Abstract

A large format video display includes modular construction to permit the repair and exchange of single modules. Each module includes a pair of enantiomorphic side panels, each including top and bottom flanges and a rear flange extending inwardly. At the front end of each rectangular side panel, a plurality of formed bends define an integral rectangular column extending outwardly from the panel. A generally rectangular bottom tray includes a rear floor portion for supporting a video projector unit aimed toward the front of the module. A pair of ears extend outwardly from the front ends of the side panels, and are configured each to be engaged with the integral column of the respective adjacent side panel. The bottom tray is dimensioned to engage the bottom flanges of the side panels, so that the side panels support the weight of the bottom tray and the video processor. A rear panel is secured to the rear flanges of the side panels and the bottom tray, and a top panel is joined to the upper flanges of the side panels and to the upper portions of the integral columns of the side panels. A medial panel extends between the side panels, the bottom tray, and the top panel, and is disposed midway between the front and rear of the module. The video projector unit beams the image through a central cutout in the medial panel to an image forming screen joined to the front of the assembly. The integral column formations extending of any two modular units in abutting, side-by-side relationship define a spacing or gap between confronting sides thereof. A plurality of structural beams extending vertically to impinge on the integral column portions of two adjacent modules. Adjacent modules are fastened to the beam disposed therebetween, forming adjacent columns of modules.

Claims

1. A large format video display, including:

a plurality of video modules, each of said modules including an image forming screen, video projector means for illuminating said screen with a video image in rear projection fashion, housing means for enclosing said video projector means and securing said screen, said housing means also comprising structural means for supporting said video projector means and said screen;

said housing means including a bottom tray having means for engaging said video projector means in supporting relationship; and

,

said means for engaging including a raised floor portion of said bottom tray.

2. A large format video display, including:

a plurality of video modules, each of said modules including an image forming screen, video projector means for illuminating said screen with a video image in rear projection fashion, housing means for enclosing said video projector means and securing said screen, said housing means also comprising structural means for supporting said video projector means and said screen;

said housing means including a bottom tray having means for engaging said video projector means in supporting relationship;

said bottom tray including opposed side edges, and a pair of ear portions extending laterally outwardly from a front portion of said side edges, said ear portions being spaced apart a distance generally the same as the width of said screen.

3. The large format video display of claim 2, further including a pair of side panels extending generally parallel and upwardly from said side edges of said bottom tray.

4. The large format video display of claim 3, further including a column portion formed at a front portion of each of said side panels, said column portion engaging and securing a respective one of said ear portions of said bottom tray.

5. The large format video display of claim 4, wherein said column portions of said side panels are spaced apart a distance generally the same as said width of said screen.

6. The large format video display of claim 5, further including a first plurality of support beams extending between and joining vertically stacked modules to form columns of said modules, said columns joined side-by-side to define a matrix of said modules, the screen of each module disposed in side-by-side and top-to-bottom edge abutment with adjacent screens in said matrix.

7. The large format video display of claim 6, wherein each of said first plurality of support beams extends in abutment to confronting column portions of a pair of adjacent modules in said matrix.

8. The large format video display of claim 7, wherein each of said first plurality of support beams extends in abutment to confronting side portions of a pair of adjacent modules in said matrix, and means for securing said confronting side portions to said first plurality of support beams.

9. The large format video display of claim 8, further including a second plurality of support beams extending between and joining vertically stacked modules to form columns of said modules, said second plurality of support beams each extending in abutment to confronting rear side portions of a pair of adjacent modules in said matrix, an means for securing said support beams to said confronting rear side portions.

10. The large format video display of claim 3, wherein each of said side panels includes a flange extending along a bottom edge thereof, said flange disposed to extend below a portion of said bottom tray in supporting relationship.

11. The large format video display of claim 10, further including a top panel secured to the upper edges of said side panels.

12. The large format video display of claim 11, further including a rear panel secured to the rear edges of said side panels.

13. The large format video display of claim 12, further including a medial panel disposed medially between said rear panel and said screen and extending to be secured to said side panels, said bottom tray, and said top panel.

14. The large format video display of claim 13, wherein said medial panel is disposed between said video projector means and said screen, and further including a central cutout positioned to pass the image beam from said video projector means to said screen.
