Cargo carrying and holding device, expandable wall support, and method

A method of carrying cargo comprising the steps of:

• releasing a releasable retainer disposed with a case, the case comprising four beams;
• separating the four beams and expanding them into a parallel orientation;
• holding the four parallel beams in the parallel orientation;
• wherein the separating and the holding of the four beams comprises moving four first legs outwardly from a first center hub assembly and forming a first wall support;
• wrapping and holding a cover about the beams and the first wall support and forming four sidewalls and a bottom wall of a cargo carrying device;
• and
• placing cargo into the wrapped cargo carrying device and carrying the cargo.

An expandable wall support comprising:

• at least three beams, each of the beams having a first end portion disposed at a first side and a second end portion disposed at a second side, wherein the first side is opposite the second side;
• at least three legs having a first end in rotational cooperation with each of the first end portions of each of the beams;
• a first center hub assembly having a first hub portion, a second hub portion, and a guide;
• wherein the first hub portion is in rotational cooperation with each of the three legs at a first point proximate a second end of the first legs;
• wherein the second hub portion is in hinged cooperation with each of the first legs at a second point, the second point being spaced from the first point and nearer the first end of the first legs;
• wherein upon the wall support being disposed in the expanded orientation, the first hub portion is disposed adjacent or proximate the second hub portion along the guide and the first legs are disposed outwardly from each other and proximate the first side of the wall support;
• wherein upon the wall support being disposed in a contracted orientation, the first hub portion is disposed apart from the second hub along the guide and the first legs are disposed substantially parallel with each other;
• each of the beams being configured and disposed to form longitudinally extending corners of the wall support, upon the wall support being disposed in the expanded orientation, and to form an outer case enclosing the first center hub assembly and the legs, upon the wall support being disposed in the contracted orientation.
