Description

[Detailed description of the invention] This invention relates to a belt line molding that also serves as a clip.

Conventionally, a belt line molding (the molding provided in section A in FIG. 1) has been attached to a door panel of an automobile as shown in FIG. 2.

That is, the belt line molding M is made by molding the surface of a metal core material 1 with an elastic material 2 such as resin or rubber, and includes a visible appearance part 3, a weather strip part 5 having flocked hair 4, and leg parts 6. A clip 7 was fitted onto the leg portion 6, and the clip 7 was used to attach the door panel 8 to the door panel 8. The clip 7 has a holding part 7a that holds the leg, and the holding part 7a branches from the holding part 7a.
It consists of a clamping part 7b which clamps the door panel 8 with the door panel 8, and the clamping part 7b is inserted into a mounting hole 9 formed in the door panel 8 and fixed.

However, this method requires the clip 7 separately and requires the above-mentioned man-hours to attach it, resulting in an increase in cost.

Furthermore, recently, mainly from the viewpoint of rust prevention, clips 7 are also being made of resin, but resin-made ones have the drawback of causing deterioration over time and decreasing the clamping force.

In addition, as a conventional example of a device that can be attached without using such a clip,
Those described in Publication No. 54-40567, Japanese Utility Model Application Publication No. 54-150233, etc. are known.

However, in both of these methods, a claw piece is cut and raised at an intermediate position in the vertical direction of the molding leg, and after this is inserted into a mounting hole formed in the door panel, the above-mentioned claw piece is further inserted at a 90° angle. Because the structure is bent and fixed, there are problems with alignment between the claw piece and the mounting hole during manufacturing.
Also, there are drawbacks such as an increase in the number of steps for 90 degree bending during assembly, which complicates various processes and impedes rationalization factors.

Therefore, this invention aims to provide a belt line molding that can solve these problems.

Figure 3 shows the belt line molding M according to this invention.
4 is a cross-sectional view showing the structure of attaching the door panel 8 to the door panel 8, and FIG. 4 is a view taken in the direction of arrow B in FIG. It has the above-mentioned structure in which the visible external portion 3, weather strip portion 5, leg portion 6, etc. are formed respectively.

By the way, in this invention, the leg part 6 of the belt line molding M has a cut part 10 which is cut and bent upward from the lower edge of the leg part 6 at a predetermined interval L and with a predetermined width W. , is bent so as to have an elastic spring force, and is formed so that the door panel 8 interposed between these parts can be elastically held by the bent part 10 and the leg part 6 remaining after being bent. It is.

That is, the bent portion 10 is slightly bent inward to sandwich the door panel 8 between it and the remaining leg portion 6, and this is inserted into the mounting hole 9 to separate the remaining leg portion 6 and the bent portion 10. The door panel 8 is held between the two.

In addition, 11 in Figure 3 is a window glass,
Reference numerals 12 and 13 are an inner weather strip section and a door panel, respectively.

Since this invention has the above-mentioned configuration, the following effects can be expected.

First, since a portion of the leg portion 6 of the belt line molding M is directly formed as a bent portion 10 at a portion corresponding to the holding portion 7b of the conventional clip 7, the clip 7 as a separate member is not required. Since it does not require any man-hours to fit it in, it is possible to significantly reduce costs.
On the other hand, although it is necessary to form the cut portions 10 at appropriate locations on the leg portions 6, this formation can be easily done by press working, so the manufacturing cost is much lower than the above factors.

Furthermore, according to this invention, although it is clamped by spring force, the assembly operation is as simple as just fitting it into the door panel, so it can be mounted at the middle position in the vertical direction of the molding leg, unlike the conventional method. Compared to a structure in which a claw piece is protruded in a cut-and-raised state, the claw piece is inserted into a mounting hole formed in the door panel, and then the above-mentioned claw piece is bent 90 degrees and fixed. During the manufacturing process, there are no problems such as alignment between the claw piece and the mounting hole, and an increase in the number of steps required for 90 degree bending during assembly, and the various steps are simple. This will contribute to rationalization.

Furthermore, even in the bent portion 10 that acts as a clip, the elastic material 2 is molded on the surface of the metal core material 1 and is in contact with the door panel 8, so there is no problem in terms of rust prevention, and there is no problem with the metal core material 1. This has various excellent effects such as no noise caused by vibrations caused by contact between the two.
