An adjustable structure comprises two panels (24) carrying at adjacent edges respective members (11, 13) each having ribs (14) and grooves interengaging with one another after the fashion of gear teeth so that the members (11, 13) can roll relative to one another about respective axes parallel with the panel edges. Each member (11, 13) carries within a respective longitudinal passage (33) resilient spindle elements (35) disposed substantially coaxially with the member (11, 13) and resiliently displaceable, at least in part, transversely of said axis. The members (35) are held together by connecting links (46) providing hooks receiving respective resilient spindle elements (35) of the two members, slots (32) being formed in the members (11, 13) for passage of the links. The configuration of the links (46) and the spindle elements (35) is such that resilient displacement of spindle elements (35) transversely of the axes, towards one another, is necessary to apply the links to or detach the links from the spindle elements. The construction described allows quick and simple assembly of various adjustable structures incorporating such panels, whilst ensuring reliable interconnection of the panels and adjustment of the structure. |
