Description

La présente invention se rapporte à une porte souple, c'est-à-dire à une porte comprenant une feuille souple se déroulant verticalement dans le plan d'une ouverture de manière à masquer ou à démasquer celle-ci.The present invention relates to a flexible door, that is to say a door comprising a flexible sheet unwinding vertically in the plane of an opening so as to hide or unmask it.

L'un des buts de la présente invention est de réaliser une porte souple d'une conception simple et qui assure une bonne tension de la bande souple.One of the aims of the present invention is to produce a flexible door of a simple design and which ensures good tension of the flexible strip.

La porte souple, selon l'invention comprend un bâti avec deux guides verticaux pour une barre de seuil sur laquelle est fixée l'une des extrémités d'une feuille souple enroulée sur un tambour horizontal supporté par un châssis monté à l'extrémité supérieure du bâti, ledit tambour étant relié par une liaison cinématique à un moteur pour commander sa rotation dans un sens et dans l'autre en vue de fermer et d'ouvrir la porte et est caractérisée en ce que la feuille souple est constituée par une feuille transparente de chlorure de polyvinyle les guides comportant des interrupteurs de fin de course correspondant, l'un à la position ouverte et, l'autre à la position fermée et coopérant avec la barre de seuil.The flexible door according to the invention comprises a frame with two vertical guides for a threshold bar on which is fixed one of the ends of a flexible sheet wound on a horizontal drum supported by a frame mounted at the upper end of the frame, said drum being connected by a kinematic link to a motor to control its rotation in one direction and in the other in order to close and open the door and is characterized in that the flexible sheet is constituted by a transparent sheet polyvinyl chloride guides having corresponding limit switches, one in the open position and the other in the closed position and cooperating with the threshold bar.

Grâce à cette disposition, on réalise une porte souple transparente, ce qui présente de grands avantages dans de nombreuses applications, utilisant un matériau qui est peu cher, très solide, peu sensible à l'abrasion, qui présente une bonne transparence, la conception de la porte, malgré la faible stabilité du matériau au différence de température assurant une bonne tension de la feuille en position fermée et un relevage toujours correspondant à celui prévu initialement.Thanks to this arrangement, a transparent flexible door is produced, which has great advantages in many applications, using a material which is inexpensive, very solid, not very sensitive to abrasion, which has good transparency, the design of the door, despite the low stability of the material at the temperature difference ensuring good tension of the sheet in the closed position and a lift always corresponding to that initially planned.

Suivant une caractéristique constructive particulière, la barre de seuil est constituée par un profilé à section en H dont l'âme permet la fixation, à ses extrémités, de barrettes solidaires de platines supportant des axes orthogonaux sur lesquels tournent fous des galets de guidage de la barre de seuil dans les guides verticaux.According to a particular constructive characteristic, the threshold bar is constituted by an H-shaped section whose core allows the fixing, at its ends, of bars fixed to plates supporting orthogonal axes on which idle guide rollers of the threshold bar in the vertical guides.

De préférence, le bord supérieur de la barre de seuil comporte une fente rétrécie pour recevoir le bord libre de la feuille qui est solidaire d'un bourrelet assurant sa fixation sur ladite barre de seuil.Preferably, the upper edge of the threshold bar has a narrowed slot for receiving the free edge of the sheet which is integral with a bead ensuring its attachment to said threshold bar.

Suivant encore une autre caractéristique le bord inférieur de la barre de seuil est solidaire d'un bourrelet souple pourvu de canaux reliés à un élément sensible inséré sur un circuit de commande de l'ouverture de la porte, de manière que toute déformation du bourrelet souple commande l'ouverture de ladite porte. Ainsi, on réalise une sécurité évitant tous risques de fermeture de la porte si un objet se trouve dans l'embrasure de celle-ci.According to yet another characteristic, the lower edge of the threshold bar is secured to a flexible bead provided with channels connected to a sensitive element inserted on a circuit for controlling the opening of the door, so that any deformation of the flexible bead controls the opening of said door. Thus, there is a security avoiding any risk of closing the door if an object is in the doorway thereof.

Suivant une caractéristique de détail, les interrupteurs de fin de course comprennent un bras mobile faisant saillie dans les guides verticaux et disposé à des emplacements présélectionnés sur le parcours des galets de guidage de la barre de seuil dans lesdits guides verticaux.According to a characteristic of detail, the limit switches include a movable arm projecting in the vertical guides and arranged at preselected locations on the path of the guide rollers of the threshold bar in said vertical guides.

Enfin, la porte souple peut comporter, le long des guides verticaux, de part et d'autre de ceux-ci, des plaques verticales pourvues de poils coopérant avec les bords verticaux de la feuille souple. On assure ainsi l'étanchéité de ladite porte.Finally, the flexible door may comprise, along the vertical guides, on either side thereof, vertical plates provided with bristles cooperating with the vertical edges of the flexible sheet. This ensures the tightness of said door.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels:

  • Figure 1 est une vue en perspective d'une porte souple, selon l'invention,
  • Figure 2 est une vue en coupe, à plus grande échelle, de l'extrémité inférieure d'un montant,
  • Figure 3 est une vue en coupe suivant la ligne III-III de la figure 2,
  • Figure 4 est une vue en perspective montrant une pièce d'extrémité.
The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the accompanying drawings, in which:
  • FIG. 1 is a perspective view of a flexible door according to the invention,
  • FIG. 2 is a sectional view, on a larger scale, of the lower end of an upright,
  • FIG. 3 is a sectional view along line III-III of FIG. 2,
  • Figure 4 is a perspective view showing an end piece.

La porte souple, représentée aux figures comprend un bâti, désigné dans son ensemble par la référence 1 et comprenant deux montants verticaux 2 supportant un châssis 4 et contre lesquels sont fixés des guides verticaux 5.The flexible door, shown in the figures comprises a frame, generally designated by the reference 1 and comprising two vertical uprights 2 supporting a frame 4 and against which vertical guides 5 are fixed.

Les montants 2 sont reliés par une traverse 6 et le châssis 4 supporte un moteur électrique 7 dont l'arbre de sortie entraîne, à travers un variateur de vitesse 8, un pignon 9 sur lequel passe une chaîne sans fin 10 coopérant avec un pignon 11 calé sur un arbre 12 guidé dans des paliers 14 du châssis 4 et sur lequel est calé un tambour 13.The uprights 2 are connected by a cross-member 6 and the chassis 4 supports an electric motor 7 whose output shaft drives, through a variable speed drive 8, a pinion 9 over which passes an endless chain 10 cooperating with a pinion 11 wedged on a shaft 12 guided in bearings 14 of the chassis 4 and on which a drum 13 is wedged.

Sur le tambour 13 est enroulée une feuille transparente 19 de chlorure de polyvinyle dans le bord inférieur est solidaire d'une barre de seuil 15.On the drum 13 is wound a transparent sheet 19 of polyvinyl chloride in the lower edge is secured to a threshold bar 15.

La barre de seuil 15 comprend un profilé (voir figure 3) ayant une section sensiblement en forme de H avec une âme 16 et deux barrettes 17. Les barrettes 17, au voisinage du bord supérieur, sont pliées pour former une fente rétrécie 18 traversée par le bord inférieur de la feuille 19, celui-ci étant solidaire d'un bourrelet 20 dont la section est supérieure à la largeur de la fente 18.The threshold bar 15 comprises a profile (see FIG. 3) having a substantially H-shaped section with a core 16 and two bars 17. The bars 17, in the vicinity of the upper edge, are folded to form a narrowed slot 18 traversed by the lower edge of the sheet 19, the latter being integral with a bead 20 whose section is greater than the width of the slot 18.

L'âme 16 est percée d'une série de trous 21 régulièrement espacés dont deux, situés aux extrémités, sont destinés à être traversés par des vis 22 pour la fixation de deux barrettes 23 tandis que les autres permettent le passage de vis 24 assurant la fixation d'un profilé en C 25 de maintien d'un bourrelet souple 26.The core 16 is pierced with a series of regularly spaced holes 21, two of which, located at the ends, are intended to be crossed by screws 22 for fixing two bars 23 while the others allow the passage of screws 24 ensuring the fixing of a C 25 profile for holding a flexible bead 26.

Les barrettes 23 sont solidaires d'une platine 29 supportant un axe 30 sur lequel est monté fou un galet 31, ladite platine comportant une joue 32 supportant un axe 33 sur lequel est monté fou un galet 35, les axes 30 et 33 s'étendant dans deux directions perpendiculaires l'une par rapport à l'autre. L'une des extrémités de la platine 29 est terminée par une languette 34.The bars 23 are integral with a plate 29 supporting a pin 30 on which is mounted a roller 31, said plate comprising a cheek 32 supporting a pin 33 on which is mounted a roller 35, the axes 30 and 33 extending in two directions perpendicular to each other. One of the ends of the plate 29 is terminated by a tongue 34.

Il est prévu deux platines 29 situées à chacune des extrémités de la barre de seuil 15 et qui ferment celle-ci, ces platines 29 étant fixées par les vis 22 se vissant dans les trous correspondants des barrettes 23.Two plates 29 are provided located at each end of the threshold bar 15 and which close the latter, these plates 29 being fixed by the screws 22 which are screwed into the corresponding holes of the bars 23.

Les guides 5 sont constitués par des profilés à section en U dont les extrémités libres des ailes se font vis à vis, les galets 31 guidant la barre 15 contre les faces internes des ailes, tandis que les galets 35 guident ladite barre 15 contre l'âme desdits profilés.The guides 5 are formed by profiles with a U-shaped section, the free ends of the wings face to face, the rollers 31 guiding the bar 15 against the inner faces of the wings, while the rollers 35 guide said bar 15 against the web of said sections.

Le bourrelet souple 26 comporte trois canaux longitudinaux 26a, 26b et 26c qui sont reliés par tube 37 à un élément sensible 38 inséré sur un circuit électrique qui commande automatiquement l'enroulement de la feuille 19 sur le tambour 13 si le bourrelet 26 s'écrase soit latéralement, soit à son extrémité inférieure. Un tel montage constitue un système de sécurité qui permet d'éviter la fermeture de la porte souple lorsqu'un objet est situé dans l'embrasure de celle-ci.The flexible bead 26 has three longitudinal channels 26a, 26b and 26c which are connected by tube 37 to a sensitive element 38 inserted on an electrical circuit which automatically controls the winding of the sheet 19 on the drum 13 if the bead 26 is crushed either laterally or at its lower end. Such an assembly constitutes a security system which makes it possible to avoid closing the flexible door when an object is located in the doorway thereof.

Sur l'un des guides 5 sont fixés deux interrupteurs de fin de course 39 comportant chacun un bras 40 traversant une ouverture 41 de l'âme dudit guide et dont l'extrémité libre porte un galet 42 situé sur le trajet du galet 35.On one of the guides 5 are fixed two limit switches 39 each comprising an arm 40 passing through an opening 41 of the core of said guide and the free end of which carries a roller 42 located on the path of the roller 35.

Etant donné que la feuille 19 est sujette à des variations de dimensions dues aux différences de température, on est assuré, grâce à la position des interrupteurs de fin de course 39 que la porte sera, dans la position de fermeture, disposée afin que le bourrelet 26 souple touche le sol, et dans la position d'ouverture toujours dégagée à la même hauteur. En effet, les interrupteurs 39 étant commandés par les galets 15 et disposés à des hauteurs calculées pour que l'ouverture et la fermeture de la porte s'arrêtent dans des positions déterminées, les variations éventuelles de dimension de la feuille 19 ne modifireront pas ces positions.Since the sheet 19 is subject to variations in dimensions due to temperature differences, it is ensured, thanks to the position of the limit switches 39 that the door will, in the closed position, be arranged so that the bead 26 flexible touches the ground, and in the open position always released at the same height. Indeed, the switches 39 being controlled by the rollers 15 and arranged at heights calculated so that the opening and closing of the door stop in determined positions, the possible variations in size of the sheet 19 will not modify these positions.

Il peut être prévu, de part et d'autre des montants 2 et des guides 5, des plaques verticales 45 pourvues de poils 46 coopérant avec les deux faces des bords verticaux de la feuille 19 pour assurer l'étanchéité de la porte.There may be provided, on either side of the uprights 2 and the guides 5, vertical plates 45 provided with bristles 46 cooperating with the two faces of the vertical edges of the sheet 19 to seal the door.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the embodiment which has just been described and shown. Many modifications of detail can be made without departing from the scope of the invention.
