Articulated structure

An articulated structure, comprising a central frame and at least three satellite frames surrounding the central frame, wherein the central frame and the satellite frames extend in a common main plane and each of the satellite frames is coupled to the central frame by a pair of couplings, of which a first coupling comprises a first support that is mounted to the central frame through a first pivot and to the satellite frame through a second pivot, wherein at least one of the first and second pivots has a single pivot point, such as a ball joint, and the other one of the first and second pivots has at least one pivot axis, and of which a second coupling comprises a second support that is mounted to the central frame through a third pivot and to the satellite frame through a fourth pivot, wherein at least one of the third and fourth pivots has a single pivot point, and the other one of the third and fourth pivots has at least one pivot axis, hence forming an imaginary axis of rotation (IA1, IA2) through the pivot point of one of the first and second pivot and the pivot point of one of the third and fourth pivot.
