Claims6
A window covering, comprising:
- a movable rail;
- an extendable covering material connected to said movable rail and defining an extended position and a retracted position;
- a drive cord functionally connected to said covering material;
- a hollow wand body functionally connected to said drive cord, wherein pulling on said hollow wand body moves said covering material from one of said extended and retracted positions to the other of said extended and retracted positions;
- a retracting spring inside said hollow wand body which retracts the drive cord into said hollow wand body;
- a brake mounted on said hollow wand body so as to selectively prevent the spring from retracting the drive cord into said hollow wand body, said brake being normally disengaged to allow said spring to retract the drive cord into said hollow wand body, and said brake including an actuator which, when engaged by the user, causes the brake to prevent the spring from retracting the drive cord into said hollow wand body.
