Abstract

The roller blind comprises an assembly of profiled strips (1) having a hollow trapezoidal transverse section (2). The strips have a flexible inextensible pivoting band (14). The section has a large base (3), visible from the outside, connected to a small base (4) by first (5) and second (6) side walls. The section has one or more reinforcing partitions (16) connecting the two bases. A cylindrical housing (10) located at the corner of the small base receives an adjacent strip ring (15) connected to the strip by the flexible band. The housing has an opening (11) parallel to the bases re-entrant into the first side wall. The housing wall has two diametrically opposite parts free from all restrictions. These enable diametral support by a tool, intended to allow deformation of the housing in order to lock axial sliding of the ring fitting in the housing.

Description

L'invention concerne une lame profilée pour fermeture à rideau, un rideau de fermeture comportant de telles lames, son procédé de réalisation.The invention relates to a profiled blade for curtain closing, a closing curtain comprising such blades, its production method.

Il existe déjà des fermetures à rideau comportant des lames profilées présentant sur un bord longitudinal un élément d'articulation mâle en cylindre fermé et sur le bord longitudinal opposé un élément d'articulation femelle en cylindre ouvert. Ces deux éléments sont adaptés pour coopérer avec les éléments correspondants des lames adjacentes de manière à permettre le pivotement relatif autour de l'axe commun aux deux éléments coopérant. Lorsque le rideau est fermé, sa face frontale est sensiblement plane, et les bords longitudinaux frontaux de deux lames adjacentes ne sont séparés que par une fente étroite.There are already curtain closures comprising profiled blades having on a longitudinal edge a male articulation element in a closed cylinder and on the opposite longitudinal edge a female articulation element in an open cylinder. These two elements are adapted to cooperate with the corresponding elements of the adjacent blades so as to allow relative pivoting about the axis common to the two cooperating elements. When the curtain is closed, its front face is substantially planar, and the longitudinal front edges of two adjacent blades are only separated by a narrow slot.

Les lames de ces fermetures à rideau sont relativement minces et leurs sections présentent une faible inertie. Lorsqu'on augmente l'épaisseur des lames ou qu'on modifie la forme de leurs sections pour en augmenter l'inertie, on constate que le rayon d'enroulement du rideau s'en trouve sensiblement augmenté.The blades of these curtain closures are relatively thin and their sections have low inertia. When the thickness of the slats is increased or the shape of their sections is modified to increase the inertia, it is found that the rolling radius of the curtain is significantly increased.

On connaît du document EP-A-0 428 844 une fermeture à rideau comportant des lames coextrudées avec des joints souples d'articulation portant à une extrémité une nervure en forme de champignon et, à l'autre extrémité, une ouverture formant rainure en vue d'une fixation rigide par encliquetage ou par coulissement.Document EP-A-0 428 844 discloses a curtain closure comprising coextruded blades with flexible joint joints carrying at one end a mushroom-shaped rib and, at the other end, an opening forming a groove in view rigid fixing by snap-fastening or sliding.

Ce document décrit une lame profilée pour fermeture à rideau, réalisée par coextrusion d'une bande en matériau souple coextrudé avec une section sensiblement trapézoïdale en matériau rigide et un jonc en matériau également rigide, ladite bande en matériau souple étant située sur la face du rideau à réaliser qui est inaccessible de l'extérieur.This document describes a profiled blade for closing curtain, produced by coextrusion of a strip of flexible material coextruded with a substantially trapezoidal section of rigid material and a rod of also rigid material, said strip of flexible material being located on the face of the curtain to be produced which is inaccessible from the outside.

On connaît également du document EP-A-0 558 390 une lame profilée pour fermeture à rideau. La section de la lame présente un logement et un jonc relié par une bande en matériau souple à l'angle de la petite base et d'un côté adjacent de la lame. La présence du jonc à l'angle de la petite base et du deuxième côté engendre des forces de frottements importantes. Dans cette structure, le jonc ne pivote pas relativement au logement.EP-A-0 558 390 also discloses a profiled blade for curtain closure. The blade section has a housing and a rod connected by a strip of flexible material at the corner of the small base and on an adjacent side of the blade. The presence of the rod at the angle of the small base and the second side generates significant friction forces. In this structure, the rod does not pivot relative to the housing.

Un premier but de la présente invention est de proposer une lame profilée de fermeture à rideau qui pallie les limites ou inconvénients de celles rencontrées dans l'état de la technique.A first object of the present invention is to provide a profiled curtain closure blade which overcomes the limits or drawbacks of those encountered in the prior art.

Plus précisément, de proposer des lames du type dont la structure permet le positionnement sélectif et aisé d'un outil de serrage ou de pincement relatif ou réciproque des moyens d'association des lames entre elles sans que cet outil ne dérape ou soit entravé par la lame. Un tel outil de serrage est destiné - grâce au pincement ou à la déformation locale des moyens d'association des lames entre elles qu'il permet- de bloquer les lames les unes par rapport aux autres en coulissement relatif longitudinal.A third object of the invention is to provide an articulated closing curtain comprising profiled blades of the type in which the male and female association members are intended not to pivot relative to one another, the pivoting being provided by a flexible and substantially inextensible band.

En référence à la figure 1, une lame profilée 1 pour fermeture à rideau selon l'invention comporte au moins une section droite transversale 2, de forme générale trapézoïdale ou pseudo-trapézoïdale, creuse, en matériau présentant une certaine rigidité pour être autoportant, par exemple en matière plastique du type polychlorure de vinyle.With reference to FIG. 1, a profiled blade 1 for curtain closure according to the invention comprises at least one cross-section 2, of general trapezoidal or pseudo-trapezoidal shape, hollow, made of a material having a certain rigidity to be self-supporting, by example in plastic material of the polyvinyl chloride type.

La section 2 présente une grande base 3 qui, dans un rideau de fermeture incorporant la lame 1 est normalement visible ou tournée vers l'extérieur, reliée à une petite base 4 opposée à et en regard de la grande base 3, normalement invisible ou tournée vers l'intérieur, par une première et une deuxième parois de côté 5, 6. Les deux bases 3 et 4 sont de directions générales parallèles entre elles. La petite base 4 présente dans la réalisation représentée une courbure à convexité tournée vers l'intérieur de la lame 1 de manière à coulisser dans une glissière de guidage (non représentée) appropriée s'étendant transversalement par rapport à la lame 1 à son extrémité, sensiblement à l'endroit de sommets arrondis limitant la petite base 4 de part et d'autre en étant adjacents aux parois de côté 5, 6.Section 2 presents a large base 3 which, in a closing curtain incorporating the blade 1 is normally visible or turned outwards, connected to a small base 4 opposite to and opposite the large base 3, normally invisible or turned inward, by first and second side walls 5, 6. The two bases 3 and 4 are of general directions parallel to each other. The small base 4 has in the embodiment shown a curvature with convexity turned towards the inside of the blade 1 so as to slide in a suitable guide slide (not shown) extending transversely with respect to the blade 1 at its end, substantially at the point of rounded vertices limiting the small base 4 on either side by being adjacent to the side walls 5, 6.

Les deux parois de côté 5, 6 sont de directions générales inclinées l'une par rapport à l'autre.The two side walls 5, 6 are of general directions inclined with respect to each other.

La section 2 peut comporter également une ou plusieurs cloison intérieure de renforcement 16, disposée de manière à relier les deux bases 3 et 4.Section 2 can also include one or more internal reinforcement partition 16, arranged so as to connect the two bases 3 and 4.

La section 2 présente et forme essentiellement vers l'intérieur un logement 10, profilé, cylindrique, destiné à recevoir un jonc 15 complémentaire d'une lame adjacente de même type. Le logement 10 est situé à l'angle de la petite base 4 et de la première paroi de côté 5. Il incorpore les sommets arrondis de la petite base 4. Le logement 10 présente une ouverture 11, s'étendant longitudinalement, dirigée sensiblement parallèlement aux bases 3, 4 et débouchant dans la première paroi de côté 5.Section 2 presents and essentially forms inwardly a housing 10, profiled, cylindrical, intended to receive a rod 15 complementary to an adjacent blade of the same type. The housing 10 is located at the corner of the small base 4 and the first side wall 5. It incorporates the rounded tops of the small base 4. The housing 10 has an opening 11, extending longitudinally, directed substantially parallel at bases 3, 4 and opening into the first side wall 5.

La paroi du logement 10 est formée de deux zones ou tronçons 10a, 10b. Chacune d'elles est adjacente à l'ouverture 11 et, en section droite transversale, a sensiblement un profil en demi-cercle.The wall of the housing 10 is formed of two zones or sections 10a, 10b. Each of them is adjacent to the opening 11 and, in cross section, has a substantially semicircular profile.

Les deux zones ou tronçons 10a, 10b sont donc opposées l'une à l'autre par rapport à l'axe du logement 10. Elles viennent en prolongation l'une de l'autre.The two zones or sections 10a, 10b are therefore opposite one another with respect to the axis of the housing 10. They come in extension of one another.

Cette décomposition de la paroi du logement 10 en deux zones ou tronçons 10a, 10b est destinée seulement à une bonne compréhension. En effet, ces deux zones ou tronçons 10a, 10b ne sont pas formellement séparées l'une de l'autre hormis à l'endroit de l'ouverture 11.This decomposition of the wall of the housing 10 into two zones or sections 10a, 10b is intended only for a good understanding. In fact, these two zones or sections 10a, 10b are not formally separated from each other except at the location of the opening 11.

La première zone 10a comprend en premier lieu le sommet arrondi de la petite base 4 attenant à la seconde paroi de côté 5 et éventuellement la partie de petite base 4 attenante à ce sommet.The first zone 10a firstly comprises the rounded top of the small base 4 adjoining the second side wall 5 and possibly the portion of small base 4 adjoining this top.

Elle comprend en deuxième lieu, d'un côté, la partie de la paroi de côté 5 comprise entre la petite base 3 et l'ouverture 11.Secondly, it comprises, on one side, the part of the side wall 5 between the small base 3 and the opening 11.

Elle comprend en troisième lieu, du côté opposé, une paroi 24 arrondie, située à l'intérieur de la section 2 et s'étendant dans une direction sensiblement perpendiculaire à la petite base 4.Thirdly, it comprises, on the opposite side, a rounded wall 24, situated inside the section 2 and extending in a direction substantially perpendicular to the small base 4.

Ainsi, la paroi du logement 10 est tangente et pour partie commune à la petite base 4 notamment à son sommet d'extrémité.Thus, the wall of the housing 10 is tangent and partly common to the small base 4 in particular at its end top.

La deuxième zone 10b comprend en premier lieu et d'un côté la paroi 24. Elle comprend en deuxième lieu et du côté opposé, un raccordement 25 limitant l'ouverture 11, attenant à la paroi de côté 5 et s'étendant vers l'intérieur de la section 2 sensiblement parallèlement aux bases 3 et 4.The second zone 10b comprises firstly and on one side the wall 24. It comprises secondly and on the opposite side, a connection 25 limiting the opening 11, adjoining the side wall 5 and extending towards the inside of section 2 substantially parallel to bases 3 and 4.

La deuxième zone 10b comprend, en troisième lieu et entre la paroi 24 - en la prolongeant - et le raccordement 25 - par l'intermédiaire d'un angle 26 -, une paroi 27 située sensiblement en regard du sommet arrondi correspondant de la petite base 4.The second zone 10b comprises, thirdly and between the wall 24 - by extending it - and the connection 25 - via an angle 26 -, a wall 27 located substantially opposite the corresponding rounded apex of the small base 4.

Du fait de la configuration qui vient d'être décrite, il est possible d'avoir accès, à la première zone ou tronçon 10a, de l'extérieur de la lame, notamment à l'endroit du sommet de la petite base 4. Et, s'agissant de la seconde zone 10b, de l'intérieur de la lame, à l'endroit de la paroi 27. En effet, il existe entre la paroi 27 et la grande base 3 située en regard un espace 8 libre suffisamment grand. Du côté extérieur de la lame, l'espace 8 est limité par la paroi 5. De l'autre côté par la cloison 16 si elle est prévue, ou sinon par la paroi 6. La cloison 16 est écartée de la paroi du logement 10 et notamment de la paroi 24 pour ne pas encombrer l'espace 8 et donc ne pas pas entraver le mouvement d'un outil de montage logé partiellement dans cet espace 8. Il en est de même de la paroi 5 ainsi qu'il est décrit par la suite.Because of the configuration which has just been described, it is possible to have access, to the first zone or section 10a, from the outside of the blade, in particular at the location of the top of the small base 4. And , as regards the second zone 10b, from the inside of the blade, at the location of the wall 27. In fact, there exists between the wall 27 and the large base 3 located opposite a sufficiently large free space 8 . On the outside of the blade, the space 8 is limited by the wall 5. On the other side by the partition 16 if it is provided, or otherwise by the wall 6. The partition 16 is spaced from the wall of the housing 10 and in particular of the wall 24 so as not to clutter the space 8 and therefore not not hinder the movement of a mounting tool partially housed in this space 8. It is the same for the wall 5 as described below.

Sur la deuxième paroi de côté 6 est prévue, vers l'extérieur de la lame, une bande souple et substantiellement inextensible d'articulation 14 coextrudée avec le corps de la lame en matériau rigide et se terminant par un jonc 15. Ce dernier est également en matériau rigide, de préférence identique au matériau rigide dans lequel est formée la lame.On the second side wall 6 is provided, towards the outside of the blade, a flexible and substantially inextensible band of articulation 14 coextruded with the body of the blade of rigid material and ending in a rod 15. The latter is also in rigid material, preferably identical to the rigid material in which the blade is formed.

L'amorce de rattachement du jonc 15 à la paroi 6 et l'ouverture 11 sont situées dans un même plan P lequel est sensiblement parallèle aux et placé entre les plans moyens des bases 3 et 4, tout en étant plus proche du plan de la petite base 4 que de celui de la grande base 3 et en étant légèrement décalé par rapport au plan moyen de la petite base 4. Cette structure est non seulement positive pour la fonction d'articulation recherchée mais également favorable - ou du moins non gênante - pour le pincement du logement 10 décrit par la suite.The start of attachment of the rod 15 to the wall 6 and the opening 11 are located in the same plane P which is substantially parallel to and placed between the mean planes of the bases 3 and 4, while being closer to the plane of the small base 4 than that of large base 3 and being slightly offset from the mean plane of small base 4. This structure is not only positive for the desired articulation function but also favorable - or at least not bothersome - for pinching the housing 10 described below.

La première paroi de côté 5 présente une nervure 12 en saillie vers l'extérieur de la lame, tandis que la deuxième paroi de côté 6 présente une rainure 13 en creux, de forme complémentaire à celle de la nervure 12.The first side wall 5 has a rib 12 projecting towards the outside of the blade, while the second side wall 6 has a hollow groove 13, of shape complementary to that of the rib 12.

Les nervure 12 et saillie 13 sont situées à proximité de la grande base 3.The rib 12 and projection 13 are located near the large base 3.

Cette disposition de la nervure 12, combinée à l'inclinaison de la paroi de côté 5 résultant de la forme trapézoïdale donnée à la lame permet de ne pas encombrer ou restreindre l'espace 8. A cet effet la nervure 12 est interposée entre un segment de paroi 7a, court, attenant et sensiblement perpendiculaire à la grande base 3 et un segment 7b attenant à l'ouverture 11. Le segment 7b est incliné sur la petite base 4 avec un angle obtus. Ainsi, le logement 8 comporte vers la paroi de côté 5 une sorte d'extension vers l'extérieur grâce à la nervure 12 et à l'inclinaison de la paroi.This arrangement of the rib 12, combined with the inclination of the side wall 5 resulting from the trapezoidal shape given to the blade makes it possible not to encumber or restrict the space 8. For this purpose the rib 12 is interposed between a wall segment 7a, short, adjoining and substantially perpendicular to the large base 3 and a segment 7b adjoining the opening 11. The segment 7b is inclined on the small base 4 with an obtuse angle. Thus, the housing 8 has towards the side wall 5 a kind of extension towards the outside thanks to the rib 12 and the inclination of the wall.

La nervure 12 d'une première lame est destinée à coopérer avec et s'adapter dans une rainure 13 d'une seconde lame adjacente, lorsque le jonc 15 de la seconde lame est logé dans le logement 10 de la première et que les deux lames ont leur bases respectives 3, 4 sensiblement coplanaires ce qui correspond à l'état fermé d'un rideau réalisé à partir de ces lames.The rib 12 of a first blade is intended to cooperate with and fit into a groove 13 of a second adjacent blade, when the rod 15 of the second blade is housed in the housing 10 of the first and that the two blades have their respective bases 3, 4 substantially coplanar which corresponds to the closed state of a curtain made from these blades.

La coopération des nervures et saillies 12, 13 des lames successives empêche l'insertion, depuis le côté situé vers les bases 3 d'un instrument tranchant susceptible de découper ou rompre la bande 14.The cooperation of the ribs and projections 12, 13 of the successive blades prevents the insertion, from the side situated towards the bases 3, of a cutting instrument capable of cutting or breaking the strip 14.

Les sections du jonc 15 et du logement 10 sont de formes transversales complémentaires et présentent des dimensions respectives déterminées avec un jeu suffisant pour qu'au montage du rideau de fermeture, le jonc 15 puisse être coulissé avec suffisamment de liberté dans le logement 10 de façon à permettre l'assemblage du rideau en position inclinée sensiblement en forme de parallélogramme puis son redressement pour le mettre en place sans risque de coincement dans une glissière de guidage.The sections of the rod 15 and of the housing 10 are of complementary transverse shapes and have respective dimensions determined with sufficient clearance so that, when the closing curtain is mounted, the rod 15 can be slid with sufficient freedom in the housing 10 so to allow the assembly of the curtain in an inclined position substantially in the form of a parallelogram and then its straightening to put it in place without risk of jamming in a guide slide.

Sur la figure 2, les chiffres de référence identiques à ceux de la figure 1 se rapportent à des éléments identiques ou similaires à ceux déjà décrits en relation avec la figure 1.In FIG. 2, the reference numbers identical to those in FIG. 1 refer to identical or similar elements to those already described in relation to FIG. 1.

Dans le mode de réalisation représenté à la figure 2, la lame la selon l'invention est formée par assemblage d'au moins deux sections trapézoïdales 2a, 2b réunies l'une à l'autre par une bande souple mais inextensible d'articulation 14a coextrudée avec le matériau rigide des deux sections trapézoïdales.In the embodiment shown in Figure 2, the blade according to the invention is formed by assembling at least two trapezoidal sections 2 a, 2 b joined to each other by a flexible inextensible strip but of joint 14 has coextruded with the rigid material of the two trapezoidal sections.

Chacune des sections 2a, 2b dérive de la section 2 décrite précédemment.Each of sections 2a, 2b derives from section 2 described above.

La section 2a comprend, comme la section 2, un logement 10 et, à l'opposé la bande 14a équivalente à la bande 14 de la section 2. Toutefois, la bande 14a est dépourvue d'un jonc tel que 15. Au lieu et place se trouve la section 2b. Cette dernière est donc dépourvue de logement 10.Section 2a includes, like section 2, a housing 10 and, on the other hand, band 14 a equivalent to band 14 of section 2. However, band 14a does not have a ring such as 15. Instead and place is section 2b. The latter is therefore devoid of housing 10.

La section 2b comporte, à l'opposé de la bande 14a, une bande 14 et un jonc 15, comme la section 2. Les deux parois de côté en regard des deux sections, auxquelles sont fixées la bande 14a, sont pourvues de nervure 12 et saillie 13 comme décrit précédemment. Ces nervure et saillie 13 peuvent être dirigées dans le même sens que décrit précédemment en relation avec la figure 1 et la lame 2, ou dans le sens opposé. La coopération de la nervure 12 dans la rainure 13 de ces deux parois de côté en regard empêche l'insertion depuis le côté situé vers la base 3 d'un instrument tranchant susceptible de découper ou rompre la bande souple d'articulation 14a.The section 2b comprises, opposite the strip 14a, a strip 14 and a rod 15, like section 2. The two side walls facing the two sections, to which the strip 14a are fixed, are provided with rib 12 and projection 13 as described above. These rib and projection 13 can be directed in the same direction as described above in relation to Figure 1 and the blade 2, or in the opposite direction. The cooperation of the rib 12 in the groove 13 of these two opposite side walls prevents the insertion from the side located towards the base 3 of a cutting instrument capable of cutting or breaking the flexible band of articulation 14a.

Après le montage du rideau selon l'invention, il est prévu de faire subir au logement 10 de une ou plusieurs lames 1 ou 1a, et généralement à tous les logements 10, une déformation mécanique, par pincement avec un outil 28 prévu à cet effet (figures 5 et 7). Cette déformation mécanique vise à bloquer les lames à coulissement axial relatif l'une par rapport à l'autre. On peut voir sur la figure 5 que la déformation mécanique subie par le logement 10 a pour effet de déformer essentiellement les zones 10a, 10b d'une première lame ainsi que le jonc 15 d'une lame adjacente engagé dans ladite première lame. Le jonc 15 ainsi coincé entre les zones 10a, 10b du logement 10 n'est plus susceptible de coulisser axialement relativement au logement 10.After mounting the curtain according to the invention, it is provided to subject the housing 10 one or more blades 1 or 1a, and generally to all the housings 10, mechanical deformation, by pinching with a tool 28 provided for this purpose (Figures 5 and 7). This mechanical deformation aims to block the blades with axial sliding relative to one another. It can be seen in FIG. 5 that the mechanical deformation undergone by the housing 10 has the effect of essentially deforming the zones 10a, 10b of a first blade as well as the rod 15 of an adjacent blade engaged in said first blade. The rod 15 thus wedged between the zones 10a, 10b of the housing 10 is no longer capable of sliding axially relative to the housing 10.

La géométrie de la lame décrite favorise la mise en oeuvre de l'outil 28.The geometry of the blade described favors the use of tool 28.

En effet et tout d'abord, il existe une amplitude de positionnement de l'outil 28 importante. Cette amplitude est illustrée, sur la figure 7 par les lignes en tiretés A et B qui correspondent sensiblement aux plans extrêmes de contact des mors interne 29 et externe 30 de l'outil 28 avec les zones ou tronçons 10b, 10a, respectivement.Indeed and first of all, there is a large positioning amplitude of the tool 28. This amplitude is illustrated in FIG. 7 by the dashed lines A and B which correspond substantially to the extreme planes of contact of the internal jaws 29 and external jaws 30 of the tool 28 with the zones or sections 10b, 10a, respectively.

Il en résulte que la mise en place des mors 29, 30 est facilitée ou, du moins, moins critique surtout lorsque celle-ci est manuelle.As a result, the positioning of the jaws 29, 30 is facilitated or, at least, less critical especially when the latter is manual.

En deuxième lieu, les mors 29, 30 viennent s'appliquer sur deux parties sensiblement diamétralement opposées des zones ou tronçons 10a, 10b. Ces parties sont libres de toute entrave. L'appui diamétral sur les zones ou tronçons 10a, 10b favorise la tenue des mors 29, 30 en évitant leur glissement sur la paroi du logement 10. Elle permet aussi un serrage efficace et donc une déformation convenable de cette paroi laquelle permet tout à la fois un blocage à coulissement axial satisfaisant, une grande propreté à l'endroit de la déformation et une déformation juste localisée à ce qui est strictement nécessaire. En particulier, la paroi de côté 5 n'est pas affectée par la déformation.Secondly, the jaws 29, 30 are applied to two substantially diametrically opposite parts of the zones or sections 10a, 10b. These parts are free of any hindrance. The diametral support on the zones or sections 10a, 10b promotes the holding of the jaws 29, 30 by preventing their sliding on the wall of the housing 10. It also allows effective clamping and therefore a suitable deformation of this wall which allows at the same time a blocking with satisfactory axial sliding, great cleanliness at the location of the deformation and a deformation just localized to what is strictly necessary. In particular, the side wall 5 is not affected by the deformation.

En troisième lieu, l'espace 8 permet tout à la fois la mise en place et le positionnement sur une certaine amplitude, en toutes directions, du mors 29, notamment sans risques d'affecter la grande base 3 ou la paroi de côté 5. Cela permet également l'ouverture de l'outil 28 ainsi que sa fermeture et favorise la pénétration du mors 29 dans la lame.Thirdly, the space 8 allows both the positioning and the positioning over a certain amplitude, in all directions, of the jaw 29, in particular without risk of affecting the large base 3 or the side wall 5. This also allows the opening of the tool 28 as well as its closing and promotes the penetration of the jaw 29 in the blade.

L'invention concerne également un rideau de fermeture articulé comportant un assemblage de lames 1, la telles qu'elles viennent d'être décrites. Un tel rideau, destiné plus particulièrement à fermer des armoires notamment de bureau, se présente tel que représenté en figure 6. Il comprend un assemblage de lames profilées 1, la et le cas échéant d'au moins une lame 17 formant poignée permettant de faciliter la manipulation du rideau lors de son ouverture ou de sa fermeture. Un organe de préhension 22 est également prévu à l'une des extrémités libres transversale du rideau correspondant à une lame d'extrémité.The invention also relates to an articulated closing curtain comprising an assembly of blades 1, such as they have just been described. Such a curtain, intended more particularly for closing cupboards, especially office cabinets, is presented as shown in FIG. 6. It comprises an assembly of profiled blades 1, the and, if necessary, at least one blade 17 forming a handle making it possible to facilitate handling the curtain when opening or closing it. A gripping member 22 is also provided at one of the transverse free ends of the curtain corresponding to an end blade.

Le rideau de fermeture est placé avec les lames disposées avec leurs axes longitudinaux soit horizontal (cas de figure) soit vertical (non représenté).The closing curtain is placed with the blades arranged with their longitudinal axes either horizontal (case) or vertical (not shown).

En vue de son fonctionnement, le rideau est enroulé ou déroulé sur un cylindre d'enroulement 23 via un cylindre-relais 24.For operation, the curtain is rolled up or unwound on a winding cylinder 23 via a relay cylinder 24.

Il est également prévu des glissières (non représentées) de guidage et de coulissement des parties extrêmes libres des lames.There are also provided slides (not shown) for guiding and sliding the free end portions of the blades.

La lame 17 formant poignée a une structure permettant son assemblage avec une lame 1, 1a profilée adjacente, sa mise en place sans risque de coincement dans une glissière de guidage, et, enfin, son blocage à coulissement axial d'une manière sensiblement analogue à mais adaptée de celle des lames 1 et 1a.The blade 17 forming a handle has a structure allowing it to be assembled with a blade 1, 1 has an adjacent profile, its positioning without risk of jamming in a guide slide, and, finally, its axial sliding blocking in a substantially similar manner. to but adapted from that of blades 1 and 1 a .

A cet effet, la lame 17 formant poignée forme une section droite transversale 2c s'inscrivant dans un trapèze ou pseudo-trapèze présentant une partie supérieure 21 reliée à une petite base 4 par une première paroi de côté 5a et une deuxième paroi de côté 6a. La section 2c présente un logement 10 cylindrique destiné à recevoir un jonc 15 d'une lame profilée 1, la adjacente. Le logement 10 est situé à l'angle de la petite base 4 et de la première paroi de côté 5a et présente une ouverture 11 dirigée sensiblement parallèlement à la petite base 4a et débouchant vers la première paroi de côté 5a.To this end, the blade 17 forming a handle forms a transverse cross section 2 c forming part of a trapezoid or pseudo-trapezium having an upper part 21 connected to a small base 4 by a first side wall 5 a and a second wall of side 6 a . Section 2 c presents a cylindrical housing 10 intended to receive a rod 15 of a profiled blade 1, the adjacent one. The housing 10 is located at the corner of the small base 4 and the first side wall 5a and has an opening 11 directed substantially parallel to the small base 4a and opening toward the first side wall 5a.

On retrouve donc substantiellement la même configuration que la section trapézoïdale 2, 2a d'une lame profilée 1, 1a. Toutefois, la lame 17 formant poignée présente la particularité de comporter, au lieu de la grande base 3, une partie supérieure 21 ayant en section droite transversale une forme de cavité ou de gorge en U ou pseudo-U qui permet le positionnement de 1a ou des mains d'un utilisateur du rideau.Therefore include substantially the same configuration as the trapezoidal section 2, 2 has a profiled blade 1, 1 a. However, the blade 17 forming a handle has the particularity of comprising, instead of the large base 3, an upper part 21 having a cross-section in the form of a U-shaped or pseudo-U-shaped cavity or groove which allows the positioning of 1a or from the hands of a curtain user.

La partie supérieure 21 comporte tout d'abord une âme 31. Celle-ci s'étend sensiblement parallèlement à la petite base 4. Elle a également pour particularité d'inclure la partie de la paroi du logement 10 située sensiblement diamétralement à l'opposé du sommet arrondi de la petite base 4. La partie supérieure 21 comporte, ensuite, de part et d'autre de l'âme 31, une première et une deuxième branches 20, 18. Ces deux branches 18, 20 s'étendent dans une direction sensiblement perpendiculaire à l'âme et vers l'extérieur de la lame 17.The upper part 21 firstly comprises a core 31. This extends substantially parallel to the small base 4. It also has the particularity of including the part of the wall of the housing 10 located substantially diametrically opposite from the rounded top of the small base 4. The upper part 21 then comprises, on either side of the core 31, a first and a second branch 20, 18. These two branches 18, 20 extend in a direction substantially perpendicular to the core and towards the outside of the blade 17.

La première branche 20 rejoint la première paroi de côté 5a par l'intermédiaire d'un tronçon 32 de direction générale sensiblement parallèle à la grande base 3. Ce tronçon 32 est destiné à prolonger la grande base 3 de la lame adjacente à la poignée 17 lorsque le rideau est fermé. Sur la paroi 5a est prévue une nervure en saillie 12.The first branch 20 joins the first side wall 5a via a section 32 of general direction substantially parallel to the large base 3. This section 32 is intended to extend the large base 3 of the blade adjacent to the handle 17 when the curtain is closed. On the wall 5a is provided a projecting rib 12.

La seconde branche 18 rejoint la seconde paroi de côté 6a par l'intermédiaire d'un tronçon sensiblement coplanaire mais écarté du tronçon 32. Ce tronçon comporte un retour 18a sensiblement perpendiculaire et dirigé vers la petite base 4, qui définit avec la branche 18 et le tronçon une rainure en creux correspondant à celle 13 déjà décrite.The second branch 18 joins the second side wall 6a by means of a substantially coplanar section but spaced from the section 32. This section has a return 18a substantially perpendicular and directed towards the small base 4, which defines with the branch 18 and the section a hollow groove corresponding to that 13 already described.

On notera que les tronçons 32, occupent, dans la lame 17 la même position relative que les grandes bases 3 dans les lames 1, 1a.Note that the sections 32, in the blade 17 occupy the same relative position as the large bases 3 in the blades 1, 1a.

Avec la lame 17 qui vient d'être décrite, il existe deux parties accessibles de l'extérieur de la lame. L'une comprend, comme antérieurement, une partie de la petite base 4. L'autre comprend une partie de l'âme de la partie supérieure 32 à savoir celle adjacente à la branche 20. S'agissant de la lame 17, il n'y a donc pas d'espace libre fermé correspondant à l'espace libre 8 décrit précédemment, mais un espace libre ouvert formé par la cavité ou gorge de la partie supérieure 21.With the blade 17 which has just been described, there are two parts accessible from the outside of the blade. One includes, as before, part of the small base 4. The other comprises a part of the core of the upper part 32, namely that adjacent to the branch 20. As regards the blade 17, there is therefore no closed free space corresponding to the free space 8 described above, but an open free space formed by the cavity or groove in the upper part 21.

Selon un autre aspect, l'invention concerne un procédé de réalisation d'un rideau de fermeture dans lequel on fait coopérer, par coulissement axial relatif, le jonc 15 d'une lame avec le logement 10 d'une lame adjacente. Après coopération des lames on déforme par pincement la paroi des logements 10 pour assurer le blocage en coulissement axial des lames les unes par rapport aux autres et, à cet effet, on met en oeuvre un outil 28 dont les mors 29, 30 agissent sur les deux parties accessibles de la paroi de logement 10 situées sensiblement diamétralement opposées et précédemment décrites.According to another aspect, the invention relates to a method for producing a closing curtain in which the rod 15 of a blade is made to cooperate, by relative axial sliding, with the housing 10 of an adjacent blade. After cooperation of the blades, the wall of the housings 10 is deformed by pinching to ensure the axial sliding locking of the blades with respect to each other and, for this purpose, a tool 28 is used, the jaws 29, 30 of which act on the two accessible parts of the housing wall 10 located substantially diametrically opposite and previously described.
