Description

STORE A LAMELLES LAMELLA BLINDS
Domaine de 1'invention Field of the invention
La présente invention concerne le domaine des stores à lamelles dits « stores vénitiens » pour l'occultation de fenêtres et le réglage de la luminosité dans une pièce éclairée par des fenêtres. Ces stores sont constitués de lamelles horizontales parallèles entre elles que l'on oriente au moyen de cordons. The present invention relates to the field of slatted blinds known as “Venetian blinds” for blocking out windows and adjusting the brightness in a room lit by windows. These blinds consist of horizontal slats parallel to each other which are oriented by means of cords.
Un store vénitien permet d'occulter la lumière et de moduler la luminosité tout en contrôlant la possibilité de voir ou d'être vu. A Venetian blind allows the light to be obscured and the brightness to be modulated while controlling the possibility of seeing or being seen.
Par exemple, dans un rez-de-chaussée, en orientant les lamelles vers le haut, on laisse passer la lumière extérieure, mais on ne préserve pas son intimité, les passants ayant une vue directe dans la pièce et lorsqu'on incline les lamelles, on opacifie la vitre. For example, in a ground floor, by orienting the slats upwards, we let outside light pass, but we do not preserve its privacy, passers-by having a direct view in the room and when tilting the slats , we opacify the glass.
Toutefois, dans des logements situés dans des ruelles étroites où la lumière du soleil n'arrive pas à pénétrer dans les pièces, ces solutions ne sont pas très satisfaisantes car elles obligent à vivre tout le temps dans la pénombre si on veut préserver son intimité. However, in dwellings located in narrow streets where the sunlight cannot penetrate into the rooms, these solutions are not very satisfactory because they make it necessary to live in semi-darkness all the time if you want to preserve your privacy.
On a proposé de pallier cet inconvénient par des stores vénitiens équipés de miroirs qui renvoient la lumière extérieure vers l'intérieur de la pièce, mais l'occulte lorsque les lamelles sont inclinées pour préserver l'intimité. It has been proposed to overcome this drawback by Venetian blinds equipped with mirrors which reflect the exterior light towards the interior of the room, but the occult when the slats are inclined to preserve privacy.
État de la technique State of the art
On connaît dans l'état de la technique le brevet français FR3080643 décrivant une solution efficace de store vénitien permettant suivant sa position d'éclairer l'intérieur de la pièce par réflexion de la lumière extérieure sur des miroirs apposés sur les lames pivotantes, et d'occulter, suivant le réglage, la vue vers l'intérieur de la pièce. Ce brevet propose un store vénitien constitué de lamelles présentant une face intérieure réfléchissante orientables montées sur un système de câbles relié à une commande pour décaler les câbles supportant l'avant des lamelles par rapport aux câbles supportant l'arrière des lamelles caractérisé en ce que lesdites lamelles sont orientables, assurant la réflexion de la lumière extérieure zénithale, le bord transversal intérieur desdites lamelles étant prolongé par une bande opaque d'une hauteur comprise entre 0,8 et 1,1 fois l'intervalle entre projection, sur le plan arrière du store, du bord avant de la lamelle portant ladite bande opaque, et le bord arrière de la lamelle inférieure adjacente. French patent FR3080643 is known in the state of the art, describing an effective solution for a venetian blind making it possible, depending on its position, to illuminate the interior of the room by reflection of the exterior light on mirrors affixed to the pivoting slats, and of '' hide, depending on the setting, the view towards the interior of the room. This patent proposes a Venetian blind made up of slats having an orientable reflecting inner face mounted on a system of cables connected to a control for shifting the cables supporting the front of the slats relative to the cables supporting the rear of the slats, characterized in that said lamellae are orientable, ensuring the reflection of the external zenithal light, the internal transverse edge of said lamellae being extended by an opaque strip with a height of between 0.8 and 1.1 times the interval between projection, on the rear plane of the blind, from the front edge of the slat carrying said opaque strip, and the rear edge of the adjacent lower slat.
Cette solution est globalement satisfaisante, mais nécessite un système de cordelettes, pour orienter les lamelles, suivant un cheminement relativement complexe. This solution is generally satisfactory, but requires a system of cords, to orient the slats, following a relatively complex path.
On connaît aussi la demande de brevet international WO/2010/125258 décrivant une solution consistant à recouvrir une face des lamelles d'un store ou de persiennes orientables d'une surface absorbante et l'autre face d'une surface réfléchissante afin d'absorber ou de réfléchir la chaleur suivant l'orientation choisie. Cela revient à installer une climatisation naturelle tout en laissant passer la lumière. International patent application WO / 2010/125258 is also known, describing a solution consisting in covering one face of the slats of a blind or of adjustable shutters with an absorbent surface and the other face with a reflecting surface in order to absorb. or to reflect the heat according to the chosen orientation. This amounts to installing natural air conditioning while allowing light to pass through.
La demande de brevet japonais JP2011179225 décrit un autre exemple visant à laisser passer la lumière du soleil dont la hauteur varie selon la saison dans une serre agricole. Le store est constitué de lattes en bois plat comportant un film de réflexion collé sur la surface supérieure de la latte. La lumière du soleil est transmise dans la serre en ajustant l'angle de chaque latte. Japanese patent application JP2011179225 describes another example aimed at letting sunlight, the height of which varies according to the season, to pass through an agricultural greenhouse. The blind is made of flat wooden slats with a reflection film bonded to the top surface of the slat. Sunlight is transmitted into the greenhouse by adjusting the angle of each slat.
On connaît aussi dans l'état de la technique le brevet américain US2155985 décrivant un store vénitien formé de lamelles rigides réfléchissantes pliées pour former deux ailes formant entre elles un angle constant d'environ 145°. Also known in the state of the art is US patent US2155985 describing a venetian blind formed of rigid reflective slats bent to form two wings forming between them a constant angle of about 145 °.
On connaît aussi la demande de brevet américain US2006/219370 décrivant un habillage de fenêtre comportant des éléments d'ombrage rabattables en forme de lattes espacés. Chaque élément de store possède un rabat s'étendant à partir d'un ou des deux bords longitudinaux des éléments de store. L'espace entre les éléments d'ombre adjacents est supérieur à la largeur des éléments d'ombre et inférieur ou égal à la largeur de l'élément d'ombre plus la largeur du volet. Des cordons sont attachés aux bords longitudinaux des éléments d'ombrage de sorte que les éléments d'ombrage peuvent être inclinés ou pliés par rapport aux volets. Also known is the American patent application US2006 / 219370 describing a window covering comprising hinged shade elements in the form of spaced slats. Each shade element has a flap extending from one or both longitudinal edges of the shade elements. The space between adjacent shadow elements is greater than the width of the shadow elements and less than or equal to the width of the shadow element plus the width of the pane. Cords are attached to the longitudinal edges of the shading elements so that the shading elements can be tilted or bent relative to the shutters.
Inconvénients de l'art antérieur Disadvantages of the prior art
Pour des habitats dans des ruelles sombres, les solutions de l'art antérieur ne sont pas satisfaisantes car la lumière du soleil ne peut pratiquement pas pénétrer dans les pièces, lorsque l'immeuble en face est très proche. Par ailleurs, il est très difficile de préserver dans de telles situations de proximité des immeubles l'intimité par des stores vénitiens selon l'état de la technique. En effet, pour laisser passer un minimum de lumière, il est nécessaire de réduire le niveau d'occultation . For dwellings in dark alleys, the solutions of the prior art are not satisfactory because the sunlight can hardly penetrate into the rooms, when the building opposite is very close. Furthermore, it is very difficult in such situations of proximity to buildings to preserve privacy by venetian blinds according to the state of the art. Indeed, to allow a minimum of light to pass, it is necessary to reduce the level of blackout.
La solution décrite dans le brevet FR3080643 évite ce problème mais présente des fragilités en raison de la complexité du cheminement des cordelettes d'orientation des lames-miroirs . The solution described in patent FR3080643 avoids this problem but has weaknesses due to the complexity of the routing of the orientation cords of the mirror blades.
Solution apportée par l'invention Solution provided by the invention
Afin de remédier à cet inconvénient, la présente invention concerne selon son acception la plus générale un store vénitien constitué par une pluralité de lamelles présentant chacune une face supérieure réfléchissante, lesdites lamelles étant orientables par pivotement entre une position où la normale à la surface réfléchissante est orientée verticalement vers le haut, et des positions où ladite normale à la surface réfléchissante est orientée vers l'intérieur, caractérisé en ce que chacune desdites lamelles étant prolongée à son bord extérieur par une bande s'étendant vers le bas, ladite bande présentant une largeur au moins égale à la hauteur séparant deux lamelles consécutives, le bord inférieur de chacune desdites bandes étant rigide et relié à un moyen de liaison vertical intérieur. In order to remedy this drawback, the present invention relates in its most general sense to a venetian blind consisting of a plurality of slats each having a reflecting upper face, said slats being orientable by pivoting between a position where the normal to the reflecting surface is oriented vertically upwards, and positions where said normal to the reflecting surface is oriented inwards, characterized in that each of said lamellae being extended at its edge exterior by a strip extending downwards, said strip having a width at least equal to the height separating two consecutive strips, the lower edge of each of said strips being rigid and connected to an interior vertical connection means.
On entend par « surface réfléchissante » au sens du présent brevet une surface opaque produisant une réflexion spéculaire dans le spectre visible dans une direction de réflexion unique, ou dans un faisceau de réflexion unique présentant un angle d'ouverture de moins de 20°. L'angle d'ouverture du faisceau de réflexion est mesuré à partir la direction médiane où la réflexion produit son intensité lumineuse maximale (le centre) jusqu'à la direction où la source lumineuse donne encore 50 % de lumière. Dans ce dernier cas, la lumière est réfléchie pour produire une lumière douce moins éblouissante que dans le cas d'une réflexion strictement spéculaire tout en concentrant l'essentiel de l'énergie incidente réfléchi dans la direction de la pièce. For the purposes of the present patent, the term “reflecting surface” means an opaque surface producing a specular reflection in the visible spectrum in a single direction of reflection, or in a single reflection beam having an opening angle of less than 20 °. The aperture angle of the reflection beam is measured from the middle direction where the reflection produces its maximum light intensity (the center) to the direction where the light source still gives 50% light. In the latter case, the light is reflected to produce a soft light that is less dazzling than in the case of strictly specular reflection while concentrating most of the incident energy reflected in the direction of the part.
Une surface peinte ou vernis ne sera pas considérée comme réfléchissante au sens du présent brevet, même lorsque le revêtement est brillant. A painted or varnished surface will not be considered reflective within the meaning of this patent, even when the coating is glossy.
Le bord intérieur des bandes est de facto rigide lorsque les bandes sont réalisés dans un matériau rigide. A défaut, si les bandes sont souples, leur bord est complété par une tige longitudinale rigide, par exemple une baguette coulissant dans un ourlet formé à la bordure de la bande. The inner edge of the bands is de facto rigid when the bands are made of a rigid material. Failing that, if the bands are flexible, their edge is completed by a rigid longitudinal rod, for example a rod sliding in a hem formed at the edge of the band.
Avantageusement, ledit moyen de liaison vertical intérieur relie également les bords intérieurs desdites lamelles. Advantageously, said interior vertical connecting means also connects the interior edges of said lamellae.
Selon une variante, ledit moyen de liaison intérieur est une cordelette guidée, notamment guidée verticalement. According to one variant, said internal connecting means is a guided cord, in particular guided vertically.
Selon une première variante, ladite bande est une bande souple. According to a first variant, said strip is a flexible strip.
Selon une deuxième variante, ladite bande est une bande rigide. Selon un premier mode de réalisation, ladite bande est une bande opaque : lorsque les lamelles sont en position verticales, le store est totalement occultant. According to a second variant, said strip is a rigid strip. According to a first embodiment, said strip is an opaque strip: when the slats are in a vertical position, the blind is completely blackout.
Selon un deuxième mode de réalisation, ladite bande est une bande translucide : lorsque les lamelles sont en position horizontales, le store laisse passer la lumière diffuse mais préserve l'intimité. According to a second embodiment, said strip is a translucent strip: when the slats are in a horizontal position, the blind lets diffused light through but preserves privacy.
Selon un troisième mode de réalisation, ladite bande est une bande transparente. According to a third embodiment, said strip is a transparent strip.
Selon une première alternative, les bords extérieurs et/ou les bords intérieurs de deux lamelles consécutives sont articulés par au moins une liaison rigide. Vu de côté, les lamelles et les liaisons forment alors un parallélogramme déformable formé par deux lamelles consécutives et les liaisons reliant les bords intérieurs consécutifs et extérieurs consécutifs. According to a first alternative, the outer edges and / or the inner edges of two consecutive lamellae are articulated by at least one rigid connection. Seen from the side, the lamellae and the links then form a deformable parallelogram formed by two consecutive lamellae and the links connecting the consecutive inner edges and consecutive outer edges.
Selon une seconde alternative, les bords extérieurs et/ou les bords intérieurs desdites lamelles sont articulés par au moins une liaison souple. According to a second alternative, the outer edges and / or the inner edges of said strips are articulated by at least one flexible connection.
Selon une variante particulière, la largeur desdites lamelles correspond à la distance séparant deux lamelles consécutives. Lorsque les lamelles sont basculées à 90°, elles opacifient totalement la fenêtre. According to a particular variant, the width of said slats corresponds to the distance separating two consecutive slats. When the slats are tilted 90 °, they completely opacify the window.

Description générale General description
Les figures 1 et 2 représentent un exemple de fenêtre constituée par un cadre (1) muni d'un vitrage transparent (2). Figures 1 and 2 show an example of a window consisting of a frame (1) provided with a transparent glazing (2).
Le store est constitué de lamelles (10 à 14) supportées par des cordelettes (45, 46). The blind consists of slats (10 to 14) supported by cords (45, 46).
Chaque lamelle présente une surface supérieure (5) réfléchissante renvoyant la lumière du soleil vers l'intérieur de la pièce. Le but est de donner une visibilité du ciel depuis une pièce, même lorsque la vision directe ne le permet pas. Each slat has a reflective upper surface (5) reflecting sunlight towards the interior of the room. The aim is to provide visibility of the sky from a room, even when direct vision does not allow it.
Le bord longitudinal extérieur de chaque lamelle (10 à 14) est prolongé par une bande (30 à 33), par exemple en tissu. Ces bandes souples (30 à 33) retombent verticalement pour occulter la vision directe, et protéger l'intimité, tout en se rapprochant du bord intérieur de la lamelle inférieure, permettant ainsi la pénétration de la lumière du soleil. Alternativement, ces bandes (30 à 33) peuvent être constituées de lamelles rigides articulées pour permettre un basculement par rapport au bord extérieur (20 à 24) de la lamelle (10 à 14) qu'elles prolongent. The outer longitudinal edge of each strip (10 to 14) is extended by a strip (30 to 33), for example made of fabric. These flexible bands (30 to 33) fall vertically to obscure direct vision, and protect privacy, while approaching the inner edge of the lower slat, allowing sunlight to penetrate. Alternatively, these bands (30 to 33) can consist of rigid hinged strips to allow tilting relative to the outer edge (20 to 24) of the strip (10 to 14) which they extend.
Ces bandes empêchent la vision dans la pièce depuis l'extérieur, depuis un point de vue situé au même niveau que l'ouverture. La vue est masquée d'une part par les lamelles opaques et miroitantes en alternance avec ces bandes opaques. These bands prevent vision into the room from outside, from a point of view at the same level as the opening. The view is masked on the one hand by the opaque and shimmering slats alternating with these opaque bands.
Les lamelles (10 à 14) munies d'un miroir sont orientables par un système constitué par un premier fil tendu (45) du côté de la fenêtre et un deuxième fil (46) coté pièce. The slats (10 to 14) provided with a mirror are adjustable by a system consisting of a first wire stretched (45) on the side of the window and a second wire (46) on the part side.
Chaque lamelle (10 à 14) présente à ses extrémités extérieures (vers la fenêtre) des tiges transversales. Each strip (10 to 14) has transverse rods at its outer ends (towards the window).
A chaque tige est fixée une bande souple (30 à 33) à laquelle est fixée une deuxième tige transversale à sa deuxième extrémité. Cette deuxième tige doit être assez lourde pour qu'il puisse glisser le long du fil intérieur. To each rod is fixed a flexible strip (30 to 33) to which is fixed a second rod transverse to its second end. This second rod should be heavy enough so that it can slide along the inner wire.
Les tiges coté fenêtre sont fixées à des hauteurs prédéterminées, avec un pas constant, sur le premier fil (45), avec un degré de liberté en pivotement. La tige extérieure peut aussi être fixée au miroir indépendamment du fil. The window side rods are fixed at predetermined heights, with a constant pitch, on the first wire (45), with a degree of freedom in pivoting. The outer rod can also be attached to the mirror independently of the wire.
Les tiges coté pièce sont positionnées devant (vers la pièce) le fil (46). The rods on the part side are positioned in front of (towards the part) the wire (46).
