図2に示すウェザストリップを図3に示すように湾曲させてコーナに装着したとき、コーナ中央部付近で脚部2bが図4に示すように浮き上がり、図3に示すような波打ち現象を生じて外観不良を来たすことがある。   When the weather strip shown in FIG. 2 is bent and attached to the corner as shown in FIG. 3, the leg 2b is lifted near the center of the corner as shown in FIG. There may be a bad appearance.

また図2に示すウェザストリップは、図5に示すように脚部2bが閉じてグリップ2をフランジ1に差し込むときの作業性が悪くなることもある。   Further, the weather strip shown in FIG. 2 may have poor workability when the leg 2b is closed and the grip 2 is inserted into the flange 1 as shown in FIG.

本発明は、上記の問題を生ずることがない、トランクルーム用或いはバックドア用のウェザストップを提供することを目的とする。   An object of the present invention is to provide a weather stop for a trunk room or a back door that does not cause the above-described problems.

請求項1に係る発明は、自動車のトランクルーム開口部周縁或いはバックドア開口部周縁のフランジ1に差し込んで取付けられるグリップ12と、該グリップ12より突設され、トランクリッド3或いはバックドアを閉じたとき、トランクリッド3或いはバックドアに弾接する中空シール部13を有し、前記グリップ12は車内側の脚部12bと、中空状をなし車体パネル5に両面粘着テープ14によって接着される車外側の脚部12aを有するウェザストリップ11において、前記車内側の脚部12bは中空状をなすと共に、ガーニッシュ8端部に被さるカバーリップ16を有し、しかもフランジ1とガーニッシュ端との間に遊びを生じない程の厚肉に形成されて収まり、ガーニッシュ端に押込まれて押し潰されることを特徴とする。
The invention according to claim 1 includes a grip 12 that is inserted into and attached to the flange 1 at the periphery of the trunk room opening or the back door opening of an automobile, and is protruded from the grip 12 to close the trunk lid 3 or the back door. And a hollow seal portion 13 that elastically contacts the trunk lid 3 or the back door. The grip 12 has a leg portion 12b on the inner side of the vehicle and a leg on the outer side of the vehicle that is hollow and bonded to the vehicle body panel 5 by a double-sided adhesive tape 14. in weather strip 11 having a section 12a, the vehicle inner side of the leg portion 12b along with to such a hollow shape, a cover lip 16 overlying the garnish 8 ends, yet produce play between the flange 1 and the garnish end It is characterized by being formed so as to be as thick as possible and being crushed by being pushed into the garnish end .

請求項3に係わる発明は、請求項1又は2に係わる発明において、前記車外側の脚部は、グリップ内側にフランジに弾接する保持リップを有することを特徴とする。
The invention according to claim 3 is the invention according to claim 1 or 2, characterized in that the leg portion on the outside of the vehicle has a holding lip that elastically contacts the flange inside the grip .

請求項1に係わる発明によると、車内側脚部が中空で、ガーニッシュ取付時にガーニッシュ端に押込まれると、弾性変形し、フランジへの弾着力を強めて保持力及びシール力を向上させることができる。またグリップの車内側の脚部はフランジとガーニッシュ端との間に遊びができる図2に示す従来のウェザストリップのグリップ2の車内側脚部2bよりも厚肉であるため剛性が増し、しかも図2に示すフランジ1とガーニッシュ8との間に車内側脚部が開きうる遊びがないため、コーナ取付時に図4に示すように浮き上がって、図3に示すような波打ち現象が生じにくくなり、外観不良が生じにくくなる。また車内側脚部の剛性が増すことにより、脚部が閉じにくくなり、フランジへの差込みに支障が生じにくくなる。
According to the first aspect of the present invention, the inner leg portion of the vehicle is hollow, and when it is pushed into the garnish end when the garnish is attached, it is elastically deformed, and the holding force and the sealing force can be improved by increasing the elastic force to the flange. it can. Further, since the inner leg portion of the grip is thicker than the inner leg portion 2b of the grip 2 of the conventional weatherstrip shown in FIG. 2 which can play between the flange and the garnish end, the rigidity is increased. Since there is no play that can open the inner leg between the flange 1 and the garnish 8 shown in FIG. 2, it floats as shown in FIG. 4 when the corner is attached, and the undulation phenomenon shown in FIG. Defects are less likely to occur. Further, since the rigidity of the vehicle inner leg portion is increased, the leg portion is difficult to close, and the insertion into the flange is less likely to occur.

請求項2に係わる発明によると、グリップをフランジに差込む際、傾斜部ないし湾曲部がガイドとなってフランジに差込み易くなり、作業性が向上する。   According to the second aspect of the present invention, when the grip is inserted into the flange, the inclined portion or the curved portion serves as a guide and is easily inserted into the flange, thereby improving workability.

請求項3に係わる発明によると、保持リップがフランジに弾接することによりグリップのフランジへの保持力が増すと共に、止水性が向上し、車外側からの水の浸入による水洩れをより確実に防ぐことができる。   According to the invention of claim 3, the holding lip is brought into elastic contact with the flange, whereby the holding force to the flange of the grip is increased, the water stoppage is improved, and the water leakage due to the ingress of water from the outside of the vehicle is more reliably prevented. be able to.

以下、本発明の実施形態のウェザストリップを図面により説明する。
図6に示すウェザストリップ11は、トランクルーム開口部周縁のフランジ1に差し込まれるグリップ12と、該グリップ12より突設され、図1に示すトランクリッド3を閉じたとき、該トランクリッド3に弾接してシールする、図2に示す中空シール部4と同一構造の中空シール部13となり、グリップ12は、車外側の脚部12aと車内側の脚部12bを有し、車外側の脚部12aは図2に示す脚部2aと同様、断面略三角形の中空状をなし、底部で車体パネル5に両面粘着テープ14により接着して取付けられている。そして内側にはフランジ1に弾接する保持リップ15が一体形成されている。
A weather strip according to an embodiment of the present invention will be described below with reference to the drawings.
The weather strip 11 shown in FIG. 6 is provided with a grip 12 inserted into the flange 1 at the periphery of the opening of the trunk room, and protrudes from the grip 12 so as to elastically contact the trunk lid 3 when the trunk lid 3 shown in FIG. 2 to form a hollow seal portion 13 having the same structure as the hollow seal portion 4 shown in FIG. 2, and the grip 12 has a vehicle-side leg portion 12a and a vehicle-side leg portion 12b. Like the leg part 2a shown in FIG. 2, it forms a hollow shape with a substantially triangular cross section, and is attached to the vehicle body panel 5 by a double-sided adhesive tape 14 at the bottom. A holding lip 15 that elastically contacts the flange 1 is integrally formed inside.

車内側の脚部12bは、図示するように中空状をなし、車内側にグリップ12の開口に向かって拡開する傾斜部12cを備えている。そしてガーニッシュ8端部に被さるカバーリップ16を有している。
The leg portion 12b on the vehicle inner side is hollow as shown in the figure, and includes an inclined portion 12c that expands toward the opening of the grip 12 on the vehicle inner side. And it has the cover lip 16 which covers the garnish 8 edge part.

図7は、前記ウェザストリップ11のグリップ12をフランジ1に差込み、ガーニッシュ8を取付けた状態を示すもので、中空状の車内側脚部12bは、厚みがフランジ1とガーニッシュ端との間の隙間より大で、取付け状態においてフランジ1とガーニッシュ端との間に遊びを生じないほどの厚みを有し、フランジ1へ差込み後、ガーニッシュ8を取付けるときには、該ガーニッシュ端に押込まれて押し潰され、フランジ1への弾着力を強めてフランジ1への保持力とシール力を増し、また車内側への変形を規制されてコーナ装着時にフランジ1より浮き上がることがないようにしてある。   FIG. 7 shows a state in which the grip 12 of the weather strip 11 is inserted into the flange 1 and the garnish 8 is attached. The hollow inner leg 12b has a thickness between the flange 1 and the garnish end. It is larger and has a thickness that does not cause play between the flange 1 and the garnish end in the mounted state. When the garnish 8 is attached after being inserted into the flange 1, it is pushed into the garnish end and crushed. The holding force and the sealing force to the flange 1 are increased by increasing the elastic force to the flange 1, and the deformation to the inside of the vehicle is restricted so that it does not float from the flange 1 when the corner is mounted.

本実施形態のウェザストリップによると、以上のようにフランジ1への保持力とシール力が増すこと、車内側脚部12bは中空状で、中実に比べ、その分、重量が軽減されること、車内側脚部12bは、中空状であるとはいえ、図2に示す従来のウェザストリップの車内側脚部2bよりも厚肉で、剛性を有し、しかも上述するように車内側への変形を規制されるためにフランジ1より浮き上がって図3に示すような波打ち現象を生ずることがないこと、車内側脚部12bが剛性を有することにより、脚部12bが閉じにくくなり、フランジ1への差込みに支障を生ずることがなく、仮に多少閉じるようなことがあっても車内側脚部12bは、グリップ12の開口に向かって拡開する傾斜部12cを有するため、該傾斜部12cがガイドとなってフランジ1への差込みが支障なく容易に行えること、保持リップ15がフランジ1に車外側から弾接することにより、車内側脚部12bがフランジ1に車内側から弾接するのと相俟ってグリップ12の保持力が一段と高められ、止水性が向上して車外側からの水の浸入による水洩れをより確実に防ぐことができること等の効果を有する。   According to the weather strip of the present embodiment, the holding force and the sealing force to the flange 1 are increased as described above, the vehicle inner leg portion 12b is hollow, and the weight is reduced by that amount compared to the solid state. Although the vehicle interior leg 12b is hollow, it is thicker and more rigid than the vehicle interior leg 2b of the conventional weatherstrip shown in FIG. 2, and it is deformed to the vehicle interior as described above. 3 is not lifted up from the flange 1 and the wobbling phenomenon as shown in FIG. 3 does not occur, and the inner leg portion 12b has rigidity, so that the leg portion 12b is difficult to close and the flange 1 The inner leg portion 12b has an inclined portion 12c that expands toward the opening of the grip 12 even if it closes somewhat without causing any trouble in insertion. Become The grip 12 can be easily inserted into the flange 1 without hindrance, and the holding lip 15 is elastically contacted with the flange 1 from the outside of the vehicle, so that the vehicle inner leg 12b is elastically contacted with the flange 1 from the inside of the vehicle. The holding power is further enhanced, the water stoppage is improved, and it is possible to more reliably prevent water leakage due to intrusion of water from the outside of the vehicle.
