Abstract: A window covering system that includes an elongated tube configured for a window covering to be wound around the tube, a clutch assembly that includes a pulley and a power spring having a first end engaging the pulley and a second end that is stationary, a limiter assembly, a booster assembly arranged between the clutch assembly and the limiter assembly, a cord arranged at least partially within the clutch assembly, and a wand fixed to the cord to selectively raise and lower the window covering.

Abstract: 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.

Abstract: An universal automatic tensioning system, for roller blinds and awnings with side rails, comprising a crossbar (2) equipped with a spring pin (6) that can move along a side guide (3) that defines the rail for the shift of the awning (1), characterized in that it includes one or more fixed clip(s) (4) that can be hooked by the spring pin (6) causing the locking of the roller blind (1); a further movement of the awning's crossbar (2) will force the spring pin (6) engaging with a mobile flap (5) that works as a sort of “bridge” for the spring pin (6), causing the unlocking of the crossbar (2), so as to realize the setting for the automatic tensioning of the roller blind (1).
