摘要： A trolley with folding shelves comprising two uprights mounted on feet having castors enabling the trolley to be moved about easily, in which the shelves are each formed as a pair of half-shelves pivotable about the edge adjacent the other half-shelf of the pair, and the feet each comprise two arms which are pivotable about a vertical axis between a first position extending perpendicular to the plane defined by the two uprights and a second position extending parallel to this plane. The uprights house a connecting mechanism between the half-shelves and the arms so that when the half shelves are moved about their axes from a horizontal to a vertical position the arms are moved by the connecting mechanism from their first to their second position.
