BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a drawer fixing mechanism for a desk, and more particularly to a drawer fixing mechanism for a desk for fixing a drawer to an upper panel serving as a working place without using screws or rivets but using bolts and nuts, thereby preventing a drawer from being deformed and damaged.

2. Description of the Related Art

Generally, a desk comprises an upper panel providing a working place, a drawer provided under the upper panel and in which books and other items are received, and a stand for supporting the drawer at both sides.

Referring to FIG. 4 , a drawer 120 having an interior space 121 therein is secured to the bottom of an upper panel 110 made of wood using screws or rivets.

Since the drawer 120 is fixed to the upper panel 110 by a plurality of screws or rivets, assembling or disassembling work of the desk is complicated and consumes a lot of time. Further, since the bottom surface of the upper panel 110 is usually damaged by such riveting work, the bottom surface of the upper panel cannot be used instead of the upper surface of the panel in the case that the upper surface of the upper panel is damaged.

Accordingly, to solve the problem above, a stand 130 is used. That is, the drawer 120 is simply placed on the stand 130 , and the upper panel 110 is placed on the drawer 120 . The stand 130 is secured to the bottom surface of the upper panel 110 by bolts and nuts. Therefore, the drawer 120 is not secured to the upper panel 110 and the stands 130 . Accordingly, when an external impact is applied to the desk, the drawer 120 is easily separated from the upper panel 110 and/or the drawer 120 can be broken, and the bolt and nut assembly is loosened, so that the upper panel 110 and the stand 130 may be separated.

Further, since the drawer is made of polyvinyl chloride (PVC) resin, it is easily deformed by load etc. and the deformed drawer must be replaced with a new one.

Bolts 140 penetrates the upper panel 110 , the drawer 120 and the intermediate frame 2 from the upper surface of the upper panel 120 to the bottom of the intermediate frame 2 , and nuts 150 are combined with ends of the bolts 140 .

The upper panel 110 has a rectangular or a square shape, and has a plurality of through holes 111 at every corner.

The drawer 120 has a plurality of grooves 3 formed at the bottom surface thereof. A fixing member 1 is provided to outwardly extend from upper edge portions of the drawer 120 . The fixing member 1 has a plurality of insertion holes 11 penetrating therethrough from its upper surface to its lower surface. The insertion holes 11 are formed to correspond to the through holes 111 of the upper panel 110 . The fixing member 1 further has an insertion groove 12 on the bottom thereof. In the insertion groove 12 , a plurality of fixing protrusions 12 a is provided for holding and fixing the intermediate frame 2 in the insertion groove 12 of the fixing member 1 . The drawer 120 having a complicated structure described above may be formed by an injection molding method.

The intermediate frame 2 is formed in such a manner as to fit into the insertion groove 12 of the fixing member 1 , and has a plurality of connection holes 22 formed to correspond to the insertion holes 11 . A hook 23 is provided at the bottom of the intermediate frame 2 between adjacent connection holes 23 . The stand 130 is combined with the intermediate frame 2 at a rear part of the intermediate frame 2 , and a height of the intermediate frame 2 from the ground is adjusted by adjusting a height of the stand 130 .
