ABSTRACT:
A collapsible luggage carrier comprises a handle having portions adjacent its lower end adapted to provide support for an article in a first plane and a base joined to the handle for articulation between an extended position in which portions of the base provide support for an article in a second plane disposed substantially orthogonally to the first plane and a collapsed position in which the second plane substantially coincides with the first plane. Transversely spaced-apart wheeled carriages received on the lower end of the handle portion pivot between positions in which they are extended to orient the axes of rotation of the wheels in parallel relation to the first plane and positions in which they are retracted to orient the axes of rotation of the wheels orthogonally to the first plane. A cam arrangement moves the wheeled carriages between the extended and retracted positions automatically in response to movements of the base between its extended and collapsed positions.
