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. The alignment device can also include a linear guide to extend or retract the linear edges of the shade. The alignment device also includes a spring mechanism to eliminate gaps between dual shades when the shade is in a closed position.
