Description

La présente invention concerne un système d'assemblage de profilés creux permettant la réalisation de structures portantes.The present invention relates to a system for assembling hollow profiles allowing the production of load-bearing structures.

Les structures portantes ainsi obtenues peuvent former par exemple des échafaudages, des estrades, des plates-formes, des tribunes, etc.. Toutefois, dans une application préférentielle, quoique non exclusive, la structure portante constitue un échafaudage destiné plus particulièrement à l'entretien et au nettoyage d'aéronefs.The supporting structures thus obtained can form, for example, scaffolding, platforms, platforms, platforms, etc. However, in a preferred, although not exclusive, application, the supporting structure constitutes a scaffolding intended more particularly for maintenance and cleaning aircraft.

Généralement, les systèmes d'assemblage de profilés, présentant une section polygonale ou circulaire, comprennent des moyens de liaison composés d'une pluralité d'éléments tels que, par exemple, des brides, raccords, pattes,... et des moyens de fixation immobilisant, de façon appropriée, ces éléments aux profilés à assembler.Generally, profile assembly systems, having a polygonal or circular section, comprise connecting means composed of a plurality of elements such as, for example, flanges, fittings, lugs, ... and means of fixing immobilizing, in an appropriate manner, these elements to the profiles to be assembled.

Selon que les profilés à assembler sont destinés à former entre eux des angles droits (cas le plus fréquent) ou quelconques, on est bien souvent amené à prévoir des moyens de liaison dont les éléments sont spécifiquement adaptés à chacun des angles d'assemblage rencontrés desdits profilés.Depending on whether the profiles to be assembled are intended to form between them right angles (most frequent case) or any, it is often necessary to provide connecting means whose elements are specifically adapted to each of the assembly angles encountered of said profiles.

Il ressort alors que, pour répondre à chaque cas de figure, on doit disposer d'un nombre important d'éléments de liaison.It then appears that, in order to answer each case, a large number of connecting elements must be available.

La présente invention a notamment pour but de remédier à ces inconvénients et concerne un système d'assemblage de profilés dont les moyens de liaison le constituant comprennent un nombre réduit d t éléments, qui peuvent de plus s'adapter aux différents angles d'assemblage rencontrés entre lesdits profilés.The object of the present invention is in particular to remedy these drawbacks and concerns a system for assembling profiles, the connecting means constituting it comprising a reduced number of elements, which can moreover adapt to the different angles of assembly encountered between said profiles.

A cet effet, le système d'assemblage de profilés creux pour la réalisation de structures portantes, du type dans lequel ledit système comporte des moyens de liaison susceptibles de relier deux profilés et des moyens de fixation desdits moyens de liaison respectivement sur lesdits profilés, est remarquable, selon l'invention, en ce que lesdits moyens de liaison comprennent - un premier organe susceptible de coopérer avec le profil extérieur d'un des profilés, en y étant solidarisé par des moyens de fixation - un second organe susceptible d'etre introduit en bout d'un autre profilé, en y étant solidarisé par des moyens de fixation ; et, - un axe d'articulation associant l'un à l'autre les premier et second organes et disposé orthogonalement au plan formé par les deux profilés assemblés.To this end, the system for assembling hollow profiles for the production of bearing structures, of the type in which said system comprises connecting means capable of connecting two profiles and means for fixing said connecting means respectively on said profiles, is remarkable, according to the invention, in that said connecting means comprise - a first member capable of cooperating with the external profile of one of the profiles, by being joined to it by fixing means - a second member capable of being introduced at the end of another profile, by being joined to it by fixing means; and, - a hinge pin associating the first and second members with one another and disposed orthogonally to the plane formed by the two assembled profiles.

Ainsi, grâce audit axe d'articulation autour duquel peuvent pivoter les deux organes, on peut assembler les deux profilés selon l'angle souhaité.Thus, by virtue of said articulation axis around which the two members can pivot, the two sections can be assembled at the desired angle.

Généralement, les premier et second organes dudit système sont destinés à assembler des profilés creux présentant une section polygonale, comportant sur chacune de leurs faces longitudinales un profil en queue d'aronde contenant.Generally, the first and second members of said system are intended to assemble hollow profiles having a polygonal section, comprising on each of their longitudinal faces a dovetail profile containing.

Dans ce cas, ledit premier organe présente, de préférence, la forme d'une chape en U, dont les flancs latéraux sont percés de trous de passage coaxiaux et dont la base, destinée à venir au contact de l'une des faces longitudinales d'un profilé, est pourvue d'une languette médiane orthogonale aux trous de passage coaxiaux des flancs et faisant saillie de la base, ladite languette s t insérant entre les bords longitudinaux dudit profil correspondant en queue d'aronde.In this case, said first member preferably has the form of a U-shaped yoke, the lateral flanks of which are pierced with coaxial passage holes and the base of which, intended to come into contact with one of the longitudinal faces d 'a profile, is provided with a middle tongue orthogonal to the coaxial passage holes of the sides and projecting from the base, said tongue st inserting between the longitudinal edges of said corresponding profile dovetail.

Les moyens de fixation du premier organe comprennent alors une cale qui présente une section correspondante au profil en queue d'aronde en s'y engageant, et, au moins une vis traversant un trou de passage ménagé dans la base puis un trou taraudé ménagé dans la cale, pour venir au contact du fond dudit profil en queue d'aronde.The means for fixing the first member then comprise a wedge which has a section corresponding to the dovetail profile when engaging therein, and, at least one screw passing through a through hole made in the base and then a tapped hole made in the wedge, to come into contact with the bottom of said dovetail profile.

Quant audit second organe, il présente avantageusement une embase destinée à venir en appui contre l'une des faces transversales d'extrémité de l'autre profilé à assembler, ladite embase se prolongeant d'un côté, par une tige dont la section correspond à celle en creux dudit profilé, en s'engageant dans celui-ci, et, de l'autre côté, par au moins une patte pourvue d'un trou de passage orthogonal à la tige.As for said second member, it advantageously has a base intended to come into abutment against one of the transverse end faces of the other profile to be assembled, said base extending on one side, by a rod whose cross section corresponds to that in the hollow of said profile, by engaging therein, and, on the other side, by at least one tab provided with a passage hole orthogonal to the rod.

Les moyens de fixation dudit second organe comprennent, par exemple, au moins une vis ou analogue, traversant des orifices ménagés en correspondance dans le fond d'un desdits profils en queue-d'aronde et dans ladite tige.The means for fixing said second member comprise, for example, at least one screw or the like, passing through orifices formed in correspondence in the bottom of one of said dovetail profiles and in said rod.

Dans un mode préféré de réalisation, ledit axe d'articulation est avantageusement défini par un boulon s'engageant dans les trous de passage prévus en correspondance dans les flancs du premier organe et dans la patte du second organe, introduite entre les flancs du premier organe.In a preferred embodiment, said articulation axis is advantageously defined by a bolt engaging in the through holes provided in correspondence in the flanks of the first member and in the tab of the second member, introduced between the flanks of the first member .

Selon une autre caractéristique dudit système, les faces externes des flancs dudit premier organe et les faces externes de la patte dudit second organe comportent chacune des nervures agencées en forme de croix. Cet agencement accroit la rigidité desdits organes et offre un aspect esthétique certain.According to another characteristic of said system, the external faces of the sides of said first member and the external faces of the tab of said second member each have ribs arranged in the shape of a cross. This arrangement increases the rigidity of said members and offers a certain aesthetic appearance.

Dans un autre mode de réalisation, ledit premier organe est susceptible de coopérer avec un profilé creux à section circulaire, tandis que ledit second organe est destiné à etre introduit en bout d'un profilé creux à section polygonale, circulaire ou autre. In another embodiment, said first member is capable of cooperating with a hollow section with circular section, while said second member is intended to be inserted at the end of a hollow section with polygonal, circular or other section.

Dans ce cas, ledit premier organe peut comporter une partie circulaire évidée dans laquelle est susceptible de s'introduire ledit profilé circulaire, ladite partie circulaire se prolongeant par deux flancs latéraux espacés et parallèles, pourvus de trous de passage ménagés en correspondance et orthogonaux à l'axe de ladite partie circulaire.In this case, said first member may comprise a hollowed-out circular part into which said circular section may be introduced, said circular part being extended by two spaced and parallel lateral flanks, provided with through holes made in correspondence and orthogonal to the axis of said circular part.

Les figures du dessin annexé feront bien comprendre comment l'invention peut être réalisée. Sur ces figures, des références identiques désignent des éléments semblables.The figures of the appended drawing will make it clear how the invention can be implemented. In these figures, identical references designate similar elements.

Les figures 4A et 4E représentent, selon deux vues en plan perpendiculaires, un troisième organe destiné à être interposé entre les premier et second organes.Figures 4A and 4E show, in two perpendicular plan views, a third member intended to be interposed between the first and second members.

Les figures 5A,5B et 5C représentent, selon trois vues différentes, un autre mode de réalisation dudit premier organe destiné à coopérer avec un profilé creux à section circulaire.Figures 5A, 5B and 5C show, in three different views, another embodiment of said first member intended to cooperate with a hollow section with circular section.

La figure 9 montre une vue en plan d'un exemple de réalisation d'une structure portante à partir de profilés assemblés par les systèmes d'assemblage selon l'invention.FIG. 9 shows a plan view of an exemplary embodiment of a bearing structure from profiles assembled by the assembly systems according to the invention.

La figure 10A est une coupe d'un dispositif d'assemblage de profilés à section circulaire, et, les figures 10B et 10C sont respectivement en vue de dessus deux variantes de réalisation de l'une des pièces du dispositif d'assemblage de la figure îOA. FIG. 10A is a section of a device for assembling sections with a circular section, and, FIGS. 10B and 10C are respectively a top view of two alternative embodiments of one of the parts of the assembly device in FIG îOA.

En se référant à la figure 1, le système d'assemblage représenté 1, selon l'invention, est destiné à réunir deux profilés creux 2 et 3 ayant, dans cet exemple de réalisation, des sections identiques mais pouvant être de longueurs différentes, adaptées aux besoins.Referring to Figure 1, the assembly system shown 1, according to the invention, is intended to join two hollow sections 2 and 3 having, in this embodiment, identical sections but may be of different lengths, adapted needs to.

Le système d'assemblage 1 comprend un premier organe 4 susceptible de coopérer avec le profilé 2, un second organe 5 susceptible d'être introduit en bout du profilé 3, et, un axe d'articulation 6 destiné à réunir les deux organes 4 et 5 et disposé orthogonalement au plan formé par les deux profilés à assembler. Les organes 4 et 5, ainsi que l'axe 6, définissent les moyens de liaison du système d'assembla- ge 1.The assembly system 1 comprises a first member 4 capable of cooperating with the profile 2, a second member 5 capable of being introduced at the end of the profile 3, and, a hinge pin 6 intended to join the two members 4 and 5 and arranged orthogonally to the plane formed by the two sections to be assembled. The members 4 and 5, as well as the axis 6, define the connection means of the assembly system 1.

On voit sur la figure î que chaque profilé creux 2 et 3 présente une section transversale carrée. Aussi, sur les quatre faces longitudinales 2A et 3A, respectivement des profilés 2 et 3, sont ménagés des profils contenants en queue d'aronde, respectivement 7 et 8. Chaque profil en queue d'aronde est délimité par un fond, respectivement 7A et 8A, parallèle à la face longitudinale correspondante, et raccordé à cette face par deux ailes coudées, respectivement 7B et 8B, formant chacune un V concave.It can be seen in FIG. 1 that each hollow section 2 and 3 has a square cross section. Also, on the four longitudinal faces 2A and 3A, profiles 2 and 3 respectively, profiles are provided containing dovetail profiles, respectively 7 and 8. Each dovetail profile is delimited by a bottom, respectively 7A and 8A, parallel to the corresponding longitudinal face, and connected to this face by two bent wings, 7B and 8B respectively, each forming a concave V.

Sur la figure 1, le premier organe 4 se présente sous la forme d'une chape ou d'un étrier ayant une section en U.In Figure 1, the first member 4 is in the form of a yoke or a stirrup having a U-shaped section.

Les deux flancs latéraux 4A de l'organe sont percés de trous de passage coaxiaux 4B. Par ailleurs, la base 4C de l'organe 4, qui est destinée à venir en appui contre la face longitudinale correspondante 2A du profilé 2, est pourvue d'une languette médiane 4D faisant saillie de ladite base 4C. Les trous de passage dB des flancs 4A sont orthogonaux à la languette médiane 4D, cette dernière étant susceptible d'etre insérée entre les bords d'extrémité 7C des ailes coudées 7B du profil en queue d'aronde 7, .en réalisant de la sorte une liaison en translation.The two lateral sides 4A of the member are pierced with coaxial passage holes 4B. Furthermore, the base 4C of the member 4, which is intended to come into abutment against the corresponding longitudinal face 2A of the profile 2, is provided with a middle tab 4D projecting from said base 4C. The through holes dB of the flanks 4A are orthogonal to the middle tab 4D, the latter being capable of being inserted between the end edges 7C of the bent wings 7B of the dovetail profile 7,. Thus making a translational link.

Les moyens de fixation du premier organe 4 comprennent, par exemple, une cale 10 présentant une section analogue à celle du profilé en queue d'aronde 7. Sur la figure 1, la cale 10 est introduite dans la queue d'aronde 7 en étant positionnée à l'extrémité de la face longitudinale 2A du profilé 2, à proximité de la face transversale d'extrémité 2B. La cale comporte deux trous taraudés 10A avec lesquels viennent en correspondance des trous de passage 4E ménagés dans la base 4C de l'organe 4, en traversant la languette médiane 4D Ainsi, par l'intermédiaire de deux vis 10B, dont une est représentée sur la figure 1, on réalise l'immobilisation de l'organe 4 sur le profile 2.The means for fixing the first member 4 comprise, for example, a wedge 10 having a section similar to that of the dovetail profile 7. In FIG. 1, the wedge 10 is introduced into the dovetail 7 by being positioned at the end of the longitudinal face 2A of the profile 2, near the transverse end face 2B. The wedge has two threaded holes 10A with which there correspond passage holes 4E formed in the base 4C of the member 4, crossing the middle tab 4D Thus, by means of two screws 10B, one of which is shown on in FIG. 1, the member 4 is immobilized on the profile 2.

Quant au second organe 5, il comprend une embase 5A dont la section carrée est sensiblement analogue à celle formée par les quatre faces 3A à l'extrémité 3B du profilé.As for the second member 5, it comprises a base 5A whose square section is substantially similar to that formed by the four faces 3A at the end 3B of the profile.

D'un côté, l'embase 5A est prolongée d'une tige 5B dont la section de forme carrée correspond à celle du creux 3C du profilé 3, et, de l'autre côté, par une patte médiane 5C pourvue d'un trou de passage 5D perpendiculaire à la direction générale du second organe. Le second organe 5 est introduit par sa tige 5B dans le creux 3C du profilé 3 jusqu'à ce que l'embase 5A vienne en butée contre la face d'extrémité transversale 3B dudit profilé.On one side, the base 5A is extended by a rod 5B whose cross-section of square shape corresponds to that of the hollow 3C of the profile 3, and, on the other side, by a central tab 5C provided with a hole 5D passage perpendicular to the general direction of the second member. The second member 5 is introduced by its rod 5B into the hollow 3C of the profile 3 until the base 5A abuts against the transverse end face 3B of said profile.

Les moyens de fixation du second organe 5 peuvent, par exemple, comprendre deux vis 11, dont une est représentée, qui s'engagent dans des passages respectivement 3D et SE pratiqués en correspondance, dans le fond 3A d'un des profils en queue d'aronde du profilé 3 et dans la tige carrée 5B.The fastening means of the second member 5 can, for example, comprise two screws 11, one of which is shown, which engage in passages respectively 3D and SE practiced in correspondence, in the bottom 3A of one of the tail profiles d 'dovetail of the profile 3 and in the square rod 5B.

L'axe d'articulation 6 peut être défini par un boulon, dont la vis 6A s'engage dans -ies trous de passage 4B et 5D, respectivement des flancs latéraux A du premier organe 4 et de la patte médiané 5C du second organe. La patte médiane 5C s'insère parfaitement entre les flancs latéraux 4A. Un écrou 6B immobilise alors la liaison entre les deux organes. Grâce à cet axe 6, on peut donc agencer les deux profilés 2 et 3 selon l'angle souhaité. On remarque aussi que le système d'assemblage comprend un nombre réduit d'éléments.The articulation axis 6 can be defined by a bolt, the screw 6A of which engages in the through holes 4B and 5D, respectively of the lateral flanks A of the first member 4 and of the median tab 5C of the second member. The middle tab 5C fits perfectly between the lateral flanks 4A. A nut 6B then immobilizes the connection between the two members. Thanks to this axis 6, it is therefore possible to arrange the two sections 2 and 3 according to the desired angle. We also note that the assembly system includes a reduced number of elements.

Par ailleurs, on voit sur la figure 1 que les faces externes 4F des flancs latéraux 4A de l'organe 4, ainsi que les faces externes 5F de la patte médiane 5C de l'organe 5, comportent chacune des nervures, respectivement 4G et 5G, agencées en forme de croix. Ces nervures améliorent la rigidité desdits organes, réalisés par exemple en aluminium, et apportent de plus un aspect esthétique attrayant. Furthermore, it can be seen in FIG. 1 that the external faces 4F of the lateral flanks 4A of the member 4, as well as the external faces 5F of the middle tab 5C of the member 5, each have ribs, respectively 4G and 5G , arranged in the shape of a cross. These ribs improve the rigidity of said members, made for example of aluminum, and moreover provide an attractive aesthetic appearance.

Les figures 2 et 3 montrent le système d'assemblage 1 monté, associant les deux profilés 2 et 3 l'un à l'autre en formant entre eux, dans cet exemple de réalisation, un angle de 450
Le montage et la fixation des organes sur lesdits profilés s'effectuent aisément et rapidement, sans difficultés.Figures 2 and 3 show the assembly system 1 mounted, associating the two sections 2 and 3 to each other forming between them, in this embodiment, an angle of 450
The mounting and fixing of the members on said sections is carried out easily and quickly, without difficulties.

On remarque sur la figure 3 que la tête de la vis 6A et l'écrou 6B sont noyées dans les flancs latéraux 4A de l'organe 4.Note in FIG. 3 that the head of the screw 6A and the nut 6B are embedded in the lateral flanks 4A of the member 4.

Bien évidement, on peut agencer sur les autres faces 2A et 3A des profilés des systèmes d'assemblage permettant de relier plusieurs profilés à un même profilé. Pour cela, on a représenté sur la figure 2 en traits mixtes un second organe 5 qui est agencé en bout du profilé 2 et avec lequel est destiné à coopérer un premier organe immobilisé sur un autre profilé.Obviously, one can arrange on the other faces 2A and 3A of the profiles of the assembly systems making it possible to connect several profiles to the same profile. For this, there is shown in Figure 2 in broken lines a second member 5 which is arranged at the end of the profile 2 and with which is intended to cooperate a first member immobilized on another profile.

Les figures 4A et 4B montrent un troisième organe 14 qui autorise la liaison entre les premier et second organes. Ce troisième organe 14 comporte une chape 14A en forme de U, identique à celle dudit premier organe et pourvue de deux flancs latéraux 14B percés de trous de passage 14C en correspondance. Une patte médiane 14D, identique à celle du second organe, prolonge la base 14E de la chape et est munie d'un trou de passage 14F orthogonal aux trous 14C.FIGS. 4A and 4B show a third member 14 which authorizes the connection between the first and second members. This third member 14 comprises a yoke 14A in the shape of a U, identical to that of said first member and provided with two lateral flanks 14B pierced with through holes 14C in correspondence. A central tab 14D, identical to that of the second member, extends the base 14E of the yoke and is provided with a through hole 14F orthogonal to the holes 14C.

Cette troisième pièce 14 fait office de joint universel.This third part 14 acts as a universal joint.

Dans l'exemple de réalisation illustré sur les figures 5A,5B et 5C, le premier organe 15 est destiné à coopérer avec un profilé'de section circulaire 16. Pour cela, le premier organe 15 comporte une partie circulaire 15A évidée dans laquelle est introduit le profilé 16. La partie circulaire 15A se prolonge par deux flancs latéraux 15B espacés et parallèles, pourvus de trous de passage 15C ménagés en correspondance et orthogonaux à l'axe géométrique de la partie circulaire 15A. Par ailleurs, il est également prévu dans l'organe 15 un trou taraudé 15D débouchant dans la partie circulaire et entre les deux flancs latéraux.Ce trou 15D, orthogonal à l'axe de la partie circulaire et aux trous de passage 15C, reçoit une vis, non représentée, qui vient au contact du profilé 16 en immobilisant alors l'organe 15 au profilé.In the exemplary embodiment illustrated in FIGS. 5A, 5B and 5C, the first member 15 is intended to cooperate with a profiled section of circular section 16. For this, the first member 15 comprises a circular part 15A hollowed out into which is introduced the profile 16. The circular part 15A is extended by two lateral flanks 15B spaced and parallel, provided with through holes 15C formed in correspondence and orthogonal to the geometric axis of the circular part 15A. Furthermore, there is also provided in the member 15 a threaded hole 15D opening into the circular part and between the two lateral flanks. This hole 15D, orthogonal to the axis of the circular part and to the through holes 15C, receives a screw, not shown, which comes into contact with the profile 16 while immobilizing the member 15 to the profile.

Entre les flancs latéraux 15B du premier organe 15 est destinée à etre introduite la patte médiane d'un second organe, un axe d'articulation assemblant les flancs 15B et la patte médiane.Between the lateral flanks 15B of the first member 15 is intended to be introduced the middle leg of a second member, a hinge pin joining the sides 15B and the middle leg.

Sur les figures 6A et 6B, le second organe 17 représenté est pratiquement identique au second organe 5 décrit en regard des figures 1 à 3. Il ne comporte pas de nervures sur les faces latérales de sa patte médiane 17A, tandis que sa tige 17B est pourvue d'une empreinte conique 17C. Aussi, la fixation de l'organe 17 introduit en bout d'un profilé s'effectue par l'engagement de l'extrémité conique d'une vis, non représentée, dans l'empreinte 17C. Par ailleurs, dans la patte médiane 17A est ménagé un trou de passage 17D dans lequel est susceptible d'être introduit l'axe d'articulation 6.In FIGS. 6A and 6B, the second member 17 shown is practically identical to the second member 5 described with reference to FIGS. 1 to 3. It has no ribs on the lateral faces of its median tab 17A, while its rod 17B is provided with a conical imprint 17C. Also, the attachment of the member 17 introduced at the end of a profile is effected by the engagement of the conical end of a screw, not shown, in the cavity 17C. Furthermore, in the middle tab 17A is provided a passage hole 17D into which the hinge pin 6 can be introduced.

Le second organe î8 représenté sur les figures 7A et 7B comprend, quant à lui, une embase 18A de laquelle s'étend, d'un côté, une tige 18B, susceptible de s'engager dans le creux d'un profilé à assembler, et, de l'autre côté, par deux flancs latéraux 18C pouvus de trous de passage 18D ménagés en correspondance. Une empreinte conique 18E, analogue à celle 17C de l'organe 17, est, par exemple, prévue dans la tige. Dans cette réalisation, pour associer les premier et second organes par l'axe d'articulation et réunir selon l'angle souhaité les deux profilés, le premier organe, non représenté, présente alors une patte médiane au lieu des deux flancs latéraux usuels, laquelle patte s'insère entre les deux flancs 18C du second organe 18.The second member 18 shown in FIGS. 7A and 7B comprises, for its part, a base 18A from which extends, on one side, a rod 18B, capable of engaging in the hollow of a profile to be assembled, and, on the other side, by two lateral flanks 18C capable of through holes 18D formed in correspondence. A conical imprint 18E, similar to that 17C of the member 17, is, for example, provided in the rod. In this embodiment, to associate the first and second members by the articulation axis and join the two sections at the desired angle, the first member, not shown, then has a central tab instead of the two usual lateral flanks, which tab fits between the two sides 18C of the second member 18.

La tige 5B, 17B et 18B, respectivement des seconds organes 5,17 et 18, peut présenter une section circulaire, carrée, ou autre correspondant à celle du creux dudit profilé utilisé. Lorsqu'une face d'extrémité transversale d'un profilé ne reçoit pas de second organe, on peut avantageusement l'obturer par un bouchon 19, tel que représenté sur les figures 8A et 8B.The rod 5B, 17B and 18B, respectively of the second members 5, 17 and 18, may have a circular, square, or other cross section corresponding to that of the hollow of said profile used. When a transverse end face of a profile does not receive a second member, it can advantageously be closed off with a plug 19, as shown in FIGS. 8A and 8B.

On a illustré sur la figure 9 un exemple de réalisation d'une structure portante 20 obtenue à partir de profilés 21 (analogues aux profilés 2 et 3 décrits préalablement) reliés entre eux grace aux systèmes d'assemblage 1 de l'invention, qui permettent d'assembler les profilés selon des angles quelconques. Des troisième organes 14 sont également illustrés et permettent, chacun, de relier des premier et second organes 4 et 5.Illustrated in FIG. 9 is an exemplary embodiment of a supporting structure 20 obtained from profiles 21 (analogous to profiles 2 and 3 described previously) connected together by means of the assembly systems 1 of the invention, which allow to assemble the profiles at any angles. Third members 14 are also illustrated and allow, each, to connect first and second members 4 and 5.

Par ailleurs, on a représenté un système d'assemblage 1A permettant de réunir perpendiculairement un profilé à section polygonale 21 à un profilé circulaire 22, qui correspond à l'un des profilés formant un garde-fou 23 monté sur la structure 20.Furthermore, an assembly system 1A has been shown making it possible to join perpendicularly a profile with polygonal section 21 to a circular profile 22, which corresponds to one of the profiles forming a railing 23 mounted on the structure 20.

Aussi, pour réunir par exemple les profilés circulaires 22, on peut utiliser un dispositif d'assemblage 24, tel que celui illustré sur les figures 10A et 10E. Also, to join for example the circular profiles 22, one can use an assembly device 24, such as that illustrated in Figures 10A and 10E.

Ce dispositif 2'4 comprend deux demi-coquilles identiques 24A assemblées l'une à l'autre par des vis 25, traversant des trous de passage 24B ménagés en correspondance dans ces demi-coquilles. Chacune d'elles présente à sa partie médiane 24C un profil circulaire 24D destiné à recevoir un profilé circulaire et à chacune de ses parties d'extrémité 24E un profil circulaire 24F, perpendiculaire au profil 24D.This device 2'4 comprises two identical half-shells 24A assembled to one another by screws 25, passing through through holes 24B formed in correspondence in these half-shells. Each of them has at its central part 24C a circular profile 24D intended to receive a circular profile and at each of its end parts 24E a circular profile 24F, perpendicular to the profile 24D.

Sur la figure 10C est représentée une variante de réalisation de la demi-coquille 24A qui ne comporte qu'une partie d'extrémité à profil circulaire. In Figure 10C is shown an alternative embodiment of the half-shell 24A which has only one end portion with a circular profile.
