Abstract
A spring loaded button, positioned interiorly of an inner tube, protrudes through a hole in the inner tube into latched relation with a preselected one of a series of longitudinally spaced holes in a telescoped outer tube. The button is manually depressed inwardly of the outer tube when the relative position of the inner and outer tubes is to be changed, the button thereafter being released to spring out through another hole in the outer tube to hold the tubes in a different relative position. A catch lip is mounted on the outer end of the button. The catch lip is sized to engage the edge of the outer tube's hole in the event of a slight longitudinal and/or oscillatory movement between tubes to tend to impede or hinder premature and undesired unlatching during normal use of the tubes. But the catch lip is not sized to prevent manual unlatching movement of the button against the spring bias when a position change between tubes is desired.
