Description

【０００１】
【発明の属する技術分野】
本発明は、自動車のドアにクリップで取付けられるドアウエザーストリップに関するものである。
【０００２】
【従来の技術】
図１乃至図３を参照して説明する。従来、押出成形部Ｅと型成形部Ｍとからなり、自動車のドア１にクリップ４で取付けられるドアウエザーストリップ３０において、その押出成形部Ｅの基底部３１下面に比重０．１〜０．３程度で高発泡スポンジ製のサブシール３２を一体押出成形したものがある。
【０００３】
このドアウエザーストリップ３０は、押出成形部Ｅの端部を金型内に挿入し、それを当該金型内で成形する型成形部Ｍに連設するのであるが、金型内で前記サブシール３２に連続する高発泡スポンジを一体成形することができない等の理由から当該金型内で潰していた。そして、型成形後、型成形部Ｍのサブシール３２から連続する部分に、高発泡連続気泡スポンジ製の高発泡シール材２０を貼り付け、潜り水Ｗの発生を防止していた。
【０００４】
しかし、高発泡シール材２０とサブシール３２との間から潜り水Ｗが発生しないようにするために、高発泡シール材２０の端部をサブシール３２の端部に重ね合わせた状態で正確に貼付けなければならない。そのため、貼付け方にバラツキが生じた場合には隙間が形成されてしまい、そこから潜り水Ｗが発生する。また、それを防止するためには、貼付け作業を慎重に行う必要があるので、必然的に作業性が低下する。
【０００５】
本発明はこうした問題に鑑み創案されたもので、押出成形部と型成形部Ｍとの間部分から潜り水が発生せず、また、高発泡シール材を貼付ける場合でも作業性を低下させることのない自動車用ドアウエザーストリップを提供することを課題とする。
【０００６】
【課題を解決するための手段】
第一の発明に係る自動車用ドアウエザーストリップ１０は、自動車のドア１に全周にわたってクリップ４で取付けられ、押出成形部Ｅの基底部１１下面に、ドア枠部２の取付面３に密接する高発泡スポンジ製のサブシール１２を一体成形したドアウエザーストリップにおいて、前記押出成形部Ｅの基底部１１下面の前記サブシール１２に隣接する車内側３３で、かつ、前記クリップで固定する位置よりも車外側３４に、前記取付面３に密接する押出部突条１３を一体成形すると共に、前記押出成形部Ｅに接続される型成形部Ｍの基底部１１下面に、前記押出部突条１３に一体的に連続し前記取付面３に密接する型部突条１４を一体成形してなるものである。
【０００７】
第二の発明に係る自動車用ドアウエザーストリップ１０は、自動車のドア１に全周にわたってクリップ４で取付けられ、押出成形部Ｅの基底部１１下面に、ドア枠部２の取付面３に密接する高発泡スポンジ製のサブシール１２を一体成形したドアウエザーストリップにおいて、前記押出成形部Ｅの基底部１１下面の前記サブシール１２に隣接する車内側３３で、かつ、前記クリップで固定する位置よりも車外側３４に、前記取付面３に密接する押出部突条１３を一体成形すると共に、前記押出成形部Ｅに接続される型成形部Ｍの基底部１１下面に、前記押出部突条１３に一体的に連続し前記取付面３に密接する型部突条１４を一体成形し、前記型成形部Ｍの基底部１１下面の前記型部突条１４より車外側３４に、または、前記型部突条１４より車外側３４の前記押出成形部Ｅのサブシール１２に連続する部分に、前記取付面３に密接する高発泡シール材２０を貼付けてなるものである。
【０００８】
【発明の実施の形態】
本発明に係る自動車用ドアウエザーストリップ１０の実施形態を、図１および図４乃至図７に示す。これは、自動車のドア１に全周にわたって複数のクリップ４で取付けられ、押出成形部Ｅの基底部１１下面に、ドア枠部２の取付面３に密接する比重０．１〜０．３程度の高発泡スポンジゴム製のサブシール１２を一体的に押出成形したドアウエザーストリップである。なお、３３は車内側、３４は車外側である。
【０００９】
このドアウエザーストリップ１０は、基底部１１からボディパネル５に弾接する中空シール部１８を有し、その車外側３４にボディパネル５に弾接するシールリップ１５と、ドア枠部２に弾接する上部メインシール１６と下部メインシール１７を備えている。
【００１０】
そして、押出成形部Ｅの基底部１１下面のサブシール１２に隣接する車内側３３に、取付面３に密接する押出部突条１３を一体的に押出成形している。また、押出成形部Ｅに接続される型成形部Ｍの基底部１１下面に、押出部突条１３に一体的に連続し前記取付面３に密接する型部突条１４を一体的に型成形している。
【００１１】
このドアウエザーストリップ１０は、押出成形部Ｅの基底部１１下面に、ドア枠部２の取付面３に密接する押出部突条１３に連続して、型成形部Ｍの基底部１１下面に型部突条１４を形成しているので、この押出部突条１３と型部突条１４が切れることなく連続して取付面３に密接する。従って、型成形部Ｍに、サブシール１２に連続して高発泡シール材２０を貼着しなくても、十分なシール性を確保することができ、潜り水Ｗの発生を未然に防止することができる。また、高発泡シール材２０の使用を省略することができるので、作業性の向上と製造コストの低廉化を図ることができる。
【００１２】
また、押出部突条１３を、押出成形部Ｅのサブシール１２より車内側３３に形成し、型部突条１４を、押出部突条１３に連続して形成しているので、サブシール１２の車外側３４に形成する場合と比較して、当該押出部突条１３と型部突条１４を、クリップ４の近傍に位置させることができる。従って、ドアウエザーストリップ１０をクリップ４で固定した際の押圧力を、当該押出部突条１３と型部突条１４に効果的に伝えることができ、ドア１（取付面３）とのシール性を高めることができる。
【００１３】
なお、この押出部突条１３および型部突条１４と共に、高発泡スポンジ材を、型成形部Ｍの基底部１１下面の型部突条１４より車内側３３に貼付けることができる。また、この高発泡シール材２０を、型部突条１４より車外側３４で、押出成形部Ｅのサブシール１２に連続する部分に貼付けることもできる（図６参照）。この高発泡シール材２０は、比重０．１程度のＥＰＤＭに両面接着テープを接着したエプトシーラー（商品名）で構成することができる。
【００１４】
このいずれの場合においても、押出部突条１３と型部突条１４とによって潜り水Ｗの発生を十分に防止することができるので、この高発泡シール材２０は、従来技術の押出部突条１３および型部突条１４を持たないウエザーストリップ３０のように、必要以上に正確かつ慎重に貼る必要がない。従って、作業性も低下しない。なお、この高発泡シール材２０を貼着することによって、潜り水Ｗの発生をさらに確実に防止することができる。
【００１５】
【発明の効果】
請求項１に記載の発明に係る自動車用ドアウエザーストリップ１０は、押出成形部Ｅの基底部１１下面に、ドア枠部２の取付面３に密接する押出部突条１３に連続して、型成形部Ｍの基底部１１下面に型部突条１４を形成したので、この押出部突条１３と型部突条１４によって十分なシール性を確保することができる。従って、押出成形部Ｅと型成形部Ｍとの接続部分における潜り水Ｗの発生を、未然に防止することができる。また、高発泡シール材２０の使用を省略することができるので、作業性の向上と製造コストの低廉化を図ることができる。
【００１６】
また、押出部突条１３を、押出成形部Ｅのサブシール１２より車内側３３に形成し、型部突条１４を、それに連続して形成しているので、当該押出部突条１３と型部突条１４を、クリップ４の近傍に位置させることができる。従って、ドアウエザーストリップ１０をクリップ４で固定した際の押圧力を、この押出部突条１３と型部突条１４に効果的に伝えることができ、ドア１とのシール性を高めることができる。
【００１７】
請求項２に記載の発明に係る自動車用ドアウエザーストリップ１０は、請求項１に記載の発明の効果と共に、型成形部Ｍの基底部１１下面の型部突条１４より車内側３３に、または、型部突条１４より車外側３４の前記押出成形部Ｅのサブシール１２に連続する部分に、取付面３に密接する高発泡シール材２０を貼付けたので、潜り水Ｗの発生をさらに確実に防止することができる。
【００１８】
また、押出部突条１３と型部突条１４とによって潜り水Ｗの発生を十分に防止することができるので、この高発泡シール材２０は、従来技術のように必要以上に正確に貼る必要がない。従って、作業性も低下しない。
