Description

루프랙 및 루프랙 제조 방법Roof rack and roof rack manufacturing method
본 발명은 차량용 루프랙 및 루프랙의 제조방법에 관한 것이다.The present invention relates to a roof rack for a vehicle and a method of manufacturing the roof rack.
일반적으로, 차량을 이용한 화물의 이송은 차량의 트렁크를 이용하게 되는데, 트렁크 공간을 이용하기 어려운 큰 부피의 화물이나 길이가 긴 화물의 경우에는 루프랙을 이용하여 이송하게 된다.In general, the transportation of cargo using a vehicle uses the trunk of the vehicle. In the case of a large volume of cargo or a long cargo that is difficult to use the trunk space, the cargo is transported using a roof rack.
그리고 루프랙은 차량의 지붕 상면인 루프 패널(roof panel)에 고정 되고, 캠핑장비나 스키와 같은 레저장비 등 비교적 부피가 큰 화물은 루프랙에 적 재시킨다. 요즘에는 레저용 차량(SUV; Sport Utility Vehicle, RV; Recreational Vehicle)의 대중화 및 캠핑 등의 레저여행의 붐과 함께 루프랙이 널리 사용되고 있 는 실정이다.And the roof rack is fixed to the roof panel, which is the upper surface of the vehicle, and relatively bulky cargo such as camping equipment and leisure equipment such as skis is loaded on the roof rack. Nowadays, roof racks are widely used with the boom of leisure travel such as popularization of camping and recreational vehicles (SUVs) and camping.
그러나 종래기술에 따른 루프랙은 레일과 스텐션이 분리되지 않는 일체형으로 고온으로 압출 성형하는 방식으로 제조되고 있으나, 냉각과정에서 수축에 의한 휨 또는 형상변형이 발생되고, 싱크마크(Sink mark)가 형성되는 문제점을 지니고 있다. 즉, 레일 내측 구조에 의한 외관 수축(Sink Mark)으로 제품의 상품성이 현격이 저하되는 문제점이 있다.However, the roof rack according to the prior art is manufactured by extruding at a high temperature as an integral type in which the rail and the stent are not separated, but bending or shape deformation due to shrinkage occurs during cooling, and a sink mark is formed. Has a problem. That is, there is a problem in that the merchandise of the product deteriorates due to the shrinkage of the appearance due to the inner structure of the rail.
본 발명은 상술한 문제점을 해결하고자 안출된 것으로, 루프랙의 레일과 스텐션을 각각 별개로 사출 성형하여 분리 제작하고 이를 진동 용착에 의해 접합함에 따라, 레일의 수축을 방지하고, 싱크마크 형성에 따른 외관품질 불량을 미연에 차단하여 외관 품질이 확보된 루프랙을 제공하는데 그 목적이 있다.The present invention has been devised to solve the above-mentioned problems, and the rails and the stents of the roof rack are separately molded and manufactured separately, and as they are joined by vibration welding, the rails are prevented from contracting and the sink marks are formed. The purpose of the invention is to provide a roof rack having an appearance quality secured by blocking appearance defects.
