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 latch mechanism, comprising: a latch rail formed with a first opening, a second opening and a cavity located in between said first and second openings, said latch rail being adapted to mount to a front wall of a truck box;a latch plate pivotally mounted to said latch rail, said latch plate being movable between a latched position and an unlatched position, said latch plate being adapted to engage a striker pin when in said latched position;a pawl lever pivotally mounted to said latch rail, said pawl lever being movable to a first position in which said pawl lever engages and retains said latch plate in said latched position, said pawl lever being movable to a second position in which said pawl lever releases said latch plate so that said latch plate can move from said latched position to said unlatched position;a first carriage located within said first opening of said latch rail and a second carriage located within said second opening of said latch rail;a first slide block and a second slide block each located within said cavity of said latch rail, said first slide block mounting a first actuator arm in position to engage said pawl lever, said second slide block mounting a second actuator arm in position to engage said pawl lever;a first actuator rod, said first actuator rod being fixed to said first carriage and fixed to said first slide block;a second actuator rod, said second actuator rod being fixed to said second carriage and fixed to said second slide block;said first carriage being movable in a first direction causing said first actuator rod to move said first slide block therewith, said first actuator arm mounted to said first slide block moving said pawl lever to said second position in response to movement of said first slide block in said first direction thus allowing said latch plate to move to said unlatched position;said second carriage being movable in a second direction, opposite to said first direction, causing said second actuator rod to move said second slide block therewith, said second actuator arm mounted to said second slide block moving said pawl lever to said second position in response to movement of said second slide block in said second direction thus allowing said latch plate to move to said unlatched position. 2. The latch mechanism of claim 1 in which said pawl lever mounts an actuator pin, each of said first and second actuator arms being mounted in position to engage said actuator pin, said first actuator arm when moving in said first direction with said first slide block being effective to cause said actuator pin to move said pawl lever out of engagement with said latch plate, said second actuator arm when moving in said second direction with said second slide block being effective to cause said actuator pin to move said pawl lever out of engagement with said latch plate. 3. The latch mechanism of claim 1 in which movement of said first slide block in said first direction and movement of said second slide block in said second direction causes said pawl lever to pivot. 4. The latch mechanism of claim 1 in which said first carriage mounts a key cylinder having an inner end extending into said first opening, a locking cap being mounted to said inner end of said key cylinder, said key cylinder being movable between a locked position wherein said locking cap prevents movement of said first carriage in said first direction and an unlocked position wherein said locking cap permits movement of said first carriage in said first direction. 5. The latch mechanism of claim 1 in which said second carriage mounts a key cylinder having an inner end extending into said second opening, a locking cap being mounted to said inner end of said key cylinder, said key cylinder being movable between a locked position wherein said locking cap prevents movement of said second carriage in said second direction and an unlocked position wherein said locking cap permits movement of said second carriage in said second direction. 6. The latch mechanism of claim 1 in which each of said first and second carriages mounts a finger tab which may be grasped by a user to move said first carriage in said first direction or said second carriage in said second direction. 7. A truck box, comprising: a front wall, a back wall, a bottom wall and opposed end walls interconnected to form a hollow interior, a lid movable between an open position and a closed position relative to said hollow interior, said lid mounting a striker pin;a latch mechanism, comprising: (i) a latch rail formed with a first opening, a second opening and a cavity located in between said first and second openings, said latch rail being mounted to said front wall of a truck box and extending substantially between said opposed end walls;(ii) a latch plate pivotally mounted to said latch rail, said latch plate being movable between a latched position and an unlatched position, said latch plate being effective to engage said striker pin when in said latched position;(iii) a pawl lever pivotally mounted to said latch rail, said pawl lever being movable to a first position in which said pawl lever engages and retains said latch plate in said latched position, said pawl lever being movable to a second position in which said pawl lever releases said latch plate so that said latch plate can move from said latched position to said unlatched position;(iv) a first carriage located within said first opening of said latch rail and a second carriage located within said second opening of said latch rail;(v) a first slide block and a second slide block each located within said cavity of said latch rail, said first slide block mounting a first actuator arm in position to engage said pawl lever, said second slide block mounting a second actuator arm in position to engage said pawl lever;(vi) a first actuator rod, said first actuator rod being fixed to said first carriage and fixed to said first slide block;(vii) a second actuator rod, said second actuator rod being fixed to said second carriage and fixed to said second slide block;(viii) said first carriage being movable in a first direction causing said first actuator rod to move said first slide block therewith, said first actuator arm mounted to said first slide block moving said pawl lever to said second position in response to movement of said first slide block in said first direction thus allowing said latch plate to move to said unlatched position;(ix) said second carriage being movable in a second direction, opposite to said first direction, causing said second actuator rod to move said second slide block therewith, said second actuator arm mounted to said second slide block moving said pawl lever to said second position in response to movement of said second slide block in said second direction thus allowing said latch plate to move to said unlatched position. 8. The latch mechanism of claim 7 in which movement of said first slide block in said first direction and movement of said second slide block in said second direction causes said pawl lever to pivot. 9. The latch mechanism of claim 7 in which said first carriage mounts a key cylinder having an inner end extending into said first opening, a locking cap being mounted to said inner end of said key cylinder, said key cylinder being movable between a locked position wherein said locking cap prevents movement of said first carriage in said first direction and an unlocked position wherein said locking cap permits movement of said first carriage in said first direction. 10. The latch mechanism of claim 7 in which said second carriage mounts a key cylinder having an inner end extending into said second opening, a locking cap being mounted to said inner end of said key cylinder, said key cylinder being movable between a locked position wherein said locking cap prevents movement of said second carriage in said second direction and an unlocked position wherein said locking cap permits movement of said second carriage in said second direction. 11. The latch mechanism of claim 7 in which each of said first and second carriages mounts a finger tab which may be grasped by a user to move said first carriage in said first direction or said second carriage in said second direction.
