Description

  The present invention is suitable, for example, for automobile rufles, has a beautiful appearance and high quality, is robust and has an anti-rust effect, has an improved life span, is small and light, and is manufactured and mounted. In addition, the present invention relates to a vehicular rule frame in which the cover can be attached firmly and firmly.

  Various types of automotive rail frames have been proposed in the past due to their functionality and design. For example, a rail body made of a synthetic resin having a modified cross section and attached to both front and rear ends of the body. Some have a cap made of synthetic resin (for example, Patent Document 1).

However, the above-mentioned rule frame is entirely made of synthetic resin, so it is easy to mold and manufacture, but has limited design and high quality of the product due to the texture of the synthetic resin exposed on the outer surface. It was difficult to expect the property, and it deteriorated by being exposed to rain and ultraviolet rays. The appearance deteriorated over time and the strength was uneasy.
In this case, as a simple solution to the above problem, a method of painting or plating a ruler can be considered. However, it is difficult to achieve high quality with no real feeling, and the appearance is poor due to their peeling. It cannot be adopted due to the problem of quality degradation.

As a solution to such a problem, a cover cap made of a synthetic resin having a substantially U-shaped cross section is fitted to both ends of the ruler and both ends thereof are connected via a snap member. There is (for example, Patent Document 2).
However, since this cover has a cover cap made of a synthetic resin, the above-described problems still remain, and the above-mentioned connecting means is uneasy about the adhesion of the cover cap.

  Therefore, as a solution to the above-mentioned problem, a metal having a substantially U-shaped cross section made of metal such as stainless steel or synthetic resin is provided on the rail portion excluding the leg portion of the synthetic resin rule frame. The two-sided adhesive tape is adhered to the inner surface of the mold, and both edges are curled to provide a folded portion, and the double-sided adhesive tape is adhered to the rail portion, and There is one in which the folded portion is engaged with the lower end portion of the rail portion and the mole is attached to the outer surface of the rail frame (for example, Patent Document 3).

  However, in this conventional one, since the folded portion is engaged and attached to the lower end portion of the rail portion, the mold becomes large and requires a large metal plate for the mall. If this is made of a metal such as stainless steel, the mold becomes expensive and large in weight, which is difficult to mount and causes an increase in weight on the roof, increasing the burden on the vehicle body. The construction and processing of the parts are complicated, and after mounting on the rail, the legs made of synthetic resin will appear on both sides of the mold, and the appearance is uncomfortable and the appearance is bad There was a problem.

To solve the above problem, a synthetic resin cap base is connected to both ends of a synthetic resin rail body with bolts and nuts, and a synthetic resin cover is engaged with the one cap base. There is one in which a cap body made of a synthetic resin is attached to the other cap base via a clamp band (for example, Patent Document 4).
However, in this conventional one, since the rail body and the covers and cap bodies at both ends are made of synthetic resin, the above-mentioned problems still remain, and the cover and the cap body are configured separately and are attached separately. Since the method is used, the number of parts is increased, and it takes time and effort to attach the parts, and there is a problem that the attachment of only the locking claws is uneasy about the adhesion of the cover.
