Abstract

A roof rack structure may include a roof rail, which is hollow, including a hook coupling portion formed at one end portion or both end portions of a lower portion of the roof rail in a width direction thereof and integrally formed to extend in a length direction of a vehicle, and a pad including a pad hook formed at one side portion or both side portions of the pad in a width direction thereof such that the hook coupling portion of the roof rail is inserted into the pad hook, the pad formed to extend in the length direction of the vehicle.

First claim

What is claimed is:

1 . A roof rack structure comprising:
a roof rail, which is hollow, including a hook coupling portion formed at one end portion or both end portions of a lower portion of the roof rail in a width direction thereof and integrally formed to extend in a length direction of a vehicle; and a pad including a pad hook formed at one side portion or both side portions of the pad in a width direction thereof such that the hook coupling portion of the roof rail is inserted into the pad hook, the pad formed to extend in the length direction of the vehicle.

2 . The roof rack structure of claim 1 , wherein the roof rail further includes:
at least two mounting holes formed at an upper portion of the roof rail; and first bolt holes, disposed at positions corresponding to the at least two mounting holes, formed at a lower portion of the roof rail.

3 . The roof rack structure of claim 2 , wherein the pad further includes second bolt holes at positions corresponding to the first bolt holes.

4 . The roof rack structure of claim 3 , further comprising:
bolts fixedly mounted on a roof of a vehicle body such that the bolts respectively pass through the second bolt holes of the pad and the first bolt holes of the roof rail sequentially; and nuts coupled to the bolts and thereby fixing the roof rail and the pad to the roof of the vehicle body.

5 . The roof rack structure of claim 2 , further comprising:
mounting caps inserted into the at least two mounting holes such that the mounting caps close the at least two mounting holes.

6 . The roof rack structure of claim 1 , wherein:
an upper end portion of the pad hook is disposed at an upper side of the hook coupling portion and a lower portion of the pad hook is disposed at an inner side in the width direction of the roof rail with respect to the hook coupling portion, on a cross-section of the roof rack structure, the cross-section being perpendicular to a length direction of the roof rail.

7 . The roof rack structure of claim 1 , wherein:
the hook coupling portion protrudes towards an inner side in the width direction of the roof rail, on a cross-section of the roof rack structure, the cross-section being perpendicular to a length direction of the roof rail.

8 . The roof rack structure of claim 1 , wherein the pad hook comprises at least two hooks protruding towards an upper side of the pad and formed towards in a length direction of the pad.

9 . The roof rack structure of claim 4 , further comprising:
spacers, each spacer having a third bolt hole formed therethrough and coupled to each of the bolts through the corresponding third bolt hole to adjust or fill a gap between the pad and the roof.

10 . The roof rack structure of claim 9 , wherein:
the spacers are respectively mounted to the lower portion of the roof rail through the second bolt holes and the first bolt holes.

11 . The roof rack structure of claim 10 , wherein:
a lower portion groove is formed on an upper surface of the lower portion of the roof rail, the lower portion groove extending in the length direction of the vehicle, and spacer hooks, each being fitted on the lower portion groove by passing through each of the first bolt holes, are formed respectively on upper portions of the spacers.

12 . The roof rack structure of claim 11 , wherein each of the spacer hooks comprises
two protruding hooks respectively protruding towards upper sides at both sides of the corresponding third bolt hole in the length direction of the vehicle.

13 . The roof rack structure of claim 1 , wherein at least two coupling holes are formed on the lower portion of the roof rail, and coupling protrusions coupled to the at least two coupling holes protrude from an upper surface of the pad.

14 . The roof rack structure of claim 13 , wherein:
two coupling steps are formed at both sides of each of the at least two coupling holes in the length direction of the vehicle, and a hook head is formed at each of the coupling protrusions, the hook head fitted on the two coupling steps by passing through each of the at least two coupling holes.

15 . The roof rack structure of claim 1 , wherein:
the roof rail further comprises hook portions, each being hook-shaped and formed towards inner sides in the width direction of the roof rail from both side ends of a lower portion of each of both end portions of the roof rail in the width direction of the roof rail, and wherein: the pad further comprises locking wings formed at both end portions of the pad and inclined from an outer side towards an inner side in a length direction of the pad, such that the hook portions are fitted and locked into the locking wings by being placed from the inner side towards the outer side in the length direction of the pad.

16 . The roof rack structure of claim 15 , wherein the pad further comprises support portions inclined from the inner side towards the outer side in the length direction of the pad to support the locking wings.

17 . The roof rack structure of claim 15 , wherein:
both ends of the roof rail are respectively placed and locked into fitting portions formed at both end portions of the pad, from top to bottom.
