Abstract

1535518 Vertical slat blind H GROSS 24 Dec 1975 [31 Dec 1974] 52797/75 Heading E1J [Also in Division F2] A drive mechanism for a vertical slat blind incorporates a lost-motion arrangement so that the slats turn before they move laterally on opening or closing the blind; the lost motion device comprises an epicyclic gearing arrangement with a sun wheel 14 on the drive shaft 12 (driven from the main shaft 4), two planet wheels 16 with projecting stops 17 and an annulus 15 with stops 18 connected to the output shaft 7 driving the transport mechanism; output shaft 6 driving the slat turning mechanism is driven by shaft 4, slipping clutches are incorporated in each drive mechanism. When the drive shaft 4 is rotated shaft 6 immediately operates the slat turning mechanism, the planet wheels 16 rotate within the annulus until the stops 17, 18 abut when the annulus rotates with the shaft 12.
