<p>A length adjustable member includes an outer tubular member (12,112), an inner tubular member (14,114) slidably disposed within the outer tubular member, and a locking mechanism (28,128) located within the inner and outer tubular members for locking the inner and outer tubular members in any of plural longitudinal positions relative to each other. Upon rotation of one of the tubular members with respect to the other tubular member to a release position, the locking mechanism disengages to allow one tubular member to be slid with respect to the other to adjust the overall length of the adjustable member, and, when the release position is no longer held, the locking mechanism is biased to re-engage to lock the inner and outer tubular members in one of the plural longitudinal positions.</p> |
