Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a weather strip, and particularly to a weather strip.
This invention relates to an improvement in a weather strip for a vehicle windshield, which has a water draining structure that prevents water from entering a single compartment from the windshield holding part of the strip.

Generally, a rear window glass 1Fi as a vehicle window glass, for example, as shown in FIGS. 1 and 2,
It is attached to the window opening 7 lange 2 of the vehicle body via a weather strip W.

In this type, the weather strip W#'i
, has a mounting groove 3 on its outer circumferential surface to be fitted into the flange 2 of the window opening 7, and a bottom surface 5 to which a sealing material 4 is applied on the outside thereof, while holding the rear window glass 1 on its inner circumferential surface. It has a fitting groove 6, and the weather strip W
Fi and the sealing material 4 are used to maintain a watertight connection with the vehicle body.

However, in such a weather strip, rainwater, etc. 7 that flows down along the outer surface of the rear window glass 1 during rainy weather or when washing the car is absorbed by the weather strip I.
There is a risk that it may enter the fitting groove 6 of the J-tube W and enter the vehicle interior R as shown by arrow A through the minute gap between the fitting groove 6611 and the glass surface.

Therefore, in the past, as shown in FIG.
A suitable number of water passages 8 are provided to communicate the bottom of the fitting groove 6 with the outer side of the sealing material 4 attachment part of the weather strip helmet, and as shown in the path of arrow B, the fitting groove 6 is connected to the bottom of the fitting groove 6. Rainwater, etc. 7 that has entered the inside of the weatherstrip WO is guided to the outside of the weatherstrip W through the water drain passage 8, and the weatherstrip WO bottom Wi
The rainwater, etc. 7 is allowed to pass through a space 10 between the vehicle panel 5 and the vehicle body panel 9, and the rainwater, etc. is discharged to the outside of the vehicle from an engine 11 section 11 of the vehicle body that is offset in the vehicle width direction from the water drain passage 8. The following items are provided. In addition, 12 in Fig. 1 and 211 is a weather-resistant one from the viewpoint of weight reduction.
This is a cavity formed inside the strip W along the longitudinal direction.

However, in such a conventional weather strip, since the vehicle body panel 9 has a surface that supports the inclined end surface of the windshield 1, that is, a surface that is inclined downward on the inside of the vehicle interior, it is difficult to protect the weather strip during rainy weather or when washing the car. , rainwater, etc. may accumulate in the space 10 between the bottom surface 5 of the weather strip W and the vehicle body panel 9, and this accumulated rainwater, etc. 7 flows back through the water drain passage 8, and the rear window glass 1 There was a risk that the particles would enter the vehicle interior through the gap between the fitting groove 6 and the fitting groove 6.

The present invention has been made based on the above-mentioned viewpoints, and its purpose is to prevent rainwater, etc., flowing back from the water drain passage in the weather strip around the windshield of a vehicle from penetrating into the vehicle interior. It is an object of the present invention to provide a weather strip that reliably prevents the above.

The gist of the present invention is to focus on the cavity formed in the weatherstrip, and to form an inner water drainage passage that communicates the bottom of the fitting groove of the weatherstrip with the cavity, and to Cavity and above weather) IJ
The outer water drain passage that communicates with the outer part of the sealing material attachment part of the knob is connected to the inner water drain passage in the longitudinal direction of the IJ knob. This is a weatherstrip formed by applying J.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

In the first embodiment shown in FIGS. 113 and 411K, the basic structure of the weather strip W that holds the rear window glass 1 is that the outer circumferential surface of the weather strip W has a
It has a mounting groove 3 in which the rear window glass 1 is attached, and a bottom surface 5 and 1 in which a sealing material 4 is applied to the outside thereof. It has a cavity 12 along the longitudinal direction.

In this example, at φ, rear window glass 10 lower IIK
In the weather strip W located, an inner water drain hole connecting the bottom of the fitting groove 60 and the cavity 12 is appropriately installed Wk.
The power is distributed to the inner water drain 20#f, slanting diagonally downward toward the outside.

Further, the weather strip WK located on both sides of the lower part of the rear window glass 1 is located outside the cavity 12 and the sealing material 4 attachment portion of the weather strip W, for example, the outer surface portion 21.
A pair of outer drainage passages η are formed which communicate with the
This outer water drainage passage 22 is
It is provided offset from the inner drain passage in the longitudinal direction of the drain passageway, and is arranged to be inclined diagonally downward toward the outside.

Therefore, according to the rear window glass weather strip according to this embodiment, the rainwater that flows down along the outer surface of the rear window glass 1 during rainy weather, car washing, etc. is 7F! , and reaches the bottom of the fitting groove 6 through the gap with the fitting groove 6 of the rear window glass 1. In this state, the rain channel 7Fi has reached the bottom of the fitting groove 6, and the inner water drainage channel 20
The rainwater in the cavity 12 flows in the vehicle width direction and is discharged to the outside of the vehicle through the outer drainage passage 22.

Also, when washing a car, car wash water 7 is splashed onto the outer surface 21 of the IJ knob W. At this time, the car wash water 7 reaches the cavity 12 through the outer water drain passage 22, but does not directly reach the inner water drain passage 9, which is offset by NK from the outer water drain passage n. And cavity part 1
The car wash water 7 that has reached the interior of the cavity 12 flows along the longitudinal direction at the lower part of the cavity 12, but as soon as the water pressure on the passage n disappears, it connects with the outer drainage passage 22 and flows outside. Since the water is discharged, it does not have the force to flow back toward the inner water drain passage. Therefore, the situation #i in which the car wash water 7 reaches the fitting groove 6 due to backflow through the water drainage passage consisting of the outer water drain passage η, the empty ij 4 portion 12, and the inner water #Ft flow path is avoided, and There is absolutely no reason for the car wash water 7 to enter the vehicle interior RK through the gap between the rear window glass 1 and the fitting groove 6.

Furthermore, in this embodiment, the outer water drain passage 22#i
From the corner facing the outer surface portion 21 of the weather strip W, the bottom li5 of the weather strip W and the vehicle body panel 9
without being affected by the mounting position of the sealing material 4 between the
The #1 insert 1 that has entered the fitting groove 6 can be reliably discharged from the vehicle. That is, in the case where the outer water drain passage η is formed facing the bottom surface 5 of the weather strip helmet, the outer water drain passage η may be formed inside the seal material 4 depending on the installation error of the seal material 4. In such a case, there is a problem that the effusion calyx 7 discharged from the outer water drainage passage 22 may enter the single room through the gap between the weather strip W and the vehicle body. In the above embodiment, this problem is also solved.

It should be noted that the present invention is not limited to those shown in the above embodiments. For example, as shown in FIG. An outer water drain passage n is provided that communicates the bottom surface 5, which is the outer side of the sealing material 4 attachment part of the strip W, with the cavity 12, and a water drain passage n is provided in the vehicle body panel 9 offset in the vehicle width direction from the outer water drain passage 22. An embossed portion 11 may be formed, and in this case, the opening on the weatherstrip bottom surface 5 side of the outer water drain passage n can be set at the highest part of the bottom surface 5 without being affected by the presence of the lip L of the weatherstrip W. Therefore, even if water accumulates in the space 10, it will not flow back. In addition, the 6th [IK 1 embossed part 11 on the vehicle body side as shown]
Instead, a notch n for water drainage is formed in a part of the weather strip W to improve water drainage. Further, in the above embodiment, the present invention is applied to the weather strip W located at the lower part of the rear window glass 1, but the present invention is applied to the weather strip W located at the lower part of the rear window glass 1.
The present invention may be applied to weather strips located on the sides. Further, in the above embodiments, the present invention is applied to the weather strip W of the rear window glass 1, but the present invention can be applied to all vehicle windshields such as front windshields and side windshields. Of course.

As described above, according to the weatherstrip according to the present invention, an inner water drainage passage is formed that communicates the bottom of the fitting groove for holding the windshield of the weatherstrip with the cavity, and the The outer water drain passage that communicates with the outer part of the weatherstrip where the sealing material is attached is offset from the inner water drain passage with respect to the longitudinal direction of the weather strip, so that it can be easily used in rainy weather or when washing a car. Not only can rainwater that has entered the fitting groove from the windshield side be drained out of the vehicle, but it can also completely block the backflow of rainwater from the outside of the IJ knob. It is possible to reliably prevent rainwater, etc., from entering the single room.
