Description

[Detailed description of the invention] The present invention relates to a mounting structure for a rocker molding to be attached to the lower end of a side wall of a vehicle body, that is, a rocker part. Specifically, the present invention relates to a mounting structure for a rocker molding that can be firmly fixed to the rocker part outer plate with screws. To provide a mounting structure for a rocker molding which can be attached to a rocker molding, and which prevents screws or working holes for tightening the screws from being exposed to the outside and spoiling the appearance of the rocker molding.

Rotsuka mall is one of the resin parts that has recently come to be attached to the exterior of the car body of sports type cars. In addition to its function of preventing stones and foreign objects from directly impacting the rocker section, it also serves as a decorative element that forms part of the lower exterior of the car body, giving it a sense of solidity.

Conventionally, as a mounting structure for resin parts including such a rock mold, for example,
As shown in Publication No. 194851, parts are attached using adhesive or double-sided adhesive tape, or integral clips are provided at multiple locations in the longitudinal direction on the back of resin parts, and these are attached to the outer panel of the vehicle body. There is one that is forcibly pushed into the mounting hole drilled in the hole. However, such a conventional mounting structure generally has a weak fixing force, and cannot be used as is as a mounting structure for a rock mall, which is likely to be hit hard by stones thrown up by the front wheels or by foreign objects.

The present invention was devised under the above-mentioned circumstances, and its purpose is to make it possible to firmly fix the locking part with screws, and to make the work simple and easy. To provide a mounting structure for a lock camole without damaging the appearance.

In order to achieve this purpose, in this invention,
The following technical measures have been taken:

In other words, the cross-sectional shape of the rocker mall is made up of a standing wall that extends downward while slightly bulging outward from the outermost outermost part in the vehicle width direction of the rocker part of the vehicle body, and a standing wall that extends substantially horizontally in the vehicle width direction from the lower end of this standing wall. The locking part is formed into a substantially L-shape with a bottom wall extending to the lower surface of the locking part, a retainer is provided on the back side of the locking part, and the retainer and the locking part outer plate are fixed with screws, and the above-mentioned A working hole for inserting a tool for turning a screw is opened in the bottom wall.

Lotsuka Mall itself has a slightly bulging wall,
It has a solid appearance with a bottom wall, and the guard effect of the vertical wall and bottom wall is outstanding.
In addition, as a result of having the standing wall and bottom wall as described above, the back side of the Rotsuka Mall in the mounting structure is
A space with a triangular cross section is formed surrounded by the standing wall, the bottom wall, and the rocker section outer panel. Since it is fixed by the rocker molding, the attached state is stronger, more reliable, and more stable than, for example, when only the contact portion between the rocker molding and the rocker part outer plate is bonded. In addition, in order to screw the retainer provided in the above-mentioned space to the outer plate of the rocker part, it is necessary to provide a working hole in the rocker molding for inserting a screwdriver tool. Since the hole is provided in the bottom wall from the lower edge of the standing wall to the bottom of the rocker section, this working hole cannot be seen from the outside, and there is a concern that the working hole will spoil the appearance of the rocker mall. Nor.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the rocker molding 1 is attached to the lower ends of the left and right side walls of the vehicle body 2, that is, to the outer plate of the rocker portion 3.

As shown in cross section in FIGS. 2 and 3, this rocker molding 1 includes a standing wall 4 that extends downward while slightly bulging outward from the outermost end in the vehicle width direction of the rocker portion 3, and It is a member having a substantially L-shaped cross section and a bottom wall 5 extending inward in the vehicle width direction from the lower edge of the wall 4 to the lower surface of the rocker part 3, and is a member of the rocker part between the front tire house and the rear tire house. It has a longitudinal dimension corresponding to the length.

As shown in FIG. 2, this rocker molding 1 is fixed mainly on the back side by fixing the attached retainer 6 and the outer plate 7 of the rocker part 3 with screws 8, and also on the bottom. The wall 5 is directly fixed to the outer panel 7 with screws 9. However, in this example, the retainer 6 is attached to the back surface of the rocker molding 1 so that it can have some play in the longitudinal direction, and the screw hole 10 to be bored in the bottom wall 5 has a diameter larger than the diameter of the screw. Since it is a wide hole or an elongated hole, the elongation or contraction in the longitudinal direction of this rockamoll is absorbed.
The screw 9 in this section is a stepped screw having a larger diameter at the portion that is inserted into the screw hole 10.

In the illustrated example, the structure for attaching the retainer 6 to the rocker molding 1 is as follows.

A retainer attachment piece 11 is integrally formed on the back surface of the upper part of the standing wall 4 of the Rotsuka mall 1, and the bottom wall 5
A retainer attachment part 12 is provided at a location corresponding to the retainer attachment piece 11 in the longitudinal direction of the lockcamole, and elongated holes 13 and 14 are formed in each of the retainer attachment piece 11 and the retainer attachment part 12 in one longitudinal direction of the lockcamole. On the other hand, clip fitting holes 17 and 18 are formed in the upper and lower pieces 15 and 16 of the retainer 6, and these elongated holes 1
3 and 14 and the clip insertion holes 17 and 18 in communication with each other. The hooking part at the tip of the clip 19 inserted in this way is caught on the retainer attachment pieces 11 and 12, and the retainer attachment piece 11 and the retainer 6 and the retainer attachment part 12 and the retainer 6 are detached in the axial direction of the clip 19. There will be no. As a result, the retainer 6 can play with respect to the rocker molding 1 only in the longitudinal direction of the rocker molding 1 within the range permitted by the elongated holes 13 and 14. In this case, as shown in FIG. 3, if a short protrusion 20 is formed on the retainer attachment part 12 of the bottom wall 5 of the rocker mall 1 to restrain the side part of the retainer 6, the retainer 6 can be easily attached. When attaching it to the rocker molding 1, it is convenient because the attachment position in the longitudinal direction can be easily determined and the work can be carried out quickly. Note that this protrusion 20 is only for the convenience of attaching the retainer 6 to a predetermined position, so if the locking molding 1 expands or contracts after the locking molding 1 is installed, it may be caused by the side edge of the retainer 6. It does not matter if it is scratched, scraped, or crushed.

The rocker molding 1 with the retainer 6 attached in this manner is attached to the rocker part by fixing the retainer 6 and the rocker part outer plate 7 to each other with screws 8.

That is, a screw hole 21 is provided in the middle part of the retainer 6, and the screw 8 inserted into the screw hole 21 is inserted into the nut 23 fixed in advance on the back side of a mounting hole 22 made in the outer plate 7 of the rocker part.
It is finally attached by screwing it to the To tighten this screw 8, a working hole 24 for inserting a tool is made in the locking molding 1, and the tool 25 is inserted into the internal space of the locking molding 1 from there.
However, in the present invention, a working hole 24 is provided in the bottom wall 5, as clearly shown in FIG. 2. Therefore, this working hole 24 cannot be visually recognized from the side of the vehicle body, and there is no fear that the working hole 24 will spoil the appearance of the rock mall 1 or, by extension, the appearance of the vehicle body. Note that if the working hole 24 is covered with a plug 26 made of rubber, for example, after the locking molding 1 is attached to the locking part 3, raindrops may enter through this working hole and cause rust on the retainer and screws. can be effectively prevented.

Note that before tightening the screws 8, the retainer 6
If a gasket 27 is interposed between the outer plate 7 and the outer plate 7 of the rocker part, the mounting hole 2 made in the outer plate
This is advantageous because it can prevent raindrops from entering the locker part.

In this example, the retainer 6 is fixed to the rocker part outer plate 7, but the retainer 6 is fixed to the rocker part outer plate 7.
is capable of shifting in the longitudinal direction with respect to the retainer 6 within the range permitted by the elongated holes 13 and 14. Therefore, even if the rockamoll 1 expands or contracts due to heat, the amount of expansion and contraction is absorbed by the elongated holes 13 and 14. In addition,
In this case, the amount of change due to heat increases toward the end of the rocker molding, but in order to average out the amount of change at both the front and rear ends, it is preferable to keep only the central portion of the rocker molding 1 fixed relative to the rocker portion. For this purpose, among the retainer attachment pieces 11 and retainer attachment parts 12 provided in the longitudinal direction of the rocker molding 1, the elongated holes 13 and 14 near the longitudinal center of the rocker molding 1 are simply clip-inserted holes (not shown). And it is sufficient.

As described above, the mounting structure of the rocker mall of the present invention has a vertical cross section that extends downwardly from the outermost end in the vehicle width direction of the rocker part and extends downward while slightly bulging outward, and from the lower edge of the vertical wall. Since it has a bottom wall portion extending inward in the vehicle width direction and reaching the lower surface of the rocker portion, and is solid as a whole, the guarding effect of the vertical wall and the bottom wall is outstanding. Further, in this rocker molding, the retainer attached to the back surface and the outer plate of the rocker part are fixed with screws, so that the attached state is strong, reliable, and stable. Furthermore, the work hole for inserting the tool for turning the screw into the back side of the Rotsuka Mall is provided in the bottom wall, which is difficult to see from the outside, so the work hole may spoil the appearance of the Rotsuka Mall and, by extension, the appearance of the car. I've never been there.

It goes without saying that the scope of the present invention is not limited to the embodiments shown in the drawings.

In the illustrated example, the retainer is attached so that it can have some play in the longitudinal direction with respect to the back surface of the locking molding, so as to absorb the difference in thermal deformation rate between the locking part and the locking molding, but this point is an essential requirement of the present invention. isn't it. Therefore, the scope of the present invention also includes a retainer molded into a rotcamole.
