Abstract
The invention is embodied in a mini-blind which has a headrail and an array of slats suspended therefrom. The slats are raised, lowered and adjusted with a plurality of cords. The slats are generally free from apertures which extend through the slats. The cords used to lift the array of slats run along the outer edges of the slats. At least one of the ladder cords, which are used to adjust the angular orientation of the slats, engages notches formed in the edges of the slats. The invention also has a unique method of controlling the lifting cords as they extend through and out of the headrail. A basket/barrel assembly having a bent wire cord guide cooperates with cord locking and tilting mechanisms which are housed together at one end of the headrail.
