Abstract

The assembly has a section (100) e.g. strut, with preformed projections (110, 120) of grooves (111, 121) that are in connection with a part of a joint (300), where another part of the joint is in contact with another section (200) e.g. strut. The former part of the joint is flexible than a part supporting the latter section so that the translation of parts of the sections due to variation of dimension has effect on volume of the former part of the joint. The former part of the joint is under-dimensioned with respect to a hollow volume of one of the grooves.

Description

DOMAINE D'APPLICATION DE L'INVENTIONFIELD OF APPLICATION OF THE INVENTION

La présente invention a trait au domaine des assemblages de menuiserie et notamment aux adaptations permettant de prendre en compte les conséquences du phénomène de la dilatation lorsque les éléments assemblés ne sont pas parallèles.The present invention relates to the field of woodwork assemblies and especially to adaptations to take into account the consequences of the phenomenon of expansion when the assembled elements are not parallel.

DESCRIPTION DE L'ART ANTÉRIEURDESCRIPTION OF THE PRIOR ART

L'invention concerne les assemblages de menuiserie comprenant un emboîtement. Une liaison par emboîtement requiert que le jeu nécessaire à la mise en place des éléments devant s'emboîter soit minimal pour que la liaison soit rigide et monolithique. Ainsi, les liaisons souples ne sont pas concernées par l'invention.The invention relates to joinery assemblies comprising an interlocking. An interlocking connection requires that the clearance required for the insertion of the elements to be interlocked is minimal so that the connection is rigid and monolithic. Thus, the flexible connections are not concerned by the invention.

Un tel emboîtement est connu notamment dans l'assemblage nécessairement rigide des cadres des éléments unitaires vitrés formant un mur-rideau.Such interlocking is known in particular in the necessarily rigid assembly of the frames of the glazed unitary elements forming a curtain wall.

Dans de tels assemblages, il est possible que les éléments constitutifs ne soient pas dans le même plan, ce qui est connu par exemple dans le domaine des murs-rideaux lorsque les façades présentent des angles. Le phénomène de dilatation, c'est à dire la variation des dimensions des éléments participant à l'assemblage due aux variations de température, n'est pas égal dans toutes les directions et est susceptible de voir ses effets principaux s'appliquer selon un axe non parallèle à l'axe d'emboîtement des éléments.In such assemblies, it is possible that the constituent elements are not in the same plane, which is known for example in the field of curtain walls when the facades have angles. The phenomenon of expansion, ie the variation of the dimensions of the elements involved in the assembly due to temperature variations, is not equal in all directions and is likely to have its main effects applied along an axis not parallel to the interlocking axis of the elements.

L'assemblage pourrait alors être fragilisé ou voir son étanchéité compromise.The assembly could then be weakened or compromised.

Cet inconvénient est d'autant plus difficile à gérer que les profilés à assembler sont susceptibles de rester orientés de la même façon alors que les unités auxquelles ils appartiennent ne sont pas orientées selon le même angle.This disadvantage is all the more difficult to manage that the profiles to be assembled are likely to remain oriented in the same way while the units to which they belong are not oriented according to the same angle.

De même, lorsque l'assemblage ou les profilés sont préformés pour prévoir une orientation de la dilatation différente de celle de l'assemblage, la variabilité volontairement recherchée des fixations angulaires dans les différents assemblages ne permet pas d'obtenir dans tous les cas une préformation correspondant à la déformation.Similarly, when the assembly or the profiles are preformed to provide an orientation of the expansion different from that of the assembly, the deliberately desired variability of the angular fasteners in the different assemblies does not allow to obtain in all cases a pre-formation corresponding to the deformation.

Le document EP 0436868 décrit une ossature pour une paroi de façade présentant des assemblages de montants et de traverses susceptible de présenter les inconvénients ci-dessus cités. En effet, ce document décrit un assemblage de type emboîtement rigide comportant des parties susceptibles de se dilater dans des directions différentes, ledit assemblage comprenant au moins deux profilés s'emboîtant l'un dans l'autre et au moins un joint s'interposant entre les deux,
un premier profilé comportant au moins une projection préformée d'une gorge de fixation d'une première partie du joint dont la deuxième partie présente une première surface d'appui contre le premier profilé de part et d'autre de la gorge de fixation et une deuxième surface d'appui entrant en contact avec le deuxième profilé lors de l'emboîtement,
le deuxième profilé comportant une surface d'appui pour ledit joint.The document EP 0436868 discloses a frame for a facade wall having assemblies of uprights and crosspieces likely to have the disadvantages mentioned above. Indeed, this document describes a rigid interlocking type assembly comprising parts capable of expanding in different directions, said assembly comprising at least two sections fitting one into the other and at least one seal interposing between both,
a first section comprising at least one preformed projection of a groove for fixing a first portion of the seal, the second part of which has a first bearing surface against the first section on either side of the fixing groove and a second bearing surface coming into contact with the second profile during nesting,
the second section having a bearing surface for said seal.

Comme expliqué plus haut, le phénomène de dilatation, c'est à dire la variation des dimensions des éléments participant à l'assemblage due aux variations de température, peut s'appliquer selon un axe non parallèle à l'axe d'emboîtement des éléments. Une telle variation est prise en compte par la souplesse de la deuxième partie, c'est à dire par la partie extérieure du joint, qui se retrouve comprimée entre le premier profilé et le deuxième lors de emboîtement rigide. Cette prise en compte n'est pas optimale du fait du peu d'élasticité disponible dans cette partie de joint qui doit par ailleurs autoriser l'emboîtement.As explained above, the phenomenon of expansion, that is to say the variation of the dimensions of the elements involved in the assembly due to temperature variations, can be applied along an axis not parallel to the axis of interlocking elements. . Such variation is taken into account by the flexibility of the second part, that is to say by the outer part of the seal, which is found compressed between the first section and the second during rigid interlocking. This consideration is not optimal because of the lack of elasticity available in this part of joint which must moreover allow the interlocking.

En outre, le fait que les surfaces des profilés en contact avec le joint soient planes et parallèles n'autorise pas la prise en compte d'une variation dans l'angle d'assemblage entre les profilés devant s'emboîter.In addition, the fact that the surfaces of the profiles in contact with the joint are flat and parallel does not allow the consideration of a variation in the angle of assembly between the profiles to be fitted.

DESCRIPTION DE L'INVENTIONDESCRIPTION OF THE INVENTION

Ce que constatant, la demanderesse a mené des recherches visant à obvier aux inconvénients précités aussi bien pour des assemblages par emboîtement de type de ceux susceptibles de se retrouver dans les murs-rideaux que ceux se trouvant d'une manière générale dans la menuiserie.What is clear, the applicant has conducted research to obviate the aforementioned drawbacks as well for type interlocking assemblies of those likely to end up in the curtain walls that are generally in the carpentry.

L'assemblage de type emboîtement rigide de l'invention comporte des parties susceptibles de se dilater selon des directions différentes,
ledit assemblage comprenant au moins deux profilés s'emboîtant l'un dans l'autre et au moins un joint s'interposant entre les deux,
un premier profilé comportant au moins une projection préformée d'une gorge pour être en liaison une première partie du joint dite partie intérieure, dont l'autre partie dite partie extérieure, vient en contact avec le deuxième profilé,
le deuxième profilé comportant une surface d'appui pour ledit joint.The rigid interlocking type assembly of the invention comprises parts that can expand in different directions,
said assembly comprising at least two sections fitting one into the other and at least one seal interposed between the two,
a first profile comprising at least one preformed projection of a groove to be connected to a first part of the so-called inner part seal, the other part of which said outer part comes into contact with the second section,
the second section having a bearing surface for said seal.

Conformément à l'invention, la partie de joint en liaison avec la gorge du premier profilé est, une fois montée, plus souple que celle venant en appui avec le deuxième profilé, cette partie extérieure du joint n'étant pas en contact avec la projection du premier profilé, de sorte que la translation des parties des profilés due à la variation des dimensions due à la dilatation ait un effet sur le volume de la partie de joint logée dans ladite gorge.According to the invention, the joint portion in connection with the groove of the first section is, once mounted, more flexible than that coming into abutment with the second section, this outer part of the joint not being in contact with the projection the first section, so that the translation of the profile parts due to the variation in dimensions due to expansion has an effect on the volume of the seal portion housed in said groove.

Ainsi, c'est à l'intérieur de la gorge que se produit la déformation et non à l'extérieur. Le joint peut être écrasé mais c'est la partie logée qui va alors se dilater ou se compresser.Thus, it is inside the throat that occurs the deformation and not on the outside. The seal can be crushed but it is the housed part that will then expand or compress.

Ce principe est contraire à ceux jusqu'ici développés. En effet, le principe habituel de fonctionnement d'un joint utilise une gorge à clipper ou à bourrer servant de « pied de maintien » du joint et de générer à l'extérieur de cette gorge, la fonction propre au joint.This principle is contrary to those hitherto developed. Indeed, the usual principle of operation of a seal uses a throat clipper or stuffing serving as "support foot" of the seal and generate outside this groove, the function of the joint.

L'assemblage de l'invention, en proposant de déformer la partie intérieure du joint associée à la gorge de maintien, inverse le principe jusqu'ici utilisé.The assembly of the invention, by proposing to deform the inner portion of the seal associated with the holding groove, reverses the principle heretofore used.

Un travail à l'intérieur de la gorge crée de l'espace pour permettre les phénomènes de compression et de décompression lorsque les deux éléments à assembler sont très proches l'un de l'autre.
Par exemple, dans le cas d'une façade de type mur-rideau utilisant le principe unitaire, la distance entre le profil mâle et le profil femelle est très faible.
Une technique classique de joint ne permettrait pas d'obtenir, sur un si petit écartement, un maintien et une étanchéité continue entre les profils au gré de la dilatation. Il faudrait écarter beaucoup plus les profils. De ce fait, l'élasticité extérieure du joint entre les deux demi-profils ne permettrait plus de garantir soit la pénétration correcte, soit le maintien monolithique.
Le fait d'inverser le principe du joint (fonction à l'intérieur de la gorge et non à l'extérieur) permet de plus de gagner de l'élasticité sur le système car la masse du joint est plus importante tout en permettant une pénétration sans risque d'arrachement lors de la mise en oeuvre.A work inside the throat creates space to allow compression and decompression phenomena when the two elements to be assembled are very close to each other.
For example, in the case of a curtain wall type facade using the unitary principle, the distance between the male profile and the female profile is very small.
A conventional joint technique would not obtain, on such a small spacing, a maintenance and a continuous seal between the profiles at the option of expansion. We should discard the profiles much more. As a result, the external elasticity of the joint between the two half-profiles no longer makes it possible to guarantee either the correct penetration or the monolithic maintenance.
The fact of inverting the principle of the seal (function inside the groove and not outside) makes it possible to gain more elasticity on the system because the mass of the seal is larger while permitting penetration without risk of tearing during the implementation.

Selon une autre caractéristique particulièrement avantageuse de l'invention, la partie du joint logée dans ladite gorge est sous-dimensionnée par rapport au volume vide de la gorge afin d'autoriser son expansion. Ainsi lors de la compression du joint la partie logée dans la gorge va remplir le volume laissé libre à cet effet.According to another particularly advantageous feature of the invention, the portion of the seal housed in said groove is undersized with respect to the empty volume of the groove in order to allow its expansion. So when compressing the seal the portion housed in the groove will fill the volume left free for this purpose.

Selon une autre caractéristique particulièrement avantageuse de l'invention, la partie de joint logée dans la gorge présente un profil fonctionnant sur un effet de ressort grâce à une certaine dureté Shore déterminée en fonction de la réaction souhaitée. La masse cylindre dans la gorge se compresse ou se décompresse alors en fonction des mouvements des profils, comme une balle lorsque comme proposé par une caractéristique de l'invention, ledit profil est cylindrique.According to another particularly advantageous feature of the invention, the seal portion housed in the groove has a profile operating on a spring effect due to a certain Shore hardness determined according to the desired reaction. The cylinder mass in the groove then compresses or decompresses according to the movements of the profiles, as a bullet when as proposed by a feature of the invention, said profile is cylindrical.

Selon une autre caractéristique particulièrement avantageuse, la partie extérieure du joint est constituée par une lèvre qui, quel que soit le taux de compression de la partie intérieure, suit le profil avec lequel elle est en contact, pour en assurer l'étanchéité.According to another particularly advantageous characteristic, the outer portion of the seal is constituted by a lip which, whatever the compression ratio of the inner part, follows the profile with which it is in contact, to ensure sealing.

Selon une autre caractéristique particulièrement avantageuse de l'invention, la partie du deuxième profilé servant de surface d'appui audit joint adopte un profil arrondi, l'arc dudit arrondi présentant un axe parallèle à l'axe d'orientation angulaire d'un profilé par rapport à l'autre.According to another particularly advantageous feature of the invention, the portion of the second profile serving as a support surface for said seal adopts a rounded profile, the arc of said rounded having an axis parallel to the axis of angular orientation of a profile compared to each other.

Selon une autre caractéristique particulièrement avantageuse, ladite gorge est préformée de rebords dont l'écartement assure le pincement du profilé de la première partie du joint de façon à former un étranglement participant d'une part à la tenue du joint mais autorisant d'autre part le passage d'une partie du volume de cette partie du joint à l'intérieur ou à l'extérieur de la gorge selon le rapprochement ou l'éloignement des projections.According to another particularly advantageous characteristic, said groove is preformed with flanges whose spacing ensures the nip of the profile of the first part of the seal so as to form a constriction participating on the one hand in holding the seal but allowing on the other hand the passage of a portion of the volume of this portion of the seal inside or outside the groove as the approximation or distance projections.

Selon une autre caractéristique particulièrement avantageuse de l'invention, le joint se décompose en trois parties :

  • une première partie intérieure venant se loger dans la gorge,
  • une deuxième partie extérieure venant en contact avec le deuxième profilé et
  • une troisième partie assurant la liaison entre les deux, la longueur de cette troisième partie garantissant une fois les profilés emboîtés, une possibilité de déplacement en translation, du joint à l'intérieur de la gorge.
According to another particularly advantageous characteristic of the invention, the seal is broken down into three parts:
  • a first inner part coming to lodge in the throat,
  • a second outer part coming into contact with the second section and
  • a third part ensuring the connection between the two, the length of this third part once ensuring the nested sections, a possibility of displacement in translation, the seal inside the groove.

Selon une autre caractéristique particulièrement avantageuse, ladite partie intérieure du joint comprend un profil supérieur garantissant l'emprisonnement dans la gorge et un profil inférieur élastique servant de module élastique de mise en tension du joint tendant à faire sortir le joint hors de la gorge et mis en compression lors de l'emboîtement.According to another particularly advantageous feature, said inner portion of the seal comprises an upper profile ensuring the imprisonment in the groove and a lower elastic profile serving as an elastic modulus for tensioning the joint tending to pull the seal out of the groove and put in compression during nesting.

L'invention concerne également l'élément de mur-rideau dont les profilés de montants et ou de traverses adopte une ou plusieurs des caractéristiques ci-dessus décrites.The invention also relates to the curtain wall element whose profiles amounts and or crosses adopts one or more of the characteristics described above.

Les concepts fondamentaux de l'invention venant d'être exposés ci-dessus dans leur forme la plus élémentaire, d'autres détails et caractéristiques ressortiront plus clairement à la lecture de la description qui suit et en regard des dessins annexés, donnant à titre d'exemple non limitatif, un mode de réalisation d'un assemblage conforme à l'invention.The basic concepts of the invention having been described above in their most elementary form, other details and characteristics will emerge more clearly on reading the description which follows and with reference to the appended drawings, giving non-limiting example, an embodiment of an assembly according to the invention.

DESCRIPTION DES MODES DE RÉALISATION PRÉFÉRÉSDESCRIPTION OF THE PREFERRED EMBODIMENTS

Tel qu'illustré sur le dessin de la figure 1, l'assemblage concerne deux montants 100 et 200 de deux châssis C1 et C2 encadrant associés à des traverses T1 et T2 par exemple deux surfaces vitrées (non illustrées). Comme illustrées, les traverses T1 et T2 et en conséquence les deux surfaces vitrées appartenant respectivement aux châssis C1 et C2 ne sont pas dans le même plan, configuration connue d'une façade à facettes (présentant des angles) formée par un mur-rideau exploitant la technique de l'assemblage d'éléments unitaires pré-assemblés.As illustrated on the drawing of the figure 1 , the assembly relates to two uprights 100 and 200 of two frames C1 and C2 framing associated with sleepers T1 and T2 for example two glazed surfaces (not shown). As illustrated, the cross members T1 and T2 and consequently the two glazed surfaces respectively belonging to the chassis C1 and C2 are not in the same plane, a known configuration of a faceted facade (with angles) formed by a curtain wall exploiting the technique of assembling pre-assembled unit elements.

Comme expliqué plus haut, un tel assemblage rigide est susceptible de voir les effets de la dilatation s'appliquer selon un axe non parallèle au plan d'assemblage.As explained above, such a rigid assembly is likely to see the effects of the expansion applied along an axis not parallel to the assembly plane.

Pour obvier à ces inconvénients, l'assemblage des profilés 100 et 200 illustré à la figure 2 a été conçu.To overcome these disadvantages, the assembly of the profiles 100 and 200 shown in FIG. figure 2 has been conceived.

Ces profilés 100 et 200 permettent de mettre en oeuvre l'assemblage de l'invention tel celui utilisé pour les montants illustrés sur le dessin de la figure 1.These profiles 100 and 200 make it possible to implement the assembly of the invention such as that used for the amounts illustrated in the drawing of FIG. figure 1 .

Cet assemblage de type emboîtement rigide comportant des parties susceptibles de se dilater selon des directions différentes, comprend deux profilés 100 et 200 s'emboîtant l'un dans l'autre et au moins un joint 300 s'interposant entre les deux.This rigid interlocking type assembly comprising parts capable of expanding in different directions, comprises two sections 100 and 200 fitting one into the other and at least one seal 300 interposed between the two.

Un premier profilé 100 comporte deux projections 110 et 120 préformées d'une gorge 111 et 121 pour être en liaison avec une première partie 310 du joint 300 dont l'autre partie 320 vient en contact avec le deuxième profilé 200. Le deuxième profilé 200 comporte deux projections 210 et 220 venant se positionner entre les deux projections 110 et 120 lors de l'emboîtement et proposant une surface d'appui 211 et 221 pour ledit joint 300.A first profile 100 comprises two projections 110 and 120 preformed with a groove 111 and 121 to be in connection with a first portion 310 of the seal 300, the other portion 320 comes into contact with the second section 200. The second profile 200 comprises two projections 210 and 220 being positioned between the two projections 110 and 120 during the nesting and providing a bearing surface 211 and 221 for said seal 300.

Comme illustrées, les projections 110, 120 et 210, 220 des profilés 100 et 200 s'emboîtant sont sensiblement parallèles au plan d'emboîtement. Le contact dans lequel s'interpose le joint 300 est réalisé linéairement à l'extrémité de ces projections.As illustrated, the projections 110, 120 and 210, 220 of the sections 100 and 200 interlocking are substantially parallel to the interlocking plane. The contact in which the seal 300 interposes is made linearly at the end of these projections.

Comme illustré sur les dessins des figures 3, 4, 5 et 6 et conformément à l'invention, la partie de joint 310 en liaison avec la gorge 111 de la projection 110 du premier profilé 100 est plus souple que celle 320 venant en appui sur la projection 210 du deuxième profilé 200 de sorte que la translation des parties des profilés due à la variation des dimensions due à la dilatation ait un effet sur le volume de la partie 310 de joint logée dans ladite gorge 111.As illustrated in the drawings of figures 3 , 4, 5 and 6 and according to the invention, the joint portion 310 in connection with the throat 111 of the projection 110 of the first profile 100 is more flexible than that 320 bearing against the projection 210 of the second section 200 so that the translation of the parts profiles due to dimensional variation due to expansion have an effect on the volume of the seal portion 310 housed in said groove 111.

Ainsi lorsque comme illustré sur le dessin de la figure 4, le déplacement des profilés tend à les rapprocher, la première partie 310 du joint 300 est compressée et vient se dilater à l'intérieur du volume laissé libre dans la gorge 111. A cet effet, les dimensions de la partie du joint logée dans ladite gorge ne correspondent pas à celle de la gorge et sont sous-dimensionnées par rapport au volume vide de la gorge afin d'autoriser son expansion.So when as illustrated on the drawing of the figure 4 , the displacement of the profiles tends to bring them closer, the first part 310 of the seal 300 is compressed and expands inside the volume left free in the groove 111. For this purpose, the dimensions of the part of the seal housed in said grooves do not correspond to that of the groove and are undersized compared to the empty volume of the groove to allow expansion.

Lorsque, comme illustrés sur les dessins des figures 2, 3 et 5, les profilés restent dans leur position d'emboîtement d'origine, la partie intérieure est suffisamment sous tension pour garantir le contact entre entre les projections 110 et 210.Where, as illustrated in the drawings of figures 2 , 3 and 5 , the profiles remain in their original nesting position, the inner portion is sufficiently energized to ensure the contact between the projections 110 and 210.

Lorsque comme illustré sur le dessin de la figure 6, le déplacement des profilés tend à les éloigner, la première partie 310 du joint se dilate hors de la gorge 111.When as illustrated on the drawing of the figure 6 , the displacement of the profiles tends to move away, the first portion 310 of the seal expands out of the groove 111.

Pour ce faire, la partie de joint 310 logée dans la gorge 111 présente un profil cylindrique pincé par les rebords de ladite gorge 111. Ce pincement forme un étranglement participant à la tenue du joint mais permettant également selon le rapprochement ou l'éloignement (et en conséquence selon la compression ou la libération induites par ces mouvements) des projections de faire passer une partie du volume de cette partie 310 du joint 300 à l'intérieur ou à l'extérieur de la gorge 111.To do this, the joint portion 310 housed in the groove 111 has a cylindrical profile pinched by the edges of said groove 111. This nip forms a constriction participating in the holding of the joint but also allowing, according to the approach or the distance (and consequently according to the compression or the release induced by these movements) projections to pass part of the the volume of this portion 310 of the gasket 300 inside or outside the groove 111.

Selon le mode de réalisation illustré, la partie extérieure 320 du joint 300 est constituée par une lèvre 321 qui, quel que soit le taux de compression de la partie intérieure, suit la projection 210 pour en assurer l'étanchéité. Cette partie n'est pas susceptible d'être compressée mais transmet à la première partie 310 la pression ou la libération dues au rapprochement ou à l'éloignement des parties (les projections) des profilés emboîtés.According to the illustrated embodiment, the outer portion 320 of the gasket 300 is constituted by a lip 321 which, regardless of the compression ratio of the inner part, follows the projection 210 to ensure sealing. This part is not likely to be compressed but transmits to the first part 310 the pressure or release due to the approximation or removal of the parts (the projections) of the nested sections.

Afin d'autoriser le mouvement d'emboîtement et de prévoir une pression ou une libération progressive de la liaison la partie du deuxième profilé servant de surface d'appui audit joint adopte un profil arrondi permettant de garantir la distance entre la gorge du premier profilé et la surface d'appui malgré l'éventuelle rotation d'un profilé par rapport à l'autre.In order to allow the interlocking movement and to provide a pressure or a progressive release of the connection, the portion of the second profile serving as a support surface for said seal adopts a rounded profile making it possible to guarantee the distance between the groove of the first profile and the bearing surface despite the possible rotation of a profile relative to the other.

La figure 7 illustre un autre mode de réalisation de l'assemblage de l'invention avec un joint 300' présentant un profil différent. Comme illustré, ce joint 300' se décompose en trois parties :

  • une première partie intérieure 310' venant se loger dans la gorge 111,
  • une deuxième partie extérieure 320' venant en contact avec le deuxième profilé 200 et
  • une troisième partie 330' assurant la liaison entre les deux parties 310' et 320', la longueur de cette troisième partie garantissant une fois les profilés 100 et 200 emboîtés, une possibilité de déplacement en translation selon la double flèche F1, du joint 300' à l'intérieur de la gorge. Comme illustrée, une fois les deux profilés emboîtés, ni la partie intérieure 310' ni la partie extérieure 320' ne sont en appui contre les bords respectivement intérieurs ou extérieurs de la rainure 112 de la gorge 111 d'accueil du joint 300'.
Figure 7 illustrates another embodiment of the assembly of the invention with a seal 300 'having a different profile. As illustrated, this seal 300 'is divided into three parts:
  • a first inner portion 310 'being received in the groove 111,
  • a second outer part 320 'coming into contact with the second section 200 and
  • a third part 330 'providing the connection between the two parts 310' and 320 ', the length of this third part guaranteeing once the sections 100 and 200 nested, a possibility of translational movement according to the double arrow F1, the seal 300 'inside the groove. As illustrated, once the two sections are engaged, neither the inner part 310 'nor the outer part 320' bear against the inner or outer edges respectively of the groove 112 of the groove 111 of the seal 300 '.

Comme illustrée, ladite partie intérieure 310' du joint 300' comprend un profil supérieur 311' (orienté vers l'ouverture 112 de la gorge 111) garantissant l'emprisonnement dans la gorge 111 en présentant une largeur supérieure à l'étranglement 112 et un profil inférieur 312' élastique (orienté vers le fond de la gorge 111) servant de module élastique de mise en tension du joint 300' tendant à faire sortir le joint 300' hors de la gorge 111 et mis en compression lors de l'emboîtement. Le profil de ce module élastique est selon le mode de réalisation illustré adopte la forme d'un V dont les branches viennent en contact avec le fond de gorge 111 et dont la partie centrale est en liaison avec le profil supérieur 311' du joint, l'élasticité du matériau autorisant le pliage des branches du V lors de l'emboîtement et garantissant la mise en tension.As illustrated, said inner portion 310 'of the gasket 300' comprises an upper profile 311 '(facing the opening 112 of the groove 111) guaranteeing the imprisonment in the groove 111 having a width greater than the throat 112 and a lower profile 312 'elastic (oriented towards the bottom of the groove 111) serving as an elastic modulus for tensioning the seal 300' tending to pull the seal 300 'out of the groove 111 and put in compression during the nesting. The profile of this elastic module is according to the illustrated embodiment adopts the shape of a V whose branches come into contact with the groove bottom 111 and whose central portion is in connection with the upper profile 311 'of the seal, elasticity of the material allowing the folding of the branches of the V during the nesting and guaranteeing the tensioning.

On comprend que l'assemblage, qui vient d'être ci-dessus décrit et représenté, l'a été en vue d'une divulgation plutôt que d'une limitation. Bien entendu, divers aménagements, modifications et améliorations pourront être apportés à l'exemple ci-dessus, sans pour autant sortir du cadre de l'invention.It is understood that the assembly, which has just been described above and shown, has been for the purpose of disclosure rather than limitation. Of course, various arrangements, modifications and improvements may be made to the example above, without departing from the scope of the invention.

Ainsi par exemple, l'assemblage décrit bien que particulièrement adapté à l'assemblage d'éléments de cadres constitutifs de murs-rideaux est prévu également pour l'assemblage d'éléments de menuiserie générale. De plus, bien que le profil cylindrique pour la première partie logée dans la rainure du profilé constitue le mode de réalisation illustré, d'autres profils sont possibles pour assurer cette fonction.For example, the assembly describes that although particularly suitable for the assembly of curtain wall elements constituting elements is also provided for the assembly of general joinery elements. In addition, although the cylindrical profile for the first part housed in the groove of the profile is the illustrated embodiment, other profiles are possible to provide this function.
