Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative molding and a method for manufacturing the same.

[0002]

2. Description of the Related Art As a conventional technique of this kind, Japanese Patent Laid-Open No.
The one disclosed in Japanese Patent No. 234859 is known. The decorative molding disclosed in this publication includes a metal strip bent into a predetermined shape, an adhesive layer formed on the design surface of the metal strip, a decorative film excellent in flexibility formed on the adhesive layer, and a metal. An elastic lip formed on the adhesive layer located at the edge of the strip. The decorative film is a colored resin film,
It has an adhesive layer formed on the surface of the colored resin film and a transparent resin layer formed on the surface of the adhesive layer.

On the other hand, in the method of manufacturing a decorative molding disclosed in the above publication, an adhesive applying step of applying an adhesive to the design surface of a metal strip and a metal coating on the back surface of the decorative film (that is, the back surface of the colored resin film). A step of adhering a decorative film to the adhesive-coated surface of the strip, a step of bending a metal strip having the decorative film into a predetermined irregular cross section together with the decorative film, and an elastic seal member at the edge of the bent metal strip. And an extrusion molding step of forming by extrusion molding.

[0004]

However, in the above-mentioned decorative molding, since the decorative film is formed by laminating the three layers of the colored resin film, the adhesive layer and the transparent resin layer, the thickness of the decorative film increases. However, there is a possibility that the flexibility may be deteriorated and the flexure may be broken.

On the other hand, in the above-described method of manufacturing a decorative molding, there is an adhesive applying step of applying an adhesive to the design surface of the metal strip, and therefore the number of manufacturing steps increases accordingly.

Therefore, the invention of claim 1 has as its technical problem the thinning of the portion acting as a decorative film to secure the flexibility.

A second aspect of the present invention has a technical object to eliminate the adhesive applying step of applying an adhesive to the design surface of the metal strip.

[0008]

[Means for Solving the Problems] 1 The technical means (hereinafter referred to as the first technical means) taken in the invention of claim 1 in order to solve the above technical problems is formed by bending into a predetermined shape. A metal strip, a decorative film having excellent flexibility adhered to the design surface of the metal strip, and an elastic seal member formed on the edge of the metal strip, the decorative film, a transparent resin layer, and a transparent resin layer The colored layer is printed on the back surface and faces the design surface of the metal strip.

According to the first technical means, since the decorative film is composed of the two layers of the transparent resin layer and the colored layer printed on the back surface thereof, the adhesive layer between the two is unnecessary. , Its thickness is reduced, and flexibility can be secured. As a result, it is possible to avoid breaking the decorative film as much as possible when the metal strip with the decorative film is formed by bending.

In order to solve the above technical problem, a second aspect is provided.
The technical means taken in the invention (hereinafter referred to as the second technical means) is a decorative film fixing step for fixing a decorative film on a metal strip via the adhesive layer, using a decorative film having an adhesive layer on one surface. And a decorative molding is manufactured by a bending forming step of bending and forming a metal strip having a decorative film together with the decorative film and an extrusion forming step of forming an elastic seal member by extrusion forming on the bent and formed metal strip. .

According to the second technical means, since the decorative film having the adhesive layer on one surface is used and the decorative film is formed on the metal strip via the adhesive layer, the adhesive is applied on the metal strip. It is possible to omit the adhesive coating step, which can reduce the number of manufacturing steps.
