The edges of top and bottom shelves having front and rear sections separated by a seam are pivotally coupled to the main frame to be in a closed position when in a vertical position, and connecting rods are pivotally coupled to the front and rear sections of the top and bottom shelves which transfer motion of one of the sections of a shelf to the same section of the other shelf. |
