Description

L'invention concerne une lame métallique, notamment pour système de fermeture de bâtiment, de type porte sectionnelle, volet ou similaire, comportant une paroi avant et une paroi arrière délimitant un espace interne à ladite lame, notamment apte à recevoir un matériau isolant.The invention relates to a metal blade, in particular for a building closure system, of the sectional door type, shutter or the like, comprising a front wall and a rear wall delimiting a space internal to said blade, in particular adapted to receive an insulating material.

Dans le domaine des systèmes de fermeture de bâtiment, tel que les volets roulants et plus particulièrement les portes sectionnelles de garage, le tablier que comporte ce volet ou cette porte est habituellement constitué d'une juxtaposition de lames sous forme de profilés en matériau synthétique ou de type métallique.In the field of building closure systems, such as roller shutters and more particularly sectional garage doors, the apron included in this shutter or door usually consists of a juxtaposition of blades in the form of profiles made of synthetic material or of metallic type.

Justement, dans le cas des portes sectionnelles comportant des lames de grande largeur, celles-ci sont conçues le plus fréquemment en métal, par pliage d'une tôle, de manière à définir la paroi avant et la paroi arrière de cette lame, sachant qu'après pliage les bords longitudinaux de la tôle sont rendus solidaires, notamment par sertissage, lequel apparaît, selon le cas, au niveau du chant supérieur ou inférieur de la lame. D'ailleurs, ces chants supérieur et inférieur des lames sont profilés de manière à autoriser l'emboîtement de ces dernières les unes sur les autres et garantir une rigidité et étanchéité de la porte ou du volet. Ces moyens d'emboîtement que conçoivent ces chants supérieur et inférieur desdites lames sont encore configurés pour permettre, dans certains cas, l'articulation des lames entre elles et, dans le cas d'une porte sectionnelle à ouverture verticale, autoriser le refoulement du tablier d'une telle porte le long du plafond d'un garage.Indeed, in the case of sectional doors with wide blades, they are most frequently made of metal, by folding a sheet, so as to define the front wall and the rear wall of this blade, knowing that after folding the longitudinal edges of the sheet are made integral, in particular by crimping, which appears, as the case, at the upper or lower edge of the blade. Moreover, these upper and lower edges of the blades are profiled so as to allow the interlocking of the latter on each other and ensure rigidity and tightness of the door or shutter. These interlocking means designed by these upper and lower edges of said blades are further configured to allow, in some cases, the articulation of the blades together and, in the case of a sectional door with vertical opening, allow the backing of the deck such a door along the ceiling of a garage.

Même s'il est préservé un espacement entre la paroi avant et la paroi arrière de ces lames conçues par pliage d'une tôle, la continuité au niveau du matériau entre la paroi avant et la paroi arrière constitue un pont thermique en assure une parfaite conductivité, selon le cas de la chaleur ou du froid, depuis l'intérieur vers l'extérieur ou vice versa. L'injection d'un matériau isolant, notamment de polyuréthane, à l'intérieur de telles lames n'améliore guère la situation, dans tous les cas, ne répond pas au problème du pont thermique.Although a gap between the front wall and the rear wall of these blades designed by folding of a sheet is preserved, the continuity of the material between the front wall and the rear wall is a thermal bridge ensures perfect conductivity, depending on the case of heat or cold, from the inside to the outside or vice versa. The injection of an insulating material, especially polyurethane, inside such blades does not improve the situation, in any case, does not respond to the problem of thermal bridge.

Toutefois, de telles lames réalisées par pliage et sertissage d'une tôle, qui plus est, injectée de polyuréthane, sont d'une très grande rigidité, en particularité à la flexion et répondent, parfaitement, aux contraintes mécaniques et sollicitations auxquelles peuvent être soumis des systèmes de fermeture de bâtiment de grandes dimensions, tels que des portes sectionnelles de grandes largeurs.However, such blades made by folding and crimping a sheet, which is more, injected with polyurethane, are of great rigidity, particularity in bending and perfectly meet the mechanical stresses and stresses to which may be subject large building closure systems, such as sectional doors of large widths.

I1 est encore connu, plutôt que de sertir les deux bords longitudinaux de la tôle après pliage, d'assurer leur liaison par collage, au moyen d'un mastic adapté. D'ailleurs, il est également connu de concevoir ces lames partant d'une paroi avant et d'une paroi arrière individualisées, pour autant réalisées par profilage d'une tôle, parois que l'on solidarise par collage au moyen d'un mastic isolant, à la fois en bordure longitudinale supérieure et inférieure de ladite lame, de manière à éviter le pont thermique.It is still known, rather than crimping the two longitudinal edges of the sheet after folding, to ensure their connection by gluing, by means of a suitable sealant. Moreover, it is also known to design these blades starting from a front wall and an individualized rear wall, provided by profiling a sheet, walls that are secured by bonding with a putty insulation, both at the upper and lower longitudinal edge of said blade, so as to avoid the thermal bridge.

Evidemment de telles opérations de collage s'avèrent de mise en oeuvre bien plus longue et délicate en comparaison au sertissage. A cela il faut ajouter qu'il est quasiment impossible de maîtriser, avec précision, l'épaisseur de colle, donc de mastic, entre les bords solidarisés des parois, notamment en raison de la longueur de ces dernières, mais aussi de leur conception par profilage.Obviously, such bonding operations turn out to be much longer and more delicate than crimping. To this it must be added that it is almost impossible to control, with precision, the thickness of glue, therefore mastic, between the edges of the walls, particularly because of the length of the latter, but also their design by profiling.

Comme dans le cas d'une tôle repliée sur elle-même, il est usuel d'injecter, entre ces parois avant et arrière de la lame, un matériau isolant, notamment du polyuréthane. Ce matériau, tout comme le mastic de collage d'ailleurs, pose le problème du recyclage de ces lames en fin de vie. En effet, il est impossible de séparer les matériaux synthétiques du métal, donc de valoriser l'un ou l'autre dans ce cas.As in the case of a folded sheet on itself, it is customary to inject, between these front and rear walls of the blade, an insulating material, especially polyurethane. This material, everything like the adhesive putty besides, poses the problem of recycling these blades at the end of their life. Indeed, it is impossible to separate the synthetic materials from the metal, so to value one or the other in this case.

Il convient encore de remarquer que de cette liaison entre la paroi avant et la paroi arrière d'une lame, dépendent les caractéristiques mécaniques de cette dernière, notamment sa tenue à la déformation.It should also be noted that this connection between the front wall and the rear wall of a blade, depend on the mechanical characteristics of the latter, including its resistance to deformation.

Il est également connu par le document GB-A-2 157 752 une lame à double paroi, notamment pour volet roulant, comportant une paroi externe et une paroi interne sous forme d'un profilé en aluminium ou en acier, rendues solidaires, au niveau de leurs chants longitudinaux supérieurs et inférieurs, par l'intermédiaire de profilés d'assemblage, qui, s'ils peuvent être conçus en aluminium, peuvent également être réalisés en matière plastique extrudé.He is also known by the document GB-A-2 157 752 a double-walled blade, in particular for a shutter, comprising an outer wall and an inner wall in the form of an aluminum or steel profile, made integral, at the level of their upper and lower longitudinal edges, by means of profiles assembly, which, if they can be made of aluminum, can also be made of extruded plastic.

Ces profilés, définissant, substantiellement, le chant supérieur et inférieur de la lame, comportent, selon le cas, des moyens d'assemblage mâle ou femelle pour garantir la liaison entre deux lames successives.These profiles, defining, substantially, the upper and lower edge of the blade, comprise, as appropriate, male or female assembly means to ensure the connection between two successive blades.

Pour leur liaison avec les parois avant et arrière de la lame, ces profilés, notamment en matière plastique, comportent, sur chacun de leurs côtés longitudinaux, une aile, dont la bordure d'extrémité est repliée en forme de crochet. Tandis que les parois avant et arrière comportent, elles-mêmes, leur bordure longitudinale supérieure et inférieure repliée, de manière à pouvoir se superposer aux ailes des profilés d'assemblage, tout en venant s'engager dans la bordure en forme de crochet que comporte chacune de ces ailes.For their connection with the front and rear walls of the blade, these profiles, in particular plastic, comprise, on each of their longitudinal sides, a wing, whose end edge is folded hook-shaped. While the front and rear walls themselves have their upper and lower longitudinal edge folded, so as to be superimposed on the wings of the assembly profiles, while engaging in the hook-shaped edge that includes each of these wings.

En somme, il est assuré, ici, un simple accrochage entre les profilés et les parois avant et arrière de la lame, sachant que l'ensemble est solidarisé au moyen de l'injection dans cette lame d'une mousse en matériau synthétique.In short, it is assured, here, a simple hooking between the profiles and the front and rear walls of the blade, knowing that the assembly is secured by means of the injection into this blade of a foam of synthetic material.

La présente invention se veut à même de répondre à l'ensemble des contraintes dans la conception de ces lames pour systèmes de fermeture de bâtiment.The present invention is intended to meet all the constraints in the design of these blades for building closure systems.

En particulier, la présente invention consiste en une lame à coupure de pont thermique parfaitement maîtrisée entre la paroi avant et la paroi arrière, ceci sans usage de colle. Pour autant, une telle lame selon l'invention est capable de performances mécaniques élevées en rapport aux contraintes qu'elle est susceptible de subir.In particular, the present invention consists of a thermal bridge cut blade perfectly controlled between the front wall and the rear wall, without the use of glue. However, such a blade according to the invention is capable of high mechanical performance in relation to the stresses it is likely to undergo.

Par ailleurs, la conception de ces lames à coupure de pont thermique selon l'invention permet l'intégration d'un matériau isolant susceptible de répondre aux conditions de recyclage de ces lames en fin de vie.Furthermore, the design of these blades thermal bridge cut according to the invention allows the integration of an insulating material capable of meeting the recycling conditions of these blades at the end of life.

A cet effet, l'invention concerne une lame métallique, notamment pour système de fermeture de bâtiment, de type porte sectionnelle, volet roulant ou similaire, comportant une paroi avant et une paroi arrière sous forme de profilés métalliques distincts rendus solidaires au niveau de leurs bords longitudinaux au moins suivant une direction transversale à la lame par un profilé de verrouillage en matériau isolant, notamment synthétique conçu apte à constituer une coupure de pont thermique entre lesdits bords longitudinaux de ces profilés. Tout particulièrement, ces derniers comportent, au niveau de leurs bords longitudinaux, des moyens de blocage conçus aptes à coopérer entre eux et/ou au travers de moyens de blocage complémentaires associés au profilé de verrouillage, pour assurer l'immobilisation en translation axiale longitudinale de ces profilés entre eux.For this purpose, the invention relates to a metal blade, in particular for a building closure system, such as a sectional door, roller shutter or the like, comprising a front wall and a rear wall in the form of separate metal sections that are secured to each other. longitudinal edges at least in a direction transverse to the blade by a locking profile of insulating material, especially synthetic designed capable of constituting a thermal break between said longitudinal edges of these profiles. In particular, the latter comprise, at their longitudinal edges, blocking means designed to cooperate with each other and / or through complementary blocking means associated with the locking profile, to ensure the immobilization in longitudinal axial translation of these profiles between them.

Selon une autre particularité de l'invention, au moins un des profilés de verrouillage reliant les profilés métalliques à l'un des bords longitudinaux de ces derniers, conçoit un joint d'étanchéité défini apte à coopérer avec une lame adjacente.According to another feature of the invention, at least one of the locking profiles connecting the metal profiles to one of the longitudinal edges thereof, design a defined seal adapted to cooperate with an adjacent blade.

D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre se rapportant à des modes de réalisation illustrés dans les dessins ci-joints dans lesquels :

  • La figure 1 est une représentation schématisée et une coupe transversale d'une lame conforme à l'invention, selon un premier mode de réalisation.
  • La figure 2 est une vue en perspective et éclatée de la lame tel que visible dans la figure 1.
  • Les figures 3 et 4 sont des représentations similaires aux figures 1 et 2 pour une lame correspondant à un second mode de réalisation.
  • Les figures 5 et 6 sont des représentations similaires aux figures 1 et 2 ou encore 3 et 4 dans le cas d'une lame exécutée selon un troisième mode de réalisation.
Other objects and advantages of the present invention will become apparent from the following description relating to embodiments illustrated in the accompanying drawings in which:
  • The figure 1 is a schematic representation and a cross section of a blade according to the invention, according to a first embodiment.
  • The figure 2 is a perspective and exploded view of the blade as visible in the figure 1 .
  • The Figures 3 and 4 are representations similar to Figures 1 and 2 for a blade corresponding to a second embodiment.
  • The Figures 5 and 6 are representations similar to Figures 1 and 2 or else 3 and 4 in the case of a blade executed according to a third embodiment.

Tel que visible dans les figures des dessins ci-joints, la présente invention concerne le domaine des lames, plus particulièrement en métal, appliqué à des systèmes de fermeture de bâtiment, tels que volets, portes, portes sectionnelles, etc.As shown in the figures of the accompanying drawings, the present invention relates to the field of blades, particularly metal, applied to building closure systems, such as shutters, doors, sectional doors, etc.

Une telle lame 1 comporte une paroi avant 2 et une paroi arrière 3 sous forme de profilés métalliques indépendants, respectivement, 4 et 5.Such a blade 1 comprises a front wall 2 and a rear wall 3 in the form of independent metal profiles, respectively, 4 and 5.

Ces profilés 4, 5 sont rendus solidaires l'un de l'autre au niveau de leurs bordure longitudinales 6, 7. Avantageusement, mais non nécessairement, la jonction de ces profilés métalliques 4, 5, formant les parois avant 2 et arrière 3, intervient au niveau du chant supérieur 8 et inférieur 9 de la lame 1.These profiles 4, 5 are secured to one another at their longitudinal edges 6, 7. Advantageously, but not necessarily, the junction of these metal sections 4, 5, forming the front walls 2 and rear 3, occurs at the upper edge 8 and lower 9 of the blade 1.

Ces profilés 4, 5, ainsi assemblés, délimitent un évidement tubulaire 10 dans la lame 1, évidement susceptible d'accueillir un matériau isolant 11 comme cela apparaîtra plus en détail dans la description qui va suivre.These sections 4, 5, thus assembled, delimit a tubular recess 10 in the blade 1, recessably capable of accommodating an insulating material 11 as will appear in more detail in the following description.

Selon l'invention, les profilés métalliques 4, 5 sont rendus solidaires au niveau de leurs bordures longitudinales 6, 7 au moyen d'un profilé de verrouillage 12, 13 avantageusement en un matériau isolant, notamment synthétique, de manière à former un pont thermique entre les parois avant 2 et arrière 3.According to the invention, the metal sections 4, 5 are made integral at their longitudinal edges 6, 7 by means of a locking profile 12, 13 advantageously made of an insulating material, in particular a synthetic material, so as to form a thermal bridge between the front walls 2 and rear 3.

Un tel profilé de verrouillage 12, 13 vient solidariser lesdits profilés 4, 5 au moins suivant une direction transversale, c'est-à-dire perpendiculaire à la lame 1.Such a locking profile 12, 13 comes to secure said profiles 4, 5 at least in a transverse direction, that is to say perpendicular to the blade 1.

Aussi, ce profilé de verrouillage 12, 13 comporte essentiellement, une lame 14 destinée à former entretoise, donc apte à constituer une coupure de pont thermique entre lesdites bordures longitudinales 6, 7. Cette lame 14 s'étend depuis une embase 15 comportant des moyens de retenue 16 destinés à coopérer avec lesdites bordures longitudinales 6, 7 des profilés métalliques 4, 5 pour maintenir ces derniers assemblés.Also, this locking profile 12, 13 essentially comprises a blade 14 intended to form a spacer, thus capable of constituting a thermal break between said longitudinal edges 6, 7. This blade 14 extends from a base 15 comprising means retainer 16 for cooperating with said longitudinal edges 6, 7 of the metal sections 4, 5 to maintain the latter assemblies.

Comme illustré dans les modes de réalisation correspondants aux figures 2, 3 et 4, ces moyens de retenue 16 peuvent être définis par des languettes de retenue 17, 17a s'étendant, depuis l'embase 15, parallèlement de part et d'autre de la lame 14 de manière à emprisonner, en coopération avec cette dernière, l'une ou l'autre des bordures longitudinales 6 ; 7, ceci par emboîtement dudit profilé de verrouillage 12, 13 sur ces dernières.As illustrated in the embodiments corresponding to Figures 2, 3 and 4 these retaining means 16 may be defined by retaining tongues 17, 17a extending, from the base 15, parallel on either side of the blade 14 so as to trap, in cooperation with the latter, the one or the other of the longitudinal edges 6; 7, this by interlocking said locking profile 12, 13 on the latter.

Dans le mode de réalisation illustré dans les figures 5 et 6, ces moyens de retenue 16 sont définis, au niveau de l'embase 15 de ces profilés de verrouillage 12, 13, par des ouvertures discontinues 21 aptes à accueillir des languettes équidistantes 22 en forme de créneau en bordure longitudinale 6, 7 des profilés métalliques 4,5.In the embodiment illustrated in the Figures 5 and 6 , these retaining means 16 are defined, at the base 15 of these locking profiles 12, 13, by discontinuous openings 21 adapted to receive equidistant tongues 22 in the form of a crenel along the longitudinal edge 6, 7 of the metal profiles 4.5.

Un profilé de verrouillage 12, 13 comporte encore des moyens d'ancrage 18 destinés à coopérer avec des moyens d'ancrage complémentaires 19 équipant lesdites bordures longitudinales 6, 7 des profilés métalliques 4,5 pour empêcher, après emboîtement, le déboîtement de ce profilé de verrouillage 12, 13.A locking profile 12, 13 also comprises anchoring means 18 intended to cooperate with complementary anchoring means 19 fitted to said longitudinal edges 6, 7 of the metal profiles 4,5 to prevent, after interlocking, the disengagement of this profile. locking 12, 13.

Dans le mode de réalisation des figures 1 et 2, les moyens d'ancrage 18 consistent en des extrémités de languettes de retenue 17, 17a configurées en forme de redans en direction de la lame 14, tandis que, du côté des bordures longitudinales 6, 7 des profilés métalliques 4, 5, les moyens d'ancrage complémentaires 19 se présentent sous forme de lamelles 24 découpées par emboutissage au niveau de ces bordures 6, 7 et formant rebord d'accrochage à même de coopérer avec lesdites extrémités formant redan 23 des languettes de retenue 17, 17a.In the embodiment of Figures 1 and 2 , the anchoring means 18 consist of ends of retaining tongues 17, 17a configured in the form of steps in the direction of the blade 14, whereas, on the side of the longitudinal edges 6, 7 of the metal sections 4, 5, the means complementary anchors 19 are in the form of strips 24 cut by stamping at these edges 6, 7 and forming hooking flange able to cooperate with said redan ends 23 retaining tongues 17, 17a.

Dans le mode de réalisation correspondant aux figures 3 et 4, les moyens d'ancrage 18 que comportent un profilé de verrouillage 12, 13 sont définis par une extrémité en forme de harpon 25 de la lame 14, tandis que les moyens d'ancrage complémentaires 19 sont là encore conçus sous forme de lamelles 24 découpées par emboutissage en bordure 6, 7 des profilés métalliques 4, 5. En coopération avec l'extrémité en forme de harpon 25, plus particulièrement les rebords d'accrochage 26, 27 définis par cette dernière, ces lamelles 24 sont conçues aptes à former redan après emboîtement du profilé de verrouillage 12, 13 pour s'opposer au retrait de ce dernier.In the embodiment corresponding to Figures 3 and 4 , the anchoring means 18 that comprise a locking profile 12, 13 are defined by a spear-shaped end 25 of the blade 14, while the complementary anchoring means 19 are again designed in the form of cut strips 24 by edge stamping 6, 7 of the metal sections 4, 5. In cooperation with the spear-shaped end 25, more particularly the hooking flanges 26, 27 defined by the latter, these strips 24 are designed to form redan after interlocking of the locking profile 12, 13 to oppose the withdrawal of the latter.

A noter que pour faciliter l'emboîtement d'un profilé de verrouillage 12, 13 plus particulièrement pour permettre le passage de l'extrémité en forme de harpon 25 au travers de l'étranglement défini par les lamelles 24 entre les bordures 6, 7 des profilés 4, 5, ladite lame 14 est fendue dans le sens longitudinal de manière à lui conférer une élasticité dans le sens de l'épaisseur autorisant ce franchissement.Note that to facilitate the interlocking of a locking profile 12, 13 more particularly to allow the passage of the spear-shaped end 25 through the constriction defined by the slats 24 between the edges 6, 7 of the sections 4, 5, said blade 14 is slotted in the longitudinal direction so as to give it an elasticity in the direction of the thickness allowing this crossing.

Comme il est illustré dans le mode de réalisation correspondant aux figures 5 et 6, le profilé de verrouillage 12, 13, plus particulière la lame 14 de ce dernier, peut ne comporter que sur certains tronçons 27 sur sa longueur, une extrémité 25 en forme de harpon, cette lame 14 n'étant d'ailleurs fendue, dans son épaisseur, qu'au niveau de ces tronçons 27. En outre, dans ce mode de réalisation des figures 5 et 6, les moyens d'ancrage complémentaire 19, en bordure 6, 7 des profilés métalliques 4, 5 ne sont pas conçus sous forme de lamelles formant redan, mais par un rebord d'accrochage 28, 28a situé sensiblement intérieurement à la lame 1 et constituant, en quelque sorte, des rebords d'accrochage complémentaires à ceux 26, 26a que définissent les extrémités en forme de harpon 25 de la lame 14.As illustrated in the embodiment corresponding to the Figures 5 and 6 , the locking profile 12, 13, more particularly the blade 14 of the latter, may have only on certain sections 27 along its length, a spear-shaped end 25, this blade 14 not being slotted, in its thickness, that at these sections 27. In addition, in this embodiment of the Figures 5 and 6 , the complementary anchoring means 19, at the edge 6, 7 of the metal sections 4, 5 are not designed as redan lamellae, but by a hooking flange 28, 28a located substantially internally to the blade 1 and constituting in a way, hooking flanges complementary to those 26, 26a defined by the spear-shaped ends 25 of the blade 14.

Selon une autre particularité de l'invention, les profilés métalliques 4, 5 comportent respectivement des moyens de blocage 29 conçus aptes à assurer l'immobilisation en translation axiale de ces profilés 4, 5 entre eux, sachant que de tels moyens de blocage 29 peuvent encore coopérer avec des moyens de blocage complémentaires 29a d'un profilé de verrouillage 12, 13 dans ce même but d'immobilisation relativement d'un profilé 4 par rapport à un autre 5 dans la direction longitudinale de la lame 1.According to another particularity of the invention, the metal sections 4, 5 respectively comprise locking means 29 designed capable of immobilizing in axial translation these sections 4, 5 between them, knowing that such locking means 29 can still cooperate with complementary locking means 29a of a locking profile 12, 13 for the same purpose of immobilizing relatively one profile 4 with respect to another 5 in the longitudinal direction of the blade 1.

Dans les modes de réalisation correspondant aux figures 1 et 2, d'une part, et 3 et 4, d'autre part, lesdits moyens de blocage 29 s'apparentent à des créneaux que comportent en bordure longitudinale 6, 7 lesdits profilés métalliques 4, 5, créneaux conçus aptes à venir s'emboîter les uns dans les autres lorsque l'on vient réunir lesdits profilés pour former la lame 1.In the embodiments corresponding to Figures 1 and 2 on the one hand, and 3 and 4, on the other hand, said locking means 29 are similar to crenels which comprise, along the longitudinal edge 6, 7 said metal sections 4, 5, slots designed adapted to come into engagement with each other when it comes to bring together said profiles to form the blade 1.

Ainsi, dans le mode de réalisation des figures 1 et 2, la bordure longitudinale 6 d'un profilé 4 est découpée de manière à définir des languettes équidistantes 30, l'espace libre préservé entre deux languettes successives étant défini pour accueillir une languette 30a que comporte en bordure longitudinale 6 le profilé 5 adjacent.Thus, in the embodiment of Figures 1 and 2 , the longitudinal edge 6 of a profile 4 is cut so as to define equidistant tongues 30, the free space preserved between two successive tongues being defined to accommodate a tongue 30a that has along the longitudinal edge 6 the adjacent section 5.

Ces languettes 30, 30a sont réparties en quinconce de part et d'autre du plan médian longitudinal 31 de la lame 1 en respectant entre elles, suivant une direction perpendiculaire à ce plan, une distance pour l'engagement de la lame 14 évitant le pont thermique d'un profilé de verrouillage 12, 13.These tongues 30, 30a are distributed in staggered rows on either side of the longitudinal median plane 31 of the blade 1 while respecting each other, in a direction perpendicular to this plane, a distance for the engagement of the blade 14 avoiding the bridge thermal of a locking profile 12, 13.

Dans le mode de réalisation des figures 3 et 4, les créneaux sont définis par des languettes 32, 32a découpées, par emboutissage et de manière équidistante, en bordure 6, 7 des profilés 4, 5.In the embodiment of Figures 3 and 4 , the slots are defined by tabs 32, 32a cut, by stamping and equidistantly, at the edge 6, 7 of the sections 4, 5.

Leur disposition en bordure 6, 7 d'un profilé 4 par rapport à celle en bordure 6, 7 du profilé 5 est similaire à la solution des figures 1 et 2. Plus particulièrement, une fois ces profilés 4, 5 assemblés, lesdites languettes 32, 32a de l'un et l'autre, viennent s'inscrire en quinconce les unes entre les autres, de manière à empêcher le déplacement longitudinal des profilés 4, 5 entre eux. Ainsi, ces languettes 32, 32a se croisent à hauteur d'une ligne se situant sensiblement dans le plan médian 31 de la lame 1.Their arrangement at the edge 6, 7 of a profile 4 relative to that at the edge 6, 7 of the profile 5 is similar to the solution of the Figures 1 and 2 . More particularly, once these profiles 4, 5 assembled, said tabs 32, 32a of one and the other, are staggered between each other, so as to prevent the longitudinal displacement of the profiles 4, 5 between them. Thus, these tabs 32, 32a intersect at a line substantially in the median plane 31 of the blade 1.

Dans le mode de réalisation des figures 5 et 6 les moyens de blocage 29 et ceux complémentaires 29a sont définis, substantiellement, par les moyens de retenue 16. En somme, les languettes équidistantes 22 définissent les moyens de blocage 29 en bordure longitudinale 6, 7 des profilés métalliques 4, 5, tandis que les ouvertures discontinues 21 correspondent aux moyens de blocage complémentaires 29a associés, dans ce cas, au profilé de verrouillage 12, 13, ces ouvertures 21 recevant lesdites languettes 22. Ainsi, l'immobilisation en translation axiale des profilés 4, 5 est assurée indirectement au travers de ces profilés de verrouillage 12, 13.In the embodiment of Figures 5 and 6 the blocking means 29 and the complementary means 29a are defined, substantially, by the retaining means 16. In short, the equidistant tongues 22 define the locking means 29 along the longitudinal edge 6, 7 of the metal sections 4, 5, while the discontinuous openings 21 correspond to the complementary blocking means 29a associated, in this case, to the locking profile 12, 13, these openings 21 receiving said tongues 22. Thus, the immobilization in axial translation of the sections 4, 5 is ensured. indirectly through these locking profiles 12, 13.

On comprendra, évidemment, que l'un ou l'autre mode de réalisation décrit précédemment peut se retrouver indifféremment à hauteur du chant supérieur 8 et/ou inférieur 9 de la lame 1.It will be understood, of course, that one or the other embodiment described above can be found indifferently at the height of the upper edge 8 and / or lower 9 of the blade 1.

Autrement dit, les profilés métalliques 4, 5 peuvent être rendus jointifs au niveau de l'un de leur bord longitudinal 6 au travers d'une conception correspondant au mode de réalisation de la figure 1 et à hauteur de leur bord longitudinal opposé 7 à l'aide d'une solution correspondant au mode de réalisation des figures 3, 4 ou 5, 6, tout comme une combinaison des modes de réalisation des figures 3, 4, d'une part, et 5, 6, d'autre part, est envisageable.In other words, the metal sections 4, 5 can be made joined at one of their longitudinal edge 6 through a design corresponding to the embodiment of the figure 1 and at their opposite longitudinal edge 7 by means of a solution corresponding to the embodiment of the Figures 3, 4 or 5, 6 , just like a combination of the embodiments of the Figures 3, 4 , on the one hand, and 5, 6, on the other hand, is conceivable.

Selon une autre particularité de l'invention, au moins l'un des profilés de verrouillage 12, 13 conçoit un joint d'étanchéité à hauteur du chant supérieur 8 ou inférieur 9 de la lame 1, ceci de manière à créer une certaine étanchéité à l'air ou à l'eau entre deux lames 1 superposées. En particulier, comme cela apparaît dans les figures 1 et 3, l'embase 15 d'un profilé de verrouillage 12, 13 peut recevoir, sur son côté opposé à la lame 14, un bossage 33 concevant, substantiellement, ce joint d'étanchéité. Ce bossage 33 peut être défini en un matériau souple. Tout particulièrement, ce bossage 33 peut résulter d'une co-extrusion ou d'un moulage de deux matières synthétiques se distinguant précisément au travers de leur souplesse.According to another feature of the invention, at least one of the locking profiles 12, 13 designs a seal at the height of the upper edge 8 or lower 9 of the blade 1, so as to create a certain seal at air or water between two blades 1 superimposed. In particular, as it appears in the Figures 1 and 3 , the base 15 of a locking profile 12, 13 can receive, on its side opposite the blade 14, a boss 33 designing, substantially, this seal. This boss 33 can be defined in a flexible material. In particular, this boss 33 may result from coextrusion or molding of two synthetic materials distinguished precisely through their flexibility.

Comme il est plus particulièrement remarquable dans les modes de réalisation correspondant aux figures 1 à 6, dans la lame 1, entre les parois 2 et 3, peut prendre position un matériau isolant 11.As is more particularly remarkable in the embodiments corresponding to the Figures 1 to 6 , in the blade 1, between the walls 2 and 3, can take position an insulating material 11.

S'il était d'usage, jusqu'à présent, d'injecter sous forme d'une mousse expansée ce matériau isolant lors du profilage de la lame 1, l'assemblage, par l'intermédiaire de profilés de verrouillage 12, 13 des profilés métalliques 4, 5 formant les parois avant 2 et arrière 3 de la lame 1, autorise l'insertion, entre ces profilés 4, 5, de ce matériau isolant 11 sous forme d'une bande 39 de section adaptée à l'espace interne que viennent délimiter lesdits profilés 4, 5 après assemblage.If it was customary, until now, to inject in the form of an expanded foam this insulating material during the profiling of the blade 1, the assembly, by means of locking profiles 12, 13 of the metal sections 4, 5 forming the front walls 2 and rear 3 of the blade 1, allows the insertion, between these sections 4, 5, of this insulating material 11 in the form of a band 39 of section adapted to the internal space delimited said profiles 4, 5 after assembly.

L'avantage d'une telle solution consiste en ce que l'on peut s'affranchir des contraintes d'injection souvent difficiles à maîtriser.The advantage of such a solution is that one can overcome the constraints of injection often difficult to control.

En effet, une injection de matière trop importante produit le gonflement de la lame, tandis qu'une injection insuffisante rend inopérant, tout du moins réduit les caractéristiques acoustiques et mécaniques recherchées.Indeed, too much material injection produces the swelling of the blade, while insufficient injection makes inoperative, at least reduces the desired acoustic and mechanical characteristics.

En outre, une mousse en injectée adhère nécessairement aux parois internes de la lame, rendant impossible, du moins difficile, le recyclage de celle-ci en fin de vie. En comparaison, l'engagement d'une bande 39 d'un matériau isolant, permet aisément de retirer celle-ci après dégagement des profilés de verrouillage pour séparer le métal du plastique en vue du recyclage.In addition, an injected foam necessarily adheres to the inner walls of the blade, making it impossible, at least difficult, the recycling thereof at the end of life. In comparison, the engagement of a strip 39 of an insulating material makes it easy to remove the latter after disengagement of the locking profiles to separate the metal from the plastic for recycling.
