In one aspect, a roller shade assembly for an architectural opening may generally include a first roller, a second roller and a looped shade extending around the first and second rollers, The looped shade may include at least one outer shade web forming a continuous loop around the rollers. In addition, the roller shade assembly may include an inner shade web configured to be wrapped around the first roller or the second roller such that the inner shade web is positioned within the continuous loop. The inner shade web may be coupled to the outer shade web(s) at a location along an inner perimeter of the continuous loop. Additionally, rotation of the first roller and/or the second roller in an unwinding direction may result in the inner shade web being unwound from the first roller or the second roller along the inner perimeter of the continuous loop.

A window covering includes a liner attached to a first rail and window covering material attached to the first rail and the liner such that the window covering material is moveable from a retracted position to an extended position when the liner is moved from its retracted position to its extended position. The window covering material can be configured to define a first number of folds when the window covering material is moved to the retracted position of the window covering material. The liner can be configured to define a second number of folds when the liner is moved to the retracted position of the liner. The second number of folds can be a number of folds that is at least 50% larger than the first number of folds formed in the window covering material when it is moved to its retracted position.

An extensible curtain rail includes a rail main body, more than one connection seat and a decorative panel. The decorative panel and the rail main body are assembled and connected with each other by means of the connection seat. The connection seat can be inward contracted or outward extended to adjust the gap between the decorative panel and the rail main body in accordance with different sizes of curtain assemblies to facilitate installation thereof. The decorative panel is detachable from the rail main body to provide larger installation space and more quickly install the curtain assembly.

The present invention relates to: a light-blocking fabric usable in blinds for shading or wind protection. The light-blocking fabric includes two light-shielding parts made of a non-transparent fabric, and a light-transmitting part located between the two light-shielding parts, and attached to each of the two light-shielding parts along a longitudinal direction. The light-transmitting part starts attaching to each of the two light-shielding parts at the position that is at least half of a width of each of the two light-shielding parts away from an inner end of each of the two light-shielding parts in a width direction. The longitudinal direction along which the light-transmitting part is attached to each of the two light-shielding parts is perpendicular to the width direction of the each of the two light-shielding parts.

A light-adjustable shade structure includes a top beam, a plurality of dimmable curtains, and a plurality of positioning devices. The top beam is provided with a plurality of tracks, the tracks are respectively equipped with a sliding seat connected and driven by each other. The dimmable curtains are staggered from top to bottom with a plurality of light shielding parts and a plurality of light transmitting parts, the dimmable curtains are wound and connected respectively between an upper shaft rod and a lower shaft rod to form a double-layer structure. The positioning devices are installed on the dimmable curtain to adjust the dimmable curtain to form In the transparent or light-shielding state. The dimmable curtain is pushed, pulled, or closed along the trail of the top beam, and the effect of adjusting light can be achieved by staggering or facing the light shielding part and the light transmitting part.

The present disclosure provides a window covering system comprising a head rail, a roller tube attached to one end of a horizontal roll shade, a fixed tube or holder attached to the other end of the horizontal roll shade, and a moveable tube positioned between the roller tube and the fixed tube or holder. The roll shade forms a loop between its ends. The system includes a mechanism coupled to the roller tube to selectively rotate the roller tube and thereby move the roll shade between a deployed position and a retracted position. A device is provided to move the moveable tube along the head rail. The system allows for horizontal deployment and retraction of the roll shade while maintaining proper tension and alignment.

The present invention relates to a combination roller blind wherein a fine adjustment means is provided behind an upper face of a headrail, the adjustment means causing an end of a blind sheet wrapped around a blind roll and an end opposite thereof to be fine-adjustably wrapped and unwrapped. When the blind is installed on a ceiling or a window frame to completely conceal the bottom edge of the window so that a bottom edge of a weight is adjoining a bottom sill of the window frame, and a portion of a light-transmissive section of the blind sheet is not overlapped, the opposite edge wrapped around the blind roll of the blind sheet can be fine-adjusted by rolling so that the light-transmissive section alternates with and is not completely overlapped by a light blocking section, allowing for complete shading to be achieved while completely concealing the bottom edge of the window.
