Description

DISPOSITIF DE FERMETURE, DE SEPARATION OU DE COUVERTURE CLOSING, SEPARATING, OR COVERING DEVICE
La présente invention est relative à un dispositif de fermeture d'une baie, de séparation d'un local ou de couverture d'une piscine, silo, etc., comprenant un rideau pouvant s'enrouler autour d'un axe d'enroulement présentant des bords latéraux flexibles qui sont maintenus dans des chemins de guidage lors de l'enroulement et du déroulement du rideau.The present invention relates to a device for closing a bay, for separating a room or for covering a swimming pool, silo, etc., comprising a curtain which can be wound around a winding axis having flexible side edges which are held in guide tracks during the winding and unwinding of the curtain.
Surtout pour des rideaux d'une superficie relativement importante, lorsque ces derniers sont déroulés pour la fermeture d'une baie par exemple, la pression agissant sensiblement perpendiculairement sur une de ses faces peut être relativement importante, notamment pour des rideaux exposés au vent.Especially for curtains with a relatively large surface area, when the latter are unwound for closing a bay for example, the pressure acting substantially perpendicularly on one of its faces can be relatively high, in particular for curtains exposed to the wind.
Ceci a comme conséquence que, pour les dispositifs de fermeture connus de ce type, les chemins de guidage, dans lesquels se déplacent et sont maintenus les bords du rideau, peuvent subir des efforts très inégaux d'un côté du rideau par rapport au côté opposé de celui-ci. Il arrive même que tous les efforts exercés par les bords précités sur les chemins de guidage puissent se concentrer d'un seul côté du rideau et créer ainsi une torsion sur certaines parties de ces chemins de guidage avec comme résultat une usure irrégulière tant des chemins de guidage que des bords du rideau et, de plus, un risque accru que ces bords se dégagent intempestiventent des chemins de guidage pouvant détériorer ainsi ces derniers. Un autre inconvénient non négligeable pour des dispositifs de fermeture d'une certaine dimension est le montage du rideau, qui nécessite généralement une mise au point laborieuse par une main-d'oeuvre spécialisée pour assurer un glissement avec un frottement contrôle des bords du rideau dans ses chemins de guidage, un enroulement et déroulement uniformes et une pianéite parfaite du rideau en position déroulée.This has the consequence that, for known closing devices of this type, the guide tracks, in which the edges of the curtain move and are maintained, can undergo very unequal forces on one side of the curtain relative to the opposite side. of it. It even happens that all the forces exerted by the aforementioned edges on the guide tracks can be concentrated on one side of the curtain and thus create a twist on certain parts of these guide tracks with as a result irregular wear both guide only edges of the curtain and, in addition, an increased risk that these edges are released untimely guide paths can thus deteriorate them. Another non-negligible drawback for closure devices of a certain size is the mounting of the curtain, which generally requires laborious adjustment by a skilled workforce to ensure sliding with controlled friction at the edges of the curtain. its guide paths, a uniform winding and unwinding and perfect pianéite of the curtain in the unrolled position.
L'invention a essentiellement pour but de remédier aux inconvénients précités et ceci d'une manière extrêmement simpie mais très efficace.The object of the invention is essentially to remedy the aforementioned drawbacks and this in an extremely simple but very effective manner.
A cet effet, suivant l'invention, ies chemins de guidage précités sont montés sur un support de manière élastique et/ou à pivotement autour d'un axe sensiblement parallèle à leur axe longitudinal, et ce d'une manière telle que les bords latéraux susdits puissent être maintenus dans ces chemins de guidage lors d'un déplacement de ces derniers par rapport au support.To this end, according to the invention, the aforementioned guide tracks are mounted on a support in an elastic manner and / or pivotally about an axis substantially parallel to their longitudinal axis, and in such a way that the lateral edges aforementioned can be maintained in these guide paths during a movement of the latter relative to the support.
Avantageusement, les chemins de guidage sont montés par l'intermédiaire de moyens élastiques sur le support, de manière â pouvoir subir un déplacement dans la direction du rideau lorsqu'une force est exercée sur ce dernier.Advantageously, the guide tracks are mounted by means of elastic means on the support, so as to be able to undergo a displacement in the direction of the curtain when a force is exerted on the latter.
Suivant une forme de réalisation particulière de l'invention, ies chemins de guidage sont agencés sur des tiges s'étendant sensiblement verticalement par rapport â l'axe longitudinal de ces chemins de guidage et montés avec un certain jeu dans des trous prévus dans une paroi du support, ies moyens élastiques précités comprenant un ressort hélicoïdal enfilé sur la tige susdite du côte opposé de cette paroi par rapport aux chemins de guidage et s'appuyant contre cette paroi. D'autres détails et particularités de l'invention ressortiront de la description, donnée ci- après, a titre d'exemple non limitatif, de plusieurs formes, de réalisation particulières de l'invention avec référence aux dessins annexés.According to a particular embodiment of the invention, the guideways are arranged on rods extending substantially vertically with respect to the longitudinal axis of these guideways and mounted with a certain clearance in holes provided in a wall of the support, the above-mentioned elastic means comprising a helical spring threaded onto the aforementioned rod on the opposite side of this wall with respect to the guide tracks and pressing against this wall. Other details and particularities of the invention will emerge from the description, given below, by way of nonlimiting example, of several specific embodiments of the invention with reference to the appended drawings.

La figure 4 est une coupe transversale, analogue à celle de la figure 2, d'une deuxième forme de réalisation du dispositif suivant l'invention.Figure 4 is a cross section, similar to that of Figure 2, of a second embodiment of the device according to the invention.
La figure 5 est également une coupe transversale analogue à celle de la figure 2 d'une troisième forme de réalisation du dispositif suivant 1 ' invention.Figure 5 is also a cross section similar to that of Figure 2 of a third embodiment of the device 1 according to the invention.
Dans ies différentes figures, les mêmes chiffres de référence se rapportent aux mêmes éléments ou â des éléments analogues.In the various figures, the same reference numerals refer to the same elements or to analogous elements.
La forme de réalisation du dispositif de fermeture suivant l'invention, tel que représentée aux figures 1 à 3, comprend un rideau 1 pouvant s'enrouier autour d'un axe d'enroulement (non représentej et est p.e. destine à la fermeture d'une baie, telle qu'une entrée de garage, d'atelier, de hangar, et également comme cloison de séparation d'un local, ou encore au recouvrement d'une piscine, d'un silo, etc.The embodiment of the closure device according to the invention, as shown in FIGS. 1 to 3, comprises a curtain 1 which can become tangled around a winding axis (not shown and is intended for the closure of a bay, such as a garage entrance, workshop, shed, and also as a partition wall of a room, or to cover a swimming pool, a silo, etc.
Ce rideau 1 présente des bords latéraux flexibles 2, qui font saillie par rapport au plan du rideau et qui sont maintenus à glissement dans des chemins de guidage 3, prévus latéralement de .part et d'autre de la baie à obturer p.e.This curtain 1 has flexible lateral edges 2, which project relative to the plane of the curtain and which are kept sliding in guide tracks 3, provided laterally from either side of the opening to be closed eg
Ce dispositif est essentiellement caractérisé par le fait que les chemins de guidage 3 sont montés sur un support 4, délimitant latéralement la baie, d'une manière élastique et/ou à pivotement autour d'un axe sensiblement parallèle à l'axe longitudinal de ces chemins de guidage, et ceci de manière telle que ies bords latéraux 2 du rideau puissent continuer à être maintenus dans ces chemins de guidage lors d'un déplacement de ces derniers par rapport au support 4. En fait, c'est l'ensemble des parties du chemin de guidage qui maintiennent le bord du rideau qui est monté élastiquement et/ou à pivotement sur le support 4. Des moyens pourraient toutefois être prévus pour permettre le dégagement de ces bords latéraux 2 de leurs chemins de guidage lorsque la force de traction exercée par le rideau sur ces derniers dépasse une certaine valeur. Ceci est le cas lorsque les chemins de guidage présentent une certaine élasticité pour pouvoir s'ouvrir lorsqu'une certaine traction est exercée sur le rideau. Une autre possibilité est que certaines parties des chemins de guidage mêmes seraient montées à rotation par rapport â d'autres parties de ceux-ci et pourraient s'ouvrir et libérer ainsi les bords latéraux du rideau lorsque ce dernier est sollicité avec une certaine force. une telle possibilité est décrite et représentée dans la demande de brevet européen 0405093. En fait, d'une façon générale, il s'agit, suivant l'invention, de chemins de guidage qui sont montes élastiquement et/ou à rotation par leur base sur un support fixe 4, les parties de ces derniers, destinées au maintien et guidage proprement dits, n'étant donc pas concernées. Plus par iculièrement, dans cette forme de réalisation spécifique du dispositif de fermeture suivant l'invention, ies cne ins de guidage 3 sont montes par l'intermédiaire de moyens élastiques, formés de ressorts hélicoïdaux 5, sur le support 4, de manière à pouvoir subir ainsi un déplacement dans la direction du rideau 1 lorsqu'une force, illustrée par la flèche 6 sur la figure 3, est appliquée sur celui-ci.This device is essentially characterized in that the guide tracks 3 are mounted on a support 4, laterally delimiting the bay, in an elastic manner and / or pivoting around an axis substantially parallel to the longitudinal axis of these guideways, and this in such a way that the lateral edges 2 of the curtain can continue to be maintained in these guideways when the latter move relative to the support 4. In fact, this is the set of parts of the guide path which hold the edge of the curtain which is mounted resiliently and / or pivotally on the support 4. Means could however be provided to allow the release of these lateral edges 2 from their guide paths when the traction force exerted by the curtain on them exceeds a certain value. This is the case when the guide tracks have a certain elasticity in order to be able to open when a certain traction is exerted on the curtain. Another possibility is that certain parts of the guide tracks themselves would be mounted in rotation with respect to other parts thereof and could open and thus release the side edges of the curtain when the latter is stressed with a certain force. such a possibility is described and represented in European patent application 0405093. In fact, generally, it is, according to the invention, guide tracks which are mounted resiliently and / or rotatable by their base on a fixed support 4, the parts of the latter, intended for the maintenance and guidance proper, therefore not being concerned. More specifically, in this specific embodiment of the closure device according to the invention, the guide ins 3 are mounted by means of elastic means, formed by helical springs 5, on the support 4, so as to be able to thus undergo a displacement in the direction of the curtain 1 when a force, illustrated by the arrow 6 in FIG. 3, is applied thereto.
Les chemins de guidage 3 sont agences sur des tiges 7 s'étendant verticalement par rapport à l'axe longitudinal de ces derniers et montés avec un certain jeu dans des trous 8 ménagés dans la paroi du support 4, ce dernier étant, dans cette forme de réalisation, constitué d'un caisson métallique.The guide tracks 3 are arranged on rods 7 extending vertically relative to the longitudinal axis of the latter and mounted with a certain clearance in holes 8 formed in the wall of the support 4, the latter being, in this form of construction, consisting of a metal box.
Les ressorts hélicoïdaux 5 sont enfilés sur les tiges 7 à l'intérieur du caisson, en s'appuyant sur la paroi intérieure de ce dernier, du côte oppose de sa paroi sur laquelle est monté le chemin de guidage 3.The helical springs 5 are threaded on the rods 7 inside the box, pressing on the inner wall of the latter, on the opposite side of its wall on which the guide path 3 is mounted.
Les tiges précitées 7 présentent une extrémité libre filetée 9 et sont montées chacune coaxialement dans un manchon 10 passant avec un certain jeu à travers les trous 8 ménagés dans le caisson de support 4, ce manchon étant immobilise par rapport au chemin de guidage 3 par un écrou 11 vissé sur l'extrémité libre filetée 9 des tiges 7. Ainsi, ies ressorts 5, qui sont enfilés sur le manchon 10, sont maintenus avec une certaine compression entre l'écrou 11 et la face intérieure de la paroi du caisson de support sur laquelle le chemin de guidage 3 est monté. De cette façon, les ressorts exercent une certaine traction sur le chemin de guidage 3 suivant une direction perpendiculaire à l'axe longitudinal de ce dernier.The aforementioned rods 7 have a threaded free end 9 and are each mounted coaxially in a sleeve 10 passing with a certain clearance through the holes 8 formed in the support box 4, this sleeve being immobilized relative to the guide path 3 by a nut 11 screwed onto the threaded free end 9 of the rods 7. Thus, the springs 5, which are threaded on the sleeve 10, are held with a certain compression between the nut 11 and the inner face of the wall of the support box on which the guide path 3 is mounted. In this way, the springs exert a certain traction on the guide path 3 in a direction perpendicular to the longitudinal axis of the latter.
Afin d'assurer l'étanchéité entre le caisson de support 4 et le chemin de guidage 3, indépendamment de la distance qui ies sépare les uns des autres, une bande souple d'étanchéite 12, par exemple réalisée en caoutchouc ou en plastique, est prévue entre le cnemm de guidage 3 et le caisson de support 4.In order to seal between the support box 4 and the guide path 3, independently from the distance which separates them from each other, a flexible sealing strip 12, for example made of rubber or plastic, is provided between the guide cnemm 3 and the support box 4.
On des bords longitudinaux latéraux 13 de la bande d'étanchéite 12 présente des orifices qui sont traversés par les tiges 7. Ces dernières sont fixées â des distances régulières les unes par rapport aux autres sur le dos 14 des chemins de guidage 3, comme montré clairement à la figure 1. Ce bord 13 est maintenu contre le dos 14 du chemin de guidage 3 par l'intermédiaire de l'extrémité libre des manchons 10 dirigée vers ce dos, qui s'applique autour des orifices précités contre ce bord 13.On the longitudinal side edges 13 of the sealing strip 12 has orifices which are crossed by the rods 7. The latter are fixed at regular distances from each other on the back 14 of the guide tracks 3, as shown clearly in FIG. 1. This edge 13 is held against the back 14 of the guide path 3 via the free end of the sleeves 10 directed towards this back, which is applied around the abovementioned orifices against this edge 13.
De plus, afin de permettre à la bande d'étanchéite de suivre les variations de 1 'écartement entre le chemin de guidage 3 et le caisson de support 4 sur lequel il est monte, la bande d'étanchéite 12 forme une boucle 15 entre le chemin de guidage 3 et le caisson de support 4. Ainsi, les tiges 7 traversent librement la branche 16 de la boucle 15 située du cote du caisson de support 4, de manière à ce que celle-ci puisse se déplacer librement sur le manchon 10 enfile sur la tige 7. L'autre branche 17 présente le bord libre 13 et est fixée contre le dos 14 du chemin de guidage par l'extrémité libre du manchon 10, comme déjà décrit ci-dessus.In addition, in order to allow the sealing strip to follow the variations in spacing between the guide path 3 and the support box 4 on which it is mounted, the sealing strip 12 forms a loop 15 between the guide path 3 and the support box 4. Thus, the rods 7 freely cross the branch 16 of the loop 15 located on the side of the support box 4, so that it can move freely on the sleeve 10 threads on the rod 7. The other branch 17 has the free edge 13 and is fixed against the back 14 of the guide path by the free end of the sleeve 10, as already described above.
Dans la forme de réalisation particulière du dispositif de fermeture suivant l'invention, illustrée par les figures 1 à 3, les bords latéraux saillants 2 du rideau 1 sont formés par une succession de petits blocs juxtaposés identiques 2', réalisés de préférence en une matière plastique dure, situés dans le prolongement les uns des autres et à proximité les uns des autres, en étant relies d'une manière fie ibie entre eux, par exemple comme les bioc ets d'une fermeture à glissière connue en soi. En fait, ces biochets peuvent être le plus près possible les uns des autres pour autant ' que les bords latéraux 2 restent suffisamment flexibles pour permettre l'enroulement du rideau autour d'un axe.In the particular embodiment of the closure device according to the invention, illustrated by FIGS. 1 to 3, the projecting lateral edges 2 of the curtain 1 are formed by a succession of small juxtaposed identical blocks 2 ′, preferably made of a material hard plastic, located in the extension of each other and close to each other, being connected in a solid manner between them, for example as the bioc ets of a zipper known per se. In fact, these biochets can be as close as possible from each other so far 'the lateral edges 2 remain sufficiently flexible to allow the winding of the curtain around an axis.
Toujours dans cette forme de réalisation particulière du dispositif de fermeture suivant l'invention, les chemins de guidage 3 présentent chacun deux rebords longitudinaux 18 et 19 situés de part et d'autre du rideau 1 et dirigés l'un vers l'autre suivant une direction sensiblement perpendiculaire au rideau. Ainsi, ces chemins de guidage 3 entourent le bord saillant 2 du rideau 1.Still in this particular embodiment of the closure device according to the invention, the guide tracks 3 each have two longitudinal edges 18 and 19 located on either side of the curtain 1 and directed towards each other in a direction substantially perpendicular to the curtain. Thus, these guide paths 3 surround the projecting edge 2 of the curtain 1.
Ces deux rebords longitudinaux 18 et 19, qui retiennent donc le bord saillant 2 du rideau 1 dans les chemins de guidage, font partie de deux profilés sépares en une matière quelque peu élastique 20 et 21, qui présentent chacun une section transversale ayant une allure sensiblement en forme de Z. Une des deux ailes de ces profilés 20 et 21 forme le rebord longitudinal précité, respectivement 18 et 19, l'autre aile 22, respectivement 23, formant la base de ces profilés, qui est maintenue dans un profilé métallique rigide en ϋ 24, dont les ailes présentent également des rebords 25 et 26 dirigés l'un vers l'autre. Les deux profilés en Z 20 et 21 sont maintenus dans le profilé en U 24 par une tige intercalaire 27 serrée dans ce dernier entre les bases de ces deux profilés 20 et 21 et une tige intercalaire 31 de part et d'autre de ces profilés et l'aile voisine du profilé en ϋ. Ce dernier est alors, à son tour, maintenu dans un profilé de support 28, également en ϋ, dont les ailes présentent des rebords orientés l'un vers l'autre. Des oarrettes 29, présentant une section en L et réalisées de préférence également en une matière relativement élastique, par exemple de la même nature que celle des profiles en Z 20 et 21, sont engagées dans des joints prévus entre les rebords 30 du profilé de support 28 et les profiles en Z pour s'appuyer latéralement contre ces derniers et ainsi contrôler leur flexibilité latérale.These two longitudinal edges 18 and 19, which therefore retain the projecting edge 2 of the curtain 1 in the guide tracks, are part of two separate sections of somewhat elastic material 20 and 21, which each have a cross section having a substantially appearance Z-shaped. One of the two wings of these profiles 20 and 21 forms the abovementioned longitudinal edge, respectively 18 and 19, the other wing 22, respectively 23, forming the base of these profiles, which is held in a rigid metal profile. in ϋ 24, the wings of which also have flanges 25 and 26 directed towards each other. The two Z-shaped profiles 20 and 21 are held in the U-shaped profile 24 by an intermediate rod 27 clamped in the latter between the bases of these two profiles 20 and 21 and an intermediate rod 31 on either side of these profiles and the wing adjacent to the en profile. The latter is then, in turn, held in a support profile 28, also in ϋ, the wings of which have edges oriented towards one another. Tabs 29, having an L-shaped section and made of preferably also made of a relatively elastic material, for example of the same nature as that of the Z profiles 20 and 21, are engaged in seals provided between the flanges 30 of the support profile 28 and the Z profiles to bear laterally against these and thus control their lateral flexibility.
Le fait que ies profilés en Z 20 et 21 qui maintiennent les ioords saillants 2 du rideau 1 présentent une certaine élasticité permet à ces bords de se dégager du chemin de guidage 3 lorsqu'une certaine force est appliquée sur le plan du rideau .The fact that the Z-shaped sections 20 and 21 which hold the projecting ioords 2 of the curtain 1 have a certain elasticity allows these edges to disengage from the guide path 3 when a certain force is applied to the plane of the curtain.
Des contacts 32 peuvent par exemple être agences entre le chemin de guidage 3 et le support 4 pour permettre de détecter le moment où le bord saillant 2 du rideau 1 se serait dégagé du chemin de guidage et/ou que la force 6 exercée sur le rideau 1 dépasse une limite déterminée. Ces contacts 32 sont alors de préférence branchés dans un circuit d'alarme pour, par exemple, mettre hors service et bloquer le rideau dans son mouvement d'enroulement ou de déroulement, ou simplement pour mettre en action un appareil d'avertissement. Ces contacts pourraient également être prévus à 1 ' intérieur du caisson et coopérer avec ies tiges 7.Contacts 32 can, for example, be arranged between the guide path 3 and the support 4 in order to detect the moment when the projecting edge 2 of the curtain 1 is released from the guide path and / or when the force 6 exerted on the curtain 1 exceeds a specified limit. These contacts 32 are then preferably connected to an alarm circuit for, for example, putting out of service and blocking the curtain in its winding or unwinding movement, or simply to activate a warning device. These contacts could also be provided inside the box and cooperate with the rods 7.
Dans une autre forme de réalisation de l'invention, des moyens peuvent avantageusement être prévus pour intercepter la force 6 agissant sur le rideau au moment ou celui-ci atteint une certaine limite, sans que le bord saillant 2 se dégage de ses chemins de guidage 3. Ainsi, le bord saillant 2 pourrait par exemple être fixé au rideau par des moyens de faible résistance s'étendant entre le rideau et ses bords saillants 2. Ces moyens pourraient par exemple être formés par une bride et des goupilles présentant une résistance calculée de sorte que ces goupilles puissent casser dès que la force 6 atteint une* limite prédéterminée. On pourrait également prévoir entre le bord saillant 2 et le plan même du rideau une zone de faible résistance qui puisse céder au moment où la force précitée agissant sur le plan du rideau atteint un certain niveau qui soit inférieur à la force nécessaire pour dégager le bord saillant 2 du son chemin de guidage.In another embodiment of the invention, means can advantageously be provided for intercepting the force 6 acting on the curtain when it reaches a certain limit, without the projecting edge 2 being released from its guide paths 3. Thus, the projecting edge 2 could for example be fixed to the curtain by means of low resistance extending between the curtain and its projecting edges 2. These means could for example be formed by a flange and pins having a resistance calculated so that these pins can break as soon as the force 6 reaches a predetermined limit. It would also be possible to provide, between the projecting edge 2 and the plane of the curtain, a zone of low resistance which can yield when the aforementioned force acting on the plane of the curtain reaches a certain level which is less than the force necessary to release the edge protruding 2 of its guide path.
La forme de réalisation du dispositif suivant l'invention montrée à la figure 4 diffère essentiellement par rapport à celie de la figure 2 par le fait que les moyens élastiques sont constitués par des éléments en mousse sensiblement élastique 5, telle que de la mousse de polyuréthane ou de latex. Ces éléments 5 s'étendent sur toute la longueur du chemin de guidage 3 et permettent ainsi d'assurer l'étanchéité entre ce dernier et le support 4 sur lequel il est monté, sans qu'il soit nécessaire d'y prévoir une bande supplémentaire d'étanchéite, comme dans la précédente forme de réalisation. Ces éléments en mousse 5 sont constitués de barrettes de section rectangulaire et sont agencés dans un profilé en U 34 fixé par soudure contre la face extérieure du caisson de support 4. Les ailes latérales de ce profilé 34 présentent des rebords 35 dirigés l'un vers l'autre contre lesquels est appliquée une des faces 38 des éléments en mousse 5.The embodiment of the device according to the invention shown in Figure 4 differs essentially from that of Figure 2 in that the elastic means are constituted by elements of substantially elastic foam 5, such as polyurethane foam or latex. These elements 5 extend over the entire length of the guide path 3 and thus make it possible to seal between the latter and the support 4 on which it is mounted, without the need for an additional strip. sealing, as in the previous embodiment. These foam elements 5 consist of bars of rectangular section and are arranged in a U-shaped profile 34 fixed by welding against the outside face of the support box 4. The lateral wings of this profile 34 have flanges 35 directed one towards the other against which one of the faces 38 of the foam elements 5 is applied.
Par ailleurs, les profilés en Z 20 et 21 sont fixés sur toute leur longueur d'une manière démontable entre deux plaques identiques 37, dont un des bords longitudinaux présente l'allure d'un crochet (25} et maintien les profilés 20 et 21 en place, le bord longitudinal opposé étant pourvu de pattes d'appui 36 s'appliquant contre la face 39 des éléments en mousse 5 opposée à celle s ' appuyant contre les rebords 35 du profilé 34.Furthermore, the Z profiles 20 and 21 are fixed over their entire length in a removable manner between two identical plates 37, one of the longitudinal edges of which has the appearance of a hook (25} and maintains the profiles 20 and 21 in place, the opposite longitudinal edge being provided with support tabs 36 pressing against the face 39 of the foam elements 5 opposite to that pressing against the flanges 35 of the profile 34.
On plat intercalaire 27 s'étend entre ies deux plaques 35 et ies cases des profilés 20 et 21 et détermine la distance séparant ces derniers les uns des autres. De plus, les bords en forme de crochet 25 sont appliqués d'une manière élastiquement réglable contre les profilés 20 et 21 afin de pouvoir contrôler ainsi la force agissant par ces derniers sur les bords 2 du rideau 1, particulièrement la force qui est nécessaire pour dégager les bords 2 du chemin de guidage 3.The intermediate plate 27 extends between the two plates 35 and the boxes of the sections 20 and 21 and determines the distance separating the latter from each other. In addition, the hook-shaped edges 25 are applied in an elastically adjustable manner against the profiles 20 and 21 so as to be able to thus control the force acting by the latter on the edges 2 of the curtain 1, particularly the force which is necessary for clear the edges 2 of the guide path 3.
A cet effet, les bords libres 40 des crochets 25 sont légèrement inclinés en s'appliquant élastiquement contre les profilés 20 et 21 et un boulon traversant les plaques 37 et le plat intercalaire 31 permet, au moyen d'un écrou 42 vissé sur ce boulon 41, de régler la pression exercée par ces bords libres 40 sur les profilés 20 et 21.For this purpose, the free edges 40 of the hooks 25 are slightly inclined by applying elastically against the profiles 20 and 21 and a bolt passing through the plates 37 and the intermediate plate 31 allows, by means of a nut 42 screwed on this bolt 41, to adjust the pressure exerted by these free edges 40 on the sections 20 and 21.
La forme de réalisation du dispositif suivant l'invention telle que représentée à la figure 5 se distingue essentiellement par rapport â celle de la figure 4 par le fait que les moyens élastiques sont constitués par deux bandes en matière élastique 5, telle que du caoutchouc ou un élasto ere plastique, qui sont soumises à une force de traction, alors que, dans la forme de réalisation suivant la figure 4, les barrettes de mousse 5 sont soumises à une force de compression. Un des bords latéraux de ces bandes 5 présente un bourrelet 43 maintenu dans une goutière 44 des plaques 37 appliquées contre le plat intercalaire 31. L'autre bord latéral de ces bandes est replié contre la face extérieure du caisson de support 4 et est maintenu contre ce dernier par des boulons 45 régulièrement espacés. Ces bandes 5 qui s'étendent sur toute la longueur du chemin de guidage 3 forment donc en même temps un joint d'étanchéite entre ce dernier et le caisson de support 4.The embodiment of the device according to the invention as shown in FIG. 5 differs essentially from that of FIG. 4 by the fact that the elastic means consist of two bands of elastic material 5, such as rubber or a plastic elasto, which are subjected to a tensile force, whereas, in the embodiment according to FIG. 4, the foam strips 5 are subjected to a compressive force. One of the lateral edges of these strips 5 has a bead 43 held in a groove 44 of the plates 37 applied against the intermediate plate 31. The other lateral edge of these strips is folded against the outside face of the support box 4 and is held against the latter by regularly spaced 45 bolts. These strips 5 which extend over the entire length of the guide path 3 therefore form at the same time a seal between the latter and the support box 4.
Il peut également être important de prévoir des moyens d'arrêt permettant de limiter le déplacement des chemins de guidage 3 dans la direction du rideau 1 lorsqu'une force 6 est exercée sur ce dernier.It may also be important to provide stop means making it possible to limit the displacement of the guide tracks 3 in the direction of the curtain 1 when a force 6 is exerted on the latter.
Dans le cas de la forme de réalisation suivant la figure 2, l'arrêt est automatiquement obtenu au moment ou toutes les spires du ressort sont appliquées l'un contre l'autre. Si les moyens élastiques sont formés d'éléments en mousse, l'arrêt est obtenu lorsque ces éléments sont entièrement comprimes. Si on fait usage de bandes élastiques, qui sont donc soumises à une traction, il pourrait être important d'incorporer dans ces dernières une armature permettant de limiter l'allongement de la bande suivant la direction de la traction.In the case of the embodiment according to Figure 2, the stop is automatically obtained when all the turns of the spring are applied against each other. If the elastic means are formed of foam elements, the stop is obtained when these elements are fully compressed. If elastic bands are used, which are therefore subjected to traction, it could be important to incorporate therein an armature making it possible to limit the elongation of the band in the direction of traction.
Un des avantages des formes de réalisation suivant ies figures 4 et 5 est que toutes les accessoires des chemins de guidage 3 se situent à l'extérieur du support 4, de sorte que ce dernier pourrait, le cas échéant, être constitue d'une paroi pleine, telle qu'une colonne en béton.One of the advantages of the embodiments according to FIGS. 4 and 5 is that all the accessories of the guide tracks 3 are located outside the support 4, so that the latter could, if necessary, be constituted by a wall full, such as a concrete column.
Grâce au fait que les chemins de guidage 3 sont montés sur leur support 4 par l'intermédiaire de moyens élastiques, pratiquement aucun ajustement n'est nécessaire sur chantier, le montage complet des chemins de guidage sur leurs supports correspondants pouvant se réaliser entièrement en usine.Thanks to the fact that the guide tracks 3 are mounted on their support 4 by means of elastic means, practically no adjustment is necessary on site, the complete mounting of the guide tracks on their corresponding supports being able to be carried out entirely in the factory. .
Par ailleurs, par la présence des moyens élastiques, le rideau est constamment sous une tension horizontale contrôlée et des dilatations ou rétrécissements du rideau qui pourraient se produire suite à des fluctuations de température seront automatiquement compensés par les moyens élastiques. Ceci sera également le cas pour des variations de distance entre ies chemins de guidage de part et d'autre du rideau, p.e. si ces derniers ne sont pas parfai-tement parallèles.Furthermore, by the presence of the elastic means, the curtain is constantly under a controlled horizontal tension and expansions or shrinkages of the curtain which could occur following temperature fluctuations will be automatically compensated by the elastic means. This will also be the case for variations of distance between the guide paths on either side of the curtain, eg if the latter are not perfectly parallel.
Grâce au fait que les chemins de guidage peuvent pivoter autour d'un axe parallèle à leur axe longitudinal, la traction exercée par le rideau 1, par l'intermédiaire des bords 2, sera toujours repartie symétriquement sur les deux profilés 20 et 21, notamment sur les deux rebords respectivement 18 et 19 de ces derniers, et ceci toujours suivant une direction sensiblement parallèle à l'âme 34 de ces deux profilés 20 et 21.Thanks to the fact that the guide tracks can pivot around an axis parallel to their longitudinal axis, the traction exerted by the curtain 1, via the edges 2, will always be distributed symmetrically on the two sections 20 and 21, in particular on the two flanges 18 and 19 respectively of the latter, and this always in a direction substantially parallel to the core 34 of these two sections 20 and 21.
Ainsi, il sera parfaitement possible de déterminer d:une manière assez rigoureuse ies caractéristiques physiques auxquelles les profilés 20 et 2! doivent repondre pour que le bord 2 puisse se dégager de ses chemins de guidage 3 à partir d'une force déterminée appliquée sur le rideau 1. De plus, grâce au fait que la force de frottement du bord 2 sera repartie symétriquement sur les deux profilés 18 et 19, l'usure tant du bord que des profilés sera uniforme et réduite à un strict minimum, ce qui augmentera sensiblement la longévité de ces éléments.This will make it perfectly possible to determine: a rather rigorous ies physical characteristics to which profiles 20 and 2! must respond so that the edge 2 can disengage from its guide paths 3 from a determined force applied to the curtain 1. In addition, thanks to the fact that the frictional force of the edge 2 will be distributed symmetrically on the two profiles 18 and 19, the wear on both the edge and the profiles will be uniform and reduced to a strict minimum, which will significantly increase the longevity of these elements.
Il doit être entendu que l'invention n'est nullement limitée à la forme de réalisation particulière décrite ci-dessus • et représentée aux figures du dispositif suivant l'invention et que bien des variantes peuvent être envisagées sans sortir de cette invention ; c'est ainsi que, pour certaines applications ou types de dispositif, le chemin de guidage 3 pourrait être monté sur le support 4 par l'intermédiaire d'une charnière ou d'une série de charnières successives, dont l'axe de rotation est parallèle a l'axe de ce chemin de guidage.It should be understood that the invention is in no way limited to the particular embodiment described above • and shown in the figures of the device according to the invention and that many variants can be envisaged without departing from this invention; this is how, for certain applications or types of device, the guide path 3 could be mounted on the support 4 by means of a hinge or a series of successive hinges, the axis of rotation of which is parallel to the axis of this guide path.
Par ailleurs, dans d'autres cas, ces chemins de guidage pourraient être montés sur leurs supports de manière à ne pouvoir subir qu'une translation -suivant le plan du rideau en position fermée, les moyens élastiques ne permettraient alors pas le pivotement du chemin de guidage.By the way, in other cases, these paths guide could be mounted on their supports so as to be able to undergo only a translation - following the plane of the curtain in the closed position, the elastic means would then not allow the pivoting of the guide path.
Il va toutefois de soi qu'une préférence prononcée est donnée à un système dans lequel le chemin de guidage peut simultanément subir un pivotement et une translation élastique.It goes without saying, however, that a pronounced preference is given to a system in which the guide path can simultaneously undergo pivoting and elastic translation.
Dans encore d'autres cas, le bord 2 du rideau 1 pourrait être prévu de moyens de guidage espacés, tels que des galets ou patins s'étendant à une certaine distance l'un de l'autre sur le bord du rideau. Il ne s'agirait donc pas d'un bord saillant sensiblement continu.In still other cases, the edge 2 of the curtain 1 could be provided with spaced guide means, such as rollers or pads extending at a certain distance from each other on the edge of the curtain. It would therefore not be a substantially continuous projecting edge.
Enfin, suivant une forme de réalisation particulière de l'invention le rideau 1 est constitué d'une bâche et présente au moins une zone sensiblement élastique 50, formée par exemple par une bande en une matière élastique montrée schè atiquement sur la figure 1, s'étendant sur toute la longueur du rideau 1, suivant la direction de ses bords latéraux. Cette zone 50 peut en principe être située à n'importe quel endroit du rideau, mais pour de raisons de symétrie, p.e. elle se trouvera de préférence à proximité de chacun de ses bords latéraux 2 ou éventuellement au milieu. On pourrait toutefois également prévoir une seule zone élastique à proximité d'un des deux bords latéraux 2. Dans une variante, tout le rideau pourrait être réalisé en une matière sensiblement élastique. Les chemins de guidage 3 pourraient être montés â pivotement ou être fixe sur le support 4. On pourrait même combiner ces dernières formes de réalisation avec celles où les chemins de guidage 3 sont montes d'une manière élastique sur le support 4. Dans le cadre de la présente invention, le rideau est de préférence constitué d'une bâche continue entièrement souple, en opposition aux rideaux qui comprennent à des distances régulières des barres horizontales légèrement flexibles ou non, qui assurent le guidage latéral du rideau. Finally, according to a particular embodiment of the invention, the curtain 1 consists of a tarpaulin and has at least one substantially elastic zone 50, formed for example by a strip of elastic material shown diagrammatically in FIG. 1, s 'extending over the entire length of the curtain 1, in the direction of its lateral edges. This area 50 can in principle be located anywhere on the curtain, but for reasons of symmetry, eg it will preferably be near each of its lateral edges 2 or possibly in the middle. However, a single elastic zone could also be provided near one of the two lateral edges 2. In a variant, the entire curtain could be made of a substantially elastic material. The guide tracks 3 could be pivotally mounted or be fixed on the support 4. These latter embodiments could even be combined with those where the guide tracks 3 are resiliently mounted on the support 4. In the context of the present invention, the curtain preferably consists of a fully flexible continuous sheet, in contrast to the curtains which comprise at regular distances horizontal bars which are slightly flexible or not, which provide lateral guidance of the curtain.
