Abstract
A storage apparatus includes trays, a shaft, a base element and two wheel assemblies. The shaft is inserted in the trays to connect the trays to one another so that each of the trays is rotatable between a withdrawn position and a spread position relative to a lower one of the trays. The base element is attached to the shaft. The base element is connected to a second one of the trays by a connecting element. The base element is located below the lowermost tray when the trays overlap one another. The first wheel assembly includes wheels attached to the lowermost tray. The second wheel assembly includes wheels attached to the base element. The wheels cover a first area when the trays overlap one another and cover a second area when the trays fully spread from one another. The first area is smaller than the second area.
