Definitions

  • the present invention relates to the general field of rolling shutters contained in a trunk. More specifically, it relates to a roller shutter box assembly, the box of which has increased sound insulation.
  • Roller shutters comprise, in a conventional manner, a prefabricated box containing a winding shaft, not shown, resting by its ends on bearings integral with the end flanges of said box and to which is hung an apron, not shown, formed of blades horizontal hinged together and whose ends move vertically inside guide rails, not shown, secured to a window of a building associated with the roller shutter or the masonry of the building surrounding said window.
  • an apron not shown, formed of blades horizontal hinged together and whose ends move vertically inside guide rails, not shown, secured to a window of a building associated with the roller shutter or the masonry of the building surrounding said window.
  • roller shutter is very efficient from a mechanical and kinematic point of view, but has the disadvantage of being relatively noisy, particularly at the level of the trunk, the major part of which is arranged inside the building. Indeed, during renovation work on the windows of a building, the box of each roller shutter, which is usually pre-assembled in the factory and made by assembling polyvinyl chloride (PVC) boards or panels, advantageously double-walled, cannot not be integrated into the masonry and is therefore protruding inside the building against the masonry.
  • PVC polyvinyl chloride
  • DE 202 11 717 U1 discloses a box attached to the masonry of the window opening, U-shaped open on the lower side, formed by two L-shaped structures which overlap and are glued together on the top.
  • the side walls of said box are essentially hollow plastic panels with mitered ends.
  • AT 4 092 U1 discloses an essentially U-shaped box profile, in particular for roller shutter boxes, intended to reduce the transport volume and therefore the transport costs and to guarantee perfect adhesion of the plaster to the outer face of the profile box without additional measures.
  • This box profile consists of several plastic box profile elements having at least one chamber.
  • the object of the present invention is to reinforce the overall acoustic performance of a roller shutter box by proposing a variant of a board of a box that is easy to implement in said box and makes it possible to increase the acoustic insulation of the latter. , while guaranteeing good mechanical strength of this box, which is mounted cantilevered on the upper frame of a window.
  • an acoustic box for a rolling shutter comprising at least rear, upper, front and lower boards each comprising at least one internal wall, an external wall and a plurality of cells extending longitudinally between said internal and external walls, said box being remarkable in that the majority of the cells of at least the upper and lower boards have a cross-section in the shape of a circle, or of a hexagon and/or of a pentagon having at least one side inclined with respect to the associated internal and/or external wall(s) or of a closed hybrid line composed of a combination of circle and d a hexagon or pentagon.
  • the cells have sections of different sizes and shapes.
  • the back, top, front and bottom boards are advantageously made of polyvinyl chloride.
  • FIG. 1 there is shown a box 1 for roller shutter according to the prior art made from an assembly of longitudinal boards 2,3,4,5 and two end plates, not shown, said end plates and boards 2,3,4,5 being conventionally double walls made of polyvinyl chloride (PVC).
  • PVC polyvinyl chloride
  • a box 10 for roller shutter similar to the box 1 of the prior art described above and also made from an assembly of two end plates, not shown, and longitudinal boards, namely a rear board 11 located on the side of the masonry or window associated with the roller shutter, an upper board 12, a front board 13, and a lower board 14, said end flanges and boards being conventionally made of polyvinyl chloride (PVC).
  • PVC polyvinyl chloride
  • the trunk 10 according to the invention differs from that of the prior art in that the rear 11, upper 12, front 13 and lower 14 boards are double walls each comprising at least one internal wall 11a, 12a, 13a , 14a, an outer wall 11b, 12b, 13b, 14b and a plurality of cells 11c, 12c, 13c, 14c extending longitudinally between said inner 11a, 12a, 13a, 14a and outer 11b, 12b, 13b, 14b walls .
  • the cells 11c, 12c, 13c, 14c of at least one of the rear 11, upper 12, front 13 and lower 14 boards have a cross section in the shape of a closed curve, of a polygon having at least one side inclined with respect to the wall internal 11a, 12a, 13a, 14a and/or external 11b, 12b, 13b, 14b associated (s) or closed hybrid line composed of an association of a curve and a polygon.
  • inclined with respect to the associated internal and/or external wall designates here the fact that the cross section of each cell comprises at least one side which is not parallel or not perpendicular to the associated internal and/or external wall or to the portion of the associated internal and/or external wall located close to said cell, in the case of an internal and/or external wall that is not entirely planar.
  • the cells 11c, 12c, 13c, 14c advantageously have sections of different sizes and shapes.
  • the upper 12 and lower 14 boards comprise a majority of cells 12c, 14c in the shape of a hexagon and a pentagon.
  • the lower board 14′ comprises a majority of cells 14c′ in the shape of a circle.
  • the other boards of the trunk 10' may also include a majority of cells in the shape of a circle.
  • major here denotes the fact that the cells in the shape of a hexagon, a pentagon or a circle represent the largest set of cells among all the cells of the board(s) of the trunk 10, 10'.
  • the trunk 10 finds a particular application for containing a rolling shutter of a window.
