Abstract

A first track assembly is adapted to be mounted to a top of a window opening. A plurality of first cord support assemblies are slidably mounted within the first track assembly. A plurality of second cord support assemblies are slidably mounted within a second track assembly. A plurality of columns of panels is provided, each column being strung between a pair of the first and the second cord support assemblies. A vertical opening and closing mechanism is provided for pulling the second track assembly toward the first track assembly and for lowering the second track assembly away from the first track assembly, thus collapsing and extending each column of panels. A horizontal opening and closing mechanism is provided for simultaneously drawing the first support assemblies together and drawing the second support assemblies together, and for simultaneously separating at pre-determined equal distances the first support assemblies and separating at pre-determined equal distances the second support assemblies, thus drawing the columns of panels together and separating the columns of panels. A vertical pivoting mechanism is provided for pivoting all of the panels simultaneously about a horizontal axis of each panel. A horizontal pivoting mechanism is provided for pivoting all of the panels simultaneously about a vertical axis of each panel.
