The system is assembled of a support frame (1), one stationary board (3), and several shelves (2), preferably in the shape of grids. Each of the shelves (2) is divided lengthwise into three sections, which can be swiveled around two horizontal axles in order to be hidden at the rear of the system when there is no appropriate amount of goods left to cover all the shelves (2) available.
