Abstract: A pre-loadable spring roller blind, including a spring bar, a limiting spring, a spring tail plug and a limiting pipe plug sleeve. By arranging the spring tail plug into the first rotating plug and the first adjusting core and arranging the holding spring between the first rotating plug and the first adjusting core, the first adjusting core can be rotated to store the force for the limiting spring. After the torsion force is stored, the spring may not discharge the force when released. When the limiting pipe plug sleeve is used for loading, as long as the tail of the spring bar is fixed, the limiting pipe plug sleeve is rotated to store a force for the limiting spring. After the force is stored, the limiting pipe plug sleeve can be released at any time and the limiting pipe plug sleeve is kept fixed.

Abstract: The present invention relates to sunshades and methods of constructing sunshades, particularly, sunshade canopies installed at a fixed location in the temperate zones. In a first aspect of the invention, a sunshade element is configured such that the sunshade element is viewed from a reference shade point as a thin profile between adjacent apertures over predetermined days in winter, thereby maximising the admission of sunshine to the shade area; and configured such that the sunshade element presents the maximum or near maximum breadth of its during predetermined days in summer; resulting in the admission of sunshine in winter and the blocking of sunshine in summer. During the spring period winter, sunshine is gradually replaced by summer shade, and during the autumn period, summer shade is replaced by winter sunshine, such that the sunshade elements provide effective blocking and admission of sunshine to the shade area over the annual solar cycle.

Abstract: A controller assembly for a window blind includes a drive mechanism and at least one transmission mechanism with a gear unit and a transmission unit.

Abstract: The present disclosure discloses a stroke head of a drive apparatus for driving curtain lifting, comprising a body, and the body is internally provided with a circuit board where a power switch is disposed, and the power switch is exposed outside the body. The power switch disposed on the stroke head brings the effects of facilitating switching on/off a power supply for people and saving electricity. When the stroke head after manufactured is assembled with a tubular drive unit and then warehoused, the power switch can be switched off to prevent power depletion, thereby ensuring sufficient electricity quantity left in the power supply after the power supply is assembled and switched on to debug the drive apparatus, and maintaining normal operation of the drive apparatus. In addition, a closed power supply is beneficial to lowering its explosion risk in transportation and improving safety.

Abstract: A roller blind assembly includes a blind roller, a clutch assembly that includes a bracket engagement member, and a pre-torsioned spring assembly that includes a spring. The pre-torsioned spring assembly is positioned in an interior cavity of the blind roller, and exerts a torque proportional to a preset torsion of the spring to promote rotation of the blind roller relative to the bracket engagement member. Rotation of the blind roller relative to the bracket engagement member in a first direction decreases torsion in the spring while rotation of the blind roller relative to the bracket engagement member in a second direction increases torsion in the spring. The pre-torsioned spring assembly is preferably selected from a group of at least two pre-torsioned spring assemblies, each spring assembly having a different spring preset torsion.

Abstract: 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.
