(54) Window covering assembly with tension cords


(57) A window covering assembly for an architectural opening such as a window. The window covering assembly comprises a first or top movable rail having left and right longitudinal ends, a second or lower movable rail having left and right longitudinal ends, blind material connected to the two rails and extendible and retractable between the two by moving one or both rails away from or toward each other and a pair of first and second main tension cords routed in mirror image one to another through and along the top movable rail, the blind material and the bottom movable rail. The first cord of the pair of the first and second main tension cords is routed to enter the top movable rail at a first entrance point which is adjacent one of the left or right longitudinal ends of the rail and spaced a first length measured from said end. The first cord is then routed through or along the rail to exit the top movable rail at a first exit point which exit point is spaced at a second length from the same one of the left or right longitudinal rail ends as the first entrance point. The first length exceeds the second length.
