Abstract:
A sliding device for providing sliding backward and forward movement of a drawer-type storage container relative to a storage case, the storage container being slidably mounted inside the storage case, and said sliding device comprising:a first plurality of roller; a second plurality of rollers; a fixed rail fixedly mounted to an inner side surface of the storage case and including a roller coupling portion rollably receiving said first plurality of rollers; a movable raid fixedly mounted to an outer side surface of the storage container and including a roller coupling portion rollably receiving said second plurality of rollers; and a middle rail slidably mounted between the fixed rail and the movable rail for providing a coupling relationship therebetween and for guiding the rolling motion of the first and second plurality of rollers such that the movable rail and the storage container slide together by means of a rolling motion of the second plurality of rollers along the middle rail, and the middle rail slides along the fixed rail by means of a rolling motion of the first plurality of rollers, the middle rail further comprising: an upper rail portion including an upper channel for receiving the roller coupling portion of the movable rail therein and for guiding the sliding motion of the movable rail; a lower rail portion including a lower channel for receiving the roller coupling portion of the fixed rail therein and for guiding the sliding motion of the middle rail, a partition rail portion integrally connecting the upper rail portion and the lower rail portion while partitioning the upper channel from the lower channel, and the fixed rail includes a guiding space for receiving the upper rail portion and the movable rail includes a guiding space for receiving the lower rail portion.
