[Problems to be solved by the device]

 In the conventional air conditioner duct 106 for a vehicle as described above, since the portion that enters the roof 104 side is long and the flatness is limited, the distance between the head H of the boarding vehicle and the roof 104 at this portion is sufficient. However, there is a problem that it gives passengers a narrow feeling. Further, as shown in FIG. 6, the pipe portion is elongated from the mounting flange 105 to one side, and the mounting is also cantilevered. Therefore, the moment to the mounting portion due to the vertical vibration of the vehicle increases, and the mounting flange 105 There is also a problem that the deterioration progresses quickly. Further, as shown in FIG. 7, since the air conditioner duct 106 is located directly above the assist grip 108 fixed to the roof side rail portion 102 together with the air conditioner duct 106, the upper side of the assist grip 108 becomes narrower and the assist grip 108 is narrowed. There is also a drawback that it becomes difficult to grip.

Therefore, the present invention has been made in order to solve the above-mentioned conventional inconvenience, and an object thereof is to provide a vehicle air conditioner duct in which a stable mounting state can be obtained with a small number of parts without lowering the roof. To do.

[Means for Solving the Problems]

 An air conditioner duct for a vehicle according to the present invention that solves the above-mentioned problems is an air conditioner duct that is piped along the inside of a roof side rail portion of a vehicle and has an outlet to the inside of the vehicle. A hollow, flat bulging part that overlaps the inner surface of the interior part of the main part is continuously connected to the lower part of the main pipe part so that the cross-sectional area corresponding to the cross-sectional area of this bulging part is the roof of the main pipe part. The main pipe part is reduced in the side part, and an attachment structure that can be fixed to the roof side rail part together with the assist grip by the assist grip attachment parts is provided in several places of the bulge part in the plane of the bulge part. Is.

[0006]

[Action]

 According to the above means, the cross-sectional area required for the ventilation function is obtained by the hollow bulging portion and the main pipe portion which overlap the inner surface of the roof side rail portion on the indoor side, and the main pipe portion is formed by the bulging portion on the roof side portion. Since the overhang to the vehicle is small, the roof of the vehicle does not become low, and the bulge itself connected to the main pipe can be fixed to the roof side rail together with the assist grip.

[0007]

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS. FIG. 2 shows a vehicle S to which the air conditioner duct 1 of this embodiment is applied. As shown in FIG. 3, this air-conditioner duct 1 is installed in a substantially U shape along the inside of the left and right roof side rail portions 2 (see FIG. 1) of the vehicle S and along the rear roof side portions. There is. The air conditioner duct 1 is mainly composed of the left and right roof side rail portions 2, and the rear portion is a connecting portion. As shown in FIG. 2, the air conditioner duct 1 is configured to be connected to the cooling unit 20 via a blower pipe 21 to allow ventilation.

FIG. 1 is an enlarged cross-sectional view taken along the line AA of the roof side portion in FIG. 2. The air-con duct 1 is a synthetic resin molded product obtained by blow molding or the like, and is partially blown out into the vehicle. A hollow, flat bulge 4 which has an outlet 3 as a mouth and overlaps with the inner surface of the roof side rail 2 which is the body structure of the vehicle S on the indoor side is integrally connected to the lower portion of the main pipe 5 in a connected state. I have it. Both the bulging portion 4 and the main pipe portion 5 have continuous internal spaces and function as ventilation channels.

The main pipe portion 5 is configured by reducing the cross-sectional area corresponding to the cross-sectional area of the bulging portion 4 on the roof 6 side portion, and the overall shape of the bulging portion 4 and the main pipe portion 5 is as shown in FIG. As shown in Fig. 4, it is a deformed isosceles triangle with a large apex angle. The surface in contact with the roof side rail portion 2 is formed so as to match the profile of the inner surface of the roof side rail portion 2, and the inside surface of the vehicle is formed so as to follow the profile of the roof 6 in an arcuate state.

As shown in FIG. 4, the bulging portion 4 is formed with a set of two mounting holes 7 arranged side by side in several places. Each of the mounting holes 7 is not in communication with the internal space, and constitutes a mounting structure in which a cylindrical collar 8 is fitted and mounted. The air duct 1 of the vehicle S is mounted by fastening a screw 9 to the roof side rail portion 2 via a collar 8 of a mounting structure. The pair of mounting holes 7 are formed so as to correspond to the intervals of the fixing portions of the assist grips 10, and the assist grips 10 are also fastened together by the screws 9 used for fixing the air conditioner duct 1. . As shown in FIG. 4, a mounting piece 15 is provided at an appropriate position on the side of the roof side rail portion 2 of the air conditioner duct 1, and the mounting piece 15 is screwed to the roof side rail portion 2 to fix the air conditioner. The duct 1 for the vehicle is safely fixed.

In the air conditioner duct 1 having the above structure, the cross-sectional area required for the ventilation function is ensured by the hollow bulging portion 4 and the main pipe portion 5 which overlap the inner surface of the roof side rail portion 2 on the indoor side. As a result, the required amount of air can be ventilated in the duct, and air can be ventilated from the outlet 3 into the room as in the conventional case.

Further, since the main pipe portion 5 of the air conditioner duct 1 of the present embodiment has a small protrusion to the roof 6 side portion due to the bulging portion 4, it does not become a factor for lowering the roof 6 of the vehicle S. When fixed to the vehicle S, since it is fastened with the screw 9 by the mounting structure formed on the bulging portion 4 itself connected to the main pipe portion 5, the rigidity of the mounting portion is high and the stable mounting state is maintained for a long time. In this example, since the same screws 9 are fastened to the roof side rail portion 2 together with the assist grip 10, the number of fixed parts and the fixed structure can be reduced. Since the surface of the air conditioner duct 1 has an arcuate shape, the assist grip 10 located in the bulging portion 4 and the main pipe portion 5 are spaced from each other, and the difficulty in gripping the assist grip 10 is eliminated. According to this example, as shown in FIG. 1, the space above the passenger's head H can be widened.

[0013]

[Effect of device]

 According to the present invention, as is clear from the above description of the embodiments, the cross-sectional area required for ventilation function is obtained by the hollow bulging portion and the main pipe portion which overlap the inner surface of the roof side rail portion on the indoor side, The bulging portion of the main pipe portion reduces the protrusion to the roof side, so the vehicle roof does not become low, and the passenger's head and the roof can be widely spaced to eliminate the feeling of narrowness. it can. In addition, since the bulging part itself connected to the main pipe part can be fixed to the roof side rail part together with the assist grip, the rigidity of the mounting part is high and it can be maintained with stable and few mounting parts. Is also reduced.
