Description

압축 둔부 나사
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 목에 틈새가 있는 대퇴부에 적용한 압축 둔부 나사의 횡단면을 묘사한 것임.
제2도는 제1도의 2-2선을 따라 취한 횡단면도임.
제3도는 느림 나사의 측면도임.

Claims (13)

  1. 대퇴부의 대퇴부 머리를 고정하기 위한 압축 둔부나사로서, 그 압축 둔부나사는 대퇴부에 부착되도록 적용한 판으로 구성되며, 그 판은 통로로 뻗어 있는 원통을 포함하며, 통로는 대퇴부와 대퇴부 머리에 형성되고, 원통은 그속을 통하여 뻗어 있는 구멍에 맞게되고, 첫번째 부재는 대퇴부 머리에 결합되어, 원통 구멍으로 뻗쳐 있으며, 두번째 부재는 첫번째 부재와 결합되어서 통로로 부터 원통의 퇴거를 막도록하며, 열쇠장치는 첫번 부재 및 원통과 결합되어 원통과 첫번 부재간의 회전을 제한하게하는 것으로 원통이 대퇴부에 부착된 판의 일부에 인접한 하부측과 판 부분으로 부터 떨어져 있는 상부측을 제한하는 것에 특징이 있으며, 자물쇠 장치는 하부측의 원통내에 맞게되어 있는 홈과 홈내에 배치된 핀으로 구성되며 그 핀은 원통 구멍속으로 뻗어있고, 첫번 부재는 핀을 수용할 오목면으로 제한되어 있어서 핀이 첫번 부재 및 원통과 알맞은 간섭을 받게되는 상기 압축둔부 나사.
  2. 핀과 홈이 대체로 원통의 길이에 걸쳐 하중을 전달하도록 원통의 길이로 뻗어 있으며 이때 첫번 부재와 원통사이의 회전이 처음 시작되는 청구범위 제1항의 압축둔부 나사.
  3. 두번째 부재가 홈으로 부터 핀의 퇴거를 방해하여 이 때 두번째 부재가 첫번부재와 결합되는 청구범위 제1항의 압축둔부 나사.
  4. 첫번째 부재는 첫째 단부에서 홈이 파지고 오목면은 거기에서 뻗치도록 홈과 일치시킨 청구범위 제1항의 압축둔부 나사.
  5. 원통이 제2부재와 인접하여 어깨에 맞게되어 있고 홈이 어깨에서부터 원통의 기부에 가까운 쪽 단부까지 뻗어 있는 청구범위 제1항의 압축둔부 나사.
  6. 핀이 어깨와 관련되어 공간을 형성한 제1부재와 원통간의 간섭으로 치밀하게 한정되어 있는 청구범위 제5항의 압축 둔부나사.
  7. 원통이 홈속의 핀을 휘기 쉽게 지탱하도록 장치를 제한하고 핀은 대체로 제1부재 홈과 핀사이에서 일치 되게 하기 위해서 원통의 유도단부로 뻗어 있으며 이때 원통은 처음으로 제1부재상에 맞춰지는 청구범위 제1항의 압축 둔부 나사.
  8. 홈이 원통용의 대체로 동일형의 원통형 표면에서 유일한 간섭을 받고 원통은 홈으로 부터 떨어져서 일정한 방사형 두께를 구멍에서 부터 원통의 외부 표면에까지 제한하는 청구범위 제1항의 압축 둔부 나사.
  9. 제1부재 오목면이 나사선에 인접하지 않은 제1부재의 중간위치로 홈이 파진 제1단부로 부터 뻗어 있어서 최소한의 물질이 오목면을 형성하기 위해 제1부재로 부터 이동시켜 핀이 장치되게 하는 청구범위 제1항의 압축둔부 나사.
  10. 대퇴부 뼈대에 대퇴부 머리를 고정하기 위한 압축둔부 나사로서, 압축둔부 나사는 대퇴부에 부착되게 적용한 판으로 구성되며, 그 판은 통로 속으로 뻗친 원통으로 상부를 향해 유도되며, 통로는 대퇴부와 대퇴부 머리에 설치되며, 한쌍의 부재는 대퇴부 머리 및 원통과 결합되어 대퇴부에 연결된 대퇴부 머리를 지탱하면서 통로로 부터 원통의 퇴거를 막으며, 원통 상부측은 둔부에 대한 정상적인 이동 형태일 때에 팽창력이 발생하며, 원통 하부측은 둔부와 한쌍의 부재중 하나 및 원통과 결합된 자물쇠 장치에 대한 정상적인 이동형태일 때 압축이 생겨 한개의 부재와 원통 사이의 회전을 막고, 자물쇠 장치는 방사형 두께를 통한 구멍이 없이 원통의 상측에 일정한 방사형 두께의 동일형의 원통형 측면을 제공하기 위해서 그 하부측에 단독으로 원통과 결합되어 있어서, 원통의 상부측에 주어진 팽창력이 일정한 방사형 두께의 동일형태의 원통형 측면 상에 고르게 퍼지게 되는 상기 압축 둔부나사.
  11. 자물쇠 장치가 원통에 의해 형성된 홈과 한개의 부재에 의해 형성된 오목면으로 구성되는 청구범위 제10항의 압축 둔부나사.
  12. 하나의 부재가 그 말단에 홈이 파지고 오목면이 그 홈으로 부터 기부에 가까운 방향으로 뻗친 청구범위 제11항의 압축둔부 나사.
  13. 하나의 부재가 대퇴부 머리를 맞물고 있는 기부에 가까운 쪽 단부에서 나사선으로 되어 있고, 오목면이 그 나선으로 부터 공간이 형성되며 홈이 원통의 길이로 뻗어 있어서 그 원통의 길이에 걸쳐 핀을 설치하도록 되어 있고 이때 그 오목면을 한개 부재의 길이보다 더 짧은 길이로 제한하는 청구범위 제12항의 압축 둔부나사.
