Abstract: A dual shade apparatus comprises a first shade, which may be a Roman or natural woven shade, and a second shade, which may be a cellular shade, coupled to each other in a back-to-back arrangement with one or more dual channeled couplers. Any lift cords employed in the apparatus are concealed in between the pair of shades so as to prevent any direct contact. No portion of any employed cords is exposed or accessible for direct or inadvertent contact, thereby enhancing safety in operating the apparatus. The coupler has a double-C configuration to receive corresponding retaining mechanisms of the front and rear shades. A head rail houses a lifting mechanism. Each lifting cord extends from the lifting mechanism, in between the two shades, and down to a bottom rail. The dual shades are drawn down or retracted in unison by pulling or pushing up the bottom rail.

Abstract: An adjustable side channel assembly for use with screens and shades includes a pair of adjustable side guides, each laterally adjustable with respect to a corresponding side frame. Each side guide may be moved to a desired position and then secured to the side frame with a fastener. Each side guide includes an axial fabric retainer configured to receive a side gimp of a shade. Each fabric retainer is loosely retained in a hollow channel within the side guide and laterally movable to enable both sides of a shade to lie substantially parallel when the shade is drawn. A take-up mechanism includes dual rollers with the outer roller having a shorter width to provide space for the side gimps to roll up and not spiral out when the shade is taken up.

Abstract: A track system includes a track having a central vertical member with opposing vertical surfaces. A pair of lower horizontal rails extend from the vertical member and do not block the vertical surfaces. Flexible carriers are individually removable from the track. Each carrier includes a flexible frame coupled to a pair of wheels configured to roll on the rails. The carriers may each include a hanger or other connector for supporting privacy structures such as curtains, drapes, window treatments, and dividers. The tracks may be bent and coupled end to end to form a complete assembly for facilitating privacy in a room.
