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.

1. Field of the Invention
The present invention relates to a modular rack, more particularly to a modular rack having a corner piece which is not easily damaged during transport, which imparts enhanced stability to the modular rack, and which facilitates assembly of the modular rack.
2. Description of the Related Art
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which:
FIG. 1 is a perspective view illustrating a conventional modular rack;
FIG. 2 is a partly exploded perspective view illustrating a connecting unit of the conventional modular rack;
Referring to FIG. 4, the modular rack 3 according to the first preferred embodiment of this invention is shown to include a pair of lateral frame portions 4, four shelf plates 5 and a plurality of corner pieces 6.
The lateral frame portions 4 have opposing inner surfaces. Each of the lateral frame portions 4 has two upright post units 41 which include a front one and a rear one. The rear ones of the post units 41 of the lateral frame portions 4 are connected to each other by means of two crossed connecting bars 42. Each of the post units 41 includes two upright pillars 411 which have circular cross-sections and which cooperatively define a vertical slot 412 therebetween. A foot member 43 is provided on a bottom end of one of the pillars 411 of each of the post units 41 so that the post units 41 are capable of standing on a ground surface in a stable manner. Each of the lateral frame portions 4 further includes a plurality of horizontal linking rods 413. Each of the linking rods 413 has two opposite ends which extend into the slots 412 of the post units 41 for connection with the post units 41, and has an inner surface at the same side as the inner surface of the respective one of the lateral frame portions 4.
Referring to FIGS. 4 and 6, each of the shelf plates 5, which are made of wood in this embodiment, is disposed transversely between the lateral frame portions 4, and has a flat top surface 51 for placing objects thereon and four corners 52 to be mounted to the post units 41. Each of the shelf plates 5 has four of the corner pieces 6 mounted respectively on the four corners 52 thereof.
