Elle concerne plus précisément encore une pièce de liaison de deux éléments profilés transversaux, tels que des traverse et montant d'une structure d'encadrement.It also relates more precisely to a connecting piece of two transverse profiled elements, such as crosspieces and uprights of a framing structure.

Le but principal de la présente invention est de perfectionner les dispositions décrites dans le brevet FR-A-2 570 770 au nom de la Demanderesse. Selon ce brevet antérieur, on a prévu d'assembler deux éléments profilés transversaux tels que des traverse et montant d'une structure d'encadrement, pour la mise en oeuvre du procédé qui consiste à engager dans des chambres longitudinales ménagées dans des premiers profilés par les extrémités de ceux-ci, des moyens de blocage prévus en saillie sur le corps principal d'une pièce de liaison, lesdits moyens de blocage présentant une section droite d'enveloppe généralement complémentaire desdites chambres pour assurer une immobilisation relative de chaque pièce de liaison et des premiers profilés, transversalement à la direction d'introduction des moyens de blocage dans la chambre associée, le corps principal desdites pièces de liaison comprenant par ailleurs des moyens de fixation en saillie sur le corps principal, transversalement aux moyens de blocage, les moyens de fixation comprenant des moyens de positionnement aptes à pénétrer dans une rainure longitudinale des seconds profilés, et des moyens d'immobilisation, puis à installer en position une pluralité de seconds profilés généralement parallèles, à introduire ensuite les premiers profilés équipés de pièces de liaison entre des seconds profilés adjacents, transversalement à la direction d'élongation de ces derniers, selon un mouvement relatif perpendiculaire aux directions d'élongation des premiers et seconds profilés, et introduire les moyens de positionnement dans la rainure associée des seconds profilés, et enfin à fixer les pièces de liaison en position choisie grâce aux moyens d'immobilisation.The main object of the present invention is to improve the arrangements described in patent FR-A-2,570,770 in the name of the Applicant. According to this prior patent, provision has been made to assemble two transverse profiled elements such as crosspieces and uprights of a framing structure, for the implementation of the method which consists in engaging in longitudinal chambers formed in first profiles by the ends of these, blocking means provided projecting from the main body of a connecting piece, said blocking means having a cross section of envelope generally complementary to said chambers to ensure relative immobilization of each connecting piece and first profiles, transverse to the direction of introduction of the blocking means into the associated chamber, the main body of said connecting pieces further comprising fixing means projecting from the main body, transversely to the blocking means, the means fastening device comprising positioning means capable of penetrating a longitudinal groove the second profiles, and immobilization means, then to install in position a plurality of second generally parallel profiles, then to introduce the first profiles equipped with connecting pieces between adjacent second profiles, transverse to the direction of elongation these, according to a relative movement perpendicular to the directions of elongation of the first and second profiles, and introduce the positioning means into the associated groove of the second profiles, and finally to fix the connecting pieces in the chosen position thanks to the immobilization means.

L'invention décrite dans ce brevet concerne également une pièce de liaison adaptée à la mise en oeuvre de ce procédé, comprenant un corps de base muni de moyens de blocage en saillie sur le corps, destinés à pénétrer dans au moins une chambre de l'un des éléments profilés et présentant une section droite d'enveloppe généralement complémentaire de ladite chambre pour assurer une immobilisation relative de la pièce de liaison et du profilé transversalement à la direction d'introduction des moyens de blocage dans la chambre, et de moyens de fixation en saillie sur le corps transversalement aux moyens de blocage, les moyens de fixation comprenant des moyens de positionnement aptes à pénétrer dans une rainure du second profilé et des moyens d'immobilisation aptes à bloquer les moyens de fixation et donc la pièce de liaison sur le second profilé dans une position choisie.The invention described in this patent also relates to a connecting piece suitable for implementing this method, comprising a base body provided with locking means projecting from the body, intended to penetrate into at least one chamber of the one of the profiled elements and having a cross section of envelope generally complementary to said chamber to ensure relative immobilization of the connecting piece and of the profile transversely to the direction of introduction of the locking means in the chamber, and of fixing means projecting from the body transversely to the locking means, the fixing means comprising positioning means able to penetrate a groove in the second profile and immobilization means able to block the fixing means and therefore the connecting piece on the second profile in a chosen position.

Or, l'expérience montre que cette pièce de liaison requiert, lors de l'assemblage, l'adjonction de différents joints pour donner pleinement satisfaction. Par ailleurs, l'adjonction de ce joint ne peut se faire par temps humide et/ou par temps froid, le plus souvent pour des températures inférieures à 5°C. Cette contrainte est bien dans ce cas gênante.However, experience shows that this connecting piece requires, during assembly, the addition of different joints to give full satisfaction. Furthermore, the addition of this seal cannot be done in wet weather and / or in cold weather, most often for temperatures below 5 ° C. This constraint is indeed troublesome in this case.

La présente invention vise à améliorer la situation en proposant une pièce de liaison de deux éléments profilés transversaux, caractérisée par le fait qu'elle comprend un joint, en matériau élastomère de synthèse, intégré par surmoulage sur le corps de base de la pièce de liaison pour venir en saillie sur une partie au moins de la surface extérieure du corps de base.The present invention aims to improve the situation by proposing a connecting piece of two transverse profiled elements, characterized in that it comprises a seal, made of synthetic elastomer material, integrated by overmolding on the base body of the connecting piece to protrude over at least part of the outer surface of the base body.

Grâce à l'intégration du joint sur le corps de base, la pièce de liaison conforme à la présente invention autorise l'assemblage de structures, par tout temps et sans risque d'oubli ou de malfaçon de l'étanchéité.Thanks to the integration of the seal on the base body, the connecting piece according to the present invention allows the assembly of structures, in any weather and without risk of forgetting or poor sealing.

Selon une caractéristique avantageuse de la présente invention, le corps de base comprend au moins une rainure à bords convergents et le joint est surmoulé dans cette rainure. Ainsi le joint est maintenu en toute sécurité sur le corps de base.According to an advantageous characteristic of the present invention, the base body comprises at least one groove with converging edges and the seal is molded in this groove. Thus the seal is held securely on the base body.

Selon une autre caractéristique avantageuse de la présente invention, le corps de base a la forme générale d'un parallélépipède et le joint constitue une ceinture continue entourant le corps de base.According to another advantageous characteristic of the present invention, the basic body has the general shape of a parallelepiped and the joint constitutes a continuous belt surrounding the basic body.

Selon une autre caractéristique avantageuse de la présente invention, le joint présente, par rapport au corps de base, une hauteur en saillie variable.According to another advantageous characteristic of the present invention, the seal has, relative to the base body, a variable projecting height.

Selon une autre caractéristique de la présente invention, le joint est réalisé en néoprène, tandis que le corps de base est réalisé en zamack.According to another characteristic of the present invention, the seal is made of neoprene, while the base body is made of zamack.

On va dans un premier temps rappeler rapidement la structure de la pièce de liaison définie dans le brevet FR-A-2 570 770, et illustrée sur la figure 1 annexée, la description plus détaillée de ladite pièce pouvant être trouvée dans le texte de ce brevet.We will first quickly recall the structure of the connecting part defined in patent FR-A-2 570 770, and illustrated in Figure 1 attached, the more detailed description of said part can be found in the text of this patent.

Cette pièce de liaison 10 possède un plan de symétrie qui coïncide avec le plan de coupe III-III de la figure 3.This connecting piece 10 has a plane of symmetry which coincides with the section plane III-III of FIG. 3.

La pièce de liaison 10 comprend un corps de base 12 en forme générale de parallélépipède. Le corps de base 12 est délimité par deux surfaces principales 13, 14, deux surfaces secondaires 15, 16 et deux surfaces auxiliaires 17, 18.The connecting piece 10 comprises a base body 12 in the general shape of a parallelepiped. The base body 12 is delimited by two main surfaces 13, 14, two secondary surfaces 15, 16 and two auxiliary surfaces 17, 18.

Les surfaces principales 13 et 14 sont parallèles entre elles et parallèles au plan de symétrie de la pièce. Les surfaces secondaires 15, 16 sont parallèles entre elles et orthogonales aux surfaces principales 13, 14. Les surfaces auxiliaires 17, 18, sont parallèles entre elles et orthogonales, d'une part, aux surfaces principales 13, 14, et, d'autre part, aux surfaces secondaires 15, 16.The main surfaces 13 and 14 are mutually parallel and parallel to the plane of symmetry of the part. The secondary surfaces 15, 16 are mutually parallel and orthogonal to the main surfaces 13, 14. The auxiliary surfaces 17, 18, are mutually parallel and orthogonal, on the one hand, to the main surfaces 13, 14, and, on the other part, to secondary surfaces 15, 16.

La surface auxiliaire 17 est pourvue de trois tenons en saillie 19, 20 et 21. Ces tenons présentent des sections droites complémentaires de chambres associées prévues dans un premier profilé. Ainsi, lorsque les tenons 19, 20, 21 sont engagés dans les chambres associées du premier profilé, ils définissent une immobilisation relative de la pièce de liaison 10 et du profilé transversalement à la direction d'introduction des tenons, soit transversalement aux surfaces principales 13, 14 et aux surfaces secondaires 15, 16.The auxiliary surface 17 is provided with three projecting studs 19, 20 and 21. These studs have complementary cross sections of associated chambers provided in a first profile. Thus, when the pins 19, 20, 21 are engaged in the associated chambers of the first profile, they define a relative immobilization of the connecting piece 10 and of the profile transversely to the direction of insertion of the pins, ie transversely to the main surfaces 13, 14 and to the secondary surfaces 15, 16.

La surface secondaire 15 est munie d'une rainure à bords convergents 22.The secondary surface 15 is provided with a groove with converging edges 22.

La pièce 10 possède de plus une lame 23 rectiligne s'étendant perpendiculairement au plan de symétrie. La lame 23 est raccordée à la surface secondaire 16 par l'intermédiaire d'une structure de liaison 24. La lame 23 est adaptée pour pénétrer dans une rainure ménagée dans un second profilé afin de définir un positionnement relatif précus entre la pièce de liaison 10 et le second profilé précité. La lame 23 est pourvue au voisinage de chacune de ses extrémités d'un alésage oblong 25, 26, destiné à recevoir des éléments d'ancrage, tels que des vis permettant de fixer la pièce 10 sur le second profilé.The part 10 also has a straight blade 23 extending perpendicular to the plane of symmetry. The blade 23 is connected to the secondary surface 16 via a connecting structure 24. The blade 23 is adapted to penetrate a groove formed in a second profile in order to define a relative relative positioning between the connecting piece 10 and the second section mentioned above. The blade 23 is provided in the vicinity of each of its ends with an oblong bore 25, 26, intended to receive anchoring elements, such as screws making it possible to fix the part 10 on the second profile.

Enfin, les surfaces principales 13, 14 sont pourvues de plaques 27, 28 en saillie. Les plaques 27, 28 s'étendent également perpendiculairement au plan de symétrie. Elles sont prévues à proximité de la surface secondaire 15 au niveau de l'arête réalisée entre la surface auxiliaire 18 et les surfaces principales 13 et 14 respectivement. Les plaques 27, 28 sont destinées à reposer contre le second profilé précité. Elles sont pourvues chacune d'un alésage traversant 29, 30 apte à recevoir un élément d'ancrage, tel qu'un rivet.Finally, the main surfaces 13, 14 are provided with protruding plates 27, 28. The plates 27, 28 also extend perpendicular to the plane of symmetry. They are provided near the secondary surface 15 at the edge produced between the auxiliary surface 18 and the main surfaces 13 and 14 respectively. The plates 27, 28 are intended to rest against the aforementioned second profile. They are each provided with a through bore 29, 30 capable of receiving an anchoring element, such as a rivet.

Le corps de base 110 de la pièce de liaison, 100 conforme à la présente invention, illustrée sur les figures 3 à 7, reprend pour l'essentiel les dispositions enseignées par le brevet FR-A-2 570 770, précédemment rappelées, en regard de la figure 1 annexée.The base body 110 of the connecting piece, 100 in accordance with the present invention, illustrated in FIGS. 3 to 7, essentially repeats the provisions taught by patent FR-A-2,570,770, previously recalled, opposite of Figure 1 attached.

Pour cette raison, les éléments essentiels du corps de base 110 illustré sur les figures 2 à 7 seront assortis de références numériques correspondant à celles utilisées sur la figure 1, mais avec adjonction de "100".For this reason, the essential elements of the basic body 110 illustrated in FIGS. 2 to 7 will be accompanied by numerical references corresponding to those used in FIG. 1, but with the addition of "100".

On notera cependant que par rapport au corps de base 10 illustré sur la figure 1, le corps de base 110 illustré sur les figures 2 à 7 comprend des nervures rectilignes 131, 132, 133, 134 et 135 sur les surfaces des tenons 119, 120, 121, s'étendant parallèlement aux surfaces principales 113, 114. Ces nervures s'étendent perpendiculairement à la surface auxiliaire 117. Il est ainsi prévu une nervure 131, 132 sur chacune des faces principales du tenon 119. Il est de plus prévu une paire de nervures, telles que 133, 134, sur chacune des surfaces extérieures des tenons 120, 121.Note, however, that with respect to the base body 10 illustrated in FIG. 1, the base body 110 illustrated in FIGS. 2 to 7 comprises rectilinear ribs 131, 132, 133, 134 and 135 on the surfaces of the studs 119, 120 , 121, extending parallel to the main surfaces 113, 114. These ribs extend perpendicular to the auxiliary surface 117. There is thus provided a rib 131, 132 on each of the main faces of the stud 119. There is also provided a pair of ribs, such as 133, 134, on each of the outer surfaces of the studs 120, 121.

Les nervures 131 à 135 facilitent l'adaptation des tenons 119, 120, 121 à l'intérieur des chambres associées du premier profilé pour interdire tout jeu entre ces éléments.The ribs 131 to 135 facilitate the adaptation of the pins 119, 120, 121 inside the associated chambers of the first profile to prevent any play between these elements.

En outre, le corps de base 110 illustré sur les figures 2 à 7 se distingue du corps de base 10 illustré sur la figure 1, par le fait que la surface auxiliaire 118 est pourvue d'une rainure droite longitudinale 136, que le fond de la rainure 122 à bords convergents est creusée d'un canal 137 et que la surface secondaire 16 est munie également d'une rainure droite longitudinale 138. Tous ces éléments présentent une symétrie par rapport au plan de coupe III-III.In addition, the base body 110 illustrated in FIGS. 2 to 7 differs from the base body 10 illustrated in FIG. 1, by the fact that the auxiliary surface 118 is provided with a straight longitudinal groove 136, that the bottom of the groove 122 with converging edges is hollowed out with a channel 137 and that the secondary surface 16 is also provided with a straight longitudinal groove 138. All of these elements have symmetry with respect to the section plane III-III.

En outre, comme indiqué précédemment, dans le cadre de la présente invention, la pièce de liaison 100 est pourvue d'un joint 150. Ce joint 150 est réalisé en matériau élastomère de synthèse, par exemple en néoprène. Il est intégré par surmoulage sur le corps de base 110 pour venir en saillie sur une partie au moins de la surface extérieure du corps de base. Ce dernier est avantageusement réalisé en zamack, c'est-à-dire en un alliage base de zinc contenant au maximum 12% d'aluminium et de cuivre. Le surmoulage du joint 150 en néoprène sur le corps de base 110 en zamack est de préférence réalisé à une température de l'ordre de 200°C. La Demanderesse a déterminé que, à cette température, le corps de base 110 de la pièce de liaison ne subissait aucune détérioration et conservait toutes ses propriétés mécaniques.In addition, as indicated above, in the context of the present invention, the connecting piece 100 is provided with a seal 150. This seal 150 is made of synthetic elastomeric material, for example neoprene. It is integrated by overmoulding on the base body 110 to protrude over at least part of the outer surface of the base body. This last is advantageously made of zamack, that is to say of a zinc base alloy containing a maximum of 12% of aluminum and copper. The overmolding of the seal 150 in neoprene on the base body 110 in zamack is preferably carried out at a temperature of the order of 200 ° C. The Applicant has determined that, at this temperature, the base body 110 of the connecting piece does not undergo any deterioration and retains all its mechanical properties.

Plus précisément encore, de préférence, le joint 150 est surmoulé sur le corps 110 sous forme d'une ceinture continue entourant le corps de base 110 au niveau des surfaces secondaires 115, 116 et des surfaces auxiliaires 117, 118. Le joint 150 est ainsi engagé dans la rainure à bords convergents 122 et le canal 137 prévu sur la surface secondaire 115, dans la rainure 136 prévue sur la surface auxiliaire 118, dans la rainure 138 prévue sur la surface secondaire 116; le joint 150 est également disposé de part et d'autre des tenons 119, 120 et 121. Grâce à l'engagement ainsi défini entre le joint surmoulé 150 et le structures du corps de base 110, le joint 150 est immobilisé en toute sécurité sur le corps de base 110.More precisely still, preferably, the seal 150 is molded onto the body 110 in the form of a continuous belt surrounding the base body 110 at the secondary surfaces 115, 116 and the auxiliary surfaces 117, 118. The seal 150 is thus engaged in the groove with converging edges 122 and the channel 137 provided on the secondary surface 115, in the groove 136 provided on the auxiliary surface 118, in the groove 138 provided on the secondary surface 116; the seal 150 is also arranged on either side of the studs 119, 120 and 121. Thanks to the engagement thus defined between the overmolded seal 150 and the structures of the base body 110, the seal 150 is immobilized securely on the base body 110.

Comme cela apparaît clairement à l'examen des figures annexées, le joint 150 présente de préférence, par rapport au corps de base 110, une hauteur en saillie variable. Cette hauteur du joint 150 dépassant du corps de base 110 est adaptée, en fonction de la géométrie des profilés à relier, pour assurer une étanchéité optimale.As is clear from examining the appended figures, the seal 150 preferably has, relative to the base body 110, a variable projecting height. This height of the joint 150 protruding from the base body 110 is adapted, as a function of the geometry of the profiles to be connected, to ensure optimum sealing.

Le joint 150 est réalisé en plaçant le corps de base 110 dans un moule définissant sur la périphérie des surfaces secondaires 115, 116 et des surfaces auxiliaires 117, 118, une chambre continue complémentaire du joint 150 recherché.The seal 150 is produced by placing the base body 110 in a mold defining on the periphery of the secondary surfaces 115, 116 and of the auxiliary surfaces 117, 118, a continuous chamber complementary to the seal 150 sought.

Le joint 150 peut faire l'objet de nombreux modes de réalisation.The seal 150 can be the subject of many embodiments.

Selon un mode de réalisation représenté sur les figures annexées, ce joint 150 comprend une bande 151 engagée dans la rainure 136 et de même largeur que celle-ci. La bande 151 présente une hauteur en saillie constante par rapport à la surface auxiliaire 118. La bande 151 se prolonge vers la surface auxiliaire 116 par une bande étagée 152 qui recouvre la zone de liaison 124 et la lame 123, en présentant, par rapport au corps de base 110, la même hauteur en saillie que la bande 151. La bande 152 se prolonge par une bande 153 engagée dans la rainure 138 et présentant de préférence une plus faible largeur que la bande 151. Le cas échéant, la bande 153 peut être pourvue d'une protubérance 154 adaptée pour pénétrer dans une rainure associée ménagée dans le second profilé.According to an embodiment shown in the appended figures, this seal 150 comprises a strip 151 engaged in the groove 136 and of the same width as the latter. The strip 151 has a constant projecting height relative to the auxiliary surface 118. The strip 151 is extended towards the auxiliary surface 116 by a stepped strip 152 which covers the connection zone 124 and the blade 123, presenting, with respect to the base body 110, the same projecting height as the strip 151. The strip 152 is extended by a strip 153 engaged in the groove 138 and preferably having a narrower width than the strip 151. If necessary, the strip 153 can be provided with a protrusion 154 adapted to penetrate an associated groove formed in the second profile.

La bande 153 se prolonge sur la surface auxiliaire 117 par une bande 155. De préférence, la bande 155 est pourvue de lèvres 158, 159 sur chacun de ses bords libres longitudinaux 156, 157 parallèles aux surfaces principales 113, 114. Les lèvres 158, 159 sont planes. Elles s'étendent parallèlement aux surfaces 113, 114. Leur distance est sensiblement égale à la largeur du premier profilé destiné à recevoir les tenons 119, 120, 121. Ainsi, lorsque les tenons 119, 120, 121 sont engagés dans le premier profilé, les lèvres 158, 159 sont placées sur l'extérieur du premier profilé pour parfaire l'étanchéité du système.The strip 153 is extended on the auxiliary surface 117 by a strip 155. Preferably, the strip 155 is provided with lips 158, 159 on each of its longitudinal free edges 156, 157 parallel to the main surfaces 113, 114. The lips 158, 159 are flat. They extend parallel to the surfaces 113, 114. Their distance is substantially equal to the width of the first profile intended to receive the studs 119, 120, 121. Thus, when the studs 119, 120, 121 are engaged in the first profile, the lips 158, 159 are placed on the outside of the first profile to perfect the sealing of the system.

On a illustré schématiquement, en traits interrompus, un premier profilé, sous la référence P, sur la figure 4. La bande 155 entoure la base des tenons 119, 120, 121.A first profile is shown schematically, in broken lines, under the reference P, in FIG. 4. The strip 155 surrounds the base of the studs 119, 120, 121.

Enfin, les bande 155 se prolonge au niveau de la surface secondaire 115 par l'intermédiaire d'une bande 160. La bande 160 est elle-même reliée à la bande 151 précitée. Elle est engagée dans la rainure à bords convergents 122. Le cas échéant, comme cela apparaît notamment à l'examen des figures 3 et 5, la bande 160 peut être étagée, c'est-à-dire présenter une hauteur en saillie variable par rapport à la surface secondaire 115.Finally, the strip 155 extends at the level of the secondary surface 115 by means of a strip 160. The strip 160 is itself connected to the strip 151 above. It is engaged in the groove with converging edges 122. Where appropriate, as appears in particular on examining FIGS. 3 and 5, the strip 160 can be stepped, that is to say have a projecting height varying by relative to the secondary surface 115.

L'assemblage de profilés transversaux à l'aide de la pièce de liaison 100 conforme à la présente invention reste identique au processus décrit dans le brevet FR-A-2 570 770.The assembly of transverse profiles using the connecting piece 100 according to the present invention remains identical to the process described in patent FR-A-2,570,770.

Cependant, l'intégration d'un joint 150 sur le corps de base évite toute adjonction ultérieure de joints nécessaires, permet l'assemblage des profilés par tout temps, c'est-à-dire quels que soient la température et le degré d'humidité, enfin évite tout oubli et toute malfaçon de l'étanchéité.However, the integration of a seal 150 on the base body avoids any subsequent addition of necessary seals, allows the assembly of the profiles in any weather, that is to say whatever the temperature and the degree of humidity, finally avoids any forgetting and any faulty sealing.
