Blind structure

An improved blind structure, including a Roman blind made up of a light-passable blind body fixedly attached to one side at the bottom of a head-rail to be actuated by pull cords, and a plurality of black-out pieces sequentially fixed in an equal space at one side of the light-passable blind body from top to bottom thereof wherein at the bottom edges of the black-out blind pieces are respectively equipped with two or more than two 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;

• a plurality of guide sliding seats are properly mounted at both top lateral sides of the head-rail respectively, and a pull cord positioning seat and an actuation cord positioning seat are symmetrically jointed at one end of the head-rail for the pull cords and the actuation cords led through the guide sliding seats disposed at both lateral sides of the head-rail to wind around respectively before hanging downwards there-from to suspend symmetrically at the front and rear sides of the light-passable blind body thereof;
• in practical use when the black-out blind pieces are raised upwards by the actuation cords towards one side of the head-rail, the light-passable blind body will be revealed in sections through the uplifted black-out blind pieces, permitting light to come partially indoors according to the position of the raised black-out blind pieces, or views outside to be easily seen there-through;
• thus, the Roman blind can not only be completely collected or expanded in a total black-out status, but can also be synchronically adjusted to provide partial light and partial black-out effects;
• besides, via the number of the actuation cords drawn upwards and the movable members or the guide sliding seats detachably mounted and freely adjusted in positions, the black-out blind pieces can be flexibly lifted upwards in any angles, permitting the light-passable blind body to reveal versatile perspective spaces accordingly and facilitating a variable operation of the Roman blind to fit to the needs of different users.
