A covering for an architectural feature having generally horizontal vane elements coupled to and located between generally front and rear generally vertical support members, which in preferred embodiments are adjustable to control the amount of light transmitted through the covering. In one embodiment the covering has three dimensional multi-layered, cellular vanes, and in another embodiment, the one or more support members are formed of a dark color, and the rear support member(s) may be formed of material that is darker than the front support member(s), or vise versa. In another embodiment, the support members, e.g., sheers, have an openness factor, preferably as low as about sixty-five percent (65%) to as large as about ninety percent (90%). Other embodiments include structure, assemblies and methods for controlling the closure of the covering as well as embodiments of bottom rail assemblies. Also provided is a method of manufacturing the covering.

A window covering apparatus is disclosed, along with a method of using the same. The apparatus may include an upper board component and a lower board component, which are releasably held by central mounts. The upper board and lower board components can be arranged in a fully open shutter state, a half open shutter state, or a fully closed shutter state. The central mounts are positioned near flush to one or more outside or surrounding window surfaces in order to block light transmission. In one embodiment, the upper board and/or the lower board component may incorporate decorative elements and a gapless seam between the upper board and lower board components.

The invention relates to a screen, comprising a first control unit (610) comprising a first drive shaft (612) and at least one first cord spool (630) rotatable with the first drive shaft for winding and unwinding a first lift cord (634) extending between a head rail and a middle rail; a second control unit (620) comprising a second drive shaft (622), and at least one second cord spool (632) rotatable with the second drive shaft for winding and unwinding a second lift cord (636) extending between the head rail and the bottom rail; and a shaft rotation limiting system (100) comprising a threaded shaft arranged on and rotatable in unison with one of the first and the second drive shafts, a coupling element threaded on said threaded shaft, wherein the coupling element is associated with and rotatable in unison with the other drive shaft.

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.

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.

A smart transformable shading system with adaptability to expand and retract in response to solar radiation comprises, in one implementation, a housing unit, a plurality of structural cells, and a plurality of modular units. The structural cells are within the housing unit, and are aligned in first and directions with respect to the housing unit. Each modular unit is placed within a corresponding structural cell, and includes a plurality of structural rings, a plurality of deployable shell panels, a plurality of control units, and a plurality of circuit units. Each circuit unit is connected to a corresponding control unit, which in turn is connected to a corresponding deployable shell panel, the combination of which is placed within a corresponding structural ring to transform into different geometries in response to light.

A portable sunshade assembly comprising: an in-use top flexible sheet spaced away from an in-use bottom flexible sheet wherein during use in an extended configuration the top and bottom flexible sheets comprise respective surfaces and are arranged to define a space there-between to provide a plurality of passages located between the first and second sheets to allow air to pass in a direction from a first side of the top and bottom flexible sheets to a second side of the top and bottom flexible sheets.

A curtain may include a blind shade stretched or contracted in a first direction to adjust transmittance of light, a base coupled to one end portion of the blind shade in the first direction thereof, and a transmittance adjusting device to adjust the transmittance of the light passing through the blind shade by pulling outward or releasing inward an other end portion of the blind shade in the first direction thereof, in the state that spacing from the base in the first direction is fixed.

A covering for an architectural covering is provided. The covering may include a rotatable outer tube, a rotatable inner tube, a shade attached to the outer tube, and an operating element secured to the inner tube. The outer tube may define an elongated slot extending along a length of the outer tube and opening to an interior of the outer tube. The inner tube may be received within the outer tube. The shade may be retractable to and extendable from the outer tube. The operating element may extend through the elongated slot and may be retractable onto and extendable from the inner tube. The inner tube may rotate relative the outer tube to open and close the shade once the support sheet is in a fully extended position.

A motorized window treatment system is provided for moving a covering material (e.g., a shade fabric). The motorized window treatment system includes a motor drive circuit configured to generate signals that cause a motor to change a position of the covering material. A sensor circuit is provided to generate one or more sensor signals indicative of the position of the covering material. The motorized window treatment system further includes a control circuit coupled to the sensor circuit to receive the one or more sensor signals. The control circuit is configured to detect a power-down event when a supply voltage is equal to or less than a threshold value, and stores a power-down position and one or more power-down sensor states. The control circuit is configured to determine a present position based on the stored power-down position and the one or more power-down sensor states.
