My invention relates to refrigerators and has for an object the provision of an improved re frigerator structure which is sturdy yet readily assembled and ‘inexpensive. . Another object'is to provide improved distri 5 bution of the weight of a refrigerating apparatus in a cabinet.- 7 ' My invention together with the ‘objects and (C1. 62-89) - . of a generally U-shaped metal plate,” extend ing from the top of the posts 24 and 25 to ap proximately the levelv of the front cross member H. The plate 3|) forms the supportingstructure for a refrigerating apparatus 3| the cooling ele ment 22 of which is adapted to be disposed within . the storage compartment ||. The front section of the cabinet including the ' frame l3, the liner I8 and insulation members 23, sideration of the following descriptionin con and the rear section including the corner posts 24, 25, the plate 30 and the refrigerating appa junction with the accompanying drawings form ratus 3|, are telescoped together by inserting the ing part of this speci?cation, and’ of which: Fig. 1 is a perspective view of a refrigerator cooling element 22 through the liner opening frame ~2| into the storage compartment | |, form cabinet embodying the invention; ' ' Fig. 2 is a vertical section of the refrigerator; ing a double cantilever arrangement whereby Fig. 3 is a horizontal section taken on line 3-3 both sections are mutually supporting. The plate 30 is provided with a block of insulation material in Fig. 2; and 32 which is disposed within the liner opening Fig. 4 is a rear view of the ‘refrigerator. Referring to Fig. 1, a refrigerator cabinet l0 frame 2|. The liner. opening ‘is sealed on the p -20 provides a thermally insulated storage compart-r inside by a liner opening trim member 33.

To the liner opening frame 2|, and the 40 front frame |3 are secured a plurality of' insu lating members 23 consisting of corrugated card board sheets faced with metal’foil, in ‘spaced rela tion to each other and parallel to the liner it. The sheets 23 are provided with ?anges '31 and 45 may be secured to the liner opening frame 2| and the front frame l3 by nails or other fastening back of the cabinet for air cooling of the re frigerating apparatus 3|. A ?anged bottom plate 36, secured to the sides of the cover 34 along its lower edges, to the front frame (4 3, and to the plate 30, serves to reinforce the structure. Various changes may be made within the scope of my invention as indicated by the following claims. ' . What is claimed is: 40 ' v ' 1.
