Abstract

The invention relates to an adjustable shading device defining a blind (1) comprising longitudinal parallel slats (11) mounted such as to pivot about individual longitudinal axles (15) between a closed configuration, in which the slats are in contact with one another, and an open configuration, in which the slats are not in contact with one another, thereby forming an open-worked blind. The shading device comprises rotation means (21, 22, 23, 24) for simultaneously rotating the individual axles (15), such that all of the slats (11) always occupy the same mutual orientation. In addition, the shading device comprises pulling means (31, 34, 37) for gathering the slats (11) together at one end of the blind (1) by moving the individual axles (15) closer to one another while the slats (11) are in the open configuration. Each slat (11) comprises longitudinal hooking means (12, 13) for hooking the slats to one another in the closed configuration. The device is characterised in that the individual axles (15) of the slats (11) can be moved in relation to one another along a locking path in the closed configuration in order to lock the longitudinal hooking means (12, 13) such that they are engaged with one another.

Description

Brise-soleil orientable  Swiveling sunshade
La présente invention concerne un brise-soleil orientable définissant un rideau comprenant des lames longitudinales parallèles, chaque lame étant montée pivotante autour d'un axe propre longitudinal entre une configuration fermée dans laquelle les lames sont jointives et s'étendent sensiblement dans un même plan et une configuration ouverte dans laquelle les lames sont hors de contact les unes des autres pour former un rideau ajouré, le brise-soleil comprenant des moyens de rotation pour faire tourner simultanément les axes propres de sorte que les lames ont toujours la même orientation mutuelle, le brise-soleil comprenant en outre des moyens de traction pour accumuler les lames d'un côté du rideau en rapprochant leurs axes propres, alors que les lames sont dans une configuration ouverte. The present invention relates to an adjustable sunshade defining a curtain comprising parallel longitudinal blades, each blade being pivotally mounted about a longitudinal axis between a closed configuration in which the blades are contiguous and extend substantially in the same plane and an open configuration in which the blades are out of contact with each other to form a perforated curtain, the sunshade comprising rotation means for simultaneously rotating the clean axes so that the blades always have the same mutual orientation, the sunshade further comprising traction means for accumulating the blades on one side of the curtain by bringing their own axes, while the blades are in an open configuration.
En général, les moyens de traction comprennent un moteur qui fait tourner un arbre sur lequel est montée une roue associée à une chaîne ou un câble. L'extrémité de la chaîne ou du câble est fixée avec l'axe propre de la lame inférieure qui constitue le bas du rideau. En actionnant le moteur, la chaîne ou la câble est enroulé(e) sur la roue, entraînant ainsi la lame inférieure. Lorsque celle-ci vient en contact de la lame située juste au-dessus d'elle, elle l'entraîne à son tour. Le moteur tourne jusqu'à ce que toutes les lames soient accumulées en haut du rideau, les lames étant successivement entraînées par les lames inférieures poussées par la lame la plus inférieure en prise avec la chaîne ou le câble de la roue. Dans ce système classique, les lames sont entraînées à tour de rôle à mesure que la lame inférieure monte. On peut également dire que les axes propres des lames se rapprochent successivement en commençant par le bas du rideau. Une autre façon de décrire ce système est de dire que les lames sont successivement cueillies par la lame inférieure adjacente qui est déplacée soit par la lame la plus inférieure, soit par un empilement de lames entraînées par la lame inférieure. Il s'agit là du système de relevage de rideau que l'on trouve dans les stores vénitiens. Bien entendu, ce système de relevage est dépendant de la gravité, car l'abaissement du rideau se fait par le propre poids des lames. In general, the traction means comprise a motor which rotates a shaft on which is mounted a wheel associated with a chain or a cable. The end of the chain or cable is fixed with the own axis of the lower blade which constitutes the bottom of the curtain. By operating the motor, the chain or cable is wound on the wheel, thus driving the lower blade. When it comes into contact with the blade just above her, she drives it in turn. The motor rotates until all the blades are accumulated at the top of the curtain, the blades being successively driven by the lower blades pushed by the lower blade engaged with the chain or the cable of the wheel. In this conventional system, the blades are driven in turn as the lower blade mounts. It can also be said that the clean axes of the blades approach successively starting from the bottom of the curtain. Another way of describing this system is to say that the blades are successively picked by the adjacent lower blade which is moved either by the lower blade or by a stack of blades driven by the lower blade. This is the curtain lift system found in Venetian blinds. Of course, this lifting system is dependent on gravity, because the lowering of the curtain is done by the own weight of the blades.
D'autre part, il est également connu que les moyens de rotation comprennent un moteur, qui est souvent le même que pour les moyens de traction, pour faire tourner les axes propres des lames sur eux-mêmes entre des positions d'inclinaison extrêmes. Lorsque les lames sont verticales, le rideau est fermé, les lames étant jointives. A partir de cette configuration fermée, il est possible d'incliner les lames de manière à créer un rideau ajouré à travers lequel passe la lumière. Les lames peuvent par exemple être accumulées en position haute du rideau avec une inclinaison de l'ordre de 0 à 30°.  On the other hand, it is also known that the rotation means comprise a motor, which is often the same as for the traction means, for rotating the own axes of the blades on themselves between extreme inclination positions. When the blades are vertical, the curtain is closed, the blades being joined. From this closed configuration, it is possible to tilt the blades so as to create a perforated curtain through which the light passes. The blades can for example be accumulated in the high position of the curtain with an inclination of the order of 0 to 30 °.
Un premier inconvénient avec les brise-soleil orientables conventionnels provient du mode d'accumulation des lames qui est dépendant de la gravité, de sorte que ces brise-soleil ne peuvent être installés que verticalement. Un autre inconvénient de ces brise-soleil orientables conventionnels est qu'ils n'offrent qu'une protection réduite contre l'infraction. En effet, lorsque les lames sont en configuration fermée verticale, elles sont certes jointives, mais une personne malveillante peut facilement les écarter et les déformer. Il existe donc un réel besoin de renforcement de la sécurité de ces brise-soleil orientables en configuration fermée pour réaliser un rideau anti-effraction. Encore un autre inconvénient de ces brise- soleil orientables conventionnels provient de l'utilisation d'un moteur unique servant à la fois à accumuler les lames en position haute du rideau et à faire tourner leurs axes propres.  A first disadvantage with conventional steerable sunshades is the gravity-dependent blade accumulation mode, so these sunshades can only be installed vertically. Another disadvantage of these conventional sunshades is that they offer only reduced protection against the infringement. Indeed, when the blades are in vertical closed configuration, they are certainly joined, but a malicious person can easily remove and deform. There is therefore a real need to increase the safety of these sunshades directional closed configuration to achieve a burglar-proof curtain. Yet another disadvantage of these conventional steerable sunshades is the use of a single motor to both accumulate the blades in the high position of the curtain and rotate their own axes.
Pour surmonter ces inconvénients, la présente invention propose un brise-soleil orientable définissant un rideau comprenant des lames longitudinales parallèles, chaque lame étant montée pivotante autour d'un axe propre longitudinal entre une configuration fermée dans laquelle les lames sont jointives et s'étendent sensiblement dans un même plan et une configuration ouverte dans laquelle les lames sont hors de contact les unes des autres pour former un rideau ajouré, le brise-soleil comprenant des moyens de rotation pour faire tourner simultanément les axes propres de sorte que les lames ont toujours la même orientation mutuelle, le brise-soleil comprenant en outre des moyens de traction pour accumuler les lames d'un côté du rideau en rapprochant leurs axes propres, alors que les lames sont dans une configuration ouverte, les moyens de rotation comprenant au moins une série de pantographes inclinables actionnés simultanément qui relie les axes propres entre eux, chaque pantographe comprend deux tiges inclinables connectées chacune à un axe propre, les tiges étant reliées entre elles à leurs extrémités libres par deux paires de bras articulés entre eux et sur les tiges, les moyens de traction comprenant au moins une série de parallélogrammes à actionnement simultané qui relie les axes propres entre eux, un axe est relié à un autre axe par un pantographe et un parallélogramme, de sorte que les lames s'accumulent en actionnant les moyens de traction avec les axes des lames se rapprochant simultanément, chaque lame comprenant des moyens d'accrochage longitudinaux pour accrocher les lames les unes aux autres dans la configuration fermée, caractérisé en ce que les axes propres des lames sont déplaçables les uns par rapport aux autres sur une course de verrouillage dans la configuration fermée pour verrouiller les moyens d'accrochage longitudinaux en prise mutuelle. Cette course de verrouillage est en effet utile pour connecter et déconnecter les lames entre elles alors que les lames sont verticales. To overcome these drawbacks, the present invention provides a sunshade defining a curtain comprising parallel longitudinal blades, each blade being pivotally mounted about a longitudinal axis between a closed configuration in which the blades are contiguous and extend substantially in the same plane and an open configuration in which the blades are out of contact with each other to form a perforated curtain, the sunshade comprising means of rotation to rotate simultaneously the proper axes of so that the blades always have the same mutual orientation, the sunscreen further comprising traction means for accumulating the blades on one side of the curtain by bringing their own axes, while the blades are in an open configuration, the means of rotation comprising at least one series of simultaneously operated tilt pantographs which connects the proper axes to each other, each pantograph comprises two tiltable rods each connected to a proper axis, the rods being interconnected at their free ends by two pairs of articulated arms between they and on the rods, the traction means comprising at least one series of parallelograms with simultaneous actuation which connects the proper axes between them, an axis is connected to another axis by a pantograph and a parallelogram, so that the blades s' accumulate by actuating the traction means with the axes of the blades approaching simultaneously, each blade comprising m longitudinal gripping means for hooking the blades together in the closed configuration, characterized in that the own axes of the blades are movable relative to each other on a locking stroke in the closed configuration to lock the means of longitudinal hooking in mutual engagement. This locking stroke is indeed useful for connecting and disconnecting the blades together while the blades are vertical.
D'autre part, les pantographes inclinables font tourner les axes propres des lames de manière synchrone de sorte que les lames ont toujours toutes la même orientation mutuelle, ces pantographes étant associés à des parallélogrammes à actionnement simultané qui permettent aux axes propres des lames d'avoir toujours le même écartement mutuel. En d'autres termes, les axes propres des lames se déplacent simultanément en se rapprochant ou en s'éloignant avec toujours le même écartement entre tous les axes. Ce n'est plus la lame d'extrémité inférieure qui vient cueillir les lames supérieures. Au contraire, le déplacement des lames s'effectue de manière simultanée et synchrone avec les entraxes des lames diminuant progressivement et simultanément. Le rapprochement ou l'éloignement des axes des lames est donc uniforme sur toute la hauteur du rideau. Le poids total des lames est certes supporté par la lame inférieure, mais il est transmis par la série de parallélogrammes à actionnement simultané. On the other hand, the tilting pantographs rotate the axes of the blades synchronously so that the blades always have the same mutual orientation, these pantographs being associated with simultaneous actuating parallelograms that allow the clean axes of the blades of always have the same mutual spacing. In other words, the own axes of the blades move simultaneously moving closer or further away with always the same spacing between all the axes. It is no longer the lower end blade that picks the upper blades. On the contrary, the displacement of the blades is performed simultaneously and synchronously with the spacings of the blades decreasing gradually and simultaneously. The approximation or distance of the axes of the blades is therefore uniform over the entire height of the curtain. The weight total blades is certainly supported by the lower blade, but it is transmitted by the parallelogram series of simultaneous actuation.
Selon un mode de réalisation pratique, chaque lame comprend deux bords longitudinaux parallèles pourvus chacun des moyens d'accrochage sous la forme d'un profil d'accrochage longitudinal apte à venir en prise avec un profil d'accrochage complémentaire d'une lame adjacente, le verrouillage/déverrouillage des profils résultant du déplacement des axes des lames sur la course de verrouillage.  According to a practical embodiment, each blade comprises two parallel longitudinal edges each provided with hooking means in the form of a longitudinal hooking profile capable of coming into engagement with a complementary hooking profile of an adjacent blade, the locking / unlocking of the profiles resulting from the movement of the axes of the blades on the locking stroke.
Avantageusement, les bras d'une paire présentent une configuration sensiblement alignée lorsque les axes des lames sont éloignés les uns des autres et une configuration sensiblement parallèle lorsque les axes des lames sont rapprochés, un bras de chaque paire étant extensible élastiquement, de sorte que sa longueur varie, notamment lors du déplacement des axes sur la course de verrouillage en configuration fermée pour verrouiller les moyens d'accrochage. De préférence, chaque paire de bras dans la configuration sensiblement alignée présente un léger angle mutuel qui est sensiblement constant lors des variations de longueur du bras élastiquement extensible.  Advantageously, the arms of a pair have a substantially aligned configuration when the axes of the blades are spaced from each other and a substantially parallel configuration when the axes of the blades are close together, an arm of each pair being elastically extensible, so that its length varies, especially when moving the axes on the locking stroke in closed configuration to lock the attachment means. Preferably, each pair of arms in the substantially aligned configuration has a slight mutual angle that is substantially constant during length variations of the elastically extensible arm.
Le verrouillage mutuel des lames entre elles est rendu possible par la combinaison synergique constituée par les parallélogrammes à actionnement simultané et les pantographes à bras extensibles. En effet, l'extension des bras des pantographes permet de déplacer les axes propres les uns par rapport aux autres en configuration fermée, c'est-à-dire avec les lames sensiblement verticales, et les parallélogrammes à actionne simultané permettent de maintenir tous les axes propres mutuellement équidistants. En termes de cycle opératoire, les lames sont dans un premier temps alignées verticalement en configuration fermée avec leurs moyens d'accrochage longitudinaux disposés les uns au-dessus des autres prêts à être engagés en prise mutuelle. Ensuite, les axes propres des lames sont écartés sur une faible course de verrouillage, ce qui permet de mettre les moyens d'accrochage longitudinaux en prise mutuelle et de les verrouiller entre eux de manière à former un rideau fermé unitaire. La solidarisation des lames entre elles sur leur longueur en configuration fermée du rideau est une caractéristique qui peut être mise en œuvre indépendamment des pantographes et des parallélogrammes décrits ci-dessus. En d'autres termes, une protection individuelle peut être recherchée pour cette seule caractéristique. The mutual interlocking of the blades with one another is made possible by the synergistic combination of the parallelogram parallelograms and the expandable pantographs. In fact, the extension of the arms of the pantographs makes it possible to move the proper axes relative to each other in closed configuration, that is to say with the substantially vertical blades, and parallelograms with simultaneous actuation make it possible to maintain all the mutually equidistant axes. In terms of the operating cycle, the blades are initially vertically aligned in a closed configuration with their longitudinal attachment means arranged one above the other ready to be engaged in mutual engagement. Then, the clean axes of the blades are spread over a small locking stroke, which allows to put the longitudinal hooking means in mutual engagement and to lock them together so as to form a unitary closed curtain. The joining of the blades together over their length in the closed configuration of the curtain is a characteristic that can be implemented independently of the pantographs and parallelograms described above. In other words, an individual protection can be sought for this characteristic alone.
Selon une forme particulièrement avantageuse de l'invention, les moyens de rotation comprennent un premier moteur pour incliner les pantographes et faire tourner les axes propres des lames, et les moyens de traction comprennent un second moteur, distinct du premier moteur, pour actionner les parallélogrammes à actionnement simultané et rapprocher/éloigner les axes propres des lames. Ainsi, le brise-soleil comprend deux moteurs distincts, dont le fonctionnement peut bien entendu être corrélé au moyen d'un boîtier de commande approprié. Avantageusement, le second moteur définit deux courses distinctes, à savoir une première course principale dans laquelle les lames sont dans la configuration ouverte et une seconde course de verrouillage dans laquelle les lames sont dans la configuration fermée. La seconde course de verrouillage permet d'accrocher et de verrouiller les lames entre elles sur leur longueur de manière à créer un rideau unitaire anti-effraction.  According to a particularly advantageous form of the invention, the rotation means comprise a first motor for tilting the pantographs and rotating the clean axes of the blades, and the traction means comprise a second motor, distinct from the first motor, for actuating the parallelograms. simultaneous actuation and bring / move the clean axes of the blades. Thus, the sunshade comprises two separate motors, whose operation can of course be correlated by means of a suitable control box. Advantageously, the second motor defines two distinct races, namely a first main race in which the blades are in the open configuration and a second locking race in which the blades are in the closed configuration. The second locking stroke allows to hang and lock the blades together along their length to create a unitary burglar-proof curtain.
Selon un autre aspect pratique de l'invention, la série de parallélogrammes à actionnement simultané comprend des nœuds d'axe solidaires des axes propres et des nœuds libres entre les axes propres, les nœuds libres de deux parallélogrammes adjacents étant reliés par paire par des barrettes rectilignes qui se croisent au niveau d'un nœud d'axe. Ainsi, chaque parallélogramme est formé par quatre moitiés de barrettes indépendantes articulées entre elles à chaque jonction.  According to another practical aspect of the invention, the series of parallelograms with simultaneous actuation comprises integral axis nodes of the proper axes and free nodes between the proper axes, the free nodes of two adjacent parallelograms being connected in pairs by strips rectilinear that intersect at a node axis. Thus, each parallelogram is formed by four halves of independent bars hinged together at each junction.
Selon une autre caractéristique intéressante de l'invention, les moyens de traction peuvent être en prise avec une lame d'extrémité qui est fixée de manière détachable à un élément de structure fixe, lorsque les moyens d'accrochage sont verrouillés. Ainsi, le rideau rendu unitaire par l'accrochage des lames entre elles est en outre verrouillé au niveau de sa lame d'extrémité, ce qui empêche de le soulever. Selon un autre aspect pratique, les moyens de traction comprennent une chaîne en boucle fermée qui est montée sur une roue menante entraînée en rotation par un moteur et une roue libre, la chaîne étant en prise avec la lame d'extrémité. En utilisant une chaîne en boucle fermée, associée à des parallélogrammes à actionnement simultané, on se libère de la gravité, de sorte que le brise-soleil de l'invention peut également être installé avec les lames disposées verticalement. According to another advantageous feature of the invention, the traction means can be engaged with an end plate which is detachably attached to a fixed structural element, when the attachment means are locked. Thus, the curtain made unitary by the attachment of the blades together is further locked at its end blade, which prevents lifting. In another practical aspect, the traction means comprise a closed-loop chain which is mounted on a driving wheel driven in rotation by a motor and a free wheel, the chain being engaged with the end plate. By using a closed-loop chain, associated with simultaneous actuating parallelograms, gravity is released, so that the sunshade of the invention can also be installed with the vertically arranged blades.
Un principe de l'invention réside dans le fait de déplacer les axes propres des lames de manière simultanée ou synchrone. Un autre principe de l'invention réside dans le fait d'accrocher et de verrouiller les lames entre elles sur leur longueur de manière à constituer un rideau unitaire anti- effraction. Un autre principe pratique réside dans le fait de déplacer les axes des lames alors que le rideau est dans la configuration fermée avec les lames verticales. Encore un autre principe de l'invention est d'utiliser deux moteurs distincts, respectivement pour relever et abaisser le rideau et pour faire tourner les axes propres des lames sur eux-mêmes.  One principle of the invention lies in the fact of moving the own axes of the blades simultaneously or synchronously. Another principle of the invention lies in the fact of hanging and locking the blades together over their length so as to form a unitary burglar-proof curtain. Another practical principle is the fact of moving the axes of the blades while the curtain is in the closed configuration with the vertical blades. Yet another principle of the invention is to use two separate motors, respectively to raise and lower the curtain and to rotate the own axes of the blades on themselves.
L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non limitatif un mode de réalisation de l'invention.  The invention will now be more fully described with reference to the accompanying drawings giving by way of non-limiting example an embodiment of the invention.

On se référera tout d'abord à la figure 1 pour décrire la structure générale d'un brise-soleil orientable incorporant la présente invention. De manière très générale, le brise-soleil orientable définit un rideau 1 comprenant une série de lames 1 1 qui sont parallèles entre elles et montées pivotantes autour d'axes propres longitudinaux 15 qui s'étendent parallèlement entre eux. Tous les axes 15 sont disposés dans un plan vertical, de sorte que les lames 1 1 sont disposées les unes au-dessus des autres avec un écartement variable, comme on le verra ci-après. L'inclinaison des lames peut varier en faisant tourner leurs axes propres longitudinal 15 sur eux-même. Ainsi, les lames peuvent pivoter entre une configuration fermée dans laquelle les lames sont sensiblement verticales et jointives dans le plan du rideau et une configuration ouverte dans laquelle les lames sont hors de contact les unes des autres pour former un rideau ajouré. Pour actionner les lames du rideau, le brise-soleil de l'invention comprend des moyens de rotation pour faire tourner les axes propres 15 des lames 1 1 et des moyens de traction pour accumuler les lames dans la partie supérieure du rideau en rapprochant leurs axes propres, alors que les lames 1 1 sont dans une configuration ouverte. Reference will first be made to Figure 1 to describe the general structure of a sunshade incorporating the present invention. In a very general manner, the sunshade defines a curtain 1 comprising a series of blades 1 1 which are parallel to each other and pivotally mounted about longitudinal proper axes 15 which extend parallel to each other. All the axes 15 are arranged in a vertical plane, so that the blades 1 1 are arranged one above the other with a variable spacing, as will be seen below. The inclination of the blades can vary by rotating their own longitudinal axes 15 on themselves. Thus, the blades can pivot between a closed configuration in which the blades are substantially vertical and contiguous in the plane of the curtain and an open configuration in which the blades are out of contact with each other to form a perforated curtain. To actuate the curtain blades, the sunshade of the invention comprises rotation means for rotating the own axes 15 blades 1 1 and traction means to accumulate the blades in the upper part of the curtain by bringing their axes clean, while the blades 1 1 are in an open configuration.
Les moyens de rotation comprennent un moteur électrique 21 qui fait tourner un arbre 22 relié à une série de pantographes inclinables 24 en prise avec les axes propres 15 des lames. D'autre part, les moyens de traction comprennent un moteur électrique 31 qui fait tourner un arbre 32 sur lequel est montée une roue menante 33m en prise avec une chaîne en boucle fermée 34 qui est également en prise avec une roue libre 33I. La chaîne 34 comprend une fixation 35 sur l'arbre 15 de la lame inférieure 1 1 e. Avantageusement, la chaîne 34 peut être pourvue d'un contrepoids 36, notamment lorsque le rideau est installé avec les lames disposées horizontalement. Les moyens de traction comprennent également une série de parallélogrammes à actionnement simultané 37 qui relient tous les axes propres 15 des lames 1 1 . La particularité de ces pantographes 37 est qu'ils imposent un rapprochement ou un éloignement simultané de tous les axes 15 des lames. En d'autres termes, il n'est pas possible de rapprocher deux axes 15 individuellement, sans rapprocher tous les autres axes du rideau simultanément. Il s'agit là d'une caractéristique particulière qui apporte un avantage dans le cadre de la présente invention, comme on le verra ci-après.  The rotation means comprise an electric motor 21 which rotates a shaft 22 connected to a series of tilting pantographs 24 in engagement with the proper axes 15 of the blades. On the other hand, the traction means comprise an electric motor 31 which rotates a shaft 32 on which is mounted a driving wheel 33m engaged with a closed-loop chain 34 which is also engaged with a free wheel 33I. The chain 34 comprises an attachment 35 on the shaft 15 of the lower blade 1 1 e. Advantageously, the chain 34 may be provided with a counterweight 36, particularly when the curtain is installed with the blades arranged horizontally. The traction means also comprise a series of simultaneous actuating parallelograms 37 which connect all the clean axes 15 of the blades 11. The particularity of these pantographs 37 is that they impose a simultaneous approach or a simultaneous removal of all the axes 15 of the blades. In other words, it is not possible to bring two axes 15 individually, without bringing all the other axes of the curtain together. This is a particular characteristic that provides an advantage in the context of the present invention, as will be seen below.
Comme on peut le voir sur la figure 1 , une série de pantographes 24 et une série de parallélogrammes 37 est située de part et d'autre du rideau 1 . Il n'est toutefois pas exclu qu'un brise-soleil selon l'invention ne comprenne qu'une seule série de pantographes 24 et/ou qu'une seule série de parallélogrammes à actionnement simultané 37 située sur un seul côté du rideau, notamment lorsque le rideau est installé avec ses lames verticalement. As can be seen in Figure 1, a series of pantographs 24 and a series of parallelograms 37 is located on either side of the curtain 1. However, it can not be ruled out that a sunshade according to the invention comprises only one series of pantographs 24 and / or a single series of simultaneous actuating parallelograms 37 located on one side of the curtain, in particular when the curtain is installed with its blades vertically.
Pour corréler et/ou synchroniser l'actionnement des moteurs 21 et 31 , il est prévu un boîtier de commande 4.  To correlate and / or synchronize the actuation of the motors 21 and 31, a control box 4 is provided.
On se référera maintenant également aux figures 2a et 2b pour expliquer en détail la structure des pantographes 24 et des parallélogrammes 37.  Reference will now also be made to FIGS. 2a and 2b to explain in detail the structure of pantographs 24 and parallelograms 37.
La série de parallélogrammes 37 comprend un assemblage de barrettes 38 reliées entre elles au niveau de nœud d'axe 38a et de nœud libre 38b. Chaque barrette 38 est montée de manière pivotante au niveau de son nœud d'axe 38a sur un axe propre 15 d'une lame 1 1 . Le nœud d'axe 38a est situé au milieu de la barrette 38. Deux barrettes 38 sont montées de manière croisée et pivotante sur un même axe 15. D'autre part, les extrémités libres des barrettes sont reliées entre elles au niveau des nœuds libres 38b. Ainsi, chaque parallélogramme est constitué par quatre moitiés de barrettes appartenant à quatre barrettes différentes. Les barrettes sont sensiblement rectilignes, bien qu'elles puissent présenter une certaine courbure, conservant toutefois l'alignement des nœuds libres 38 avec le nœud d'axe central 38a. De cette manière, la déformation des parallélogrammes ne peut s'effectuer que simultanément ou de manière synchrone : en d'autres termes, tous les parallélogrammes 37 de la série présentent la même forme à un instant donné. La forme des parallélogrammes peut bien entendu varier, mais de manière simultanée et synchronisée. Etant donné que les parallélogrammes relient tous les axes propres 15 des lames, le déplacement des axes 15 se fait également de manière simultanée et synchronisée. On peut remarquer que le parallélogramme supérieur 37 est relié à l'arbre 32 du moteur 31 . Ainsi, l'arbre 32 constitue le point de référence fixe, et tous les axes propres 15 vont se rapprocher et s'éloigner de cette référence fixe de manière simultanée en actionnant le moteur 31 . La chaîne 34 fixée à l'arbre 15 de la lame inférieure 1 1 e va imprimer une traction sur l'axe de cette lame, et la force de traction est transmise aux axes propres 15 des autres lames par la série de parallélogrammes 37. La série de parallélogrammes 37 agit ainsi comme un moyen de transmission de force à répartition égale. En conséquence, tous les axes propres 15 des lames vont se déplacer en rapprochement ou en éloignement de l'arbre 32 de manière simultanée et synchronisée. Sur la figure 3, on peut voir les barrettes 38 des parallélogrammes en position empilée correspondant à la position accumulée des lames en partie haute du rideau juste en dessous de l'arbre 32. On peut remarquer sur cette figure que les axes propres 15 sont très porches les uns des autres, par exemple distants de l'ordre de 1 cm à 1 ,5 cm. Cela permet d'accumuler par exemple vingt lames en moins de 30 cm. The series of parallelograms 37 comprises an assembly of bars 38 interconnected at node 38a and free node node 38b. Each bar 38 is pivotally mounted at its axis node 38a on a clean axis 15 of a blade January 1. The axis node 38a is located in the middle of the bar 38. Two bars 38 are pivotally mounted and pivotable on the same axis 15. On the other hand, the free ends of the bars are interconnected at the free nodes 38b. Thus, each parallelogram is constituted by four halves of bars belonging to four different bars. The bars are substantially rectilinear, although they may have a certain curvature, retaining however the alignment of the free nodes 38 with the central axis node 38a. In this way, the deformation of the parallelograms can be performed simultaneously or synchronously: in other words, all the parallelograms 37 of the series have the same shape at a given moment. The shape of the parallelograms can of course vary, but simultaneously and synchronized. Since the parallelograms connect all the own axes 15 of the blades, the movement of the axes 15 is also simultaneous and synchronized. It may be noted that the upper parallelogram 37 is connected to the shaft 32 of the motor 31. Thus, the shaft 32 constitutes the fixed reference point, and all the proper axes 15 will move closer and away from this fixed reference so that simultaneous by operating the motor 31. The chain 34 fixed to the shaft 15 of the lower blade 1 1 e will print a traction on the axis of this blade, and the traction force is transmitted to the own axes 15 of the other blades by the series of parallelograms 37. series of parallelograms 37 thus acts as a force distribution means equal distribution. Consequently, all the clean shafts 15 of the blades will move towards or away from the shaft 32 simultaneously and synchronously. In FIG. 3, we can see the bars 38 of the parallelograms in stacked position corresponding to the accumulated position of the blades in the upper part of the curtain just below the shaft 32. It can be seen in this figure that the proper axes 15 are very porches from each other, for example distant of the order of 1 cm to 1, 5 cm. This allows to accumulate for example twenty blades in less than 30 cm.
On peut également voir sur les figures 2a et 2b que les lames 1 1 comprennent deux bords longitudinaux pourvus de profils d'accrochage 12 et 13. Le bord supérieur de chaque lame comprend un profil d'accrochage supérieur 12 sous la forme d'un crochet orienté vers la gauche, alors que le bord inférieur des lames forme un profil d'accrochage 13 sous la forme d'un crochet orienté vers la droite. Ainsi, le profil d'accrochage supérieur 12 d'une lame peut venir en alignement et en prise avec un profil d'accrochage inférieur 13 d'une lame supérieure. Bien entendu, pour amener ces profils d'accrochage 12 et 13 en alignement et en prise, les lames 1 1 du rideau doivent être dans la configuration fermée, c'est-à-dire disposées avec une orientation sensiblement ou parfaitement verticale, comme on peut le voir sur les figures 2a et 2b. Sur la figure 2a, les profils d'accrochage 12, 13 sont alignés, mais ne sont pas en prise mutuelle. En revanche, sur la figure 2b, les profils d'accrochage 12, 13 sont en prises mutuelles, verrouillant ainsi les lames entre elles. Pour passer de la configuration de la figure 2a à celle de la figure 2b, il est nécessaire de déplacer les lames 1 1 en écartant leurs axes propres 15 sur une courte distance ou course de verrouillage. Sur la figure 2a, la distance entre deux axes 15 est de X, alors que sur la figure 2b la distance entre ces deux mêmes axes est de X + 4 mm. Les 4 mm sont en effet nécessaires pour permettre à deux profils d'accrochage adjacents 12 et 13 de venir en prise mutuelle verrouillante. Ainsi, la course de verrouillage est égale à 4 mm multipliés par le nombre total de lames du rideau. Bien entendu, le choix des 4 mm n'est pas limitatif. Pour permettre le déplacement des axes sur cette course de verrouillage, il est nécessaire que le moteur 31 puisse générer cette course de verrouillage en plus de la course principale permettant de relever et d'abaisser les lames du rideau. La course principale du moteur 31 est symbolisée entre les deux repères A et B de la figure 1 , et la course de verrouillage est symbolisée entre les repères B et C sur la figure 1 . Bien entendu, la course de verrouillage n'est possible que lorsque les lames 1 1 du rideau sont en configuration fermée correspondant à une fin de course E du moteur 21 visible sur la figure 1 . A l'autre extrémité de la course D, les lames sont en position inclinée dans la configuration ouverte permettant de constituer un rideau ajouré laissant passer la lumière. La synchronisation de fonctionnement des moteurs 21 et 31 est effectuée par le boîtier de commande 4, qui incorpore un circuit électronique approprié. It can also be seen in Figures 2a and 2b that the blades 1 1 comprise two longitudinal edges provided with attachment profiles 12 and 13. The upper edge of each blade comprises an upper attachment profile 12 in the form of a hook oriented to the left, while the lower edge of the blades forms a hooking profile 13 in the form of a hook oriented to the right. Thus, the upper attachment profile 12 of a blade can come in alignment and engaged with a lower attachment profile 13 of an upper blade. Of course, to bring these attachment profiles 12 and 13 into alignment and engagement, the blades 1 1 of the curtain must be in the closed configuration, that is to say arranged in a substantially or perfectly vertical orientation, as one can see it in Figures 2a and 2b. In Figure 2a, the attachment profiles 12, 13 are aligned, but are not in mutual engagement. In contrast, in Figure 2b, the attachment profiles 12, 13 are in mutual engagement, thus locking the blades together. To move from the configuration of Figure 2a to that of Figure 2b, it is necessary to move the blades 1 1 by moving their own axes 15 over a short distance or locking stroke. In Figure 2a, the distance between two axes 15 is X, while in Figure 2b the distance between these two axes is X + 4 mm. The 4 mm are in effect necessary to allow two adjacent latching profiles 12 and 13 to interlock each other. Thus, the locking stroke is equal to 4 mm multiplied by the total number of curtain blades. Of course, the choice of 4 mm is not limiting. To allow the movement of the axes on this locking stroke, it is necessary that the motor 31 can generate this locking stroke in addition to the main race for raising and lowering the curtain blades. The main stroke of the motor 31 is symbolized between the two marks A and B of FIG. 1, and the locking stroke is symbolized between the marks B and C in FIG. Of course, the locking stroke is only possible when the blades 1 1 of the curtain are in closed configuration corresponding to a limit switch E of the motor 21 visible in FIG. At the other end of the race D, the blades are in an inclined position in the open configuration to form a perforated curtain allowing the light to pass. The operating synchronization of the motors 21 and 31 is performed by the control box 4, which incorporates a suitable electronic circuit.
Il est ainsi possible selon l'invention d'accrocher et de verrouiller les lames entre elles le long de leurs bords longitudinaux pourvus de profils d'accrochage appropriés. La mise en prise des profils d'accrochage 12, 13 et leur verrouillage mutuel n'est possible que par le déplacement des axes propres 15 sur une courte course de verrouillage lorsque les lames du rideau sont en configuration fermée verticale. Il est bien entendu nécessaire que toutes les lames viennent en prise accrochée et verrouillée, et cela est rendu possible par la présence de la série de parallélogrammes à actionnement simultané 37 qui synchronise les déplacements mutuels des axes propres.  It is thus possible according to the invention to hook and lock the blades together along their longitudinal edges provided with appropriate attachment profiles. The engagement profiles 12, 13 and their mutual interlocking are only possible by moving the clean shafts 15 over a short locking path when the curtain blades are in a vertical closed configuration. It is, of course, necessary for all the blades to engage and lock in place, and this is made possible by the presence of the series of simultaneous actuating parallelograms 37 which synchronize the mutual displacements of the proper axes.
En outre, le déplacement des axes propres sur la course de verrouillage doit également tenir compte de la série de pantographes 24 dont la fonction est d'incliner les lames 1 1 en faisant leurs axes propres 15. En effet, les pantographes 24 sont également connectés à chaque axe propre 15, de sorte que chaque pantographe 24 doit s'accommoder du rapprochement/éloignement des axes propres sur la course de verrouillage. Cela n'est pas possible avec un pantographe classique de l'art antérieur, qui une fois déployé ne permet plus aucun déplacement des axes propres. Ainsi, la présente invention met en œuvre un pantographe de conception particulière autorisant l'éloignement et le rapprochement des axes propres 15 en configuration fermée avec les lames verticales. Pour ce faire, chaque pantographe 24 comprend deux tiges inclinables 25 reliées entre elles à leurs extrémités libres par deux paires de bras 26, 27 articulés entre eux et sur les tiges 25. La tige 25 connectée à l'arbre 15 de la lame supérieure est en outre reliée par deux fils ou câbles 23a à une tige de commande 23 montée fixement sur l'arbre 22 du moteur 21 . Ainsi, en faisant tourner le moteur 21 la tige de commande 23 change d'inclinaison, et communique cette inclinaison par l'intermédiaire des fils 23a à toute la série de pantographes 24, et ainsi à toutes lames jusqu'à la lame inférieure 1 1 e. Les tiges 23 et 25 pivotent de manière synchrone et simultanée par l'intermédiaire des bras 26, 27 et des fils 23a, de manière à faire tourner les axes propres 15 des lames sur eux-mêmes pour modifier l'inclinaison des lames. En se référant aux figures 2a et 2b, on voit plus clairement les bras 26 et 27 des pantographes 24. Selon l'invention, chaque paire de bras comprend un bras élastiquement extensible 27, de sorte que sa longueur varie. Plus précisément, ce bras 27 comprend deux parties de bras distincts 27a et 27b qui sont déplaçables l'une par rapport à l'autre à encontre d'un ressort de rappel 27c. Le bras 27 peut ainsi s'allonger, mais à encontre de la force du ressort 27c qui a tendance à le ramener vers sa position initiale de repos, qui est représentée sur la figure 2a. En revanche, sur la figure 2b, les bras 27 sont allongés en comprimant les ressorts 27c. L'allongement du bras 27c est de l'ordre de 4 mm, correspondant au déplacement des axes propres 15 sur la course de verrouillage. L'allongement des bras 27 permet de conserver la configuration globale des pantographes 24, avec les bras 26, 27 faisant un léger angle entre eux, comme on peut le voir sur les figures 2a et 2b. En effet, cet angle léger est sensiblement ou parfaitement conservé tout au long de la course de verrouillage, et cela est autorisé du fait de la variation de longueur du bras 27. En d'autres termes, le verrouillage des lames entre elles induit un allongement des bras 27 et une compression des ressorts 27c. On peut également remarquer que la compression des ressorts 27c permet d'éliminer tout jeu dans la structure du rideau 1 en position fermée verrouillée. In addition, the movement of the clean axes on the locking stroke must also take into account the series of pantographs 24 whose function is to tilt the blades 1 1 by making their axes 15. Indeed, the pantographs 24 are also connected each clean axis 15, so that each pantograph 24 must accommodate the approximation / removal of clean axes on the locking stroke. This is not possible with a conventional pantograph of the prior art, which once deployed no longer allows any movement of the clean axes. Thus, the present invention implements a pantograph of particular design allowing the distance and the approximation of the proper axes 15 in closed configuration with the vertical blades. To do this, each pantograph 24 comprises two tilting rods 25 interconnected at their free ends by two pairs of arms 26, 27 hinged together and on the rods 25. The rod 25 connected to the shaft 15 of the upper blade is further connected by two wires or cables 23a to a control rod 23 fixedly mounted on the shaft 22 of the motor 21. Thus, by rotating the motor 21, the control rod 23 changes its inclination, and communicates this inclination via the wires 23a to the whole series of pantographs 24, and thus to all the blades up to the lower blade 11 e. The rods 23 and 25 pivot synchronously and simultaneously through the arms 26, 27 and wires 23a, so as to rotate the own axes 15 of the blades on themselves to change the inclination of the blades. Referring to FIGS. 2a and 2b, the arms 26 and 27 of the pantographs 24 are more clearly seen. According to the invention, each pair of arms comprises an elastically extensible arm 27, so that its length varies. More specifically, this arm 27 comprises two separate arm portions 27a and 27b which are movable relative to each other against a return spring 27c. The arm 27 can thus lengthen, but against the force of the spring 27c which tends to return it to its initial rest position, which is shown in Figure 2a. In contrast, in Figure 2b, the arms 27 are elongated by compressing the springs 27c. The elongation of the arm 27c is of the order of 4 mm, corresponding to the displacement of the proper axes 15 on the locking stroke. The elongation of the arms 27 makes it possible to preserve the overall configuration of the pantographs 24, with the arms 26, 27 forming a slight angle between them, as can be seen in FIGS. 2a and 2b. Indeed, this slight angle is substantially or perfectly preserved throughout the locking stroke, and this is allowed because of the length variation of the arm 27. In other words, the locking of the blades between them induces an elongation arms 27 and a compression of springs 27c. It can also be noted that the compression of the springs 27c eliminates any play in the structure of the curtain 1 in the closed locked position.
Ainsi, un accrochage verrouillé des lames entre elles sur toute leur longueur est rendu possible par l'action simultanée des parallélogrammes à action simultané et des pantographes à bras extensibles. L'utilisation d'une chaîne continue contribue encore davantage à améliorer l'accrochage et le verrouillage des lames entre elles. Il faut noter que le brise-soleil de l'invention est totalement indépendant de l'action de la gravité, étant donné que les parallélogrammes sont à actionnement simultané et que la chaîne 34 est en boucle fermée. On peut ainsi utiliser la technologie du brise-soleil de l'invention pour réaliser un rideau dont les lames sont disposées verticalement.  Thus, locked locking blades between them over their entire length is made possible by the simultaneous action of simultaneous parallelograms and stretch arm pantographs. The use of a continuous chain further contributes to improving the attachment and locking of the blades together. It should be noted that the sunshade of the invention is completely independent of the action of gravity, since the parallelograms are simultaneous actuation and the chain 34 is closed loop. It is thus possible to use the technology of the brise-soleil of the invention to produce a curtain whose blades are arranged vertically.
Selon une autre caractéristique non représentée sur les figures, il est possible d'ancrer ou de verrouiller solidement la lame inférieure 1 1 e à un élément de structure fixe lorsque les lames sont verrouillées entre elles pour renforcer encore davantage la cohésion du rideau et ainsi améliorer sa sécurité contre une éventuelle effraction. En effet, étant donné que les lames sont accrochées et verrouillées entre elles sur la totalité de leur longueur, elles n'offrent aucune prise permettant de séparer deux lames. Et en verrouillant la lame inférieure, il n'est pas possible de saisir le rideau pour le détériorer.  According to another feature not shown in the figures, it is possible to anchor or securely lock the lower blade 1 1 e to a fixed structural element when the blades are locked together to further enhance the cohesion of the curtain and thus improve its security against possible break-in. Indeed, since the blades are hooked and locked together over their entire length, they offer no outlet for separating two blades. And by locking the lower blade, it is not possible to grasp the curtain to damage it.
Un cycle opératoire complet sera maintenant décrit pour améliorer la compréhension de l'invention. Au départ, toutes les lames 1 1 du rideau sont en position accumulée à proximité de l'arbre 32. Les lames sont alors dans une configuration ouverte, sensiblement horizontale ou avec un léger angle par exemple de l'ordre de 30°. Toutes les lames sont jointives, et les barrettes 38 des parallélogrammes sont également jointives, comme visible sur la figure 3. On commence alors par faire descendre les lames 1 1 du rideau en actionnant le moteur 31 , les orientations des lames restant inchangées. On peut ainsi faire descendre les lames du rideau 1 1 jusqu'à ce que la lame d'extrémité 1 1 e soit située à proximité du sol. On peut alors actionner le moteur 21 pour modifier l'inclinaison des lames par l'intermédiaire des pantographes 24. Les lames peuvent ainsi être amenées dans la configuration fermée verticale dans laquelle elles sont jointives. On se trouve alors dans la position de fin de course E du moteur 21 et dans la position de fin de course principale D du moteur 31 . Il est alors possible d'actionner à nouveau le moteur 31 pour effectuer la course de verrouillage entre B et C. Lors de cette course de verrouillage, les profils d'accrochage 12, 13 vont venir en prise verrouillée, et les bras 27 des pantographes 24 vont s'allonger en comprimant les ressorts 27c. On se trouve alors en position de fin de course C du moteur 31 . Dans cette position, la lame inférieure 1 1 e peut être verrouillée, par exemple à l'aide d'un ou de plusieurs verrou(s) électromagnétique(s) temporisé(s) au bas du tablier de la baie dans laquelle est monté le rideau. Lorsque l'utilisateur veut à nouveau faire remonter le rideau, la lame inférieure 1 1 e est déverrouillée et le moteur 31 est actionné pour effectuer la course de verrouillage de C vers B. A partir de là, on peut soit à nouveau utiliser le moteur 31 pour faire remonter le rideau, ou utiliser le moteur 21 pour incliner les lames du rideau. A complete operating cycle will now be described to improve the understanding of the invention. Initially, all the blades 1 1 of the curtain are in the accumulated position near the shaft 32. The blades are then in an open configuration, substantially horizontal or with a slight angle for example of the order of 30 °. All the blades are contiguous, and the bars 38 of the parallelograms are also contiguous, as can be seen in FIG. 3. Then, the blades 1 1 of the curtain are lowered by actuating the motor 31, the orientations of the blades remaining unchanged. It is thus possible to lower the curtain blades 1 1 until the end blade 1 1 e is located close to the ground. We can then actuate the motor 21 to change the inclination of the blades by means of the pantographs 24. The blades can thus be brought into the vertical closed configuration in which they are joined. It is then in the end-of-travel position E of the engine 21 and in the main end-of-travel position D of the engine 31. It is then possible to actuate the motor 31 again to perform the locking stroke between B and C. During this locking stroke, the attachment profiles 12, 13 will come into locked engagement, and the arms 27 of the pantographs 24 will lengthen by compressing the springs 27c. It is then in end position C of the motor 31. In this position, the lower blade 1 1 e can be locked, for example by means of one or more electromagnetic lock (s) timed (s) at the bottom of the deck of the bay in which is mounted curtain. When the user wants to raise the curtain again, the lower blade 1 1 e is unlocked and the motor 31 is actuated to perform the locking stroke C to B. From there, we can either use the motor again 31 to raise the curtain, or use the motor 21 to tilt the curtain blades.
Grâce à l'invention, on dispose d'un brise-soleil orientable qui offre une grande sécurité contre l'effraction en configuration fermée.  Thanks to the invention, there is an adjustable sunshade that provides great security against burglary in closed configuration.
