Device for assembling tubes into three-dimensional structures comprises hubs, hub carriers and spindles, hub carriers formed by folding succession of cone or cylinder sections

摘要

The assembly device comprises hubs, hub carriers and connection spindles. The hub carriers comprise three concentric folds obtained by folding a succession of the cylinder or cone sections aligned with alternate convexities connected by hinge lugs (12,17). The external fold of the hub carrier has an annular gutter (6) with its distal edge (7) raised relative to the proximal edge (5).
