ABSTRACT:
A collapsible luggage carrier has a base with depending peripheral walls forming a boundary enclosed underside in which hinged wheel brackets are affixed to the underside at hinge points spaced from one another a distance sufficient to allow wheels carried by the brackets to be collapsed inwardly in opposed folded non-overlapped relation. A U-shaped cross-section lock bracket is hinged to one of the peripheral walls or to a cross wall with the legs of the bracket directed inwardly towards the underside of the base, the legs being spaced apart a distance sufficient to engage the wheel brackets in both the wheel collapsed and wheel extended positions and to retain the wheels respectively in each of said positions.
