A fastener overlay assembly at an interface between first and second curtain segments of a rolling smoke/fire curtain positioned at an opening in a structure, the curtain segments having leading edges affixed to a bottom bar and extend between opened and closed positions by winding on a barrel assembly, each curtain segment connectable to the other curtain segment by a fastener during unwinding. The overlay assembly has an overlay strip with a leading edge proximate a leading edge of the curtain segment(s); and a retractable overlay collector roller attached to a first end of the overlay strip and configured to allow the overlay strip to unwind from a collector roller synchronously with the winding and unwinding of the curtain segments, wherein the retractable fastener overlay strip is arranged, in its extended position, in front of or behind the fastener that connects the first and second curtain segments.

A covering for an architectural covering is provided. The covering may include a rotatable outer roller, a rotatable inner roller, a first shade secured to the outer roller, and a second shade secured to the inner roller. The outer roller may define an elongated slot extending along a length of the outer roller and opening to an interior of the outer roller. The inner roller may be received within the outer roller and may define a central longitudinal axis. The first shade may be retractable onto and extendable from the outer roller. The second shade may extend through the elongated slot and may be retractable onto and extendable from the inner roller. The elongated slot may be substantially horizontally aligned with the central longitudinal axis of the inner roller when the first shade is in a fully extended position.

Example motor assemblies for architectural coverings are described herein. An example architectural covering assembly includes an architectural covering movable between an upper limit position, a lower limit position, and a transition limit position between the upper limit position and the lower limit position. The example architectural covering assembly also includes a motor, a consumer touchpoint, and an architectural covering controller. In response to detecting a first gesture at the consumer touchpoint, the architectural covering controller is to activate the motor to move the architectural covering to the transition limit position and stop, and in response to detecting a second gesture at the consumer touchpoint, different from the first gesture, the architectural covering controller is to activate the motor to move the architectural covering through the transition limit position and to the upper limit position or the lower limit position.

The present disclosure relates to a roller clutch assembly. The roller clutch assembly includes a beaded chain wheel having an inner radial surface, a drive adapter having a base and an internal channel, the base including a support surface configured to retain the driver adapter along the inner radial surface of the beaded chain wheel, a support shaft configured to extend through the internal channel of the drive adapter, a main shaft positioned around the support shaft, the main shaft having an inner radial surface and an outer radial surface, at least a portion of the outer radial surface being tooled, and a spring positioned around the main shaft, the spring abutting at least a portion of the tooled portion of the outer radial surface. The system also includes at least one pulley for guiding the beaded chain of the roller clutch assembly.

A covering for an architectural covering is provided. The covering may include a rotatable outer roller, a rotatable inner roller, a first shade secured to the outer roller, and a second shade secured to the inner roller. The outer roller may define an elongated slot extending along a length of the outer roller and opening to an interior of the outer roller. The inner roller may be received within the outer roller and may define a central longitudinal axis. The first shade may be retractable onto and extendable from the outer roller. The second shade may extend through the elongated slot and may be retractable onto and extendable from the inner roller. The elongated slot may be substantially horizontally aligned with the central longitudinal axis of the inner roller when the first shade is in a fully extended position.

An alignment bracket for a roller blind, comprising a base and a roller tube support securable to the base. First and second coupling members on the base and roller tube support permit an adjustment of the alignment of the roller tube support, and the end of a roller tube mounted thereon, relative to the base. Also provided is a blind fabric alignment device for a roller tube of a multi-tube roller blind. The alignment device comprises a drive coupling body securable to an end of a roller tube of the blind, a driven member mounted to the drive coupling body, a torque transfer mechanism secured to the driven member, and an adjuster. The torque transfer mechanism transfers rotational torque from the driven member to the drive coupling body through the adjuster. The adjuster permits an alteration of the rotational position of the driven member relative to the drive coupling body.

A driving mechanism for a roll blind capable of shade adjustment is proposed. The driving mechanism includes: a cover housing (212) having a stopper (212c) protrudingly foamed; a driving shaft (213a) relatively and rotatably coupled to the cover housing (212); a torsional coil spring (220) wound and tightened around an outer circumferential surface of the driving shaft (213a); and a clutch wheel (223) integrally rotating with the driving shaft (213a), wherein, in a case when the torsional coil spring (220) is caught by the stopper (212c) while the driving shaft (213a) is rotating, rotation of the torsional coil spring (220) is blocked therethrough, whereas the driving shaft (213a) is continuously rotatable regardless of whether the rotation of the torsional coil spring (220) is blocked, and wherein the driving mechanism further includes a tilting gear (222) and a tilting wheel (224) rotated in conjunction with the tilting gear (222).

A retractable covering for an architectural opening includes a headrail in which a control system is mounted and a fabric suspended from the headrail. The fabric is mounted to be moved laterally between a rolled up retracted position and an extended position across the architectural opening. At least one roller about which the fabric can be wrapped is mounted at an end of the headrail for rotation about a vertical axis, and the system includes a flexible control element that is substantially horizontally disposed for moving the covering between extended and retracted positions.

A skylight assembly in which the skylight, passing sunlight from a building's exterior to an interior of a building, has a translucent flexible membrane selectively extending across the skylight and having at least one graphical image imprinted on the flexible membrane.
