Abstract: A window blind includes a headrail, two lift cords, a blind body, a bottom rail and two cord winding devices. The two cord winding devices are respectively installed on the bottom of the bottom rail. Subject to the technical feature that the opposite ends of the two lift cords are respectively tied to the adjustment columns of the two cord winding devices, if the winding stroke is inconsistent and the blind body is folded unevenly or skewed when the window blind is folded or stretched, the adjustment column of one cord winding device can be fine-adjusted to let the respective lift cord be gradually wound and covered on the adjustment column, so that the bottom rail and the blind body can be gradually adjusted to be substantially parallel to the bottom of the headrail, thereby effectively achieving the effect of fine-tuning and correcting the blind body.

Abstract: A cord divider is positioned on both sides of the cord winder of the control box of a cordless window curtain. Each cord divider is equipped with protrusions and crosspieces. When the cords are pulled out from the cord divider, the cords do not tangle or knot. The cords are wound up on the driving gear set, and the driving cord device prevents the cords from overlapping and causing uneven heights on both sides of the curtain. The use of cylinders in the cord dividers prevents excessive friction of the cords during use. There is no need to change the current cooperation way between the cords and the cord winder.

Abstract: A method for forming a honeycomb curtain and includes a weaving process, a fixing process, a gluing process, a stacking process and a cutting process. The honeycomb curtain includes multiple netted tubes, and each netted tube includes an upper portion and a lower portion. The central portion of each of the upper and lower portions is woven to form a tight-woven structure. Two sides of each of the central portions are woven to form a sparse-woven structure to form the upper portion to be a breathable first semi-transparent strip and to form the lower portion to be a second semi-transparent strip. The outer corner of each of the upper and lower portions are woven to form another tight-woven structure. The central portions of each of the netted tubes are applied with glue on respective outer face thereof. The netted tubes are stacked and pressed to form a layered structure.

Abstract: A window blind includes a headrail, two lift cords, a blind body, a bottom rail and two cord winding devices. The two cord winding devices are respectively installed on the bottom of the bottom rail. Subject to the technical feature that the other ends of the two lift cords are respectively tied to the adjustment columns of the two cord winding devices, if the winding stroke is inconsistent and the blind body is folded unevenly or skewed when the window blind is folded or stretched, the adjustment column of one cord winding device can be fine-adjusted to let the respective lift cord be gradually wound and covered on the adjustment column, so that the bottom rail and the blind body can be gradually adjusted to be substantially parallel to the bottom of the headrail, thereby effectively achieving the effect of fine-tuning and correcting the blind body.

Abstract: A window blind includes a headrail, a blind body, two ladder tape assemblies and a bottom rail. By the technical features that the lift cords of the ladder tape assemblies are set in the mesh webbings, any one of the slats is surrounded by the supporting cords of the ladder tape assemblies arranged opposite to each other, and the two ends of the supporting cords are respectively braided and connected to the mesh webbings of the two ladder tape assemblies arranged opposite to each other, in addition to the effect of stabilizing the support between any of the slats, it can also reduce the possibility of the lift cords of the ladder tape assemblies being pulled out, thereby effectively preventing children from being accidentally entangled by the lift cords.

Abstract: A window blind includes a headrail, two lift cords, a blind body, a bottom rail, and two cord winding assemblies that are respectively installed on two opposite sides of the long axis of the bottom rail. The other ends of the lift cords are respectively tied to respective adjustment columns of the cord winding assemblies. When the window blind is folded or stretched, unfortunately, when the winding stroke is inconsistent, the blind body is not folded uniformly or skewed, and the adjustment column of the cord winding assembly on one side can be finely adjusted, so that one of the lift cords is gradually wound and covered on the adjustment column, and indirectly drives the bottom rail and the blind body to gradually adjust to substantially parallel to the bottom of the headrail, thereby effectively achieving the effect of fine-tuning and correcting the blind body.

Abstract: A window blind includes a headrail, a control device mounted in the headrail, a rotating rod, a blind body, a bottom rail, two lift cords, and two cord winding assemblies mounted on the rotating rod. Subject to the technical feature that the lift cords have the respective one ends thereof connected to the sliding guides of the respective cord winding assemblies and the respective other ends thereof extending along the respective lead angle sections of the respective openings of the respective rotating members and connected to the respective cord insertion holes of the headrail, when the blind body is in the unfolded or folded state, the clamping force produced on the lift cords between the sliding guides and the openings of the respective rotating members can be reduced, preventing the lift cords from being pushed down to break, which greatly increases the service life of the window blind.
