Abstract
Abstract A structure for supporting a particular type of plasma display panel. The panel is of the type formed of two flat rectangular plates attached to each other face to face with crossed longitudinal axes, the active panel area comprising the face to face surfaces. Support bars with resilient gaskets interposed between themselves and the two plates provide a shock-resistant mounting. Electronic circuitry can be attached to the support bars to provide a compact package with electronic circuitry adjacent to and substantially coplanar with the panel itself.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
203 words
Apparatus for supporting a plasma display panel of the type formed of first and second flat approximately rectangular plates each longer than the other is wide and firmly attached to each other face to face with each end of each extending past a lateral edge of the other, and comprising: (a) first through fourth resilient gasket strips each having a thickened edge portion and a less thick retaining tab portion, each of said gaskets' retaining tab portions lying transverse to and touching the face of a panel plate end extending past a lateral edge of the other panel plate, with said gasket's thickened edge extending along and touching a lateral edge of said other panel plate; (b) first and second mounting frames, each having a pair of interior edges lying adjacent to and extending along a gasket, each edge extending at least to the lateral edges of the panel plate adjacent the adjacent gasket's retaining tab and each said edge so spaced from the other edge in its frame as to cause each edge to compress its adjacent gasket's thickened edge portion; and (c) means for supporting each frame so as to trap the gaskets' retaining tabs between the frames and panel plates.
Claim 2
Dependent Claim
203 words
Apparatus for supporting a plasma display panel of the type formed of first and second flat approximately rectangular plates each longer than the other is wide and firmly attached to each other face to face with each end of each extending past a lateral edge of the other, and comprising: (a) first through fourth resilient gasket strips each having a thickened edge portion and a less thick retaining tab portion, each of said gaskets' retaining tab portions lying transverse to and touching the face of a panel plate end extending past a lateral edge of the other panel plate, with said gasket's thickened edge extending along and touching a lateral edge of said other panel plate; (b) first and second mounting frames, each having a pair of interior edges lying adjacent to and extending along a gasket, each edge extending at least to the lateral edges of the panel plate adjacent the adjacent gasket's retaining tab and each said edge so spaced from the other edge in its frame as to cause each edge to compress its adjacent gasket's thickened edge portion; and (c) means for supporting each frame so as to trap the gaskets' retaining tabs between the frames and panel plates.
Claim 3
Dependent Claim
41 words
The apparatus of claim 1, wherein the first frame comprises first and second bars defining the sides of an opening therein wide enough to straddle the first panel plate and the gaskets' thickened edge portions adjacent thereto, with an interference fit.
Claim 4
Dependent Claim
74 words
The apparatus of claim 1, wherein the first mounting frame comprises a first flat plate having an opening of greater length than the first panel plate's length and whose width is slightly less than the distance between outwardly facing edges of the thickened edge portion of the gaskets in position adjacent the first panel plate's sides, the edges of the opening defining its width forming an interference fit with the gasket's thickened edge portions.
Claim 5
Dependent Claim
61 words
The apparatus of claim 3 further comprising: (a) a fifth resilient flat gasket strip; (b) a mounting element having a flat surface; and (c) means for attaching the mounting element to the first flat plate with the fifth gasket gripped between the mounting element's flat surface and the surface of the first flat plate facing away from the second mounting frame.
Claim 6
Dependent Claim
17 words
The apparatus of claim 4, wherein the first through fourth gaskets have a "P" shaped cross section.
Claim 7
Dependent Claim
33 words
The apparatus of claim 4, wherein the means for attaching the first mounting element comprise bolts passing through the facing bar and pressing the bar, gaskets, mounting element, and panel plate end together.
Claim 8
Dependent Claim
35 words
The apparatus of claim 5, wherein a portion of the mounting element includes an area with a predetermined optical characteristic covering at least a portion of the face to face areas of the panel plates.
Claim 9
Dependent Claim
14 words
The apparatus of claim 7, wherein the predetermined optical characteristic is altered light transmissibility.
Claim 10
Dependent Claim
12 words
The apparatus of claim 7, wherein the predetermined optical characteristic is transparency.
Claim 11
Dependent Claim
14 words
The apparatus of claim 1, wherein each gasket has a "P" shaped cross section.
Claim 12
Dependent Claim
14 words
The apparatus of claim 10, wherein the curved portion of the "P" is hollow.
Claim 13
Dependent Claim
153 words
The apparatus of claim 1, further comprising: (a) first and second mounting elements comprising flat plates, at least one of which has a central window therein, and both having greater length and width than either of the panel plates' length; (b) fifth through eighth gaskets; (c) means for attaching the first and second mounting elements to the first and second mounting frames, each of the mounting elements in facing relationship to one face of the plasma display panel, and each mounting element gripping two of the fifth through eighth gaskets between itself and the nearer of the two panel plates with the window framing the face to face portion of the plasma display panel; (d) a circuit board interposed between the first and second mounting elements adjacent the periphery of the plasma display panel; and (e) means for attaching the circuit board to at least one of the first and second mounting elements.
