摘要： A safety lift cord assembly for a window blind includes two ladder strings and multiple transverse strings located between the two ladder strings. The two ladder strings are parallel to each other, and the transverse strings control angular status of slats of the window blind. Two sleeves are located on two ends of the ladder unit. Two lift cords respectively extend through the two sleeves. The first end of each lift cord is fixed to a bottom rail, and the second end of each lift cord is connected to a roller in a top rail of the window blind. Two ropes respectively extend through the two sleeves. Multiple retainers are formed between the ladder strings and the ropes. When the lift cords are lifted, the ropes drive the ladder unit, and the sleeves are collected and is not dragged by the retainers to avoid from being torn or damaged.

摘要： A cordless window covering includes a first rail, a second rail, a covering body, two pulling cords, and a cord-retracting device including a first casing and an adjusting member movably disposed on the first casing. When relative motion of the first rail and the second rail occurs, the covering body is extended or retracted, and the two pulling cords apply a first force and a second force in opposite directions to the adjusting member respectively. When the first force does not equal to the second force, the user can exert slight force on the second rail to move the adjusting member towards a side with greater force, making one of the pulling cords applying greater force to the adjusting member have its length between the first rail and the second rail elongate as the adjusting member moves, such that the non-horizontal state of the second rail can be easily corrected.

摘要： A peak cover for lift cord and tilt ladder includes a limiter having an arcuate cover. A fixed engagement plate is disposed at an upper end of a left side of the arcuate cover. Two stop walls are disposed on two sides of a lower end of the left side of the arcuate cover. Two grooves are formed inside the stop walls. Two annular ribs of a cord winding reel are engaged in the grooves, whereby the cord winding reel is freely rotatable. A movable engagement plate is disposed at an upper end of a right side of the arcuate cover. Four raised columns are formed on an upper end of the arcuate cover. The arcuate cover of the limiter is capped on the cord winding reel. The fixed engagement plate and the movable engagement plate of the arcuate cover are engaged with the annular ribs on two sides of the cord winding reel. Accordingly, after the arcuate cover is connected with the cord winding reel, the arcuate cover blocks the space above the cord winding reel so as to prevent the cord wound on the cord winding reel from jumping out of the cord winding reel.

摘要： In one aspect, a leveling assembly for adjusting the levelness or skew angle of a bottom rail of a covering for an architectural structure includes at least one movable or slideable component configured to be moved or slid laterally relative to the bottom rail or a headrail of the covering to adjust the length(s) along which one or more of the lift cords extend within the bottom rail or headrail, which, in turn, adjusts the effective length of such lift cord(s) defined between the bottom rail and the headrail of the covering. Such adjustment of the effective length(s) of the lift cord(s) results in the horizontal orientation or skew angle of the bottom rail being varied, thereby allowing the levelness of the bottom rail to be adjusted, as desired.

摘要： A method for installing sunshade in light opening of building element is disclosed. The light opening comprises first and second edge surfaces. A glazing unit extends from the first edge surface to the second edge surface. The first and/or second edge surface is provided with at least two fastening holes. A fastener is installed in the fastening holes. Installation rail is attached to the fasteners which comprise a tip and a head part. Before the building element is mounted in the building, fastening holes are provided and the first ends of the fastening holes opening in the first and/or the second edge surface are closed. The first ends of fastening holes are opened in connection with installing fasteners. Fasteners are driven in fastening holes by inserting or screwing the tip part into the fastening hole, and the installation rails are attached to the head part remaining outside the fastening hole.

摘要： A screen device intended for a window or a door in a building or vehicle. The device includes a first elongated frame part having two ends; a further frame part and a third one, respectively, being arranged at each end of the first frame part at right angles to the first frame part and connected to a first one of its two ends. Two crossbars are arranged in parallel to the fixedly arranged first frame part and movable independently of each other along the two further frame parts. A pleated screen element is arranged between the first crossbar and the second crossbar, and the crossbars are guided by guide cords. At least one of the crossbars is formed by two profiles that are arranged in parallel to each other and leave a space between them in which a strip provided with holes for respective ones of the guide cords is received.
