Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealing structure for an opening in a vehicle body such as an automobile, which uses a highly water-absorbing string to guide rainwater to the outside of the vehicle.

In a weather strip structure that fits into an opening in a vehicle body and is joined to a closing member such as a window glass or door, conventionally, a sealing material is filled in to prevent rainwater from entering the fitting or joining part of the weather strip. Ta.

That is, as shown in the example of FIG. 2, the vehicle body 1 is made up of an outer panel 2 and an inner panel 3, and the mounting recess 4a of the weather strip 4 is fitted into the mating portion 1a of the outer panel 2 and the inner panel 3, and the weather strip 4 is fitted therein.

Further, a window glass 5 is inserted into and joined to another four mounting portions 4b of the weather strip 4.

And the end 4c of the weather strip 4 and the outer panel 2
A sealing material 6 is filled and sealed on the contact surfaces between the four mounting parts 4b and the window glass 5.

However, there are disadvantages in that filling the sealing material 6 is troublesome and that the sealing material 6 leaks from the mouth of the abutting surface, requiring an extra man-hour to remove it.

In addition, there are other conventional structures in which rainwater that has entered the fitting or joint portion of the weatherstrip is drained downward from the vehicle body by providing drainage holes or guide grooves. In order to do this, new parts were added and related parts underwent considerable processing, making the structure unavoidably complicated.

In contrast, the present invention has a structure in which a highly water-absorbent string is held between the fitting part or the joint part of the weather strip, and the rainwater that has entered is soaked in the string and is guided out of the vehicle and drained. It has a simple structure in that it is only necessary to provide a space for the string to pass through.

3 and 4 show an embodiment of the present invention, in which the vehicle body 1 is made up of an outer panel 2 and an inner panel 3 as in the conventional example, and the four mounting parts 4a of the weather strip 4 are fitted into the mating part 1a of the outer panel 2 and the inner panel 3. has been done.

Further, a window glass 5 is inserted into another mounting recess 4b of the weather strip 4 and joined thereto.

In the present invention, these abutting surfaces are not filled with a sealing material, and strings 8 with good water absorption are held in the gap 7 between the weatherstrip 4 and the outer panel 2, and the weatherstrip 4
It is supported by the lip 4d.

Further, a string 10 is held in the gap 9 between the mounting recess 4b of the weatherstrip 4 and the window glass 5, and is supported by the lip 4e of the weatherstrip 4.

As shown in FIG. 4, the strings 8 and 10 incorporated in the weather strip 4 extend from the upper edge 5a of the vehicle body opening into which the window glass 5 fits, around the both side edges 5b, and pass through the lower edge 5c to the drain outlet. Each part is made up of one continuous piece up to .

The above is an example of the weatherst IJ knob 4 to which the window glass 5 is attached, but this can also be constructed by attaching a closing member such as a door to the opening of the vehicle body.

FIG. 5 shows an embodiment of the present invention, in which the center pillar 11 is composed of a center pillar outer panel 12 and a center pillar inner panel 13, and a mounting recess 14a of a weather strip 14 is fitted into a mating portion 11a of the center pillar outer panel 12 and a center pillar inner panel 13.

A string 16 with good water absorption is held in the gap 15 of the fitting portion.

On the other hand, the door 11 is made up of a door outer panel 18 and a door inner panel 19, and has a weather strip 14.
A joint surface 14b of the door inner panel 19 contacts the door inner panel 19 to form a door stop.

Attachment groove 1 continuous to joint surface 14b along this doorstop part
4c is recessed, and a string 20 with good water absorption is held in the mounting groove 14c.

As described above, the present invention is constructed so that a string with good water absorption is held in the fitting part or joint part of the IJ knob (weather) provided between the vehicle body opening and the closing member.
Rainwater that has entered the fitting or joint is absorbed by this water-absorbing string, and due to the capillary action of the string, it is sent to the drain without stagnation and drained out of the vehicle.

Therefore, unlike conventional methods, there is no need to fill in sealant and spend extra man-hours, or to install a complicated drainage system. Instead, all you need to do is pass a water-absorbing string through the gap. It gets easier.

Moreover, by passing this string through, the drainage work can be carried out reliably, so the effect is truly great.
