ABSTRACT:
A handle assembly is provided for a collapsible luggage trolley of the type having two outer tubes and two inner tubes respectively, telescopically received in the outer tubes. Each inner tube includes a link received therein for controlling telescopic movements of the inner tube relative to the outer tube. The handle assembly includes a handle having two ends each having an operative surface. The handle is manually rotatable relative to the end blocks to cause the operative surfaces to exert a force on the links for controlling telescopic movements of the inner tubes relative to the outer tubes. Two end blocks are respectively connected to the ends of the handle. Each end block has a first end rotatably connected to an associated end of the handle and a second end connected to an associated link to move therewith. A button member is mounted in a compartment of the handle and includes two rods respectively extending outwardly from two ends thereof. Each rod is engaged with the associated link to move therewith for controlling telescopic movements of the inner tubes relative to the outer tubes upon manual press of the button member
