THIS invention relates to a slat for a blind and a blind formed from such slats. More specifically, the invention relates to a customisable rigid slat, or blind made up of a plurality of such customisable rigid slats, that enables the blind to be fitted snugly within any window opening or doorway as a result of the locking adjustability of the width of such slats. The slat includes a pair of elongate slat panels movable relative to one another between retracted and extended conditions, such that the operatively width of the slat is greater in the extended condition than in the retracted condition. The slat further includes one or more fasteners, located at or near each of a pair of minor ends of the slat panels, for releasably fixing the pair of slat panels to one another in the retracted condition, the extended condition and/or any condition there between, thereby to operatively restrict relative movement between the slat panels in such condition.

A control rope guide device for a window curtain assembly includes a bottom part and a top part. The top part is connected to the top of the bottom part. The control rope guide device is cooperated with the window curtain assembly to separate two control ropes apart from each other so as to smoothly expand or lift the curtain.

A linkage rod including a limited-displacement flexible mechanism has structural robustness and allows easy reduction in weight and size, simple production and easy operation. The linkage rod including at least one limited-displacement flexible mechanism, wherein the limited-displacement flexible mechanism comprises at least one limited-displacement flexible joint which comprises: a flexible member; and at least one bend limitation section which is arranged in parallel with the flexible member so that the bend limitation section limits a bend of the flexible member.

We disclose a cordless window covering that may raise, lower, and tilt a plurality of slats without the use of lift cords. The covering may include an external frame with two vertical sides and a headrail. The covering may also include a plurality of slats, each of which may be connected to an adjacent slat by at least one string on each side and the headrail. This may allow the slats to hang freely when lowered. It may also allow all the slats to tilt when only the top slat has been mechanically tilted by a drive belt. The bottom slat may include a bottom bearing connector which may interact with a drive belt such that it may be raised and lowered when the drive belt rotates. Each slat may be connected to a bearing and a bearing connector that may be slidably connected to a guide channel.

We disclose a cordless window blind that includes at least one electromagnet within each slat. The slats may be inserted into orifices within rotatable slat mounting members on a vertical guide rail assembly. The orifices may house electrical connections which connect the electromagnets to at least one battery. The electromagnets may have the same polarity such that the electromagnet of one slat attracts the electromagnet of an adjacent slat. The magnetic attraction may move one slat toward the other slat causing the slats to move vertically along the guide rail assembly and either raise or lower the blinds. Alternatively, electromagnets on only one of two longitudinal edges of the slats may be actuated and attract a metal member on an adjacent slat. The magnetic attraction may cause the slats to tilt and rotate within the slat mounting members thus closing the blinds.

A nut stacking mechanism (-1-) for the displacement of slats between a stacking zone (L2) and a sliding zone (L1), comprising a spindle (2), on which a nut (3) is displaceable between the stacking zone (L2) and the sliding zone (L1), a rotation stop element (4), to form in the sliding zone (L1), in the rotational direction of the spindle (2), an obstacle for the movement of the nut (3), and a stacking element (5), to form in the stacking zone (L2), in the longitudinal direction of the spindle (2), an obstacle for the movement of the nut (3), wherein, by displacement of at least a part of the rotation stop element (4) and the stacking element (5), the boundary between the stacking zone (L2) and the sliding zone (L1) is provided displaceably in the longitudinal direction of the spindle (2).

A shading device for being arranged in association to a window includes an elongated guide rail arrangement that is adapted to be stationarily arranged relative to the window, an extendable covering, at least one elongated support member and a movement arrangement. The extendable covering is supported by the at least one elongated support member, wherein the at least one elongated support member is arranged to extend with its longitudinal direction in a transverse orientation relative to a longitudinal direction of the elongated guide rail arrangement and arranged to be movable along the elongated guide rail arrangement in the transverse orientation by the movement arrangement so that the extendable covering may be moved between a retracted state and an extended state for covering the window to different extents.
