ABSTRACT:
A modular rack includes a pair of lateral frame portions with opposing inner surfaces, a shelf plate and four corner pieces. Each of the lateral frame portions includes two upright post units, each of which includes two upright pillars that cooperatively define a slot therebetween. Each of the lateral frame portions further includes a horizontal linking rod which interconnects the post units and which has an inner surface at the same side as the inner surface of the corresponding one of the lateral frame portions. Each of the corner pieces has a bottom wall, a top wall, and first and second side walls which interconnect the top and bottom walls. The first side wall extends in a direction transverse to the linking rod. The top and bottom walls and the first and second side walls cooperatively define a corner space thereamong for receiving a corner of the shelf plate therein. Each of the corner pieces further has an engaging protrusion which projects from the first side wall in a direction parallel to the linking rod so as to lie longitudinally on the linking rod while protruding into the slot. The second side wall is situated outwardly of the plane of the inner surface of the linking rod of the corresponding one of the lateral frame portions, thus resting the bottom wall on the linking rod.
