Abstract
An adjustable shade including first and second parallel headrails and an intermediate rail between the headrails with a foldable shade member attached to the intermediate rail and to one of the headrails. The shade member has rows of aligned openings therethrough and the headrails and intermediate rail have openings aligned with the rows of openings in the shade member. Tension cords extend through the rows of openings in the shade member and through the openings in the headrails and intermediate rail to guide the intermediate rail and shade member during movement between open and closed positions. The draw cords are attached to the intermediate rail and extend through the rows of openings in the shade member and through the headrails, and the draw cords have an operating portion that extends between the headrails and which can be grasped to move the intermediate rail in both directions relative to the headrails. Guide bushings are provided in the openings in the headrails and guide buttons are mounted in the guide bushings. The guide buttons have a notch to allow the draw cords to pass through the openings in the guide bushings and a tension cord passage spaced from the notch for receiving the tension cords to maintain the draw cords and tension cords separated as they pass into and out of the head rails.
