Metal rack for an oven appliance

1. A rack for an oven appliance, the rack comprising:

a metal sheet comprising a plurality of openings spaced over the metal sheet between multiple peripheral edges that are coplanar with the metal sheet;

a frame comprising a pair of L-shaped portions attached along opposing peripheral edges of the metal sheet, each L-shaped portion comprising a pair of legs that are respectively horizontally-oriented and vertically-oriented, each of the pair of legs defining a slot, wherein the opposing peripheral edges of the metal sheet extend into the slot along only the horizontally-oriented leg, and wherein each L-shaped portion is positioned such that the horizontally-oriented leg extends further away from a center of the metal sheet than a vertical plane associated with the vertically-oriented leg, such that the respective peripheral edge of the metal sheet that extends along the horizontally-oriented leg of each L-shaped portion extends beyond the vertically-oriented leg;

a brace positioned adjacent to the metal sheet, connected with the frame, and extending between at least two of the multiple peripheral edges of the metal sheet.

2. The rack for an oven appliance as in claim 1 , wherein for each L-shaped portion the pair of legs are orthogonal to each other.

3. The rack for an oven appliance as in claim 2 , wherein the oven appliance includes guides positioned along opposing interior walls, wherein each L-shaped portion is configured for receipt of one of the guides between the pair of legs of each L-shaped portion.

4. The rack for an oven appliance as in claim 1 , wherein the metal sheet comprises an expanded metal.

5. The rack for an oven appliance as in claim 4 , wherein the openings of the metal sheet are diamond shaped.

6. The rack for an oven appliance as in claim 1 , wherein the frame comprises multiple frame portions, each of the frame portions being attached to at least one peripheral edge of the metal sheet.

7. The rack for an oven appliance as in claim 1 , wherein the frame portions and the metal sheet are welded together.

8. The rack for an oven appliance as in claim 1 , wherein the frame comprises multiple frame portions, and wherein each frame portion is L-shaped and defines a slot into which at least one peripheral edge is received.

9. The rack for an oven appliance as in claim 8 , wherein the frame portions and the sheet are welded together.

10. The rack for an oven appliance as in claim 1 , wherein the brace includes one or more tabs positioned at opposing ends of the brace, the tabs being connected to the frame.

11. The rack for an oven appliance as in claim 10 , wherein the tabs are welded to the frame.

12. The rack for an oven appliance as in claim 1 , wherein the frame comprises multiple frame portions, and wherein at least one of the frame portions is angled relative to the other frame portions so as to provide a stop that delimits the sliding movement of the rack within the oven appliance.

13. The rack for an oven appliance as in claim 1 , wherein the metal sheet is coated with a metal plating material.

14. The rack for an oven appliance as in claim 1 , wherein the metal sheet has an open area of about 80 percent or greater.

15. The rack for an oven appliance as in claim 1 , wherein the metal sheet is coated with a non-metallic, ceramic material.

16. An oven comprising the rack of claim 1 .

17. A method for manufacturing an oven rack, comprising:

cutting an expanded metal sheet into a predetermined shape for the oven rack, the metal sheet having multiple peripheral edges lying within a plane defined by the metal sheet;

creating a frame for attachment to the periphery of the expanded metal sheet, the frame comprising an L-shaped portion that includes a pair of legs that are respectively horizontally-oriented and vertically-oriented, each of the pair of legs defining a slot; and

inserting at least one peripheral edge of the expanded metal sheet into only the slot defined by the horizontally-oriented leg such that the at least one peripheral edge of the expanded metal sheet remains within the plane of the metal sheet and the vertically-oriented leg is positioned beneath the metal sheet, wherein each L-shaped portion is positioned such that the horizontally-oriented leg extends further away from a center of the metal sheet than a vertical plane associated with the vertically-oriented leg.

18. A method for manufacturing an oven rack as in claim 17 , further comprising the step of coating the expanded metal sheet with a non-metallic material, a metallic material, or a combination thereof.

19. A rack for an oven appliance, the rack comprising:

a metal sheet having a plurality of openings spaced over the sheet, the sheet having multiple peripheral edges lying within a plane defined by the metal sheet;

a frame attached to at least one peripheral edge of the metal sheet such that the at least one peripheral edge is within the plane of the metal sheet, wherein the frame comprises multiple frame portions, and wherein at least one frame portion is L-shaped and includes a slot defined by a first horizontally-oriented leg and a second vertically-oriented leg, wherein the metal sheet is positioned outside of the second vertically-oriented leg and within a portion of the slot defined by the first horizontally-oriented leg, wherein the L-shaped portion is positioned such that the first horizontally-oriented leg extends further away from a center of the metal sheet than a vertical plane associated with the second vertically-oriented leg, and wherein the portion of the metal sheet positioned within the slot defined by the first horizontally-oriented leg extends beyond the second vertically-oriented leg; and

a brace positioned adjacent to the metal sheet, connected with the frame, and extending between at least two of the peripheral edges of the metal sheet.

20. The rack for an oven appliance as in claim 19 , wherein the metal sheet comprises an expanded metal.
