Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an end treatment structure for a molding that is attached to the waist line of an automobile door, for example.

Generally, in the case of automobile doors, as shown in Fig. 1, a molding A formed from a stainless steel plate or the like is attached along the waist line of a door outer panel B, and the door glass of this molding A is As shown in FIG. 2, a door glass weather strip C is attached to the side of the door to prevent rainwater and dust from entering the inside of the door and to prevent the door glass from vibrating when the door is opened and closed. Further, a band-shaped cushioning material D having a U-shaped cross section is attached to the door outer panel side of the molding A to protect the painted surface that comes into contact with it. Moreover, end caps E are attached to both longitudinal ends of the molding A for the sake of appearance and to protect passengers when getting on and off the vehicle.

By the way, conventionally, the cushioning material D and the end cap E
Since these are made separately and are attached butt to each other, not only does the installation work become troublesome due to individual errors in manufacturing the cushioning material D and the end cap.
After installation, a gap F may remain at the abutted portion due to deformation over time such as shrinkage of the cushioning material D, which is unsightly. Moreover, the cushioning material D and the end cap E often come apart due to the accumulation and intrusion of rainwater and dust through the gap F.

In order to solve the above-mentioned conventional drawbacks, the present invention covers the end of the cushioning material with the end cap, which improves not only the safety of the end of the molding but also the area where the cushioning material and the end cap meet. To provide a molding terminal structure that can prevent the occurrence of gaps.

Hereinafter, details of an embodiment of the terminal structure of the molding according to the present invention will be explained with reference to FIGS. 3 to 6. Although this embodiment exemplifies a molding attached to the waist line of an automobile door outside panel, the present invention is not limited thereto and can be applied to other moldings.

Fig. 3 is a perspective view of the molding 1 with the door glass weather strip omitted, and the molding 1 is made of a metal plate and adapts to the waist line of the door outer panel in the same way as conventional moldings. It has an elongated shape, and a notch is partially formed along the longitudinal direction to prevent interference with the body panel at the longitudinal end. A string-shaped cushioning material 2 having a U-shaped cross section is attached to one of the opposing longitudinal edges of the molding 1, that is, the longitudinal edge in the width direction that comes into contact with the painted surface of the door outer panel. This cushioning material 2 is made of a relatively soft synthetic resin, and the length of the cushioning material 2 is approximately the same as or slightly shorter than the longitudinal width of the molding 1. Also,
A door glass weather strip (not shown) is disposed on the other longitudinal edge of the molding 1.

On the other hand, according to the present invention, end caps 3 are attached to both longitudinal ends of the molding 1, respectively. This end cap 3 is made of synthetic resin, and includes a narrow front wall 4 arranged along the terminal front side of the molding 1, and a wide back wall 5 arranged along the terminal back side of the molding 1. and a covering part 5a that sandwiches and covers a notch edge formed along the longitudinal direction from both the inner and outer sides, and the end of the molding 1 is sealed between the front wall 4 and the back wall 5. A mounting recess 6 is provided. The thickness T of the back wall 5 is approximately equal to the thickness t of the back surface of the cushioning material 2 disposed on the back side of the molding 1, as shown in the fourth figure.

Further, the end cap 3 is integrally provided with a cover-shaped mounting recess 7 that communicates with the mounting recess 6, and the end of the cushioning material 2 is sealed in the mounting recess 7 as shown in FIGS. 4 and 5. be done. A thin tongue piece 9 is integrally formed between the back end of the narrow peripheral wall 8 constituting the mounting recess 7 and the back wall 5, and this tongue piece 9 is attached to the back side of the cushioning material 2. Because it is polymerized, the buffer material 2
is sandwiched and covered by the end cap 3 from the front and back, that is, from the inside and outside sides.

On the other hand, a taper 10 is formed on the end surface of the front wall 4 of the end cap 3 where the door glass weather strips are overlapped, and this taper 10 slopes gently downward from the base of the front wall 4 toward the tip. The taper 10 is smoothly continuous from the general surface of the molding 1 due to this downward slope. Therefore, as shown in FIG. 6, when the door glass weather strip C is superimposed on the end cap 3, the door glass weather strip C is tightly bonded to the end cap 3 and the molding 1. be done.

With the above configuration, the cushioning material 2 is prepared, the cushioning material 2 attached to the molding 1 is placed in a molding die, and a synthetic resin compatible with the cushioning material 2 is injected into the end. Since the cap 3 is injection molded, the ends of the molding 1 and the cushioning material 2 fit into the mounting recess 6 of the end cap 3,
7, the cushioning material 2
Since the end cap 3 and the end cap 3 are completely welded and integrated, it is possible to prevent the cushioning material 2 from shrinking. As a result, the gap between the cushioning material 2 and the end cap 3 due to deformation over time is not generated as in the conventional case. Further, when the molding 1 is attached to the door outer panel, the tongue piece 9 is held between the door outer panel and the cushioning material 2, so that the attachment of the end cap 3 is permanent, and the tongue piece 9 is held between the door outer panel and the cushioning material 2. Since it is thin, the end of the molding 1 does not bulge or warp, which would impair the appearance. Furthermore, according to the embodiment, the meeting portion of the door glass weather strip C and the end cap 3 is covered smoothly by the taper 10 without any gaps.
The occurrence of a gap G due to the overlap between the conventional end cap E and the door glass weather strip C as shown in the second figure is prevented. Therefore, the door glass weather strip C is prevented from peeling off, and the appearance of the meeting area can be further improved.

As explained above, according to the terminal structure of the molding of the present invention, the terminal structure of the molding is made of a synthetic resin that is compatible with the cushioning material, is welded and integrally formed with the cushioning material, and the terminal of the cushioning material and the molding are formed integrally with the cushioning material. It also has an end cap that clamps and covers the notch edge of the molding formed along the longitudinal direction of the molding from the inside and outside sides, so it can completely prevent the cushioning material from peeling off and the notch edge will not be exposed. This eliminates the sense of danger, prevents the notch edge from hitting the body panel and damaging the paint film, improves the appearance and protects passengers when getting on and off, and the end cap is compatible with cushioning materials. Since the end of the cushioning material is made of a synthetic resin having a 100% polyester resin, the ends of the cushioning material are firmly fixed to and covered with the end cap, eliminating inconvenient gaps in the meeting area, preventing the accumulation and intrusion of rainwater and dust, and preventing molding from building up. The cushioning material and end cap can be firmly attached for a long period of time. Moreover, since the troublesome installation work caused by individual errors in the conventional method can be eliminated, there are practical effects such as the ability to carry out healthy mass production.
