Abstract

A refrigerator appliance having one or more sliding shelves. The sliding shelf may slide along one or more tracks. The sliding shelf may include one or more shelf plates. The one or more tracks may be adjustable.

First claim

The invention claimed is:

1. A refrigerator appliance comprising:
a housing defining at least one compartment;
at least one door attached to the housing and defining at least a portion of the at least one compartment;
a pair of tracks positioned within the housing;
at least one sliding shelf positionable within the at least one compartment of the housing, wherein the at least one sliding shelf includes a top surface and a bottom surface, wherein the at least one sliding shelf slides between a stowed position and a deployed position along the pair of tracks, and wherein the deployed position is different from the stowed position;
the at least one sliding shelf includes a plurality of shelf plates spaced for a distance from each other in a direction of sliding between the stowed position and the deployed position
wherein the at least one sliding shelf includes a plurality of links interconnecting the plurality of shelf plates to each of the pair of tracks, wherein two opposing links of the plurality of links on the respective pair of tracks receives an end of at least one of the plurality of shelf plates, respectively; and
a through opening extending from the bottom surface to the top surface of the at least one sliding shelf, wherein the through opening of the at least one sliding shelf includes an outer periphery defined by a first shelf plate of the plurality of shelf plates, followed by at least one first link of the plurality of links, followed by a second shelf plate of the plurality of shelf plates, followed by at least one second link of the plurality of links, before returning back to the first shelf plate.

2. The refrigerator appliance of claim 1 further comprising a plurality of biased locks fixing the position of the at least one sliding shelf in at least the deployed position.

3. The refrigerator appliance of claim 1 wherein the plurality of shelf plates are spaced from each other when in both the stowed position and the deployed position.

4. The refrigerator appliance of claim 1 wherein the at least one sliding shelf includes a plurality of rollers to engage the pair of tracks, the plurality of rollers slide at least a portion of the at least one sliding shelf from a horizontal orientation in the deployed position to a vertical orientation when in the stowed position.

5. The refrigerator appliance of claim 1 wherein the plurality of shelf plates are spaced from each other for the distance for an entire length between the two opposing links.

6. A sliding shelf slidably engaging two tracks defining a path for the sliding shelf within a refrigerator appliance comprising:
a first shelf plate;
a second shelf plate;
a plurality of links slidably engaging the first shelf plate and the second shelf plate to the two tracks between a deployed position and a stowed position, wherein the deployed position is different from the stowed position; and
the plurality of links space the first shelf plate away from the second shelf plate for a distance to create a through opening, wherein an outer periphery of the through opening is defined by a lateral edge of the plurality of links, a lateral edge of the first shelf plate, and a lateral edge of the second shelf plate.

7. The sliding shelf of claim 6 wherein a first link of the plurality of links includes a cradle receiving one end of the first shelf plate.

8. The sliding shelf of claim 7 wherein a second link of the plurality of links includes a cradle receiving an end of the second shelf plate.

9. The sliding shelf of claim 8 further comprising one or more shafts extending from one or more rollers, wherein each of the first link and the second link of the plurality of links includes a through opening receiving the one or more shafts.

10. The sliding shelf of claim 9 wherein the one or more shafts therein allowing the first shelf plate and the second shelf plate to pivot relative to each other.

11. The sliding shelf of claim 6 wherein the through opening extends along the first shelf plate for an entire length between the plurality of links spacing the first shelf plate away from the second shelf.

12. The sliding shelf of claim 6 wherein the plurality of links include a through opening receiving a shaft therein allowing the first shelf plate and the second shelf plate to pivot relative to each other.

13. The sliding shelf of claim 6 further comprising one or more locking mechanisms fixing the position of the sliding shelf relative to a pair of tracks.

14. The sliding shelf of claim 13 wherein the one or more locking mechanisms is a biased rocker arm positioned on a track of the pair of tracks to fix the position of the sliding shelf relative to the pair of tracks.

15. A refrigerator appliance comprising:
a housing defining at least one compartment;
at least one door attached to the housing and defining at least a portion of the at least one compartment;
at least one pair of tracks positioned within the housing;
at least one sliding shelf positionable within the at least one compartment of the housing, wherein the at least one sliding shelf includes a top surface and a bottom surface, wherein the at least one sliding shelf slides between a stowed position and a deployed position along the pair of tracks, and wherein the deployed position is different from the stowed position;
the at least one sliding shelf includes a first shelf plate and a second shelf plate spaced from each other by a plurality of links coupling the at least one sliding shelf to the at least one pair of tracks;
the first shelf plate, the second shelf plate, and the plurality of links define a through opening extending from the bottom surface to the top surface of the at least one sliding shelf.

16. The refrigerator appliance of claim 15 wherein the through opening of the at least one sliding shelf includes an outer periphery defined by the first shelf plate, followed by at least one first link of the plurality of links, followed by the second shelf plate, followed by at least one second link of the plurality of links, before returning back to the first shelf plate.

17. The refrigerator appliance of claim 15 wherein the at least one sliding shelf includes a plurality of rollers slidably engaging the at least one pair of tracks between the stowed position and the deployed position.

18. The refrigerator appliance of claim 15 further comprising one or more locking mechanisms to fix the position of the at least one sliding track.

19. The refrigerator appliance of claim 15 wherein each one of adjacent links of the plurality of links slidably engaging a track of the at least one track include a cradle receiving an end of the first shelf plate and the second shelf plate, respectively.

20. The refrigerator appliance of claim 15 further comprising two sliding shelves of the at least one sidling shelf slidably engaging one track of the at least one pair of tracks.
