ABSTRACT:
An improved blind structure includes a Roman blind having a head-rail made up of a first and second engaging sections symmetrically extending at both top lateral sides thereof for a plurality of guide sliding seats to be respectively mounted thereto wherein a pull cord positioning seat and an actuation cord positioning seat are symmetrically joined at one end of the first and the second engaging sections thereof respectively, and a light-passable blind body is fixedly attached at the underside of the head-rail in alignment with the first engaging section thereof to be collected or expanded via pull cords. A plurality of black-out blind pieces are sequentially sewed in an equal space at one side of the light-passable blind body from top to bottom thereof, and at the bottom edges of the black-out blind pieces are detachably mounted a plurality of movable members that, each having a retaining through hole disposed thereon, are vertically lined up for actuation cords to sequentially thread there-through and tie up to each retaining through hole thereof respectively before winding around the actuation cord positioning seat to suspend downwards there-from. Therefore, the black-out blind pieces are raised upwards by the actuation cords towards one side of the head-rail to reveal the light-passable blind body in sections so that light can come partially indoors according to the position of the uplifted black-out blind pieces, efficiently boosting the function of the Roman blind thereof.
