연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

The hinge device according to claim 1, wherein said seat is cylindrical, said first and second portions of said seat are cylindrical, and said third and fourth portions of said regulating member are cylindrical. 3. The hinge device according to claim 1, wherein said fourth cylindrical portion has a maximum diameter substantially coinciding with a maximum diameter of said second cylindrical portion of said seat, said third cylindrical portion having a maximum diameter lower than a maximum diameter of the first cylindrical portion of said seat. 4. The hinge device according to claim 3, wherein said first and said second portions of the outer surface of said first regulating member have a respective first and second flat portions respectively opposite to said third and fourth portion such that, when said rod is in said rest position, said first and said second flat portions remain respectively faced to said first and said second openings, and when said rod is in said working position, said third and fourth cylindrical portions remain respectively faced to said first and said second openings so as to selectively obstruct the latter. 5. The hinge device according to claim 4, wherein said first and second flat portions have respective maximum widths lower than the respective maximum diameters of said third and fourth cylindrical portions. 6. The hinge device according to claim 1, wherein said regulating member includes an axial blind hole, said third and fourth cylindrical portions of said regulating member including a respective first and second pass-through hole in mutual fluid communication with said axial blind hole so that, when said rod is in said rest position, said second pass-through hole remains fluidly coupled with said second opening, and when said rod is in said working position, said second pass-through hole remains fluidly decoupled from said second opening so as to selectively obstruct said second opening, said first pass-through hole being configured to put in mutual fluid communication said first opening and said third opening through said channel regardless of whether the rod is in the rest position or in the working position. 7.
