Description

  The present invention relates to a molding in which a decorative strip is disposed in a concave groove on the surface of a molding body, and the tip of the decorative strip is covered with the molding surface.

  For example, in a side molding that is attached to the side of the body of an automobile, a concave groove that is shorter than the molding body along the longitudinal direction of the molding body is formed on the surface of the molding body that is a long molded product in order to enhance decoration. And a decorative strip made of an extruded product having a metal surface or the like is disposed in the concave groove.

  In addition, the side molding has an outer shape of the front end portion 52 of the molding body 51 on one side as shown in FIG. 4 for the purpose of enhancing the sense of unity with the automobile body when attached to the automobile body. There may be a tapered shape that becomes narrower from the side part 53 to the side part 54 on the other side.

  However, since the decorative strip is obtained by cutting a long extruded product into a predetermined length, if it is arranged in the groove on the surface of the molding body as it is, the outer shape of the tip of the molding body is There is a problem that the outer shape of the tip of the decorative strip is different, and the sense of unity and unity between the molding body and the decorative strip is impaired.

  Therefore, as in the conventional example shown in FIGS. 4 to 7, with respect to the concave groove 57 on the surface of the molding body 51, the shape of the tip portion 58 is made to match the outer shape of the tip portion 52 of the molding body 51. A decorative strip insertion hole 64 that communicates with the front surface side 55 of the molding body 51 in front of the distal end of the concave groove 57 is formed at the distal end of the groove 57, and the distal end portion of the decorative strip 65 extends from the decorative strip insertion hole 64. It has been proposed that the tip 66 of the decorative strip 65 is covered with the surface of the molding body 51 by inserting 66 and placing it on the back side 55 of the molding body.

However, as described above, in the molding that inserts the tip 66 of the decorative strip from the decorative strip insertion hole 64 at the tip of the concave groove 57 and arranges it on the front surface side 55 of the molding main body, Since the wall portion (one side wall in the illustrated example) of the concave groove 57 does not exist in front of the insertion hole 64, the front end portion 66 of the decorative strip inserted from the decorative strip insertion hole 64 is the concave groove 57. As shown by a chain line in FIG. 5, the decorative strip 65 is lifted from the concave groove 57 in the vicinity of the tip of the concave groove 57. The aesthetics may be impaired. Even when the decorative strip 65 is bonded to the bottom wall 58 of the concave groove 57 with an adhesive tape or the like, if the tip 66 of the decorative strip is deformed or tilted on the front side 55 of the molding body, Adhesiveness between the decorative strip 65 and the concave groove 57 is impaired near the tip of the concave groove 57, and the decorative strip 65 is lifted from the bottom wall 58 of the concave groove 57, which may impair the aesthetics of the molding.
