Description

La présente invention est relative à un dispositif avec un rideau pouvant être enroulé et déroulé entre une position de fermeture et d'ouverture pour permettre de fermer ou d'ouvrir une baie ou autre ouverture, le rideau présentant à proximité de ses bords latéraux deux courroies crantées comprenant ainsi une succession de dents, ces deux courroies étant situées en regard l'une de l'autre pour que, lors de l'enroulement du rideau, les deux courroies puissent s'engrener l'une avec l'autre.The present invention relates to a device with a curtain that can be wound and unwound between a closed position and opening to allow closing or opening a bay or other opening, the curtain having near its side edges two belts notched thus comprising a succession of teeth, these two belts being located facing each other so that, during the winding of the curtain, the two belts can mesh with each other.

Ce dispositif peut être destiné à la fermeture d'une baie de porte ou de fenêtre, du volume de chargement d'un véhicule, tels que d'un camion ou d'un bateau, au recouvrement d'une piscine etc. On connaît les documents WO 03/048497 A et DE 196 36 176 A1 .This device can be intended for closing a door or window bay, the loading volume of a vehicle, such as a truck or a boat, the recovery of a pool etc. We know the documents WO 03/048497 A and DE 196 36 176 A1 .

Lors de l'enroulement ou du déroulement du rideau des dispositifs connus de ce genre vers sa position d'ouverture ou de fermeture le risque existe que les bords latéraux ne soient pas correctement enroulés ou déroulés, mais subissent un glissement latéral ayant généralement comme conséquence le désengrènement des courroies.When winding or unwinding the curtain of known devices of this kind to its open or closed position the risk exists that the side edges are not properly wound or unwound, but undergo a lateral sliding generally resulting in the disengaging the belts.

Le but essentiel de la présente invention est d'éviter ce problème et ceci d'une manière très simple et très efficace.The essential object of the present invention is to avoid this problem and this in a very simple and very effective way.

A cet effet une face latérale des dents qui s'étend suivant la direction longitudinale du bord latéral correspondant d'au moins une des courroies prévue sur une face du rideau prend appui contre un élément de support lorsque le rideau est enroulé, cet élément de support étant prévu sur l'autre face du rideau.For this purpose a lateral face of the teeth which extends in the longitudinal direction of the corresponding lateral edge of at least one of the belts provided on one side of the curtain bears against a support element when the curtain is wound, this support element. being provided on the other side of the curtain.

De préférence, le rideau présente à proximité de chacun de ses bords latéraux un rebord parallèle à ces derniers.Preferably, the curtain has close to each of its lateral edges a flange parallel to them.

Avantageusement, le rebord est prévu sur la courroie située du côté de la face intérieure du rideau dans sa position enroulée.Advantageously, the rim is provided on the belt located on the side of the inner face of the curtain in its wound position.

Suivant une forme de réalisation particulière de l'invention, le rebord s'étend sensiblement jusqu'à la face supérieure de la tête des dents de la courroie crantée.According to a particular embodiment of the invention, the flange extends substantially to the upper face of the tooth head of the toothed belt.

Suivant une autre forme de réalisation de l'invention, le rebord est prévu du côté des dents opposé à celui orienté vers le bord latéral du rideau.According to another embodiment of the invention, the flange is provided on the side of the teeth opposite that facing the side edge of the curtain.

D'une façon générale, la présente invention concerne un dispositif à rideau pouvant s'enrouler entre une position de fermeture et une position d'ouverture notamment pour permettre de fermer ou d'ouvrir une baie ou autre ouverture. Le rideau présente à proximité de ses bords latéraux deux courroies crantées comprenant ainsi une succession de dents s'étendant suivant leur direction longitudinale. Ces deux courroies sont situées de part et d'autre du rideau en regard l'une de l'autre pour que, lors de l'enroulement du rideau, elles puissent s'engrener l'une dans l'autre.In general, the present invention relates to a curtain device that can be wound between a closed position and an open position in particular to allow closing or opening a bay or other opening. The curtain has, near its lateral edges, two notched belts thus comprising a succession of teeth extending in their longitudinal direction. These two belts are located on either side of the curtain facing each other so that, during the winding of the curtain, they can mesh one into the other.

Ce dispositif est caractérisé par le fait que les dents d'au moins une des courroies crantées, prévue sur une face du rideau, prennent appui contre un élément de support qui est prévu sur l'autre face du rideau à proximité du bord latéral correspondant lorsque le rideau est enroulé.This device is characterized in that the teeth of at least one of the toothed belts, provided on one side of the curtain, bear against a support element which is provided on the other side of the curtain near the corresponding lateral edge when the curtain is rolled up.

De préférence, le rideau présente, à proximité de chacun de ses bords latéraux un élément de support qui est formé par un rebord s'étendant parallèlement par rapport à ces bords latéraux. Il s'agit, plus particulièrement, d'un rebord prévu sur la courroie située du côté de la face intérieure du rideau. Par la face intérieure du rideau est entendu la face du rideau qui est dirigée vers l'axe de courbure du rideau lorsque celui-ci est enroulé.Preferably, the curtain has, near each of its lateral edges, a support member which is formed by a flange extending parallel to these side edges. This is, more particularly, a rim provided on the belt located on the side of the inner face of the curtain. By the inner face of the curtain is meant the face of the curtain which is directed towards the axis of curvature of the curtain when it is wound.

La figure 1 montre schématiquement en plan une portion d'une courroie crantée 1 fixée sur une des faces d'un rideau 2 à proximité d'un bord latéral 3 de ce dernier. Cette courroie 1 comprend une succession de dents 5 s'étendant perpendiculairement à son axe longitudinal, c.-à-d. les bases des faces successives frontales 21 des dents 5 dans la direction longitudinale de la courroie 1 forment un angle β avec cet axe de 90°.The figure 1 shows schematically in plan a portion of a toothed belt 1 fixed on one side of a curtain 2 near a side edge 3 of the latter. This belt 1 comprises a succession of teeth 5 extending perpendicularly to its longitudinal axis, i.e. the bases of the successive front faces 21 of the teeth 5 in the longitudinal direction of the belt 1 form an angle β with this axis of 90 °.

Le côté de la courroie 1 orienté vers le bord latéral 3 du rideau 2 est situé sur la face intérieure de ce dernier, lorsque celui-ci est enroulé, et présente un rebord 4 s'étendant le long de ce bord 3 et jusqu'au niveau de la face supérieure des dents 5. La face latérale du rebord 4 qui est adjacente aux dents 5 est fixée à ces dents.The side of the belt 1 facing the lateral edge 3 of the curtain 2 is located on the inner face of the latter, when the latter is wound, and presents a flange 4 extending along this edge 3 and up to the level of the upper face of the teeth 5. The side face of the flange 4 which is adjacent to the teeth 5 is fixed to these teeth.

La présence du rebord 4 permet d'éviter le glissement transversal d'une courroie par rapport à celle avec laquelle elle s'engrène. De plus, la présence d'un rebord le long de chacun des bords latéraux 3 sur l'une des faces du rideau 2 permet de tendre ce dernier entre les courroies correspondantes, qui sont fixées aux bords latéraux opposés 3, lors de l'enroulement du rideau 2.The presence of the flange 4 avoids the transverse sliding of a belt relative to that with which it meshes. In addition, the presence of a rim along each of the lateral edges 3 on one of the faces of the curtain 2 makes it possible to tension the latter between the corresponding belts, which are attached to the opposite lateral edges 3, during the winding of the curtain 2.

La figure 2 montre plus en détail une forme de réalisation de l'invention comprenant de part et d'autre du rideau 2, à proximité du bord latéral 3, deux courroies crantées 1 et 6 dont la courroie 1 présente un rebord 4. La section des dents des courroies crantées 1 et 6 dans la direction longitudinale des courroies et dans un plan sensiblement transversal par rapport au plan du rideau 2, présentent l'allure d'un parallélogramme.The figure 2 shows in more detail an embodiment of the invention comprising on both sides of the curtain 2, near the side edge 3, two toothed belts 1 and 6, the belt 1 has a flange 4. The section of the teeth of the notched belts 1 and 6 in the longitudinal direction of the belts and in a plane substantially transverse to the plane of the curtain 2, have the appearance of a parallelogram.

Comme déjà mentionné ci-dessus en rapport avec la figure 1 et comme montré clairement sur la figure 2, les dents 5 de la courroie 1 située du côté intérieure du rideau 2 s'étendent jusqu'au même niveau que le rebord 4 de sorte que la surface supérieure des dents 5 s'étend dans le même plan que la surface supérieure du rebord 4. De plus, ces dents 5, et donc la courroie 1, forment un tout avec ce rebord 4.As already mentioned above in relation to the figure 1 and as clearly shown on the figure 2 , the teeth 5 of the belt 1 located on the inner side of the curtain 2 extend to the same level as the flange 4 so that the upper surface of the teeth 5 extends in the same plane as the upper surface of the flange 4 In addition, these teeth 5, and therefore the belt 1, form a whole with this rim 4.

Par ailleurs, une bande flexible 7 est avantageusement prévue entre le rideau 2 et la courroie 1. Cette bande 7 est sensiblement incompressible dans le sens de sa longueur d'une manière telle à permettre d'exercer une force de poussée sur les bords latéraux 3 du rideau 2 suivant leur direction longitudinale pour déplacer ce dernier de sa position d'ouverture vers sa position de fermeture.Furthermore, a flexible strip 7 is advantageously provided between the curtain 2 and the belt 1. This strip 7 is substantially incompressible in the direction of its length in such a way as to allow to exert a thrust force on the lateral edges 3 curtain 2 in their longitudinal direction to move the latter from its open position to its closed position.

Lorsque l'ensemble des courroies 1 et 6 est suffisamment incompressible pour permettre d'y exercer une force de poussée dans leur direction longitudinale, il est évidement qu'il n'est pas nécessaire de prévoir ladite bande flexible 7. Des courroies qui conviennent sont par exemple réalisées en polyuréthanne.When all the belts 1 and 6 are sufficiently incompressible to allow to exert a thrust force in their longitudinal direction, it is obviously not necessary to provide said flexible strip 7. Suitable belts are for example made of polyurethane.

Comme montré aux figures 3 et 4, le rideau présente sur sa face opposée à celle où est prévue la courroie crantée 1 avec le rebord 4, un évidement correspondant 10 dans lequel ce rebord 4 peut être engagé lors de l'enroulement du rideau 2.As shown in Figures 3 and 4 , the curtain has on its face opposite that which is provided the toothed belt 1 with the flange 4, a corresponding recess 10 in which the flange 4 can be engaged during the winding of the curtain 2.

Ces figures sont une coupe transversale d'une partie du rideau 2 enroulé sur un tambour 12. Il s'agit d'une coupe suivant un plan passant par l'axe 9 du tambour 12.These figures are a cross section of a portion of the curtain 2 wound on a drum 12. This is a section along a plane passing through the axis 9 of the drum 12.

On y montre la façon dont les dents 5 et 8 des deux courroies 1 et 6 s'engrènent dans l'état enroulé du rideau 2. Le rebord 4 s'étend latéralement par rapport aux dents 5 de la courroie 1.It shows how the teeth 5 and 8 of the two belts 1 and 6 mesh in the wound state of the curtain 2. The flange 4 extends laterally with respect to the teeth 5 of the belt 1.

Dans la figure 3, l'évidement 10 est obtenu en faisant dépasser la courroie 1 par rapport au bord latéral 3 du rideau d'une distance correspondant à la largeur du rebord 4. Ainsi, lors de l'enroulement du rideau 2, ce rebord 4 s'engage dans cet évidement 10 pendant que les courroies 1 et 6 s'engrènent l'une dans l'autre. De cette manière, le rebord 4 prend appui contre les dents 8 de la courroie 6.In the figure 3 the recess 10 is obtained by passing the belt 1 with respect to the lateral edge 3 of the curtain by a distance corresponding to the width of the flange 4. Thus, during the winding of the curtain 2, this flange 4 engages in this recess 10 while the belts 1 and 6 mesh with one another. In this way, the flange 4 bears against the teeth 8 of the belt 6.

Etant donné qu'une telle courroie 1 avec un rebord 4 est prévue sur les deux bords latéraux du rideau 2, une spire qui est formée lors de l'enroulement du rideau 2 est fixée latéralement par rapport à la spire formée précédemment.Since such a belt 1 with a flange 4 is provided on both side edges of the curtain 2, a turn which is formed during winding of the curtain 2 is fixed laterally with respect to the previously formed turn.

La forme de réalisation représentée à la figure 4 se distingue par rapport à celle faisant l'objet des figures 1 à 3 par le fait que l'évidement 10 est pratiquée latéralement dans les dents 8 de la courroie 6 et présente la même largeur que le rebord 4.The embodiment shown in figure 4 distinguishes itself from the one subject to the Figures 1 to 3 in that the recess 10 is made laterally in the teeth 8 of the belt 6 and has the same width as the rim 4.

Le rebord 4 s'appuie latéralement contre les dents 8 de la courroie 6, ce qui empêche tout glissement latéral des courroies 1 et 6 l'une par rapport à l'autre.The flange 4 is supported laterally against the teeth 8 of the belt 6, which prevents lateral slippage of the belts 1 and 6 relative to each other.

Le rideau 2 est enroulé autour d'un tambour 12 dans lequel une rainure 11 est prévue s'étendant sur le pourtour du tambour 12. Lors de l'enroulement du rideau 2 pour former une première spire, les dents 5 de la courroie 1 avec le rebord 4 s'engagent dans cette rainure 11.The curtain 2 is wrapped around a drum 12 in which a groove 11 is provided extending around the periphery of the drum 12. When winding the curtain 2 to form a first turn, the teeth 5 of the belt 1 with the rim 4 engage in this groove 11.

Dans la figure 5 on représente une section transversale d'un rideau 2 dont les bords latéraux sont guidés dans des glissières 13 montées de part et d'autre d'une baie 16 prévue dans une paroi 17. Ces glissières 13 comprennent un profilé ayant une section transversale en U dont les extrémités 15 des ailes 14 sont repliées l'une vers l'autre, de manière à maintenir ainsi ces bords latéraux et à permettre le passage du rideau 2 par une fente 19 ménagée entre ces extrémités 15.In the figure 5 there is shown a cross section of a curtain 2 whose lateral edges are guided in slides 13 mounted on either side of a bay 16 provided in a wall 17. These slides 13 comprise a section having a cross section U whose ends 15 of the wings 14 are folded towards each other, so as to maintain these side edges and to allow the passage of the curtain 2 by a slot 19 formed between these ends 15.

Les bords latéraux du rideau 2 comprennent une bande flexible 18 sur laquelle sont prévues des courroies dentées 1 et 6 déjà décrites ci-dessus. Cette bande flexible 18 est fixée sur toute sa longueur au corps du rideau 2.The lateral edges of the curtain 2 comprise a flexible band 18 on which there are provided toothed belts 1 and 6 already described above. This flexible band 18 is fixed along its entire length to the body of the curtain 2.

Ces courroies 1 et 6 sont maintenues dans la glissière 13 correspondante, de sorte que les faces latérales 22 des dents 8 de la courroie 6 et des dents 5 de la courroie 1 prennent appui contre lesdites extrémités 15. Celle-ci s'étendent parallèlement par rapport à ces faces latérales 22 de part et d'autre de la fente 13 à travers laquelle s'étend le rideau 2.These belts 1 and 6 are held in the corresponding slideway 13, so that the lateral faces 22 of the teeth 8 of the belt 6 and the teeth 5 of the belt 1 bear against said ends 15 which extend parallel to each other. relative to these lateral faces 22 on either side of the slot 13 through which the curtain 2 extends.

Dans une variante de la forme de réalisation faisant l'objet de la figure 5, le rebord 4 est prévu du côté de la courroie 6' opposé à celui orienté vers le bord latéral du rideau 2.In a variant of the embodiment subject of the figure 5 , the flange 4 is provided on the opposite side of the belt 6 'to that facing the side edge of the curtain 2.

Dans cette forme de réalisation, qui est représentée dans la figure 6, la courroie 6', qui présente le rebord 4, est prévue sur la face extérieure du rideau 2. Cette face extérieure est la face qui est opposée à la face intérieure qui est dirigée vers l'axe de courbure du rideau lorsque celui-ci est enroulé.In this embodiment, which is represented in the figure 6 , the belt 6 ', which has the rim 4, is provided on the outer face of the curtain 2. This outer face is the face which is opposite to the inner face which is directed towards the axis of curvature of the curtain when the latter is rolled up.

La courroie 1', qui se situe au côté de la face intérieure du rideau 2, présente une base 20 ayant une certaine épaisseur. La largeur de cette base 20 correspond sensiblement à la largeur de l'ensemble de la courroie 6' et du rebord 4. Ainsi, la base 20 de cette courroie 1' prend appui contre l'extrémité correspondant 15 de la glissière 13.The belt 1 ', which is located at the side of the inner face of the curtain 2, has a base 20 having a certain thickness. The width of this base 20 corresponds substantially to the width of the assembly of the belt 6 'and the flange 4. Thus, the base 20 of this belt 1' bears against the corresponding end 15 of the slide 13.

Du côté de la face extérieure du rideau 2 et de l'autre côté de la fente 19, le rebord 4 prend appui contre l'extrémité correspondante 15 du profilé formant la glissière 13.On the side of the outer face of the curtain 2 and on the other side of the slot 19, the flange 4 bears against the corresponding end 15 of the profile forming the slide 13.

Ledit évidement 10 dans lequel le rebord 4 est logé lors de l'enroulement du rideau 2, se situe, par conséquent, au-dessus de ladite base 20 latéralement par rapport aux dents 5 de la courroie 1'.Said recess 10 in which the flange 4 is housed during the winding of the curtain 2, is therefore located above said base 20 laterally with respect to the teeth 5 of the belt 1 '.

Dans les figure 7 à 12, encore une autre forme de réalisation du rideau suivant l'invention est représentée. Dans cette forme de réalisation, sur chacune des faces du rideau à proximité des deux bords latéraux opposés 3 est fixée une courroie crantée 1 et 6. Lors de l'enroulement du rideau 2, les courroies 1 et 6 de chacune des bords latéraux 3 s'engrènent l'une avec l'autre.In the figure 7 to 12 yet another embodiment of the curtain according to the invention is shown. In this embodiment, on each of the sides of the curtain near the two opposite lateral edges 3 is fixed a toothed belt 1 and 6. During the winding of the curtain 2, the belts 1 and 6 of each of the lateral edges 3 s 'mesh with each other.

La courroie 1 est pourvue d'un rebord 4 formé par une succession de traverses 23 reliant les dents successives 5 de cette courroie 1 les unes aux autres dans leur partie médiane suivant la direction longitudinale des courroies. Les dents 8 de la courroie 6 prévue sur la face opposée du rideau 2 présentent des évidements correspondants 10 dans lesquels sont logés les traverses 23 du rebord 4 lorsque le rideau 2 est enroulé. Ainsi, les courroies 1 et 6 de chacun des bords latéraux 3 du rideau 2 sont fixées l'une à l'autre et ne peuvent pas glisser latéralement l'une par rapport à l'autre lorsque le rideau 2 est enroulé.The belt 1 is provided with a rim 4 formed by a succession of crosspieces 23 connecting the successive teeth 5 of this belt 1 to each other in their median part in the longitudinal direction of the belts. The teeth 8 of the belt 6 provided on the opposite face of the curtain 2 have corresponding recesses 10 in which are housed the crosspieces 23 of the flange 4 when the curtain 2 is wound. Thus, the belts 1 and 6 of each of the lateral edges 3 of the curtain 2 are fixed to one another and can not slide laterally relative to each other when the curtain 2 is wound.

Le tambour 12, sur lequel le rideau 2 est enroulé lors du déplacement du rideau 2 vers sa position d'ouverture, présente une nervure 24 sur son pourtour dont la section transversale correspond à la section de l'évidement 10 prévu dans les dents 8 de la courroie crantée 6. Ainsi, lors de l'enroulement du rideau 2 pour former une première spire, cette nervure 24 s'engage dans l'évidement 10 des dents 8.The drum 12, on which the curtain 2 is wound during the movement of the curtain 2 towards its open position, has a rib 24 on its periphery whose cross section corresponds to the section of the recess 10 provided in the teeth 8 of the toothed belt 6. Thus, during the winding of the curtain 2 to form a first turn, this rib 24 engages in the recess 10 of the teeth 8.

Cette dernière forme de réalisation du rideau, suivant l'invention, a comme avantage que les courroies 1 et 6 peuvent être enroulées d'une manière très régulière est stable indépendamment du type de rideau utilisé. Il n'est, par exemple, pas nécessaire que le rideau soit tendu entre ses bords latéraux pour obtenir un bon enroulement des bords latéraux du rideau. En plus, les courroies crantées et les bords latéraux pourvus de ces courroies présentent un plan de symétrie ce qui facilite leur fabrication et leur application. Lorsque les bords latéraux 3 avec les courroies 1 et 6 sont guidés par des glissières, comme représenté dans la figure 12, la surface de contact entre les courroies 1 et 6 et l'extrémité correspondant 15 de la glissière est sensiblement identique de part et d'autre du plan du rideau 2 ou de part et d'autre de la fente 19.This last embodiment of the curtain, according to the invention, has the advantage that the belts 1 and 6 can be wound in a very regular manner and is stable regardless of the type of curtain used. It is, for example, unnecessary for the curtain to be stretched between its side edges to obtain a good winding of the lateral edges of the curtain. In addition, the toothed belts and the side edges provided with these belts have a plane of symmetry which facilitates their manufacture and their application. When the side edges 3 with the belts 1 and 6 are guided by slides, as shown in FIG. figure 12 , the contact surface between the belts 1 and 6 and the corresponding end 15 of the slideway is substantially identical on both sides of the plane of the curtain 2 or on both sides of the slot 19.

Dans la figure 13 est représentée une autre forme de réalisation du dispositif, suivant l'invention, qui présente également les avantages des formes de réalisation précédentes. Dans cette forme de réalisation, le rideau 2 présente à chacun de ses bords latéraux opposés sur les faces opposées du rideau 2 une courroie crantée 1 et 6, comme déjà décrit ci-dessus pour les autres formes de réalisation de l'invention. Adjacent à ces courroies 1 et 6 est pourvu un élément de support en forme d'une courroie crantée supplémentaire 25, et respectivement 26, qui s'étend également suivant la direction longitudinale des bords latéraux 3 sur chacune des faces du rideau 2. Ces courroies supplémentaires 25 et 26 de chaque bord latéral 3 s'engrènent l'une avec l'autre lors de l'enroulement du rideau 2.In the figure 13 Another embodiment of the device according to the invention is shown which also has the advantages of the preceding embodiments. In this embodiment, the curtain 2 has at each of its opposite side edges on the opposite sides of the curtain 2 a toothed belt 1 and 6, as already described above for the other embodiments of the invention. Adjacent to these belts 1 and 6 is provided a support member in the form of an additional toothed belt 25, and 26 respectively, which also extends in the longitudinal direction of the lateral edges 3 on each of the faces of the curtain 2. These additional belts 25 and 26 of each lateral edge 3 mesh with each other during the winding of the curtain 2.

En plus, les dents 27 des courroies supplémentaires 25 et 26 sont décalées par rapport aux dents 5 et 8 des courroies précitées correspondantes 1 et 6 de sorte que les dents 5 et 8 de ces courroies 1 et 6 prennent appui contre les dents 27 des courroies 25 et 26 lors de l'enroulement du rideau. Ainsi, ces courroies supplémentaires 25 et 26 forment un rebord discontinu 4.In addition, the teeth 27 of the additional belts 25 and 26 are offset relative to the teeth 5 and 8 of the aforementioned corresponding belts 1 and 6 so that the teeth 5 and 8 of these belts 1 and 6 bear against the teeth 27 of the belts 25 and 26 when winding the curtain. Thus, these additional belts 25 and 26 form a discontinuous rim 4.

Il est bien entendu que la présente invention n'est pas limitée aux formes de réalisation décrites ci-dessus et à celles montrées dans les figures annexées, mais que d'autres variantes peuvent être envisagées sans sortir du cadre de la présente invention.It is understood that the present invention is not limited to the embodiments described above and those shown in the accompanying figures, but that other variants can be envisaged without departing from the scope of the present invention.

C'est ainsi que le rebord peut se situer du côté du rideau opposé à celui orienté vers le centre de courbure du rideau enroulé. Par ailleurs, une rainure peut séparer le rebord 4 des dents de la courroie correspondante.Thus the rim may be located on the side of the curtain opposite to that oriented towards the center of curvature of the curtain curtain. Furthermore, a groove can separate the rim 4 of the teeth of the corresponding belt.

La forme des dents des courroies peut être très variable et peut, par exemple, avoir une section transversale rectangulaire, trapézoïdale ou en forme de crampons.The shape of the teeth of the belts may be very variable and may, for example, have a rectangular, trapezoidal or spike-shaped cross section.

Le rebord 4 est de préférence continu, mais peut également comprendre une succession de saillies alignées suivant la direction longitudinale des bords latéraux du rideau.The flange 4 is preferably continuous, but may also comprise a succession of projections aligned in the longitudinal direction of the lateral edges of the curtain.
