  • Patent number: 7065832
    Abstract: An upper hinge assembly for pivotally mounting a door to a refrigerator cabinet includes an aligning plate fixedly secured atop a hinge plate to the cabinet. Once the hinge and aligning plates are factory set in position, with tight tolerances between fasteners and holes in the aligning plate, the aligning plate is separately fixed to the hinge plate. The hinge plate can be subsequently detached from the cabinet, with the aligning plate remaining affixed to the hinge plate, and then reattached in a manner which enables the desired factory preset position to be reestablished, thereby assuring that a seal between the door and the cabinet can be effectively maintained.

  • Publication number: 20050156494
    Abstract: A refrigerator includes a multiple slide crisper system. More specifically, a universal crisper pan and support frame for a refrigerator can be used with various, distinct glide arrangements, including friction, roller or ball bearing glides. For frictional sliding movement, crisper pan side walls slide directly upon molded inner rails on the frame. With the roller system, various rollers are fitted to a rear portion of the crisper pan through the use of pins, while commensurate rollers are mounted at front portions of the frame. When using ball bearing glides for a precision slide support, the glides are preferably mounted to the support frame at an acute angle to the axis of travel of the friction and roller glide systems.

  • Publication number: 20050017618
    Abstract: A refrigerator cabinet includes a shell having first and second laterally spaced, upstanding side walls that are interconnected by a top wall, each of the walls includes an in-turned front edge portion defining a liner receiving cavity. The shell further includes a mullion bar, which partitions the shell into first and second liner cavities, and a base member. Both the mullion bar and base member have respective liner receiving portions. With this arrangement, first and second liners are adapted to be inserted into their respective cavities and flexed such that three sides are inserted into the liner receiving cavities, while the remaining side is positioned against a land of the mullion bar or base member. Once in place, the liners are secured through a mullion bar cover and a base member cover. This construction combines the benefits of a front-load process with that of a flex-load process, lowering assembly time without the need to reinforce the liner.
