Abstract
A horizontal window blind apparatus is disclosed for selectively controlling light transfer through a window. The apparatus includes a frame disposed within the window and a tab movably connected to and supported by the frame, the tab having a first and a second end. A slat has a front and a rear edge, the rear edge of the slat being connected to the first end of the tab such that the slat is cantilevered from the tab. A further tab is movably connected to and supported by the frame, the further tab having a first and a second extremity. Also, a further slat is disposed parallel relative to the slat, the further slat having a further front and a further rear edge. The further rear edge of the further slat is connected to the first extremity of the further tab such that the further slat is cantilevered from the further tab. The arrangement is such that in operation of the apparatus, when the tabs supported by the frame are moved, the slats cantilevered to the tabs are correspondingly moved for selectively controlling the light transfer through the window and for facilitating cleaning of the slats.
