A foldable assembly comprising:
- first and second substantially planar and rectangular panels each having respective first and second short sides and respective first and second long sides;
- means for foldably joining said first and second panels so that said panels may be selectively placed in a folded configuration or in an unfolded configuration in which their planes are substantially coplanar;
- said means for foldably joining said first and second panels joining said panels so that said second long side of said first panel is joined to said first long side of said second panel, said first short sides are in substantial alignment and said second short sides are in substantial alignment;
- a first subassembly attached to said first panel proximate said first long side hereof;
- a second subassembly attached to said second panel proximate said second long side hereof;
- said first subassembly having first and second channel portions each with a generally C-shaped cross-section proximate said first and second short sides, respectively, of said first panel;
- said second subassembly having first and second channel portions each with a generally C-shaped cross-section proximate said first and second short sides, respectively, of said second panel;
- first and second bar members each having first and second ends;
- means for pivotably attaching said first end of said first bar member within said first C-shaped channel portion of said first subassembly so that said first bar member may be rotated in a plane substantially parallel to said plane of said first panel from a storage position when said panels are in said folded configuration to a support position in which said second end of said first bar member is received within said first C-shaped channel portion of said second assembly so that said first bar member spans between said first and second subassemblies when said panels are in said unfolded configuration;
- and means for pivotably attaching said first end of said second bar member within said second C-shaped channel portion of one of said first and second subassemblies so that said second bar member may be rotated in a plane substantially parallel to said plane of the respective one of said first and second panels from a storage position when said panels are in said folded configuration to a support position in which said second end of said second bar member is received within said second C-shaped channel portion of the other one of said first and second subassemblies so that said second bar member spans between said first and second subassemblies when said panels are in said unfolded configuration.
