Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a drainage structure for a weatherstrip mounted along a window opening on a side of a vehicle.

[Conventional technology]

Generally, as a weather strip on a vehicle body side surface, particularly on a vehicle body side surface, a weather strip disclosed in Japanese Patent Application Laid-Open No. 61-94815 is known.

This weatherstrip has a hollow part inside the main body as a drainage channel and a drainage hole at the lower end.It is most often used, but it is used on the side of an automobile body with a sashless type door panel. However, there is a problem that the sealing performance against water leakage is poor due to low support rigidity of the window glass and direct contact of the window glass.

As a solution to this problem, there is a weather strip body provided with a seal lip portion, and this seal lip portion is pressed by window glass,
Improves sealing performance. In addition, since the weather strip forms a drain groove having a substantially U-shaped cross section between the seal lip portion and the main body, a drain hole communicating with a drain passage is formed at the lower end of the drain groove to allow water collected in the drain groove. I try to discharge.

[Problems to be solved by the invention]

However, according to conventional weatherstrips,
There are the following problems.

When closing the door, the weatherstrip is pressed by the window glass and deforms to a considerable extent. for that reason,
The drainage groove formed by the main body and the seal lip portion is also pressed, so that water is blocked, and water accumulates in the drainage groove.
In this state, when the door is opened, the water accumulated in the drain may scatter and wet the inside of the vehicle. In addition, when water accumulates in the drainage ditch, the water may travel along the window glass and adhere to the inside of the window glass, so that the quality is significantly impaired and improvement has been desired.

The present invention has been made in view of the above problems, and has an object to provide a weather strip drainage structure that has excellent drainage regardless of the state of a door, does not wet the inside of a vehicle, and does not impair the quality. .

[Means for solving the problem]

In order to solve the above-mentioned problem, the present invention forms a drain passage inside a main body which is mounted along a window opening on a side surface of a vehicle body, and a seal lip portion pressed by a window glass of a sashless type door panel on the main body. A drain groove formed by the seal lip portion and the main body adjacent to the drain passage, and a drain hole formed at a lower end of the drain groove to communicate with the drain passage. Aside from a drain hole provided at the end of the drain groove formed by the seal lip portion and the main body, a communication drain hole communicating with the drain passage is formed near an intermediate portion of the drain groove. A step is provided between the position of the edge of the communication drain hole on the upper side of the drain groove wall and the position of the edge of the communication drain hole on the lower side of the communication drain hole to form a bent communication drain hole, Of the upper edge The drainage structure of the weatherstrip was characterized in that the water drainage channel was positioned so that the water flowing down the upper drainage channel was guided to the drainage channel. Things.

[Action]

According to the present invention, since a drain hole communicating with the drain passage is formed in the drain groove above the drain hole at the lower end of the drain groove,
When closing the door, even if the window glass presses on the drain and the water does not flow into the drain hole at the lower end, the water in the drain can be discharged by the drain hole on the upper side, and the water is drained into the drain. It can prevent accumulation. Moreover, since the position of the edge of the upstream communication drain hole is formed at a position lower than the position of the edge of the downstream communication drain hole on the border of the communication drain hole formed in the drain groove, the upper drain groove is formed. The flowing water flows from the communication drain hole to the lower drainage passage, and can be reliably drained.

〔Example〕

An embodiment according to the present invention will be described below with reference to the drawings.

FIG. 1 is a side view showing the entire weather strip, FIG. 2 is an enlarged view of a portion Z in FIG. 1, and FIG. 3 is II in FIG.
FIG. 4 is a sectional view taken along the line II-II 'of FIG.

As shown in FIGS. 1 to 3, the weather strip A
Consists of a hollow main body 1 that is mounted along the window opening on the side of the body B of an automobile or the like. The main body 1 is composed of a front portion 1a mounted on a front pillar, a center portion 1b mounted on a center pillar, and a rear portion 1c mounted on a rear pillar. A drain hole 2a for discharging water from the passage 2 is formed. Since the water draining hole 2a is formed in a state in which the back surface of the lower end of the main body 1 is completely open, dust and the like are hardly clogged at the lower end, and even if clogged, water does not stop.

A retainer engaging portion 3 that engages with the vehicle body B is formed on the back surface side of the main body 1. The retainer engaging portion 3 is a groove having a substantially concave cross section and is formed along the longitudinal direction of the main body 1. ing. A cover lip portion 4 formed so as to hang downward from the upper portion of the main body 1, a substantially arc-shaped contact portion 5 formed inside the cover lip portion 4, A seal lip portion 6 formed so as to protrude upward from the front surface side is provided, and the seal lip portion 6 and the main body 1 form a drain groove 7. At the lower end of the main body 1, an engaging portion 8 and an engaging pin 8a for attaching the main body 1 to the vehicle body B are provided.

As shown in FIG. 3, the contact portion 5 comes into contact with the end of the side window glass SW, and is pressed by the end of the side window glass SW as shown by a virtual line in FIG. It has been designed to prevent water leakage. In addition, the seal lip portion 6 comes into contact with the inner edge of the side window glass SW, and as shown by the imaginary line in FIG. 3, is pressed by the inner edge of the side window glass SW to prevent water leakage. To prevent it. And
The cover lip portion 4 covers an end portion and an outer edge portion of the side window glass SW, and prevents water from hitting a contact portion between the contact portion 5 and an end portion of the side window glass SW. It prevents the phenomenon of being sucked out at high speed.

As shown in FIGS. 2 to 4, the drain groove 7 has a substantially U-shaped cross section, and a lower end side drain hole 7a communicating with the drain passage 2 is formed at the lower end thereof. Above the hole 7a, an intermediate drain hole 7b communicating with the drain passage 2 is formed. An intermediate drain hole 7b, which is a communication drain hole provided in the center portion of the drain groove 7, is connected to the intermediate drain hole 7b.
, The upper edge 7c of the intermediate drain hole 7b of the drain groove 7 is positioned closer to the drainage path 2 than the position of the lower edge 7d, and the water flowing from above the drain groove 7 To the drain path 2. That is, since the lower edge 7d of the drain groove 7 has the lower edge 7c of the upper intermediate drain hole 7b, the flowing water does not reach the lower edge 7d.
When the edge 7c of the upper intermediate drain hole 7 is further bent toward the drain passage 2, the water remaining in the drain groove 7 from above drops from the intermediate drain hole 7b and drops into the drain passage 2b. Flows to

Next, the operation and action of the weather strip A will be described.

When the door is closed, the side window glass SW comes into contact with the contact portion 5 and the seal lip 6 of the main body 1 and presses it, as shown by the imaginary line in FIG. At this time, while the seal lip 6 is pushed upward, the seal lip 6 abuts against and presses against the inner side edge of the side window glass SW, while the contact portion 5 abuts against the end of the side window glass SW. Press. Although the seal against water is made in this way, the sash-less door has absolutely lower support rigidity for the side window glass SW than the sash-equipped door. May seep out.

Thereby, water accumulates in the drain groove 7 formed by the seal lip 6 and the main body 1. The water accumulated in the drain groove 7 flows from the lower end drain hole 7a and the intermediate drain hole 7b to the drain passage 2 and is discharged to the outside from the drain hole 2a of the drain passage 2.

In the state where the door is closed as described above, the drain groove 7 is also squeezed to be tight and the water flow is not so good. However, as described above, the lower end drain hole is provided at the lower end of the drain groove 7 and the upper side thereof. With the provision of the drain hole 7a and the intermediate drain hole 7b, the water accumulated in the drain groove 7 can be quickly discharged.
In addition, the position of the upper edge 7c of the intermediate drain hole 7b of the drain groove 7 is lower than the position of the lower edge 7d, that is, the position of the intermediate drain hole 7b. The shape is not formed on the wall plane of the drainage groove 7, but a step is provided between the upper edge 7c and the lower edge 7d so that the upper edge 7c is connected to the drain path 2
Because it is positioned on the side, the water flowing above the drain groove 7 falls from the intermediate drain hole 7b to the drain passage 2 and flows.
Therefore, when the door is opened, the water accumulated above the drain groove 7 is completely drained, so that it is possible to prevent the water from adhering to the inner surface of the side window glass SW. Therefore, the quality of the vehicle body can be improved.

The present invention has improved the inconvenience in the case of a sashless type door, using a weatherstrip to increase the support rigidity of the side window glass in the sashless type, and using an appropriate thickness and material for the weatherstrip. Select In addition, since the door mirror support also serves to support the side window glass,
This support is slightly inward. Therefore, the pressing force of the side window glass in contact with the weather strip is increased, and the drain groove formed by the pressing of the side window glass is closed. Therefore, it is preferable that the intermediate drain hole 7b formed in the center of the weather strip is formed at a position slightly higher than the position where the door mirror stay contacts.

The present invention is not limited to the above embodiment, for example,
A plurality of intermediate drain holes may be provided at regular intervals.

[Effect of the invention]

The present invention is configured as described above, and has the following effects.

A drain hole at the lower end of the drainage groove and a drainage hole above it are provided to communicate with the drainage channel, so that even if the drainage groove is compressed by closing the door, the water collected in the drainage groove can be quickly drained. Can be. In addition, since the position of the upper edge of the intermediate drain hole is lower than the position of the lower edge of the intermediate drain hole formed at the boundary of the intermediate drain hole formed in the drain groove, the water on the upper side of the drain groove is formed. Flows and falls from the intermediate drain hole to the drain passage, so that a large amount of water does not flow below the drainage ditch. Therefore, drainage can be reliably performed even if the downstream side of the drainage groove is closed.

Therefore, even if the door is opened, the inside of the vehicle is not wet. Further, since water does not accumulate in the drain ditch, water does not adhere to the inside of the window glass, and the quality can be improved.
