Abstract: By providing a plurality of cylindrically shaped tube members (21) nested together in coaxially aligned relationship, with each tube member being connected to a separate and independent control segment (22, 23, 24, 25), with the control segments being constructed for raising and lowering the associated tube segment, an easily produced, reliable, dependable, and highly portable telescopically extendable and retractable multi-element system is realized. In the preferred embodiment, each control segment incorporates a separate endless loop drive belt (35) which is cooperatively associated with a pair of pulleys (34, 35) mounted at opposed ends the segment. Furthermore, each control segment is interconnected to the endless loop drive belt of an adjacent segment for causing all of the segments to move simultaneously in response to the initial movement of a first control segment.
