이를 위해 본 발명은, 도 1 내지 도 4을 참조하면, 크게 결합부(100)와 잠금부(200)를 포함하여 구성한다. To this end, the present invention, referring to FIGS. 1 to 4, is configured to include a coupling part 100 and a locking part 200.
먼저, 본 발명의 결합부(100)는, 도어손잡이(20)가 설치된 도어(10)의 면 상에 설치하는데, 도어손잡이(20)의 설치부위에서 도어손잡이와 폭 방향으로 인접하면서 이미 설정된 크기와 두께의 판 형상을 가진다. 다시 말해, 도어손잡이의 전후방향 후방 부위의 도어에 설치가 이루어진다. First, the coupling part 100 of the present invention is installed on the surface of the door 10 where the door handle 20 is installed, and is adjacent to the door handle in the width direction at the installation site of the door handle 20 and has a preset size. It has a plate shape of and thickness. In other words, it is installed on the door at the front and rear rear portion of the door handle.
이때, 바람직하게 결합부(100)는, 금속 또는 강성의 플라스틱을 포함하는 합성수지 재질로 이루어지며, 접착 또는 볼트나 피스 등 결합부재를 통한 체결의 방식으로 도어(10)에 탈착가능하게 결합한다.At this time, the coupling part 100 is preferably made of a synthetic resin material including metal or rigid plastic, and is detachably coupled to the door 10 by bonding or fastening through a coupling member such as a bolt or piece.
이어서, 본 발명의 잠금부(200)는, 상술의 결합부(100)와 동일 또는 유사한 금속 또는 강성의 플라스틱을 포함하는 합성수지 재질로 이루어지며, 마주하는 한 쌍으로 이루어져 도어손잡이(20)를 감싸는 형상을 이루며 상술의 결합부(100)에 결합한다. Subsequently, the locking part 200 of the present invention is made of a synthetic resin material containing the same or similar metal or rigid plastic as the above-described coupling part 100, and consists of a pair facing the door handle 20 surrounding the door handle 20. It forms a shape and is coupled to the coupling part 100 described above.
이때, 잠금부(200)는, 한 쌍 중 선택된 어느 하나 또는 한 쌍 모두가 후방의 축을 중심으로 젖혀지도록 결합부(100)에 전후방향으로 회동 가능하게 결합되어 도어손잡이(20)의 상측 또는 하측으로의 회동을 선택적으로 단속할 수 있도록 기능한다.At this time, the locking part 200 is rotatably coupled to the coupling part 100 in the forward and backward directions so that any one or all of the selected one pair of the pair is bent around the rear axis, so that the upper or lower side of the door handle 20 It functions to selectively control the rotation to
본원발명의 일 실시예에 따른, 도어손잡이 안전 잠금장치의 구체적인 구성은 하기와 같다. According to an embodiment of the present invention, a specific configuration of the door handle safety locking device is as follows.
일 실시예로, 잠금부(200)는, 도 1 내지 도 4와 같이, 결합부(100)로부터 전방으로 돌출되며 전후방향에 따른 종단면이 'ㄷ'자와 유사한 형상으로 이루어지고, 상측에 위치하여 제1회동축(211)을 통해 결합부(100)에 전후방향으로 회동 가능한 결합을 이루는 회동부재(210)와, 하측에 위치하여 후방의 단면이 상기 회동부재(210)의 후방 단면과 면접촉을 이루면서 상기 결합부(100)에 결합을 이루는 지지부재(220)를 포함하여 구성한다. In one embodiment, the locking part 200 protrudes forward from the coupling part 100, as shown in FIGS. 1 to 4, and has a longitudinal cross section along the front-back direction in a shape similar to a 'c' character, and is located on the upper side. The rotational member 210 forming a rotatable coupling in the forward and backward directions to the coupling part 100 through the first rotational shaft 211, and the rear end face of the rotational member 210 is located on the lower side and the surface It is configured to include a support member 220 forming a coupling to the coupling portion 100 while making contact.
도면에서는 회동부재(210)가 지지부재(220)의 상측에 위치하는 것으로 도시하였으나, 이에 한정하는 것은 아니며 회동부재(210)와 지지부재(220)는 필요에 따라 회동부재(210)가 하측에 지지부재(220)가 상측에 위치하도록 그 위치가 서로 바뀌어 위치할 수 있음은 물론이다. In the drawing, the pivoting member 210 is shown as being located on the upper side of the support member 220, but is not limited thereto, and the pivoting member 210 and the support member 220, if necessary, the pivoting member 210 is positioned on the lower side. Of course, the positions of the support members 220 may be positioned interchangeably so as to be located on the upper side.
다만, 본원발명에서 바람직한 일 실시예로는, 도 1 내지 도 4에서 도시한 바와 같이 회동부재(210)가 지지부재(220)의 상측에 위치하는 것이 바람직하다. 다시 말해, 도어손잡이(20)의 상부에 회동부재(210)가 위치하고 하부에 지지부재(220)가 위치하여 회동부재(210)와 지지부재(220)가 도어손잡이(20)를 상하에서 감싸도록 설치함이 바람직하다.However, as a preferred embodiment of the present invention, it is preferable that the rotation member 210 is positioned above the support member 220 as shown in FIGS. 1 to 4 . In other words, the rotation member 210 is positioned above the door handle 20 and the support member 220 is located below the door handle 20 so that the rotation member 210 and the support member 220 surround the door handle 20 from above and below. It is preferable to install
이는 키가 작은 유아가 도어를 개폐하는 도어손잡이(20)에 통상 매달려 아래로 잡아당겨 도어를 여는 경우가 많음에 따라 지지부재(220)를 도어손잡이(20) 하부에 위치시켜 유아가 도어손잡이(20)에 매달려도 지지부재(220)가 유아가 가하는 하중을 견딜 수 있게 하고 도어손잡이(20)가 지지부재(220)에 걸려 도어(10) 열림을 단속하게 한다. This is because there are many cases in which a short infant usually hangs on the door handle 20 that opens and closes the door and pulls down to open the door. 20), the support member 220 can withstand the load applied by the infant, and the door handle 20 is caught on the support member 220 to control the opening of the door 10.
이렇게 구성한 본 발명의 잠금부(200)에서, 도 3 및 도 4와 같이, 지지부재(220)는 회동부재(210)의 후방 단면과 면접촉을 이루는 내측 위치에 걸림턱(221)을 형성한다. In the locking part 200 of the present invention configured as described above, as shown in FIGS. 3 and 4, the supporting member 220 forms a locking jaw 221 at an inner position making surface contact with the rear end surface of the pivoting member 210. .
그리고, 상기 회동부재(210)에는 상기 지지부재(220)의 후방 단면과 인접한 내측 위치의 후방 단부에 제2회동축(213)을 통한 레버수단(212)이 결합될 수 있다.In addition, a lever means 212 may be coupled to the rear end of the support member 220 at an inner position adjacent to the rear end of the pivot member 210 through a second pivot shaft 213.
이때, 상기 레버수단(212)의 일측(도시에서 상측) 단부는 상기 회동부재(210) 일측(도시에서 상부) 외측으로 이미 설정된 길이만큼 돌출을 이루면서 타측(도시에서 하측) 단부에는 후크수단(214)을 구비할 수 있다.At this time, one side (upper side in the illustration) end of the lever means 212 protrudes to the outside of one side (upper side in the illustration) of the pivot member 210 by a previously set length, while the other (lower side in the illustration) end has a hook means 214 ) can be provided.
이러한 후크수단(214)이 지지부재(220)의 걸림턱(221)에 걸린 상태에서 도어손잡이(20)의 회동을 단속할 수 있게 된다.In a state where the hook means 214 is caught on the locking jaw 221 of the support member 220, the rotation of the door handle 20 can be controlled.
더하여, 상기 레버수단(212)은 상기 제2회동축(213)에서 전방으로 돌출된 탄성부재(215)를 구비하여 상기 탄성부재(215)가 상기 회동부재(210)의 후방 단부와 면접촉을 이룸을 통해 상기 회동부재(210)와 연결될 수 있다.In addition, the lever means 212 has an elastic member 215 protruding forward from the second rotation shaft 213 so that the elastic member 215 makes surface contact with the rear end of the rotation member 210. It can be connected to the rotation member 210 through this room.
이를 통해, 사용자에 의한 레버수단(212)의 가압에 따라 회동부재(210)가 후방으로의 회동을 이룬 상태에서, 상술한 레버수단(212)의 가압을 해제함과 동시에 레버수단(212)이 탄성적으로 회동하여 후크수단(214)이 상기 걸림턱(221)에 걸리게 되면서 회동부재(210)는 전방으로 회동하여 도어손잡이(20)의 잠금상태로 복귀할 수 있게 된다.Through this, in a state in which the pivoting member 210 rotates backward according to the pressurization of the lever means 212 by the user, the above-described pressurization of the lever means 212 is released, and at the same time, the lever means 212 As the hook means 214 is elastically rotated and caught on the locking jaw 221, the rotation member 210 rotates forward to return to the locked state of the door handle 20.
즉, 사용자가 도어(10)를 개방시키고자 도어손잡이(20)를 회동시키려할 때, 사용자는 상기 레버수단(212)의 회동부재(210) 상부 외측으로 돌출을 이룬 부위를 가압하게 되고 이와 동시에 상기 후크수단(214)이 상기 걸림턱(221)에 걸려진 상태가 해제되면서 회동부재(210)가 후방으로 회동하여 도어손잡이(20)를 길이방향 상측으로 회동시킬 수 있는 상태에 놓이게 된다.That is, when the user tries to rotate the door handle 20 to open the door 10, the user presses the portion of the lever means 212 that protrudes outward from the top of the pivot member 210, and at the same time As the state in which the hook means 214 is hooked to the locking jaw 221 is released, the rotation member 210 rotates rearward to put the door handle 20 in a state in which it can rotate upward in the longitudinal direction.
그리고, 상기 레버수단(212)의 회동부재(210) 상부 외측으로 돌출을 이룬 부위를 가압하는 것을 해제함과 동시에 상술한 바와 같이 레버수단(212)의 회동으로 인해, 상기 회동부재(210)가 탄성적으로 전방 회동을 이루어 도어손잡이(20)의 잠금상태로 복귀할 수 있는 것이다.In addition, the pressing of the portion protruding outward from the upper part of the pivot member 210 of the lever means 212 is released and, as described above, due to the rotation of the lever means 212, the pivot member 210 It is possible to return to the locked state of the door handle 20 by elastically rotating forward.
예컨대, 상기 탄성부재(215)는 통상의 판스프링으로 이루어질 수 있고, 이에 따라 상기 레버수단(212)의 회동부재(210) 상부 외측으로 돌출을 이룬 부위의 가압과 그 가압의 해제를 통해, 상기 탄성부재(215)가 상기 회동부재(210)의 후방 단부와 면접촉을 이룬 상태에서 탄성적인 휨변형을 구현하게 됨으로써, 상기 회동부재(210)가 탄성적으로 회동하여 도어손잡이(20) 회동의 잠금과 그 해제 상태를 편리하고 간단하게 이룰 수 있게 되는 것이다.For example, the elastic member 215 may be formed of a normal leaf spring, and accordingly, through the pressing of the portion protruding outwardly of the pivot member 210 of the lever means 212 and the release of the pressing, Since the elastic member 215 realizes elastic bending deformation in a state in which it makes surface contact with the rear end of the pivoting member 210, the pivoting member 210 elastically pivots to improve the rotation of the door handle 20. Locking and unlocking can be done conveniently and simply.
필요에 따라 이러한 탄성부재(215)는 토션스프링과 같이 탄성을 부여할 수 있다면 다른 구성요소를 적용할 수 있음은 물론이다.Of course, other components can be applied to the elastic member 215 as needed as long as it can impart elasticity such as a torsion spring.
한편, 이러한 본 발명의 회동부재(210) 및 지지부재(220)는 각각 폭(좌우) 방향으로 분리 가능한 한 쌍이 결합을 이루도록 구성될 수 있는데, 이때에는 한 쌍을 이루는 것들 중 어느 하나의 결합부위 둘레부를 따라 다수의 결합돌기(B)를 돌출 구비하고, 나머지 하나의 결합부위 둘레부를 따라서는 다수의 상기 결합돌기(B)에 대응하는 결합홈(미도시)을 형성한 구성으로 이루어져 결합될 수 있다.On the other hand, the rotation member 210 and the support member 220 of the present invention may be configured so that a pair that is detachable in the width (left and right) direction is coupled. In this case, any one of the pair of coupling parts A plurality of coupling protrusions (B) are protruded along the circumference, and coupling grooves (not shown) corresponding to the plurality of coupling protrusions (B) are formed along the circumference of the other coupling portion. there is.
이와는 다르게 상기 회동부재(210) 및 지지부재(220) 각각이 폭 방향으로 한 쌍을 이루되, 이 한 쌍의 회동부재(210) 및 지지부재(220)들은 각각 접착을 통한 결합을 이룰 수 있고, 또한 별도로 구비된 볼트 또는 피스 등의 체결수단을 이용한 결합을 이룰 수 있음 또한 가능하다 할 것이다.Unlike this, each of the pivot member 210 and the support member 220 forms a pair in the width direction, and the pair of pivot member 210 and support member 220 can be bonded through adhesion, respectively, , It will also be possible to achieve coupling using fastening means such as separately provided bolts or pieces.
이때, 한 쌍으로 이루어진 상기 회동부재(210) 중 어느 하나에 상기 레버수단(212) 및 제2회동축(213)이 구비되며, 한 쌍으로 이루어진 상기 지지부재(220) 중 상기 레버수단(212) 및 제2회동축(213)을 구비한 상기 회동부재(210)와 폭 방향으로 동일한 위치에 배치된 지지부재(220)에 상기 걸림턱(221)이 형성될 수 있다.At this time, the lever means 212 and the second pivot shaft 213 are provided on any one of the pair of pivot members 210, and the lever means 212 of the pair of support members 220 ) and the second rotational shaft 213 and the rotation member 210 and the support member 220 disposed at the same position in the width direction can be formed on the projection 221.
나아가, 상기 회동부재(210) 및 지지부재(220) 각각은, 상술한 바와 같은 폭 방향의 한 쌍으로 구비되어 결합을 이루는 구성이 아닌 통상의 사출성형 등의 방법으로 일체로 제작될 수 있는 것도 가능함은 물론이다.Furthermore, each of the rotation member 210 and the support member 220 is provided as a pair in the width direction as described above and can be integrally manufactured by a method such as a normal injection molding rather than a configuration forming a coupling. Of course it is possible.
상술한 바와 같이, 본 발명은 상기 잠금부(200)를 이루는 회동부재(210)의 회동과, 회동을 이루지 않은 채 걸림턱(221)의 구성을 통해 도어손잡이(20)의 잠금상태를 견고히 지지하는 지지부재(220)를 통한 안전성의 확보를 구현할 수 있도록 하였다.As described above, the present invention firmly supports the locked state of the door handle 20 through the rotation of the rotation member 210 constituting the locking part 200 and the configuration of the locking jaw 221 without rotation. To ensure safety through the support member 220 can be implemented.
하지만, 이는 도어손잡이(20)의 회동방향이 상측 방향일 경우에 한정적으로 적용할 수 있는 것이고, 도어손잡이(20)가 상측 또는 하측 양방향으로 회동될 수 있는 것에 대응하기 위해, 상기 회동부재(210) 및 지지부재(220)의 구성 위치를 전환하여 적용할 수 있음은 물론이다.However, this is limitedly applicable when the rotation direction of the door handle 20 is upward, and in order to correspond to the fact that the door handle 20 can be rotated in both directions upward or downward, the rotation member 210 ) and the configuration position of the support member 220 can be switched and applied.
또한 잠금부(200)는 필요에 따라 지지부재(220)의 구성이 없이 상측과 하측에 둘다 회동부재(210)로 구성할 수 있으며, 이러한 구성이 본원발명의 기술적 사상을 벗어나는 것은 아니다. In addition, the locking unit 200 may be configured with the pivot member 210 on both the upper and lower sides without the support member 220 as needed, and this configuration does not deviate from the technical spirit of the present invention.
다시 말해, 상술의 지지부재(220) 또한 상술의 회동부재(210)와 동일 또는 유사하게 상기 레버수단(212) 등의 구성을 구비토록 하여 본 발명에 따른 도어손잡이 안전 잠금장치의 범용적인 사용이 가능할 수 있도록 함이 바람직하다.In other words, the above-mentioned support member 220 also has the same or similar structure as the above-mentioned pivot member 210, such as the lever means 212, so that the door handle safety locking device according to the present invention can be used universally. It is desirable to make it possible.
도 5와 도 6을 참조하여, 본 발명의 다른 실시예에 따른 구성을 살펴보면 하기와 같다.Referring to Figures 5 and 6, looking at the configuration according to another embodiment of the present invention is as follows.
본 발명의 다른 실시예에 따른 도어손잡이 안전 잠금장치는, 결합부(100)와, 회동부재(210) 및 지지부재(220)로 이루어진 잠금부(200)를 구비하고 있음은 상술한 바와 같다.As described above, the door handle safety locking device according to another embodiment of the present invention includes a locking part 200 composed of a coupling part 100, a pivoting member 210, and a supporting member 220.
다만, 회동부재(210)에서 상기 레버수단(212)은 회동부재(210)의 상부 외측으로 이미 설정된 길이만큼 돌출을 이룬 부위에 탄성부재(215)를 구비하여 상기 탄성부재(215)가 상기 회동부재(210)의 후방 상면과 면접촉을 이룸을 통한 상기 회동부재(210)와 연결될 수 있도록 한 것에 특징이 있다.However, in the pivoting member 210, the lever means 212 is provided with an elastic member 215 at a portion protruding outside the upper part of the pivoting member 210 by a predetermined length so that the elastic member 215 rotates. It is characterized in that it can be connected to the pivot member 210 through surface contact with the rear upper surface of the member 210.
이를 통해, 상기 레버수단(212)의 회동부재(210) 상부 외측으로 돌출을 이룬 부위를 가압함과 동시에 상기 후크수단(214)이 상기 걸림턱(221)에 걸려진 상태가 해제되어 상기 회동부재(210)가 후방으로 회동할 수 있게 된다.Through this, a portion of the lever means 212 protruding outward from the top of the pivot member 210 is pressed, and at the same time, the state in which the hook means 214 is caught on the locking jaw 221 is released, and the pivot member 214 is released. (210) is able to rotate backwards.
예컨대, 상기 탄성부재(215)는 상술한 본 발명의 일 실시예와 같이, 통상의 판스프링으로 이루어질 수 있다.For example, the elastic member 215 may be formed of a normal leaf spring, as in one embodiment of the present invention described above.
