A window blind includes a control structure and an adjusting member. The control structure is adapted to move a bottom rail relative to a headrail, whereby to lower and raise the window blind. The adjusting member is adapted to move ladders to tilt the slats, allowing a different amount of light to travel through the window blind. Particularly, the adjusting member provides a two-step adjusting function. Whereby, the window blind could provide a good shielding effect when the window blind is completely lowered.

A multi-partition blind system include a system of mechanisms that cause slats on a covering for an architectural opening to be partitioned into multiple operational sections. Partitions may be created to the extent of controlling each individual slat. Various embodiments and mechanisms are used to control, stabilize, and cause the opening and closing movement of one group of partitioned slats independent of others or individual slats independent of others.

A skew adjustment mechanism is used for adjusting the length of a lift cord on a window covering. The lift cord extends from a lift spool at a first end to an anchor drum at a second end. A cord wrap post is provided between the lift spool and the anchor drum so that the lift cord can be wrapped around the cord wrap post to provide friction between the lift cord and the cord wrap post when the lift cord is taut in order to reduce the amount of holding force that is needed to prevent the anchor drum from rotating.

A window blind assembly is disclosed and comprises a blind set, a light modulation device, a pull cord take-up device, and a coil spring control device. The blind set includes a bottom rail, a stopper, leaves, a blind ladder, pull cords, and a headrail. The light modulation device includes a wheel set, a wheel, a cover, an iron bar, a block, and a stick. The pull cord take-up device includes two mounts, a wrapping reel, and iron cores. The coil spring control device includes a bottom plate, a driving gear, a spring shaft, a coil spring, an upper gear cap, an upper cap, and a driven gear. The angle adjustment of the leaves of the blind set is realized by rotating the wrapping reel. When the bottom rail is pulled downwardly, the pull cords are driving the wrapping reel to rotate. The pull cord arranged on the coil spring control device is pulled out and wrapped around the wrapping reel. When the bottom rail is pulled upwardly, the pull cords is taken up in the coil spring control device and wrapped around the wrapping reel. It has the advantages of simplified structure, safety, and reliability, especially suitable for using in house.
