<p>A closure device for closing off, at least in part, a cavity (1) that is open at its top, includes a set of panels (3) suitable for forming a closure cover and cover support element (13). Each panel has link elements for linking to the neighboring panel(s) (3) so as to enable the set of panels (3) to go from a stacked configuration, in which they are superposed on one another in order to open up the opening in the cavity (1) at least in part, to a deployed configuration, in which the panels of at least some of the set of panels (3) extend in alignment with one another while bearing against the cover support element (3). The device further includes elastically deformable elements (4) suitable for being compressed by the panels when the set of panels (3) are in the stacked configuration.</p> |
