Abstract

Expandable luggage devices are provided. Included within expandable luggage devices is an expandable backpack that is convertible between at least two positions. An uppermost cover portion of the backpack converts to a side or back portion when the backpack is expanded, and a secondary cover portion is withdrawn from an internal area of the device to enclose or cover the backpack in the second position.

a first internal volume and a first cover portion associated with the first position of use, the first cover portion comprising a zipper;

an expandable sleeve portion provided substantially within the first internal volume;

the second position of use comprising a second internal volume larger than the first internal volume, wherein the expandable sleeve portion is drawn upwardly to create the second internal volume;

a second cover portion; and

wherein the second position of use is characterized in that the first cover portion is provided as a sidewall portion and the second cover portion being provided within the first internal storage volume when the luggage device is in the first position of use.

2. The expandable luggage device of claim 1, wherein the luggage device comprises a backpack.
