Display case door assembly with vacuum panel and lighting features
First Claim
1. A display case door assembly for a temperature-controlled storage device, the display case door assembly comprising:
- a vacuum panel comprising a first vacuum pane, a second vacuum pane, and an evacuated gap between the first and second vacuum panes, wherein the evacuated gap provides thermal insulation for the vacuum panel;
an edge rail 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;
a lighting element 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 the closed position;
a mounting bracket coupled to at least one of the edge rail and the vacuum panel and defining a lighting channel within which the lighting element is contained;
a light cover coupled to the mounting bracket and forming a rear surface of the lighting channel, wherein the lighting element emits light through the light cover; and
a light cap coupled to the mounting bracket and configured to secure the light cover between the light cap and the mounting bracket.

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.
