  • the thermal insulation device thus makes it possible to obtain good thermal insulation with a simple implementation.
  • the figure 1 represents a partially exploded perspective view of a thermal insulation device according to the invention.
  • the thermal insulation device is intended to be installed in a building opening, for example between a window and a shutter.

  • the thermal insulation device comprises a thermally insulating mattress 1 fixed at its high end and foldable / unfoldable between a fully folded position, said folded position, and a completely unfolded position, said unfolded position.
  • a mattress height is defined in the vertical direction, a mattress width in a horizontal direction parallel to the window, and a mattress thickness in a horizontal direction perpendicular to the window.
  • the height of the mattress 1 varies.
  • the mattress 1 In the folded position, the mattress 1 is picked up near its fixed end. It has a low height, of the order of a few centimeters.
  • the mattress 1 In the unfolded position, the mattress 1 is deployed over the entire height of the window. On the figure 1 , the mattress is in the intermediate position between the folded position and the unfolded position.
  • the mattress 1 can indeed take a multitude of positions between the folded position and the unfolded position.
  • the mattress 1 comprises two outer walls 10.
  • the mattress 1 is disposed with its outer walls 10 parallel to the plane of the window.
  • the mattress 1 of the thermal insulation device further comprises internal partitioning means 11 formed between the outer walls 10. These internal partitioning means 11 preferably form a plurality of channels 12 of air parallel to each other.
  • the channels 12 are horizontal and parallel to the outer walls 10 of the mattress 1.
  • the channels 12 are fixed to each other, for example by welding or gluing.
  • the mattress 1 is thus formed of columns of channels 12 superimposed on each other, the columns being adjacent to each other.
  • the mattress 1 comprises at least three columns.
  • the mattress 1 comprises between four and seven columns. Indeed, the thicker the mattress, the better the thermal insulation.
  • the thickness of the mattress 1 is limited by the space between the window and the shutter. The number of columns therefore also depends on the dimensions of the section of the channels. Thus, if the cell section is particularly small or the mattress needs to be very thick for a specific application, for example to insulate an opening of a building with very low energy consumption, the mattress may comprise a larger number of columns, such as for example 10 or even 15 columns.
  • the section of the channels 12 of the mattress 1 is preferably small in order to limit air movements in the transverse direction of the channels and thus to avoid air convection movements in order to provide good thermal insulation.
  • the section of the channels 12 is for example between 0.2 and 5 cm 2 , preferably between 0.2 and 2 cm 2 .
  • the section of the channels is between 0.2 and 1 cm 2 , or even equal to 1 cm 2 .

  • external walls 10 are attached and fixed by welding or gluing on the channels 12.
  • the outer walls 10 are attached to the outer edges 25 ( Figure 3a, 3b , 8 and 14 )

  • the thickness of the mattress 1 is defined as the distance between the outer walls 10.
  • the thickness of the mattress 1 is defined as the distance between two vertical planes passing through the outer edges 25 of the mattress 1.
  • the walls of the channels 12 are for example airtight. They are open at their ends so that they can fill with air or empty when unfolding or folding the mattress. Air movements are limited inside the channels. The smaller the channel size, the smaller the air movement inside the channels. This structure of the mattress provides good thermal insulation, as explained above.
  • the walls of the channels 12 are made of an airtight material and have a plurality of microscopically sized perforations. These micro-perforations are additional air inlet or outlet means during folding / unfolding with respect to the openings at the ends of the channels. Folding / unfolding can then be done more quickly. Air movements in a direction transverse to the channels remain limited because of the microscopic size of the perforations.
  • an air injection system in the mattress can be provided to increase the folding / unfolding speed of the mattress.
  • the mattress 1 is waterproof because the mattress 1 is intended to be installed between a window and a shutter, or outside a building.
  • the mattress 1 (external walls 10 + internal partitioning means 11 / channels 12) is preferably made of plastic, for example polyethylene, polypropylene or PVC.
  • the mattress is made of woven material, of paper-based composite material, for example associated with protective layers, or of composite material based on polymers.
  • the channels 12 are low emissivity. They have, for example, an emissivity of less than 0.3 or of the order of 0.1.
  • the channels are for example metallized, that is to say covered with a metal layer inside the channels. This metal layer must be thin enough not to hinder the folding / unfolding of the mattress.
  • the metallized channels reduce the thermal conductivity of the mattress and thus increase the thermal resistance mattress, which improves the thermal insulation of a building opening in which the mattress is installed.
  • the lower the thermal conductivity of the mattress the higher the thermal resistance of the mattress and the better the thermal insulation.
  • the mattress 1 may be of flexible or rigid material.
  • the mattress 1 has a constant thickness over its entire height and width when it is in the unfolded position so that its thermal performance is good over its entire height and width.
  • the greater the thickness of the mattress the higher the thermal resistance of the mattress and the better the thermal insulation.
  • the thermal insulation device therefore comprises means for substantially constant maintenance of the thickness of the mattress in unfolded position over the entire height and the width of the mattress.
  • each channel 12 is for example formed of several rigid plates 24 adjacent to each other, the length of the width of the mattress, the rigid plates forming the longitudinal walls of the channel.
  • the rigid plates 24 are connected to each other by thin lines 27 ( Figures 5 and 6 ) or flexible hinge joints made of the same or different material plates, in particular of elastomer.
  • the walls of each channel have a plurality of folds forming hinges.
  • the term "hinges" should be understood as a general term encompassing these two exemplary embodiments.
  • the structure of the mattress does not allow it to have a constant thickness over the entire height and the width of the mattress.
  • the means for substantially constant maintenance of the thickness of the mattress in the unfolded position over the entire height and the width of the mattress may comprise rigid or tensioned guides on which slide connecting pieces fixed to the mattress.

  • the distance between respectively two rods, bars, wires or cables in each direction determines the distance between the rings and consequently between the free edges of the mattress in the corresponding direction, from one edge to the other of the same wall or between the edges of two opposite walls.
  • the rings 21 are for example each fixed at one end of a (one) second bar, rod, wire or cable 22 fixed on one of the outer walls 10 of the mattress 1, parallel to the channels (parallel to the board) and perpendicularly to the first four (first) rods, bars, wires or cables 10.
  • the second bars, rods, wires or cables 22 are fixed to the outer walls 10 of the mattress 1 for example by gluing.

  • the top of the mattress 1 is fixed to the trunk 2 and is not movable.
  • the thermal insulation device also comprises a movable board 3 fixed at the bottom of the mattress 1.
  • This board 3 is substantially horizontal. The rise / fall of the movable board 3 causes folding / unfolding of the mattress 1.
  • the movable board 3 is intended to abut against the trunk 2 to close the opening when the mattress is in the folded position (as on the Figures 3b, 4b ) and intended to abut against a lower surface such as a window sill when the mattress is in the unfolded position.
  • the movable board 3 has a mass sufficient to help unfold the mattress. Thus, if the actuation of the movable board 3 is manual, the movable board 3 helps the mattress to remain in the unfolded position, and thus promotes the maintenance substantially constant thickness of the mattress 1 over its entire height and width in unfolded position.
  • the movable board 3 is for example PVC, polymeric material, metal, composite material combining metal and a polymer, or wood.

  • This case makes it possible to dispense with additional parts (the nuts) but requires additional machining (tapping through holes).
  • the tapping can be carried on a nut incorporated in a plastic or composite board by overmolding.
  • the worms 7 are arranged in a vertical plane passing through the middle of the width of the movable board 3. However, they may also be offset with respect to this median plane, each of which may be arranged in a vertical plane located near an edge of the board that is parallel to the window, either the edge on the side of the window or the edge located on the flap side, as shown on the figure 11 or on the figure 15 on the same side of the insulation blanket. Alternatively, the worm 7 are arranged in a vertical plane located diagonally of the movable board 3, the worm being on one side and the other of the mattress.
  • a first solution to maintain the horizontal moving board 3 when the worm 7 are not arranged in a vertical plane passing through the middle of the width of the movable board 3, shown on the figure 15 is that the nuts 9 located above the movable board 3 and integral therewith serve as guiding means of the board 3 mobile.
