The invention concerns a tube assembling device consisting of hub-carriers and hubs for erecting three-dimensional structures. Said hub-carriers consist of two pairs of half-rings (8 and 9), bearing tongues (1 and 14) offset by 90~ along an antero-posterior axis and linked by four connecting lugs (10 and 11), they support radial hook-shaped expansions (5, 6, 7). Said hub-carriers can link two tubes in a fixed or balanced position, can be fixed at the tube end, can be fixed along a tube and support hubs. The hubs support tongues (3) which are positioned folded or unfolded inside the tubes used for the construction of the radial expansions into rings (4) and catching teeth (5, 6 7) internal to said rings (4). The assembly enables the hubs and hub-carriers to be linked by tubes or preferably elastic links and constitute by folding or combining the hubs and hub-carriers nodes for modelling structures of numerous types from a reduced number or elements.

La présente invention concerne un dispositif d'assemblage de tubes composé de "porte-moyeux" et de "moyeux" dans le but de construire des structures tridimensionnelles. Ces "porte-moyeux" sont composés de deux paires de demi-anneaux (8 et 9), portant des languettes (1 et 14), décalées de 90· selon un axe antéro-postérieur et reliées par 4 pattes de liaison (10 et 11), ils portent des expansions radiales en forme de crochet (5, 6, 7). Ces "porte-moyeux" peuvent relier deux tubes dans une position fixe ou en équilibre, se fixer en bout de tube, se fixer le long d'un tube et porter des "moyeux". Les "moyeux" portent des languettes (3) que l'on positionne pliés ou non-pliés à l'intérieur des tubes utilisés pour la construction, des expansions radiales en anneaux (4) et des "dents" d'accrochage (5, 6, 7) internes à ces anneaux (4). L'ensemble permet de relier les "moyeux" et les "porte-moyeux" par des tubes ou des liens préférentiellement élastiques et de constituer par pliage ou combinaison des "moyeux" et des "porte-moyeux" des n.oelig.uds permettant de modéliser des structures très variées à partir d'un nombre réduit d'éléments.
