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 channel latch having a lock for holding the latch bolt closed which includes a secondary locking feature that prevents the lock from being turned. The lock mechanism has a tumbler barrel with a central reciprocal plunger that has a key portion which outwardly projects through the barrel into a keyway in the bolt. The plunger is depressed downward against a spring when a tool is inserted into the tumbler to turn it. The keyway includes longitudinal grooves and a pathway that restrict the upward release of the plunger only when the tumbler is turned to e...

1. A locking latch, comprising: a housing;a bolt affixed to the housing rotatable between open and closed positions;lock means located within a cylinder in the bolt for locking the bolt in the closed position, said lock means comprising a tumbler having a top, a bottom, and a barrel portion closely fitted within said cylinder, said tumbler selectively rotatable between locked and unlocked positions;a plunger located within a longitudinal bore of said tumbler barrel, said plunger axially reciprocal within said bore between a depressed and a released home position;a radially extending key integral with said plunger;a longitudinal slot in the side of the tumbler barrel through which the plunger key outwardly projects;a keyway in a sidewall of the bolt cylinder into which said key extends which restricts movement of the key, wherein only upon a maximum depression of the plunger is the tumbler barrel free to rotate between the locked and unlocked positions;means for engaging said housing on a bottom portion of the tumbler to lock the bolt closed; andwherein said keyway comprises a bottom most lateral arcuate portion and first and second longitudinal upwardly extending grooves. 2. The latch of claim 1 wherein said housing includes a recessed channel which receives said bolt when it is closed. 3. The latch of claim 1 wherein said tumbler barrel bore includes tool-engaging means for turning the barrel. 4. The latch of claim 3 wherein said plunger lies flush with a top of the tumbler barrel when the bolt is locked and the plunger is in the released home position. 5. The latch of claim 1 wherein the means for engaging said housing comprises two hooks that capture a housing cross-member. 6. The latch of claim 4 further including indicia on the top of the tumbler barrel for visually indicating its position of rotation. 7. The latch of claim 1 wherein said plunger is upwardly biased toward the released position by a spring. 8. The latch of claim 1 wherein the tumbler barrel is affixed to the bolt by capture between a flange at the top of the tumbler barrel and a retaining spring clip which engages the bolt cylinder sidewall. 9. The latch of claim 1 wherein said housing comprises two opposing side brackets joined by cross-members. 10. The latch of claim 9 wherein the bolt lies between the two side brackets and is rotatable about a roller on a rivet that joins said brackets. 11. The latch of claim 10 wherein the brackets include means for attachment to a panel. 12. The latch of claim 1 wherein the height of the second groove is lower than the first groove such that when the key is fully released within the second groove the top of the plunger lies sub-flush with the top of the barrel. 13. The latch of claim 12 wherein said tumbler barrel bore has a lateral hexagonal cross-section. 14. The latch of claim 1 wherein the bolt is locked when the key occupies the first groove and the bolt is closed. 15. The latch of claim 14 wherein when the key occupies the second groove the bolt is unlocked. 16. A locking latch, comprising: a housing;a bolt affixed to the housing rotatable between open and closed positions;lock means located within a cylinder in the bolt for locking the bolt in the closed position, said lock means comprising a tumbler having a top, a bottom, and a barrel portion closely fitted within said cylinder, said tumbler selectively rotatable between locked and unlocked positions;a plunger located within a longitudinal bore of said tumbler barrel, said plunger axially reciprocal within said bore between a depressed and a released home position;a radially extending key integral with said plunger;a longitudinal slot in the side of the tumbler barrel through which the plunger key outwardly projects;a keyway in a sidewall of the bolt cylinder into which said key extends which restricts movement of the key, wherein only upon a maximum depression of the plunger is the tumbler barrel free to rotate between the locked and unlocked positions;means for engaging said housing on a bottom portion of the tumbler to lock the bolt closed; andwherein the means for engaging said housing comprises two hooks that capture a housing cross-member. 17. A locking latch, comprising: a housing;a bolt affixed to the housing rotatable between open and closed positions;lock means located within a cylinder in the bolt for locking the bolt in the closed position, said lock means comprising a tumbler having a top, a bottom, and a barrel portion closely fitted within said cylinder, said tumbler selectively rotatable between locked and unlocked positions;a plunger located within a longitudinal bore of said tumbler barrel, said plunger axially reciprocal within said bore between a depressed and a released home position;a radially extending key integral with said plunger;a longitudinal slot in the side of the tumbler barrel through which the plunger key outwardly projects;a keyway in a sidewall of the bolt cylinder into which said key extends which restricts movement of the key, wherein only upon a maximum depression of the plunger is the tumbler barrel free to rotate between the locked and unlocked positions;means for engaging said housing on a bottom portion of the tumbler to lock the bolt closed; andwherein said plunger is upwardly biased toward the released position by a spring. 18. A locking latch, comprising: a housing;a bolt affixed to the housing rotatable between open and closed positions;lock means located within a cylinder in the bolt for locking the bolt in the closed position, said lock means comprising a tumbler having a top, a bottom, and a barrel portion closely fitted within said cylinder, said tumbler selectively rotatable between locked and unlocked positions;a plunger located within a longitudinal bore of said tumbler barrel, said plunger axially reciprocal within said bore between a depressed and a released home position;a radially extending key integral with said plunger;a longitudinal slot in the side of the tumbler barrel through which the plunger key outwardly projects;a keyway in a sidewall of the bolt cylinder into which said key extends which restricts movement of the key, wherein only upon a maximum depression of the plunger is the tumbler barrel free to rotate between the locked and unlocked positions;means for engaging said housing on a bottom portion of the tumbler to lock the bolt closed; andwherein the tumbler barrel is affixed to the bolt by capture between a flange at the top of the tumbler barrel and a retaining spring clip which engages the bolt cylinder sidewall.
