Abstract
Abstract A collapsible cargo carrier is the subject of the present invention. The carrier comprises a rigid framework for supporting cargo and an axle and wheel assembly for moving the cargo over a surface. A generally rectangular framework supports the cargo and is coupled with the axle by triangular supports which are releasably hinged to the cargo carrying framework. By removing two locking pins, the axle is released from the framework and the triangular supports can be collapsed against the cargo carrying portion of the framework. Mounting brackets are provided for storing the axle and wheel assembly on the side of the framework when the other components have been collapsed. Accessories are provided for accommodating larger loads and for facilitating movement of loads by providing elongated handles on the carrier.

Claim 1
Independent Claim
164 words
A collapsible cargo carrier comprising: a framework for supporting said cargo in a raised position relative to a surface; first and second generally triangular brace members hingedly coupled with said framework on opposite sides thereof and movable from a folded position generally parallel with said framework to a cargo carrying position generally perpendicular to said framework; a removable axle extending between and connecting said brace members for supporting said framework and said brace members in said cargo carrying position; means for releasably locking said brace members to said axle in said cargo carrying position; means on said framework for securing said cargo to the framework; first and second wheels adapted to be releasably coupled with said axle means for accommodating rolling movement of said cargo over said surface; and means on said framework for mounting said axle when removed from said brace members to accommodate rolling movement of said cargo carrier on said wheels when said triangular brace members are in the folded position.
