Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a structure for attaching a side molding made of synthetic resin to a vehicle body sheet metal via a clip, and in particular, to a structure for attaching a side molding made of synthetic resin to a sheet metal of a vehicle body through a clip, and in particular to a structure for attaching a side molding made of synthetic resin to a sheet metal of a vehicle body. A bag-shaped cap made of a soft polymeric material such as soft synthetic resin or soft rubber is wired between the mounting hole drilled in the vehicle body sheet metal to be inserted and to seal the mounting hole and prevent rust. The present invention relates to a mounting structure for an interposed side molding.

<Prior Art> A conventional mounting structure of this type was as shown in FIG.

A predetermined number of mounting holes 1a are drilled at predetermined positions in a vehicle body sheet metal 1, and each mounting hole 1a has a flange portion 2a that abuts the periphery of the mounting hole 1a.
and a bag portion 2b inserted into the mounting hole 1a,
A cap 2 made of a soft synthetic resin material such as saturated polyester was provided.

Further, the clip 5 used to attach the side molding 3 to the vehicle body sheet metal 1 is made of a synthetic resin material having spring elasticity such as polyacetal or nylon, and has a flange portion 5a and a flange portion 5a.
It was provided with a capital 5b protruding from a, and a locking head 5c which bulges out from the neck 5b and whose outer diameter can be elastically reduced.

The side molding 3 attached to the vehicle body sheet metal 1 is
It is made of a synthetic resin material such as ABS or PVC, and a predetermined number of holding portions 4 for holding clips 5 are formed at predetermined positions on the back surface thereof. The holding part 4 is
A space 4 inside the opening 4a is formed to be wider than the opening 4a, and the flange 5a of the clip 5 is held in the space 4b so that the capital 5b and the locking head 5c can be projected from the opening 4a. It had been. Also,
The holding part 4 is attached to the side molding 3 via the clip 5.
When attached to the car body sheet metal 1, the side molding 3 made of synthetic resin has a higher coefficient of thermal expansion than the metal car body sheet metal 1, so that the side molding 3 can thermally expand and contract with respect to the car body sheet metal 1 after installation. The clip 5, which is attached to the vehicle body sheet metal 1, can be held so as to be slightly movable in the longitudinal direction of the side molding 3 (in the direction penetrating the paper in FIG. 5).

To attach the side molding 3 to the vehicle body sheet metal 1, the cap 2 is inserted into the mounting hole 1a of the vehicle body sheet metal 1.
At the same time, insert the holding part 4 of the side molding 3.
Assemble the clip 5, then push the locking head 5c of the clip 5 into the bag portion 2b of the cap 2,
The side molding 3 was attached to the vehicle body sheet metal 1 by bringing the periphery of the opening 4a of the holding part 4 into contact with the flange part 2a of the cap 2 at the flange part 5a of the clip 5. At that time, the flange portion 2a of the cap 2
is pressed against the vehicle body sheet metal 1 by the periphery of the opening 4a in the side molding holding portion 4, so that the cap 2 provides sealing performance and rust prevention of the periphery of the mounting hole 1a.

<Problems to be Solved by the Invention> Therefore, in the conventional mounting structure, the periphery of the opening 4a of the holding portion 4 in the side molding 3 is attached to the flange portion 2a of the cap 2 inserted into the mounting hole 1a of the vehicle body sheet metal 1. The opening 4a
The peripheral edge was to be held between the clip flange portion 5a and the cap flange portion 2a.

Therefore, after installation, the side molding 3
When the clip 5 tries to expand or contract, the periphery of the opening 4a in the holding part 4 is held between the clip flange part 5a and the cap flange part 2a, and even if the holding part 4 is formed to hold the clip 5 movably. , the side molding 3 was difficult to shift with respect to the vehicle body sheet metal 1, and there was a risk that the side molding 3 would be deformed. Furthermore, in the recent side molding 3, the edge 3A
There is a tendency to reduce the distance between the side molding edge 3A and the vehicle body sheet metal 1 as much as possible, and the side molding edge 3A is brought into close contact with the vehicle body sheet metal 1, so that the peripheral edge of the opening 4a in the side molding holding part 4 is further The cap flange 2a was pressed against the cap flange 2a, and the cap flange 2a and the clip flange 5a were strongly sandwiched, so that the above-mentioned problems were likely to occur.

Furthermore, in the conventional mounting structure, the clip 5 used when attaching the side molding 3 to the vehicle body sheet metal 1 does not come into direct contact with the flange portion 2a of the cap 2, but the holding portion 4 that holds the clip 5 When the peripheral edge of the opening 4a is brought into contact with the cap flange 2a and the side molding edge 3A is brought into close contact with the vehicle body sheet metal 1,
The holding part 4 holding the clip 5 may be deformed, and the periphery of the opening 4a may come into contact with the cap flange part 2a only locally, which may reduce the sealing performance of the cap 2. .

This invention solves the above-mentioned problem. Even if the side molding is tightly attached to the vehicle body sheet metal, the side molding deforms when the side molding expands and contracts due to heat. To provide a mounting structure for a side molding that can be slid against a vehicle body sheet metal without causing a drop in sealing performance with a cap.

<Means for Solving the Problems> The side molding mounting structure according to the present invention is a structure in which a side molding made of synthetic resin is mounted to a vehicle body sheet metal via a clip, in which the clip protrudes from the flange portion and from the flange portion. The back side of the side molding has a capital of the clip and a locking head that protrudes from the opening and is wider than the opening that holds the flange portion. A holding part is formed that allows the clip to be moved a predetermined distance in the longitudinal direction of the side molding, and the locking head of the clip held in the holding part is inserted into a mounting hole drilled in the vehicle body sheet metal. The side molding is attached to the vehicle body sheet metal, and includes a flange portion disposed around the attachment hole between the clip retaining head and the vehicle body sheet metal attachment hole, and a bag portion enclosing the retaining head. In a mounting structure in which a cap made of material is interposed, the opening size of the side molding holding part is made larger than the outer diameter of the cap flange part, and when the side molding is attached to the base side of the clip capital, the side molding holding part and The above-mentioned problem is solved by forming a shoulder that abuts the cap flange so that a gap is created between the shoulder and the vehicle body sheet metal.

<Operations and effects of the invention> In the side molding mounting structure according to the present invention,
The opening size of the opening in the side molding holding part is formed larger than the outer diameter of the cap flange part,
A shoulder portion is formed on the base side of the clip capital to abut against the cap flange portion so that a gap is created between the side molding holding portion and the vehicle body sheet metal when the side molding is attached.

Therefore, when the cap is inserted into the mounting hole in the car body sheet metal and the clip is attached to the holding part of the side molding, the locking head of the clip is pushed into the bag part of the cap and the side molding is attached to the car body sheet metal. In this case, the side molding holding part does not come into contact with the cap flange part or the vehicle body sheet metal, and the periphery of the opening of the side molding holding part is not pinched between the clip flange part and the cap flange part as in the conventional case.

Therefore, even if the side molding expands and contracts due to heat, the clip is held movably in the longitudinal direction of the side molding relative to the side molding holding portion, so the side molding does not move relative to the vehicle body sheet metal. This prevents deformation. Even if the side molding is brought into close contact with the car body sheet metal, the only problem is that the clip itself is strongly compressed against the cap flange through its shoulder, and the side molding is not displaced from the car body sheet metal. As a result, deformation of the side molding can be prevented. In addition, at this time, the periphery of the opening of the side molding holding part is not pressed against the cap flange part as in the past, but there is a clip on the cap flange part to firmly attach the side molding to the vehicle body sheet metal. Since the cap is strongly pressed directly through the shoulder portion, the deformation of the holding portion does not affect the cap flange portion, and the sealing performance of the cap does not deteriorate.

<Example> Hereinafter, an explanation will be given based on drawings showing an example of the present invention.

In the mounting structure of the embodiment shown in FIGS. 1 to 3, a predetermined number of mounting holes 11a are bored at predetermined positions in the vehicle body sheet metal 11, as in the conventional case, and each mounting hole 11a

The sides in the longitudinal direction are opened as insertion ports 14c for attaching the clip 15, and the internal space 14b has a box shape with a width and thickness corresponding to the flange 15a of the clip 15. A substantially circular opening 14a whose inner diameter R3 is larger than the outer diameter R2 of the cap flange portion 12a is formed on the upper surface of the back side of the side molding 13 as shown in FIG.
When the flange portion 15a of the clip 15 is inserted into the opening 14a from the insertion port 14c on the side of the holding portion 14, the capital 15b and shoulder portion 1 of the clip 15 are inserted into the opening 14a.
Guide part 1 that opens so that 5d does not get in the way
4d is formed. Further, on the back side of the side molding 13 in the holding part 14, there is a rib 14e that supports the clip flange part 15a when the clip 15 is held in the holding part 14 and the clip neck part 15b etc. are protruded from the opening part 14a. A protrusion 14f is formed that restricts the crib flange portion 15a to be movable by a predetermined distance in the longitudinal direction of the side molding 13.
