US Patent 7500547 Collapsible expanding luggage

A collapsible piece of luggage is disclosed. The piece of luggage may have wheels and an extendable and retractable handle. The sidewall, bottom and cover of the luggage have sufficient rigidity to hold their own shape and may be folded into a storage configuration in which the piece of luggage is smaller in width and depth. Additionally, the luggage includes an expansion feature that allows the luggage cover to expand outward pyramidally so as to increase the storage volume of the luggage.
