MICROWAVE OVEN WALLS STAMPED OUT FROM A ONE-PIECE BLANK

摘要

MICROWAVE OVEN SINGLE WALL CONSTRUCTION Metallic sheet stock is stamped to define a one-piece blank with five transverse fold lines providing five panels foldable into side-by-side closed rectangular loop sections partially defining cooking and control compartments. A forward edge of the blank has three longitudinal fold lines forming a channel framing the openings for the cooking and control compartments. A pattern of notched-out areas at the intersection of the longitudinal and transverse fold lines define gussets which are folded to a common diagonal plane with respect to the corner junctures and upon being secured to each other at the plane define a rigid frame structure supporting a cabinet door adapted for closing the opening of the cooking compartment.
