Abstract

An arched-window shade (1) has a plurality of left-side blades (2) and right-side blades (3) with center ends oppositely disposed and attached pivotally to at least one blade axle (7, 8, 28) positioned centrally on a sill (4) of an arched window (5). The left blades are juxtaposed side-by-side and linked together consecutively with at least one left link line (24) and the right blades are juxtaposed side-by-side and linked together consecutively with at least one right link line (25). A left draw string (11) is attached to a select one of the left blades at a design distance from its center end and a right draw string (12) is attached to a select one of the right blades at a design distance from its center end. The draw strings are routed over a lift support (18, 30, 31) positioned centrally above the at-least-one blade axle, then downward and outward on line supports (19, 20, 22, 23). The left blades of the shade are opened and closed by raising and lowering the left draw string. The right blades of the shade are opened and closed by raising and lowering the right draw string. Balance of weight between the blades and weighted handles (13, 14) in combination with friction between the lift supports and the draw strings prevents the blades from falling to open positions of the shade without hand-raising the draw strings separately.
