Japanese Patent Laying-Open No. 2005-306344

特許文献１に記載のウエルトでは、上記押込部とウエルト本体の他方の側壁との間にフランジ部を保持するようになっているため、フランジ部からの引き抜き方向の力がウエルトに作用したときに、押込部とともにフランジ部がウエルト本体から抜け出てしまう虞があった。   In the welt described in Patent Document 1, since the flange portion is held between the pushing portion and the other side wall of the welt body, when the force in the pulling direction from the flange portion acts on the welt. There was a possibility that the flange part would come out of the welt body together with the pushing part.

本発明は、このような課題に鑑みてなされたものであって、フランジ部への装着時に押込部のウエルト本体からの離脱を防止することで、フランジ部に対する保持力を向上させたウエルトを提供することを目的としている。   The present invention has been made in view of such a problem, and provides a welt having improved holding force with respect to the flange portion by preventing the pushing portion from being detached from the welt body when the flange portion is mounted. The purpose is to do.

請求項１に記載の発明は、樹脂製の芯材を埋設した断面略Ｕ字状のウエルト本体と、そのウエルト本体の両側壁のうち少なくとも一方の側壁の先端部からウエルト本体の外部側へ片持ち状態で延出する押込部と、を有し、その押込部をウエルト本体の内部側に押し込んだ状態で自動車のフランジ部に装着されるウエルトにおいて、上記ウエルト本体のうち押込部が延出する側壁の内面側に芯材が露出していて、その芯材の露出面の略全面にわたってウエルト本体の長手方向に延びる凹状または凸状の係止部が並列に複数形成されている一方、フランジ部装着状態で上記係止部と嵌合する被係止部を上記側壁の内面に合致する形状をもって上記押込部に形成してあり、上記押込部のうち上記側壁先端と上記被係止部とを接続する根本部に形成されている屈曲容易部を支点として上記押込部をウエルト本体の内部側に折り込み、上記根本部のうち屈曲容易部よりも上記側壁側の部位と屈曲容易部よりも上記被係止部側の部位とを密着させたときに、上記芯材の露出面に対し被係止部が全面密着のかたちで重なり合って、当該被係止部が係止部に嵌合するようになっていることを特徴としている。 According to the first aspect of the present invention, there is provided a welt body having a substantially U-shaped cross section in which a resin core material is embedded, and a piece extending from the tip of at least one of the side walls of the welt body to the outside of the welt body. has a push portion extending canti state, and in the welt being attached to the pushing part to the flange portion of the motor vehicle in a state pushed to the inner side of the welt body, indentation out of the welt body extends While the core material is exposed on the inner surface side of the side wall, a plurality of concave or convex engaging portions extending in the longitudinal direction of the welt body are formed in parallel over substantially the entire exposed surface of the core material, while the flange portion A locked portion that fits with the locking portion in a mounted state is formed on the pushing portion with a shape that matches the inner surface of the side wall, and the side wall tip and the locked portion of the pushing portion are Formed at the base to connect The pushing portion is folded into the inner side of the welt body with the easily bendable portion as a fulcrum, and the portion of the root portion that is closer to the side wall than the easily bendable portion and the portion that is closer to the locked portion than the easily bendable portion When the contact portion is brought into close contact with the exposed surface of the core material, the locked portion overlaps with the entire surface so that the locked portion fits into the locking portion. Yes.

したがって、この請求項１に記載の発明では、フランジ部装着状態で上記係止部と被係止部とが係合し、上記被係止部がウエルト本体からの離脱方向で上記係止部と引っ掛かりの関係になるから、この引っ掛かりをもって押込部のウエルト本体からの離脱が防止される。   Therefore, in the invention according to the first aspect, the locking portion and the locked portion are engaged with each other when the flange portion is mounted, and the locked portion is separated from the locking portion in the direction away from the welt body. Since it is in the relationship of being caught, the detachment of the pushing portion from the welt body is prevented by this catch.

その上、上記係止部が上記側壁内面の略全面にわたって並列に複数設けられている一方、上記被係止部が上記側壁の内面に合致する形状に形成されているので、フランジ部装着状態で上記押込部をウエルト本体に対してより効果的に係止できる。 Thereon, while the upper Symbol locking part is provided with a plurality in parallel across substantially the entire surface of the side wall inner surface, so the the engaged portion is formed in a shape that matches the inner surface of the side wall, flange mounted state Thus, the pushing portion can be more effectively locked to the welt body.

また、ウエルト本体のうち上記押込部が延出する側壁の内面側に芯材が露出していて、その芯材に上記係止部が形成されているので、比較的硬質な芯材に上記係止部を形成することにより、フランジ部からの引き抜き方向の力がウエルトに作用したときに、上記係止部が変形しにくくなる。 In addition, since the core material is exposed on the inner surface side of the side wall of the welt body from which the pushing portion extends, and the locking portion is formed on the core material, the engagement is performed on the relatively hard core material. By forming the stop portion, when the force in the pulling direction from the flange portion acts on the welt, the locking portion is hardly deformed.

さらに、上記押込部のうち上記側壁先端と上記被係止部とを接続する根本部に屈曲容易部が形成されていて、その屈曲容易部を支点として上記押込部をウエルト本体の内部側に折り込み、上記根本部のうち屈曲容易部よりも上記側壁側の部位と屈曲容易部よりも上記被係止部側の部位とを密着させたときに、上記芯材の露出面に対し被係止部が全面密着のかたちで重なり合って、当該被係止部が係止部に嵌合するようになっているので、屈曲容易部を支点として上記押込部をウエルト本体の内部側に折り込むことで、上記係止部と被係止部とを容易に相対位置決めできるようになる。Further, an easy-bending portion is formed at the root portion connecting the tip of the side wall and the locked portion of the pushing portion, and the pushing portion is folded into the inner side of the welt body with the easy-bending portion as a fulcrum. When the portion of the base portion closer to the side wall than the easily bendable portion and the portion closer to the locked portion than the easily bendable portion are brought into close contact with each other, the locked portion with respect to the exposed surface of the core member Are overlapped in the form of close contact with each other, and the locked portion is adapted to fit into the locking portion.By folding the pushing portion into the inner side of the welt body with the easy bending portion as a fulcrum, The locking portion and the locked portion can be easily positioned relative to each other.

より望ましくは請求項２に記載の発明のように、上記被係止部が、上記押込部のうちフランジ部との当接部を構成する材料よりも硬質な材料で形成されていると、フランジ部からの引き抜き方向の力がウエルトに作用したときに、上記被係止部が変形しにくくなる。More preferably, as in the invention described in claim 2, when the locked portion is formed of a material harder than a material constituting a contact portion with the flange portion of the pushing portion, a flange is formed. When the force in the pulling direction from the portion acts on the welt, the locked portion becomes difficult to deform.

少なくとも請求項１に記載の発明によれば、上記押込部をウエルト本体の内部に押し込んだ状態でフランジ部に装着すると、上記押込部がウエルト本体からの離脱方向で当該ウエルト本体に対して係止され、その押込部のウエルト本体からの離脱が防止されるため、フランジ部に対する保持力が向上する効果がある。   According to at least the first aspect of the present invention, when the pressing portion is attached to the flange portion while being pressed into the interior of the welt body, the pressing portion is locked to the welt body in a direction away from the welt body. In addition, since the detachment of the pushing portion from the welt body is prevented, there is an effect that the holding force with respect to the flange portion is improved.

また、フランジ部からの引き抜き方向の力がウエルトに作用したときに、上記被係止部または係止部が変形しにくくなるため、フランジ部に対する保持力をさらに向上させることができる。 Further, when the force in the pulling direction from the flange portion acts on the welt, the locked portion or the locking portion is not easily deformed, so that the holding force for the flange portion can be further improved.

さらに、屈曲容易部を支点として上記押込部をウエルト本体の内部側に折り込むことで、上記係止部と被係止部とを容易に相対位置決めできるため、フランジ部への取付作業性が向上するメリットがある。
 Furthermore, since the pushing portion is folded into the inner side of the welt body with the bendable portion as a fulcrum, the locking portion and the locked portion can be easily relatively positioned, thereby improving the workability of mounting to the flange portion. There are benefits.

図１は本発明のより具体的な実施の形態を示す図であって、本発明にかかるウエルトを有するウェザーストリップの断面図である。   FIG. 1 is a view showing a more specific embodiment of the present invention, and is a cross-sectional view of a weather strip having a welt according to the present invention.

図１に示すウェザーストリップ１は、図示外の自動車のドア開口縁部に沿って形成された後述するフランジ部に装着される長尺状のものであって、そのフランジ部に組み付く取付基部となるウエルト２と、そのウエルト２のうち後述するウエルト本体５の外壁５ａの外面側に膨出し、自動車のドア外周縁部に弾接することになる中空シール３と、ウエルト２のうち後述するウエルト本体５の底壁５ｃ外面を覆いつつその底壁５ｃから反中空シール３側に延出し、その先端が自動車の内装材に弾接することになるカバーリップ４と、を備えている。なお、中空シール３は、スポンジゴムもしくは比較的軟質なＴＰＯ等のエラストマーをもって形成され、その外面および内面にそれぞれ滑性膜３ａが形成されている一方、カバーリップ４は、中空シール３よりも硬質なソリッドゴムもしくはＴＰＯ等のエラストマーをもって形成され、その表面に装飾のための着色滑性膜４ａが形成されている。   A weatherstrip 1 shown in FIG. 1 is a long one that is attached to a flange portion, which will be described later, formed along a door opening edge of an automobile (not shown), and an attachment base portion that is assembled to the flange portion. Of the welt 2, a hollow seal 3 that bulges to the outer surface side of the outer wall 5 a of the welt body 5, which will be described later, and elastically contacts the outer periphery of the door of the automobile, and a welt body, which will be described later, of the welt 2. The cover lip 4 extends from the bottom wall 5c to the anti-hollow seal 3 while covering the outer surface of the bottom wall 5c, and the tip of the cover lip 4 elastically contacts the interior material of the automobile. The hollow seal 3 is formed of a sponge rubber or a relatively soft elastomer such as TPO, and a slipping film 3a is formed on each of the outer surface and the inner surface thereof, while the cover lip 4 is harder than the hollow seal 3. It is made of a solid rubber or an elastomer such as TPO, and a colored slipping film 4a for decoration is formed on the surface thereof.

そして、ウエルト２は、比較的硬質な樹脂からなる芯材６が埋設された断面略Ｕ字状のウエルト本体５と、そのウエルト本体５のうち車外側の側壁である外壁５ａの先端からウエルト本体５の外部側に向けて延出する押込部としての保持リップ８と、ウエルト本体５のうち車内側の側壁である内壁５ｂからウエルト本体５の内部側に延出するインナリップ９と、ウエルト本体５の内壁５ｂ先端から突出する突出部１０と、を備えている。なお、インナリップ９および突出部１０はカバーリップ４と同様の材料から形成されているとともに、突出部１０の表面からインナリップ９の根本部表面にかけて滑性膜１０ａが形成されている。   The welt 2 includes a welt body 5 having a substantially U-shaped cross-section in which a core material 6 made of a relatively hard resin is embedded, and a welt body from the front end of the outer wall 5a which is a side wall on the vehicle outer side of the welt body 5. A holding lip 8 as a pushing portion extending toward the outer side of the inner wall 5, an inner lip 9 extending from the inner wall 5b of the welt body 5 to the inner side of the welt body 5, and a welt body 5 and a protruding portion 10 protruding from the tip of the inner wall 5b. The inner lip 9 and the protruding portion 10 are formed of the same material as the cover lip 4, and a slipping film 10 a is formed from the surface of the protruding portion 10 to the surface of the root portion of the inner lip 9.

また、ウエルト本体５のうち断面略Ｕ字状の芯材６は、当該芯材６よりも軟質であって且つカバーリップ４よりも硬質なソリッドゴムまたはＴＰＯ等のエラストマーからなる被覆体７によって被覆されている。   Further, the core material 6 having a substantially U-shaped cross section in the welt body 5 is covered with a cover 7 made of solid rubber or elastomer such as TPO that is softer than the core material 6 and harder than the cover lip 4. Has been.

さらに、ウエルト本体５のうち外壁５ａの内面には、被覆体７の開口によって芯材６が露出しており、その芯材６の露出部分に、ウエルト本体５の長手方向に延びる係止部たる係合溝１１が、外壁５ａ内面の略全面にわたって並列に複数凹設されている。より詳細には、各係合溝１１は断面略鋸歯状をなしていて、ウエルト本体５の底壁５ｃ側を向いた平面部１１ａを有している。   Furthermore, the core material 6 is exposed on the inner surface of the outer wall 5 a of the welt body 5 through the opening of the covering body 7, and the exposed portion of the core material 6 is a locking portion extending in the longitudinal direction of the welt body 5. A plurality of engaging grooves 11 are provided in parallel over substantially the entire inner surface of the outer wall 5a. More specifically, each engagement groove 11 has a substantially serrated cross section, and has a flat portion 11a facing the bottom wall 5c side of the welt body 5.

一方、保持リップ８は、断面略Ｌ字状に屈曲しながら反中空シール３側を指向しており、その保持リップ８の先端部に、被覆体７と同様の材料をもって形成された被係止部１２が設けられている。この被係止部１２には、ウエルト本体５の長手方向に延びる断面略鋸歯状の爪部１４が各係合溝１１に対応して並列に複数突設されており、これによって被係止部１２のうちウエルト本体５側を向いた面が外壁５ａの内面と合致する形状をなしている。   On the other hand, the holding lip 8 is directed to the anti-hollow seal 3 side while being bent in a substantially L-shaped cross section, and is engaged at the tip of the holding lip 8 with the same material as the covering 7. A portion 12 is provided. A plurality of claw portions 14 having a substantially serrated cross section extending in the longitudinal direction of the welt body 5 are provided on the locked portion 12 so as to protrude in parallel corresponding to the respective engaging grooves 11. 12, the surface facing the welt body 5 side is shaped to match the inner surface of the outer wall 5a.

また、被係止部１２の根本部および先端部の背面側には、ウエルト２を後述するフランジ部に装着したときにそのフランジ部と当接する当接部としての突条部１３がそれぞれ突設されていて、この両突条部１３はカバーリップ４と同様の材料、すなわち、被係止部１２よりも軟質な材料をもって形成されている。   In addition, on the back side of the root portion and the tip portion of the locked portion 12, a protruding portion 13 is provided as a contact portion that comes into contact with the flange portion when the welt 2 is mounted on a flange portion described later. In addition, both the protrusions 13 are formed of the same material as that of the cover lip 4, that is, a material softer than the locked portion 12.

さらに、保持リップ８のうち断面略Ｌ字状をなす根本部８ａは、そのコーナー部分に一般部よりも肉薄な屈曲容易部８ｂが形成されている。これにより、その屈曲容易部８ｂを支点として被係止部１２をウエルト本体５の内部側へ容易に折り込むことができるようになっている。なお、保持リップ８の根本部８ａはカバーリップ４と同様の材料をもって形成されていて、その根本部８ａの表面には滑性膜８ｃが形成されている。   Further, the base portion 8a having a substantially L-shaped cross section in the holding lip 8 is formed with an easily bendable portion 8b thinner at the corner portion than the general portion. Thus, the locked portion 12 can be easily folded into the inner side of the welt body 5 with the bendable portion 8b as a fulcrum. The root portion 8a of the holding lip 8 is formed of the same material as that of the cover lip 4, and a slipping film 8c is formed on the surface of the root portion 8a.

図２は、図１に示すウェザーストリップ１を自動車のフランジ部に装着するときの状態を示す断面図である。   FIG. 2 is a cross-sectional view showing a state when the weather strip 1 shown in FIG. 1 is mounted on a flange portion of an automobile.

以上のように構成したウエルト２は、図２に示すように、屈曲容易部８ｂを支点として被係止部１２ををウエルト本体５の内部側に折り込んで当該被係止部１２をウエルト本体５の内側に押し込み、根本部８ａのうち屈曲容易部８ｂよりも外壁５ａ側の部位と屈曲容易部８ｂよりも被係止部１２側の部位とを密着させると、被係止部１２が各係止溝１１に対して相対位置決めされ、各係止溝１１と各爪部１４がそれぞれ嵌合することになる。   As shown in FIG. 2, the welt 2 configured as described above is configured such that the locked portion 12 is folded inside the welt body 5 with the bendable portion 8 b as a fulcrum, and the locked portion 12 is folded into the welt body 5. When the portion of the root portion 8a that is closer to the outer wall 5a than the easily bendable portion 8b and the portion that is closer to the locked portion 12 than the easily bendable portion 8b are brought into close contact with each other, Relative positioning is performed with respect to the stop groove 11, and each locking groove 11 and each claw portion 14 are fitted.

そして、このように各係止溝１１と各爪部１４がそれぞれ嵌合した状態で、保持リップ８の両突条部１３とインナリップ９をそれぞれ保持部として両者の間に車体側のフランジ部１５が挟持されることになる。   And in the state which each latching groove | channel 11 and each nail | claw part 14 each fitted in this way, both the rib parts 13 of the holding lip 8 and the inner lip 9 are made into the holding part, respectively, and the flange part by the side of a vehicle body between both 15 will be pinched.

なお、このように各係止溝１１と各爪部１４がそれぞれ嵌合した状態では、保持リップ８の両突条部１３とインナリップ９との間の隙間がフランジ部１５の厚みよりも狭くなるように設定されており、ウエルト２をフランジ部１５に装着すると、インナリップ９のリップ反力によって被係止部１２がウエルト本体５の外壁５ａに押しつけられるようになっている。   In addition, in a state where the respective locking grooves 11 and the respective claw portions 14 are respectively fitted in this way, the gap between the both ridge portions 13 of the holding lip 8 and the inner lip 9 is narrower than the thickness of the flange portion 15. When the welt 2 is mounted on the flange portion 15, the locked portion 12 is pressed against the outer wall 5 a of the welt body 5 by the lip reaction force of the inner lip 9.

このようにウエルト２をフランジ部１５に装着すると、被係止部１２が外壁５ａに密着しつつ各爪部１４が各係止溝１１にそれぞれ嵌合するから、各係止溝１１の平面部１１ａと各爪部１４の平面部１４ａとの引っ掛かりにより、被係止部１２がウエルト本体５の高さ方向、すなわちウエルト本体５からの離脱方向で当該ウエルト本体５に対して係止される。   When the welt 2 is attached to the flange portion 15 in this manner, the claw portions 14 are fitted into the respective locking grooves 11 while the locked portion 12 is in close contact with the outer wall 5a. By being hooked between 11a and the flat surface portion 14a of each claw portion 14, the locked portion 12 is locked to the welt body 5 in the height direction of the welt body 5, that is, in the direction away from the welt body 5.

したがって、本実施の形態によれば、ウエルト２をフランジ部１７に装着したときに、各係止溝１１と各爪部１４との嵌合によって被係止部１２がウエルト本体５に対して係止され、その被係止部１２のウエルト本体５からの離脱が防止されるから、ウエルト２のフランジ部１７に対する保持力が向上する。   Therefore, according to the present embodiment, when the welt 2 is mounted on the flange portion 17, the locked portion 12 is engaged with the welt body 5 by the fitting of the respective locking grooves 11 and the respective claw portions 14. Since it is stopped and the detachment of the locked portion 12 from the welt body 5 is prevented, the holding force for the flange portion 17 of the welt 2 is improved.

その上、比較的硬質な芯材６に各係止溝１１を形成しているため、フランジ部１５からの引き抜き方向の力がウエルト５に作用したときに、各係止溝１１が変形しにくくなり、被係止部１２のウエルト本体５からの離脱をより確実に防止できる。   In addition, since each locking groove 11 is formed in the relatively hard core 6, each locking groove 11 is not easily deformed when a force in the pulling direction from the flange portion 15 acts on the welt 5. Thus, the detachment of the locked portion 12 from the welt body 5 can be prevented more reliably.

さらに、被係止部１２を突条部１３よりも硬質な材料で形成しているため、フランジ部１５からの引き抜き方向の力がウエルト５に作用したときに、各爪部１４が変形しにくいばかりでなく、被係止部１２が波打つように湾曲変形することも抑制できるから、被係止部１２のウエルト本体５からの離脱をさらに確実に防止できるメリットがある。   Further, since the locked portion 12 is formed of a material harder than the protruding portion 13, each claw portion 14 is not easily deformed when a pulling direction force from the flange portion 15 acts on the welt 5. In addition, since it is possible to prevent the locked portion 12 from being bent and deformed so as to wave, there is an advantage that the locked portion 12 can be more reliably prevented from being detached from the welt body 5.

また、屈曲容易部８ｂを支点として被係止部１２をウエルト本体５の内部側に折り込むことで、被係止部１２を各係止溝１１に対して容易に相対位置決めできるようになっているため、ウエルト５のフランジ部１５への取付作業が容易になるメリットがある。   Further, the locked portion 12 can be easily positioned relative to each locking groove 11 by folding the locked portion 12 into the inner side of the welt body 5 with the bendable portion 8b as a fulcrum. Therefore, there is an advantage that the attachment work of the welt 5 to the flange portion 15 becomes easy.

なお、本実施の形態では、ウエルト本体５の外壁５ａに係止溝１１を、保持リップ８の被係止部１２に爪部１４をそれぞれ設けたが、ウエルト本体５の外壁５ａに爪部を、保持リップ８の被係止部１２に係止溝をそれぞれ設けてもよいことは言うまでもない。   In the present embodiment, the locking groove 11 is provided on the outer wall 5a of the welt body 5 and the claw portion 14 is provided on the locked portion 12 of the holding lip 8. However, the claw portion is provided on the outer wall 5a of the welt body 5. Needless to say, a locking groove may be provided in each of the locked portions 12 of the holding lip 8.

また、本実施の形態では、各係止溝１１および各爪部１４をそれぞれ断面略鋸歯状に形成したが、各係止溝および各爪部の断面形状はこれに限定されるものではなく、ウエルト２のフランジ部１５への装着時に被係止部１２のウエルト本体５からの離脱方向で各爪部が各溝部に対して引っ掛かりの関係になればよい。   Further, in the present embodiment, each locking groove 11 and each claw portion 14 are formed in a substantially serrated cross section, but the cross-sectional shape of each locking groove and each claw portion is not limited to this, It is only necessary that each claw portion is hooked to each groove portion in the direction in which the locked portion 12 is detached from the welt body 5 when the welt 2 is attached to the flange portion 15.
