[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening seal structure for a door provided at a rear opening of a vehicle.

[0002]

2. Description of the Related Art FIG. 1 is a perspective view showing the outline of a vehicle embodying the present invention. . The first door 20 is a door having a large width, and is supported via a hinge 22 on the vehicle body side on the left side of the door opening 10 (when the vehicle body is viewed from the rear). The first door 20 supports the spare tire 15 and the like. The second door 40 is a door whose width dimension is smaller than that of the first door 20,
2 and is supported by the vehicle body on the right side of the door opening 10. Therefore, the first door 20 and the second door 40
It has a so-called double door structure. An opening seal that guarantees opening and closing of the door and that has a sealing function when the door is closed is provided at the overlapping portion of the first door 20 and the second door 40 of the double door structure.

FIG. 3 shows a conventional opening seal structure corresponding to the section BB of FIG.
The glass 26 is fixed to the window of the frame 24 via a resin molding 28. The glass 48 is fixed to the window of the frame 44 of the second door 40 via the resin molding 50. An opening seal that covers a gap G that is an opening required for opening and closing the door is provided at a joint between the frame 24 of the first door 20 and the frame 44 of the second door 40. Conventional opening seal comprises a first weather strip 60 made of soft material, it has been adhered to a more inner side of the second frame 44 of the door 40 to the double-sided adhesive tape 62. The lip portion 61 at the tip of the first weather strip 60 was pressed against the inner surface side of the frame 24 of the first door 20 to form an opening seal. Also, the second door 40
An extension panel 46 is provided on a frame 44 of
The second weather strip 70 is provided on the extension panel 46 to improve the sealing performance and the appearance.
A first weather strip and a second weather strip of this kind
The opening seal structure with the opening
It is disclosed in Japanese Patent Application Laid-Open No. 2-185129. In another example of the related art shown in FIG.
The configuration of A was changed, and the clip 64 was fixed to the frame 44 of the second door 40 by the clip 64. The use of a screw as a means for fixing the weather strip is disclosed, for example, in Japanese Utility Model Laid-Open Publication No. Sho 60-22451.

[0004]

In the conventional opening seal structure shown in FIG. 3, when an external force is applied from the outside of the gap G, the first weatherstrip 6 is closed.
0 may be deformed inward, and the sealing property of the lip portion 61 may be impaired, and the adhesive strength of the double-sided adhesive tape may be reduced by use. In the structure shown in FIG. 4, there is a problem that the weather strip 60A is easily deformed by an external force from the outside of the gap G, and a problem that the number of parts increases due to the use of the clip. Was. Further, it was necessary to perform rust prevention treatment on the mounting holes.
Japanese Unexamined Utility Model Publication No. 60-22451 also has a problem in that the number of parts increases because screws are used. Therefore, the present invention provides an opening seal structure that solves the above-mentioned conventional problems.

[0005]

The sealing structure of the door opening according to the present invention is such that the first door and the second door are both a door frame, a glass fixed to a window of the door frame, and a peripheral edge of the glass. The part is provided with a resin molding integrally molded. The first weather strip mounting portion for covering the opening of the first door and the second door is sandwiched between the bent portion extending the edge of the frame of the first door and the resin molding. And the first door

[0006]

[Function] The first weather strip uses glass as a frame.
In the process of bonding and fixing
And use fasteners or other fasteners
It can be attached with good assembling operability without any trouble. Also,
When the first door and the second door are closed, the first weather strip attached to the first door is pressed against the outer surface of the resin molding of the second door to achieve a seal.

[0007]

FIG. 2 shows an embodiment of the present invention.
2 shows a BB section of FIG. 1. Frame 2 of first door 20
The fact that the module glass 26 is fixed to 4
This is the same as the conventional structure shown in FIG. The glass 26
It is fixed to the frame 24 of the first door 20 by an adhesive 29 together with a resin molding 30 formed integrally with the peripheral portion of the glass 26. Similarly, in the second door 40, the module glass 48 is fixed to the frame 44 of the second door 40 with the adhesive 49 together with the resin molding 52 formed integrally with the peripheral portion of the glass 48.

The first weather strip 65 fixed to the first door 20 side has a mounting portion 65A sandwiched between the bent portion 24A of the frame 24 and the resin molding 30;
A lip portion 65 </ b> B extending toward the second door 40 and covering the gap G. When the module glass 26 is bonded to the frame 24 with the adhesive 29, the mounting portion 65 </ b> A of the first weather strip 65 includes the resin molding 30 fitted on the periphery of the glass 48 and the end of the frame 24.
The edge is clamped and fixed between a bent portion 24A formed by bending the edge along the resin molding 30 . First door 20
When the second door 40 is closed, the lip portion 65B of the first weather strip 65 is pressed against the outer surface of the resin molding 52 on the second door 40 side to achieve sealing. Since the first weather strip 65 is disposed so as to seal the gap G from the outside, the first weather strip 65 has high durability against external force from outside. Furthermore, since the lip portion 65B is pressed against the surface of the resin molding 52, deterioration is less than when pressed against a metal member or glass .

The frame 44 of the second door 40 has an extension panel 47, and a second weather strip 70 is fixed to the end of the extension panel 47. The lip portion 70A of the second weather strip 70 is
Box portion 2 formed on frame 24 of first door 20
4B is pressed to achieve a seal. In the above-described embodiment, the first weather strip is attached to the first door, but may be attached to the second door. Similarly, a second weatherstrip may be attached to the first door side.

[0010]

As described above, the present invention is concerned with the opening seal structure between the first door and the second door having the double door structure, in which the glass fixed to the window of the door and the door frame are formed. It has a structure in which a weatherstrip is sandwiched between them. This mounting structure allows the glass to flex
At the same time in the process of bonding and fixing to the
Flop can be reliably attach a, a separate zipper
The assembling operability is improved without using . Sealing lip of the weather strip, to the other side of the molding of the door, it is pressed from the outside, while achieving a reliable sealing, as compared with the case where the metal member is pressed against the glass
Less deterioration. Since no fastener is used for mounting the weather strip, no rust prevention measures are required for the fastener mounting portion. Seal structure of door opening of the present invention
Is a first weatherstrip that reliably covers the outer surface;
An effect such that enhanced sealing property and appearance in association with pieces of the second weather strip that provided on the inner side of the superposed section of the door.
