Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a molding that is attached to the exterior of an automobile for protection and decoration.

The corner molding will be explained below, but of course it is not limited to this.

<Prior art> Recently, from the viewpoint of enhancing the design effect, side moldings 1 and corner moldings 2, which have a decorative layer with metallic luster formed on their surfaces, have come to be installed around the sides of the vehicle body (first figure).

<Problems to be solved by the invention> However, in general, the side molding 1 is made of a soft synthetic resin material such as soft polyvinyl chloride with a decorative layer 1a such as glossy aluminum foil, from the viewpoint of protecting the vehicle body and ease of formation. It was placed on the surface and formed by integral extrusion. In addition, the corner molding 2 has a bent part A in the longitudinal direction to maintain the shape when the interior is stripped to reduce weight, and to secure bolts etc. for mounting the vehicle body, and has a bent part A in the longitudinal direction, so that the cross-sectional shape changes. Because of the fact that extrusion molding is not possible, the molding body 2b
is injection molded from a hard synthetic resin material such as ABS, the surface is plated to form a decorative layer 2a with metallic luster, and cushioning material 3 is interposed on both ends of the molding body 2b to form a car body corner 4, etc. (Figures 2 and 3). In addition, when corner molding 2 is integrally molded by injection molding with glossy aluminum foil on the surface, wrinkles may appear in the glossy aluminum foil or the glossy aluminum foil may peel off when the temperature returns to room temperature after molding. Therefore, decorative layers with metallic luster are usually formed by plating.

Therefore, the side molding 1 and the corner molding 2 have different treatments for the decorative layers 1a and 2a, respectively, and have different metallic luster, which may impair their aesthetic appearance.
In addition, the plating process itself required many man-hours for manufacturing, resulting in high costs.

This invention solves the above-mentioned problems, and provides a molding whose main body is injection molded from a synthetic resin material and has a decorative layer, which can reduce manufacturing man-hours and is inexpensive, and which can also be used as a corner molding. In such a case, the decorative layer of the corner molding can be formed in the same manner as the side molding, and the object is to provide a molding that enhances the design effect without impairing the aesthetic appearance.

<Means for solving the problem> The gist of this invention is to have a molding body formed by injection molding from a hard synthetic resin material, and a molding body formed by integral extrusion molding from a soft synthetic resin material with a decorative layer on the surface. A molding that is composed of two types of members: a decorative part that fits into the side end of the molding body, and is arranged with the back side of the decorative part in contact with the member to be attached, the side end of the molding body A hook-shaped protrusion with a concave groove that opens toward the outer surface of the molding body is formed on the part, and a decorative part extends from the bottom to cover the outer surface of the hook-shaped protrusion and the bottom that comes into contact with the member to be attached. and a convex portion fitted into a concave groove at the tip of the extending portion, and a decorative layer is provided on the outer surface of the extending portion.

<Example> Hereinafter, an example of this invention will be described based on illustrated examples.

In FIG. 4, an example is shown as a corner molding 12,
A sectional view thereof is shown.

The molding body 20 is made of a hard synthetic resin material such as ABS or polypropylene.
It is injection molded to correspond to the shape of. Hook-shaped protrusions 21 having concave grooves 21a opening toward the outer surface of the molding body 20 are formed at both end portions shown in the upper and lower portions of FIG. Further, on the back surface of the molding body 20, an appropriate number of mounting portions 20a having bolt embedding holes 20b are formed in a protruding manner so that the molding body 20 can be mounted to the vehicle body corner 4. Then, the bolt 5 is embedded in the bolt embedding hole 20b of the mounting part, and the bolt 5 is inserted into the bolt hole 4a formed in the vehicle body corner 4, and the nut is tightened from the back side.
The corner molding 12 with which the parts 2 are fitted is attached to the corner 4 of the vehicle body.

The decorative portions 22 fitted to both end portions of the molding body 20 are formed by extrusion molding from a soft synthetic resin material such as soft polyvinyl chloride. The decorative portion 22 includes a bottom portion 22a that comes into contact with the vehicle body corner 4 after the corner molding 20 is attached to the vehicle body corner 4, and an extension that extends from the bottom portion 22a and covers the outer surface side of the hook-shaped projection 21 of the molding main body. Installation part 2
2b, and a convex portion 22c formed at the tip of the extending portion 22b and fitted into the concave groove 21a of the hook-shaped projection 21, and has a cross-sectional shape that can be fitted into the hook-shaped projection 21 of the molding main body. Furthermore, the extension portion 22 of the decorative portion
A decorative layer 23 having metallic luster, such as aluminum glossy foil, which corresponds to the decorative layer of the side molding and which is integrally extruded during the extrusion molding of the decorative portion 22, is disposed on the outer surface b. By the way, this decorative layer 23 is
In order to further improve the design effect, a different colored foil may be used as appropriate, or a synthetic resin material of a different color from the decorative portion 22 may be used.

The fitting operation of the decorative part 22 to the molding main body 20 is carried out by moving the decorative part 22 in the longitudinal direction of the molding main body 20 from the end surface of the molding main body 20 in the longitudinal direction while fitting the decorative part 22 into the hook-shaped protrusion 21 to a predetermined position. The space between the bottom part 22a and the convex part 22c of the decorative part 22 is widened at a predetermined position of the molding main body 20 without placing or moving the molding main body 20 in the longitudinal direction, and the hook-shaped protrusion 21 is fitted between them. Let's do it. At this time, since the decorative portion 22 is made of a soft synthetic resin material, it follows the shape of the molding body 20 in the longitudinal direction without any trouble, and can be easily and reliably attached.

Therefore, in the corner molding 12 of the embodiment, there is no need to form the decorative layer 23 by plating, and if the decorative portion 22 provided with the decorative layer 23 is fitted into the hook-shaped protrusion 21 of the molding main body 20, , the corner molding 12 provided with the predetermined decorative layer 23 can be easily manufactured. Therefore, the molding body 20 is formed by injection molding and the molding 12 has the decorative layer 23.
In this case, the number of manufacturing steps can be reduced and the cost can be reduced. Moreover, since the decorative layer 23 is formed in the same manner as the decorative layer of the third molding, the aesthetic appearance is not impaired.

Furthermore, in the corner molding 12 of the embodiment, when a force is applied to the molding main body 20 after it is attached to the vehicle body corner 4, such as shaking upward in FIG.
comes into contact with the vehicle body corner 4, and the extension portion 22b extending from the bottom portion 22a contacts the hook-shaped projection 2 at the side end of the molding body.
1 Covering the outer surface, a convex portion 22c at the tip of the extended portion 22b
is fitted into the concave groove 21a of the hook-shaped projection 21, so that the protrusion 2
2c, the extended portion 22b, the intersection portion B between the extended portion 22b and the bottom portion 22a, etc., attempt to rotate in the counterclockwise X direction. However, since the entire back surface of the bottom portion 22a is in contact with the vehicle body corner 4, rotation of the intersection portion B between the extension portion 22b and the bottom portion 22a is restricted, and therefore the extension portion 22b and the convex portion 22c
The rotation of the molding body 20 is also restricted, and the upward movement of the molding body 20 is restricted. And, of course, the lower decorative part 2
2 has a similar configuration, so the molding body 20
The downward deviation of is also regulated.

Therefore, in the corner molding 12 of the embodiment, even if the portion of the molding 12 that contacts the vehicle body corner 4 is the decorative portion 22 made of a soft synthetic resin material, the vertical vibration of the molding 12 can be controlled and a stable state can be maintained. The molding 12 can be attached to the corner 4 of the vehicle body.

Of course, in the corner molding 12 of the embodiment, since the decorative portion 22 made of a soft synthetic resin material is in contact with the outer surface of the vehicle body corner 4, it also functions as a cushioning material.

Note that, for reasons of design, the decorative portion 20 having the decorative layer 23 may be fitted only to one end of the molding main body 20.

<Operations and effects of the invention> In the molding according to this invention, a soft synthetic resin material having a decorative layer on the outer surface of the extending portion is used for the hook-shaped protrusion at the side end of the molding body formed by injection molding from a hard synthetic resin material. Since the decorative part is integrally extruded from a resin material and is integrated,
Even if the main body is formed by injection molding, a molding having a predetermined decorative layer can be manufactured without plating, and manufacturing man-hours and costs can be reduced. Furthermore, when used as a corner molding, since the decorative layers of the side molding and the corner molding can be formed in the same manner, an effect that does not impair the aesthetic appearance can be achieved.

Furthermore, since the decorative portion is made of a soft synthetic resin material, it can be easily and reliably attached to the molding body.

Furthermore, in the molding according to this invention, after it is attached to a member to be attached such as a car body, the molding body shakes and each part of the convex part and extension part rotates except for the bottom of the decorative part that is in contact with the car body. Even if you try to move the protrusion or extension, the bottom part that is connected to the protrusion or extension part is in contact with the attached member, so the rotation of the intersection between the bottom part and the extension part is restricted, and the protrusion or extension part Rotation of the part is restricted. Therefore, in the molding according to this invention, even if the part that comes into contact with the attached member is a decorative part made of a soft synthetic resin material, the vibration of the molding can be controlled.
It can be stably attached to the part to be attached.
