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.

Dependent claims

A telescoping handle assembly for a portable luggage carrier having a wheel-equipped base, the handle assembly comprising a pair of spaced-apart parallel tube assemblies, each of the tube assemblies having upper and lower ends, the lower ends being attached to the base and extending upwardly therefrom, a handle extending between the upper ends of the tube assemblies and secured thereto, and a release bar assembly extending between the tube assemblies intermediate the ends thereof, each of the tube assemblies including a first tube extending upwardly from the base, a second tube telescopingly received by the first tube, and locking means carried by the lower end of the second tube for releasably locking the first and second tubes in an extended position, the first tube having an opening in the upper end thereof through which the locking means extends when the first and second tubes are in the extended position, the release bar assembly including a first bar extending between the first tube of each of the tube assemblies and secured thereto and a second bar extending between the first tube of each of the tube assemblies and slidably mounted thereon, the second bar being movable toward the first bar and having lock-engaging portions engageable with the locking means of the tube assemblies as the second bar moves toward the first bar whereby each of the locking means can be pushed inwardly through the opening in the first tube to release the first and second tubes and the second tube can telescope within the first tube.

A telescoping handle assembly for a portable luggage carrier having a wheel-equipped base, the handle assembly comprising a pair of spaced-apart parallel tube assemblies, each of the tube assemblies including a first tube extending upwardly from the base, a second tube telescopingly received by the first tube, a third tube telescopingly received by the second tube, first locking means carried by the lower end of the second tube for releasably locking the first and second tubes in an extended position, the first tube having an opening in the upper end thereof through which the locking means extends when the first and second tubes are in the extended position, and second locking means carried by the lower end of the third tube for releasably locking the second and third tubes in an extended position, the second tube having an opening in the upper end thereof through which the second locking means extends when the second and third tubes are in the extended position, the release bar assembly including a first bar extending between the first tube of each of the tube assemblies and secured thereto and a second bar extending between the first tube of each of the tube assemblies and slidably mounted thereon, the second bar being movable toward the first bar and having lock-engaging portions engageable with the first locking means of the tube assemblies as the second bar moves toward the first bar whereby each of the first locking means can be pushed inwardly through the opening in the first tube to release the first and second tubes and the second tube can telescope within the first tube, the first bar having lock-engaging portions engageable with the second locking means of the tube assemblies as the second tubes telescope within the first tubes whereby each of the second locking means can be pushed inwardly through the openings in the second tubes to release the second and third tubes and the third tubes can telescope within the second tubes.
