Description

Dispositif d'assemblage multidirectionnel d'ossature Iégére.  Multidirectional Iégére framework assembly device.

La présente invention concerne la réalisation d'ossatures et de constructions métalliques légères pouvant être utilisées pour des applications multiples, fixes ou temporaires, telles que les petits abris, les petites charpentes métalliques, les stands, les plafonds décoratifs, les garages à bicyclettes, les supports d'enseigne, et tous ensembles d'équipement légers divers. The present invention relates to the production of light metal structures and constructions that can be used for multiple applications, fixed or temporary, such as small shelters, small metal frames, stands, decorative ceilings, bicycle garages, sign holders, and all sets of various light equipment.

Elle a pour objectif de créer un système d'assemblsge d'ossature esthétique, de faible encombrement, montable et démontable facilement, offrant un grand nombres d'utilisations possibles par son aspect multidirectionnel, et de grande sécurité par le fait qu'il ne comporte aucune soudure. Its objective is to create a system of aesthetic framework assemblies, compact, easy to assemble and disassemble, offering a large number of possible uses by its multidirectional aspect, and great security by the fact that it does not include no welding.

I1 est connu de réaliser des ossatures et constructions métalliques légères par assemblage de tubes ou profilés à l'aide de colliers, raccords ou dispositifs équivalents. On sait aussi résoudre le problème des décalages entre les plans d'assemblage lorsqu'on utilise des raccords simples ou des colliers, par un système multidirectionnel en queue d'aronde (Brevet européen 0008555 du demandeur). Toutefois ce dispositif présente des difficultés d'assemblage en ce que chaque barre de structure doit pénétrer dans la pièce d'assemblage par un mouvement longitudinal qui provoque des torsions de l'ensemble de la structure. D'autre part, la pièce d'assemblage est serrée par un boulon extérieur sensible aux oxydations. It is known to produce light metal structures and constructions by assembling tubes or profiles using collars, fittings or equivalent devices. We also know how to solve the problem of offsets between the assembly planes when using simple fittings or collars, by a multidirectional dovetail system (European patent 0008555 of the applicant). However, this device presents assembly difficulties in that each structural bar must enter the assembly part by a longitudinal movement which causes twists of the entire structure. On the other hand, the assembly part is tightened by an external bolt sensitive to oxidation.

La présente invention a pour objet un nouveau dispositif d'assemblage multidirectionnel d'ossature métallique légère comportant des nceuds d'assemblage et des barres de structure, caractérisé en ce que le nceud d'assemblage est une sphère percée radialement de trous taraudés et en ce que le dispositif est constitué d'une aiguille cylindrique d'accrochage, munie ô une extrémité d'une tige filetée coopérant avec les trous taraudés de la sphère pour solidariser l'aiguille et la sphère, d'un manchon mobile le long et autour de l'siguille, et d'un raccord de fixation ô vis coopérant d'une part avec le manchon, d'autre part avec la barre de structure pour assurer une liaison rigide entre la barre et l'aiguille. The subject of the present invention is a new multidirectional assembly device for a light metal frame comprising assembly nodes and structural bars, characterized in that the assembly node is a sphere radially pierced with tapped holes and in that that the device consists of a cylindrical hooking needle, provided at one end with a threaded rod cooperating with the threaded holes of the sphere to secure the needle and the sphere, with a movable sleeve along and around the needle, and a fixing connector ô screw cooperating on the one hand with the sleeve, on the other hand with the structural bar to ensure a rigid connection between the bar and the needle.

A titre d'exemple non limitatif, et pour faciliter la compréhension de l'invention, on a representé aux dessins annexés:
Figure 1, une vue en coupe transversale d'un exemple de réalisation de l'invention;
Figure 2, une vue en coupe transversale d'une variante de l'aiguille d'accrochage de dispositif selon l'invention.By way of nonlimiting example, and in order to facilitate understanding of the invention, the accompanying drawings show:
Figure 1, a cross-sectional view of an exemplary embodiment of the invention;
Figure 2, a cross-sectional view of a variant of the device attachment needle according to the invention.

En se reportant a la figure 1, on voit que le dispositif comporte une sphère 1, percée radialement de trous taraudés 2. La sphère représentée est pleine, mais elle peut être creuse ; elle comporte un grand nombre de trous. Referring to Figure 1, we see that the device comprises a sphere 1, pierced radially with tapped holes 2. The sphere shown is solid, but it may be hollow; it has a large number of holes.

Une pièce cylindrique de section circulaire en forme d'aiguille 3 comporte ô son extrémité une tige filetée 4 qui pénètre dans un trou taraudé 2 de la sphère. L'aiguille 3 est évidée en son centre, et forme un tube 31 taraudé du coté de son extrémité en contact avec la sphère. Une vis 32 du type sans tête d pans creux est placée dans ce filetage et assure la liaison avec la sphère. A cylindrical piece of circular section in the shape of a needle 3 has at its end a threaded rod 4 which penetrates into a tapped hole 2 of the sphere. The needle 3 is hollowed out at its center, and forms a tube 31 tapped on the side of its end in contact with the sphere. A screw 32 of the headless type of hexagon socket is placed in this thread and provides the connection with the sphere.

Selon une variante de réalisation illustrée figure 2, l'aiguille peut être pleine présentant à son extrémité une tige filetée. According to an alternative embodiment illustrated in FIG. 2, the needle may be solid, having at its end a threaded rod.

L'aiguille 3 comporte ô l'extrémité opposée ô la sphère un épaulement circulaire extérieur 5. The needle 3 has at the opposite end at the sphere an outer circular shoulder 5.

Un manchon 6 de forme cylindrique présente intérieurement un tube en deux parties séparées par un épaulement 7 ; du côté de la sphère le diamètre intérieur 8 du tube est légèrement supérieur au diamètre extérieur 9 de l'aiguille pour permettre au manchon d'être mobile sur l'aiguille. Du côté opposé d la sphère le diamètre intérieur 10 du tube est légèrement supérieur au diamètre 11 de l'épaulement 5 de l'aiguille pour permettre audit épaulement 5 de pénétrer dans le manchon et de s'appuyer sur l'épaulement 7 dudit manchon. A sleeve 6 of cylindrical shape has internally a tube in two parts separated by a shoulder 7; on the side of the sphere the inside diameter 8 of the tube is slightly greater than the outside diameter 9 of the needle to allow the sleeve to be movable on the needle. On the opposite side of the sphere, the internal diameter 10 of the tube is slightly greater than the diameter 11 of the shoulder 5 of the needle to allow said shoulder 5 to penetrate into the sleeve and to rest on the shoulder 7 of said sleeve.

En outre, le tube du manchon de grand diamètre Intérieur 10 est taraudé intérieurement 12. In addition, the tube of the large internal diameter sleeve 10 is internally threaded 12.

La longueur du manchon est légèrement inférieure ô celle de l'aiguille de sorte que l'aiguille étant fixée sur la sphère, lorsque le manchon est placé contre la sphère par glissement le long de l'oiguille, l'extrémité 20 de l'épaulement de l'aiguille se trouve dégagée du manchon. The length of the sleeve is slightly less than that of the needle so that the needle being fixed on the sphere, when the sleeve is placed against the sphere by sliding along the needle, the end 20 of the shoulder of the needle is released from the sleeve.

Enfin, le dispositif selon l'invention comporte un raccord de fixation 13 assurant la jonction entre l'aiguille 3 et la barre de structure 14. Le raccord est un arbre cylindrique de section circulaire fileté extérieurement aux deux extrémités 15, 16 et comporte un épaulement 17 intermédiaire entre les deux parties filetées 15, 16, de telle sorte que la partie filetée 15 pénètre dans le manchon taraudé 12 et que la partie filetée 16 coopère avec un taraudage pratiqué à l'extrémité de la barre de structure 14. Finally, the device according to the invention comprises a fixing connector 13 ensuring the junction between the needle 3 and the structural bar 14. The connector is a cylindrical shaft of circular section threaded externally at the two ends 15, 16 and has a shoulder 17 intermediate between the two threaded portions 15, 16, such that the threaded portion 15 penetrates into the threaded sleeve 12 and that the threaded portion 16 cooperates with a thread formed at the end of the structural bar 14.

De préférence, les diamètres extérieurs du manchon 6 de l'épaulement 13 du raccord, et de la barre 14 sont identiques et les longueurs des filetages' respectifs sont tels que
- la barre 14 vient s'appuyer sur l'épaulement 17 du raccord 13,
- lorsque le manchon est vissé et serré sur le raccord d'une part l'épaulement 7 du manchon s'appuie sur l'épaulement 5 de l'aiguille, d'autre part l'extrémité 20 de l'aiguille s'appuie sur l'extrémité 21 du raccord 17 assurant un contact rigide entre l'aiguille et le raccord}
- lorsque le manchon est vissé sur le raccords l'extrémité du manchon affleure l'épaulement 17 de telle sorte que les trois pièces manchon, raccord, barre soient sensiblement dans le prolongement l'une de l'autre.Preferably, the outside diameters of the sleeve 6 of the shoulder 13 of the connector, and of the bar 14 are identical and the lengths of the respective threads are such that
the bar 14 comes to bear on the shoulder 17 of the connector 13,
- when the sleeve is screwed and tightened on the connector on the one hand the shoulder 7 of the sleeve is supported on the shoulder 5 of the needle, on the other hand the end 20 of the needle is supported on the end 21 of the fitting 17 ensuring rigid contact between the needle and the fitting}
- When the sleeve is screwed onto the fittings, the end of the sleeve is flush with the shoulder 17 so that the three pieces of sleeve, fitting, bar are substantially in line with one another.

De manière préférentielle, les extrémités de l'aiguille et du manchon sont en forme de cône de sorte que lorsque les pièces sont assemblées le manchon et l'aiguille ne présentent qu'une seule surface conique orientée, le sommet du cône étant orienté vers la sphère. Preferably, the ends of the needle and of the sleeve are cone-shaped so that when the parts are assembled the sleeve and the needle have only one oriented conical surface, the top of the cone being oriented towards the sphere.

Le montage du dispositif d'assemblage selon l'invention s'effectue dans l'ordre suivant. The assembly of the assembly device according to the invention is carried out in the following order.

1) On visse le raccord 17 d l'extrémité de la barre de structure 14
2) On glisse l'aiguille 3 dans le manchon 6, et l'on visse l'aiguille dans la sphère par l'intérieur de l'aiguille.1) We screw the connector 17 to the end of the structure bar 14
2) The needle 3 is slid into the sleeve 6, and the needle is screwed into the sphere from the inside of the needle.

3) On dégage l'épaulement de l'aiguille en faisant glisser le manchon le long de l'aiguille. 3) The shoulder of the needle is released by sliding the sleeve along the needle.

4) On présente la barre munie du raccord devant l'épaulement, à quelques millimètres de l'épaulement, et l'on visse le manchon dans le raccord. 4) The bar with the connector is presented in front of the shoulder, a few millimeters from the shoulder, and the sleeve is screwed into the connector.

Il est essentiel de remarquer que la mise en place de la barre dans le dispositif d'assemblage ne nécessite pas de mouvement de la barre vers l'intérieur du dispositif. It is essential to note that the positioning of the bar in the assembly device does not require movement of the bar towards the interior of the device.

Il n'y a donc pas de mouvement de la charpente métallique. Chaque barre est mise en place par un léger mouvement transversal de présentation des pièces en-regard l'une de l'autre. There is therefore no movement of the metal frame. Each bar is put in place by a slight transverse movement of presentation of the pieces opposite one another.

Le dispositif selon l'invention ne comporte que des pièces simples, ne présentant aucune soudure. Il peut être construit avantageusement en alliage léger protégé de toute corrosion par oxydation anodique. The device according to the invention comprises only simple parts, having no welds. It can advantageously be constructed from a light alloy protected from corrosion by anodic oxidation.

De manière préférentielle, le diamètre des barres de structure est de l'ordre de la moitié du diamètre des sphères auxquelles elles sont reliées, donnant ainsi par exemple des barres de 20 à 80 mm de diamètre pour des sphères respectivement de 40 å 160 mm de diamètre.  Preferably, the diameter of the structural bars is of the order of half the diameter of the spheres to which they are connected, thus giving for example bars of 20 to 80 mm in diameter for spheres of 40 to 160 mm respectively. diameter.
