Abstract (en)
[origin: WO2021009424A1] The invention relates to a lattice structure comprising a plurality of longitudinal members extending parallel to one another along a main direction of extension and crossmembers (9) distributed along the main direction of extension for mechanically connecting the longitudinal members in pairs so as to form a plurality of polygons (11) each contained in a plane perpendicular to the main direction of extension. According to the invention, each crossmember (9) connecting two longitudinal members comprises a first half-crossmember (9a) with a first end connected to one of the two longitudinal members so as to be able to pivot about a first axis (X1-X'1) and a second half-crossmember (9b) with a first end connected to the other of the two longitudinal members so as to be able to pivot about a second axis (X2-X'2). The two half-crossmembers are connected to one another by an articulating hinge (13) allowing relative rotation of the two half-crossmembers (9a, 9b) about a third axis (X3-X'3). The first, second and third axes are parallel to one another and orthogonal to the main direction of extension, allowing the lattice structure and each crossmember (9) to move from an extended position to a folded position in which the first and second half-crossmembers (9a, 9b) of each crossmember (9) extend substantially parallel next to one another along said main direction of extension.
