Abstract: A drawer fixing mechanism for fixing a drawer to a desk without using screws and rivets is provided. The mechanism prevents the drawer from being deformed, shifted or separated from the desk by impact applied, to the desk. The fixing mechanism comprises a fixing member outwardly extending along upper edges of a drawer and having insertion holes corresponding to the through holes and an insertion groove at its bottom, an intermediate frame combined with a stand, and bots and nuts for assembling elements of the desk. The intermediate frame has a plurality of connection holes formed to correspond to the insertion holes. The bolts are inserted into the through holes of an upper panel, the insertion holes of the fixing member combined with the drawer, and the connection holes of the intermediate frame in order, and the nuts are combined with the respective bolts at the bottom of the intermediate frame.

Abstract: A multifunctional bookshelf, the bookshelf including an upper plate, a lower plate and a plurality of middle plates, wherein the bookshelf comprises: lighting unit mounted at the upper plate to provide a lighting to a lower front side thereof; a plurality of container bodies provide at the upper plate, the lower plate and the middle plates; and insecticide, dehumidifier, deodorizer and aromatic stored in the plurality of container bodies, such that dehumidifying and insect-proof functions thereof promote the property of preservation of data stacked on shelves, stench is prevented from generation and sufficient illumination is supplied, thereby providing users pleasant environment.
