发明名称 3-Way blind systems
摘要 A 3-way blind system for windows comprising an upper frame with: internal gearing; internal roller assemblies; a cord system; an upper and lower slat module comprising rotatably-alignable slats; an upper-housing; and a lower valence. The upper and lower slat modules operate either independently or in cooperation depending on the position of the selector to open the upper slat module to allow ambient light entrance and close the lower module for privacy, or to open the lower slat module for visibility and close the upper to limit bright ambient light from entering through the window. A third selector position may cause an internal gearset to work in unison to open or close all modules simultaneously.
