A Venetian blind for day/night use includes a fixed upper beam attached at the top of a door/window, a movable beam disposed beneath the fixed upper beam, and a lower beam disposed at the bottommost thereof wherein a light-penetrable folding blind (slats) with cord passing holes disposed thereon is attached between the fixed upper beam and the movable beam thereof, and a sheltering folding blind (slats) with cord passing slots distributed thereon is located between the movable beam and the lower beam thereof. The fixed upper beam has three equally spaced cord passages arranged at the bottom side thereon in alignment with three through holes disposed at the upper surface of the movable beam thereon. A sheltering-blind pull cord unit and a light-penetrable-blind pull cord unit are respectively led through engaging holes with locating members mounted therein at both lateral sides of the fixed upper beam thereof and extend downwards till fixedly tied up to the movable beam and the lower beam respectively. Thus, the Venetian blind thereof is variably operated to display either the light-penetrable or sheltering blinds or both of them for day/night use to meet the need of a user according to different situations, and economically designed with both light-penetrable and sheltering blinds combined into one unit and sharing the same fixed upper beam, movable beam, and the lower beam, etc., to achieve the economical efficiency thereof.
A multi-functional shading device includes a first shading arrangement including a top traverse supporter adapted for affixing to a top beam of a ceiling, a first shading arrangement downwardly extended from the top traverse supporter including a base member and a first operating means for selectively lifting up the base member towards the traverse supporter and unlifting the base member to drop downwardly away from the traverse supporter, a second shading arrangement including a base stabilizer, a translucent fabric, which is folded in a Z-shaped manner, downwardly extended from the base member to the base stabilizer, a second operating means for folding and unfolding the translucent fabric, and a pair of windproof arms disposed on two sides of shading arrangements for restricting shading device from swaying back and forth. Therefore, the first and second shading arrangements having different light intensity blooding abilities are adapted for selectively blocking lights passing through from one side to another side of the shading arrangements respectively.
