Abstract: A rolling cart comprises a frame unit defining an interior space in which items are transportable; a tire, the tire having a boundary defined by a circumference, a left edge maximum extent, and a right edge maximum extent, a distance between the left edge maximum extent and the right edge maximum extent sufficient to provide the cart with inherent lateral stability; a handle supported optionally removably from the frame, the cart moved and controlled by the handle; and the interior space at least partly within the boundary. The rolling cart may further comprise a container in which the items are transportable suspended within the interior space. The tire may include several segments, which may or may not be inflatable with distributions system for an inflation fluid including a bi-directional pump and valves.

Abstract: A rolling cart comprises a frame unit defining an interior space in which items are transportable; a wheel, the wheel having a boundary defined by a circumference, a left edge maximum extent, and a right edge maximum extent; and the interior space at least partly within the boundary. The rolling cart may further comprise a container in which the items are transportable suspended within the interior space. The container can be integral to the frame unit. In another variation, the rolling cart further comprises: a plurality of left rollers rotatably connected to the frame unit; a plurality of right rollers rotatably connected to the frame unit; a left inner surface defined by the wheel, the left inner surface contacting the left rollers for rotatable support; and a right inner surface defined by the wheel, the right inner surface contacting the right rollers for rotatable support.
