Abstract
An arch-shaped window blind assembly that uses pleated blind fabric placed between two bars pivotably connected by a slotted hinge. The blind assembly travels through the open and closed positions by the use of a slide that is connected to one of the bars. A cord is tied to the slide and the cord is knotted. The cord and knot travel through a channel in a track. In another embodiment, a spring load friction catch is provided on the end of at least one bar.
