Three-dimensional foldable device, particularly for advertising and exhibition purposes, comprising at least one individually foldable and expandable structural section (4) which comprises a number of frame elements (5, 7) which are interconnected, in addition to which said frame elements (5, 7) comprise at least three stand elements (5) which are essentially parallel to a longitudinal axis (L) of the structural section (4) and located at a periphery of a cross section of the structural section (4) at right angles to the longitudinal axis (L), in addition to which the stand elements (5) are interconnected along said periphery, each connection between two stand elements (5) comprises at least two connection elements (7), one end of each connection element (7) is connected to one stand element and the other end is connected to another stand element, at least one end of each connection element (7) is movable in the axial direction of the stand element to which it is connected, and each connection element (7) forms an angle (A) to the respective stand elements (5), in addition to which the stand elements (5) are arranged so that they move radially inwards when said angle (A) decreases, whereas they move radially outwards when said angle (A) increases. |
