Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water draining structure for a weather strip support for an opening/closing body such as a door or a trunk lid.

As shown in FIG. 1a, for example, a trunk lid 2, which is an opening/closing body of an automobile, etc., seals between the trunk lid 2 and the inner edge of a trunk opening 4 opened in a vehicle body panel 3, as shown in detail in FIG. 1b. In addition, a weather strip 6 is fitted and secured to a flange 5' forming the inner edge of the trunk opening 4 of the vehicle body panel 5.

However, since the flange 5' is relatively thin, it may become wavy during processing, or there may be a gap between the flange 5' and the U-shaped support part 6a of the weather strip 6 that is simply fitted due to a step in the panel fitting part. A slight gap was created, and as a result, rainwater, car wash water, etc., entered the space 6b surrounded by the support section 6a, and even entered the trunk.

In order to solve this problem, conventionally, as shown in FIGS. 2a and 2b, a drainage notch 7 has been provided on the outside of the support part 6a at the lower side of the opening 4 of the weather strip 6. There are things, but
This method not only increases costs because the notch 7 is formed in a separate process after the weather strip 6 is extruded, but also requires care when attaching the weather strip 6 to the flange 5' as the notch 7 is weak. There was a drawback that this part would break or break if not worked on.

In view of the above-mentioned drawbacks, the present invention provides a water drainage structure for an opening/closing body in which an inverted trapezoidal drainage recess with an inclined side wall is formed in the vehicle body panel without requiring any special processing on the weather strip. .

A first embodiment of the present invention will be described below with reference to FIGS. 3a and 3b. Note that parts that are the same as those in the prior art are given the same reference numerals and their explanations will be omitted.

In the present invention, the U-shaped support portion 6a of the weather strip 6 is fixed to the flange 5' provided on the vehicle body panel 5 as in the conventional manner, and the U-shaped support portion 6a of the weather strip 6 is attached to the vehicle body panel 5. Support part 6a
When molding the vehicle body panel 5, a groove 8 for draining water is formed, which extends from the end surface 9 of the flange 5' to a position below the area where the lip 6c of the weather strip 6 contacts. Form by doing.

As shown in FIG. 3A, the groove has an inverted trapezoidal cross section, that is, the side wall thereof is inclined so that the width of the groove on the bottom wall side becomes gradually smaller than the opening.

With this configuration, the present invention allows water that has entered the support portion 6a of the weather strip 6 to be removed by the draining groove 8.
will be distributed and discharged outside the vehicle.

Furthermore, since the side wall of the groove 8 is an inclined surface as described above, the seal lip within the U-shaped support portion 6a of the weather strip 6 is discontinuous on the outside of the flange vehicle, but inside the flange vehicle interior. On the outside, it continues from the inclined side wall surface to the bottom wall surface, so high-pressure water flows back when washing a car etc. and causes the U-shaped support part 6a
Even if it enters the space, there is no need to worry about it entering the vehicle interior. As soon as the pressure of the water entering from the groove decreases, the water within this U-shaped support portion 6a is discharged to the outside of the vehicle from between the outer surface of the flange vehicle and the seal lip.

4a and b, the end portion of the groove 8 located in the space 6b is prevented from coming out into the edge 9 of the flange 5', that is, the groove of the flange 5' in the embodiment of FIG. A second embodiment of the present invention is shown in which the portion corresponding to the edge of flange 5 is formed flush with the general surface. Since the edge of ' is straight, it is easy to fit the weather strip 6.
This has the advantage of making installation work much easier.

As described above, according to the water draining structure of the present invention, water in the space formed by the support part of the weather strip and the flange of the car body panel can be reliably drained through the groove formed at the same time when the car body panel is molded. At the same time, there is no fear that the water sent into the space from this groove will intrude into the vehicle interior. Furthermore, since no cutout is formed in the weather strip, the installation work is facilitated, and since no cutout work is required, costs can be significantly reduced.
