Description

DOMAINE TECHNIQUE AUQUEL SE RAPPORTE L'INVENTIONTECHNICAL FIELD TO WHICH THE INVENTION REFERS

La présente invention concerne de manière générale l'isolation des ouvertures d'un bâtiment et en particulier un dispositif d'isolation thermique déroulant à interposer entre un vitrage et un volet d'une fenêtre.The present invention generally relates to the insulation of the openings of a building and in particular a thermal insulation device to be interposed interposed between a glazing and a shutter of a window.

ARRIÈRE-PLAN TECHNOLOGIQUETECHNOLOGICAL BACKGROUND

Les fenêtres d'un bâtiment participent en proportion importante aux échanges thermiques entre l'intérieur et l'extérieur de ce bâtiment. Afin de réaliser des économies d'énergie en limitant le chauffage des bâtiments par temps froids ou leur climatisation par temps chauds, l'isolation thermique des fenêtres est renforcée.The windows of a building play an important part in the heat exchange between the interior and the exterior of this building. In order to achieve energy savings by limiting the heating of buildings in cold weather or air conditioning in hot weather, the thermal insulation of windows is enhanced.

L'utilisation de doubles vitrages permet une première réduction des échanges thermiques. Le placement d'un volet devant chaque fenêtre a également une action isolante par l'emprisonnement d'une lame d'air entre le vitrage et le volet.The use of double glazing allows a first reduction of heat exchange. The placement of a shutter in front of each window also has an insulating action by the imprisonment of a blade of air between the glazing and the shutter.

Afin d'améliorer l'isolation thermique des fenêtres, il est connu, notamment du document US5678622 , d'utiliser un dispositif d'isolation thermique de fenêtre déroulant, comportant un matelas isolant comprenant au moins deux parois externes, des moyens de déroulement et d'enroulement de ce matelas isolant entre une configuration enroulée dans laquelle ledit matelas isolant est enroulé autour d'une barre d'enroulement et une configuration déroulée dans laquelle le matelas isolant s'étend dans un plan de déroulement sensiblement parallèle à la barre d'enroulement, et des moyens de déploiement mécaniques du matelas isolant, depuis une configuration reployée dans laquelle le matelas isolant est aplati pour permettre son enroulement, vers une configuration déployée dans laquelle lesdites parois externes sont écartées au moins partiellement l'une de l'autre selon une direction perpendiculaire au plan de déroulement pour emprisonner entre elles une couche d'air.In order to improve the thermal insulation of the windows, it is known, particularly from the document US5678622 to use a drop-window thermal insulation device, comprising an insulating mat comprising at least two external walls, means for unwinding and winding this insulating mat between a wound configuration in which said insulating mat is wound around a mat. a winding bar and an unwrapped configuration in which the insulation blanket extends in a flow plane substantially parallel to the winding bar, and mechanical deployment means of the insulation blanket, from a folded configuration in which the mattress insulation is flattened to allow its winding, to a deployed configuration in which said outer walls are spaced at least partially from one another in a direction perpendicular to the unwinding plane to trap between them a layer of air.

Dans ce document, les parois externes sont réalisées dans un matériau transparent et sont maintenues à distance l'une de l'autre par des lamelles jouant également le rôle de persiennes. La couche d'air emprisonnée entre les parois externes du matelas isolant est libre de circuler dans la direction du déroulement, c'est-à-dire dans une direction parallèle au plan de déroulement et perpendiculaire à la barre de déroulement. Ceci induit des mouvements de convection dans la couche d'air favorisant les échanges thermiques.In this document, the outer walls are made of a transparent material and are kept at a distance from one another by slats also acting as louvers. The air layer trapped between the outer walls of the insulation blanket is free to flow in the direction of unwinding, that is to say in a direction parallel to the unwinding plane and perpendicular to the unwinding bar. This induces convection movements in the air layer favoring heat exchange.

Les qualités d'isolation thermique de ce dispositif restent ainsi très limitées.The thermal insulation qualities of this device thus remain very limited.

On connaît également du document US6068039 un dispositif d'isolation thermique de fenêtre déroulant, comportant un matelas isolant comprenant deux parois externes, adapté à être enroulé et déroulé. Ce dispositif comprend entre outre des moyens de déploiement et et des moyens de cloisonnement interne.Document is also known US6068039 a drop-window thermal insulation device, comprising an insulating mat comprising two outer walls, adapted to be wound and unrolled. This device further comprises deployment means and and internal partitioning means.

According to other advantageous additional features:

On a représenté sur la figure 1 une fenêtre 1 ouverte dans le mur 3 d'un bâtiment. Cette fenêtre 1 est fermée par un vitrage 2 protégé par un volet roulant 10 comportant un tablier 5 déroulant. Ce tablier 5 comprend une pluralité de lames 51 rigides, de forme allongée avec une section généralement courbe adaptée pour permettre l'enroulement du tablier sur lui-même, disposées parallèlement les unes aux autres et articulées entre elles le long de leurs bords longitudinaux.We have shown on the figure 1 a window 1 open in the wall 3 of a building. This window 1 is closed by a glazing 2 protected by a shutter 10 comprising a roll-off apron. This apron 5 comprises a plurality of rigid blades 51, of elongate shape with a generally curved section adapted to allow the winding of the deck on itself, arranged parallel to each other and articulated together along their longitudinal edges.

Ces lames 51 peuvent être réalisées en tout matériau, notamment en bois, en matière plastique, par exemple en PVC, ou en métal, par exemple en aluminium.These blades 51 may be made of any material, in particular wood, plastic, for example PVC, or metal, for example aluminum.

Comme représenté sur les figures 1, 3, 4, 7, 9 et 10, ce volet roulant 10 comporte également une barre d'enroulement 7 qui s'étend selon une direction parallèle aux lames 51 du tablier 5, sur laquelle est fixée l'une 53 des deux lames finales 52, 53 du tablier 5 (figures 4 et 10).As shown on figures 1 , 3 , 4 , 7 , 9 and 10 , this shutter 10 also comprises a winding bar 7 which extends in a direction parallel to the blades 51 of the deck 5, on which is fixed one 53 of the two final blades 52, 53 of the deck 5 ( figures 4 and 10 ).

Le tablier 5 du volet roulant 10 est adapté à être enroulé autour de la barre d'enroulement 7 et déroulé dans un plan P1 de déroulement du tablier 5 du volet roulant 10, parallèle à celui du vitrage 2 et parallèle à la barre d'enroulement 7.The apron 5 of the shutter 10 is adapted to be wound around the winding bar 7 and unwound in a plane P1 unwinding the deck 5 of the shutter 10, parallel to that of the glazing 2 and parallel to the winding bar 7.

Le volet roulant 10 comporte également un couple de coulisses 6;600 (figures 1, 3 ,4, 7, 9 et 10) adaptées à guider le déroulement et l'enroulement du tablier 5.The shutter 10 also comprises a pair of slides 6; 600 ( figures 1 , 3 , 4 , 7 , 9 and 10 ) adapted to guide the unwinding and rolling of the apron 5.

L'autre lame finale 52 du tablier 5 est de préférence renforcée pour assurer la stabilité dimensionnelle de la portion d'extrémité du tablier et, avantageusement mais non nécessairement, pour accroître la résistance à l'effraction du volet en position de fermeture.The other end plate 52 of the deck 5 is preferably reinforced to ensure the dimensional stability of the end portion of the deck and, advantageously but not necessarily, to increase the tamper resistance of the shutter in the closed position.

Chacune des coulisses 6;600 du volet roulant 10 s'étend latéralement, en vis-à-vis, sur une paroi interne latérale 31 opposée de la baie de fenêtre 1 (figure 1).Each of the slides 6, 600 of the roller shutter 10 extends laterally, opposite, on an opposite lateral inner wall 31 of the window bay 1 (FIG. figure 1 ).

Ces deux coulisses 6;600 sont droites et s'étendent parallèlement dans le plan de déroulement P1 du tablier 5 du volet roulant 10. Leur direction de coulissement est donc parallèle au plan de déroulement P1.Elles se présentent sous la forme d'un profilé en U, dont le fond est rapporté sur la face interne latérale 31 correspondante de la baie de fenêtre 1 (figures 5, 8 et 11). Chacune de ces coulisses 6;600 accueille ainsi une extrémité de chaque lame 51 du tablier 5 pour guider le déroulement et l'enroulement de ce tablier 5.These two slides 6, 600 are straight and extend parallel in the unwinding plane P1 of the apron 5 of the shutter 10. Their sliding direction is therefore parallel to the unwinding plane P1. They are in the form of a profile. U-shaped, whose bottom is attached to the corresponding lateral inner face 31 of the window bay 1 ( figures 5 , 8 and 11 ). Each of these slides 6; 600 thus accommodates one end of each blade 51 of the apron 5 to guide the unwinding and winding of this apron 5.

La barre d'enroulement 7 et le volet 5 lorsqu'il est enroulé autour de celle-ci, sont logés dans un coffre 4 aménagé dans le mur 3 (figures 1, 3 ,4, 7, 9 et 10).The winding bar 7 and the flap 5 when it is wrapped around it, are housed in a box 4 arranged in the wall 3 ( figures 1 , 3 , 4 , 7 , 9 and 10 ).

Le volet roulant 10 comporte également des moyens de commande (non représentés) de la rotation de la barre d'enroulement 7 autour de son axe longitudinal pour l'enroulement et le déroulement du tablier 5 du volet isolant 10.The shutter 10 also comprises control means (not shown) for the rotation of the winding bar 7 about its longitudinal axis for the winding and unwinding of the deck 5 of the insulating flap 10.

Ces moyens de commande sont de préférence des moyens de commande motorisés qui peuvent être activés à distance par l'utilisateur grâce à des boutons de commande, mais peuvent tout aussi bien être des moyens de commande manuels utilisant une manivelle ou une sangle.These control means are preferably motorized control means that can be activated remotely by the user through control buttons, but can also be manual control means using a crank or strap.

La fenêtre 1 est également pourvue d'un dispositif 100;200;300 d'isolation thermique déroulant.The window 1 is also provided with a device 100; 200; 300 of thermal insulation drop down.

Différents modes de réalisation du dispositif 100;200;300 d'isolation conforme à l'invention sont représentés sur les figures 1 à 11.Various embodiments of the device 100; 200; 300 of insulation according to the invention are represented on the Figures 1 to 11 .

Le dispositif 100;200;300 d'isolation comporte un matelas isolant 110;210;310 (figures 4, 7 et 10) comprenant deux parois externes 111, 112;211, 212;311, 312, des moyens de déroulement et d'enroulement de ce matelas isolant 100;200;300 entre une configuration enroulée et une configuration déroulée, des moyens de déploiement 120;220;320 mécaniques du matelas isolant 110;210;310 depuis une configuration reployée dans laquelle le matelas isolant 110;210;310 est aplati pour permettre son enroulement, vers une configuration déployée dans laquelle lesdites parois externes 111, 112;211, 212;311, 312 sont écartées au moins partiellement l'une de l'autre pour emprisonner entre elles une couche d'air.The device 100; 200; 300 of insulation comprises an insulating blanket 110; 210; 310 ( figures 4 , 7 and 10 ) comprising two outer walls 111, 112, 211, 212, 311, 312, means for unwinding and winding of this insulating blanket 100, 200, 300 between a wound configuration and an unwrapped configuration, deployment means 120; 320 mechanical insulating blanket 110; 210; 310 from a recessed configuration in which the insulating blanket 110; 210; 310 is flattened to allow its winding, to an expanded configuration in which said outer walls 111, 112; 211, 212; , 312 are spaced at least partially from one another to trap between them a layer of air.

Le matelas isolant 110;210;310 s'enroule autour de la barre d'enroulement 7 du tablier 5 du volet roulant 10 selon les modes de réalisation représentés sur les figures 1 à 4 et 9 à 11, ou autour d'une autre barre d'enroulement 270 distincte de la barre d'enroulement 7 du tablier 5 du volet roulant 10 selon le mode de réalisation représenté sur les figures 6 à 8.The insulating blanket 110; 210; 310 wraps around the winding bar 7 of the apron 5 of the shutter 10 according to the embodiments shown in FIGS. Figures 1 to 4 and 9 to 11 , or around another winding bar 270 distinct from the winding bar 7 of the apron 5 of the shutter 10 according to the embodiment shown in FIGS. Figures 6 to 8 .

Dans sa configuration enroulée, ledit matelas isolant 110;210;310 est enroulé autour de cette barre d'enroulement 7;270. Dans sa configuration déroulée, le matelas isolant 110;210;310 s'étend dans un plan de déroulement sensiblement parallèle à la barre d'enroulement 7;270 et parallèle au plan P1 dans lequel se déroule ledit tablier 5, situé entre le vitrage 2 et le tablier 5 du volet roulant 10.In its wound configuration, said insulating blanket 110; 210; 310 is wound around this winding bar 7; 270. In its unwrapped configuration, the insulating blanket 110; 210; 310 extends in a flow plane substantially parallel to the winding bar 7; 270 and parallel to the plane P1 in which the apron 5 runs, located between the glazing 2 and the apron 5 of the shutter 10.

De manière remarquable, ce matelas isolant 110;210;310 comprend de plus des moyens de cloisonnement 113;213;313 interne ménagés entre ses parois externes 111, 112;211, 212;311, 312 pour s'opposer à la circulation de la couche d'air emprisonnée.Remarkably, this insulating blanket 110; 210; 310 further comprises internal partitioning means 113 formed between its external walls 111, 112, 211, 212, 311, 312 to oppose the circulation of the layer of trapped air.

En l'espèce, lesdits moyens de cloisonnement 113;213;313 comportent une pluralité de cloisons internes 113;213;313 formant une pluralité de canaux 143;243;343 qui s'étendent dans une direction parallèle à celle de la barre d'enroulement 7; 270 autour de laquelle s'enroule le matelas isolant 110;210;310 (figures 4, 7 et 10).In the present case, said partitioning means 113; 213; 313 comprise a plurality of internal partitions 113; 213; 313 forming a plurality of channels 143; 243; 343 which extend in a direction parallel to that of the bar; winding 7; 270 around which the insulation blanket 110; 210; 310 is wound ( figures 4 , 7 and 10 ).

Ces canaux 143;243;343 sont étanches selon la direction parallèle au plan de déroulement du matelas isolant 110;210;310 et perpendiculaire à la barre d'enroulement 7;270 de ce matelas isolant 110;210;310 appelée direction d'enroulement. Ils sont ouverts latéralement.These channels 143; 243; 343 are sealed in the direction parallel to the unwinding plane of the insulating blanket 110; 210; 310 and perpendicular to the winding bar 7; 270 of this insulating blanket 110; 210; 310 called the winding direction . They are open laterally.

La section de ces canaux est de préférence faible, de l'ordre d'au plus quelques centimètres carrés, typiquement de l'ordre de 0,2 à 5 centimètres carré, de préférence d'au plus 2 centimètres carré. Dans l'idéal, cette section est inférieure ou égale à 1 centimètre carré. Les mouvements de l'air emprisonné à l'intérieur de ces canaux 143;243;343 dans la direction d'enroulement sont ainsi très limités. L'air emprisonné dans ces canaux est donc statique et présente peu de mouvements de convection.The section of these channels is preferably small, of the order of at most a few square centimeters, typically of the order of 0.2 to 5 square centimeters, preferably at most 2 square centimeters. Ideally, this section is less than or equal to 1 square centimeter. The movements of air trapped inside these channels 143; 243; 343 in the winding direction are thus very limited. The air trapped in these channels is therefore static and has few convection movements.

Ces canaux 143;243;343 sont par exemple réalisés par soudage desdites cloisons internes 113;213;313 entre elles et par soudage de deux de ces cloisons internes 113;213;313 aux parois externes 111,112;211, 212;311, 312.These channels 143, 243, 343 are for example made by welding said internal partitions 113, 213, 313 to each other and by welding two of these internal partitions 113, 213, 313 to the external walls 111, 112, 211, 212, 311, 312.

Ici le matelas isolant 110;210;310 comporte par exemple six cloisons internes 113;213;313 s'étendant chacune dans un plan moyen globalement parallèle aux parois externes 111,112;211, 212;311, 312 et assemblées deux à deux selon des bandes parallèles à la barre d'enroulement 7;270 du matelas isolant 110;210;310.Here, the insulating blanket 110, 210, 310 comprises, for example, six internal partitions 113, 213, 313 each extending in a mean plane generally parallel to the external walls 111, 112, 211, 212, 311, 312 and assembled in pairs in strips. parallel to the winding bar 7; 270 of the insulating blanket 110; 210; 310.

Les cloisons internes 113;213;313 les plus proches des parois externes 111,112;211, 212;311, 312 du matelas isolant 110;210;310 sont également assemblées à l'une de ces parois externes 111,112;211,212;311, 312 selon des bandes parallèles à la barre d'enroulement 7;270.The internal partitions 113, 213, 313 closest to the outer walls 111, 112, 211, 212, 311, 312 of the insulating blanket 110, 210, 310 are also assembled to one of these external walls 111, 112, 211, 212; strips parallel to the winding bar 7; 270.

Comme représenté sur les figures 4, 7 et 10, les canaux 115;215;315 présentent par exemple une section hexagonale. Alternativement, leur section peut présenter d'autres géométries, par exemple la forme d'un carré, d'un rectangle, d'un autre polygone ou d'un cercle.As shown on figures 4 , 7 and 10 , the channels 115; 215; 315 have for example a hexagonal section. Alternatively, their section may have other geometries, for example the shape of a square, a rectangle, another polygon or a circle.

Les parois externes 111,112;211, 212;311, 312 et les cloisons internes 113;213;313 du matelas isolant 110;210;310 sont de préférence réalisées en films en matière plastique très fins dont l'épaisseur est par exemple comprise entre 10 et 200 micromètres, typiquement de l'ordre de 25 à 100 micromètres. Ces films en matière plastique peuvent également être métallisés.The external walls 111, 112, 211, 212, 311, 312 and the internal partitions 113, 213, 313 of the insulating mat 110, 210, 310 are preferably made of very thin plastic films whose thickness is for example between 10 and 200 microns, typically on the order of 25 to 100 micrometers. These plastic films can also be metallized.

L'assemblage de ces films entre eux est par exemple réalisé par soudage ou collage. Cependant, toute autre méthode d'assemblage connue de l'homme du métier peut être utilisée.The assembly of these films together is for example made by welding or gluing. However, any other assembly method known to those skilled in the art can be used.

De manière également remarquable, les moyens de déploiement 120;220;320 du matelas isolant 110;210;310 opèrent à pression ambiante de la couche d'air emprisonnée entre les parois externes 111,112;211, 212;311, 312 et sont distincts et indépendants desdits moyens de cloisonnement 113;213;313 (figures 3,7 et 9).Also remarkably, the deployment means 120; 220; 320 of the insulating blanket 110; 210; 310 operate at ambient pressure of the layer of air trapped between the outer walls 111, 112, 211, 212, 311, 312 and are distinct and independent of said partitioning means 113; 213; 313 ( figures 3 , 7 and 9 ).

Selon le premier mode de réalisation du dispositif 100 selon l'invention représenté sur les figures 1 à 5a et deux variantes représentées sur les figures 5b et 5c, l'une 111 des parois externes du matelas isolant 110 est solidaire d'une partie du tablier 5 du volet isolant 10 ou au moins reliée à une partie du tablier 5 de sorte que le déplacement de ladite partie du tablier 5 entraîne en déplacement ladite paroi externe 111. Elle est par exemple liée mécaniquement de manière fixe ou démontable, notamment par rivetage, clipsage, ou par un autre moyen tel qu'une colle ou un ruban adhésif repositionnable permettant la séparation temporaire des éléments pour entretien (réparation ou nettoyage). Elle peut comme dans l'exemple représenté être collée à l'une de ses extrémités sur la face interne, tournée vers le vitrage 2 de la fenêtre 1, de la lame finale 52 formant la partie basse du tablier 5 de ce volet roulant 10.According to the first embodiment of the device 100 according to the invention shown in the Figures 1 to 5a and two variants represented on the Figures 5b and 5c , one 111 of the outer walls of the insulating blanket 110 is integral with a portion of the deck 5 of the insulating flap 10 or at least connected to a portion of the deck 5 so that the displacement of said part of the deck 5 drives in displacement said external wall 111. It is for example mechanically linked in a fixed or removable manner, in particular by riveting, clipping, or by another means such a repositionable glue or adhesive tape allowing the temporary separation of the elements for maintenance (repair or cleaning). It can, as in the example shown, be glued to one of its ends on the internal face, facing the glazing 2 of the window 1, of the final strip 52 forming the lower part of the deck 5 of this shutter 10.

Les moyens de déroulement et d'enroulement de ce matelas isolant 110 sont communs au volet roulant 10. Ils comportent la barre d'enroulement 7 du volet roulant 10 et les moyens de commande (non représentés) de la rotation de cette barre d'enroulement 7 autour de son axe longitudinal.The unwinding and winding means of this insulating blanket 110 are common to the shutter 10. They comprise the winding bar 7 of the shutter 10 and the control means (not shown) of the rotation of this winding bar 7 around its longitudinal axis.

Le matelas isolant 110 étant solidaire par sa paroi externe 111 du bas du tablier 5 du volet roulant 10 et ce tablier 5 étant fixé sur la barre d'enroulement 7 par la lame finale 53 formant la partie haute du tablier 5, lorsque la barre d'enroulement 7 tourne dans un sens ou dans l'autre, l'ensemble formé par le volet 5 et le matelas isolant 110 est déroulé ou enroulé en même temps que le tablier 5 du volet roulant 10.The insulating blanket 110 is secured by its outer wall 111 of the bottom of the apron 5 of the shutter 10 and the apron 5 is fixed on the winding bar 7 by the final blade 53 forming the upper part of the deck 5, when the bar winding 7 rotates in one direction or the other, the assembly formed by the flap 5 and the insulating blanket 110 is unwound or wound together with the apron 5 of the shutter 10.

Dans le premier mode de réalisation représenté notamment sur les figures 2 et 5a, sur l'autre paroi externe 112 du matelas isolant 110, appelée paroi externe libre 112, est fixée au moins une baguette de support 114 rigide qui s'étend selon une direction parallèle à la barre d'enroulement 7. Une baguette support inférieure est avantageusement lestée pour favoriser par gravité le déroulement du matelas isolant 110. Des baguettes de support optionnelles 114' sont représentées en trait fin, disposées sur des parties intermédiaires de la surface de la paroi externe libre 112, dont la fonction est de rigidifier ou tendre ladite paroi pendant le déroulement et en position déroulée.In the first embodiment shown in particular on the figures 2 and 5a on the other outer wall 112 of the insulating blanket 110, called the free outer wall 112, is fixed at least one rigid support rod 114 which extends in a direction parallel to the winding bar 7. A lower support rod is advantageously weighted to favor by gravity the unfolding of the insulating blanket 110. Optional support rods 114 'are shown in fine lines, arranged on intermediate portions of the surface of the free outer wall 112, whose function is to stiffen or tension said wall during unwinding and in unwrapped position.

Le terme « rigide » quand il vise ici les baguettes de support signifie « plus rigide que la paroi externe » afin de remplir cette fonction de mise en tension.The term "rigid" when it refers here support rods means "stiffer than the outer wall" to fulfill this function of tensioning.

Par le terme « baguette », on entend aussi bien des torons à section circulaire que des lames planes ou autres éléments de renfort équivalents.The term "rod" means both strands with circular section that plane blades or other equivalent reinforcing elements.

Ces baguettes de support 114 sont par exemple collées sur la paroi externe libre 112.These support rods 114 are for example glued to the free outer wall 112.

Comme représenté plus particulièrement sur la figure 2, la longueur des baguettes de support 114 peut être supérieure à la largeur du matelas isolant 110, et les extrémités 115 de ces baguettes de support 114 font saillie du matelas isolant 110 latéralement.As shown more particularly on the figure 2 , the length of the support rods 114 may be greater than the width of the insulating blanket 110, and the ends 115 of these support rods 114 protrude from the insulating blank 110 laterally.

En variante, les baguettes de support peuvent n'être disposées que dans la partie médiane de la largeur de la paroi externe et être ainsi dissociées des moyens de guidage 115 qui peuvent alors se présenter sous diverses formes.Alternatively, the support rods may be arranged only in the middle portion of the width of the outer wall and thus be dissociated from the guide means 115 which can then be in various forms.

Les moyens de déploiement 120 du matelas isolant 110 comportent deux couples de coulisses 6, 121 plus particulièrement représentés sur la figure 5a. Leur direction de coulissement est globalement parallèle au plan de déroulement du tablier 5 du volet déroulant.The deployment means 120 of the insulating blanket 110 comprise two pairs of slides 6, 121 more particularly represented on the figure 5a . Their sliding direction is generally parallel to the unwinding plane of the deck 5 of the pull-down shutter.

Le couple de coulisses 6 est adapté à guider le tablier 5 du volet roulant 10 lors de son déroulement. La paroi externe 111 du matelas isolant 110 étant solidaire du tablier 5 du volet roulant 10, elle est guidée par les coulisses 6 de guidage du tablier 5.The pair of slides 6 is adapted to guide the deck 5 of the shutter 10 during its course. The outer wall 111 of the insulating blanket 110 being integral with the apron 5 of the shutter 10, it is guided by the guide slides 6 of the apron 5.

Chaque coulisse 121 de l'autre couple de coulisses 121 se présente sous la forme d'un profilé en U semblable à celui de chaque coulisse 6 de guidage du tablier 5 du volet roulant 10.Each slide 121 of the other pair of slides 121 is in the form of a U-shaped profile similar to that of each slide 6 for guiding the deck 5 of the shutter 10.

Le fond de cette coulisse 121 est rapporté sur ladite face interne 31 de la fenêtre 1 (voir figure 5a) entre la coulisse 6 de guidage du tablier 5 du volet roulant 10 et le vitrage 2. Cette coulisse 121 est ainsi adaptée à accueillir chaque extrémité 115 de chaque baguette de support 114 fixée sur la paroi externe libre 112 du matelas isolant 110 lors du déroulement de ce matelas isolant 110.The bottom of this slide 121 is attached to said inner face 31 of the window 1 (see figure 5a ) between the guide slider 6 of the apron 5 of the shutter 10 and the glazing 2. This slide 121 is thus adapted to accommodate each end 115 of each support rod 114 attached to the free outer wall 112 of the insulating blanket 110 during the course of unfolding of this insulating mattress 110.

Chacune des deux coulisses 121 de guidage de la paroi externe libre 112 du matelas isolant 110 comporte à son extrémité 124 la plus proche de la barre d'enroulement 7 une rampe 125 adaptée à forcer la paroi externe libre 112 du matelas isolant 110 à s'écarter de la paroi externe 111 du matelas isolant 110 qui est solidaire du tablier 5 du volet roulant 10, au fil du déroulement du matelas isolant 110 suivant son plan de déroulement.Each of the two guides 121 for guiding the free outer wall 112 of the insulating blanket 110 has at its end 124 closest to the winding bar 7 a ramp 125 adapted to force the free outer wall 112 of the insulating blanket 110 to away from the outer wall 111 of the insulating blanket 110 which is integral with the deck 5 of the shutter 10, as the course of the insulating blanket 110 according to its flow plan.

L'écart entre chaque coulisse 121 de guidage de la paroi externe libre 112 du matelas isolant 110 et la coulisse 6 de guidage du tablier 5 du volet roulant 10 correspondante est très petit au niveau de l'extrémité 124 de chaque coulisse 121 la plus proche de la barre d'enroulement 7. Cet écart augmente progressivement le long de la partie de chaque coulisse 121 de guidage de la paroi externe libre 112 du matelas isolant 110 formant ladite rampe 125. La portion de chaque coulisse 121 qui s'étend entre ladite rampe 125 et l'extrémité de cette coulisse 121 la plus éloignée de la barre d'enroulement 7 est parallèle à la coulisse 6 de guidage du tablier 5 voisine. L'écartement entre les deux coulisses 6, 121 dans cette portion détermine l'épaisseur déployée du matelas isolant. Dans un cas particulier de réalisation, cette distance peut être de l'ordre de 6 centimètres.The distance between each slide 121 for guiding the free outer wall 112 of the insulating blanket 110 and the guiding slide 6 for the apron 5 of the corresponding shutter 10 is very small at the end 124 of each nearest slide 121 of the winding bar 7. This gap increases progressively along the portion of each slide 121 for guiding the free outer wall 112 of the insulating blanket 110 forming said ramp 125. The portion of each slide 121 which extends between said ramp 125 and the end of this slide 121 furthest from the winding bar 7 is parallel to the guide slide 6 of the apron 5 neighbor. The spacing between the two slides 6, 121 in this portion determines the deployed thickness of the insulation blanket. In a particular embodiment, this distance may be of the order of 6 centimeters.

Chaque extrémité 115 des baguettes de support 114 fixées sur la paroi externe libre 112 du matelas isolant 110 est adaptée à prendre appui en coulissant sur une face interne de l'une des parois latérales du profilé en U formant la coulisse 121 correspondante. La coopération des baguettes de support 114 et de cette face interne de chaque coulisse 121 guide la paroi externe libre 112 du matelas isolant 110 pour l'écarter de l'autre paroi externe 111 dans la direction perpendiculaire au plan de déroulement.Each end 115 of the support rods 114 fixed to the free outer wall 112 of the insulating blanket 110 is adapted to bear against an inner face of one of the side walls of the U-shaped section forming the corresponding slider 121. The cooperation of the support rods 114 and this inner face of each slide 121 guides the free outer wall 112 of the insulating blanket 110 to move away from the other outer wall 111 in the direction perpendicular to the unwinding plane.

Lorsque l'utilisateur met en oeuvre le dispositif 100 d'isolation, celui-ci actionne les moyens de commande du matelas isolant 110 pour son déroulement.When the user implements the isolation device 100, the latter actuates the control means of the insulating blanket 110 for its unwinding.

Ces moyens de commande sont couplés aux moyens de commande du déroulement du tablier 5 du volet isolant 10 : le tablier 5 et le matelas isolant 110 se déroulent simultanément.These control means are coupled to the control means of the unwinding of the apron 5 of the insulating flap 10: the apron 5 and the insulating blanket 110 take place simultaneously.

Les moyens de déploiement 120 du matelas isolant 110 agissent automatiquement sur celui-ci au fil de son déroulement : la paroi externe libre 112 est guidée par la rampe 125 de la coulisse 121 au fil du déroulement, et s'éloigne ainsi de la paroi externe 111 solidaire du tablier 5 du volet roulant 10 qui est guidée par la coulisse 6 droite.The deployment means 120 of the insulating blanket 110 act automatically on it as it unfolds: the free outer wall 112 is guided by the ramp 125 of the slide 121 as it unwinds, and thus away from the outer wall 111 secured to the apron 5 of the shutter 10 which is guided by the slide 6 right.

Les canaux 143 étant ouverts latéralement, ils se remplissent d'air au fur et à mesure que les deux parois externes 111, 112 s'écartent, à la façon d'un accordéon.The channels 143 are open laterally, they fill with air as the two outer walls 111, 112 deviate, in the manner of an accordion.

Selon les deux variantes du premier mode de réalisation du dispositif conforme à l'invention représenté sur les figures 5b et 5c, les moyens de guidage sont constitués de têtes de guidage 129;139 fixées sur la paroi externe libre 112 du matelas isolant 110, le cas échéant portées par une bande rapportée en bordure de ladite paroi externe libre 112.According to the two variants of the first embodiment of the device according to the invention shown in the Figures 5b and 5c , the guide means consist of guide heads 129; 139 fixed to the free outer wall 112 of the insulating blanket 110, where appropriate carried by a band attached to the edge of said free outer wall 112.

Ces têtes peuvent présenter tout profil adapté pour être reçu contre une surface de guidage complémentaire.These heads may have any profile adapted to be received against a complementary guide surface.

De façon avantageuse, ces têtes 129;139 présentent un relief saillant dans une direction perpendiculaire au plan de la paroi externe, et la liaison tête/surface de guidage de la coulisse correspondante comporte au moins une butée contre laquelle vient porter le relief en question afin de limiter les déplacements potentiels de la paroi externe dans une direction parallèle au plan de cette dernière.Advantageously, these heads 129, 139 have a relief projecting in a direction perpendicular to the plane of the outer wall, and the link head / guide surface of the corresponding slide comprises at least one abutment against which the relief in question comes to bear. to limit the potential displacements of the outer wall in a direction parallel to the plane of the latter.

Par exemple, comme illustré sur la figure 5b, les têtes 129 peuvent présenter une forme de section essentiellement en T, alors que chaque coulisse 132 associée présente un profil essentiellement en C.For example, as shown on the figure 5b the heads 129 may have a substantially T-shaped section, while each associated slide 132 has a substantially C-shaped profile.

Chaque coulisse 132 comporte ici aux extrémités de ses parois latérales des retours en vis-à-vis jouant le rôle desdites butées. Les têtes 129 sont représentées ici fixées en bordure de la paroi externe libre 112 du matelas isolant 110, ladite bordure étant directement prise entre deux pattes par serrage ou agrafage ou rivetage ou collage ou autre mode de fixation.Each slide 132 comprises here at the ends of its side walls return vis-à-vis playing the role of said stops. The heads 129 are shown here fixed at the edge of the free outer wall 112 of the insulating blanket 110, said edge being directly gripped between two tabs by clamping or stapling or riveting or gluing or other method of attachment.

Ces têtes 129 sont ainsi guidées à la fois longitudinalement dans la direction de coulissement de la coulisse 132, mais aussi transversalement : elles sont retenues dans la coulisse 132 selon une direction parallèle au plan de déroulement et perpendiculaire à la direction de coulissement de la coulisse 132.These heads 129 are thus guided both longitudinally in the sliding direction of the slide 132, but also transversely: they are retained in the slide 132 in a direction parallel to the unwinding plane and perpendicular to the sliding direction of the slide 132.

Dans un autre exemple illustré sur la figure 5c, le guidage par liaison glissière est encore amélioré : les têtes 139 ont la forme d'une bille 139, et la coulisse 142 associée est en deux parties.In another example illustrated on the figure 5c , the slideway guiding is further improved: the heads 139 have the shape of a ball 139, and the associated slide 142 is in two parts.

Une première section 140 de coulisse interne présente un profil globalement en W, dont la partie centrale comprend une chambre de guidage à l'intérieur de laquelle la bille 139 est reçue en butée. Cette chambre de guidage est dotée d'une fente mince pourvue de surfaces de glissement entre lesquelles coulisse le bord de la paroi externe libre 112 du matelas isolant 110.A first section 140 of inner slide has a generally W profile, the central portion comprises a guide chamber within which the ball 139 is received in abutment. This guide chamber is provided with a thin slot provided with sliding surfaces between which slides the edge of the free outer wall 112 of the insulating blanket 110.

Ces billes 139 sont ainsi guidées à la fois longitudinalement dans la direction de coulissement de la coulisse 142, mais aussi transversalement : elles sont retenues dans la coulisse 142 selon une direction parallèle au plan de déroulement et perpendiculaire à la direction de coulissement de la coulisse 142.These balls 139 are thus guided both longitudinally in the sliding direction of the slide 142, but also transversely: they are retained in the slide 142 in a direction parallel to the unwinding plane and perpendicular to the sliding direction of the slide 142 .

Une deuxième section 141 de coulisse externe présente un profil globalement en C. La première section 140 interne au profil en W est incluse dans la deuxième section 141 externe au profil en C, avec le fond du W en regard du fond du C et les extrémités des ailes du W dirigées vers la face interne de retours des paroi latérales du C.A second section 141 of external slide has a generally C profile. The first internal section 140 of the W profile is included in the second section 141 external to the C profile, with the bottom of W facing the bottom of the C and the ends wings of the W directed towards the internal face of returns of the lateral walls of C.

Ces ailes peuvent être constituées d'une matière différente de celle du reste du profilé en W, notamment en matière synthétique souple ou moussée à fonction d'étanchéité et/ou d'amortissement.These wings may be made of a material different from that of the rest of the W-section, in particular flexible or foamed synthetic material with sealing function and / or damping.

Cette configuration permet de fournir une liaison étanche au vent, tout en limitant les risques de blocage de la paroi externe libre 112 du matelas isolant 110 contre les surfaces de guidage serrées.This configuration provides a windtight connection, while limiting the risk of blocking the free outer wall 112 of the insulating blanket 110 against tight guide surfaces.

Hormis la forme de leur profil, la coulisse 132 ;142 de chacune de ces variantes est semblable à la coulisse 121 correspondante décrite dans le premier mode de réalisation et représentée sur les figures 3 et 5a. Le reste du dispositif décrit dans le premier mode de réalisation n'est pas modifié.Apart from the shape of their profile, the slide 132; 142 of each of these variants is similar to the corresponding slide 121 described in the first embodiment and shown in the drawings. figures 3 and 5a . The rest of the device described in the first embodiment is not modified.

Les têtes 129; 139 peuvent être disposées directement sur la bordure de la paroi externe libre 112 ou bien être portées par un ruban (en matière synthétique ou naturelle, en couche pleine ou matériau textile) qui est rapporté sur la bordure de la paroi externe libre 112 par tout moyen, par exemple par collage, thermosoudure ou couture.The heads 129; 139 can be placed directly on the edge of the free outer wall 112 or be carried by a ribbon (of synthetic or natural material, in a solid layer or textile material) which is attached to the edge of the free outer wall 112 by any means for example by gluing, heat sealing or sewing.

Dans chacune de ces variantes, les têtes 129; 139 de guidage peuvent être de dimensions réduites, localisées sur le bord latéral de la paroi externe libre 112 du matelas isolant 110 sur un faible encombrement et ne gênent pas l'enroulement du matelas isolant 110.In each of these variants, the heads 129; 139 of guide can be of reduced dimensions, located on the lateral edge of the free outer wall 112 of the insulating blanket 110 on a small footprint and do not interfere the winding of the insulating blanket 110.

On peut également envisager que lesdites têtes de guidage forment l'extrémité des baguettes décrites dans le premier mode de réalisation.It can also be envisaged that said guide heads form the ends of the rods described in the first embodiment.

Selon une autre variante du premier mode de réalisation du dispositif conforme à l'invention (non représentée), ce dispositif ne comporte pas de baguettes de support fixées sur sa paroi externe libre. En revanche, il comporte une membrane de support fixée contre cette paroi externe libre et sensiblement plus rigide que cette paroi externe.According to another variant of the first embodiment of the device according to the invention (not shown), this device does not have support rods fixed on its free outer wall. However, it comprises a support membrane fixed against this free outer wall and substantially more rigid than the outer wall.

Il peut s'agir d'un film de matière plastique ou de textile tissé ou non tissé, voire d'une combinaison des deux sous la forme d'une toile enduite.It may be a plastic film or a woven or non-woven fabric, or even a combination of both in the form of a coated fabric.

La membrane peut être tramée dans au moins une direction désirée pour renforcer la résistance de la membrane suivant cette direction.The membrane may be woven in at least one desired direction to enhance the resistance of the membrane in that direction.

Un film plastique d'une épaisseur d'environ 0,1 à 2 millimètres peut être envisagé, de préférence d'au moins 0,5 millimètre, par exemple 0,7 millimètre, pour conférer une tenue mécanique satisfaisante à l'ensemble.A plastic film with a thickness of about 0.1 to 2 millimeters may be envisaged, preferably at least 0.5 millimeters, for example 0.7 millimeters, to impart satisfactory mechanical strength to the assembly.

Cette membrane de support permet avantageusement de fixer les dimensions du matelas isolant.This support membrane advantageously allows to fix the dimensions of the insulation blanket.

Les bords latéraux de cette membrane de support font saillie du matelas isolant et sont adaptés à coopérer avec l'une des coulisses des moyens de déploiement du dispositif. La face interne de chaque bord latéral de la membrane de support prend appui sur la face interne de l'aile longitudinale de la coulisse correspondante pour le guidage de cette paroi externe libre le long de la rampe formée par ladite coulisse, de manière à écarter l'une de l'autre les parois externes du matelas isolant au fil du déroulement du matelas isolant.The lateral edges of this support membrane project from the insulating mat and are adapted to cooperate with one of the wings of the deployment means of the device. The internal face of each lateral edge of the support membrane is supported on the inner face of the longitudinal flange of the corresponding slide for guiding this free outer wall along the ramp formed by said slide, so as to remove the one of the other the outer walls of the insulation blanket over the course of the insulation blanket.

Eventuellement, des têtes de guidage telles que décrites en référence à la figure 5b ou 5c peuvent être combinées avec cette membrane.Optionally, guide heads as described with reference to the Figure 5b or 5c can be combined with this membrane.

Alternativement, la paroi externe solidaire du tablier du volet roulant peut également être fixée sur une membrane de support, ladite membrane de support étant alors fixée sur au moins une partie du tablier du volet roulant, de préférence sur la partie basse de celui-ci formant embase commune au matelas isolant et au volet roulant.Alternatively, the integral outer wall of the roll shutter apron can also be fixed on a support membrane, said support membrane then being fixed on at least a portion of the rolling shutter apron, preferably on the lower part thereof. base common to the insulation blanket and shutter.

La mise en oeuvre du dispositif n'est pas modifiée.The implementation of the device is not modified.

Selon un deuxième mode de réalisation du dispositif 200 conforme à l'invention, représenté sur les figures 6 à 8, les parois externes 211, 212 du matelas isolant 210 sont toutes les deux libres et indépendantes du tablier 5 du volet roulant 10. Ce dispositif 200 comporte de plus des moyens d'enroulement et de déroulement du matelas isolant 210 distincts de ceux du volet roulant 10.According to a second embodiment of the device 200 according to the invention, represented on the Figures 6 to 8 , the outer walls 211, 212 of the insulating blanket 210 are both free and independent of the deck 5 of the shutter 10. This device 200 further comprises means for winding and unwinding the insulation blanket 210 separate from those of the shutter 10.

Ces moyens d'enroulement et de déroulement du matelas isolant 210 comportent la barre d'enroulement 270 dédiée logée dans le coffre 4 qui loge la barre d'enroulement 7 du volet roulant 10 (figure 7).These winding and unwinding means of the insulating blanket 210 comprise the dedicated winding bar 270 housed in the trunk 4 which houses the winding bar 7 of the shutter 10 ( figure 7 ).

Une membrane de support 231, 232 est fixée sur chaque paroi externe 211, 212 du matelas isolant 210 (figure 6). Ces membranes de support 231, 232 sont sensiblement plus rigides que lesdites parois externes 211, 212. Elles sont par exemple collées sur lesdites parois externes 111, 112.A support membrane 231, 232 is fixed on each outer wall 211, 212 of the insulating blanket 210 ( figure 6 ). These support membranes 231, 232 are substantially more rigid than said outer walls 211, 212. They are for example bonded to said outer walls 111, 112.

Les membranes de support 231, 232 permettent avantageusement de fixer les dimensions du matelas isolant 210.The support membranes 231, 232 advantageously make it possible to fix the dimensions of the insulating mat 210.

La largeur des membranes de support 231, 232 est supérieure à celle des parois externes 211, 212 du matelas isolant 210 (figure 6). Le bord latéral 233, 234 des membranes de support 231, 232 fait saillie du matelas isolant 210 et est adapté à coopérer avec deux couples de coulisses 221, 222 respectifs pour le guidage de son déroulement et de son enroulement et pour le déploiement de ce matelas isolant 210.The width of the support membranes 231, 232 is greater than that of the outer walls 211, 212 of the insulating mat 210 ( figure 6 ). The lateral edge 233, 234 of the support membranes 231, 232 protrudes from the insulating mat 210 and is adapted to cooperate with two pairs of slides 221, 222 respectively for guiding its unwinding and winding and for the deployment of this mattress insulation 210.

Les moyens de déploiement 220 du matelas isolant 110 comportent lesdits couples de coulisses 221, 222 plus particulièrement représentés sur la figure 8. Ces couples de coulisses 221, 222 présentent par exemple la forme d'un profilé en U ou en C similaire à celle des couples de coulisses 6, 121 du premier mode de réalisation. Elles comportent chacune un fond rapporté sur l'une desdites parois internes latérales 31 opposées de la baie de fenêtre 1 et des parois latérales s'élevant sensiblement perpendiculairement à ce fond.The deployment means 220 of the insulating blanket 110 comprise said pairs of slides 221, 222 more particularly shown in FIG. figure 8 . These pairs of slides 221, 222 have for example the shape of a U-shaped or C-shaped similar to that of the pairs of slides 6, 121 of the first embodiment. They each comprise a bottom attached to one of said side walls 31 opposite side of the window bay 1 and side walls rising substantially perpendicular to the bottom.

La face interne du bord latéral 233, 234 de chaque membrane de support 231, 232 tournée vers la paroi externe 211, 212 correspondante du matelas isolant 210 est adaptée à prendre appui contre l'une des faces internes des parois latérales, ou le cas échéant des ailes de retour, de la coulisse 221, 222 correspondante pour être guidée le long de la coulisse 221, 222 correspondante.The inner face of the lateral edge 233, 234 of each support membrane 231, 232 facing towards the corresponding external wall 211, 212 of the insulating mat 210 is adapted to bear against one of the internal faces of the side walls, or where appropriate return wings, of the slide 221, 222 corresponding to be guided along the slide 221, 222 corresponding.

Ici, chaque coulisse 222 d'un premier des deux couples de coulisses 221, 222 est droite et s'étend parallèlement à la coulisse 6 voisine adaptée à guider le tablier 5 du volet roulant 10 lors de son déroulement.Here, each slide 222 of a first of two pairs of slides 221, 222 is straight and extends parallel to the adjacent slide 6 adapted to guide the deck 5 of the shutter 10 during its unwinding.

Chaque coulisse 221 de l'autre couple de coulisses comporte à son extrémité la plus proche de la barre d'enroulement 270 une rampe 225 adaptée à forcer les membranes de support 231, 232 du matelas isolant 210 à s'écarter l'une de l'autre dans la direction perpendiculaire au plan de déroulement.Each slide 221 of the other pair of slides has at its end closest to the winding bar 270 a ramp 225 adapted to force the support membranes 231, 232 of the insulating blanket 210 to move away from the other in the direction perpendicular to the unwind plane.

Pour cela, comme représenté sur la figure 7, l'écart entre les deux coulisses 221, 222 rapportées est très petit au niveau de leur extrémité la plus proche de la barre d'enroulement 270 et augmente progressivement le long de la partie de la coulisse 221 formant ladite rampe 225. La portion de chaque coulisse 221 qui s'étend entre ladite rampe 225 et l'extrémité de cette coulisse 221 la plus éloignée de la barre d'enroulement 270 est parallèle à la coulisse 222 voisine et à la coulisse 6 de guidage du tablier 5 correspondante.For this, as shown on the figure 7 , the difference between the two slides 221, 222 reported is very small at their end closest to the winding bar 270 and increases gradually along the portion of the slide 221 forming said ramp 225. The portion of each slide 221 which extends between said ramp 225 and the end of this slide 221 the most remote from the winding bar 270 is parallel to the adjacent slide 222 and the guide slide 6 of the corresponding apron 5.

En pratique, lorsque l'utilisateur met en oeuvre le dispositif 200 d'isolation, celui-ci actionne les moyens de commande du matelas isolant 210 pour son déroulement et son déploiement.In practice, when the user implements the isolation device 200, the latter actuates the control means of the insulating blanket 210 for its unwinding and deployment.

Les moyens de commande du déroulement du matelas isolant 210 commandent la rotation de la barre d'enroulement 270 du dispositif d'isolation 200 autour de son axe longitudinal. Ces moyens de commande sont manuels ou motorisés et peuvent être couplés aux moyens de commande du déroulement du volet roulant 10 ou distincts et indépendants de ceux-ci.The control means of the progress of the insulating blanket 210 control the rotation of the winding bar 270 of the insulating device 200 around its longitudinal axis. These control means are manual or motorized and can be coupled to the rolling shutter control means 10 or separate and independent thereof.

Les moyens de commande du déroulement du matelas isolant 210 sont par exemple indépendants des moyens de commande du déroulement du tablier 5 du volet isolant 10. Le matelas isolant 210 peut alors être déroulé quelle que soit la configuration enroulée ou déroulée du tablier 5 du volet roulant 10.The means for controlling the progress of the insulating blanket 210 are, for example, independent of the means for controlling the unwinding of the apron 5 of the insulating flap 10. The insulating blanket 210 can then be unrolled whatever the wound or unwound configuration of the apron 5 of the shutter 10.

Les moyens de déploiement 220 du matelas isolant 210 agissent automatiquement sur celui-ci au fil de son déroulement : la paroi externe 212 est guidée par la rampe 225 de la coulisse 221 au fil du déroulement, et s'éloigne ainsi de la paroi externe 211 qui est guidée par la coulisse 222 droite.The deployment means 220 of the insulating blanket 210 act automatically on it as it unfolds: the outer wall 212 is guided by the ramp 225 of the slide 221 as it unfolds, and thus away from the outer wall 211 which is guided by the right slide 222.

Les canaux 243 étant ouverts latéralement, ils se remplissent d'air au fur et à mesure que les deux parois externes 111, 112 s'écartent.The channels 243 being open laterally, they fill with air as the two outer walls 111, 112 deviate.

En variante, les membranes de support peuvent être remplacées par des baguettes ou lames de support similaires à celles décrites dans le premier mode de réalisation, fixées sur les parois externes du matelas isolant et dont les extrémités latérales coopèrent avec les coulisses de guidage du matelas isolant de la manière décrite précédemment.Alternatively, the support membranes may be replaced by rods or support blades similar to those described in the first embodiment, fixed on the outer walls of the insulation blanket and whose lateral ends cooperate with the guide rails of the insulation blanket as previously described.

On peut également envisager qu'une des parois externes soit fixée sur une membrane de support et que lesdites baguettes ou lames de support soient fixées sur l'autre paroi externe.It is also conceivable that one of the outer walls is fixed on a support membrane and that said rods or support blades are fixed on the other outer wall.

Selon un troisième mode de réalisation du dispositif 300 selon l'invention représenté sur les figures 9 à 11, comme dans le premier mode de réalisation du dispositif 100 selon l'invention, l'une 311 des parois externes du matelas isolant 310 est solidaire d'au moins la partie basse du tablier 5 du volet isolant 10. Elle est par exemple collée sur la face interne, tournée vers le vitrage 2 de la fenêtre 1, de la lame inférieure du tablier 5 de ce volet roulant 10.According to a third embodiment of the device 300 according to the invention shown in the Figures 9 to 11 , as in the first embodiment of the device 100 according to the invention, one 311 of the outer walls of the insulating blanket 310 is secured to at least the lower part of the deck 5 of the insulating flap 10. It is for example glued on the inner face, facing the glazing 2 of the window 1, the lower blade of the deck 5 of the shutter 10.

Comme dans le premier mode de réalisation, les moyens de déroulement et d'enroulement de ce matelas isolant 310 sont communs au volet roulant 10. Ils comportent la barre d'enroulement 7 du volet roulant 10 et les moyens de commande (non représentés) de la rotation de cette barre d'enroulement 7 autour de son axe longitudinal. Les moyens de déroulement et d'enroulement du matelas isolant 310 comportent également les coulisses 600 qui guident les bords latéraux du tablier 5 du volet roulant 10 (figure 10).As in the first embodiment, the unwinding and winding means of this insulating blanket 310 are common to the shutter 10. They comprise the winding bar 7 of the shutter 10 and the control means (not shown) of the rotation of this bar winding 7 about its longitudinal axis. The unwinding and winding means of the insulating blanket 310 also comprise the slides 600 which guide the lateral edges of the apron 5 of the shutter 10 ( figure 10 ).

Le matelas isolant 310 est rattaché au tablier 5 du volet roulant 10 par sa face externe 311 en sa partie basse et, soit à la barre d'enroulement, soit au haut du tablier (éventuellement aux deux à la fois). Le tablier 5 étant fixé sur la barre d'enroulement 7 par l'une de ses lames finales 53, lorsque la barre d'enroulement 7 tourne dans un sens ou dans l'autre, l'ensemble formé par le tablier 5 et le matelas isolant 310 est déroulé ou enroulé. Le matelas isolant 310 est commandé, pour son enroulement et son déroulement, par les moyens de commande de l'enroulement et du déroulement du tablier 5 du volet roulant 10.The insulating blanket 310 is attached to the deck 5 of the shutter 10 by its outer face 311 in its lower part and either to the winding bar or to the top of the deck (possibly both at once). The apron 5 being fixed on the winding bar 7 by one of its end blades 53, when the winding bar 7 rotates in one direction or the other, the assembly formed by the apron 5 and the mattress insulation 310 is unwound or wound. The insulating blanket 310 is controlled, for its winding and unwinding, by the control means of the winding and unwinding of the apron 5 of the shutter 10.

Comme représenté sur les figures 9 et 10, les moyens de déploiement 320 du matelas isolant 310 comportent des moyens mécaniques d'entretoisement 321 disposés entre les deux parois externes 311, 312 du matelas isolant 310 et mobiles entre une position rabattue (figure 9) dans laquelle ils autorisent l'aplatissement et l'enroulement du matelas isolant 310 et une position relevée (figure 10) dans laquelle ils forcent les parois externes 311, 312 du matelas isolant 310 à s'écarter l'une de l'autre.As shown on figures 9 and 10 , the deployment means 320 of the insulating blanket 310 comprise mechanical bracing means 321 disposed between the two outer walls 311, 312 of the insulating blanket 310 and movable between a folded position ( figure 9 ) in which they allow the flattening and winding of the insulation blanket 310 to be lifted and a raised position ( figure 10 ) in which they force the outer walls 311, 312 of the insulating blanket 310 to move away from each other.

Ces moyens d'entretoisement 321 comportent une pluralité de doigts d'entretoisement 321 qui sont par exemple attelés au bord latéral du tablier 5 du volet roulant 10. Avantageusement, ils sont ainsi rattachés à la paroi externe 311 dudit matelas isolant 310 pour plaquer la paroi externe 311 contre le tablier 5 du volet roulant 10 au moins en position déployée.These bracing means 321 comprise a plurality of bracing fingers 321 which are for example coupled to the lateral edge of the apron 5 of the shutter 10. Advantageously, they are thus attached to the outer wall 311 of said insulation blanket 310 to press the wall external 311 against the apron 5 of the shutter 10 at least in the deployed position.

Dans leur position rabattue, les doigts d'entretoisement 321 s'étendent sensiblement parallèlement au tablier 5 du volet roulant 10. L'espacement entre deux doigts d'entretoisement 321 attelés au tablier 5 du volet roulant 10 est de préférence supérieur ou égal à la longueur de chaque doigt d'entretoisement 321, de sorte que, dans leur position rabattue, lesdits doigts d'entretoisement 321 s'alignent les uns derrière les autres, le long de la tranche du tablier du volet roulant, sans se toucher. Le matelas isolant 310 est alors aplati contre la paroi interne du tablier 5 du volet roulant 10 et peut être enroulé autour de la barre d'enroulement 7 avec celui-ci.In their folded position, the bracing fingers 321 extend substantially parallel to the deck 5 of the shutter 10. The spacing between two bracing fingers 321 coupled to the deck 5 of the shutter 10 is preferably greater than or equal to the length of each spacing finger 321, so that, in their folded position, said spacer fingers 321 align one behind the other, along the edge of the apron of the shutter, without touching. The insulation blanket 310 is then flattened against the inner wall of the apron 5 of the shutter 10 and can be wound around the winding bar 7 with it.

Lorsqu'ils passent dans leur position relevée, ces doigts d'entretoisement 321 agissent sur l'autre paroi externe 312 libre du matelas isolant 310, de manière localisée sur ses bords latéraux (figure 10).When they move into their raised position, these spacer fingers 321 act on the other free outer wall 312 of the insulating blanket 310, in a localized manner on its lateral edges ( figure 10 ).

Ici, le matelas isolant 310 comporte une membrane de support 332 fixée contre sa paroi externe 312 libre et sensiblement plus rigide que cette paroi externe 312. Dans leur position relevée, les doigts d'entretoisement 321 repoussent les bords latéraux de ladite membrane de support 332 qui s'écarte alors de la paroi externe 311 du matelas isolant 310 reliée au tablier 5 du volet roulant 10.Here, the insulation blanket 310 comprises a support membrane 332 fixed against its free outer wall 312 and substantially stiffer than this outer wall 312. In their raised position, the spacer fingers 321 push back the lateral edges of said support membrane 332 which then deviates from the outer wall 311 of the insulating mat 310 connected to the deck 5 of the shutter 10.

La longueur de chaque doigt d'entretoisement 321 est environ égale à l'épaisseur maximale souhaitée du matelas isolant 310, soit par exemple environ 6 centimètres dans cet exemple particulier de réalisation.The length of each spacer finger 321 is approximately equal to the desired maximum thickness of the insulation blanket 310, for example about 6 centimeters in this particular embodiment.

Comme représenté sur la figure 11, dans ce mode de réalisation, les coulisses 600 communes aux moyens de déroulement et d'enroulement du matelas isolant 310 et du volet roulant 10 présentent une largeur adaptée à accueillir l'ensemble formé par le tablier 5 du volet roulant 10 et le matelas isolant 300 dans sa configuration déployée.As shown on the figure 11 , in this embodiment, the slides 600 common to the unwinding and winding means of the insulation blanket 310 and the shutter 10 have a width adapted to accommodate the assembly formed by the apron 5 of the shutter 10 and the insulation blanket 300 in its deployed configuration.

Les moyens d'entretoisement sont par exemple commandés pour leur relèvement et leur rabattement par des deuxièmes moyens de commande indépendants des moyens de commande de l'enroulement et du déroulement du tablier 5 du volet roulant 10 .The bracing means are for example controlled for their raising and lowering by second independent control means of the control means of the winding and unwinding of the deck 5 of the shutter 10.

Ces deuxièmes moyens de commande comprennent des tirants souples 350 reliant entre eux lesdits doigts d'entretoisement pour permettre leur actionnement. Ces tirants souples 350 se présentent par exemple sous la forme d'un câble sur lequel est fixé l'extrémité libre de chaque doigt d'entretoisement 321. Alternativement lesdits tirants peuvent être rigides, et comporter une pluralité de tiges articulées entre elles.These second control means comprise flexible tie rods 350 interconnecting said bracing fingers to enable their actuation. These flexible tie rods 350 are for example in the form of a cable on which is fixed the free end of each spacer finger 321. Alternatively said tie rods may be rigid, and have a plurality of rods hinged together.

Ces tirants 350 sont par exemple actionnés par un moyen de commande mécanique automatisé ou manuellement par l'utilisateur.These tie rods 350 are for example actuated by an automated mechanical control means or manually by the user.

En pratique, lorsque l'utilisateur met en oeuvre le dispositif 300 d'isolation, celui-ci actionne les moyens de commande du volet roulant 10 pour son déroulement. Le matelas isolant 310 se déroule en même temps que le tablier 5 du volet roulant 10.In practice, when the user implements the isolation device 300, the latter actuates the control means of the shutter 10 for its unwinding. The insulating mat 310 runs at the same time as the apron 5 of the shutter 10.

Les moyens de déploiement 120 du matelas isolant 110 étant commandés par des moyens de commande indépendants, l'automatisation comporte une temporisation qui actionne les tirants après déroulement complet du matelas isolant 310, ou bien l'utilisateur attend par exemple le déroulement complet du matelas isolant 310, puis actionne les tirants 350 manuellement pour les tendre et relever les doigts d'entretoisement 321. Ceux -ci repoussent la paroi externe libre 312 du matelas isolant 310 dans une direction perpendiculaire au plan de déroulement du matelas isolant 310 et l'écartent ainsi de la paroi externe 311 du matelas isolant 310 solidaire du tablier 5 du volet roulant 10.The deployment means 120 of the insulating blanket 110 being controlled by independent control means, the automation comprises a delay which actuates the tie rods after complete unwinding of the insulating blanket 310, or the user waits for example the complete unwinding of the insulating blanket 310, then actuates the tie rods 350 manually to tension them and raise the spacing fingers 321. These push back the free outer wall 312 of the insulating blanket 310 in a direction perpendicular to the unwinding plane of the insulating blanket 310 and thus separate it the outer wall 311 of the insulating mat 310 secured to the apron 5 of the shutter 10.

Les canaux 343 étant ouverts latéralement, ils se remplissent d'air au fur et à mesure que les deux parois externes 311, 312 du matelas isolant 310 s'écartent.The channels 343 being open laterally, they fill with air as the two outer walls 311, 312 of the insulation blanket 310 deviate.

Alternativement, les tirants peuvent être couplés audits moyens de commande du volet roulant de manière à ce qu'en fin de déroulement du matelas isolant les doigts d'entretoisement se trouvent automatiquement dans leur position relevée. Les tirants sont par exemple rattachés à la barre d'enroulement 7 en une position décalée radialement par rapport au point d'attache de la première lame 53 du tablier 5, de telle sorte que le point d'attache d'un tirant et le point d'attache de la lame forment un segment sensiblement horizontal lorsque le tablier 5 est totalement déroulé.Alternatively, the tie rods can be coupled to said control means of the shutter so that at the end of the course of the insulation blanket bracing fingers are automatically in their raised position. The tie rods are for example attached to the winding bar 7 in a position radially offset from the point of attachment of the first blade 53 of the deck 5, so that the point of attachment of a tie rod and the point attachment of the blade form a substantially horizontal segment when the apron 5 is fully unwound.

En variante, le matelas isolant peut comporter des baguettes de support fixées sur l'une de ses parois externes comme cela est décrit dans le premier mode de réalisation. Les doigts d'entretoisement des moyens de déploiement du matelas isolant coopèrent alors avec les extrémités de ces baguettes de support en les repoussant vers la barre d'enroulement dans leur position relevée.Alternatively, the insulation blanket may comprise support rods attached to one of its outer walls as described in the first embodiment. The bracing fingers of the deployment means of the insulating blanket then cooperate with the ends of these support rods by pushing them towards the winding bar in their raised position.

On peut également envisager que les doigts d'entretoisement et lesdites baguettes de support ne forment qu'une seule pièce.It is also conceivable that the bracing fingers and said support rods form a single piece.

Quel que soit le mode de réalisation de l'invention, le matelas isolant présente une épaisseur comprise entre 2 et 20 centimètres dans sa configuration déployée.Whatever the embodiment of the invention, the insulation blanket has a thickness of between 2 and 20 centimeters in its deployed configuration.

Il est de plus prévu de préférence des joints d'étanchéité 61, 128;61, 228;610 dans chaque coulisse 6, 121; 6, 221, 222;600 qui s'étendent à partir des faces internes des parois latérales de chaque coulisse 6, 121; 6, 221, 222;600 vers l'intérieur de ladite coulisse. Ces moyens d'étanchéité assurent l'étanchéité à l'air entre chaque coulisse et la pièce mécanique qu'elle accueille, à savoir, le tablier 5 du volet roulant 10 et/ou les parois externes du matelas isolant, munies ou non de membrane de support et/ou de baguettes de support.In addition, seals 61, 128, 61, 228, 610 are preferably provided in each channel 6, 121; 6, 221, 222, 600 which extend from the inner faces of the side walls of each slide 6, 121; 6, 221, 222, 600 inwardly of said slide. These sealing means ensure the airtightness between each slide and the mechanical part that it receives, namely, the apron 5 of the shutter 10 and / or the outer walls of the insulation blanket, with or without membrane support and / or support rods.

Ces moyens d'étanchéité comportent par exemple des joints d'étanchéité en matière plastique souple en forme de lèvre flexible, ou bien de forme tubulaire, la matière plastique pouvant être choisie pour fournir un faible coefficient de frottement et/ou être pourvue d'un traitement ou revêtement superficiel favorisant le glissement, tel qu'un traitement à base de substance fluorée ou perfluorée ou un revêtement fibreux dans le cas d'un joint floqué ; ils peuvent aussi comporter des patins de feutre ou des brosses dont les poils s'étendent entre les parois latérales de chaque coulisse .These sealing means comprise, for example, flexible plastic seals in the form of a flexible lip or a tubular shape, the plastic material being able to be chosen to provide a low coefficient of friction and / or to be provided with a surface treatment or coating promoting slippage, such as a fluorine or perfluorinated substance treatment or a fibrous coating in the case of a flocked joint; they may also comprise felt pads or brushes whose bristles extend between the side walls of each slide.

La présente invention n'est nullement limitée aux modes de réalisation décrits et représentés mais l'homme du métier saura y apporter toute variante conforme à son esprit.The present invention is not limited to the embodiments described and shown, but the skilled person will be able to make any variant consistent with his mind.

En particulier, on peut envisager dans le premier mode de réalisation que soient fixées sur la paroi externe libre du matelas isolant une membrane de support et des baguettes de support.In particular, it can be envisaged in the first embodiment that a support membrane and support rods are fixed to the free outer wall of the insulation blanket.

On peut envisager dans le deuxième mode de réalisation que soient fixées sur les deux parois externes libre du matelas isolant une membrane de support et des baguettes de support.It can be envisaged in the second embodiment that are fixed on the two free outer walls of the insulation blanket a support membrane and support rods.

On peut envisager dans les premier et deuxième modes de réalisation que les moyens de déploiement du matelas isolant comportent des coulisses de géométries différentes. Par exemple, on peut prévoir qu'au moins l'une des deux coulisses ne comporte qu'une seule aile longitudinale, sur laquelle prennent appui les bords latéraux de la membrane de support ou les extrémités des baguettes de support.It can be envisaged in the first and second embodiments that the deployment means of the insulation blanket comprise slides of different geometries. For example, it can be provided that at least one of the two wings has only one longitudinal wing, on which bear the lateral edges of the support membrane or the ends of the support rods.

Dans le deuxième mode de réalisation, les moyens de déploiement peuvent comporter une coulisse unique centrale comportant deux faces opposées sur lesquelles prennent appui les parois externes du matelas isolant.In the second embodiment, the deployment means may comprise a central single slider having two opposite faces on which support the outer walls of the insulation blanket.

Dans ce deuxième mode de réalisation, on peut également envisager que les deux coulisses servant au guidage d'un même bord latéral du matelas isolant comportent chacune une rampe, ces deux rampes étant disposées en vis-à-vis et s'écartant l'une de l'autre.In this second embodiment, it can also be envisaged that the two slides serving to guide one and the same lateral edge of the insulating mattress each comprise a ramp, these two ramps being arranged facing each other and diverging one from the other. the other.

Dans tous les cas, on peut aussi envisager que l'élément de guidage soit une partie femelle et l'élément de coulisse associée soit une partie mâle, c'est-à-dire que l'élément de guidage coulisse sur et non dans l'élément de coulisse.In all cases, it can also be envisaged that the guide element is a female part and the associated slide element is a male part, that is to say that the guide element slides on and not in the sliding element.

Par ailleurs, bien que l'invention dispose que les moyens de déploiement opèrent à pression ambiante, elle prévoit néanmoins la possibilité d'adjoindre un dispositif pneumatique pour assurer ou compléter l'étanchéité aux bords du matelas isolant.Furthermore, although the invention provides that the deployment means operate at ambient pressure, it nevertheless provides the possibility of adding a pneumatic device to ensure or complete the seal at the edges of the insulation blanket.

On peut enfin envisager d'installer un dispositif d'isolation thermique tel que celui décrit dans le second mode de réalisation entre un vitrage et tout type de volet, par exemple un volet à battant.Finally, it is possible to envisage installing a thermal insulation device such as that described in the second embodiment between a glazing unit and any type of shutter, for example a flap.

Le dispositif peut être utilisé dans tout type d'ouverture, qu'il s'agisse de fenêtre, porte-fenêtre, fenêtre de toit ou encore d'une porte de garage par exemple.The device can be used in any type of opening, whether it is window, French window, roof window or a garage door for example.

Comme il a été indiqué précédemment, le dispositif ne comporte pas nécessairement de volet, mais peut être employé comme dispositif d'occultation isolant à la manière d'un store déroulant.As previously indicated, the device does not necessarily have a flap, but can be used as an insulating occulting device in the manner of a drop-down blind.

Il peut dans ce cas être installé du côté intérieur d'une fenêtre entre le vitrage et l'espace intérieur de la pièce. Ceci est plus particulièrement indiqué pour les fenêtres de toit ou les fenêtres installées en tunnel.It can in this case be installed on the inside of a window between the glazing and the interior space of the room. This is particularly indicated for roof windows or windows installed in tunnel.
