일 예로, 도 4에 예시된 도면에서는, 제1 측벽의 단면의 폭(w5)이 제2 측벽(130)의 단면의 폭(w6)보다 크기가 작은 폭을 가지므로, 베이스부(150)의 두께(w7)는, 제1 측벽의 단면의 폭(w5)의 0.3 내지 1.0배 또는 0.3 내지 0.7배를 가질 수 있다. As an example, in the drawing illustrated in FIG. 4, since the width w5 of the cross-section of the first sidewall has a smaller width than the width w6 of the cross-section of the second sidewall 130, the base portion 150 The thickness w7 may have 0.3 to 1.0 times or 0.3 to 0.7 times the width w5 of the cross section of the first sidewall.
예를 들어, 베이스부(150)의 두께(w7)가 베이스부의 제1면(151)과 동일 평면을 이루는 제1 측벽(110)의 단면의 폭(w5) 및 제2 측벽(130)의 단면의 폭(w6) 중 크기가 작은 폭의 0.3 미만으로 형성되거나 또는 1.0 초과 하여 크게 마련되는 경우, 루프랙을 사출 성형 시, 말림 현상 및 외관이 수축하는 문제가 발생할 수 있다.For example, the width w5 of the cross section of the first side wall 110 and the cross section of the second side wall 130 in which the thickness w7 of the base unit 150 is the same plane as the first surface 151 of the base unit If the size of the width w6 of the width (w6) is formed to be less than 0.3 of the small width or is provided larger than 1.0, when the roof rack is injection-molded, there may be a problem of curling and shrinkage of the exterior.

여기서, 상기 제2 부재(183,193)의 두께(폭)는 제1 부재의 두께(폭)보다 두껍게 마련될 수 있다.Here, the thickness (width) of the second members 183 and 193 may be thicker than the thickness (width) of the first member.
전술한 바와 같이, 본 발명의 레일(100)은 대략 'H' 형상을 가지며, 베이스부의 중심선(L1)을 기준으로 제1 측벽과 제2 측벽은 비대칭 구조를 갖게 된다.As described above, the rail 100 of the present invention has an approximately'H' shape, and the first sidewall and the second sidewall have an asymmetric structure based on the center line L1 of the base portion.
특히, 제1 측벽(110) 대 제2 측벽(130)의 단면적은, 1: 0.6 내지 1: 1을 갖도록 마련될 수 있다. In particular, the cross-sectional area of the first side wall 110 to the second side wall 130 may be provided to have a 1: 0.6 to 1: 1.
즉, 도 4의 빨간색으로 각각 표시된 부분(단면적)을 참조하면, 제1 측벽(110)의 단면적(A1)과 제2 측벽(130)의 단면적(A2)의 비율은, 제1 측벽(110)의 단면적(A1)이 1 일 때, 제2 측벽(130)의 단면적(A2)은 0.6 내지 1 의 비율을 가질 수 있다.That is, referring to the portions (cross-sectional areas) marked in red in FIG. 4, the ratio of the cross-sectional area A1 of the first sidewall 110 and the cross-sectional area A2 of the second sidewall 130 is the first sidewall 110 When the cross-sectional area A1 of is 1, the cross-sectional area A2 of the second sidewall 130 may have a ratio of 0.6 to 1.
보다 바람직하게, 제1 측벽(110)의 단면적(A1) 대 제2 측벽(130)의 단면적(A2)의 비율은 1: 0.6 내지 1:1, 또는 1: 0.7 내지 1:1, 또는 1: 0.8 내지 1: 1, 또는 1:0.9 내지 1:1, 또는 1: 0.95 내지 1:1, 또는 1:1 일 수 있다.More preferably, the ratio of the cross-sectional area A1 of the first sidewall 110 to the cross-sectional area A2 of the second sidewall 130 is 1: 0.6 to 1:1, or 1: 0.7 to 1:1, or 1: 0.8 to 1: 1, or 1: 0.9 to 1:1, or 1: 0.95 to 1:1, or may be 1:1.
상기와 같이 제1 측벽을 기준으로, 제2 측벽의 단면적의 비율이 전술한 값을 벗어나는 경우, 사출 성형 시 냉각 시간에 따른 수축율이 상이하게 되어 폭이 보다 두꺼운 측벽 측의 폭(너비) 방향을 따라 레일의 휨이 발생하게 되는 문제점이 발생한다.As described above, when the ratio of the cross-sectional area of the second side wall to the first side wall is out of the above-described value, the shrinkage rate according to the cooling time during injection molding is different, so that the width (width) direction of the side wall side with a thicker width is changed. Accordingly, there is a problem that the rail is bent.
본 발명의 레일(100)은 전술한 구조로 형성하여 제1 측벽과 제2 측벽의 단면적이 대략적으로 동일(단면적의 차이가 없는)하게 하여, 상기와 같은 단면적 비율을 갖도록 형성함으로써, 사출 성형 시, 수축에 의한 휨 발생을 방지할 수 있게 된다.The rail 100 of the present invention is formed in the above-described structure so that the cross-sectional area of the first side wall and the second side wall is approximately the same (there is no difference in cross-sectional area), and has the same cross-sectional area ratio. , It is possible to prevent the occurrence of warpage due to shrinkage.

또한, 상기 각각의 고정부(320; 320a, 320b)는 제1 및 제2 커버부(310,330)의 외주면을 따라 연장되어 제1 및 제2 커버부의 외관을 마감하도록 마련된 제2 레그(322; 322a, 322b)를 포함한다.In addition, each of the fixing parts 320; 320a, 320b extends along the outer circumferential surfaces of the first and second cover parts 310 and 330 to finish the appearance of the first and second cover parts 322; 322a. , 322b).
즉, 각각의 제2 레그(322a, 322b)는 레일에 장착되는 커버의 외관을 마감하도록 마련될 수 있다.That is, each of the second legs 322a and 322b may be provided to close the exterior of the cover mounted on the rail.
상기 각각의 제1 및 제2 레그(321,322)는, 제1 및 제2 커버부(310,330)의 종단부에서 서로 이격되어 분기되고, 각각의 제1 및 제2 레그(321,322) 사이에 소정의 공간을 형성하도록 마련된 중공부(323; 323a, 323b)를 포함하며, 각각의 중공부(323a,323b)는 하방이 개방되도록 마련될 수 있다.Each of the first and second legs 321 and 322 is separated from each other at the end portions of the first and second cover portions 310 and 330, and a predetermined space between each of the first and second legs 321 and 322 It includes a hollow portion 323 (323a, 323b) provided to form a, each of the hollow portion (323a, 323b) may be provided to be opened downward.
상기 제1 및 제2 레그(321,322)는 일 예로, 대략 'ㅅ'자 형태로 형성될 수 있다.As an example, the first and second legs 321 and 322 may be formed in an approximately'g' shape.
여기서, 상기 각각의 중공부(323)는 예를 들어, 사출 성형 시, '살빼기' 공정을 통해 형성될 수 있다.Here, each of the hollow portions 323 may be formed through, for example, a'weight loss' process during injection molding.
이에 더하여, 상기 각각의 제1 및 제2 레그(321,322) 각각의 두께는, 제1 및 제2 커버부(310,330)의 두께보다 얇게 형성될 수 있다.In addition, each of the first and second legs 321 and 322 may have a thickness smaller than that of the first and second cover portions 310 and 330.
상기와 같이, 레일에 커버를 고정시키도록, 제1 및 제2 커버부(310,330)의 종단부에 하방이 개방된 중공부(323)를 각각 마련함으로써, 제1 레그(321)는 레일과 커버를 고정시키는데 사용되고, 제2 레그(322)는 루프랙의 외관을 마감할 수 있는 구조를 가지므로, 커버의 외관 품질을 향상시킴과 동시에 레일과 커버의 조립 단차를 줄일 수 있는 효과가 있다.As described above, by providing a hollow portion 323 that is open downward at the end portions of the first and second cover portions 310 and 330 to fix the cover to the rail, the first leg 321 Since the second leg 322 has a structure capable of finishing the exterior of the roof rack, the second leg 322 has an effect of improving the appearance quality of the cover and reducing the assembly step between the rail and the cover.
또한, 제1 및 제2 레그 사이에 중공부를 형성함으로써, 커버의 사출 성형 시 커버의 휨을 방지할 수 있는 효과가 있다.In addition, by forming a hollow portion between the first and second legs, there is an effect of preventing bending of the cover during injection molding of the cover.
