    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 pull-cord control device for a curtain without an operation cord includes a pull-cord (3), a base (1), and a pressing plate (2) rotatably mounted to the base through a rotation shaft (42). The base forms first friction shafts (11). The pressing plate forms second friction shafts (21) staggered with the first friction shafts. The pressing plate forms a fixing pole (41). A first end of the pull-cord is connected to a retractable-cord device (5), and a second end of the pull-cord extends between the first and second friction shafts, and is connected to a curtain body (6) after extending about the fixing pole. When the curtain body moves up and down, the pressing plate is rotated between a clamping position and a loose position. When the pressing plate is in the clamping portion, the second friction shafts actuate the pull-cord to wander between the first and second friction shafts.

    Abstract: A window covering includes a first rail and a plurality of non-moving elements arranged adjacent at least one spring motor positioned in the first rail. The non-moving elements contact at least one lift cord for routing of the lift cord through the first rail to increase friction incurred during motion of the lift cord(s) that takes place during height adjustment of window covering material. Non-moving members can also be positioned to contact at least one lift cord for routing of the lift cord through the first rail to increase friction incurred during motion of the lift cord(s) that takes place during height adjustment of window covering material. The non-moving elements and non-moving members can be positioned in the first rail such that they do not move relative to the first rail when the window covering is mounted and installed for use by a user to adjustably cover a window.

    Abstract: A retaining device for an operating member of a window shade includes a casing having an opening, a sliding part having a first and a second inner cavity, and a spring respectively connected with the sliding part and the casing. The sliding part is assembled with the casing, and is movable between a first and a second position, wherein the sliding part in the first position occludes the opening and has the first inner cavity exposed for insertion of an operating member of a window shade, and the sliding part in the second position has the first inner cavity retracted toward an interior of the casing while the second inner cavity overlaps with the opening for facilitating travel of an operating member of a window shade through the opening and the second inner cavity. The spring is operable to urge the sliding part to move toward the first position.

    Abstract: A window body brake mechanism for non pull cord window blind includes two one-way clutch units for controlling the movement of two transmission cords respectively. The one-way clutch unit includes a wheel axle holder, a clutch wheel axle fixedly mounted in the wheel axle holder and having a plurality of brake blocks equiangularly spaced around one end thereof and a rolling groove defined between each two adjacent brake blocks, a clutch wheel rotatably mounted on the clutch wheel axle and having an internal gear located therein around the brake blocks, and a plurality of planetary gears rotatably mounted in one respective rolling groove and meshed with the internal gear of the clutch wheel. Thus, the planetary gears are drivable by the internal gear of the clutch wheel into engagement with the respective brake blocks of the clutch wheel axle or away therefrom.
