Display shelf device having a rigid structure

摘要

A display shelf device comprises a pair of opposing side walls and a shelf mounted on the side walls. The mutually facing inner upright surfaces of the side walls are formed respectively with a pair of substantially horizontal grooves. Each groove has a first section adjacent to the respective upright surface and a second section remote from the respective upright surface. Each groove has a vertical size greater at the second section than at the first section. The shelf is provided at its opposite side edges with mounting means. The mounting means are received in the grooves such that the side walls are interconnected by the shelf. The mounting means include locking means received in the second sections of the grooves to lock the mounting means in the grooves. The locking means have a vertical size greater than the vertical size of each groove at the first section.
