Abstract: An apparatus and method for selectively positioning a shade along an arcuate path to cover at least a portion of an arched window and to correctly align the shade within a window frame to prevent gaps or over-extensions of the shade with respect to the window. The apparatus includes a linear rail for securing the shade, an actuating device for extending and retracting single or dual shades simultaneously and an alignment device to correctly align the outer peripheral edges of the shade to the peripheral edges of the window. The actuating device can include a spring-loaded cord system to simultaneously rotated arms carrying portions of the shade. The actuating device can also include a gear and hinge device. The alignment device includes an arcuate ramp that corresponds to the configuration of the window for eliminating gaps between the shade and the outer periphery of the window when the shade is in a closed position.

Abstract: An apparatus and method for selectively positioning a shade along an arcuate path to cover at least a portion of an arched window. The apparatus includes first member immovably associated and spaced from the arched window. The apparatus also includes a second member rotatingly associated with respect to the first member. The second member is rotatable between at least first and second angular positions to move the shade between an extended position and a retracted position. The apparatus also includes members for selectively positioning the shade along the arcuate path including a biasing member and a compressible member.
