Abstract
The hinge assembly comprises a housing for mounting on a cabinet and a post member for mounting on a door and for rotation relative to the housing. A first electrical contact is mounted within the housing for connection to a source of electrical power in the cabinet and a second electrical contact is disposed in the post in electrical contact with the first contact for connection to an electrical appliance in the door. In one embodiment, the electrical contacts rotate relative to each other as the post member pivots on the housing while in other embodiments; the electrical contacts remain stationary relative to each other as the post member pivots on the housing.
