Telescopic traversing system for retractable window treatments

摘要

A variable length support rod apparatus for translational support of a window treatment, such as draperies, comprised of a support member formed of a plurality of transnationally engaged segments, the support member is infinitely configurable from a minimum contracted length to a maximum extended length through a translation of the plurality of segments toward or away from each other. A continuous flexible member is positioned along a pathway running between a first end and a second end of the support member. The support rod may be configured to any length between the minimum and maximum lengths and may be fixed to a support surface without an adjustment of the fixed length of the continuous flexible member.

主权项

1. An adjustable length support apparatus for use in hanging a window treatment over a window, the support apparatus comprising:
a support member having a pair of telescoping segments translatable relative to each other to adjust the support member to the size of the window; a pulley system coupled to the support member and having at least one pulley translatable relative to both telescoping segments; and a cable coupled to the pulley system; the pulley system and cable being configured to transition between a first configuration and a second configuration relative to the support member as the pair of telescoping segments translate relative to each other; the pulley system, cable and support member being configured to enable movement of the cable through at least a portion of the pulley system while the pair of telescoping segments remain stationary relative to each other.
