An apparatus supports two blind rollers from a headrail in one of at least eight configurations. Each blind roller has a first end coupled to a first blind control mechanism and a second end coupled to a second blind control mechanism. The apparatus includes a bracket having a top flange for coupling the bracket to an end of the headrail. An inner face of the bracket has an upper engagement projection configured to secure at least one of: the first blind control mechanism for the upper blind roller in one of two mechanism orientations, and the second blind control mechanism for the upper blind roller. The inner face also has at least two lower engagement recesses, each configured to receive a lower engagement connector, the projection configured to secure at least one of the first blind control mechanism and the second blind control mechanism for the lower blind roller.

Sunscreen assembly for an open roof construction in a vehicle of the type includes a flexible sunscreen having a center part and two opposed longitudinal edges connected to the center part and folding lines along which the longitudinal edges fold inwardly and whereby the center part of the flexible sunscreen comprises at least one layer of cloth. The sunscreen assembly further comprises a rotatable winding shaft configured to wind and unwind the sunscreen at a first one of its transversal edges, two opposed longitudinal guides configured to receive therein and guide corresponding ones of the inwardly folded longitudinal edges of the sunscreen, and wherein the folding lines are formed substantially by at least one respective incision made in the center part of the sunscreen along which the longitudinal edges are folded inwardly.

A blind assembly includes first and second side seats, a rotatable winding shaft, a shade member wound on the winding shaft, and a winding device. The winding device has a fixing unit, a coupling barrel, and a scroll spring. The fixing unit has a fixing portion disposed non-rotatably on the first side seat, and a spring-mounting portion extending oppositely to the fixing portion. The coupling barrel is disposed in and co-rotatable with the winding shaft, and is rotatable relative to the fixing unit. The scroll spring has opposite ends disposed respectively on the spring-mounting portion and the coupling barrel, such that rotation of the coupling barrel generates a resilient force for retracting the shade member.

A system for mounting a rollable screen, includes: a screen roll defining an end having a hollow tube; a coupling piece including: a neck element, having a sleeve adapted to be positioned in axial direction inside the tube. The contact surfaces included in the sleeve contact the tube, and recess surfaces in the sleeve define axial channels between the neck element and the tube; a transitional element fixedly connected to the neck element, one or multiple anchoring elements, adapted to fasten the neck element detachably to the tube. In an anchored state the anchoring elements are clamped inside the axial channels, with an even clamping along the axial direction.

Disclosed in the disclosure is a wind spring coiling apparatus with a wind spring built in an upper beam, including an upper beam and a bracket. A reel is mounted on the bracket. The coiling apparatus includes a wind spring, fixed discs and a coiling disc, the wind spring being sleeved on the fixed discs, and a coiling end of the wind spring being clamped with the coiling disc; and an adjusting plunger, one end of the adjusting plunger being in transmission connection with the coiling disc, and the other end of the adjusting plunger being connected with the reel through a transmission structure. By mounting a coiling apparatus in the prior art in an upper beam, the widths of a left bracket and a right bracket in the prior art can be greatly reduced, thereby being more suitable for blinds with narrower brackets and small face widths.

An architectural covering including a motor assembly is provided. The covering may include a head rail, an end cap enclosing an end of the head rail, a roller tube rotatably supported within the head rail at least partially by the end cap, and a motor assembly including a housing in splined engagement with the end cap to non-rotatably secure the motor assembly to the end cap. The motor assembly may be received at least partially within the roller tube and may be in driving engagement with the roller tube. A covering material may be attached to the roller tube such that rotation of the roller tube extends or retracts the covering material.
