Abstract

Abstract A refrigerator cabinet having a metal outer shell and a plastic inner liner, containing a partition between fresh food and freezer compartments formed of a metal plate defining the fresh food compartment ceiling, a rigid expanded styrene bead thermally insulating divider mounted on the plate, and a plastic tray forming the freezing compartment floor mounted on the divider. An elongated strip of flexible polyurethane is folded lengthwise over a vertical edge of the plate so as to form a compressible, resilient air tight thermal seal between the sides and back of the plate and the adjacent liner walls regardless of changes in the gap distance between the plate and liner caused by the thermal variations of refrigerator operation or reasonable manufacturing variations. The partition inserts into channels formed on the sides of the liner which are partially defined by upper ledges with overlap raised flat rims extending along the sides of the tray to prevent unsightly gaps from occurring between the tray and the liner as a result of thermal or manufacturing variations. Laterally projecting tabs formed on the sides of the rims at the front of the tray project behind frontal edges of the outer shell a distance sufficient to prevent unsightly gaps between the sides of the tray and the edges of the shell resulting from thermal variations or manufacturing variations.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 180 words
Compartment partitioning means for a refrigerator cabinet of the type containing an outer shell and a plastic inner liner comprising a metal plate defining a surface of a fresh food compartment and having a raised edge extending along the sides and back thereof, an elongated strip of compressible, resilient material folded longitudinally across and along said edge to form a thermally insulating seal between said plate and the adjacent walls of said liner, a mass of insulating material forming a thermal compartment divider disposed against said plate, said strip also forming a thermally insulating seal between said plate and divider, a plastic tray defining a surface of a freezer compartment and having raised flat rims extending along the sides thereof, said tray being disposed against said divider, said plate, divider and tray forming a partition, and a pair of channels formed on the sides of said liner and being partially defined by a pair of ledges which overlap said flat rims such that said liner and tray may be spaced relative to one another without producing an unsightly gap therebetween.
Claim 2
Dependent Claim 180 words
Compartment partitioning means for a refrigerator cabinet of the type containing an outer shell and a plastic inner liner comprising a metal plate defining a surface of a fresh food compartment and having a raised edge extending along the sides and back thereof, an elongated strip of compressible, resilient material folded longitudinally across and along said edge to form a thermally insulating seal between said plate and the adjacent walls of said liner, a mass of insulating material forming a thermal compartment divider disposed against said plate, said strip also forming a thermally insulating seal between said plate and divider, a plastic tray defining a surface of a freezer compartment and having raised flat rims extending along the sides thereof, said tray being disposed against said divider, said plate, divider and tray forming a partition, and a pair of channels formed on the sides of said liner and being partially defined by a pair of ledges which overlap said flat rims such that said liner and tray may be spaced relative to one another without producing an unsightly gap therebetween.
Claim 3
Dependent Claim 27 words
The partitioning means of claim 1 wherein said plate defines a ceiling for said fresh food compartment, and said tray defines a floor for said freezer compartment.
Claim 4
Dependent Claim 16 words
The partitioning means of claim 1 wherein said elongated strip is constructed of polyurethane foam material.
Claim 5
Dependent Claim 15 words
The partitioning means of claim 1 wherein said divider is constructed of expanded styrene bead.
Claim 6
Dependent Claim 44 words
The partitioning means of claim 1 further comprising a pair of tabs laterally projecting from the front sides of said tray behind frontal edges of said outer shell to permit said tray to become spaced relative to said shell without producing unsightly gaps therebetween.
Claim 7
Dependent Claim 109 words
Compartment partitioning means for a refrigerator cabinet of the type containing an outer shell and a plastic inner liner defining sides, a back and an access opening comprising a plastic tray defining a surface for a refrigerator compartment and having raised flat rims extending along each side thereof, and a pair of elongated channels formed on the sides of said liner and extending between said access opening and back, said channels each being partially defined by an upper ledge which overlaps a different one of said rims such that said liner and tray may expand and contract toward and away from one another without producing unsightly horizontal gaps therebetween.
Claim 8
Dependent Claim 109 words
Compartment partitioning means for a refrigerator cabinet of the type containing an outer shell and a plastic inner liner defining sides, a back and an access opening comprising a plastic tray defining a surface for a refrigerator compartment and having raised flat rims extending along each side thereof, and a pair of elongated channels formed on the sides of said liner and extending between said access opening and back, said channels each being partially defined by an upper ledge which overlaps a different one of said rims such that said liner and tray may expand and contract toward and away from one another without producing unsightly horizontal gaps therebetween.
