The invention provides a roller blind device with stepless adjustment comprising a roller blind base, a reel unit pivotally disposed on the roller blind base, and a blind fabric assembled on the reel unit, the reel unit comprises a first positioning unit, a second positioning unit, an outer tube accommodates the first positioning unit and the second positioning unit, a rotating shaft is assembled with the first positioning unit, and a first elastic member is disposed on the rotating shaft. Thereby, after a user combines the reel unit assembled with the blind fabric and the roller blind base, the user can drive the connected first elastic member to contract or loosen by adjusting the first positioning unit, so that a counterweight relationship between the reel unit and the blind fabric can be adjusted to achieve the roller blind device with stepless adjustment capable of adjusting a counterweight relationship.

Disclosed herein is a system for a window cowering. The system may comprise an elongate tube around which the window covering is able to be wound, first and second mounting members each comprising first and second spaced projections that extend from an internal wall of the elongate tube, and a reducer mounted to the first end of the elongate tube that includes first and second recesses that are configured to receive the first and second mounting members respectively to enable the reducer to be fastened to the first end of the elongate tube.

A counterbalancing device for a roller shade having a flexible sheet member and a roller shaft coupled to the flexible sheet member includes a stationary rod extending within the roller shaft, with the rod including a first end and a second end opposite the first end. The counterbalancing device also includes a rod adjuster coupled to the first end of the stationary rod and a spring winder positioned adjacent to the first end of the stationary rod. The rod adjuster is configured to selectively rotate the stationary rod and the spring winder is configured to rotate with the roller shaft. Additionally, the counterbalancing device also includes a spring having a first spring end coupled to the spring winder such that the first spring end rotates with the spring winder, and a second spring end coupled to the stationary rod such that the second spring end rotates with the stationary rod.

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.

A window shade mounting system for use with a curtain wall structure comprising: a mounting plate secured to a building material and the mounting plate is disposed in a cavity defined by a curtain wall assembly, the building material, a fire block; a support plate removable carried by the mounting plate; a bracket attached to the mounting plate having a first end configured to bear against the mounting plate; a member included in the bracket wherein the member is configured to engage a roller window shade assembly and the member configured to limit rotation of at least a portion of the roller window shade assembly; a passage defined in the bracket for receiving a wire that travels from the cavity, through the passage and connects to a roller shade assembly motor included in the roller window shade assembly; and, a decorative plate attached to the support plate.
