Abstract

A multi-pane insulated glass door assembly in which the forward pane of the glass unit extends outwardly a greater 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.

10. The refrigerator door assembly of claim 1 in which said frame perimeter portion extends forwardly a small distance beyond the plane of the front face of said forward glass pane.

11. The refrigerator door assembly of claim 1 in which said metal frame has a rearwardly opening channel shape with outer and inner side walls disposed in parallel relation to each other.

12. The refrigerator door assembly of claim 11 in which said outer side wall is located in a plane in outwardly spaced relation to the outer periphery of said glass unit and forms one side of said forward frame perimeter portion, said forward frame perimeter portion having a generally U-shaped configuration with the other side thereof connected to the inner side wall by a transverse wall located rearwardly of the rear face of said forward glass pane.

13. The refrigerator door assembly of claim 11 including a sealing gasket supporting moulding engaging a rear side of said outer metal frame and enclosing said channel opening thereof.

14. The refrigerator door assembly of claim 13 in which said gasket supporting moulding extends inwardly over a rear peripheral side of said glass unit.

15. The refrigerator door assembly of claim 12 in which said metal frame inner side wall is formed with an outwardly extending flange in closely adjacent parallel reaction to a rear face of said forward glass pane which together with said other side of said forward frame perimeter portion defines an opening for receiving said moulding.

16. The refrigerator door assembly of claim 15 including adhesive means secured between said outwardly extending flange and a rear face of said forward glass pane.

17. The refrigerator door assembly of claim 12 in which said other side of said forward frame perimeter portion is formed with an inwardly extending flange disposed in rearwardly spaced relation to a rear face of said forward glass pane, and said moulding is formed with an L-shaped leg retained between said flange and said rear face of the forward glass pane.

18. The refrigerator door assembly comprising

a metal cabinet frame for mounting in an opening of a refrigerator cabinet,

an insulated glass door mounted for pivotal movement relative to said cabinet frame

said door including a glass unit having a plurality of glass panes disposed in side-by-side relation including a forward glass pane and a rear glass pane, a spacer interposed between adjacent panes for maintaining said panes in parallel relation with an air space therebetween, and means sealing said air space from the outside environment;

an outer metal frame about the periphery of said glass unit for supporting the weight of said glass unit; and

said metal frame including a unitary metallic frame member having a forward perimeter portion substantially in the plane of said forward glass pane disposed in outwardly spaced relation to the peripheral edge of said forward glass pane, said forward perimeter portion does not extend in front of said forward glass pane, thus defining a forwardly opening space about the outer peripheral edge of said forward glass pane and a rear portion extending inwardly behind said forward glass pane and rearwardly to a location in outwardly adjacent relation to the peripheral edge of said rear pane, and

a moulding disposed within said space between said forward frame perimeter portion and the peripheral edge of said forward glass pane.
