Abstract A collapsible structure is provided comprising pairs of parallel posts interconnected by pairs of expansion links-like connecting rods. Connecting rods of each pair have their centres pivotably connected, whereas their outer ends are pivotably connected with the corresponding posts and wherein at least one outer end of each rod is slideable along the corresponding post. The pairs of parallel posts can be superimposed while corresponding posts are at their meeting ends hingedly connected for an accordian-like collapsability in the vertical plane. Further pairs of parallel posts can be laterally positioned while adjoining posts of adjoining pairs of posts are hingedly connected for a substantial change in the angle enclosed by the planes extending through said pairs of posts.
