Patent ID: 8091916

Claim:
A wheeled carrier device including at least a hand grasp, comprising: a carrier base, defining at least a partial floor and a plurality of upright stub walls forming a side elevational plane and profile, the partial floor and walls are formed from a planar sheet of material having a pattern, a series of slits are created in the pattern to permit bending of predetermined portions of the planar sheet of material; and wherein the predetermined pattern of the planar sheet of material is folded upwards near a peripheral edge of the carrier base, the upright stub walls forming a substantially vertical plane with free upper edges orthogonal to a substantially horizontal floor plane; and at least two wheel assemblies, each of the at least two wheel assemblies including a housing defining a substantially vertical plane, with at least one wheel interconnected to the housing by a wheel axle, and wherein the at least one wheel is movable between an operative position where the at least one wheel is oriented substantially parallel with the housing vertical plane, and a stowed position where the at least one wheel is oriented substantially orthogonal to the assembly housing vertical plane, and one of each of the at least two wheel assemblies are affixed to opposing sides of the carrier device; and in the operative position the at least two wheel assemblies, and their associated wheels, provide rolling support of the carrier device, and in a second, stowed position, each of the at least one wheel's of each of the at least two wheel assemblies are located within the interior carrier space, substantially within the side elevational profile of the stub walls, and wherein at least one movable retaining upright wall is formed with a shaped angle which corresponds to shaping of at least part of a receiving slot formed in the base near the carrier perimeter so that the shaping of the retaining upright wall is retained within the receiving slot when the upright wall is placed in a first, operative position, substantially vertical to a rolling surface, and in a second, stowed position of the movable retaining upright wall it is stowed within the side elevational profile and perimeter of the base.
