SAFETY LIFT CORD ASSEMBLY FOR WINDOW BLINDS
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.
