Abstract

Abstract An integral supporting structure and magnetic shielding means for cathode-ray tubes includes a metal member and a wire member means in surrounding relationship to a cathode-ray tube. The metal member includes peripheral spaced bracket members each having a foot member extending forward thereof and a fastener member extending inwardly and rearwardly thereof. The wire member means engages the fastener member of each bracket member and is in pressure contacting relationship with the cathode ray tube.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 207 words
In a cathode ray tube system having a cathode ray tube with screen, funnel, and neck portions extending along a longitudinal axis, an integral supporting structure and magnetic shielding means for the cathode ray tube comprising: a metal member in substantially surrounding relationship to the screen portion of said cathode ray tube, said metal member including two substantially identical U-shaped metal portions each having a bottom section and an upstanding section affixed to opposite ends of the bottom section with the upstanding sections terminating in portions formed for engagement therebetween and cooperative engagement of the U-shpaed metal portions and a plurality of spaced integral bracket members each having a foot member extending forward of said metal member in the direction of said screen portion and in a plane substantially normal to said longitudinal axis and a fastener member extending inwardly and rearwardly of said metal member toward said neck portion of said cathode ray tube; and wire member means engaged by said fastener member of each of said bracket members and in surrounding and pressure-contacting relationship with said funnel portion of said cathode ray tube whereby said cathode ray tube is supported within a cabinet by said wire member means and magnetically shielded by said metal member.
Claim 2
Dependent Claim 207 words
In a cathode ray tube system having a cathode ray tube with screen, funnel, and neck portions extending along a longitudinal axis, an integral supporting structure and magnetic shielding means for the cathode ray tube comprising: a metal member in substantially surrounding relationship to the screen portion of said cathode ray tube, said metal member including two substantially identical U-shaped metal portions each having a bottom section and an upstanding section affixed to opposite ends of the bottom section with the upstanding sections terminating in portions formed for engagement therebetween and cooperative engagement of the U-shpaed metal portions and a plurality of spaced integral bracket members each having a foot member extending forward of said metal member in the direction of said screen portion and in a plane substantially normal to said longitudinal axis and a fastener member extending inwardly and rearwardly of said metal member toward said neck portion of said cathode ray tube; and wire member means engaged by said fastener member of each of said bracket members and in surrounding and pressure-contacting relationship with said funnel portion of said cathode ray tube whereby said cathode ray tube is supported within a cabinet by said wire member means and magnetically shielded by said metal member.
Claim 3
Dependent Claim 66 words
The integral supporting structure and magnetic shielding means of claim 1 wherein the terminating portions of said upstanding portions are in the form of tongue portions with one tongue portion of said upstanding portions of each of said U-shaped metal portion is formed to provide a slot for receiving a tongue portion of the other U-shaped metal portion whereby the U-shaped metal portions are cooperatively engaged.
Claim 4
Dependent Claim 22 words
The integral supporting structure and magnetic shielding means of claim 2 wherein said tongue portions are formed to receive a degaussing coil.
Claim 5
Dependent Claim 84 words
The integral supporting structure and magnetic shielding means of claim 1 wherein said metal member has a substantially planar surface extending substantially parallel to said longitudinal axis of said cathode ray tube, said fastener member of each of said bracket members includes at least one hook-shaped lug portion formed for engagement with said wire member means, and said wire member means includes adjustment means for varying the circumference thereof to effect said pressure contacting relationship with said funnel portion of said cathode ray tube.
Claim 6
Dependent Claim 58 words
The integral supporting structure and magnetic shielding means of claim 1 including a yoke ring member surrounding said funnel portion of said cathode ray tube in the vicinity of said neck portion and spring means affixed to and extending intermediate said yoke ring member and said fastener member of each of said bracket members of said metal member.
