Description

La présente invention concerne le domaine des structures déployables.The present invention relates to the field of deployable structures.

La présente invention s'applique notamment, mais non exclusivement, à la réalisation de volets type « volets roulants » destinés à l'occultation de fenêtres, portes ou équivalents.The present invention applies in particular, but not exclusively, to the realization of shutters type "shutters" for the concealment of windows, doors or the like.

De nombreuses structures de volets ou équivalents ont déjà été proposées.Many strut structures or equivalents have already been proposed.

A titre d'exemples non limitatifs, on pourra se référer utilement aux documents FR 2 769 040 , FR 2 560 278 , EP 321 799 , GB 2 023 685 , DE 535 570 , US 5 957 185 , US 4 643 081 , FR 2 506 381 et FR 2 414 613 .By way of non-limiting examples, reference may be made to the documents FR 2 769 040 , FR 2,560,278 , EP 321 799 , GB 2,023,685 , DE 535 570 , US 5,957,185 , US 4,643,081 , FR 2,506,381 and FR 2,414,613 .

On a décrit en particulier dans le document FR 2 414 613 une structure déployable comprenant des éléments en forme de lames indépendants les uns des autres et des moyens de guidage comprenant d'une part un coffre apte à recevoir les éléments en forme de lames dans une disposition empilée et d'autre part un guide qui débouche dans le coffre et qui est adapté pour recevoir les éléments en forme de lames dans une position juxtaposée, les éléments en forme de lames comprenant des moyens d'accrochage mutuel sur leurs bords transversaux à la direction de déplacement des éléments en forme de lames dans le guide.It has been described in particular in the document FR 2,414,613 a deployable structure comprising elements in the form of blades independent of each other and guiding means comprising on the one hand a chest adapted to receive the blade-shaped elements in a stacked disposition and on the other hand a guide which opens into the the trunk and which is adapted to receive the blade-shaped elements in a juxtaposed position, the blade-shaped elements comprising mutual gripping means on their edges transverse to the direction of movement of the blade-shaped elements in the guide .

La structure décrite dans ce document FR 2 414 613 ne donne pas totalement satisfaction. En particulier elle exige une structure d'entraînement complexe, qui nécessite notamment un contre-poids destiné à maintenir l'assemblage en tension et une tringlerie pour assurer les manoeuvres d'ouverture et de fermeture du volet.The structure described in this document FR 2,414,613 does not give complete satisfaction. In particular, it requires a complex drive structure, which requires in particular a counterweight for maintaining the tensioning assembly and a linkage to ensure the opening and closing maneuvers of the shutter.

Le brevet BE 503221 divulgue une structure déployable selon le préambule de la revendication 1.The patent BE 503221 discloses a deployable structure according to the preamble of claim 1.

La présente invention a maintenant pour but de proposer de nouveaux moyens présentant des performances supérieures à celles des dispositifs antérieurs.It is now an object of the present invention to provide novel means having higher performance than previous devices.

Ce but est atteint dans le cadre de la présente invention, grâce à une structure du type précédemment évoquée comprenant des éléments déployables indépendants et des moyens de guidage comprenant d'une part un coffre apte à recevoir les éléments déployables dans une disposition empilée et d'autre part un guide qui débouche dans le coffre et qui est adapté pour recevoir les éléments déployables dans une position juxtaposée, les éléments déployables comprenant des moyens d'accrochage mutuel sur leurs tranches transversales à la direction de déplacement des éléments déployables dans le guide, caractérisée par le fait qu'elle comprend, d'une part, des moyens aptes à interdire un mouvement relatif entre les moyens d'accrochage de deux éléments déployables adjacents lorsque ceux-ci sont positionnés en dehors du coffre, quel que soit le sens de déplacement des éléments déployables dans le guide et, d'autre part, des éléments de guidage adaptés pour imposer aux éléments déployables, dans le coffre, un déplacement selon une direction ayant une composante transversale à la direction longitudinale du guide, ces éléments de guidage étant formés par des moyens de guidage complémentaires prévus respectivement sur les flancs du coffre et sur les flancs en regard des lames.This object is achieved in the context of the present invention, thanks to a structure of the type previously mentioned comprising independent deployable elements and guiding means comprising on the one hand a box adapted to receive the deployable elements in a stacked arrangement and on the other hand a guide which opens into the trunk and which is adapted to receive the deployable elements in a juxtaposed position, the deployable elements comprising mutual attachment means on their slices transverse to the direction of movement of the deployable elements in the guide, characterized in that it comprises, on the one hand, means able to prohibit a relative movement between the attachment means of two adjacent deployable elements when they are positioned outside the box, whatever the direction of movement deployable elements in the guide and, secondly, guiding elements adapted for i depositing the deployable elements in the trunk, a displacement in a direction having a component transverse to the longitudinal direction of the guide, these guide elements being formed by complementary guiding means respectively provided on the sides of the trunk and on the flanks facing blades.

On va décrire dans un premier temps le premier mode de réalisation de la présente invention illustré sur les figures 1 à 3 et 4a à 4f, étant précisé que ce premier mode de réalisation ne fait pas partie des modes de réalisation revendiqués et est seulement décrit ci-après à titre informatif.We will first describe the first embodiment of the present invention illustrated on the Figures 1 to 3 and 4a to 4f , it being specified that this first embodiment is not part of the claimed embodiments and is only described below for information purposes.

Comme indiqué précédemment la structure déployable conforme à la présente invention comprend essentiellement des moyens de guidage 100 et des éléments déployables 200. Elle comprend par ailleurs un système d'entraînement.As indicated above, the deployable structure according to the present invention essentially comprises means for 100 guide and deployable elements 200. It further comprises a drive system.

Les moyens de guidage 100 comprennent un coffre 110 et un guide 150.The guiding means 100 comprise a trunk 110 and a guide 150.

Le guide 150 débouche dans le coffre 110.The guide 150 opens into the trunk 110.

Selon le mode de réalisation non revendiqué illustré sur les figures 1 à 4, le guide 150 est formé de deux glissières 152 parallèles et symétriques par rapport à un plan passant par la direction de déplacement des éléments 200 dans le guide. Ces glissières 152 sont conçues pour recevoir et guider respectivement les bords latéraux des éléments 200.According to the unclaimed embodiment illustrated on the Figures 1 to 4 , the guide 150 is formed of two rails 152 parallel and symmetrical with respect to a plane passing through the direction of movement of the elements 200 in the guide. These slides 152 are designed to receive and guide respectively the lateral edges of the elements 200.

Cependant l'invention s'applique également à des variantes selon lesquelles la structure comprend une glissière unique 152 (disposée alors typiquement non pas sur un bord latéral des éléments 200 mais sur la partie médiane de ceux-ci), ou comprend un nombre de glissière 152 supérieur à deux, ou encore à des variantes selon lesquelles la glissière ou les glissières 152 reçoivent une partie des éléments 200 différente de leur bord latéral.However, the invention also applies to variants according to which the structure comprises a single slideway 152 (then typically arranged not on a lateral edge of the elements 200 but on the middle part thereof), or comprises a number of slides 152 greater than two, or alternatively according to which the slide or the slides 152 receive a part of the elements 200 different from their side edge.

De préférence chaque glissière 152 comporte un canal rectiligne présentant une section droite de largeur constante.Preferably each slideway 152 comprises a rectilinear channel having a cross section of constant width.

En variante néanmoins, chaque glissière 152 peut présenter un profil non pas rectiligne, mais au moins légèrement incurvé.Alternatively, however, each slide 152 may have a profile not rectilinear, but at least slightly curved.

La section droite 154 de chaque glissière 152, considérée transversalement à la direction de déplacement des éléments 200 est complémentaire de celle des éléments 200. Ainsi une fois les moyens d'accrochage 220 en prise, le guide 150 interdit tout déplacement relatif entre deux lames adjacentes 200 dans un sens transversal à la direction du guide. La liaison mécanique entre les lames adjacentes 200, dans le sens longitudinal du guide 150, est quant à elle assurée par les moyens d'accrochage 220 eux-mêmes.The cross section 154 of each slideway 152, viewed transversely to the direction of movement of the elements 200 is complementary to that of the elements 200. Thus once the hooking means 220 in engagement, the guide 150 prohibits any relative displacement between two adjacent blades 200 in a direction transverse to the direction of the guide. The mechanical connection between the adjacent blades 200, in the longitudinal direction of the guide 150, is provided by the attachment means 220 themselves.

Le coffre 110 définit un logement 112 qui s'étend essentiellement dans une direction transversale aux glissières 152.The trunk 110 defines a housing 112 which extends essentially in a direction transverse to the slides 152.

Le guide 150 débouche dans le fond du coffre 110.The guide 150 opens into the bottom of the box 110.

Typiquement une paroi 153 de chaque glissière prolonge ainsi la paroi de fond 114 du coffre 110.Typically a wall 153 of each slide thus extends the bottom wall 114 of the box 110.

Le coffre est délimité, outre la paroi de fond 114 précitée, par deux flancs 120 parallèles entre eux et parallèles à la direction de déplacement des éléments 200 à la fois dans le guide 150 et dans le coffre 110 (l'un de ces flancs 120 est visible sur les figures 1 et 3), par une paroi aval 122 transversale à la direction de déplacement des éléments 200 dans le guide 150 mais parallèle à la direction de déplacement des éléments 200 dans le coffre 110 et par une paroi amont 124 parallèle à la paroi aval 122.The trunk is delimited, in addition to the bottom wall 114 above, by two sides 120 parallel to each other and parallel to the direction of movement of the elements 200 in both the guide 150 and the trunk 110 (one of these flanks 120 is visible on Figures 1 and 3 ), by a downstream wall 122 transverse to the direction of movement of the elements 200 in the guide 150 but parallel to the direction of movement of the elements 200 in the trunk 110 and by an upstream wall 124 parallel to the downstream wall 122.

Le guide 150 se raccorde sur la paroi amont 124. Bien évidemment celle-ci est ajourée en regard du guide 150 pour permettre à ce dernier de déboucher dans le coffre 110.The guide 150 is connected to the upstream wall 124. Obviously it is perforated facing the guide 150 to allow the latter to open into the trunk 110.

On notera que la zone de jonction entre le canal interne du guide 150 et cette paroi amont 124 présente de préférence un chanfrein 126It will be noted that the junction zone between the inner channel of the guide 150 and this upstream wall 124 preferably has a chamfer 126

On a évoqué précédemment des éléments de guidage présentant une disposition oblique par rapport à la direction longitudinale du guide 150, adaptés pour imposer aux éléments déployables 200, dans le coffre 110, une composante transversale à la direction longitudinale du guideGuiding elements having an oblique disposition with respect to the longitudinal direction of the guide 150 have previously been mentioned, adapted to impose on the deployable elements 200, in the box 110, a component transverse to the longitudinal direction of the guide

Selon le mode de réalisation non revendiqué des figures 1 à 4, de tels éléments de guidage oblique sont formés par une inclinaison partielle de la surface interne de la paroi de fond 114 du coffre 110. Plus précisément encore des tels éléments de guidage sont formés par un pan incliné 116. Celui-ci est de préférence plan. Il est formé sur la partie de la paroi de fond 114 la plus éloignée du guide 150. Le pan incliné 116 s'écarte de l'axe de la glissière 152 dans le sens d'un éloignement de cette dernière. L'inclinaison entre le pan 116 et l'axe de la glissière 152 est typiquement de quelques degrés.According to the unclaimed embodiment of the Figures 1 to 4 , such oblique guide elements are formed by a partial inclination of the inner surface of the bottom wall 114 of the box 110. More precisely still such guide elements are formed by an inclined portion 116. This is preferably plane . It is formed on the part of the bottom wall 114 farthest from the guide 150. The inclined face 116 deviates from the axis of the slide 152 in the direction of a distance from the latter. The inclination between the pan 116 and the axis of the slide 152 is typically a few degrees.

En pratique la localisation, la longueur et l'inclinaison du pan incliné 116 sont adaptées de sorte que, comme on le voit sur la figure 4c, qui sera décrite plus en détail par la suite, lorsqu'une lame L2 repose intégralement sur le pan 116, sa structure d'accrochage amont 226 interfère légèrement avec la structure aval 226 complémentaire de la lame adjacente L3 située dans la glissière 150. Ces structures d'accrochage 226 sont portées en prise lorsque la lame L3 ou la lame L2 est sollicitée vers l'extérieur du coffre 110. Au contraire les structures d'accrochage 226 sont désengagées lorsque la lame L3 est sollicitée vers l'intérieur du coffre 110.In practice, the location, the length and the inclination of the inclined face 116 are adapted so that, as seen on the figure 4c , which will be described in more detail later, when a blade L2 rests integrally on the pan 116, its upstream hooking structure 226 slightly interferes with the downstream structure 226 complementary to the adjacent blade L3 located in the slide 150. These attachment structures 226 are engaged when the blade L3 or the blade L2 is biased out of the 110. On the contrary, the attachment structures 226 are disengaged when the blade L3 is urged towards the inside of the box 110.

Selon le mode de réalisation non revendiqué illustré sur les figures 1 à 4 la longueur du guide 150 est adaptée pour recevoir intégralement les éléments 200 en position juxtaposée par leur tranche.According to the unclaimed embodiment illustrated on the Figures 1 to 4 the length of the guide 150 is adapted to fully receive the elements 200 in juxtaposed position by their edge.

On verra cependant par la suite, notamment en regard des figures 12 à 21, que en variante le guide 150 peut posséder une longueur limitée, inférieure à l'amplitude déployée de l'ensemble des éléments 200 dès lors qu'il est prévu des moyens aptes à assurer une immobilisation relative des éléments 200 en dehors du coffre 110.However, we will see later, especially with regard to Figures 12 to 21 as a variant, the guide 150 may have a limited length, less than the expanded amplitude of all the elements 200, provided that means are provided to ensure relative immobilization of the elements 200 outside the box 110.

Ce dernier quant à lui est adapté pour recevoir l'ensemble des éléments 200 en position empilée dans laquelle les éléments 200 sont adjacents par leurs faces latérales principales.The latter meanwhile is adapted to receive all the elements 200 in stacked position in which the elements 200 are adjacent by their main lateral faces.

On notera à l'examen des figures annexées, que de préférence il est prévu dans le coffre 110 des moyens élastiques 300 aptes à solliciter les éléments 200 empilés contre la paroi de fond 114.It will be noted on examination of the appended figures, that it is preferable in the trunk 110 to have elastic means 300 able to urge the elements 200 stacked against the bottom wall 114.

Selon le mode de réalisation non revendiqué illustré sur les figures 1 à 4, les éléments déployables 200 sont formés de lames allongées dans une direction orthogonale à la direction de déplacement des éléments 200 dans le guide 150.According to the unclaimed embodiment illustrated on the Figures 1 to 4 , the deployable elements 200 are formed of elongate blades in a direction orthogonal to the direction of movement of the elements 200 in the guide 150.

Néanmoins, on décrira par la suite, en regard des figures 12 et suivantes, une variante de réalisation selon laquelle les éléments 200 ont une extension limitée transversalement à la direction du guide 150 et possède au contraire une extension importante dans la direction de ce guide 150 pour former des structures de type antenne. Les caractéristiques des modes de réalisation correspondant à ces figures 12 et suivantes ne sont, pourtant, pas limitées à ce type de structure et peuvent, également, trouver une application dans les volets roulants ou autres dispositifs d'occultation, moyennant des aménagements appropriés susceptibles d'être apportés par l'homme du métier.Nevertheless, it will be described later, with regard to figures 12 and following, an alternative embodiment in which the elements 200 have an extension limited transversely to the direction of the guide 150 and on the contrary has a significant extension in the direction of this guide 150 to form antenna type structures. The features of the embodiments corresponding to these figures 12 et al. are, however, not limited to this type of structure and may, also, find an application in the shutters or other devices occultation, with appropriate arrangements that can be made by the skilled person.

On a illustré sur la figure 2 une vue latérale d'un tel élément 200 selon une vue orthogonale à sa direction de déplacement dans le guide 150.We illustrated on the figure 2 a side view of such an element 200 according to a view orthogonal to its direction of movement in the guide 150.

De préférence tous les éléments 200 composant une mme structure sont identiques. Cependant on peut envisager d'associer dans une même structure des éléments 200 différents, notamment quant à leurs dimensions et leurs fonctions.Preferably all the elements 200 composing the same structure are identical. However, it is conceivable to combine in the same structure 200 different elements, especially as to their dimensions and their functions.

Par ailleurs l'élément 200 le plus avant, dans le sens du déploiement, dans le guide 150 peut être différent des autres éléments 200 et constituer une pièce d'habillage, au moins du fait qu'il ne requiert des moyens d'accrochage mutuel avec un autre élément, que sur sa tranche aval.Furthermore, the element 200 furthest forward, in the direction of deployment, in the guide 150 may be different from the other elements 200 and may constitute a covering part, at least since it does not require means for mutual engagement. with another element, only on its downstream edge.

Pour la réalisation de volets d'occultation, les éléments 200 sont formés de cloisons pleines et opaques. Cette disposition n'est cependant pas nécessaire pour toutes applications. On peut ainsi envisager dans le cadre de la présente invention de réaliser l'essentiel du corps des éléments 200 à l'aide de panneaux largement ajourés.For the realization of shutters of occultation, the elements 200 are formed of solid and opaque partitions. This arrangement is however not necessary for all applications. In the context of the present invention, it is thus possible to envisage making most of the body of the elements 200 using widely openwork panels.

Selon le mode de réalisation non revendiqué illustré sur les figures 1 à 4, chaque élément 200 possède un corps central 210 délimité essentiellement par deux faces principales 212,214 planes et parallèles entre elles.According to the unclaimed embodiment illustrated on the Figures 1 to 4 each element 200 has a central body 210 defined essentially by two main faces 212,214 planar and parallel to each other.

Chaque élément 200 possède au niveau de chacune de ses tranches perpendiculaires à la direction de déplacement dans le guide 150, des moyens d'accrochage 220. Ces moyens 220 sont destinés à assurer un accrochage mutuel de chaque paire de deux éléments 200 lorsque ceux-ci sont disposés à l'extérieur du coffre 110.Each element 200 has at each of its slices perpendicular to the direction of movement in the guide 150, fastening means 220. These means 220 are intended to ensure mutual engagement of each pair of two elements 200 when they are arranged outside the box 110.

De tels moyens d'accrochage 220 peuvent faire l'objet de nombreux modes de réalisation.Such attachment means 220 may be the subject of many embodiments.

Ils peuvent être continus sur toute la longueur des lames 200 ou seulement partiels, limités à une partie de la longueur des lames 200.They can be continuous along the entire length of the blades 200 or only partial, limited to a part of the length of the blades 200.

De préférence les moyens d'accrochage 220 définissent deux rainures 222,224 qui débouchent respectivement sur des faces opposées 212,214 des éléments 200.Preferably the attachment means 220 define two grooves 222, 244 which open respectively to opposite faces 212, 214 of the elements 200.

Plus précisément la rainure aval 222 (c'est à dire celle qui pénètre en premier dans le coffre 110) débouche sur la face 212 des lames 200 dirigées à l'opposée du pan incliné 116. Au contraire la rainure amont 224 (c'est à dire celle qui pénètre en dernier dans le coffre 110) débouche sur la face 214 des lames 200 dirigée vers le pan incliné 116.More specifically, the downstream groove 222 (that is to say the one that first enters the trunk 110) opens on the face 212 of the blades 200 directed to the opposite of the inclined face 116. On the contrary, the upstream groove 224 (that is to say the one which enters last in the chest 110) opens on the face 214 of the blades 200 directed towards the inclined face 116.

Avantageusement ces rainures 222,224 sont symétriques entre elles.Advantageously these grooves 222,224 are symmetrical to each other.

Selon le mode de réalisation particulier non revendiqué illustré sur les figures 1 à 4, chaque élément 200 comporte un tronçon 230 intermédiaire entre le corps central 210 à faces parallèles et les rainures 222,224.According to the particular unclaimed embodiment illustrated on the Figures 1 to 4 each element 200 comprises an intermediate section 230 between the central body 210 with parallel faces and the grooves 222, 244.

Chaque tronçon intermédiaire 230 est délimité d'une part par une facette 232 plane qui prolonge l'une des faces principales 212, respectivement 214 du corps 210, et un pan oblique 234. Ce dernier diverge par rapport à la face 212,214 sur laquelle débouche la rainure 222,224 en rapprochement de celle-ci.Each intermediate section 230 is delimited on the one hand by a plane facet 232 which extends one of the main faces 212, 214 of the body 210, and an oblique face 234. The latter diverges with respect to the face 212, 214 on which the 222,224 groove in the vicinity thereof.

Les moyens d'accrochage constitués par les rainures 222, 224 définissent une liaison non parallèle à la direction longitudinale du guide 150, par exemple une liaison perpendiculaire ou oblique à cette direction.The attachment means constituted by the grooves 222, 224 define a non-parallel connection to the longitudinal direction of the guide 150, for example a perpendicular connection or oblique to this direction.

Selon le mode de réalisation non revendiqué illustré sur les figures 1 à 4, chaque rainure 222,224 possède une section droite globalement en U. Elle est délimitée sur l'extérieur (qui correspond à la tranche des lames 200) par un muret 226 dont la hauteur (considérée dans une direction orthogonale aux faces 212,214) est supérieure à la hauteur correspondante de la paroi 228 des rainures adjacentes aux pans obliques 234. Cette disposition a pour but de garantir d'une part que les murets 226 échappent à la paroi en regard 228 des lames respectivement associées, grâce au pan incliné 116, lors de l'empilage dans le coffre 110, et d'autre part de garantir que les murets 226 de deux lames adjacentes viennent au contraire en prise, lors du déploiement dans le guide 150.According to the unclaimed embodiment illustrated on the Figures 1 to 4 each groove 222,224 has a generally U-shaped cross section. It is delimited on the outside (which corresponds to the edge of the blades 200) by a wall 226 whose height (considered in a direction orthogonal to the faces 212,214) is greater than the corresponding height of the wall 228 of the grooves adjacent to the oblique faces 234. This provision is intended to ensure on the one hand that the walls 226 escape the facing wall 228 respectively associated blades, thanks to the inclined face 116, during the stacking in the trunk 110, and secondly to ensure that the walls 226 of two adjacent blades instead engage during deployment in the guide 150.

La largeur de chaque rainure 222,224, considérée parallèlement à la direction de déplacement des lames 200 dans le guide 150, est typiquement complémentaire de la largeur des murets 226 de sorte que en position déployée dans le guide 150 chaque muret 226 d'une lame 200 puisse pénétrer dans la rainure complémentaire 222,224 d'une lame adjacente, sans jeu dans la direction du guide 150 en dehors du jeu fonctionnel nécessaire pour l'engagement des murets 226 dans les rainures 222,224 et nécessaire au déplacement de l'ensemble des lames 200 dans le guide 150.The width of each groove 222,224, considered parallel to the direction of movement of the blades 200 in the guide 150, is typically complementary to the width of the walls 226 so that in the deployed position in the guide 150 each wall 226 of a blade 200 can penetrate into the complementary groove 222,224 of an adjacent blade, without play in the direction of the guide 150 apart from the functional clearance required for the engagement of the walls 226 in the grooves 222,224 and necessary for the displacement of the assembly of the blades 200 in the guide 150.

On obtient ainsi une liaison mécanique, sans jeu, entre les lames 200, que ce soit à la traction, dans le sens d'un déploiement des lames 200 dans le guide 150, ou au contraire dans le sens d'une compression, dans le sens d'un repliement des lames 200 dans le coffre 110. Cette dernière caractéristique permet d'une part une grande résistance contre les tentatives d'intrusion puisqu'elle interdit un repliement forcé des lames 200. Elle permet d'autre part un entraînement simple des lames 200 puisqu'elle permet d'agir sur l'une seulement et quelconque des lames 200 situées à l'extérieur du coffre 110 pour assurer le déploiement ou le repliement.This gives a mechanical connection, without play, between the blades 200, either by traction, in the direction of a deployment of the blades 200 in the guide 150, or on the contrary in the sense of a compression, in the direction of a folding of the blades 200 in the trunk 110. This last feature allows on the one hand a great resistance against intrusion attempts since it prohibits a forced folding blades 200. It also allows a simple drive 200 blades since it allows to act on any one and any of the blades 200 located outside the trunk 110 to ensure deployment or refolding.

De même typiquement la somme de la hauteur d'un muret 226 et de l'épaisseur de la paroi de fond de rainure 222,224 est égale à l'épaisseur des lames 200.Similarly typically the sum of the height of a wall 226 and the thickness of the groove bottom wall 222,224 is equal to the thickness of the blades 200.

Enfin on notera que de préférence, selon le mode de réalisation non revendiqué illustré sur les figures 1 à 4, chaque lame 200 possède un arrondi 229 sur son arête qui correspond à l'angle de la tranche opposé à la face sur laquelle débouchent les rainures 222,224.Finally, it will be noted that, preferably, according to the unclaimed embodiment illustrated on the Figures 1 to 4 each blade 200 has a rounding 229 on its edge which corresponds to the angle of the edge opposite the face on which the grooves 222,224 open.

Selon une autre caractéristique visible figures 22a, 22b, 23a, 23b, les lames 200 peuvent, encore, comporter au niveau desdits moyens d'accrochage 220, des moyens d'accrochage complémentaires 220A aptes à assurer une immobilisation entre deux éléments déployables adjacents 200, ceci dans un sens transversal à la direction du guide 150 et en position d'engagement des moyens d'accrochage 220.According to another visible characteristic FIGS. 22a, 22b, 23a, 23b , the blades 200 may further comprise at said attachment means 220, complementary attachment means 220A capable of ensuring immobilization between two adjacent deployable elements 200, this in a sense transverse to the direction of the guide 150 and in the engagement position of the attachment means 220.

De tels moyens d'accrochage complémentaires 220A sont prévus avec un certain jeu J autorisant leur désengagement et celui des moyens d'accrochage 220 lors du repliement des lames 200 de la structure dans le coffre 110.Such complementary attachment means 220A are provided with a certain clearance J allowing their disengagement and that of the attachment means 220 during the folding of the blades 200 of the structure in the trunk 110.

De tels moyens d'accrochage complémentaires 220A permettent, également, d'envisager leur activation (figures 22b, 23b) ou leur désactivation (figures 22a, 23a) en position déployée des éléments déployables 200, ceci en intervenant sur la position relative de ces éléments déployables 200 en évitant ou en assurant le jeu J.Such complementary attachment means 220A also make it possible to envisage their activation ( Figures 22b, 23b ) or their deactivation ( Figures 22a, 23a ) in the deployed position of the deployable elements 200, this intervening on the relative position of these deployable elements 200 avoiding or ensuring the game J.

Les lames 200 peuvent être formées de matériau plein possédant une section constante. Dans ce cas les lames 200 possèdent des structures de rainure 222,224 identiques à celles visibles sur la figure 2, sur toute leur longueur. En variante cependant les structures de rainure 222,224 peuvent être limitées à une partie de la longueur des lames 200. Dans ce cas des structures de rainure 222,224 sont alors prévues de préférence au voisinage de chacune des extrémités des lames 200 destinées à coopérer avec les guides 150.The blades 200 may be formed of solid material having a constant section. In this case the blades 200 have groove structures 222,224 identical to those visible on the figure 2 , over their entire length. Alternatively, however, the groove structures 222, 244 may be limited to a portion of the length of the blades 200. In this case groove structures 222, 244 are then preferably provided adjacent each of the ends of the blades 200 intended to cooperate with the guides 150. .

Les lames 200 peuvent être formées d'élément massif monobloc.The blades 200 may be formed of solid monoblock element.

Cependant les lames 200 peuvent être formées par assemblage de différents composants.However, the blades 200 can be formed by assembling different components.

Il peut s'agir par exemple de l'assemblage d'un corps central 240, par exemple un corps réalisé par extrusion, et de deux embouts 242,244, sur les extrémités de celui-ci (du type illustré figures 7 et 11). Dans ce cas les moyens formant les rainures 222,224 peuvent être prévus soit sur le corps central 240 soit sur les embouts 242,244.It may be for example the assembly of a central body 240, for example a body made by extrusion, and two end pieces 242, 244, on the ends thereof (of the illustrated type). figures 7 and 11 ). In this case the means forming the grooves 222,224 can be provided either on the central body 240 or on the end pieces 242,244.

On peut ainsi réaliser le corps par extrusion avec plusieurs parois et alvéoles pour lui conférer une résistance à la flexion importante.It is thus possible to make the body by extrusion with several walls and cavities to give it a high resistance to bending.

Il peut s'agir par exemple d'un corps central 240 formé par assemblage de deux panneaux latéraux sur des longerons définissant les structures de rainure 222, 224 avec interposition d'une lame d'air, voire d'un matériau présentant de bonnes propriétés d'isolation phonique et/ou thermique, entre les deux panneaux.It may be for example a central body 240 formed by assembling two side panels on longitudinal members defining the groove structures 222, 224 with the interposition of an air knife, or even a material having good acoustic and / or thermal insulation properties, between the two panels.

Elles peuvent être formées de tout matériau approprié, notamment en matière plastique et/ou en métal, par exemple en aluminium.They may be formed of any suitable material, in particular plastic and / or metal, for example aluminum.

Les moyens d'entraînement des lames 200 peuvent faire l'objet de nombreux modes de réalisation. Il peut s'agir de moyens d'entraînement manuels ou motorisés. Ces moyens d'entraînement sont adaptés pour venir en prise avec l'une au moins des lames 200 en sortie du coffre 110 pour imposer à celle-ci un déplacement dans le guide 150, alternativement dans le sens d'un déploiement dans le guide 150 ou au contraire dans le sens d'un empilement dans le coffre 110.The drive means of the blades 200 may be the subject of many embodiments. It can be manual or motorized drive means. These drive means are adapted to engage at least one of the blades 200 at the outlet of the box 110 to impose on it a displacement in the guide 150, alternately in the direction of deployment in the guide 150 or on the contrary in the sense of a stack in the trunk 110.

En effet grâce à la structure proposée dans le cadre de la présente invention, qui impose une immobilisation relative entre les lames 200 à la sortie du coffre 110, il suffit d'entraîner l'une quelconque des lames 200 pour assurer simultanément l'entraînement de l'ensemble des lames.Indeed, thanks to the structure proposed in the context of the present invention, which imposes a relative immobilization between the blades 200 at the exit of the trunk 110, it suffices to drive any one of the blades 200 to simultaneously provide the drive. the set of blades.

En pratique les moyens d'entraînement peuvent comprendre un pignon entraîné à rotation autour de son axe fixe au niveau de la sortie du coffre 110 et apte à venir en prise (par l'intermédiaire d'une crémaillère prévue sur chaque lame 200) avec la lame 200 adjacente au fond du coffre 110. Dans ce cas on comprend que le pignon vient successivement en prise avec les différentes lames au fur et à mesure de leur avancement.In practice, the drive means may comprise a pinion driven to rotate about its fixed axis at the outlet of the box 110 and adapted to engage (via a rack provided on each blade 200) with the 200 blade adjacent to the bottom of the trunk 110. In this case it is understood that the pinion is successively engaged with the different blades as they progress.

Selon une autre variante les moyens d'entraînement peuvent être adaptés pour venir en prise avec la lame 200 la plus externe, c'est à dire la lame la plus avant dans le sens du déploiement, dans le guide 150.According to another variant, the drive means may be adapted to engage with the outermost blade 200, ie the blade that is furthest forward in the direction of deployment, in the guide 150.

Le fonctionnement du dispositif non revendiqué illustré sur les figures 1 à 4 annexées est essentiellement le suivant.The operation of the unclaimed device illustrated on the Figures 1 to 4 annexed is essentially the following.

La direction de translation des lames 200 dans le guide 150 est référencée T sur la figure 3.The direction of translation of the blades 200 in the guide 150 is referenced T on the figure 3 .

Le gerbage ou empilement des lames 200 dans le coffre 110 à partir de la position illustrée sur la figure 4a est réalisé comme suit.The stacking or stacking of the blades 200 in the trunk 110 from the position illustrated on the figure 4a is performed as follows.

Sur cette figure 4a, une lame LI est illustrée en position gerbée dans le coffre 110. La lame suivante L2 est en position longitudinale déployée, comme les lames suivantes L3, L4 et L5. La lame L2 est ainsi en prise par l'intermédiaire des moyens d'accrochage 226 avec les moyens complémentaires 222 de la lame L3. La lame L2 est placée dans une position intermédiaire entre le guide 150 et le fond du coffre 110.On this figure 4a , a blade LI is illustrated in the stacked position in the trunk 110. The next blade L2 is in extended longitudinal position, as the following blades L3, L4 and L5. The blade L2 is thus engaged via the attachment means 226 with the complementary means 222 of the blade L3. The blade L2 is placed in an intermediate position between the guide 150 and the bottom of the box 110.

La figure 4b montre que le déplacement longitudinal des lames 200, dans le sens de l'élongation du guide 150, associé à la présence du chanfrein 126, de l'arrondi 229 et du pan oblique 116 permet la rotation de la lame L2 lorsque celle-ci est sollicitée vers ce pan oblique 116 par le moyen de sollicitation 300.The figure 4b shows that the longitudinal displacement of the blades 200, in the direction of elongation of the guide 150, associated with the presence of the chamfer 126, the rounded 229 and the oblique pan 116 allows the rotation of the blade L2 when it is urged towards this oblique end 116 by the biasing means 300.

La figure 4c montre la lame L2 en appui contre le pan oblique 116. Son mouvement longitudinal est bloqué par la paroi 122 du coffre. Le pivotement de la lame L2 assure le désengagement de son moyen d'accrochage 224 et du moyen d'accrochage complémentaire 222 de la lame adjacente L3. On notera que lors de l'inversion du mouvement et donc du déploiement, les murets 226 au contraire viennent en prise pour permettre l'accrochage des lames.The figure 4c shows the blade L2 bears against the oblique pan 116. Its longitudinal movement is blocked by the wall 122 of the box. The pivoting of the blade L2 ensures the disengagement of its attachment means 224 and the complementary attachment means 222 of the adjacent blade L3. Note that during the inversion of the movement and therefore the deployment, the walls 226 on the contrary come into engagement to allow the attachment of the blades.

La figure 4d montre que le mouvement se poursuit par le soulèvement de la lame L2 par la lame L3 grâce au pan oblique 234, accompagné d'un mouvement relatif dans la direction de la glissière 152 entre les lames L2 et L3.The figure 4d shows that the movement continues by the lifting of the blade L2 by the blade L3 through the oblique pan 234, accompanied by a relative movement in the direction of the slide 152 between the blades L2 and L3.

La figure 4e montre la lame L3 prenant position sous la lame L2.The figure 4e shows the blade L3 taking position under the blade L2.

La figure 4f montre que la lame L3 a pris la position initiale de la lame L2. Un cycle complet de gerbage d'une lame 200 est ainsi achevé.The figure 4f shows that the blade L3 has taken the initial position of the blade L2. A complete stacking cycle of a blade 200 is thus completed.

Le dégerbage d'une lame 200 est opéré selon la cinématique inverse.The removal of a blade 200 is performed according to the reverse kinematics.

On remarquera que l'assemblage des lames 200 entre elles nécessite un déplacement relatif de leurs zones d'accrochage 222,224 (de deux lames différentes) dans une direction perpendiculaire au sens longitudinal du déplacement dans les glissières 150.Note that the assembly of the blades 200 between them requires a relative displacement of their attachment zones 222,224 (of two different blades) in a direction perpendicular to the longitudinal direction of movement in the slides 150.

La largeur du guide 150 étant complémentaire de l'épaisseur des lames 200 et la largeur des rainures 222,224 étant complémentaire de la largeur des murets 226, tout mouvement relatif entre les moyens d'accrochage 222/224/226 de deux éléments déployables adjacents 200, est interdit, lorsque ceux-ci sont positionnés en dehors du coffre 110, quel que soit le sens de déplacement des éléments déployables dans le guide.The width of the guide 150 being complementary to the thickness of the blades 200 and the width of the grooves 222,224 being complementary to the width of the walls 226, any relative movement between the attachment means 222/224/226 of two adjacent deployable elements 200, is prohibited, when they are positioned outside the trunk 110, regardless of the direction of movement of the expandable elements in the guide.

On va maintenant décrire le deuxième mode de réalisation illustré sur les figures 5 à 10 annexées et faisant parti de la présente inveniton.We will now describe the second embodiment illustrated on the Figures 5 to 10 annexed and forming part of this invention.

On retrouve sur celles-ci des moyens de guidage 100 et des éléments déployables 200.On these are guiding means 100 and deployable elements 200.

Les moyens constitutifs de ceux-ci identiques ou fonctionnellement équivalents aux moyens précédemment décrits en regard des figures 1 à 4 ne seront pas décrits dans le détail par la suite et porteront des références numériques identiques à celles utilisées sur les figures 1 à 4.The means constituting them identical or functionally equivalent to the means previously described with regard to the Figures 1 to 4 will not be described in detail later and will have identical reference numbers to those used on Figures 1 to 4 .

Le deuxième mode de réalisation illustré sur les figures 5 à 10 annexées, plus particulièrement conforme à l'invention, se distingue principalement de celui représenté sur les figures 1 à 4 par le fait que les éléments déployables 200 adoptent un mouvement de translation à l'intérieur du coffre 110, cette translation est due à des formes de guidage complémentaires prévues respectivement sur les flancs 120 du coffre 110 et sur les flancs en regard 250 des lames.The second embodiment illustrated on the Figures 5 to 10 annexed, more particularly in accordance with the invention, differs mainly from that shown in Figures 1 to 4 in that the deployable elements 200 adopt a translational movement inside the trunk 110, this translation is due to complementary guide shapes respectively provided on the sidewalls 120 of the trunk 110 and on the side flanks 250 of the blades.

Ces formes de guidage complémentaires sont agencées pour conférer aux éléments déployables 200, dans le coffre 110, un déplacement selon une direction présentant une composante transversale à la direction longitudinale du guide 150.These complementary guiding shapes are arranged to give the deployable elements 200, in the trunk 110, a displacement in a direction having a component transverse to the longitudinal direction of the guide 150.

En fait, de telles formes de guidage complémentaires sont, plus particulièrement, définies pour conférer auxdits éléments déployables 200 un mouvement de translation à l'intérieur du coffre 110, une telle translation comportant une composante selon une direction transversale à la direction longitudinale T du guide 150 (et par conséquent à la direction de déplacement des éléments déployables 200 dans ce guide 150).In fact, such complementary forms of guidance are, more particularly, defined to confer on said elements deployable 200 translational movement inside the trunk 110, such a translation having a component in a direction transverse to the longitudinal direction T of the guide 150 (and therefore the direction of movement of the deployable elements 200 in this guide 150) .

A ce propos, on observera que, de manière additionnelle, de telles formes de guidage peuvent, encore, tre définies pour conférer à un tel élément déployable 200, notamment lors de son entrée dans le coffre 110, un mouvement de translation comportant, outre une composante selon une direction transversale à la direction longitudinale T du guide 150, une composante selon cette direction longitudinale T du guide 150.In this respect, it will be observed that, in addition, such guiding forms may, again, be defined to give such a deployable element 200, in particular when it enters the trunk 110, a translational movement comprising, in addition to a component in a direction transverse to the longitudinal direction T of the guide 150, a component in this longitudinal direction T of the guide 150.

En fait, chaque flanc 120 du coffre 110 est muni d'au moins un guide 160, tel une nervure (figures 5 à 10) ou une rainure, susceptible de présenter une forme quelconque, adaptée pour conférer un mouvement sensiblement de translation selon une trajectoire définie à un élément déployable 200 destiné à être rangé, par empilement, à l'intérieur d'un coffre 110 ou à en être extrait.In fact, each sidewall 120 of the box 110 is provided with at least one guide 160, such as a rib ( Figures 5 to 10 ) or a groove, capable of having any shape, adapted to impart a substantially translational movement along a defined trajectory to a deployable element 200 intended to be stowed, by stacking, inside a trunk 110 or to be extract.

Ainsi, cette trajectoire conférée à un élément déployable 200 peut se décomposer en une succession de tronçons rectilignes et/ou curvilignes.Thus, this trajectory conferred on a deployable element 200 can be broken down into a succession of rectilinear and / or curvilinear sections.

Un mode de réalisation non limitatif de l'invention consiste en ce qu'une telle nervure est inclinée (voire perpendiculaire) par rapport à la direction longitudinale T du guide 150, voire encore rectiligne. Plus précisément et tel que visible sur les figures 5 à 10, chaque guide 160 diverge par rapport à la paroi de fond 114 du coffre 110, en éloignement du guide 150.A non-limiting embodiment of the invention consists in that such a rib is inclined (or even perpendicular) with respect to the longitudinal direction T of the guide 150, or even rectilinear. More precisely and as visible on the Figures 5 to 10 each guide 160 diverges relative to the bottom wall 114 of the box 110, away from the guide 150.

Un mode de réalisation particulier consiste en ce que les formes de guidage complémentaires sont obliques, par exemple à 45°, par rapport à la direction longitudinale T du guide 150.A particular embodiment consists in that the complementary guide shapes are oblique, for example at 45 °, with respect to the longitudinal direction T of the guide 150.

Plus précisément encore, selon le mode de réalisation illustré sur les figures 5 à 10, il est prévu au moins deux guides 160,162 sur chaque flanc 120 du coffre 110. Les guides 160,162 sont répartis longitudinalement sur les flancs 120, selon une répartition dans une direction parallèle à la direction d'élongation T des guides 150.More precisely still, according to the embodiment illustrated on the Figures 5 to 10 at least two guides 160,162 are provided on each side 120 of the box 110. The guides 160,162 are distributed longitudinally on the sidewalls 120, according to a distribution in a direction parallel to the direction of elongation T of the guides 150.

Les guides 160,162 sont, de préférence, parallèles entre eux.The guides 160, 162 are preferably parallel to each other.

Il est prévu par ailleurs des moyens assurant que lors de l'engagement des lames 200 dans le coffre 110, les guides 160, 162 viennent en prise avec des moyens complémentaires prévus sur les flancs 250 des lames.It is further provided means ensuring that during the engagement of the blades 200 in the trunk 110, the guides 160, 162 engage with complementary means provided on the sidewalls 250 of the blades.

Ainsi on notera que selon le mode de réalisation illustré sur les figures 5 à 10, les guides 160,162 ont leur extrémité la plus proche de la paroi de fond 114 située à des distances différentes de celle-ci. Le guide 160 le plus éloigné de la glissière 152 est plus proche de la paroi de fond 114 que le guide 162 le plus proche de la glissière 152.Thus, it will be noted that according to the embodiment illustrated on the Figures 5 to 10 the guides 160,162 have their ends closest to the bottom wall 114 at different distances therefrom. The guide 160 farthest from the slide 152 is closer to the bottom wall 114 than the guide 162 closest to the slide 152.

En revanche de préférence les extrémités des guides 160, 162 les plus éloignées de la paroi de fond 114 sont situées à des distances identiques de la paroi de fond 114.In contrast, preferably the ends of the guides 160, 162 farthest from the bottom wall 114 are located at identical distances from the bottom wall 114.

Les lames 200 sont munies sur chacun de leurs flancs 250 de gorges 252,254, complémentaires dans leurs orientations et dimensions des guides 160,162.The blades 200 are provided on each of their flanks 250 grooves 252,254, complementary in their orientations and dimensions of the guides 160,162.

On notera que pour permettre l'engagement respectivement de la gorge 252 sur le guide 160 et de la gorge 254 sur le guide 162, les entrées des gorges 252,254 qui débouchent sur la face 212 des lames 200 dirigée à l'opposée du fond 114 du coffre 110 sont situées à des altitudes différentes par rapport cette face 212. Plus précisément pour cela il est prévu sur les flancs 250 des lames 200 deux lumières longitudinales 253,255, parallèles à la face 212 et qui débouchent sur celle-ci. Les deux lumières ont des largeurs différentes. La lumière aval 253, en ce sens qu'elle est la plus proche de la paroi avale 122 du coffre 110, a la plus grande largeur. Elle débouche dans la gorge 252. Sa largeur est telle que l'épaisseur de toile restante sous la lumière 253 sur le flanc 250 soit complémentaire de la distance séparant le guide 160 et la paroi de fond 114 du coffre 110. La lumière 255 prolonge la lumière 253 précitée. Elle débouche dans la gorge 254. Sa largeur est telle que l'épaisseur de toile sous jacente restante sous la lumière 255 soit complémentaire de la distance séparant le guide 162 et la paroi de fond 114 du coffre 110.Note that to enable the engagement respectively of the groove 252 on the guide 160 and the groove 254 on the guide 162, the entries of the grooves 252,254 which open on the face 212 of the blades 200 directed to the opposite of the bottom 114 of the 110 are located at different altitudes relative to this face 212. More specifically for this it is provided on the sides 250 of the blades 200 two longitudinal slots 253,255, parallel to the face 212 and which open thereon. The two lights have different widths. The downstream light 253, in that it is closest to the downstream wall 122 of the trunk 110, has the greatest width. It opens into the groove 252. Its width is such that the thickness of fabric remaining under the light 253 on the sidewall 250 is complementary to the distance separating the guide 160 and the bottom wall 114 of the trunk 110. The light 255 prolongs the light 253 above. It opens into the throat 254. Its width is such that the thickness of the underlying fabric remaining under the light 255 is complementary to the distance separating the guide 162 and the bottom wall 114 of the box 110.

Les dispositions qui viennent d'être décrites permettent de garantir que les guides 160,162 viennent en appui contre le bord d'entrée des gorges 252,254 lorsque les lames 200 sont déplacées vers l'intérieur du coffre 110.The arrangements which have just been described make it possible to guarantee that the guides 160, 162 bear against the entry edge of the grooves 252, 254 when the blades 200 are moved towards the inside of the box 110.

En pratique, selon le mode de réalisation illustré sur les figures 5 à 10, les gorges 252,254 sont formées dans les embouts 242,244.In practice, according to the embodiment illustrated on the Figures 5 to 10 , the grooves 252, 254 are formed in the end pieces 242, 244.

Là encore il est prévu un moyen de sollicitation élastique 300 à l'intérieur du coffre 110.Again there is provided an elastic biasing means 300 inside the trunk 110.

On a décrit précédemment des formes de guidage en saillie sur les flancs du coffre 110 aptes à pénétrer dans des formes en creux complémentaires prévues sur les flancs 250 des lames. Bien entendu la disposition inverse peut être retenue. C'est à dire que les moyens de guidage prévus sur les flancs 120 du coffre 110 peuvent adopter une forme en creux (notamment en adoptant la forme d'une rainure ou analogue), tandis que les moyens complémentaires prévus sur les flancs des lames 200 seraient en saillie. A ce propos, on observera que de tels moyens en saillie peuvent se présenter sous la forme de galets, tétons ou analogue, chacun de longueur et/ou de section adaptée pour venir se déplacer dans une rainure ou analogue de profondeur et/ou de largeur correspondante. Un tel mode de réalisation permet, par exemple, d'affecter un élément en saillie spécifique à un élément en creux spécifique pour un guidage approprié.We have previously described guiding shapes protruding on the sides of the trunk 110 able to penetrate into complementary recessed shapes provided on the sidewalls 250 of the blades. Of course the opposite arrangement can be retained. That is to say that the guide means provided on the sidewalls 120 of the box 110 may adopt a hollow shape (in particular by adopting the shape of a groove or the like), while the complementary means provided on the sides of the blades 200 would be protruding. In this regard, it will be observed that such projecting means may be in the form of rollers, pins or the like, each of length and / or section adapted to move in a groove or the like of depth and / or width corresponding. Such an embodiment makes it possible, for example, to assign a specific protruding element to a specific recessed element for appropriate guidance.

Là encore, de tels moyens de guidage peuvent présenter une forme quelconque, adaptée pour conférer un mouvement sensiblement de translation selon une trajectoire définie à un élément déployable 200 destiné à être rangé, par empilement, à l'intérieur d'un coffre 110 ou à en être extrait.Again, such guiding means may have any shape adapted to impart a substantially translational movement along a defined path to a deployable member 200 to be stacked inside a trunk 110 or to be extracted.

Les figures 9 et 10 représentent de manière comparable à la figure 4 les étapes principales d'empilage/déploiement de lames 200.The figures 9 and 10 represent in a comparable way to the figure 4 the main steps of stacking / deploying blades 200.

La lame conforme au troisième mode de réalisation, illustrée sur la figure 11, se distingue de la lame 200 illustrée sur les figures 5 à 10 par le fait que les moyens d'accrochage 220, définis par des murets 226 et des rainures 222,224 associées, ne sont plus orthogonaux aux faces principales 212 et 214 des lames mais sont inclinés par rapport à celles-ci, par exemple à 45°.The blade according to the third embodiment, illustrated on the figure 11 , is distinguished from the blade 200 illustrated on the Figures 5 to 10 in that the attachment means 220, defined by walls 226 and associated grooves 222,224, are no longer orthogonal to the main faces 212 and 214 of the blades but are inclined with respect thereto, for example at 45 °.

De préférence la tranche aval des lames 200 (c'est à dire celle qui pénètre en premier dans le coffre 110) diverge par rapport à la paroi de fond 114 du coffre 110 en rapprochement de la glissière 152. De même la tranche amont des lames 200 (c'est à dire celle qui pénètre en dernier dans le coffre 110) diverge par rapport à la paroi de fond 114 du coffre 110 en rapprochement de la glissière 152.Preferably the downstream slice of the blades 200 (that is to say the one which first enters the trunk 110) diverges with respect to the bottom wall 114 of the trunk 110 towards the slideway 152. Similarly, the upstream edge of the blades 200 (that is to say the one that enters last in the trunk 110) diverges with respect to the bottom wall 114 of the trunk 110 towards the slideway 152.

Grâce à cette disposition, lors du déplacement des lames 200 dans le coffre 110, les efforts exercés entre les tranches de deux lames 200 participent au transfert des lames vers le volume interne du coffre 110 grâce à la composante transversale à la direction du guide 150 résultant du contact entre ces tranches inclinées.With this arrangement, during the displacement of the blades 200 in the trunk 110, the forces exerted between the slices of two blades 200 participate in the transfer of the blades to the internal volume of the trunk 110 through the transverse component to the direction of the guide 150 resulting contact between these inclined slices.

Une autre caractéristique concerne le fait que les lames 200 illustrées figures 5 à 11 peuvent, encore, comporter au niveau des moyens d'accrochage 220, des moyens d'accrochage complémentaires 220A (tels que visibles figures 22a, 22b, 23a et 23b) aptes à assurer une immobilisation entre deux éléments déployables adjacents 200, ceci dans un sens transversal à la direction du guide 150 et en position d'engagement des moyens d'accrochage 220.Another feature is that the illustrated blades 200 Figures 5 to 11 may also comprise, at the level of the attachment means 220, complementary fastening means 220A (as visible Figures 22a, 22b, 23a and 23b ) capable of ensuring immobilization between two adjacent deployable elements 200, in a direction transverse to the direction of the guide 150 and in the engagement position of the attachment means 220.

On va maintenant décrire le quatrième mode de réalisation conforme à la présente invention illustré sur les figures 12 et suivantes.The fourth embodiment according to the present invention will now be described figures 12 and following.

On retrouve sur celles-ci des moyens de guidage 100 et des éléments déployables 200.On these are guiding means 100 and deployable elements 200.

Les moyens constitutifs de ceux-ci identiques ou fonctionnellement équivalents aux moyens précédemment décrits en regard des figures 1 à 11 ne seront pas décrits dans le détail par la suite et porteront des références numériques identiques à celles utilisées sur les figures 1 à 11.The means constituting them identical or functionally equivalent to the means previously described with regard to the Figures 1 to 11 will not be described in the details and will have identical reference numbers to those used on Figures 1 to 11 .

En premier lieu on notera que, selon les figures 12 et suivantes, le déplacement transversal de lames 200 vers le volume interne du coffre 110 est assuré à l'aide de guides 160, 162 solidaires des flancs 120 de coffre de manière comparable aux figures 5 à 11. Cependant, selon les figures 12 et suivantes, ces guides 160,162 ne sont pas formés de nervures continues, mais seulement de pions équivalents.In the first place it will be noted that, according to figures 12 and following, the transverse displacement of blades 200 to the internal volume of the trunk 110 is provided by means of guides 160, 162 secured to the trunk sides 120 in a manner comparable to the Figures 5 to 11 . However, according to figures 12 and following, these guides 160,162 are not formed of continuous ribs, but only equivalent pions.

Par ailleurs selon la variante illustrée sur la figure 12, ces pions 160,162 et les ouvertures de gorges associées 252, 254 ne sont pas étagés par rapport à la paroi de base 114 du coffre 110. Ainsi pour initier le mouvement transversal des lames 200 vers le volume interne du coffre et assurer l'engagement des pions 160,162 dans les gorges 252,254, le coffre possède dans sa zone de jonction entre la paroi de base 114 et la paroi transversale 122, un pan incliné 123 oblique par rapport à la direction longitudinale du guide 150. Ce pan incliné 123 diverge par rapport à la paroi de base 114 en éloignement du guide 150. Ainsi lorsqu'une lame 200 est déplacée vers l'intérieur du coffre 110 et qu'elle atteint ce pan incliné 123, elle est soulevée et écartée de la paroi de base 114, de sorte que les pions 160,162 sont engagés dans les gorges 252,254.Moreover, according to the variant illustrated on the figure 12 these pins 160,162 and the associated groove openings 252, 254 are not staggered relative to the base wall 114 of the trunk 110. Thus to initiate the transverse movement of the blades 200 to the internal volume of the trunk and ensure the engagement of the In the grooves 252, 254, the chest has in its junction zone between the base wall 114 and the transverse wall 122, an inclined face 123 oblique with respect to the longitudinal direction of the guide 150. This inclined face 123 diverges with respect to the base wall 114 away from the guide 150. Thus when a blade 200 is moved towards the inside of the trunk 110 and reaches the inclined face 123, it is raised and removed from the base wall 114, so that that the pins 160,162 are engaged in the grooves 252,254.

Selon le mode de réalisation illustré sur les figures 12 et suivantes, on notera par ailleurs que les lames 200 sont guidées à la fois au niveau de la paroi de fond du coffre 110 et au niveau du guide 150 par des galets 102.According to the embodiment illustrated on the figures 12 and following, note that the blades 200 are guided both at the level of the bottom wall of the box 110 and at the level of the guide 150 by rollers 102.

On notera également que sur la figure 12 les moyens d'accrochage 220 sont formés d'un doigt 226 en saillie sur une extrémité des lames 200 selon une orientation inclinée par rapport aux faces 212,214 des lames, lequel doigt 226 est adapté d'une part pour venir en prise avec un barreau transversal 226bis prévu sur la seconde extrémité de la lame adjacente afin d'assurer une liaison mécanique entre les lames dans le sens longitudinal de la glissière 152, et est adapté d'autre part pour pénétrer dans un logement complémentaire 222 formé entre deux joues 223, sur la même seconde extrémité des lames afin d'assurer simultanément une liaison mécanique entre les lames dans un sens transversal à la fois à la direction longitudinale-de la glissière et transversal à la direction d'engagement des moyens d'accrochage 220.It will also be noted that on the figure 12 the attachment means 220 are formed of a finger 226 projecting from one end of the blades 200 in an inclined orientation with respect to the faces 212, 214 of the blades, which finger 226 is adapted on the one hand to engage with a transverse bar 226bis provided on the second end of the adjacent blade to ensure a mechanical connection between the blades in the longitudinal direction of the slide 152, and is adapted on the other hand to enter a complementary housing 222 formed between two cheeks 223, on the same second end of the blades to simultaneously provide a mechanical connection between the blades in a direction transverse to both the longitudinal direction of the slide and transverse to the engagement direction of the attachment means 220.

En variante selon les figures 13 et suivantes, la liaison entre les lames adjacentes 200 d'une part dans le sens longitudinal de la glissière 152, et d'autre part dans un sens transversal à la fois à la direction longitudinale de la glissière et transversal à la direction d'engagement des moyens d'accrochage 220 est assurée grâce à des structures complémentaires du type assemblage en queue d'aronde ou équivalent prévues respectivement sur les extrémités opposées des lames 200 (l'une des extrémités de chaque lame est équipée d'un élément mâle en saillie 2200 présentant une section droite en T s'appuyant sur des génératrices inclinées par rapport à la direction de déplacement des lames, tandis que l'autre extrémité de chaque lame 200 est munie d'une rainure femelle de section complémentaire 2202.Alternatively according to the figures 13 and following, the connection between the adjacent blades 200 on the one hand in the longitudinal direction of the slideway 152, and secondly in a direction transverse both to the longitudinal direction of the slideway and transverse to the direction of engagement fastening means 220 is provided by means of complementary structures of the dovetail assembly type or equivalent respectively provided on the opposite ends of the blades 200 (one end of each blade is equipped with a male protruding element 2200 having a T-shaped cross section supported on generatrices inclined relative to the direction of movement of the blades, while the other end of each blade 200 is provided with a female groove of complementary section 2202.

De plus, selon les modes de réalisation illustrés sur les figures 12 et suivantes, les moyens interdisant tout mouvement relatif entre les moyens d'accrochage 220 de deux éléments déployables adjacents 200 lorsque ceux-ci sont positionnés en dehors du coffre 110, quel que soit le sens de déplacement des éléments déployables 200 dans le guide 150, ne sont plus formés par le guide 150 lui-même, comme cela était le cas pour les modes de réalisation précédemment décrits.Moreover, according to the embodiments illustrated on the figures 12 and following, the means prohibiting any relative movement between the attachment means 220 of two adjacent deployable elements 200 when they are positioned outside the trunk 110, regardless of the direction of movement of the deployable elements 200 in the guide 150, are no longer formed by the guide 150 itself, as was the case for the previously described embodiments.

Selon les figures 12 et suivantes, ces moyens sont formés de verrous 260.According to figures 12 and following, these means are formed of locks 260.

Ces verrous 260 peuvent faire l'objet de nombreux modes de réalisation. Pour l'essentiel ils sont formés de moyens adaptés pour être déplacés entre une position de libération et une position de verrouillage. En position escamotée, les verrous 260 n'interfèrent pas avec les moyens d'accrochage 220 et permettent donc un libre engagement des murets 226 dans les rainures 222,224 ou tous moyens d'accrochage équivalents et respectivement une libre séparation de ceux-ci. Au contraire en position de verrouillage, les verrous 260 interfèrent avec les moyens d'accrochage 220 pour interdire une libre séparation de ceux-ci.These locks 260 may be the subject of many embodiments. Essentially they are formed of means adapted to be moved between a release position and a locking position. In the retracted position, the locks 260 do not interfere with the attachment means 220 and thus allow free engagement of the walls 226 in the grooves 222,224 or any equivalent attachment means and respectively a free separation thereof. In contrast in the locking position, the locks 260 interfere with the attachment means 220 to prohibit free separation thereof.

De préférence cette disposition s'applique aux cas ou, comme illustré sur les figures 12 et suivantes, les moyens d'accrochage 220 comprennent des structures dont l'orientation n'est pas orthogonale aux faces principales 212,214 des lames. Ainsi les verrous 260 peuvent être formés de tourillons 262 montés à coulissement sur une extrémité des lames 200 dans une direction perpendiculaire à la direction d'engagement réciproque de moyens d'accrochage 220. Les tourillons 262 sont sollicités élastiquement vers une position en saillie dans laquelle les tourillons 262 interfèrent avec le trajet d'engagement des moyens d'accrochage. Cependant les tourillons 262 sont solidaires de galets 264 ou tout autre moyen équivalent apte à être sollicité lors de l'entrée dans le coffre 110 pour escamoter l'élément de sollicitation élastique et le tourillon associé 262.Preferably this provision applies to cases where, as illustrated in figures 12 and following, the attachment means 220 comprise structures whose orientation is not orthogonal to the main faces 212,214 of the blades. Thus the latches 260 may be formed of journals 262 slidably mounted on one end of the blades 200 in a direction perpendicular to the reciprocal engagement direction of fastening means 220. The journals 262 are resiliently biased to a projecting position in which the journals 262 interfere with the engagement path of the fastening means. However, the journals 262 are secured to rollers 264 or any other equivalent means capable of being biased upon entry into the trunk 110 to retract the elastic biasing element and the associated journal 262.

Selon la figure 12 les galets 264 sont sollicités en position escamotée par une roue 104 prévue au niveau du contour d'ouverture du coffre 110, c'est à dire au niveau de la zone de jonction entre le coffre 110 et le guide 150.According to figure 12 the rollers 264 are biased in the retracted position by a wheel 104 provided at the opening contour of the box 110, that is to say at the junction zone between the box 110 and the guide 150.

Selon la variante illustrée sur les figures 13 et suivantes les galets 264 sont sollicités en position escamotée par une cloison 106 prévue au niveau du contour d'ouverture du coffre 110, parallèlement à la direction d'élongation du guide 150, avec des chanfreins d'entrée 107 et de sortie 108 facilitant le passage des galets 264 sous la cloison 106.According to the variant illustrated on the figures 13 and following the rollers 264 are biased in the retracted position by a partition 106 provided at the opening contour of the trunk 110, parallel to the direction of elongation of the guide 150, with chamfer input 107 and exit 108 facilitating the passage of the rollers 264 under the partition 106.

De préférence chaque lame 200 est munie à son extrémité opposée à celle portant le verrou 260 d'un logement 261 complémentaire d'une partie du tourillon 262.Preferably each blade 200 is provided at its end opposite to that carrying the lock 260 of a housing 261 complementary to a portion of the trunnion 262.

Le fonctionnement du dispositif reste globalement identique aux dispositions précédemment décrites.The operation of the device remains globally identical to the previously described arrangements.

Le dispositif conforme à la présente invention offre de nombreux avantages par rapport aux dispositions connues de la technique antérieure.The device according to the present invention offers many advantages over the known provisions of the prior art.

La présente invention permet notamment un encombrement global limité du fait qu'elle permet de limiter le volume du coffre 110 au volume total des lames 200.The present invention makes it possible in particular a limited overall bulk because it makes it possible to limit the volume of the box 110 to the total volume of the blades 200.

La présente invention permet une épaisseur significative des lames. Elle permet ainsi notamment d'intégrer toute fonction souhaitable dans l'épaisseur des lames, par exemple de donner à celles-ci une fonction vitrine ou encore de leur intégrer des moyens actifs anti-intrusion. Elle permet également de réaliser aisément toute isolation phonique et/ou thermique recherchée et offre une grande résistance contre les tentatives d'intrusion.The present invention allows a significant thickness of the blades. It thus makes it possible, in particular, to integrate any desirable function into the thickness of the blades, for example to give them a showcase function or to integrate them with active anti-intrusion means. It also makes it easy to achieve any sound and / or thermal insulation sought and offers great resistance against intrusion attempts.

La présente invention permet une bonne cohésion en traction (sens du déploiement) et en compression (sens du repliement) entre les lames 200.The present invention allows a good cohesion in traction (direction of deployment) and in compression (refolding direction) between the blades 200.

La présente invention offre une grande simplicité de fonctionnement (absence de câble, chaîne ou contre-poids).The present invention provides a great simplicity of operation (absence of cable, chain or counterweight).

Elle permet de plus une fonctionnalité dans toutes les directions, c'est à dire qu'elle permet un déploiement des lames°200 dans toutes directions.It also allows a functionality in all directions, ie it allows a deployment of ° 200 blades in all directions.

Bien entendu la présente invention n'est pas limitée aux modes de réalisation particuliers qui viennent d'être décrits, mais s'étend à toutes variantes de réalisation conformes à son esprit.Of course, the present invention is not limited to the particular embodiments which have just been described, but extends to all embodiments that are in keeping with its spirit.

En particulier, la présente invention n'est pas limitée quant à ses applications. Elle englobe notamment la réalisation de volets du type volets roulants. Cependant elle n'est aucunement limitée à cette application. La présente invention peut ainsi s'appliquer à toute structure déployable dans une direction verticale, horizontale, voire inclinée à la fois sur la verticale et sur l'horizontale, à toute structure ou paroi de grande dimension devant être stockée dans un volume restreint, et ainsi notamment à la réalisation de mats télescopiques, cloisons escamotables, planchers mobiles, fermetures, baies, etc...In particular, the present invention is not limited as to its applications. It includes in particular the realization of shutters type shutters. However, it is not limited to this application. The present invention can thus be applied to any structure deployable in a vertical direction, horizontal, or even inclined both vertically and horizontally, to any large structure or wall to be stored in a restricted volume, and thus notably to the realization of mats telescopic, retractable partitions, mobile floors, closures, windows, etc.

Encore une application envisageable concerne celle d'une structure déployable constituant, sous sa forme déployée, un rail de sécurité défini par une pluralité d'éléments déployables aboutés, un tel rail de sécurité pouvant être déployé et replié de manière continue.Yet another possible application relates to that of a deployable structure constituting, in its deployed form, a safety rail defined by a plurality of buttable deployable elements, such a safety rail can be deployed and folded continuously.

Finalement, l'invention peut encore concerner une structure complexe résultant de la juxtaposition ou de l'agencement d'au moins deux structures déployables du type susmentionné. Ainsi, un exemple de réalisation peut se présenter sous la forme de deux structures du type susmentionné et juxtaposées en sorte que les éléments déployables de ces structures puissent adopter un mouvement rectiligne et parallèle entre eux, une partie au moins des éléments déployables de l'une des structures étant raccordée, notamment par l'intermédiaire de moyens de liaison rigides ou semi-rigides, à une partie au moins des éléments déployables de l'autre structure.Finally, the invention can also relate to a complex structure resulting from the juxtaposition or the arrangement of at least two deployable structures of the aforementioned type. Thus, an exemplary embodiment may be in the form of two structures of the aforementioned type and juxtaposed so that the deployable elements of these structures can adopt a rectilinear movement and parallel to each other, at least a part of the deployable elements of one structures being connected, in particular via rigid or semi-rigid connection means, to at least part of the deployable elements of the other structure.

Par ailleurs les variantes illustrées sur les figures annexées, et précédemment décrites, peuvent être complétées par toutes structures adaptées de galets prévus sur les lames 200 et/ou sur les moyens de guidage 100 pour faciliter le guidage et le déplacement des lames 200, au niveau de toutes surfaces en regard et susceptibles de déplacement relatif, par exemple au niveau des pions 160,162.Furthermore, the variants illustrated in the appended figures, and previously described, may be supplemented by any suitable structures of rollers provided on the blades 200 and / or on the guide means 100 to facilitate the guiding and the displacement of the blades 200, of all facing surfaces and capable of relative movement, for example at the level of the pins 160,162.
