Abstract
Abstract A Portable Luggage Carrier (10) having a resilient mounting surface (24) to accept hand luggage, with castors (48) and (50) providing mobility and weight receiving characteristics. A structural frame (20) provides a rigid mounting surface and attachment for the castors (48) and (50) that are retractable into the frame body (20). A flexible towing strap (52) with a slideable buckle (54) is interposed with the frame (20) and encompasses luggage that is juxtaposed on the mounting surface. The strap (52) is tightened with the buckle (54) and the remaining end becomes a hand held towing strap. A securing latch (36) is spring loaded into the retractable member (25) or (26) to lock the castors into either the extended or retracted position. The preferred embodiment includes a removable cover (61) that slips over the carrier exposing the handle thorugh a slot in the cover. In another embodiment the carrier comprises a combination brief case and cover (73). In still another embodiment a hinged back cover (62) encloses the carrier (70). This cover is locked in place and may incorporate a flashing light (66) and a clock (68).
