この発明はウエザーストリツプの製造法の改良
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved method for manufacturing weather strips.
一般に自動車の窓開口部周縁に沿つて取付けら
れる中空状ウエザーストリツプは第１図乃至第３
図に示す如くストレート部分１ａは押し出し成形
されたやや硬めの材料により、またコーナー部分
２ａもしくは端末部分２ａ（以後コーナー部分２
ａは両者を含む）は型形成されたやや軟らかめの
材料によりそれぞれ別個に作られている。 Hollow weather strips, which are generally installed along the periphery of automobile window openings, are shown in Figures 1 to 3.
As shown in the figure, the straight portion 1a is made of extruded slightly harder material, and the corner portion 2a or end portion 2a (hereinafter referred to as corner portion 2) is made of extruded material.
(a includes both) are made separately from molded slightly softer material.
そのため、従来は第４図に示す如く肉厚の薄い
ストレート部分１ａと肉厚の厚いコーナー部分２
ａとが突合わされて接着される場合、コーナー部
分２ａのテーパー部１１が薄肉となるため、この
テーパー部１１を囲む部分が特に軟弱となり使用
したときシール力の不足をもたらした。 Therefore, conventionally, as shown in FIG. 4, a thin straight part 1a and a thick corner part 2
When the tapered portions 11 of the corner portions 2a are butted and bonded, the tapered portions 11 of the corner portions 2a become thin, and the portions surrounding the tapered portions 11 become particularly weak, resulting in insufficient sealing force when used.
また、第５図に示す如く中空状ストレート部分

合部分が特に硬くなるためウエザーストリツプの
窓開口部周縁への取付けが容易でなく、またドア
の閉め力が大きくなるという欠点があつた。 Further, as shown in FIG. 5, after fitting the joining protrusion 2'a of the solid corner part 2a into the joining part of the hollow straight part 1a, apply adhesive 1 to the abutting part.
3 by overlaying and bonding, or by butting and bonding the bonded end surface formed by filling the bonded portion of the straight portion 1a with the pad 14 and the flat bonded end surface of the bonded portion of the corner portion 2a, as shown in Fig. 6. In both cases shown in Figures 5 and 6, the joints become particularly hard, making it difficult to attach the weather strip to the periphery of the window opening, and the closing force of the door becomes large. It had the disadvantage of becoming.
さらに、第７図に示す如くいずれも中空状であ

あつた。 Furthermore, as shown in FIG. 7, although both are hollow, if an end wall 15 is provided at the joint of the corner portion 2a and abutted against the straight portion 1a, a core 16 or The drawback was that the cost was high because a core was required.
この発明は上述の如き従来のウエザーストリツ
プの欠点を解消するためになされたものである。 This invention has been made in order to overcome the drawbacks of the conventional weather strips as described above.
第８図に基いてこの発明の実施例を説明する。
２０はウエザーストリツプのストレート部分で、
ほぼ直線状で且つ中空状に押し出し成形されたや
や硬めの合成ゴムよりなり、接合部２１には垂直
切断した接合端面２２が形成されている。 An embodiment of the present invention will be described based on FIG.
20 is the straight part of the weather strip,
It is made of slightly hard synthetic rubber extruded into a substantially linear and hollow shape, and the joint portion 21 is formed with a vertically cut joint end face 22 .

差を有した内周端面２７とが形成されている。 23 is the corner part or end part of the weather strip (hereinafter, the corner part 23 includes both)
The joint ridge 26 is made of a slightly soft sponge-like synthetic rubber molded into a hollow shape, and the joint 24 has a joint end surface 25 that comes into contact with the joint end surface 22. An inner circumferential end surface 27 having a step is formed on the inner circumference of the inner circumferential surface 26 .
次に、ストレート部分２０とコーナー部分２３

入用長孔３０より挿入する。 Next, the straight part 20 and the corner part 23
In order to join at both joint parts 21 and 24,
First, the cylindrical pad 29 is fitted into the L-shaped molding core 28 shown by the phantom line, and then inserted together with the cylindrical pad 29 through the long insertion hole 30 provided on the mounting surface of the corner portion 23.
そして、ストレート部分２０の接合部２１とコ
ーナー部分２３の接合突縁部２６が突合せられ、
筒状パツド２９は接合部２１及び接合突縁部２６

９の端面はコーナー部分２３の内周端面２７と接
合する。 Then, the joint portion 21 of the straight portion 20 and the joint ridge portion 26 of the corner portion 23 are butted,
The cylindrical pad 29 has a joint portion 21 and a joint protrusion 26.
The cylindrical pad 2 is fitted onto the inner circumference of the pad so as to straddle both sides.
The end surface of 9 is joined to the inner peripheral end surface 27 of the corner portion 23.
その後、コーナー部分２３の接合部２４は加熱
加硫成形されたのち型成形用中子２８は長孔３０
を経て取除かれる。 Thereafter, the joint portion 24 of the corner portion 23 is heated and vulcanized, and the molding core 28 is formed into the elongated hole 30.
It is removed after

され、加硫成形後の変形も減少する。 As described above, the method for manufacturing a weather strip according to the present invention includes extrusion-molded, slightly hard straight portion 20 of a hollow weather strip that is attached along the periphery of a window opening of an automobile.
In the method of bonding a slightly softer corner part or end part formed by molding, a joining end surface 22 is formed by cutting perpendicularly to the joining part 21 of the straight part 20, and a joining part 24 of the other corner part or end part is bonded. A joint protrusion 26 having a joint end surface 25 that contacts the joint end surface 22 of the straight portion 20 and an inner circumferential end surface 27 having a step on the inner circumference of the joint protrusion 26 are formed, and then a molding medium is formed. Child 2
Connect one end of the cylindrical pad 29 fitted to the joint protrusion 2
After fitting into the inner circumference of 6, the straight part 2
0 and the joint protrusion 26 of the corner portion or end portion, and the other end of the cylindrical pad 29 is brought into contact with the joint portion 2 of the straight portion 20.
1, the cylindrical pad 29 is connected to the joint part 21 of the straight part 20 and the joint protrusion 26.
The joints 24 at the corner portions or end portions are then vulcanized and molded. According to the invention, the straight portion 20 and the corner portion 23
The sudden change in the hardness difference at the joint with the material is alleviated, and the deformation after vulcanization is also reduced.
また、該接合部分の肉厚が全体的に厚くなるた
め使用時のシール力が向上する。 Furthermore, since the thickness of the joint portion is increased overall, the sealing force during use is improved.
さらに、金型の内面に対する中子の位置変動に
よる肉厚のバラツキも少なく、型成形されたコー
ナー部分２３からのオーバーラツプ防止及びスポ
ンジの縮みによる接着段差も減少してシール性が
向上する。 Further, there is little variation in wall thickness due to positional changes of the core relative to the inner surface of the mold, and sealing performance is improved by preventing overlapping from the molded corner portion 23 and by reducing adhesion steps due to shrinkage of the sponge.
またさらに、加硫成形後の中子の取り出しが容
易となるという特長がある。 A further advantage is that the core can be easily removed after vulcanization molding.
