Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a decorative molding for automobiles, and particularly to a roof drip molding that is fitted and attached to a roof gutter portion of an automobile.

(Prior Art) In recent years, various types of moldings have been used to decorate the edges of automobiles, and among them, exterior moldings attached to roof rain channels are shown in Fig. 4. It is common to have a C-shaped cross section. This roof drip molding 30 is made by integrally pasting a metal exterior foil such as stainless steel 32 on the outer surface of a hard synthetic resin base layer 31 such as ABS resin in consideration of decorativeness, heat resistance, weather resistance, etc. The inner surface of the base layer has a fitting opening 35 so that it can be fitted and engaged with the rising portion 21 of the roof channel 20 projecting from the roof of the vehicle body.

Then, the fitting opening 35 is inserted into the roof channel 2.
The molding 30 is attached to the vehicle body by engaging with the rising portion 21 of the molding 30 and, in some cases, caulking the necessary parts as appropriate. This caused such inconvenience.

That is, the roof channel 20, which is the attachment part of the molding, is usually made of sheet metal or the like, and is fixed to the vehicle body by spot welding or the like, so that the tip 21a of the rising part of the channel 20 has a slight deviation in the longitudinal direction. It has a tendency to have distortion, that is, undulation.
Therefore, when the rising portion 21 is attached to the opening 35 of the molding 30 as shown in FIG. A twist occurs in the longitudinal direction between the molding side end 30a, which is the engaging part, and the molding outer surface 30c, which is the decorative surface, and as a result, the surface 30c of the metal exterior foil 32 on the outer surface side of the molding 30 is caused by unpleasant reflection of light rays. A rippling phenomenon occurs.

On the other hand, the rising lower end 2 of the roof channel 20
1b is slightly protruded downward and bent so as to engage the other opening edge of the molding 30, and the molding itself also has a corresponding opening edge in order to obtain a tighter elastic fit. The molding side end 30b including the edge is bent slightly inward during molding, as shown by the broken line in FIG. However, the rising lower end 21b of the roof channel often has dimensional variations and distortions similar to those described above, and after the molding is attached, the molding side end 30b changes elastically over time. This often causes a wavy phenomenon on the molding outer surface 30c, which is a design surface.

(Problems to be solved by the invention) This invention solves the above-mentioned inconveniences in fixing roof drip moldings, and in particular prevents twisting in the longitudinal direction that occurs on the outer surface of the molding. This has been proposed for the purpose of providing a roof drip molding which prevents the occurrence of undulations on the surface of the outer metal foil due to unpleasant reflection of light rays.

(Means for solving the problem) That is, in this invention, an exterior foil made of metal foil is integrally pasted on the outer surface of a synthetic resin base layer having a substantially C-shaped cross section, and a In the roof drip molding having a continuous fitting opening, the upper side end of the base layer is bent inward to connect with the base layer main body portion to form a connecting portion having a continuous hollow portion inside; The present invention relates to a roof drip molding for an automobile, characterized in that the connecting portion is an upper engaging portion constituting the fitting opening.

(Example) The details of this invention will be explained below with reference to the attached drawings.

FIG. 1 is a sectional view of a roof drip molding 10 showing an embodiment of this invention, FIG. 2 is a sectional view of a roof drip molding 10' showing another embodiment, and FIG. 3 is a roof channel 20 thereof. It is a sectional view showing a state of attachment to.

As shown in the diagram, this roof drip molding 1
0 is formed by integrally pasting an exterior foil 12 made of stainless steel foil or the like on the outer surface side of a synthetic resin base layer 11 made of ABS resin or the like and having a substantially C-shaped cross section. The sides have an opening 19 for fitting into the roof channel in the longitudinal direction.

As mentioned above, this fitting opening 19 is usually formed between one side end 10a and the other side end 10a of the molding 10.
The feature of this invention is that the upper engaging part constituting the opening 19 has a hollow part 15 continuous inside the base layer main body part. It is formed by the connecting part 13 with.

That is, the upper molding side end 10a of the molding having a substantially C-shaped cross section is connected to the base layer 11 of the side end portion.
is bent inward and connected integrally with the base layer 11 of the main body portion, and by forming the connecting portion 13, a continuous hollow portion 15 is formed in the upper part of the molding.

By forming the connecting portion 13, a continuous hollow portion 15 having a substantially triangular or oval shape as shown in the figure is formed in the upper part of the molding. Determined by bending shape etc. In order to prevent twisting or undulation occurring on the outer surface of the molding, it is preferable to form the molding into a polygonal or elliptical shape with the long side facing the surface forming the fitting portion. Further, it is desirable that the vicinity of the connecting portion 13 be configured as a slightly recessed portion 14 in consideration of fitting with the roof channel.

On the other hand, the other side end 10b of the molding 10 is
As shown in Fig. 1, it may be bent inward to form the flange 18 and then folded back outward to make it easier to get over the lower end of the roof channel when installed, but it is also possible to do the following. preferable.

That is, as shown in FIG.
A thick bulging convex portion 17 is formed near the side end 10b corresponding to
That is to say. Note that the hollow portion 16 may be formed in the bulging convex portion 17 as necessary. With this configuration, as shown in FIG. 3, the flange 18 is also given rigidity, and even if the rising dimension of the channel is uneven when fitting with the roof channel, the outer surface of the molding will not be kinked or wavy. It is possible to avoid the phenomenon from occurring.

(Operations/Effects) As described above, in this invention, the upper engaging portion constituting the opening of the molding having the longitudinal fitting opening is connected to the base layer main body having a continuous hollow portion inside. Since it is formed by the connecting part with the roof channel, the rigidity of the upper mounting part in the fitting opening is increased and improved, and there is no dimensional variation or unevenness in the rising part of the roof channel during fitting. To prevent the non-uniformity from appearing as it is on the outer surface, which is the design surface of the molding, even if there is a problem. As a result, the unpleasant waving phenomenon caused by the reflection of light rays on the surface of the metal exterior foil on the outer side of the molding is eliminated, and the molding can be mounted with excellent appearance.

In addition, the molding according to this invention can be easily and continuously molded using the same integral extrusion molding method as in the past, and an increase in weight can be avoided by forming a hollow part. This is extremely advantageous as a molding for automobiles.
