Abstract

1. A blind with vertical strips, characterised in that each strip consists of a sandwich formed by a central layer (1) having a thickness of from about 3 to 10 mm, made up of a very porous material with open cells and having excellent phonic absorption qualities, and by two layers (2) attached on either side of the central layer and consisting of an aerated material.

Description

La présente invention concerne les stores à bandes verticales et, plus particulièrement,un nouveau matériau composite apte à constituer les bandes verticales de tels stores et susceptible de répondre beaucoup mieux que les stores actuellement disponibles sur le marché, notamment aux contraintes exigeantes, en particulier sur les plans phonique et thermique, posées par les enceintes ou studios d'enregistrement, de salles de spectacle ou de concert etc...The present invention relates to blinds with vertical strips and, more particularly, to a new composite material capable of constituting the vertical strips of such blinds and capable of responding much better than the blinds currently available on the market, in particular to the demanding constraints, in particular on the phonic and thermal plans, posed by the speakers or studios of recording, of halls of performance or concert etc ...

De tels locaux nécessitent des conditions de correction accoustique, d'isolation phonique et d'isolation thermique qui imposent des aménagements adéquats des surfaces intérieures et notamment des ouvertures sur l'extérieur telles que les baies vitrées lorsqu'elles existent.Such premises require conditions of acoustic correction, sound insulation and thermal insulation which impose adequate arrangements of the interior surfaces and in particular openings to the outside such as the bay windows when they exist.

Il faut, en effet, munir ces vitrages, côté intérieur, d'un élément mobile permettant à volonté d'occulter la lumière, d'isoler des bruits extérieurs, de corriger l'accoustique du local et de l'isoler thermiquement.It is necessary, in fact, to provide these glazings, on the interior side, with a mobile element allowing at will to obscure the light, to isolate external noises, to correct the acoustics of the room and to insulate it thermally.

Les stores à bandes verticales actuels utilisés souvent à cette fin ne remplissent malheureusement pas toutes ces conditions, car la structure des bandes n'est pas spécifiquement étudiée pour satisfaire au mieux toutes les conditions imposées dans cette application particulière.The current vertical strip blinds often used for this purpose unfortunately do not meet all these conditions, since the structure of the strips is not specifically designed to best meet all the conditions imposed in this particular application.

La présente invention a précisément pour but de proposer une nouvelle structure de bande pour stores à bandes verticales susceptible de répondre efficacement aux différentes contraintes rencontrées dans les locaux du type ci-dessus et pourvues de baies vitrées ouvrant sur l'extérieur.The object of the present invention is precisely to propose a new strip structure for blinds with vertical strips capable of effectively responding to the various constraints encountered in premises of the above type and provided with bay windows opening onto the outside.

A cet effet, l'invention a pour objet une bande pour stores à bandes verticales caractérisée en ce qu'elle est constituée d'un sandwich formé d'une couche centrale d'épaisseur comprise entre environ 3 mm et environ 10mm réalisée en un matériau très poreux, à cellules ouvertes et ayant d'excellentes qualités d'absorption phonique et de deux couches rapportées de part et d'autre de la couche centrale et constituée d'un tissu aéré ou film plastique.To this end, the subject of the invention is a strip for blinds with vertical strips, characterized in that it consists of a sandwich formed by a central layer of thickness between approximately 3 mm and approximately 10 mm made of a material very porous, with open cells and having excellent sound absorption qualities and two layers added on either side of the central layer and made of an airy fabric or plastic film.

Le matériau constitutif de la couche centrale est, par exemple, une mousse de matière plastique telle que le polyuréthane, mais il pourrait être un molleton ou une ouate à base de fibres synthétiques ou naturelles, par exemple fibres minérales contenues sous enveloppe.The material constituting the central layer is, for example, a plastic foam such as polyurethane, but it could be a fleece or a wadding based on synthetic or natural fibers, for example mineral fibers contained in an envelope.

Quant au tissu aéré de part et d'autre de la couche centrale, il est avantageusement constitué par un tissu tissé ou à mailles.As for the ventilated fabric on either side of the central layer, it is advantageously constituted by a woven or mesh fabric.

D'autres caractéristiques et avantages ressortiront de la description qui va suivre d'un mode de réalisation de la structure selon l'invention, description donnée à titre d'exemple uniquement et en regard du dessin annexé sur sur lequel :

  • - Fig. 1 représente une vue en coupe partielle de la structure d'une bande pour stores à bandes verticales selon l'invention, et
  • - Fig. 2 représente une bande selon l'invention pourvue d'une lisière de finition sur ses tranches verticales.
Other characteristics and advantages will emerge from the description which follows of an embodiment of the structure according to the invention, description given by way of example only and with reference to the appended drawing in which:
  • - Fig. 1 shows a partial sectional view of the structure of a strip for blinds with vertical strips according to the invention, and
  • - Fig. 2 shows a strip according to the invention provided with a finishing edge on its vertical edges.

La structure du matériau composite selon l'invention est illustrée par la Fig. 1.The structure of the composite material according to the invention is illustrated in FIG. 1.

Cette structure en sandwich comprend une couche centrale 1, d'une épaisseur par exemple comprise entre 3 mm environ et une dizaine de millimètres.This sandwich structure comprises a central layer 1, with a thickness for example of between approximately 3 mm and ten millimeters.

La couche 1 est en un matériau très poreux, à cellules ouvertes, et ayant d'excellentes qualités d'absorption phonique. Ce matériau est avantageusement une mousse de matière plastique telle le polyuréthane. Ce peut être également un molleton ou une ouate à base de fibres synthétiques ou naturelles, des fibres minérales par exemple contenues sous enveloppe.Layer 1 is made of a very porous material, with open cells, and having excellent sound absorption qualities. This material is advantageously a plastic foam such as polyurethane. It can also be a fleece or a wadding based on synthetic or natural fibers, mineral fibers for example contained in an envelope.

La couche centrale 1 est prise en sandwich entre deux couches 2 en tissu aéré d'épaisseur généralement identique et nettement inférieure à celle de la couche 1.The central layer 1 is sandwiched between two layers 2 of aerated fabric of generally identical thickness and clearly less than that of layer 1.

Le matériau des couches 2 est de préférence un tissu tissé ou à mailles.The material of the layers 2 is preferably a woven or mesh fabric.

Les fonctions essentielles des couches 2 sont de laisser passer les sons, tout en protégeant la matière absorbante 1 et décorant la bande en lui conférant une certaine rigidité suffisante pour assurer une manoeuvre aisée des stores sans empêcher l'enroulement des bandes.The essential functions of the layers 2 are to let the sounds pass, while protecting the absorbent material 1 and decorating the strip by giving it a certain rigidity sufficient to ensure easy operation of the blinds without preventing the strips from being rolled up.

Cette relative rigidité est également assurée par le collage ou thermocollage des couches 2 sur la couche centrale 1, bien que la solidarisation des couches entre elles puisse être assurée par d'autres moyens que le collage.This relative rigidity is also ensured by the bonding or heat-bonding of the layers 2 on the central layer 1, although the joining of the layers together can be ensured by other means than bonding.

Par ailleurs, les matériaux constitutifs des couches 1 et 2 sont choisis de façon que les bandes soient ininflammables.Furthermore, the constituent materials of layers 1 and 2 are chosen so that the strips are non-flammable.

Afin d'assurer une meilleure finition des bandes, le long de leurs flancs verticaux, on prévoit avantageusement une sorte de liseré ou ganse rapporté sur chaque tranche verticale.In order to ensure a better finish of the strips, along their vertical flanks, provision is advantageously made for a sort of border or strap attached to each vertical edge.

La Fig. 2 illustre une telle finition à l'aide d'un profilé 3 en matière plastique fixé par exemple par couture sur le bord des deux couches externes 2. Ce profilé pourrait être remplacé par une bande de tissu ou de matière plastique, autocollante par exemple.Fig. 2 illustrates such a finish using a plastic profile 3 fixed for example by sewing on the edge of the two outer layers 2. This profile could be replaced by a strip of fabric or plastic, self-adhesive for example.

Chaque bande est suspendue au rail du store notamment à l'aide de deux barettes transversales (non représentées.) clipsées de part et d'autre sur la bande à son extrémité supérieure.Each strip is suspended from the blind rail, in particular using two transverse bars (not shown.) Clipped on either side on the strip at its upper end.

A leur partie inférieure., les bandes'comportent, à la manière bien connue, chacune un lest et sont reliées entre elles par des chaînettes.At their lower part., The bands have, in the well-known manner, each a ballast and are connected together by chains.

Les modes de montage et d'emploi des stores équipés de bandes verticales conformes à l'invention sont strictement identiques à ceux des stores traditionnels de ce type.The methods of mounting and using blinds fitted with vertical strips in accordance with the invention are strictly identical to those of traditional blinds of this type.

Les stores munis de bandes selon l'invention assurent à la fois une excellente absorption des bruits venant de l'extérieur et une très bonne atténuation de rêver- bération à l'intérieur du local ainsi équipé, aussi bien en position jour qu'en position nuit, sans nuire à l'esthétique puisque les bandes sont réversibles. Ils procurent, en outre, une bonne isolation thermique.The blinds provided with strips according to the invention ensure both excellent absorption of noise coming from the outside and very good attenuation of dreams. beration inside the room thus equipped, both in the day and in the night position, without harming the aesthetics since the bands are reversible. They also provide good thermal insulation.

Les stores à bandes verticales conformes à l'invention sont particulièrement recommandés non seulement pour l'équipement de locaux dont il a été question plus haut mais, plus généralement,.des lieux de réunion, salles polyvalentes, bureaux paysagés, locaux informatiques, salles de conférence, de classe, ainsi que des logements individuels.The vertical strip blinds in accordance with the invention are particularly recommended not only for equipping premises mentioned above but, more generally, meeting places, multipurpose rooms, landscaped offices, computer rooms, meeting rooms. conference, class, as well as individual accommodation.

Enfin, l'invention n'est évidemment pas limitée aux modes de réalisation représentés et décrits ci-dessus, mais en couvre au contraire toutes les variantes, notamment en ce qui concerne la nature des matériaux constitutifs des différentes couches ainsi que les dimensions de ces dernières. C'est ainsi que les couches 2 pourraient être constituées, au lieu d'un tissu, d'un film de matière plastique, soit très mince, soit perforé, faisant office de protection transparente au son.Finally, the invention is obviously not limited to the embodiments shown and described above, but on the contrary covers all the variants thereof, in particular as regards the nature of the materials constituting the different layers as well as the dimensions of these past. This is how the layers 2 could be made, instead of a fabric, of a plastic film, either very thin or perforated, acting as a transparent sound protection.
