9 Claims. (Cl. 312-295) This invention relates generally to refrigerator door structures.

Heretofore, it has been customary in the construction "of refrigerator doors to manufacture the door shelving tions for the reception of the separately formed shelving or receptacles. In other instances openings were formed in the liners or pans to receive the shelving or receptacles,

-or the anchorage means therefor, and this required, in

addition to the separate forming and assembling operat'ions, sealing gaskets about such openings in the inner liners or pans.

With the foregoing in mind, one object of this invention is to provide a one-piece panel which not only is capable of serving as a door liner or pan, but which is so shaped that it has portions that serve as compartments Thus no additional parts are necessary.

Another object of the invention is to provide a refrigerator door structure having a series of vertically spaced horizontally disposed inwardly opening compartments, and a vertically movable upright panel having an opening therein normally affording access to one of said compartments and provided at one side of said opening with an imperforate portion normally closing another of said compartments.

Another object of the invention is to provide a vertically movable upright panel provided at another side of the access opening mentioned with an'imperforate portion that normally extends across the lower part of another compartment and serves as a guard rail for articles within said last mentioned compartment.

A further object of the invention is to provide a vertically movable upright panel that is carried by and movable relative to tracks on the liner of the door.

A still further object of the invention is to provide the vertically movable upright panel with means for frictionally holding the same in selected positions of adjustment.

Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in "connection with the accompanying drawings, wherein:

Patented Aug. 4, 1959 ice.

Figure 4 is an enlarged elevational view of the vertically movable upright panel;

Figures 5, 6 and 7 are sectional views taken along the lines 55, 6-6 and 77 respectively in Figure 4;

Figure 8 is an enlarged fragmentary view of one corner of the vertically movable upright panel and showing one of the rollers and the mounting therefor; and

Figure 9 is a sectional view taken along the line 9-9 on Figure 8.

Referring now to the drawings, A is a refrigerator cabinet having upper and lower storage compartments 10 and 1.1 respectively separated by an insulated partition 12, and provided with hingedly mounted closures or doors B and C respectively.

In the present instance any suitable refrigerant circuit may be employed in the refrigerator, and such refrigerant circuit may include any suitable evaporators (not shown) within the compartments 10 and 11 respectively for cooling such compartments to the desired temperatures.

Our invention may be embodied in either or both of the closures B and C. As shown, the upper closure or door 3 has an outer panel or shell 13, and inner panel or liner 14, and suitable insulation 15 therebetween. Such outer shell and liner may be secured peripherally to each other in any suitable manner to retain the intermediate insulation in place and otherwise to provide a rigid door structure. As shown particularly in Figure 3, the marginal portions of the outer shell 13 are turned laterally inwardly to provide a reinforcing flange 16 which extends continuously around the periphery of the outer shell. The inner liner 14 is formed with a marginal portion 17 which extends continuously around the periphery thereof in substantial parallel relationship to the reinforcing flange 16 and is secured thereto in any suitable manner. A rubber gasket 18 extends continuously about the periphery of the inner liner 14 and is positioned to engage the front wall of the refrigerator cabinet A around the opening to the storage compartment 10 to provide a door seal.

The inner liner 14 is a one-piece panel throughout of any suitable material and of any suitable thickness. In the present instance, such liner, usually called a door pan, is shaped, preferably by a vacuum drawing operation to provide a plurality of vertically spaced compartments 19 to 22 inclusive and an enclosing border frame 24. Although the compartments and border frame aforesaid are preferably formed by a vacuum drawing operation, such elements could readily be produced by other operations, for example by means of any suitable die or press. The border frame 24 is a continuous inwardly projecting open return bent portion or rib of the liner 14 and is disposed in spaced relation to the marginal portions 17.

Additional substantially horizontal inwardly projecting open return bent portions or

ribs

25, 26 and 27 respectively of the liner are spaced vertically within and connect into upright opposite sides of the frame 24, while vertically spaced

upright portions

25a, 26a, 27a and 28a of the liner are located at and connect into the outer ends of the open

return bent portions

25, 26 and 27 respectively and are substantially parallel to the outer panel or shell 13. These

ribs

25, 26 and 27 cooperate with the border frame 24 and the

upright portions

25a, 26a, 27a and 28a of the liner to form the

compartments

19, 20, 21 and 22respectively. Within the compartment 21 and dividing the same into two chambers 23 is a vertically extending rib 28 of the liner.

The lowermost compartment 22 contains a removable crisper bin 29 that is preferably pivotally supported upon upstanding projections 341 of the lower substantially horizontal portion 24a of the border frame 24.

The compartments 19 to 21 inclusive and the crisper bin 29 may be employed to receive any desired types of food. However, in the present instance, the uppermost compartment 19 has a sufiicient depth to receive liquid containers or bottles. Compartment 20 contains an inverted channel member 31 having openings 31a in the top thereof for receiving eggs. The compartment 21 may be used for the storage of butter and cheese. It will be noted that the upper surfaces of the

ribs

25, 26 and 27 are slightly inclined downwardly from their inner edges to the

upright portions

25a, 26a and 27a respectively of the liner to more securely support articles of food thereon.

An upright panel 32 is provided for the

compartments

19, 20 and 21 and is movable vertically relative thereto at the front thereof. Vertically extending

tracks

33 and 34 for the upright panel 32 are respectively secured to the upright side portions of the border frame 24 of the inner liner 14.

laterally projecting flange portions 36 and 36a that are attached to the border frame 24 by suitable fastener assemblies generally indicated at 37.

The upright panel 32 includes a rectangular rigid sheet 38 and

frame bars

39 and 39a extending along and suitably secured to the side edge portions thereof. Two vertically spaced rollers 40 are rotatably secured by screws 41 to the frame bar 39 at one side edge of the upright panel 32 and are separated by spacers 42 from said frame bar. Rollers 40 fit within and have a rolling engagement with the channel rail portion 35 of track 33. Two other vertically spaced rollers 43 are provided along the opposite side edge of upright panel 32 and have a rolling engagement with the channel rail portion 35a of track 34. Each roller 43 is supported for rotation on a pin 43a extending between and anchored in the legs of a U-shaped bracket 44 which is pivotally mounted on a screw 45 carried by the frame bar 39a. Coil springs 46 encircle the shanks of the screws 45. Each spring 46 is anchored at one end 47 in an opening in the frame bar 39a, and has its other end 48 bearing against a leg of an adjacent bracket 44 to urge the bracket laterally outwardly. Accordingly rollers 43 are spring pressed into engagement with rail portion 35a of the track 34. Figure 8 shows a roller 43 pressed outwardly by a spring 46. When assembled on the door structure, each roller 43 is forced laterally inwardly relative to the panel 32 when such roller is in engagement with the track rail portion 35a and when the rollers 40 are in engagement with the track rail portion 35. The strength of springs 46 is such that sufficient friction is present between the rollers 43 and track rail portion 35a and between the rollers 43 and the pivot pins 45 on which they are mounted to cause the panel 32 to remain in any position of vertical adjustment.

Only slight manual pressure is required to raise or lower the panel 32. For this purpose a handle 49 is secured to and extends along the lower edge of the panel 32'.

Rerferring to Figures 1 to 4 inclusive and Figure 7, it will be noted that the panel 32 has an opening 51 normally affording access to compartment 20 and is provided below and above said opening with

irnperforate portions

38a and 38b. Normally the lower imperforate portion 38a of the panel 32 covers and closes access to the compartment 21 containing chambers 22. These chambers 23 normally will contain butter and cheese and are desirably covered by the panel 32 so as to maintain such foods at a slightly higher temperature than other foods in the cabinet, so that such foods may be more readily spread'when used. The upper imperforate portion 38b of the upright panel 32 normally extends across compartment 19 slightly above the rib 25 to provide a guard rail to prevent bottles or other articles or packages stored in compartment 19 from falling out. A suitable trim strip 53 is located upon the outer side of the imper- These tracks have opposed

channelshaped rail portions

35 and 35a provided with integral forate portion 38b and is secured to the upper edge thereof.

As shown in Figures 1, 2 and 3, the opening 51 is elongated and extends transversely across the panel 32. The lower edge of this elongated opening 51 is above the bottom of the intermediate compartment 20, so that the imperforate portion 38a of the panel 32 immediately below said opening 51 serves as a guard rail for articles upon the bottom of the intermediate compartment 20.

Access may be gained to the chambers 23 of compartment 21 by merely using handle 49 to raise the panel 32 to the upper position shown in dotted lines in Figure 3. The friction between the rollers 43 and track rail portion 35a and between the rollers 43 and the pivot pins 45 on which they are mounted is suflicient when the rollers 40 are in engagement with the track rail portion 35 to hold the upright panel 38 in any desired position of vertical adjustment.
