Abstract: A track assembly for securing to a wall and receiving shelves. The track assembly includes an elongated strip which is U-shaped in lateral cross section to provide two spaced parallel legs in a connecting portion. Supports are attached to the strip for receiving shelves thereon. There is also provided a shim having a base with a top and bottom surface, the bottom surface contacts the wall and each of two parallel sides of the shim has a step, said steps being spaced apart a distance equal to the distance of the spaced parallel legs of the strip and the other two parallel sides of the shim being unstepped and spaced apart from each other a distance greater than the distance of the spaced parallel legs of the strip.

Abstract: A shelf assembly particularly adapted for use in a household refrigerator comprises a cantilever supported frame and a sliding shelf which may easily be removed from the frame. The frame includes a pair of shelf guides or tracks which, in a preferred embodiment of the invention, are inwardly extending horizontal flanges attached to frame side members. The shelf includes a pair of shelf side members which are slidably supported on the cooperating upper surfaces of the horizontal flanges. Attached near the rear corners of the shelf are outwardly extending projections which ride against the lower surfaces of the flanges to prevent the rear of the shelf from moving upwardly. A stop prevents the shelf from being pulled out farther than the extended position.
