ABSTRACT:
A vertical blind apparatus comprises a top track, a plurality of elongate vanes, and a carrier vane for independently, rotatably and slidably suspending each of the elongate vanes from the top track in side-by-side condition, such that the vanes may be rotated about a given arc relative to the track and also slidably drawn together or apart for opening and closing the blind, and for extending and retracting the blind relative to a window. Each vane carrier includes a resilient vane-receiving clip-like portion for releasably, grippingly engaging a top end portion of a corresponding vane and a glide for suspending the carriers from the track. Each of the vane carriers has oppositely outwardly extending lever arm portions aligned generally in parallel with the plane of the associated vane and generally in parallel with the plane of the associated vane and generally to either side of a vertical central axis thereof. A pair of elongate cords are operatively coupled to the lever arm portions for pivoting and sliding the vanes in unison.
