Description

[Detailed description of the invention] The present invention relates to a drip weather strip,
In particular, the present invention relates to improvements in drip weather strips that seal between the roof side and the door of an automobile.

As shown in FIGS. 1 and 2, in conventional vehicle doors, door sash parts 1a, 1b and door bodies 2a, 2b are integrally formed by joining outer panels 3a, 3b and inner panels 4a, 4b. There are some formed in Door 2 with this structure
A drip weather strip 6 that seals between the door sash portions 1a and 1b of the doors a and 2b and the roof side portion 5 is generally attached to the tip of a drip channel 7 provided along the roof side portion 5. The base 8 is fitted, and when the doors 2a, 2b are closed, the lip part 9 extending along the upper edge of the base 8 is formed to cover the drip channel 7. By making elastic contact with the parts 10a and 10b, a seal is created between the roof side part 5 and the door sash parts 1a and 1b.
Note that reference numbers 11a and 11b in FIG.
12 is a center pillar, 13 is a roof panel, and 14 is an inner roof side rail.

However, in the case of such a conventional drip weather strip 6, since it is arranged horizontally along the drip channel 7,
Rainwater flowing down from the roof panel 13 is removed from the door 2.
As shown in FIG. 3, at certain locations a and 2b, the lip portion 9 is blocked by elastic contact with the inner peripheral edge 10a of the door sash portion 1a, and the door weather strip 11a or flowing down passes over the lip portion 9. center pillar 6.
Between the outer doors 2a and 2b, the
As shown in the figure, since there is no door sash with which the lip 9 comes into elastic contact, overflowing rainwater passes over the lip 9 and travels along the inner circumferential surfaces of the door sash 1a, 1b to the corners of the door weather strips 11a, 11b. The corner portions 15a, 15 fall down to the corners 15a, 15b, resulting in unstable sealing pressure and sealing area.
There is a risk that the rainwater may enter the room through the doors 2a, 2b, or accumulate on the upper edges 16a, 16b of the door weather strips 11a, 11b, and fall as raindrops when the doors 2a, 2b are opened. In particular, when washing a car, there is a large amount of water, so the door weather strip 11
There was a problem in that the water accumulated on the upper edges 16a, 16b of the doors 2a, 11b increased, and a large amount of rain dripped when the doors 2a, 2b were opened.

The present invention has been made with attention to such conventional problems, and its purpose is to prevent rainwater etc. from flowing down from the drip weather strip to the door weather strip. In particular, the purpose is to prevent rainwater from entering the vehicle interior and raindrops from occurring when the door is opened.

In order to achieve the above object, the present invention provides a drainage channel in which the water inlet is connected to the seal part and the drain outlet is located below the upper edge of the door weather strip, and extends along the drip channel. The gist is that it is provided at a location corresponding to the center pillar of the seal portion.

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

5 and 6 show a first embodiment of the present invention, which is attached along a drip channel 7 of a roof side part 5, and has a base part 8 and a lip part 9 which is a seal part. A drainage channel forming member 18 is provided in the lip portion 9 of the formed drip weather strip 17 at a portion corresponding to the center pillar 12. This drainage channel component 18 includes a bottom wall portion 19 formed in a predetermined shape from hard solid rubber like the base portion 8, and a drip weather strip 1.
Similar to the lip portion 9 of No. 7, the side wall portions 20a and 20b are made of soft sponge rubber and are bent downward along both side edges of the bottom wall portion 19, forming a substantially U-shaped cross section. The base end of the drip weather strip 17 is attached to the base part 8 of the drip weather strip 17, and the side wall part 20
The proximal ends of the inner panels 4a, 20b of the door sashes 1a, 20b are integrally connected to the outer wall of the lip portion 9 in an unexpanded manner to form the water inlet 21, and the tapered ends of the inner panels 4a, Door weather strip 11a adhesively fixed to 4b,
A drain port 22 extending downward from the upper end portions 16a, 16b of 11b to the lower side thereof is formed. As a result, an inverted V-shaped drainage channel 23 surrounded by the side walls 20a and 20b is formed between the water inlet 21 and the drain port 22. In this embodiment, a fixing protrusion 24 that also serves as positioning is formed at the location where the drainage channel 23 is disposed on the roof side portion 5, and as shown in FIG. By fixing the bottom wall portion 19 of the drainage channel component 18 arranged along the shape to the projection 24 with the tapping screw 25, the drainage channel component 1 is fixed.
8 is fixed.

Therefore, when the doors 2a, 2b are closed, the lip portion 9 and the side wall portions 20a, 20b of the drainage channel forming member 18 are closed.
The upper side of the door 2 is in elastic contact with the inner peripheral edges 10a and 10b of the door sill parts 1a and 1b.
It is exposed toward the outside of the vehicle body between a and 2b. As a result, at the portions where the lip portion 9 of the drip weather strip 17 comes into elastic contact with the door sash portions 1a and 1b, rainwater etc. that have flowed down into the drip weather strip 17 are blocked by the drip portion 9, as in the conventional case. This prevents the weather from flowing in the longitudinal direction of the vehicle body along the drip channel 7 over the lip portion 9 and flowing down to the door weather strips 11a and 11b, and at the portion corresponding to the center pillar 12. Rainwater, etc. overflowing from the upper edge of the lip part 9 of the drip weather strip 17 is guided into the drainage channel 23 from the water inlet 21, and
The liquid flows down along the bent shape of and is discharged downward from the discharge port 22 along the outer panel of the center pillar 12. Therefore, water overflowing from the lip portion 9 is reliably prevented from flowing down the roof side portion 5 to the corner portions 15a, 15b and upper edges 16a, 16b of the door weather strips 11a, 11b. Ru.

7 and 8 show a second embodiment of the present invention, in which a notch 26 is provided in the lip portion 9 of the drip weather strip 17 at a portion corresponding to the center pillar 12, and a cutout portion 26 is provided in the lip portion 9 of the drip weather strip 17. Panel 13
Rainwater and the like flowing down from the drain channel 7 to the drip channel 7 is forcibly introduced into the drainage channel 23 from the notch 26, and other aspects are the same as in the first embodiment.

Therefore, in this embodiment, the drip channel 7
Even a small amount of rainwater, etc. that has accumulated in the water can flow from the notch 26, improving the drainage effect.

In each of the above embodiments, the case where the drainage channel is formed by a member having a substantially U-shaped cross section has been described, but the present invention is not limited to this shape, and for example, the drainage channel may be formed within a cylindrical member. It may be something that has been done. Further, in the above embodiment, the case where the drainage channel constituent members are formed integrally with the drip weather strip main body has been explained, but in the present invention, they are provided separately and the two are connected by means such as adhesive. Needless to say, the drainage channel constituting member may be made of a material different from that of the seal portion. Furthermore, it goes without saying that the means for fixing the drainage channel constituent members is not limited to the case where a protrusion is provided on the roof side part and fixed with a tapping screw as in the above embodiment; instead, a concave part is provided on the roof side part for positioning. Alternatively, the bottom wall portion of the drainage channel constituting member may be fixed by adhesive means.

As explained above, according to the drip weather strip according to the present invention, rainwater, etc. that has flowed down from the roof panel into the drip channel can be prevented from overflowing at the part corresponding to the center pillar. Even if water accumulates in the corners and upper edges of the door weather strip, it will be difficult to prevent water from accumulating in the corners or the upper edge of the door weather strip as in the case of conventional door weather strips. It is possible to reliably prevent water from entering the vehicle interior from the corners and raindrops caused by water collecting on the upper edge when the door is opened. In particular, when washing a car with a large amount of water, it prevents rainwater from flowing down from the drip weather strip to the door weather strip, which prevents rainwater from entering the vehicle interior and raindrops from forming when the door is opened. big.
