  • Patent number: 10575638
    Abstract: An appliance having a drawer assembly that has features that facilitate organization and user access to the contents of the drawer assembly is provided. In some exemplary embodiments, the appliance, such as a refrigerator appliance, includes a drawer movable between a retracted position and a withdrawn position. A bin is rotatably coupled with the drawer between a received position and an expanded position. When the drawer is moved outward from a chamber defined by the appliance to the withdrawn position, the features of the drawer assembly automatically rotate the bin from the received position to the expanded position such that the contents within the bin are readily accessible. When the drawer is moved the retracted position, the features of the drawer assembly automatically rotate the bin to the received position so that drawer assembly may be retracted within the chamber of the appliance.
