Description

La présente invention est relative à un dispositif de guidage d'un rideau souple comportant des traverses horizontales constituant le tablier d'une porte à rideau souple motorisée de manière à déplacer rapidement le tablier entre une position de fermeture et une position d'ouverture.The present invention relates to a device for guiding a flexible curtain comprising horizontal crosspieces constituting the curtain of a curtain door flexible motorized so as to quickly move the apron between a position of closing and an open position.

Le dispositif de guidage suivant la présente invention est plus particulièrement destiné aux portes dont le rideau souple soit s'enroule autour d'un tambour, soit s'empile par plis successifs dans un espace déterminé.The guiding device according to the present invention is more particularly intended for doors whose flexible curtain is either wrapped around a drum or stacked by successive folds in a determined space.

On connaít des portes à rideau souple qui comprennent deux supports métalliques verticaux et parallèles en forme de U ou de C pouvant être fixés soit directement dans un cadre en béton sur lequel est agencée la porte, soit par l'intermédiaire d'éléments élastiques disposés entre les montants verticaux du cadre en béton et les supports métalliques comme décrit dans la demande de brevet européen EP-0587586 A.We know flexible curtain doors that include two metal supports vertical and parallel in U or C shape which can be fixed either directly in a concrete frame on which the door is arranged, either through elastic elements arranged between the vertical uprights of the concrete frame and the metal supports as described in the European patent application EP-0587586 A.

Chaque support métallique reçoit un chemin de guidage rectilignes permettant de guider les bords latéraux du rideau souple lors de ses déplacements entre une position de fermeture et une position d'ouverture.Each metal support receives a rectilinear guide path allowing guide the side edges of the flexible curtain when moving between a closed position and an open position.

Les chemins de guidage sont réalisés dans un profilé en U dans lequel est prévu une glissière permettant de guider les bords latéraux du rideau dans toutes les directions. En effet chaque chemin de guidage comporte une glissière présentant un profil interne sensiblement carré dont l'un des bords présente une fente ménagée sur toute la hauteur dudit chemin de guidage pour le passage du rideau.The guide tracks are made in a U-profile in which is provided a slide to guide the side edges of the curtain in all directions. Indeed, each guide path has a slide having a substantially square internal profile, one edge of which has a slot over the entire height of said guide path for the passage of the curtain.

Les chemins de guidage sont réalisés en une matière semi-élastique, de manière à permettre, lorsqu'une force de traction est exercée sur le rideau de dégager les bords latéraux du rideau des chemins de guidage.The guide tracks are made of a semi-elastic material, so that allow, when a tensile force is exerted on the curtain to release the lateral edges of the curtain of the guideways.

Ce genre de porte à rideau souple comporte certains inconvénients en ce qui conceme l'impossibilité d'intervenir et de nettoyer les parois intemes des glissières prévus dans chaque chemin de guidage. En effet lorsque ces portes sont disposées dans des locaux pour le traitement de produits alimentaires, il est impératif de nettoyer entièrement la porte et plus particulièrement les chemins de guidage après chaque joumée de travail. La structure des chemins de guidage décrite précédemment ne permet pas cette intervention sans un démontage complet de la porte. This kind of flexible curtain door has certain disadvantages in relates to the impossibility of intervening and cleaning the inner walls of the slides provided in each guide path. Indeed when these doors are arranged in premises for processing food, it is imperative to thoroughly clean the door and more particularly the guideways after each day of work. The structure of the guideways described previously does not allow this intervention without a complete disassembly of the door.

De plus, les chemins de guidage présentent une très faible résistance au choc, car le profil en matière semi-élastique est affaibli par la fente prévue sur toute sa hauteur.In addition, the guideways have a very low impact resistance, because the profile in semi-elastic material is weakened by the slot provided over its entire height.

Plus traditionnellement les glissières sont constituées d'un profil ouvert en U dont la largeur du fond est identique de haut en bas, solution mal adaptée au mode de fonctionnement de ces portes.More traditionally, the slides consist of an open U-shaped profile, the width of the bottom is identical from top to bottom, solution ill-suited to the mode of operation of these doors.

Ainsi, pour les portes à empilage d'un rideau souple ces glissières ont nécessité de loger, en situation de porte ouverte, un volume important de laies empilées, alors que le passage nécessaire et suffisant, en positon de fermeture, se limite à l'épaisseur du rideau.Thus, for the stacking doors of a flexible curtain, these slides required house, in an open door situation, a large volume of stacked lays, then that the necessary and sufficient passage, in the closed position, is limited to the thickness of the curtain.

De même, pour les portes à enroulement le rideau se déplace dans son plan vertical du fait de la modification de diamètre d'enroulement du rideau suivant la position ouverte ou fermée. Une largeur plus importante de la glissière dans sa partie haute est donc recommandée permettant la descente du rideau sans contrainte et sans frottement.Likewise, for roller doors the curtain moves in its vertical plane due to the modification of the curtain's winding diameter depending on the position open or closed. A greater width of the slide in its upper part is therefore recommended allowing the curtain to be lowered without constraint and without friction.

Le dispositif de guidage suivant la présente invention a pour but de remédier à ces inconvénients.The aim of the guide device according to the present invention is to remedy these disadvantages.

Le dispositif de guidage suivant l'invention comprend sur les montants verticaux et opposés d'une porte à rideau souple des sangles qui sont disposées l'une en face de l'autre pour constituer sur chaque montant une glissière de guidage des traverses horizontales, lesdites sangles étant tendus et fixées chacune entre deux points extrêmes solidaires du montant correspondant pour permettre à chaque sangle, sous la pression d'une force extérieure, de se déformer élastiquement et de revenir à sa position d'origine sans détérioration.The guide device according to the invention comprises on the vertical uprights and opposite of a flexible curtain door straps which are arranged one opposite on the other to form a cross slide guide on each upright horizontal, said straps being tensioned and each fixed between two points extremes integral with the corresponding amount to allow each strap, under the pressure of an external force, to elastically deform and return to its original position without deterioration.

Le dispositif de guidage conforme à l'invention comporte sur chaque montant de la porte deux sangles présentant une partie inclinée pour conformer un espace de réception du rideau souple et une partie droite et verticale de manière que les sangles soient parallèles l'une par rapport à l'autre pour permettre le guidage dudit rideau lors de ses déplacements verticaux entre une position de fermeture et une position d'ouverture.The guide device according to the invention comprises on each amount of the carries two straps having an inclined part to conform a space of reception of the flexible curtain and a straight and vertical part so that the straps are parallel to each other to allow guidance of said curtain during its vertical movements between a closed position and a open position.

Le dispositif de guidage suivant la présente invention consiste en ce que chaque sangle présente entre un doigt de retenue et une butée, une partie inclinée pour constituer, avec l'autre sangle, un espace en forme de V prévu pour recevoir le déroulement du rideau souple, d'une porte à enroulement, lorsque ce dernier est retenu lors de sa descente par un obstacle.The guiding device according to the present invention consists in that each strap present between a retaining finger and a stop, an inclined part for constitute, with the other strap, a V-shaped space intended to receive the unwinding of the flexible curtain, of a rolling door, when the latter is restrained during its descent by an obstacle.

Le dispositif de guidage suivant l'invention consiste en ce que chaque sangle présente entre un doigt de retenue et une butée une première partie inclinée et entre la butée et une autre butée médiane une seconde partie inclinée pour constituer, avec l'autre sangle, un espace à ouverture progressive afin de recevoir les plis du rideau souple d'une porte à empilage lors de sa fermeture. The guiding device according to the invention consists in that each strap has a first inclined part between a retaining finger and a stop the stop and another central stop a second inclined part to constitute, with the other strap, a space with progressive opening in order to receive the folds of the flexible curtain of a stacking door when closed.

Le dispositif de guidage suivant la présente invention comporte des sangles dont la largeur de chacune est dépendante de celle du rideau souple de la porte.The guiding device according to the present invention comprises straps, the width of each is dependent on that of the flexible curtain of the door.

Le dispositif de guidage conforme à l'invention comporte des butées sur lesquelles viennent prendre appuis les sangles pour permettre de conformer le profil de chaque sangle sur toute sa hauteur.The guide device according to the invention comprises stops on which take support from the straps to allow the profile of each strap over its entire height.

Le dispositif de guidage suivant la présente invention présente entre deux sangles d'un montant de la porte et plus particulièrement dans la partie droite et verticale de ces dernières une distance d voisine de celle de l'épaisseur du rideau souple.The guide device according to the present invention has between two straps of a door jamb and more particularly in the right and vertical part of the latter a distance d close to that of the thickness of the flexible curtain.

Le dispositif de guidage suivant la présente invention comporte des sangles qui sont susceptibles chacune, sous la pression d'une force extérieure, de se déformer élastiquement d'une part autour de son axe vertical et d'autre part perpendiculairement à son axe vertical, et de revenir dans sa position d'origine sans détérioration.The guiding device according to the present invention comprises straps which are each susceptible, under the pressure of an external force, to deform elastically on the one hand around its vertical axis and on the other hand perpendicular to its vertical axis, and return to its original position without deterioration.

La présente invention concerne également une porte à rideau souple qui comprend des montants verticaux et opposés sur lesquels sont fixés des sangles disposées l'une en face de l'autre pour constituer sur chaque montant une glissière de guidage des traverses horizontales du rideau souple, lesdites sangles étant tendus et fixées chacune entre deux points extrêmes solidaires des montants pour permettre à chaque sangle, sous la pression d'une force extérieure, de se déformer élastiquement et de revenir à sa position d'origine sans détérioration.The present invention also relates to a flexible curtain door which comprises vertical and opposite uprights on which are fixed straps arranged one opposite the other to form a guide rail on each upright horizontal crosspieces of the flexible curtain, said straps being stretched and fixed each between two extreme points integral with the uprights to allow each strap, under the pressure of an external force, to deform elastically and return to its original position without deterioration.

La description qui va suivre en regard des dessins annexés, donnés à titre d'exemples non limitatifs, permettra de mieux comprendre l'invention, les caractéristique qu'elle présente et les avantages qu'elle est susceptible de procurer:The following description with reference to the accompanying drawings, given as of nonlimiting examples, will allow a better understanding of the invention, the characteristic which it presents and the advantages which it is likely to provide:

Figure 6 est une vue en perspective montrant un montant de la porte de figure 5 muni du dispositif de guidage suivant l'invention en position fermé. Figure 6 is a perspective view showing an upright of the door of Figure 5 provided with the guide device according to the invention in the closed position.

Figure 7 est une vue de face représentant la porte de figure 5 en position ouverte.Figure 7 is a front view showing the door of Figure 5 in the open position.

Figure 8 est une vue en perspective montrant un montant de la porte de figure 7 muni du dispositif de guidage suivant l'invention en position ouverte.Figure 8 is a perspective view showing an upright of the door of Figure 7 provided with the guide device according to the invention in the open position.

On a représenté en figures 1 et 2 une porte 1 comportant deux montants latéraux 2 et 3 qui sont généralement fixés contre les parois verticales d'une ouverture à obstruer. Les montants opposées et verticaux 2 et 3 sont reliés entre eux dans la partie supérieure de la porte 1 par un tambour d'enroulement 4 d'un rideau souple 5.FIGS. 1 and 2 show a door 1 comprising two lateral uprights 2 and 3 which are generally fixed against the vertical walls from an opening to obstruct. The opposite and vertical uprights 2 and 3 are interconnected in the upper part of door 1 by a winding drum 4 of a flexible curtain 5.

Les montants 2 et 3 sont solidaires d'un dispositif de guidage 6 du rideau souple 5 lors de ses déplacements entre une position de fermeture et une position d'ouverture.The uprights 2 and 3 are integral with a guide device 6 of the flexible curtain 5 when moving between a closed position and a position opening hours.

On note que le rideau souple comporte des fourreaux 5a dans lesquels sont introduits des traverses horizontales de renfort 5b dont les extrémités coopèrent avec les dispositifs de guidage 6 prévus sur chaque montants 2 et 3 (figure 2).Note that the flexible curtain has sleeves 5a in which are introduced horizontal reinforcing crosspieces 5b whose ends cooperate with the guiding devices 6 provided on each uprights 2 and 3 (Figure 2).

Chaque dispositif de guidage 6 comporte deux sangles 6a et 6b disposées l'une en face de l'autre pour constituer sur chaque montant 2 et 3 une glissière 6c de guidage du rideau 5 et de ses traverses 5b.Each guide device 6 comprises two straps 6a and 6b arranged one in face of the other to constitute on each upright 2 and 3 a guide slide 6c curtain 5 and its crossbeams 5b.

Par souci de clarté et de compréhension, on décrira uniquement le dispositif de guidage 6 prévu sur le montant 2 étant donné que l'autre agencé sur le montant 3 est identique.For the sake of clarity and understanding, we will only describe the guide 6 provided on the upright 2 since the other arranged on the upright 3 is identical.

Les sangles 6a et 6b du dispositif de guidage 6 présentent respectivement à l'une de leur extrémité une boucle 6d, 6e qui coopère chacune avec un point extrème formé par un doigt de retenu 6f, 6g solidaire du montant 2. Les doigts de retenu 6f et 6g sont disposés l'un en face de l'autre et à proximité du tambour 4 recevant le rideau 5 de la porte 1.The straps 6a and 6b of the guide device 6 respectively have at one of their end a loop 6d, 6e which each cooperates with an end point formed by a retaining finger 6f, 6g secured to the upright 2. The retaining fingers 6f and 6g are arranged one opposite the other and close to the drum 4 receiving the curtain 5 from door 1.

Dans la partie inférieure du montant 2 est prévu deux tendeurs 6h et 6i formant les autres points extrèmes du dispositif de guidage qui reçoivent respectivement l'extrémité opposée à celle des boucles 6f et 6g des sangles 6a et 6b. Les tendeurs 6h et 6i sont placés sur un même niveau et présentent par exemple un profil extérieur six pans pour permettre à l'aide d'une clef de tendre chaque sangle 6a et 6b entre deux points extrêmes constitués par les doigts 6f, 6g et les tendeurs 6h, 6i.In the lower part of the upright 2 is provided two tensioners 6h and 6i forming the other extreme points of the guide device which respectively receive the end opposite to that of the loops 6f and 6g of the straps 6a and 6b. The tensioners 6h and 6i are placed on the same level and for example have a profile outside hexagon to allow using a key to tighten each strap 6a and 6b between two extreme points constituted by the fingers 6f, 6g and the tensioners 6h, 6i.

Entre les deux points extrêmes du dispositif de guidage 6 est prévu deux butées opposées 6j et 6k sur lesquelles viennent prendre appuis respectivement les sangles 6a et 6b.Between the two extreme points of the guide device 6 is provided two stops opposite 6j and 6k on which come to bear respectively the straps 6a and 6b.

Les butées 6j et 6k sont disposées d'une part décalées par rapport aux doigt 6f et 6g et d'autre part sur le même axe vertical que celui des tendeurs 6h et 6i. Cette configuration permet aux sangles 6a et 6b de présenter une partie inclinée pour conformer un espace de réception E du rideau souple 5 à proximité du tambour 4 dont on verra mieux plus loin la fonction. The stops 6j and 6k are arranged on the one hand offset with respect to the fingers 6f and 6g and on the other hand on the same vertical axis as that of the 6h and 6i tensioners. This configuration allows the straps 6a and 6b to have an inclined part for conform a receiving space E of the flexible curtain 5 near the drum 4 whose function will be better seen later.

Les sangles 6a et 6b présentent dans le prolongement de l'espace de réception E une partie droite et vertical de manière que lesdites sangles soient parallèles l'une par rapport à l'autre pour permettre le guidage du rideau souple 5 lors de ses déplacements verticaux entre une position de fermeture et une position d'ouverture.The straps 6a and 6b have in the extension of the reception space E a straight and vertical part so that said straps are parallel one relative to each other to allow the flexible curtain 5 to be guided during its vertical movements between a closed position and an open position.

Ainsi chaque sangle 6a et 6b présente respectivement une partie inclinée entre les doigts 6f, 6g et les butées 6d, 6k pour constituer l'espace E qui affecte plus particulièrement une forme de V.Thus each strap 6a and 6b respectively has an inclined part between the fingers 6f, 6g and the stops 6d, 6k to constitute the space E which affects more particularly a form of V.

En figures 3 et 4 on a montré le rideau souple 5 de la porte à enroulement 1 qui rencontre lors de sa descente un obstacle 7. Dans ses conditions le rideau 5 continue à se dérouler et vient se réceptionner dans l'espace E du dispositif de guidage 6. Il suffit ensuite d'inverser la rotation du tambour 4 pour enrouler à nouveau le rideau 5.In Figures 3 and 4 there is shown the flexible curtain 5 of the roll-up door 1 which encountered an obstacle during its descent 7. Under its conditions the curtain 5 continues to unfold and is received in space E of the guide 6. It then suffices to reverse the rotation of the drum 4 to wind up again the curtain 5.

On a représenté en figures 5 et 8 une porte à empilage 1' comportant deux montants latéraux 2' et 3' qui sont fixés contre les parois verticales d'une ouverture à obstruer.FIGS. 5 and 8 show a stacking door 1 ′ comprising two uprights side 2 'and 3' which are fixed against the vertical walls of an opening to be blocked.

Les montants opposées et verticaux 2' et 3' sont reliés entre eux dans la partie supérieure de la porte 1' par un tambour d'enroulement 4' et une barre transversale fixe 4'a sur laquelle est maintenu un rideau souple 5'.The opposite and vertical uprights 2 'and 3' are interconnected in the part top of door 1 'by a winding drum 4' and a crossbar fixed 4'a on which a flexible curtain 5 'is maintained.

Les montants 2' et 3' sont solidaires d'un dispositif de guidage 6 semblable à celui décrit précédemment pour la porte à enroulement 1. Le dispositif de guidage 6 comporte une glissière 6c qui permet de guider le rideau souple 5' lors de ses déplacements entre une position de fermeture et une position d'ouverture.The uprights 2 'and 3' are integral with a guiding device 6 similar to that previously described for the roll-up door 1. The guide device 6 has a slide 6c which guides the flexible curtain 5 'during its movements between a closed position and an open position.

Le rideau souple 5' comporte des fourreaux 5'a pourvus d'ouvertures 5'c pour le passage de traverses horizontales de renfort 5'b. Le rideau souple 5' présente dans sa partie inférieure une autre traverse horizontale 5'd qui est reliée par des sangles de traction 5'e au tambour d'enroulement 4'. Les sangles 5'e sont guidées au niveau de chaque traverse horizontales de renfort 5'b par l'intermédiaire de passes sangles 5'f disposés dans les ouvertures 5'c des fourreaux 5'a. Il est également prévu des fourreaux 5'a sans ouverture et dans lesquels sont introduits d'autres traverses de renfort 5'b.The flexible curtain 5 ′ has sleeves 5 ′ a provided with openings 5 ′ c for the passage of horizontal reinforcing beams 5'b. The 5 'flexible curtain in its lower part, another horizontal cross 5 'which is connected by straps traction 5'e to the winding drum 4 '. The 5'e straps are guided at level of each horizontal reinforcement crosspiece 5'b by means of strap passes 5'f arranged in the openings 5'c of the sleeves 5'a. There are also plans 5'a sleeves without opening and into which are inserted other sleepers reinforcement 5'b.

Le système d'entraínement du rideau 5' décrit ci-dessus permet à ce dernier lors de son ouverture de venir s'empiler dans la partie supérieure de la porte 1'.The 5 'curtain drive system described above allows the curtain to its opening to be stacked in the upper part of the door 1 '.

Par souci de clarté et de compréhension, on décrira uniquement le dispositif de guidage 6 prévu sur le montant 2' étant donné que l'autre agencé sur le montant 3' est identique. De plus, on procédera principalement à la description des éléments nouveaux et complémentaires du dispositif de guidage 6 qui ne sont pas prévus pour la porte à enroulement 1.For the sake of clarity and understanding, we will only describe the guide 6 provided on the upright 2 'since the other arranged on the upright 3' is identical. In addition, we will mainly describe the elements new and complementary to the guide device 6 which are not intended to the roll-up door 1.

Ainsi les sangles 6a et 6b muni de leurs boucles 6b et 6c sont fixées et tendues entre deux points extrèmes solidaires du montant 2', c'est à dire entre les doigts 6f, 6g et les tendeurs 6h, 6i. Thus the straps 6a and 6b provided with their loops 6b and 6c are fixed and stretched between two extreme points integral with the upright 2 ′, that is to say between the fingers 6f, 6g and the tensioners 6h, 6i.

Chaque sangle 6a et 6b vienne prendre appuie entre les doigts 6f, 6g et les tendeurs 6h, 6i sur une première butée haute 6j, 6k et sur une seconde butée médiane 6l, 6m.Each strap 6a and 6b comes to take support between the fingers 6f, 6g and the tensioners 6h, 6i on a first high stop 6j, 6k and on a second middle stop 6l, 6m.

Les sangles 6a, 6b présentent entre les doigts 6f, 6g et les butées 6j, 6k une première inclinaison qui se prolonge par une seconde inclinaison de pente différente entre les butées 6j, 6k et les butées médianes 6l, 6m.The straps 6a, 6b have between the fingers 6f, 6g and the stops 6j, 6k a first inclination which is extended by a second inclination of different slope between the stops 6j, 6k and the middle stops 6l, 6m.

cette configuration permet aux sangles 6a et 6b de délimiter un espace S à ouverture progressive afin de recevoir les plis du rideau souple 5' lors de son ouverture (figures 7 et 8).this configuration allows the straps 6a and 6b to delimit a space S to progressive opening to receive the folds of the flexible curtain 5 'during its opening (Figures 7 and 8).

Les sangles 6a et 6b présentent dans le prolongement de l'espace S une partie droite et verticale de manière que lesdites sangles soient parallèles l'une par rapport à l'autre pour permettre le guidage du rideau souple 5' lors de ses déplacements.The straps 6a and 6b present in the extension of the space S a part straight and vertical so that said straps are parallel to each other to the other to allow the flexible curtain 5 'to be guided while it is moving.

On constate que les dispositifs de guidage 6 solidaires des montants 2,2' et 3,3' des portes 1,1' sont accessibles sans démontage et facile à nettoyer lorsque ces portes sont destinées au milieu alimentaire.It can be seen that the guide devices 6 integral with the uprights 2.2 ′ and 3.3 ′ of the 1.1 'doors are accessible without dismantling and easy to clean when these doors are intended for the food industry.

De plus les dispositifs de guidage 6 prévus sur les portes 1 et 1' comportent des sangles 6a et 6b d'une largeur qui dépend de celle du rideau 5, 5' à déplacer.In addition, the guide devices 6 provided on the doors 1 and 1 'include straps 6a and 6b of a width which depends on that of the curtain 5, 5 'to be moved.

Les dispositifs de guidage 6 présentent entre deux sangles 6a, 6b d'un montant de la porte et plus particulièrement dans la partie droite et verticale de ces dernières une distance d voisine de celle de l'épaisseur du rideau souple 5, 5'.The guide devices 6 have between two straps 6a, 6b of an amount of the door and more particularly in the right and vertical part of these a distance d close to that of the thickness of the flexible curtain 5, 5 '.

On note que les dispositif de guidage 6 comportent des sangles 6a, 6b qui sont susceptibles chacune, sous la pression d'une force extérieure, de se déformer élastiquement d'une part autour de son axe vertical et d'autre part perpendiculairement à son axe vertical, et de revenir dans sa position d'origine sans détérioration.It will be noted that the guide devices 6 include straps 6a, 6b which are each susceptible, under the pressure of an external force, to deform elastically on the one hand around its vertical axis and on the other hand perpendicular to its vertical axis, and return to its original position without deterioration.

En effet, la relative déformation élastique des sangles 6a, 6b lors d'un blocage du rideau souple 5, 5' ou d'un choc latéral permet le dégondage des traverses horizontales sans rique de détérioration de ces dernières et des sangles.Indeed, the relative elastic deformation of the straps 6a, 6b during a blocking of the flexible curtain 5, 5 'or a side impact allows the unfolding of the sleepers horizontal without risk of deterioration of the latter and of the straps.

En outre, le dispositif de guidage 6 permet de réduire les bruits de fonctionnement car il n'y a plus de contact métal contre métal comme cela existait dans les autres portes.In addition, the guide device 6 makes it possible to reduce operating noise. because there is no longer metal-to-metal contact as there was in the others doors.
