Abstract

There is disclosed a housing for a thin, flat display screen such as a liquid crystal display. The housing is formed of components comprising a front housing section having a front panel with an opening for exposing the screen of a flat screen device placed within the housing and a rear cover therefor which includes a hinged attachment to the front housing section which is recessed and inaccessible from the exterior of the closed housing. The assembly of front housing section and rear cover is secured with tangs carried on the lower rear edges of these components. The housing is adapted to be mounted in the chair arm of a passenger seat of commercial airliners, and includes a mounting bracket permitting it to be stowed within the chair arm when not in use. In this application it is essential that the housing have an outer covering of impact absorbing material to protect passengers from injury upon impact against the housing. It is also important that the housing be tamper and intrusion proof. To this end, the housing components are formed with interior metal liners which are surfaced with plastic foam coatings that completely encase the assembled housing. A control panel with membrane control buttons is integrally formed with the outer foam covering.

Claims

1. In a housing for a visual display device having a front face with a display screen, which housing includes a front housing section with a front wall, opposite side walls and top and bottom walls, with said front wall having a bezel surrounding said screen display, the improvement comprising:

a. an interior metal housing with opposite side walls and top and bottom walls receiving said visual display device and having a front panel with an opening in said front panel surrounding said display screen and a rear cover with a rear wall to enclose said visual display device, and an opening in the bottom wall of said housing;

b. a plastic foam thin layer having a thickness from 0.1 to 0.375 inch entirely covering said interior metal housing and rear cover;

c. an impervious plastic coating overlying said thin layer;

d. supporting mounting brackets received in said opening in said bottom wall of said housing.

2. The housing for a visual display device of claim 1 including a bezel surrounding said opening and formed integral with said plastic foam layer.

3. The housing for a visual display device of claim 2 wherein said bezel has a tapered cross section with a thin walled lip which is resilient to deflect and seal against said visual display device.

4. The housing for a visual display device of claim 3 wherein said lip of said bezel is peripherally disposed about said opening and resiliently deflects and seals about said display screen.

5. The housing for a visual display device of claim 1 wherein said visual display device includes a control panel having at least one control key on its forward face and including a second opening in said interior housing surrounding said display control panel, and including a flexible membrane of unfoamed plastic overlying said second opening.

6. The housing for a visual display device of claim 5 wherein said plastic membrane is one-piece with said plastic foam thin layer, of the same plastic as said thin layer.

7. The combination of the housing for a visual display device of claim 1 and a visual display device received within said housing.

8. The housing for a visual display device having a front face with a display screen and at least one control key, which housing includes:

a. a front housing section having a bezel surrounding said screen display and formed with

1. an interior metal housing receiving said visual display device and having a front panel with an opening surrounding said display screen;

2. a plastic foam thin layer having a thickness from 0.1 to 0.357 inch entirely covering said interior metal housing; and

3. an impervious coating overlaying said thin layer;

b. a control panel formed by a second opening in said interior metal housing surrounding said control panel, and a flexible membrane one-piece with said plastic foam thin layer and formed of the same plastic as said thin layer extending over second opening;

c. at least one button formed as one piece with said plastic membrane and of a thickness greater than said membrane to provide a button surface raised above the surface of said plastic membrane and located opposite said display device control key.

9. The housing for a visual display device of claim 8 including a post formed as one piece with and extending from the rear surface of said button into bearing contact with said display device control key of said visual display device.

10. The housing for a visual display device of claim 9 including a rigid sleeve received over said post.

11. The housing for a visual display device having a front face with a display screen, which housing includes:

a. a front housing section having a bezel surrounding said screen display and formed with

1. an interior metal housing receiving said visual display device and having a front panel with an opening surrounding said display screen, said formed with chamfered corners to provide a triangular aperture at each internal corner thereof;

2. a plastic foam thin layer foamed in place about said metal housing and having a thickness from 0.1 to 0.357 inch entirely covering said interior metal housing;

with said plastic foam extruded into said triangular apertures to form a plastic foam fillet in each of the interior corners of said housing; and

12. an impervious coating overlying said thin layer.

14. The housing for a visual display device of claim 12 wherein said attachment means on said front housing section comprises at least one front housing section bottom tang projecting along the bottom of said housing section from one of said side walls.

16. The secured housing for a visual display device having a screen display of claim 14 wherein each of said front housing section bottom tang and said rear housing cover bottom tang has an aperture, and said apertures are aligned when said rear housing cover is closed over said front housing section.

13. In a secured housing for a visual display device having a screen display, which housing includes a front panel having an opening surrounding said screen display, the improvement comprising:

d. a front housing section formed by said front panel and peripheral, orthogonal top and opposite side walls and having a rearwardly extending first tang dependent from said top wall and substantially coextensive therewith;

e. a rear housing cover comprising a rear panel having a top edge and a bottom edge and having a forwardly extending tang dependent from and substantially extensive with said top edge;

f. a retainer bracket positioned along said top wall of said front housing section and having a slot therein which receives said first and second tangs to form a detachable hinged attachment of said rear housing cover and said front housing section;

g. attachment means on the bottom wall of said front housing section and cooperating attachment means adjacent the bottom edge of said rear housing cover for securing said rear housing cover in a closed position against said front housing section.

15. The secured housing for a visual display device having a screen display of claim 13 wherein said cooperative attachment means includes at least one rear housing cover bottom tang projecting from the bottom edge of said rear housing cover and extending forwardly therefrom to a position adjacent said front housing bottom tang.

17. The secured housing for a visual display device having a screen display of claim 15 including a pair of front housing section bottom tangs and a pair of rear housing cover bottom tangs, one each located at opposite sides of said housing.
