본 고안은 실린더형 도어록에 있어서,The present invention is a cylindrical door lock,

도어록이 잠겨져 있을때 외부레바를 젖혀 문을 열려고 하면 잠겨져있지 않을때와 마찬가지로 레바가 일정각도 회전하면서도 문이 열리지 않도록 함으로써 잠겨진 도어록을 무리하게 작동시킴으로 인한 도어록의 훼손 및 고장을 예방하기 위한 것이다.When the door lock is locked and tries to open the door by flipping the outer lever, the lever is rotated at an angle so that the door does not open by preventing the door lock from being damaged or broken by forcibly operating the locked door lock.

주지된 바와같이 일반적인 실린더형 도어록은 내부에서 잠금보턴을 누르면 외부레버가 젖혀지지 않도록 구성함으로써 외부에서는 문을 열수 없도록 한 것인데, 잠겨진 것을 모르고 레바를 젖히려다 전혀 움직이지 않으면, 레바가 젖혀지지 않아서 문이 열리지 않는 것으로 착각하여 무리하게 레바를 젖히려는 경우가 많았다.As is well known, the general cylindrical door lock is configured to prevent the external lever from flipping when the locking button is pressed from the inside, so that the door cannot be opened from the outside. Many people thought that the door did not open and tried to squeeze the Leviatic force.

또한 열쇠를 분실하거나 소지하지 않은 상태에서 문을 열고 들어가야 할 때는 점겨진 것을 알면서도 답답한 마음과 혹시나하는 심정에서 레버를 좌, 우로 수차례 젖혀보기도 하므로, 그로인해 내부장치가 마모되어 고장이 나거나 레바가 아래로 쳐지게 되어 미관상 보기흉한 상태가 되기도 하였던 것이다.In addition, when you need to open the door without losing or holding the key, you know that you have stumbled, but you feel the frustration and the feelings of the lever left and right several times. Was struck down and was aesthetically ugly.

이러한 종래 도어록의 잠금구조를 간략하게 살펴보면,Looking briefly at the locking structure of such a conventional door lock,

제5도에 도시된 바와같이 외부레바축(33)에 절개부(34)를 형성하여 내부레바의 잠금보턴을 누르면 잠금축(37)의 잠금부(38)가 절개부(34)에 삽입되어서 외부레바축(33)이 회전하지 못하도록 구성된 것이었다.As shown in FIG. 5, when the cutout portion 34 is formed on the outer lever shaft 33 and the lock button of the inner lever is pressed, the locking portion 38 of the lock shaft 37 is inserted into the cutout 34. The outer lever shaft 33 was configured to prevent rotation.

따라서 무리하게 레바를 젖히려고 하면 절개부(34)와 잠금축(37)의 잠금부(38)가 과도한 힘을 받아 휘어지거나 마모가 발생하므로 고장날 확률이 매우 높았던 것이다.Therefore, if you try to flip the lever forcibly, the incision portion 34 and the locking portion 38 of the lock shaft 37 is bent due to excessive force or wear occurs because the probability of failure was very high.

따라서 본 고안은 전술한 문제점을 개선하기 위하여 안출된 것으로서, 도어록을 잠금 상태에서 외부레바를 젖히면 잠그지 않았을 때와같이 레바가 일정각도 회전하면서도 도어록이 열리지 않도록 하여 무리하게 레바를 젖힘에서 오는 고장을 예방하고 도어록의 수명을 연장시키려는데 목적이 있는 것인바, 이하 첨부된 도면에 의거 그 구성을 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised to improve the above-mentioned problems, and prevents the failure from forcibly flipping the lever by preventing the door lock from opening while the lever is rotated at an angle as if the outer lever is not locked when the door lock is locked. And the purpose is to extend the life of the door lock bar according to the accompanying drawings in detail as follows.

본 고안은 제1도 및 제2도의 도시된 바와같이 실린더형 도어록(1)에 있어서,The present invention is a cylindrical door lock (1) as shown in Figures 1 and 2,

외부레버(2)의 레버축(3)에 걸림절개부(4) 공회전 공간부(5)로 구분된형 절개부(6)를 형성하고 레버축(3)의 내부에 작동관체(7)를 삽입하는데, 작동관체(7)는 선단에 래치작동편(8)(8')을 형성하고 중단부에 두개의 유동공간부(9)(9')를 형성한후, 스프링(10)과 유동판(11)을 삽입하되 유동판(11)에는 길이가 조금긴 걸림편(12)과 길이가 조금짧은 지지편(13)을 형성하여 걸림편(12)은 앞쪽의 유동공간부(9)를 통과하여 레바축(3)의형 절개부(6)에 위치토록 하고 지지편(13)은 뒤쪽의 유동공간부(9')에 위치토록 삽입한 구성이다.The lever shaft 3 of the outer lever 2 is divided into a locking cutout portion 4 and an idling space portion 5. A mold cutout 6 is formed and an operating tube 7 is inserted into the lever shaft 3, which forms a latch operating piece 8, 8 ′ at the tip and a stop portion. After forming two flow spaces 9 and 9 ', the spring 10 and the flow plate 11 are inserted into the flow plate 11, but the locking piece 12 and the length slightly shorter are inserted into the flow plate 11. The support piece 13 is formed so that the locking piece 12 passes through the front flow space 9 so that the lever piece 3 The support piece 13 is positioned so as to be positioned in the mold incision 6 and inserted into the flow space 9 'at the rear.

20 : 키박스20: key box

이러한 구성으로 된 본 고안의 작용 및 효과는 다음과 같다.The operation and effects of the present invention made with such a configuration are as follows.

도어록(1)을 잠그기전의 상태를 우선 살펴보면 문이 닫긴 상태에서 외부레버(2)를 젖히면 레버축(3)이 회전하는데, 이때 작동관체(7)내의 유동판(11)은 스프링(10)의 힘을 받아 전단부에 위치하므로 걸림편(12)이 유동공간부(9)를 통과하여 레버축(3)의 걸림절개부(4)에 위치하기 때문에, 제3도와 같이 레버축(3)과 작동관체(7)가 함께 회전하게 되고 따라서 작동관체(7) 선단부의 래치작동편(8)(8')이 래치작동부(14)를 작동시키면 래치볼트(15)가 후진하여 문을 열수가 있는 것이다.Looking at the state before locking the door lock 1, the lever shaft 3 rotates when the outer lever 2 is flipped while the door is closed. At this time, the flow plate 11 in the working tube 7 is connected to the spring 10. Since the locking piece 12 is located in the front end portion under the force, the locking piece 12 passes through the flow space 9 and is positioned in the locking cutout portion 4 of the lever shaft 3, and thus the lever shaft 3 and When the operating body 7 rotates together, and the latching operation piece 8, 8 ′ at the tip of the operating body 7 operates the latch operating part 14, the latch bolt 15 moves backward to open the door. It is.

도어록(1)을 접근 상태의 작용을 보면, 내부레버(2a)에 돌출된 잠금보턴(16)을 누르면 잠금축(17)이 전진하여 끝단의 누름판(18)이 유동판(11)을 밀어넣어 제4도와 같이 유동판(11)의 걸림편(12)이 공회전 공간부(5)로 위치하게 되는데, 이때 외부레버(2)를 젖히면 회전은 하되 레버축(3)이 유동판(11)의 걸림편(12)을 걸고 돌아가지 못하므로 작동관체(7)가 회전하지 않으며, 따라서 래치볼트(15)를 작동시킬 수 없어서 문을 열수가 없게 되는 것이다.When the door lock 1 is operated in an approaching state, when the lock button 16 protruding from the inner lever 2a is pressed, the lock shaft 17 moves forward, and the pressing plate 18 at the end pushes the fluid plate 11. As shown in FIG. 4, the engaging piece 12 of the flow plate 11 is positioned as the idling space 5. At this time, when the outer lever 2 is folded, the lever shaft 3 rotates while the lever shaft 3 of the flow plate 11 is rotated. Since the operating piece 7 does not rotate because the locking piece 12 is not turned, the door cannot be opened because the latch bolt 15 cannot be operated.

물론, 이때 내부레버(2a)를 젖히면 내부레버축(3a) 선단의 래치작동편(19)에 의해 래치볼트(15)를 작동시키면서 문이 열림과 동시에 잠금축(17)이 후진하는 것이며, 외부에서 열쇠를 사용하면 키박스(20)가 직접 작동관체(7)를 회전시켜 문을 열수가 있는 것이다.Of course, at this time, when the inner lever 2a is flipped, the lock shaft 17 is reversed at the same time as the door is opened while the latch bolt 15 is operated by the latch operating piece 19 at the tip of the inner lever shaft 3a. If you use the key in the key box 20 can be directly opened the door by rotating the operating body (7).

한편 전기한 본 고안의 요부구성은 레버형 도어록을 기준으로 설명하였으나 레버형 도오록 뿐만아니라 노브(KNOB)형 도어록등 기타 여러가지의 실린더형 도어록에 그대로 적용시킬 수 있다.Meanwhile, the main configuration of the present invention described above is based on a lever-type door lock, but it can be applied to various cylinder-type door locks as well as a lever-type door lock as well as a knob (KNOB) type door lock.

이상과 같이 구성되고 작용되는 본 고안은 잠금축(17)에 의해 유동판(11)이 레버축(3)의형 절개부(6)내를 이동하게 하는 간단한 구성으로 문이잠겨져 있다는 것을 쉽게 인실할 수 있을 뿐아니라 레바를 회전시키더라도 문이 열리지 않게 되므로 과도한 레버작동으로 인한 파손 및 고장을 미연에 예방할 수 있고 도어록의 수명을 연장시킬 수 있는 등 매우 유용한 고안인 것이다.The present invention is constructed and acted as described above is the liquid plate 11 by the locking shaft 17 of the lever shaft (3) The simple configuration to move the inside of the incision 6 can not only easily realize that the door is locked, but also the door does not open even if the lever is rotated, thereby preventing damage and failure due to excessive lever operation. It is a very useful design such as to extend the life of the door lock.
