Description

Domaine techniqueTechnical area

La présente invention concerne un dispositif anti-bruit adapté pour guider et maintenir les lamelles d'un store à lamelles. En particulier le dispositif anti-bruit est conçu pour atténuer ou supprimer le bruit résultant des mouvements du store par rapport aux rails de guidage. L'invention concerne également un ensemble comprenant de tels dispositifs anti-bruit et un store à lamelles.The present invention relates to an anti-noise device suitable for guiding and maintaining the slats of a slatted blind. In particular, the anti-noise device is designed to attenuate or eliminate the noise resulting from the movements of the blind relative to the guide rails. The invention also relates to an assembly comprising such anti-noise devices and a slatted blind.

Etat de la techniqueState of the art

Les stores à lamelles, également connus sous la dénomination de stores vénitiens, comportent des lamelles fines et légères qui battent facilement contre les surfaces avoisinantes. En particulier, dans le cas où les stores à lamelles sont utilisés en extérieur, le vent peut faire battre les lamelles contre les rails utilisés pour les maintenir en place. Le bruit qui en résulte peut être désagréable et parfois gênant.Slat blinds, also known as Venetian blinds, feature thin, light slats that easily beat against surrounding surfaces. In particular, in the event that slatted blinds are used outdoors, the wind can cause the slats to beat against the rails used to hold them in place. The resulting noise can be unpleasant and sometimes annoying.

Il est cependant indispensable de laisser une tolérance entre les lamelles du store et les rails de glissement de sorte que les lamelles puissent facilement coulisser de haut en bas et de bas en haut. En particulier, considérant le poids très léger de telles lamelles, les moindres frottements risqueraient d'entraver leur descente lors de la fermeture du store.However, it is essential to leave a tolerance between the slats of the blind and the sliding rails so that the slats can easily slide up and down and up and down. In particular, considering the very light weight of such slats, the slightest friction could hinder their descent when closing the blind.

Il est donc nécessaire de développer des solutions qui permettent à la fois de manipuler le store à lamelles avec aisance et de limiter voire éliminer les bruits résultant de l'agitation du store.It is therefore necessary to develop solutions which make it possible both to handle the slatted blind with ease and to limit or even eliminate the noises resulting from the agitation of the blind.

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

La figure 4 donne un exemple de rail de guidage habituellement utilisé pour des lames de store. Les lèvres S1 et S2 permettant de maintenir les lamelles dans un tel rail sont en matière dure et génère un bruit qui peut être désagréable lors du battement des lamelles, une fois le store abaissé.The figure 4 gives an example of a guide rail usually used for blind slats. The lips S1 and S2 making it possible to hold the slats in such a rail are made of a hard material and generates a noise which can be unpleasant when the slats are beating, once the blind has been lowered.

Le dispositif anti-bruit 1 selon la présente invention est représenté en détails dans les figures 2, 3 et 7. Il se présente sous la forme d'un profilé, comprenant une surface externe 14 et une surface interne 15 et une ouverture 16 disposée sur l'une de ses faces et qui s'étend sur toute sa longueur. Les autres faces du dispositif anti-bruit 1 comprennent deux faces latérales 17a, 17b et une face dorsale 18. Le dispositif anti-bruit 1 forme ainsi un guide longitudinal dont la section est en forme de U ou approximativement en forme de U, dans lequel peuvent glisser des guide-lamelles 4, solidaire des lamelles 2, selon un axe de glissement X. En d'autres termes, l'espace intérieur Ei du dispositif anti-bruit 1 est l'espace délimité par les deux faces latérales 17a,17b et la face dorsale 18. The anti-noise device 1 according to the present invention is shown in detail in the figures 2 , 3 and 7 . It is in the form of a section, comprising an external surface 14 and an internal surface 15 and an opening 16 arranged on one of its faces and which extends over its entire length. The other faces of the anti-noise device 1 comprise two side faces 17a, 17b and a dorsal face 18. The anti-noise device 1 thus forms a longitudinal guide, the section of which is U-shaped or approximately U-shaped, in which The slat guides 4, integral with the slats 2, can slide along a sliding axis X. In other words, the interior space Ei of the anti-noise device 1 is the space delimited by the two side faces 17a, 17b and the dorsal surface 18.

La surface externe 14 du dispositif anti-bruit 1 comporte sur ses faces latérales 17a, 17b un relief longitudinal tel qu'une rainure 10a, 10b ou une lèvre 11a, 11b, ou une combinaison des deux, permettant de s'imbriquer dans un relief complémentaire d'un rail 3 fixé sur un support. Le support est en l'occurrence le mur délimitant l'ouverture du bâtiment à laquelle le store à lamelles est destiné. Le rail 3 est de préférence un profilé métallique fixé à la paroi et permettant de maintenir les lames du store à lamelles dans l'axe de la descente et de la remontée du store à lamelles, correspondant à l'axe de glissement X. À cet effet il est orienté verticalement sur les côtés de l'ouverture du bâtiment, qui peut être une fenêtre ou une porte. Le rail 3 comporte sur ses surfaces internes le relief complémentaire de celui du dispositif anti-bruit 1. Les rainures 10a, 10b ou les lèvres 11a, 11b ou l'ensemble des deux permet ainsi de maintenir le dispositif anti-bruit 1 dans l'évidement du rail 3. The external surface 14 of the anti-noise device 1 comprises on its lateral faces 17a, 17b a longitudinal relief such as a groove 10a, 10b or a lip 11a, 11b, or a combination of the two, making it possible to fit into a relief complementary to a rail 3 fixed on a support. The support is in this case the wall delimiting the opening of the building for which the slatted blind is intended. The rail 3 is preferably a metal section fixed to the wall and making it possible to maintain the slats of the slatted blind in the axis of the descent and of the rise of the slat blind, corresponding to the sliding axis X. To this end indeed it is oriented vertically on the sides of the building opening, which can be a window or a door. The rail 3 comprises on its internal surfaces the relief complementary to that of the anti-noise device 1. The grooves 10a, 10b or the lips 11a, 11b or the combination of the two thus makes it possible to maintain the anti-noise device 1 in the recess of the rail 3.

La surface interne du dispositif anti-bruit 1 comporte à l'extrémité de chacune de ses faces latérales 17a, 17b une lèvre de glissement 12a, 12b orientée vers l'espace intérieur du dispositif anti-bruit 1. Les lèvres de glissement 12a, 12b encadrent ainsi l'ouverture longitudinale 16 du dispositif anti-bruit 1. Les lèvres de glissement 12a, 12b forment un angle A par rapport au plan passant par les axes transversal Z et longitudinal X du dispositif anti-bruit 1 compris entre 10° et 90°, de préférence entre 30° et 50°, comme représenté plus spécifiquement dans la figure 2. Elles sont de préférence symétriques par rapport au plan passant par les axes transversal Z et longitudinal X. De préférence la section du dispositif anti-bruit 1 est totalement symétrique par rapport au plan passant par les axes transversal Z et longitudinal X. Cependant, selon certaines dispositions, la section du dispositif anti-bruit 1 peut ne pas être totalement symétrique. Les faces latérales 17a et 17b peuvent par exemple être orientées différemment l'une de l'autre par rapport au plan passant par les axes transversal Z et longitudinal X. Il est précisé que les axes longitudinal X et transversal Z sont perpendiculaires l'un par rapport à l'autre. Un axe transversal Z s'entend comme tout axe perpendiculaire à l'axe longitudinal X et passant par le milieu de l'ouverture 16 du dispositif anti-bruit 1. The internal surface of the anti-noise device 1 comprises at the end of each of its lateral faces 17a, 17b a sliding lip 12a, 12b oriented towards the interior space of the anti-noise device 1. The sliding lips 12a, 12b thus frame the longitudinal opening 16 of the anti-noise device 1. The sliding lips 12a, 12b form an angle A with respect to the plane passing through the transverse Z and longitudinal X axes of the anti-noise device 1 between 10 ° and 90 ° °, preferably between 30 ° and 50 °, as shown more specifically in the figure 2 . They are preferably symmetrical with respect to the plane passing through the transverse Z and longitudinal X axes. Preferably the section of the anti-noise device 1 is completely symmetrical with respect to the plane passing through the transverse Z and longitudinal X axes. However, according to some provisions, the section of the anti-noise device 1 may not be completely symmetrical. The side faces 17a and 17b can for example be oriented differently from one another with respect to the plane passing through the transverse Z and longitudinal X axes. It is specified that the longitudinal X and transverse Z axes are perpendicular to each other. compared to each other. A transverse axis Z is understood to be any axis perpendicular to the longitudinal axis X and passing through the middle of the opening 16 of the anti-noise device 1.

Les lèvres de glissement 12a, 12b sont chacune pourvues d'un revêtement 13a, 13b faisant office de surface de glissement et d'amortissement pour les lamelles 2 du store à lamelles. Le revêtement 13a, 13b est disposé sur la surface externe des lèvres de glissement 12a, 12b et est destiné à être en contact avec les lamelles 2 du store à lamelles. La figure 7 montre le détail du revêtement 13a, 13b des lèvres de glissement 12a, 12b. Le revêtement 13a, 13b comporte une partie 131a, 131b associée aux lèvres de glissement 12a, 12b et une extrémité libre 130a, 130b dirigée vers l'intérieur du dispositif anti-bruit 1. L'extrémité libre 130a, 130b du revêtement 13a, 13b est flexible de sorte à amortir les mouvements des guide-lamelles 4 par rapport au dispositif anti-bruit 1. L'ouverture 16 ainsi ménagée dans le dispositif anti-bruit 1 a une largeur L constante sur toute la longueur du dispositif anti-bruit 1. The sliding lips 12a, 12b are each provided with a coating 13a, 13b acting as a sliding and damping surface for the slats 2 of the slat blind. The coating 13a, 13b is disposed on the outer surface of the sliding lips 12a, 12b and is intended to be in contact with the slats 2 of the slat blind. The figure 7 shows the detail of the coating 13a, 13b of the sliding lips 12a, 12b. The coating 13a, 13b comprises a part 131a, 131b associated with the sliding lips 12a, 12b and a free end 130a, 130b directed towards the inside of the noise- canceling device 1. The free end 130a, 130b of the coating 13a, 13b is flexible so as to damp the movements of the slat guides 4 with respect to the anti-noise device 1. The opening 16 thus provided in the anti-noise device 1 has a constant width L over the entire length of the anti-noise device 1.

Le dispositif anti-bruit 1 est de préférence en matériaux souple, néanmoins suffisamment rigide pour être maintenu dans un rail 3. Il peut être constitué par exemple en polymère synthétique,The anti-noise device 1 is preferably made of flexible materials, nevertheless sufficiently rigid to be held in a rail 3. It can be made, for example, of synthetic polymer,

Les lamelles 2 sont illustrées plus en détails dans les figures 5 et 6. Elles comportent chacune un corps de lamelle 23 destiné à protéger l'ouverture du bâtiment une fois le store abaissé. Le corps de lamelles 23 peut comprendre des points de connexion 22a, 22b permettant de relier les lamelles 2 du store à lamelles entre elles ou à un dispositif de traction 21a, 21b. Un tel dispositif de traction 21a, 21b peut prendre la forme de sangles permettant le glissement des lamelles 2 le long du dispositif anti-bruit 1 pour occulter ou libérer l'ouverture du bâtiment, ou leur rotation selon l'axe transversal Z, de sorte à moduler la luminosité à l'intérieur du bâtiment une fois le store à lamelles abaissé. Le corps des lamelles 23 est orienté selon un axe transversal Z, perpendiculaire à l'axe de glissement X. Les lamelles 2 peuvent avoir une surface plane ou courbée. Elles peuvent par exemple être bombées, concaves, convexes, ou en forme de vague.The slats 2 are illustrated in more detail in the figures 5 and 6 . They each comprise a slat body 23 intended to protect the opening of the building once the blind has been lowered. The slat body 23 may include connection points 22a, 22b making it possible to connect the slats 2 of the slat blind to each other or to a traction device 21a, 21b. Such a traction device 21a, 21b can take the form of straps allowing the slats 2 to slide along the anti-noise device 1 to obscure or release the opening of the building, or their rotation along the transverse axis Z, so to modulate the light inside the building once the slatted blind is lowered. The body of the slats 23 is oriented along a transverse axis Z, perpendicular to the sliding axis X. The slats 2 can have a flat or curved surface. They can for example be curved, concave, convex, or wave-shaped.

Chaque extrémité des lamelles 2 est pourvue d'un guide-lamelle 4, permettant de maintenir les lamelles 2 en position, lorsque le store à lamelles est abaissé. Les guides-lamelles 4 comportent à cet effet un moyen de fixation 41 destinée à assurer leur cohésion avec les lamelles 2. Un tel moyen de fixation 41 peut par exemple prendre la forme de deux surfaces 410a, 410b faisant office de pince et disposées de part et d'autre de l'épaisseur de la lamelle 2 correspondante. Les surfaces 410a, 410b peuvent être soudées ou collées à la lamelle 2. D'autres moyens de fixation peuvent être considérés, notamment en fonction de la forme géométrique des lamelles 2. Les guide-lamelles 4 sont disposés de manière symétrique aux deux extrémités de chaque lamelle 2, de sorte à créer un axe de rotation pour la lamelle 2 correspondante selon un axe transversal Z. Chaque guide-lamelle 4 comporte en outre une tête 42 reliée au moyen de fixation 41 par un pivot 43. Le pivot 43 est d'épaisseur réduite par rapport à la tête 42 de sorte à s'inscrire dans l'ouverture longitudinale 16 du dispositif anti-bruit 1 correspondant. Les lèvres de glissement 12a, 12b des dispositifs anti-bruit 1 encadrent le pivot 43 du guide-lamelle 4. En particulier, l'extrémité libre 130a, 130b des revêtements 13a, 13b est à proximité ou au contact du pivot 43. Les mouvements des lamelles 2 par rapport aux guide-lames 1 est ainsi amortit par les extrémités libres 130a, 130b des revêtements 13a, 13b. Le revêtement 13a, 13b est à cet effet suffisamment souple pour amortir les battements des lamelles 2 dans les dispositifs anti-bruit 1. Il est par exemple constitué d'un polymère synthétique ou naturel ou un mélange de polymères. Le revêtement 13a, 13b peut être apposé sur la surface des lèvres de glissement 12a, 12b par un procédé de surmoulage ou par tout autre moyen connu de l'homme de métier.Each end of the slats 2 is provided with a slat guide 4, making it possible to keep the slats 2 in position, when the slat blind is lowered. The lamella guides 4 comprise for this purpose a fixing means 41 intended to ensure their cohesion with the lamellae 2. Such fixing means 41 can for example take the form of two surfaces 410a, 410b acting as a clamp and arranged on either side. and the other of the thickness of the corresponding strip 2. The surfaces 410a, 410b can be welded or glued to the lamella 2. Other fixing means can be considered, in particular depending on the geometric shape of the lamellae 2. The lamella guides 4 are arranged symmetrically at the two ends of the lamellae. each lamella 2, so as to create an axis of rotation for the corresponding lamella 2 along a transverse axis Z. Each lamella guide 4 further comprises a head 42 connected to the fixing means 41 by a pivot 43. The pivot 43 is of reduced thickness compared to the head 42 so as to fit into the longitudinal opening 16 of the corresponding anti-noise device 1. The sliding lips 12a, 12b of the anti-noise devices 1 frame the pivot 43 of the lamella guide 4. In particular, the free end 130a, 130b of the coverings 13a, 13b is near or in contact with the pivot 43. The movements of the strips 2 relative to the blade guides 1 is thus damped by the free ends 130a, 130b of the coverings 13a, 13b. The coating 13a, 13b is for this purpose sufficiently flexible to dampen the beating of the slats 2 in the noise-canceling devices 1. It is for example made of a synthetic or natural polymer or a mixture of polymers. The coating 13a, 13b can be affixed to the surface of the sliding lips 12a, 12b by an overmolding process or by any other means known to those skilled in the art.

La tête 42 des guide-lamelles 4 est retenue dans l'espace interne des dispositifs anti-bruit 1. Elle peut comporter à cet effet deux ailes 420a, 420b aptes à s'insérer derrière les lèvres de glissement 12a, 12b des dispositifs anti-bruit 1. Avantageusement, une rotation du guide-lamelle 4 de 90° selon l'axe transversal Z permet d'en dégager les ailes 420a, 420b du dispositif anti-bruit 1. Une telle rotation est possible grâce au pivot 4, dont le diamètre d est toujours inférieur, quelle que soit son orientation angulaire, à la largeur L de l'ouverture 16 du dispositif anti-bruit 1. Le pivot 43 permet ainsi une orientation angulaire des lamelles 2 selon un axe transversal Z. La tête 42 a une dimension maximale D, inférieure à la largeur interne L' du dispositif anti-bruit 1. Sa dimension minimale est avantageusement inférieure à la largeur L de l'ouverture 16. The head 42 of the lamella guides 4 is retained in the internal space of the anti-noise devices 1. For this purpose, it may comprise two wings 420a, 420b capable of being inserted behind the sliding lips 12a, 12b of the anti-noise devices. noise 1. Advantageously, a rotation of the lamella guide 4 by 90 ° along the transverse axis Z allows the wings 420a, 420b of the anti-noise device to be released therefrom 1. Such a rotation is possible thanks to the pivot 4, the diameter d is always less, regardless of its angular orientation, than the width L of the opening 16 of the noise reduction device 1. The pivot 43 thus allows angular orientation of the slats 2 along a transverse axis Z. The head 42 has a maximum dimension D, less than the internal width L ' of the anti-noise device 1. Its minimum dimension is advantageously less than the width L of the opening 16.

Selon un mode de réalisation avantageux, le revêtement 13a, 13b dépasse des lèvres de glissement 12a, 12b de sorte à pouvoir amortir les mouvements latéraux des lamelles 2 en s'appuyant sur les surfaces internes des ailes 420a, 420b. En d'autres termes, la partie libre 130a, 130b du revêtement pénètre dans l'espace intérieur Ei du dispositif anti-bruit 1 sur une distance TR supérieure à la distance TL de pénétration des lèvres de glissement 12a, 12b. L'angle A d'inclinaison des lèvres de glissement 12a, 12b, par rapport à un axe transversal Z et la longueur des extrémité libres 130a, 130b du revêtement 13a, 13b sont donc déterminés de sorte à ce que la distance de pénétration TR du revêtement 13a, 13b dans l'espace intérieur Ei soit supérieure à la distance de pénétration TL des lèvres de glissement 12a, 12b, compte tenu de l'épaisseur de ces lèvres de glissement 12a, 12b. According to an advantageous embodiment, the coating 13a, 13b protrudes from the sliding lips 12a, 12b so as to be able to damp the lateral movements of the blades 2 by resting on the internal surfaces of the wings 420a, 420b. In other words, the free part 130a, 130b of the coating penetrates into the interior space Ei of the anti-noise device 1 over a distance TR greater than the distance TL of penetration of the sliding lips 12a, 12b. The angle A of inclination of the sliding lips 12a, 12b, with respect to a transverse axis Z and the length of the free ends 130a, 130b of the coating 13a, 13b are therefore determined so that the penetration distance TR of the coating 13a, 13b in the interior space Ei is greater than the penetration distance TL of the sliding lips 12a, 12b, taking into account the 'thickness of these sliding lips 12a, 12b.

Selon un mode de réalisation, le revêtement 13a, 13b, comporte une protrusion 132a, 132b qui recouvre la surface extérieure du dispositif anti-bruit 1, de part et d'autre de l'ouverture longitudinale 16. Ainsi, le revêtement 13a, 13b permet d'amortir les chocs entre le moyen de fixation 41 du guide lame 4 et le dispositif anti-bruit 1. De préférence, le revêtement produit une surépaisseur par rapport à la surface extérieure du rail 3. Les mouvements latéraux des lamelles 2 sont ainsi amortis grâces aux protrusions 132a, 132b du revêtement 13a, 13b. According to one embodiment, the coating 13a, 13b comprises a protrusion 132a, 132b which covers the outer surface of the noise- canceling device 1, on either side of the longitudinal opening 16. Thus, the coating 13a, 13b makes it possible to absorb the shocks between the fixing means 41 of the blade guide 4 and the anti-noise device 1. Preferably, the coating produces an extra thickness with respect to the outer surface of the rail 3. The lateral movements of the blades 2 are thus cushioned thanks to the protrusions 132a, 132b of the coating 13a, 13b.

La présente invention couvre en outre un procédé d'installation d'un dispositif anti-bruit 1. Le procédé comprend une première étape de fixation des rails 3 sur les parois de l'ouverture d'un bâtiment. Les rails 3 sont installés verticalement sur les côtés de l'ouverture de sorte à procurer un guidage selon l'axe de glissement X des lamelles 2 du store à lamelles. La surface interne des rails 3 comporte un relief rectiligne et longitudinal permettant de glisser le dispositif anti-bruit 1. The present invention further covers a method of installing an anti-noise device 1. The method comprises a first step of fixing the rails 3 on the walls of the opening of a building. The rails 3 are installed vertically on the sides of the opening so as to provide guidance along the sliding axis X of the slats 2 of the slatted blind. The internal surface of the rails 3 has a rectilinear and longitudinal relief allowing the anti-noise device 1 to slide.

Le procédé comporte une seconde étape d'installation du dispositif anti-bruit 1 dans chacun des rails 3. A cet effet, chaque dispositif anti-bruit 1 est inséré à l'une des extrémités des rails 3 de sorte à faire coïncider les reliefs extérieurs 10a, 10b, 11a, 11b, du dispositif anti-bruit 1 avec les reliefs internes des rails 3. Le dispositif anti-bruit est ensuite coulissé sur la longueur du rail 3 correspondant au moins à la distance de déploiement des lamelles 2. The method comprises a second step of installing the anti-noise device 1 in each of the rails 3. For this purpose, each anti-noise device 1 is inserted at one of the ends of the rails 3 so as to make the external reliefs coincide. 10a, 10b, 11a, 11b, of the anti-noise device 1 with the internal reliefs of the rails 3. The anti-noise device is then slid along the length of the rail 3 corresponding at least to the deployment distance of the slats 2.

Les lamelles 2 peuvent ensuite être insérées dans le dispositif anti-bruit 1 par leurs extrémités, grâce notamment aux guide-lamelles 4. The slats 2 can then be inserted into the anti-noise device 1 by their ends, thanks in particular to the slat guides 4.
