Abstract: A single cord activation mechanism for collecting a window blind, especially a mechanism which uses a single cord to collect slats of a window blind, is primarily composed of a release shaft with a larger diameter which is connected coaxially with an activation shaft. The entire structure is located in a top rail longitudinally. The release shaft provides for winding a lifting cord for opening and closing the slats. The activation shaft provides for winding an activation cord through an arresting member. A linear length of releasing operation can be enlarged by increasing the diameter of activation shaft, and a height of operation can be safely and easily acquired according to opening and closing the slats with the single activation cord.

Abstract: A pull cord activation passage mechanism for a window blind, which is particularly used for providing a reaction length of a longer curvature in a passage of activating a pull cord for driving curtains of a horizontal blind, and for enabling the pull cord to enter into related sliding members in a nearly perpendicular direction, in order to enable an arresting member to be close to a first pull cord seat, comprises primarily a bending pulley located between a first and a second seats for providing a turning back of the first pull cord. An open ring is located on the seat, for providing sliding members to adjust corresponding to a pulling angle of the pull cord, thereby avoiding impedance in a slant direction, and enabling a smooth operation to the pull cord.
