Abstract: A cordless roller blind includes a roller tube, a blind fabric wound around the roller tube, and at least one brake device. A coil spring is arranged in the roller tube, and the torsion of the coil spring changes as the roller tube rotates. The torsion force of the coil spring, the friction force provided by the brake device and the weight of a hanging portion of the blind fabric are mutually balanced, so that the blind fabric remains stationary at any position without an external force. When the external force pushes the blind fabric to move upward, pressure acting on the brake device decreases as the external force offsets the weight of the blind fabric, and the friction decreases accordingly, and the torsion force of the coil spring drives the blind fabric to wind up.

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.
