Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a waist molding for a tonneau 7 for an automobile, and particularly relates to an improvement of a waist molding for an automobile door equipped with a corner piece.

(2) Background of the Technology In general, as shown in Figure aJ1, an automobile door D consists of a door body 1 and a door sash 2, and on the outside edge of the waist opening of the door body 1, there is an outside edge of the waist opening and a door window panel 3. West molding M, which decorates a part of the cloth 1 of the door body 1 while cutting the seal between the door body 1 and the door body 1, is designated as "I".

(3) Conventional technology and its problems Conventionally, this type of waist mall and C were developed in 1988-31.
There is something shown in Publication No. 217. This is a long object formed into a constant cross section by extrusion molding or the like as shown in FIGS. 2 to 4, for example. It consists of a metal decorative part 6 which is fixed to the waist opening and covers the outer edge of the waist opening, and a rubber or resin lip part 7 which closes the waist opening between the decorative part 6 and the door window panel 3. In this case, in the case where a cope piece 8 is provided at the joint corner between the door body 1 and the front side part of the door sash 2, as shown in FIGS. 2 and 4, the above-mentioned waist molding M The front side part Ma has a notch part 9 that avoids the corner piece 8, and the front side part Ma of the waist molding M extends along the outer side of the corner piece 8 to the front end of the waist frontage flange 4.

In this type, the corner piece 8 is a member having a cross-sectional shape, for example, and the lower portions of both side walls are arc welded to the waist opening flange 4, so that the corner piece 8 is located on the front side of the waist molding M. The portion Ma cannot be fixed to the waist opening flange 4 using the clip 5. For this reason, there is a risk that the front side part Ma of the waist molding M will be lifted up and the appearance quality of the waist part of the door body 1 will be impaired. The waist molding M is fixed to the waist portion of the door outer panel DO via an adhesive tape 10 such as butyl tape or the like, or the waist molding M itself is made to have increased rigidity.

In addition, in FIGS. 1 to 4, symbols S, 3ii and 12 are door seals, 13 is an end cap attached to the front end of the front side part Ma of the west molding M and the end on the inside of the vehicle interior, and 14 and 15 are corner pieces 8. Corner piece cover attached to the outside and inside of the door window panel 3f, 16
11 is a door weather strip, 18 is a waist inner seal attached to the waist opening edge of the door inner panel D1, and 19 is a door trim.

However, with this conventional waist molding, when the front side part Ma of the waist sail M is touched with a hand when washing or waxing the car, the front side part Ma of the waist sail M is relatively Since it easily lifted up, it was insufficient to prevent the waist molding M from lifting up.

Therefore, in order to reliably prevent such problems, it has been proposed to provide a locking piece on the front side Ma of the waist molding M and to fix the locking piece to the corner piece 8. Since the cross-sectional shape of the waist molding M at the part where the locking piece is provided is different from the cross-sectional shape of other parts, it becomes difficult to integrally mold the waist molding M by extrusion molding. The molding of the waist molding M itself becomes troublesome.

(4) Purpose of the Invention The present invention has been made based on the above points of view, and its purpose is to reliably prevent the end of the waist molding from lifting up without making the molding of the waist molding so troublesome. An object of the present invention is to provide a waist molding for an automobile door that can be used in a car door.

(5) Structure of the Invention The basic structure of the present invention is that the waist molding is formed separately before and after the rear end position of the corner piece, and a locking part that is locked to the corner piece is formed on the front side molding. , a holding part is formed at the rear end of the front side molding to hold and hold the front end of the relay side molding.

(6) Embodiments of the invention Hereinafter, the present invention will be described in detail with reference to embodiments shown in the accompanying drawings.

Although not shown in FIG. 5, in the embodiment, the J3-C, U-Stomall M is divided into a front-side molding M and a V-side molding M at the rear end of the nervy 8.

The above-mentioned front side molding M is integrally molded by zinc die-casting or the like and covers the waist part of the door outer panel DO located on the outside of the outer corner piece cover 14 and the upper front end of the door outer panel DO. A corner piece 8 is attached to the indoor side end of the front 1 in the front-rear direction to approximately medium heat.
A locking piece 20 that comes into contact with the corner piece 8 is provided in a protruding manner.

A corner piece 8 is located adjacent to the locking piece 20.
A protruding piece 22 is formed that comes into contact with the. and again,
An overlapping piece 23 that extends rearward and overlaps the front end of the rear side molding Mr is projectingly provided at the rear end of the front side molding Mf, and a holding piece 24 having an angular cross section is provided on the back surface of this overlapping piece 23. A groove portion 25 opening rearward is formed between this holding piece 24 and the overlapping piece 23. A spacer 2G molded from rubber or resin is fitted into the holding piece 24, and a holding groove 21 that holds and holds the front end of the rear molding Mr between the spacer 26 and the overlapping piece 23. On the other hand, the interior side of the spacer 26 comes into contact with the waist rising portion 28 of the door outer panel Do.

Further, the rear side molding Mr has a structure similar to a conventional waist molding structure, and has a decorative part 6 and a lip part 7.
It consists of

Furthermore, in this embodiment, the outer corner piece cover 14 has a mounting boss 29 on its back surface, and the corner piece 8 is spaced apart from the screw 3o.
It is stopped and its lower and front ends are on the front side.

Then, as shown in Figure ilO, when one end surface of the end cover is wrapped around the molding end surface J:u, when viewed from the end surface side (in the direction of the arrow X in FIG. 8), the front side molding IVB and the 17th side molding Mr. The lower edges of the two are in a straight line, creating a sense of unity.

Therefore, when attaching the waist molding M to the vehicle body, for example, the front side molding Mf is fixed to the corner piece 8 via the locking piece 20, and then the front side molding M is attached to the holding $ff27. While holding the front end of the above 17 side molding Mr, the rear side molding IVH may be fixed to the waist opening flange 4 with a clip 5 or the like.
Since the side molding Mf is fixed to the corner piece 8, even if your hand touches the front molding Mf when washing or waxing the car, the front molding Mf will not touch the front molding Mf.
A situation where f rises almost never occurs. Also, since the front end of the A2 side molding Mr is held in the holding groove 27 of the front side molding Mf, the front end of the A7 side molding Mr will lift up. There is no front side molding Mt and rear side molding Mr.
The slides are connected 1:' in the mating part, and together they decorate the waist part of the door body 1.

In addition, in this embodiment, the front side molding M (
Since the locking piece 2o and the protruding piece 22 are usually covered with the corner piece cover 14, the locking piece 20 etc. will not be exposed to the outside, and there is a risk that the appearance quality of the West Mall M will be impaired. There is no such thing.

Furthermore, in this embodiment, C has the front side molding M1 and the rear side molding Mr.
The front side molding itself is also regulated by the protruding piece 22 in the vehicle width direction with respect to the vehicle body.
Due to manufacturing errors and temperature changes, the rear side
Even if the length dimension of r changes, the front end of the front side molding Mf and the A7 side molding Mf will not be pulled into the passenger compartment. There will be no situation where the holder N27 is lifted up using the joining part of both the Ml and 1vlr as a fulcrum.Furthermore, in this embodiment, in J3, the holding N27 is formed by fitting the spacer 2G to the holding piece 24. Therefore, the width d of the cavity 25 between the overlapping piece 23 and the holding piece 24 can be formed to be large to some extent.For this reason, when molding the front side molding Mf, the holding piece 24 is The situation in which the mold part for molding the piece 24 breaks is also effectively avoided.

In the above embodiment, the freon 1-side molding Mf is molded by zinc die casting, but it is not necessarily limited to this, and may be molded from resin or the like, for example. Further, in the above embodiment, the locking piece 20 is formed as a means for locking the front side molding Mf to the corner piece 8, but the locking piece 20 is not necessarily limited to this. A clip may also be formed. Furthermore, the specific structure of the holding part that holds the front end of the rear side molding Mr is not limited to that shown in the above embodiment, and may be any suitable structure as long as it can hold and hold the front end of the rear side molding Mr. You may change the design.
