ABSTRACT:
A selective vertical locking mechanism is provided for use with a pair of telescoping tubes. A locking mechanism releasably locks the inner tube relative to the outer tube for adjustment of table height. The locking mechanism includes a housing disposed at the lower end of the inner tube. A locking element with the housing is biased against an inclined ramp fixed within the housing and, though an opening in the housing, against the inner wall of the outer tube, thereby preventing the inner tube from moving downwardly within the outer tube. A push rod and arm, actuated by a handle near the platform, pushes the locking element away from the inner wall or the ramp which allows the inner tube to move downwardly.
