Description

La présente invention se rapporte à une lame orientable d'occultation pour une installation de protection solaire, ainsi qu'à une installation de protection solaire intégrant plusieurs telles lames.The present invention relates to an orientable shading blade for a sun protection system, and to a sun protection system incorporating several such blades.

L'invention se situe dans le domaine des installations de protection solaire à lames orientables formant une toiture de protection s'ouvrant et se fermant, notamment du type véranda ou pergola à lames orientables.The invention lies in the field of sun protection systems with adjustable blades forming a protective roof opening and closing, including porch type or pergola with adjustable blades.

De telles installations comportent typiquement une structure composée de poteaux qui supportent en partie haute des poutres de support. Sur ces poutres de support sont articulées des lames orientables à leurs extrémités respectives. De manière classique, un système d'entraînement, motorisé ou manuel, coopère avec les lames pour les faire pivoter de manière concomitante ou simultanée entre une position fermée dans laquelle les lames sont sensiblement jointives et horizontales pour fermer la toiture et une position ouverte dans laquelle les lames sont sensiblement verticales pour ouvrir le toit.Such installations typically comprise a structure composed of posts which support support beams in the upper part. On these support beams are articulated steerable blades at their respective ends. Conventionally, a drive system, motorized or manual, cooperates with the blades to rotate concomitantly or simultaneously between a closed position in which the blades are substantially contiguous and horizontal to close the roof and an open position in which the blades are substantially vertical to open the roof.

De manière classique, et comme connu notamment des documents FR 2 982 286 et FR 2 987 061 , une lame est délimitée par deux bords longitudinaux opposés s'étendant selon une direction longitudinale, deux bords d'extrémité opposés reliant les deux bords longitudinaux et s'étendant selon une direction transversale, et une face interne et une face externe opposées, où les bords d'extrémité supportent chacun une articulation définissant un axe de pivotement de la lame parallèle à la direction longitudinale.In a conventional manner, and as known in particular documents FR 2 982 286 and FR 2 987 061 a blade is delimited by two opposite longitudinal edges extending in a longitudinal direction, two opposite end edges connecting the two longitudinal edges and extending in a transverse direction, and an opposite inner face and an opposite face, where the end edges each support a hinge defining a pivot axis of the blade parallel to the longitudinal direction.

Les articulations des lames, souvent matérialisées par des pivots ou axes de pivot, sont généralement décalées vers l'intérieur par rapport aux deux bords longitudinaux, et en particulier sont positionnées sensiblement au milieu des bords d'extrémité. Ainsi, selon la direction transversale, la lame présente successivement un bord longitudinal, puis l'axe de pivotement et enfin l'autre bord longitudinal. Autrement dit, l'axe de pivotement est intercalé entre les deux bords longitudinaux.The joints of the blades, often materialized by pivots or pivot pins, are generally offset inward with respect to the two longitudinal edges, and in particular are positioned substantially in the middle of the end edges. Thus, in the transverse direction, the blade successively has a longitudinal edge, then the pivot axis and finally the other longitudinal edge. In other words, the pivot axis is interposed between the two longitudinal edges.

En position fermée, chaque lame est sensiblement parallèle à un plan horizontal, appelé plan de toiture, passant par les axes de pivotement des lames. Lorsque la lame pivote autour de son axe de pivotement, l'un des bords longitudinaux bascule vers le haut et passe au-dessus du plan de toiture, tandis que l'autre bord longitudinal bascule vers le bas et passe en-dessous du plan de toiture.In the closed position, each blade is substantially parallel to a horizontal plane, called the roof plane, passing through the pivot axes of the blades. As the blade pivots about its pivot axis, one of the longitudinal edges swings up and passes over the roof plane, while the other longitudinal edge swings down and passes below the plane of the roof. roof.

A cause de cette conformation, avec des bords longitudinaux de lames qui passent en-dessous du plan de toiture en position ouverte, il n'est pas possible de prévoir une étanchéité et une isolation thermique des lames lorsqu'elles sont en position fermée. En effet, dans leurs positions fermées, les faces inférieures des lames ne peuvent pas être plaquées sur un élément d'étanchéité et d'isolation, car un tel élément empêcherait alors tout pivotement des lames.Because of this conformation, with longitudinal edges of blades passing below the roof plane in the open position, it is not it is not possible to provide sealing and thermal insulation of the blades when they are in the closed position. Indeed, in their closed positions, the lower faces of the blades can not be pressed on a sealing element and insulation, because such an element would then prevent any pivoting blades.

Par conséquent, les lames sont suspendues dans le vide, sauf au niveau de leurs articulations prévues sur leurs bords d'extrémité, nuisant ainsi à l'étanchéité et surtout à l'isolation thermique de l'installation.Therefore, the blades are suspended in the vacuum, except at their joints provided on their end edges, thus adversely affecting the sealing and especially the thermal insulation of the installation.

De surcroît, les lames sont traditionnellement réalisées dans un matériau thermiquement conducteur, souvent en aluminium ou en acier inoxydable et, bien que l'installation dispose généralement de systèmes d'étanchéités (types joints polymères ou joints brosses) qui offrent une certaine étanchéité à l'air et à l'eau, l'installation subit de fortes transmissions thermiques entre l'intérieur et l'extérieur dues au matériau des lames et également à la condensation de l'eau.In addition, the blades are traditionally made of a thermally conductive material, often made of aluminum or stainless steel, and although the installation generally has sealing systems (polymer joint types or brush seals) which provide a certain degree of watertightness. Air and water, the installation undergoes strong thermal transmissions between the inside and outside due to the material of the blades and also the condensation of water.

La présente invention a pour but de résoudre cet inconvénient en proposant une lame qui permette d'améliorer l'isolation thermique, et accessoirement l'étanchéité à l'air et à l'eau, d'une installation de protection solaire à lames orientables.The present invention aims to solve this disadvantage by providing a blade that improves the thermal insulation, and incidentally airtightness and water, a sun protection system with adjustable blades.

A cet effet, elle propose une lame orientable d'occultation pour une installation de protection solaire, ladite lame étant délimitée par des premier et second bords longitudinaux opposés s'étendant selon une direction longitudinale, des premier et second bords d'extrémité opposés reliant les deux bords longitudinaux et s'étendant selon une direction transversale, et une face interne et une face externe opposées, où les premier et second bords d'extrémité supportent respectivement une première et une seconde articulations définissant un axe de pivotement parallèle à la direction longitudinale, ladite lame étant remarquable en ce que chaque bord d'extrémité présente une partie saillante s'étendant vers l'extérieur au-delà de l'un desdits bords longitudinaux selon la direction transversale, ladite partie saillante supportant l'articulation concernée de sorte que l'axe de pivotement est décalé extérieurement selon la direction transversale vis-à-vis dudit bord longitudinal.For this purpose, it proposes an orientable concealable blade for a sun protection installation, said blade being delimited by first and second opposite longitudinal edges extending in a longitudinal direction, first and second opposite end edges connecting the two longitudinal edges and extending in a transverse direction, and an opposite inner face and an opposite outer face, wherein the first and second end edges respectively support first and second hinges defining a pivot axis parallel to the longitudinal direction, said blade being remarkable in that each end edge has a projecting portion extending outwardly beyond one of said longitudinal edges in the transverse direction, said projecting portion supporting the joint concerned so that pivot axis is shifted outwardly in the transverse direction vis-à-vis said edge longitudinal.

De cette manière, selon la direction transversale, la lame présente successivement un bord longitudinal, puis l'autre bord longitudinal et enfin l'axe de pivotement. Ainsi, en position fermée, la lame est sensiblement parallèle à un plan, appelé plan de toiture, passant par son axe de pivotement. Lorsque la lame pivote autour de son axe de pivotement, les deux bords longitudinaux basculent vers le haut et passent au-dessus du plan de toiture, autrement dit au-dessus de l'axe de pivotement. Grâce à cette conformation, il est donc désormais possible, dans sa position fermée, de plaquer la face inférieure de la lame sur un élément d'étanchéité et d'isolation (décrit ultérieurement sous le libellé poutre d'appui), car un tel élément ne gênera en rien le pivotement de la lame. Au final, une telle lame permet d'améliorer l'isolation thermique, et aussi l'étanchéité à l'air et à l'eau, dans une installation de protection solaire équipée de plusieurs telles lames.In this way, in the transverse direction, the blade successively has a longitudinal edge, then the other longitudinal edge and finally the pivot axis. Thus, in the closed position, the blade is substantially parallel to a plane, called the roof plane, passing through its pivot axis. When the blade pivots about its pivot axis, the two longitudinal edges swing upwards and pass above the roof plane, ie above the pivot axis. With this conformation, it is now possible, in its closed position, to press the lower face of the blade on a sealing element and insulation (described later under the wording support beam), because such an element will not interfere with the pivoting of the blade. Ultimately, such a blade can improve the thermal insulation, and also the airtightness and water, in a solar protection installation equipped with several such blades.

Selon une caractéristique, chaque partie saillante s'étend vers l'extérieur en-dessous de la face interne selon une direction normale orthogonale à ladite face interne, de sorte que l'axe de pivotement est décalé extérieurement selon ladite direction normale vers le bas vis-à-vis de ladite face interne.According to one feature, each protruding portion extends outwardly below the inner face in a normal direction orthogonal to said inner face, so that the pivot axis is offset outwardly in said normal direction downwardly. with respect to said inner face.

En décalant vers le bas l'axe de pivotement, sous le plan de la face interne, la possibilité décrite ci-dessus de pouvoir plaquer la face inférieure de la lame sur un élément d'étanchéité et d'isolation est encore accrue et facilitée.By shifting down the pivot axis, under the plane of the inner face, the possibility described above to be able to press the lower face of the blade on a sealing element and insulation is further increased and facilitated.

Selon une autre caractéristique, chaque articulation comprend un pivot, pour permettre un pivotement de la lame selon l'axe de pivotement.According to another characteristic, each articulation comprises a pivot, to allow pivoting of the blade along the axis of pivoting.

Dans une réalisation particulière, chaque articulation comprend un organe de roulement, notamment du type galet, monté pivotant sur le pivot, pour permettre un pivotement de la lame selon l'axe de pivotement associé à un coulissement de la lame concomitamment audit pivotement.In a particular embodiment, each articulation comprises a rolling member, in particular of the roller type, pivotally mounted on the pivot, to allow pivoting of the blade along the axis of pivoting associated with sliding of the blade concomitant with said pivoting.

En effet, la lame conforme à l'invention peut soit être mobile uniquement en rotation, soit être mobile à la fois en rotation et en pivotement pour permettre de rétracter les lames et dégager quasi-entièrement la toiture.Indeed, the blade according to the invention can either be mobile only in rotation, or be movable both in rotation and pivoting to allow retracting the blades and almost completely clear the roof.

Avantageusement, la lame comprend :

  • un panneau central délimité par des premier et second côtés longitudinaux opposés s'étendant selon la direction longitudinale, des premier et second côtés d'extrémité opposés s'étendant selon la direction transversale, et une face interne et une face externe opposées ; et
  • des premier et second supports longitudinaux fixés sur les premier et second côtés longitudinaux respectifs dudit panneau central.
Advantageously, the blade comprises:
  • a central panel defined by first and second opposite longitudinal sides extending in the longitudinal direction, first and second opposite end sides extending in the transverse direction, and an opposite inner face and an opposite outer face; and
  • first and second longitudinal supports attached to respective first and second longitudinal sides of said central panel.

Cette conformation permet ainsi d'employer un panneau central qui présentera des qualités d'isolation thermique, plutôt que d'employer une lame monobloc réalisée entièrement en matériau thermiquement conducteur ; la rigidité de la lame étant garantie avec les supports longitudinaux qui soutiennent le panneau central.This conformation thus makes it possible to employ a central panel which will have thermal insulation qualities, rather than employing a one-piece blade made entirely of thermally conductive material; the rigidity of the blade being guaranteed with the longitudinal supports that support the central panel.

Dans un mode de réalisation particulier, le panneau central est du type panneau sandwich composite et comprend une âme centrale intercalée entre deux peaux externes.In a particular embodiment, the central panel is of the composite sandwich panel type and comprises a central core interposed between two outer skins.

Un tel panneau sandwich composite offrira des qualités d'isolation thermique qui amélioreront encore l'isolation thermique de l'installation.Such a composite sandwich panel will offer thermal insulation qualities that will further improve the thermal insulation of the installation.

Selon une possibilité de l'invention, chaque support longitudinal est du type profilé à rupture de pont thermique et comprend un profilé inférieur longitudinal, un profilé supérieur longitudinal et au moins une barrette isolante en matière plastique intercalée entre le profilé inférieur et le profilé supérieur.According to a possibility of the invention, each longitudinal support is of the profile type with thermal break and comprises a longitudinal lower section, a longitudinal upper profile and at least one plastic insulating strip interposed between the lower section and the upper profile.

Grâce à de tels profilés à rupture de pont thermique, l'isolation thermique de l'installation, entre l'intérieur et l'extérieur, est encore améliorée.Thanks to such profiles with thermal break, the thermal insulation of the installation, between the inside and outside, is further improved.

Selon une autre possibilité de l'invention, chaque support longitudinal comprend un plateau inférieur collé sur la face interne du panneau central et un plateau supérieur collé sur la face externe du panneau central, de sorte que chaque côté longitudinal du panneau central est enchâssé entre les plateaux inférieur et supérieur du support longitudinal correspondant.According to another possibility of the invention, each longitudinal support comprises a lower plate glued on the internal face of the central panel and an upper plate glued on the outer face of the central panel, so that each longitudinal side of the central panel is embedded between the lower and upper trays of the corresponding longitudinal support.

Ainsi, le panneau central est rigidement fixé aux supports longitudinaux, avec recouvrement par les plateaux inférieur et supérieur, pour une isolation et une étanchéité accrues.Thus, the central panel is rigidly fixed to the longitudinal supports, with overlap by the lower and upper trays, for increased insulation and sealing.

Selon une autre possibilité de l'invention, la lame comprend, sur chaque côté d'extrémité du panneau central, une plaque de fermeture recouvrant ledit côté d'extrémité et fixée sur les extrémités concernées desdits supports longitudinaux, où ladite plaque de fermeture présente la partie saillante supportant l'articulation concernée.According to another possibility of the invention, the blade comprises, on each end side of the central panel, a closure plate covering said end side and fixed on the relevant ends of said longitudinal supports, where said closure plate has the protruding part supporting the joint concerned.

Ainsi, les parties saillantes sont prévues sur des plaques de fermeture rapportées fixement sur les côtés d'extrémité du panneau central, pour une tenue mécanique accrue.Thus, the protrusions are provided on closure plates fixedly attached to the end sides of the central panel, for increased mechanical strength.

Conformément à une autre caractéristique avantageuse de l'invention, sont prévues :

  • sur le premier bord longitudinal, une première aile faisant saillie vers le haut et dépassant au-dessus de la face externe de la lame, ladite aile étant incurvée vers l'intérieur de la lame ; et
  • sur le second bord longitudinal, une seconde aile faisant saillie vers le haut et dépassant au-dessus de la face externe de la lame, ladite aile étant incurvée vers l'extérieur de la lame ;
de sorte que, en situation sur une installation de protection solaire avec plusieurs lames adjacentes en position fermée, la seconde aile d'une lame vient en recouvrement de la première aile d'une lame adjacente.According to another advantageous characteristic of the invention, there are provided:
  • on the first longitudinal edge, a first wing projecting upwardly and protruding above the outer face of the blade, said wing being curved towards the inside of the blade; and
  • on the second longitudinal edge, a second wing projecting upwardly and protruding above the outer face of the blade, said wing being curved towards the outside of the blade;
so that, in a situation on a sun protection system with several adjacent blades in the closed position, the second wing of a blade overlaps the first wing of an adjacent blade.

Ces ailes vont garantir l'étanchéité de la toiture lorsque les lames sont en position fermée, avec un recouvrement entre les ailes contigües des lames adjacentes, avec la seconde aile qui vient chapeauter la première aile.These wings will ensure the tightness of the roof when the blades are in the closed position, with a covering between the adjacent wings of the adjacent blades, with the second wing which is to cap the first wing.

Avantageusement, un joint d'étanchéité est prévu sur le dessous de la seconde aile et/ou sur le dessus de la première aile, pour renforcer l'étanchéité lors du recouvrement entre les ailes de deux lames adjacentes, le joint d'étanchéité se retrouvant écrasé entre les deux ailes concernées.Advantageously, a seal is provided on the underside of the second wing and / or on the top of the first wing, to reinforce the seal when covering between the wings of two adjacent blades, the seal being found crushed between the two wings concerned.

La présente invention se rapporte également à une installation de protection solaire à lames orientables formant une toiture de protection s'ouvrant et se fermant, du type comprenant plusieurs lames conformes à l'invention, ces lames étant articulées sur une structure porteuse entre deux configurations de l'installation :

  • une configuration fermée dans laquelle les lames sont sensiblement jointives et parallèles à un plan dit de toiture pour fermer la toiture ; et
  • une configuration ouverte dans laquelle les lames présentent une inclinaison supérieure à 45° par rapport au plan de toiture pour ouvrir la toiture ;
cette installation comprenant en outre un système d'entraînement comprenant au moins un actionneur associé à au moins un mécanisme de transmission coopérant avec les articulations des lames pour faire pivoter les lames de manière concomitante entre la configuration ouverte et la configuration fermée, et inversement.The present invention also relates to a sun protection system with steerable blades forming a protective opening and closing roof, of the type comprising a plurality of blades according to the invention, these blades being articulated on a support structure between two configurations of the installation:
  • a closed configuration in which the blades are substantially contiguous and parallel to a so-called roof plane to close the roof; and
  • an open configuration in which the blades have an inclination greater than 45 ° with respect to the roof plane to open the roof;
this installation further comprising a drive system comprising at least one actuator associated with at least one transmission mechanism cooperating with the joints of the blades for pivoting the blades concomitantly between the open configuration and the closed configuration, and vice versa.

Comme décrit précédemment, une telle installation présente l'avantage de pouvoir offrir une isolation thermique accrue comparativement à des installations classiques.As previously described, such an installation has the advantage of being able to offer increased thermal insulation compared to conventional installations.

Selon une caractéristique, la structure porteuse comprend :

  • des première et seconde poutres de support s'étendant selon la direction transversale et sur lesquelles sont articulées respectivement les premières et secondes articulations des lames ; et
  • des première et seconde poutres d'appui s'étendant selon la direction transversale et décalées selon la direction longitudinale vers l'intérieur des lames relativement aux première et seconde poutres de support respectives ; où les première et seconde poutres d'appui sont disposées de sorte que les faces inférieures des lames viennent en appui, de préférence sur toute la largeur des lames, sur les première et seconde poutres d'appui lorsque les lames sont en configuration fermée.
According to one characteristic, the carrying structure comprises:
  • first and second support beams extending in the transverse direction and on which are articulated respectively the first and second joints of the blades; and
  • first and second support beams extending in the transverse direction and offset in the longitudinal direction inwardly of the blades relative to the respective first and second support beams; wherein the first and second support beams are arranged so that the lower faces of the blades abut, preferably over the entire width of the blades, on the first and second support beams when the blades are in closed configuration.

Ainsi, grâce aux conformations des lames (et plus particulièrement grâce à la disposition de leurs axes de pivotement respectifs), les faces inférieures des lames peuvent venir en appui, en position fermée, contre des poutres d'appui qui forment les éléments d'étanchéité et d'isolation décrit précédemment. Ainsi, lorsque la toiture est fermée, les lames sont en appui sur ces poutres d'appui, garantissant une isolation thermique et une étanchéité entre l'intérieur et l'extérieur ; la face interne d'une lame étant prévue pour être tournée vers l'intérieur de l'espace à protéger tandis que la face externe est prévue pour être tournée vers l'extérieur.Thus, thanks to the conformations of the blades (and more particularly thanks to the arrangement of their respective pivot axes), the lower faces of the blades can bear, in the closed position, against supporting beams which form the sealing elements. and isolation described above. Thus, when the roof is closed, the blades are supported on these support beams, ensuring thermal insulation and sealing between the inside and the outside; the inner face of a blade being provided to be turned towards the inside of the space to be protected while the outer face is intended to be turned outwards.

Avantageusement, les première et seconde poutres d'appui supportent chacune au moins un joint d'étanchéité supérieur sur lesquelles les faces inférieures des lames viennent se plaquer lorsque les lames sont en configuration fermée, améliorant ainsi l'isolation thermique et l'étanchéité.Advantageously, the first and second support beams each support at least one upper seal on which the lower faces of the blades are pressed when the blades are in closed configuration, thus improving the thermal insulation and sealing.

Selon une autre caractéristique, chaque poutre d'appui est du type profilé à rupture de pont thermique et comprend un profilé intérieur transversal, un profilé extérieur transversal et au moins une barrette isolante en matière plastique intercalée entre le profilé intérieur et le profilé extérieur.According to another characteristic, each support beam is of the profile type with thermal break and comprises a transverse inner profile, a transverse outer profile and at least one insulating strip of plastic interposed between the inner profile and the outer profile.

Ainsi, grâce à de tels profilés à rupture de pont thermique, l'isolation thermique de l'installation, entre l'intérieur et l'extérieur, est encore améliorée.Thus, thanks to such profiles with thermal break, the thermal insulation of the installation, between the inside and the outside, is further improved.

Dans une réalisation particulière avec des lames pourvues d'organes de roulement, la structure porteuse comprend des première et seconde poutres de support s'étendant selon la direction transversale et sur lesquelles sont articulées respectivement les premières et secondes articulations des lames, où chaque poutre de support comprend un rail de guidage réceptionnant les organes de roulement des articulations concernées des lames, et le mécanisme de transmission est conformé pour faire coulisser les organes de roulement à l'intérieur des rails de guidage des poutres de support concomitamment au pivotement des lames autour de leurs axes de pivotement respectifs, de sorte que, dans la configuration fermée, les lames sont déployées le long des poutres de support et, dans la configuration ouverte, les lames sont rétractées et rassemblées les unes contre les autres à une extrémité de la structure porteuse.In a particular embodiment with blades provided with rolling members, the carrying structure comprises first and second support beams extending in the transverse direction and on which are articulated respectively the first and second joints of the blades, where each beam of support comprises a guide rail receiving the rolling members of the joints concerned blades, and the transmission mechanism is shaped to slide the rolling members within the guide rails of the support beams concomitantly with the pivoting of the blades around their axes of respective pivoting, so that, in the closed configuration, the blades are deployed along the support beams and, in the open configuration, the blades are retracted and assembled against each other at one end of the carrier structure.

Ainsi, l'installation est à lames orientables et rétractables, offrant une toiture presque complètement ouverte.Thus, the installation is with adjustable and retractable blades, offering a roof almost completely open.

Selon une possibilité, le mécanisme de transmission du système d'entraînement comprend au moins un mécanisme à pantographe coopérant avec les bords d'extrémité des lames, où le ou chaque mécanisme à pantographe comprend plusieurs bras présentant chacun trois attaches articulées à pivot selon des axes parallèles aux axes de pivotement des lames, dont une première attache prévue à une extrémité supérieure du bras et articulée sur le bord d'extrémité concerné d'une première lame, une seconde attache prévue sensiblement au centre du bras et articulée sur le bord d'extrémité concerné d'une deuxième lame adjacente à la première lame, et une troisième attache prévue à une extrémité inférieure du bras et articulée sur le bord d'extrémité concerné d'une troisième lame adjacente à la deuxième lame.According to one possibility, the transmission mechanism of the drive system comprises at least one pantograph mechanism cooperating with the end edges of the blades, wherein the or each pantograph mechanism comprises a plurality of arms each having three pivotally articulated fasteners along axes parallel to the pivot axes of the blades, including a first fastener provided at an upper end of the arm and articulated on the end edge of a first blade, a second fastener provided substantially in the center of the arm and articulated on the edge of the arm; concerned end of a second blade adjacent to the first blade, and a third fastener provided at a lower end of the arm and hinged to the relevant end edge of a third blade adjacent to the second blade.

Selon une autre possibilité, l'actionneur du système d'entraînement comprend un vérin pourvu d'une tige coulissante pourvue d'une extrémité reliée au mécanisme de transmission qui convertit le déplacement de la tige en un coulissement des organes de roulement dans les rails de guidage correspondants.According to another possibility, the actuator of the drive system comprises a jack provided with a sliding rod provided with an end connected to the transmission mechanism which converts the displacement of the rod into a sliding of the rolling members in the rails of corresponding guidance.

La description détaillée qui suit porte sur une lame 2 orientable d'occultation prévue pour équiper une installation 1 de protection solaire.The detailed description which follows relates to a blade 2 orientable occultation provided to equip a plant 1 of sun protection.

Chaque lame 2 s'étend selon une direction longitudinale X dans le sens de sa longueur, et comporte :

  • un panneau central 3 délimité par des premier et second côtés longitudinaux 31, 32 opposés s'étendant selon la direction longitudinale X, des premier et second côtés d'extrémité opposés s'étendant selon une direction transversale Y dans le sens de la largeur, et une face interne 33 et une face externe 34 opposées ; et
  • des premier et second supports longitudinaux 41, 42 fixés sur les premier et second côtés longitudinaux 31, 32 respectifs du panneau central 3.
Each blade 2 extends in a longitudinal direction X in the direction of its length, and comprises:
  • a central panel 3 delimited by first and second longitudinal sides 31, 32 opposite extending in the longitudinal direction X, first and second opposite end sides extending in a transverse direction Y in the direction of the width, and an inner face 33 and an outer face 34 opposite; and
  • first and second longitudinal supports 41, 42 fixed on the respective first and second longitudinal sides 31, 32 of the central panel 3.

Le panneau central 3 est du type panneau sandwich composite et comprend une âme centrale 30 intercalée entre deux peaux externes, à savoir une peau interne définissant la face interne 33 et une peau externe définissant la face externe 34. Les faces interne et externe 33, 34 du panneau central 3 définissent les faces interne et externe respectives de la lame 2.The central panel 3 is of the composite sandwich panel type and comprises a central core 30 interposed between two outer skins, namely an inner skin defining the inner face 33 and an outer skin defining the outer face 34. The inner and outer faces 33, 34 of the central panel 3 define the respective inner and outer faces of the blade 2.

L'âme 30 du panneau central 3 présente deux faces opposées sur lesquelles les peaux externes sont fixées, notamment par collage.The core 30 of the central panel 3 has two opposite faces on which the outer skins are fixed, in particular by gluing.

Le matériau de l'âme 30 est notamment choisi parmi les matériaux suivants :

  • matériaux polymères organiques, notamment expansés ou extrudés, réalisés de préférence sous forme de mousse poreuse (eg. mousse de polyuréthane, mousse de polyester, mousse de polyéther, ...) ;
  • matériaux inorganiques, notamment expansés ou extrudés, réalisés de préférence sous forme de mousse poreuse tel que des mousses de verre ;
  • mousses de silicone ;
  • matériaux fibreux réalisés à base de cellulose ou de fibres naturelles ; et
  • matériaux fibreux réalisés à base de bois.
The material of the core 30 is in particular chosen from the following materials:
  • organic polymeric materials, especially foamed or extruded, preferably in the form of porous foam (eg polyurethane foam, polyester foam, polyether foam, etc.);
  • inorganic materials, especially foamed or extruded, preferably made in the form of porous foam such as glass foams;
  • silicone foams;
  • fibrous materials made from cellulose or natural fibers; and
  • fibrous materials made from wood.

Les peaux externes sont plus rigides que l'âme 30 et peuvent comprendre une armature fibreuse. En variante, les peaux peuvent être réalisées sans armature fibreuse, par exemple dans des matériaux tels que le bois, le métal, les céramiques, les plastiques thermoplastiques, etc.The outer skins are stiffer than the core 30 and may comprise a fibrous reinforcement. Alternatively, the skins can be made without fibrous reinforcement, for example in materials such as wood, metal, ceramics, thermoplastic plastics, etc.

Le panneau central 3 présente une forme substantiellement parallélépipédique, bordé en longueur par ses côtés longitudinaux 31, 32, en largeur et à ses extrémités par ses côtés d'extrémité, et par ses peaux externes.The central panel 3 has a substantially parallelepipedal shape, bordered in length by its longitudinal sides 31, 32, in width and at its ends by its end sides, and by its outer skins.

Les supports longitudinaux 41, 42 présentent des bords longitudinaux externes 410, 420, opposées au panneau central 3, qui forment respectivement les premier et second bords longitudinaux opposés de la lame 2.The longitudinal supports 41, 42 have external longitudinal edges 410, 420, opposite to the central panel 3, which respectively form the first and second opposite longitudinal edges of the blade 2.

Les supports longitudinaux 41, 42 sont chacun du type profilé à rupture de pont thermique. Chaque support longitudinal 41, 42 comprend un profilé inférieur 411, 421 longitudinal, un profilé supérieur 412, 422 longitudinal et au moins une barrette isolante 413, 423 (par exemple deux barrettes isolantes comme illustré sur les figures 5 et 6) en matière plastique intercalée entre le profilé inférieur 411, 421 et le profilé supérieur 412, 422.The longitudinal supports 41, 42 are each of the profile type thermal break. Each longitudinal support 41, 42 comprises a lower profile 411, 421 longitudinal, an upper profile 412, 422 longitudinal and at least one insulating strip 413, 423 (for example two insulating bars as shown in FIGS. Figures 5 and 6 ) of plastic interposed between the lower profile 411, 421 and the upper profile 412, 422.

Les profilés 411, 421, 412, 422 sont réalisés dans un métal ou un alliage de métal, et notamment en aluminium. Les profilés 411, 421, 412, 422 présentent des gorges qui reçoivent les barrettes isolantes 413, 423 concernées.The profiles 411, 421, 412, 422 are made of a metal or an alloy of metal, and in particular aluminum. The profiles 411, 421, 412, 422 have grooves which receive the insulating strips 413, 423 concerned.

Chaque support longitudinal 41, 42 comprend :

  • un plateau inférieur 414, 424 qui est partie intégrante du profilé inférieur 411, 421 et qui est collé sur la face interne 33 du panneau central 3 ; et
  • un plateau supérieur 415, 425 qui est partie intégrante du profilé supérieur 412, 422 et qui collé sur la face externe 34 du panneau central 3.
Each longitudinal support 41, 42 comprises:
  • a lower plate 414, 424 which is an integral part of the lower section 411, 421 and which is bonded to the inner face 33 of the central panel 3; and
  • an upper plate 415, 425 which is an integral part of the upper profile 412, 422 and which is stuck on the outer face 34 of the central panel 3.

Ainsi, chaque côté longitudinal 31, 32 du panneau central 3 est enchâssé entre les plateaux inférieur 414, 424 et supérieur 415, 425 du support longitudinal 41, 42 correspondant; les barrettes isolantes 413, 423 assurant la rupture de pont thermique entre les plateaux inférieur 414, 424 et les plateaux supérieurs 415, 425.Thus, each longitudinal side 31, 32 of the central panel 3 is set between the lower plates 414, 424 and upper 415, 425 of the corresponding longitudinal support 41, 42; insulating strips 413, 423 providing the thermal break between the lower trays 414, 424 and the upper trays 415, 425.

Par ailleurs, pour des questions d'étanchéité vis-à-vis des eaux pluviales et d'évacuation de ces eaux pluviales, il est prévu d'avoir :

  • sur le premier bord longitudinal 410, une première aile 416 faisant saillie vers le haut et dépassant au-dessus de la face externe 34, cette première aile 416 faisant partie intégrante du profilé supérieur 412 et étant incurvée vers l'intérieur de la lame 2 ; et
  • sur le second bord longitudinal 420, une seconde aile 426 faisant saillie vers le haut et dépassant au-dessus de la face externe 34, ladite seconde aile 426 faisant partie intégrante du profilé supérieur 422 et étant incurvée vers l'extérieur de la lame 2.
In addition, for issues of rainwater sealing and evacuation of rainwater, it is planned to have:
  • on the first longitudinal edge 410, a first flange 416 projecting upwardly and protruding above the outer face 34, this first flange 416 forming an integral part of the upper profile 412 and being curved towards the inside of the blade 2; and
  • on the second longitudinal edge 420, a second flange 426 projecting upwardly and projecting above the outer face 34, said second flange 426 forming an integral part of the upper section 422 and being curved towards the outside of the blade 2.

Chaque aile 416, 426 se présente sous la forme d'un pan de départ incliné par rapport à la face externe 34, selon un angle non droit, prolongé par un pan d'extrémité sensiblement parallèle à la face externe 34. La seconde aile 426 présente en outre, le long du pan d'extrémité, un rebord orienté vers la face externe 34. De plus, un joint d'étanchéité 427 longitudinal est prévu sur le dessous de la seconde aile 426 ; un tel joint d'étanchéité pouvant également être prévu sur le dessus de la première aile 416. Le joint d'étanchéité 427 peut par exemple être du type joint en polymère (de forme tubulaire ou en forme de bande) ou joint brosse.Each wing 416, 426 is in the form of a start pan inclined relative to the outer face 34, at a non-straight angle, extended by an end portion substantially parallel to the outer face 34. The second wing 426 furthermore, along the end panel, there is a flange oriented towards the outer face 34. In addition, a longitudinal seal 427 is provided on the underside of the second flange 426; such a seal may also be provided on the top of the first flange 416. The seal 427 may for example be of the polymer seal type (tubular or band-shaped) or brush seal.

La seconde aile 426 est légèrement plus haute selon la direction normale Z de sorte que, en situation sur une installation en configuration fermée et comme visible sur le zoom de la figure 5, la seconde aile 426 d'une lame 2 vient en recouvrement de la première aile 416 d'une lame 2 adjacente, avec le joint d'étanchéité 427 qui se trouve intercalé et écrasé entre ces deux ailes 416, 426.The second wing 426 is slightly higher in the normal direction Z so that, when in a closed configuration and as visible on the zoom of the figure 5 , the second wing 426 of a blade 2 overlaps the first wing 416 of an adjacent blade 2, with the seal 427 which is interposed and crushed between these two wings 416, 426.

Il est également prévu un joint d'étanchéité 428 longitudinal sur le second bord longitudinal 420, et plus spécifiquement sur le profilé inférieur 421 du second support longitudinal 42 ; un tel joint d'étanchéité 428 pouvant également être prévu sur le premier bord longitudinal 410, et notamment sur le profilé inférieur 411 du premier bord longitudinal 410. Le joint d'étanchéité 428 peut par exemple être du type joint en polymère (de forme tubulaire ou en forme de bande) ou joint brosse.There is also provided a longitudinal seal 428 on the second longitudinal edge 420, and more specifically on the lower profile 421 of the second longitudinal support 42; such a seal 428 may also be provided on the first longitudinal edge 410, and in particular on the lower profile 411 of the first longitudinal edge 410. The seal 428 may for example be of the polymer seal type (of tubular form or strip-shaped) or brush seal.

Ainsi, en situation sur une installation 1 en configuration fermée et comme visible sur le zoom de la figure 5, le premier bord longitudinal 410 d'une lame 2 et le second bord longitudinal 420 d'une lame 2 adjacente sont sensiblement jointifs, avec le joint d'étanchéité 428 qui se trouve intercalé et écrasé entre ce premier bord longitudinal 410 et ce second bord longitudinal 420.Thus, in situation on an installation 1 in closed configuration and as visible on the zoom of the figure 5 , the first longitudinal edge 410 of a blade 2 and the second longitudinal edge 420 of an adjacent blade 2 are substantially contiguous, with the seal 428 which is interposed and crushed between the first longitudinal edge 410 and the second longitudinal edge 420.

Chaque lame 2 comprend en outre, sur chaque côté d'extrémité du panneau central 3, une plaque de fermeture 5 recouvrant le côté d'extrémité du panneau central 3 et fixée (notamment par vissage ou rivetage) sur les extrémités concernées des deux supports longitudinaux 41, 42.Each blade 2 further comprises, on each end side of the central panel 3, a closure plate 5 covering the end side of the central panel 3 and fixed (in particular by screwing or riveting) on the relevant ends of the two longitudinal supports 41, 42.

Ces plaques de fermeture 5 ferment ainsi les côtés d'extrémité du panneau central 3. Les profilés 411, 421, 412, 422 présentent des orifices longitudinaux prévus pour la réception de vis qui plaqueront et fixeront les plaques de fermeture 5 sur les extrémités des profilés 411, 421, 412, 422 ; ces orifices longitudinaux étant notamment ménagés sous la forme d'alvéoles internes de forme générale en « C » ou « O », classiquement appelées alvéovis.These closure plates 5 thus close the end sides of the central panel 3. The profiles 411, 421, 412, 422 have longitudinal openings provided for receiving screws which will press and fix the closure plates 5 on the ends of the profiles 411, 421, 412, 422; these longitudinal orifices being in particular formed in the form of internal cells of general shape in "C" or "O", conventionally called alveovis.

Chaque plaque de fermeture 5 présente une partie centrale 50 couvrant les côtés d'extrémité du panneau central 3 et munie d'orifices de passage des vis, et également une partie saillante 51 supportant une articulation 6 de la lame 2. Ainsi, les plaques de fermeture 5 forment les premier et second bords d'extrémité opposés de la lame 2 et supportent des première et seconde articulations 6 définissant un axe de pivotement A de la lame 2, cet axe de pivotement A étant parallèle à la direction longitudinale X.Each closure plate 5 has a central portion 50 covering the end sides of the central panel 3 and provided with screw holes, and also a projecting portion 51 supporting a hinge 6 of the blade 2. Thus, the plates of closure 5 form the first and second opposite end edges of the blade 2 and support first and second hinges 6 defining a pivot axis A of the blade 2, this pivot axis A being parallel to the longitudinal direction X.

La partie saillante 51 s'étend vers l'extérieur au-delà du premier bord longitudinal 410 selon la direction transversale Y et s'étend également vers l'extérieur en-dessous de la face interne 33 selon une direction dite normale Z orthogonale à la face interne 33.The projecting portion 51 extends outwardly beyond the first longitudinal edge 410 in the transverse direction Y and also extends outwardly below the inner face 33 in a so-called normal direction Z orthogonal to the inner face 33.

L'articulation 6 est située à l'extrémité libre de la partie saillante 51, de sorte que l'axe de pivotement A est, d'une part, décalé extérieurement selon la direction transversale Y vis-à-vis du premier bord longitudinal 410 et, d'autre part, est décalé extérieurement selon la direction normale Z vers le bas vis-à-vis de la face interne 33.The hinge 6 is located at the free end of the projecting portion 51, so that the pivot axis A is, on the one hand, externally offset in the transverse direction Y vis-à-vis the first longitudinal edge 410 and, on the other hand, is shifted outwardly in the normal direction Z downwards with respect to the internal face 33.
