Abstract
A supporting device of a picture tube, which is, for example, of the type used in a television set mounted in an aircraft, wherein a shield or supporting member of the tube is connected to the tube at least at either one of the funnel and neck portions of the tube by resilient means so as to reduce the vibration of the tube and to minimize the size of the tube.
Claims7
A supporting device for supporting and positioning a picture tube within a shield member surrounding at least a funnel portion and a neck portion of said picture tube with a predetermined gap between said shield and said picture tube, said device comprising a first and at least one second resilient layer against each other in said gap between said shield member and said funnel and said neck portions of the picture tube and extending from the outer surface of said picture tube to the inner surface of said shield member in a radial direction relative to said picture tube, said second resilient layer having a greater resiliency than said first resilient layer.
In combination:
- a picture tube having a neck portion and a funnel portion within which a center of gravity of said picture tube falls;
- a shield member surrounding at least said funnel and neck portions of said picture tube with a gap formed between the outer surface of said funnel and neck portions of said picture tube and the inner surface to said shield member;
- a resilient member extending from the outer surface of said picture tube to the inner surface of said shield member for supporting and positioning said picture tube within said shield member, said resilient member being in the neighborhood of said center of gravity of the picture tube;
- and
- a mounting member fixed to said shield member at a position on the outer surface of said shield member which is substantially in registry with said center of gravity of the picture tube.
