이하, 본 발명의 바람직한 실시 예를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1내지는 도 3에서 도시한 바와 같이,1 to 3, as shown in FIG.
도어의 내측패널(134)과 외측패널(136) 사이에는 케이싱(110)이 설치되어 있고, 이 케이싱(110)의 일측에 뚫려진 출입공(112)에는 잠금봉(114)이 삽입되어 케이싱(110)의 내부에서 가로방향으로 장착되어 있다.A casing 110 is installed between the inner panel 134 and the outer panel 136 of the door, and the lock rod 114 is inserted into the access hole 112 drilled on one side of the casing 110 to insert the casing ( 110 is mounted in the horizontal direction.
상기 잠금봉(114)에는 걸림편(117)에 의하여 지지되는 스프링(130a)이 장착되어 잠금봉(114)이 케이싱(110) 내부에서 탄력적으로 설치되며, 잠금봉(114)의 후방에는 스토퍼(118)들이 형성되어 일정한 범위 사이에서 잠금봉(114)이 이동된다.The locking rod 114 has a spring 130a supported by the locking piece 117 so that the locking rod 114 is elastically installed in the casing 110, and a stopper at the rear of the locking rod 114. 118 are formed to move the lock rod 114 between certain ranges.
상기 잠금봉(114)의 일부는 래크기어(116)로 형성되어 있고, 이 래크기어(116)에는 정,역회전모터(122)와 일체로 결합된 감속기(122)의 피니언기어(120)가 치합되어 피니언기어(120)의 회전시 이에 치함된 래크기어(116)의 이동에 의하여 잠금봉(114)이 이동되면서 문틀에 장착된 고정용케이싱(102)의 잠금공(108)로 출입되어 잠금장치(100)가 괘,해정되는 구성으로 되어 있다.A part of the lock rod 114 is formed of a rack gear 116, the pinion gear 120 of the reducer 122 is integrally coupled with the forward and reverse rotation motor 122, the rack gear 116 ) Is engaged to the locking hole 108 of the fixing casing 102 mounted on the door frame while the lock rod 114 is moved by the movement of the rack gear 116 driven by the pinion gear 120 is rotated. The entrance and exit of the locking device 100 is configured to be locked.
상기한 정,역회전모터(122)는 제어부(104)에 의하여 작동되며, 이 제어부(104)는 리모콘(132)의 신호를 수신하여 정,역회전모터(122)에 신호를 인가하는 시스템으로 되어 있다.The forward and reverse rotation motor 122 is operated by the control unit 104, the control unit 104 is a system for receiving a signal from the remote control 132 to apply a signal to the forward and reverse rotation motor 122 It is.
이와 같이 제어부(104)가 리모콘(132)의 신호를 수신하여 모터를 구동시키는 기술구성은 이미 알려진 공지의 기술구성이므로 상세한 설명은 생략하였다.As described above, since the control unit 104 receives a signal from the remote controller 132 and drives the motor, a detailed description thereof is omitted since it is a known technology configuration.
전술한 구성으로 이루어진 본 발명은, 사용자가 문을 괘정시켜야 하는 경우에는 먼저 리모콘(132)의 잠금 버튼을 눌러 잠금상태를 지시하면 리모콘(132)에 의해 송신되는 신호가 제어부(104)에 의해 수신되고 이 신호는 정,역회전모터(124)를 좌측방향으로 회동시키게 된다.According to the present invention having the above-described configuration, when the user needs to lock the door, the controller 104 receives a signal transmitted by the remote controller 132 when the user first presses the lock button of the remote controller 132 to indicate the locked state. This signal causes the forward and reverse rotation motor 124 to rotate leftward.
따라서, 정,역회전모터(122)의 회전력이 감속기(122)에 의하여 감속되어 피니언기어(120)를 좌측방향으로 회전시키게 되고, 이에 치합된 래크기어(116)를 좌측으로 이동시킴에 따라 케이싱(110)의 출입공(112)에 삽입되어 있는 잠금봉(114)이 좌측으로 이동되어 고정용케이싱(102)의 잠금공(108)에 삽입되어 도어가 괘정되는 것이다.Therefore, the rotational force of the forward and reverse rotation motor 122 is decelerated by the reducer 122 to rotate the pinion gear 120 in the left direction, and moves the rack gear 116 engaged thereto to the left. The lock rod 114 inserted into the access hole 112 of the casing 110 is moved to the left side and inserted into the lock hole 108 of the fixing casing 102 so that the door is determined.
이와는 반대로 문을 해정시키는 경우에는 리모콘(132)의 열림 버튼을 눌러 정,역회전모터(124)를 우측방향으로 회동시킴에 따라, 피니언기어(120)가 우측으로 회전되어 이에 치합된 래크기어(116)와 잠금봉(114)이 우측으로 이동됨에 따라 고정용케이싱(102)의 잠금공(108)에 삽입된 잠금봉(114)이 이탈되어 도어가 해정되는 것이다.On the contrary, in the case of releasing the door, as the forward and reverse rotation motor 124 is rotated to the right by pressing the open button of the remote controller 132, the pinion gear 120 is rotated to the right and engaged with the rack gear. As the lock 116 and the lock rod 114 are moved to the right side, the lock rod 114 inserted into the lock hole 108 of the fixing casing 102 is separated and the door is released.
물론, 상기 잠금봉(114)은 그 후방에 구비된 스토퍼(118)에 의하여 소정의 범위 내에서만 좌,우측으로 이동되므로 케이싱(110)의 출입공(112)에서 이탈이 방지되는 것이다.Of course, since the locking rod 114 is moved to the left and right side only within a predetermined range by the stopper 118 provided at the rear thereof, the lock rod 114 is prevented from being separated from the access hole 112 of the casing 110.
이와 같은 본 고안은 리모콘(132)의 작동에 의하여 잠금봉(114)이 좌,우측으로 이동되면서 도어를 괘,해정시키므로 도어의 전면에 장착되는 별도의 키 버튼이나 열쇠 구멍 등의 사용이 불필요하므로 잠금장치(100)가 단순화되어 제작원가의 절감 및 생산성을 향상시키고 도어의 외관을 미려하게 유지할 수 있는 것이므로 대외 경쟁력이 있는 고부가가치의 잠금장치(100)를 얻을 수 있는 이점이 있는 것이다.This invention devises the locking rod 114 to the left and right side by the operation of the remote control 132 to lock the door, so the use of a separate key button or key hole mounted on the front of the door is unnecessary Since the locking device 100 is simplified to improve manufacturing cost and improve productivity, and maintain the appearance of the door beautifully, there is an advantage of obtaining a high value-added locking device 100 having a competitive edge.
또한, 열쇠의 전문가라 하더라도 도어의 외부에 노출되는 것이 전혀 없는 것이므로 잠금장치(100)를 해정시키거나 파손되는 폐단이 방지되어 도난으로부터 사용자를 안전하게 보호할 수 있는 이점이 있다.In addition, even if the expert of the key is not exposed to the outside of the door at all, there is an advantage that can prevent the closed end to release or break the lock device 100 to protect the user from theft.
한편, 상기 정,역회전모터(122)는 케이싱(110)의 내부에서 축(125) 결합되어 스프링(130b)으로 지지되고, 케이싱(110)의 외측으로 돌출된 레버(126)에는 캠(128)이 장착되어 정,역회전모터(122)의 하부 일측을 지지토록 구성되어 있다.On the other hand, the forward and reverse rotation motor 122 is coupled to the shaft 125 inside the casing 110 is supported by a spring 130b, the cam 128 in the lever 126 protruding out of the casing 110 ) Is mounted to support the lower one side of the forward and reverse rotation motor 122.
따라서, 정전(停電)시 정,역회전모터(122)를 구동시킬 수 없는 경우가 발생되면 상기 레버(126)를 상측으로 회동시켜 캠(128)이 정,역회전모터(122)의 좌측 하부면을 상측으로 밀게되면 우측에 위치된 감속기(122)의 피니언기어(120)는 하측으로 회동되면서 도 4에서 도시한 바와 같이 피니언기어(120)가 래크기어(116)에서 이탈되어 잠금봉(114)이 자유로운 상태를 유지하게 되고 동시에 스프링(130a)의 탄발력에 의하여 잠금봉(114)이 우측으로 이동되어 잠금상태를 해정시킬 수 있도록 되어 있다.Therefore, if a case in which the forward and reverse rotation motors 122 cannot be driven at the time of power failure occurs, the lever 126 is rotated upward and the cam 128 is lower left of the forward and reverse rotation motors 122. When the surface is pushed upward, the pinion gear 120 of the reducer 122 located on the right side is rotated downward and the pinion gear 120 is separated from the rack gear 116 as shown in FIG. 114 is kept free and at the same time the locking rod 114 is moved to the right by the spring force of the spring 130a to release the locked state.
물론, 이러한 장치는 정전과 같은 비상시를 대비하여 설치된 것이나, 고정용케이싱(102) 내부에 구비되어 제어부(104)로 전원을 공급하는 DC충전기(106)에 의하여 정전이 되더라도 소정의 기간 내에서는 충전된 전원이 공급되므로 잠금장치(100)를 리모콘(132)로 작동시킬 수 있도록 되어 있다.Of course, such a device is installed in case of an emergency such as a power failure, but is charged within a predetermined period even if a power failure is provided by the DC charger 106 provided inside the fixing casing 102 and supplying power to the controller 104. Since the supplied power is supplied, the locking device 100 can be operated by the remote controller 132.
이상에서 상술한 바와 같은 본 발명은, 도어의 내측에 장착되는 케이싱(110)의 내부에는 그 일부가 래크기어(116)로 형성된 잠금봉(114)이 횡으로 장착되고 정,역회전모터(122)와 일체로 결합된 감속기(122)의 피니언기어(120)가 래크기어(116)에 치합되어 리모콘(132)과 제어부(104)의 신호로 작동되는 정,역회전모터(122)에 의하여 잠금봉(114)이 문틀에 장착된 고정용케이싱(102)의 잠금공(108)을 괘,해정시키는 도어의 잠금장치를 구성토록 함으로써, 상기 리모콘(132)의 작동에 의하여 잠금봉(114)이 좌,우측으로 이동되면서 도어를 괘,해정시키므로 도어의 전면에 장착되는 별도의 키 버튼이나 열쇠 구멍 등의 사용이 불필요하므로 잠금장치(100)가 단순화되어 제작원가의 절감 및 생산성을 향상시키고 도어의 외관을 미려하게 유지할 수 있는 동시에 열쇠의 전문가라 하더라도 도어의 외부에 노출되는 것이 전혀 없는 것이므로 잠금장치(100)를 해정시키거나 파손되는 폐단이 방지되어 도난으로부터 사용자를 안전하게 보호할 수 있는 등의 이점이 있다.According to the present invention as described above, the inside of the casing 110 mounted on the inside of the door, the lock rod 114 formed of a rack gear 116 a portion thereof is mounted horizontally and the forward, reverse rotation motor ( The pinion gear 120 of the reducer 122 integrally coupled with the gear 122 is engaged with the rack gear 116 to the forward and reverse rotation motors 122 operated by signals of the remote controller 132 and the controller 104. By the locking rod 114 to configure the locking device of the door for locking and releasing the locking hole 108 of the fixing casing 102 mounted on the door frame, the locking rod 114 by the operation of the remote control 132. Since the door moves to the left and right side, it locks and releases the door, so the use of a separate key button or key hole installed on the front of the door is unnecessary, so that the locking device 100 is simplified to reduce production cost and improve productivity. I can keep the appearance of the door beautifully and am the expert of the key Because even if it is not at all exposed to the outside of the door is the closed end to unlock the locking device 100, or damage is prevented there is an advantage such that it is safe to protect the user against theft.
