ABSTRACT:
A one-piece frame for a refrigerator shelf is produced from a planar blank having first and second side members that extend at an angle from a central cross member. The side members are folded along bend zones located between each of the first and second side members and the cross member such that, once folded, the first and second side members extend outward from the cross member forming a three-sided frame. At this point, edge portions of the first and second side members are folded along additional bend zones to form upper flanges. Preferably, an upper edge portion of the cross member is folded along still another bend zone to form a hook element. The hook element is designed to engage with a shelf support member provided in the refrigerated compartment such that the shelf frame is supported in a cantilevered manner.
