It is composed of a locker (4) installed so as to form a locking portion (4a) at the upper end thereof, and an open button (5) protrudingly installed in front of the guider (1) to selectively rotate the locker (4).

이러한 종래 록킹장치는 화물칸 도어의 폐쇄 상태에서는 록커(4)의 걸림부(4a)가 도시되지 않은 화물칸 내측의 스트라이커(striker)에 걸림고정되어 잠금상태를 유지하고, 화물칸 도어의 개방을 위해 개방버튼(5)을 눌러줄 경우에는 록커(4)가 힌지축(3)을 기점으로 안내핀(2)에 의해 미끄럼 안내되면서 회동하여 그 걸림부(4a)가 스트라이크로부터 이탈되도록 함으로써 개방이 이루어지게 되어 있다.This conventional locking device is locked in the locker (4) of the locker (4) inside the cargo compartment not shown in the closed state of the cargo compartment door is locked to maintain a locked state, the opening button for opening the cargo compartment door In the case of pressing (5), the locker 4 is rotated while being guided by the guide pin 2 from the hinge shaft 3 to rotate so that the locking portion 4a is released from the strike. have.

그런데, 상기한 종래 록킹장치는 록커(4)의 회동 개폐시에 안내핀(2)이 고정부(1a)에 형성시킨 슬로트 홀(Slot Hole)에서 미끄럼 이동하며 록커(4)의 회동을 안내하게 되는 구조적 문제점으로 인해 잦은 고장이 유발되고, 장기 사용시에 먼지등의 외부이물질이 유입누적될 경우 록킹장치로서의 기능을 상실하게 되어 유지보수에 많은 노력이 요구되는 등의 여러가지 문제점들이 지적되고 있다.However, the above-described conventional locking device slides in the slot hole formed by the guide pin 2 in the fixing portion 1a when the locker 4 is rotated and opened and guides the rotation of the locker 4. Frequent failures are caused by structural problems, and when foreign matters such as dust accumulate during long-term use, various functions such as loss of function as a locking device are lost and much effort is required for maintenance.

본 고안은 상기한 문제점들을 적극적으로 해소시킬 수 있는 대형버스의 화물칸 도어용 록킹장치를 제공함에 그 목적이 있는바, 이하에서 본 고안의 바람직한 실시예를 첨부도면에 의해 상세히 설명한다.The present invention is intended to provide a locking device for a cargo compartment door of a large bus that can actively solve the above problems, will be described in detail with reference to the accompanying drawings, preferred embodiments of the present invention.

본 고안은 제2도에서와 같이, 도시되지 않은 화물칸 도어에 고정설치되며 그 내측에 고정부(6a)를 형성시킨 브라켓트(6)와, 그 대략 중앙에 안내장공(7a)을 구비하여 상기 고정부(6a)에 안내축(8)으로 유동가능하게 고정설치되며 그 양측에는 걸림홈(7b)과 연결부(7c)를 형성시킨 록커(7)와, 상기 연결부(7c)에 지지부(9a)가 연결축(10)으로 이음되고 그 타측에는 고정부(6a)의 고정축(11)을 따라 이동하는 이동홈(9b)을 형성시킨 연결부재(9)와, 상기 지지부(9a)와 고정축(11) 사이에 탄압설치되어 연결부재(9)에 인장력을 부여하는 탄성부재(12)로 구성된다.The present invention, as shown in Figure 2, is fixed to the cargo compartment door (not shown) and provided with a bracket (6) having a fixing portion (6a) in the inside, and a guide hole (7a) in the center of the high The locker 7 which is fixedly installed to the government 6a by the guide shaft 8 and which has the locking groove 7b and the connection part 7c is formed on both sides, and the support part 9a is provided in the said connection part 7c. A connecting member 9 formed with a connecting groove 10b connected to the connecting shaft 10 and having a moving groove 9b moving along the fixed shaft 11 of the fixed portion 6a on the other side, and the supporting portion 9a and the fixed shaft ( 11) is provided between the elastic member 12 is provided between the pressure is applied to the connecting member 9 in the tension.

도면중 미설명부호(13)은 화물칸 내측에 고정설치된 스트라이커이고, (14)는 연결축(10)의 분리방지를 위한 E링이다.In the drawings, reference numeral 13 is a striker fixedly installed inside the cargo compartment, and 14 is an E ring for preventing separation of the connecting shaft 10.

이와같은 구성의 본 고안은 화물칸 도어의 폐쇄 상태에서는 제2도(a)에서와 같이 록커(7)의 걸림홈(7b)에 화물칸의 스트라이커(13)가 삽입(걸림)된 상태를 유지하게 되므로 화물칸 도어는 록킹상태로서 개방이 방지된다.The present invention of such a configuration keeps a state in which the striker 13 of the cargo compartment is inserted (locked) in the locking groove 7b of the locker 7 as in FIG. 2 (a) in the closed state of the cargo compartment door. The cargo door is locked and prevented from opening.

이때 록커(7)는 그 대략 중앙의 안내장공(7a)에 삽입된 안내축(8)을 힌지로 하여 반시계방향회동 즉, 걸림상태 해지가 방지되는데, 이는 그 연결부(7c)에 지지부(9a)를 연결축(10)으로 연결시킨 연결부재(9)가 탄성부재(12)의 가압인장력을 시계방향으로 부여하고 있음에 기인한다.At this time, the locker 7 prevents counterclockwise rotation, that is, the termination of the locked state, by using the guide shaft 8 inserted into the guide hole 7a at the center thereof as a hinge, which is supported by the connecting portion 7c. The connecting member 9, which is connected to the connecting shaft 10, is applied to the pressing member of the elastic member 12 in the clockwise direction.

따라서 록커(7)는 안내축(8)을 기점으로 하여 시계방향 인장력으로 브라켓트(6)와 가압밀착된 상태를 유지하게 되므로 화물칸 도어의 견고한 잠금상태를 유지시킴과 동시에 차량 주행시 부여되는 진동에 의한 스트라이커(13)와 걸림홈(7b) 사이의 마찰소음도 방지하게 된다.Therefore, the locker 7 maintains the tight contact with the bracket 6 by the clockwise tensile force starting from the guide shaft 8, thereby maintaining a firm locking state of the cargo compartment door, Friction noise between the striker 13 and the locking groove 7b is also prevented.

한편 제2도(b)에서는 본 고안 록킹장치가 잠금해지 상태로 전환된 화물칸 도어의 개방초기 상태를 나타낸 것으로, 제2도(a)의 상태에서 화물칸 도어에 개방을 위한 인장력을 가하게 되면, 브라켓트(6)도 화물칸 도어와 함께 도면상 하향이동하게 된다.On the other hand, Figure 2 (b) shows the opening state of the cargo compartment door in which the lock device of the present invention is switched to the unlocked state, when a tension force for opening the cargo compartment door in the state of Figure 2 (a), the bracket (6) is also moved downward in the drawing with the cargo door.

상기한 브라켓트(6)의 하향이동시에 스트라이커(13)는 화물칸에 고정된 상태이므로 록커(7)는 걸림홈(7b)에 의해 스트라이커(13)로부터 반시계 방향의 회동력을 부여받게 된다.Since the striker 13 is fixed to the cargo compartment during the downward movement of the bracket 6, the locker 7 is provided with a counterclockwise rotation force from the striker 13 by the locking groove 7b.

따라서 록커(7)는 안내축(8)을 중심으로 반시계 방향으로 회동하게 되고, 이에 따라 연결부(7b)는 도면상 하향 회동하여 연결축(10)이 안내축(8)과 고정축(11) 사이를 연결하는 중심선상으로 이동하게 되는데, 이러한 작동진행시에 연결부재(9)는 그 이동홈(9b)이 고정축(11)에 안내되며 좌측으로 이동하게 되므로 탄성부재(12)는 가압수축된 상태가 된다.Therefore, the rocker 7 rotates counterclockwise around the guide shaft 8. As a result, the connecting portion 7b rotates downward in the drawing so that the connecting shaft 10 is connected to the guide shaft 8 and the fixed shaft 11. ) Is moved on the center line connecting between, the connection member (9) during this operation is the moving groove (9b) is guided to the fixed shaft (11) and moved to the left because the elastic member 12 is pressed It is in a contracted state.

상기한 연결부재(9)의 좌측이동과 탄성부재(12)의 가압수축은 안내축(8)과 연결축(10) 및 고정축(11)이 일직선상에 위치할 때에 최대 상태가 되며 개방이 더욱 진행되어 연결축(10)이 안내축(8)과 고정축(7)을 연결하는 중심선으로부터 하향이동하게 되면, 이때에는 탄성부재(12)의 가압인장력을 부여 받는 연결부재(9)가 록커(7)의 연결부(7c)를 보여주게 되므로 록커(7)는 안내축(8)을 중심으로 급격히 반시계 방향으로 회동하여 제2도(b)의 상태가 된다.The left side movement of the connecting member 9 and the pressure contraction of the elastic member 12 are at a maximum when the guide shaft 8, the connecting shaft 10, and the fixed shaft 11 are located in a straight line. Further, when the connecting shaft 10 moves downward from the center line connecting the guide shaft 8 and the fixed shaft 7, the connecting member 9, which receives the pressing force of the elastic member 12, becomes a locker. Since the connection part 7c of (7) is shown, the locker 7 turns to counterclockwise abruptly about the guide shaft 8, and will be in the state of FIG.

상기 작동은 화물칸 도어의 개방과 동시에 순간적으로 완료되며, 이러한 잠금해지 상태에서는 록커(7)의 걸림홈(7b)이 상향 개구되어 스트라이커(13)가 완전히 이탈되므로 화물칸 도어에 대한 구속은 해지된다.The operation is instantaneously completed at the same time as the opening of the cargo compartment door. In this unlocked state, the locking groove 7b of the locker 7 is upwardly opened so that the striker 13 is completely released and the restraint on the cargo compartment door is released.

한편, 화물칸 도어의 폐쇄시에는 록커(7)의 걸림홈(7b)이 스트라이커(13)에 의해 시계방향으로 회동하게 되므로 상기의 역순에 의해 제2도(a)에서와 같은 폐쇄상태로 전환된다.On the other hand, when the cargo compartment door is closed, the locking groove 7b of the locker 7 is rotated clockwise by the striker 13, so that the reverse direction is switched to the closed state as shown in FIG. .

이와같이 본 고안 록킹장치는 구성부품이 외부로 노출되지 않으면서도 견고한 잠금상태의 유지와 주행중 소음발생을 최소화 할 수 있고, 먼지등 이물에 의한 기능상실 우려가 해소되어 유지관리 및 조작이 용이함은 물론, 작동신뢰성 향상에 의해 제품의 수명을 연장시킬 수 있는 등의 효과가 있다.In this way, the lock device of the present invention can minimize the occurrence of noise while driving while maintaining a firm locking state without exposing the components to the outside, and it is easy to maintain and operate as the risk of malfunction due to foreign matter such as dust is eliminated. By improving the operation reliability, it is possible to prolong the life of the product.
