Abstract: A shelf includes a floor plate, a cam plate, and a first pin joint plate. The cam plate extends away from an upper surface of the floor plate. A top edge of the cam plate is opposite a bottom edge of the cam plate that is mounted to the upper surface and has a concave shape that curves inward toward the upper surface. The first pin joint plate is mounted to the floor plate to extend away from a lower surface of the floor plate. The first pin joint plate is configured to mate with a second pin joint plate mounted to a first wall. The top edge of the cam plate is positioned to abut a tab mounted to the second wall when the floor plate is rotated toward the second wall. The upper surface faces the second wall when the floor plate is rotated toward the second wall.

Abstract: An air flow system for the freezer compartment of a refrigerator includes air inlets located at an upper rear portion of the freezer compartment which direct a supply of cooling air forward and against both top and side walls of the compartment. The air then flows along an upper portion of the compartment toward a front thereof where it is re-directed downward and rearward. The bottom wall of the freezer compartment is provided with a plurality of upstanding, laterally spaced ribs upon which food items can be supported. Since the ribs are spaced, numerous channels are formed which extend from the front portion of the compartment to adjacent the rear wall. A gap is preferably created between the rear wall and the ends of the ribs such that air is permitted to flow laterally along a lower rear portion of the compartment. Air outlets or returns are also provided in the lower rear portion of the compartment for recycling of the air.
