US Patent 7568583 Upright rear wall extension for refrigerator shelves

An extending vertical wall secures to the rear edge of a shelf assembly inside a refrigerator compartment. The vertical wall comprises a vertical panel with two downwardly protruding legs. The legs removably reside within sockets included in the rear edge of the refrigerator shelf assembly. When the vertical wall is attached to the refrigerator shelf assembly, the vertical wall prevents items placed on the shelf from toppling off the back edge of the shelf assembly. At the user's discretion, the vertical wall may be quickly and easily removed from the shelf assembly. In an alternative embodiment, the wall is a formed retainer having an inserted U-shape such that the legs are received in the shelf sockets.
