Description

지게차의 캐빈에 드릴 작업 없이 장착되는 도어개폐장치{A door opening and closing device mounted on a cabin of a forklift without drilling}A door opening and closing device mounted on a cabin of a forklift without drilling}

본 발명은 지게차의 캐빈의 차체 틀을 구성하는 파이프에 드릴작업을 하지 않은 상태에서 도어의 개폐를 단속하는 락장치를 추가적인 드릴작업을 하지 않은 상태에서 장착토록 한 지게차 캐빈용 도어개폐장치에 관한 것이다.The present invention relates to a door opening and closing device for a forklift cabin in which a lock device that regulates the opening and closing of a door in a state in which a pipe constituting a body frame of a forklift cabin is not drilled is mounted without additional drilling work. .

일반적으로 지게차에는 구동에 필요한 전기배선이 외부로 노출되지 않도록 하면서 운행이나 작업 중에 전복사고나 충돌에 의해 충격이 가해졌을 때 탑승공간에 탑승한 운전자의 안전도를 위하여 캐빈틀이 일체로 구비된 완성차로 제조되는 것이다.In general, a forklift is a complete vehicle equipped with a cabin for the safety of the driver in the boarding space when an impact is applied by a rollover accident or collision during operation or work while preventing the electric wiring required for driving from being exposed to the outside. It is manufactured.

또한, 지게차가 완성된 후에는 캐빈틀의 파이프 두께나 휘는 각도 등의 각종 안전시험이 이루어지게 되고, 이러한 안전시험을 통과하여 안전승인을 받은 상태에서만 출고되어 판매가 이루어지게 되는 것이다.In addition, after the forklift is completed, various safety tests, such as the thickness of the pipe of the cabin and the bending angle, are conducted, and are sold only after passing these safety tests and receiving safety approval.

그러나 대부분 지게차를 구매한 구매자들은 지게차 캐빈을 전문으로 제작하는 업체를 통하여 실내 또는 실외의 작업환경에 따라서 캐빈틀에 창호와 도어를 장착하게 된다.However, most of the forklift buyers install windows and doors on the cabin according to the indoor or outdoor work environment through a company that specializes in forklift cabins.

즉, 실외에서 작업하는 지게차는 비 또는 눈이 내리는 추운 겨울 또는 더운 여름에 탑승자의 작업효율을 높이기 위하여 전,후면으로 프레임에 의한 창호가 설치되고, 좌,우 양측면에는 락장치에 의해 개폐가 이루어지는 도어가 장착되는 것이다. That is, a forklift that works outdoors has windows and doors installed on the front and rear sides by a frame to increase the work efficiency of the occupants in the cold winter or hot summer when rain or snow falls, and the left and right sides are opened and closed by locking devices. The door is mounted.

따라서 이러한 창호프레임이나 도어를 장착하기 위해서 종래에는 드릴에 의한 홀 가공이나 용접으로 장착을 하였으나, 이럴 경우에 구동을 위해 배선된 전기배선이 드릴작업에 의해 훼손되어 화재나 오작동의 원인이 되었고, 홀 가공 또는 용접에 따라서 파이프의 금속성질이 변형이 발생되면서 이러한 구조변경된 캐빈틀의 안전시험을 위한 검사과정을 다시 받아야 하는 문제가 있었고, 특히 시간과 비용발생이 추가로 발생되면서 구매자에게 시간의 손해와 경제적인 부담이 동시에 가중되는 문제가 있었다.Therefore, in order to mount such a window frame or door, conventionally, hole processing or welding was performed with a drill, but in this case, the electric wiring wired for driving was damaged by the drilling operation, causing fire or malfunction. As the metal properties of the pipe are deformed according to processing or welding, there is a problem that the inspection process for the safety test of the cabin that has been restructured needs to be retaken.In particular, time and cost incurred additionally, causing loss of time and There was a problem that the economic burden was increased at the same time.

특히 해외로 수출되는 지게차의 경우에는 안전시험이 매우 까다로울 뿐만 아니라, 안전시험을 다시 받기 위한 시간과 고비용으로 인하여 더 큰 경제적 손실을 발생시키는 문제가 있었다.In particular, in the case of forklifts exported overseas, the safety test is very difficult, and there is a problem of causing a greater economic loss due to the time and high cost to retake the safety test.

따라서 본 발명의 출원인이 특허출원하여 등록받은 특허등록 제10-1879157호에 따르면, 캐빈틀의 파이프에 천공을 위한 드릴작업이나 용접을 하지 않고, 다양한 구조의 브라켓에 의하여 장착토록 한 것이 제안되었으나, 도어의 개폐를 단속하는 락장치를 장착하기 위해서는 최소의 드릴구멍을 천공해야만 장착이 가능하기 때문에 이러한 개선작업이 필요하였다.Therefore, according to Patent Registration No. 10-1879157, which was registered by the applicant of the present invention, it has been proposed that the pipe of the cabin is not drilled or welded for drilling, but is mounted by brackets of various structures. In order to mount the lock device that regulates the opening and closing of the door, such an improvement work was necessary because the installation is possible only by drilling a minimum drill hole.

따라서 본 발명은 도어의 개폐를 위한 도어락 장치를 캐빈틀에 홀 천공이나 용접작업없이 도어에 직접 장착하여 간단하게 장착하면서 도어의 락이 캐빈틀의 파이프에 걸려지도록 함으로써 종래에 발생된 문제점을 해결토록 한 것이다.Therefore, the present invention solves the problems that have occurred in the prior art by simply mounting the door lock device for opening and closing the door directly to the door without drilling or welding a hole in the cabin, and allowing the lock of the door to be caught on the pipe of the cabin. will be.

이를 위하여, 캐빈틀의 좌우 양측면에 장착되는 도어와 상기 도어의 캐빈틀의 파이프와 근접되는 프레임틀 내측에 장착되는 브라켓본체와 상기 브라켓본체에는 탄성수단과 상기 탄성수단에 의해 탄성에 의한 승강작동으로 상단의 걸림헤드가 캐빈틀의 파이프에 걸림되는 승강바가 장착되는 수용관을 형성하고, 상기 수용관에 장착된 승강바에는 레버가 연결되어 상기 레버의 작동으로 승강작동되면서 락이 해제되도록 한 것이다.To this end, the door mounted on the left and right sides of the cabin, the bracket body mounted inside the frame frame close to the pipe of the cabin of the door, and the bracket body are moved up and down by elastic means and the elastic means. The upper engaging head forms a receiving pipe in which an elevating bar that is hooked to a pipe of the cabin is mounted, and a lever is connected to the elevating bar mounted on the receiving pipe so that the lock is released by lifting and lowering by the operation of the lever.

따라서 본 발명에 의하면, 안전도 검사가 완료된 완성차로 제조된 지게차를 드릴가공이나 용접 등의 별도의 가공작업으로 캐빈틀을 전혀 손상시키지 않은 상태에서 도어의 개폐를 위한 도어락장치를 간단하게 장착토록 함으로써 안전도 재검사에 따른 시간소요나 비용이 발생되지 않고 판매나 수출이 가능하여 구조개선을 위한 제작업체나 소비자 모두에게 최상의 만족도를 제공할 수 있게 되는 것이다.Therefore, according to the present invention, by simply installing a door lock device for opening and closing the door in a state that does not damage the cabin by a separate processing operation such as drilling or welding on a forklift manufactured as a finished vehicle for which the safety inspection has been completed. It is possible to sell or export without incurring any time or cost due to re-inspection of safety level, thus providing the best satisfaction to both manufacturers and consumers for structural improvement.

도1 내지 도7에 도시된 바와 같이 본 발명의 구성은 탑승공간에 파이프상(21)으로 이루어진 캐빈틀(20)이 구비된 지게차(10)에 있어서, 상기 캐빈틀(20)의 좌우 양측면에 개폐되는 도어(30)가 장착되고, 상기 캐빈틀(20)의 탑승공간을 형성하는 도어(30)의 내측에 브라켓본체(100)가 장착되고, 상기 브라켓본체(100)에는 상단이 개구된 관상의 수용관(110)이 형성되고, 상기 수용관(110)에 탄성수단(120) 및 탄성수단(120)에 의해 탄성으로 승강작동되어 캐빈틀(20)의 파이프(21)에 걸림되어 락이 되고 락이 해제되어 개폐를 단속하는 승강바(130)가 수용되고, 상기 승강바(130)는 레버(140)가 연결되어 상기 레버(140)의 작동으로 승강작동되도록 한 것이다.1 to 7, the configuration of the present invention is a forklift 10 provided with a cabin 20 made of a pipe 21 in a boarding space, on both left and right sides of the cabin 20 The door 30 to be opened and closed is mounted, the bracket body 100 is mounted on the inside of the door 30 forming the boarding space of the cabin 20, and the bracket body 100 has a tubular shape with an open top The receiving pipe 110 is formed, and the receiving pipe 110 is elastically lifted and lowered by the elastic means 120 and the elastic means 120 to be locked by the pipe 21 of the cabin 20 The lock is released to accommodate the lifting bar 130 to regulate the opening and closing, and the lifting bar 130 is connected to the lever 140 so as to be moved up and down by the operation of the lever 140.

이때 상기 승강바(130)는 상단에 일측이 경사진 레치헤드(131)가 형성되어 상기 레치헤드(131)의 경사진 부분이 캐빈틀(20)의 파이프(21)에 접촉되면서 누름되어 승강바(130)가 탄성으로 하강되고 도어(30)과 완전히 닫히게 되면서 원상태로 복원되어 파이프(21)에 걸려지게 되고, 도어(30)의 개방은 레버(140)의 작동에 의해서 승강바(130)가 승강작동되어 걸림이 해제되면서 도어(30)의 개폐가 이루어지게 되는 것이다.At this time, the lifting bar 130 has a latch head 131 having one side inclined at the top thereof, and the inclined portion of the latch head 131 is pressed while contacting the pipe 21 of the cabin 20 to be pressed. As 130 is elastically lowered and completely closed with the door 30, it is restored to its original state and is hung in the pipe 21, and the opening of the door 30 is performed by the operation of the lever 140, so that the lifting bar 130 is The lifting operation is performed to release the jammed door 30 to be opened and closed.

또한 상기 승강바(130)의 저면에는 탄성수단의 상단이 끼워져 고정되는 끼임홈이 형성되고, 수용관의 저면에는 외측방향에서 볼트조임에 의해 내측에서 탄성수단의 하단을 고정하여 탄성수단이 임의적으로 유동되지 않게 고정하여 탄성작용이 용이하게 이루어지도록 한 것이다.In addition, the lower surface of the lifting bar 130 is formed with a fitting groove in which the upper end of the elastic means is fitted and fixed, and the lower end of the elastic means is fixed from the inside by tightening a bolt in the outer direction on the bottom surface of the receiving pipe, so that the elastic means is arbitrarily provided. It is fixed so that it does not flow so that the elastic action is easily achieved.

이때 상기 브라켓본체(100)는 승강바(130)의 레치헤드(131)가 걸림이 이루어지도록 캐빈틀(20)의 파이프(21)와 근접하는 도어(30)의 프레임틀에 장착되는 것이 바람직하며, 상기 브라켓본체(100)는 도어(30)의 프레임틀에 볼트조립 또는 용접에 의해 장착되고, 도어(30)의 프레임틀에는 브라켓본체(100)가 볼트조립으로 조립되는 조립홀이 형성된 장착면이 구비되는 것이다.At this time, the bracket body 100 is preferably mounted on the frame frame of the door 30 adjacent to the pipe 21 of the cabin 20 so that the latch head 131 of the lifting bar 130 is caught. , The bracket body 100 is mounted on the frame frame of the door 30 by bolt assembly or welding, and the frame frame of the door 30 has an assembly hole in which the bracket body 100 is assembled by bolt assembly. Is equipped with.

또한 상기 승강바(130)는 금속이나 고강력의 플라스틱이나 압착고무로 제조될 수 있으나, 도어(30)가 개폐되면서 승강바(130)의 레치헤드(131)에 의해서 캐빈틀(20)의 파이프(21)가 손상되지 않도록 하기 위하여 가능하면 고강도의 플라스틱 재질이나 압착고무로 제조되는 것이 바람직하다.In addition, the lifting bar 130 may be made of metal or high-strength plastic or compression rubber, but as the door 30 is opened and closed, the pipe of the cabin 20 is formed by the latch head 131 of the lifting bar 130. In order not to damage (21), it is preferable that it is made of high-strength plastic material or crimped rubber, if possible.

특히 상기 승강바(130)가 고강력의 플라스틱으로 제조될 경우에 두께가 있는 하나의 몸체로 형성될 수 있고, 또한 상기 승강바(130)가 복수 개의 면 조각이 중첩되어 하나의 몸체로 조립요소에 의해 조립되거나 접착으로 제조되어 개폐되는 충격에 의해서 보강이 이루어지게 되고 파손시에도 파손된 조각만 교체함으로써 원가를 절감할 수 있게 되는 것이다.In particular, when the lifting bar 130 is made of high-strength plastic, it may be formed as a single body having a thickness, and the lifting bar 130 is an assembly element as a single body by overlapping a plurality of face pieces. The reinforcement is made by the impact that is assembled or manufactured by bonding and is opened and closed, and even when damaged, only the damaged piece can be replaced, thereby reducing the cost.

이때 상기 수용관(110)의 일측면에는 절개라인(111)이 형성되고 상기 절개라인(111)을 통해서 레버(140)가 승강바(130)와 연결되게 장착되어 레버(140)가 절개라인(111)의 범위 내에서 상하로 승강작동이 이루어지면서 승강바(130)의 승강작동을 제어하게 되는 것이다.At this time, a cut line 111 is formed on one side of the receiving pipe 110 and the lever 140 is mounted to be connected to the lifting bar 130 through the cut line 111 so that the lever 140 is attached to the cut line ( It is to control the lifting operation of the lifting bar 130 while the lifting operation is made up and down within the range of 111).

즉, 레버(140)가 절개라인(111)의 상단부에 걸림되면서 승강바(130)가 수용관(110)에서 분리되는 것을 방지하고, 작동에 의해 레버(140)가 절개라인(111)의 하단부에 위치되면 승강바(130)가 누름가압되어 승강작동되면서 도어(30)의 개폐가 단속되는 것이다.That is, while the lever 140 is caught on the upper end of the cut line 111, the lifting bar 130 is prevented from being separated from the receiving pipe 110, and the lever 140 is operated at the lower end of the cut line 111 When it is located in the lifting bar 130 is pressed and pressed, the lifting operation, the opening and closing of the door 30 is regulated.

이때 상기 수용관(110)의 절개라인(111)이 형성된 방향에는 연장돌부(112)가 형성되어 상기 연장돌부(112)에 레버(140)가 승강바(130)를 승강작동하도록 장착되는 것이다.At this time, an extension protrusion 112 is formed in the direction in which the cut line 111 of the receiving pipe 110 is formed, and the lever 140 is mounted to the extension protrusion 112 to lift the lifting bar 130.

더욱 상세하게 설명하면, 상기 레버(140)는 수평의 연결부(141)와 수직의 작동부(142)로 이루어진 "ㄱ"자 형상으로 형성되어 상기 연결부(141)와 작동부(142)의 직교된 모서리 부분이 연장돌부(112)에 고정축(143)으로 축고정되어 상기 연결부(141)가 수용관(110)의 절개라인(111)을 통해서 승강바(130)와 연결되면서 절개라인(111)의 범위 내에서 이동되어 승강바(130)를 승강시키게 되고, 상기 연결부(141)는 작동부(142)의 가압에 의해서 축회전되면서 작동되는 것이다.In more detail, the lever 140 is formed in a "L" shape consisting of a horizontal connection part 141 and a vertical operation part 142 so that the connection part 141 and the operation part 142 are perpendicular to each other. The edge portion is axially fixed to the extension protrusion 112 by a fixed shaft 143 so that the connection part 141 is connected to the lifting bar 130 through the cut line 111 of the receiving pipe 110 and the cut line 111 It is moved within the range of to lift the lifting bar 130, and the connection part 141 is operated while being axially rotated by the pressure of the operation part 142.

또한 상기 작동부(142)의 하단에는 돌기(144)가 돌출되게 형성되고, 상기 돌기(144)에 고무캡(145)이 결합되어 작동부(142)의 작동시 고무캡에 의해서 손에 통증이 발생되지 않게 되는 것이다.In addition, a protrusion 144 is formed to protrude at the lower end of the operation unit 142, and a rubber cap 145 is coupled to the protrusion 144 so that pain in the hand is caused by the rubber cap when the operation unit 142 is operated. It will not occur.

이때 본 발명에서는 작동부(142)에 형성되는 별도의 돌기(144)에 의해서 고무캡이 장착되는 것으로 설명하고 있으나, 작동부(142)에 직접 고무캡(145)을 결합하여도 동일한 효과를 제공하게 되는 것이다.At this time, in the present invention, it is described that the rubber cap is mounted by a separate protrusion 144 formed on the operation part 142, but the same effect is provided even if the rubber cap 145 is directly coupled to the operation part 142. It is done.

이때 상기 승강바(130)에는 레버(140)의 연결부(141) 선단이 내삽되어 승강작동을 위한 가압공간이 형성되도록 수용관(110)의 절개라인(111)과 대응하는 길이의 절개라인(132)이 형성되는 것이다.At this time, a cutting line 132 having a length corresponding to the cutting line 111 of the receiving pipe 110 is formed so that the front end of the connection part 141 of the lever 140 is inserted into the elevation bar 130 to form a pressurized space for elevation operation. ) Is formed.

따라서 작동부(142)의 누름가압으로 축회동되는 연결부(141)가 절개라인(132)의 가압공간에서 이동이 가능되면서 승강을 위한 누름작동이 용이하게 이루어지게 되는 것이다.Therefore, the connection part 141 axially rotated by the pressing pressure of the operation part 142 can be moved in the pressing space of the incision line 132 and the pressing operation for lifting and lowering is easily performed.

또한 상기 레버(140)는 수용관(110)의 절개라인(111)과 동일선상으로 위치토록 하면서 축회동시 연장돌부(112)와 밀착면적을 최소화하여 레버(140)가 용이하게 작동될 수 있도록 연장돌부(112)와 레버(140)의 사이에는 이격와샤(113)가 장착되는 것이다.In addition, the lever 140 is positioned in the same line with the cut line 111 of the receiving tube 110 and minimizes the contact area with the extension protrusion 112 during axis rotation so that the lever 140 can be easily operated.
