Description

[Detailed description of the invention] <Industrial application field> This invention uses a rear fender and a trunk side panel to connect the water drain hole provided in the trunk side panel to the recess formed at the side bottom of the automobile trunk. This invention relates to a water drain plug made of an elastic polymer that is attached.

<Prior art> In the trunk room of an automobile as shown in FIG. 6, as shown in FIG.
A recess 5 is formed at the bottom of the trunk side by the trunk side panel 3 and the trunk side panel 3. After a long period of time, rainwater L that has entered from the outside may accumulate in the recess 5, which may promote rusting of the rear fender 1 and the like.

For this reason, as shown in the figure, a drain hole 7 is provided on the side of the trunk side panel 3, and a drain plug 9 made of an elastic polymer that can be forcibly attached and detached is attached to the drain hole 7. The drain plug 9 was removed periodically to drain the stored rainwater. A known publication describing something similar to this water drain plug is, for example, Japanese Utility Model Application Publication No. 18362/1983 (see FIG. 1).

<Problems to be solved by the invention> However, the installation site of the water drain hole is inside the bottom of the vehicle body, and the work of attaching and removing the water drain plug 9 must be done by going under the vehicle body, which is troublesome. In addition, it is easy to overlook, and there is a possibility that rainwater may remain stored for a long time, and there is a risk that the drain hole 7 may not be used effectively.

<Means for solving the problems> In order to solve the above problems, the present inventors
As a result of intensive development efforts, we have come up with an automobile trunk water drain plug with the following configuration.

With rear fender and trunk side panel,
In a drain plug made of a polymeric elastic material that is attached to a drain hole provided in a trunk side panel of a recess formed in the side bottom of an automobile trunk,
An eyelet-shaped plug body is provided with an annular groove on the outer circumference that is sealed and fitted to the inner circumference of the water drain hole, and a plug body is integrated with the plug body via a hinge portion and snaps onto the vehicle body side of the plug body. A notch is formed in one or both of the lid and the plug body so that a water outflow path is formed when the plug body is engaged with the lid. Features.

<Example> An example of the present invention will be described below based on the drawings. Note that the same reference numerals are used for the same parts as in the conventional example, and some explanations thereof are omitted.

What is shown in FIGS. 1 to 3 is an embodiment of the present invention.

An eyelet-shaped plug body 11 and a deep dish-shaped lid body 1 that is integrated from the plug body 11 via a hinge part 13 and can be engaged with the plug body 11 with a snap.
It consists of 5. And these drain plugs 9
A is usually synthetic rubber such as CR with good weather resistance,
Manufactured by injection molding using elastic plastic materials such as PVC.

The plug main body 11 has an annular groove 17 on its outer periphery that can be fitted while sealing the outer periphery of the drain hole 7, that is, the inner and outer surfaces of the trunk inside panel 3.
It is equipped with That is, this annular groove portion 17 is formed by opposing wall surfaces of an inner seal lip 11a and an outer seal lip 11b that seal the inner and outer surfaces of the trunk side panel 3. Further, the snap engagement between the plug body 11 and the lid body 15 is achieved by an annular engaged pawl 21 formed on the outer circumference of the plug body 11.
This can be achieved by the annular engaging pawl 23 formed on the inner inner periphery of the lid body 15.

Further, the annular engaging claw 23 of the lid body 15 is partially formed with a notch 23a, and when the plug body 11 is closed with the lid body 15, the through hole 1 of the plug body 11
2 and the recess 15a of the lid 15 to form a water outflow path P. Here, the notches 23a are formed in three equal parts so that the direction of the plug with respect to the drain hole 7 can be taken arbitrarily, but if the direction of attaching the plug is fixed, there is one cutout 23a. That's fine. Note that, as shown in FIG. 4, the notch 21a may be formed in the annular engaged claw 21 of the plug body 11, and furthermore, the notch 21a may be formed in both the annular engaged claw 21 and the annular engaged claw 23. You may.

Next, how the above embodiment is used will be explained.

As in the past, a drain plug is attached to the drain hole 7 of the trunk side panel 3. Even if the water enters the trunk room, it is discharged from the outflow path P formed by the notch 21a or 23a formed in the annular engaging claw 21a or the annular engaging claw 23a. Note that the discharge of rainwater L stops at the position of line H shown in FIG. 4, but the amount of residual rainwater at that time is small and evaporates quickly, so there is no problem.

In addition, even if water directly splashes on the drain plug from the outside of the vehicle while driving on a road with puddles, since the through hole 11a of the plug body 11 is closed by the cover body 15, almost no water will enter. Even if the water flows backward through the outflow path P and enters, there is no problem because it will be discharged in the same manner as above.

Note that, if the water outflow path P is blocked by dust or the like after long-term use, the dust can be easily removed by removing the lid 15 from the plug body 11.

<Operations and Effects of the Invention> The automobile trunk water drain plug of the present invention includes an eyelet-shaped plug body having an annular groove portion on the outer periphery that is sealed and fitted to the inner peripheral edge of the water drain hole, and a water drain plug from the plug body. It consists of a lid body that is integrated via a hinge part and can be engaged with a snap on the outside of the vehicle of the plug body, and the lid body is configured such that a water outflow hole is formed when the plug body is engaged with the lid body. By forming a notch in one or both of the plug body and the plug body, the following actions and effects are achieved.

Even if rainwater enters the trunk room, it is constantly discharged from the water outflow path, so that almost no rainwater accumulates in the recess formed at the side bottom of the trunk of the automobile between the rear fender and the trunk side panel. Therefore, the drain hole can be used effectively without the troublesome and easily overlooked task of periodically removing the drain plug. Furthermore, after long-term use, the water outflow path P
Even if the plug is clogged with dust, the dust can be removed by simply removing the cover from the plug body.
