The present disclosure relates to an adjustable roller shade. In certain embodiments, the adjustable roller shade includes: a roller shade fabric winding shaft, a roller shade fabric wound on the roller shade fabric winding shaft forming upper edge of adjustable roller shade, a weight bar attached to bottom of roller shade fabric forming lower edge of adjustable roller shade, a pair of movable pulleys, two pairs of upward lifting ropes and downward pulling ropes, four winders, four driving motors, and a controller. The controller controls rotations of four driving motors, independently and in concert. Each of the four winders is independently driven by four driving motors respectively. Rotations of four driving motors cause rotations of four winders. Ups and downs of the upper edge and the lower edge of the adjustable roller shade can be achieved by controlling the rotational directions of the four winders, separately and independently.

In one aspect, a covering for an architectural structure includes a multi-panel shade formed form a plurality of panel sections arranged relative to one another to form a continuous sheet, with at least one of the panel sections having different shade properties from the other panel section(s) forming the multi-panel shade. By adjusting the extent to which the panel sections are exposed along the drop length of the covering, the covering may be configured to provide various different shade configurations.

Present disclosure relates to several adjustable roller shades. Adjustable roller shade includes: roller shade fabric winding shaft, weight, movable pulley, loop traction rope, two winders and two tensioning wheels. A roller shade fabric is wound on roller shade fabric winding shaft forming upper edge of adjustable roller shade. Weight is attached to bottom of roller shade fabric forming lower edge of adjustable roller shade. Movable pulley is fixedly attached to one end of the roller shade fabric winding shaft. Loop traction rope is wound around the movable pulley, two winders and two tensioning wheels. One or more driving motors drive the pair of winders to rotate in different combination of directions to raise or lower both upper edge and lower edge of adjustable roller shade, resulting the adjustable roller shade to be opened or closed freely from both upper and lower edges of the adjustable roller shade.

Retractable roof and/or wall panels are disclosed herein. Such panels may be used as roof or wall portions for tents or other temporary structures allowing for variable outdoor exposure and easy transitions from indoor to outdoor spaces.

Present disclosure relates to an adjustable roller shade. Adjustable roller shade includes: roller shade fabric winding shaft, weight, movable pulley, loop traction rope, a first and a second winders, and a first and a second tensioning wheels. Roller shade fabric is wound on roller shade fabric winding shaft forming upper edge of adjustable roller shade. Weight is attached to bottom of roller shade fabric forming lower edge of adjustable roller shade. Movable pulley is fixedly attached to one end of the roller shade fabric winding shaft. Loop traction rope is wound around the movable pulley, the first and second winders, and the first and second tensioning wheels. A driving motor drives first winder to rotate in different combination of directions to raise or lower upper edge and lower edge of adjustable roller shade, resulting adjustable roller shade to be opened or closed freely from both upper and lower edges.

A retractable curtain system is provided and includes a curtain support system, a curtain, and a retraction system. The curtain support system includes a pair of outer walls and an upper frame to provide a curtain receiving space. The curtain covers the curtain receiving space and includes a first non-transparent panel and transparent panel connected to the first non-transparent panel. The retraction system is connected to the curtain to lower and raise the transparent panel.
