Abstract: A spring-biased extendable and retractable hanger assembly with a roller, support lines and a return line configured to facilitate retraction of the fully extended hanger bar includes a spring-biased window shade style roller assembly. The roller assembly features a pair of mounting pintles that extend from opposed ends of the roller. As the support lines are extended, the roller rotates in an extension direction and the roller's spring is wound, so that a biasing force is generated which will restore the assembly to a desired position upon disengagement, such as by quickly rotating the roller in the extension direction and releasing. The support lines are configured to support the hanger bar at a desired height when the lines are fully extended. The return line is longer than the support lines by an additional length sufficient to wrap around the roller one or more times when the support lines are in their fully extended position. The bottom end of the return line is a free end.
