Abstract
Abstract A plastic television chassis adapted for use in combination with a cathode-ray tube within an enclosure includes a base having integral snap-together parts disposed at opposite ends thereof. A pair of side frames are attached, respectively, to the opposite ends of the base in a substantially orthogonal orientation. Each side frame has integral snap-together parts disposed adjacent a first edge thereof for mating with the snap-together parts of the base, and also has integral slidable-groove parts disposed along a second edge thereof adjacent the first edge. A panel is attached to the side frames by integral slidable-groove parts disposed along opposite sides thereof for mating, respectively, with the slidable-groove parts of the side frames.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
164 words
A television chassis for use in combination with a cathod-ray tube within an enclosure comprising: a base having first integral connecting means disposed at opposite ends thereof, a pair of side frames attached, respectively, to said opposite ends of said base in a substantially orthogonal orientation, each side frame having second integral connecting means disposed adjacent a first edge thereof for mating with the first connecting means of said base, and also having third integral connecting means disposed along a second edge thereof adjacent said first edge; and a panel attached to said side frames, said panel having fourth integral connecting means disposed along opposite sides thereof for mating, respectively, with the third connecting means of said side frames, said first and said second integral connecting means comprising male-female snap-together means, said third and said fourth integral connecting means comprising slidable-groove means and slidable-tongue means, respectively, said panel being attached to said side frames by sliding along a direction substantially orthogonal to said base.
Claim 2
Dependent Claim
164 words
A television chassis for use in combination with a cathod-ray tube within an enclosure comprising: a base having first integral connecting means disposed at opposite ends thereof, a pair of side frames attached, respectively, to said opposite ends of said base in a substantially orthogonal orientation, each side frame having second integral connecting means disposed adjacent a first edge thereof for mating with the first connecting means of said base, and also having third integral connecting means disposed along a second edge thereof adjacent said first edge; and a panel attached to said side frames, said panel having fourth integral connecting means disposed along opposite sides thereof for mating, respectively, with the third connecting means of said side frames, said first and said second integral connecting means comprising male-female snap-together means, said third and said fourth integral connecting means comprising slidable-groove means and slidable-tongue means, respectively, said panel being attached to said side frames by sliding along a direction substantially orthogonal to said base.
Claim 3
Dependent Claim
63 words
A television chassis as defined in claim 1 wherein the snap-together means of said base comprise resilient arrow-shaped pins, and the snap-together means of said side frames comprise apertures for receiving said pins such that said pins bend during insertion of the heads thereof through said apertures and spring back to form an interlock therewith when the heads have passed through said apertures.
Claim 4
Dependent Claim
69 words
A television chassis as defined in claim 1 wherein the slidable-tongue means of sa.id panel comprise a pair of substantially T-shaped rails having a crossbar sections and extending along said slidable direction, and the slidable-groove means of said side frames comprise a pair of substantially C-shaped guides extending along said slidable direction such that the crossbar sections of said rails slide within and, thereby, interlock with said guides, respectively.
Claim 5
Dependent Claim
33 words
A television chassis as defined in claim 3 wherein each of said guides have integral latch means disposed at the ends thereof for locking said rails at a particular position along said guides.
Claim 6
Dependent Claim
54 words
A television chassis as defined in claim 4 wherein each of said latch means comprises a resilient arrow-shaped pinhalf having a back and positioned such that the crossbar section of the adjacent rail bends said pinhalf while sliding within the guide and then allows said pinhalf to spring back to form a interlock therewith.
Claim 7
Dependent Claim
39 words
A television chassis as defined in claim 5 wherein the crossbar section of each rail has an interlocking groove disposed therealong to receive the head of said pinhalf and, thereby, lock the rail at a midway position for servicing.
Claim 8
Dependent Claim
54 words
A television chassis as defined in claim 5 wherein each of said latch means has a section of the supporting side frame positioned adjacent thereto so as to contact the back of said pinhalf when severely bent and stop any further bending, thereby providing an anti-overstress feature to prevent accidental breakage of said pinhalves.
Claim 9
Dependent Claim
32 words
A television chassis as defined in claim 1 wherein said side frames have integral guide means for allowing a printed circuit board to be slid into a predetermined location and supported thereat.
Claim 10
Dependent Claim
25 words
A television chassis as defined in claim 8 wherein said panel has integral snap means for holding a printed circuit board at a predetermined location.
Claim 11
Dependent Claim
52 words
A television chassis as defined in claim 9 wherein said integral snap means comprises a resilient arrow-shaped pin positioned such that said pin bends while the printed circuit board is being slid into location and springs back to form a holding interlock therewith when said printed circuit board reaches the predetermined location.
Claim 12
Dependent Claim
20 words
A television chassis as defined in claim 1 wherein said base, said side frames, and said panel comprise injection-molded plastic.
Claim 13
Dependent Claim
36 words
A television chassis as defined in claim 11 wherein each of said side frames has a molded-in cavity disposed along a third edge thereof opposite said second edge, said cavity for securing a degaussing coil therein.
Claim 14
Dependent Claim
34 words
A television chassis as defined in claim 12 wherein each of said side frames has a pair of apertures disposed therein along a third side for attaching said cathode-ray tube thereto via mounting lugs.
Claim 15
Dependent Claim
23 words
A television chassis as defined in claim 11 wherein said panel has at least one molded-in hook for securing a wire harness thereto.
Claim 16
Dependent Claim
25 words
A television chassis as defined in claim 1 wherein said panel has locating holes positioned therein for aligning said chassis with respect to said enclosure.
Claim 17
Dependent Claim
28 words
A television chassis as defined in claim 1 wherein said panel has openings positioned therein so as to allow clearance for automatic final electrical adjustments during final assembly.
