본 고안은 도어를 잠그거나 여는데 사용되는 도어용 잠금장치에 관한 것으로, 특히, 본 고안은 도어 안쪽에 매설되어, 도어내부에서는 사람이 손으로 잠그거나 열 수 있고, 도어외부에서는 사람이 열쇠를 사용하여 도어를 잠그거나 여는데 사용되는 도어용 잠금장치에 관한 것이다.The present invention relates to a lock for a door used to lock or open the door, in particular, the present invention is embedded in the door, the inside of the door can be locked or opened by the hand, the outside of the door by the person A locking device for a door used to lock or open the door by use.

종래의 도어용 잠금장치는 제1도에 도시한 바와같이, 케이스(30)와 케이스(30)로부터 돌출이 가능하도록 설치되는 고정쇠부(29)와, 케이스(30)에서 돌출이 가능하도록 설치되고, 후단부에 핀을 가진 걸림쇠부(20)로 구성되어 있고, 상기 고정쇠부(29)는 고정쇠(32)와 고착되는 고정쇠 조작편(31)과, 고정쇠 조작편(31)를 앞뒤로 이동시키는 고정쇠 구동암(33)으로 구성되어 있고, 상기 걸림쇠부(20)는 걸림쇠(21)와, 걸림쇠(21)와 고착되는 걸림쇠 조작편(22)과, 걸림쇠 조작용 손잡이(도시되지 않았음)이 작동에 의하여 상승하고, 상승했을 때 상기 걸림쇠 조작편(22)의 핀(26)을 후방으로 밀어주는 테이퍼 형상 구동부(24)를 가지는 상·하작동판(23)으로 구성되어 있다.As shown in FIG. 1, the conventional lock device for the door is provided to allow the protrusion 30 to protrude from the case 30 and the case 30, and to protrude from the case 30. And a latch portion 20 having a pin at a rear end thereof, and the latch portion 29 includes a clamp operation piece 31 fixed to the clamp 32 and a clamp for moving the clamp operation piece 31 back and forth. It consists of a drive arm 33, the latch portion 20, the latch 21, the latch operation piece 22 is fixed to the latch 21, and the handle (not shown) for the latch operation is operated It is comprised by the up-and-down operation board 23 which has a taper-shaped drive part 24 which raises | hangs and pushes the pin 26 of the said latch operation piece 22 back when it raises.

종래의 도어용 잠금장치의 작동상태를 살펴보면 다음과 같다.Looking at the operation of the conventional door lock device are as follows.

고정쇠 구동암(33) 중앙에 천공된 고정쇠 구동암 조작공(35)에 고정쇠 구동암 조작간을 집어 넣고 좌·우로 돌려서 고정쇠 구동암(33)과 접촉되어 있는 고정쇠 조작편(31)을 앞·뒤로 이동시키면 상기 고정쇠(32)도 앞·뒤로 이동되어 잠기거나 풀리게 된다.Insert the detent drive arm operation part into the detent drive arm operation hole 35 drilled in the center of the detent drive arm 33, and turn the detent operation piece 31 which is in contact with the detent drive arm 33 by turning left and right. When moving backward, the clamp 32 is also moved back and forth to lock or unlock.

또한, 걸림쇠 조작용 손잡이(도시되지 않았음)에 의하여 상·하작동판(23)을 상·하로 작동시키면 걸림쇠 조작편(22)에 고착된 핀(26)이 상·하 작동판(23)의 테이퍼 형상 구동부(24)에 접촉되어 전·후진되므로써 상기 걸림쇠(21)가 앞뒤로 작동된다.In addition, when the upper and lower operating plates 23 are operated up and down by the latch operation knobs (not shown), the pins 26 fixed to the latch operating pieces 22 are connected to the upper and lower operating plates 23. The latch 21 is operated back and forth by contacting the tapered drive part 24 forward and backward.

상기한 바와같이, 걸림쇠(21)가 후진할 경우 걸림쇠 조작편(22)에 고착된 핀(26)이 아래방향 한쪽 방향에서만 편심하중을 받고 핀(26)의 원주면과 상·하작동판(23)의 테이퍼 형상 구동면의 마찰로 인하여 걸림쇠(21)가 뒤쪽으로 원활하게 이동하지 못하는 문제점이 있었고, 상·하작동판(23)에 작용하는 하중이 제거됨으로써 상하작동판(23)이 아래방향으로 원위치되어 걸림쇠(21)가 앞으로 전진할 경우에도 기구의 작동상태는 상기한 바와같은 문제점이 있었다.As described above, when the latch 21 is retracted, the pin 26 fixed to the latch operating piece 22 receives an eccentric load in only one direction in the downward direction, and the circumferential surface of the pin 26 and the upper and lower operating plates 23. Due to the friction of the tapered driving surface of the), the latch 21 does not move smoothly to the rear, and the upper and lower operating plates 23 are moved downward by removing the load acting on the upper and lower operating plates 23. Even when the original position and the latch 21 is moved forward, the operation state of the mechanism had the problem as described above.

따라서, 본 고안은 상기한 바와같은 문제점을 해결하기 위하여 걸림쇠(21)가 케이스(30) 내·외부로 원활하게 전진 또는 후진하도록 하는 걸림쇠 기구의 제공을 목적으로 한다.Therefore, an object of the present invention is to provide a clasp mechanism for smoothing the clasp 21 forward or backward into and out of the case 30 in order to solve the above problems.

본 고안을 첨부도면(제2도 및 제3도)에 의하여 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings (FIGS. 2 and 3).

케이스(30)와, 고정쇠부(29)와, 걸림쇠부(1)로 구성된 도어용 잠금 장치에 있어서, 상기 걸림쇠부(1)는 상·하로 운동하는 상·하작동판(5)과, 힌지(12)로 고정되어 상·하작동판(5)의 상·하운동에 의하여 좌·우로 미소 회전하는 회전조작판(4)과, 회전조작판(4)의 회전에 의하여 전·후진하는 걸림쇠 조작편(3)으로 구성되어 있다.In the door lock device which consists of the case 30, the clamping part 29, and the latching part 1, the said latching part 1 is an up-and-down operating plate 5 which moves up and down, and a hinge ( 12) the rotating operation plate 4 which rotates slightly to the left and right by the up and down movement of the upper and lower operation plates 5, and the latch operation piece that moves forward and backward by the rotation of the rotation operation plate 4; It consists of (3).

또한, 상기 상·하작동판(5)은 좌측하단에 형성된 돌출부(8)와 그 돌출부(8)에 장착된 인장코일스프링(11)으로 구성되어 있으며, 상기 회전조작판(4)은 중앙상부를 고정하는 힌지(12)와 좌측하단부에 형성된 돌출부(7)와 우측상단부에 형성된 돌출부(6)로 구성되어 있으며, 상기 상·하작동판(5)과 회전조작판(4)과 걸림쇠 조작편(3)은 각 돌출부가 맞물리어 연동되는 구조로 되어 있다.In addition, the upper and lower operating plate (5) is composed of a protrusion (8) formed on the lower left end and a tension coil spring (11) mounted on the protrusion (8), the rotary operating plate (4) is the upper center It consists of a hinge (12) to be fixed and a protrusion (7) formed in the lower left end and a protrusion (6) formed in the upper right end, the upper and lower operating plate (5), the rotary operation plate (4) and the clasp operation piece (3). ) Is a structure in which each protrusion is engaged with each other.

제3도에 도시한 바와같이 본 고안의 작동상태를 설명하면 다음과 같다.Referring to Figure 3 when explaining the operating state of the subject innovation as follows.

상기 걸림쇠 조작용 손잡이를 돌리면 그 손잡이와 연결된 상·하작동판(5)이 상승하고, 상·하작동판(5)이 상승함과 동시에 상·하작동판(5) 하부에 형성된 돌출부(8)에 맞물려 회전조작판(4)이 우측으로 걸림쇠(2) 후진거리만큼 미소 회전하며, 회전조작판(4)하부에 형성된 돌출부(7)에 맞물려 있는 걸림쇠 조작편(3)이 뒤로 이동된다. 다시 걸림쇠 조작용 손잡이를 원위치로 놓으면 그 손잡이와 연결된 상·하작동판(5)에 하중이 작용하지 않으므로 상·하작동판(5) 하부에 설치된 인장코일스프링(8)의 복원력에 의하여 상·하작동판(5)이 하강하고, 상·하작동판(5)과 맞물려 있는 회전조작판(4)이 좌로 회전하며, 회전조작판(4)에 맞물려 있는 걸림쇠 조작편(3)이 전진하여 걸림쇠(2)가 케이스(30)밖으로 돌출된다.When the claw operation knob is turned, the upper and lower operating plates 5 connected to the handle are raised, the upper and lower operating plates 5 are raised, and are engaged with the protrusions 8 formed at the lower and upper operating plates 5, respectively. The rotary operating plate 4 rotates slightly to the right by the latch 2 reverse distance, and the latch operating piece 3 engaged with the protrusion 7 formed under the rotary operating plate 4 is moved backward. If the handle for restraint is returned to the original position, no load acts on the upper and lower operating plates (5) connected to the handles, so that the upper and lower operating plates are restrained by the restoring force of the tension coil spring (8) installed under the upper and lower operating plates (5). (5) is lowered, the rotary operating plate (4) engaged with the upper and lower operating plate (5) rotates to the left, and the latch operating piece (3) engaged with the rotary operating plate (4) moves forward and the latch (2) Protrudes out of the case 30.

상기한 바와같이 구성된 본 고안은 종래의 도어용 잠금장치와 비교하여, 회전조작판(4)의 좌·우측방향의 미소회전에 의하여 걸림쇠 조작편(3)을 일직선상으로 잡아당기거나 놓아줌으로써 걸림쇠 조작편(3)이 원활하게 전·후진할 수 있도록 하여 걸림쇠 조작편(3)에 고착된 걸림쇠(2)의 전·후진 동작을 안정화시켜 도어용 잠금장치의 신뢰성을 제고해 주는 효과가 있다.Compared with the conventional door lock device, the present invention configured as described above has a latch by pulling or releasing the latch operation piece 3 in a straight line by a small rotation in the left and right directions of the rotary operation plate 4. By allowing the operation piece 3 to move forward and backward smoothly, it is effective to stabilize the forward and backward operation of the latch 2 secured to the latch operation piece 3, thereby improving the reliability of the door locking device.
