A sun protection apparatus includes a shading device, including an upper bar, a lower bar and a screen disposed between the upper and lower bars. The apparatus also includes a motorized drive device, designed to deploy and fold away the screen, including a first electromechanical actuator, configured to move the upper bar, a second electromechanical actuator, configured to move the lower bar, and a control unit, configured to control the first and second actuators. The control unit controls the first actuator so as to move the upper bar then the second actuator so as to move the lower bar depending on the position and/or movement of the upper bar, or vice versa.

A window blind includes a housing, a slat assembly, a slat angle adjusting device, and a first cord. The slat assembly is provided below the housing, and has multiple slats and a bottom end portion. The slat angle adjusting device includes a rotating shaft assembly provided in the housing, and a ladder assembly which includes at least two ladders connected to the rotating shaft assembly for turning the slats. The first cord passes on a front or a rear side of the slats, and connects the rotating shaft assembly and the bottom end portion. Throughout the duration of the rotation of the rotating shaft assembly, the first cord and a warp, which belongs to the ladder assembly and on the same side as the first cord, are both reeled into or out of the housing concurrently, and the slats and the bottom end portion are all rotated concurrently as well.

Systems and methods for determining proximity of architectural structure coverings. A user device receives a broadcast signal from each of a plurality of architectural structure coverings. An ordered list of the plurality of the architectural structure coverings is then maintained based on the broadcast signal. At least a portion of the ordered list is displayed on a display of the user device.

A curtain cord winding device includes a base, a cord winding mechanism rotatably mounted to the base, and a drive mechanism. The cord winding mechanism includes a main reel fitted about a drive shaft of the drive mechanism, and a secondary reel. The main reel includes a first winding segment for winding a cord, and a screw segment screwed to a screw hole of the base. The main reel and the secondary reel are coaxially arranged and fixed in turn. The secondary reel includes a second winding segment, and a first connecting member. An end of the first winding segment away from the screw segment and an end of the second winding segment away from the first connecting member each is provided with a second connecting member. The first connecting member is fixed to the second connecting member in an axial direction.

A control rope guide device for a window curtain assembly includes a bottom part and a top part. The top part is connected to the top of the bottom part. The control rope guide device is cooperated with the window curtain assembly to separate two control ropes apart from each other so as to smoothly expand or lift the curtain.
