Apparatus for adjusting the orientation of slats of a vertical blind

An apparatus for adjusting the orientation of slats of a vertical blind, comprising:

• a master slide and a plurality of carrier slides adapted to be slideably mounted on a headrail of the vertical blind, said master slide comprising:
• a housing;
• a driving member adapted to be connected with a control rod, rotatably mounted on the housing and defining a first gear, a worm member rotatably mounted in the housing and defining a second gear engaging with the first gear and a worm;
• and
• a helical gear rotatably mounted in the housing and engaging with the worm;
• a force transmission member engaging with the helical gear and extending from the master carrier to each of the carrier slides to transmit a rotating force from the driving member to the carrier slides;
• said carrier slides respectively comprising driven means each having an attaching member adapted to attach with a slat, the driven means being used to receive the rotating force from the force transmission member to cause a pivoting movement of the attaching members, the carrier slides having a first carrier slide fixedly attached with the master slide;
• and
• a plurality of strips respectively slideably engaging with the carrier slides, each strip having a first end defining a stop for blocking the movement of a respective carrier slide along the strip and a second end fixedly attached with a carrier slide neighboring the respective carrier slide slideably engaging with the strip.
