DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier rail support device for mounting a carrier on a vehicle roof.

[0002]

2. Description of the Related Art A conventional roof rack mounting structure, as exemplified in Japanese Utility Model Laid-Open Publication No. 3-61454, has a groove formed in a joint portion between a roof panel and a quarter panel, and a gate-shaped support of the roof rack. Is straddled,
Although the load applied to the roof rack is configured to act on the flat surfaces of the roof panel and the quarter panel through the gate-shaped support, the rigidity of the flat surfaces of the roof panel and the quarter panel is relatively low. In order to support a sufficient load by the rack, it is necessary to reinforce the panel flat surface itself or to increase the seating area of the portal column with respect to the panel flat surface, which leads to an increase in complexity and size of the device. There was a fear.

SUMMARY OF THE INVENTION According to the present invention, a carrier rail for mounting a crossbar of a roof carrier is firmly and compactly supported in a concave portion formed at a joint portion between a roof panel of a vehicle and a side roof rail. It is intended to provide a device.

[0004]

SUMMARY OF THE INVENTION Accordingly, a carrier rail support device according to the present invention includes a recess formed in a joint portion between a roof panel and a side roof rail of a vehicle and extending in the front-rear direction of the vehicle, and a bottom surface of the recess. A hook formed so as to rise in the recess and a bracket extending in the recess to cover the edge of the recess in the width direction of the vehicle and sandwiching the hook, and a carrier rail is mounted on an upper portion of the bracket; It is configured as follows.

[0005]

In other words, the bracket covers the edge of the concave portion formed at the joint between the roof panel of the vehicle and the side roof rail, and the bracket sandwiches the hook formed so as to rise in the concave portion. Since the load applied to the carrier rail from the cross bar of the above will act on the relatively rigid concave portion via the bracket, the carrier rail can be firmly held by the support device having a compact structure. Is mounted on the upper portion of the bracket, so that the carrier rail can be mounted on the bracket after the bracket is fixed in the concave portion, so that the work of assembling the carrier rail can be easily performed.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention shown in the drawings will be specifically described below. 1 and 2, a concave portion 3 extending in the front-rear direction of the vehicle is formed at a joint portion between a roof panel 1 and a side roof rail 2 of the vehicle. Is provided with a hook portion 5 having a projection 4.

[0007] Brackets 6 are respectively arranged at three points in the recess 3 spaced apart in the front-rear direction of the vehicle.
Is composed of a resin-made bracket body 7 and a sheet metal holding member 8. The umbrella-shaped projections 10 of the bracket body 7 respectively cover the left and right edges of the concave portion 3, and the lower projections 11 of the bracket body 7. Are in contact with the bottom surface of the recess 3.

Further, a lateral projection 12 is formed from the lower projection 11 of the bracket body 7 toward the center of the vehicle to maintain the posture of the bracket body 7 in the recess 3. A notch 13 outward is formed at a substantially central portion in the vehicle front-rear direction, and a notch 1 is formed.
The holding member 8 fitted into the inside 3 is fixed to the bracket body 7 by the screw 14, and the hook portion 5 is sandwiched between the outer surface of the lower protrusion 11 and the lower portion of the holding member 8, and the holding member 8 is prevented from coming off by the protrusion 4. As a result, each bracket 6 is attached to the recess 3.

On the other hand, a carrier rail 16 is attached to the top surface of each bracket body 7 by a countersunk screw 15, and a soft edge molding 18 is fitted into the lower end of the outer skirt portion 17 over the entire length of the carrier rail 16. Then, the lower surface of the edge molding 18 abuts on the upper surface of the side roof rail 2 to close the gap between the carrier rail 16 and the upper surface of the side roof rail 2.

Further, resin end caps 20 are elastically fitted into the dovetail grooves 19 of the carrier rail 16 from the front and rear, respectively, so that the front and rear of the dovetail grooves 19 are closed, and further, as shown in FIG. The lid 21 integrally formed with the end cap 20 is opened outward to open the end of the groove 19, so that the slide plate 22 is removably inserted into the groove 19, and slides. Bolt 23 is welded to plate 22.

As shown in FIGS. 4 and 5, a carrier base 25 is fixed to both ends of each of the two front and rear crossbars 24, and is mounted on the carrier rail 16, and has a dovetail groove 1.
The nuts 26 are screwed from inside the carrier base 25 into the bolts 23 on the slide plate 22 which project upward from the inside of the carrier base 25 and pass through the bottom of the carrier base 25, so that the crossbars 24 are spaced above the roof panel 1. And a roof carrier is configured.

In the above-described apparatus, the load due to the load attached to each crossbar 24 is sequentially applied to the crossbar 24,
The bracket 6 acts on the bracket 6 via the carrier base 25 and the carrier rail 16, but the main vertical load is supported by the left and right edges of the concave portion 3 and the bottom surface of the concave portion 3 from the projecting portion 10 and the lower protrusion 11 of the bracket body 7, respectively. In addition, the load acting in the width direction of the vehicle is supported by the side walls of the concave portion 3 and the hook portion 5. In this case, the concave portion 3 has a relatively large rigidity due to its bent structure. Can be held firmly, so that the above load can be easily supported,
The strength as a roof carrier can be easily increased.

The bracket 6 for supporting the carrier rail 16 has a compact and simple structure that straddles the left and right edges of the recess 3, while the holding member 8 is attached to the bracket body 7 disposed in the recess 3 by screws 14. When the hook 6 is clamped between the lower protrusion 11 of the bracket body 7 and the holding member 8, the bracket 6 can be easily attached to the recess 3 and the bracket 6 can be attached to the recess 3. After that, the carrier rail 16 can be attached to the top surface of the bracket body 7 with the screw 15, so that the work of assembling the carrier rail 16 using the bracket 6 can be performed easily, and the bracket 6 can be attached by the carrier rail 16. The cover can be surely covered to improve the appearance and the commercial value can be easily increased.

[0014]

In the carrier rail support device according to the present invention, the bracket covers the edge of the concave portion formed at the joint between the roof panel of the vehicle and the side roof rail, and the hook portion is formed so as to rise in the concave portion. And the load applied to the carrier rail from the crossbar of the roof carrier acts on the relatively rigid recess through the bracket, so the support rail with a compact structure firmly supports the carrier rail. Since the carrier rail can be held and the carrier rail is attached to the upper part of the bracket, the carrier rail can be attached to the bracket after the bracket is fixed in the concave portion, making it very easy to assemble the carrier rail. Yes, and cover the bracket with the carrier rail. A manner, it is also possible to satisfactorily retain their appearance.
