Abstract:
A sliding rotating leaf system comprising:a guide rail; a plurality of area elements each having at least one roller movable on said guide rail, each of said area elements being movable on said guide rail between a folded position and an unfolded position; a plurality of coupling elements arranged on said guide rail; and a coupling piece arranged on each of said area elements, a largest diametral dimension of a circular segment of each of said coupling pieces being equal to a distance between centers of adjacent one of said coupling elements whereby each of said coupling pieces serves as a stop for positioning said coupling piece of an adjacent one of said area elements in alignment with a respective one of said coupling elements; said coupling piece of each of said area elements engaging a respective one of said coupling elements on said guide rail when said area element is in said folded position to prevent translatory movement of said coupling piece relative to said respective coupling element while permitting rotary movement of said coupling piece relative to said respective coupling element; said coupling piece of each of said area elements rotating relative to said respective coupling element upon initiating movement of said area element from its folded position to thereby disengage said coupling piece from said respective coupling element to enable translatory movement of said area element toward said unfolded position as said at least one roller of said area element rolls on said guide rail.
