March 28, 1967 w. s. PATTISON CANTILEVER SLIDE-OUT SHELF 2 Sheets-Sheet 1 Filed April 1, 1966 FIG 3 INVENTOR.

WESLEY s. PATTtSON BYWZ/ ms ATTORNRY United States Patent 3,311,072 CANTILEVER SLIDE-OUT SHELF Wesley S. Pattison, Louisville, Ky., assignor to General Electric Company, a corporation of New York Filed Apr. 1, 1966, Ser. No. 539,447 3 Claims. (l. 108-143) The present invention relates to shelves for cabinets and is more particularly concerned with a vertically adjustable cantilever supported sliding shelf structure for refrigerator cabinets and the like.

A general object of the present invention is to provide a shelf structure for refrigerator cabinets and the like in which the advantages of cantilever support, vertical adjustability, and horizontal slidability are combined in a shelf structure which is also characterized by a pleasing and attractive appearance.

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

In accordance with the illustrated embodiment of the present invention, there is provided a vertically adjustable cantilever supported sliding shelf structure comprising a generally rectangular frame on which a shelf is slidably mounted. The frame includes longitudinally extending sheet metal side members having inwardly extending shelf supporting flanges at the bottom edge thereof, a plurality of cross bars interconnecting the side members adjacent the front and rear ends thereof and means for cantilever supporting the frame for vertical adjustment within a cabinet. The storage shelf slidably supported on the frame for movement between "a normal and an extended position in cludes a shelf guard extending upwardly from the rear edge thereof while the frame includes a decorative strip supported on one of the rear cross bars in a position such that it is in overlapping relationship with the upper edge of the shelf guard when the shelf is in its recessed position thereby providing a shelf structure having a sturdy and pleasing appearance due largely to the portions of the frame side members and the shelf guard and decorative strip extending upwardly above the storage area of the shelf.

For a better understanding of the invention reference may be had to the accompanying drawing in which:

FIGURE 1 is a side elevational view, partly in section, of a portion of a refrigerator cabinet including the shelf structure of the present invention;

FIGURE 2 is a view similar to FIGURE 1 with the shelf in extended position;

FIGURE 3 is a sectional view of the shelf structure of FIGURE 1 taken generally along line 3-3 of FIG- URE 1;

FIGURE 4 is a perspective view of a portion of the shelf structure of the present invention; and

FIGURE 5 is a sectional view taken generally along line 5--5 of FIGURE 2.

With reference to FIGURE 1 of the drawing there is shown a refrigerator cabinet including a liner 1 forming a storage compartment within the cabinet, the access opening to which is closed by a door 2. Spaced from each vertical rear corner 3 of the liner 1 and secured to the rear liner wall 4 are horizontally spaced vertically extending supports 5 (only one of which is shown) each of which includes a forwardly extending flange portion 6 shaped to provide a plurality of vertically spaced hooks 7 separated by coplanar bearing surfaces 8.

The Shelf structure also includes a generally rectangular frame adapted to be cantilever supported on the supports 6. The frame 10 is of a generally rectangular shape and 3,311,072 Patented Mar. 28, 1967 includes opposed longitudinally extending sheet metal side members 11 each having an inwardly extending horizontal flange 12 at the bottom edge thereof. The side members 11 are interconnected by a plurality of cross bars including a front cross bar 14, a lower rear cross bar 15 and an upper rear cross bar 16, the upper rear cross bar 16 being above and spaced fom the lower rear cross bar 15.

Means for supporting the frame on the supports '5 comprise an L-shaped rod 20 at each corner of the frame adjacent the upper cross bar 16. As is shown more particularly in FIGURE 4 of the drawing these L-shaped rods 20 include a transverse arm 21 secured to the adjacent portion of one of the side members 11 rearwardly of the cross bar 16 and a second arm 22 secured to an adjacent portion ofthe cross bar 16. The transverse arm 21 is so positioned relative to the rear edge 24 of the slide 12 that when the transverse arm 21 is supported on one of the hooks 7, the rear edge 24 of the flange 12 of each side member 11 bears against one of the plane surfaces 8 on the support 5. By providing a plurality of vertically spaced hooks 7, the frame 10 may be supported in any of a plurality of vertically spaced positions within the cabinet.

A wire shelf generally indicated by the numeral 27 is slidably supported on the frame 10 for movement between a normal or recessed position within the cabinet as illustrated in FIGURE 1 of the drawing to an extended position as illustrated in FIGURE 2 of the drawing. The shelf 27 includes a generally rectangular frame 28 including side portions 29 and a plurality of longitudinally extending wires 34) secured to the frame to provide a supporting surface for articles stored on the shelf. A relativelyheavy rod-like cross member 31 extends transversely of the shelf near the central portion thereof for strengthen-- ing the wires 30. The shelf 27 also includes depending legs 33 including end portions 34 adapted to be slidably supported on the flanges 12 while the forward portion of the shelf 27 is supported on Nylon combination slide and guide members 36 snapped onto the forward cross bar 14 adjacent each end thereof and including channels 37 for receiving the respective side members 29. As is shown in FIGURE 5, the upwardly extending inner side wall 38 of each of the Nylon members 36 provides stop means adapted to be engaged by the central cross bar 31 and stop forward travel of the shelf as it is moved to its extended position.

A11 upwardly extending sheet metal guard 40 is secured along the entire rear edge of the shelf 27, the purpose of this guard being two-fold; one,to prevent articles stored when the shelf is moved to its extended position and the other to provide a pleasing and decorative appearance to the shelf structure in cooperation with a decorative strip generally indicated by the numeral 41 and supported on the rear portion of the frame 10.

More specifically, the decorative strip 41 which extends between the opposed side members 10 of the frame has its upper edge 42 formed to slip over and hook onto the upper cross bar 16 and its lower edge 43 bent rearwardly and adapted to snap onto pins 44 provided on each of the side members 10.

The vertical dimensions of the decorative strip 41 are such that when the shelf 27 is in its recessed position as illustrated in FIGURE 1 of the drawing, the strip 41 is positioned slightly rearwardly of the shelf guard 40 with the upper edge of the shelf guard 40 in overlapping relationship with the lower edge 43 of the strip 41. In these relative positions the decorative strip 41 and the guard 40 give the appearance of a relatively solid generally continuous guard structure at the rear of the shelf structure while the portions of the side members 10 extending upwardly above the shelf 27 continue this solid appearance about the two sides of the shelf.

While there has been shown and described a specific embodiment of the present invention, it is to be understood that it is not limited thereto and is intended by the appended claims to cover all such changes and modifications as fall Within the true spirit and scope of the invention.

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

1. A cantilever-supported sliding shelf structure comprising:

a generally rectangular frame including longitudinally extending sheet metal side members each having an inwardly extending horizontal flange at the bottom edge thereof,

a plurality of cross bars interconnecting said side members including a front cross bar and a lower rear cross has above and spaced from said flanges and an upper rear cross bar above and spaced from said lower rear cross bar,
