发明名称 Two and three position over-under window shade
摘要 Two and three position over-under shades having at least three horizontal rails separated by pleated blinds. Single or double lift cords are provided to control the raising and lowering of the blinds. Material for the individual blinds may be any material which exhibits suitable properties and meets the aesthetic requirements of the user, this includes translucent single pleated fabric, honeycomb pleated material providing significant thermal insulation, or even insect screen. A blind may be omitted leaving the rail below suspended by its lift cord and providing an opening without raising the entire shade. The design allows a choice of window coverings to be in place and provides different window coverings while maintaining a uniform appearance.
