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 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 refrigerator appliance comprising: a cabinet having a temperature-controlled compartment defined therein;a shelf ladder disposed in the temperature-controlled compartment and providing a plurality of shelf mounting positions;a housing comprising an electrical connector;a lever assembly comprising:a first lever hingedly attached to the electrical connector and comprising an electrical contact and a distal end; anda second lever hingedly attached to the electrical connector comprising a first end slidably coupled to the distal end of the first lever;a spring disposed on the shelf ladder in contact with the lever assembly;an adjustable shelf comprising a bracket with an upper tab and a lower tab, the lower tab further comprising an electrical conductor, the adjustable shelf removably mountable in one of the plurality of shelf mounting positions;wherein the lower tab is configured to interface with the lever assembly such that the lower tab forces the second lever and the first lever into an engaged position such that the electrical contact is electrically coupled to the electrical conductor. 2. The refrigerator appliance of claim 1, wherein the spring is in contact with the second lever. 3. The refrigerator appliance of claim 2, wherein the spring is fixedly attached to the electrical connector. 4. The refrigerator appliance of claim 1, wherein the spring is a helical spring. 5. The refrigerator appliance of claim 1, wherein a first surface of the lower tab is configured to interface with the second lever and a second surface of the lower tab that is configured to interface with the electrical conductor are perpendicular to one another. 6. The refrigerator appliance of claim 1, wherein the lower tab of the bracket includes at least two electrical contacts configured to interface with at least two electrical conductors on the first lever. 7. An electrical connector for an adjustable refrigerator shelf, the electrical connector comprising: a first lever having a first end and a second end, the first lever being rotatable from a disengaged position to an engaged position;a second lever having a first section and a second section, the second lever being rotatable from a disengaged position to an engaged position in which a first electrical contact carried by the second section engages a shelf mounting bracket to supply power to the adjustable refrigerator shelf; anda spring that biases at least one of the first lever and the second lever toward the disengaged position;wherein the first end of the first lever is slidably coupled to the first section of the second lever such that movement of the first lever from the disengaged position to the engaged position causes movement of the second lever from the disengaged position to the engaged position. 8. The electrical connector of claim 7, further wherein the spring biases the first lever toward the disengaged position. 9. The electrical connector of claim 7, wherein the first end of the first lever includes a protrusion extending therefrom which engages a track formed in the first section of the second lever. 10. The electrical connector of claim 7, wherein: a housing supporting the electrical connector is coupled to a shelf ladder having a slot formed therein; andthe first electrical contact carried by the second section of the second lever is configured to interface with a first conductor carried by a tab of the shelf mounting bracket that extends through the slot when the shelf mounting bracket is cantilevered on the shelf ladder. 11. The electrical connector of claim 10, further comprising a second electrical contact carried by the second section of the second lever, the second electrical contact being configured to interface with a second conductor carried by the tab when the shelf mounting bracket is cantilevered on the shelf ladder. 12. The electrical connector of claim 11, wherein the first and second electrical contacts are configured to supply power to the adjustable refrigerator shelf at different current levels. 13. The electrical connector of claim 10, wherein: the first lever is pivotably coupled to the housing at the second end of the first lever; andthe second lever is pivotably coupled to the housing at a location where the first and second sections of the second lever meet. 14. A domestic appliance comprising: a cabinet;a shelf ladder within the cabinet and providing a plurality of shelf mounting positions;a housing having an electrical connector;a lever assembly having a first lever hingedly coupled to the electrical connector having an electrical contact and a distal end, and a second lever hingedly coupled to the electrical connector having a first end slidably coupled to the distal end of the first lever;a spring disposed on the shelf ladder in contact with the lever assembly;a shelf having a bracket with an upper tab and a lower tab, the lower tab having an electrical conductor, the shelf removably mountable in one of the plurality of shelf mounting positions;wherein the shelf has an installed position, whereby the lower tab forces the first lever and the second lever into a connected position, and whereby the electrical contact is in electrical communication with the electrical conductor. 15. The domestic appliance of claim 14, wherein the spring is in contact with the second lever. 16. The domestic appliance of claim 14, wherein the spring is fixedly attached to the electrical connector. 17. The domestic appliance of claim 14, wherein the spring is a helical spring. 18. The domestic appliance of claim 14, wherein a first surface of the lower tab is configured to interface with the second lever and a second surface of the lower tab that is configured to interface with the electrical conductor are perpendicular to one another. 19. The domestic appliance of claim 14, wherein the lower tab of the bracket includes at least two electrical contacts configured to interface with at least two electrical conductors on the first lever. 20. The domestic appliance of claim 19, wherein the at least two electrical contacts are configured to supply power to the shelf at different current levels.
