ABSTRACT:
A wheeled portable luggage carrier is equipped with a telescoping handle assembly which is movable between extended and retracted positions. The handle assembly comprises a pair of telescoping tube assemblies, and each tube assembly includes lower, intermediate, and upper telescopingly related tubes. The lower ends of the intermediate and upper tubes carry lock buttons which can extend through openings in the upper ends of the lower and intermediate tubes, respectively, to releasably lock the tubes in an extended position. The lock buttons are released by a pair of upper and lower release bars which extend between the tube assemblies adjacent the upper ends of the lower tubes. The lower release bar is movable toward the upper release bar to force the lock buttons carried by the intermediate tubes inwardly, thereby unlocking the lower and intermediate tubes, and the lock buttons carried by the upper tubes are forced inwardly by the upper release bar as the intermediate tubes telescope downwardly within the lower tubes, thereby unlocking the intermediate and upper tubes.
