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.

초록

A vent assembly has a locking mechanism to retain its cover on its base. The locking mechanism includes a latch and linkage coupled with the latch to move the latch between a locked and an unlocked position. A post member extends from the cover to cooperate with the latch such that in a locked condition, the cover is locked with the base in a closed position. When the latch is moved to a second position, the cover is enabled to pivot away from the base to an open position.

What is claimed is: 1. A vent assembly with a cover locking mechanism comprising: a base; a cover movably coupled with said base between an open and closed position; a locking mechanism associated with said base, said locking mechanism including a latch and a linkage coupled with said latch for moving the latch between a locked and an unlocked position and a member extending from said cover, said latch including a stop, said member having a surface for cooperating with said latch stop such that when in a locked condition, said stop exerts a force on said member surface for locking the latch in a retained position so that said cover is locked with said base in said closed position and when in an unlocked condition said cover is enabled to pivot away from said base into said open position, wherein said latch is a hook shape comprising an extending end and an opening defined between said extending end and the main body of said hook, wherein said extending arm includes a ramp at one end and an end tapered surface extending away from said ramp, said stop formed at the junction of the end tapered surface and ramp surface so that said stop forms a biting line contact into the surface of the member extending from the cover. 2. The vent assembly with a cover locking mechanism of claim 1, wherein said member is a post having a head extending from said cover. 3. The vent assembly with a cover locking mechanism of claim 2, wherein said post is unitarily formed with said cover. 4. The vent assembly with a cover locking mechanism of claim 1, wherein said linkage has two ends, said latch secured at one said end and a handle at the other end. 5. The vent assembly with a cover locking mechanism of claim 1, wherein said cover member includes a planar surface for contacting said ramp. 6. The vent assembly with a cover locking mechanism of claim 1, wherein said linkage includes a rotatable rod coupled with said latch. 7. A locking mechanism for a vent assembly including a base and a cover comprising: a latch and a linkage coupled with said latch for moving the latch between a locked and an unlocked position and a member extending from the cover, said latch including a stop, said member having a surface for cooperating with said latch stop such that when in a locked condition said stop exerts a force on said member surface for locking the latch in a retained position so that the cover is locked with the base in a closed position and when in an unlocked condition the cover is enabled to pivot away from the base to an open position, wherein said latch is a hook comprising an extending end and an opening defined between said extending end and the main body of said hook, wherein said extending arm includes a ramp at one end and an end tapered surface extending away from said ramp, said stop formed at the junction of the end tapered surface and ramp surface so that said stop forms a biting line contact into the surface of the member extending from the cover. 8. The locking mechanism of claim 7, wherein said member is a post having a head extending from the cover. 9. The locking mechanism of claim 8, wherein said post is unitarily formed with said cover. 10. The locking mechanism of claim 7, wherein said linkage has two ends, said latch at one said end and a handle at the other end. 11. The locking mechanism of claim 7, wherein said cover member includes a planar surface for contacting said ramp. 12. The locking mechanism of claim 7, wherein said linkage includes a rotatable rod coupled with said latch. 13. A vent assembly with a two point cover retention mechanism comprising: a base; a cover movably coupled with said base between an open and closed position; a locking mechanism associated with said base, said locking mechanism including a latch and a linkage coupled with said latch for moving the latch between a locked and an unlocked position and a member extending from said cover, said member cooperating with said latch such that when in a locked condition said cover is locked with said base in a closed position and when in an unlocked condition said cover is enabled to pivot away from said base to said open position, wherein said latch has a hook shape comprising an extending end and an opening defined between said extending end and the main body of said hook, wherein said extending arm includes a ramp at one end and an end tapered surface extending away from said ramp, a stop is formed at the junction of the end tapered surface and ramp surface so that said stop forms a biting line contact into the surface of the member extending from the cover to exert a force on a surface of said member for locking said latch in a retained position with respect to said member; an arm coupled with said cover, said arm raising and lowering for moving said cover between said open and closed position, said arm positioned adjacent one side of said base, said locking mechanism positioned on an opposite side of said base from said arm.
