Description

파괴되기 쉬운 지지코어 구조물을 갖는 확장식 탄성 중합 튜브의 커버 조립체
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 따른 확장식 탄성 중합튜브 및 내부 지지코어의 사시도,
제13도는 탄성 중합 류브와, 그의 지지코어 및 또다른 내층을 포함하는 선택적 실시예의 사시도.

Claims (10)

  1. 신장 및 해제후에 원래 치수 및 형상의 적어도 일부만큼은 복원될 수 있는 신장가능한 탄성 중합 튜브와, 상기 튜브를 반경 방향으로 신장된 상태로 지지하도록 충분한 강도 및 치수를 갖는 파괴되기 쉬운 내부 지지코어로서, 상기 튜브에 의해 생성되는 것보다 큰 힘을 받을 때 더욱 파괴되기 쉬우므로, 충분한 힘이 가해지면 파괴되어, 상기 튜브가 수축되도록 하는 상기 코어를 포함하는 커버 조립체.
  2. 제1항에 있어서, 상기 코어는 합성 수지로 제조되는 커버 조립체.
  3. 제2항에 있어서, 상기 수지는 에폭시인 커버 조립체.
  4. 제1항에 있어서, 상기 코어는 그의 길이방향을 따라 그의 파괴를 용이하게 하는 헬리컬 홈을 포함하는 커버 조립체.
  5. 제1항 있어서, 상기 코어는 그의 파괴를 용이하게 하는 화이버를 내부에 포함하는 커버 조립체.
  6. 제5항에 있어서, 상기 화이버는 모노 필라멘트인 커버 조립체.
  7. 제1항에 있어서, 상기 코어는 공간부를 포함하며, 따라서 불연속인 커버 조립제.
  8. 제7항에 있어서, 상기 코어는 성형된 화이버로 형성되며, 상기 공간부는 상기 화이버 사이에 형성되는 커버 조립체.
  9. 제1항에 있어서, 점성 밀봉재로 이루어지는 상기 코어내에 적어도 하나의 층을 더 포함하는 커버 조립체.
  10. 제9항에 있어서, 상기 점성 밀봉재는 매스틱 (mastic)인 커버 조립체.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
