l'invention est un rideau de fermeture caractérisé en ce qu'il est réalisé par assemblage des lames décrites précédemment, les lames étant assemblées les unes aux autres et à la suite des autres par coopération des moyens d'accrochage mâle et femelle.Another object of the invention is a closing curtain characterized in that is made by assembling the blades described above, the blades being assembled together and after the others by cooperation of the male and female hooking means.

Dans un mode de réalisation, le rideau comporte une lame terminale comportant un moyen d'accrochage femelle apte à coopérer directement avec un moyen d'accrochage mâle d'une lame.In one embodiment, the curtain comprises a terminal blade comprising a female coupling means adapted to cooperate directly with a means male hooking a blade.

    • Une lame profilée 1 pour fermeture à rideau selon l'invention est maintenant décrite en référence aux figures 1 et 2.A profiled blade 1 for a curtain closure according to the invention is now described with reference to Figures 1 and 2.

    La lame profilée 1 comporte au moins un module 2 à section droite polygonale.The profiled blade 1 comprises at least one module 2 polygonal cross section.

    Ledit module 2 comporte deux parois 3, 4 respectivement frontale et arrière, raccordées par deux bords 5, 6.Said module 2 comprises two walls 3, 4 respectively front and rear, connected by two edges 5, 6.

    Des moyens 7 de liaison et d'articulation sont associés aux bords 5, 6. Means 7 of connection and articulation are associated with the edges 5, 6.

    Dans les modes de réalisation représentés sur les figures 2 et 3, chaque lame comporte deux modules 2 associés par des moyens 7 de liaison et d'articulation.In the embodiments shown in FIGS. 2 and 3, each blade comprises two modules 2 associated by connecting means 7 and hinge.

    Les moyens 7 de liaison et d'articulation de deux lames 1 et/ou modules 2 consécutifs peuvent coopérer de manière que les deux lames 1 puissent se trouver dans une position fermée où seule la paroi frontale 3 est visible lorsque le rideau est fermé, et une position ouverte où les lames consécutives sont écartées les une des autres.The means 7 for connecting and articulating two blades 1 and / or modules 2 consecutive devices can cooperate so that the two blades 1 can be find in a closed position where only the front wall 3 is visible when the curtain is closed, and an open position where the consecutive blades are apart from each other.

    La position fermée correspond par exemple aux figures 2 et 3, et la position ouverte aux figures 4 et 5 lorsque les lames 1 suivent une courbe.The closed position corresponds for example to FIGS. 2 and 3, and the position open to Figures 4 and 5 when the blades 1 follow a curve.

    La paroi frontale 3 présente deux extrémités opposées 3a et 3b visibles sur la figure 1.The front wall 3 has two opposite ends 3a and 3b visible on the figure 1.

    Une première extrémité 3a de ladite paroi frontale 3 saille de la partie supérieure 6a du bord adjacent 6 à ladite extrémité 3a.A first end 3a of said front wall 3 protrudes from the upper part 6a of the adjacent edge 6 at said end 3a.

    La longueur en saillie de l'extrémité 3a est telle que la partie souple des moyens 7 de liaison et d'articulation ne dépassent pas ladite extrémité 3a de la paroi frontale en position fermée des lames 1, tel que représenté sur les figures 1 à 3.The protruding length of the end 3a is such that the flexible part of the means 7 of connection and articulation do not exceed said end 3a of the wall front in the closed position of the blades 1, as shown in Figures 1 to 3.

    La partie supérieure 6a dudit bord 6 présente une forme concave rejoignant tangentiellement l'extrémité 3a de la paroi frontale 3. La concavité de cette partie 6a est dirigée vers les moyens 7 de liaison et d'articulation dudit module 2.The upper part 6a of said edge 6 has a concave shape joining tangentially the end 3a of the front wall 3. The concavity of this part 6a is directed towards the means 7 for connecting and articulating said module 2.

    L'autre extrémité 3b de ladite paroi frontale 3 se termine par un épaulement 8 sensiblement perpendiculaire à la paroi frontale 3 (figures 1 à 3).The other end 3b of said front wall 3 ends with a shoulder 8 substantially perpendicular to the front wall 3 (Figures 1 to 3).

    Cet épaulement 8 est de dimension sensiblement égale à l'extrémité 3a d'un module 2 adjacent. This shoulder 8 is of dimension substantially equal to the end 3a of a adjacent module 2.

    Le bord 5 adjacent à l'extrémité 3b présente une surface courbe en saillie 5a dudit épaulement 8 et à proximité de ce dernier. La partie inférieure 5b du bord 5 rejoigne la paroi arrière 4 suivant une surface de concavité dirigée vers le module adjacent 2.The edge 5 adjacent to the end 3b has a curved surface 5a protruding of said shoulder 8 and close to the latter. The lower part 5b of the edge 5 joins the rear wall 4 along a concavity surface directed towards the adjacent module 2.

    Ainsi, en position fermée, l'extrémité 3a de la paroi frontale 3 et la partie supérieure 6b du bord 6 d'un premier module 2 reposent partiellement sur la surface courbe en saillie 5a du bord 5 et l'extrémité 3a est en contact avec l'épaulement 8 d'un deuxième module 2 adjacent au premier module.Thus, in the closed position, the end 3a of the front wall 3 and the part upper 6b of the edge 6 of a first module 2 rest partially on the curved surface protruding 5a of the edge 5 and the end 3a is in contact with the shoulder 8 of a second module 2 adjacent to the first module.

    Cette configuration renforce la solidité des lames assemblées entre elles et assure la continuité des surfaces frontales des lames adjacentes améliorant ainsi la finition de l'ensemble.This configuration reinforces the strength of the blades assembled together and ensures the continuity of the frontal surfaces of the adjacent blades improving thus the finish of the whole.

    Les parties en saillie 6a et 5a des bords facilitent par ailleurs la position correcte des modules 2 les uns par rapport aux autres lors de leur passage entre les positions fermée et ouverte.The projecting portions 6a and 5a of the edges also facilitate the correct position modules 2 relative to each other during their passage between closed and open positions.

    La partie supérieure 5a du bord 5 d'un module 2 peut en effet servir de guidage pour l'extrémité 3a du module 2 adjacent lorsque ce dernier se rapproche ou s'éloigne du premier module suivant une courbe.The upper part 5a of the edge 5 of a module 2 can indeed serve as a guide for the end 3a of the adjacent module 2 when the latter is approaching or away from the first module following a curve.

    En position fermée, les parties supérieures 5a, 6a des bords en regard de deux modules de lame sont sensiblement parallèles, l'extrémité de la partie 5a opposée à l'épaulement 8 étant proche de l'extrémité de la partie supérieure 6a de sorte que les moyens de liaison et d'articulation 7 sont protégés.In the closed position, the upper parts 5a, 6a of the edges facing two blade modules are substantially parallel, the end of the part 5a opposite the shoulder 8 being close to the end of the upper part 6a so that the connection and articulation means 7 are protected.

    Il est ainsi difficile, voire impossible de passer une lame tranchante entre deux lames 1 de rideau adjacentes et de couper les moyens de liaison et d'articulation 7.It is thus difficult or impossible to pass a sharp blade between two adjacent curtain blades 1 and cut the connecting means and articulation 7.

    Dans un mode de réalisation représenté sur les figures 1 et 2, les moyens de liaison et d'articulation 7 sont fixés sur les parties inférieures 5b, 6b des bords 5, 6, à proximité des parties supérieures 5a, 6a desdits bords. In an embodiment shown in FIGS. 1 and 2, the means of link and articulation 7 are fixed on the lower parts 5b, 6b of the edges 5, 6, near the upper parts 5a, 6a of said edges.

    Dans un autre mode de réalisation représenté sur la figure 3, les moyens de liaison et d'articulation 7 sont fixés sur les parties inférieures 5b, 6b des bords 5, 6 dans la moitié inférieure des lames 1.In another embodiment shown in FIG. 3, the means of link and articulation 7 are fixed on the lower parts 5b, 6b of the edges 5, 6 in the lower half of the blades 1.

    Les moyens de liaison et d'articulation 7 sont alors plus difficiles à atteindre de l'extérieur. Ils sont en effet protégés par les parties supérieures 5a, 6a, et plus précisément par la partie supérieure 5a lorsque le rideau suit une courbe (figures 6 et 7).The linking and articulation means 7 are then more difficult to reach from outside. They are indeed protected by the upper parts 5a, 6a, and more precisely by the upper part 5a when the curtain follows a curve (Figures 6 and 7).

    Les moyens de liaison et d'articulation 7 comprennent deux extrémités rigides 9a, 9b en matière non noble reliées entre elles par une charnière souple 10 coextrudée avec la lame 1, tel que représenté sur la figure 1.The connecting and articulation means 7 comprise two rigid ends 9a, 9b non-noble material interconnected by a flexible hinge 10 coextruded with the blade 1, as shown in Figure 1.

    Au moins une extrémité rigide 9a desdits moyens 7 fait partie de la partie inférieure d'un bord 5b, 6b.At least one rigid end 9a of said means 7 is part of the part bottom of an edge 5b, 6b.

    L'autre extrémité 9b présente un moyen d'accrochage mâle 11 tel que sur la figure 1 ou fait partie du bord 5b, 6b d'un autre module 2 de lame tel que par exemple sur la figure 2.The other end 9b has a male attachment means 11 such as on the 1 or part of the edge 5b, 6b of another module 2 blade such as by example in Figure 2.

    La partie inférieure 5b du bord 5 d'un module présente un moyen d'accrochage femelle 12 apte à recevoir un moyen d'accrochage mâle 11 du module adjacent (figures 2 et 3).The lower part 5b of the edge 5 of a module has a hooking means female 12 adapted to receive a male coupling means 11 of the adjacent module (Figures 2 and 3).

    En fait sur un même module 2, le bord présentant le moyen d'accrochage femelle 12 est opposé au bord présentant un moyen d'accrochage mâle 11 ou une simple liaison par charnière souple 10.In fact on the same module 2, the edge having the attachment means female 12 is opposite the edge having a male attachment means 11 or a simple connection by flexible hinge 10.

    Ainsi, dans le cas où une lame 1 est formée d'un seul module 2 (figure 1), un premier bord, par exemple le bord 5, présente un moyen d'accrochage femelle 12, tandis que le bord opposé 6 présente un moyen d'accrochage mâle 11 relié au bord par une charnière souple 10. Thus, in the case where a blade 1 is formed of a single module 2 (FIG. first edge, for example the edge 5, has a female fastening means 12, while the opposite edge 6 has a male fastening means 11 connected at the edge by a flexible hinge 10.

    Dans le cas où une lame 1 est formée de deux modules 2 (figure 2), un premier bord 5 du premier module présente un moyen d'accrochage femelle 12. Le second bord 6 de ce premier module est relié au premier bord 5 du second module par une charnière souple 10 solidaire de deux extrémités rigides 9a, 9b. Le second bord 6 du second module porte alors un moyen d'accrochage mâle 11 relié au bord par une charnière souple 10.In the case where a blade 1 is formed of two modules 2 (FIG. 2), a first edge 5 of the first module has a female coupling means 12. The second edge 6 of this first module is connected to the first edge 5 of the second module by a flexible hinge 10 secured to two rigid ends 9a, 9b. The second edge 6 of the second module then carries a male fastening means 11 connected to the edge by a flexible hinge 10.

    Il va de soi que l'on pourrait inverser la position des moyens d'accrochage mâle et femelle sur les bords des modules 2.It goes without saying that one could reverse the position of the male fastening means and female on the edges of the modules 2.

    Dans les modes de réalisation représenté sur les figures, le moyen d'accrochage mâle 11 est un jonc en matériau rigide. Le moyen d'accrochage femelle 12 présente un logement réalisé d'un seul tenant avec la partie inférieure du bord 5 de forme complémentaire avec le jonc en matériau rigide. Ce logement présente une ouverture vers l'extérieur permettant l'insertion du jonc 11.In the embodiments shown in the figures, the means male fastening 11 is a rod made of rigid material. The hooking means female 12 has a housing made in one piece with the part lower edge 5 of complementary shape with the rod of rigid material. This housing has an opening to the outside allowing the insertion of the ring 11.

    Dans le mode de réalisation représenté sur la figure 3, le moyen d'accrochage femelle 12 est formé par les parties inférieures et supérieures d'un bord.In the embodiment shown in FIG. 3, the hooking means female 12 is formed by the lower and upper parts of an edge.

    Ainsi, la partie supérieure 5a d'un module forme la partie supérieure du moyen d'accrochage femelle dudit module, la partie inférieure dudit moyen d'accrochage femelle étant formé par une surface de concavité 5c dirigée vers l'intérieur du moyen d'accrochage femelle 12, ladite surface 5c saillant sensiblement perpendiculairement du bord inférieur 5b du module.Thus, the upper part 5a of a module forms the upper part of the means hooking said module, the lower part of said means female coupling being formed by a 5c concavity surface directed towards inside the female attachment means 12, said surface 5c salient substantially perpendicular to the lower edge 5b of the module.

    Le logement formé par les surfaces 5a et 5c peuvent ainsi accueillir un moyen d'accrochage mâle 11.The housing formed by the surfaces 5a and 5c can thus accommodate a means male hooking 11.

    On peut également prévoir une surface 5d saillant de la partie supérieure 5a du bord 5 à proximité de la partie inférieure 5b. Cette surface 5d s'étendant sensiblement suivant une direction parallèle aux parois 3, 4 de façon à augmenter la protection de la charnière souple 10 (figure 2). It is also possible to provide a projecting surface 5d of the upper part 5a of the edge 5 near the bottom 5b. This surface 5d extending substantially in a direction parallel to the walls 3, 4 so as to increase the protection of the flexible hinge 10 (Figure 2).

    Le mode de réalisation décrit ci-dessus peut également être employé pour des lames comportant un seul module 2.The embodiment described above can also be used for blades having a single module 2.

    Dans le mode de réalisation représenté sur la figure 4, chaque lame 1 comporte trois modules 2 sensiblement identiques reliés par des charnières souples 10. Le bord 5b d'un module terminal opposé à sa charnière souple 10 comporte un moyen d'accrochage femelle 12, le bord 6b de l'autre module terminal étant opposé à sa charnière souple 10 et comportant un moyen d'accrochage mâle 11. Le module central est relié aux modules terminaux par des charnières souples 10.In the embodiment shown in FIG. 4, each blade 1 comprises three substantially identical modules 2 connected by flexible hinges 10. The edge 5b of a terminal module opposite its flexible hinge 10 has a female coupling means 12, the edge 6b of the other terminal module being opposite its flexible hinge 10 and comprising a male attachment means 11. The central module is connected to the terminal modules by hinges flexible 10.

    Dans d'autres modes de réalisation non représentés, chaque lame comporte au moins trois modules 2 et comporte un ou plusieurs modules centraux.In other embodiments, not shown, each blade comprises at least one minus three modules 2 and includes one or more central modules.

    Les modules 2 utilisés pour ce type de lames 1 peuvent être tels que décrits précédemment et représentés sur les figures 1 à 3.The modules 2 used for this type of blade 1 may be as described previously and shown in Figures 1 to 3.

    Une lame peut comporter trois modules 2, dont au moins un des modules 2 présente une forme différente des deux autres.A blade may comprise three modules 2, including at least one of the modules 2 has a different shape from the other two.

    Dans une variante, une lame comporte trois modules 2, dont au moins un des modules 2 tel que décrit précédemment.In a variant, a blade comprises three modules 2, at least one of which modules 2 as described above.

    Dans la variante représentée figure 4, le module 2 correspondant aux modules décrits et représentés sur les figures 1 à 3 est le module central : les bords supérieurs 5a, 6a du module terminal comportant un moyen d'accrochage mâle 11 étant sensiblement identiques et symétriques et présentant deux extrémités 3a, 3b de ladite paroi frontale 3 saillant de la partie supérieure 5a, 6a de leurs bords adjacents 5, 6 de sorte que les moyens 7 de liaison et d'articulation ne dépassent pas lesdites extrémités 3a, 3b de la paroi frontale en position fermée.In the variant shown in FIG. 4, the module 2 corresponding to the modules described and represented in FIGS. 1 to 3 is the central module: the edges upper 5a, 6a of the terminal module comprising a male coupling means 11 being substantially identical and symmetrical and having two ends 3a, 3b of said front wall 3 protruding from the upper portion 5a, 6a of their adjacent edges 5, 6 so that the means 7 of connection and articulation do not do not exceed said ends 3a, 3b of the front wall in the closed position.

    La partie supérieure 5a, 6a de chaque bord 5, 6 présente une forme concave rejoignant tangentiellement l'extrémité 3a, 3b de la paroi frontale, la concavité de cette dernière étant dirigée vers les moyens 7 de liaison. The upper part 5a, 6a of each edge 5, 6 has a concave shape tangentially joining the end 3a, 3b of the front wall, the concavity the latter being directed towards the connecting means 7.

    Dans cette variante, le bord supérieur 5a du module terminal comportant un moyen d'accrochage femelle 12 est sensiblement perpendiculaire à la paroi frontale 3 dudit module, le bord supérieur 5a comportant une surface saillante destinée à protéger la charnière.In this variant, the upper edge 5a of the terminal module comprising a female coupling means 12 is substantially perpendicular to the wall front 3 of said module, the upper edge 5a having a projecting surface intended to protect the hinge.

    L'autre extrémité de ladite paroi frontale 3 dudit module terminal se termine alors par un épaulement 8 sensiblement perpendiculaire à la paroi frontale de dimension sensiblement égale à l'extrémité du module adjacent et présentant une surface courbe en saillie 6a dudit épaulement 8, et la partie inférieure 6b du bord rejoignant la paroi arrière 4 suivant une surface de concavité dirigée vers le module adjacent, de sorte qu'en position fermée, l'extrémité 3b de la paroi frontale d'une lame est en contact avec l'épaulement 8 de la lame adjacente et prend appui sur une partie de la surface courbe en saillie 5a dudit module adjacent.The other end of said front wall 3 of said terminal module ends then by a shoulder 8 substantially perpendicular to the front wall of dimension substantially equal to the end of the adjacent module and presenting a projecting curved surface 6a of said shoulder 8, and the lower portion 6b of edge joining the rear wall 4 according to a concavity surface directed towards the adjacent module, so that in the closed position, the end 3b of the wall front of a blade is in contact with the shoulder 8 of the adjacent blade and is supported on a portion of the projecting curved surface 5a of said module adjacent.

    Il va de soi que les positions des moyens d'accrochage mâle et femelle et les bords correspondant des modules peuvent être inversées.It goes without saying that the positions of the male and female hooking means and the corresponding edges of the modules can be reversed.

    Les différents modules décrits dans la description précédente peuvent être utilisés pour des lames à un, deux, trois modules 2, voire plus. On peut par exemple réaliser des lames à cinq modules 2.The different modules described in the previous description can be used for blades with one, two, three modules 2 or more. We can example to make blades with five modules 2.

    Une lame 1 peut être réalisée par coextrusion de deux matières plastiques différentes, la paroi frontale visible 3 et les parties supérieures 5a, 6a des bords 5, 6 adjacentes à ladite paroi frontale étant d'une matière vierge spécifique, la paroi arrière 4 et les parties inférieures 5b, 6b des bords 5, 6 adjacentes à la dite paroi arrière étant en matière standard ou de deuxième choix.A blade 1 can be made by coextrusion of two plastics different, the visible front wall 3 and the upper parts 5a, 6a of the edges 5, 6 adjacent to said front wall being of a specific virgin material, the rear wall 4 and the lower parts 5b, 6b of the edges 5, 6 adjacent to the said rear wall being standard material or second choice.

    Si bien qu'une lame 1 comportant un, deux, trois modules ou plus est réalisée en une étape par coextrusion de trois matières différentes : les matières plastiques rigides noble et non noble et la matière plastique souple formant les charnières souples. So that a blade 1 having one, two, three or more modules is made in one step by coextrusion of three different materials: rigid plastics noble and not noble and the flexible plastic material forming the flexible hinges.

    Un autre objet de l'invention est un rideau de fermeture réalisé par assemblage des lames 1 décrites ci-dessus, les lames 1 étant assemblées les unes aux autres et à la suite des autres par coopération des moyens d'accrochage mâle 11 et femelle 12.Another object of the invention is a closure curtain made by assembling blades 1 described above, the blades 1 being assembled one to the other and as a result of others by cooperation of male hooking means 11 and female 12.

    Dans un mode de réalisation, le rideau comporte une lame terminale 13 comportant un moyen d'accrochage femelle 14 apte à coopérer directement avec un moyen d'accrochage mâle 11 d'une lame 1, tel que représenté figures 2 et 3.In one embodiment, the curtain has a terminal blade 13 comprising a female coupling means 14 able to cooperate directly with a male attachment means 11 of a blade 1, as shown in FIG. 2 and 3.

    On pourrait également envisager de remplacer le moyen d'accrochage femelle 14 de la lame 13 par un moyen d'accrochage mâle apte à coopérer avec des moyens d'accrochage femelle 12 des lames 1.We could also consider replacing the female hooking means 14 of the blade 13 by a male coupling means adapted to cooperate with female coupling means 12 of the blades 1.

    De façon similaire à une lame 1, le bord 15 de la lame terminale 13 à proximité du bord 6 de la lame adjacente présente une surface 16 saillant vers la partie supérieure 6a dudit bord 6.In a similar manner to a blade 1, the edge 15 of the terminal blade 13 in the vicinity of the edge 6 of the adjacent blade has a surface 16 projecting towards the part upper 6a of said edge 6.

    Dans le mode de réalisation représenté sur les figures 2 à 4, la surface 16 est sensiblement parallèle à la partie supérieure 6a du bord de la lame voisine de sorte à protéger la charnière souple 10 sur laquelle est fixé le moyen d'accrochage mâle 11 de la lame 2.In the embodiment shown in FIGS. 2 to 4, the surface 16 is substantially parallel to the upper portion 6a of the edge of the blade adjacent to so as to protect the flexible hinge 10 on which is fixed the means male hooking 11 of the blade 2.

    Dans un autre mode de réalisation représenté figure 5, la surface 16 est sensiblement parallèle à la paroi frontale 17 de la lame 13.In another embodiment shown in FIG. 5, the surface 16 is substantially parallel to the front wall 17 of the blade 13.

    Cette surface 16 peut également contribuer à la mise en place correcte de la lame 1 par rapport à la lame terminale 13 lors de la fermeture du rideau. Elle assure également, la protection des moyens de liaison et d'articulation 7 du module 2 adjacent, notamment lorsque le rideau suit une courbe.This surface 16 can also contribute to the correct placement of the blade 1 relative to the terminal blade 13 when closing the curtain. She also ensures the protection of the connection and articulation means 7 of the module 2 adjacent, especially when the curtain follows a curve.

    La paroi frontale 17 de la lame terminale 13 s'étend sensiblement dans la même direction que la paroi frontale 3 de la lame 1 adjacente et dont l'extrémité est en contact avec l'extrémité 3a de la paroi frontale de ladite lame lorsque les lames 1, 13 sont en position fermée, de sorte qu'aucun jour n'est visible entre la lame terminale 13 et la lame adjacente 1.The front wall 17 of the terminal blade 13 extends substantially in the same direction direction that the front wall 3 of the adjacent blade 1 and whose end is in contact with the end 3a of the front wall of said blade when the blades 1, 13 are in the closed position, so that no day is visible between the blade terminal 13 and the adjacent blade 1.

    La lame terminale 13 peut être un profilé ouvert réalisé par pliage d'une tôle métallique.The end plate 13 may be an open profile produced by folding a sheet metallic.

    Cette lame terminale 13 peut également être réalisée par emboutissage ou tout autre méthode équivalente. Elle pourrait également être un profilé fermé.This terminal blade 13 can also be made by stamping or all another equivalent method. It could also be a closed profile.

    Toute autre matière rigide et résistante apte à être mise en forme pourrait être utilisée pour la réalisation de cette lame terminale.Any other rigid and resistant material suitable for being shaped could be used for the realization of this terminal blade.

    Dans un autre mode de réalisation représenté figure 4, la lame terminale 13 comprend un renfort 18 matière rigide telle qu'une tôle métallique, recouvert d'un habillage 19.In another embodiment shown in FIG. 4, the terminal blade 13 comprises a reinforcement 18 rigid material such as a metal sheet, covered a dressing 19.

    Ce renfort 18 peut toutefois être en tout autre matériau suffisamment rigide et apte à être recouvert d'un habillage 19.This reinforcement 18 may, however, be in any other sufficiently rigid material and apt to be covered with a covering 19.

    Dans le mode de réalisation représenté, le renfort 18 est solidaire de l'habillage 19 sur toute surface interne de ce dernier excepté au niveau du moyen d'accrochage 14 et de la surface saillante 16 qui font partie de l'habillage 19.In the embodiment shown, the reinforcement 18 is integral with the casing 19 on any internal surface of the latter except at the level of the medium hooking 14 and the projecting surface 16 which form part of the covering 19.

    La face 20 de la lame 13, sensiblement parallèle à la paroi frontale 17, peut être constituée uniquement du renfort 18, sans habillage 19.The face 20 of the blade 13, substantially parallel to the front wall 17, can be consisting only of the reinforcement 18, without covering 19.

    Cet habillage 19 permet d'améliorer l'aspect visuel de la lame terminale 13 sans en affaiblir la résistance.This covering 19 makes it possible to improve the visual appearance of the terminal blade 13 without to weaken the resistance.

    L'habillage 19 peut être en matière plastique identique à la matière plastique de la paroi frontale 3 des autres lames du rideau. Il peut être également en une autre matière d'aspect visuel agréable et suffisamment résistant. The covering 19 may be made of plastic identical to the plastic material of the front wall 3 of the other blades of the curtain. It can also be in one another material with a pleasant and sufficiently resistant visual appearance.

    Une lame terminale 13 avec ou sans renfort 18 peut être utilisée avec tous les types de lames et de modules décrits précédemment.A terminal blade 13 with or without reinforcement 18 can be used with all types of blades and modules previously described.

    Une partie du rideau formé par l'assemblage des lames 1 selon un mode de réalisation de l'invention est représentée en situation de virage dans une glissière 21 sur la figure 6 et dans une glissière à 180° sur la figure 5.Part of the curtain formed by the assembly of the blades 1 according to a method of embodiment of the invention is shown in a cornering situation in a slide 21 in FIG. 6 and in a slide at 180 ° in FIG.

    La configuration des lames 1 permet de conserver une bonne protection des articulation lorsque les lames sont légèrement écartées les unes des autres. L'espacement entre deux lames ou modules formant une sorte de S jusqu'à l'articulation, les parties supérieures 5a servant de bouclier de protection des moyens de liaison et d'articulation.The configuration of the blades 1 makes it possible to preserve a good protection of the articulation when the blades are slightly apart from each other. The spacing between two blades or modules forming a kind of S up to the articulation, the upper parts 5a serving as a shield for protecting the connecting and articulation means.

    Il est clair d'après les figures 6 et 7 que la forme bombée des faces frontale 3 et arrière 4 d'un module permettent de réduire les frottements contre la glissière 21 en réduisant les surfaces de contact.It is clear from FIGS. 6 and 7 that the curved shape of the front faces 3 and rear 4 of a module can reduce friction against the slide 21 by reducing the contact surfaces.

    Ces surfaces peuvent toutefois être sensiblement plane ou présenter une autre forme sans sortir du cadre de l'invention.These surfaces can, however, be substantially flat or present another form without departing from the scope of the invention.

    6. A slat according to one of Claims 1 to 5, characterised in that it comprises two modules (2) connected together by a flexible hinge (10), the edge (5b) of the first module being opposite to the flexible hinge (10) and comprising a female attachment means (12), the edge (6b) of the second module being opposite to the flexible hinge and comprising a male attachment means (11).
    7. A slat according to one of Claims 1 to 5, characterised in that it comprises at least three substantially identical modules (2) connected by flexible hinges (10), the edge (5b) of an end module being opposite to its flexible hinge (10) and comprising a female attachment means (12), the edge (6b) of the other end module being opposite to its flexible hinge and comprising a male attachment means (11), the central module or modules being connected to the end modules by flexible hinges (10).
    8. A slat according to one of Claims 1 to 5, characterised in that it comprises at least three modules (2), the said modules being connected by flexible hinges (10), the edge (5b) of an end module being opposite to its flexible hinge (10) and comprising a female attachment means (12), the edge (6b) of the other end module being opposite to its flexible hinge and comprising a male attachment means (11), the central module or modules being connected to the end modules by flexible hinges (10), at least one of the modules (2) having a shape different from the other two.
    9. A slat according to one of Claims 1 to 5, characterised in that it comprises at least three modules (2), the said modules being connected by flexible hinges (10), the edge (5b) of an end module being opposite to its flexible hinge (10) and comprising a female attachment means (12), the edge (6b) of the other end module being opposite to its flexible hinge and comprising a male attachment means (11), the central module or modules being connected to the end modules by flexible hinges (10), two of the said modules (2) having a different shape.
    10. A slat according to Claims 8 or 9, characterised in that the top edges (5a, 6a) of the end module comprising a male attachment means (11) are substantially identical and symmetrical and have two ends (3a, 3b) of the said front wall (3) projecting from the top part (5a, 6a) of their adjacent edges (5, 6) so that the connection and articulation means (7) do not project beyond the said ends (3a, 3b) of the front wall in the closed position, the top part (5a, 6a) of each edge (5, 6) having a concave shape tangentially joining the ends (3a, 3b) of the front wall, the concavity of the latter being directed towards the connection means (7).
    11. A slat according to one of Claims 8 to 10, characterised in that the top edge, (5a) of the end module comprising a female attachment means (12) is substantially perpendicular to the front wall (3) of the said module, the top edge (5a) comprising a projecting surface intended to protect the hinge, the other end of the said front wall (3) of the said end module ending in a shoulder (8) substantially perpendicular to the front wall with a size substantially equal to the end of the adjacent module and having a curved surface (6a) projecting from the said shoulder (8), and the bottom part (6b) of the edge adjoining the rear wall (4) along a concavity surface directed towards the adjacent wall, so that, in the closed position, the end (3b) of the front wall of a slat is in contact with the shoulder (8) of the adjacent slat and bears on a part of the projecting curved surface (5a) of the said adjacent module.
