Abstract
An adjustable IV pole assembly is disclosed including an inner rod which is telescopingly received within an outer tube for adjustment of the pole height. A locking mechanism is located on a top end of the outer tube for locking the inner rod against downward movement. The locking mechanism includes an inwardly tapered surface located at an end of the outer tube and a release sleeve positioned between the inner rod and the tapered surface wherein the release sleeve carries a plurality of balls which may wedge between the tapered surface and the inner rod to lock the inner rod against movement. In addition, the release sleeve is provided with a flange portion which extends radially outwardly beyond the circumference of the outer tube and which may be manually engaged to release the locking mechanism and thereby allow the inner rod to move downwardly relative to the outer tube.
