- 1:4 claims. (c1. al1-15s) This invention relatesto refrigerators and more particularly to shelves therefor.

One of the objects of the present invention is to provide a refrigerator with a shelf of new and 15- construction and combinations of parts to be hereinafter described' with reference to the accompanying drawing and then claimed.

In the accompanying drawing which illustrates suitable embodiments of the present invention: 20 Figure l is a perspective view of a refrigerator, showing a shelf of the present invention disposed therein; f

2 is an enlarged fragmentary front view of the refrigerator illustrated in Figure 1, more clearly showing the shelf and the mounting therefor;

Figure 3 is a fragmentary section taken approximately on the line 3 3 of Figure 2, showing the shelf supporting means in side elevation, and.l

also showing the shelfin dotted outline in another of its adjusted potions;

Figure 4 is an enlarged fragmentary perspective view of one corner of the shelf, showing the molmting means therefor; and Y Figure 5 is a section taken similar to Figure 3 of a shelf having a modified mounting means.

Referring more specifically to Figs. 1-4 of the accompanying drawing in which like numerals refer to like parts throughout the several views, 40 the vertical side walls I0 of the food compartment of the refrigerator II are provided with opposed pairs of suitable shelf plugs I2 which support the shelves I3. If desired one or more of the shelves I3 may be provided with the supporting brackets 45' to be hereinafter described. n

Referring to the construction shown in Figures 2-3and-4, the shelf I3, which may be of any suitable construction or design, comprises an article supporting portion which is provided at each side 50 witha pair of depending brackets A which coopcrate with the shelf plugs II in shelf supporting relation.

Each supporting bracket A is preferably in the form of a single piece ,of strap or bar stock which ilshapedbybendingthesamebackuponiiself to provide spaced end portions I I which are securely welded or otherwise secured to the adjacent side piece of the shelf I3, a depending portion I5 doubled upon itself at spaced intervals to form a' plurality of plug receiving recesses or notches I6, 5

. and a reversely bent portion I1 abutting the portion I5 to add rigidity to the bracket.

Each of the notches I6 is inclined from its forward open side upwardly toward the shelf side rod, as shown in Figures 3 and 4, so that when the l0 shelf plugs I2 are received in any particular pair of notches I6, the forward end'portions of the upper adjacent projections Ilia will extend slightly below) the plane of the upper surfaces of the plugs I2 to prevent inadvertent sliding of l5 the shelf I2 on the plugs I2 such as might occur when articles are placed on the shelf were it not for theinclination of the notches. The inclined projections Ita of 'the depending portions I5 of the brackets A, which provide the notches IS, thus serve as stops or abutments whichresist the tendency of the shelf I3 to slide on the plugs I2 while articles are being placed on the shelf.l

The shelf I3 may be easily and quickly changed from one level to another by simultaneously lifting and moving the same toward the back wall of the refrigerator until the desired level is reached, and then disposing the same by a. forward movement so -that the notches I6 for that level will receive the shelf plugs I2. 30

In Figure 3, the shelf I3 is shown in its uppermost position in solid outline, andin its lowermost position in' dotted outline.

, Although in the construction shown in Figures 2, 3 and 4, the brackets A are shown to be of one 35 piece construction and embodying notches for Vonly three shelf positions it is ,to be understood that, the same may be of any other suitable construction and provided with any desired number of notches IB. I 40 In the modified construction shown in Figure 5. the forward supporting bracket B is formed from a. single piece of bar stock which is bent back and. forth upon itself to provide the plug receiving notches Il, the uppermost notch being formed partially by the adjacent shelf side rod. In this case, however, the notches Il are horizontally disposed instead of at an angle as in the construction previously described. f

'I'he rearmost bracket C in this case, however, 50 comprises a depending element I9 welded or otherwise secured to the shelf side rod, and a number of spaced short projecting portions 20 arranged at an angle and suitably secured thereto to provide plug receiving notches 2 I. The inclined 55 projecting portions 20 as in the construction shown in Figure 5, serve to prevent inadvertent sliding movement of the shelf I3 when the shelf plug I2 is received in any of the three lowermost notches 2I. movement when the Ashelf plugs I2 are received in the uppermost notches I8 and 2| of the brackets B and C respectively, the side rods of the shelf I3 are offset at their forward ends as indi-l cated at 22 in Figure 5. Theseportlons 22 are offset a suilicient extent to prevent inadvertent sliding of the shelf, but not to such an extent as to interfere with the changing of the shelf from one level to another, the operation of which is the same as in the construction shown' in Figures 2, 3 and 4.

Either bracket B or C of Figure 5 may be substituted for one of the brackets A of Figure 3, or if desired the bracket A may be substituted for either the bracket B or the bracket C, or both brackets may be of the type exemplified by the bracket C.

In each of the embodiments of my invention described I have provided a shelf construction having an improved multi-position supporting ymeans for providing an eillcient and easy adjust- `ment thereof from one level to another, which is simple in construction and which can be economii cally manufactured.

Aside from the specic embodiments olf the invention herein shown and described, it will be understood that numerous details of the construction may be altered or omitted without departing from the spirit and scope of the invention.

What I claim is:
