Abstract
A wheeled upright luggage case is disclosed. The best embodiment of the case has wheels to allow the case to stand upright in a stable and balanced position without attendance by the user. The case has a wheel handle to allow the user to push or pull the case across a supporting surface. The case may be pushed or pulled on either four wheels or two wheels. When four wheels are used, the full weight of the case and its contents are borne by the wheels, relieving the user from having to bear with her arm any of the weight of the luggage. The body of the case is designed to have a specific range of tilt angles from the vertical; by tilting the body of the case toward the user, the design of the case improves the stability of the case while it is pushed across a supporting surface on four wheels. Various case body configurations and push handle arrangements are disclosed.
