ABSTRACT:
A shelf assembly for a refrigerator or freezer that is fabricated from a plurality of sheet metal stampings that are connected by welds and receive a tempered glass shelf that has an elastic seal secured to its peripheral edge. Welding processes are used in fabricating the frame that produce a very strong weld and eliminate the possibility of rust forming along the weld. The welding processes used in fabricating the frame produce a weld, that when machined and painted is not visible to the naked eye. A zinc..; chromate coating is applied to the frame assembly after which it is painted using a solid-emulsion or powder coating. The finished product thus appears to be formed from a single sheet of material. The seal includes a vertical wall that rises from the glass shelf to creates a reservoir that will contain a spill and confine the spilled liquid to the shelf surface. The seal can be formed by an extrusion process, molded as a separate component or molded to the edge of the glass shelf. The shelf storage system can be mounted at any vertical location in the compartment by mating the mounting hooks of the shelf to appropriate slots in the ladder brackets.
