Par exemple, une telle porte peut être destinée à équiper des entrepôts frigorifiques.The present invention relates to a liftable curtain door with reinforced thermal insulation, intended to equip a bay formed in a partition wall between two volumes of air at different temperatures. For example, such a door can be intended to equip cold stores.

De telles portes à rideau relevable comportent généralement deux montants latéraux, habituellement métalliques, dotés de glissières dans lesquelles coulissent des parties latérales du rideau relevable.Such liftable curtain doors generally have two lateral uprights, usually metallic, provided with slides in which lateral parts of the liftable curtain slide.

La présente invention a pour but de limiter les pertes thermiques dues à ces montants métalliques.The object of the present invention is to limit the heat losses due to these metal uprights.

Ainsi, la présente invention a pour objet une porte à rideau relevable, destinée à obturer une baie dans un mur entre deux volumes d'air à températures différentes, ladite porte comportant deux montants latéraux verticaux qui forment chacun une glissière délimitée par deux bords verticaux; ladite porte comportant un rideau relevable qui présente des parties latérales coulissant dans lesdites glissières, caractérisée en ce que chaque montant latéral comporte deux profilés verticaux métalliques qui forment chacun un bord vertical de la glissière et qui sont en outre séparés l'un de l'autre par une fente verticale s'étendant sur sensiblement toute la hauteur du montant, au moins un desdits profilés verticaux étant plus proche du mur et en contact étanche avec le mur et en contact sensiblement étanche avec le rideau sur toute la hauteur du rideau, au moins lorsque ledit rideau est baissé. Le rideau peut être en contact sensiblement étanche permanent, sur toute sa hauteur, avec ledit profilé vertical qui est en contact étanche avec le mur et/ou la porte peut comporter en outre des organes applicateurs, pour appliquer en contact sensiblement étanche le rideau contre ledit profilé vertical qui est en contact étanche avec le mur, lorsque ledit rideau est baissé.Thus, the subject of the present invention is a liftable curtain door, intended to close off a bay in a wall between two volumes of air at different temperatures, said door comprising two vertical lateral uprights which each form a slide delimited by two vertical edges; said door comprising a lifting curtain which has lateral parts sliding in said rails, characterized in that each lateral upright comprises two vertical metal profiles which each form a vertical edge of the rail and which are further separated from each other by a vertical slot extending over substantially the entire height of the upright, at least one of said vertical profiles being closer to the wall and in sealed contact with the wall and in substantially sealed contact with the curtain over the entire height of the curtain, at least when said curtain is lowered.

Comme représenté sur la figure 1, la présente invention concerne une porte destinée à obturer une baie 5 dans un mur 9, séparant deux volumes d'air de température différentes T1, T2. Par exemple, pour une porte d'entrepôt frigorifique, T1 peut valoir +20°C et T2 -40°C. La porte comporte un rideau 4 isolant relevable par enroulement et deux montants latéraux 1, 2 généralement métalliques, dotés chacun d'une glissière 8 de guidage du rideau 4. Dans l'exemple représenté sur la figure 1, les montants latéraux 1, 2 sont réunis à leurs extrémités supérieures par une traverse 3 qui contient le mécanisme d'actionnement du rideau, mais cette caractéristique pourait être omise sans sortir du cadre de la présente invention. La porte représentée sur la figure 1 est du type communément appelé "porte de manutention", c'est-à-dire une porte à ouverture rapide destinée à s'ouvrir au passage d'un engin de manutention et à se fermer après le passage dudit engin.As shown in Figure 1, the present invention relates to a door intended to close a bay 5 in a wall 9, separating two volumes of temperature air different T1, T2. For example, for a cold storage door, T1 can be + 20 ° C and T2 -40 ° C. The door comprises an insulating curtain 4 which can be raised by winding and two generally metal lateral uprights 1, 2, each provided with a slide 8 for guiding the curtain 4. In the example shown in FIG. 1, the lateral uprights 1, 2 are joined at their upper ends by a cross member 3 which contains the mechanism for actuating the curtain, but this characteristic could be omitted without departing from the scope of the present invention. The door shown in Figure 1 is of the type commonly called "handling door", that is to say a quick opening door intended to open to the passage of a handling machine and to close after the passage of said device.

Chaque montant latéral 1, 2 comporte une paroi frontale 7, qui est ici sensiblement perpendiculaire au rideau 4, et qui est dotée d'une fente longitudinale 8 formant ladite glissière. On notera que la paroi 7 ne doit pas nécessairement être perpendiculaire au rideau 4 : il suffit que la paroi 7 soit localement non parallèle au rideau 4 au voisinage de la fente 8. Dans l'exemple représenté sur la figure 1, les montants latéraux 1, 2 ont une section en forme de U, et comportent chacun deux parois 10 qui s'étendent sur une certaine distance à partir de ladite paroi 7, vers l'extérieur de la baie 5. Les montants latéraux peuvent avoir une section équivalente à une section en U, par exemple une section en H ou en V. Chaque montant latéral 1, 2 est constitué de deux profilés 26, 27 métalliques à section en L, qui sont séparés par la fente 8. Le profilé 27 de chaque montant latéral est en contact étanche contre le mur 9, de façon à minimiser les passages d'air au travers de la baie 5.Each lateral upright 1, 2 has a front wall 7, which is here substantially perpendicular to the curtain 4, and which is provided with a longitudinal slot 8 forming said slide. Note that the wall 7 does not necessarily have to be perpendicular to the curtain 4: it suffices that the wall 7 is locally not parallel to the curtain 4 in the vicinity of the slot 8. In the example shown in FIG. 1, the lateral uprights 1 , 2 have a U-shaped section, and each have two walls 10 which extend a certain distance from said wall 7, towards the outside of the opening 5. The lateral uprights can have a section equivalent to a U-shaped section, for example an H or V section. Each lateral upright 1, 2 consists of two metal sections 26, 27 with an L-shaped section, which are separated by the slot 8. The section 27 of each lateral upright is in tight contact against the wall 9, so as to minimize the air passages through the opening 5.

Le rideau 4 comporte des parties latérales qui coulissent dans les fentes 8 des montants 1 et 2. Dans l'exemple particulier de la figure 1, le rideau 4 est souple et relevable par enroulement et comporte des barres horizontales de renforcement 6 ayant des extrémités axiales 6a qui coulissent dans les fentes 8 et le rideau comporte des bords latéraux 4a qui coulissent aussi dans les fentes 8. Le rideau 4 peut éventuellement ne pas comporter de barres de renforcement 6. Dans les cas où le rideau 4 est susceptible de subir des chocs violents, dus par exemple à des véhicules de manutention, il peut être avantageux que les parties latérales du rideau qui coulissent dans les fentes 8 soient adaptées à se dégager desdites fentes 8 lors d'un choc violent sur le rideau 4, de façon à prévenir un endommagement dudit rideau. Des solutions à ce problème sont données dans les documents EP-A-0 398 791, EP-A-0 320 350, GB-A-1 597 396, EP-A-0 264 220 et EP-A-0 272 733. Dans l'exemple représenté, les fentes 8 sont assez étroites, de sorte que les parties latérales du rideau coulissent dans lesdites fentes 8, avec un faible jeu, donc en contact sensiblement étanche avec la paroi frontale 7 de chaque côté de la fente 8 de façon à minimiser le passage d'air au travers de la baie 5. L'étanchéité entre les bords latéraux 4a du rideau et les montants 1, 2 peut être améliorée en utilisant des bords latéraux épaissis, tel que par exemple celui représenté sur la figure 1a. Sur la figure 1a, le bord latéral 4a du rideau est doté de deux feuilles en matière souple élastique, fixées au rideau 4 et s'étendant en V vers l'extérieur du rideau. Lorsque le rideau coulisse dans les fentes 8 des montants 1, 2, les branches divergentes du V s'appuie élastiquement sur la paroi frontale 7, chacune d'un côté de la fente 8 en réalisant une étanchéité excellente. Les feuilles souples en V pourraient être remplacées par un bourrelet avantageusement creux, formant le bord latéral du rideau 4.The curtain 4 has lateral parts which slide in the slots 8 of the uprights 1 and 2. In the particular example of FIG. 1, the curtain 4 is flexible and can be lifted up by winding and comprises horizontal reinforcing bars 6 having axial ends 6a which slide in the slots 8 and the curtain has lateral edges 4a which also slide in the slots 8. The curtain 4 may possibly not include reinforcing bars 6. In cases where the curtain 4 is liable to be impacted violent, for example due to handling vehicles, it may be advantageous for the side parts of the curtain which slide in the slots 8 to be adapted to disengage from said slots 8 during a violent impact on the curtain 4, so as to prevent damage to said curtain. Solutions to this problem are given in documents EP-A-0 398 791, EP-A-0 320 350, GB-A-1 597 396, EP-A-0 264 220 and EP-A-0 272 733. In the example shown, the slots 8 are fairly narrow, so that the lateral parts of the curtain slide in said slots 8, with little play, therefore in substantially sealed contact with the front wall 7 on each side of the slot 8 of so as to minimize the passage of air through bay 5. The tightness between the side edges 4a of the curtain and the uprights 1, 2 can be improved by using thickened side edges, such as for example that shown in FIG. 1a. In FIG. 1a, the lateral edge 4a of the curtain is provided with two sheets of elastic flexible material, fixed to the curtain 4 and extending in V towards the outside of the curtain. When the curtain slides in the slots 8 of the uprights 1, 2, the divergent branches of the V rests elastically on the front wall 7, each on one side of the slot 8, providing an excellent seal. The flexible V-shaped sheets could be replaced by an advantageously hollow bead, forming the lateral edge of the curtain 4.

La porte selon l'invention peut être actionnée par des moyens mécaniques ou électromécaniques bien connus dans l'état de l'art. Le rideau 4 peut être relevable de diverses façons et être réalisé de diverses façons sans sortir du cadre de la présente invention, pourvu qu'il comporte des parties latérales coulissant dans les fentes 8. Les figures 2 à 6 donnent quelques exemples non limitatifs qui expliquent quelques modes de levage du rideau.The door according to the invention can be actuated by mechanical or electromechanical means well known in the state of the art. The curtain 4 can be raised in various ways and be produced in various ways without departing from the scope of the present invention, provided that it has lateral parts sliding in the slots 8. Figures 2 to 6 give some non-limiting examples which explain some ways to lift the curtain.

Par exemple, comme représenté schématiquement sur la figure 2, le rideau 4 peut être souple et s'enrouler sur un axe horizontal 11 en partie supérieure de la porte. Dans l'exemple particulier de la figure 2, le rideau 4 comporte des bords latéraux 4a, épaissis ou non, qui coulissent dans les fentes 8 des montants latéraux 1 et 2. Comme il a déjà été dit précédemment, le rideau 4 pourrait aussi comporter des barres horizontales de renforcement dont les extrémités coulissent ou non dans les fentes 8.For example, as shown schematically in Figure 2, the curtain 4 can be flexible and wind on a horizontal axis 11 in the upper part of the door. In the particular example of FIG. 2, the curtain 4 has lateral edges 4a, thickened or not, which slide in the slots 8 of the lateral uprights 1 and 2. As has already been said previously, the curtain 4 could also include horizontal reinforcing bars, the ends of which slide or not in the slots 8.

Selon un autre exemple représenté schématiquement sur la figure 3, le rideau 4 peut se replier en accordéon. Dans l'exemple particulier de la figure 3, le rideau 4 est constitué de panneaux rigides 14 qui sont articulés sur des barres horizontales de renforcement 6, dont une sur deux coulisse dans les fentes 8 des montants 1, 2. La porte comporte en outre des sangles verticales 12, attachées à la barre de renforcement 6b la plus basse, et adaptées à s'enrouler sur un axe horizontal (non représenté) en partie supérieure de la porte. La barre de renforcement 6c la plus haute (non visible sur la figure 3) est fixe, de façon à ne pas tomber lorsque le rideau 4 est descendu en position fermée. L'enroulement des sangles 12 provoque la remontée de la barre inférieure 6b qui entraîne avec elle les autres barres de renforcement 6 qui coulissent dans les fentes 8, en pliant le rideau 4 en accordéon. Les panneaux rigides 14 peuvent être des panneaux séparés les uns des autres, articulés sur les barres 6, ou encore être formés par une seule toile souple ou une feuille de matériau souple commune à tout le rideau 4 et tendue par des entretoises entre les barres 6.According to another example shown schematically in Figure 3, the curtain 4 can be folded in accordion. In the particular example of FIG. 3, the curtain 4 consists of rigid panels 14 which are articulated on horizontal reinforcing bars 6, one of two of which slides in the slots 8 of the uprights 1, 2. The door further comprises vertical straps 12, attached to the lowest reinforcing bar 6b, and adapted to be wound on a horizontal axis (not shown) in the upper part of the door. The highest reinforcing bar 6c (not visible in FIG. 3) is fixed, so as not to fall when the curtain 4 is lowered into the closed position. The winding of the straps 12 causes the lower bar 6b to rise, which brings with it the other reinforcing bars 6 which slide in the slots 8, by folding the curtain 4 in accordion. The rigid panels 14 can be panels separated from each other, articulated on the bars 6, or even be formed by a single flexible canvas or a sheet of flexible material common to the entire curtain 4 and stretched by spacers between the bars 6 .

Selon un autre exemple représenté schématiquement sur la figure 4, le rideau 4 est constitué par une paroi souple dotée de barres de renforcement horizontales 6 dont une sur deux coulisse dans les fentes 8 des montants 1, 2. Comme dans l'exemple de la figure 3, la barre la plus basse 6b est liée à des sangles 12 qui s'enroulent sur un axe 13 en partie supérieure de la porte. L'enroulement des sangles 12 sur l'axe 13 provoque la remontée de la barre inférieure 6b, qui entraîne avec elle les autres barres de renforcement 6 qui coulissent dans les fentes 8, en pliant le rideau 4 en accordéon. La partie supérieure 4b du rideau est bien entendu fixe, afin de ne pas tomber quand le rideau 4 est descendu en position fermée. On notera que dans cet exemple, il serait éventuellement possible que toutes les barres de renforcement 6 coulissent dans les fentes 8.According to another example shown diagrammatically in FIG. 4, the curtain 4 is constituted by a flexible wall provided with horizontal reinforcing bars 6, one in two of which slides in the slots 8 of the uprights 1, 2. As in the example of the Figure 3, the lowest bar 6b is linked to straps 12 which are wound on an axis 13 in the upper part of the door. The winding of the straps 12 on the axis 13 causes the lower bar 6b to rise, which brings with it the other reinforcing bars 6 which slide in the slots 8, by folding the curtain 4 in accordion. The upper part 4b of the curtain is of course fixed, so as not to fall when the curtain 4 is lowered into the closed position. It will be noted that in this example, it would possibly be possible for all the reinforcement bars 6 to slide in the slots 8.

Dans les exemples des figures 3 et 4, il est souhaitable que le bord latéral 4a du rideau soit à une très faible distance de la paroi frontale 7 du profilé 27 proche du mur 9, de façon que le bord latéral 4a soit sensiblement en contact étanche avec le profilé 27, au moins lorsque le rideau est baissé, pour minimiser les passages d'air au travers de la baie 5. Avantageusement,le bord 4a du rideau peut comporter une bande de matériau souple, telle qu'une bande de caoutchouc éventuellement fendue dans le sens de la larguer, qui s'appuie élastiquement contre la paroi frontale 10 du profilé 27. Des exemples de bandes souples de rideau sont donnés dans le document EP-A-0 194 494 du demandeur et dans le brevet américain correspondant US-A-4 934 437.In the examples of FIGS. 3 and 4, it is desirable that the lateral edge 4a of the curtain is at a very small distance from the front wall 7 of the profile 27 close to the wall 9, so that the lateral edge 4a is substantially in sealed contact with the profile 27, at least when the curtain is lowered, in order to minimize the air passages through the opening 5. Advantageously, the edge 4a of the curtain can comprise a strip of flexible material, such as a rubber strip possibly slotted in the direction of the release, which bears elastically against the front wall 10 of the profile 27. Examples of flexible curtain strips are given in document EP-A-0 194 494 of the applicant and in the corresponding American patent US -A-4 934 437.

Le rideau 4 peut encore être réalisé différemment. Par exemple, comme représenté sur la figure 5, il peut être relevable sans pliage en accordéon ni enroulement, mais par simple translation vers le haut, éventuellement avec une certaine inclinaison par rapport à la verticale. Sur la figure 5, les montants 1, 2 sont ainsi prolongés par des glissières inclinées 15, 16. Le rideau 4 peut alors être souple, renforcé ou non par des barres d'armature horizontale, ou encore constitué de panneaux rigides articulés, etc. Si les glissières de guidage 15, 16 sont dans l'alignement des montants latéraux 1, 2, le rideau 4 pourrait même être constitué d'un seul panneau rigide.The curtain 4 can still be produced differently. For example, as shown in Figure 5, it can be lifted without folding accordion or winding, but by simple translation upwards, possibly with a certain inclination relative to the vertical. In FIG. 5, the uprights 1, 2 are thus extended by inclined slides 15, 16. The curtain 4 can then be flexible, reinforced or not by horizontal reinforcing bars, or even made up of rigid articulated panels, etc. If the guide rails 15, 16 are in alignment with the lateral uprights 1, 2, the curtain 4 could even consist of a single rigid panel.

Selon une autre variante, le rideau 4 peut être constitué de panneaux rigides 17 indépendants, qui sont empilés en partie haute de la porte lorsque le rideau 4 est relevé, comme représenté sur la figure 6.According to another variant, the curtain 4 can be made up of independent rigid panels 17, which are stacked in the upper part of the door when the curtain 4 is raised, as shown in FIG. 6.

Sur la figure 7, on a représenté le montant 1 de la figure 1, avec un rideau 4 à bord épaissi 4a qui coulisse dans la fente 8, en séparant deux volumes d'air à des températures différentes T1 et T2. Du fait qu'il existe une ouverture 34 entre les branches du U, qui sépare les deux profilés 26, 27, le seul échange thermique possible entre les deux masses d'air à T1 et T2 se fait par conduction au travers du profilé 27 en L, sans aucun effet d'ailette puisqu'un côté du profilé 27 est en contact avec le mur 9 et avec la masse d'air à T2 tandis que l'autre côté est en contact avec la masse d'air à T1 : les échanges thermiques se font donc au travers d'une surface beaucoup plus limitée que dans l'art antérieur, où le montant comporte généralement une paroi arrière à la place de l'ouverture 34 de sorte que le montant forme une ailette de dissipation de la chaleur.In Figure 7, there is shown the amount 1 of Figure 1, with a curtain 4 with thickened edge 4a which slides in the slot 8, separating two volumes of air at different temperatures T1 and T2. Because there is an opening 34 between the branches of the U, which separates the two sections 26, 27, the only possible heat exchange between the two air masses at T1 and T2 is by conduction through the section 27 in L, without any fin effect since one side of the profile 27 is in contact with the wall 9 and with the air mass at T2 while the other side is in contact with the air mass at T1: the heat exchanges are therefore made through a much more limited surface than in the prior art, where the upright generally has a rear wall in place of the opening 34 so that the upright forms a fin for dissipating heat .

En outre, la section en U du montant des figures 1 et 7 permet aisément de nettoyer le montant sensiblement intégralement, ce qui est très important dans tous les lieux où doit être maintenue une hygiène stricte, par exemple les entrepôts frigorifiques pour produits alimentaires, les laboratoires pharmaceutiques, etc.. En particulier, la paroi frontale 7 qui est proche de la baie 5 et donc qui est susceptible d'entrer en contact avec des objets ou des personnes traversant la baie 5, peut être nettoyée sur ses deux faces : sur un premier côté 7a dirigé vers le rideau 4, et sur un second côté 7b opposé au rideau 4, du fait que ces deux côtés sont accessibles facilement. Le côté 7b est accessible par l'ouverture 34 du montant, entre les deux parois latérales 10. Ainsi, les profilés des montants 1 et 2 peuvent être nettoyés sur leurs deux faces. La section en U des montants, comme d'ailleurs d'autres sections profilées, permet de leur donner une bonne résistance mécanique.In addition, the U-shaped section of the upright in Figures 1 and 7 makes it easy to clean the upright substantially entirely, which is very important in all places where strict hygiene must be maintained, for example cold stores for food, pharmaceutical laboratories, etc. In particular, the front wall 7 which is close to the bay 5 and therefore which is likely to come into contact with objects or people crossing the bay 5, can be cleaned on both sides: a first side 7a directed towards the curtain 4, and on a second side 7b opposite the curtain 4, because these two sides are easily accessible. The side 7b is accessible through the opening 34 of the upright, between the two side walls 10. Thus, the profiles of the uprights 1 and 2 can be cleaned on their two faces. The U-shaped section of the uprights, like other profiled sections, gives them good mechanical resistance.

Comme représenté sur la figure 1, les parois 10 de chaque montant peuvent comporter une échancrure 35 en partie basse, pour faciliter le nettoyage à la lance.As shown in Figure 1, the walls 10 of each upright may have a notch 35 in the lower part, to facilitate cleaning with a lance.

Les montants 1 et 2 peuvent aussi avoir d'autres sections qu'une section en U ayant des parois planes. Par exemple, la figure 8 représente une variante du montant de la figure 7, ayant toujours une section sensiblement en forme de U, mais avec une paroi frontale 7 arrondie. En outre, dans l'exemple de la figure 8, la paroi 7 comporte deux lèvres 18a, 18b qui délimitent latéralement la fente 8. Ces lèvres 18a, 18b s'étendent sur la hauteur de la fente 8, et s'étendent sur une courte distance horizontale, parallèlement au rideau 4, vers ledit rideau ou en s'éloignant dudit rideau. De telles lèvres peuvent être avantageuses dans certains cas, pour éviter d'endommager par frottement localisé les parties latérales qui coulissent dans les fentes 8 des montants latéraux. Leur largeur est faible, de sorte qu'elles peuvent être nettoyées aisément.The uprights 1 and 2 can also have other sections than a U-shaped section having planar walls. For example, Figure 8 shows a variant of the upright of Figure 7, still having a substantially U-shaped section, but with a rounded front wall 7. In addition, in the example of FIG. 8, the wall 7 comprises two lips 18a, 18b which laterally delimit the slot 8. These lips 18a, 18b extend over the height of the slot 8, and extend over a short horizontal distance, parallel to the curtain 4, towards said curtain or away from said curtain. Such lips can be advantageous in certain cases, to avoid damaging by localized friction the lateral parts which slide in the slots 8 of the lateral uprights. Their width is small, so that they can be easily cleaned.

La figure 9 représente une autre variante de la section de la figure 8, mais avec une paroi 7 à section en V.FIG. 9 represents another variant of the section of FIG. 8, but with a wall 7 with a V section.

La figure 10 représente une autre variante, dans laquelle les montants latéraux comportent seulement une paroi 7 en forme de V. La figure 11 représente une variante de la figure 8, dans laquelle les lèvres 18a, 18b planes sont remplacées par des parties arrondies 19a, 19b. On notera d'ailleurs d'une manière générale que les bords latéraux longitudinaux de la fente 8 peuvent être dotés d'un revêtement protecteur, par exemple anti-friction, sans sortir du cadre de la présente invention.FIG. 10 represents another variant, in which the lateral uprights only have a V-shaped wall 7. FIG. 11 represents a variant of FIG. 8, in which the flat lips 18a, 18b are replaced by rounded parts 19a, 19b. It will also be noted in general that the longitudinal lateral edges of the slot 8 can be provided with a protective coating, for example anti-friction, without departing from the scope of the present invention.

Dans l'exemple de la figure 12, le montant latéral a une section en H dans laquelle la paroi 7 ayant le fente 8 s'étend entre deux parois d'ailes 20 parallèles au rideau, les parois d'aile 20 s'étendant à la fois vers le rideau 4 et vers l'extérieur de la baie 5 à partir de la paroi frontale 7. Un tel montant à section en H peut être éventuellement formé par deux profilés à section en U assemblés, ou encore par quatre cornières assemblées 30, 31, 32, 33, comme représenté sur la figure 12a.In the example of FIG. 12, the lateral upright has an H section in which the wall 7 having the slot 8 extends between two wing walls 20 parallel to the curtain, the wing walls 20 extending at both towards the curtain 4 and towards the outside of the opening 5 from the front wall 7. Such an upright with an H-section can possibly be formed by two U-shaped section profiles assembled, or by four assembled angles 30, 31, 32, 33, as shown in FIG. 12a.

Selon une autre variante, représenté sur la figure 13, la section des montants latéraux 1, 2 a une forme de U ayant une base 22 et deux branches 21, mais la fente 8 est formée dans une paroi 7 qui représente une des branches 21 du U.According to another variant, represented in FIG. 13, the section of the lateral uprights 1, 2 has a U shape having a base 22 and two branches 21, but the slot 8 is formed in a wall 7 which represents one of the branches 21 of the U.

On notera que les sections des montants des figures 7 à 13 peuvent avantageusement être utilisées même lorsque la porte sépare deux masses d'air de températures identiques ou peu différents, mais dans des lieux où une hygiène stricte doit être maintenue. Dans ce cas, il n'est pas forcément nécessaire d'avoir un contact étanche entre le montant et le mur autour de la baie, et entre le rideau et le montant, sauf si la porte doit interdire les passages d'air pour d'autres raisons (local stérile ou sans poussière, local en surpression, ...)It will be noted that the sections of the uprights of FIGS. 7 to 13 can advantageously be used even when the door separates two air masses of identical or little different temperatures, but in places where strict hygiene must be maintained. In this case, it is not necessarily necessary to have a tight contact between the upright and the wall around the opening, and between the curtain and the upright, unless the door must prevent air passages to other reasons (sterile or dust-free room, overpressure room, ...)

Dans la forme de réalisation de la figure 12a, les deux cornières 32, 33 plus proches du rideau peuvent éventuellement être réalisées en matière plastique, et les deux autres cornières 30, 31 en acier. On favorise ainsi le glissement du rideau, et on limite les dégâts causés par des chocs d'engins de manutention sur les montants, tout en limitant les échanges thermiques.In the embodiment of Figure 12a, the two angles 32, 33 closer to the curtain may optionally be made of plastic, and the other two angles 30, 31 of steel. This favors the sliding of the curtain, and we limit the damage caused by shocks from handling equipment on the uprights, while limiting heat exchange.

Les montants 1, 2 peuvent aussi être réalisés en une seule pièce, comme représenté sur la figure 14, auquel cas la fente 8 est découpée dans la paroi frontale 7. La fente 8 peut éventuellement déboucher en partie haute de la paroi 7 par exemple si le rideau 4 se relève par enroulement, mais ladite fente 8 peut aussi ne pas déboucher en partie haute de la paroi 7, comme représenté sur la figure 14, par exemple dans le cas où le rideau 4 se relève par pliage en accordéon. Dans la forme de réalisation de la figure 14, le montant comporte deux parois 10 parallèles au rideau 4 : ces parois 10 peuvent éventuellement être reliées l'une à l'autre par des entretoises pour renforcer le montant.The uprights 1, 2 can also be produced in a single piece, as shown in FIG. 14, in which case the slot 8 is cut in the front wall 7. The slot 8 can possibly open out in the upper part of the wall 7 for example if the curtain 4 is raised by winding, but said slot 8 may also not open into the upper part of the wall 7, as shown in Figure 14, for example in the case where the curtain 4 is raised by folding accordion. In the embodiment of Figure 14, the amount has two walls 10 parallel to the curtain 4: these walls 10 may optionally be connected to each other by spacers to strengthen the amount.

Les montants latéraux 1, 2 peuvent aussi être réalisés en deux pièces assemblées 26, 27, qui délimitent chacune un bord longitudinal de la fente 8. Sur l'exemple de la figure 15, les deux pièces 26, 27 sont des cornières à section en L et sont assemblées par des plaques entretoises ou platines 22, 23 horizontales, éventuellement associées à des renforts d'angle 24. La platine supérieure 23 peut éventuellement comporter une découpe 28 en correspondance avec la fente 8 pour permettre à ladite fente 8 de déboucher en partie supérieure du montant. Les platines 22, 23 peuvent être soudées, rivées, boulonnées, ou fixées par tout autre moyen. Les platines 22, 23 peuvent éventuellement être réalisées en deux parties, comme sur la figure 18.The lateral uprights 1, 2 can also be produced in two assembled pieces 26, 27, which each delimit a longitudinal edge of the slot 8. In the example of FIG. 15, the two pieces 26, 27 are angle sections with a cross section L and are assembled by horizontal spacer plates or plates 22, 23, possibly associated with corner reinforcements 24. The upper plate 23 may optionally include a cutout 28 in correspondence with the slot 8 to allow said slot 8 to open into upper part of the upright. The plates 22, 23 can be welded, riveted, bolted, or fixed by any other means. The plates 22, 23 can optionally be produced in two parts, as in FIG. 18.

La figure 16 représente une autre variante de l'invention, dans laquelle le relevage du rideau se fait par pliage en accordéon comme sur les figures 3 et 4, mais où les montants latéraux ont une forme de U avec les branches du U tournées vers l'intérieur de la baie 5. Une des branches du U est en contact étanche contre le mur 9, et comme on le voit sur les figures 17 et 18, cette branche du U comporte sur toute sa hauteur une fente verticale 36 qui sépare le montant en deux profilés 26, 27, comme on l'a vu précédemment. Lorsque le rideau 4 est baissé, il est appliqué en contact sensiblement étanche contre le profilé 27 au moyen d'un organe applicateur 38, tel que celui représenté sur la figure 18a, qui a la forme d'un corps allongé en matière plastique, monté par une articulation élastique 39 sur le profilé 26. Un tel organe applicateur est décrit avec plus de détail dans le document EP-A-0 416 961 du demandeur ou dans le brevet correspondant US-A-5 095 964.FIG. 16 represents another variant of the invention, in which the curtain is raised by accordion folding as in FIGS. 3 and 4, but where the lateral uprights have a U shape with the branches of the U facing towards the inside the bay 5. One of the branches of the U is in tight contact against the wall 9, and as can be seen in FIGS. 17 and 18, this branch of the U has over its entire height a vertical slot 36 which separates the upright into two sections 26, 27, as seen previously. When the curtain 4 is lowered, it is applied in substantially sealed contact against the profile 27 by means of an applicator member 38, such as that shown in FIG. 18a, which has the shape of an elongated plastic body, mounted by an elastic articulation 39 on the profile 26. Such an applicator member is described in more detail in document EP-A-0 416 961 of the applicant or in the corresponding patent US-A-5 095 964.

D'autre organes applicateurs peuvent être envisagés.Other applicator members can be envisaged.

Le bord 4a du rideau pourrait éventuellement comporter des bandes souples frottant sur la base du profil en U, telles que celles représentées sur la figure 19, et décrites dans le document EP-A-0 194 194 du demandeur et dans le brevet américain correspondant US-A-4 934 437.The edge 4a of the curtain could possibly include flexible bands rubbing on the base of the U-shaped profile, such as those shown in FIG. 19, and described in document EP-A-0 194 194 of the applicant and in the corresponding American patent US -A-4 934 437.

Avantageusement, les profilés 26 et 27 comportent en partie haute et en partie basse, des platines constituées de deux plaques qui ne sont pas en contact direct l'une avec l'autre. La figure 18 représente la platine inférieure 22, constituée de deux plaques 22a, 22b qui resposent sur le sol et sont séparés l'une de l'autre par une fente 22c. La platine 22a est soudée au profilé 27 sur tout le profil de ce profilé et au profilé 26 sur une faible longueur du profil du profilé 26. La plaque 22b est soudée à la longueur restante du profil du profilé 26. Les plaques 22a et 22b sont découpées en suivant sensiblement le profil des profilés 26 et 27, de façon à avoir des dimensions minimales desdites plaques pour limiter les échanges thermiques. La plaque 22a constitue un organe de liaison entre les deux profilés 26 et 27. Grâce à la fente 22c et à la faible largeur de la plaque 22a, ladite plaque constitue un pont thermique très limité entre les profilés 26 et 27. La plaque 22b sert à rigidifier le profilé 26 et à améliorer son assise sur le sol.Advantageously, the sections 26 and 27 comprise, in the upper part and in the lower part, plates made up of two plates which are not in direct contact with each other. Figure 18 shows the lower plate 22, consisting of two plates 22a, 22b which lie on the ground and are separated from each other by a slot 22c. The plate 22a is welded to the profile 27 over the entire profile of this profile and to the profile 26 over a short length of the profile of the profile 26. The plate 22b is welded to the remaining length of the profile of the profile 26. The plates 22a and 22b are cut substantially following the profile of profiles 26 and 27, so as to have minimum dimensions of said plates to limit heat exchange. The plate 22a constitutes a connecting member between the two profiles 26 and 27. Thanks to the slot 22c and the small width of the plate 22a, said plate constitutes a very limited thermal bridge between the profiles 26 and 27. The plate 22b serves to stiffen the profile 26 and improve its seat on the ground.

Les figures 19 et 20 représentent une variante du montant de la figure 18, plus spécialement destiné aux cas où ledit montant est situé d'un côté du mur 9 qui est à une température T2 inférieure à 0°C, tandis que l'autre côté du mur 9 est à une température T1 supérieure à 0°C. Dans cette variante, l'intérieur de la section en U du montant est revêtu d'une garniture isolante 40, qui a pour but en particulier d'éviter la formation de givre. La garniture 40 peut avantageusement être dotée de moyens de chauffage, tels que par exemple de fils électriques résistifs 41. Une telle garniture existante et ses moyens de chauffage sont décrits par exemple dans le document EP-A-0 220 096 du demandeur et dans le brevet américain correspondant US-A- 4 776 379. Avantageusement, les bords latéraux 4a du rideau sont dotés de bandes souples isolantes 42, par exemple en caoutchouc, qui frottent sur la base de la section en U du montant : de telles bandes isolantes sont décrites plus en détail dans le document EP-A- 0 194 194 du demandeur et dans le brevet américain correspondant US-A-4 934 437. Eventuellement, dans la forme de réalisation des figures 19 et 20, le montant pourrait ne pas comporter d'organe applicateur 38, le rideau 4 étant en contact étanche avec le profilé 27 par l'intermédiaire des bandes souples 42 et de la garniture isolante 40.Figures 19 and 20 show a variant of the amount of Figure 18, more especially intended for cases where said amount is located on one side of the wall 9 which is at a temperature T2 lower than 0 ° C, while the other side of wall 9 is at a temperature T1 greater than 0 ° C. In this variant, the interior of the U-shaped section of the upright is coated with an insulating lining 40, which aims in particular to avoid the formation of frost. The lining 40 can advantageously be provided with heating means, such as for example resistive electrical wires 41. Such an existing lining and its heating means are described for example in document EP-A-0 220 096 of the applicant and in Corresponding American patent US-A-4,776,379. Advantageously, the lateral edges 4a of the curtain are provided with flexible insulating bands 42, for example of rubber, which rub on the base of the U-section of the upright: such bands insulators are described in more detail in document EP-A-0 194 194 of the applicant and in the corresponding American patent US-A-4,934,437. Optionally, in the embodiment of FIGS. 19 and 20, the amount may not have an applicator member 38, the curtain 4 being in leaktight contact with the profile 27 by means of the flexible strips 42 and the insulating lining 40.

Avantageusement, au moins la platine inférieure 22 est recouverte d'une plaque isolante 43, dotée d'une pente vers l'extérieiur du U, c'est-à-dire vers la baie 5, représentée par les flèches 44 sur la figure 19 afin d'évacuer hors du montant l'eau de condensation ou de dégivrage, ou l'eau provenant du nettoyage de l'intérieur du montant. Avantageusement, la plaque 43 comporte des moyens de chauffage 45, par exemple des résistances électriques chauffantes noyées dans la plaque 43 si celle-ci est en matière plastique : on évite ainsi la formation de givre sur la plaque 43.Advantageously, at least the lower plate 22 is covered with an insulating plate 43, having a slope towards the outside of the U, that is to say towards the opening 5, represented by the arrows 44 in FIG. 19 in order to evacuate condensation or defrost water, or water from cleaning inside the upright, outside the upright. Advantageously, the plate 43 includes heating means 45, for example electric heating resistors embedded in the plate 43 if the latter is made of plastic: this prevents the formation of frost on the plate 43.

Dans la description qui précède et les révendications, il est fait mention uniquement d'une porte à rideau relevable, mais l'invention peut éventuellement aussi s'appliquer aux glissières horizontales des portes ayant un rideau déplaçable horizontalement.In the foregoing description and the claims, mention is made only of a liftable curtain door, but the invention may possibly also apply to horizontal runners of doors having a curtain that can be moved horizontally.
