ABSTRACT:
An apparatus for adjusting the orientation of slats of a vertical blind includes a master slide and a first carrier slide fixedly connected with the master slide and a plurality of other carrier slides. The master slide includes a housing, a driving member, a worm member and a helical gear engaging with the worm member. When the driving member rotates, the helical gear rotates accordingly. A shaft is extended to engage with the helical gear and driven mechanisms provided respectively in the carrier slides. Each driven mechanism is attached with a slat. When the helical gear is rotated, the slats attached with the driven mechanism rotate accordingly so that the orientation of the slats can be adjusted. Each of the carrier slides is slideably engaged with a strip which has an end defining a stop and another end fixedly attached with a carrier slide neighboring the carrier slide slideably engaging with a respective strip.
