Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is made of a flexible material such as rubber or synthetic resin that is removably fitted into a drainage hole drilled in a cross panel of a vehicle body, etc. Regarding improvements to drain plugs.

In the case of automobiles, waterproof measures such as weather strips B are taken to prevent rain or car wash water from penetrating into the car body A, as shown in Figure 1.

However, water droplets from panel joints, window opening edges, etc. may infiltrate into the bag-shaped portion A' of the vehicle body A, such as the floor panel and trunk C.

Therefore, in order to avoid the above-mentioned accumulation of infiltrated water, a drain hole D is provided in the floor panel or the trunk floor side plate F facing the rear fender E of the trunk C as shown in FIG.

However, if the drain hole D is left open, sewage, dust, etc. will enter the vehicle body A from here, so the drain hole D is closed with a rubber plug G as shown in the figure.
During normal times, this was closed by the fitting of the bag A', and the infiltrated water was stored in the bag-shaped part A', and the rubber stopper G was removed each time and the water was discharged from there.

Therefore, consideration has been given to eliminating the hassle of fitting and removing the rubber stopper G as described above, and as shown in Figure 3, it is possible to release the stored water H naturally while it is still fitted into the drain hole D, and from the outside. A water removal device using the drainage plug I, which can prevent sewage from entering, was developed by Kosho.
48-40255.

This drain device has a notch at the bottom of the drain hole D.
In addition to extending D', a thin flap piece J is formed on the outer periphery of the drain plug I fitted in the drain hole D, and the stored water H is caused to flow through the inner plate K due to its water pressure.
The thin flap piece J, which is in close contact with the
They are trying to open the above gap by draining the water through D' as shown by arrow L, and by using the vibrations of the car body.

Therefore, when using the above device, the formation of the thin flap piece J that is in close contact with the inner plate K during normal operation prevents the infiltration of sewage from the outside, but allows the water H stored in the bag-shaped part A' to flow. Water will not be discharged unless the water level reaches the required water level, and the above-mentioned gap obtained by expansion is small, so water will not be discharged smoothly, and the gap will easily become clogged with dirt, etc., ensuring that the stored water is completely discharged. This results in accelerated corrosion of vehicle body panels.

In view of the above-mentioned drawbacks of the conventional drainage plug, the present invention extends a pressing tongue from the plug body and forms a bent water discharge groove in the tongue, thereby removing sewage, dust, etc. from the outside. In addition to substantially preventing the infiltration of water into the vehicle body A, etc., it has the function of always allowing water to flow out to the outside. The aim is to have the
That is the purpose.

The present invention will be described in detail with reference to the embodiment shown in FIG.
The plug body 1 is preferably integrally molded from a flexible material such as rubber or soft synthetic resin such as vinyl chloride as in the conventional one, and has a locking protrusion 3.
and a pressing tongue piece 2 that protrudes outward from the flag body 1. In the illustrated example, the pressing tongue piece formed in a short shape from the base portion 1a of the plug body 1, which is disk-shaped, extends in the radial direction. The above-mentioned locking protrusion 3
is provided in an arc shape with a diameter smaller than that of the base plate part 1a so as to be fitted and locked into the drain hole D without water leakage from the back surface 1' of the base plate part 1a.

In this embodiment, an open recess 4 surrounded by the above-mentioned locking protrusion 3 is formed in the plug body 1, but this locking protrusion 3 is similar to the embodiment shown in FIG. 7 described later. It is not closed in an annular shape, and the opening recess 4 is open at the notch 4' on the side of the pressing tongue 2, and 3' in the figure is the locking protrusion 3, and the water is not closed. A fitting groove provided around the edge of the extraction hole D to be fitted and locked is shown.

Furthermore, the back surface 2' of the pressing tongue piece 2 is formed at the same height as the back surface 1' of the plug body 1, and the peripheral edge of the back surface 2' has a pair of left and right ridges lower than the above-mentioned locking protrusions 3. The guide vertical strips 5 ₁ 5 ₂ protrude integrally and continuously with the locking protrusion 3, thereby forming a drainage concave surface 6 with a drainage port 6' opened at the lower end side of the back surface 2'. The above-mentioned introduction port 9 for infiltrating water inside the vehicle is opened at the upper end side of the back surface 2' of the drainage concave surface 6, and in the illustrated example, the introduction port 9 communicates with the opening space 4 through the notch 4'. It has become a state.

Furthermore, in the present invention, in _the drainage concave surface 6, by providing backflow prevention protrusions 7, 7 _' , .
As shown by the dashed line in FIG. 4, recesses are provided between the backflow prevention protrusions 7, 7'... and the guide vertical strips ₅₁ , ₅₂ to connect the inlet port 9 and drain port 6'. A curved water discharge groove 8 that is connected is formed.

In the case of the same figure, the water discharge groove 8 is formed by providing backflow prevention protrusions 7, 7 _{' ,} . It is bent in a serpentine shape.

On the other hand, in the embodiments shown in FIGS. 7 and 8, the backflow prevention protrusions 7, 7' _, . . .
It is not connected to the drainage concave surface ₆ but is independent from the back surface 2' of the drain concave surface 6, and in FIGS.
Place a triangular prism-shaped object in several steps toward the drain port 6'.
Water discharge grooves 8 are arranged so that the arrangement of each stage is inconsistent with each other.
is bent into a wave shape, and the diameter of the columnar shape is
The length of the base of the triangular prism is greater than the width of the drain port 6'.

In addition, in the case of FIG. 7, unlike the one in FIG. 4 as described above, the locking protrusion 3 is closed in an annular shape, and therefore the opening recess 4 and the drainage concave surface 6 are in communication. However, when using such a device, a notch structure is provided in the drain hole D as shown in the dashed line in the same figure.
D' may be extended and used in such a manner that the water stored in the car, H, flows into the water discharge groove 8 of the drainage concave surface 6 from the cutout structure D'.

Therefore, in order to adopt the drain hole D in the trunk floor side panel F shown in FIG. 5 as shown in FIG. A hole is formed so as to reach the bottom surface, and the locking protrusion 3 is engaged with the hole, whereby the pressing tongue piece 2
are curved, and the guide longitudinal strips 5 ₁ , 5 ₂ and the backflow prevention protrusions 7 , 7 ′... come into contact with the joining slope M between the rear fender E and the trunk floor side plate F, and therefore, The stored water that has flowed into the bottom surface of the rear fender E is discharged from the open space 4 through the water discharge groove 8 to the outside from the drain port 6'.

Furthermore, FIG. 6 shows a case in which the method is applied to a drain hole D formed in a recess N' of a floor panel N, and in this case, the locking protrusion 3 is pushed in in the same manner as in the above embodiment. All you have to do is fit and lock it into the drain hole D.
In this way, the guide longitudinal strips 5 ₁ , 5 ₂ and the backflow prevention protrusions 7 , 7 ′ of the pressing tongue piece 2 come into contact with the panel surface of the concave portion N ′ around the hole D, and as a result, water is discharged. Groove 8 is held open.

Therefore, in this case, when water that has entered the vehicle flows into the recess N', the water flows into the open space 4 while bypassing the water discharge groove 8, and is discharged from the space 4 to the outside. It will be done.

In addition, in the case of the type shown in FIG. 7, as mentioned above, the water that has entered the car flows into the inlet 9 of the drainage concave surface 6 from the notch D' extending into the drainage hole D, and this water is further discharged into the water discharge channel. 8.
