Description

La présente invention a trait à un vitrage isolant dans lequel est incorporé un store perfectionné. Par « vitrage isolant » on désigne ici communément un vitrage comportant au moins deux panneaux de verre et/ou d'une matière plastique transparente telle que polycarbonate, poly(méthacrylate de méthyle) ou similaire, assemblés par un cadre périphérique, qui enferment une lame intercalaire d'un gaz, notamment de l'air pouvant être déshydraté quand la structure du vitrage est apte à garantir l'étanchéité requise. Ce type de vitrage procure une isolation thermique et phonique améliorée.The present invention relates to insulating glazing in which is incorporated an improved blind. By “insulating glass” we mean here commonly glazing comprising at least two glass panels and / or a transparent plastic material such as polycarbonate, poly (methyl methacrylate) or similar, assembled by a frame peripheral, which enclose an intermediate plate of a gas, in particular of air can be dehydrated when the glazing structure is suitable for guarantee the required tightness. This type of glazing provides insulation thermal and phonic improved.

Les vitrages isolants sont fréquemment associés à des stores externes, par exemple des stores vénitiens consistant en général en des ensembles de lames susceptibles de pivoter selon des axes horizontaux, entre une position verticale d'obturation et une position horizontale autorisant le passage d'une partie substantielle des rayons lumineux. De tels stores externes présentent cependant deux types d'inconvénients.Insulating glass is frequently associated with blinds external, for example venetian blinds generally consisting of sets of blades capable of pivoting along horizontal axes, between a vertical shutter position and a horizontal position authorizing the passage of a substantial part of the light rays. Of such external blinds however have two types of drawbacks.

En premier lieu, ils ont une tendance à retenir de grandes quantités de poussière, ce qui nécessite des opérations de nettoyage rendues problématiques par la complexité de forme du store.First, they have a tendency to retain large amounts dust, which requires cleaning operations made problematic by the complexity of the shape of the blind.

En second lieu, ces stores sont fragiles et il convient d'éviter autant que possible de le soumettre à des chocs ou à des manipulations erronées. Second, these blinds are fragile and as much should be avoided as possible to subject it to impact or incorrect handling.

Ces deux problèmes ont pu être résolus conformément à un art antérieur représenté par le brevet FR 2 697 281 par l'intégration du store vénitien dans la lame d'air délimitée par deux feuilles de verre d'un vitrage isolant. Ce montage isole le store de l'atmosphère plus ou moins poussiéreuse et il permet en outre de séparer les différents organes de commande du store ― ficelles ou similaire- les uns des autres dans des espaces conformés à cet effet dans le cadre du vitrage isolant, ce qui est de nature à diminuer le risque de manipulations incorrectes. Il nécessite éventuellement d'adapter la largeur des lames du store à celle de la lame d'air, c'est à dire de la diminuer jusqu'à des valeurs aussi faibles dans certains cas que 1 à 2 mm.These two problems could be solved in accordance with an art represented by patent FR 2 697 281 by the integration of the blind Venetian in the air space delimited by two sheets of glass insulating. This assembly isolates the blind from the atmosphere more or less dusty and it further helps separate the different organs from blind control - twine or the like - from each other in spaces designed for this purpose in the context of insulating glass, which is likely to reduce the risk of improper handling. It needs possibly adapt the width of the blind blades to that of the blade air, i.e. decrease it to such low values in some cases as 1 to 2 mm.

Dans le cadre décrit précédemment, l'invention a cependant répondu au besoin d'améliorer les stores connus, mais sur un autre plan que celui de leur intégration dans un vitrage isolant. Dans le cas des stores vénitiens courants, par exemple, l'une de leurs caractéristiques est que toutes les lames qu'ils comprennent définissent des plans parallèles. Il en résulte que le degré de filtration du rayonnement lumineux, de la visibilité la moins altérée possible correspondant à une quasi-absence de filtration, jusqu'à l'obturation, est presque identique sur toute la hauteur du store, aux variations de l'angle d'incidence du rayonnement près. Or une fonctionnalité du store vis-à-vis du rayonnement lumineux différenciée selon la hauteur peut être recherchée.In the context described above, the invention has however responded to the need to improve known blinds, but on another level than that of their integration in insulating glass. In the case of common venetian blinds for example one of their features is that all the blades they understand define parallel planes. he As a result, the degree of filtration of the light radiation, of the least impaired visibility possible corresponding to a virtual absence of filtration, until obturation, is almost identical over the entire height of the blind, to variations in the angle of incidence of the near radiation. Gold a functionality of the blind vis-à-vis the light radiation differentiated by height can be searched.

Il peut ainsi être souhaitable d'obturer une partie supérieure d'un vitrage pour limiter l'apport de chaleur dû au rayonnement lumineux pendant que les lames d'une partie inférieure sont en position de visibilité, ou au contraire de régler les lames d'une partie supérieure d'un vitrage en position sensiblement horizontale pour qu'elles réfléchissent le rayonnement lumineux sur le plafond tout en obturant une partie inférieure.It may thus be desirable to seal an upper part of a glazing to limit the heat input due to light radiation while the blades of a lower part are in the visibility position, or on the contrary to adjust the blades of an upper part of a glazing in substantially horizontal position so that they reflect the light radiation on the ceiling while blocking part lower.

Plusieurs dispositifs ont été conçus à cet effet.Several devices have been designed for this purpose.

La demande EP 0 513 468 A1 décrit un store vénitien dont la partie inférieure est constituée d'une nappe continue pliable verticalement en accordéon, au lieu de lames disjointes. La seule fonctionnalité possible de cette partie inférieure est donc l'obturation. Application EP 0 513 468 A1 describes a Venetian blind, the part of which bottom consists of a continuous ply vertically foldable in accordion, instead of disjointed blades. The only possible functionality of this lower part is therefore the obturation.

Le modèle d'utilité DE 298 15 654 U1 et la demande EP 0 899 411 A2 décrivent un double store intégré dans un vitrage isolant, constitué d'un système supérieur de lames et d'un système inférieur de lames fixés tous deux à un élément intermédiaire horizontal. Celui-ci constitue un obstacle à la vision, et ces dispositifs ne permettent pas de libérer au moins une zone à hauteur moyenne du vitrage de tout élément de store.The utility model DE 298 15 654 U1 and the application EP 0 899 411 A2 describe a double blind integrated in insulating glass, consisting of an upper system of blades and a lower system of blades both fixed to a horizontal intermediate element. This one is an obstacle to vision, and these devices do not allow free at least one zone at medium height of the glazing from any element of awning.

Par conséquent l'invention a pour but la mise à disposition d'un store permettant de différencier le degré de filtration du rayonnement lumineux d'au moins une partie haute et d'au moins une partie basse et de dégager au moins une zone à hauteur moyenne du vitrage de tout élément de store.Consequently, the object of the invention is to provide a awning to differentiate the degree of filtration of radiation bright at least one upper part and at least one lower part and clear at least one zone at medium height of the glazing from all blind element.

Ce but est atteint par l'invention qui en conséquence a pour objet un store comprenant au moins une partie supérieure et une partie inférieure. L'invention réside plus particulièrement dans le fait que la partie supérieure, respectivement la partie inférieure peuvent être confinées dans leur intégralité et indépendamment l'une de l'autre dans une partie haute, respectivement une partie basse de la baie pour laquelle le store est utilisé.This object is achieved by the invention which consequently relates to a blind comprising at least an upper part and a part lower. The invention lies more particularly in the fact that the upper part respectively the lower part can be contained in their entirety and independently of each other in an upper part, respectively a lower part of the bay for which the blind is used.

L'invention, par la mise à disposition de deux parties de store séparées, autorise pour chacune des deux parties un réglage du degré de filtration du rayonnement lumineux différencié. La conception d'organes de commandes différents pour chacune des deux parties est aisée.The invention, by providing two parts of the blind separate, authorizes for each of the two parts an adjustment of the degree of filtration of differentiated light radiation. Organ design different commands for each of the two parts is easy.

D'autre part le confinement de la partie supérieure et de la partie inférieure en haut et en bas de la baie permet d'en dégager une partie de hauteur moyenne, jusqu'à la quasi-totalité de sa surface, de tout élément de store, et autorise dans cette zone une vision sans obstacle.On the other hand, the containment of the upper part and the part lower at the top and bottom of the bay makes it possible to release part of it average height, to almost all of its surface, of any element awning, and allows unobstructed vision in this area.

Bien que les stores à lames du type stores vénitiens aient été mentionnés précédemment, tout moyen d'occultation et/ou filtration graduelle du rayonnement lumineux peut enter dans la constitution desdites parties supérieure et inférieure de store : à ce titre peuvent être cités des panneaux mobiles en voiles ou tissus divers, ou en matériaux aptes à changer de couleur, à foncer ou à passer d'un état opaque à un état translucide ou transparent, de manière réversible sous l'effet de diverses excitations, tels que des matériaux électrochromes, photochromes, à cristaux liquides ou similaires.Although the Venetian blind type blinds have been mentioned above, any means of concealment and / or filtration gradual light radiation can enter the constitution said upper and lower parts of the blind: as such may be cited moving panels in sails or various fabrics, or in materials able to change color, darken or go from an opaque state to a translucent or transparent state, reversibly under the effect of various excitations, such as electrochromic materials, photochromic, liquid crystal or the like.

Bien entendu, il est envisageable, voire recommandé en cas de recherche d'effets différents pour la partie supérieure et la partie inférieure, d'utiliser des matériaux, couleurs et systèmes et principes de filtration du rayonnement différents pour les deux parties. A cet égard peut être mentionné l'emploi d'un store vénitien pour la partie supérieure et d'un tissu réfléchissant pour la partie inférieure, ou l'inverse. Tel est le cas notamment lorsque l'on recherche un effet dit de « daylighting » consistant en une réflexion et une diffusion du rayonnement lumineux incident vers le haut.Of course, it is possible, even recommended in case of search for different effects for the upper part and the part use materials, colors and systems and principles of filtration of different radiation for the two parts. In this regard may be mentioned the use of a venetian blind for the upper part and a reflective fabric for the bottom, or vice versa. This is the especially when looking for a so-called "daylighting" effect consisting of reflection and scattering of light radiation incident up.

Selon les cas il est aisément compréhensible que le mode de confinement desdites parties supérieure et inférieure comprendra un empilement et/ou un pliage et/ou un enroulement...Depending on the case, it is easily understandable that the mode of containment of said upper and lower parts will include a stacking and / or folding and / or winding ...

Cependant, conformément à une variante préférée de l'invention, le store comprend au moins un ensemble de lames supérieur et un ensemble de lames inférieur, les lames de l'ensemble supérieur et les lames de l'ensemble inférieur étant susceptibles de pivoter indépendamment les unes des autres, un élément d'extrémité inférieure dudit ensemble supérieur, respectivement un élément d'extrémité supérieure dudit ensemble inférieur étant reliés aux lames de l'ensemble auquel ils appartiennent de manière à pouvoir toutes successivement les entraíner vers le haut, respectivement vers le bas.However, in accordance with a preferred variant of the invention, the blind includes at least one set of upper slats and one set of lower blades, the blades of the upper assembly and the blades of the lower assembly being capable of pivoting independently from each other, a lower end element of said assembly upper, respectively an upper end member of said lower assembly being connected to the blades of the assembly to which they belong so that you can train them all successively up, respectively down.

Ce store vénitien rend simultanément possibles

  • tout positionnement angulaire des lames de l'ensemble supérieur, c'est à dire de la position horizontale à la position verticale, et de même et indépendamment de celui-ci, tout positionnement angulaire des lames de l'ensemble inférieur ;
  • le rassemblement progressif vers le haut des lames de l'ensemble supérieur par mouvement ascendant de l'élément d'extrémité inférieure de cet ensemble et/ou le rassemblement progressif vers le bas des lames de l'ensemble inférieur par mouvement descendant de l'élément d'extrémité supérieure de cet ensemble.
This Venetian blind simultaneously makes possible
  • any angular positioning of the blades of the upper assembly, that is to say from the horizontal position to the vertical position, and likewise and independently of the latter, any angular positioning of the blades of the lower assembly;
  • the progressive gathering up of the blades of the upper assembly by upward movement of the lower end element of this assembly and / or the progressive gathering downward of the blades of the lower assembly by downward movement of the element upper end of this set.

En faisant pivoter les lames hautes et basses selon des angles différents, une proportion plus ou moins importante du rayonnement lumineux est autorisée à pénétrer dans l'enceinte délimitée, selon un angle plus ou moins fermé, c'est à dire une déviation du rayonnement plus ou moins importante.By rotating the top and bottom boards at angles different, a greater or lesser proportion of the radiation light is authorized to enter the demarcated enclosure, according to a more or less closed angle, i.e. a deflection of the radiation more or less important.

Les hauteurs des ensembles de lames supérieur et inférieur sont variables l'une en fonction de l'autre d'une valeur minimale faible à la quasi-totalité de la hauteur du vitrage.The heights of the upper and lower blade assemblies are variables one as a function of the other from a low minimum value to the almost the entire height of the glazing.

La hauteur de la zone comprise entre les ensembles de lames supérieur et inférieur, ne présentant pas d'obstacle à la vision, varie d'une valeur nulle à la quasi-totalité de la hauteur du vitrage.The height of the area between the blade assemblies upper and lower, not presenting any obstacle to vision, varies from zero value at almost the entire height of the glazing.

D'autre part l'emploi de lames présentant une concavité sur toute leur longueur est connu. L'orientation vers le haut de la concavité des lames de l'ensemble supérieur favorise la réflexion du rayonnement lumineux vers le haut, notamment vers le plafond. De manière similaire l'orientation vers le bas de la concavité des lames de l'ensemble inférieur tend à rabattre la lumière vers le sol et est de nature à éviter dans une certaine mesure l'éblouissement des occupants de l'enceinte délimitée.On the other hand the use of blades having a concavity on all their length is known. The upward orientation of the concavity of blades of the upper assembly promotes the reflection of radiation bright upwards, especially towards the ceiling. In the same way the downward orientation of the concavity of the blades of the lower assembly tends to bend the light towards the ground and is likely to avoid in a to some extent the glare of the occupants of the demarcated enclosure.

Selon un mode de réalisation préféré de l'invention, les lames et l'élément d'extrémité inférieure de l'ensemble supérieur d'une part, les lames et l'élément d'extrémité supérieure de l'ensemble inférieur d'autre part, sont reliés les unes à l'autre par des fils de chaínes verticaux en échelles transmettant le pivotement aux lames.According to a preferred embodiment of the invention, the blades and the lower end element of the upper assembly on the one hand, the blades and the top end element of the bottom assembly else part, are connected to each other by vertical chain wires in scales transmitting pivoting to the blades.

Dans une réalisation particulièrement pratique de l'invention, l'élément d'extrémité supérieure de l'ensemble de lames inférieur comporte un axe maintenu horizontal à une hauteur choisie et réglable.In a particularly practical embodiment of the invention, the upper end member of the lower blade assembly includes an axis kept horizontal at a chosen and adjustable height.

D'autre part l'invention a également pour objet un vitrage isolant comportant deux panneaux transparents assemblés par un cadre périphérique, qui enferment une lame intercalaire d'air, entre lesquels est positionné un store vénitien tel que décrit ci-dessus.On the other hand, the invention also relates to insulating glazing. comprising two transparent panels assembled by a frame peripheral, which enclose an interlayer of air, between which is positioned a Venetian blind as described above.

D'autres caractéristiques et avantages de l'invention apparaítront dans la description qui suit du dessin en annexe, qui est une représentation schématique partielle éclatée d'un double store vénitien conforme à l'invention, d'éléments de montage de celui-ci et d'éléments d'un vitrage isolant dans lequel le store est intégré.Other characteristics and advantages of the invention will appear in the following description of the attached drawing, which is a partial schematic exploded view of a double Venetian blind according to the invention, mounting elements thereof and elements insulating glass in which the blind is integrated.

L'ensemble de lames supérieur 1 est fixé au montant horizontal supérieur du cadre de montage du vitrage isolant, à l'intérieur de la lame d'air déshydraté, par l'intermédiaire d'un profilé creux parallélépipédique en deux parties 10a, 10b ; l'ensemble de lames inférieur 2 est fixé au montant horizontal inférieur du cadre de montage du vitrage isolant par l'intermédiaire d'un profilé creux parallélépipédique en deux parties 11a, 11b.Is integrated into the insulating glass, i.e. in the defined space by sheets 5, 6 and their mounting frame, a Venetian blind made up an upper blade assembly 1 and a lower blade assembly 2. The upper blade assembly 1 is fixed to the horizontal upright upper of the insulating glass mounting frame, inside the blade dehydrated air, via a hollow parallelepiped profile in two parts 10a, 10b; the lower blade assembly 2 is fixed to the lower horizontal upright of the insulating glazing mounting frame by through a hollow parallelepiped profile in two parts 11a, 11b.

D'autre part, l'ensemble de lames supérieur 1 comprend un élément d'extrémité inférieure 3 rigide relié aux lames de l'ensemble 1 par des fils de chaínes verticaux 7 en échelles. De tels fils en échelles sont manoeuvrés de l'extérieur selon un fonctionnement bien connu de manière à faire pivoter ensemble l'élément 3 et les lames de l'ensemble 1, de la sorte constamment orientés selon des plans parallèles.On the other hand, the upper blade assembly 1 comprises an element rigid end 3 connected to the blades of the assembly 1 by wires of vertical chains 7 in scales. Such ladder threads are operated from the outside according to a well-known way of operating to rotate together the element 3 and the blades of the assembly 1, of the so constantly oriented in parallel planes.

Les mêmes relations fonctionnelles existent entre les lames de l'ensemble inférieur 2 et l'élément d'extrémité supérieure 4 de cet ensemble 2 qui sont reliés par des fils de chaínes verticaux en échelles 8. L'élément 4 est monté à rotation autour de son axe de symétrie longitudinal 9, dont chacune des deux extrémités est assemblée à un élément d'entraínement 12, un seul des deux éléments 12 étant représenté. Chacun des deux éléments 12 peut glisser verticalement à l'intérieur d'un profilé creux 13 présentant sur toute sa hauteur une rainure qui permet la liaison de l'axe 9 à l'élément 12. Les profilés creux 13 sont fixés sur les montants latéraux verticaux du cadre de montage du vitrage isolant, dans la lame d'air déshydraté. Chaque élément 12 comporte un alésage fileté d'axe vertical, destiné à coopérer avec une tige filetée 14 installée dans le profilé 13. L'extrémité inférieure de la tige filetée 14 consiste en un engrenage conique 15 en prise avec un engrenage conique 16 en prolongement d'un arbre horizontal dont l'axe coïncide avec l'axe de symétrie longitudinal du profilé creux 11a, 11b. Cet arbre est susceptible d'être mis en rotation soit au moyen de commandes manuelles extérieures au vitrage, soit au moyen d'un moteur, notamment électrique, pouvant être intégré dans le profilé creux 11a, 11b. Il en résulte une mise en rotation de la tige filetée 14, déplaçant vers le haut ou vers le bas, selon le sens de rotation dudit arbre et de la tige filetée 14, l'élément d'entraínement 12 et l'élément d'extrémité supérieure 4. Bien que le mécanisme associant l'élément d'entraínement 12, le profilé 13, la tige filetée 14 et les engrenages coniques 15 et 16 ne soit représenté sur la figure que du côté gauche du vitrage, un dispositif analogue est également présent du côté droit. Cependant, dans d'autres variantes, ce dispositif analogue est absent du côté droit.The same functional relationships exist between the blades of the lower assembly 2 and the upper end element 4 of this set 2 which are connected by vertical chain wires in ladders 8. Element 4 is mounted for rotation about its axis of symmetry longitudinal 9, each of the two ends of which is assembled to a drive element 12, only one of the two elements 12 being represented. Each of the two elements 12 can slide vertically at the interior of a hollow section 13 having over its entire height a groove which allows the connection of the axis 9 to the element 12. The hollow profiles 13 are fixed on the vertical lateral uprights of the mounting frame of the insulating glass, in the dehydrated air space. Each element 12 has a threaded bore with a vertical axis, intended to cooperate with a rod threaded 14 installed in profile 13. The lower end of the threaded rod 14 consists of a bevel gear 15 engaged with a gear conical 16 in extension of a horizontal shaft whose axis coincides with the longitudinal axis of symmetry of the hollow section 11a, 11b. This tree is capable of being rotated either by manual controls external to the glazing, either by means of a motor, in particular an electric motor, can be integrated into the hollow profile 11a, 11b. This results in a stake in rotation of the threaded rod 14, moving up or down, depending on the direction of rotation of said shaft and of the threaded rod 14, the element 12 and the upper end element 4. Although the mechanism associating the drive element 12, the profile 13, the rod threaded 14 and the bevel gears 15 and 16 is shown on the figure that on the left side of the glazing, a similar device is also present on the right side. However, in other variants, this device analog is absent on the right side.

Un dispositif analogue peut également être employé pour déplacer verticalement l'élément d'extrémité inférieure 3.A similar device can also be used to move vertically the lower end element 3.
