Abstract

An adjustable shelf for a refrigerator includes a first and a second shelf portion being slidably moveable between extended and retracted positions. A frame includes a main track that guides the second shelf portion. An auxiliary external track is disposed on an extended lower edge of the frame, following the main track. A hook member is attached to and protrudes downwards from the second shelf portion, the hook member engaging with and sliding along the auxiliary external track to minimize lateral movement of a front end of the second shelf portion as the second shelf portion is slidably moved. In another embodiment, a freezer drawer assembly comprises first and second storage baskets. The second storage basket comprises front roller members that are seated on the first storage unit and are guided along a primary track by parallel, opposing track sidewalls.

First claim

The invention claimed is:

1. A refrigerator with an adjustable shelf comprising:
a food compartment with a rear wall and a door configured to provide access to the food compartment; and
an adjustable shelf for storing food items within the food compartment, the adjustable shelf attached to the rear wall and comprising:
a first shelf portion for supporting food items thereon, comprising a first planar support surface that is arranged normal to the rear wall;
a second shelf portion for supporting food items thereon, comprising a second planar support surface, the second shelf portion being slidably moveable relative to the first shelf portion between an extended position and a retracted position, wherein at the extended position, the second shelf portion is arranged relative to the first shelf portion such that the second planar support surface is substantially coplanar with the first planar support surface, and wherein at the retracted position, a majority of the second planar support surface is arranged subjacent to the first planar support surface;
a frame configured to support the first and the second shelf portions, wherein the frame includes two opposed side arms that each include a main track that guides the second shelf portion as the second shelf portion is slidably moved between the extended and retracted positions;
an auxiliary external track disposed on an extended lower edge of the frame, the auxiliary external track following the main track; and
a hook member attached to and protruding downwards from the second shelf portion, the hook member engaging with and sliding along the auxiliary external track to minimize lateral movement of a front end of the second shelf portion as the second shelf portion is slidably moved between the extended and retracted positions.

2. The refrigerator with an adjustable shelf of claim 1 , wherein the auxiliary external track comprises a planar wall.

3. The refrigerator with an adjustable shelf of claim 1 , wherein the auxiliary external track is an extension of an interior sidewall of the frame.

4. The refrigerator with an adjustable shelf of claim 1 , wherein the main track comprises a ramped, front drop down channel and a horizontal section, and
wherein the auxiliary external track has a ramped front portion that extends below and follows the front drop down channel, and a horizontal portion that follows along the horizontal section of the main track.

5. The refrigerator with an adjustable shelf of claim 1 , wherein the hook member has a “J”-shaped geometry.

6. The refrigerator with an adjustable shelf of claim 5 , wherein the hook member comprises an interior arm that extends downwardly from the second shelf portion, an exterior arm, and a projecting guide interconnected between the interior and exterior arms.

7. The refrigerator with an adjustable shelf of claim 6 , wherein the second shelf portion comprises a body that supports the second planar support surface, and the interior arm extends downwardly from the body.

8. The refrigerator with an adjustable shelf of claim 6 , wherein the guide has a width slightly wider than a thickness of the auxiliary external track so that the auxiliary external track is captured between the interior and exterior arms.

9. The refrigerator with an adjustable shelf of claim 1 , wherein the main track further comprises a hole extending therethrough to disengage the hook member from the auxiliary external track.

10. The refrigerator with an adjustable shelf of claim 9 , wherein the hole is located is immediately beyond a terminal end of the auxiliary external track.

11. The refrigerator with an adjustable shelf of claim 9 , wherein the hole is of sufficient size to enable the hook member to completely pass through the main track.

12. The refrigerator with an adjustable shelf of claim 9 , wherein the first shelf portion is pivotally connected to the frame and, in the retracted position, the second shelf portion is coupled to the first shelf portion so that first and second shelf portions can be rotated upwards as a single unit.

13. The refrigerator with an adjustable shelf of claim 12 , wherein the hook member passes without obstruction vertically upwards through the hole in the main track when the first and second shelf portions are rotated upwards.

14. The refrigerator with an adjustable shelf of claim 1 , further comprising a pair of auxiliary external tracks disposed one each on the opposed side arms of the frame, and a pair of hook members disposed one on each side of the second shelf portion that are engaged with and ride along the auxiliary external tracks on both opposed side arms.
