Abstract
An adjustable height support column comprises a base plate and a support plate joined together by an axially adjustable linking mechanism. The linking mechanism includes a first threaded shaft attached to the base plate and a second threaded shaft attached to the support plate, where the two shafts are hollow and can engage each other telescopically. The linking mechanism further includes a bridging mechanism which permits the shafts to translate axially relative to each other while maintaining a fixed relative rotational orientation. A coupling member threadably engages the outside of the shaft so that rotation of the coupling member effects axial translation of the shafts relative to each other.
