Abstract A cabinet which contains an appliance such as a refrigerator is provided with novel hinges having one member secured to the body of the appliance and the other member adapted to carry both the door of the appliance and the door of the cabinet for simultaneous operation. The hinge members are interconnected in a known manner by means of connecting links pivotally mounted at each end to the respective member. A spring may be incorporated in each hinge for biassing the doors into the closed position.
