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.

A cylinder lock having a body and a modified cam, the cylinder lock being adapted for moving an external element arranged to engage the modified cam, so that the external element slides axially on the cylinder lock body. In a preferred embodiment, the inventive cylinder lock is designed to utilize a helical cam which engages a movable external element or slider, and this design is referred to as the HC cylinder lock. When operated by rotating the appropriate key within it, the movable external element can be moved in a linear fashion along the length of the HC cylinder lock thus converting rotational motion of the key to axial motion of the external element. The external element is arranged to engage an eccentric pin formed as part of a rotating bolt which rotates on an orthogonal axis to the cylinder plug in response to said sliding motion, for the function of locking or unlocking a device. The streamlined design of the inventive HC cylinder lock enables efficient placement of a door lock within the hollow volume of a door to provide locking action.

1. In a cylinder lock constructed as a body having at least one cylinder plug rotatably disposed therein, said at least one cylinder plug having both a key end and a non-key opposite end, the improvement comprising: a modified cam disposed at said cylinder plug non-key opposite end, said cam having at least one thread, said cylinder lock being adapted for moving an external element arranged to engage said modified cam, said external element being arranged to slide along said cylinder lock body at least partially between said key end and said non-key opposite end upon rotation of said at least one cylinder plug, wherein said external element is linked to a rotating bolt which rotates in response to said sliding motion of said external element, to provide a locking action. 2. The cylinder lock of claim 1, wherein said rotating bolt rotates on an axis orthogonal to said at least one cylinder plug rotation. 3. The cylinder lock of claim 1, wherein said modified cam comprises a plurality of helical-shaped threads. 4. The cylinder lock of claim 3, wherein said external element has formed therein a threaded groove matching said helical thread section formed on said modified cam, thereby providing said engagement of said external element and said modified cam. 5. A door locking mechanism utilizing the cylinder lock of claim 1, provided with a locking hasp for locking engagement of said rotating bolt therewith, said locking hasp being mounted on an external entrance side of a door, with said door locking mechanism being operable by the cylinder lock from either side of the door. 6. The door locking mechanism of claim 5 wherein said locking engagement of said rotating bolt and said locking hasp provides multi-directional security against tampering. 7. The door locking mechanism of claim 5, wherein said door locking mechanism is encased and protected from all sides to prevent attempted intrusion. 8. The door locking mechanism of claim 5, wherein said door locking mechanism is provided with a patterned edge which engages a patterned edge of said locking hasp, to prevent forced intrusion. 9. A door locking mechanism utilizing the cylinder lock of claim 1, further comprising a spacer element for supporting the internal structure of a hollow metal door, placed within said internal structure of said door as part of the door production at the factory or at an installation site thereof, said spacer element enabling proper tightening of mounting screws of said door locking mechanism seated within said door via a hole formed in said door proximate to said spacer element, without deforming the door profile, and providing a strong mechanical connection with the door structure, thus strengthening the mounting area of said door locking mechanism. 10. The door locking mechanism of claim 9, wherein the spacer element is designed for insertion within said internal structure of the hollow metal door via said hole formed as a main mounting hole prepared for the insertion of said locking mechanism. 11. The door locking mechanism of claim 10, wherein the spacer element is formed with protrusions on each of both ends, and shoulders, such that when the spacer is inserted through said main mounting hole, a first protrusion is inserted in an auxiliary mounting hole, which serves as an anchor point, enabling snap-fit of a second protrusion to complete the mounting. 12. The door locking mechanism of claim 10, wherein the spacer element has been inserted within said internal structure of the hollow metal door by a method incorporating use of a standard, flat screwdriver which engages a specially-designed slot formed in said spacer element as it is placed through said hole, thereby preventing said spacer element from falling within the door interior during installation. 13. The door locking mechanism of claim 10, wherein said protrusions of the spacer element are formed so as to create friction with said door internal structure, thereby maintaining said spacer element in a desired orientation. 14. In a cylinder lock constructed as a body having at least one cylinder plug rotatably disposed therein, said at least one cylinder plug having both a key end and a non-key opposite end, wherein the improvement comprises: a modified cam disposed at said cylinder plug non-key opposite end, said cam having at least one thread, a method of operating said cylinder lock comprising: providing an external element shaped to engage said cam, and rotating said cylinder plug by an appropriate key, such that said external element slides along said cylinder lock body at least partially between said key end and said non-key opposite end upon rotation of said at least one cylinder plug wherein said external element is arranged to engage an eccentric pin formed as part of a rotating bolt which rotates in response to said sliding motion of said external element, to provide a locking action. 15. A high-security rotating bolt lock comprising a cylinder lock constructed as a body having at least one cylinder plug rotatably disposed therein, said at least one cylinder plug having both a key end and an opposite end, said rotating bolt lock further comprising: a modified cam disposed at said; at least one cylinder plug opposite end, said cam having at least one thread, said cylinder lock being adapted for moving an external element arranged to engage said modified cam, said external element being arranged to slide along said cylinder lock body at least partially between said key end and said opposite end upon rotation of said at least one cylinder plug wherein said external element is arranged to engage an eccentric pin formed as part of a rotating bolt which rotates in response to said sliding motion of said external element, to provide a locking action.
