Description

SYSTEME D'ASSEMBLAGE POUR ELEMENTS LONGIFORMES ASSEMBLY SYSTEM FOR LONGIFORM ELEMENTS
La présente invention concerne un système d'assemblage pour éléments longiformes. Ce système est notamment destiné à être utilisé pour l'assemblage d'éléments profilés constituant l'ossature d'un stand d'exposition, en particulier des traverses et des poteaux. Il peut également être utilisé dans le domaine de l'ameublement, pour permettre l'assemblage simple et rapide de meubles.The present invention relates to an assembly system for elongated elements. This system is in particular intended to be used for the assembly of profiled elements constituting the framework of an exhibition stand, in particular sleepers and posts. It can also be used in the field of furniture, to allow simple and rapid assembly of furniture.
Il est connu, par le document DE 31 31 537, d'assembler un premier profilé, notamment une traverse, à un deuxième profilé, notamment un poteau, au moyen d'une pièce d'assemblage engagée dans ledit premier profilé ; cette pièce d'assemblage est formée par deux éléments montés pivotants l'un par rapport à l'autre au niveau de l'une de leurs extrémités, ces éléments présentant des parties en forme de mâchoires à leurs autres extrémités ; l'un de ces deux éléments comprend un trou taraudé tandis que l'autre élément comprend un trou non taraudé, et une vis est engagée dans ces trous, la tête de la vis étant située du côté de l'élément qui comprend le trou non taraudé ; ledit deuxième profilé comprend au moins une nervure longitudinale, et lesdites parties en forme de mâchoires sont conformées pour, lorsque la vis est serrée, venir en prise avec cette nervure, en la serrant entre elles, afin de réaliser l'assemblage des deux profilés.It is known, from document DE 31 31 537, to assemble a first profile, in particular a cross member, to a second profile, in particular a post, by means of an assembly part engaged in said first profile; this assembly part is formed by two elements mounted to pivot relative to one another at one of their ends, these elements having jaw-shaped parts at their other ends; one of these two elements comprises a tapped hole while the other element comprises a non-tapped hole, and a screw is engaged in these holes, the head of the screw being located on the side of the element which comprises the non-tapped hole tapped; said second profile comprises at least one longitudinal rib, and said jaw-shaped parts are shaped so that, when the screw is tight, come into engagement with this rib, by tightening it together, in order to assemble the two profiles.
Ce système d'assemblage a pour inconvénient d'être difficile à manipuler. En effet, ladite pièce d'assemblage doit être translatée au moyen de la vis, dont la tête dépasse sur l'extérieur de la traverse, pour amener lesdites parties en forme de mâchoires autour de la nervure ; selon le degré d'écartement desdits éléments constituant cette pièce, il peut être particulièrement difficile d'engager lesdites parties en forme de mâchoire autour de la nervure, et l'on ne peut être parfaitement sûr que cet engagement est bien total ; les installateurs doivent "chercher" la position d'assemblage, ce qui, compte tenu du nombre de traverses et poteaux pouvant être assemblés pour constituer un ou plusieurs stands d'exposition, est extrêmement fastidieux et peut nécessiter beaucoup de temps.This assembly system has the disadvantage of being difficult to handle. Indeed, said assembly part must be translated by means of the screw, the head of which protrudes from the outside of the cross member, in order to bring said jaw-shaped parts around the rib; depending on the degree of spacing of said elements constituting this part, it may be particularly difficult to engage said jaw-shaped parts around the rib, and one cannot be perfectly sure that this engagement is indeed total; installers must "search" for the assembly position, which, taking into account the number of crosspieces and posts that can be assembled to constitute one or more exhibition stands, is extremely tedious and can require a great deal of time.
De plus, une usure desdites parties en forme de mâchoire et/ou de la nervure est à craindre au fur et à mesure des montages et démontages des traverses, amoindrissant la fiabilité de l'assemblage. La présente invention vise à remédier à ces inconvénients essentiels, sans amoindrissement de la résistance de l'assemblage obtenu et sans complexifier à outrance la structure du système d'assemblage.In addition, wear of said jaw-shaped parts and / or of the rib is to be feared as the crossmembers are assembled and disassembled, reducing the reliability of the assembly. The present invention aims to remedy these essential drawbacks, without reducing the strength of the assembly obtained and without excessively complexifying the structure of the assembly system.
Ce système d'assemblage est du genre de celui divulgué par le brevet DE 31 31 537, le préambule de la revendication 1 étant basé sur l'enseignement de ce document.This assembly system is of the type disclosed by patent DE 31 31 537, the preamble of claim 1 being based on the teaching of this document.
Selon l'invention,According to the invention,
- la pièce d'assemblage comprend un moyen élastique permettant de maintenir normalement ses deux éléments constitutifs en position mutuellement écartée, de telle sorte que ces éléments soient au contact des parois dudit premier profilé ;- The assembly part comprises an elastic means making it possible to normally maintain its two constituent elements in a mutually separated position, so that these elements are in contact with the walls of said first profile;
- chacun de ces éléments comprend un bossage faisant saillie de sa face extérieure, les hauteurs des deux bossages étant telles que, lorsque ces bossages sont au contact des parois correspondantes dudit premier profilé, ils limitent l'écartement des parties en forme de mâchoires de telle sorte que cet écartement corresponde à la largeur de la nervure ; et- Each of these elements comprises a boss projecting from its outer face, the heights of the two bosses being such that, when these bosses are in contact with the corresponding walls of said first profile, they limit the spacing of the jaw-shaped parts of such so that this spacing corresponds to the width of the rib; and
- la tête de la vis est engagée au travers d'un trou aménagé dans ledit premier profilé et vient, au cours de son serrage, porter contre l'élément qui comprend le trou non taraudé, de manière à rapprocher lesdits éléments l'un de l'autre.- The head of the screw is engaged through a hole in said first profile and comes, during its tightening, bear against the element which includes the non-tapped hole, so as to bring said elements one of the other.
Lors du desserrage de la vis, les éléments constituant ladite pièce s'écartent l'un de l'autre jusqu'à ce que leurs bossages viennent rencontrer la paroi dudit premier profilé ; ces éléments se trouvent alors parfaitement centrés par rapport à ce profilé et ont un écartement juste suffisant pour permettre le dégagement desdites parties en forme de mâchoire d'autour de la nervure. Le démontage d'une traverse est ainsi particulièrement facile et rapide à réaliser.During the loosening of the screw, the elements constituting said part deviate from each other until their bosses come to meet the wall of said first profile; these elements are then perfectly centered relative to this profile and have a spacing just sufficient to allow the release of said jaw-shaped parts around the rib. The disassembly of a cross member is thus particularly easy and quick to perform.
Le montage d'une traverse est tout aussi facile à réaliser puisque lesdits éléments sont centrés et calés par rapport à cette traverse, et qu'un nombre juste suffisant de tours de vis est rendu nécessaire pour amener lesdites parties en forme de mâchoire en prise avec la nervure.The mounting of a crosspiece is just as easy to perform since said elements are centered and wedged with respect to this crosspiece, and that a just sufficient number of turns of the screw is made necessary to bring said jaw-shaped parts into engagement with the rib.
Dans tous les cas, aucune usure ne se produit, et toute assurance est acquise quant à la fiabilité de l'assemblage obtenu.In all cases, no wear occurs, and any assurance is acquired as to the reliability of the assembly obtained.
De préférence, ledit moyen élastique est constitué par un cylindre en matière compressible, tel que du caoutchouc. La nervure et les parties en forme de mâchoires peuvent être conformées de manière telle que les extrémités des parties en forme de mâchoires portent contre la paroi dudit deuxième profilé comportant cette nervure lorsque ces mêmes parties en forme de mâchoires sont en prise avec ladite nervure.Preferably, said elastic means consists of a cylinder of compressible material, such as rubber. The rib and the jaw-shaped parts can be shaped so that the ends of the jaw-shaped parts bear against the wall of said second section having this rib when these same jaw-shaped parts are engaged with said rib.
Un calage en rotation du premier profilé par rapport au deuxième profilé est ainsi obtenu.A setting in rotation of the first profile relative to the second profile is thus obtained.
Le système d'assemblage peut comprendre deux ailes faisant saillie de part et d'autre de chaque nervure précitée, pourvues de retours à leurs extrémités libres, lesdits retours, ailes, nervures, pièce d'assemblage et premier profilé étant conformés de telle sorte que l'extrémité dudit premier profilé vienne en appui contre ces retours lorsque lesdites parties en forme de mâchoires sont en prise avec la nervure.The assembly system may comprise two wings projecting on either side of each aforementioned rib, provided with returns at their free ends, said returns, wings, ribs, assembly piece and first profile being shaped so that the end of said first section bears against these returns when said jaw-shaped parts are engaged with the rib.
Un parfait calage anti-rotation du premier profilé par rapport au deuxième profilé est obtenu.A perfect anti-rotation setting of the first profile relative to the second profile is obtained.
Selon une forme de réalisation préférée de l'invention dans ce cas, la nervure comprend un bourrelet de forme arrondie au niveau de son extrémité libre et lesdites parties en forme de mâchoires présentent des cavités arrondies correspondantes. L'engagement des parties en forme de mâchoires autour de ce bourrelet permet d'assurer la venue en prise de ces parties et du bourrelet.According to a preferred embodiment of the invention in this case, the rib comprises a bead of rounded shape at its free end and said jaw-shaped parts have corresponding rounded cavities. The engagement of the jaw-shaped parts around this bead ensures that these parts and the bead come into engagement.
Le pivotement des éléments l'un par rapport à l'autre peut être réalisé par des parties complémentaires engagées de manière pivotante l'une dans l'autre. Selon une forme de réalisation préférée de l'invention, chaque élément comprend un evidement hémi-cylindrique, ces deux évidements venant en regard l'un de l'autre en position d'assemblage de ces éléments et recevant une vis formant l'axe d'articulation des éléments, un bossage arrondi étant prévu sur la face extérieure de chacun des éléments pour permettre de maintenir lesdits évidements engagés autour de ladite vis.The pivoting of the elements relative to each other can be achieved by complementary parts pivotally engaged in one another. According to a preferred embodiment of the invention, each element comprises a semi-cylindrical recess, these two recesses coming opposite one another in the assembly position of these elements and receiving a screw forming the axis d 'articulation of the elements, a rounded boss being provided on the outer face of each of the elements to allow to maintain said recesses engaged around said screw.
La vis traverse avantageusement les parois de ce profilé, de sorte que la pièce est facilement montée dans ce profilé et que sa position longitudinale par rapport à ce dernier est précisément déterminée par la position de cette vis. Pour sa bonne compréhension, l'invention est à nouveau décrite ci-dessous en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme de réalisation préférée du système d'assemblage qu'elle concerne.The screw advantageously crosses the walls of this profile, so that the part is easily mounted in this profile and that its longitudinal position relative to the latter is precisely determined by the position of this screw. For its proper understanding, the invention is again described below with reference to the appended schematic drawing representing, by way of non-limiting example, a preferred embodiment of the assembly system it relates to.
La figure 1 est une vue en perspective de diverses parties que comprend ce système ; la figure 2 est une vue de ce système, en coupe longitudinale, avant assemblage ; la figure 3 en est une vue similaire à la figure 2, après assemblage, et la figure 4 en est une vue en coupe dans un plan perpendiculaire au plan de coupe selon les figures 2 et 3.Figure 1 is a perspective view of various parts included in this system; Figure 2 is a view of this system, in longitudinal section, before assembly; FIG. 3 is a view similar to FIG. 2, after assembly, and FIG. 4 is a sectional view in a plane perpendicular to the cutting plane according to FIGS. 2 and 3.
Les figures représentent, sous différents angles, un système d'assemblage pour éléments longiformes, notamment destiné à être utilisé pour l'assemblage de traverses 2 et de poteaux de soutien 3 constituant l'ossature d'un stand d'exposition. Les traverses 2 sont profilées et creuses intérieurement. Les poteaux 3 sont également profilés et comprennent des rainures longitudinales 4 délimitées latéralement par des ailes 5 en saillie, ces ailes 5 comprenant des retours 6 à leurs extrémités libres, dirigés vers l'intérieur desdites rainures 4. Une traverse 2 peut être assemblée à un poteau 3 au moyen d'une pièce d'assemblage 10 formée par deux éléments 1 1 , 12 placés côte à côte, cette pièce 10 étant engagée à l'intérieur de la traverse 2 et faisant partiellement saillie de celle-ci, pour pouvoir venir en prise avec une nervure 13 correspondante que comprend chaque poteau 3 dans chaque rainure 4. Les éléments 1 1 , 12 présentent des parties 1 1a, 12a en forme de mâchoires à leurs extrémités faisant saillie de la traverse 2, qui comprennent, au niveau des faces internes des éléments 1 1 , 12, des cavités arrondies 15. Ces cavités 15 sont propres à être engagées sur ladite nervure 13, qui présente au niveau de son extrémité libre un bourrelet 16 de forme correspondante.The figures represent, from different angles, an assembly system for elongated elements, in particular intended to be used for the assembly of crosspieces 2 and support posts 3 constituting the framework of an exhibition stand. The cross members 2 are internally profiled and hollow. The posts 3 are also profiled and include longitudinal grooves 4 delimited laterally by projecting wings 5, these wings 5 comprising returns 6 at their free ends, directed towards the inside of said grooves 4. A cross member 2 can be assembled to a post 3 by means of an assembly part 10 formed by two elements 11, 12 placed side by side, this part 10 being engaged inside the cross member 2 and partially projecting therefrom, in order to be able to come engaged with a corresponding rib 13 that each post 3 comprises in each groove 4. The elements 1 1, 12 have parts 1 1a, 12a in the form of jaws at their ends projecting from the cross member 2, which comprise, at the level of the internal faces of the elements 1 1, 12, rounded cavities 15. These cavities 15 are suitable for being engaged on said rib 13, which has at its free end a bead 16 of corresponding shape.
Chaque élément 1 1 , 12 comprend un evidement hémicylindrique, au niveau de son extrémité opposée à la partie 1 1a, 12a et dans sa face tournée vers l'autre élément. Ces deux évidements viennent en regard l'un de l'autre en position d'assemblage de ces éléments et reçoivent une vis 20 formant l'axe d'articulation des éléments. Un bossage arrondi 21 est prévu sur la face extérieure de chacun des éléments 1 1 , 12 pour permettre de maintenir lesdits évidements engagés autour de ladite vis 20 lorsque la pièce 10 est engagée dans la traverse 2.Each element 1 1, 12 comprises a semi-cylindrical recess, at its end opposite to the part 1 1a, 12a and in its face facing the other element. These two recesses come opposite one another in the assembly position of these elements and receive a screw 20 forming the articulation axis of the elements. A rounded boss 21 is provided on the outer face of each of the elements 1 1, 12 to keep said recesses engaged around said screw 20 when the part 10 is engaged in the crosspiece 2.
Comme le montre la figure 4, la vis 20 est engagée dans des trous aménagés dans la traverse 2 et permet de déterminer précisément la position de la pièce 10 par rapport à l'extrémité de cette traverse 2.As shown in FIG. 4, the screw 20 is engaged in holes arranged in the cross-member 2 and makes it possible to precisely determine the position of the part 10 relative to the end of this cross-member 2.
L'un des deux éléments 1 1 comprend un trou non taraudé tandis que l'autre élément comprend un trou taraudé 22. Ces deux trous reçoivent une vis 25 dont la tête est située du côté de l'élément 1 1 comprenant le trou non taraudé, cette tête venant en appui contre cet élément lors du serrage de la vis 25, afin de permettre le rapprochement des éléments 1 1 , 12.One of the two elements 1 1 comprises a non-tapped hole while the other element comprises a tapped hole 22. These two holes receive a screw 25 whose head is located on the side of the element 1 1 comprising the non-tapped hole , this head coming to bear against this element when the screw 25 is tightened, in order to allow the elements 1 1, 12 to be brought together.
En outre, chacun des éléments 1 1 , 12 comprend un bossage 30 faisant saillie de sa face extérieure. Il apparaît que les hauteurs des deux bossages sont telles que, lorsque ces bossages 30 sont au contact des parois correspondantes de la traverse 2, ils limitent l'écartement des parties 1 1 a, 12a de telle sorte que cet écartement corresponde à la largeur de l'ouverture de chaque rainure 4.In addition, each of the elements 1 1, 12 comprises a boss 30 projecting from its outer face. It appears that the heights of the two bosses are such that, when these bosses 30 are in contact with the corresponding walls of the crossmember 2, they limit the spacing of the parts 1 1 a, 12a so that this spacing corresponds to the width of the opening of each groove 4.
Un cylindre 35 en matière compressible, tel que du caoutchouc, est placé entre les éléments 1 1 , 12. Il permet de maintenir normalement ces éléments en position mutuellement écartée, de telle sorte qu'ils soient au contact des parois de la traverse 2.A cylinder 35 of compressible material, such as rubber, is placed between the elements 11, 12. It allows these elements to be kept normally in a mutually separated position, so that they are in contact with the walls of the crosspiece 2.
Comme le montrent les figures, les retours 6, les ailes 5, chaque nervure 13, la pièce d'assemblage 10 et chaque traverse 2 sont conformés de telle sorte que l'extrémité de la traverse 2 vienne en appui contre ces retours 6 lorsque lesdites parties 1 1a, 12a en forme de mâchoires sont en prise avec la nervure 13 correspondante ; la nervure 13 et ces mêmes parties 1 1 a, 12a sont quant à elles conformées de manière telle que les extrémités de ces parties 1 1 a, 12a portent contre la paroi 40 du poteau 3 comportant cette nervure 13 lorsque ces mêmes parties 1 1 a, 12a sont en prise avec ladite nervure 13. Un parfait calage anti-rotation de la traverse 2 par rapport au poteau 3 est ainsi obtenu.As shown in the figures, the returns 6, the wings 5, each rib 13, the connecting piece 10 and each cross 2 are shaped so that the end of the cross 2 comes to bear against these returns 6 when said parts 1 1a, 12a in the form of jaws are engaged with the corresponding rib 13; the rib 13 and these same parts 1 1 a, 12a are for their part shaped such that the ends of these parts 1 1 a, 12a bear against the wall 40 of the post 3 comprising this rib 13 when these same parts 1 1 a , 12a are engaged with said rib 13. A perfect anti-rotation setting of the cross member 2 relative to the post 3 is thus obtained.
L'invention fournit un système d'assemblage permettant de remédier aux inconvénients des systèmes homologues de la technique antérieure en ce sens que le serrage ou le desserrage excessif de la vis 25 n'a aucun effet de déformation sur les profilés 2, 3 à assembler, la pièce d'assemblage 10 selon l'invention fonctionnant par serrage des éléments 11, 12 sur une nervure 13, donc de manière inverse des pièces homologues existantes. En outre, l'écartement des éléments 11, 12 est optimal, ce qui permet le guidage des parties 11a, 12a dans chaque rainure 4 et limite le nombre de tours de vis 25 à effectuer pour amener ces éléments 11, 12 en position de serrage. The invention provides an assembly system which makes it possible to remedy the drawbacks of homologous systems of the prior art in the sense that excessive tightening or loosening of the screw 25 has no deformation effect on the sections 2, 3 to be assembled. , the assembly piece 10 according to the invention operating by clamping the elements 11, 12 on a rib 13, therefore in reverse of existing homologous parts.
