Abstract: An expandable shelving system that can be assembled without special hardware or tools comprises vertical supports, intermediate shelves, a removable top shelf, a bottom shelf, a rotational assembly attached to the bottom shelf and a base attached to the rotational assembly. Slots along the side of the vertical supports cooperate with slots on the shelves to create an interlocking stable shelving structure. The shelves can rotate to provide access to all sides of the shelving structure. The shelving system can further include expansion vertical supports and expansion anchors to create longer vertical supports. The expansion vertical supports cooperate with the slots on the shelves to create an expanded shelving system.

Abstract: A work surface for roll-along suitcases that enables the suitcase to convert into a seat or table. The work surface can be permanently attached or removably attachable to the suitcase. The permanently attached work surface is stored in a compartment or recess with the retractable handle of the roll-along suitcase and is pivotally connected to the retractable handle. When the retractable handle is extended, the work surface pivots down away from the top of the handle to rest on the top of the suitcase. The removably attachable work surface is temporarily secured to the handle of the roll-along suitcase preferably with a tongue section that accommodates a variety of sizes of retractable handles. The removably attachable work surface rests on the top of the suitcase. Side sections of the work surface unfold to form a bigger seat or work surface.
