Abstract: Disclosed is a novel enhanced structural connector and method of using the structural connector. The device comprises a male member that may engage and interconnect with a female member. Male member comprises a male protuberance that is received by a female notch. Male protuberance and female notch resemble and operate similarly to dovetail connectors common in the art and carry load on the inward surfaces when interconnected. Also disclosed is a novel cup-like member comprising multiple female members that serves as a node for interconnection of a plurality of structural components.

Abstract: A mullion is attached to a cabinet shell of a refrigerator through the use of a retainer that includes a laterally extending portion positioned between primary and secondary flanges of the cabinet shell, and a longitudinally extending portion that is interengaged with additional flange structure defined by the mullion. Clips formed on the retainer engage wall portions formed by the mullion flange structure to secure the retainer to the mullion. A tab formed on the retainer engages a keyhole formed in the secondary flange of the cabinet shell, thereby aiding in securing the retainer to the cabinet and preventing the mullion from undesirably shifting in either a horizontal or vertical manner.

Abstract: A refrigerator water filter assembly is provided in the ceiling of a refrigerator and is adapted to hinge downwardly from the ceiling for changing the filter cartridge. The cartridge is normally partially recessed within the ceiling so as to minimize the use of space in the food compartment of the refrigerator. The filter assembly includes a base mounted in the refrigerator ceiling, a manifold pivotally mounted on the base, a filter cartridge attached to the manifold, and a cover pivotally mounted on the manifold so as to be movable between open and closed positions. When the cover is opened, the filter cartridge is angled downwardly from the ceiling for easy grasping by a person for replacement of the cartridge.

Abstract: A chiller compartment is provided that secures to the inside of a refrigerator door. The chiller compartment includes a pair of french doors that are connected by a linkage that causes the doors to simultaneously open or close. The french doors of the chiller compartment open and close automatically when the refrigerator door is open and shut. The chiller compartment also includes a tray of sufficient height to secure tall beverages or food items and prevent such items from toppling out of the chiller compartment while the refrigerator door is opened or closed.

Abstract: Methods and devices for retaining a heating element, such as warm refrigerant tubing, within a refrigerator cabinet. Semispherical raised dimples are formed upon a retaining panel in a rolled triple flange. The dimples are intermittently positioned along the retaining panel and maintain the warm refrigerant tubing in intimate surface contact with the exterior surface panel of the refrigerator. The raised dimples preclude significant intimate surface contact between the retaining panel and the tubing and permit insulating foam to be disposed between the two so that heat transfer is minimized. A dimpled flange arrangement is also used to retain tubing within a mullion. A sheet metal insert is also described that is formed having two retaining panels with raised dimples thereupon that maintain the tubing in intimate surface contact with the exterior surface panel that forms the facing for the mullion.
