Patent ID: 7708156

Claim:
An adjustable shelving system comprising: a first side rail and a second side rail, each of the first and the second side rails extending between an upper end and a bottom end; at least one cross piece interconnecting the first side rail and the second side rail such that the first side rail is substantially parallel to the second side rail defining a plane in which the first and the second side rails lie; at least one shelf assembly attachable to the first and the second side rails in at least a storage position and a use position, wherein the at least one shelf assembly is movably attached to the first and the second side rails and hangs downwardly in a generally vertical position when in the storage position, and wherein the at least one shelf assembly is movably attached to the first and the second side rails and extends generally horizontally from the first and the second side rails when in the use position; and a first elongated base element and a second elongated base element, each of the first and the second elongated base elements extending between a proximal end and a distal end, wherein the bottom end of the first side rail is attached to the first elongated base element closer to the proximal end than the distal end of the first elongated base element, wherein the bottom end of the second side rail is attached to the second elongated base element closer to the proximal end than the distal end of the second elongated base element, wherein each of the first and the second elongated base elements is adjustable to an angle greater than 90 degrees from the plane defined by the first and the second side rails so as to allow multiple adjustable shelving systems to be nested together.
