ABSTRACT:
An extendable column consisting of a plurality of axially elongated rigid structural sections nested within one another. Each section includes a plurality of screws running the length thereof and rotatably attached therein. The next inner section includes threaded lugs oriented to threadingly engage the screws thus resulting in extension or retraction of the column upon rotation of the screws. The screws of each section are selectively rotated by a motor and an engagement mechanism.
