Abstract
Abstract An implosion-proof cathode ray tube assembly, having a reinforcing band applied around the cathode tube, includes an adhesive tape wrapped around the cathode ray tube, a first tension band tightly wound surrounding the adhesive tape, a plurality of mounting lugs engaging the outer periphery of the first tension band at predetermined spaced positions, and a second tension band tightly surrounding the mounting lugs to force them against the first tension band.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
98 words
In an implosion-proof cathode ray tube assembly including a cathode ray tube, an adhesive tape wrapped around the periphery of a panel of said cathode ray tube and a first tension band tightly surrounding said adhesive tape, the improvement comprising a plurality of mounting lugs engaging the outer periphery of said first tension band at predetermined spaced positions, a second tension band tightly surrounding said mounting lugs to force them against said first tension band and anti-skid means provided between the peripheral surface of said first tension band and said mounting lugs to prevent movement of said lugs.
Claim 2
Dependent Claim
98 words
In an implosion-proof cathode ray tube assembly including a cathode ray tube, an adhesive tape wrapped around the periphery of a panel of said cathode ray tube and a first tension band tightly surrounding said adhesive tape, the improvement comprising a plurality of mounting lugs engaging the outer periphery of said first tension band at predetermined spaced positions, a second tension band tightly surrounding said mounting lugs to force them against said first tension band and anti-skid means provided between the peripheral surface of said first tension band and said mounting lugs to prevent movement of said lugs.
Claim 3
Dependent Claim
30 words
The implosion-proof cathode ray tube assembly according to claim 1, wherein said anti-skid means comprises a plurality of projections formed on said lugs in contact with said first tension band.
Claim 4
Dependent Claim
29 words
The implosion-proof cathode ray tube assembly according to claim 1, wherein said anti-skid means is formed on the inner surfaces of said mounting lugs facing said cathode ray tube.
Claim 5
Dependent Claim
31 words
