Abstract: A light blocking system is disclosed, which is adapted to be used in a vertical blind which includes a headrail, a control mechanism provided in the headrail, and a covering assembly including a plurality of slats. Each of the slats is connected to the control mechanism with an end thereof, and therefore is hung below the headrail. A gap is left between the covering assembly and the headrail. The control mechanism is adapted to turn the slats in situ relative to the headrail, or to move the slats back and forth in a longitudinal direction of the headrail. The light blocking system includes a cover plate provided corresponding to the gap, wherein the cover plate covers the gap when the covering assembly is in a closed state.

Abstract: A light shielding structure for a vertical blind is disclosed, wherein the vertical blind includes a headrail and a plurality of slats, which are hanged under the headrail in a vertical manner, and can be controlled to be turned between a shielding position and a non-shielding position. The vertical blind includes at least one light shielding member, which is engaged to a bottom of the headrail, and can either be flipped up or naturally droop along with the turning of the slats. When the at least one light shielding member droops, gaps formed between the bottom of the headrail and a top of the slats are covered, which prevents light from leaking in therethrough.

Abstract: A locking mechanism is disclosed, which is installed in a movable rail of a window covering, and is passed through by a cord. The locking mechanism includes a locking unit and a pressing member, wherein the locking unit includes a stopping member which is movable between a first position and a second position. The stopping member is normally located at the first position to abut against the cord, which prevents the cord from moving relative to the locking mechanism, whereby to maintain the position of the movable rail. By pressing the pressing member, the stopping member is moved to the second position, where the stopping member no longer abuts against the cord. Therefore, when the movable rail is moved in a direction away from a fixed rail of the window covering, the cord can move relative to the locking mechanism. Whereby, the movable rail can be smoothly moved downward.
