ABSTRACT:
A covering for an architectural opening includes a fixed stationary rail at one end of a plurality of slats and a movable rail at the opposite end of the slats with the slats being movable to and from the fixed rail to create extended and retracted positions of the architectural covering. At least one continuous drive cord is arranged in a loop with both its ends attached to the movable rail and at least one fixed cord return guide is provided. A drive spool adapted to be selectively rotatable in opposite directions of rotation and is operatively engaged with the drive cord so that the drive cord can be wrapped around the drive spool to establish driving engagement. An adjusting mechanism is provided for adjusting the plurality of slats and a drive shaft for rotatably driving the adjusting mechanism in opposite directions with the adjusting mechanism being adapted to rotatably engage the drive spool and wherein a lost-motion drive connection is operatively included between the adjusting mechanism and the drive spool.
