Abstract

A display case door assembly for a temperature-controlled storage device includes a vacuum panel, a hinge rail, and a lighting element. The vacuum panel includes a first vacuum pane, a second vacuum pane, and an evacuated gap between the first and second vacuum panes. The evacuated gap provides thermal insulation for the vacuum panel. The hinge rail is coupled to an edge of the vacuum panel and configured to rotate along with the vacuum panel between an open position and a closed position. The lighting element is coupled to at least one of the edge rail and the vacuum panel and configured to emit light toward an interior of the temperature-controlled storage device when the hinge rail and vacuum panel are in at least the closed position.

Claims

1. A frameless vacuum-insulated refrigerated display case door, comprising:

a hinge rail comprising a channel portion and a hinge receiving portion, the hinge receiving portion defining two openings configured to receive hinge pins for mounting the door to a refrigerated display case, the hinge rail having a rear portion arranged to face into the refrigerated display case with the door mounted to the refrigerated display case;

a vacuum-insulated glass (VIG) panel assembly comprising two panes of glass bounding a sealed evacuated space between the panes, a first edge of the VIG panel assembly disposed within the channel portion of the hinge rail, wherein other edges of the VIG panel assembly are unbounded by frame members; and

a lighting element coupled to the rear portion of the hinge rail.

2. The door of claim 1, further comprising a mounting bracket coupled to a rear portion of the hinge rail, wherein the lighting element is coupled within the mounting bracket.

3. The door of claim 2, wherein the mounting bracket comprises a wiper configured to seal the door when the door is in a closed position.

4. The door of claim 1, further comprising a wiper attached to one of the other edges of the VIG panel assembly, the wiper configured to provide a seal along an edge of the door.

5. The door of claim 1, further comprising a handle secured to the VIG panel assembly near a side opposite the first edge of the VIG panel.

6. The door of claim 1, wherein the lighting element extends along a length of the hinge rail and is substantially parallel to the channel portion.

7. The door of claim 1, wherein the lighting element extends along at least a majority of a length of the hinge rail.

8. The door of claim 1, wherein the VIG panel assembly comprises a perimeter seal bonding the panes along a perimeter of the panes.

9. The door of claim 1, wherein the VIG comprises an anti-reflective coating configured to absorb or transmit light.

10. A refrigerated display case comprising:

a frame; and

a first vacuum-insulated door and a second vacuum-insulated door mounted to the frame, each of the first vacuum-insulated door and the second vacuum-insulated door comprising;

a hinge rail comprising a channel portion and a hinge receiving portion, the hinge receiving portion defining two openings configured to receive hinge pins for mounting the door to a refrigerated display case, the hinge rail having a rear portion arranged to face into the refrigerated display case with the door mounted to the refrigerated display case;

a vacuum-insulated glass (VIG) panel assembly comprising two panes of glass bounding a sealed evacuated space between the panes, a first edge of the VIG panel assembly disposed within the channel portion of the hinge rail, wherein other edges of the VIG panel assembly are unbounded by frame members; and

a lighting element coupled to the rear portion of the hinge rail.

11. The refrigerated display case of claim 10, further comprising a mounting bracket coupled to a rear portion of the hinge rail, wherein the lighting element is coupled within the mounting bracket.

12. The refrigerated display case of claim 11, wherein the mounting bracket comprises a wiper configured to seal the door when the door is in a closed position.

13. The refrigerated display case of claim 10, further comprising a wiper attached to one of the other edges of the VIG panel assembly, the wiper configured to provide a seal along an edge of the door.

14. The refrigerated display case of claim 10, further comprising a handle secured to the VIG panel assembly near a side opposite the first edge of the VIG panel.

15. The refrigerated display case of claim 10, wherein the lighting element extends along a length of the hinge rail and is substantially parallel to the channel portion.

16. The refrigerated display case of claim 10, wherein the lighting element extends along at least a majority of a length of the hinge rail.

17. The refrigerated display case of claim 10, wherein the VIG panel assembly comprises a perimeter seal bonding the panes along a perimeter of the panes.

18. The refrigerated display case of claim 10, wherein the VIG comprises an anti-reflective coating configured to absorb or transmit light.
