3 Claims. (Cl. 220-15) This invention relates generally to refrigerator constructions, and more specifically to an improved breaker strip construction for a-refri'gerator cabinet.

As is well known inl'the art, refrigerator breaker strip constructions require that means he provided for effectively and 'efli'ciently covering "the space between the marginal edges of the inner and outer-liners of a refrigerator cabinet. These means mustbe such as to prevent any substantial conduction of heat'fr'om the outer liner, through "the means, to the inner liner of the refrigerator cabinet. Further, these means .shou'l'dbe'formed so as to present a pleasing appearance to-the refrigerator cabinet, and additionally, these means should be as simple to install and remove, and as economical, as possible.

It 'is the object of this invention toprovide .a breaker strip 'construction'which' fulfill .all of the above noted requirements in an eflicientjmanner.

It is a'feature of this invention that a plurality of novel spring clips are used in cooperation with a particular breaker strip to maintain .that breaker strip mounted'to a particular refrigerator cabinet.

Other objects .and features of the present invention will be apparent upon perusal of the following specification anddrawing of which:

Figure l 'is a'front plan view of ,a refrigerator cabinet constructedaccordingto this invention;

Figure 2 'is a partial cross-sectional view of the refrigeratorcabinet sliown inFig'tire 1 and taken along the'li'ne 2 2.

The present embodiment is the preferred embodiment, but it is .to be understood that changes can be made in the present enibodimentb'y one skilled .in the art Without departingfrom the spirit and scope of this-invention.

:For a detailed description of this invention reference 'isr'nade'to the drawing. .A refrigerator cabinet is'provided whichisgenerally constructedas any refrigerator cabinet Well-known in the art. Wherein .the structureof'the re- 'frigerator cabinet-particularly departs from the structure well-known in the art, will be noted in detail below. As to the details ofthe general constructionof the'refriger'ator cabinet, an outer .liner 10, aninner iliner 11, and arefr'ig'erator door 12 are provided. The inner liner J1 is'disposed within the outer liner and is spaced some distance therefrom. Insulation 13 eis..positioned between theinner liner 11 and the outer liner .10 to ,prevent the conduction of heat from the outer "liner to theinnerliner 11. The -o11ter marginal edges of .the .outer liner 10 and ithe'in'nerlin'er 11 are formed .to have .a particular configuration which will be .defined .in .detail below. Further, :ainachine'ry compartment 14 .is generally provided the '-lewer.;portion of .the.outer liner 10 -and below -'theinner liner 11. The refrigerator door 12 is pivotally mounted by means of thehinge structures 15 to theouter liner 10 along one vertical edge thereof. The refrigerator door 12 comprises anouter panel 16 and an inner panel 17. Theouter panel 16 has a rolled edge extending about the outer marginal edges thereof as can be seen in Figure 2. The inner panel 17 is mounted to cooperate with 2 the'outer panel '16 by means of the gasket and mounting means '18. The space between the inner panel 17 and theouter panel 16 of the refrigerator door 121s :filled with an insulating material '19, as is well-known in the art. Any door latching means 20 is further provided (and mounted to the refrigerator door 12 for cooperationwith the refrigerator cabinet to permit latching and unlatching of the refrigerator door 12.

Turning next to'a detailed'description of the breaker "strip construction, the outer marginal edges .of thefouter liner '10 are formed to have a rolled section, such as a yoder rolled section, whereby a substantially 'F-shaped flange is formed thereon when viewed in cross section'as can easily be seen in'Fig'ure 2. The'F-'shaped'flange'comprises anouter leg 21 and aninner leg 22. This construction will form a substantially Ll-shaped channel about the marginal edges of the 'outerlinerlli and above the machinery compartment'l l.

The 'outer marginal edges of theinner liner 11 .are formed to .Iprovide an outwardly extendingflange 23 which may easily be seen .in cross section in Figure 2. Thefla'nge 23 on the inner liner '11 is so formed as to lie substantially in the plane including theinner leg 22 ofthe .F-shapedflange of theouter liner 10.

To structurally strengthen the refrigerator cabinet and to maintain the insulation 13 properly'packed between theouter liner 10 and theinner liner 11, if the insulation 13 is not of a rigid type, a picture frame panel 24 is provided. The picture framepanel 24 must be ,formed'of a material'having the property of low heat conductivity and 'go'od'strength. Panel 24may be formed of some material-such as'rnaso'nite. 'The'inner and outermarginal edges of 'the'panel 24 are respectively fastened to theflange 23 and theinner leg 22 of'fthe F-shaped fiangepf 'theiouter liner 10. Any mounting means 25 well-known to the art may be used to fasten the inner edge of the panel 24 to theflange 23 of the inner liner '11. ,It isprefe'rred that the .outermarginal edge of'the panel 2410c fastenedto the :inner leg 22 of the F-shaped flange'o'f .the outer liner '10 by some means such as shown inFigureZ. This means comprises a plurality .of fasteners, suchas the fastener .26 show'n'in Figure 2, and a plurality of straps, such as thestrap 27 shown in Figure 2. Eachstrap 27 and'eachfastener 26 are connected together through'an opening provided through the panel '24, andeach of thestraps 27 is so positioned that the .innerleg22of the F- shaped flange of theouter liner 10 is sandwiched between a portion .of thestrap 27 and the ,panel 24,, ,as can be seen'in Figure '2. Each of thefasteners 26 andstraps 27 are positioned in a spaced apart relation about the panel 24 to rigidly fasten the entire outer-edge of thepanel :24 to .theinner leg 22 of the F-shaped flange of .the outer tions of the Ebreaker strip .28 are positioned about lthe space :between the marginaliedges of the outer liner '10 and the inner liner The dour sectionsof the bre'aker strip 28 :may #be :joinedat *the ends thereof by any fj'oin ing means 29 well known in art. Thebreaker strip 28 is somewhat U-shaped when viewed in a transverse cross section such as seen in (Figure 2. One edge of thebreaker strip 28 is positioned between theouter leg 21 and theinner leg 22 of the F-shaped flange of theouter liner 10, as can easily be seen in Figure 2. The other longitudinal edge of thebreaker strip 28 is posi tioned to abut the outer surface of theflange 23 of theinner liner 11.

To properly maintain thebreaker strip 28 in the aforedescribed position, andfurther, to permit easy removal ofbreaker strip 28 should access be desired to the space between theinner liner 11 and theouter liner 10, a plurality of spring clips, such as thespring clips 30 shown in Figures 1 and 2, are provided. Each of thespring clips 30 are formed of a material such as spring steel and are fashioned to be substantially G-shaped as can be seen in Figure 2. Each of the spring clips 3% is positioned within the U-shaped channel formed by the v F-shaped flange of the outer liner and in a spaced of thesespring clips 30 is positioned as described above,

eachspring clip 30 is biased against the panel 24 at the point 3% and against the inner surface of theouter leg 21 of the F-shaped flange of theouter liner 10 at the point 300. it is believed that this bias is stored within the portion 30d of thespring clip 30 when thespring clip 30 is projected into the U-shaped channel of the F-shaped flange of theouter liner 10. Further, when each of thespring clips 30 are positioned as described above, theportion 30a of eachspring clip 30 is biased to grasp the longitudinal edge of thebreaker strip 28. Each of thespring clips 30 are further biased about the point 300 to tend to rotate thebreaker strip 28 in a counterclockwise direction about thepoint 31 as viewed in Figure 2.

Thus it may be seen that to remove any one of the four sections of thebreaker strip 28 from the above described cooperation with the refrigerator cabinet, it is only necessary to draw the longitudinal edge of thebreaker strip 28 and each one of thespring clips 30 mounted thereon from the U-shaped channel of the F-shaped flange of theouter liner 10. It can also be seen, that to properly mount any section of thebreaker strip 28 in proper cooperation with the refrigerator cabinet, it is merely necessary to mount a plurality ofspring clips 30 in a spaced apart relationship along the one longitudinal edge of thebreaker strip 28, with theportions 30a of each of thespring clips 30 grasping that longitudinal edge of thebreaker strip 28, and further,

, biasing each of thespring clips 30 and positioning thebreaker strip 28 by projecting that longitudinal edge of thebreaker strip 28 within the U-shaped channel of the F-shaped flange of theouter liner 10.
