Description

La présente invention est relative à une porte à rideau à ouverture verticale rapide.The present invention relates to a curtain door with rapid vertical opening.

On connaît déjà de nombreuses formes de réalisation de ce type de porte à rideau. Toutes ces portes à rideau à ouverture rapide comportent des glissières latérales, des barres de raidissement et un dispositif d'entraînement pour l'enroulement de sangles ainsi que des étriers ou anneaux de guidage agencés pour le passage des sangles de la porte et, éventuellement, des galets ou organes analogues roulant dans les glissières latérales. L'un des inconvénients majeurs de ces portes à rideau consiste en les-nombreux points de frottement existant entre certains éléments de la porte lors de l'enroulement ou du déroulement du rideau souple, notamment le frottement des différentes barres de raidissement l'une sur l'autre, le frottement du rideau sur les côtés latéraux des glissières et le frottement des sangles dans les anneaux de guidage et contre le rideau, ce qui entraîne soit une usure du rideau soit une usure du rideau et des sangles. De plus, l'enroulement de ce type de porte se fait avec grand bruit, les différentes barres horizontales s'entassant les unes sur les autres et les étriers et galets venant frapper sur les montants latéraux. Les poulies utilisées, à cet effet, pour l'enroulement des sangles sont placées sur l'arbre moteur, et endommagent par conséquent celles-ci lors de leur enroulement, les sangles pouvant dévier de leur trajectoire correcte et se mettre sur les arêtes vives des poulies, ce qui provoque une usure prématurée de celles-ci.Numerous embodiments of this type of curtain door are already known. All these quick-opening curtain doors have side rails, stiffening bars and a drive device for winding up straps as well as stirrups or guide rings arranged for the passage of the door straps and, optionally, rollers or the like rolling in the side rails. One of the major drawbacks of these curtain doors consists of the numerous points of friction existing between certain elements of the door during the winding or unwinding of the flexible curtain, in particular the friction of the various stiffening bars, one on the other, the friction of the curtain on the lateral sides of the slides and the friction of the straps in the guide rings and against the curtain, which causes either wear of the curtain or wear of the curtain and the straps. In addition, the winding of this type of door is done with great noise, the different horizontal bars piling up on each other and the stirrups and rollers coming to strike on the side uprights. The pulleys used for this purpose for winding the straps are placed on the motor shaft, and consequently damage the latter during their winding, the straps being able to deviate from their correct trajectory and get on the sharp edges of the pulleys, causing them to wear out prematurely.

L'invention a pour but de remédier à ces inconvénients et de procurer une porte à rideau à ouverture verticale rapide, ne comportant pratiquement plus aucun point de frottement, n'entraînant par conséquent pas d'usure prématurée soit du rideau soit des sangles, peu bruyante et qui présente, en outre, l'avantage d'être extrêmement étanche.The object of the invention is to remedy these drawbacks nients and to provide a curtain door with rapid vertical opening, having practically no more friction points, consequently not causing premature wear either of the curtain or of the straps, which is not very noisy and which, moreover, has the advantage of being extremely waterproof.

A cet effet, selon l'invention, la porte comprend une structure formée de deux montants latéraux verticaux servant de glissières et d'un caisson supérieur, un rideau souple dont une extrémité est fixée à un support sensiblement horizontal, ledit rideau s'étendant librement vers le bas en position de fermeture et étant rigidifié par des traverses horizontales réparties sensiblement régulièrement suivant la hauteur desdits montants latéraux, au moins une de ces traverses étant prévue à l'extrémité inférieure dudit rideau, ladite traverse inférieure étant agencée pour prendre appui sur des sangles par l'intermédiaire de moyens de guidage et d'enroulement de sangle disposés dans le caisson supérieur précité, lesdits moyens de guidage et d'enroulement comprenant un arbre - monté sur un support transversal supérieur, un dispositif d'entraînement de l'arbre et, pour chaque sangle, une poulie à gorge agencée pour envoyer la sangle sur l'arbre en une position correcte, lesdites sangles étant libres sur la totalité de la hauteur de la porte.To this end, according to the invention, the door comprises a structure formed by two vertical lateral uprights serving as slides and an upper box, a flexible curtain, one end of which is fixed to a substantially horizontal support, said curtain extending freely. downwards in the closed position and being stiffened by horizontal crosspieces distributed substantially regularly along the height of said lateral uprights, at least one of these crosspieces being provided at the lower end of said curtain, said lower crosspiece being arranged to bear on straps by means of guide and strap winding means arranged in the aforementioned upper box, said guide and winding means comprising a shaft - mounted on an upper transverse support, a drive device for the shaft and, for each strap, a grooved pulley arranged to send the strap onto the shaft in a correct position, said straps being linked bres over the entire height of the door.

Suivant une forme de réalisation de l'invention, le rideau s'étend sensiblement sur toute la largeur de la porte de manière à assurer l'étanchéité latérale de celle-ci.According to one embodiment of the invention, the curtain extends substantially over the entire width of the door so as to ensure the lateral sealing of the latter.

Dans les différentes figures, les mêmes notations de référence désignent des éléments identiques ou analogues.In the different figures, the same reference notations designate identical or analogous elements.

La porte à rideau à ouverture verticale représentée aux dessins annexés, comprend une structure formée de deux montants latéraux verticaux 1 servant de glissières et d'un caisson supérieur 2. Le rideau souple 3 de la porte est fixé à un support horizontal 4, ce rideau 3 s'étendant librement vers le bas en position de fermeture, comme on peut le voir plus particulièrement sur les figures 1 et 2, et étant rigidifié par des traverses horizontales 5 réparties régulièrement sur la hauteur des montants latéraux 1. La traverse horizontale 5, prévue à l'extrémité inférieure 6 du rideau 3, prend appui sur des sangles 7 par l'intermédiaire d'une poulie de renvoi à gorge 8 ainsi que d'un arbre 9 monté sur un support transversal 10, l'arbre 9 étant entraîné par un dispositif d'entraînement 11, de telle sorte que la rotation de l'arbre 9 dans un sens ou dans l'autre assure l'enroulement ou le déroulement des sangles 7. Chaque poulie de renvoi 8, fixée au caisson 2, est pourvue d'une gorge 12 agencée pour envoyer correctement la sangle correspondante sur l'arbre moteur 9. Comme on peut le voir plus particulièrement sur les figures 1 et 2, chaque sangle 7 est entièrement libre sur toute la hauteur de la porte et s'enroule, par conséquent, sans dommage sur l'arbre moteur 9.The curtain door with vertical opening shown in the accompanying drawings comprises a structure formed by two vertical lateral uprights 1 serving as slides and an upper box 2. The flexible curtain 3 of the door is fixed to a horizontal support 4, this curtain 3 extending freely downwards in the closed position, as can be seen more particularly in FIGS. 1 and 2, and being stiffened by horizontal crosspieces 5 distributed regularly over the height of the lateral uprights 1. The horizontal crosspiece 5, provided at the lower end 6 of the curtain 3, bears on straps 7 by means of a grooved return pulley 8 as well as a shaft 9 mounted on a transverse support 10, the shaft 9 being driven by a drive device 11, so that the rotation of the shaft 9 in one direction or the other ensures the winding or unwinding of the straps 7. Each return pulley 8, fixed to the box 2, is provided with a groove 12 arranged e to correctly send the corresponding strap to the motor shaft 9. As can be seen more particularly in FIGS. 1 and 2, each strap 7 is completely free over the entire height of the door and is therefore wound up without damage to the motor shaft 9.

Comme on peut le voir sur la figure 3 des dessins annexés, l'enroulement du rideau se fait aisément, pratiquement sans frottement et dans un espace restreint, les traverses horizontales 5 s'enroulant pour former un cylindre.As can be seen in Figure 3 of the accompanying drawings, the curtain is wound easily, practically without friction and in a small space, the horizontal crosspieces 5 winding to form a cylinder.

On notera également, ainsi qu'on l'a déjà mentionné précédemment, que l'étanchéité latérale de la porte est excellente. En effet, le rideau souple 3 s'étend sur toute la largeur de la porte. et vient s'appliquer sur les montants latéraux 1, assurant ainsi une excellente étanchéité latérale à l'air.It will also be noted, as already mentioned previously, that the lateral sealing of the door is excellent. Indeed, the flexible curtain 3 extends over the entire width of the door. and is applied to the side uprights 1, thus ensuring a excellent lateral air tightness.

On comprendra aisément, compte tenu de ce qui précède, qu'en partant de la position de fermeture représentée par les figures 1 et 2, la commande du dispositif d'entraînement 11 dans le sens correct va provoquer l'enroulement des sangles sur les poulies 8 et, par conséquent, l'enroulement du rideau 3 en un cylindre.It will be readily understood, taking into account the above, that starting from the closed position represented by FIGS. 1 and 2, the control of the drive device 11 in the correct direction will cause the straps to be wound on the pulleys 8 and, consequently, the winding of the curtain 3 into a cylinder.

Il doit être entendu que la présente invention n'est en aucune façon limitée aux formes de réalisation ci-dessus et que bien des modifications peuvent y être apportées sans sortir du cadre du présent brevet.It should be understood that the present invention is in no way limited to the above embodiments and that many modifications can be made thereto without departing from the scope of this patent.
