Abstract
A double-pivot door hinge is disclosed that is particularly suited for household appliances such as refrigerators or microwave ovens. The hinge arrangement allows the appliance door to be opened a full 180 degrees from its closed position without coming into contact with a flush mounted wall such as an abutting kitchen cabinet. The hinge has a first pivot pin and a stop arrangement which allows a door to be swung outwardly until a 90-degree position is reached whereby the stop arrangement is engaged. Upon further outward movement, the assembly shifts to a second hinge pin until a 180-degree position is reached. The movement from the 90-degree position to a 180-degree position requires the overcoming of a spring force of the hinge arrangement.
