A refrigerator shelf translation system for a refrigerating appliance includes a movable shelf, a guide structure provided with one or more indentations, and a fixed anchoring component associated with the movable shelf and movably associated with the guide structure. The movable shelf is held in a fixed position relative to the guide structure when there is cooperation between at least one locking span of at least one anchoring component and at least one indentation of the guide structure and, on the other hand, the movable shelf may be shifted vertically relative to the guide structure when distancing from all possible locking spans of all possible anchoring components and their respective indentations of the guide structure.
