摘要： 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.

摘要： A desired range of lift force to raise a window shade is used to select the window shade hardware such as, for example, the optimal LAM. A desired lift force may be 5 pounds for ADA compliance. However, if the user wants to exert less effort to lift the window shade, the user may request an increased lift force of 6 or 7 pounds. Therefore, if a lift force range between 3-8.5 pounds is desired, the system selects the optimal LAM to maintain and guarantee that the lift force required to operate the shades will not exceed the desired range of between 3-8.5 pounds.

摘要： The support connector system includes a first shade band having a support connector and a lock that receives the support connector. The lock includes a first opening in a first position, wherein the first opening is configured to receive the support connector and configured to restrict rotation of the support connector. The lock includes a second opening in a second position, wherein the second opening is configured to receive the support connector and configured to allow rotation of the support connector.

摘要： A safety device for a window shade system comprising a shade tube having a first end mounted to a first bracket 100 and a second end mounted to a second bracket. The system also includes a first plurality of catchpins 110 mounted to the first bracket, wherein the first plurality of catchpins 110 are mounted below the first end of the shade tube. In response to the first end of the shade tube disengaging from the first bracket, the first plurality of catchpins 110 catch the first end of the shade tube and prevent the first end of the shade tube from further falling.

摘要： The geared window shade bracket comprises a sprocket having a ring gear on an inside circumference of the sprocket; a chain configured to be engaged with the sprocket such that, in response to pulling on the chain, the sprocket rotates; a sun gear that is configured to be restricted from rotation; one or more planet gears configured to rotate around the sun gear, wherein the one or more planet gears interface with the ring gear; and a planetary carrier configured to mate with the one or more planet gears. In response to the chain being pulled, the sprocket rotates, causing the planet gears to rotate, causing the planetary carrier to rotate, causing the hub to rotate, and causing a shade tube to rotate.
