Abstract
Abstract A wheeled cart in combination with a plurality of suitcases, vertically stacked thereon in a nested relation, with clamp means to lock the cart and suitcases in said relation. The suitcases are provided with pull-out drawers instead of being of the conventional clam opening type. Extendible leg means in combination with retractable wheels are provided on the underside of the cart to stabilize the assembly and to counterbalance the weight of the drawers and the articles therein when one or more of said drawers is pulled out. Therefore, a person such as a traveling salesman who moves from city to city after relatively brief stopovers can utilize the suitcases in a dresser-like manner without the problem of unpacking and packing in each locality. The suitcases and wheeled cart may readily be separated by the clamp means for storage in the trunk compartment of an automobile or for transportation on an airplane or other means of transportation.
