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.

1. A hinge assembly comprising: a bracket installed on a main body;a shaft having a first portion rotatably supported by the bracket and a second portion providing a rotation center of a door that selectively opens and closes the main body;a transfer unit configured to transfer selectively rotatory power of the door to the shaft in order to move the shaft upward and downward; andan operating unit configured to selectively control the transfer unit by a user, wherein, when the operating unit is operated in a first state, the transfer unit is connected to the bracket and the rotary power of the door is transferred to the shaft to adjust the height of the door, and, when the operating unit is operated in a second state that is different than the first state, the transfer unit is disconnected from the bracket and the rotary power of the door is not transferred to the shaft. 2. The hinge assembly according to claim 1, wherein the transfer unit is connected selectively to the shaft according to the operation direction of the transfer unit. 3. The hinge assembly according to claim 1, wherein the transfer unit includes a plurality of levers moved by the operation of the operating unit and a plurality of elastic members supporting the respective levers. 4. The hinge assembly according to claim 3, further comprising: a rotating member coupled to the shaft, wherein according to the operation direction of the operating unit, the plurality of levers are spaced from the rotating member, or any one of the plurality of levers is spaced from the rotating member and the other one thereof is contacted to the rotating member. 5. The hinge assembly according to claim 4, wherein when the door rotates in a state where the plurality of levers are spaced from the rotating member, the door rotates with respect to the rotating member, and when the door rotates in a state where any one of the plurality of levers contacts the rotating member, the rotating member rotates with the door. 6. The hinge assembly according to claim 4, wherein a plurality of gear teeth are formed along the circumference of the rotating member, and hooking parts selectively positioned in the valleys formed between adjacent two gear teeth are formed in the respective levers. 7. The hinge assembly according to claim 3, wherein according to the operation direction of the operating unit, the plurality of levers are spaced from the shaft, or any one of the plurality of levers is spaced and the other thereof is contacted to the shaft. 8. The hinge assembly according to claim 7, wherein a plurality of gear teeth are formed along the circumference of the shaft, and hooking parts selectively positioned in the valleys formed between adjacent two gear teeth are formed in the respective levers. 9. A refrigerator comprising: a main body in which a storage chamber is formed;a door opening/closing the storage chamber; anda hinge assembly allowing the door to be rotatably connected to the body, wherein the hinge assembly comprises: a transfer unit transferring rotatory power selectively to the door;an operating unit configured to operate the transfer unit; anda shaft providing a rotation center of the door and movable upward and downward with respect to the body by the rotatory power of the door transferred by the transfer unit,wherein, when the operating unit is operated in a first state, the transfer unit is connected to the bracket and the rotatory power of the door is transferred to the shaft to adjust the height of the door, and, when the operating unit is operated in a second state that is different than the first state, the transfer unit is disconnected from the bracket and the rotatory power of the door is not transferred to the shaft. 10. The refrigerator according to claim 9, wherein the transfer unit includes a plurality of levers transferring the rotatory power of the door selectively to the shaft, and a plurality of elastic members supporting the respective levers. 11. The refrigerator according to claim 10, wherein the shaft rotates with the door when the door rotates in one direction in a state where any one of the plurality of levers contacts the shaft. 12. The refrigerator according to claim 11, wherein the door rotates with respect to the shaft when the door rotates in the other direction. 13. The refrigerator according to claim 11, wherein the door rotates with respect to the shaft in a state where the plurality of levers are spaced form the shaft. 14. The refrigerator according to claim 10, further comprising: a rotating member connected to the shaft to be rotatable with the shaft, and connected selectively to the plurality of levers. 15. A hinge assembly of a refrigerator comprising: a bracket;a shaft rotatably supported by the bracket and providing a rotation center of a door;a transfer unit transferring selectively rotatory power of the door to the shaft in order to move the shaft upward and downward; andan operating unit operating the transfer unit,wherein the transfer unit includes a plurality of levers moved by the operation of the operating unit and a plurality of elastic members supporting the respective levers. 16. The hinge assembly according to claim 15, further comprising: a rotating member coupled to the shaft, wherein according to the operation direction of the operating unit, the plurality of levers are spaced from the rotating member, or any one of the plurality of levers is spaced from the rotating member and the other one thereof is contacted to the rotating member. 17. The hinge assembly according to claim 16, wherein when the door rotates in a state where the plurality of levers are spaced from the rotating member, the door rotates with respect to the rotating member, and when the door rotates in a state where any one of the plurality of levers contacts the rotating member, the rotating member rotates with the door. 18. The hinge assembly according to claim 16, wherein a plurality of gear teeth are formed along the circumference of the rotating member, and hooking parts selectively positioned in the valleys formed between adjacent two gear teeth are formed in the respective levers. 19. The hinge assembly according to claim 15, wherein according to the operation direction of the operating unit, the plurality of levers are spaced from the shaft, or any one of the plurality of levers is spaced and the other thereof is contacted to the shaft. 20. The hinge assembly according to claim 19, wherein a plurality of gear teeth are formed along the circumference of the shaft, and hooking parts selectively positioned in the valleys formed between adjacent two gear teeth are formed in the respective levers.
