Spring-biased extendable and retractable hanger with a roller, support lines and return line configured to facilitate retraction of the fully extended hanger

A spring-biased extendable and retractable hanger assembly comprising

• a roller, said roller being rotatably mounted, said roller including
• a pair of mounting pintles that extend from opposed ends of the roller;
• one of the pintles having an other than round cross-section and extending from a shaft associated with a winding spring in the roller;
• and
• the other pintle having a rounded cross-section and being freely rotatable when mounted;
• and
• means for controlling motion of the roller, said means for controlling motion winding the winding spring as the roller rotates in an extension direction and the support lines are extended so that a biasing force is generated which will restore the roller to a retracted position upon disengagement of the means for controlling motion of the roller;
• and
• a plurality of support lines, each support line having a top end and a bottom end;
• a return line, the return line having a top end and a bottom end;
• and
• a hanger bar;
• wherein
• the top end of each support line is attached to said roller and the bottom end of each support line is attached to said hanger bar;
• and
• said return line is configured to facilitate retraction of the fully extended hanger bar;
• wherein when the hanger bar is fully retracted, the support lines are fully wound around the roller and when the support lines are fully extended, objects may be hung on the hanger bar and the entire load is carried by the support lines;
• and
• wherein the bottom end of the return line is a free end and the return line is longer than the support lines by a determined additional length which is enough additional length to wrap the return line around the roller at least one more time when the support lines are in their fully extended position.
