Abstract
An extendable and retractable column which is formed from at least three linked sections. The linked sections include a plurality of individual sections linked end to end. As the linked sections are extended, each of the individual sections engage adjacent individual sections to form a column. As the linked sections are retracted, each of the individual sections disengage from the adjacent individual sections and the column may be retracted for compact storage. Methods of forming such an expandable/retractable column are also presented.
