Food service cart door structure

In a food service cart having a cabinet with first and second oppositely facing sidewalls and a opening in each said sidewall, a tray storage area within the cabinet, and a flat endwall joining between the first and second sidewalls, improved structure for selectively sealing said opening and allowing unobstructed access to said tray storage area through said openings for inserting or removing trays comprising:

• a first door having substantially flat, inside and outside wall surfaces, said inside wall surface extending at least partially across said opening of the first sidewall with the first door in a closed position;
• first hinge means pivotally mounting the first door to the cabinet to pivot about a first pivot to an open position in which said outside wall surface of the first door is in parallel juxtaposition with the endwall;
• a second door substantially similar to said first door and having substantially flat, inside and outside wall surfaces, each of said first and second doors having distal edges, said inside surface of the second door extending at least partially across said opening of the second sidewall with the second door in a closed position;
• and
• second hinge means pivotally mounting the second door to the cabinet to pivot about a second pivot, said second hinge having a length greater than said first hinge by substantially the thickness of said first door, the second door being disposed in an open position in overlapping relationship with the first door with the outside surface of the second door being in substantially parallel juxtaposition with the inside surface of the first door in the open position, said first pivot being spaced from the plane of said endwall approximately one-half the thickness of said first door and said second pivot being spaced from the plane of said endwall approximately the thickness of said first door plus approximately one-half the thickness of said second door, thereby disposing said distal edges of the doors in alignment at said opposite sidewalls when the doors are in the cloed position.
