<p>The support e.g. parallelepiped articulated polyhedral box, has a polyhedral sleeve with articulation edges and retractable pivotingly maintenance walls e.g. retractable maintenance flaps (15, 16), where the polyhedral box is fixed between a folded flat state and an unfolded functional state and opened for receiving an object in a unique compartment. The maintenance walls are strutting walls that are retractable between a floor surface (5) and a ceiling surface (3) to form a force descent.</p> |
