Abstract: The present baggage carrier frame, comprising two foldable sections of truss-like configuration with a foldable platform at the lower end, provides enhanced frame stiffness with minimum increase of weight. The positive locking mechanism for holding the sections in operating relation is incorporated in the truss-like structure and effectively resists bending in either direction. Release of the lock is facilitated by tapering form of the upper frame section. The lower frame section includes rigis foot structure which performs the dual function of holding the carrier erect in loading position and supporting the platform member in traveling position. Further structural features are described which promote the effective operation and economical fabrication of the luggage carrier.
