Abstract
Abstract The shelving comprises receiving troughs, with many supporting rods mounted between the upper and the lower receiving troughs to allow them to be piled one over another for being fixedly assembled with the engaging stubs on the bottom ends of the supporting rods inserting into the top location holes on their respective lower receiving troughs, each engaging stub has a protruding rib on one of its sides for firmer connection; the posts have rollers on the feet and with top holes thereon to allow insertion of the stubs, so that the shelving after assemblying can be pushed to move about; when disassembled, the receiving troughs can be fittingly lapped over one another, the supporting rods, also the posts, can be collected four in one group to form a cylinder shape, as is beneficial to saving space, shipping and storage.
