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.

1. A variable length support rod apparatus for translational support of a window treatment, comprising:
a support member having a length defined by a distance between a first end and a second end of said support member; said support member formed of a plurality of segments, each said segment being in translational engagement with an adjacent said segment; said support member configurable to a minimum length through translation of said segments toward each other to a fully contracted configuration; said support member configurable to a maximum length through translation of said segments away from each other to a fully extended configuration; said length of said support member being variable between said minimum length and said maximum length; a continuous flexible member positioned along a member pathway running between said first end and second end of said support member; a first portion of said flexible member extending a first length, between said first end and said second end of said support member; a second portion of said flexible member extending a second length, between said second end of said support member and a movable return located in a central portion of said support member; said moveable return being movable relative to said second end of said support member; said second length of said second portion of said flexible member decreasing and said first length of said first portion of said flexible member concurrently increasing, during any increase of said length of said support member; said second length of said second portion of said flexible member increasing and said first length of said first portion of said flexible member concurrently decreasing, during any decrease of said length of said support member; translation of said first portion of said flexible member providing means for a translation of a window treatment adapted for support by said support member; and whereby said support member being configurable to any said length between said minimum length and said maximum length of said support member, and being configurable to be fixed to a support surface without an adjustment of a fixed length of said flexible member.
