Abstract
A shade for an arched window including an arched track with a movable carriage and a shade member attached to the carriage. A cord actuates the carriage to move along the track and pull the shade member between collapsed and extended positions. A central hub permits the shade member to move laterally as the shade member is moved between the collapsed and extended positions.
Claims23
A retractable window covering for covering an arched window, the window covering comprising:
- an arched track having an interior groove, a first end and a second end;
- a carriage slidably mounted to the interior groove and movable between the first end and the second end;
- a shade member having an upper rail and a lower rail with a shade extending therebetween, the upper and lower rails each having an inner end and an outer end, the outer end of the upper rail attached to the carriage, the shade member configured to move between a first fully retracted position and a second fully extended position;
- and
- a hub engaging the inner end of the lower rail, said hub having the capability of allowing the inner end of the lower rail to move toward or away from first end of the arched track, the hub configured to push the lower rail outward toward the first end of the arched track when the shade member is in the fully retracted position, allow movement of the lower rail away from the first end as the shade member is moved from the fully retracted position toward the fully extended position, and move the lower rail toward the first end as the shade member nears the fully extended position.

A window shade for an arched window, the shade comprising:
- a cellular blind;
- a curved track;
- a carriage slidably mounted to the track and releasably connected to the blind;
- a cord positioned within a groove of the track and connected to the carriage, a loop of the cord extending from an end of the track;
- a hub engaging an inner end of the blind and permitting movement of the blind between the hub and the end of the track, the hub biasing the blind toward the end of the track;
- wherein pulling on one side of the loop of the cord moves the cord within the groove and moves the attached carriage along the track, and movement of the carriage along the track moves the blind between collapsed and extended positions;
- and,
- further wherein, the hub is configured to push a lower rail of the blind outward toward an end of the curved track when the blind is in the fully retracted position, allow movement of the lower rail away from the end as the blind is moved from the fully retracted position toward the fully extended position, and move the lower rail toward the end as the blind nears the fully extended position.
