Definitions

  • 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 recording studios, of rooms of. show or concert etc ...
  • 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.
  • 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.
  • each strip consists of a sandwich formed by a central layer of thickness between approximately 3 and 10 mm made of a very porous material, with open cells and having excellent sound absorption qualities and two layers added on either side of the central layer and consisting of an airy fabric or plastic film.
  • the constituent material of the central layer is, for example, a plastic foam such as polyurethane, then it could be a fleece or a wadding based on synthetic or natural fibers, for example mineral fibers contained in an envelope.
  • the ventilated fabric on either side of the central layer it is advantageously constituted by a woven or mesh fabric.
  • FIG. 1 The structure of the composite material according to the invention is illustrated in FIG. 1.
  • This sandwich structure comprises a central layer 1, with a thickness for example of between 3 and ten millimeters.
  • 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.
  • the central layer 1 is sandwiched between two layers 2 of ventilated fabric of generally identical thickness and clearly less than that of layer 1.
  • the material of the layers 2 is preferably a woven or mesh fabric.
  • 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.
  • constituent materials of layers 1 and 2 are chosen so that the strips are non-flammable.
  • 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.
  • 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.
  • the bands comprise, in the well-known manner, each a ballast and are connected together by chains.
  • the blinds provided with strips according to the invention ensure both excellent absorption of noise coming from the outside and very good attenuation of reverberation inside the room thus equipped, both in the day position and in the night position, without affecting the aesthetics since the bands are reversible. They also provide good thermal insulation.
  • Vertical blinds in accordance with the invention are particularly recommended not only for equipping rooms with We mentioned above but, more generally, meeting rooms, multipurpose rooms, landscaped offices, computer rooms, conference rooms, classrooms, as well as individual accommodation.
