Refrigerator door assembly
View Patent ↗A refrigerator door assembly for mounting within an opening of a refrigerator cabinet for movement relative to the refrigerator consisting in combination the following components within a hollow rigid plastic welded structural door frame: a multi-paned insulated glass pack drop-in unit, a bushing means and a hinge means, each secured in the door frame and cooperating to support the dynamic and torsional loads of the glass pack unit.
1. A refrigerator door assembly for mounting in an opening of a refrigerator cabinet comprising in combination:
four hollow rigid extruded plastic frame members, each of said frame members terminating in a miter cut, each pair of adjacent frame members being secured by a weld forming a unitary structural support frame having spaced ribs on an internal surface, said structural frame having generally an L-shaped cross-sectional configuration defining an enclosed chamber forming a ledge for supporting at least one multi-glazed insulated glass unit having a separator between panes, and a recess adapted to receive a securing means for removably securing said insulated glass pack unit extending along the inner perimeter of said structural frame; pivoting means mounted in said frame for movement of the refrigerator door for rotation to said cabinet comprising a cartridge hinge and bushing assembly at the top and bottom of said door extending past the glass unit; said structural frame having lateral edges defining top, side, and bottom wherein the top and bottom edges have sockets for accommodating pivot means, said sockets being in spatial communication with the enclosed chamber, whereby said glass unit is drop-in mounted within the frame.
2. The refrigerator door assembly of claim 1 wherein said hinge means automatically closes the door when it is opened and released.
3. The refrigerator door assembly of claim 1 including a sealant along the edges.
4. The refrigerator door assembly of claim 1 wherein the enclosed chamber includes spaced ribs provided on the internal surface.
5. The refrigerator door assembly of claim 4 wherein said spaced ribs provide an interference fit for the hinge means in cartridge form.
6. The refrigerator door assembly of claim 1 wherein said hinge means are inserted into sockets and internal chamber of said frame and extended beyond the edges of the insulated glass pack unit.
7. The refrigerator door assembly of claim 1 including vibration dampeners comprising plastic blocks.
8. The refrigerator door assembly of claim 1 wherein said enclosed chamber defines an interference fit between the frame and the hinge and bushing assemblies.
9. The refrigerator door assembly of claim 1 including a resilient seal around the periphery.
