Description

The present invention relates to the general field of building insulation, particularly in the context of the use of a mobile type air conditioner or dryer.

More particularly, the invention relates to an isolation device intended to be positioned at an opening of a door or window type building.

The invention also relates to a method of installing an isolation device at an opening of a door or window type building.

The use of mobile air conditioners, that is to say an appliance able to cool a room by evacuating hot air without being fixed on the building, has become more and more common in recent years . Indeed, these mobile home appliances that is to say, transportable, are today at an affordable price and have many advantages that make them more and more chosen by consumers, especially in the face of an installation of fixed air conditioning. Indeed, these mobile devices do not require heavy work, at least no work comparable to a fixed air conditioning installation (laying ducts, installation of a condenser outside, installation of an evaporator in each room, etc. .), for a very good comfort / investment compromise.

These mobile air conditioners generally give satisfaction to their users, at least in terms of comfort, by allowing to reduce by several degrees the temperature of the room in which it is during hot summer periods.

Nevertheless, their use generally entails a significant energy loss and consequently an overconsumption of energy of the building. Indeed, like any air conditioner, these devices extract calories from the indoor air to refresh it. But these calories must be rejected outside the building, so are these devices equipped with a large diameter exhaust air hose intended to evacuate hot air. In other words, these devices have a pipe to be passed between the interior of the building (or more exactly between the room to be cooled) and the outside of the building.

For this purpose, two solutions are generally presented to the users. A first solution is to make a hole through the wall, a window or a door in order to pass the extraction pipe between the inside of the building and the outside. But, given the average diameter of the air extractor pipes of these devices (usually 125 mm), the realization of this hole is usually a complex operation, requiring the intervention of a professional (mason, glazier, carpenter, etc.. ) and that will generate structural, functional, and visual changes to the building. Therefore, many people, including tenants, can not undertake such work or do not wish to undertake such work. In addition, this hole is a break in the insulation of the building, (especially when it is made through a wall), so it is best to block the latter when the device is not used. In fact, outside the summer months, mobile air conditioner users will generally store the latter in their cellar or garage to free the room of this device that is no longer useful. Users will then be forced to plug the hole to find some insulation of their building, for example by means of a flange or other plug. But generally these last elements do not give satisfaction, in particular from the point of view of the insulation and their aestheticism.

But, given the complexity of the previous work and / or disadvantages mentioned above, the solution generally adopted by the users of these devices is simply to pass the extraction pipe through a window (or a door), which presupposes to leave this last ajar. But, leaving the window open, or at least sufficiently open to allow the passage of the extraction pipe, the user will allow the calories of the outside air warmer to return inside the building, even though the goal is to extract calories from the building's interior.

In addition to the hot air that enters the building, other undesirable elements can also penetrate inside the building through the open opening, such as rain, insects or pollen. It is therefore particularly uncomfortable, if not impossible, to use a mobile air conditioner when it rains, at night (on pain of seeing the insects invade the building's interior) or, for sensitive people, during pollination, because of the need to leave a window (or door) open to allow the passage of the extraction pipe.

Finally, other household appliances, such as dryers without condensers (called drain dryers), also need to expel hot air (and particularly wet in a dryer) ) externally and also include an air extractor pipe which has the same characteristics and disadvantages as the air extractor pipe of the mobile air conditioners described above. Therefore, all the drawbacks mentioned above also apply to the use of these devices, including in winter, for example when the hot and very humid air of the dryer must be expelled to the outside.

The objects assigned to the present invention therefore aim to remedy the various disadvantages listed above and to propose a new insulation device that can be positioned easily and quickly on different types of openings of a building (door or window type). and which is particularly easy to use, inexpensive while providing effective insulation.

The invention relates as such to an isolation device 1 and preferably to a thermal insulation device. In other words, the main function of the device which is the subject of the invention is advantageously to isolate one element with respect to another, and preferably at least from a thermal point of view. Nevertheless, said device 1 may advantageously also make it possible to produce other insulations, such as, for example, soundproofing, visual insulation, or insulation with respect to particles, such as dust, pollen, water or else insulation against insects.

According to the invention, said device 1 is intended to be positioned at an opening 2 of a building, that is to say that the device 1 is designed to be, during its normal use, on, in, or against an opening of a building. Preferably, said opening 2 is of the door or window or window-door type, and said building may equally well be an individual dwelling (for example a house), a collective dwelling (for example a building), a public building

(a school, a theater, a restaurant, etc.) or a professional building (workshop, garage, etc.).

Preferentially, and as illustrated in particular by Figures 1 to 4 said opening 2 is made through a wall 6 of said building, thus defining, in a manner well known as such, a table 21 and a lintel 22.

Alternatively, said opening 2 can also be made through the roof of a building, whether the latter is a flat roof (roof terrace type) or inclined roof (roof tile type), and can then for example constitute a window of roof.

Said opening 2 is preferably of rectangular shape, like most doors and windows that may comprise a building and its width W2 is preferably between 30 cm and 140 cm, while its height H2 is preferably between 40 cm and 250 cm. .

Particularly advantageously, said device 1 is intended to be positioned according to a so-called "table " installation mode, that is to say that the device 1 is positioned inside the table 21 (or the frame) said opening 2, for example a window. Although the device 1 can also be installed according to a so-called " frontage " installation mode, that is to say above said opening 2, it is the advantageous installation mode called " in table " which will be described below.

According to the invention, said device 1 comprises an insulation curtain 13, as illustrated by the various figures. By " insulation curtain" is preferably meant a movable element whose main function is to isolate a first space from another space, particularly and advantageously from a thermal point of view as specified above.

Still according to the invention, said curtain 13 itself comprises a flexible screen 131 (or a flexible blind) as can be seen for example on the figure 1 .

Preferably said flexible screen 131 is substantially rectangular in shape and may for example consist of a flexible material panel, flange, such as a fabric, or a tarpaulin of natural or synthetic material (PVC, preferentially coated fabric, etc.). . Advantageously, the thickness of said screen 131 is designed to give said screen 131 an excellent compromise between flexibility, mechanical strength and insulation, and may for example be between a few tens of microns and 1 mm.

It is also conceivable, without departing from the scope of the invention, that said flexible screen 131 is formed by a plurality of elementary blades having a certain rigidity, sufficient to configure them own mechanical strength, these elementary blades being articulated together, so as to confer a character generally flexible, flexible, said screen 113 thus obtained.

The dimensions of said screen 131 may advantageously be selected from a wide range, so as to allow said device 1 to be compatible with a plurality of different openings (ranging from a small window to a door, or even a door window). For example the width W131 of said screen 131 (which then corresponds substantially to the width of said curtain 13) is between 30 cm and 140 cm while its height is between 40 cm and 250 cm.

In the example illustrated in the figures, the flexible screen 131 is formed of a sheet of plastic material (for example transparent PVC) of substantially rectangular shape, the width of said sheet corresponding substantially to the width W2 of said opening 2 while that the length of said sheet corresponds for its part substantially to the height H2 of said opening 2.

Preferably, said flexible screen 131 forms a barrier to air, and / or advantageously to other elements such as, in an illustrative and nonlimiting manner, water, UV (ultraviolet rays), insects, to pollen, etc. Regardless, said screen 131 may be entirely transparent, that is to say that it can be seen through, opaque (that is to say that the light can pass through but without it being possible to see through), reflecting (like a mirror), tinged with a particular color or even occulting (the light does not pass through).

Preferably, said flexible screen 131 is sealed (or impermeable), for example in air or water, over at least 90% of its surface, providing an anti-reflux function to said isolation device 1, hot air and potentially wet evacuated by said exhaust pipe air can not pass through said screen 131 to return for example in the room of a house that is to be cooled, when said curtain 13 is in the deployed position. Preferably said flexible screen 131 is non-perforated and sealed (or impermeable) over its entire surface.

Advantageously, said screen 131 has two faces, an inner face intended to be oriented towards the interior of the building and an outer face intended to be oriented towards the outside, which include treatments and / or different appearances (es), as for example a UV treatment and mirror effect for the outer face while the inner face has no special treatment, which allows to see through said screen 131 from the inside out but not since the outside, thus ensuring a remarkable privacy function.

In other words, thanks to the different properties of said screen 131, it is possible for a user of the device 1 to benefit from a plurality of functions, such as, for example, enhanced thermal insulation (anti-UV treatment), visual isolation ( opaque treatment) while maintaining a good brightness (the light passes through the screen in question).

According to the invention, said device 1 comprises a passage 132 formed through said flexible screen 131, as illustrated in particular by the figure 1 . Advantageously, said passage 132 comprises a hole, a light or a notch made through said screen 131 so as to locally break the insulation of the latter.

Preferably, said passageway 132 comprises an orifice, advantageously formed through the flexible screen, preferably in the vicinity of a free end thereof, said orifice being of substantially circular cross section whose diameter is between 80 mm and 150 mm, and advantageously between 110 mm and 130 mm. Advantageously, the diameter of said passage 132 is adapted according to the standard diameters used by appliance manufacturers for the exhaust air hoses of the household appliances in question.

Preferably, said passage 132 is located in the vicinity (for example between 10 mm and 100 mm) of a lower corner of said screen 131 (the lower corners being the corners of said screen situated at the bottom when the latter is in a vertical position at the level of the opening 2), so as to be close to a lower angle of said opening 2. Advantageously, it is possible to choose the corner (right or left) near which said passage 132 is located by a reversal of the direction (inside / outside) of said screen 131.

Preferably, said curtain 13 comprises a reinforcement 133 disposed near said passage 132 and extending over the entire width of said screen 131 designed to increase locally (advantageously near said passage 132) the rigidity, and advantageously the transverse rigidity (this is that is to say, according to the width W131), of said flexible screen 131. Advantageously, said reinforcement 133 comprises a bar for example metallic attached to said screen 131 over the entire width W131 thereof. Preferably said reinforcement 133 comprises two bars intended to cooperate with each other to attach on either side of said screen 131, for example by means of clips, so as to " sandwich " said flexible screen 131 over its entire width, in order to increase its rigidity locally. In other words, said reinforcement 133 is embedded on the screen 131 and is an integral part of said curtain 13.

Although it is not mandatory in the insulation device 1 defined by the invention, said reinforcement 133 is particularly important when the width W131 of the flexible screen 131 is consistent, that is to say for example greater than at 50 cm. Preferably said reinforcement 133 is located a few centimeters (for example between 1 cm and 10 cm, and preferably 3 cm) above said passage 132.

Preferably, the length L133 of said reinforcement is substantially equal to the width W131 of said screen 131, as can be seen in FIG. figure 1 and the height H133 of said reinforcement 133 is substantially between 5 mm and 20 mm, while the thickness of said reinforcement 133 is advantageously less than 5 mm.

Advantageously, at least said curtain 13 is made of cuttable material (s) (for example aluminum, PVC, etc.) so as to be able to adjust substantially its dimensions to those of said opening 2. in other words, the various elements constituting said curtain 13, and in particular, said flexible screen 131 and possibly said reinforcement 133 are designed to be easily cut by the user so that their dimensions (more precisely the width W131 of said screen 131 and the length L133 of said reinforcement 133), correspond to the dimensions, and particularly to the width W2, with a slight operating clearance (advantageously less than 2 cm for example), of said opening 2 on which the user wishes to install said device 1 as shown in figure 1 . Preferably, said curtain 13 is designed to move between its deployed position and its retracted position by being deployed or retracted in at least one main extension direction, for example to fit a dimension of said opening 2 (in the embodiment shown in the figures, this dimension corresponds to the height H2 of said opening 2). Said curtain 13 (and preferably at least said screen 131) is advantageously made of material (s) cut (s) so as to substantially adjust its dimension in at least a direction substantially perpendicular to said main extension direction, for example according to the width W131 of said screen 131. Preferably, said screen 131 is flexible and designed to be folded or wound at least in said main extension direction.

According to the invention, said curtain 13 is designed to move between an extended position in which said curtain 13 closes said opening 2 so as to isolate the inside of the building from the outside and a retracted position in which said curtain 13 frees said opening 2. The figures 1 and 2 illustrate for example the curtain 13 in its deployed position, while the figures 3 and 4 illustrate for example the curtain 13 in retracted positions (more precisely, a retracted position and a fully retracted position, as will be detailed later).

• une première position visible notamment sur les figures 1 et 2, correspondant à ladite position déployée, qui correspond à une fermeture (ou une occultation), préférentiellement totale, de ladite ouverture 2, de manière à réaliser une isolation entre l'intérieur du bâtiment et l'extérieur, et
• une deuxième position visible notamment sur les figures 3 et 4, correspondant à ladite position rétractée, qui correspond à une libération (ou à une non fermeture, ou une non occultation), au moins partielle, de ladite ouverture 2, position selon laquelle ledit rideau 13 ne peut pas réaliser d'isolation entre l'intérieur du bâtiment et l'extérieur.

In other words, said curtain 13 is movable between at least two different positions:

• a first visible position especially on figures 1 and 2 corresponding to said deployed position, which corresponds to a closure (or occultation), preferably, of said opening 2, so as to provide insulation between the interior of the building and the outside, and
• a second position visible especially on figures 3 and 4 , corresponding to said retracted position, which corresponds to a release (or non-closure, or non-occultation), at least partial, of said opening 2, position in which said curtain 13 can not achieve insulation between the inside the building and outside.

Although this does not really have any advantage vis-à-vis the building insulation, it is quite possible to position said curtain 13 in an intermediate position between said deployed and retracted positions.

According to the invention, said passage 132 is designed to be connected to an exhaust pipe of a household appliance of the air conditioner or dryer type, or any other household appliance that would have an extraction pipe of air requiring blowing outside the building, as described above. The expression " connected to " is preferably used in the widest possible direction, that is to say that a connection between said passage 132 and said pipe may comprise, in an illustrative and nonlimiting manner, different types of connections. such as a slide link, a pivot or pivot-sliding connection, etc. or an interlocking or even a connection made by means of a particular socket or connection.

In other words, according to the invention, said passage 132 and said pipe of the appliance are intended to cooperate together. Preferably, said pipe passes through said screen 131 through said passage 132. Advantageously, said passage 132 performs a guiding function and preferably maintaining said pipe for example by preventing the latter from moving. Said passage 132 then preferably constitutes a housing for said pipe of the household appliance within said screen 131.

According to the invention, said passage 132 and said pipe are connected together when the curtain 13 is deployed so as to allow the evacuation of air out of the building while preserving the insulation. In other words, when the curtain 13 is in the deployed position, that is to say in the position in which it closes said opening 2, it is particularly advantageous to connect said passage 132 and said pipe between them, so as to preserve the building insulation, while allowing auditing appliance to extract the air outside the building. Conversely, although it is possible, there is no real interest in connecting these previous elements when the curtain 13 is in its retracted position to the extent that the building is no longer isolated from the outside. . This connection is then remarkably optimized (if not made possible) by the presence of said reinforcement 133 described above, which, by locally improving the rigidity of the flexible screen 131, makes it possible to hold said pipe in place and to prevent the latter from deforming the flexible screen 131.

Preferably, said device 1 further comprises a drum 113 around which said curtain 13 is intended to wind when it is in the retracted position. Advantageously, said drum 113 comprises a hollow bar, and preferentially a tube as can be seen on the figure 5 whose length L113 is substantially equal to the width W131 of said screen 131 and whose outer diameter is substantially between 10 mm and 80 mm.

According to this preferred embodiment, said drum 113 is rotatably mounted about a substantially horizontal axis of rotation X-X ', or at least parallel to the lintel 22 of said opening 2.

Preferably, the flexible screen 131 extends between a first edge attached to said drum 113 and a second free edge. Said first edge of the screen 131 is advantageously fixed, preferably over its entire width W131 (for example by a method known as gluing, folding, sewing, etc.), to the drum 113, so as to be able to wind said screen 131 around the drum 113 by rotation of the latter around its axis of rotation X-X ', and conversely to unwind said screen 131, that is to say, to unwind the drum 113, as illustrated for example the Figures 2 to 4 .

In other words, when said curtain 13 is in its retracted position, said screen 131 is mostly wound around said drum 113, so that a multitude of thicknesses of said screen 131 are around said drum 113, such as illustrate the figures 3 and 4 . Conversely, when said curtain 13 is in its deployed position, said screen 131 is mainly unrolled, so that there are only a few thicknesses of screens 131 around said drum 113, as shown in FIG. figure 2 .

Advantageously, the drum 113 is equipped with a return spring 114, which is preferably a torsion spring advantageously situated inside said drum 113, this return spring 114 making it possible to permanently constrain the drum 113 so as to subject the flexible screen 131, via its first edge attached to the drum 113, to an elastic restoring force (in this case an elastic return torque) thus advantageously avoiding the formation of folds on said screen 131.

In this case, the unwinding of said curtain 13 is effected against the return bias exerted permanently by the drum 113 on the screen 131, by means of the aforementioned return spring 114, the drum 133 optionally comprises advantageously a locking means (not shown in the figures) to maintain said curtain 13 in its deployed position. In a manner known per se, such a locking means may for example comprise a free wheel, or any other system with ratchets and / or pawls, which allows on the one hand to unroll and wind said screen 131 and to block it to will.

Of course, the use of a rotary drum 113 is absolutely not mandatory, and it is quite possible to use alternative means. For example, it is possible to use a system for folding the flexible screen 131 on itself, for example accordion, instead of wrapping around a rotating drum.

According to an advantageous embodiment, said drum 113 is rotatably mounted in a box 11, as illustrated for example by Figures 2 to 5 . Preferably, said box 11 is intended to be positioned under the lintel 22 of said opening 2, for example by means of different fixing holes 116, as illustrated in FIG. figure 5 .

Advantageously, said box 11 comprises a main casing 111 for example of substantially parallelepiped shape inside which the various elements previously described, and in particular, the drum 113, the spring 114, and the curtain 13 when it is in its retracted position, can be accommodated (or stored).

Preferably said main casing 111 comprises a slot 117 advantageously made along its entire length as illustrated by FIG. figure 5 designed to allow passage of said curtain 13 through said housing 111 and thereby allow it to wind around said drum 113.

The length L11 of said box 11 is substantially equal to, or at least slightly greater than a few millimeters, the width W131 of said screen 131, and also substantially corresponds to the width W2 of said opening 2. Preferably the profile of the box 11 is substantially a square whose side is substantially of a dimension between 10 cm and 30 cm, thus defining its height H11. Advantageously, the dimension of this side is less than or equal to the thickness T21 of table 21 of said opening 2 so as not to exceed the latter and therefore not to exceed the thickness of the wall 6 of the building, when said device 1 is posited " in a table ". This feature thus allows the user to be able to use the various elements, namely for example the window 3 and the flap 4, of its opening 2, even in the presence of the device 1, as illustrated, for example, by the Figures 2 to 4 .

Preferably, said box 11 also comprises lateral flanges 112a, 112b intended to close said main casing 111. Advantageously, said flanges 112a, 112b comprise rotational guiding elements 118 (for example lugs, housings, bearings, etc. .) so as to constitute the axis of rotation XX 'of said drum 113, for example being designed to penetrate inside the drum 113.

In the preferred case where said curtain 13 comprises a reinforcement 133 as defined above, said box 11 is advantageously designed to accommodate said reinforcement 133 when said curtain 13 is in its retracted position, as can be seen in the drawings. figures 3 and 4 . In particular, the slot 117 is then advantageously designed to allow the passage of said reinforcement 133.

Particularly advantageously, the box 11 is made of cuttable material (s) (for example aluminum, PVC, etc.) so as to be able to adjust its dimensions to those of said opening 2. In other words, the different elements constituting said box 11, and in particular, said main housing 111 and said drum 113 are designed to be easily cut by the user so that their dimensions, and particularly their respective lengths L11, L113, correspond to the dimensions, and particularly to the width W2 of said opening 2 on which the user wishes to install said device 1. Preferably, said return spring 114 is positioned so as not to be cut, for example at an end of said drum 113, said end being then advantageously identified, for example by means of a marking, such as an end not to be cut.

Preferably, only one of the two lateral flanges 112a, 112b can be dismounted (for example by means of screws), so as to be able to adjust the length L11 of said box 11 according to the advantageous manner previously described, the flange 112b being situated on the side of said non-cutting end being fixed.

Preferably, said box 11 comprises a first box seal (not shown in the figures), which advantageously comprises a brush seal extending over the entire length L11 of said box 11, intended to be positioned between said box 11 and said curtain 13 so as to provide a barrier (to air, water, insects or other particles) and thus optimize the insulation of said device 1. Advantageously said first boot seal is attached to said slot 117 so as to prevent air and / or water and / or any other element to penetrate inside said housing 111.

Preferably, said box 11 comprises a second box seal (not shown in the figures), which advantageously comprises a lip seal extending over the entire length L11 of said box 11, intended to be positioned between said box 11 and the lintel 22 in order to achieve a barrier (to air, water, insects or other particles) and thus optimize the effectiveness of the insulation of said device 1.

Preferably, said device 1 further comprises a guide path 12a, 12b intended to be attached to said opening 2, and preferably to the table 21 thereof, and preferably to the vertical and parallel portions of said table 21, as illustrated for example the Figures 2 to 4 . Preferably, said guide path 12a, 12b is attached, or fixed, to said opening 2 removably, by example using known fastening means, such as screws and dowels, advantageously in such a way as not to interfere with the hinges 5 which generally equip the opening 2. In other words, said guide path 12a, 12b is stationary and can thus constitute a frame or a frame of said isolation device 1.

More specifically, said guide path 12a, 12b is designed to guide said curtain 13 between its deployed position and its retracted position. In other words, said curtain 13 and said guide path 12a, 12b constitute a mechanical connection for imparting a movement to said curtain 13 while said guide path 12a, 12b is fixed. Preferably, the connection thus formed between these two elements is a link of the slide type, that is to say that said curtain 13 is able to slide or slide inside or around the guide path 12a, 12b, as the show the different figures. Preferably the movement carried out by said curtain 13 within said fixed guide path 12a, 12b is a vertical translation.

Thus, the various elements included in said curtain 13, and in particular the flexible screen 131 and the reinforcement 133, are designed to move along said guide path 12a, 12b as the deployment or retraction of the curtain 13, when the latter moves between its deployed and retracted positions defined above.

Advantageously, said guide path 12a, 12b is at least partially covered with a material intended to limit friction, such as for example polytetrafluoroethylene (PTFE), so as to facilitate the movement of said curtain 13.

Advantageously, the length L12 of the guide path 12a, 12b is of the same order of magnitude as the height H2 of the opening 2, and is, in the preferred case where the device 1 comprises a box 11 as defined above, substantially equal to at the height H2 of said opening 2 minus the height H11 of said box 11.

Preferably, said guide path 12a, 12b comprises two parallel and opposite elements intended to be each attached to each of the vertical portions of the table 21 of the opening 2.

Preferably, the guide path 12a, 12b, or at least one of its elements 12a, 12b is situated in the vicinity (for example between 10 mm and 100 mm and advantageously at 50 mm) of said passage 132, so as to guarantee the rigidity of said flexible screen 131 when said pipe passes therethrough.

According to a preferred embodiment and illustrated by the various figures, the guide path 12a, 12b comprises two opposite and parallel hollow rails (or slides, or slides) within which is intended to slide said curtain 13, said rails being designed to be attached to the table 21 of said opening 2, for example by means of screws and dowels and a plurality of fixing holes 122 made in said rails, as can be seen in the figure 7 . Advantageously, said rails are U-shaped profiles (for example in aluminum), said curtain 13 then being able to slide easily inside the latter, in particular in order to guarantee, on the one hand, its maintenance and on the other hand its good Wrap around said drum 113. The width W12 of each of said rails is then for example between 5 mm and 40 mm while the depth D12 is for example between 5 mm and 40 mm, so as to ensure a good compromise between guide said curtain 13 and facilitate the movement of the latter. Advantageously, said screen 131 and said reinforcement 133 are designed to slide inside said rails, and particularly inside the U of the latter.

Preferably, said rails comprise a fixing slot 122 and advantageously a plurality of fastening slots 122 regularly distributed over the entire length L12 of said rails, as can be seen on FIG. figure 7 , so as to make it possible to fix these in table 21 of the opening 2.

Preferably, and advantageously in the case where the drum 113 is not already equipped, said guide path 12a, 12b comprises a locking means for blocking the movement of said curtain 13, for example to prevent the latter from winding automatically by the effect of the spring 114. Said locking means may for example comprise a locking pin 123, as can be seen on the Figures 7 and 8 and which requires the user to make a horizontal pulling movement to release said curtain 13 so that it can move to its retracted position.

In the preferred case or said device 1 comprises a box 11, the latter advantageously comprises an assembly means 115 intended to cooperate with said guide path 12a, 12b, so as to make said box 11 and said guide path 12ab integral, 12b. Preferably, said assembly means 115 is a means designed to allow a temporary assembly, that is to say, dismountable between said box 11 and said guide path 12a, 12b, and is advantageously integrated with said lateral flanges 112a, 112b, as we can see on the figure 5 . Therefore, and according to the preferred embodiment represented by the various figures, said assembly means 115 may comprise two assembly blades each integrated with one of the lateral flanges 112a, 112b and intended to be inserted inside said hollow rails defined above, which allows an assembly between the trunk 11 and the guide path 12a, 12b removable, reliable, fast and easy.

According to the previous preferred embodiment comprising rails, said device 1 comprises rail seals 121 intended to be respectively interposed between each rail and said curtain 13, said seals 121 being in particular designed to form a barrier, in particular to water, air or other elements (insects, dust, etc.). For example, said seals 121 may comprise joints called brush seals which comprise a plurality of bristles, thus enabling them to provide a barrier against various elements (including air) while being flexible and deformable to guarantee and facilitate the movement of said curtain 13 inside said rails, as can be seen for example on the Figures 7 and 8 . Preferably each hollow rail comprises a pair of rail joints attached to each of the main uprights of said hollow rails, as can be seen in the figures mentioned above.

This embodiment is then also remarkably advantageous in the case where the curtain 13 comprises a reinforcement 133 as defined above. Indeed, said reinforcement 133 can easily evolve, along with said screen 131, within said rails, and the flexibility of said brush seals can remarkably ensure a good seal, by deforming locally around said reinforcement 13.

Particularly advantageously, the guide path 12a, 12b is made of cuttable material (s) (for example aluminum, PVC, rubber, bristles, etc.) so as to be able to adjust its dimensions to those of said opening 2. In other words, the various elements constituting said guide path 12a, 12b, and in particular, said rails and their rail joints 121 respective are designed to be easily cut by the user so that their dimensions, and particularly their respective lengths L12, correspond to the dimensions, and particularly to the height H2 of said opening 2 on which the user wishes to install said device 1. It will naturally be necessary for the user to reduce the length L12 of said guide path 12a, 12b of the height value H11 of said box if the device 1 has one, as can be seen in the various figures. Preferably, a plurality of fastener lumens 122 regularly distributed within said rails makes it possible to guarantee a possibility of fastening them to the board 21 regardless of the length L12 of said rails.

Naturally, in the preferred embodiment illustrated by the various figures, the width W131 of said screen 131 (which corresponds, in the embodiment illustrated in the figures, substantially to the width of said curtain 13) is adjusted substantially (advantageously during cutting of the latter) to the width W2 of the opening 2 minus the thickness of said guide path 12a, 12b, as shown in the various figures. More specifically, in the case where the guide path 12a, 12b comprises rails, the thickness of the latter is deduced from the width W2 of the opening.

Advantageously, said device 1 comprises a sleeve 15 designed to be connected on the one hand with said passage 132 and on the other hand with said discharge pipe, and designed to maintain and / or guide said pipe through of said flexible screen 131. Advantageously, said sleeve 15 is also designed to protect the curtain 13 from the heat emitted by the air extractor pipe, and thus constitutes a thermal insulator between said pipe and said curtain 13.

Preferably said sleeve 15 comprises a tube, for example a rigid PVC tube whose diameter is selected from the standard diameters used by the manufacturers of household appliances mentioned above, for example 125 mm. More specifically, the inside diameter of said tube is designed to allow the passage of said air extractor pipe, while the outside diameter of said tube is designed to correspond to the diameter of said passage 132.

Preferably, the thickness of said tube is less than 5 mm and its length L15 is between 15 mm and 75 mm and is advantageously equal to 50 mm.

Preferably, said sleeve 15 is positioned in such a way that its length L15 is equally distributed on either side of the screen 131, as can be seen on the figures 2 and 3 .

Advantageously, the length L15 of said sleeve 15 is determined or adjusted to be less than the thickness T21 of table 21 of said opening 2 and is advantageously less than or equal to the width of said box 11, so as not to exceed the table 21 and therefore the thickness of the wall 6 of the building. This feature thus allows the user to be able to use normally the various openings, namely for example the window 3 and the flap 4, its opening 2, and this even in the presence of the device 1 as illustrated for example by Figures 2 to 4 . According to this particularly advantageous embodiment, said device is therefore located inside the table 21 of the opening 2, so as to be interposed between the different openings (the window 3 and the flap 4) of said opening 2. said device 1 is then protected from the weather while allowing normal use of the opening 2 and its openings. In other words, said isolation device 1 is in this embodiment designed to be mounted "in" said opening 2, so that it is possible, regardless of the position of said curtain 13 (deployed or retracted, or even partially deployed / retracted), to close at least one opening associated with the frame of said opening 2, for example a window, a door or a flap.

Particularly advantageously, said sleeve 15 is removable, that is to say it can at will be assembled or disassembled said passage 132. This feature allows the curtain 13 remarkable feature of being able to be fully wound around the drum 113 , and advantageously be fully understood inside the trunk 11 when said curtain 13 is in its retracted position, as illustrated for example by the figure 4 . Such an arrangement of the device 1 will then be particularly useful for the user, for example when the latter seeks to benefit from a maximum clearance of its opening 2 (for example to pass bulky objects) or when he knows that he will not use isolation device 1 during a significant period of time (for example the winter period in the case of use with a mobile air conditioner).

Conversely, when the user does not need to benefit from a maximum clearance of its opening 2, or when he knows that he will soon need to redeploy the device 1, he can perfectly leave in place the sleeve 15 and wind the curtain 13 around the drum 113. The device 1 is then in a retracted position which is not total, as illustrated by FIG. figure 3 , to the extent that said sleeve 15 can not enter inside the box 11. This configuration is for example particularly useful for the user when the latter is absent from home or when the user wishes to ventilate his home . Indeed, in both cases, the user will have to disconnect and then quickly reconnect the air extractor pipe of his air conditioner, before either closing the window (to limit the risk of burglary during the absence of the user) or to wind the curtain 13 (when it wishes to ventilate the room for a few moments), so that it is preferable for it to leave the sleeve 15 in place.

Preferably, in the retracted position, and more particularly in the partially retracted position, said curtain 13 releases, in particular when said sleeve 15 is left in place, at least 60% of said opening 2, more preferably at least 70% of said opening 2 , more preferably at least 80% of said opening 2, and still more preferably at least 90% of said opening 2. For example, and as shown in FIG. figure 3 , said opening 2 released 90% by said curtain 13 may correspond to a configuration where said screen 131 is wound at 90% around said drum 113 inside said box 11, said passage 132 (connected or not with said sleeve 15) being then located near the upper part of the table of said opening 2, in the case where the insulating device 1 is disposed in said table 21 (or embrasure) of said opening 2, where said passage 132 is formed through the flexible screen 131 at the bottom of said screen 131 (more precisely in the lowest 10% of said screen 131, in the case where the screen is unrolled vertically). Preferably, said curtain 13 is designed to move between a fully deployed position where it constitutes the only movable element completely closing said opening 2, with the exception of said passage 132, and a partially retracted position in which said curtain 13 releases at least 80 %, even more preferentially less than 90% of said opening 2, or a fully retracted position in which said curtain 13 substantially releases the entire opening.

Preferably said sleeve 15 comprises a grid, such as for example a mosquito net, arranged radially inside said sleeve 15 so as to prevent insects from penetrating inside said pipe through the passage 132 made within said curtain 13.

Preferably said sleeve 15 comprises a non-return valve disposed inside said sleeve 15 so as to prevent outside air (but also rain, dust and other pollen) from penetrating inside said pipe when the latter is when stopped, that is to say evacuated by air, thus optimizing the thermal insulation of the device 1.

Preferably, said device 1 further comprises a base 14 attached to a free end of said flexible screen 131 which is preferably over the entire width W131 of said screen 131. The length L14 of said base 14 is substantially equal to the width W131 of said flexible screen 131. Advantageously, said base 14 is constituted by a bar, said load bar, for example metal (preferably aluminum), preferably of rectangular section.

Preferably, said base 14 is intended to interact punctually with said locking means, and advantageously with said locking pin 123, as illustrated in FIGS. figures 1 and 2 , so as to maintain the position of said curtain 13 in its extended position or, on the contrary, not to interact with said locking means, as illustrated in FIGS. figures 3 and 4 to allow the movement of said curtain 13, for example so that the latter can return to its retracted position. According to the preferred embodiment illustrated for example in Figures 7 and 8 , where said rails each comprise a locking pin 123, it is then necessary to exert a horizontal traction, for example preferably towards the interior of the building to allow said base 14 to no longer be in contact with said locking pin 123, and thus allow the winding of said curtain 13, in particular under the effect of the return spring 114.

Advantageously, said base 14 is attached to said flexible screen 131 by means of a fixing ring 144 around which said free end of the flexible screen 131 is wound, and which is inserted into an assembly groove 143 included in said base 14, as shown in figure 6 . More specifically, the shape and the positioning of said groove 143, for example made of dovetail, allows to insert (preferably by sliding from the side edge) said assembly rod 144 and said flexible screen 131 to the inside of said groove 143, while offering the assembly thus produced a high mechanical strength to traction.

Preferably said base 14 is located near said passage 132 (for example between 10 mm and 80 mm of said passage 132, and preferably substantially 30 mm below the latter), so as to guarantee the rigidity of said flexible screen 131 when said pipe passes through it.

Preferably said base is designed to slide along or around or inside said guide path 12a, 12b, as can be seen for example on the Figures 1 to 4 . According to the preferred embodiment where the guide path 12a, 12b comprises U-shaped rails, said base 14 is then designed to slide inside the U, for example by having pins (or brackets, not shown). in the guiding figures) located at the ends of said base 14, or being of a thickness less than the size of said U, then allowing it to be inserted at least partially inside said rail.

According to the preferred embodiment shown in the figures, said passage 132 is formed between said base 14 and said reinforcement 133, so as to be located in an area where the flexibility of the screen 131 is reduced by the presence of these elements. Thus maintaining and / or guiding said pipe are optimized.

Preferably, said base 14 comprises a base gasket 141 intended to come into contact with the table 21 of the opening 2, and more specifically with the lower horizontal part of said panel 21, or particularly advantageously with the support plate. of said opening 2, so as to offer the isolation device 1 an excellent seal, as illustrated for example by the figures 1 and 2 .

Advantageously, said base gasket 141 comprises a lip seal and / or a brush seal which extends over the entire length L14 of said base 14.

Advantageously, said base 14 comprises a gripping element 142 designed so that a user can maneuver said curtain 13 in order to move it between its deployed position and its retracted position, or vice versa between its retracted position and its deployed position. Preferably, said gripping member 142 comprises one or more of the following elements: a handle, a maneuvering rope, a lug, etc. According to the preferred embodiment illustrated by the figures, said gripping member 142 is constituted by two oblong hollow handles located on either side of a maneuvering rope. Thus, it is easy for a user to grip said base 14 in order to move said curtain 13 (preferably to move it between its deployed position and its retracted position, or reciprocally).

More specifically, oblong hollow handles will advantageously be used when the curtain 13 is in its deployed position and that the user wishes to move it to its folded position (that is to say when the curtain 13 is at the bottom and when the user wants to go up, for example to release said opening 2). The maneuvering rope will be advantageously used when the curtain 13 is in its retracted position and the user wishes to move it to its deployed position (that is to say when the curtain 13 is at the top and that the user wishes to lower it, and thus conceal said opening 2, for example to be able to install the air extractor pipe of his air conditioner), insofar as the latter allows to be enterable by the user even if the base 14 is unreachable.

Preferably the height H14 of said base 14 is sufficient to allow said base 14 to comprise at least one gripping element 142, the assembly rod 144 and the base gasket 141 defined above, as illustrated for example by the figure 6 . Thus said height H14 is for example between 10 mm and 50 mm.

Particularly advantageously, the base 14 is made of material (x) cuttable (s) (for example aluminum, PVC, rubber, etc.) so as to adjust its dimensions to those of said opening 2 In other words, the various elements constituting said base 14, and in particular its joint 141 and its assembly ring 144 are designed to be easily cut by the user so that their dimensions, and particularly their respective lengths. L14, L144, correspond substantially to the dimensions, and particularly to the width W2 (minus the thickness of said guide path 12a, 12b and with a slight functional clearance), said opening 2 on which the user wishes to install said device In other words, the length L14 of the base 14 is advantageously adjusted to the width W131 of said screen 131.

According to the preferred embodiment where the device 1 comprises a box 11, the latter is advantageously designed to accommodate, at least partially, said base 14 when the curtain 13 is in the retracted position and when the sleeve 15 is not present , as can be seen on the figure 4 . Thus, this feature makes it possible to free up said opening 2 when the user does not wish to use the device 1. In addition, the curtain 13 is then completely retracted inside the trunk 11 and said base 14 is also less partially, the discretion of the device 1 is improved in that only the trunk 11 and the guide path 12a, 12b remain visible.

Preferably, said base 14 is designed to be able partially, but not totally, to be retracted inside the trunk 11, so as to be at least partially invisible while nevertheless allowing the user to grasp the gripping element 142 which must not be hidden inside the trunk 11 to ensure future redeployment of the curtain 13.

The various elements described above thus make it possible to propose a simple insulating device 1, which relies on reliable, standard and inexpensive mechanical components (essentially a cover, tubes, profiles, bars, etc.) and which makes it possible to provide good thermal insulation, when it is desired to pass an extractor pipe of an appliance (for example a mobile air conditioner, or a dryer without a condenser) through an opening 2 (by example, a window), since, in summer, the warm air from the outside can not get inside the room cooled by the air conditioner, while in winter, the cold air does not can not go inside the room where the dryer is located, said isolation device 1 providing a barrier, while allowing the passage of said pipe.

In other words, the product makes it possible to use a mobile air conditioner in summer, without major work (masonry, glassware, etc.) normally required to allow the passage of the extraction pipe of the device. in a thermally isolated manner. It allows the use of the device by opening a window to pass the extraction pipe while thermally insulating the interior of the room (or is the air conditioner) from the outside. The isolation device 1 is partially removable (for example being rollable) which allows to find all the features of the window when the device 1 is not used.
