Abstract:

The cart comprises a platform supported on wheels. A plurality of vertical supports support a frame member at a spaced distance from the platform. The frame member defines a first opening disposed over a compartment. A door closes the opening to allow a user to isolate the compartment from the external environment. The door pivots from the closed position to the open position about two axes such that the door can be opened and the compartment accessed from different positions around the cart. In one open position the door is stopped in an upstanding, substantially vertical position such that the door is easily opened and closed. In a second open position the door extends downward against the side of the cart such that the door does not obstruct access to the compartment.
