Description

La présente invention concerne le domaine technique des volets roulants à lames destinés à assurer l'occultation d'une baie au sens général mais elle vise plus précisément les volets roulants comportant des lames à caractère orientable.The present invention relates to the technical field of shutters with blades intended to ensure the concealment of a bay in the general sense but more specifically the shutters with blades of adjustable character.

D'une manière générale, un volet roulant comporte une série de lames ou de lattes horizontales articulées entre elles pour former un rideau d'occultation guidé en coulissement dans des glissières verticales. Ce rideau est entraîné par un tambour d'entraînement, en coulissement vertical descendant jusqu'à une butée basse pour occuper une position d'occultation complète et en coulissement vertical ascendant pour occuper une position d'ouverture partielle ou complète dans laquelle les lames sont enroulées autour du tambour.In general, a roller shutter comprises a series of blades or horizontal slats hinged together to form a concealment curtain slidably guided in vertical rails. This curtain is driven by a drive drum, vertically sliding down to a low stop to occupy a complete occlusion position and vertical sliding upwards to occupy a partial or complete opening position in which the blades are wound around the drum.

La fonction première de ce volet roulant est d'obturer une baie afin de protéger de la lumière extérieure et contre les effractions. Cependant, il est apparu le besoin supplémentaire d'aérer les pièces occultées. A cet effet, l'art antérieur a proposé de réaliser des fentes dans les lames permettant une aération et une modulation de la lumière entrante. Cette solution ne donne pas satisfaction en pratique car elle ne permet pas une aération suffisante.The primary function of this shutter is to close a bay to protect from outside light and against break-ins. However, it appeared the additional need to ventilate the occulted rooms. For this purpose, the prior art has proposed making slots in the blades allowing ventilation and modulation of the incoming light. This solution is unsatisfactory in practice because it does not allow sufficient ventilation.

Pour assurer cette double fonction de protection et d'aération, le brevet européen 2 398 993 propose de réaliser un rideau comportant des lames orientables comportant chacune un support et une aile orientable montée pivotante sur la partie supérieure du support selon un premier pivot et sur la partie inférieure de la lame supérieure successive selon un deuxième pivot de sorte que l'aile est apte à occuper une position ajourée ou une position fermée. En l'absence d'efforts sur ces lames, les lames orientables occupent la position fermée en raison de la gravité.To ensure this dual function of protection and ventilation, the European patent 2,398,993 proposes to make a curtain comprising steerable blades each comprising a support and an orientable wing pivotally mounted on the upper part of the support according to a first pivot and on the lower part of the successive upper blade according to a second pivot so that the wing is able to occupy a perforated position or a closed position. In the absence of efforts on these blades, the directional blades occupy the closed position due to gravity.

Ainsi, lorsque le tambour d'entraînement est commandé en rotation par une commande agissant pour assurer le coulissement descendant du rideau pour l'amener jusqu'à une butée basse, les ailes orientables des lames sont en position fermée. Lorsque ce coulissement descendant est poursuivi après la mise en butée de la lame inférieure, les ailes orientables des lames, à partir de la lame la plus basse, viennent successivement occuper leur position ajourée. Il est ainsi possible de placer à volonté les ailes en position ajourée à partir du bas du rideau jusqu'à une hauteur choisie en fonction du degré de coulissement réalisé. Si cette solution permet d'obtenir une aération convenable et une modulation de la lumière entrante, cette solution nécessite le recours à une lame inférieure de hauteur réglable pour s'ajuster aux tolérances de montage tout en assurant la fonction de butée pour l'ouverture des ailes des lames. Par ailleurs, la fonction de sécurité anti effraction n'est plus assurée par un tel rideau. Enfin, l'ouverture obligatoire des ailes à partir des lames inférieures entraîne un risque d'entrée des animaux rampants.Thus, when the drive drum is rotated by a control acting to ensure the sliding down of the curtain to bring it to a low stop, the swivel wings of the blades are in the closed position. When this downward sliding is continued after the abutment of the lower blade, the swiveling wings of the blades, from the lowest blade, successively take their place. openwork position. It is thus possible to place the wings at will open position from the bottom of the curtain to a height chosen according to the degree of sliding achieved. If this solution provides adequate ventilation and modulation of the incoming light, this solution requires the use of a lower blade of adjustable height to adjust to the mounting tolerances while providing the stop function for the opening of the lights. wings of the blades. Moreover, the function of burglar-proof security is no longer provided by such a curtain. Finally, the mandatory opening of the wings from the lower blades entails a risk of entry of crawling animals.

La présente invention vise à remédier aux inconvénients de l'art antérieur en proposant un nouveau volet roulant à lames orientables présentant une conception simple et apte à assurer une protection efficace tout en permettant une aération efficace et une modulation à volonté de la lumière entrante.The present invention aims to overcome the drawbacks of the prior art by proposing a new rolling shutter with adjustable blades having a simple design and capable of providing effective protection while allowing effective ventilation and modulation at will of the incoming light.

Pour atteindre de tels objectifs, le volet roulant conforme à l'invention comporte une série de lames superposées articulées entre elles pour former un rideau d'occultation guidé en coulissement dans des glissières verticales et entraîné par un tambour d'entraînement, en coulissement vertical descendant jusqu'à une butée basse pour occuper une position d'occultation complète et en coulissement vertical ascendant pour occuper une position d'ouverture, ce rideau comportant au moins une lame orientable comportant un support et une aile orientable montée pivotante sur la partie supérieure du support selon un premier pivot et sur la partie inférieure de la lame supérieure successive selon un deuxième pivot de sorte que l'aile est apte à occuper une position ajourée ou une position fermée. Selon l'invention, le premier pivot et le deuxième pivot sont agencés de manière que d'une part, en l'absence d'un effort exercé par la lame supérieure sur l'aile, l'effet du poids du rideau exercé sur la partie inférieure du support, amène le premier pivot et le deuxième pivot à occuper une position sensiblement superposée de sorte que l'aile occupe sa position ajourée, et que d'autre part, l'application d'un effort de poussée par la lame supérieure sur l'aile entraîne un décalage latéral entre le premier pivot et le deuxième pivot de sorte que cette aile occupe sa position fermée.To achieve such objectives, the shutter according to the invention comprises a series of superimposed blades hinged together to form a concealment curtain slidably guided in vertical slides and driven by a drive drum, in downward vertical sliding up to a low stop to occupy a complete occlusion position and vertical sliding upwards to occupy an open position, this curtain comprising at least one orientable blade having a support and an orientable wing pivotally mounted on the upper part of the support in a first pivot and on the lower part of the successive upper blade according to a second pivot so that the wing is adapted to occupy a perforated position or a closed position. According to the invention, the first pivot and the second pivot are arranged so that on the one hand, in the absence of a force exerted by the upper blade on the wing, the effect of the weight of the curtain exerted on the lower part of the support, causes the first pivot and the second pivot to occupy a substantially superimposed position so that the wing occupies its open position, and secondly, the application of a thrust force by the upper blade on the wing drives a lateral offset between the first pivot and the second pivot so that the wing occupies its closed position.

L'objet de l'invention concerne un volet roulant 1 comportant une série de lames horizontales 2f, 2o articulées entre elles pour former un rideau d'occultation 3 guidé en coulissement dans des glissières verticales 4 représentées uniquement à titre d'illustration par des traits discontinus. Ce rideau d'occultation 3 est entraîné par un tambour d'entraînement 5 représenté également uniquement à titre d'illustration par son axe de rotation. Ce tambour 5 entraîne le rideau 3 en coulissement vertical descendant jusqu'à une butée basse B pour occuper une position d'occultation complète et en coulissement vertical ascendant pour occuper une position d'ouverture. Ce tambour 5 est entraîné en rotation à l'aide d'une commande manuelle ou motorisée pour assurer le coulissement ascendant et descendant du rideau d'occultation 3. Le tambour 5 et les glissières 4 ne sont pas décrits plus précisément car ils sont bien connus de l'homme du métier.The object of the invention relates to a shutter 1 comprising a series of horizontal blades 2f, 2o hinged together to form a concealment curtain 3 slidably guided in vertical rails 4 shown only for illustration by lines discontinuous. This occulting curtain 3 is driven by a drive drum 5 also shown only for illustration by its axis of rotation. This drum 5 drives the curtain 3 vertically sliding down to a low stop B to occupy a complete occlusion position and vertical sliding ascending to occupy an open position. This drum 5 is rotated by means of a manual or motorized control to ensure the upward and downward sliding of the occulting curtain 3. The drum 5 and the slides 4 are not described more precisely because they are well known of the skilled person.

Ce rideau d'occultation 3 comporte au moins une lame orientable 2o et dans l'exemple illustré aux Fig. 1 et 2 , une série de lames orientables 2o consécutives et des lames fixes 2f. Chaque lame orientable 2o comporte au moins une fenêtre 8 d'aération et de passage de la lumière. Bien entendu, les lames orientables 2o peuvent être réparties le long du rideau de toute manière appropriée et leur nombre est choisi à volonté en fonction du niveau de modulation souhaité pour l'air et la lumière. Typiquement, le rideau 3 peut comporter une seule série de lames orientables 2o consécutives ou plusieurs séries consécutives de lames orientables 2o, ces séries de lames orientables consécutives étant séparées par une ou plusieurs lames fixes 2f. This occulting curtain 3 comprises at least one orientable blade 2o and in the example illustrated in FIGS. Fig. 1 and 2 , a series of consecutive 2o swivel blades and fixed blades 2f. Each steerable blade 2o has at least one window 8 aeration and passage of light. Of course, the steerable blades 2o can be distributed along the curtain in any appropriate manner and their number is chosen at will according to the desired level of modulation for air and light. Typically, the curtain 3 may comprise a single series of consecutive steerable blades 2o or several consecutive series of steerable blades 2o, these series of consecutive steerable blades being separated by one or more fixed blades 2f.

Tel que cela ressort plus précisément des Fig. 3 , 6 et 7 , chaque lame orientable 2o comporte un support 9 et une aile orientable 10 montée pivotante sur la partie supérieure du support 9 selon un premier pivot 11 et sur la partie inférieure 12 de la lame supérieure successive selon un deuxième pivot 13. Chaque aile orientable 10 est donc apte à occuper une position ajourée pour laquelle la fenêtre 8 est ouverte ( Fig. 6 ) ou une position fermée pour laquelle la fenêtre 8 est obturée ( Fig. 7 ). Ce premier pivot 11 et ce deuxième pivot 13 sont écartés l'un de l'autre d'une mesure déterminée. Au cours du coulissement du rideau, la position relative entre ces pivots 11, 13 change à la manière d'un levier agissant pour assurer la rotation de l'aile orientable 10. As more specifically Fig. 3 , 6 and 7 Each adjustable blade 2o comprises a support 9 and a swiveling wing 10 pivotally mounted on the upper support 9 according to a first pivot 11 and on the lower part 12 of the next upper blade according to a second pivot 13. Each wing 10 is adjustable therefore able to occupy a perforated position for which the window 8 is open ( Fig. 6 ) or a closed position for which the window 8 is closed ( Fig. 7 ). This first pivot 11 and the second pivot 13 are spaced apart from each other by a given measurement. During the sliding of the curtain, the relative position between these pivots 11, 13 changes in the manner of a lever acting to ensure the rotation of the swiveling wing 10.

Conformément à l'invention, le premier pivot 11 et le deuxième pivot 13 sont agencés de manière que d'une part, en l'absence d'un effort exercé par la lame supérieure sur l'aile orientable 10, l'effet du poids P du rideau exercé sur la partie inférieure du support 9 de cette aile orientable, amène le premier pivot 11 et le deuxième pivot 13 à occuper une position sensiblement superposée de sorte que l'aile occupe sa position ajourée, et que d'autre part, l'application d'un effort de poussée M par la lame supérieure sur l'aile orientable 10 entraîne un décalage latéral d entre le premier pivot 11 et le deuxième pivot 13 de sorte que cette aile orientable 10 occupe sa position fermée. Comme cela sera mieux compris dans la suite de la description, l'aile orientable 10 occupe sa position ajourée par le poids du rideau situé en dessous de ladite lame tandis que l'aile orientable 10 occupe sa position fermée sous l'effet d'un effort de poussée exercé par la lame supérieure à cette lame et venant du tambour d'entraînement 5. According to the invention, the first pivot 11 and the second pivot 13 are arranged so that on the one hand, in the absence of an effort exerted by the upper blade on the swiveling wing 10, the effect of the weight P of the curtain exerted on the lower part of the support 9 of this orientable wing, causes the first pivot 11 and the second pivot 13 to occupy a substantially superimposed position of so that the wing occupies its perforated position, and that on the other hand, the application of a thrust force M by the upper blade on the swiveling wing 10 causes a lateral shift d between the first pivot 11 and the second pivot 13 so that this orientable wing 10 occupies its closed position. As will be better understood in the following description, the swivel wing 10 occupies its open position by the weight of the curtain located below said blade while the swivel wing 10 occupies its closed position under the effect of a thrust force exerted by the upper blade to this blade and coming from the driving drum 5.

Tel que cela ressort plus précisément des figures 4 à 7 , l'aile orientable 10 comporte pour définir le premier pivot 11, un premier crochet 14 et un deuxième crochet 15 arrondis selon des sens opposés. Le premier crochet 14 s'engage dans un évidement 16 formé par un crochet 17 porté par la partie supérieure du support 9 et engagé à l'intérieur du deuxième crochet 14. Le deuxième crochet 15 s'étend autour du côté extérieur du crochet 17 porté par le support 9. Lors de la rotation de l'aile orientable 10, le premier crochet 14 est en appui à l'intérieur du crochet 17 du support 9. As more specifically Figures 4 to 7 , the swiveling wing 10 comprises for defining the first pivot 11, a first hook 14 and a second hook 15 rounded in opposite directions. The first hook 14 engages in a recess 16 formed by a hook 17 carried by the upper part of the support 9 and engaged inside the second hook 14. The second hook 15 extends around the outside of the hook 17 carried by the support 9. During the rotation of the swiveling wing 10, the first hook 14 is supported inside the hook 17 of the support 9.

L'aile orientable 10 comporte pour définir le deuxième pivot 13, un troisième crochet 19 arrondi selon un sens opposé au deuxième crochet 15. Ce troisième crochet 19 coopère avec un crochet 21 porté par la partie inférieure du support 9 appartenant à la lame supérieure voisine. Ce crochet 21 porté par la partie inférieure du support 9 de la lame supérieure est arrondi selon un sens opposé au troisième crochet 19. L'application d'un effort de poussée M par la lame supérieure sur l'aile orientable 10 entraîne un déplacement du deuxième pivot 13, vers le bas et un écartement latéral par rapport au premier pivot 11 provoquant le pivotement de l'aile orientable 10 afin d'occuper sa position fermée. Ainsi, en position fermée de l'aile orientable 10, la distance d prise horizontalement entre le premier pivot 11 et le deuxième pivot 13 est maximale tandis qu'en position ajourée de l'aile orientable 10, la distance d est pratiquement nulle puisque les pivots 11, 13 sont pratiquement alignés verticalement.The swiveling wing 10 comprises for defining the second pivot 13, a third hook 19 rounded in a direction opposite to the second hook 15. This third hook 19 cooperates with a hook 21 carried by the lower part of the support 9 belonging to the neighboring upper blade . This hook 21 carried by the lower part of the support 9 of the upper blade is rounded in a direction opposite to the third hook 19. The application of a thrust force M by the upper blade on the swiveling wing 10 causes a movement of the second pivot 13, downwards and a lateral spacing relative to the first pivot 11 causing pivoting of the swiveling wing 10 to occupy its closed position. Thus, in the closed position of the steerable wing 10, the gripping distance horizontally between the first pivot 11 and the second pivot 13 is maximum while in the open position of the steerable wing 10, the distance d is practically zero since the pivots 11, 13 are practically aligned vertically.

Selon une caractéristique avantageuse de réalisation, le support 9 de chaque lame orientable 2o comporte un profilé inférieur 23 à partir duquel s'élèvent au moins deux bras latéraux 24 pourvus à leurs parties supérieures des crochets 17. Dans l'exemple de réalisation illustré sur les dessins, le profilé inférieur 23 comporte une gorge 25 ouverte vers le haut et débouchant aux extrémités du profilé inférieur pour le montage des bras latéraux 24. Chaque bras latéral 22 est réalisé par une plaquette pourvue à sa partie inférieure, d'une nervure 26 d'insertion à l'intérieur de la gorge 25 du profilé inférieur 23. According to an advantageous characteristic of embodiment, the support 9 of each steerable blade 2o comprises a lower section 23 from which rise at least two lateral arms 24 provided at their upper parts of the hooks 17. In the exemplary embodiment illustrated in FIGS. drawings, the lower profile 23 has a groove 25 open upwards and opening at the ends of the lower profile for mounting the lateral arms 24. Each side arm 22 is formed by a plate provided at its lower part, a rib 26 d insertion into the groove 25 of the lower section 23.

Chaque bras latéral 24 est fixé pour être positionné à chacune des extrémités du profilé inférieur, par un élément 28 de fixation et de guidage monté dans les glissières verticales 4. Les éléments 28 sont fixés sur les extrémités du profilé inférieur 23 et comporte chacun un trou 29 de passage pour une vis venant s'ancrer dans la nervure 26 du bras latéral 24. Ces éléments 28 qui s'étendent ainsi en saillie de part et d'autre de la lame orientable, sont aménagés pour assurer le guidage en coulissement du rideau dans les glissières verticales 4. Each lateral arm 24 is fixed to be positioned at each end of the lower profile, by a fixing and guiding element 28 mounted in the vertical slideways 4. The elements 28 are fixed on the ends of the lower profile 23 and each has a hole 29 for passing a screw anchored in the rib 26 of the lateral arm 24. These elements 28 which thus extend projecting on either side of the swiveling blade, are arranged to ensure the sliding guide of the curtain in the vertical slides 4.

Les bras latéraux 24 sont écartés entre eux d'une distance plus ou moins grande délimitant la largeur de la fenêtre 8. L'aile orientable 10 est montée articulée sur ces bras latéraux 24 pour s'étendre entre eux et permettre, par son panneau principal 10a, de fermer cette fenêtre 8 lorsque l'aile orientable est en position fermée. Les bras latéraux 24 sont pourvus à leurs extrémités supérieures opposées de celles pourvues des nervures 26, des crochets 17 coopérant avec l'aile orientable 10 pour définir le premier pivot 11. Avantageusement, l'aile orientable 10 comporte à sa partie inférieure, une rainure 31 d'insertion pour un joint d'étanchéité destiné, en position fermée de l'aile, à coopérer avec le profilé inférieur 23 ( Fig. 5).The lateral arms 24 are separated from each other by a greater or lesser distance delimiting the width of the window 8. The orientable wing 10 is articulated on these lateral arms 24 to extend between them and allow, by its main panel 10a, to close this window 8 when the swiveling wing is in the closed position. The lateral arms 24 are provided at their opposite upper ends with those provided with the ribs 26, hooks 17 cooperating with the swiveling wing 10 to define the first pivot 11. Advantageously, the swiveling wing 10 has at its lower part a groove 31 insertion for a seal intended, in the closed position of the wing, to cooperate with the lower profile 23 ( Fig. 5 ).

Comme déjà expliqué, l'aile orientable 10 comporte à partir de sa face interne dirigée en direction du support 9, le premier crochet 14 et le deuxième crochet 15. Selon une variante avantageuse de réalisation, ces crochets 14, 15 s'étendent selon toute la longueur de l'aile mais coopèrent avec le crochet 17 des bras latéraux 24 uniquement dans les zones d'extrémités de l'aile orientable.As already explained, the steerable wing 10 comprises from its inner face directed towards the support 9, the first hook 14 and the second hook 15. According to an advantageous embodiment, these hooks 14, 15 extend in all directions. the length of the wing but cooperate with the hook 17 of the lateral arms 24 only in the end zones of the swiveling wing.

Selon une caractéristique avantageuse de réalisation, l'aile orientable 10 est un profilé dont le panneau principal se présente sous la forme d'un caisson. Avantageusement, l'aile orientable 10 est pourvue latéralement d'embouts 32 de finition ou de fermeture du caisson du panneau principal 10a, fixés par des vis dans l'aile orientable 10. Avantageusement, ces embouts 32 sont munis à leur partie supérieure, d'une extension latérale 33 destinée à être montée sur les bras latéraux et en particulier sur le crochet 17. Une telle disposition permet le montage articulée de l'aile orientable 10 sur le support tout en utilisant pratiquement toute la longueur de l'aile orientable pour fermer la fenêtre 8. According to an advantageous feature of embodiment, the swivel wing 10 is a profile whose main panel is in the form of a box. Advantageously, the swiveling wing 10 is provided laterally with end caps 32 for finishing or closing the box of the main panel 10a, fixed by screws in the swiveling wing 10. Advantageously, these end pieces 32 are provided at their upper part, with a lateral extension 33 intended to be mounted on the lateral arms and in particular on the hook 17. Such an arrangement allows the articulated mounting of the swiveling wing 10 on the support while using practically the entire length of the swiveling wing for close the window 8.

Il est à noter que dans le cas de la réalisation d'une fenêtre 8 de grande longueur, la gorge 25 du profilé inférieur est apte à recevoir un ou plusieurs bras intermédiaires 34 montés entre les deux bras latéraux 24 permettant de maintenir la rigidité de la lame orientable ( Fig. 8 ).It should be noted that in the case of the realization of a window 8 of great length, the groove 25 of the lower profile is adapted to receive one or more intermediate arms 34 mounted between the two lateral arms 24 to maintain the rigidity of the steerable blade ( Fig. 8 ).

Comme déjà expliqué, l'aile orientable 10 comporte à partir de sa face externe dirigée à l'opposé du support 9, le troisième crochet 19 qui s'étend de préférence selon toute la longueur de l'aile orientable 10. Ce troisième crochet 19 coopère avec le crochet 21 aménagé à la partie inférieure du profilé inférieur 23 et sur toute sa longueur, définissant ainsi le deuxième pivot 13. As already explained, the steerable wing 10 comprises from its outer face directed away from the support 9, the third hook 19 which preferably extends along the entire length of the swiveling wing 10. This third hook 19 cooperates with the hook 21 arranged at the lower part of the lower profile 23 and over its entire length, thus defining the second pivot 13.

Il est à noter que ce deuxième pivot 13 constitue l'articulation entre une lame orientable et une lame supérieure consécutive de type orientable ou fixe. En effet, dans le cas où la lame supérieure voisine à une lame orientable est fixe alors la lame supérieure fixe 2f comporte aussi un profilé inférieur 23 muni d'un crochet 21 ( Fig. 6 et 7 ). La gorge 25 de ce profilé inférieur 23 est destiné à coopérer avec un crochet d'articulation 35 porté par la partie inférieure de la lame supérieure fixe.It should be noted that this second pivot 13 constitutes the articulation between an orientable blade and a subsequent upper blade of orientable or fixed type. Indeed, in the case where the upper blade adjacent to an orientable blade is fixed then the upper fixed blade 2f also comprises a lower profile 23 provided with a hook 21 ( Fig. 6 and 7 ). The groove 25 of this profile lower 23 is intended to cooperate with a hinge 35 carried by the lower part of the fixed upper blade.

Dans le même sens, dans le cas où la lame inférieure voisine à une lame orientable est fixe alors la lame inférieure fixe 2f comporte dans sa partie supérieure, un crochet supérieur 19' analogue au troisième crochet 19 et adapté pour coopérer avec le crochet 21 du profilé inférieur 23. Ce crochet supérieur 19' d'une lame fixe 2f et le troisième crochet 19 présentent des arrondis de sens contraire. Lorsque cette lame fixe est articulée avec une lame fixe inférieure, alors cette lame fixe comporte dans sa partie inférieure, un crochet inférieur 21' analogue au crochet 21 du profilé inférieur 23 et destiné à coopérer avec un crochet supérieur 19' de lame fixe inférieure. Ce crochet inférieur 21' et le crochet supérieur 19' présentent des arrondis de sens contraire. Il est ainsi réalisé un rideau 3 comportant des lames superposées fixes ou orientables, articulées successivement entre-elles.In the same direction, in the case where the lower blade adjacent to an orientable blade is fixed then the fixed lower blade 2f comprises in its upper part, an upper hook 19 ' similar to the third hook 19 and adapted to cooperate with the hook 21 of the lower section 23. This upper hook 19 ' of a fixed blade 2f and the third hook 19 have roundings of opposite direction. When this fixed blade is articulated with a lower fixed blade, then this fixed blade has in its lower part, a lower hook 21 ' similar to the hook 21 of the lower profile 23 and intended to cooperate with a lower hook 19' lower fixed blade. This lower hook 21 ' and the upper hook 19' have roundings of opposite direction. It is thus realized a curtain 3 comprising fixed or adjustable superimposed blades, articulated successively between them.

Le fonctionnement du volet roulant conforme à l'invention découle directement de la description qui précède.The operation of the shutter according to the invention follows directly from the foregoing description.

A partir d'une position entièrement enroulée du rideau autour du tambour 5, le tambour d'entraînement 5 est commandé en rotation par la commande agissant pour assurer le coulissement descendant du rideau pour l'amener jusqu'à la butée basse B. Dès qu'une lame orientable 2o quitte le tambour c'est à dire qu'elle se retrouve en position suspendue, alors l'aile orientable 10 de cette lame vient occuper sa position ajourée en raison de l'application sur le support 9 de ladite lame orientable, du poids P de la partie du rideau située jusqu'à l'extrémité inférieure du rideau. Il doit être compris que lors du coulissement descendant du rideau, les ailes orientables 10 s'ouvrent successivement en sortie du tambour d'enroulement 5 et restent en position ajourée tant qu'elles sont soumises uniquement à la gravité.From a fully wound position of the curtain around the drum 5, the driving drum 5 is controlled in rotation by the control acting to ensure the sliding down of the curtain to bring it to the bottom stop B. As soon as a steerable blade 2o leaves the drum that is to say that it is in the suspended position, then the swivel wing 10 of this blade comes to occupy its open position due to the application on the support 9 of said swivel blade , weight P of the part of the curtain located to the lower end of the curtain. It should be understood that during the downward sliding of the curtain, the steerable wings 10 open successively at the exit of the winding drum 5 and remain in open position as long as they are subjected only to gravity.

Lorsque la lame d'extrémité inférieure arrive sur la butée basse B, la poursuite du coulissement descendant du rideau 3 conduit à amener successivement à partir de la lame inférieure, les ailes orientables 10 des lames à occuper leur position fermée. En effet, l'aile orientable 10 d'une lame orientable reçoit un effort de poussée F par la lame supérieure de sorte que l'aile orientable vient occuper sa position fermée. Ainsi, les lames orientables 2o se ferment successivement en partant du bas du rideau et en remontant vers le haut du rideau. Lorsque toutes les lames orientables 2o sont en position fermée, le tambour 5 est arrêté et le rideau 3 est dans une position d'occultation totale.When the lower end blade reaches the lower stop B, the continuation of the downward sliding of the curtain 3 leads successively to bring from the lower blade, the orientable wings 10 of the blades to occupy their closed position. Indeed, the swiveling wing 10 of an orientable blade receives a thrust force F by the upper blade so that the swivel wing comes to occupy its closed position. Thus, the steerable blades 2o are closed successively starting from the bottom of the curtain and up to the top of the curtain. When all the adjustable blades 2o are in the closed position, the drum 5 is stopped and the curtain 3 is in a total occlusion position.

Pour permettre d'ouvrir les fenêtres 8 d'aération et de passage de la lumière, le tambour d'entraînement 5 est commandé en rotation par la commande pour assurer le coulissement ascendant du rideau 3 sur une course limitée afin d'amener successivement à partir de la lame orientable supérieure et pour un nombre déterminé de lames orientables suivantes, les ailes orientables 10 des lames à occuper leur position ouverte. En effet, l'enroulement du rideau autour du tambour 5 conduit à la suppression de l'effort exercé par la lame supérieure voisine à la lame orientable située la plus haute ou la plus proche du tambour 5. Ainsi, les lames orientables 2o s'ouvrent successivement à partir du haut du rideau en direction du bas du rideau. L'arrêt du coulissement permet de moduler le nombre de lames orientables placées en position ajourée.In order to open the windows 8 of ventilation and light passage, the drive drum 5 is rotated by the control to ensure the upward sliding of the curtain 3 on a limited stroke in order to successively bring from of the upper swivel blade and for a number of successive swiveling blades, the swiveling wings 10 of the blades to occupy their open position. Indeed, the winding of the curtain around the drum 5 leads to the suppression of the force exerted by the adjacent upper blade to the swiveling blade located highest or closest to the drum 5. Thus, the swiveling blades 2o s' open successively from the top of the curtain towards the bottom of the curtain. Stopping the sliding makes it possible to modulate the number of orientable blades placed in the perforated position.

L'invention n'est pas limitée aux exemples décrits et représentés car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the examples described and shown because various modifications can be made without departing from its scope.
