11 Claims.

This application is a continuation of our application Serial No. 668,091, filed April 26, 1933, made for the purpose of correcting a mistake in the original showing and description as to the part now illustrated in Figure 5.

Our invention relates to shelved refrigerator doors forming additional storage means available to the circulating cold air within the cabinet. Such doors are disclosed and claimed in the patent to Constance Lane West, Reissue No. 19,008, dated November 21, 1933.

Our invention is an improvement upon the shelving for such doors, and its object is to provide for especially convenient and efficient storage of the articles in such doors. A further object is to provide a structure for this purpose in a form permitting ready cleaning and affording ample ventilation of the contents. Other objects will appear in the course of the following description.

Our invention in its preferred embodiment comprehends the provision of a shelf. structure mounted on the inner side of a refrigerator door, preferably so as to be readily removable therefrom as a complete unit. Preferably, such a unit is made up of a series of wires or rods rigidly assembled to form a vertical series of shelves. The door may be formed with a recess in its inner side, such as the door disclosed and claimed in the, patent to Constance Lane West, Reissue No. 19,008, dated November 21, 1933. In such case, the recess is preferably formed with inwardly diverging top, bottom and side walls, with the shelf structure shaped accordingly, to fit the side walls.

Our invention is not limited to provision of a shelf structure in a recess of the door, however. The door may be one with a recess in its interior, or it may be the usual unrecessed door, and by curtailing the depth of the shelves in the body of the refrigerator, or increasing the depth of the refrigerator body, or both, room may be left for the shelving on the interior of. the door. Our invention is novel in this broader aspect as affording the convenience above noted; and especially when constructed as a unit readily removable from and replaceable on the door.

An example of a preferred embodiment of our invention is illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of a refrigerator with our invention embodied therein.

Figure 2 is a transverse cross-section of a refrigerator door and adjacent portions of the refrigerator walls, the door being open, and the shelf structure being shown in top plan, the door flange being slightly modified over that shown in Figure l.

Figure 3 is a corresponding vertical section, the

door being closed, and the shelf structure being shown in end elevation.

Figure 4 is an inner side elevation of the shelf structure. I

Figure 5 is a detail perspective view showing the egg compartment.

The refrigerator body I has the front door opening 2 of the usual beveled and stepped formation. The door 3 is mounted as usual on hinges 4 at one side of the door opening 2, and it will be understood that it may have the usual lock or latch 4', or any other details usual in refrigerator doors.

The door 3, as herein shown, is similar to that in the above mentioned application, the forward extension 5 corresponding to the shape of the door, and-with a rim 8 all around, to which the hinges 4 and the latch or other details may be conveniently attached in the usual manner.

The extension 5 has a hollow interior or recess I, with a flat back wall 8 and inwardly diverging side walls 9, top wall l0, and bottom wall II. The door as shown is made up of the interior plate l2, outside plate l3, and edge parts l4 shaped to fit the beveled and stepped door opening, and the space thus enclosed is filled with any suitable insulation material l5.

The recess 1 therefore will be seen to have a smooth, widely opening interior adapted for ready cleaning. To fit removably in this recess,

the shelf structure or unit I6 is made up, as herein illustrated, of two upright members l1, each formed of a wire or rod bent into U-shape with its bottom slanted at the angle of the bottom wall H of the recess. The inner or rear side of the U-shape has its upper end lower than the upper end of the front side. To the tops of these legs is fixed the top member l8, formed by bending a wire or rod into an approximately trapezium shaped closed loop, with the sides of the upright U-shaped member I! at the front and rear of the member I8, at considerable distances from its corners. The angles of the ends of the loop correspond to those of the side walls 9 of the recess, and the upright U-shaped members H are correspondingly disposed, so that their rear or inner sides are considerably closer together than their front sides. Also, due to the difference in heights of the front and rear sides of these members H, the top loop member l8 slopes backwardly or inwardly; its angle of slope corresponding to that of the top wall ll of the recess. The height of this structure thus determined is considerably less than the height of the recess.

Additional loop members l9, as here shown four in number, are of approximately the same trapezium shape as the top loop member l8, and are arranged in vertical series at approximately equal intervals from the bottom of the structure and from each other and from the top member l8, and the sides of the upright U-shaped members I! are fixed to them in the same relation thereto that they have to the top member it. These additional loop members I! are not rearwardly or inwardly slanted, however, but lie in horizontal front to rear planes. Intermediate transverse rods or wires have their ends fixed to the ends of these additional loop members I9 at intervals between the front and rear sides of the upright U-shaped members II, as here shown being three in number of each member l9. These form the lower shelves of the structure. A short distance up from the front of each loop member IS, a guard wire or rod 21 extends transversely, with its ends fixed to the front sides of the upright U-shaped members l1.

It is quite advantageous to provide'an 688 P00 et or compartment in the topmost shelf of the unit. The eggs will here be out of the way and in the safest position against accidental contact and breakage. The compartment is formed by a series of wires or rods 23 bent up at their ends at 23c and there secured by welding to the loop l9 similar to that forming the other shelf, which loop is secured by welding to the upper end of the vertical members I], thus forming a continuous closed loop of the vertical members I I which are, as stated, formed of a single piece of wire bent into a U-shape. Secured by welding to the top loop l9 are a series of sinuous wires or rods 24 arranged so as to form a series of staggered apertures; in this instance two series, since three of the sinuous wires 24 are used. The staggered pockets are indicated at 25. The result of this structure is to provide places where eggs can be inserted lying in the spaces 25, and resting on the rods 23.

At the bottom of the structure, transverse wires or rods 26 have their ends fixed to the U-shaped upright members l1 and are spaced at suitable intervals in a series from the rear corner, along the bottom and up around the front sides of these members l1, so that these bottom wires or rods 26 thus form a bottom pocket-shaped shelf 21.

Fixed to the back wall 8 of the recess I are upwardly opening hook-shaped holders 2!, as here shown four in number, so located that when the rear sides of two of the additional or lower shelf loop members l9, as here shown the second and fourth from the bottom, fit down into these holders 28, the shelf structure or unit will hang in the recess 1 with its top and bottom spaced from the top wall l0 and bottom wall ll of the niche. Each holder 21 preferably has a backwardly bent upper lip part, and is resilient, so that this lip part springs firmly over the wire or rod of the respective loop member IS. The structure is thus firmly held, yet may be readily removed from the niche I, for cleaning of the structure and of the interior of the recess.

The bottom of the structure is spaced up from the bottom wall ll of the recess sufiiciently to permit ample ventilation of the contents of the bottom shelf or pocket 21. The top of the structure is spaced down from the top wall I. of the recess sufficiently to permit ready access to the top shelf or pocket 22 for placing therein and removing therefrom the contents thereof.

The intermediate shelves formed by the members I! and their rods or wires 20 are suitable for storage of any articles, and being fiat, serve to support vessels such as bottles or cans. The top and bottom pocket-shaped shelves 22 and 21 are more especially convenient for storage of such articles as eggs, fruit and the like; the compartments being well adapted to receive spherically shaped articles and prevent them from rolling about. The pocket shape of these shelves 22 and 21 and the guards 2| of the intermediate shelves are adapted to insure against accidental displacement of the stored contents as the door is opened,

and closed.

It will be seen that by our improvement the utility of a refrigerator is greatly enhanced, due

to the easy access to smaller articles stored on the door instead of scattered among larger articles in the body of the refrigerator, whether on a door with a recess as described, or not. Also the capacity of the refrigerator is increased, when the recess is provided, as to quantity of articles stored; and in any case, as to refrigerating effect, since the articles are exposed apart from the articles stored in the body and the refrigerating air currents have considerably freer access thereto. The shelving, constructed as a unit, is readily removable as a unit, for cleaning of the shelving and the door. It is extremely light but rigid and durable. It thus serves its purpose without adding undue weight to the door or complicating and increasing the cost of the refrigerator.

The rods or wires are preferably of steel and fixed together bywelding, the whole shelf structure being tinned. The intermediate wires or rods 20, guards 2|, and all but the rear one of the bottom pocket wires or rods 26, are preferably of rectangular cross section, all of the others being round.

We prefer the construction and details thereof as shown and described, wherein the shelving is in a recess, but it will be understood that these are exemplary only, and that modifications may occur, such as use of the unit on an unrecessed door, or modifications of the details of construction of the unit. Therefore, we are not limited to the precise disclosure herein, but what we claim as new and desire to secure by Letters Patent, is:-
