Description

La présente invention a pour objet un rideau souple étanche pour porte accordéon.The present invention relates to a flexible waterproof curtain for an accordion door.

Il est connu de réaliser des portes accordéon à rideau souple. Une porte de ce type comporte usuellement un rideau souple de matière plastique armée, rigidifié à intervalles réguliers par des barres d'armature et guidé sur ses bords latéraux dans ses mouvements ascendants et descendants par des profilés un U verticaux. Les barres d'armature portent généralement des galets à leurs extrémités, qui facilitent le repli ou le déploiement du rideau. La porte est actionnée par un moteur qui entraîne en rotation un arbre sur lequel est assujettie l'extrémité supérieure de sangles, lesquelles sont, d'autre part, fixées a la barre inférieure et maintenues au niveau de certaines autres barres par des guides.It is known to produce accordion doors with a flexible curtain. A door of this type usually comprises a flexible curtain of reinforced plastic, stiffened at regular intervals by rebar and guided on its lateral edges in its upward and downward movements by vertical U sections. Reinforcement bars generally have rollers at their ends, which facilitate the folding or unfolding of the curtain. The door is actuated by a motor which rotates a shaft on which is secured the upper end of straps, which are, on the other hand, fixed to the lower bar and held at the level of certain other bars by guides.

Une porte comme celle qui vient d'être décrite n'est pas étanche pour deux raisons. D'une part, lorsque les barres d'armature sont munies de galets à leurs extrémités, les bords latéraux du rideau souple sont distants du fond des profilés en U d'au moins la longueur de ces galets. Un interstice se trouve ainsi ménagé au niveau des bords latéraux de la porte, sur toute sa hauteur, par lequel des échanges thermiques entre intérieur et extérieur peuvent se produire. D'autre part, le rideau souple n'est pas maintenu latéralement par les profilés en U de façon étanche, les montants parallèles desdits profilés étant écartés au moins de l'épaisseur des plis que forme le rideau quand la porte est totalement ouverte. Cet écartement est donc relativement important par rapport à l'épaisseur qu'a le rideau quand, la porte étant fermée, il est totalement déployé. Dans cette dernière configuration, le rideau a un certain jeu latéral ; il peut battre au gré des vents s'exerçant sur sa surface extérieure ou des surpressions s'exerçant sur sa surface intérieure.A door like the one just described is not waterproof for two reasons. On the one hand, when the reinforcing bars are provided with rollers at their ends, the lateral edges of the flexible curtain are distant from the bottom of the U-shaped profiles at least the length of these rollers. A gap is thus formed at the side edges of the door, over its entire height, through which heat exchanges between inside and outside can occur. On the other hand, the flexible curtain is not held laterally by the U-shaped profiles in leaktight fashion, the parallel uprights of said profiles being spaced at least by the thickness of the folds that the curtain forms when the door is fully open. This spacing is therefore relatively large compared to the thickness of the curtain when, the door being closed, it is fully deployed. In this latter configuration, the curtain has a certain lateral clearance; it can beat with the winds exerted on its external surface or overpressures exerted on its internal surface.

Pour résoudre le problème que pose l'étanchéïté des portes accordéon, plusieurs solutions ont été envisagées jusqu'à présent. On a, par exemple, imaginé de fixer, à l'intérieur et sur toute la hauteur de l'un ou des deux montants parallèles du profilé en U"une brosse à poils obliques dans le plan horizontal et tournés vers 1e centre de la porte. On a représenté sur les figures 1,2 et 3 la vue en coupe schématique, selon un plan horizontal, de trois profilés en U 1, comportant respectivement une brosse 2 fixée sur le montant extérieur, une brosse 3 fixée sur le montant intérieur, une brosse 2', 3', fixée sur chaque montant. Les brosses utilisées sont à poils souples et assurent une bonne étanchéïté en s'écrasant sur le rideau souple, pourvu que ledit rideau soit plaqué contre eux, ce qui ne se produit que dans le cas d'un vent suffisamment fort (figures 2 et 3) ou dans le cas .d'une surpression intérieure assez importante (figures 1. et 3). Ces conditions sont rarement réalisées, au moins de façon continue. Quant à utiliser, dans la configuration représentée sur la figure 3, des brosses à poils suffisamment longs pour qu'ils fassent constamment et simultanément pression sur la surface intérieure et sur la surface extérieure du rideau, cela est impossible puisque le rideau n'aurait plus la place de se plier en accordéon lors de l'ouverture de la porte.To solve the problem posed by the tightness of accordion doors, several solutions have been considered so far. One has, for example, imagined to fix, inside and over the entire height of one or two parallel uprights of the U-profile " a brush with oblique bristles in the horizontal plane and turned towards the center of the door FIGS. 1, 2 and 3 show the schematic sectional view, along a horizontal plane, of three U-shaped sections 1, respectively comprising a brush 2 fixed to the external upright, a brush 3 fixed to the internal upright, a brush 2 ', 3', fixed on each upright. The brushes used are flexible bristles and ensure a good sealing by crushing on the flexible curtain, provided that said curtain is pressed against them, which occurs only in in the case of a sufficiently strong wind (Figures 2 and 3) or in the case of a fairly significant internal overpressure (Figures 1. and 3 ). These conditions are rarely realized, at least continuously. in the configuration shown in FIG. 3, sufficiently bristled brushes long so that they constantly and simultaneously apply pressure to the interior and exterior surfaces of the curtain, this is impossible since the curtain would no longer have the space to fold in an accordion when the door is opened.

Une autre solution, décrite dans le brevet français n°83 10970, consiste à équiper l'un des montants de chacun des deux profilés en U d'un dispositif d'étanchéïté mobile venant s'appliquer automatiquement sur les bords latéraux du rideau souple à la fermeture totale de la porte, le plaquant ainsi contre l'autre montant de chacun desdits profilés, lesquels peuvent comporter avantageusement une brosse similaire à celles décrites plus haut. Ce dispositif permet de réaliser une bonne étanchéïté. Cependant, il est un peu lourd, et par conséquent coûteux. Une caractéristique commune à tous ces dispositifs d'étanchéité, exception faite du dernier cité, est que, étant fixes, -qu'ils soient installés sur l'un ou sur les deux montants parallèles des profilés en U-, ils doivent agir sur un rideau mobile ; d'où leur efficacité restreinte.Another solution, described in French patent n ° 83 10970, consists in equipping one of the uprights of each of the two U-shaped profiles with a mobile sealing device which is applied automatically to the lateral edges of the flexible curtain to closing the door completely, thereby pressing it against the other upright of each of said sections, which may advantageously include a brush similar to those described above. This device makes it possible to achieve a good seal. However, it is a bit heavy, and therefore expensive. A characteristic common to all these sealing devices, with the exception of the last mentioned, is that, being fixed, -whether they are installed on one or on the two parallel uprights of the U-shaped profiles, they must act on a movable curtain; hence their limited effectiveness.

L'objet de la présente invention est d'éliminer cette caractéristique désavantageuse en dotant la porte accordéon d'un organe d'étanchéité mobile, non pas fixé sur les profilés en U, comme le dispositif décrit dans le brevet cité plus haut, mais assujetti au rideau souple lui-même. Le rideau souple selon l'invention comporte, sur chacun de ses bords latéraux, une bande d'un matériau souple susceptible de s'appliquer contre le fond du montant ou de la glissière quand le rideau est descendu. Dans le cas où certaines barres d'armature sont munies de galets de guidage à leurs extrémités, la bande de matériau souple peut être interrompue au niveau des galets, et doit, de toute façon, être plus large que la longueur axiale des galets, afin de ne pas être écartée du fond de la glissière par ceux-ci. Dans le cas où les barres d'armature ne comportent pas de galets et où elles ne pénètrent dans les profilés en U que sur une partie de la profondeur desdits profilés, les bandes d'étanchéïté peuvent être constituées par les bords du rideau lui-même, ledit rideau étant plus large que la distance séparant le fond des profilés.The object of the present invention is to eliminate this disadvantageous characteristic by providing the accordion door with a movable sealing member, not fixed to the U-shaped profiles, like the device described in the patent cited above, but subject to the flexible curtain itself. The flexible curtain according to the invention comprises, on each of its lateral edges, a strip of flexible material capable of being applied against the bottom of the upright or of the slide when the curtain is lowered. In the case where certain reinforcing bars are provided with guide rollers at their ends, the strip of flexible material can be interrupted at the level of the rollers, and must, in any case, be wider than the axial length of the rollers, in order not to be removed from the bottom of the slide by them. In the case where the reinforcing bars do not have rollers and where they penetrate into the U-profiles only over part of the depth of said profiles, the sealing strips can be formed by the edges of the curtain itself , said curtain being wider than the distance separating the bottom of the profiles.

D'autres caractéristiques et avantages de la présente invention apparaîtront mieux à la lecture de la description suivante faite en relation avec les dessins annexés, sur lesquels:

  • la figure 4 représente une vue en perspective schématique, comportant un arraché, d'une porte accordéon munie d'un organe d'étanchéïté selon l'invention;
  • la figure 5 est une vue en coupe schématique d'un mode de réalisation de l'invention, selon un plan horizontal passant entre deux barres d'armature d'un profilé en U;

  • la figure 7 est une vue en perspective schématique partielle d'encore un autre mode de réalisation de l'invention.
Other characteristics and advantages of the present invention will appear better on reading the following description made in relation to the appended drawings, in which:
  • FIG. 4 represents a schematic perspective view, comprising a cutaway, of an accordion door provided with a sealing member according to the invention;
  • Figure 5 is a schematic sectional view of an embodiment of the invention, along a horizontal plane passing between two reinforcing bars of a U-shaped section;
  • Figure 6 is a schematic sectional view of another embodiment of the invention, along a horizontal plane passing between two reinforcing bars of a U-shaped section; and,
  • Figure 7 is a partial schematic perspective view of yet another embodiment of the invention.

Sur la figure 4, on reconnaît les éléments essentiels constituant une porte accordéon : profilés en U 1 verticaux, reliés à leur extrémité supérieure par une poutre transversale 4 ; moteur 5 entraînant un arbre 6 d'enroulement des sangles de levage 7 ; rideau souple 8 rigidifié à intervalles réguliers par des barres d'armature 9 logées dans des fourreaux fixés audit rideau ; guides 10 des sangles de levage 7 fixés sur certaines barres d'armature 9 ; galets 11 fixés aux extrémités des barres d'armature 9. La porte accordéon représentée sur la figure 4 comporte en outre un organe d'étanchéïté selon l'invention. Cet organe d'étanchéïté se compose de deux bandes 12 de matériau souple fixées respectivement sur chacun des bords latéraux du rideau souple, interrompues ou non au niveau de chaque galet 11 et suffisamment larges pour entrer en contact avec le fond des profilés en U 1. Ces bandes 12 ont donc une largeur supérieure à la longueur des galets 11. Elles peuvent être constituées par un ruban de caoutchouc continu ou comportant des entailles dans le sens de la largeur ; par l'empilage et l'asssemblage d'au moins deux de ces rubans entaillés, les entailles étant avantageusement décalées les unes par rapport aux autres ; par une brosse à poils longs et souples (cas des figures 4 et 5) ou par tout autre matériau souple, sous quelque forme que ce soit, susceptible d'assurer les mêmes fonctions. Dans un mode de réalisation de l'invention représenté sur les figures 4 et 5, on utilise des bandes 12 formées de brosses à poils longs et souples qui présentent l'intérêt d'assurer une bonne étanchéïté pour un frottement réduit sur le fond du profi lé.In FIG. 4, the essential elements constituting an accordion door are recognized: vertical U-shaped profiles 1, connected at their upper end by a transverse beam 4; motor 5 driving a shaft 6 for winding the lifting straps 7; flexible curtain 8 stiffened at regular intervals by rebar 9 housed in sleeves fixed to said curtain; guides 10 of the lifting straps 7 fixed on certain rebar 9; rollers 11 fixed to the ends of the reinforcing bars 9. The accordion door shown in FIG. 4 further comprises a sealing member according to the invention. This sealing member consists of two strips 12 of flexible material fixed respectively on each of the lateral edges of the flexible curtain, interrupted or not at each roller 11 and sufficiently wide to come into contact with the bottom of the U-shaped profiles 1. These strips 12 therefore have a width greater than the length of the rollers 11. They can be formed by a continuous rubber band or having notches in the width direction; by stacking and assembling at least two of these notched ribbons, the notches being advantageously offset from one another; by a brush with long and flexible bristles (in the case of FIGS. 4 and 5) or by any other flexible material, in any form whatsoever, capable of ensuring the same functions. In one embodiment of the invention shown in FIGS. 4 and 5, strips 12 formed of brushes with long and flexible bristles are used which have the advantage of ensuring good sealing for reduced friction on the bottom of the profile. the.

Dans un autre mode de réalisation représenté sur la figure 6, les bandes souples 12 sont formées par un ruban 15 plié en deux dans le sens de la largeur et dont les bords 16, situés en vis-à-vis, sont appliqués respectivement sur les deux faces d'un bord latéral du rideau souple 8. Eventuellement, on peut placer un boudin 17 de mousse élastique à l'intérieur de l'espace délimité par le pli du ruban 15.In another embodiment shown in FIG. 6, the flexible strips 12 are formed by a ribbon 15 folded in half in the width direction and whose edges 16, located opposite, are applied respectively to the two sides of a lateral edge of the flexible curtain 8. Optionally, a strand 17 of elastic foam can be placed inside the space delimited by the fold of the ribbon 15.

Avec les modes de réalisation de l'invention décrits précédemment, la fixation des bandes 12 sur les bords du rideau 8 peut se faire de différentes façons. On peut coller ou coudre, ou coller et coudre, souder, agrafer chaque partie de bande 12 correspondant à l'intervalle séparant deux barres d'armature sur 1e bord de la surface intérieure ou de la surface extérieure du rideau 8. Si le rideau souple 8 est constitué par l'assemblage de deux feuilles d'un matériau adéquat (toile plastifiée, plastique armé ou autre), il paraît avantageux de placer chaque partie de bande 12 en sandwich entre les bords de deux feuilles et de coudre l'ensemble ensuite. Si la bande est constituée d'un ruban plié en deux dans le sens de la largeur (figure 6), les deux bords du ruban peuvent être cousus avec le bord du rideau, ou agrafés ou collés ou soudés. On peut aussi utiliser une double fixation, par exemple, agrafer et coller.With the embodiments of the invention described above, the fixing of the strips 12 on the edges of the curtain 8 can be done in different ways. We can glue or sew, or glue and sew, weld, staple each strip part 12 corresponding to the interval separating two reinforcing bars on the edge of the inner surface or the outer surface of the curtain 8. If the flexible curtain 8 is constituted by the assembly of two sheets of a suitable material (plasticized canvas, reinforced plastic or other), it seems advantageous to place each strip part 12 in sandwich between the edges of two sheets and to sew the whole then . If the strip consists of a ribbon folded in half across the width (Figure 6), the two edges of the ribbon can be sewn with the edge of the curtain, or stapled or glued or welded. One can also use a double fixing, for example, stapling and gluing.

Dans le mode de réalisation de l'invention représenté sur la figure 7, on prévoit des barres d'armature 9 ne portant pas de galets à leurs extrémités et ne s'engageant dans les profilés en U 1 que sur une partie de la profondeur desdits profilés. Les fourreaux de logement des barres 9 sont alors fermés à une de leurs extrémités. Les barres 9 sont introduites dans lesdits fourreaux par leur extrémité libre, laquelle est fermée ultérieurement par une patte comportant une pression ou, avantageusement, par une pièce collée, ou thermocoilée. Avec un rideau de ce type, les bandes 12 d'étanchéité latérales ne sont plus rapportées comme dans les modes de réalisation précédents mais sont constituées par les bords latéraux du rideau souple 8 lui-même, qu'on prévoit plus large, d'une vingtaine de centimètres environ, que la distance séparant le fond des profilés en U1.In the embodiment of the invention shown in FIG. 7, reinforcing bars 9 are provided, not carrying rollers at their ends and engaging in the U-shaped profiles 1 only over part of the depth of said profiles. The casing housing the bars 9 are then closed at one of their ends. The bars 9 are introduced into said sleeves by their free end, which is closed subsequently by a tab comprising a pressure or, advantageously, by a glued or thermo-bonded part. With a curtain of this type, the lateral sealing strips 12 are no longer attached as in the previous embodiments but are constituted by the lateral edges of the flexible curtain 8 itself, which is provided for wider, of a about twenty centimeters, than the distance between the bottom of the U1 profiles.

La présente invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits ; elle est au contraire susceptible de modifications et variantes qui apparaîtront à l'homme de l'art.The present invention is not limited to the embodiments which have just been described; on the contrary, it is subject to modifications and variants which will appear to those skilled in the art.
