Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention relates to a mounting structure for a resin molded product that is fixed to a vehicle body by tightening a resin molded product such as a quarter window molding with bolts and nuts. .

(Prior Art) As shown in FIG. 5, a sedan-type passenger car is equipped with a quarter window 2 on a rear pillar 1 so as to enhance the lighting of the passenger compartment or to see the outside scenery from the quarter window 2. There is something I did.

By the way, the quarter window 2 is fixed to the mounting seat 7 of the rear pillar 1 by normally tightening the nuts 5 on the four bolts 4 as shown in FIGS. 6 and 7.
That is, the rear pillar 1 is provided with an opening 6 having substantially the same shape as that of the quarter window 2, and the mounting seat 7 around the opening 6 is provided with four mounting holes 8 in each of two front and rear. There is. On the other hand, the quarter window 2 is formed by insert-molding a total of four bolts 4 in a resin window molding 9 so as to face the mounting holes 8 respectively, and attaching the molding 9 to the periphery of the window glass 10. ing.
Reference numeral 11 is an insert member that is embedded in the molding 9 and holds the window glass 10 and has an L-shaped vertical cross section. Then, from the outside to the mounting seat 7 of the rear pillar 1, a quarter window
Dispose 2 and insert each bolt 4 into each mounting hole 8.
The quarter window 2 is fixed by tightening the nut 5 from the inside to the threaded portion 4a via the washer 12.

(Problems to be solved by the invention) However, when fixing the quarter window 2 by tightening the nuts 5 on all four bolts 4 as in the above-described conventional case,
When the nuts 5 are tightened to the bolts 4 one by one and the three bolts 4 are tightened, the mounting position of the quarter window 2 with respect to the mounting seat 7 is determined, and as shown in FIG. There was a problem that the surrounding wind molding 9 was locally lifted from the mounting seat 7 and deformed, and particularly when the wind molding 9 was soft, the deformation was remarkable and the appearance was spoiled.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a mounting structure for a resin molded product that can be mounted without causing local deformation when mounting the resin molded product. Especially.

[Constitution of device]

(Means and Actions for Solving Problems) In the present invention, when a resin molded product is attached by tightening nuts to four or more bolts provided on the resin molded product, at least one of the bolts is the same. It is fixed to the panel by the resin clip that is locked to the bolt. The resin clips are opposed to each other and are elastically deformed in the radial direction when the threaded portion of the bolt is pushed between them and the threaded portion. And a flange portion that comes into contact with the panel and is elastically deformable.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. However, in FIGS. 1 to 4,
The same parts as those in FIGS. 5 to 8 are designated by the same reference numerals, and the description thereof will be omitted.

In FIGS. 1 and 2, a resin clip 21 described later is attached to one of the four bolts 4 protruding from the wind molding 9 to attach the wind molding 9 to the mounting seat 7.
While the nut 5 is fastened to the remaining three bolts 4 in the same manner as in the conventional case. That is, the clip 21 is attached to one of the four bolts 4, and the wind molding 9 is attached to the attachment seat 7 by the three nuts 5 and the one clip 21.

Next, the clip 21 will be described. As shown in FIGS. 3 and 4, the clip 21 has an elastically deformable flange portion 22, and a central portion of the flange portion 22 has a keyhole shape. An opening 23 is provided. Further, the flange portion 22 is provided with a pair of locking portions 25 projecting downward from the peripheral edge of the opening 23 and elastically deformable in the radial direction so as to face each other. A threaded surface 25a having a thread groove is provided inside the locking portion 25 so as to be screwed into the threaded portion 4a of the bolt 4. Further, these locking portions 25 are provided such that the lower side of the thread surface 25a thereof is inclined toward the center of the opening 23. Therefore, with such a clip 21, as shown in FIG. 1 and FIG.
If you push it into the opening 23 through the screw part 4a of the bolt 4,
The lower side of the screw surface 25a of each locking portion 25 elastically deforms in a direction away from each other, and the screw surface 25a locks with the screw portion 4a of the bolt 4. That is, the clip 21 is locked simply by pushing it in the axial direction with respect to the bolt 4, and is held immovably in the axial direction.

Then, when fixing the quarter window 2, first, one nut 5 is tightened to each of the three bolts 4 out of the four bolts 4 inserted into each mounting hole 8. Here, the mounting position of the quarter window 2 with respect to the mounting seat 7 is determined.
Then, as shown in FIGS. 1 and 2, the clip 21 is pushed into the remaining one bolt 4 and locked.

As a result, the remaining one bolt 4 can be fixed like the other three bolts, and the tightening force of the clip 21 is weaker than that of the nut 5, so that the wind molding 9 around the remaining one bolt 4 is It is possible to prevent it from being locally lifted or deformed by being depressed. Thus, the quarter window 2 without causing local deformation in the wind mall 9
Can be correctly fixed to the mounting seat 7 of the rear pillar 1 at a predetermined mounting position, and the appearance can be prevented from being spoiled.

Further, the remaining one bolt 4 can be locked by pushing the clip 21 into the threaded portion 4a thereof.
There is no need to perform a tightening operation as in 5, so installation workability can be improved.

In addition, in the above-described one embodiment, the case where the quarter window is mounted on the mounting seat of the rear pillar is shown, but the present invention can be implemented even when other resin molded products, for example, a trim made of soft vinyl chloride is mounted on the door or the like. .

[Effect of device]

As described above, according to the present invention, when a resin molded product is fixed to a vehicle body panel by tightening nuts on four or more bolts, a resin clip is attached to a thread portion of at least one of the bolts. Since it is locked and attached, since the tightening force is weaker than that of the nut, it is possible to prevent local deformation even in a soft resin molded product. For example, when the panel is tightened with four bolts, three exert surface and holding force by the tightening force of the nut, and the remaining one bolt is locked with the resin clip to absorb the variation. be able to. That is, when the surface is formed by the three bolts, the remaining one bolt can be softly held by using the resin clip, so that the surface does not collapse.
