Claims (5)

  1. 조향가능 안내선에 있어서, 접근 단부 및 격설 단부를 갖는 연신 고체벽으로 된 관형 주요선,접근 단부 및 격설 단부를 가지며 자체의 접근 단부가 주요선의 격설 단부에 연결되어 있고 주요선으로부터 격설되어 연장되는 연신 나선 코일, 접근 단부 및 격설 단부를 가지며 주요선의 격설 단부로부터 격설되어 연장되고 상기 단부에 연결되어 있는 격설 철심선, 주요선의 격설 단부에 인접되고 격설 철심선의 접근 단부에 인접된 당김선 개구부를 형성하는 장치, 접근 단부 및 격설 단부를 갖는 당김선, 당김선의 격설 단부를 나선 코일의 격설 단부와 함께 연결시키는 종방향으로 항복될 수 있는 내측 스프링으로 구성되되, 상기 철심선은 코일의 루우멘을 통해 연장되고 만곡된 단부 캡에서 코일의 격설 선단에 연결된 격설 선단을 가지며, 상기 당김선의 격설 단부는 나선 코일의 격설 선단보다 짧게 종결되고, 상기 당김선은 상기 개구부를 통해 수요선의 루우멘 내로 철심선과 코일 사이로 연장되며, 상기 당김선은 주요선의 루우멘을 통해 주요선의 접근 단부로 연장되어, 당김선의 접근 단부가 당김선에 장력을 인가하도록 당겨질 수 있게 되며, 이에 따라 상기 내측 스프링을 인장시키고 외측 나선 코일의 격설 요소의 적어도 일부분을 만곡된 형태로 발출하는 것을 특징으로 하는 조향가능 안내선.
  2. 제1항에 있어서, 상기 주요선의 외경이 약 0.508㎜(0.020in) 이하인 것을 특징으로 하는 조향가능 안내선.
  3. 제1항 또는 2항에 있어서, 상기 철심선이 격설방향으로 경사져 있고 격설 철심선의 격설 선단은 평평한 것을 특징으로 하는 조향가능 안내선.
  4. 제3항에 있어서, 상기 내측스프링이 외측스프링내에 편심되어 배설되어 있고 철심선의 평평한 격설 선단의 평면을 따라 연장되는 것을 특징으로 하는 안내선.
  5. 제4항에 있어서, 상기 당김선의 격설 구역이 당김선 개구부의 근접 위치로부터 상기 개구부의 연결부까지 연장되되, 내측 스프링은 직경이 감소되어 있는 것을 특징으로 하는 안내선.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
