Abstract

A multi-pane insulated glass door assembly in which the forward pane of the glass unit extends outwardly a greater distance than the panes rearwardly thereof and is supported by an outer metal frame having a relatively narrow forwardly extending perimeter portion adjacent the peripheral edge of the forward glass pane so as to provide the door with a modernistic, substantially all glass front appearance. In the illustrated embodiment, the outer metal frame has a rear portion extending inwardly behind the forward glass pane and a moulding is interposed between the forwardly extending perimeter portion of the metal frame and the peripheral edge of the forward glass pane to provide a finished appearance. A dark ink is affixed to an inside peripheral face of the forward glass pane for masking the peripheral components of the door assembly from sight through the forward glass pane from the front side thereof.

Claims

1. A refrigerator door assembly comprising a cabinet frame for mounting in an opening of a refrigerator cabinet, an insulated glass door mounted for movement relative to said cabinet frame, said glass door comprising an insulated glass unit having a plurality of glass panes disposed in side-by-side relation and including a forward pane and a pane disposed rearwardly of said forward pane, a spacer interposed between at least some of said panes for maintaining said panes in parallel relation with an air space therebetween, an outer door support frame about the periphery of said glass unit for supporting the weight of said glass unit, said forward glass pane being larger in size than said rearwardly disposed pane and extending outwardly substantially to the outer perimeter of said door, said support frame having at least a portion being disposed rearwardly of said forward glass pane and being without any portion extending in overlapping relation to a front side of said forward glass pane, and masking means on said forward glass pane about the periphery thereof for preventing viewing of said spacer through said forward glass pane from a front side thereof while permitting unobstructed viewing of the interior of the refrigerator cabinet within which said door is mounted.

2. The refrigerator door assembly of claim 1 including sealant means associated with said glass panes and spacer for sealing said air space, and said masking means prevents viewing of said sealant means through said forward glass pane from a front side thereof.

3. The refrigerator door assembly of claim 1 including adhesive means between the said door support frame and an outer peripheral portion of said glass unit for securing said glass unit within said door support frame, and said masking means prevents viewing of said adhesive means through said forward glass pane from a front side thereof.

4. The refrigerator door assembly of claim 3 in which said adhesive is polysulfide.

5. The refrigerator door assembly of claim 1 including an intermediate pane disposed between said forward and rearwardly disposed panes, and said outer door support frame is disposed outwardly of the peripheral edges of said intermediate and rearwardly disposed panes.

6. The refrigerator door assembly of claim 1 in which said masking means is a silk screen coating affixed to an outer peripheral portion of said forward glass pane.

7. The refrigerator door assembly of claim 6 in which said silk screen is affixed to a rear face of said forward glass pane.

8. The refrigerator door assembly of claim 1 including a relatively narrow perimeter frame portion extending forwardly disposed in adjacent relation to an outer peripheral edge of said forward glass pane.

9. The refrigerator door assembly of claim 8 in which said narrow perimeter frame portion is an integral part of said door support frame.

10. The refrigerator door assembly of claim 8 including a molding interposed between said narrow perimeter frame portion and the outer peripheral edge of said forward pane.

11. The refrigerator door assembly of claim 10 in which said molding has a forward end extending over a front side of said narrow perimeter frame portion of said door frame and a front side of said forward glass pane.

12. The refrigerator door assembly of claim 8 in which said door support frame has a portion extending rearwardly to a location adjacent an outer peripheral edge of said rearwardly disposed pane.

13. The refrigerator door assembly of claim 1 in which said cabinet frame and door support frame are made of metal.
