Abstract
A closure includes a plurality of vertical panels suspended from an overhead support and successively joined to one another by interlocking, alternate outer and inner pivot elements attached to the panel lateral edges. When the closure is collapsed the panels are folded about the pivot elements into a stacked, parallel diposition. Improved articulation between the panels is achieved by means of unique outer and inner pivot element components including respectively, a curved groove and a curved arm, both describing an arc of approximately 270.degree.. Female elements on the base of each pivot element cooperate with mating male elements joined to each panel lateral edge to allow ready assembly therebetween, with the panels themselves comprising either metal and/or a plastic composition.
