Description

Porte à repliement et dispositif de guidage de rideau La présente invention concerne une porte à rideau souple à repliement et un dispositif de guidage du rideau de la porte. Dans le domaine des portes à rideau souple, on distingue les portes dites à enroulement dans lesquelles un rideau souple s'enroule sur un arbre et les portes dites à repliement dans lesquelles, au cours de l'ouverture du rideau, celui-ci se replie en accordéon au sommet de la porte. Les portes de ce dernier type présentent, de manière schématique, deux glissières verticales au sommet desquelles est placé un arbre entraîné par un moteur électrique. Le rideau est suspendu à une barre transversale située au-dessous de l'arbre d'enroulement et présente à son extrémité inférieure une barre de seuil. Deux sangles verticales et parallèles fixées, d'une part, à la barre de seuil et, d'autre part, à l'arbre d'enroulement permettent de relever le rideau lors de la mise en rotation de l'arbre. Le rideau dans sa position relevée s'amasse en accordéon dans la partie haute de la porte et ouvre le passage. De manière habituelle, le rideau est pourvu de plusieurs fourreaux dans lesquels sont insérés des barres de raidissement. Un problème important qui se pose pour ces portes est celui de la gestion de l'étanchéité entre les bords latéraux du rideau et les montants verticaux. En effet, pour réceptionner le rideau en position haute, les glissières présentent généralement une section transversale en forme de C dont les deux ailes sont distantes de 300 à 600 mm. Cette distance permet de réceptionner, entre les deux ailes du montant, les plis en accordéon du rideau lorsqu'il est relevé. La conséquence de la grande ouverture des montants est que, lorsque du vent souffle, le rideau a tendance à battre et un échange d'air se produit par les bordures latérales de celui-ci. L'invention vise à remédier à ces inconvénients et a pour but d'améliorer l'étanchéité d'une porte à repliement. A cet effet, l'invention a pour objet une porte comprenant, de manière connue en soi, deux glissières verticale, et au moins un rideau souple pouvant être replier dans la partie supérieure des glissières, présentant au moins une barre transversale de raidissement. Selon l'invention, un dispositif de guidage est engagé dans le prolongement d'au moins une barre de raidissement réalisant un guidage du rideau dans au moins l'une des glissières dans un plan déporté par rapport au plan du rideau, le rideau venant en applique contre une surface de la glissière. Ainsi, l'idée de base de l'invention consiste à réaliser un guidage du rideau pour éviter que celui-ci ne batte lorsqu'il est exposé à des rafales de vent, ce guidage étant déporté par rapport au plan du rideau pour permettre un appui surfacique du rideau sur une surface des glissières. Cette mise en applique du rideau contre une surface de chaque glissière empêche qu'un échange d'air ne se produise au niveau des bords latéraux du rideau. Cette disposition est tout à fait remarquable puisqu'elle autorise le repliement du rideau en partie haute de la porte, et ce à l'extérieure de la glissière, tout en préservant l'étanchéité. Selon un mode de réalisation avantageux, le dispositif de guidage présente au moins un organe de guidage dont l'axe est déporté par rapport au plan du rideau. Pour que le repliement du rideau se fasse de manière harmonieuse, la liaison entre le dispositif de guidage et la barre de raidissement autorise une rotation du dispositif de guidage par rapport à la barre de raidissement. Pour éviter qu'une action accidentelle contre le rideau ne se traduise pas un dégât coûteux à réparer sur celui-ci, au moins l'une des liaisons entre les dispositifs de guidage et d'une part la barre de raidissement et d'autre part la glissière est susceptible de se disloquer sans une sollicitation extérieure excédant une valeur prédéterminée. Ainsi avant une déformation permanente de la barre de raidissement ou de la glissière, le dispositif de guidage se brise pour éviter des dégâts irréversibles sur la porte. De préférence, le dispositif de guidage (14) présente au moins une zone de rupture ou de déformation susceptible de dégager le dispositif de guidage de la barre de raidissement (12) ou de la glissière (2). Selon une possibilité de réalisation de la porte dans laquelle elle comprend deux rideaux parallèles, celle-ci comprend un dispositif de guidage, pouvant s'engager sur un raidisseur appartenant à chacun des rideaux, présentant au moins un organe de guidage déporté par rapport au plan de chacune des rideaux. Dans cette possibilté de réalisation, une entretoise de liaison relie deux barres de raidissement, ce qui permet de créer un ensemble à forte inertie tout en étant d'une masse limitée. De préférence, chacune des glissière présente une première aile contre la face externe de laquelle le rideau vient en appui et une seconde aile délimitant avec la première aile une rainure recevant un organe de guidage du dispositif de guidage. De plus, le rideau présente une fenêtre au niveau de l'extrémité de chaque barre de raidissement par laquelle dépasse le dispositif de guidage. L'invention concerne également un dispositif de guidage qui comprend un corps présentant à l'une de ses extrémités, au moins un moyen d'engagement sur une barre de raidissement, et à sa seconde extrémité, au moins un organe de guidage dont l'axe est décalé par rapport à l'axe du moyen d'engagement sur la barre de raidissement. Là encore, l'idée de base de l'invention se retrouve, puisque le dispositif de guidage permet de réaliser un guidage du rideau dans un plan déporté par rapport au plan même du rideau, ce qui permet de ménager un espace permettant de mettre celui-ci en appui contre une . surface d'un glissière. Selon une possibilité de réalisation, le dispositif de guidage est constitué d'un corps présentant une grande base et une petite base parallèles, reliées par une paroi hémicylindrique perpendiculaire aux deux bases, la grande base étant équipée d'au moins un organe de guidage et la petite base présentant un trou borgne susceptible de recevoir une barre de raidissement. De façon avantageuse les organes de guidage comprennent : - une bague ayant une paroi hémicylindrique et une paroi plane placée dans le prolongement de la paroi hémicylindrique, et - un galet rotatif. La bague hémicylindrique prolonge la barre de raidissement et évite ainsi la formation de plis dans le rideau du rideau à l'extrémité de celle-ci. De façon avantageuse, la bague hémicylindrique renferme un galet. Selon une autre possibilité de réalisation, les organes de guidage sont constitués de deux galets orientés en V l'un par rapport à l'autre, susceptible de venir en appui contre une nervure présentant une section en V. Dans le cas d'un porte présentant deux rideaux parallèles le dispositif de guidage comprend un corps présentant une grande base et deux petites bases symétrique par rapport au plan médian, chacune des bases étant reliées à la grande base par une paroi hémicylindrique, la grande base étant équipée d'un moins un organe de guidage et chacunes de petites bases présent un trou borgne susceptible de recevoir une barre de raidissement. Dans ce cas, selon une possibilité, les organes de guidage comprennent : - un galet rotatif et - deux bagues symétriques par rapport au galet rotatif ayant chacune une paroi hémicylindrique placée dans le prolongement de chaque paroi hémicylindrique. Pour sa bonne compréhension l'invention est décrite en référence aux dessins ci-annexés représentant à titre d'exemples non limitatifs plusieurs formes de réalisation de portes à repliement et de dispositifs de guidage selon celle-ci. Figure 1 représente une porte vue de l'extérieure avec arrachement partiel du rideau au niveau de l'extrémité des barres de raidissement, Figure 2 représente en perspective depuis la zone intérieure délimitée par la porte deux dispositifs de guidage engagés dans une glissière, Figure 3 représente en perspective et en coupe le dispositif de guidage engagé dans une glissière, Figure 4 est une vue en coupe transversale au niveau de l'extrémité d'une barre de raidissement, Figure 5 est une vue également en coupe selon V-V de figure 2, Figure 6 représente la coupe Vl-VI de la figure 4, Figure 7 représente une variante de réalisation du dispositif de guidage, Figure 8 représente en coupe une autre forme de réalisation possible de du dispositif de guidage, Figure 9 représente en coupe une porte ayant deux rideaux parallèles. Par simplification, les éléments qui se retrouvent dans ces différentes formes de réalisation, ou qui sont similaires d'une forme de réalisation à une autre, sont désignés par les mêmes références numériques. En se référant tout d'abord à la figure 1 on peut voir que le dispositif de guidage selon l'invention trouve son application pour une porte comprenant deux glissières latérales 2 supportant à leur extrémité supérieure un arbre d'enroulement. Sur la figure 1 , l'arbre d'enroulement est caché par un capot transversal 3. Un rideau 4 souple est suspendu entre les deux glissières latérales 2 par une barre de suspension. A soη extrémité inférieure, le rideau 4 souple est équipé d'une barre de seuil 6 qui est reliée par des sangles 8 à l'arbre d'enroulement situé dans le carter 3. Les sangles 8 apparaissent au travers des fenêtres 9 transparentes pratiquées dans le rideau 4. Dans la description qui va suivre, par convention, on désignera par intérieure le côté de la porte sur lequel les sangles sont montées et par extérieur le côté de la porte sans sangle tel qu'il apparaît sur la figure 1 .The present invention relates to a flexible folding curtain door and a device for guiding the curtain of the door. In the field of flexible curtain doors, a distinction is made between so-called roller doors in which a flexible curtain is wound on a tree and so-called folding doors in which, during the opening of the curtain, it folds accordion at the top of the door. Doors of this latter type have, schematically, two vertical slides at the top of which is placed a shaft driven by an electric motor. The curtain is suspended from a transverse bar located below the winding shaft and has a threshold bar at its lower end. Two vertical and parallel straps fixed, on the one hand, to the threshold bar and, on the other hand, to the winding shaft make it possible to raise the curtain when the shaft is rotated. The curtain in its raised position collects in an accordion in the upper part of the door and opens the passage. Usually, the curtain is provided with several sleeves in which stiffening bars are inserted. An important problem which arises for these doors is that of managing the seal between the lateral edges of the curtain and the vertical uprights. In fact, to receive the curtain in the high position, the slides generally have a C-shaped cross section, the two wings of which are 300 to 600 mm apart. This distance makes it possible to receive, between the two wings of the upright, the accordion folds of the curtain when it is raised. The consequence of the wide opening of the uprights is that, when wind blows, the curtain tends to flap and an air exchange occurs through the side edges of it. The invention aims to remedy these drawbacks and aims to improve the tightness of a folding door. To this end, the subject of the invention is a door comprising, in a manner known per se, two vertical slides, and at least one curtain flexible can be folded into the upper part of the slides, having at least one stiffening crossbar. According to the invention, a guide device is engaged in the extension of at least one stiffening bar providing guidance of the curtain in at least one of the slides in a plane offset relative to the plane of the curtain, the curtain coming in applies against a surface of the slide. Thus, the basic idea of the invention consists in guiding the curtain to prevent it from beating when exposed to gusts of wind, this guidance being offset relative to the plane of the curtain to allow a surface support of the curtain on a surface of the slides. This application of the curtain against a surface of each slide prevents an exchange of air from occurring at the side edges of the curtain. This arrangement is quite remarkable since it allows the folding of the curtain in the upper part of the door, and this outside the slide, while preserving the seal. According to an advantageous embodiment, the guide device has at least one guide member whose axis is offset relative to the plane of the curtain. So that the folding of the curtain takes place in a harmonious manner, the connection between the guide device and the stiffening bar allows a rotation of the guide device relative to the stiffening bar. To avoid that an accidental action against the curtain does not result in costly damage to repair thereon, at least one of the connections between the guide devices and on the one hand the stiffening bar and on the other hand the slide is likely to dislocate without external stress exceeding a predetermined value. Thus before a permanent deformation of the stiffening bar or the slide, the guide device breaks to avoid irreversible damage to the door. Preferably, the guide device (14) has at least one rupture or deformation zone capable of disengaging the guide device from the stiffening bar (12) or from the slide (2). According to a possible embodiment of the door in which it comprises two parallel curtains, it comprises a guide device, which can engage on a stiffener belonging to each of curtains, having at least one guide member offset relative to the plane of each of the curtains. In this possible embodiment, a connecting spacer connects two stiffening bars, which makes it possible to create an assembly with high inertia while being of limited mass. Preferably, each of the slides has a first wing against the external face of which the curtain comes to rest and a second wing delimiting with the first wing a groove receiving a guide member of the guide device. In addition, the curtain has a window at the end of each stiffening bar through which protrudes the guide device. The invention also relates to a guide device which comprises a body having at one of its ends, at least one means of engagement on a stiffening bar, and at its second end, at least one guide member, the axis is offset from the axis of the engagement means on the stiffening bar. Here again, the basic idea of the invention is found again, since the guide device makes it possible to guide the curtain in a plane offset relative to the plane of the curtain itself, which makes it possible to provide a space for placing that -this in support against a. surface of a slide. According to one possible embodiment, the guide device consists of a body having a large parallel base and a small base, connected by a semi-cylindrical wall perpendicular to the two bases, the large base being equipped with at least one guide member and the small base having a blind hole capable of receiving a stiffening bar. Advantageously, the guide members comprise: - a ring having a semi-cylindrical wall and a flat wall placed in the extension of the semi-cylindrical wall, and - a rotary roller. The semi-cylindrical ring extends the stiffening bar and thus avoids the formation of folds in the curtain of the curtain at the end thereof. Advantageously, the semi-cylindrical ring contains a roller. According to another possible embodiment, the guide members consist of two rollers oriented in V relative to one another, capable of coming to bear against a rib having a V-shaped section. In the case of a door having two parallel curtains the guide device comprises a body having a large base and two small bases symmetrical with respect to the median plane, each of the bases being connected to the large base by a semi-cylindrical wall, the large base being equipped with at least one guide member and each of small bases has a blind hole capable of receiving a stiffening bar. In this case, according to one possibility, the guide members comprise: - a rotary roller and - two rings symmetrical with respect to the rotary roller each having a semi-cylindrical wall placed in the extension of each semi-cylindrical wall. For a good understanding of the invention is described with reference to the accompanying drawings showing by way of nonlimiting examples several embodiments of folding doors and guiding devices according thereto. Figure 1 shows a door seen from the outside with partial cutout of the curtain at the end of the stiffening bars, Figure 2 shows in perspective from the interior area delimited by the door two guide devices engaged in a slide, Figure 3 shows in perspective and in section the guide device engaged in a slide, FIG. 4 is a cross-section view at the end of a stiffening bar, Figure 5 is a view also in section along VV of Figure 2, Figure 6 shows the section VI-VI of Figure 4, Figure 7 shows an alternative embodiment of the guide device, Figure 8 shows in section another possible embodiment of the guide device, Figure 9 shows in section a door having two parallel curtains. For simplicity, the elements which are found in these different embodiments, or which are similar from one embodiment to another, are designated by the same reference numerals. Referring first to Figure 1 we can see that the guide device according to the invention finds its application for a door comprising two side rails 2 supporting at their upper end a winding shaft. In Figure 1, the winding shaft is hidden by a transverse cover 3. A flexible curtain 4 is suspended between the two side rails 2 by a suspension bar. At soη lower end, the flexible curtain 4 is equipped with a threshold bar 6 which is connected by straps 8 to the winding shaft located in the housing 3. The straps 8 appear through transparent windows 9 made in the curtain 4. In the description which follows, by convention, the interior of the door will be designated on which the straps are mounted and the exterior of the side of the door without the strap as it appears in FIG. 1.
Ceci correspond à la disposition de montage habituelle de ces portes. On comprend cependant que la distinction entre intérieur et extérieur a simplement pour but de simplifier la description de ces portes mais que la porte peut bien entendu séparer deux chambres situées chacune dans même un bâtiment. De manière usuelle, le rideau 4 présente à intervalles réguliers des fourreaux s'étendant sur toute sa largeur dans lesquels sont insérés des barres de raidissement 12. En se reportant à la figure 2 ou à la figure 3, on peut voir qu'un dispositif de guidage 14 est disposé dans le prolongement de chacune des barres de raidissement. Le dispositif de guidage 14 comprend un corps de forme sensiblement trapézoïdale présentant une grande base 16 et une petite base 17 parallèles, ces deux bases étant reliées d'une part par une paroi hémicylindrique perpendiculaire 18 aux deux bases et par une paroi hémicylindrique oblique 19. On note également que le corps du dispositif de guidage est constitué de deux demi coques 20a, 20b réalisées par moulage dans un matériau présentant une certaine élasticité. Comme le représente clairement la figure 3, la grande base du corps est équipée d'une bague hémicylindrique 22 et d'un galet rotatif 23. La bague hémicylindrique 22 tout comme le galet 23 sont montés sur deux axes 25,26 pris en sandwich entre les deux demi coquesThis corresponds to the usual mounting arrangement of these doors. It is understood, however, that the distinction between interior and exterior is simply intended to simplify the description of these doors but that the door can of course separate two rooms each located in the same building. In the usual way, the curtain 4 has at regular intervals sleeves extending over its entire width in which stiffening bars 12 are inserted. Referring to Figure 2 or Figure 3, it can be seen that a guide device 14 is arranged in the extension of each of the stiffening bars. The guide device 14 comprises a body of substantially trapezoidal shape having a large base 16 and a small base 17 parallel, these two bases being connected on the one hand by a semi-cylindrical wall perpendicular 18 to the two bases and by an oblique semi-cylindrical wall 19. It is also noted that the body of the guide device consists of two half shells 20a, 20b produced by molding in a material having a certain elasticity. As clearly shown in Figure 3, the large base of the body is equipped with a semi-cylindrical ring 22 and a rotary roller 23. The semi-cylindrical ring 22 as the roller 23 are mounted on two axes 25,26 sandwiched between the two half shells
20a, 20b. Une caractéristique importante, comme on le verra plus loin, est que la bague hémicylindrique 22 se situe dans le prolongement de la paroi hémicylindrique 18 du corps. Au niveau de la petite base 16, le corps présente un trou borgne prolongé par une collerette 28. Un élément à prendre en considération dans la porte selon l'invention est constitué par les deux glissières 2 latérales. Comme on peut le voir en coupe transversale sur la figure 6, chacune des glissières présente une aile extérieure 28 et une aile intérieure29, ces deux ailes étant parallèles. On note également que la glissière 2 présente un prolongement 30 vers l'extérieur, perpendiculaire à l'aile extérieure 28. Un autre élément caractéristique de cette porte est constitué par des fenêtres 32 ménagées dans le rideau au niveau de l'extrémité de chaque barre de raidissement. On rappelle que le rideau présente une structure multicouche, spécialement au niveau des barres de raidissement 12. Celles-ci sont insérées dans un fourreau constitué par une bande 34 de matériau souple soudée sur u écrou 35 pour former le fourreau. Le fonctionnement de la porte est donc le suivant. Comme on peut le voir sur la figure 2 ou sur la figure 3 le dispositif de guidage 14 est emmanché sur chaque extrémité des barres de raidissement 12. Le diamètre du trou borgne par rapport à celui de la barre de raidissement est tel que le dispositif de guidage est libre en rotation par rapport à la barre de raidissement 12. Le blocage en translation du dispositif de guidage est réalisé par la fenêtre 32 puisque au niveau de sa paroi oblique le dispositif de guidage dépasse de cette fenêtre, mais comme on peut le voir sur la figure 4, est retenu dans la direction axiale de la barre de raidissement 12 par les bords de la fenêtre 32. Le guidage du rideau est alors réalisé par la bague hémicylindrique 22 dont la paroi plane est en appui contre la face extérieure de l'aile 28 et dont le galet 23 est bordé par la face 28 de l'aile extérieure et par la face extérieure de l'aile 29. Grâce à ce dispositif de guidage on constate donc que le rideau est parfaitement guidé par rapport aux glissières 2 et que, comme le montre la figure 5, qui montre une coupe transversale de la porte entre deux barres de raidissement 12, le rideau 4 vient en applique contre la face extérieure de l'aile extérieure. Cette caractéristique est particulièrement avantageuse lorsque du vent souffle puisque l'action du vent tend à plaquer alors les bords latéraux du rideau 4 contre chacune des ailes 28 dont les glissières sont pourvues. Il est également à remarquer que lorsque du vent souffle dans une direction transversale, c'est-à-dire parallèlement au plan du rideau 4, le prolongement 30 dont les glissières sont équipées protège de l'entrée d'un courant d'air latéral. En cas de relèvement du rideau, le dispositif de guidage 14 glisse donc par rapport aux glissières 2. Un point qu'il est important de relever est que la formation de plis dans la partie haute de la porte se fait harmonieusement d'une part parce que les dispositifs de guidage 14 peuvent pivoter par rapport aux barres de raidissement et d'autre part parce que les bagues hémicylindriques 22 situées dans le prolongement du corps réalisent avec les barres de raidissement 12 un élément hémicylindrique sur toute la largeur du rideau. Enfin, il est à noter que la porte ainsi définie présente un comportement remarquable vis-à-vis de chocs qu'elle pourrait subir. Il est en effet à noter que lorsque la porte est sollicitée accidentellement depuis l'extérieur, elle offre une possibilité de désengagement des embouts des glissières sans dégâts irréversibles du rideau 4. En effet, lors d'une action accidentelle contre le rideau 4, la barre de raidissement 12 fléchie et les dispositifs de guidage se dégagent des glissières. Ce dégagement peut se faire de deux manières. Soit le fléchissement de la barre entraîne le dégagement du galet 23 et de la bague hémisphérique 22 de chacune des ailes 28,29 ; on note au passage qu'il faut donc vaincre la réaction de deux surfaces d'appui puisque la bague 22 hémisphérique est en appui contre l'aile extérieure 28 et le galet 23 est en appui contre l'aile intérieure29. Soit dans un deuxième mode de dégagement du dispositif de guidage, le dégagement est obtenu par l'ouverture des deux demi coques 20a, 20b l'une par rapport à l'autre puisque, . comme on l'a vu, celles-ci sont réalisées dans un matériau élastique. Ainsi, l'extrémité de la barre de raidissement peut échapper du dispositif par l'ouverture de ces deux demi coques 20a, 20b du fait de leur déformation élastique. Lors d'un choc accidentel depuis l'intérieur, le même mode de dégagement se produit, sachant que dans ce cas seul le galet 23 est en appui contre l'aile extérieure 28. La figure 7 représente une variante de réalisation dans laquelle un galet 39 est inséré dans la bague hémicylindrique. Ce galet 39 dépasse du rideau 4 par une fenêtre spécifique réalisée dans celui-ci qui permet à ce galet 39 d'être en contact de l'aile extérieure 29. Cette variante de réalisation permet de préserver l'intégrité du rideau 4 au niveau de sa zone de frottement contre l'aile extérieure 28. La figure 8 représente une autre possibilité de réalisation dans laquelle les organes de guidage sont constitués de deux galets 41 orientés en V l'un par rapport à l'autre, susceptible de venir en appui contre une nervure 42 présentant une section en V. La figure 9 représente une porte ayant deux rideaux. Selon cette forme de réalisation, celle-ci comprend un dispositif de guidage, pouvant s'engager sur un raidisseur appartenant à chacun des rideaux, présentant un organe de guidage déporté par rapport au plan de chacune des rideaux. Le dispositif de guidage comprend deux bagues hémicylindriques 22 encadrant un galet 23. Dans cette possibilté de réalisation, une entretoise de liaison 44 relie deux barres de raidissement 12, ce qui permet de créer un ensemble à forte inertie tout en étant d'une masse limitée. La porte ainsi décrite présente donc de nombreux avantages puisqu'elle garantit un guidage latéral de son rideau ainsi qu'une très grande étanchéité latérale. L'invention a été décrite ci-dessus en référence à un exemple de réalisation non limitatif mais elle en embrasse bien entendu toutes les formes de réalisation. Ainsi les glissières paraissent être en deux parties, le prolongement 30 étant formé par un capot rapporté. 20a, 20b. An important characteristic, as will be seen below, is that the semi-cylindrical ring 22 is located in the extension of the semi-cylindrical wall 18 of the body. At the small base 16, the body has a blind hole extended by a flange 28. An element to be taken into consideration in the door according to the invention is constituted by the two lateral slides 2. As can be seen in cross section in Figure 6, each of the slides has an outer wing 28 and an inner wing29, these two wings being parallel. It is also noted that the slide 2 has an extension 30 towards the outside, perpendicular to the outer wing 28. Another characteristic element of this door is constituted by windows 32 formed in the curtain at the end of each bar stiffening. It will be recalled that the curtain has a multilayer structure, especially at the level of the stiffening bars 12. These are inserted in a sheath constituted by a strip 34 of flexible material welded to a nut 35 to form the sheath. The operation of the door is therefore as follows. As can be seen in Figure 2 or in Figure 3 the guide device 14 is fitted on each end of the stiffening bars 12. The diameter of the blind hole relative to that of the stiffening bar is such that the device guide is free to rotate relative to the stiffening bar 12. The guide device is locked in translation by the window 32 since, at its oblique wall, the guide device protrudes from this window, but as can be seen in FIG. 4, is retained in the axial direction of the stiffening bar 12 by the edges of the window 32. The curtain is then guided by the semi-cylindrical ring 22, the flat wall of which bears against the outer face of the wing 28 and the roller 23 of which is bordered by the face 28 of the outer wing and by the outer face of the wing 29. Thanks to this guide device, it can therefore be seen that the curtain is perfectly guided pa r compared to the rails 2 and that, as shown in FIG. 5, which shows a cross section of the door between two stiffening bars 12, the curtain 4 comes to bear against the outer face of the outer wing. This characteristic is particularly advantageous when the wind is blowing since the action of the wind tends to press the lateral edges of the curtain 4 against each of the wings 28 with which the slides are provided. It should also be noted that when wind blows in a transverse direction, that is to say parallel to the plane of the curtain 4, the extension 30 with which the slides are equipped protects from the entry of a lateral air current . When the curtain is raised, the guide device 14 therefore slides relative to the rails 2. One point which is important to note is that the formation of folds in the upper part of the door is done harmoniously on the one hand because that the guide devices 14 can pivot relative to the stiffening bars and on the other hand because the semi-cylindrical rings 22 located in the extension of the body produce with the stiffening bars 12 a semi-cylindrical element over the entire width of the curtain. Finally, it should be noted that the door thus defined exhibits a remarkable behavior with respect to shocks that it could undergo. It should be noted that when the door is accidentally pressed from the outside, it offers a possibility of disengagement of the end pieces of the slides without irreversible damage to the curtain 4. In fact, during an accidental action against the curtain 4, the stiffening bar 12 bent and the guide devices disengage from the slides. This release can be done in two ways. Either the deflection of the bar causes the release of the roller 23 and the hemispherical ring 22 of each of the wings 28, 29; it should be noted in passing that it is therefore necessary to overcome the reaction of two bearing surfaces since the hemispherical ring 22 is in abutment against the outer wing 28 and the roller 23 is in abutment against the inner wing29. Either in a second release mode of the guide device, the release is obtained by the opening of the two half-shells 20a, 20b relative to each other since,. as we have seen, these are made of an elastic material. Thus, the end of the stiffening bar can escape from the device by the opening of these two half shells 20a, 20b due to their elastic deformation. During an accidental impact from the inside, the same release mode occurs, knowing that in this case only the roller 23 is in abutment against the outer wing 28. FIG. 7 shows an alternative embodiment in which a roller 39 is inserted into the semi-cylindrical ring. This roller 39 protrudes from the curtain 4 by a specific window made therein which allows this roller 39 to be in contact with the outer wing 29. This variant embodiment preserves the integrity of the curtain 4 at its zone of friction against the outer wing 28. FIG. 8 represents another possible embodiment in which the guide members consist of two rollers 41 oriented in V relative to one another, capable of coming to bear against a rib 42 having a V-shaped section. FIG. 9 represents a door having two curtains. According to this embodiment, it comprises a guide device, which can engage on a stiffener belonging to each of the curtains, having a guide member offset relative to the plane of each of the curtains. The guide device comprises two semi-cylindrical rings 22 surrounding a roller 23. In this possible embodiment, a connecting spacer 44 connects two stiffening bars 12, which makes it possible to create an assembly with high inertia while being of limited mass. The door thus described therefore has many advantages since it guarantees lateral guidance of its curtain as well as very high lateral tightness. The invention has been described above with reference to a non-limiting exemplary embodiment, but it of course embraces all of the embodiments thereof. Thus the slides appear to be in two parts, the extension 30 being formed by an attached cover.
