Description

L'invention est relative à un dispositif à rideau monté sur un arbre autour duquel ce rideau peut être enroulé vers une position d'ouverture et dont il peut se dérouler vers une position de fermeture, une roue d'entraînement étant fixée coaxialement sur cet arbre, de préférence de part et d'autre du rideau, et coopérant avec ce dernier d'une manière telle à pouvoir le déplacer entre ces deux positions.The invention relates to a curtain device mounted on a shaft around which this curtain can be wound to an open position and which can be unwound towards a closed position, a drive wheel being fixed coaxially on this shaft , preferably on both sides of the curtain, and cooperating with the latter in such a way as to be able to move it between these two positions.

Les dispositifs connus de ce genre, notamment par les documents US 5 655 591 , US 5392836 , US 5 353 859 , US 4 690 194 , DE 32 45 009 , WO 99/19590 A , GB 1 588 438 A , DE 198 20 933 A et EP 1 298 264 A , exigent que le rideau soit tendu durant tout le parcours entre sa position d'ouverture et sa position de fermeture. Ceci a comme conséquence que ces dispositifs sont d'une construction très complexe et très coûteuse par la présence de ressorts, poulies de renvoi, démultiplicateurs etc. qui nécessitent généralement un réglage très précis pour permettre un bon fonctionnement et qui sont sujets a une forte usure et des réparations fréquents, surtout en cas d'accrochage du rideau. Le document WO-03 6801 montre un disposif à rideau selon le préambule de la revendication 1.Known devices of this kind, including documents US 5,655,591 , US 5392836 , US 5,353,859 , US 4,690,194 , DE 32 45 009 , WO 99/19590 A , GB 1 588 438 A , DE 198 20 933 A and EP 1 298 264 A require the curtain to be stretched all the way between its open position and its closed position. This has the consequence that these devices are of a very complex and very expensive construction by the presence of springs, return pulleys, gear reducers etc. which generally require very precise adjustment to allow proper operation and which are subject to heavy wear and frequent repairs, especially when the curtain is fastened. The document WO-03 6801 shows a curtain device according to the preamble of claim 1.

Un des buts essentiels de la présente invention est de remédier à ces inconvénients en présentant un dispositif d'une conception très simple et efficace qui est économiquement justifié et qui permet le développement de nombreuses variantes pour différentes applications. Ainsi, il est possible de concevoir des variantes permettant d'obtenir une fermeture étanche, par exemple, pour frigos, conteneurs, silos, véhicules utilitaires, tels que camions, bateaux, wagons, des variantes dans lesquelles le rideau s'étend horizontalement ou obliquement dans sa position de fermeture, etc.One of the essential aims of the present invention is to overcome these disadvantages by having a device of a very simple and efficient design which is economically justified and which allows the development of numerous variants for different applications. Thus, it is possible to design variants for obtaining a seal, for example, for refrigerators, containers, silos, commercial vehicles, such as trucks, boats, wagons, variants in which the curtain extends horizontally or obliquely. in its closed position, etc.

A cet effet, le dispositif, suivant l'invention, comprend un organe de commande oblong flexible dans le sens de sa longueur coopérant avec la roue d'entraînement, cet organe étant agencé de manière à permettre, d'une part, de déplacer le rideau entre sa position d'ouverture et sa position de fermeture indépendamment du mou qui se serait formé dans le rideau et, d'autre part, de le déplacer le long d'au moins un des bords latéraux du rideau et agir sur la zone de ce dernier opposée à celle dirigée du côté de l'arbre précité également indépendamment d'un mou éventuel dans le rideau.For this purpose, the device, according to the invention, comprises an oblong control member flexible in the direction of its length cooperating with the drive wheel, this member being arranged so as, on the one hand, to move the curtain between its open position and its closed position independently of the slack that would have formed in the curtain and, secondly, to move it along at least one of the lateral edges of the curtain and act on the the latter opposite to that directed towards the aforementioned shaft also independently of a possible slack in the curtain.

Suivant l'invention, le diamètre primitif de la roue d'entraînement est, d'une part, inférieur au diamètre de la partie enroulée du rideau dans sa position d'ouverture et, d'autre part, supérieur au diamètre de l'arbre précité ou de la partie enroulée du rideau dans sa position de fermeture.According to the invention, the pitch diameter of the drive wheel is, on the one hand, smaller than the diameter of the wound portion of the curtain in its position opening and, on the other hand, greater than the diameter of the aforementioned shaft or the curled portion of the curtain in its closed position.

L'organe de commande et son montage dans le dispositif suivant l'invention sont donc tels à permettre la formation de mou dans le rideau lors de son déplacement, sans que ceci puisse gêner son fonctionnement.The control member and its mounting in the device according to the invention are such as to allow the formation of slack in the curtain during its movement, without this may hinder its operation.

Ceci n'est pas possible avec les dispositifs suivant l'état antérieur de la technique dans lesquels, au contraire, tout est mis en oeuvre pour éviter du mou. De cette exigence découle justement la construction complexe de ces dispositifs connus.This is not possible with devices according to the prior art in which, on the contrary, everything is implemented to avoid slack. This requirement stems precisely from the complex construction of these known devices.

Dans le cadre de la présente invention, il faut comprendre par l'expression 'diamètre primitif, la distance parcourue par l'organe de commande à partir de la roue d'entraînement pendant un tour de cette dernière divisée par le nombre π.In the context of the present invention, it should be understood by the expression "pitch diameter, the distance traveled by the control member from the drive wheel during a turn of the latter divided by the number π.

D'une façon générale, la présente invention est relative à un dispositif à rideau enroulable coopérant avec des moyens d'entraînement permettant de déplacer le rideau entre une position d'ouverture et une position de fermeture. Il est important de noter que le rideau est enroulable autour d'un arbre qui est commun avec celui des moyens d'entraînement. Le rideau est généralement destiné à la fermeture d'une baie dans une paroi ou toute autre ouverture, au recouvrement d'une piscine, d'un espace telle qu'une véranda, à former un écran, p.e. devant une fenêtre, etc. Cette énumération n'est bien entendue non limitative.In general, the present invention relates to a roll-up curtain device cooperating with drive means for moving the curtain between an open position and a closed position. It is important to note that the curtain is rollable around a shaft that is common with that of the drive means. The curtain is generally intended for closing a bay in a wall or other opening, covering a swimming pool, a space such as a veranda, forming a screen, eg in front of a window, etc. This enumeration is of course not exhaustive.

Par le mot "rideau", il y a lieu de comprendre, dans le cadre de la présente invention, tout panneau ou surface plane d'une matière au moins partiellement souple, flexible, semi-rigide, ou avec un ou plusieurs raidisseurs, tel qu'une bâche, une bande en matière plastique, une toile ou tôle métallique, un treillis, etc., pouvant s'enrouler autour d'un arbre.By the word "curtain", it should be understood, in the context of the present invention, any panel or flat surface of a material at least partially flexible, flexible, semi-rigid, or with one or more stiffeners, such a tarpaulin, a strip of plastic material, a canvas or sheet metal, a lattice, etc., which can be wrapped around a tree.

Il y a, toutefois, lieu de noter qu'une préférence prononcée est donnée aux rideaux souples formés, par exemple, par une bâche, de sorte que la description donnée ci-après sera limitée à un dispositif dans lequel le rideau est formé par une bâche.It should be noted, however, that a pronounced preference is given to flexible curtains formed, for example, by a tarpaulin, so that the description given hereinafter will be limited to a device in which the curtain is formed by a tarpaulin.

Une première forme de réalisation du dispositif à rideau est représentée dans les figures 1 à 6. Ce dispositif comprend un rideau 1, s'enroulant et se déroulant verticalement, qui est fixé avec son bord supérieur à un arbre 2 prévu au-dessus d'une baie 3 et s'étendant sur sensiblement toute la largeur de cette dernière. Le rideau 1 peut être déplacé entre une position d'ouverture, comme représentée dans les figures 1 et 2, et une position de fermeture, comme représentée dans la figure 5. Dans la position d'ouverture, le rideau 1 est presque entièrement enroulé autour l'arbre 2 et forme un rouleau 15, tandis que dans la position de fermeture, le rideau 1 est pratiquement complètement déroulé de cet arbre 2. Dans certains cas, le rideau 1 peut être entièrement enroulé autour de l'arbre 2, de manière à maintenir un maximum d'espace libre en dessous du rideau dans sa position d'ouverture.A first embodiment of the curtain device is shown in Figures 1 to 6 . This device comprises a curtain 1, winding and unrolling vertically, which is fixed with its upper edge to a shaft 2 provided above a bay 3 and extending over substantially the entire width of the latter. The curtain 1 can be moved between an open position, as shown in the figures 1 and 2 , and a closed position, as shown in the figure 5 . In the open position, the curtain 1 is almost completely wound around the shaft 2 and forms a roller 15, whereas in the closed position, the curtain 1 is practically completely unrolled from this shaft 2. In some cases, the curtain 1 curtain 1 can be fully wrapped around the shaft 2, so as to maintain a maximum of free space below the curtain in its open position.

Lors du déplacement du rideau 1 vers sa position d'ouverture ou de fermeture, les bords latéraux 4 du rideau 1, qui présentent un bourrelet saillant par rapport au plan du rideau, sont guidés dans des glissières 5 montées de part et d'autre de la baie 3 sur sensiblement toute la hauteur de cette dernière.When moving the curtain 1 towards its open or closed position, the lateral edges 4 of the curtain 1, which have a bead protruding from the plane of the curtain, are guided in slides 5 mounted on either side of the curtain the bay 3 over substantially the entire height of the latter.

De chacun des côtés latéraux du rideau 1 est prévue une roue d'entraînement 7, faisant partie des moyens d'entraînement précités, qui est fixée coaxialement sur ledit arbre 2, de sorte que cet arbre 2 et cette roue d'entraînement 7 se déplacent à la même vitesse angulaire. Chacune de ces roues d'entraînement 7 coopère avec un organe de commande 11 permettant de déplacer le rideau 1 vers sa position de fermeture et qui, suivant l'invention, est monté librement par rapport au rideau 1, notamment par rapport au bord libre 8 de ce dernier sur lequel il peut effectuer une force de poussée.On each of the lateral sides of the curtain 1 is provided a drive wheel 7, forming part of the abovementioned driving means, which is fixed coaxially on said shaft 2, so that this shaft 2 and this drive wheel 7 move at the same angular velocity. Each of these driving wheels 7 cooperates with a control member 11 for moving the curtain 1 to its closed position and which, according to the invention, is freely mounted relative to the curtain 1, in particular with respect to the free edge 8 of the latter on which it can perform a pushing force.

La roue d'entraînement 7 est, en particulier, constituée d'une roue dentée, tandis que l'organe de commande 11 est formé par une bande oblongue étroite et flexible, mais incompressible dans le sens de sa longueur, telle qu'une lanière. Cette bande est pourvue d'une succession d'évidements 10 qui sont situés à la même distance constante l'une par rapport à l'autre suivant sa direction longitudinale et qui engrènent avec des dents 9 prévues sur les roues d'entraînement 7 à une distance constante l'une par rapport à l'autre suivant le pourtour d'un cercle dont le centre se situe sur l'axe 6 des roues d'entraînement 7. Dans les figures 2 à 5, ces dents et évidements n'ont, pour la clarté, pas été représentés.The drive wheel 7 is, in particular, made of a toothed wheel, while the control member 11 is formed by a narrow oblong band and flexible, but incompressible in the direction of its length, such as a thong . This strip is provided with a succession of recesses 10 which are situated at the same constant distance with respect to each other in its longitudinal direction and which mesh with teeth 9 provided on the drive wheels 7 at a distance from one another. constant distance relative to each other around the circumference of a circle whose center is located on the axis 6 of the drive wheels 7. In the Figures 2 to 5 these teeth and recesses have not, for clarity, been represented.

Le diamètre d0 des roues d'entraînement 7, en particulier le diamètre primitif de ces roues, est inférieur au diamètre d1 du rouleau 15 lorsque le rideau 1 est dans sa position d'ouverture et supérieur au diamètre d2 de l'arbre 2 ou de la partie encore enroulée du rideau 1 dans la position de fermeture. En effet, le diamètre d2 est normalement légèrement supérieur au diamètre de l'arbre 2 par le fait que, dans la position de fermeture, une petite partie du rideau 1 reste généralement enroulée sur l'arbre 2.The diameter d 0 of the drive wheels 7, in particular the pitch diameter of these wheels, is smaller than the diameter d 1 of the roller 15 when the curtain 1 is in its open position and greater than the diameter d 2 of the shaft. 2 or the still wound portion of the curtain 1 in the closed position. Indeed, the diameter d 2 is normally slightly greater than the diameter of the shaft 2 in that, in the closed position, a small portion of the curtain 1 generally remains wound on the shaft 2.

Le diamètre d0 est, de préférence, égal ou supérieur à la moitié de la somme des diamètres d1 et d2.The diameter d 0 is preferably equal to or greater than half the sum of the diameters d 1 and d 2 .

Dans la position d'ouverture, le rideau 1 est pratiquement entièrement enroulé autour de l'arbre 2 et forme des spires successives 14, comme représenté dans la figure 2. Dans cette position, chacune des extrémités du bord inférieur 8 du rideau 1, opposé à celui monté sur l'arbre 2, est maintenue dans les glissières 5.In the open position, the curtain 1 is substantially completely wound around the shaft 2 and forms successive turns 14, as shown in FIG. figure 2 . In this position, each of the ends of the lower edge 8 of the curtain 1, opposite that mounted on the shaft 2, is maintained in the slides 5.

Les organes de commande 11, dont l'extrémité inférieure 16 est, dans la position d'ouverture, maintenue dans la partie supérieure des glissières 5, sont également guidés dans les glissières respectives 5 lors de l'ouverture et la fermeture du rideau 1, comme ce sera décrit plus en détail en rapport avec la figure 6.The control members 11, whose lower end 16 is, in the open position, held in the upper part of the slides 5, are also guided in the respective slides 5 during the opening and closing of the curtain 1, as will be described in more detail in relation to the figure 6 .

Dans la position d'ouverture du rideau 1, comme montré à la figure 2, son bord inférieur 8 se trouve à une distance X en dessous de l'extrémité libre 16 de l'organe de commande correspondant 11. Cette distance permet une certaine tolérance dans la construction et le réglage du dispositif suivant l'invention. Il est possible de calculer les dimensions de la roue d'entraînement et de l'organe de commande en fonction du déplacement du rideau d'une manière telle à réduire cette distance à zéro.In the open position of the curtain 1, as shown in FIG. figure 2 its lower edge 8 is at a distance X below the free end 16 of the corresponding control member 11. This distance allows a certain tolerance in the construction and adjustment of the device according to the invention. It is possible to calculating the dimensions of the drive wheel and the control member according to the displacement of the curtain in such a way as to reduce this distance to zero.

Lorsqu'on veut déplacer le rideau 1 vers sa position de fermeture à partir de sa position d'ouverture, l'arbre 2 est entraîné par un moteur électrique 13. Le rouleau 15, formé par les spires 14 du rideau 1, et les roues d'entraînement 7, qui sont fixées sur l'arbre 2, sont, par conséquent, soumis au même mouvement de rotation. Le rideau 1, qui est maintenu par ses bords latéraux 4 dans les glissières 5, est freiné et, dans certains cas, même bloqué dans son déplacement vers sa position de fermeture par suite du frottement qui existe nécessairement entre ces bords 4 et les glissières 5. De ceci résulte que, lors de du démarrage de la fermeture du rideau, les spires 14 du rouleau s'agrandissent graduellement et se détachent l'une de l'autre en formant du mou, comme représenté schématiquement dans la figure 3. En même temps, les organes de commande 11 se déplacent dans les glissières 5.When it is desired to move the curtain 1 towards its closed position from its open position, the shaft 2 is driven by an electric motor 13. The roller 15, formed by the turns 14 of the curtain 1, and the wheels 7, which are fixed on the shaft 2, are therefore subjected to the same rotational movement. The curtain 1, which is held by its lateral edges 4 in the slides 5, is braked and in some cases even blocked in its movement towards its closed position due to the friction that necessarily exists between these edges 4 and the slides 5 From this follows that, when starting the closing of the curtain, the turns 14 of the roll gradually enlarge and detach from each other forming slack, as shown schematically in the figure 3 . At the same time, the control members 11 move in the slides 5.

Etant donné que, comme mentionné ci-dessus, le déplacement du rideau 1 est gêné par la présence dudit frottement entre les glissières 5 et les bords latéraux 4 du rideau 1, l'extrémité 16 des organes de commande 11 s'approche graduellement du bord inférieur 8 du rideau 1. Au moment où cette extrémité inférieure 16 est à la hauteur du bord inférieur 8 du rideau, cette extrémité 16 prend appui sur un ergot 17 qui est prévu à ce bord inférieur 8, comme représenté à la figure 3.Since, as mentioned above, the movement of the curtain 1 is hindered by the presence of said friction between the slides 5 and the lateral edges 4 of the curtain 1, the end 16 of the control members 11 gradually approaches the edge lower 8 of the curtain 1. At the moment when this lower end 16 is at the height of the lower edge 8 of the curtain, this end 16 is supported on a lug 17 which is provided at this lower edge 8, as shown in FIG. figure 3 .

A partir de ce moment, les organes de commande 11, entraînés par les roues d'entraînement 7, exercent une force de poussée sur le bord inférieur 8 du rideau 1, de sorte que les bords latéraux 4 du rideau 1 se déplacent dans les glissières 5 suivant leur direction longitudinale à la même vitesse que l'organe de commande 11.From this moment, the control members 11, driven by the drive wheels 7, exert a thrust force on the lower edge 8 of the curtain 1, so that the lateral edges 4 of the curtain 1 move in the slides 5 along their longitudinal direction at the same speed as the control member 11.

Dès que le diamètre du rouleau 15, formé par la partie enroulée du rideau 1, est devenu inférieur au diamètre primitif do de la roue d'entraînement 7, la vitesse de déplacement des organes de commande 11 devient plus grande que la vitesse de déplacement circonférentiel du rouleau 15. Ainsi, le mou formé disparaît au fur et à mesure que le rideau s'approche de sa position de fermeture, comme représenté dans la figure 5.As soon as the diameter of the roll 15, formed by the wound portion of the curtain 1, has become smaller than the pitch diameter do of the drive wheel 7, the speed of movement of the control members 11 becomes larger than the circumferential movement speed. 15. Thus, the formed slack disappears as the curtain approaches its closed position, as shown in FIG. figure 5 .

Au moment où le rideau 1 est dans sa position de fermeture, il est pratiquement complètement déroulé de l'arbre 2. Toutefois, comme déjà mentionné ci-dessus, il est possible que la longueur du rideau 1 soit plus grande que la hauteur de la baie 3 pour pouvoir compenser, par exemple, des tolérances de réglage qui pourraient être présentes, de sorte que, dans ce cas, une petite partie du rideau pourrait rester enroulée sur l'arbre 2.At the moment when the curtain 1 is in its closed position, it is practically completely unrolled from the shaft 2. However, as already mentioned above, it is possible that the length of the curtain 1 is greater than the height of the curtain. 3 to compensate for, for example, adjustment tolerances that could be present, so that in this case a small part of the curtain could remain wound on the shaft 2.

Lors de la réouverture du rideau, l'arbre 2 est actionné par le moteur électrique 13 dans le sens opposé à celui pour la fermeture du rideau 1. Ainsi, les spires 14 du rideau 1, qui sont éventuellement restées sur l'arbre 2, sont, dans un premier temps, tendues autour de ce dernier et ensuite le restant du rideau 1 est enroulé normalement autour de l'arbre 2.When reopening the curtain, the shaft 2 is actuated by the electric motor 13 in the opposite direction to that for closing the curtain 1. Thus, the turns 14 of the curtain 1, which may have remained on the shaft 2, are initially stretched around the latter and then the remainder of the curtain 1 is normally wound around the shaft 2.

Simultanément, les organes de commande 11, qui sont montés librement par rapport au rideau 1, sont déplacés dans les glissières 5 par l'action des roues d'entraînement 7. Etant donné qu'au départ le diamètre primitif d0 de ces roues d'entraînement 7 est supérieur au diamètre de la partie enroulée du rideau 1, l'extrémité inférieure 16 de l'organe de commande 11 s'éloigne graduellement du bord inférieur 8 du rideau 1. Ensuite, lorsque le diamètre de la partie enroulée du rideau 1 devient supérieur au diamètre primitif des roues d'entraînement 7 l'effet inverse se produit, et le rideau 1 subit un déplacement à une vitesse supérieure par rapport à celle des organes de commande 11.Simultaneously, the control members 11, which are mounted freely relative to the curtain 1, are moved in the slides 5 by the action of the drive wheels 7. Since initially the original diameter d 0 of these wheels d 7 is greater than the diameter of the wound portion of the curtain 1, the lower end 16 of the control member 11 moves away gradually from the lower edge 8 of the curtain 1. Then, when the diameter of the curled portion of the curtain 1 becomes greater than the pitch diameter of the drive wheels 7 the opposite effect occurs, and the curtain 1 is displaced at a higher speed than that of the control members 11.

Au moment où le rideau 1 est dans sa position d'ouverture, comme représenté dans les figures 1 et 2, la distance entre l'extrémité inférieure 16 des organes de commande 11 et le bord inférieur 8 du rideau 1 est de nouveau sensiblement égale à la distance X ou zéro.At the moment when the curtain 1 is in its open position, as shown in figures 1 and 2 , the distance between the lower end 16 of the control members 11 and the lower edge 8 of the curtain 1 is again substantially equal to the distance X or zero.

La partie de l'organe de commande 11 qui, dans la position d'ouverture, est située au-delà des roues d'entraînement 7 par rapport à son extrémité inférieure 16 peut être collectée dans une enceinte non représentée aux figures.The portion of the control member 11 which, in the open position, is located beyond the drive wheels 7 with respect to its lower end 16 may be collected in a chamber not shown in the figures.

Une section des glissières 5 est montrée schématiquement dans la figure 6. Ces glissières 5 comprennent deux canaux parallèles 18 et 19 qui s'étendent sur toute la longueur celles-ci.A section of the slides 5 is schematically shown in the figure 6 . These slides 5 comprise two parallel channels 18 and 19 which extend over the entire length thereof.

Dans un premier canal 18, qui présente une fente 20 dirigée vers la baie 3, est logé le bord latéral 4 du rideau 1. La partie de ce dernier adjacente à ce bord latéral 4 s'étend à travers la fente 20. Ainsi, le rideau 1 peut être déplacé suivant la direction longitudinale des glissières pendant que chacun des bords latéraux 4 est guidé dans ledit premier canal 18.In a first channel 18, which has a slot 20 directed towards the bay 3, is housed the lateral edge 4 of the curtain 1. The part of the latter adjacent to this side edge 4 extends through the slot 20. Thus, the curtain 1 can be moved in the longitudinal direction of the slides while each of the lateral edges 4 is guided in said first channel 18.

Le deuxième canal 19 sert comme chemin de guidage de l'organe de commande 11 le long du bord latéral 4 du rideau.The second channel 19 serves as a guide path of the control member 11 along the lateral edge 4 of the curtain.

Afin que l'extrémité inférieure 16 de cet organe de commande 11 puisse s'appuyer sur l'ergot 17 du bord inférieur 8 du rideau 1, un passage 21 est prévu entre lesdits canaux 18 et 19 s'étendant sur sensiblement toute la longueur de ces derniers pour permettre à l'ergot 17 de pénétrer dans le deuxième canal 19 et de coopérer ainsi avec l'organe de commande 11.So that the lower end 16 of this control member 11 can rest on the lug 17 of the lower edge 8 of the curtain 1, a passage 21 is provided between said channels 18 and 19 extending over substantially the entire length of these to allow the lug 17 to enter the second channel 19 and thus cooperate with the control member 11.

Le fait que l'ergot 17 s'étend à travers ledit passage 21 jusque dans le canal 19 a comme résultat qu'une partie de cet ergot est située en dessous de l'extrémité inférieure 16 de l'organe de commande 11.The fact that the lug 17 extends through said passage 21 into the channel 19 results in a part of this lug being situated below the lower end 16 of the control member 11.

Les dimensions dudit deuxième canal 19 correspondent sensiblement aux dimensions de l'organe de commande 11, de sorte que ce dernier ne peut pas se courber ou plier dans ce canal 19. De cette façon, l'organe de commande 11, qui est sensiblement incompressible dans sa direction longitudinale peut exercer une force de poussée sur l'ergot 17 prévu au bord inférieur 8 du rideau 1 par l'intermédiaire de la roue d'entraînement 7 et entraîner ainsi le rideau 1 vers sa position de fermeture.The dimensions of said second channel 19 correspond substantially to the dimensions of the control member 11, so that the latter can not bend or bend in this channel 19. In this way, the control member 11, which is substantially incompressible in its longitudinal direction may exert a thrust force on the lug 17 provided at the lower edge 8 of the curtain 1 through the drive wheel 7 and thus cause the curtain 1 to its closed position.

La partie des glissières 5 délimitant le canal 19 est, avantageusement, prolongé jusqu'au delà du niveau de l'axe 6 de l'arbre 2, en regard de la roue d'entraînement 7 de manière à pouvoir guider au maximum l'organe de commande 11. Ce prolongement a été désigné par la référence 5' dans les figures.The portion of the slides 5 delimiting the channel 19 is advantageously extended beyond the level of the axis 6 of the shaft 2, facing the drive wheel 7 so as to be able to guide the organ as far as possible. 11. This extension has been designated by the reference 5 'in the figures.

L'organe de commande 11 est, par exemple, constitué d'une bande ou lance en p-phenyleneterephtalamide, connu sous le nom commercial "Kevlar", pourvu d'un revêtement en tetrafluoroethylène, connu sous le nom commercial "Teflon", avec une épaisseur de 2 mm et une largeur de 20 mm. Cette bande présente une succession d'évidements 10 qui coopèrent avec les dents 9 prévues sur la roue d'entraînement 7, comme déjà décrit ci-dessus.The control member 11 is, for example, constituted by a strip or lance made of p- phenyleneterephthalamide, known under the trade name "Kevlar", provided with a tetrafluoroethylene coating, known under the trade name "Teflon", with a thickness of 2 mm and a width of 20 mm. This band has a succession of recesses 10 which cooperate with the teeth 9 provided on the drive wheel 7, as already described above.

Dans la forme de réalisation du dispositif, suivant l'invention, représentée dans les figures 1 à 6, la bande, qui forme l'organe de commande 11, s'étend dans les glissières 5 sensiblement dans le même plan que le rideau 1, comme il résulte de la figure 6. La largeur du passage 21 qui aboutit au canal 19, dans lequel est logé l'organe de commande 11 est inférieure à l'épaisseur de ce dernier, de sorte que cet organe ne peut pas pénétrer dans ce passage 21.In the embodiment of the device, according to the invention, represented in the Figures 1 to 6 , the strip, which forms the control member 11, extends in the slides 5 substantially in the same plane as the curtain 1, as is apparent from the figure 6 . The width of the passage 21 which leads to the channel 19, in which the control member 11 is housed, is smaller than the thickness of the latter, so that this member can not enter this passage 21.

Etant donné que, dans la forme de réalisation suivant les figures 1 à 6, l'organe de commande 11 est formé d'une bande souple étroite et de section transversale rectangulaire, il est également possible de prévoir que le canal 19 de section rectangulaire s'étend avec son grand côté dans une direction perpendiculaire par rapport au plan du rideau 1. Dans un tel cas, l'organe de commande subit une torsion de 90° dans l'espace entre la roue d'entraînement 7 et la glissière 5. Ainsi, le passage 21 pourrait avoir une largeur qui est plus grande que l'épaisseur de l'organe de commande 11, mais qui est inférieure à la largeur de ce dernier, comme montré dans la figure 7.Since in the embodiment according to the Figures 1 to 6 , the control member 11 is formed of a narrow flexible band and rectangular cross section, it is also possible to provide that the channel 19 of rectangular section extends with its long side in a direction perpendicular to the plane of the curtain 1. In such a case, the control member undergoes a 90 ° twist in the space between the drive wheel 7 and the slide 5 Thus, the passage 21 could have a width which is larger than the thickness of the control member 11, but which is smaller than the width of the latter, as shown in FIG. figure 7 .

Dans les figures 8 à 13, une deuxième forme de réalisation du dispositif à rideau, suivant l'invention, a été représentée qui se distingue essentiellement par rapport à la première forme de réalisation décrite ci-dessus par le fait que l'organe de commande est formée par une chaîne 11 s'engrenant avec une roue dentée traditionnelle 7 et qu'un lestage 22 est prévu au bord inférieur 8 du rideau 1 opposé au bord de ce dernier qui est fixé à l'arbre 2. La chaîne 11 est formée par une succession de maillots articulés l'un à l'autre autour d'axes parallèles, comme c'est par exemple le cas d'une chaîne à vélo.In the Figures 8 to 13 a second embodiment of the curtain device according to the invention has been shown which differs essentially from the first embodiment described above by the fact that the control member is formed by a chain 11 meshing with a traditional toothed wheel 7 and a ballast 22 is provided at the lower edge 8 of the curtain 1 opposite the edge thereof which is fixed to the shaft 2. The chain 11 is formed by a succession of articulated jerseys one to the other around parallel axes, as is the case for example with a bicycle chain.

Le diamètre primitif d0 de la roue dentée est inférieur au diamètre d1 du rouleau 15, qui est formé lorsque le rideau 1 est dans sa position d'ouverture, et supérieur au diamètre d2 de la partie encore enroulée 15 du rideau 1 lorsque ce dernier est dans la position de fermeture.The pitch diameter d 0 of the toothed wheel is smaller than the diameter d 1 of the roll 15, which is formed when the curtain 1 is in its open position, and greater than the diameter d 2 of the still wound portion 15 of the curtain 1 when the latter is in the closed position.

Lors de la fermeture du rideau 1, par la rotation de l'arbre 2, à partir de la position d'ouverture, comme représenté dans la figure 8, le rideau 1 se déroule de cet arbre 2 sans que du mou soit formé par suite de l'action du poids du lestage 22.When closing the curtain 1, by the rotation of the shaft 2, from the open position, as shown in FIG. figure 8 , the curtain 1 is unrolled from this shaft 2 without slack being formed as a result of the action of the ballast weight 22.

La chaîne 11 se déplace également suite à l'action de la roue dentée 7 dans la glissière 5. La roue dentée 7 est fixée coaxialement sur l'arbre 2. Cette chaîne 11, qui n'est pas fermée sur elle-même, est débitée à partir d'un bac 25 qui est installé en dessous de l'arbre 2.The chain 11 also moves following the action of the toothed wheel 7 in the slide 5. The toothed wheel 7 is fixed coaxially on the shaft 2. This chain 11, which is not closed on itself, is delivered from a tank 25 which is installed below the shaft 2.

Comme mentionné ci-dessus, lorsque le rideau 1 se déplace vers sa position de fermeture, il n'y a normalement pas de formation de mou autour de l'arbre 2 suite à l'action de traction exercée par le lestage 22 sur le rideau 1.As mentioned above, when the curtain 1 moves towards its closed position, there is normally no formation of slack around the shaft 2 following the tensile action exerted by the ballast 22 on the curtain 1.

Toutefois, lorsque sous l'action du vent, qui pourrait exercer une force de poussée sur le plan du rideau 1 pendant la fermeture de ce dernier, les bords latéraux 4 du rideau 1 sont freinés dans les glissières 5, le déplacement du rideau 1 s'arrête ou est ralenti. A ce moment, du mou se forme autour de l'arbre 2 et l'extrémité inférieure 16 de la chaîne 11, qui continue à se déplacer dans la glissière 5, s'approche du bord inférieur 8 du rideau 1 et entraîne celui-ci. Ceci est bien entendu également le cas pour la première forme de réalisation décrite ci-dessus.However, when under the action of the wind, which could exert a thrust force on the plane of the curtain 1 during the closing of the latter, the lateral edges 4 of the curtain 1 are braked in the slides 5, the movement of the curtain 1 s stops or is slowed down. At that moment, slack is formed around the shaft 2 and the lower end 16 of the chain 11, which continues to move in the slideway 5, approaches the lower edge 8 of the curtain 1 and drives it . This is of course also the case for the first embodiment described above.

Un détail de la chaîne 11 et de l'ergot 17 au bord inférieur 8 du rideau 1 est représenté dans la figure 11. Cet ergot 17 fait partie d'une pièce 26 en forme de L dont un bras constitue l'ergot 17 et s'étend parallèlement au bord inférieur 8 du rideau 1 dans la glissière correspondante 5, l'autre bras 27 s'étendant parallèlement au bord latéral correspondant 4 du rideau 1. La pièce 26 est, en particulier, constituée de deux plaques métalliques symétriques 28 et 29 qui sont fixées de part et d'autre du plan du rideau 1, de sorte que ce dernier est serré entre ces deux plaques 28 et 29.A detail of the chain 11 and the lug 17 at the lower edge 8 of the curtain 1 is shown in FIG. figure 11 . This lug 17 is part of an L-shaped piece 26, one arm of which constitutes the lug 17 and extends parallel to the lower edge 8 of the curtain 1 in the corresponding slideway 5, the other arm 27 extending parallel to the corresponding side edge 4 of the curtain 1. The part 26 is, in particular, consisting of two symmetrical metal plates 28 and 29 which are fixed on either side of the plane of the curtain 1, so that the latter is clamped between these two plates 28 and 29.

La glissière 5 présente une section telle à guider la chaîne 11 suivant sa direction longitudinale sans qu'elle ne puisse se dégager latéralement par rapport à celle-ci. Le bord latéral 4 du rideau est maintenu dans la glissière 5 entre la baie 3 et l'endroit où est guidée la chaîne 11, exactement comme dans la première forme de réalisation.The slide 5 has a section such as to guide the chain 11 in its longitudinal direction without it being able to disengage laterally with respect thereto. The lateral edge 4 of the curtain is held in the slideway 5 between the bay 3 and the place where the chain 11 is guided, exactly as in the first embodiment.

Lorsqu'une force au-dessus d'une certaine valeur est exercée sur le rideau 1 transversalement au plan de ce dernier, par exemple, par l'action d'un véhicule qui se heurte contre le rideau 1, les bords latéraux 4 de ce dernier se dégagent des glissières 5. A cet effet, il est prévu que les bords latéraux 4 du rideau 1 ou les glissières 5 peuvent se déformer élastiquement. Etant donné que la chaîne 11 n'est pas fixée au rideau 1, l'ergot 17 se dégage sans problème de la chaîne 11.When a force above a certain value is exerted on the curtain 1 transversely to the plane of the latter, for example, by the action of a vehicle which collides against the curtain 1, the lateral edges 4 of this The last slides emerge 5. To this end, it is provided that the lateral edges 4 of the curtain 1 or the slides 5 can deform elastically. Since the chain 11 is not fixed to the curtain 1, the lug 17 is easily disengaged from the chain 11.

Dans la figure 14 est représentée une troisième forme de réalisation du dispositif à rideau, suivant l'invention, qui se distingue essentiellement des deux formes de réalisation précédentes par le fait que l'organe de commande est formé par une courroie 33 qui est fermée sur elle-même. Cette courroie 33 est guidée et entraînée par les roues d'entraînement 7 fixées sur l'arbre 2. Ces roues d'entraînement peuvent, dans ce cas, être formées par des poulies.In the figure 14 is shown a third embodiment of the curtain device according to the invention, which differs essentially from the two previous embodiments in that the control member is formed by a belt 33 which is closed on itself. This belt 33 is guided and driven by the drive wheels 7 fixed on the shaft 2. These drive wheels can, in this case, be formed by pulleys.

Dans la partie inférieure de la baie 3, cette courroie 33 coopère avec une roulette 34, qui est de préférence montée d'une manière élastique, par exemple au moyen de ressorts hélicoïdaux 40, par rapport au sol afin de la maintenir constamment dans un état tendu.In the lower part of the bay 3, this belt 33 cooperates with a wheel 34, which is preferably mounted in an elastic manner, for example by means of helical springs 40, with respect to the ground so as to keep it constantly in a state tense.

Un élément de contact 35, formé, par exemple, par une saillie ou crochet, est fixé sur la courroie 33 entre ce bord inférieur 8 et l'arbre 2.A contact element 35, formed for example by a projection or hook, is fixed on the belt 33 between this lower edge 8 and the shaft 2.

Lors du déroulement du rideau 1 par la rotation de l'arbre 2, les spires successives 14 du rouleau 15 s'agrandissent et forment du mou comme dans la première forme de réalisation. Simultanément, la courroie 33 est déplacée suite à l'action de la roue d'entraînement 7 et l'élément de contact 35 se rapproche du bord inférieur 8. Lorsque l'élément de contact 35 touche l'ergot 17 du bord inférieur 8, il exerce une force sur ce bord inférieur 8 afin de déplacer le rideau 1 vers sa position de fermeture. Au fur et à mesure que cet élément de contact 35 se déplace, les spires du rideau 1 se déroulent et le mou diminue. En fait, cet élément de contact 35 rempli la même fonction que l'extrémité libre 16 de l'organe de commande de la première et de la deuxième forme de réalisation.During the unwinding of the curtain 1 by the rotation of the shaft 2, the successive turns 14 of the roll 15 enlarge and form slack as in the first embodiment. Simultaneously, the belt 33 is moved following the action of the drive wheel 7 and the contact element 35 approaches the lower edge 8. When the contact element 35 touches the lug 17 of the lower edge 8, it exerts a force on the lower edge 8 to move the curtain 1 to its closed position. As this contact member 35 moves, the turns of the curtain 1 unfurl and the slack decreases. In fact, this contact element 35 fulfills the same function as the free end 16 of the control member of the first and second embodiments.

Lors de l'ouverture du rideau à partir de sa position de fermeture, l'arbre 2 tourne dans le sens opposé à celui de la fermeture, de sorte que le rideau est enroulé sans mou sur l'arbre 2. Etant donné que le diamètre de la roue d'entraînement 7 est à ce moment supérieur au diamètre de la partie enroulée du rideau 1, l'élément de contact 35 s'éloigne du bord inférieur 8 du rideau jusqu'à ce que ces diamètres sont sensiblement égaux. Pendant l'enroulement de la partie restante du rideau 1, son bord inférieur 8 s'approche graduellement jusqu'à une petite distance de l'élément de contact 35, au moment où le rideau se trouve dans la position d'ouverture.When opening the curtain from its closed position, the shaft 2 rotates in the opposite direction to that of the closure, so that the curtain is wound without slack on the shaft 2. Since the diameter of the drive wheel 7 is at this moment greater than the diameter of the wound portion of the curtain 1, the contact element 35 moves away from the lower edge 8 of the curtain until these diameters are substantially equal. During the winding of the remaining part of the curtain 1, its lower edge 8 approaches gradually to a small distance from the contact element 35, at the moment when the curtain is in the open position.

La figure 15 concerne une quatrième forme de réalisation qui se caractérise par rapport aux précédentes formes de réalisation par le fait que le rideau 1 est enroulé autour d'un tambour 36 qui est coaxial avec l'arbre 2 et qui est monté librement sur ce dernier. La face latérale de ce tambour 36, dirigée vers la roue d'entraînement 7, est pourvue d'une butée 37 qui coopère avec une butée 38 qui est présente sur le côté de la roue d'entraînement 7 en regard du tambour 36. Les deux butées 37 et 38 sont montées à la même distance de l'axe 6 de l'arbre 2.The figure 15 relates to a fourth embodiment which is characterized with respect to the previous embodiments in that the curtain 1 is wound around a drum 36 which is coaxial with the shaft 2 and which is freely mounted on the latter. The lateral face of this drum 36, directed towards the drive wheel 7, is provided with a stop 37 which cooperates with a stop 38 which is present on the side of the drive wheel 7 facing the drum 36. two stops 37 and 38 are mounted at the same distance from the axis 6 of the shaft 2.

Dans un premier temps, lors de la mise en rotation de l'arbre 2 et de la roue d'entraînement 7 pour déplacer le rideau 1 vers sa position de fermeture, les organes de commande, non représentés à la figure 15, se déplacent vers le bord du rideau 1 opposé à celui monté sur le tambour 36 pendant que ce dernier reste sensiblement immobile. Au moment où ces organes agissent sur ce bord, le rideau 1 se déroule à la même vitesse linéaire que l'organe de commande. Ceci a comme conséquence que le tambour 36 tourne à une vitesse angulaire inférieure à cette de la roue d'entraînement 7 étant donné que le diamètre de la partie enroulée du rideau est supérieur au diamètre de la roue d'entraînement 7.In a first step, during the rotation of the shaft 2 and the drive wheel 7 to move the curtain 1 towards its closed position, the control members, not shown in FIG. figure 15 , move towards the edge of the curtain 1 opposite to that mounted on the drum 36 while the latter remains substantially immobile. At the moment when these members act on this edge, the curtain 1 is at the same linear speed as the control member. As a result, the drum 36 rotates at a lower angular velocity than that of the drive wheel 7 since the diameter of the curled portion of the curtain is greater than the diameter of the drive wheel 7.

Dès que le diamètre de la partie enroulée du rideau 1 est devenu sensiblement égal au diamètre de la roue d'entraînement 7, le tambour tourne à la même vitesse angulaire que la roue d'entraînement. Au fur et à mesure que le diamètre de la partie enroulée du rideau 1 diminue par rapport au diamètre de la roue d'entraînement 7, la vitesse de rotation du tambour 36 augmente par rapport à celle de la roue d'entraînement 7 jusqu'à la position de fermeture du rideau. Le dispositif peut être dimensionné pour que la butée 37 vienne en contact avec la butée 38 au moment où le rideau atteint sa position de fermeture. Il est, toutefois, possible de prévoir que même dans la position de fermeture, ces butées 37 et 38 ne se touchent pas.As soon as the diameter of the wound portion of the curtain 1 has become substantially equal to the diameter of the drive wheel 7, the drum rotates at the same angular speed as the drive wheel. As the diameter of the curled portion of the curtain 1 decreases relative to the diameter of the drive wheel 7, the The rotational speed of the drum 36 increases relative to that of the drive wheel 7 to the closed position of the curtain. The device may be dimensioned so that the stop 37 comes into contact with the stop 38 at the moment when the curtain reaches its closed position. It is, however, possible to provide that even in the closed position, these stops 37 and 38 do not touch.

Dans cette forme de réalisation les dimensions du dispositif sont choisies d'une manière telle qu'aucun mou n'est formé dans le rideau 1 lors de la fermeture de ce dernier. Pendant cette fermeture, le tambour 36 tourne uniquement autour de son axe 6 par l'action de l'extrémité inférieure des organes de commande 11 sur les ergots prévus à cet effet au bord du rideau 1 opposé à celui du côté de l'arbre 2. Il n'y a pas de contact entre les butées 37 et 38 lors de ce déplacement vers la position de fermeture du rideau 1.In this embodiment the dimensions of the device are chosen in such a way that no slack is formed in the curtain 1 during the closure of the latter. During this closure, the drum 36 rotates only about its axis 6 by the action of the lower end of the control members 11 on the lugs provided for this purpose at the edge of the curtain 1 opposite that of the side of the shaft 2 There is no contact between the stops 37 and 38 during this movement towards the closed position of the curtain 1.

Lors de l'ouverture du rideau 1 à partir de sa position de fermeture par la rotation de l'arbre 2 dans le sens inversé par rapport à celui pendant la fermeture, la butée 38 de la roue d'entraînement 7 s'appui contre la butée 37 du tambour 36, de sorte que ce dernier est actionné par la roue d'entraînement 7 et que le rideau 1 est enroulé autour du tambour 36. Etant donné que lors du commencement de l'ouverture du rideau 1, le diamètre de la partie enroulée du rideau 1 est inférieur au diamètre de la roue d'entraînement 7, l'organe de commande 11 est remonté plus vite que le rideau 1.When opening the curtain 1 from its closed position by the rotation of the shaft 2 in the opposite direction to that during closing, the stop 38 of the drive wheel 7 bears against the stop 37 of the drum 36, so that the latter is actuated by the drive wheel 7 and the curtain 1 is wound around the drum 36. Since at the beginning of the opening of the curtain 1, the diameter of the wound part of the curtain 1 is smaller than the diameter of the drive wheel 7, the control member 11 is raised faster than the curtain 1.

In est clair que lorsque la baie à fermer par le rideau est d'une très grande hauteur, du mou pourrait se former lors de la fermeture du rideau lorsque les butées 37 et 38 se touchent pendant cette fermeture. Dans un tel cas, l'importance de ce mou est néanmoins réduite par rapport aux autres formes de réalisation décrites ci-dessus.It is clear that when the bay to be closed by the curtain is of a very great height, slack could be formed when closing the curtain when the stops 37 and 38 touch during this closure. In such a case, the importance of this slack is nevertheless reduced compared to the other embodiments described above.

L'ensemble du tambour 36 et des butées 37 et 38 forme un compensateur ayant pour but de diminuer ou d'éviter la formation de mou lors du déplacement du rideau. Ce compensateur est de construction très simple et ne nécessite, par exemple, pas la présence de ressorts.The assembly of the drum 36 and stops 37 and 38 forms a compensator whose purpose is to reduce or avoid the formation of slack when moving the curtain. This compensator is of very simple construction and does not require, for example, the presence of springs.

Dans une forme de réalisation du dispositif à rideau où un compensateur est prévu, il est également possible de fixer l'extrémité inférieure de l'organe de commande, ou l'élément de contact 35, à l'ergot 17 d'une manière amovible. Ainsi, le bord du rideau 1 opposé à celui orienté vers l'arbre 2 est relié aux organes de commande pendant tout le cycle de fermeture ou d'ouverture et ceci jusqu'à ce que les bords latéraux 4 du rideau 1 se dégagent des glissières, par exemple, par l'action d'un véhicule qui se heurte contre le rideau 1. Dans un tel cas, l'extrémité inférieure 16 de l'organe de commande, ou l'élément de contact 35, est séparé automatiquement de l'ergot 17.In one embodiment of the curtain device where a compensator is provided, it is also possible to fix the lower end of the control member, or the contact element 35, to the lug 17 in a removable manner. . Thus, the edge of the curtain 1 opposite the one facing the shaft 2 is connected to the control members during the entire closing or opening cycle and this until the lateral edges 4 of the curtain 1 emerge slides for example, by the action of a vehicle against the curtain 1. In such a case, the lower end 16 of the control member, or the contact element 35, is automatically separated from the lug 17.

De plus, l'extrémité libre 16 de la lance devant coopérer avec le rideau est de préférence biseautée comme d'ailleurs l'ergot 17, de manière à permettre de faciliter le dégagement du bord latéral 5 du rideau 1 des glissières sous l'action d'un obstacle, comme indiqué ci-dessus.In addition, the free end 16 of the lance to cooperate with the curtain is preferably beveled as also the lug 17, so as to facilitate the release of the side edge 5 of the curtain 1 of the slides under the action an obstacle, as indicated above.

Dans la deuxième forme de réalisation, on peut prévoir un embout biseauté à l'extrémité libre de la chaîne 11, de la même manière que l'extrémité de la lance.In the second embodiment, a beveled tip may be provided at the free end of the chain 11, in the same manner as the end of the lance.

La figure 16 est relative à une cinquième forme de réalisation qui se caractérise par rapport à la première forme de réalisation représentée notamment dans la figure 2, par le fait que l'extrémité de bande 11, qui forme l'organe de commande, est fixée par son extrémité opposée à celle devant agir sur le rideau 1 sur l'arbre 2 et que cette bande 11 est enroulée ou déroulée entre les spires 14 du rouleau 15 du rideau 1. Ceci permet d'éviter l'utilisation d'un bac, comme dans la deuxième forme de réalisation, pour loger la partie de l'organe de commande, formé par une lanière ou une lance, au delà de la roue d'entraînement.The figure 16 relates to a fifth embodiment which is characterized with respect to the first embodiment represented in particular in the figure 2 in that the band end 11, which forms the control member, is fixed by its end opposite to that to act on the curtain 1 on the shaft 2 and that this band 11 is wound or unwound between the turns 14 of the roll 15 of the curtain 1. This avoids the use of a tray, as in the second embodiment, to accommodate the portion of the control member, formed by a strap or a lance, to beyond the drive wheel.

Afin de pouvoir compenser la différence de diamètre entre la partie enroulée du rideau 1 et de la roue d'entraînement 7, l'on prévoit que la bande 11 ait une longueur suffisante pour permettre que la spire extérieure 12 de la partie enroulée de cette bande 11 forme une boucle de la même manière qu'un mou autour de l'arbre 2.In order to be able to compensate for the difference in diameter between the wound portion of the curtain 1 and the drive wheel 7, it is expected that the band 11 has a length sufficient to allow the outer turn 12 of the wound portion of this band 11 forms a loop in the same way as a slack around the tree 2.

La figure 17 concerne une forme de réalisation qui se distingue des formes de réalisation précédentes par le fait que l'organe de commande formée par une lanière incompressible 11, est enroulée d'une manière hélicoïdale sur une roue d'entraînement tronconique 7 dentée ou non, dont la forme est telle à ce que, aussi bien lors du déroulement que lors de l'enroulement, la vitesse de déplacement linéaire de la lanière corresponde à celle du rideau 1 entre sa position d'ouverture et sa position de fermeture.The figure 17 relates to an embodiment which differs from the preceding embodiments in that the control member formed by an incompressible strap 11, is wound helically on a frustoconical drive wheel 7 toothed or not, whose shape is such that, both during unwinding and during winding, the linear speed of movement of the strap corresponds to that of the curtain 1 between its open position and its closed position.

Lorsque cette roue 7 n'est pas dentée, on prévoit de préférence dans la surface extérieure de celle-ci des rainures, non représentées, qui s'étendent hélicoïdalement autour de l'axe 6 et dans lesquelles se déplace l'organe de commande 11. Un boîtier 47 est prévu autours de la roue d'entraînement 7 qui présente dans sa partie inférieure une fente 48 qui s'étend dans un plan passant par l'axe 6 de l'arbre 2 et parallèle à la direction de déplacement du rideau 1 entre sa position d'ouverture et sa position de fermeture à travers de laquelle l'organe de commande 11 peut être enroulé sur ou se dérouler de la roue d'entraînement 7.When this wheel 7 is not toothed, it is preferably provided in the outer surface thereof grooves, not shown, which extend helically around the axis 6 and in which the control member 11 moves A housing 47 is provided around the drive wheel 7 which has in its lower part a slot 48 which extends in a plane passing through the axis 6 of the shaft 2 and parallel to the direction of movement of the curtain 1 between its open position and its closed position through which the control member 11 can be wound on or unwind from the drive wheel 7.

Dans d'autres cas, par exemple pour le recouvrement de piscine, de vérandas, etc., si, au contraire, il y a lieu d'éviter que les bords latéraux du rideau sortent des glissières, celles-ci sont réalisées en une matière rigide ou sont rendues rigides. Par ailleurs, les ergots sont fixés au bord du rideau opposé à celui du côté de l'arbre sur lequel le rideau est monté et sont maintenus à coulissement dans les glissières. Ceci n'est donc possible que pour les formes de réalisation où l'organe de commande est constamment en contact avec l'ergot lors du déplacement du rideau.In other cases, for example for the pool cover, verandas, etc., if, on the contrary, it is necessary to prevent the lateral edges of the curtain from coming out of the slides, these are made of a material rigid or are made rigid. Furthermore, the lugs are attached to the edge of the curtain opposite to that of the side of the shaft on which the curtain is mounted and are held slidably in the slideways. This is therefore only possible for the embodiments where the control member is constantly in contact with the lug when moving the curtain.

Les figures 18 à 20 montrent une forme de réalisation dans laquelle le rideau se déplace horizontalement entre une position d'ouverture et une position de fermeture. Le bord 8 du rideau 1 opposé à celui du côté de l'arbre 2 est formé par une barre rigide dont les extrémités forment les ergots qui s'engagent à coulissement dans les glissières 5, de sorte que les ergots ne peuvent pas se dégager de ces dernières.The Figures 18 to 20 show an embodiment in which the curtain moves horizontally between an open position and a closed position. The edge 8 of the curtain 1 opposite the one on the side of the shaft 2 is formed by a rigid bar whose ends form the lugs which engage in sliding in the slides 5, so that the lugs can not disengage from these last.

Pour permettre de tendre le rideau 1 dans sa position de fermeture, une surépaisseur 41, de préférence rigide, s'étend sur toute la largeur de la face extérieure du rideau 1, parallèlement à l'axe de l'arbre 2 et prend appui dans la position de fermeture du rideau 1 contre une barre transversale rigide 42 s'étendant également parallèlement à l'axe de l'arbre 2. Cette barre 42 est montée sur les parties fixes du dispositif, comme les glissières 5.To make it possible to tension the curtain 1 in its closed position, an extra thickness 41, preferably rigid, extends over the entire width of the outer face of the curtain 1, parallel to the axis of the shaft 2 and bears in the closing position of the curtain 1 against a rigid transverse bar 42 also extending parallel to the axis of the shaft 2. This bar 42 is mounted on the fixed parts of the device, such as the slides 5.

Il faut donc que la distance parcourue par le rideau à partir de la barre 42 jusqu'à dans sa position de fermeture corresponde à la distance entre la surépaisseur 41 et le bord 8 du rideau 1. A cet égard, aussi bien la position de la barre 42 que celle de la surépaisseur 41 pourrait être réglable.It is therefore necessary that the distance traveled by the curtain from the bar 42 to its closed position corresponds to the distance between the extra thickness 41 and the edge 8 of the curtain 1. In this respect, both the position of the bar 42 than that of the extra thickness 41 could be adjustable.

Ceci permet que du mou, qui serait éventuellement présent, reste dans la partie du rideau 1 en amont de cette surépaisseur 41. Cette solution est surtout importante pour les dispositifs ne comprenant pas de glissières pour les bords latéraux du rideau 1 ou pour lesquels il n'est pas possible de prévoir un lestage au bord inférieur du rideau opposé à celui du côté de l'arbre 2. Ceci est par exemple le cas lorsque le rideau, dont les bords latéraux ne sont pas guidés, se déplace horizontalement, comme dans les figures 18 à 20.This allows slack, which would possibly be present, to remain in the part of the curtain 1 upstream of this excess thickness 41. This solution is especially important for devices that do not include slides for the lateral edges of the curtain 1 or for which it It is not possible to provide a ballast at the lower edge of the curtain opposite to that of the side of the shaft 2. This is for example the case when the curtain, whose lateral edges are not guided, moves horizontally, as in the Figures 18 to 20 .

La figure 21 concerne une particularité pouvant être adaptée sur pratiquement toutes les formes de réalisation décrites ci-dessus, mais qui est surtout utile pour des rideaux relativement longs et/ou qui se déplacent avec un frottement relativement important dans des glissières. Ceci pourrait être le cas dans la forme de réalisation montrée aux figures 18 à 20.The figure 21 relates to a feature that can be adapted to virtually all the embodiments described above, but which is especially useful for relatively long curtains and / or which move with a relatively high friction in slides. This could be the case in the embodiment shown in FIGS. Figures 18 to 20 .

Cette particularité consiste à prévoir dans les glissières 5, par exemple à proximité de la roue d'entraînement, entre la position d'ouverture et de fermeture du rideau, une ouverture 43 dans laquelle l'organe de commande 11 peut pénétrer lors de son déplacement dans la glissière 5 au moment où une obstruction se produit dans la glissière en aval de cette ouverture 43 en considérant le sens de déplacement de l'organe de commande 11.This feature consists in providing in the slides 5, for example near the drive wheel, between the opening and closing position of the curtain, an opening 43 in which the control member 11 can penetrate during its displacement. in the slideway 5 at the moment when an obstruction occurs in the slideway downstream of this opening 43 by considering the direction of movement of the control member 11.

Dans un tel cas, la partie 11' de l'organe de commande 11 traversant cette ouverture 43 agit sur un détecteur 44 qui envoie alors un signal à un poste de contrôle non représenté. Ce poste de contrôle pourrait éventuellement mettre un mécanisme en action pour remédier au problème ainsi créé.In such a case, the portion 11 'of the control member 11 passing through this opening 43 acts on a detector 44 which then sends a signal to a control station not shown. This checkpoint could possibly put a mechanism in action to remedy the problem thus created.

Dans les formes de réalisation précédentes, l'organe de commande et les bords latéraux du rideau se déplacent dans une même glissière. Il est, toutefois possible de prévoir une glissière, ou d'autres moyens séparés, pour guider l'organe de commande qui est entièrement indépendante des glissières pour les bords latéraux du rideau et qui permet, par exemple, de déplacer l'organe de commande sur un parcours rectiligne à partir de la roue d'entraînement ou vers cette dernière.In the previous embodiments, the control member and the lateral edges of the curtain move in the same slide. It is possible, however, to provide a slide, or other separate means, to guide the control member which is completely independent of the slides for the lateral edges of the curtain and which allows, for example, to move the control member on a straight path from or to the drive wheel.

Dans les dispositifs à rideau, suivant l'invention, décrits ci-dessus, une roue d'entraînement 7 qui est fixée sur l'arbre 2, est prévue de chaque côté du rideau. Ainsi, le mouvement des organes de commande correspondants est entièrement synchronisé.In the curtain devices according to the invention described above, a drive wheel 7 which is fixed on the shaft 2 is provided on each side of the curtain. Thus, the movement of the corresponding control members is fully synchronized.

Le rideau 1 est, de préférence, constitué d'un matériau qui permet que les spires successives du rideau enroulé glissent les unes par rapport aux autres, de sorte que le rideau est, par exemple, constitué d'un matériau lisse et continu, comme par exemple une bâche en une matière plastique, éventuellement polie.The curtain 1 is preferably made of a material which allows the successive turns of the rolled curtain to slide relative to each other, so that the curtain is, for example, made of a smooth and continuous material, such as for example a tarpaulin made of a plastic material, possibly polished.

Lorsque l'organe de commande est formé par une lance ou un lanière incompressible qui n'est pas fermée sur elle-même, comme dans les formes de réalisation décrites ci-dessus, exceptée la troisième forme de réalisation, cet organe de commande n'agit que sur le rideau pour le déplacer vers sa position de fermeture, l'ouverture étant réalisée par la rotation de l'arbre 2 autour de son axe 6 dans le sens opposé à celui lors de la fermeture.When the control member is formed by a lance or an incompressible lanyard which is not closed on itself, as in the embodiments described above, except the third embodiment, this control member n ' It acts only on the curtain to move it towards its closed position, the opening being achieved by the rotation of the shaft 2 about its axis 6 in the opposite direction to that during the closing.

Il est également à conseiller de choisir la longueur du rideau quelque peu plus élevée que la hauteur de la baie, de sorte qu'également dans la position de fermeture un léger mou est présent autour de l'arbre 2. Ceci permet de compenser des variations dans les dimensions du dispositif et de la baie, ainsi que de tenir compte de variations de température qui pourraient avoir un effet sur la longueur du rideau.It is also advisable to choose the length of the curtain somewhat higher than the height of the bay, so that also in the closed position a slight softness is present around the shaft 2. This makes it possible to compensate for variations in the dimensions of the device and the bay, as well as to take into account temperature variations that could have an effect on the length of the curtain.

Enfin, dans certains cas, l'ergot prévu au bord du rideau opposé à celui du côté de l'arbre peut être escamotable, par exemple au moyen d'un levier, pour permettre une installation et un montage plus aisé du dispositif et aussi une réintroduction plus facile de cet ergot dans les glissières suite à un dégagement du rideau de ces dernières, surtout lorsque le bord du rideau opposé à celui du côté de l'arbre 2 présente une barre rigide, comme dans la septième forme de réalisation.Finally, in some cases, the lug provided at the edge of the curtain opposite the side of the shaft can be retractable, for example by means of a lever, to allow easier installation and assembly of the device and also a easier reintroduction of this lug in the slides following a clearance of the curtain thereof, especially when the edge of the curtain opposite that of the side of the shaft 2 has a rigid bar, as in the seventh embodiment.

Quoique les dispositifs à rideau décrits ci-dessus soient pourvus de glissières, il est clair que la présence de ces glissières n'est pas essentielle pour l'invention.Although the curtain devices described above are provided with slides, it is clear that the presence of these slides is not essential for the invention.

Il est bien entendu que l'invention n'est pas limitée aux différentes formes de réalisation décrites ci-dessus, mais que d'autres variantes encore peuvent être envisagées sans sortir du cadre de la présente invention.It is understood that the invention is not limited to the various embodiments described above, but that other variants may be considered without departing from the scope of the present invention.

Pour des dispositifs de dimensions réduites, le rideau et les roues d'entraînement pourraient être actionnés manuellement, par exemple, au moyen d'un levier monté sur l'arbre d'enroulement du rideau.For devices of reduced dimensions, the curtain and the drive wheels could be operated manually, for example by means of a lever mounted on the winding shaft of the curtain.

Dans certains cas, si le rideau est réalisé en une matière suffisamment lourde, le lestage peut être omis.In some cases, if the curtain is made of a sufficiently heavy material, the ballasting may be omitted.

Dans la septième forme de réalisation, la barre rigide du bord 8 peut être remplacée par deux plots à chacune des extrémités de ce bord qui s'engagent dans les glissières.In the seventh embodiment, the rigid bar of the edge 8 can be replaced by two studs at each end of this edge which engage in the slideways.

Par ailleurs, dans chacun des formes de réalisation décrites ci-dessus, des moyens sont avantageusement prévus permettant d'enrouler au maximum une spire de l'organe de commande autour de la roue d'entraînement parallèlement à un plan perpendiculaire à l'axe de l'arbre 2, de sorte que le diamètre primitif de la roue d'entraînement reste sensiblement constant. De cette façon, l'organe de commande se déplacera toujours à la même vitesse lors de la fermeture et l'ouverture du rideau. Les moyens précités sont ceux qui permettent d'éviter l'enroulement de l'organe de commande sur lui-même autour de la roue d'entraînement.Furthermore, in each of the embodiments described above, means are advantageously provided for winding a maximum of one turn of the control member around the drive wheel parallel to a plane perpendicular to the axis of the shaft 2, so that the pitch diameter of the drive wheel remains substantially constant. In this way, the control member will always move at the same speed when closing and opening the curtain. The aforementioned means are those that prevent the winding of the control member on itself around the drive wheel.
