Abstract

PURPOSE:To enable external appearance and productivity to be improved by sticking closely a main material having characters and others printed on its surface in advance and a decorative tape having a transparent coating layer which covers characters and others between a surface layer made of a transparent or semitransparent resin material and a back layer. CONSTITUTION:A decorative tape 13 is held between a surface layer 11 made of a transparent resin material and a back layer 12 made of a transparent or semitransparent resin material allowing them to be closely stuck as an integral unit so as to form a decorative molding. And the decorative tape 13 consists of a main material 16, on which characters, figures, and others 15 are printed in advance, a transparent coating layer 17 which covers characters, figures, and others 15, and of a reinforcement layer 18 which is sticked underneath the main material 16. As characters, figures, and others 15 on the main material 16 are covered with the coating layer 17 made of the transparent material. This configuration can prevent characters, figures, and other 15 from being peeled or getting out of shape by external causes. Accordingly, this enables external appearance and productivity to be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to decorative moldings that are mounted and fixed on the outside of an automobile body.

2. Description of the Related Art Generally, the appearance of vehicles such as passenger cars is improved by fixing elongated decorative moldings to the outside of the vehicle body, for example, to the surface of the door.

For example, the decorative molding 3.3 attached and fixed to the door 2 of the vehicle 1 shown in FIG. It is made by attaching resin, PVC, urethane resin, etc. Furthermore, when a transparent resin is used as the resin adhered to the surface of the main body, a decorative molding in which a metal layer such as aluminum foil is formed between the transparent resin and the main body by means such as vaporization in order to further improve the appearance. A structure has also been proposed.

On the other hand, in addition to the above-mentioned decorative molding, decorative letters, designs, etc. arranged in the company emblem or symbol mark, etc. are printed on the surface of the main body in advance, and a transparent coating layer covering the main body is printed on the surface of the main body. There is a demand for decorative moldings that allow the characters, designs, etc. to be visually recognized from the outside. That is, as shown in FIG. 4, a transparent resin material 6 is placed above the main body 5 on which the above-described characters 1 and designs 4 are printed in advance, and the two are tightly fixed, thereby creating the decorative molding shown in FIG. I got a 7. As the above-mentioned close fixation means, injection molding or extrusion molding means, or means for fixing simply by intervening an adhesive are used.

Problems to be Solved by the Invention However, in the conventional decorative molding structure in which the character 9 design etc. are visible, a "flow" phenomenon occurs at the edge of the character 1 design during the manufacturing process. However, there was a problem with the appearance. For example, when obtaining the decorative molding 7 by extrusion molding, the edges of the paint or pigment that depicts the characters 1 and the design 4 formed on the main body 5 may be
Character 1 design 4 □ of the finished product may collapse when it touches the mating member, or cause a "flow" phenomenon due to the resin pressure during melting, and the ``1'-1 extrusion molding progresses.''
Flow occurs at the ends of the pipe, resulting in poor appearance as described above. On the other hand, fixing means based solely on the insertion of an adhesive require a lot of labor and time, and have the disadvantage that a satisfactory finish cannot be obtained.

ζ Therefore, the present invention solves the above-mentioned drawbacks of conventional decorative moldings, especially decorative moldings in which one character design etc. is visible from the outside, and provides a material with good appearance and productivity. The purpose is to obtain decorative moldings for vehicles.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a surface layer in advance between a surface layer made of a transparent resin material and a back layer made of a transparent or translucent resin material. To provide a decorative molding for a vehicle, characterized in that the decorative molding is closely fixed to the decorative molding.

Effect With the above structure, when creating a decorative molding, the decorative tape, which has a transparent coating layer on the surface and is printed with a decorative character design, etc., is inserted between the front layer and the back layer. It is possible to create a movable molding in which the character 1 design etc. can be seen from the outside by tightly fixing them together while sandwiching them. When creating the above-mentioned decorative molding, letters are placed on the above-mentioned decorative tape.

Since the designs, etc. are pre-printed and covered with a transparent coating layer, there is no risk that the edges of the character 1 design, etc. may flow or disappear due to external factors such as contact with foreign objects or friction. In addition, even if extrusion molding is used as a close-fitting means, no "flow" will occur at the ends of the alternating current 9 patterns, etc.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the drawings. Figure 1 is an exploded view of a decorative molding structure for a vehicle according to the present invention. The film is mainly composed of thermoplastic synthetic resin films such as ionomer, polyethylene, and urethane. The back layer is made of resin, which is transparent or translucent. A decorative tape 13 is sandwiched between the surface layer 11 and the back layer 12, and the crown is tightly fixed together to complete the decorative molding 14 shown in FIG. 2.

The decorative tape 13 described above includes a main body 16 on which a character 9 design 15 is printed in advance, a transparent coating layer 17 that covers the character 0 design 15, and a reinforcing layer 18 attached below the main body 16. The main body 16 is made of a synthetic resin film such as polyester or aluminum foil.The character 0 design 14 is printed on this main body 16 using paint or pigment, and after sufficiently drying and solidifying, a transparent A covering layer 17 is deposited and formed by laminating processing means.The material of this transparent covering layer 17 is preferably the same or the same type of material as the surface IfS11, so that the covering layer 17 and the surface layer 11 can be bonded together during molding. can be thermally fused.

In order to enhance the adhesion effect with the back layer 12, the reinforcing layer 18 is made of the same transparent or semi-transparent resin material as the back layer 12 or of the same type.

When polyester is used as the main body 16, a metal such as aluminum is vapor deposited on the back side of the main body 16, and an adhesive is interposed between the vapor deposited metal and the back surface to firmly adhere and fix it. Also, when aluminum foil is used as the main body 16,
An adhesive is interposed between the main body 16, the covering layer 17, and the reinforcing layer 18 to fix them. On the other hand, if the main body 16 has appropriate thickness and rigidity and has good adhesion to the back layer 12, the reinforcing layer 18 does not necessarily have to be formed.

While extruding the transparent resin material constituting the surface layer 11 prepared as described above and the transparent or semitransparent resin material constituting the back layer 12 using two separate extruders, the boundary between the two phase resin materials is extruded. By inserting decorative tape 13 in the area,
Decorative moldings according to the invention can be made. It goes without saying that, in addition to the above-mentioned extrusion molding, injection molding means or simply fixing means using an adhesive can be used as a production means.

Effects of the Invention As explained in detail above, the present invention has a structure in which a decorative layer is preliminarily applied to the surface between the surface layer made of a transparent resin material and the back layer made of a transparent or translucent resin material. The decorative tape, which has a main body printed with the character 1 design, etc., and a transparent coating layer that extends over the character 9 design, etc., is tightly fixed in one body, so the appearance of the obtained decorative molding is extremely good. can do. In other words, characters printed on the subject.

The designs, etc. are completely covered by a transparent resin coating layer, eliminating peeling and crumbling phenomena caused by external causes.
It always has a clear display function, and this display function is not impaired in any way even if extrusion molding or other means are used. Therefore, it is possible to provide a molding for a vehicle that can withstand any manufacturing method, has a good appearance performance of the obtained product, and has excellent productivity.
