10 Claims.

to fit the cabinet with which it is used.

A further object of our invention is to provide a sliding shelf which will not tilt and which can- I not be accidentally withdrawn entirely from the cabinet, but which can be readily removed therefrom when it is desired.

A still further object of our invention is to provide a sliding shelf having open and accessible sliding joints of such construction that the shelf can be readily cleaned and removed from its support for cleaning if desired.

Further objects and advantages of our invention will become apparent from the following de scription referring to the accompanying drawing and the features of novelty which characterize our invention will be pointed out with particularity in the claims appended to and forming a part of this specification.

In the drawing, Fig. 1 is a perspective view of part of a refrigerator cabinet containing a shelf embodying our invention, the shelf being partly pulled out; Fig. 2 is a perspective view of the shelf and supporting frame more clearly showing the detail construction and their assembled relation; Fig. 3 is an enlarged detail side elevation of the stop on the frame and the retaining end of the shelf, showing them in position for sliding the shelf off of the frame and the dotand'dash view shows them in their normal horizontal position; and Fig. 4 is a view on the line 4-4 of Fig. 3.

Referring to the drawing, we have shown a refrigerator cabinet made of inner and outer steel shells l and 2 respectively and having heat insulating material 3 between them. A door opening 4 is provided somewhat narrower than the spacing of the side walls, and a door 5 is hinged at 6 to the cabinet.

In accordance with our invention, the shelf is slidably supported on a frame sothat the shelf can be partly withdrawn from the cabinet or placed entirely within the cabinet, in which position the door can be closed. The frame is substantially rectangular in shape, and includes longitudinally extending bars '1 welded or otherwise connected at the front and back thereof by bars 8 and 9, respectively. The bars 8 and 9 extend slightly beyond the connections with the longitudinal bars I and have inturned ends forming integral transverse arms Ill, which rest on supports H. These supports preferably are pressed out of the metal inside walls of the cabinet and have upwardly presented bearing surfaces so as to support the frame and. shelf in the cabinet.

The back of the cabinet is provided with abutments l2 pressed out of the inner metal wall at such a height that the downwardly presented bearing surfaces thereof fit snugly over the bar Sso as to secure the supporting frame in place within the cabinet, thereby preventing it from tipping forward when the shelf is slid out of the cabinet. The longitudinal bars 1 are formed with upwardly extending bent portions i3, more clearly shown in Fig. 3, which serve as stops to limit the outward movement of the sliding shelf. Just forward of the bent portions 23, thebars 7 are formed with inturned sections M and are. attached to the bar 8 adjacent the ends of the inturned portions. When the frame is placed in the cabinet with the bar 9 under the projection H I2 and the arms l0 resting on the projections It the bar 8 of the frame is in close contact with the inside of the front walls of the cabinet about the door opening so that the frame is securely retained in place and will not tilt forward when the sides or other causes, and consequently it is very desirable that a standard shelf shall be readily adjustable to fit the particular cabinet with which it is used. The position of the abutments II and. I2 may also vary slightly and in order to have a good fit of the shelf within the L cabinet some adjustment to take care of these variations must be provided. We accomplish this by bending the transverse arms In of the frame in or out to adjust for the dimensions of the side walls, and up or down to adjust for inaccuracies in the positions of the abutments H and H2. The inturned portions M may be bent to adjust for inaccuracies in the dimensions from front to rear of the interior of the cabinet. readily adjusted to accurately fit the interior of the cabinet insuring a firm, stable support on which the shelf can conveniently be slid outwardly to remove, or place articles within the refrigerator cabinet.

The sliding shelf includes a framework com- Thus the frame is prising a bar I5 bent into U-shape and joined at the ends to a transverse bar IS, the shelf being of such size that it can be slid entirely within the cabinet, in which position the door can be closed. A reinforcing bar I! joins the sides I8 of the U-shaped bar l5 of the shelf, and articles are supported thereon by a grid formed by a plurality of wires I 9 welded or otherwise secured to the bars l5, l6 and H. To prevent articles on the shelf from falling off of the shelf or being knocked against the front walls of the cabinet some of these wires are looped into upwardly extending portions 20 and 2| at the front and back of the shelf, respectively, and upwardly extending sides 22 are formed of wires welded or otherwise secured to the sides l8. The front loops 20 also form convenient handles for sliding the shelf out or into the cabinet. In order to slidably and removably support the shelf on the frame the ends of the bar It are formed into inwardly turned open loops or hooks 23 which fit on the longitudinal bars 1 of the supporting frame. As shown in Figs. 3 and 4 these ends are formed so that the loops are considerably larger than the bars I but are vertically inclined to the axis of the bars so that the sides of the loops are in contact with the bars to provide a snug sliding fit thereon when the shelf is in a horizontal position. When the shelf is withdrawn from the cabinet the loops 23 engage the bent portions I3 of the frame so as to limit the outward movement of the shelf.

The connections of the elements of the unitary shelf and frame constructions are all made with welded joints and the simple arrangement and adjustment of the various parts gives a very practical combination which can be very easily and cheaply produced.

When it is desired to clean the shelf or for any other reason to remove it from the cabinet, it is slid outwardly from the cabinet until the hooked portions 23 are near the upwardly bent stops Hi. It is then tilted by raising the front upwards so that the back portion is in the position shown in full lines in Fig. 3. This places the open loops 23 coaxial with bars I so that they can be readily slid over the stops l3 and ofi at the inturned portions I 4, the open inward end of the loops or hooks 23 permitting their easy removal in this manner. Thus the open loops 23 of the shelf engaging the simple bar frame gives a construction which is readily separable and all parts of which are easily accessible for cleaning. When it is desired to clean the entire shelf structure or the interior of the cabinet, the supporting frame may be readily removed from the cabinet by lifting the front part enough to slide the bar 9 from under the abutments l2 on the rear wall of the cabinet. The frame is then tilted sidewise in the cabinet and is withdrawn in this position through the doorway 4.

Modifications of our invention, which we have illustrated and described, will occur to those skilled in the art. We desire it to be understood, therefore, that our invention is not to be limited to the particular arrangement disclosed, and we intend in the appended claims to cover all modifications which do not depart from the spirit and scope of our invention.
