Abstract

Shelf brackets to conduct electricity to refrigerator shelves are disclosed. An example shelf bracket includes an end configured to engage a support rail, the end having a first area to conduct electricity from the support rail to the shelf bracket, an arm extending from the end to support the shelf, the arm comprising a second area to conduct electricity from the shelf bracket to the shelf, a non-electrically conductive coating applied to substantially all of the shelf bracket except in the first and second areas, a first electrically conductive material applied to at least a portion of the first area, and a second electrically conductive material applied to at least a portion of the second area, wherein the shelf bracket is formed from a third electrically conductive material, the third electrically conductive material to conduct electricity between the first and second areas.

First claim

The invention claimed is:

1. A refrigerator comprising:
a compartment;
a shelf;
a shelf bracket configured to support and conduct electricity to the shelf within the compartment of the refrigerator, the shelf bracket including:
a first area configured to engage a support rail and conduct electricity from the support rail to the shelf bracket, wherein the first area is part of an end of the shelf bracket, the end is configured to extend into an opening or slot defined in the support rail, and the first area is configured to engage an edge of the opening or slot;
a second area configured to conduct electricity from the shelf bracket to the shelf;
a third area configured to engage the support rail and conduct electricity from the support rail to the shelf bracket, wherein the third area is part of the end of the shelf bracket, and the third area is configured to engage a back side of the support rail; and
a non-electrically conductive coating applied to substantially all of the shelf bracket except in the first, second and third areas, wherein the shelf bracket is formed from a first electrically conductive material and is configured to conduct electricity between the first and second areas.

2. The refrigerator of claim 1 , further comprising:
an electrically conductive coating applied to at least a portion of at least one of the first and second areas.

3. The refrigerator of claim 1 , further comprising:
a second electrically conductive material applied to at least a portion of at least one of the first and second areas.

4. The refrigerator of claim 3 , wherein the second electrically conductive material comprises an adhesive, a plastic or a plating.

5. The refrigerator of claim 4 , wherein the first electrically conductive material comprises a steel or a combination of nickel and tin.

6. The refrigerator of claim 3 , wherein the second electrically conductive material is configured to reduce or prevent corrosion of the shelf bracket.

7. A shelf bracket configured to support and conduct electricity to a shelf of a refrigerator, the shelf bracket comprising:
a first area configured to engage a support rail and conduct electricity from the support rail to the shelf bracket, wherein the first area is part of an end of the shelf bracket, the end is configured to extend into an opening or slot defined in the support rail, and the first area is configured to engage an edge of the opening or slot;
a second area configured to conduct electricity from the shelf bracket to the shelf;
a third area configured to engage the support rail and conduct electricity from the support rail to the shelf bracket, wherein the third area is part of the end of the shelf bracket, and the third area is configured to engage a back side of the support rail; and
a non-electrically conductive coating applied to substantially all of the shelf bracket except in the first, second and third areas, wherein the shelf bracket is formed from a first electrically conductive material and is configured to conduct electricity between the first and second areas.

8. The shelf bracket of claim 7 , further comprising:
an electrically conductive coating applied to at least a portion of at least one of the first and second areas.

9. The shelf bracket of claim 7 , further comprising:
a second electrically conductive material applied to at least a portion of at least one of the first and second areas.

10. The shelf bracket of claim 9 , wherein:
the second electrically conductive material is applied to at least a portion of the first area;
a third electrically conductive material is applied to at least a portion of the second area; and
the third electrically conductive material is different from the second electrically conductive material.

11. The shelf bracket of claim 9 , wherein the second electrically conductive material comprises an adhesive, a plastic or a plating.

12. The shelf bracket of claim 11 , wherein the first electrically conductive material comprises a steel or a combination of nickel and tin.

13. The shelf bracket of claim 9 , wherein the second electrically conductive material is configured to reduce or prevent corrosion of the shelf bracket.

14. The shelf bracket of claim 7 , wherein the non-electrically conductive coating is configured to reduce or prevent corrosion of the shelf bracket.

15. The shelf bracket of claim 7 , wherein the non-electrically conductive coating comprises a plastic or a paint.

16. The shelf bracket of claim 7 , wherein the second area is configured to conduct electricity from the shelf bracket to a lighting unit or a user interface of the shelf.

17. The shelf bracket of claim 7 , further comprising:
an electrically conductive coating applied to at least a portion of at least one of the first and third areas.

18. The shelf bracket of claim 7 , further comprising:
a second electrically conductive material applied to at least a portion of at least one of the first and third areas.

19. The shelf bracket of claim 18 , wherein the second electrically conductive material comprises an adhesive, a plastic or a plating.

20. The shelf bracket of claim 18 , wherein the second electrically conductive material is configured to reduce or prevent corrosion of the shelf bracket.
