Abstract
Abstract A unitary CRT display assembly comprises a chassis pan for supporting a printed circuit chassis and components from a CRT by means of an adjustable tension strap surrounding the periphery of the CRT faceplate or by a pair of mounting lugs coupled to the mounting ears of the CRT. The construction enables the chassis pan, CRT and components to be shipped, handled and readily assembled as a unit into a manufacturer's cabinet.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
125 words
A unitary CRT display assembly adapted for ready installation in a cabinet comprising: a CRT having a faceplate structure including mounting ears in an anti-implosion means affixing the mounting ears to the faceplate; a chassis and a chassis mounting pan separate from said CRT, said chassis mounting pan being supported from said CRT faceplate structure for enabling small movements thereof in said cabinet; cabinet support means for firmly supporting said chassis mounting pan in position in said cabinet; means including a strap having slots, with said mounting ears protruding through said slots when said strap is in engagement with said faceplate structure for supporting said chassis mounting pan from said CRT faceplate structure for installation into said cabinet; and tension adjustment means on said strap.
Claim 2
Dependent Claim
125 words
A unitary CRT display assembly adapted for ready installation in a cabinet comprising: a CRT having a faceplate structure including mounting ears in an anti-implosion means affixing the mounting ears to the faceplate; a chassis and a chassis mounting pan separate from said CRT, said chassis mounting pan being supported from said CRT faceplate structure for enabling small movements thereof in said cabinet; cabinet support means for firmly supporting said chassis mounting pan in position in said cabinet; means including a strap having slots, with said mounting ears protruding through said slots when said strap is in engagement with said faceplate structure for supporting said chassis mounting pan from said CRT faceplate structure for installation into said cabinet; and tension adjustment means on said strap.
Claim 3
Dependent Claim
17 words
The display assembly of claim 1 wherein said strap engages said faceplate structure behind said mounting ears.
Claim 4
Dependent Claim
116 words
A unitary CRT display assembly adapted for ready installation in a cabinet comprising: a CRT having a faceplate structure including mounting ears and an anti-implosion means affixing said mounting ears to said faceplate; a chassis and a chassis mounting pan separate from said CRT, said chassis mounting pan being supported from said CRT faceplate structure for enabling small positioning movements thereof in said cabinet; cabinet support means for firmly supporting said chassis mounting pan in position in said cabinet; and means supporting said chassis mounting pan from said CRT faceplate structure for installation in said cabinet, wherein said chassis mounting pan includes protruding lugs for supporting cooperation with some of said mounting ears of said CRT.
Claim 5
Dependent Claim
116 words
A unitary CRT display assembly adapted for ready installation in a cabinet comprising: a CRT having a faceplate structure including mounting ears and an anti-implosion means affixing said mounting ears to said faceplate; a chassis and a chassis mounting pan separate from said CRT, said chassis mounting pan being supported from said CRT faceplate structure for enabling small positioning movements thereof in said cabinet; cabinet support means for firmly supporting said chassis mounting pan in position in said cabinet; and means supporting said chassis mounting pan from said CRT faceplate structure for installation in said cabinet, wherein said chassis mounting pan includes protruding lugs for supporting cooperation with some of said mounting ears of said CRT.
Claim 6
Dependent Claim
28 words
The display assembly of claim 3 wherein said lugs each includes an enlarged aperture to enable small movements of said chassis mounting pan during assembly in said cabinet.
Claim 7
Dependent Claim
84 words
A unitary CRT display assembly comprising: a CRT having a faceplate and mounting ears attached thereto by an anti-implosion band; a chassis and a chassis mounting pan separate from said CRT and a mounting strap attached thereto for engaging said CRT near the periphery of said faceplate; means supporting said chassis mounting pan to said CRT by said strap; and means for enabling the position of said chassis mounting pan to be adjusted slightly with respect to said CRT for installation in a cabinet.
Claim 8
Dependent Claim
84 words
A unitary CRT display assembly comprising: a CRT having a faceplate and mounting ears attached thereto by an anti-implosion band; a chassis and a chassis mounting pan separate from said CRT and a mounting strap attached thereto for engaging said CRT near the periphery of said faceplate; means supporting said chassis mounting pan to said CRT by said strap; and means for enabling the position of said chassis mounting pan to be adjusted slightly with respect to said CRT for installation in a cabinet.
Claim 9
Dependent Claim
29 words
