Once the door is in the closed position the panel can be deployed into the doorway and the seal inflated.

Description

La présente invention concerne un ensemble formant une porte coulissante étanche, notamment pour local à atmosphère contrôlée tel qu'un laboratoire.The present invention relates to an assembly forming a door waterproof sliding, especially for rooms with controlled atmosphere such than a laboratory.

Il est bien connu de rendre une porte parfaitement étanche en l'équipant d'un joint périphérique conformé pour être pressé étroitement contre un siège correspondant lorsque la porte est en position de fermeture. Ce joint peut notamment être du type gonflable.It is well known to make a door perfectly watertight by equipping it with a peripheral seal shaped to be pressed tightly against a corresponding seat when the door is in position closing. This seal can in particular be of the inflatable type.

Ce genre de porte ne pose pas de problèmes particuliers dès lors qu'il est possible de mettre en place une porte pivotante. Par contre, la mise en place d'une porte coulissante, notamment dans le cas où l'espace nécessaire au débattement d'une porte pivotante fait défaut, est problématique. Il n'est en effet possible actuellement de recourir qu'à une porte à joint classique, présentant une structure et des moyens de guidage complexes puisque devant permettre un déplacement de la porte vers la paroi dans laquelle est aménagée la baie à fermer, ce déplacement permettant, en fin de mouvement de fermeture de la porte, de faire porter le joint contre le siège correspondant qui est aménagé dans ladite paroi ou dans une huisserie.This kind of door does not pose any particular problems as soon as when it is possible to install a pivoting door. On the other hand, the installation of a sliding door, especially in the case where the space required for the travel of a pivoting door is lacking, is problematic. It is currently only possible to use one conventional seal door, having a structure and guide means complex since they should allow the door to move to the wall in which the opening to be closed is fitted, this displacement allowing, at the end of the door closing movement, to carry the seal against the corresponding seat which is arranged in said wall or in a frame.

Une telle porte n'a pas une étanchéité suffisante ou des conditions de fonctionnement lui permettant d'être utilisée pour la fermeture de locaux particuliers, tels que les locaux à atmosphère contrôlée.Such a door does not have sufficient tightness or operating conditions allowing it to be used for the closing of specific rooms, such as rooms with atmosphere controlled.

La demande de brevet français n° 2 642 107 décrit une porte coulissante comprenant un joint gonflable, ce joint étant fixé sur la face de la porte tournée vers la paroi dans laquelle la baie est aménagée. Ce joint vient, en position de fermeture de la porte, porter contre cette paroi.French patent application No. 2,642,107 describes a door sliding comprising an inflatable seal, this seal being fixed on the face of the door facing the wall in which the bay is fitted. This joint comes, in the closed position of the door, to bear against this wall.

La porte selon cette demande de brevet a pour inconvénient majeur d'impliquer un ancrage particulièrement solide des moyens de guidage de la porte, à même de résister à la contrainte importante et prolongée exercée par la mise du joint en pression.The door according to this patent application has the disadvantage major to involve a particularly solid anchoring of the means of door guide, able to withstand the significant stress and prolonged exerted by the pressurized seal.

En outre, la présence du joint sur la porte crée des recoins dans lesquels de la poussière pourrait s'accumuler, ce qui n'est guère souhaitable dans une application à la fermeture de locaux à atmosphère contrôlée.In addition, the presence of the seal on the door creates recesses in which dust could collect, which is hardly desirable in an application to the closing of rooms with atmosphere controlled.

La présente invention vise à remédier à ces inconvénients pratiques essentiels. The present invention aims to remedy these drawbacks essential practices.

L'ensemble qu'elle concerne comprend, de manière connue en soi, une porte munie d'un joint périphérique, ce joint étant conformé pour être pressé étroitement, lorsque la porte est en position de fermeture, contre des faces délimitant la baie à fermer, qui constituent un siège pour ce joint.The set which it concerns comprises, in a manner known in itself, a door provided with a peripheral seal, this seal being shaped to be pressed tightly, when the door is in the closed position, against faces delimiting the opening to be closed, which constitute a seat for this joint.

Selon l'invention, la porte comprend un panneau déplaçable par rapport à elle entre une position d'effacement, permettant le coulissement de la porte le long de la paroi dans laquelle est aménagée la baie à fermer, et une position d'extension, dans laquelle ce panneau est engagé dans cette baie, ledit panneau présentant des dimensions légèrement inférieures à celles de la baie, de sorte que ses faces périphériques viennent, dans ladite position d'extension, à proximité desdites faces délimitant la baie à fermer, et ce panneau comprenant ledit joint au niveau de ces faces périphériques.According to the invention, the door comprises a panel movable by relation to it between an erasing position, allowing sliding the door along the wall in which the opening to be closed is fitted, and an extension position, in which this panel is engaged in this bay, said panel having slightly smaller dimensions to those of the bay, so that its peripheral faces come, in said extended position, close to said faces delimiting the bay at close, and this panel comprising said joint at the level of these faces peripheral devices.

La mise en pression de ce joint exerce ainsi une contrainte sur le panneau et sur lesdites faces qui délimitent la baie, et non sur les ancrages des moyens de guidage de la porte en coulissement. Ces ancrages n'ont donc pas à présenter une solidité renforcée.The pressurization of this seal thus exerts a constraint on the panel and on said faces which delimit the bay, and not on the anchors of the sliding door guide means. These anchors therefore do not have to be reinforced.

La porte a un mouvement de fermeture/ouverture purement rectiligne, de sorte que les moyens de guidage ont en outre une structure qui reste simple.The door has a purely closing / opening movement straight, so that the guide means further have a structure which remains simple.

La porte peut avantageusement présenter un évidement de réception du panneau dans ladite position d'effacement, ayant des dimensions légèrement supérieures à celles de ce panneau.The door can advantageously have a recess of receiving the panel in said erasing position, having dimensions slightly larger than those of this panel.

Il n'existe ainsi qu'un interstice entre la porte et le panneau dans cette position d'effacement, qui prévient tout risque d'accumulation de poussière.There is thus only a gap between the door and the panel in this erasing position, which prevents any risk of accumulation of dust.

Selon une forme de réalisation simple de l'invention, le panneau est déplaçable en translation par rapport à la porte selon une direction perpendiculaire au plan de la porte, ce mouvement étant réalisé au moyen d'au moins un vérin relié à la porte d'une part et au panneau d'autre part, et de moyens de guidage en translation du panneau.According to a simple embodiment of the invention, the panel is movable in translation relative to the door in a direction perpendicular to the plane of the door, this movement being carried out by means at least one jack connected to the door on the one hand and to the panel on the other hand, and means for guiding the panel in translation.

De préférence, ces moyens de guidage sont constitués par des doigts solidaires de la porte ou du panneau, pouvant coulisser sans jeu latéral dans des manchons tubulaires correspondants solidaires respectivement du panneau ou de la porte. Preferably, these guide means are constituted by fingers secured to the door or panel, can slide without play lateral in corresponding tubular sleeves panel or door respectively.

Pour sa bonne compréhension, l'invention est à nouveau décrite ci-dessous en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme de réalisation préférée de l'ensemble formant une porte, qu'elle concerne.

  • La figure 1 en est une vue en coupe verticale, en position de fermeture étanche, et
  • la figure 2 en est une vue en coupe horizontale, en cours d'ouverture.
    • For a good understanding, the invention is again described below with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, a preferred embodiment of the assembly forming a door, which it relates to.
  • FIG. 1 is a view in vertical section thereof, in the sealed closure position, and
  • Figure 2 is a horizontal sectional view, during opening.

    • Les figures représentent un ensemble 1 formant une porte coulissante étanche, notamment pour local à atmosphère contrôlée tel qu'un laboratoire.The figures represent a set 1 forming a door waterproof sliding, especially for rooms with controlled atmosphere such than a laboratory.

    Cet ensemble 1 comprend une huisserie 2, fixée en applique contre la paroi 3 dans laquelle est aménagée la baie à fermer, une porte 4 montée coulissante le long de cette huisserie 2, des moyens supérieurs et inférieurs de guidage de la porte 4 en coulissement, et des moyens de commande et de contrôle du mouvement de la porte 4. Ces derniers ne font pas partie de l'invention et sont bien connus en eux-mêmes, de sorte qu'ils ne sont pas représentés au dessin et qu'ils ne seront pas décrits en détail.This set 1 includes a frame 2, fixed to the wall against the wall 3 in which the opening to be closed is arranged, a door 4 sliding rise along this frame 2, upper means and sliding guide of the door 4, and means for command and control of the movement of door 4. These do not are not part of the invention and are well known in themselves, so that they are not shown in the drawing and that they will not be described in detail.

    L'huisserie 2 présente une forme de cadre dont les faces intérieures 2a délimitent la baie à fermer. Elle comporte un montant latéral 5 dans lequel est fixé un électro-aimant 6 assurant l'immobilisation de la porte 4 en position de fermeture.The frame 2 has a form of frame whose faces interior 2a delimit the bay to be closed. It has a lateral upright 5 in which is fixed an electromagnet 6 ensuring the immobilization of the door 4 in the closed position.

    La porte 4 se présente sous la forme d'un caisson formé par assemblage de profilés et de tôles pliées. Du côté de la paroi 3, cette porte 4 comprend un évidement 10 dont les dimensions correspondent sensiblement à celles de la baie à fermer.The door 4 is in the form of a box formed by assembly of folded sections and sheets. On the side of wall 3, this door 4 includes a recess 10 whose dimensions correspond substantially to those of the bay to be closed.

    La porte 4 comprend un deuxième évidement 11, plus profond que l'évidement 10 et de dimensions plus réduites que celui-ci, au niveau duquel sont fixés les tiges de piston 12a de plusieurs vérins 12 ainsi que plusieurs doigts 13 de guidage. Ces vérins 12 et doigts 13 sont placés mutuellement en des emplacements éloignés les uns des autres, un seul de ces vérins 12 et un seul de ces doigts 13 étant représentés sur les figures, par souci de clarté du dessin. L'évidement 11 peut par exemple être rectangulaire et la porte 4 peut comprendre quatre vérins 12 et quatre doigts de guidage 13 fixés à proximité des angles de cet évidement 11. Door 4 includes a second, deeper recess 11 that the recess 10 and of smaller dimensions than this, at the level which are fixed the piston rods 12a of several cylinders 12 as well as several guide fingers 13. These jacks 12 and fingers 13 are placed each other in remote locations, only one of these jacks 12 and only one of these fingers 13 being shown in the figures, for the sake of clarity of the drawing. The recess 11 can for example be rectangular and door 4 can include four cylinders 12 and four guide fingers 13 fixed near the corners of this recess 11.

    A sa partie supérieure, la porte 4 comprend deux pattes 15 sur lesquelles sont montés des galets 16, ces galets 16 étant engagés et pouvant rouler dans un rail de guidage 17, solidaire de l'huisserie 2.At its upper part, the door 4 comprises two legs 15 on which are mounted rollers 16, these rollers 16 being engaged and can roll in a guide rail 17, integral with the frame 2.

    La porte 4 est également reliée à des moyens d'actionnement et de transmission (non représentés et non détaillés car bien connus en eux-mêmes), permettant son actionnement en coulissement. Un capot 18 solidaire de l'huisserie 2 recouvre l'ensemble des moyens supérieurs de guidage et d'actionnement de la porte 4, ainsi que le bord supérieur de cette dernière.The door 4 is also connected to actuation means and transmission (not shown and not detailed because they are well known in themselves), allowing its sliding actuation. A cover 18 integral with the frame 2 covers all of the upper means of guide and actuation of door 4, as well as the upper edge of the latter.

    A sa partie inférieure, la porte 4 comprend une rainure 20 dans laquelle est engagé, avec possibilité de coulissement, un rail 21 solidaire d'une plaque 22. Cette plaque 22 est reliée à l'huisserie 2.At its lower part, the door 4 comprises a groove 20 in which is engaged, with the possibility of sliding, a rail 21 integral of a plate 22. This plate 22 is connected to the frame 2.

    La porte 4 comprend également, du côté de la paroi 3, un panneau 25 déplaçable entre une position d'extension montrée à la figure 1 et une position d'effacement montrée à la figure 2.The door 4 also includes, on the side of the wall 3, a panel 25 movable between an extension position shown in the figure 1 and an erasing position shown in FIG. 2.

    Ce panneau 25 est également formé par assemblage de profilés et de tôles pliées. Il présente des dimensions légèrement inférieures à l'évidement 10, et donc à la baie à fermer, de sorte qu'il peut, en position d'extension, être engagé dans cette baie avec ses faces périphériques venant à proximité des faces 2a de l'huisserie 2, et qu'il peut, en position d'effacement, être engagé dans l'évidement 10.This panel 25 is also formed by assembling profiles and folded sheets. It has dimensions slightly smaller than the recess 10, and therefore at the opening to be closed, so that it can, in position extension, be engaged in this bay with its peripheral faces coming near the faces 2a of the frame 2, and that it can, in position delete, be engaged in the recess 10.

    Il apparaít à la figure 2 que la profondeur de cet évidement 10 et que l'épaisseur du panneau 25 sont telles que le panneau 25, dans cette position d'effacement, est situé au-delà de l'huisserie 2, de sorte qu'il ne fait pas obstacle au coulissement de la porte 4 le long de la paroi 3, et que sa face 25a tournée du côté de l'huisserie 2 affleure sensiblement avec la face voisine de la porte 4, en ne laissant subsister qu'un interstice entre ces faces.It appears in Figure 2 that the depth of this recess 10 and that the thickness of the panel 25 is such that the panel 25, in this erasing position, is located beyond the frame 2, so that it does not prevent the sliding of door 4 along the wall 3, and that its face 25a turned towards the side of the frame 2 is flush substantially with the neighboring face of door 4, while not allowing it to remain that a gap between these faces.

    Le panneau 25 comprend un évidement central 26 de dimensions correspondant sensiblement à celles de l'évidement 11, au niveau duquel sont fixés les corps 12b des vérins 12 ainsi que des manchons tubulaires 27. Les doigts 13 sont engagés et peuvent coulisser sans jeu latéral dans ces manchons tubulaires 27.The panel 25 includes a central recess 26 of dimensions substantially corresponding to those of the recess 11, at level from which the bodies 12b of the jacks 12 are fixed as well as tubular sleeves 27. The fingers 13 are engaged and can slide without lateral play in these tubular sleeves 27.

    Le panneau 2 comprend en outre un joint gonflable 30 logé dans une rainure. Cette rainure est aménagée au niveau des faces périphériques du panneau 25, et ce joint 30 s'étend sur l'ensemble de la périphérie de ce dernier.The panel 2 further comprises an inflatable seal 30 housed in a groove. This groove is arranged at the faces peripherals of the panel 25, and this joint 30 extends over the entire periphery of the latter.

    Il apparaít aux figures que le joint 30 se situe en retrait de ces faces périphériques lorsqu'il est dégonflé, de sorte qu'il ne fait pas obstacle au mouvement du panneau 25 entre les positions d'extension et d'effacement précitées. Ce joint 30 se situe en saillie de ces mêmes faces lorsqu'il est gonflé, de sorte qu'il vient étroitement en appui contre les faces 2a.It appears in the figures that the seal 30 is set back from these peripheral faces when deflated so that it doesn't obstacle to movement of the panel 25 between the extension positions and above. This seal 30 is located projecting from these same faces when inflated, so that it comes into close contact with the faces 2a.

    Dans cette position, le joint 30 assure une parfaite étanchéité de la porte 4. Pour l'ouverture de cette dernière, le joint 30 est dégonflé puis les vérins 12 sont actionnés pour amener le panneau 25 dans sa position d'effacement montrée à la figure 2. La porte 4 peut alors coulisser vers une position d'ouverture, libérant la baie.In this position, the seal 30 ensures a perfect seal of door 4. To open the latter, the seal 30 is deflated then the jacks 12 are actuated to bring the panel 25 into its delete position shown in Figure 2. Door 4 can then slide towards an open position, freeing the bay.

    L'invention fournit ainsi un ensemble formant une porte coulissante étanche, qui permet de remédier aux inconvénients des ensembles homologues de la technique antérieure. Il assure en effet une parfaite étanchéité, ce qui lui permet d'être utilisé pour la fermeture de locaux particuliers, tels que les locaux à atmosphère contrôlée, sans nécessiter des ancrages particulièrement solides pour les moyens de guidage de la porte, et sans que ces moyens de guidage n'aient une structure complexe. En outre, l'interstice précité permet de prévenir tout risque d'accumulation de poussière.The invention thus provides an assembly forming a door. sliding door, which overcomes the disadvantages of homologous sets of the prior art. It effectively perfect seal, which allows it to be used for closing special rooms, such as rooms with controlled atmosphere, without require particularly strong anchors for the means of guiding the door, and without these guide means having a complex structure.
