The invention concerns a tube assembling device consisting of hub-carriers a nd 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) whi ch 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 link ed 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. |
