    Abstract: Each slat (3) is an oblong body with main body part (30) with convex top side (301) and concave underside (302). The main body part has front and rear longitudinal edges and is formed with through holes (33) next to the rear longitudinal edge through which the draw cord (45) is passed. The slat body has a front flange (32) which extends forwards from the front longitudinal edge, and a rear flange (31) which extends back from the rear longitudinal edge. The front flange of each slat is in close contact with the convex top side of the main body part of a lower adjoining slat so that a first light-screening section is obtained when the slats are closed. The rear flange stands upright and is behind an upper adjoining slat so that light from the back of the blind is screened off to produce a second light-screening section when the slats are in the closed position.

    Abstract: The elongated top housing (4) has an open underneath end (420). The top ends of vertical slats (20) are each connected to the horizontal shaft (5) mounted in the top housing for axially turning the shaft and slats on their vertical axes. The angle control (3) has a drive wheel (6) over which runs a slope-adjusting control chain (7) consisting of interconnecting beads (70). The slope-adjusting control cord has opposite free end sections (73) each of which has a thrust element (8) larger than the gap (c) between the drive wheel's periphery and the top housing, so as to prevent the cord from coming off the drive wheel. The periphery of the drive wheel may have an annular groove (62) containing the chain the beads of which detachably engage with the holes (63) containing the beads.
