ABSTRACT:
A louver holding carrier for vertical blind assemblies are slidably mounted within a track along which a rotably driving shaft passes through the carrier and imparting rotation to a worm gear assembly that in turn causes the sprocket termination of a louver holder to rotate. The sprocket termination has teeth over an arc of more than 90 degrees and less than 150 degrees in order to facilitate the jump of the meshed engagement between the worm gear assembly and the sprocket termination without jamming. A stopper member limits the rotation of the louver holding assembly.
