An improved roller shade system provides increased support, additional adjustments and/or increased safety. The slip plate allows the brake to slip forward and minimize damage to the clutch spring when a user pulls too hard on the hembar. The center drive mechanism extends through a bracket to allow the drive shaft to distribute power in both directions and drive two shade tube simultaneously. The tube adapter absorbs force from the spinning shade tube to minimize damage to the other components and the bead chain. The sprocket has a back wall supporting the sprocket, allowing the sprocket 130 to rest on the back flange of the sun gear to minimize pressure on the gears. An adjustment arm is adjusted to help level the shade band. The shade bands may be removed without disturbing the other shade bands in the system. A height of a hembar may be adjusted by rotating a rod within the hembar.

The Invention relates to the field of roller shutter, discloses the automatic landing or rising type roller shutter, the main point of its technical solution is to include the shell, the shell is set with a disc, the side of the shell is set with an extension tube, the side of the disc is set with an extension body, at least part of the extension body extends into the extension tube, through the user pulling the rope body, drive the roller shutter rise or fall, in each with any start-stop structure or can advance to apply the force of the spring roller shutter. The rope body is provided with a pull rod in the part of the rope body that extends out of the shell, and the rope body is pulled by the pull rod to facilitate the user's grip and prevent the rope body from knotting and other situations.

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.

A spring roller blind which can be started and stopped at will, including a transverse rod and a chuck, wherein the transverse rod is fixedly connected to the chuck, a first torsion spring is arranged on the transverse rod, and one end of the first torsion spring is fixedly connected to one end of the transverse rod away from the chuck. When pulled downwards, the roller blind can be stopped at any position by the friction between embracing springs and a pipe plug; and when a pull ring is pulled, the roller blind can be retracted automatically under the action of the restoring force of the first torsion spring.

An enclosure for an endless loop blind control element for operating a blind operating mechanism, wherein the enclosure extends from a first end to a second end and said endless loop blind control element is enclosed within said enclosure from said first end to said second end and connected to said blind operating mechanism.
