ウエザーストリツプに関する。[Detailed Description of the Invention] Industrial Application Field This invention relates to a weather strip that is attached to a flange at the edge of an opening in a vehicle body to which a trunk lid, door, etc. of an automobile are attached.
従来の技術
従来、車体開口縁のフランジに取付けられるウ
エザーストリツプとしては第１図に示すものが実
施されていた。BACKGROUND ART Conventionally, a weather strip shown in FIG. 1 has been used as a weather strip attached to a flange at the edge of an opening in a vehicle body.

ジゴム製のシールリツプである。 1 is a welt portion having a substantially U-shaped cross section and is made of solid rubber as a base material; 2 is a reinforcing core bar embedded within the welt portion; 3 is a flange holding lip protruding from the inner facing surface of the welt portion 1; Reference numeral 4 denotes a seal lip made of sponge rubber that is integrally molded on the welt portion 1 so as to be in close contact with a lid such as a trunk lid, a door, or a window glass (not shown).
そして、このウエザーストリツプは、上記ウエ
ルト部１を拡開した展開状態で一体に押出成形さ
れ、かつこれを略Ｕ字状に折曲形成してある。 The weather strip is integrally extruded with the welt portion 1 in an expanded state, and is bent into a substantially U-shape.

プが倒れ、シール性が低下するという問題があつ
た。 However, with the above conventional configuration, there are problems in that the cost is higher due to the material cost of the sealing material 5 and the weight is considerably increased compared to the conventional weather strip that does not use the sealing material 5. Ta. In addition, when the weather strip is fitted to the vehicle body opening edge flange 6, a sponge rubber draining lip 8 is integrally molded on the vehicle outer side end of the welt portion 1 so as to be in close contact with the vehicle body panel 7.
There was a problem in that the weather strip fell down in the direction A as shown in the figure due to the reaction force, resulting in a decrease in sealing performance.
そこで、かかる問題点を解消するため、第２図

ルト部１の保持力を向上させウエザーストリツプ
の倒れ防止を図つている。 Therefore, in order to solve this problem, as shown in FIG. A protective lip 10 is formed, and the corner protective lips 10 and 11 are shaped so as to sandwich the vehicle body opening edge flange 6, thereby improving the holding power of the welt portion 1 and preventing the weather strip from falling down. There is.
しかしながら、かかるウエザーストリツプにあ

いという問題点があつた。 However, in the case of such a weather strip, when the welt portion 1 is inserted into the flange 6, the reaction force of the corner protection lips 10, 11 is large, so that the corner protection lips 10, 11 are deformed. The weather strip has a problem in that the workability of attaching the weather strip is poor because it is difficult to absorb variations in the plate thickness of the flange 6.
本考案は、上記従来の問題点に鑑み案出された

し易いようになつている。 FIG. 3 shows a first embodiment of this invention, in which 1 is a welt portion with a substantially U-shaped cross section and made of solid rubber, in which a reinforcing metal core 2 is embedded; A flange protection lip protruding from the inner facing surface of the welt part 1, 4 a seal lip integrally formed on the upper end of the welt part 1, 5 a viscous sealing material such as butyl rubber, 6 a flange at the opening edge of the vehicle body, and 7 the vehicle body. The panel 8 is a draining lip integrally formed on one end of the welt portion 1 on the right side in the figure. One end is connected to the inner bottom surface 1a of the welt section 1 at an inner corner of the welt section 1 on the draining lip 8 side, and a free end is oriented toward the inner facing surface 1b of the welt section 1 on the right side in the figure. A corner protective lip 11 on the side of the draining lip 8 is provided, the entirety of which bulges inward in an arcuate shape to form a space 9 inside as shown in FIG. A sub-rip 13 is formed protruding from the free end side of this corner protection lip 11, and the tip of this sub-rip 13 is a stop formed to protrude from the inner facing surface 1b of the welt portion 1 when the flange 6 is inserted. 12. Also, this subrip 1
The wall thickness t 1 of No. 3 is the wall thickness t 2 of the corner protection lip 11.
The corner protection lip 11 is formed thinner and easily deformed.

に防止できる。 Therefore, the corner protection lip 11 on the draining lip side has the sub-rip 13 formed protruding from the other free end side.
is formed to bulge inward of the welt portion 1, so that together with the other side corner protection lip 10,
In order to clamp the inserted opening edge flange 6, the weather strip is firmly fixed. Furthermore, a space corresponding to 9 in FIG. 2 is formed at the inner corner of the welt portion 1 by the corner protection lips 10 and 11, and this space is filled with a sealing material 5. The filling amount is sufficiently reduced. In addition, since the tip of the opening edge flange 6 is embedded in the sealing material 5, not only the sealing performance is improved, but also the adhesion of the weather strip is further strengthened. It is possible to reliably prevent the weather strip from tilting due to the reaction force of the weather strip.

ザーストリツプの取付作業性が良好となる。 Further, since the corner protection lip 11 is abutted against the inner surface of the welt part 1 via the thin sub-rip 13 formed protruding from the end, it is easily deformed when inserted into the opening edge flange 6, and the above-mentioned problem arises. Variations in the plate thickness of the flange 6 can also be absorbed, and the workability of attaching the weather strip can be improved.

成されている。 FIG. 4 shows a different embodiment of the present invention, in which an ultra-thin sub-rip 13 is attached to the free tip of the corner protective lip 11 on the draining lip side which is protruded from the inner bottom surface 1a of the welt portion 1. The corner protection lip 11 and the sub-rip 13 are formed in a protruding manner so as to abut against the inner facing surface 1b of the welt part 1.
It is formed in an arc shape so that it bulges inward from the inner corner.

止と取付作業性が更に良好となる。 Therefore, as in the first embodiment, strong adhesion and sealing properties of the weather strip can be obtained, and since the sub-rip 13 is formed with an extremely thin wall, the welt part 1 can be attached to the opening edge. Flange 6
When the weather strip is inserted into the weather strip, the corner protection lip 11 is more easily deformed, so that the weather strip is prevented from tilting and the installation workability is improved.

薄肉状のサブリツプ１３が突出形成されている。 FIG. 5 shows a different embodiment of the present invention, in which a draining lip side corner protective lip 1 is provided on the inner facing surface 1b of the welt portion 1 and bulges in an arc shape inward from the inner corner.
1 is provided in a protruding manner, and a thin sub-rip 13 is formed protruding from the end of this corner protection lip 11, the tip of which abuts against a stopper 12 protrudingly formed on the inner bottom surface 1a of the welt portion 1. has been done.
従つて、隅部保護リツプ１１の開口縁フランジ

となる。 Therefore, since the distance between the corner protection lip 11 and the point where it abuts the opening edge flange 6 is longer, when inserting the welt part 1 into the opening edge flange 6, the action of the thin sub-rip 13 and the Since the outer corner protection lip 11 becomes more easily deformed, the weather strip installation workability becomes even better.
また、上記隅部保護リツプ１１が、ウエルト部
１の内側対向面１ｂに突出形成されているので、
この隅部保護リツプ１１はフランジ保持リツプを

よび重量が軽減される。 Furthermore, since the corner protection lip 11 is formed to protrude from the inner facing surface 1b of the welt portion 1,
This corner protection lip 11 also serves as a flange holding lip and has a simple shape, reducing cost and weight.

る。Effects of the invention As is clear from the above explanation, according to the weather strip according to the invention, the weather strip is formed to bulge inward at both internal corners of the welt part, and the corners that clamp the vehicle body opening edge flange. It is equipped with a protective lip and a viscous sealing material filled in the inner bottom between the corner protective lips, and furthermore, the tip of the corner protective lip on the side of the draining lip has an abutment part formed on the inner surface of the welt part. Since the weather strip is designed to abut through a thin-walled lip, strong adhesion and sealing performance of the weather strip to the vehicle body opening edge flange can be obtained. Since the protective lip on the corner of the drainer lip is easily deformed when installing the weather strip, the workability of attaching the weather strip is improved, and an excellent practical effect can be obtained.
