In one aspect, a covering for an architectural structure includes an upper rail, a bottom rail configured to be spaced apart from the upper rail, and an intermediate rail positioned between the upper rail and the bottom rail. The covering also includes a first shade panel supported between the upper rail and the intermediate rail that has a first shade configuration, and a second shade panel supported between the intermediate rail and the bottom rail that has a second shade configuration, with the second shade configuration differing from the first shade configuration.

A window covering includes a positional adjustment mechanism connected to a first rail that includes a spring motor unit, a first lift cord pulley connected to the spring motor unit, a first lift cord collection mechanism having a first roller positioned in the first rail, and a first lift cord that extends from the first lift cord pulley through window covering material such that a portion of the first lift cord passes along the first roller. The first roller is configured so that it only rotates a pre-selected number of revolutions when the window covering material is moved from the extended position to the retracted such that the first roller no longer rotates in the second rotational direction as the window covering material is moved from an extended position to a retracted position after having rotated the pre-selected number of revolutions in the second rotational direction.

A fabric venetian window shade assembly including: an actuation system for a double panel window shading including opposing first and second facings coupled by a plurality of vanes, the actuation system comprising: a roller configured to receive the opposing first and second facings; a ratcheting mechanism mechanically coupled to at least the second facing through the roller; and a grip coupled exclusively to a lower end of the second facing, wherein, in response to a downward force being applied to the grip, the downward force is applied directly to the second facing without being applied directly to the first facing, and wherein the ratcheting mechanism is further configured to adjust a position of the opposing first and second facings and an orientation of the plurality of vanes relative to the opposing first and second facings.

A cordless shade roller is revealed. The cordless shade roller includes a roller tube, a passive-end bracket set on a first end of the roller tube, and an active-end bracket disposed on a second end of the roller tube. The active-end bracket is a cap formed by assembly of a first cover with a second cover and having a narrow space therein. An S-shaped constant force spring is clipped in the narrow space of the cap. The S-shaped constant force spring consists of a first wound roll used as a storage drum, a second wound roll used as an output drum, and an S-shaped spring strip wound around the first wound roll and the second wound roll reversibly. No baffle is disposed on each of two sides of the first wound roll and of the second wound roll.

A locking mechanism is disclosed, which is installed in a movable rail of a window covering, and is passed through by a cord. The locking mechanism includes a locking unit and a pressing member, wherein the locking unit includes a stopping member which is movable between a first position and a second position. The stopping member is normally located at the first position to abut against the cord, which prevents the cord from moving relative to the locking mechanism, whereby to maintain the position of the movable rail. By pressing the pressing member, the stopping member is moved to the second position, where the stopping member no longer abuts against the cord. Therefore, when the movable rail is moved in a direction away from a fixed rail of the window covering, the cord can move relative to the locking mechanism. Whereby, the movable rail can be smoothly moved downward.

A motorized shade for covering an architectural opening comprising a roller tube and a shade material comprising an upper end attached to the roller tube and a lower end. The shade material at least partially comprises electrically conductive material and the roller tube comprises an electrically conductive material that creates an electrically conductive path between the conductive material of the shade material and the roller tube. The motorized shade further comprises a capacitive touch sensor electrically connected to the roller tube via at least one electrical contact, and a controller electrically connected to the capacitive touch sensor and adapted to detect a touch of the shade material via the capacitive touch sensor and in response generate a command.

In one aspect, a cordless covering may include a roller and a shade panel configured to be wound around and unwound from the roller to move the shade panel between an extended position and a retracted position. The shade panel may include a front panel, a back panel, and a plurality of vanes extending between the front and back panels. The covering may also include a roller shaft extending through the roller and a tilt adjustment mechanism coupled to the roller shaft. The tilt adjustment mechanism may be configured to rotate the roller shaft to adjust a tilt angle of the vanes between an opened position and a closed position.

A spring drive system for a window shade includes a housing, a first and a second gear engaged with each other and respectively assembled about a first and a second pivot axis, two springs respectively assembled at two opposite sides of the second gear and respectively connected with two take-up reels provided on the first gear, a first cord drum and a third gear fixedly connected with each other and assembled about a third pivot axis, the first and third gears being respectively located at different levels along the first and third pivot axes and respectively engaged with a first gear train, a second cord drum and a fourth gear fixedly connected with each other and assembled about a fourth pivot axis, the second and fourth gears being respectively located at different levels along the second and fourth pivot axes and respectively engaged with a second gear train.

A window blind includes an upper beam, a plurality of foldable slats, a lower beam, a fastener, a spring, a movable base, a fixed base, a first wheel set, a second wheel set, and a third wheel set. The upper beam includes a lower part and a slideway. The plurality of foldable slats is fastened to the lower part of the upper beam and includes a lower part. The lower beam is fastened to the lower part of the plurality of foldable slats. The fastener, the spring, the movable base, and the fixed base are disposed between the upper beam and the plurality of foldable slats. The fastener and the fixed base are fixed on the upper beam. The movable base is disposed in the slideway. The spring includes two ends. The fastener includes a first hook and the movable base includes a second hook.

A slat device (1) comprising a plurality of slats (2) arranged parallel to one another, displacement means (9, 10) for displacing the slats (2) between and in a stacking zone and a sliding, and a guide profile (3), which is arranged on a lateral side of the slats (2), wherein a slat (2), on the said lateral side, is provided with a guide element (5), corresponding with the guide profile (3), for guiding the respective slat (2) relative to the corresponding guide profile (3, 6) during its displacement motion between and in the stacking zone and the sliding zone, such that the guide element (5) is rotatable over a certain angle relative to the guide profile (3) about an axis according to the longitudinal direction of the guide profile (3).
