Structure with hollow or partially hollow structural elements, with modular and improved system of joints

A structure (S) with hollow or partially hollow structural elements (P1, P2, P2′), for shading or covering structures or adapted to be used for furniture, comprising:

• a plurality of said hollow or partially hollow structural elements (P1, P2, P2′);
• and
• a system of joints (1, 2, 1′, 2′, 3, 4, 5, 6) configured to join said structural elements (P1, P2, P2′) to one another,
• wherein each one of said joints (1, 2, 1′, 2′, 3, 4, 5, 6):
• is suited to be axially fitted in said structural elements (P1, P2, P2′),
• is essentially prismatic in shape, with a cross section having a shape essentially matching a cross section of said structural elements (P1, P2, P2′), and
• wherein each one of said joints (1, 2, 1′, 2′, 3, 4, 5, 6) comprises one or both of:
• one or more through holes (14, 24) at least in a longitudinal direction (X), corresponding to a direction of insertion in said structural elements (P1, P2, P2′), or
• one or more through or blind holes (15) according to one or more transverse directions, said holes (14, 24, 15) in the longitudinal and one or more transverse directions being suitable for insertion of fixing elements (V) that fix at least two of said joints (1, 2, 1′, 2′, 3, 4, 5, 6) to each other, thereby also joining the structural elements (P1, P2, P2′) in which the at least two of said joints are inserted.
