June 27, 1944.: T. WuRUNDELL REFRIGERATOR 2 Sheets-Sheet 1 Filed Nov. 24, 1941 June 27, 1944. RUNDELL I 2,352,345

I REFRI GERATOR Filed Nov. 24, 1941 2 Sheets-Sheet 2 tented June 27, 1944 This invention relates to new and useful imrovements in domestic refrigerators and more lcularly to a new and improved shelf contruction therefor.

Domestic refrigerators of the conventional type enerally have their interior storage compartent provided withooneiprhmore horizontally disposed shelves, and these shelves usually'are throughout the height of the storage compartment. In most refrigerators, however, the space between adjacent shelves is not great enough vertically to permit large commodities, such as roasts, watermelons, and the like, to be inserted therebetween and, in many cases, this condition 6 has unduly limited the utility and storage facilities of domestic refrigerators. 'For this reason it is desirable that domestic refrigerators be provided. with one or more shelf structures having at least s. portion or portions thereof that can be manipulated or positioned out of the way so as to provide sufficient clearance or height for commodities that are taller than the normal space between adjacent shelves of the refrigerator.

With the foregoing in mind, the principal 011- ject of the present invention is to provide a novel shelf construction for domestic refrigerators which embodies a plurality of articulated sections movable relative to each other and to the shelf so that one or more of said sections may be moved from its normal position in the shelf thereby leaving an opening in said shelf through which my project or extend relatively large commodities and articles supported upon an underlying .or lower shelf.

Another object of the present invention is to provide a shelf construction of the type described for domestic refrigerators which embodies novel features of construction and operation yetis o comparatively simple and easy to use.

A further object of the invention is to provide a shelf construction of the character set forth for domestic refrigerators which is of neat ap pearance and relatively inexpensive to menufacture.

These and other objects of the invention and the various features and details of the construction and operation thereof are hereinafter set I forth and described, and shown in the accom panying drawings, in whlch: f

perspective of a shelf embodying the present invention and showing the articulated sections thereof in their normal position for supporting articles and commodities thereon; and

Figures 3, 4 and 5, respectively, are sectional views on line A-A, Figurev2 showing other positions in which the articulated shelf sections may be disposed with respect to each other and the shelf proper in accordance with the invention.

Referring now more particularly to the drawings, there is shown in Figure 1 thereof a heatinsulated refrigerated compartment I that is open at the front and provided with a heat-insulated door 2, the compartment I being cooled by any suitable refrigeration equipment including an evaporator 3 arranged in the upper portion of said compartment. Suitable shelves 4, 5, 6 and I are arranged horizontally in vertically spaced relotion within the compartment I, and these shelves may be made of open-work wire construction as shown so as not to interfere with the circulation of air in said compartment I.

- Ihe present invention is concerned particularly with the construction and operation of the shelf 1, and, as shown in Figure 2 of the draw- I inns, this shelf 1 embodies a peripheral frame comprising a member 8 having side and rear portions 9 and I0 respectively and an intermediate portion Ii which extends substantially parallel to the side portions 8 forwardly from the rear portion id of said member 8. The front or for ward ends of one side portion 9 and the intermediate portion are permanently connected together by a frame portion 12 and intermediate said one side 9 and the intermediate member ii a supporting structure for articles is provided by means of a plurality of wire elements it arranged in spaced parallel relation with their opposite ends permanently secured upon the rear and front frame portions ll and I2 respectively as shown.

In order to provide sufficient rigidity and strength to the shelf I and particularly its frame structure I, there is provided a reinforcing frame member I. This reinforcing frame member ll comprises side, rear and intermediate portions ll, II and i1 respectively which are spaced below thecorresponding portions 9, l0 and H of the frame 8 although, as shown, the side portions II are relatively short and have their end portions bent upwardly and permanently secured to the overlying frame side portion 9, as at I50, while the intermediate portion l'l inclines forwardly to a point closer the front end of the intermediate portion H where the end portion of said portion I1 likewise is bent upwardly and permanently secured to said portion II, as at Ha. In addition, a strut I8 is secured between the frame member 8 and the reinforcing member H at the points of connection therewith of the intermediate portions H and I1 respectively.

Between the other side and intermediate portions 9 and II of the frame 8 and substantially parallel to the rear portion thereof, there is permanently secured a member Hi. This member I9 is spaced forwardly of the frame rear portion III a short distance as shown and connected for pivotal movement by hinges 20 to said member I9 is one of a pair of articulated shelf sections 2| and 22 respectively. These shelf sections 2| and 22 are connected together for relative pivotal movement by means of hinges 23 and each of said sections comprise a

peripheral frame member

24 and 25, respectively, and secured upon the front and rear portions of these frame members are a plurality of

wire elements

26 and 21 respectively arranged in spaced parallel relation as shown.

The sections 2| and 22 are of such size and shape that when disposed in coplanar position with respect to each other and the frame member 8, said sections occupy and substantially fill I the space or area bounded by the frame intermediate portion the side portion 9 and the connecting member l9 as shown in Figure 2 of the drawings.

For supporting the sections 2| and 22 in the coplanar position just described there is provided on each of said sections a pairof lugs 28 and 29, respectively which project laterally from the opposite ends or sides of said sections and are arranged to engage downwardly upon the adjacent frame side and intermediate portions 9 and I respectively as shown.

With the two sections 2| and 22 thus positioned with respect to each other and the shelf frame 8 there is provided and, afforded a maximum of space or area for supporting articles upon the shelf 1. However, should it become necessary to provide clearance or space within the peripheral boundary of said shelf 1 through which articles supported beneath the shelf I may project because of their too great height, the articulated shelf sections 2| and 22 may be pivoted relative to each other and to the shelf proper into the position shown in Figure 3 of the drawings thereby positioning said sections substantially out of the way and affording a clearance or opening of maximum area for such articles.

On the other hand where such a large clearance or opening is not needed and it is desired to make use of some of the shelf space provided by the articulated sections, the sections 2| and 22 may be closed upon each other and pivoted upwardly so that the normally front edge of the section 22 clears over a lug or pin 30 which projects forwardly from the rear portion I6 of the k reinforcing frame M as shown in Figure 4 of the drawings after which the sections may be lowered into the position shown in Figure 5 with the section 2| in its normal supporting position coplanar with the shelf 1 and the folded under section 22 supported in an elevated out-of-the-way position by the pin or lug 30. With this arrangement it will be seen that the section 2| is useable in the normal manner as a part of shelf 1 for supporting articles thereon while the removed position of section 22 provides a substantial opening or clearance through which articles supported below shelf 1 may project. I

The shelf 1 may be supported horizontally within the compartment I, as shown in Figure l of the drawings, by providing on the opposite 'side walls of the food compartment pairs of studs or the like on which the side portions 9 of said shelf may rest, and for the purpose of removably securing said shelf in this horizontal position against accidental displacement, there may be provided on each of the shelf frame side portions 9 a depending rearwardly facing hook element 3| and a depending finger 32 arranged respectively for cooperative engagement with the previously mentioned studs, for example, in the manner shown and described in applicant's copending application Serial No. 361,970 filed October 19, 1940.

Thus it will be seen that the present invention provides a novel shelf construction for domestic refrigerators wherein one or more portions or sections of the shelf may be moved into different positions relative to each other and to the shelf so as to provide openings in the shelf of different areas through which may project articles and commodities supported or positioned beneath the shelf. The invention further provides a shelf that is not cumbersome and is quite simple and easy to manipulate in use.

While a particular embodiment of the invention has been disclosed herein, it is not intended that the invention be limited to such disclosure but that changes and modifications may be incorporated within the scope of the claims.
