A screen system for deployment over a surface is disclosed herein. The screen system comprises a first screen structure (550) and a second screen structure (553). Each screen structure comprises a panel element (544a,554b) attached to at least one support element (501a,501b,503a,503b), wherein the at least one support element and the panel element are attached to and configured to be rollable about a rotor (516a,516b) configured to rotate about a longitudinal axis to provide for extension and retraction thereof along a direction generally perpendicular to the longitudinal axis. The rotor of the second screen structure is configured to be moveable relative to the rotor of the first screen structure.

A partition system has at least one pivot joint, each pivot joint having two pivot structures with partial circular cross-sections centered on a pivot axis. Each pivot structure engages with one of a plurality of wall panels and permits the engaged wall panel to pivot about the pivot axis. A linking structure extends between and joins the two pivot structures. A stop member extends outwardly from the linking structure to limit a range within which the wall panels can pivot about the pivot axis. Each of the wall panels has a pair of parallel tabs extending substantially perpendicularly from at least one end face of the wall panel. At least one parallel tab has an end flange extending inwardly toward the second tab. The end flange snap fit onto one of the pivot structures. Each of the wall panels is pivotally connected to the at least one pivot joint.

A method of assembling a partition against at least one support surface of a planar support, the partition comprising two main surfaces that are substantially parallel and connected for a contour, the contour comprising at least three edge surfaces, the assembly method comprising attaching at least one of the edge surfaces against at least one support surface using attachment means, the attachment means comprising at least one clip and at least one opening delimited by a contour configured to cooperate by snap-fitting with the at least one clip, the at least one clip being attached on one of the support surface or the edge surface in question, while the opening is formed on the other of the support surface or the edge surface.
