Abstract

A rack assembly for an appliance includes a geared rack and a pair of gears. The gears of the pair of gears mesh with each other and the geared rack. The rack assembly also includes a shelf and a support link that couples that shelf to at least one of the pair of gears. The geared rack and pair of gears can assist with selectively adjusting a vertical height of the shelf.

Claims

1. A rack assembly for an appliance, the rack assembly defining a lateral direction and a vertical direction, the lateral and vertical directions being perpendicular to each other, the rack assembly comprising:

a shelf for supporting food items and cooking utensils;

a geared rack that extends along the lateral direction;

a pair of gears positioned adjacent the geared rack, the gears meshing with each other and the geared rack;

an actuator assembly configured for selectively disengaging at least one gear of the pair of gears from the geared rack; and

a support link extending between and coupling at least one of the pair of gears to the shelf.

2. The rack assembly of claim 1, further comprising a coupling link extending between and coupling the gears together such that the gears mesh with each other.

3. The rack assembly of claim 1, wherein the support link is rotatably mounted to the at least one of the pair of gears and to the shelf.

4. The rack assembly of claim 1, wherein the shelf is a first shelf, the rack assembly further comprising a second shelf spaced apart from the first shelf along the vertical direction, the geared rack mounted to the second shelf.

5. The rack assembly of claim 4, further comprising a slide assembly having a fixed portion and a sliding portion that is movable along the lateral direction relative to the fixed portion, the second shelf mounted to the sliding portion of the slide assembly.

6. The rack assembly of claim 1, further comprising a pair of bracing links and a mounting feature, the geared rack coupled to the mounting feature, the links of the pair of bracing links coupling the shelf to the mounting feature.

7. The rack assembly of claim 6, wherein the links of the pair of bracing links are rotatably mounted to the mounting feature and the shelf in order to couple the mounting feature to the shelf.

8. The rack assembly of claim 6, wherein the shelf is a first shelf and the mounting feature is a slide assembly, the rack assembly further comprising a second shelf spaced apart from the first shelf along the vertical direction, the geared rack mounted to the second shelf, the slide assembly having a fixed portion and a sliding portion that is movable along the lateral direction relative to the fixed portion, the second shelf mounted to the sliding portion of the slide assembly.

9. The rack assembly of claim 1, further comprising a clip mounted to the support link and coupling the support link to the shelf.

10. The rack assembly of claim 1, wherein the actuator assembly comprises:

a handle rotatably mounted to the shelf; and

a connector link extending between and coupling the at least one gear of the pair of gears to the handle.

11. An appliance, the appliance defining a vertical direction, a lateral direction, and a transverse direction, the vertical, lateral, and transverse directions being mutually perpendicular, the appliance comprising:

a cabinet having interior walls that define a chamber, the interior walls of the cabinet including sidewalls spaced apart from each other along the transverse direction;

a shelf assembly positioned within the chamber of the cabinet, the shelf assembly comprising

a support feature mounted to the cabinet at one of the sidewalls of the cabinet;

a geared rack mounted to the support feature, the geared rack extending along the lateral direction;

a pairs of gears positioned adjacent the geared rack, the gears meshing with each other and the geared rack;

an actuator assembly configured for selectively disengaging at least one of the pair of gears from the geared rack;

a shelf for supporting items thereon; and

a support link coupling at least one of the pair of gears to the shelf.

12. The appliance of claim 11, wherein the shelf assembly further comprises a coupling link extending between and coupling the gears together such that the gears mesh with each other.

13. The appliance of claim 11, wherein the support link is rotatably mounted to the at least one of the pair of gears and to the shelf.

14. The appliance of claim 11, wherein the shelf is a first shelf, the shelf assembly further comprising a second shelf spaced apart from the first shelf along the vertical direction, the second shelf mounted to the support feature, the geared rack mounted to the second shelf.

15. The appliance of claim 14, wherein the support feature comprises a slide assembly having a fixed portion and a sliding portion that is movable along the lateral direction relative to the fixed portion, the second shelf mounted to the sliding portion of the slide assembly.

16. The appliance of claim 11, wherein the shelf assembly further comprises a pair of bracing links, the links of the pair of bracing links coupling the mounting feature to the shelf.

17. The appliance of claim 11, wherein the shelf assembly further comprises a clip mounted to the support link and coupling the support link to the shelf.

18. The appliance of claim 11, wherein the actuator assembly comprises:

a handle rotatably mounted to the shelf; and

a connector link coupling at least one of the pair of gears to the handle.

19. A rack assembly for an appliance, the rack assembly defining a vertical direction and a lateral direction that are perpendicular to each other, the rack assembly comprising:

a shelf for supporting food items and cooking utensils; and

a shelf adjustment assembly for supporting the shelf at various positions along the vertical direction, the shelf adjustment assembly comprising

a geared rack that extends along the lateral direction;

a pair of gears positioned adjacent the geared rack, the gears meshing with each other and the geared rack; and

an actuator assembly configured for selectively disengaging at least one of the pair of gears from the geared rack.

20. The rack assembly of claim 19, wherein the geared rack is mounted to the shelf.
