Description
- The present invention relates generally to refrigerators and in particular to top hinge locating arrangements for refrigerator doors.
- Refrigerators typically have one or two doors that may be pivotally secured to the refrigerator cabinet with hinges. With pivotally attached doors, generally there is a sealing gasket that is located on an inside side of the door which mates with a front surface of the cabinet outer wrapper to prevent leakage of air into and out of the refrigeration compartment. The door must therefore be positioned relative to the compartment opening such that the gasket will engage the cabinet wrapper to provide this seal. Usually there is a fair amount of tolerance involved, so that exact positioning of the door on the cabinet is not highly critical.
- However, in the case of side-by-side refrigerator doors, such as where there is a side-by-side arrangement of a refrigeration compartment and a freezer compartment, or where the doors are french doors opening into a single refrigerated compartment, such as shown in U.S. Pat. No. 4,288,135, incorporated herein by reference, the positioning of the doors on the cabinet, and hence, relative to one another, becomes more critical in order to avoid interference between the two doors and to assure a proper seal with the cabinet. Although the doors are secured to the cabinet in their correct locations at the factory, occasionally the doors are removed during shipping or installation, such as to fit through narrow doorways, therefore requiring that the doors be returned to their original position in order to avoid problems between the two doors and to assure proper sealing of the doors relative to the cabinet and possibly each other.
