Description

드릴 작업 없이 장착되는 지게차 캐빈용 도어 및 창틀의 개선된 장착구조{Improved mounting structure for doors and window frames for forklift cabins mounted without drilling}Improved mounting structure for doors and window frames for forklift cabins mounted without drilling}

본 발명은 드릴작업 없이 지게차 캐빈의 틀에 장착되는 도어 및 창틀을 장착구조를 개선하여 장착을 위한 조립이 용이하고 미려한 외관을 제공하면서 도어를 필요에 따라 탈부착 가능하게 장착할 수 있도록 한 것이다.The present invention improves the mounting structure of a door and a window frame mounted on the frame of a forklift cabin without drilling, and allows the door to be detachably mounted as needed while providing an easy and beautiful appearance for assembly.

현재 지게차는 중공상의 파이프로 이루어진 탑승공간을 위한 캐빈틀이 구비된 완성된 차로 제조되고, 캐빈틀 내부에는 지게차의 구동에 필요한 전선이 배선되어 미관을 해치지 않으면서 전선을 보호하도록 제작되는 것이다.Currently, the forklift is manufactured as a completed car equipped with a cabin for a boarding space made of hollow pipes, and inside the cabin, wires necessary for driving the forklift are wired to protect the wires without harming the aesthetics.

또한, 완성된 지게차는 운행중에 발생할 수 있는 충격이나 전복사고 등의 안전도를 위한 차체에 대한 전반적인 안전시험이 이루어지고, 이러한 안전시험을 통과하여 승인받은 상태에서 판매가 이루어지는 것이다.In addition, the completed forklift is subjected to an overall safety test for the vehicle body for safety such as an impact or rollover accident that may occur during operation, and is sold in an approved state after passing the safety test.

그러나 대부분의 지게차의 캐빈틀은 천정과 전면창과 후면창 그리고 양측에 도어가 구비되지 않은 상태로 판매가 이루어지기 때문에, 대부분의 구매자들은 지게차가 사용되는 장소나 환경에 따라서 구매자의 요구에 의해 지게차 캐빈을 전문으로 제작하는 별도의 업체를 통해서 천장과 전면창과 후면창과 도어를 장착하게 되는 것이다.However, most forklift cabins are sold without ceilings, front windows, rear windows, and doors on both sides, so most buyers need to purchase forklift cabins according to the buyer's request depending on the location or environment where the forklift is used. The ceiling, front window, rear window, and door will be installed through a separate company that specializes in production.

예를 들어, 창고와 같은 실내에서만 지게차가 작업운행될 경우에는 최초의 완성된 지게차로 사용 가능하지만 지게차가 외부에서 작업운행이 이루어질 경우에는 비나 눈이 내리는 날과 날이 더운 하절기나 날이 더운 동절기의 계절에 따라서 탑승자의 작업효율을 높이기 위하여 캐빈틀에 전면창과 후면창만 설치하여 사용되거나 전면창과 후면창과 함께 양측에 도어를 개폐가능하게 장착하여 사용하게 되는 것이다.For example, if the forklift is operated only indoors, such as a warehouse, it can be used as the first completed forklift, but when the forklift is operated outside, when rain or snow falls and when the day is hot or during the hot summer days According to the season, only the front and rear windows are installed in the cabin to increase the working efficiency of the occupants, or the doors are opened and closed on both sides together with the front and rear windows.

그러나 종래에는 캐빈틀에 천정은 물론 전면창과 후면창과 도어를 장착하기 위하여 용접의 방법으로 장착하였으나, 이러한 것의 문제가 용접열에 의해 전기배선이 녹는 등의 문제가 발생하여 대부분 드릴링 작업에 의하여 나사조임이 가능한 드릴구멍을 천공하여 볼트조립에 의해 장착하게 되는데, 이런 경우에도 드릴구멍 천공에 따른 전기배선이 훼손되어 화재나 오작동의 문제가 발생되는 문제가 있고, 특히 충격이나 전복사고 등에 대해 안전검사를 통과한 지게차에 드릴구멍을 천공함으로써 구조개선에 따른 안전도 검사를 재승인 받아야 하고, 그에 따른 시간과 비용이 발생되는 문제가 있었으며, 특히 해외로 수출되는 지게차는 안전도 검사과정이 매우 까다로워 매우 큰 경제적인 손실이 발생되었다.However, in the prior art, the ceiling was mounted on the cabin as well as the front window, the rear window, and the door. However, the problem of this was that the electric wiring melted due to welding heat, and most of the screws were screwed by drilling. The drill hole is drilled as much as possible to install it by bolt assembly. Even in this case, there is a problem that a fire or malfunction occurs due to the damage to the electrical wiring caused by the drill hole drill, and in particular, the safety inspection is passed for shock or rollover accidents. Drilling a drill hole in a forklift requires re-approval of safety inspection due to structural improvement, and there is a problem that time and cost are incurred. In particular, forklifts exported overseas are very demanding, so the safety inspection process is very difficult. Phosphorus loss occurred.

따라서 본 발명의 출원인이 특허출원하여 등록받은 특허등록 제10-1879157호후방파이프의 외측으로 도어가 경첩브라켓에 의해 장착되는 도어장착바와 후면창틀을 서로 맞물려지는 체결부로 체결하고 후방파이프의 내측에는 연결브라켓을 연결브라켓으로 동시에 체결하여 드릴구멍을 천공하지 않은 상태에서 캐빈틀에 후면창과 도어를 장착토록 하였다. Therefore, the applicant of the present invention is applied to the inside of the rear pipe by fastening the door mounting bar and the rear window frame to which the door is mounted by a hinge bracket to the outside of the rear pipe of patent registration No. 10-1879157 registered by applying for a patent and connected to the inside of the rear pipe. At the same time, the bracket was fastened with a connecting bracket so that the rear window and door were mounted on the cabin without drilling holes.

그러나 이러한 것의 단점은 조립과정이 복잡할 뿐만 아니라 조립에 필요한 많은 시간이 소요되면서 캐빈틀 제조에 따른 생산의 어려움이 있었고, 체결부분이 지게차 외부로 노출되면서 지게차의 외관디자인이 저하되는 단점이 있었다.However, the disadvantages of this were that the assembly process was complicated, and it took a lot of time to assemble, making it difficult to produce the cabin, and the exterior design of the forklift was deteriorated when the fastening part was exposed to the outside of the forklift.

특히 등록된 특허발명의 문제점은 도어장착프레임과 후면창틀이 반드시 동시에 장착되는 구조로 이루어짐으로써 도어가 필요하지 않을 경우에도 도어장착을 위한 불필요한 도어장착프레임이 장착됨으로서 불필요한 작업공정을 요구하게 될 뿐만 아니라, 제조단가가 상승되는 문제점이 존재하게 되는 것이다.Particularly, the registered patent invention has a structure in which the door mounting frame and the rear window frame are mounted at the same time, so that even when a door is not required, an unnecessary door mounting frame for mounting the door is installed, which requires unnecessary work process. , There is a problem that the manufacturing cost increases.
