この考案は自動車のフランジ等の剛体端縁に取
付けられるウエザーストリツプの改良に関するも
のである。[Detailed Description of the Invention] This invention relates to an improvement of a weather strip that is attached to the edge of a rigid body such as a flange of an automobile.
従来のこの種のウエザーストリツプは、第１図
乃至第４図に示される如く、剛体端縁に挟着する
取付部１ａの外脚２ａにおいて、それぞれ１本乃

考案はなされたものである。 Among these, the two-jaw weather strip shown in Figures 1 and 2 is superior in terms of sealing performance, flange insertability, and holding power. This invention was developed in order to provide a weather strip with excellent sealing properties and holding power.
まず第５図に基いてこの考案の実施例を説明す
る。 First, an embodiment of this invention will be explained based on FIG.
１はウエザーストリツプの取付部で、芯金９が
埋設されており、硬質エチレンプロピレンゴム
（EPDM）により断面Ｕ字状に押出成形されてい
る。 Reference numeral 1 denotes a weather strip mounting portion, in which a core bar 9 is embedded, and is extruded from hard ethylene propylene rubber (EPDM) into a U-shaped cross section.
取付部１の外脚２の内側には２条の爪部すなわ
ち開口側爪部３と奥側爪部４とが突設されてい
る。 Two claw parts, namely an opening side claw part 3 and a back side claw part 4, are provided protruding from the inner side of the outer leg 2 of the attachment part 1.
開口側爪部３には断面く字状のエチレンプロピ
レンゴムのスポンジ製シール片５の下端が固着さ
れるいつぽう、奥側爪部４は開口側爪部３よりも
やや丈が低くスポンジ製シール片５の上部５ａと
の間に間隙６を有している。 The lower end of a sponge seal piece 5 made of ethylene propylene rubber with a dogleg-shaped cross section is fixed to the opening side claw part 3, and the back side claw part 4 is slightly shorter in length than the opening side claw part 3 and is a sponge seal. A gap 6 is provided between the piece 5 and the upper part 5a.
また、取付部１の内脚７の内側にも２条の爪部
８が、外脚２の２条の爪部３，４に対応させて突
設されている。 Further, two claw portions 8 are provided protrudingly provided on the inner side of the inner leg 7 of the attachment portion 1 in correspondence with the two claw portions 3 and 4 of the outer leg 2.
なお、外脚２の外側には止水脚１０が設けら
れ、また取付部１の頂部には断面円環状のスポン
ジ製シール部１１が取付けられている。 A water stop leg 10 is provided on the outside of the outer leg 2, and a sponge sealing part 11 having an annular cross section is attached to the top of the mounting part 1.
しかして、第６図及び第７図に示す如く自動車
のパネルの剛体端縁１２にウエザーストリツプの
取付部１を嵌合挟持させたとき、スポンジ製シー
ル片５が剛体端縁１２に圧着状態で上方に引延ば
され上部５ａの背面が奥側爪部４に接触支持され
る。 As shown in FIGS. 6 and 7, when the mounting portion 1 of the weather strip is fitted and held between the rigid edge 12 of the automobile panel, the sponge seal piece 5 is crimped onto the rigid edge 12. In this state, the upper part 5a is stretched upward and the back surface of the upper part 5a is brought into contact with and supported by the rear claw part 4.

の接触面積は従来のものに比べて大きくシール性
が向上する。 In this case, even if there is a dimensional difference in the gap between the outer leg side claws 3, 4 and the inner leg side claws 8, 8 with respect to the rigid end edge 12 due to manufacturing errors, the stretched sponge seal piece 5 Since the inner claw portion 4 presses the back surface toward the rigid end edge 12, excellent sealing performance can be obtained as shown in FIGS. 6 and 7. When a force is applied to the mounting part 1 in the direction of pulling out the mounting part 1 from the rigid edge 12, the bending angle of the doglegged sponge seal piece 5 changes to become larger as shown in FIG. Both the part 3 and the back claw part 4 are deformed in the rising direction, and the back part 4 touches the back surface of the sponge seal piece 5 to the rigid edge 12.
Since the rigid body edge 12 is pressed even more strongly toward
This makes it even more difficult for the attachment part 1 to come off, and the holding force of the attachment part is significantly improved compared to those shown in FIGS. 1 and 2. Moreover, since the rear side of the sponge seal piece 5 which has been stretched out when fitted onto the rigid end edge 12 is pressed against the rigid end edge 12 by the rear claw portion 4, the rigid end of the sponge rubber seal piece 5 The contact area of the pressing part with the edge 12 is larger than that of the conventional one, and the sealing performance is improved.

持される如く構成されたものである。 As mentioned above, this invention is a weather strip having a core metal embedded attachment part 1 with a U-shaped cross section that is clamped to a rigid end edge 12 of a flange or the like.
Two claws 3, 4, 8, 8 are provided on the inside of each of the inner legs 7 and outer legs 2, and a sponge seal with a dogleg-shaped cross section is attached to the claws 3 on the opening side of the outer legs 2. The lower end of the piece 5 is fixed, and there is a gap between the back claw part 4 on the back side of the opening side claw part 3 and the upper part 5a of the sponge sealing piece 5 when it is not clamped with the rigid edge 12. 6, and when it is clamped to the rigid end edge 12, the sponge seal piece 5 is stretched upward, and the upper back surface of the sponge seal piece 5 is in contact with and supported by the outer leg rear claw part 4. It is constructed as follows.
この考案によれば、剛体端縁１２を押込む際、

るので、容易に抜出すことなく、優れた保持力を
維持する。更に接触摩擦力によつてもスポンジ製
シール片５が引延ばされるので剛体端縁１２に対
する接触面積は大きく、シール性がよい。 According to this invention, when pushing the rigid edge 12,
The rigid end edge 12 first comes into contact with the lower part of the sponge sealing piece 5 and deforms the opening side claw part 3 slightly upward.
Next, the sponge seal piece 5 is stretched upward to close the gap 6 and curve the back claw part 4 upward. At this time, the sponge seal piece 5 narrows the width in the thickness direction while stretching the back claw part 4. It is easy to insert because it slides on the contact surface. Furthermore, in response to a force in the direction of pulling out the weather strip, the rear claw portion 4 rises and further presses the sponge rubber sealing piece 5 toward the rigid edge 12, as shown in FIG. Maintains excellent holding power without slipping out. Further, since the sponge seal piece 5 is stretched by the contact friction force, the contact area with the rigid end edge 12 is large, and the sealing performance is good.
また、スポンジ製シール片５の上部５ａと開口
側爪部４との間に設けた間隙６によつて、ソリツ
ドゴムとスポンジゴムとを同時押出し成形すると

出来る。 In addition, the gap 6 provided between the upper part 5a of the sponge sealing piece 5 and the opening-side claw 4 allows the tip of the opening-side claw 4 to The seal piece upper part 5a can be manufactured with relatively high precision dimensions.
そして、本考案においては、スポンジ製シール

向する２つの爪部８，８との計４点で剛体端縁１

が出来る。 In the present invention, the sponge seal piece 5 contacts the rigid edge 12 at two points, and also contacts the rigid edge 12 at four points in total, including the two opposing claws 8, 8.
2, it can be installed very stably.

ている。 Furthermore, according to this invention, the sponge seal piece 5 is supported and crimped onto the rigid edge 12 by the two claws 3 and 4, unlike the conventional case shown in FIGS. 1 to 4. Compared to a case where all the claws 13 are made of sponge, the sealing performance is more reliable and the holding force to the rigid edge 12 is improved.
