Disclosed is a roman shade assembly that utilizes lift bands rather than lift cords. The shade can be formed of textured materials or woven woods. The shade assembly includes lift bands that attach to a rotatable member(s) and can be extended or retracted within an architectural opening by rotating the member(s). The lift bands can be slidingly connected to the shade at multiple points along the vertical length of the shade. Accordingly, as the wide lift bands are extended or retracted, the attached shade is likewise extended or retracted to cover or uncover an architectural opening.

Methods and apparatus to control architectural opening covering assemblies are disclosed herein. An architectural covering assembly including an architectural covering; a tube to which the architectural covering is coupled; a manual controller operatively coupled to the tube to rotate the tube; a motor including a motor housing and a motor shaft; and a clutch assembly including a clutch and a clutch housing in which the clutch is disposed, the motor shaft coupled to the clutch and the clutch coupled to the manual controller to hold the motor shaft substantially stationary when the architectural covering is moved under an influence of the motor to cause the motor housing to rotate with the clutch housing and the tube.

A blind lifting control module includes a transmitting wheel, an anti-backward unit and a driving unit disposed to a supporting unit. The transmitting wheel for connecting a blind reeled horizontal axle has a wheel ratchet portion meshable with a corresponding reel ratchet portion of a driving reel of the driving unit. The anti-backward unit has a torsion spring operable and deformable relative to the transmitting wheel. A pull cord is reeled on the driving reel and has a free end passing through a thrust member and a hindering member, and is pulled to shift the torsion spring to a released state to permit lowering of a blind. The thrust member is turned by pulling of the pull cord to thrust the driving reel to mesh with the transmitting wheel for lifting the blind.

A curtain controller structure is disclosed herein. It comprises a fixing seat, an assembling seat having an accommodation space formed between the fixing seat and the assembling seat and a first chamber, a bead chain disc disposed in the accommodation space, a first driving assembly disposed in the first chamber of the assembling seat and having a first driving unit and a second driving unit, and a traction string connected to the first driving unit or the second driving unit of the first driving assembly and the bead chain disc.

The geared window shade bracket comprises a sprocket having a ring gear on an inside circumference of the sprocket; a chain configured to be engaged with the sprocket such that, in response to pulling on the chain, the sprocket rotates; a sun gear that is configured to be restricted from rotation; one or more planet gears configured to rotate around the sun gear, wherein the one or more planet gears interface with the ring gear; and a planetary carrier configured to mate with the one or more planet gears. In response to the chain being pulled, the sprocket rotates, causing the planet gears to rotate, causing the planetary carrier to rotate, causing the hub to rotate, and causing a shade tube to rotate.

A wand for a blind assembly comprising (a) an elongated member, (b) a rotatable member located at or adjacent one end thereof, (c) guide member located at or adjacent another end thereof; and (d) a cord having a loop, wherein the loop passes from a position remote from the rotating member, engages the rotating member, passes about the guide member and returns to the remote position after reengagement of the rotating member, wherein the loop adjacent to or within the elongated member is retained between the rotating member and the guide to restrict movement of the loop perpendicularly of the elongated member, and wherein the loop remote from the rotating member is adapted to engage and rotate a drive member of a blind assembly.

A manually-operated window treatment system may include a roller tube, a covering material, and a semi-rigid chain assembly. The covering material may be attached to the roller tube and may be operable between a raised position and a lowered position via rotation of the roller tube. The semi-rigid chain assembly may be configured to be operated by a user to rotate the roller tube. The semi-rigid chain assembly may be configured to limit the size of a loop that can be formed by the semi-rigid chain assembly. The semi-rigid chain assembly may be operatively coupled to a drive pulley of the window treatment system. The semi-rigid chain assembly may include flexible outer housing and a stiffening rod. The flexible housing may surround and operate along the stiffening rod. The hollow chain may include multiple links that are connected together to form a continuous loop.

A set of blinds or other window coverings can be made more safe by keeping the pull string out of reach of infants or young children. A safety disc can be secured to the pull string while a safety anchor is secured to a window frame, a door frame, a wall surface near the window covering, or other similar surface. The safety disc and safety anchor are adapted to be removably attaching to one another. In one embodiment, the safety disc and safety anchor each comprise a hook-and-loop attachment surface. In one embodiment, magnets and/or magnetic surfaces are utilized to removably attach the safety disc and safety anchor to each other. In one embodiment, the safety disc comprises a suction cup attachable to a window.

A curtain controller for easily assembling a bead chain thereof is provided. A bead chain turntable is disposed on an assembling terminal surface of a fixing seat. A positioning seat is combined with the fixing seat to clamp and position the bead chain turntable. A protective cover is assembled on an outer side of the positioning seat. A shielding part is disposed at one side of the protective cover to correspond to an upper edge of the assembling terminal surface of the fixing seat. A fastening groove is disposed at an outer edge of the assembling terminal surface of the fixing seat. A fastening flange is disposed on the shielding part of the protective cover to be inserted into and combined with the fastening groove. A ladder section is formed between a lower side of the fastening flange and the shielding part.

The invention refers to a pull cord arrangement for a roller blind or a venetian blind, comprising a winding element (4) arranged to be connected to a blind (6) such that the blind (6) is released or wound in response to a rotational movement of the winding element (4) about a rotational axis; a connecting element (28) coupled to the winding element (4) to rotate together with the winding element (4); and a pull cord (50) engaging the connecting element (28) so as to control the rotation of the connecting element (28) and thus the winding element (4) as the pull cord (50) is operated.
