Abstract

A refrigerator appliance includes a liner defining a cavity having a back wall and opposing first and second sidewalls. An elongate shelf-support ladder is arranged vertically on the back wall and positioned centrally. A central arm has a rear portion attached to the ladder such that the arm is cantilevered from the ladder. A shelf assembly is supported by the central arm and includes a first shelf surface located between the first sidewall and the arm and a second shelf surface located between the second sidewall and the arm.

Claims (35)

1. A refrigerator appliance comprising:

a liner defining a cavity having a back wall and opposing first and second sidewalls;

an elongate shelf-support ladder arranged vertically on the back wall and positioned centrally;

a central arm having a rear portion attached to the ladder such that the arm is cantilevered from the ladder, wherein the central arm further has a top and first and second sidewalls depending from opposing sides of the top; and

a shelf assembly supported by the central arm and including:

a first rear support connected to the first sidewall of the central arm, wherein the first rear support includes a connector received on a top edge of the first sidewall of the arm,

a first shelf surface located between the first sidewall of the cavity and the arm and supported by the first rear support, wherein the second rear support includes a connector received on a top edge of the second sidewall of the arm,

a second rear support connected to the second sidewall of the central arm, and

a second shelf surface located between the second sidewall of the cavity and the arm and supported by the second rear support.

2. The refrigerator of claim 1 , wherein a first distance between the first sidewall of the cavity and the ladder is substantially equal to a second distance between the second sidewall of the cavity and the ladder.

3. The refrigerator of claim 1 , wherein the shelf assembly further includes a first pane defining the first shelf surface and a second pane defining the second shelf surface.

4. The refrigerator of claim 3 , wherein the first rear support defines a channel, and a rear edge of the first pane is received in the channel.

5. The refrigerator of claim 4 , wherein the first pane defines a groove, and the channel has a projection received in the groove to secure the first pane to the rear support.

6. The refrigerator of claim 3 , wherein the first and second panes are glass.

7. The refrigerator of claim 1 , wherein first rear support is arranged orthogonal to the arm, and the second rear support is arranged orthogonal to the arm.

8. The refrigerator of claim 1 , wherein the first rear support defines a channel that receives a rear edge of the first pane, and the second rear support defines a channel that receives a rear edge of the second pane.

9. The refrigerator of claim 1 , wherein each connector includes an anti-rotation tab configured to engage with a corresponding one of the first and second sidewalls of the arm.

10. The refrigerator of claim 1 , wherein the shelf assembly further includes a first front support connected to the first sidewall of the arm and extending toward the first sidewall of the cavity and a second front support connected to the second sidewall of the arm and extending toward the second sidewall of the cavity, wherein the first front support is connected to the first shelf surface and the second front support is connected to the second shelf surface.

11. The refrigerator of claim 1 , wherein the refrigerator appliance only includes one shelf-support ladder in the cavity.

12. The refrigerator of claim 1 further comprising a cover disposed on the back wall and defining a central slot extending vertically, wherein the ladder is disposed in the central slot.

13. A refrigerator appliance comprising:

a liner defining a cavity having a back wall and opposing first and second sidewalls, wherein the first sidewall of the liner defines a support rail;

an elongate shelf-support ladder arranged vertically on the back wall and positioned centrally;

a central arm having a rear portion attached to ladder such that the arm is cantilevered from the ladder;

a first shelf including a first planar body and a first rear support member received on a rear portion of the first planar body, the first rear support member being connected to the arm and extending therefrom towards the first sidewall, wherein the first rear support member has a connector rotatably connected to the support rail such that the first shelf is pivotal relative to the support rail, wherein the connector includes a planar portion configured to rest on top of the support rail and a hooked portion configured to partially extend around the support rail; and

a second shelf including a second planar body and a second rear support member received on a rear portion of the second planar body, the second rear support member being connected to the arm and extending therefrom towards the second sidewall.

14. The refrigerator appliance of claim 13 , wherein the second sidewall of the liner defines a second support rail, and the second rear support member has a connector rotatably connected to the second support rail such that the second shelf is pivotal relative to the second support rail.

15. The refrigerator appliance of claim 13 , wherein the first shelf further includes a first front support member received on a front portion of the first planar body, the first front support member being connected to the arm and extending therefrom towards the first sidewall.

16. A shelving system of a refrigerator appliance comprising:

an elongate shelf-support ladder configured to be arranged vertically on a back wall of a fresh-food compartment;

a central arm having a rear portion attached to ladder such that the arm is cantilevered from the ladder, wherein the central arm further has first and second opposing sidewalls and a top surface extending from the first sidewall to the second sidewall;

a first shelf including a first planar body and a first rear support member received on a rear portion of the first planar body, the first rear support member being connected to the first sidewall of the central arm, wherein the first rear support member includes a connector received on a top edge of the first sidewall of the arm; and

a second shelf including a second planar body and a second rear support member received on a rear portion of the second planar body, the second rear support member being connected to the second sidewall of the central arm.

17. The shelving system of claim 16 , wherein the second rear support member includes another connector received on a top edge of the second sidewall of the arm.

18. The shelving system of claim 16 , wherein the first rear support member includes a second connector configured to pivotally connect with a support rail of a liner of the refrigerator appliance.
