ABSTRACT:
An ajustable shelf assembly which, in a four corner post embodiment, preferably includes novel latch structure at each of the opposed front corners of the assembly. Each latch structure is comprised of a flex arm with a latch finger mounted on one end, the flex arm being connected to the shelf at the other end. The flex arm, which preferably is inherently flexible, is normally in a connect position generally parallel to the front edge of the shelf, the latch finger being received in a front corner post hole in that connect position, thereby connecting the shelf and corner post into a shelf assembly. The flex arm's latch finger is retracted from the connect position simply by depressing or flexing the flex arm out of the front edge parallel position by temporarily exerting a force thereon generally normal to the shelf's front edge, thereby permitting the shelf to be easily assembled with or disassembled from the corner post by exerting a manual force on the flex arm generally normal to the shelf's front edge.
