A portable, variable capacity locker having detachable shoulder straps, wheels, a handle, at least one detachable compartment, and a expandable compartment, of which the intended primary use is for storage of books and schools supplies in lieu of a school locker. The locker defines a storage compartment having a top closure and an expandable lower portion. The expandable lower portion is defined by a flexible expansion sleeve, wherein the mating parts of a zipper, or other suitable closure, are respectively provided at the top and bottom edge of the expansion sleeve. By fastening together the top and bottom edges of the expansion sleeve, a circumferentially zippered wall is formed above the base. Thus, when the zipper is zipped and the sleeve is in a collapsed state, a functional and sturdy pack may be formed for shoulder transport by decreasing the storage compartment volume; when the expansion sleeve is in its expanded state (i.e. the zipper is unzipped), the sleeve is allowed to unfold to vertically enlarge the walls of the pack and increase the volume of the storage compartment. Wheel assemblies are attached to the base thus enabling the user to roll the locker on the surface when the compartments are fully extended and loaded. The locker also includes a detachable pouch with a security tether, and detachable shoulder harness straps which serve an alternative function as a pull strap. |
