  • Patent number: 5366284
    Abstract: A refrigerator storage drawer system includes a drawer having side walls with upper ledges terminating in downwardly projecting lips. Spaced apart support structures support the lips for sliding movement of the drawer. Each support includes a pair of slide type support bearings spaced apart along the support. The bearings on one side of the drawer closely interfit with the drawer to provide smooth, non-binding operation of the drawer. The bearings on the other side of the drawer provide wide slide bearing surfaces which accommodate tolerance build-up in the system. An additional bearing is positioned on the support structure above the drawer ledge, forward of the rear one of the support bearings and engages the drawer ledge if the drawer tends to tilt downwardly as it is pulled out of the refrigerator.
