SHELF Filed July 25, 1940 Inventor": Ge orge C. Han-bison,

Patented June 23, 1942 SHELF George C. Harbison, Erie, Pa., assignor to General Electric Company, a corporation of New York Application July 25, 1940, Serial No. 347,456 6 Claims. -(Cl. 211-150) My invention relates to shelves for cabinets such as refrigerators and the like.

Shelves of relatively small area have hitherto been provided in refrigerators and disposed in the space between the cooling element or evaporator and one of the side walls, thereby utilizing this space for storage purposes as for the support of small articles. been removable or arranged to tip up or both in order to increase the storage space for tall articles, such as bottles, which may then be placed upright on the next lower shelf.

It is an object of my invention to provide a new and improved shelf of this type which shall be easily positioned in one of a pluralityof vertically spaced-apart positions, or moved to a position permitting the upright storage of tall articles whereby the maximum flexibility of 'arrangement is obtained.

It is another object of the invention to provide a shelf of the above described type which is slidable and has selective vertical positions.

Further objects and advantages of my invention will become apparent as the following description proceeds and the features of novelty which characterize my invention will be pointed out with particularity in the claims annexed to and forming a part of this specification.

For a better understanding of my invention reference may be had to the accompanying drawing in which Fig. 1 is a partial view of a refrigerator provided with a shelf embodying the principles of my invention; Fig. 2 is an enlarged perspective view of the shelf shown in Fig. 1 in one position thereof; Fig. 3 is a perspective view of the shelf of Fig. 2 in its tipped up position; Fig.4 is a perspective view of the shelf of Fig. 2 in its inverted position; and Fig. 5' is men- I larged cross sectional view illustrating details Inasmuch as the refrigerating machine is not a.

part of my invention, the complete details thereof are not shown as any suitable refrigerating device may be employed. A suitable thermal control arrangement is provided including a temperature adjusting device I 5 mounted on the Such shelves have the compartment II, I have provided a pair of shelves I8 supported on either side of the cooling element from the side walls by means of brackets or supports l9.

Each of the shelves l8 comprises a border frame comprising end portions 20 and 2| and

side portions

22 and 23. The side portion 23 is displaced out of the plane of the shelf l8 for a purpose to be hereinafter described. The frame in the plane of the shelf I8 is completed by a portion 24 suitably secured at the ends thereof to the border frame as by welding. In order to provide an article supporting surface, a plurality of spaced-apart longitudinally extending members 25 is provided, the members being secured to the end portions 20 and 2|, respectively, in any suitable manner as by welding, for example. In order to provide a neat and distinctive appearance, a decorative strip 26 has been applied to the frame portion 20. If desired, a similar decorative strip may be applied to the other end portion 2|. 4

In order to support the shelf I8, I have provided a pair of brackets or supports I9. Each of the brackets I9 is provided with a guide slot 2'! therein for slidably receiving one of the

side members

23 or 24, these side members thus forming cooperating supporting portions for the shelf. The brackets are secured to the side wall 28 of the food compartment II by suitable means such as a screw 29 threaded through apertures in the bracket I 9 and wall 28 into threaded engagement with a nut 30 welded to the outside surface of the wall 28. In order to obtain a quiet smooth sliding action between the border frame of the shelf and the brackets, the supporting brackets I are preferably formed of some non-metallic substance, such for example as a resinous condensation product having a suitable filler, for example,-the material obtainable on the market under the trade name of Textolite.

In order to limit the outwardly sliding movement of the shelf I 8, the brackets l9 are placed near the front of the side wall 28 so that engagement between an end border frame and the rear bracket will prevent further outward movement.

In order to protect the finish on the rear food compartment wall I provide a buffer member 3| of some suitable material, as rubber for example, so arranged as to engage the shelf at the end of its inward sliding movement.

In order positively to maintain the shelf 18 in a horizontal position I have provided each bracket with a depending portion l9 as by cutting away a portion of each of the brackets 19 to provide a bearing surface 32 or stop against which one of the

shelf supporting portions

23 or 24 is adapted to bear. Thus, when the shelf is in the position shown in Figs. 2 and 5, the supporting portion 24 serves to support the shelf from the brackets I9 while the portion 23 cooperates with surface 32 to maintain the shelf It! in a horizontal position. In the shelf position shown in Fig. 4, the supporting portion 23 'engages the slots or grooves 21 while the supporting portion 24 performs the function of maintaining the shelf in the horizontal position. It will be readily seen that this construction renders the shelf readily movable and it will also be seen that the shelf may be rotated or pivoted about the supporting member disposed in the slot 21. -If it is desired to store relatively tall articles on the shelf IS, the shelf l8 may thus be removed or tilted into the position shown in Fig. 3. In order to retain the shelf I8 in its tilted or tip-up position, I have provided a suitable retaining member, such as a headed stud 33, so positioned as to engage the side frame portion 22 as shown in Fig. 3. I'he ends of the article supporting rod adjacent the side portion 22 are displaced at each end thereof to permit passage of the headed stud.

Because of the above-described construction, it will be seen that the provision of the spacedapart supporting portions of the shelf [8 serve to provide selective, vertically spaced-apart positions of the shelf by inversion of the shelf. Thus, if it is desired to provide more storage space between the shelf i8 and the top wall of the storage compartment, the shelf may be placed in the position shown in Fig. 4. On the other hand, if more room is desired for storage purposes between the shelf 16 and the shelf l8, the shelf may be inverted and replaced in the position shown in Figs. 1 and 2. Of course, additional space may be provided by removing or tipping the shelf, as described.

While I have shown a particular embodiment of my invention, other modifications will readily be apparent to those skilled in the art. For example, instead of employing a pair of spacedapart brackets l9, one bracket of sufficient length to rigidly support the shelf may be used. I do not therefore desire my invention to be limited to the particular construction shown and described and I intend in the appended claims to cover all modifications within the spirit and scope of my invention.

What I claim as new and desire to secure by Letters Patent of the United States, is:
