Abstract (en)
[origin: WO8905603A1] A winding shaft (2) is driven by a bead chain (10) and is connected to winding rollers (3) via worm gears (4, 5). Each winding roller (3) is intergral with a worm wheel (4) rotatably mounted in a housing (13). When the tableau curtain is mounted, the axes of the worm wheels (4) are arranged horizontally and perpendicular to the winding shaft (2). The transmission ratio of the worm gear (4, 5) is chosen so that the lift is self-locking. A separate braking device is not required. The tableau curtain is particularly suited for sloping windows, as well as for tall windows and heavy curtain materials.
