Abstract
A retractable blind assembly including a top section () with a vertically-extending blind covering material () extending between a fixed inclined head rail () and a middle rail () that is pivotable with respect to the head rail () about a pivot center that is adjacent to a lowermost end of the head rail, the head rail extending upwardly at an acute angle, the middle rail () being pivotable between a lower position, in which the middle rail extends horizontally, when the covering material is extended and an upper position, in which the middle rail extends upwardly at an acute angle and is adjacent the head rail, when the covering material is retracted, the covering material in the top section () having a generally triangular shape with an unattached short apex () about the pivot center and an opposite, unattached, long side () when the covering material is extended, a bottom section () with the covering material extending between the middle rail () and a horizontally-extending bottom rail (), the bottom rail being movable vertically between the bottom of the blind when the covering material is extended and an upper position, adjacent the middle rail, when the covering material is retracted, at least first and second lift cords () for extending and retracting the covering material, the lift cords being connected outside the blind to a cord connector (), wherein the first lift cord () is routed through the top section () adjacent its apex and long side () and the second lift cord () is routed such that it passes through the top section between its apex and long side, and wherein when the covering material () is extended, the total length of the first lift cord () within the top section () is equal to the total length of the second lift cord () within the top section.
