Description

Domaine techniqueTechnical area

La présente invention concerne les stores à lamelles empilables et en particulier un système d'indexation et d'aiguillage des lamelles.The present invention relates to blinds with stackable slats and in particular to a system for indexing and switching the slats.

Etat de la techniqueState of the art

Les stores occultant les ouvertures des bâtiments sont traditionnellement composés de lames articulées les unes aux autres et enroulées autour d'un axe d'enroulement. Ils sont souvent dénommés volets roulants. Parmi les différents types de volets roulants, une solution consiste à empiler les lames du volet deux à deux dans un bac de réception, au lieu de les enrouler intégralement autour de l'axe d'enroulement. Cette disposition évite de devoir prévoir un grand diamètre disponible pour l'enroulement des lames et est donc plus compacte. Un enjeu important de ces arrangements est de pouvoir disposer les lames correctement dans le bac de réception.The blinds obscuring the openings of the buildings are traditionally composed of slats hinged to each other and rolled up around a winding axis. They are often referred to as roller shutters. Among the different types of roller shutters, one solution consists in stacking the slats of the shutter two by two in a receiving tray, instead of winding them entirely around the winding axis. This arrangement avoids having to provide a large diameter available for winding the blades and is therefore more compact. An important issue with these arrangements is to be able to arrange the slides correctly in the receiving tray.

Le document CH606751 décrit un système comprenant des moyens d'indexation des lames à l'aide d'une bascule déviée par les lames du volet et reliée à un ressort de rappel. Les lames sont conçues de sorte à agir sur la bascule à leur passage. Une lame sur deux comporte un dispositif permettant d'actionner la bascule et d'orienter les lames dans le bac.The document CH606751 describes a system comprising means for indexing the slats using a rocker deflected by the slats of the shutter and connected to a return spring. The blades are designed so as to act on the rocker as they pass. Every other slat has a device for activating the rocker and orienting the slats in the tray.

De manière similaire, le document EP3176356 décrit un système comprenant une came actionnée par le passage des lames et permettant de les guider deux à deux dans le bac de réception.Similarly, the document EP3176356 describes a system comprising a cam actuated by the passage of the blades and making it possible to guide them two by two into the receiving tray.

Ces dispositifs présentent l'inconvénient d'être spécifiques d'un certain type de lames. En particulier, une lame sur deux est dotée d'un dispositif interagissant avec une clavette ou une came pour la faire basculer. Les lames et le dispositif d'aiguillage doivent donc être assortis. Il en résulte que chaque type de volet roulant fonctionne avec un type de lame spécifique. Le remplacement des lames usagées peut alors se révéler difficile, voire impossible dans le cas où les lames correspondantes ne sont plus disponibles. Le prix des lames peut en outre représenter un surcoût dans l'entretien de tels volets.These devices have the drawback of being specific to a certain type of blade. In particular, one out of two blades is provided with a device interacting with a key or a cam to cause it to tilt. The blades and the switching device must therefore be matched. As a result, each type of roller shutter works with a specific type of slat. Replacing worn blades may then prove difficult, or even impossible if the corresponding blades are no longer available. The price of the blades can also represent an additional cost in the maintenance of such shutters.

Un autre inconvénient de tels arrangements est que l'aiguillage est effectué par les lames elles-mêmes. Avec l'usage, elles peuvent prendre du jeu dans les guides, se décaler, prendre du biais, et interagir avec les cames de manière moins fiable. Il en résulte des erreurs d'aiguillage ou des blocages.Another disadvantage of such arrangements is that the switching is done by the blades themselves. With use, they can loosen in the guides, shift, become skewed, and interact with the cams less reliably. This results in switching errors or blockages.

Un autre inconvénient des dispositifs précités est la nécessité d'inclure des pièces intermédiaires, notamment pour le rappel des cames ou clavettes permettant l'aiguillage. De telles pièces incluent des ressorts ou des leviers, ou d'autres éléments mécaniques qui représentent autant de sources d'usure et de défaillances.Another drawback of the aforementioned devices is the need to include intermediate parts, in particular for recalling the cams or keys allowing the switching. Such parts include springs or levers, or other mechanical elements which represent as many sources of wear and failures.

Il apparaît donc nécessaire de remédier à ces lacunes.It therefore seems necessary to remedy these shortcomings.

Bref résumé de l'inventionBrief summary of the invention

Un but de la présente invention est de proposer un volet roulant exempt des lacunes exposées ci-dessus. En particulier, il s'agit de proposer un volet roulant dont les lames sont standard et peuvent s'adapter indifféremment à la plupart des autres volets roulants.An object of the present invention is to provide a roller shutter free of the shortcomings set out above. In particular, it is a matter of offering a roller shutter whose slats are standard and can be adapted to most other roller shutters.

Un autre but de l'invention est de proposer un système d'aiguillage pour un volet roulant qui ne soit pas dépendant du passage des lames, autrement dit, non activé par les lames elles-mêmes.Another object of the invention is to provide a switching system for a rolling shutter which is not dependent on the passage of the slats, in other words, not activated by the slats themselves.

Un autre but de la présente invention est de proposer un système d'aiguillage pour un volet roulant exempt de pièces de rappel, tels que des ressorts.Another object of the present invention is to provide a switching system for a rolling shutter free of return parts, such as springs.

Selon l'invention, ces buts sont atteints notamment au moyen du volet roulant et du système d'aiguillage et d'indexage objets des revendications indépendantes et détaillés dans les revendications qui en dépendent.According to the invention, these objects are achieved in particular by means of the rolling shutter and the switching and indexing system which are the subject of the independent claims and detailed in the claims which depend thereon.

En particulier, le volet roulant objet de la présente description comprend un axe d'enroulement dont chacune des extrémités est maintenue par un dispositif de maintien permettant sa rotation. Le volet comporte un bac de réception adapté à accueillir à plat les lames lors de l'ouverture du volet. Le volet comporte également un élément d'aiguillage à chacune de ses extrémités, fixé de manière à pouvoir pivoter. Il comporte en outre une pièce mobile en rotation à chaque extrémité de l'axe d'enroulement et solidaire de l'axe d'enroulement. La pièce mobile présente une géométrie faisant office de came. Elle coopère avec l'élément d'aiguillage de sorte à le faire pivoter alternativement d'une première position à une seconde position en fonction de ses positions angulaires, et des positions angulaires de l'axe d'enroulement.In particular, the roller shutter which is the subject of the present description comprises a winding shaft, each of the ends of which is held by a holding device allowing it to rotate. The shutter has a receiving tray adapted to receive the blades flat when the shutter is opened. The shutter also has a switching element at each of its ends, fixed so as to be able to pivot. It further comprises a rotatable part at each end of the winding shaft and secured to the winding shaft. The moving part has a geometry acting as a cam. It cooperates with the switching element so as to cause it to pivot alternately from a first position to a second position as a function of its angular positions, and of the angular positions of the winding axis.

Les pièces mobiles comprennent notamment une gorge continue et globalement circulaire, comprenant une première portion en arc de cercle ayant un premier diamètre et une seconde portion en arc de cercle ayant un second diamètre différent du premier.The moving parts include in particular a continuous and generally circular groove, comprising a first portion in an arc of a circle having a first diameter and a second portion in an arc of a circle having a second diameter different from the first.

L' élément d'aiguillage comprenant une aiguille en position terminale adaptée à l'aiguillage des lames du volet. Il comporte en outre un ergot coopérant avec la gorge de la pièce mobile. L'élément d'aiguillage comporte également un point de fixation sur lequel il peut pivoter entre une première position et une seconde position correspondant chacune à l'un des diamètres de la gorge de la pièce mobile. L'aiguille se prolonge de part et d'autre de l'élément d'aiguillage, formant deux chants opposés adaptés à guider l'extrémité des lames.The switching element comprising a needle in the terminal position suitable for switching the blades of the shutter. It further comprises a lug cooperating with the groove of the moving part. The switching element also comprises a fixing point on which it can pivot between a first position and a second position each corresponding to one of the diameters of the throat of the moving part. The needle extends on both sides on the other side of the switching element, forming two opposite edges adapted to guide the end of the blades.

La gorge des pièces mobiles comprenant des décrochements assurant la continuité entre les portions en arc de cercle et permettant le passage de l'élément d'aiguillage de l'une à l'autre de ses première et seconde positions. Elle comporte en l'occurrence deux décrochements approximativement diamétralement opposés par rapport à l'axe de rotation de la pièce mobile.The throat of the moving parts comprising recesses providing continuity between the arcuate portions and allowing passage of the switching element from one to the other of its first and second positions. It comprises in this case two recesses approximately diametrically opposed with respect to the axis of rotation of the moving part.

Les pièces mobiles en rotation sont dimensionnées de sorte que la longueur des portions en arc de cercle correspond chacune à la largeur de deux lames contigües. Elles comprennent un évidement central cerné d'une portion circulaire comportant un ou plusieurs éléments de connexion avec l'embout de l'axe d'enroulement de sorte à être entrainée par l'axe d'enroulement. La géométrie de l'extrémité de l'axe d'enroulement est complémentaire de celle des éléments de connexion. Les éléments de connexion sont de préférence disposés de manière non symétrique de sorte à n'autoriser qu'une seule position relative de l'axe d'enroulement et de la pièce mobile.The rotating parts are dimensioned so that the length of the arcuate portions each corresponds to the width of two contiguous blades. They comprise a central recess surrounded by a circular portion comprising one or more connection elements with the tip of the winding shaft so as to be driven by the winding shaft. The geometry of the end of the winding shaft is complementary to that of the connection elements. The connection elements are preferably arranged asymmetrically so as to allow only one relative position of the winding axis and of the moving part.

Les dispositifs de maintien, disposés aux extrémités de l'axe d'enroulement, comprennent chacun un canal frontal permettant de guider les lames autour de l'axe d'enroulement vers une position d'aiguillage, où le canal frontal se divise en deux canaux d'aiguillage alternativement obturés par l'élément d'aiguillage. Les lames sont connectées les unes aux autres par leurs bords longitudinaux. Elles sont de préférence toutes identiques et dépourvues de dispositifs d'aiguillage.The holding devices, arranged at the ends of the winding axis, each comprise a front channel allowing the blades to be guided around the winding axis towards a switching position, where the front channel is divided into two channels switching alternately closed by the switching element. The blades are connected to each other by their longitudinal edges. They are preferably all identical and devoid of switching devices.

Les dispositifs de maintien peuvent se connecter avec des montants latéraux. Le bac de réception peut être fixé entre deux montants latéraux opposés.Holding devices can connect with side uprights. The receiving tray can be fixed between two opposite side uprights.

Les montants latéraux peuvent comporter des moyens de guidage des lames disposés dans la continuité des canaux d'aiguillage. Ils peuvent en outre comporter un dispositif de réglage permettant de moduler la distance entre le bac de réception et l'axe d'enroulement.The side uprights may comprise means for guiding the blades arranged in the continuity of the switching channels. They may also comprise an adjustment device making it possible to modulate the distance between the receiving tray and the winding axis.

La présente description couvre en particulier le système d'aiguillage et d'indexation d'un volet roulant dont les lames sont identiques et dépourvues de dispositif d'aiguillage. Le système d'indexation comporte au moins une pièce mobile en rotation et au moins un élément d'aiguillage tels que définis ici.This description covers in particular the switching and indexing system of a rolling shutter whose slats are identical and have no switching device. The indexing system comprises at least one rotatable part and at least one switching element as defined here.

Cette solution présente notamment l'avantage par rapport à l'art antérieur d'une fiabilité accrue et d'un coût d'entretien avantageux. D'autres avantages apparaitront au cours de la description ci-après.This solution notably has the advantage over the prior art of increased reliability and advantageous maintenance costs. Other advantages will become apparent during the description below.

Le volet roulant désigne ici tout dispositif d'occultation d'ouverture de bâtiment comportant un axe d'enroulement et des lames liées entre elles et articulées entraînées par l'axe d'enroulement et stockées à plat dans un bac de réception. Le volet roulant selon la présente invention exclut les dispositif exempts de bac de réception et où les lames sont intégralement enroulées autour de l'axe d'enroulement, de manière concentrique.The roller shutter designates here any device for concealing the opening of a building comprising a winding shaft and slats linked together and articulated driven by the winding shaft and stored flat in a receiving tray. The roller shutter according to the present invention excludes devices without a receiving tray and where the slats are fully wound around the winding axis, concentrically.

Exemple(s) de mode de réalisation de l'inventionExample(s) of embodiment of the invention

Un exemple de volet roulant 1 selon la présente invention est schématiquement présenté à la figure 1. Un tel volet roulant 1 comporte un axe d'enroulement 10, lequel est généralement disposé transversalement à l'ouverture du bâtiment correspondante, et en position haute. L'axe d'enroulement 10 est pourvu ou connecté à chacune de ses extrémités à un dispositif de maintien 40, fixe et permettant la rotation de l'axe d'enroulement 10 selon l'axe A. Le dispositif de maintien 40 peut être par exemple fixé à la paroi du bâtiment, dans l'encadrement de l'ouverture, ou encastré dans la paroi du bâtiment, ou intégré dans un ensemble lui-même fixé à la paroi du bâtiment. Le volet roulant 1 peut en outre comporter un montant 30, disposé sur chacun des flancs de l'ouverture du bâtiment. Les montants peuvent servir de guides pour le parcours vertical des lames (non représentées) devant l'ouverture du bâtiment. Le dispositif de maintien 40 et les montant 30 peuvent être associés de sorte à former un ensemble. Par exemple, le dispositif de maintien 40 peut être pourvu d'élément de connexion mécanique 41a, 41b, permettant de le solidariser avec le montant 30 correspondant. A cet effet, les montants 30 peuvent comporter des logements adaptés à recevoir de tels éléments de connexion 41a, 41b. Le volet 1 comporte en outre un bac de réception 20 des lames, qui y sont entreposées à plat, de préférence deux à deux, lors de l'ouverture du volet 1. Les lames sont entraînées par l'axe d'enroulement 10, puis guidées dans le bac de réception 20. Le bac de réception 20 est donc disposé transversalement à l'ouverture du bâtiment, soit parallèlement à l'axe d'enroulement 10 et en position légèrement inférieure, de sorte à recueillir les lames. Le bac de réception 20 peut être fixé ou intégré aux montants 30. Il peut en outre ou alternativement être fixé à la paroi du bâtiment.An example of a roller shutter 1 according to the present invention is schematically presented in figure 1 . Such a roller shutter 1 comprises a winding axis 10, which is generally arranged transversely to the opening of the corresponding building, and in the high position. The winding shaft 10 is provided with or connected at each of its ends to a holding device 40, fixed and allowing the rotation of the winding shaft 10 along the axis A. The holding device 40 can be by example fixed to the wall of the building, in the frame of the opening, or embedded in the wall of the building, or integrated into an assembly itself fixed to the wall of the building. The roller shutter 1 may further comprise an upright 30, arranged on each of the sides of the opening of the building. The uprights can be used as guides for the vertical path of the slats (not shown) in front of the opening of the building. The holding device 40 and the uprights 30 can be associated so as to form an assembly. For example, the holding device 40 can be provided with a mechanical connection element 41a , 41b , making it possible to secure it with the corresponding upright 30. For this purpose, the uprights 30 may comprise housings adapted to receive such connection elements 41a , 41b . The shutter 1 further comprises a tray 20 for receiving the slides, which are stored there flat, preferably two by two, when the shutter is opened. 1. The slats are driven by the winding axis 10, then guided into the receiving tray 20. The receiving tray 20 is therefore arranged transversely to the opening of the building, i.e. parallel to the winding axis 10 and in a slightly lower position, so as to collect the blades. The receiving tray 20 can be fixed or integrated into the uprights 30. It can additionally or alternatively be fixed to the wall of the building.

L'axe d'enroulement 10 peut prendre toute géométrie adaptée à l'entrainement des lames du volet. Il peut être par exemple de section circulaire, ou bien avoir une section angulaire polygonale, telle que carrée ou triangulaire. La longueur des différentes faces, le cas échéant, peut être adaptée à la largeur des lames pour un entrainement optimal. Alternativement ou en plus, l'axe d'entrainement 10 peut comporter un ou plusieurs éléments en relief 11, tels que des rainures longitudinales ou des lèvres en surplomb adaptées à l'entrainement des lames. L'axe d'entrainement 10 comporte à chacune de ses extrémités un embout 12 permettant sa rotation dans le dispositif de maintien 40. L'embout est de préférence de forme globalement cylindrique et peut être tenu par des paliers (non représentés).The winding shaft 10 can take any geometry suitable for driving the blades of the shutter. It may for example be of circular section, or else have a polygonal angular section, such as square or triangular. The length of the different faces, if necessary, can be adapted to the width of the blades for optimal training. Alternatively or in addition, the drive shaft 10 may include one or more elements in relief 11, such as longitudinal grooves or overhanging lips suitable for driving the blades. The drive shaft 10 has at each of its ends a tip 12 allowing it to rotate in the holding device 40. The tip is preferably generally cylindrical in shape and can be held by bearings (not shown).

Chacun des embouts 12 du volet roulant 1 comportent au moins un élément de connexion mécanique permettant d'entrainer en rotation une pièce mobile 50 disposée aux extrémités de l'axe d'entrainement 10. La figure 2 montre une vue latérale d'un exemple de volet roulant 1 selon la présente description. La pièce mobile 50 comporte un évidement central 51 adapté à la géométrie de l'embout 12 de l'axe d'entrainement 10. Selon un mode de réalisation, l'élément de connexion mécanique de l'embout 12 est un ou plusieurs ergots adaptés à s'engrener dans une ou plusieurs rainures 53 aménagées dans l'évidement central 51 de la pièce mobile 50. Une disposition inverse peut être envisagée, où l'évidement central 51 de la pièce mobile 50 est pourvu d'un ou plusieurs ergots et où l'embout 12 de l'axe d'entrainement 10 comporte les rainures adaptées à coopérer avec les ergots, de sorte à entrainer la pièce mobile 50 en rotation lors de la rotation de l'axe d'enroulement 10. L'ensemble ergots/rainures peut être disposé de manière régulière de sorte à former un pignon et une couronne adaptés à s'engrener chacun l'un à l'autre. De préférence, l'élément de connexion mécanique de l'embout 12 est irrégulier, de sorte à constituer un détrompeur. En d'autres termes, le ou les ergots sont disposés de sorte à n'autoriser qu'une seule position relative de l'axe d'enroulement 10 et de la pièce mobile 50. Le terme irrégulier s'entend ici comme non symétrique. Leur irrégularité peut concerner la largeur, la position, la profondeur et tout autre paramètre des éléments impliqués dans la connexion mécanique.Each of the end pieces 12 of the roller shutter 1 comprise at least one mechanical connection element making it possible to rotate a moving part 50 arranged at the ends of the drive shaft 10. The figure 2 shows a side view of an example of roller shutter 1 according to the present description. The moving part 50 includes a central recess 51 adapted to the geometry of the end piece 12 of the drive shaft 10. According to one embodiment, the mechanical connection element of the end piece 12 is one or more lugs adapted to mesh in one or more grooves 53 made in the central recess 51 of the moving part 50. An opposite arrangement can be envisaged, where the central recess 51 of the moving part 50 is provided with one or more lugs and where the tip 12 of the drive shaft 10 has grooves adapted to cooperate with the lugs, so as to drive the movable part 50 in rotation during the rotation of the winding shaft 10. The lug assembly /grooves can be arranged in a regular manner so as to form a pinion and a crown adapted to mesh each to each other. Preferably, the mechanical connection element of the endpiece 12 is irregular, so as to constitute a foolproof device. In other words, the lug(s) are arranged so as to allow only one relative position of the winding axis 10 and of the moving part 50. The term irregular is understood here as non-symmetrical. Their irregularity may relate to the width, position, depth and any other parameter of the elements involved in the mechanical connection.

La pièce mobile 50 s'entend comme une pièce mobile en rotation selon l'axe de rotation A de l'axe d'enroulement 10. Elle ne possède de préférence aucun autre degré de liberté. Elle est en outre solidaire de l'axe d'entrainement 10 de telle manière que les positions angulaires relatives de la pièce mobile 50 et de l'axe d'enroulement 10 restent identiques lors de l'enroulement du volet roulant 1.The movable part 50 is understood as a movable part in rotation along the axis of rotation A of the winding axis 10. It preferably does not have any other degree of freedom. It is also secured to the drive shaft 10 in such a way that the relative angular positions of the movable part 50 and the winding shaft 10 remain identical when rolling up the roller shutter 1.

La pièce mobile 50 a une forme globalement plane, dans un plan perpendiculaire à l'axe de rotation A de l'axe d'enroulement 10. La figure 3 montre un exemple détaillé de la pièce mobile 50. Elle se caractérise par la présence d'une gorge 55 globalement circulaire disposée sur l'une des faces de la pièce mobile 50. La gorge 55 est de préférence en position périphérique de la pièce mobile 50. Elle n'a cependant pas nécessairement la même géométrie que la périphérie 54 de la pièce mobile 50. La gorge 55 comporte une première portion en arc de cercle 59a et une seconde portion en arc de cercle 59b de diamètres différents. En particulier le diamètre de la première portion 59a peut être inférieur à celui de la seconde portion 59b, ou inversement. Cela se matérialise par la présence d'un premier décrochement 55a et d'un second décrochement 55b, assurant la continuité de la gorge 55 sur la face de la pièce mobile 50. De préférence, la premier décrochement 55a et le second décrochement 55b sont diamétralement opposés, de sorte que la première portion en arc de cercle 59a occupe approximativement la moitié de la périphérie 54 de la pièce mobile 50 et la seconde portion en arc de cercle 59b en occupe l'autre moitié.The moving part 50 has a generally planar shape, in a plane perpendicular to the axis of rotation A of the winding axis 10. The picture 3 shows a detailed example of the moving part 50. It is characterized by the presence of a generally circular groove 55 arranged on one of the faces of the moving part 50. The groove 55 is preferably in the peripheral position of the moving part 50 However , it does not necessarily have the same geometry as the periphery 54 of the moving part 50. The groove 55 comprises a first portion in an arc of a circle 59a and a second portion in an arc of a circle 59b of different diameters. In particular, the diameter of the first portion 59a can be smaller than that of the second portion 59b, or vice versa. This is materialized by the presence of a first recess 55a and a second recess 55b, ensuring the continuity of the groove 55 on the face of the moving part 50. Preferably, the first recess 55a and the second recess 55b are diametrically opposed, so that the first arcuate portion 59a occupies approximately half of the periphery 54 of the moving part 50 and the second arcuate portion 59b occupies the other half.

La gorge 55 est destinée à recevoir l'ergot 64 d'un élément d'aiguillage 60 (figure 4). Elle est donc de forme régulière adaptée à laisser glisser un tel ergot 64 lors de sa rotation. La forme régulière signifie en particulier que la largeur et la profondeurs sont constantes tout au long de la gorge.The groove 55 is intended to receive the lug 64 of a switching element 60 ( figure 4 ). It is therefore of regular shape suitable for allowing such a lug 64 to slide during its rotation. The regular shape in particular means that the width and depth are constant throughout the groove.

La pièce mobile 50 peut être pleine, de sorte à former un disque, tel que présenté à la figure 2. Alternativement, elle peut être ajourée sur une ou plusieurs portions et comporter ainsi un ensemble de rayons 58 et d'évidements 57. La pièce mobile 50 comporte dans tous les cas une portion circulaire 52 cernant l'évidement central 51 et comportant les élément de connexion 53 nécessaires à sa coopération avec l'embout 12 de l'axe d'enroulement 10. The moving part 50 can be solid, so as to form a disc, as presented in picture 2 . Alternatively, it can be perforated on one or more portions and thus comprise a set of spokes 58 and recesses 57. The moving part 50 comprises in all cases a circular portion 52 surrounding the central recess 51 and comprising the connection elements 53 necessary for its cooperation with the tip 12 of the winding shaft 10.

L'élément d'aiguillage 60 est représenté en détails à la figure 4. Il comporte en particulier un point de fixation 62 adapté à le maintenir sur une support fixe. En l'occurrence le support fixe peut être la pièce de maintien 40. L'important est que le point de fixation 62 permette la rotation de l'élément d'aiguillage 60, au moins sur une certaine amplitude angulaire. L'amplitude angulaire peut être comprise entre environ 2° et 40°, ou entre 5° et 30° ou rester de l'ordre de 8° à 20°. L'amplitude angulaire de l'élément d'aiguillage 60 correspond à la course nécessaire pour aiguiller les lames du volet roulant 1, comme décrit ci-après. Selon une mode réalisation, le point de fixation 62 de l'élément d'aiguillage peut être un orifice dans lequel peut s'insérer un axe 45 (figure 6) solidaire d'un support fixe. Alternativement, le point de fixation 62 peut être un axe pouvant s'insérer dans un orifice adapté d'un support fixe. D'autres arrangements équivalents peuvent bien entendus être envisagés. Il est entendu qu'il s'agit d'un point de fixation rotatif.The switching element 60 is shown in detail at figure 4 . It comprises in particular a fixing point 62 adapted to hold it on a fixed support. In this case, the fixed support can be the holding piece 40. The important thing is that the fixing point 62 allows the rotation of the switching element 60, at least over a certain angular amplitude. The angular amplitude can be between approximately 2° and 40°, or between 5° and 30° or remain of the order of 8° to 20°. The angular amplitude of the switching element 60 corresponds to the stroke necessary to switch the slats of the roller shutter 1, as described below. According to one embodiment, the point of attachment 62 of the switching element can be an orifice in which a pin 45 ( figure 6 ) attached to a fixed support. Alternatively, the attachment point 62 can be a pin that can be inserted into a suitable hole in a fixed support. Other equivalent arrangements can of course be envisaged. It is understood that this is a rotary attachment point.

L'élément d'aiguillage 60 comporte un ergot 64 destiné à coopérer avec la gorge 55 de la pièce mobile 50. A cette fin il est de longueur adéquate, adaptée à la profondeur de la gorge 55, et d'épaisseur adaptée à son glissement dans la gorge 55. L'ergot 64 est de préférence disposé à proximité de la partie terminale de l'élément d'aiguillage 60 et à distance de son point de fixation 62. En fonction du débattement désiré de l'élément d'aiguillage, d'autres dispositions relative du point de fixation 62 et de l'ergot 64 peuvent être envisagées. L'ergot 64 est disposé parallèlement à l'axe de rotation de l'élément d'aiguillage autour de son point de fixation 62. En outre, l'ergot 64 et l'axe de rotation de l'élément d'aiguillage 60 sont tous deux parallèles à l'axe de rotation A de l'axe d'enroulement 10. La partie terminale de l'élément d'aiguillage 60 comporte une aiguille 61 adaptée à l'aiguillage des lames. De préférence, la partie terminale fait d'office d'aiguille 61. Elle est alors profilée de sorte à orienter les lames du volet roulant 1 vers l'un ou l'autres des premier 63a et second 63b des chants de l'élément d'aiguillage 60. Les premier et second chants 63a, 63b de l'élément d'aiguillage 60 sont profilés de sorte à guider au mieux les lames. Le premier chant 63a et le second chant 63b peuvent indépendamment l'un de l'autre prendre une forme rectiligne ou arrondie, qui soit concave ou convexe, ou sinueuse. Les chants de l'élément d'aiguillage 60 peuvent par exemple prendre globalement la forme d'une goutte d'eau dont la pointe forme l'aiguille 61. D'autres formes adaptées au guidage des lames peuvent être envisagées.The switching element 60 comprises a lug 64 intended to cooperate with the groove 55 of the movable part 50. To this end it is of adequate length, adapted to the depth of the groove 55, and of thickness adapted to its sliding in the groove 55. The lug 64 is preferably arranged close to the end part of the switching element 60 and at a distance from its attachment point 62. Depending on the desired movement of the switching element, other relative arrangements of the attachment point 62 and the lug 64 can be envisaged. The lug 64 is arranged parallel to the axis of rotation of the switching element around its attachment point 62. In addition, the lug 64 and the axis of rotation of the switching element 60 are both parallel to the axis of rotation A of the winding axis 10. The end part of the switching element 60 comprises a needle 61 adapted to the switching of the blades. Preferably, the end part acts as a needle 61. It is then profiled so as to orient the blades of the roller shutter 1 towards one or the other of the first 63a and second 63b of the edges of the element of referral 60. The first and second edges 63a, 63b of the referral element 60 are profiled so as to best guide the blades. The first edge 63a and the second edge 63b can independently of each other take a rectilinear or rounded shape, which is concave or convex, or sinuous. The edges of the switching element 60 can for example take the overall shape of a drop of water, the tip of which forms the needle 61. Other shapes suitable for guiding the blades can be envisaged.

La figure 5 schématise la coopération de la pièce mobile 50 et de l'élément d'aiguillage 60. Los de la rotation de la pièce mobile 50, entraînée par l'axe d'enroulement 10, la gorge 55 entraine l'ergot 64 de l'élément d'aiguillage 60. Le passage de l'ergot 64 de la première portion en arc de cercle 59a à la second portion en arc de cercle 59b, au niveau du premier décrochement 55a par exemple, fait pivoter l'élément d'aiguillage 60 autour de son point de fixation 62 à une première position angulaire. L'élément d'aiguillage 60 se maintient à cette première position angulaire lors de la rotation de la pièce mobile 50 jusqu'au passage du second décrochement 55b, faisant passer l'ergot 64 depuis la seconde portion en arc de cercle 59b vers la première portion en arc de cercle 59a. L'élément d'aiguillage 60 prend alors une seconde position angulaire. Il est noté que le débattement angulaire de l'élément d'aiguillage 60 dépend de la différence de diamètre entre les première 59a et seconde 59b portion en arc de cercle. Il est également noté que l'élément d'aiguillage 60 pivote à chaque demi-tour de la pièce mobile 50, considérant que les premier 55a et second 55b décrochements sont diamétralement opposés. Il est entendu que le pivotement de l'élément d'aiguillage 60 coïncide avec le passage des lames à guider soit vers son premier chant 63a, soit vers son second chant 63b. En particulier, l'aiguille 61 est suffisamment effilée pour s'insérer dans le jeu naturel qui sépare deux lames contigües et ainsi dévier leur course vers l'un ou l'autre des canaux d'aiguillage. Selon un mode de réalisation, l'aiguille 61 s'inscrit totalement dans le plan de l'élément d'aiguillage 60. L'extrémité des lames glissent ainsi alternativement sur les premier 63a et second 63b chants de l'élément d'aiguillage 60. Selon une variante, l'aiguille 61 est plus large que l'épaisseur de l'élément d'aiguillage 60 ou est déportée au-delà de son plan de sorte que seule l'extrémité de l'aiguille 61 s'immisce entre les lames du volet pour les faire dévier. Les dimensions de l'élément d'aiguillage 60 sont bien entendu adaptées à l'écartement des lames de sorte à pouvoir les orienter efficacement.There figure 5 diagrams the cooperation of the moving part 50 and the switching element 60. Loss of the rotation of the moving part 50, driven by the winding shaft 10, the groove 55 causes the lug 64 of the element switch 60. The passage of the lug 64 from the first portion in an arc of a circle 59a to the second portion in an arc of a circle 59b, at the level of the first recess 55a for example, makes the switch element 60 pivot around from its attachment point 62 to a first angular position. The switching element 60 is maintained in this first angular position during the rotation of the movable part 50 until the passage of the second offset 55b, causing the lug 64 to pass from the second portion in the arc of a circle 59b towards the first arcuate portion 59a. The switching element 60 then assumes a second angular position. It is noted that the angular travel of the switching element 60 depends on the difference in diameter between the first 59a and second 59b portion in the arc of a circle. It is also noted that the switching element 60 pivots with each half-turn of the moving part 50, considering that the first 55a and second 55b setbacks are diametrically opposed. It is understood that the pivoting of the switching element 60 coincides with the passage of the blades to be guided either towards its first edge 63a, or towards its second edge 63b. In particular, the needle 61 is sufficiently tapered to fit into the natural play which separates two contiguous blades and thus to deviate their course towards one or the other of the switching channels. According to one embodiment, the needle 61 fits completely in the plane of the switching element 60. The end of the blades thus slide alternately on the first 63a and second 63b edges of the switching element 60 According to a variant, the needle 61 is wider than the thickness of the switching element 60 or is offset beyond its plane so that only the end of the needle 61 interferes between the shutter blades to deflect them. The dimensions of the switching element 60 are of course adapted to the spacing of the blades so as to be able to orient them effectively.

La pièce mobile 50 et l'élément d'aiguillage 60 peuvent être l'un et l'autre exclusivement faits en matière plastique, tel qu'un plastique dur. En particulier, la gorge 55 et l'ergot 64 sont suffisamment rigides pour dévier le parcours des lames. Les polymères utilisés peuvent néanmoins être sélectionnés de sorte à conserver une souplesse suffisante pour amortir par déformation les éventuelles pressions mécaniques et éviter ainsi de se casser. La pièce mobile 50 et l'élément d'aiguillage 60 peuvent alternativement être l'un et l'autre exclusivement faits en métal, en particulier un métal inoxydable. L'un ou l'autre de la pièce mobile 50 et de l'élément d'aiguillage 60 peuvent être constitués de plusieurs matériaux différents, comprenant notamment différents matières plastique de dureté différente. Par exemple, la partie centrale 52 de la pièce mobile 50, comprenant les éléments de connexion 53 peut être constituée d'un plastique dur ou de métal pour éviter toute déformation. La gorge 55 peut en contrepartie rester plus souple. L'élément d'aiguillage 60 peut être quant à lui constitué en tout ou partie d'un matériau souple permettant d'amortir le contact avec les lames.The moving part 50 and the switching element 60 can both be made exclusively of plastic material, such as a hard plastic. In particular, the groove 55 and the lug 64 are rigid enough to deviate the course of the blades. The polymers used can nevertheless be selected so as to retain sufficient flexibility to dampen any mechanical pressure by deformation and thus avoid breaking. The moving part 50 and the switching element 60 can alternatively both be made exclusively of metal, in particular a stainless metal. One or the other of the moving part 50 and of the switching element 60 can be made of several different materials, including in particular different plastic materials of different hardness. For example, the central part 52 of the moving part 50, comprising the connection elements 53 can be made of a hard plastic or of metal to avoid any deformation. The groove 55 can in return remain more flexible. The switching element 60 can itself be made up in whole or in part of a flexible material making it possible to dampen the contact with the blades.

Selon un mode de réalisation, l'élément d'aiguillage 60 comporte une lèvre 65 qui borde le premier 63a et le second 63b chants, la lèvre 65 s'inscrivant dans le prolongement de l'aiguille 61 (figure 4). La lèvre 65 présente l'avantage de former une butée limitant ou interdisant les éventuels mouvements transversaux des lames du volet roulant 1. L'extrémité des lames viennent ainsi en appui sur les premier 63a et second 63b chants de l'élément d'aiguillage 60 et en butée contre la lèvre 65 qui borde les chants 63a et 63b. L'un ou l'autre de la lèvre 65 ou des chants 63a, 63b peuvent être fait en matière plastique dur ou bien plus souple et permettant d'amortir le contact avec les lames.According to one embodiment, the switching element 60 comprises a lip 65 which borders the first 63a and the second 63b edges, the lip 65 being part of the extension of the needle 61 ( figure 4 ). The lip 65 has the advantage of forming a stop limiting or prohibiting any transverse movements of the slats of the roller shutter 1. The end of the slats thus come to bear on the first 63a and second 63b edges of the switching element 60 and in abutment against the lip 65 which borders the edges 63a and 63b. One or the other of the lip 65 or of the edges 63a, 63b can be made of hard plastic material or much more flexible and allowing the contact with the blades to be dampened.

La pièce mobile 50, et en particulier sa gorge 55, sont dimensionnées de sorte à faire pivoter l'élément d'aiguillage 60 à chaque seconde lame de sorte à orienter les lames par paire dans le bac de réception 20. En d'autres termes, la longueur des première 59a et seconde 59b portions en arc de cercle correspond chacune à la largeur de deux lames contigües. Il en résulte que l'aiguillage des lames est indépendant du passage des lames sur l'élément d'aiguillage 60, qui est activement déplacé par la rotation de l'axe d'enroulement 10. Il en résulte en outre que l'élément d'aiguillage 60 est indexé sur la position angulaire de l'axe d'enroulement 10 et de la pièce mobile 50. La pièce mobile 50 fait office de came permettant de faire pivoter activement l'élément d'aiguillage 60 depuis une première position vers une seconde position et inversement. L'aiguillage des lame est ainsi effectué sans pièces ressort. En outre des lames standard, exemptes de dispositifs d'activation de l'élément d'aiguillage, peuvent être utilisées.The moving part 50, and in particular its groove 55, are dimensioned so as to cause the switching element 60 to pivot at each second blade so as to orient the blades in pairs in the receiving tray 20. In other words , the length of the first 59a and second 59b arcuate portions each corresponds to the width of two contiguous blades. As a result, the switching of the blades is independent of the passage of the blades over the switching element 60, which is actively moved by the rotation of the winding axis 10. It further results from this that the element of the switch 60 is indexed to the angular position of the winding axis 10 and of the moving part 50. The moving part 50 acts as a cam making it possible to actively pivot the switching element 60 from a first position to a second position and vice versa. The switching of the blades is thus carried out without spring parts. In addition, standard blades, free of switch element activation devices, can be used.

La figure 6 montre une vue de profile, schématisée, de l'élément d'aiguillage 60 au sein du volet roulant 1. La pièce mobile 50 n'est ici pas représentée. Le pivotement de l'élément d'aiguillage 60 depuis sa première position vers sa seconde position, et inversement, permet d'orienter le l'extrémité des lames du volet roulant 1 dans un premier canal 44a ou dans un second canal 44b. Les premier 44a et second 44b canaux correspondent par exemple à des rainures ménagées dans la pièce de maintien 40. Les montants 30 peuvent comporter chacun un premier moyen de guidage 34a et un second moyen de guidage 34b, dans la continuité des premier 44a et second 44b canaux de sorte à guider les lames dans le bac de réception à leur position adéquate. Les moyens de guidage 34a, 34b peuvent prendre la forme de rainures dans le montant 30 dans lesquelles l'extrémité des lames peut glisser. Les moyens de guidage 34a, 34b peuvent s'étendre sur toute la longueur du montant 30 correspondant. De préférence, les moyens de guidage 34a, 34b s'étendent sur une distance limitée de sorte à libérer l'extrémité des lames lorsqu'elles sont à proximité du bac de réception 20. Elles peuvent ainsi librement s'empiler horizontalement. La distance séparant les moyens de guidage 34a, 34b correspond approximativement à la largeur du bac de réception de sorte à guider les paires de lames alternativement proche des deux bords opposés du bac de réception 20. There figure 6 shows a profile view, schematically, of the switching element 60 within the roller shutter 1. The moving part 50 is not shown here. The pivoting of the switching element 60 from its first position to its second position, and vice versa, makes it possible to orient the end of the slats of the roller shutter 1 in a first channel 44a or in a second channel 44b. The first 44a and second 44b channels correspond, for example, to grooves made in the retaining part 40. The uprights 30 can each comprise a first guide means 34a and a second guide means 34b, in the continuity of the first 44a and second 44b channels so as to guide the blades in the receiving tray to their correct position. The guide means 34a, 34b can take the form of grooves in the upright 30 in which the end of the blades can slip. The guide means 34a, 34b can extend over the entire length of the upright 30 corresponding. Preferably, the guide means 34a, 34b extend over a limited distance so as to release the end of the blades when they are close to the receiving tray 20. They can thus freely stack horizontally. The distance separating the guide means 34a, 34b corresponds approximately to the width of the receiving tray so as to guide the pairs of blades alternately close to the two opposite edges of the receiving tray 20.

La pièce de maintien 40 peut ainsi faire office de guide pour les lames du volet roulant 1. Elle peut comporter une ouverture 42, permettant de guider les lames dans un canal frontal 43 autour de l'axe d'enroulement 10, lequel fait pivoter l'élément d'aiguillage 60 par l'intermédiaire de la pièce mobile 50, et aiguille les lames vers l'un ou l'autre des premier 44a et second 44b canaux. Le canal 43, en position frontal du volet roulant 1, se divise en position arrière en premier 44a et second 44b canaux. L'aiguille 61 vient alternativement en butée, ou à proximité de la paroi interne du canal 43 de sorte à fermer le passage de l'un ou de l'autre des premier 44a et second 44b canaux.The holding part 40 can thus act as a guide for the slats of the roller shutter 1. It can comprise an opening 42, making it possible to guide the slats in a front channel 43 around the winding axis 10, which pivots the switching element 60 via the moving part 50, and switches the blades to one or the other of the first 44a and second 44b channels. Channel 43, in the front position of roller shutter 1, is divided in the rear position into first 44a and second 44b channels. The needle 61 alternately comes into abutment, or close to the internal wall of the channel 43 so as to close the passage of one or the other of the first 44a and second 44b channels.

Le volet roulant 1 selon la présente invention est donc adapté aux lames standard, toutes identiques et dépourvues de tout dispositif d'aiguillage. En fonction de la longueur du volet roulant 1, c'est-à-dire du nombre de ses lames, l'espace disponible dans le bac de réception 20 peut être modulée. Selon un mode de réalisation particulier, le bac de réception 20 est fixé entre les deux montants 30 opposés. Les montants 30 peuvent être chacun connectés aux dispositifs de maintien 40 correspondant par les éléments de connexion 41a, 41b appropriés (figure 1). Un dispositif de réglage 70 adapté à moduler la distance entre le dispositif de maintien 40 et le montant 30 correspondant peut être prévu. De la sorte, le bac de réception 20 peut être éloigné ou rapproché de l'axe d'enroulement 10 en fonction du volume des lames une fois qu'elles sont empilées dans le bac de réception. Le dispositif de réglage 70 peut par exemple comporter une réglette crantées, disposée sur le dispositif de maintien 40 et coopérant avec un système de crans d'arrêt disposé en vis-à-vis sur le montant 30 correspondant. D'autres dispositifs équivalents peuvent être envisagés.The roller shutter 1 according to the present invention is therefore suitable for standard slats, all identical and devoid of any switching device. Depending on the length of the roller shutter 1, that is to say the number of its blades, the space available in the receiving tray 20 can be modulated. According to a particular embodiment, the receiving tray 20 is fixed between the two uprights 30 opposite. The uprights 30 can each be connected to the corresponding holding devices 40 by the appropriate connection elements 41a, 41b ( figure 1 ). An adjustment device 70 adapted to modulate the distance between the holding device 40 and the corresponding upright 30 can be provided. In this way, the receiving tray 20 can be moved away from or closer to the winding axis 10 depending on the volume of the slides once they are stacked in the receiving tray. The adjustment device 70 can for example comprise a notched strip, arranged on the holding device 40 and cooperating with a system of detents arranged vis-à-vis on the amount 30 corresponding. Other equivalent devices can be envisaged.

L'ensemble formé par la pièce mobile en rotation 50 et l'élément d'aiguillage 60 constitue un système d'indexation de la position des lames du volet roulant dans le bac de réception 20 en fonction de la position angulaire de l'axe d'enroulement 10. L'ensemble formé par la pièce mobile en rotation 50 et l'élément d'aiguillage 60 constitue un dispositif de synchronisation de la déviation des lames avec la position angulaire de l'axe d'enroulement.The assembly formed by the rotatable part 50 and the switching element 60 constitutes a system for indexing the position of the slats of the roller shutter in the receiving tray 20 as a function of the angular position of the axis d winding 10. The assembly formed by the rotatable part 50 and the switching element 60 constitutes a device for synchronizing the deflection of the blades with the angular position of the winding axis.
