Stacking modular display

1 . A display device, comprising:

a plurality of stackable modular units, each said modular unit comprising:

a base panel having a flat central portion and curved opposed portions;

a boxy structure attached to said base panel, said boxy structure having top and bottom panels, and first and second side panels connected to said top and bottom panels providing a boxy structure with an open front, said top and side panels forming a flat central surface and curved side portions adapted to receive a base panel thereon to thereby stack one modular unit atop another modular unit; and

a retaining member, disposed adjacent said open front inside said boxy structure, fastened to said side panels and extending laterally between side panels and said top and bottom panels.

2 . A display device, as set forth in claim 1 , including a plurality of reinforcing ribs attached to said side panels.

3 . A display device, as set forth in claim 1 , including a plurality of reinforcing ribs attached to said top panel.

4 . (canceled)

5 . A display device, as set forth in claim 1 , wherein said retaining member is positioned closer to said bottom panel than to said top panel inside said boxy structure.

6 . A display device, as set forth in claim 1 , wherein said retaining member is parallel to said bottom panel.

7 . A display device, comprising:

a plurality of stackable modular units, each said modular unit comprising:

a base panel having a flat central portion and curved opposed end portions;

a boxy structure attached to said base panel, said boxy structure having top and bottom panels, and first and second side panels connected to said top and bottom panels providing a boxy structure with an open front and an open rear, said top and side panels forming a flat central surface and curved side portions adapted to receive a base panel thereon to thereby stack one modular unit atop another modular unit;

a first retaining member, disposed adjacent said open front inside said boxy structure, fastened to said side panels and extending laterally between said side panels and said top and bottom panels; and

a second retaining member, disposed adjacent said open rear inside said boxy structure, fastened to said side panels and extending laterally between said top and bottom panels.

8 . A display device, as set forth in claim 7 , wherein said retaining members are parallel to said bottom panel.

9 . A display device, comprising:

a first modular unit comprising a base panel having a flat central portion and curved opposed end portions; a boxy structure attached to said base panel, said boxy structure having top and bottom panels, and side panels connected to said top and bottom panels and defining front and rear openings adjacent said curved opposed end portions of said base panel, said top and side panels forming a flat central surface and curved side portions; and a retaining member disposed adjacent said open front inside said boxy structure fastened to said side panels and extending laterally between said side panels and said top and bottom panels; and

a second modular unit comprising a base panel having a flat central portion and curved opposed end portions; a boxy structure attached to said base panel, said boxy structure having top and bottom panels, and side panels connected to said top and bottom panels and defining front and rear openings adjacent said central portion of said base panel, said top and side panels forming a flat central surface and curved side portions adapted to receive said base panel of said first modular unit thereon to thereby stack said second modular unit atop said first modular unit so that said front and rear openings of said first modular unit are angularly disposed ninety degrees from said front and rear openings of said second modular unit; and a retaining member disposed adjacent said open front inside said boxy structure fastened to said side panels and extending laterally between said side panels and said top and bottom panels.
