【０００１】
【発明の属する技術分野】
本発明は、例えば車両用のボデーパネルの開口部を閉塞する装着作業性に優れた閉塞栓に関する。
【０００２】
【従来の技術】
この種のゴム製の閉塞栓として、図４〜図６に示すものが知られている。この閉塞栓１は、図４，図６に示すように、車両用のボデーパネル（被閉塞部材）７の表面７ａ側に当接する平面楕円形で環鍔状の栓本体２と、この栓本体２の内周下側より下方に向けて一体突出形成され、外周面３ｂに一体突出形成された係止部３ｃがボデーパネル７の楕円形の開口部８に係止される環状の周壁部３と、この環状の周壁部３の下端間内に一体形成されてボデーパネル７の開口部８を閉塞するように該ボデーパネル７の裏面７ｂ側に突出する押し壁を兼ねた底壁部４とを備えている。
【０００３】
この閉塞栓１の底壁部４の表面４ａの略中央には、ボデーパネル７の開口部８への装着時に押圧される操作部５を一体突出形成してある。また、閉塞栓１の周壁部３の内周面３ａの栓本体２の内周端と底壁部４の外周端との間には、該底壁部４を支持して補強する補強リブ６を所定間隔毎に複数それぞれ一体突出形成してある。
【０００４】
そして、ゴム製の閉塞栓１の操作部５の上面が押し面５ａとなっていて、該押し面５ａを作業者が指９で押圧することにより、閉塞栓１がボデーパネル７の開口部８に装着されて該開口部８が閉塞されるようになっている。即ち、図５に示すように、閉塞栓１の操作部５の押し面５ａをボデーパネル７の裏面７ｂ側に指９で押圧すると、底壁部４が湾曲状に弾性変形する。これにより、ボデーパネル７の開口部８の手前側にある周壁部３の環状の係止部３ｃの外径が縮径され、該係止部３ｃが開口部８を乗り越えて挿通されてボデーパネル７の裏面７ｂ側に係止される。
【０００５】
尚、この閉塞栓１に関する類似技術は、特開平１０−３５６９７号公報に開示されている。
【０００６】
【発明が解決しようとする課題】
しかしながら、前記従来のゴム製の閉塞栓１では、底壁部４の表面４ａ上の操作部５と各補強リブ６との間が離れているため、閉塞栓１をボデーパネル７の開口部８に装着する時に、図５に示すように、操作部５と各補強リブ６との間Ｓの底壁部４が延びて、操作部５の押し面５ａを指９で押す力が逃げてしまい、閉塞栓１のボデーパネル７の開口部８への装着作業性が悪かった。
【０００７】
そこで、本発明は、前記した課題を解決すべくなされたものであり、被閉塞部材の開口部への装着作業性を向上させることができる閉塞栓を提供することを目的とする。
【０００８】
【課題を解決するための手段】
請求項１の発明は、被閉塞部材の表面側に当接する環鍔状の栓本体と、この栓本体の内周下側より下方に向けて一体突出形成され、外周面に形成された係止部が前記被閉塞部材の開口部に係止される環状の周壁部と、この環状の周壁部の下端間内に一体形成されて前記被閉塞部材の開口部を閉塞するように該被閉塞部材の裏面側に突出する押し壁を兼ねた底壁部とを備え、この底壁部の表面の略中央に前記被閉塞部材の開口部への装着時に押圧される操作部を一体突出形成すると共に、前記周壁部の内周面の前記栓本体の内周端と前記底壁部の外周端との間に該底壁部を支持して補強する補強リブを所定間隔毎に複数それぞれ一体突出形成した閉塞栓において、前記操作部の外周面の下端と前記各補強リブの下端とを連結リブで一体的にそれぞれ連結したことを特徴とする。
【０００９】
この閉塞栓では、操作部の外周面の下端と前記各補強リブの下端とを連結リブで一体的にそれぞれ連結したので、閉塞栓を被閉塞部材の開口部に装着する時に、操作部による押圧力が各連結リブを介して各補強リブ（即ち周壁部及び栓本体側）に直接作用し、閉塞栓の被閉塞部材の開口部への装着作業性が向上する。
【００１０】
請求項２の発明は、請求項１記載の閉塞栓であって、前記操作部を略円柱状に一体突出形成し、この略円柱状の操作部の外周面の下端と前記各補強リブの傾斜面の下端とを前記連結リブで一体的にそれぞれ連結したことを特徴とする。また、請求項３の発明は、請求項１記載の閉塞栓であって、前記操作部が前記栓本体の表面より下方に位置していることを特徴とし、さらに、請求項４の発明は、請求項２又は請求項３記載の閉塞栓であって、前記補強リブが略三角板状であることを特徴とする。
【００１１】
この閉塞栓では、各連結リブで略円柱状の操作部の外周面の下端と各補強リブの傾斜面の下端とを一体的にそれぞれ連結したので、閉塞栓を被閉塞部材の開口部に装着する時に、略円柱状の操作部による押圧力が各連結リブを介して各補強リブ（即ち周壁部及び栓本体側）に直接かつ効率良く作用し、略円柱状の操作部と各補強リブ間の底壁部が従来のように延びることがなくなり、閉塞栓の被閉塞部材の開口部への装着作業性がより一段と向上する。特に、操作部が栓本体の表面より下方に位置しているため、被閉塞部材の開口部への閉塞栓の装着時にその縮径を妨げることがなく、被閉塞部材からの反力が少なく装着し易くなる。
【００１２】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。
【００１３】
図１は本発明の一実施形態のゴム製の閉塞栓を示す平面図、図２は図１中Ａ−Ａ線に沿う断面図、図３は同閉塞栓を被閉塞部材としての車両用のボデーパネルの開口部に装着する途中の状態を示す断面図である。
【００１４】
図１〜図３に示すように、ゴム製の閉塞栓１０は、裏面１１ｂが車両用のボデーパネル（被閉塞部材）１７の表面１７ａ側に当接する平面円形で環鍔状の栓本体１１と、この栓本体１１の内周下側より下方に向けて一体突出形成され、外周面１２ｂに一体突出形成された断面略三角形状の係止部１２ｃがボデーパネル１７の円形の開口部１８の開口縁に係止される環状の周壁部１２と、この環状の周壁部１２の下端間内に一体形成されてボデーパネル１７の開口部１８を閉塞するように該ボデーパネル１７の裏面１７ｂ側に突出する押し壁を兼ねた底壁部１３とを備えている。
【００１５】
この栓本体１１の裏面１１ｂは逆円錐面状になって外周側が下方に突出している。また、周壁部１２の内周面１２ａの栓本体１１の内周端と底壁部１３の外周端との間には、該底壁部１３を支持して補強する側面略三角板状の補強リブ１４を所定間隔毎に複数それぞれ一体突出形成してある。さらに、周壁部１２の外周面１２ｂの栓本体１１の裏面１１ｂと係止部１２ｃとの間にはシール部１２ｄを一体突出形成してある。
【００１６】
また、底壁部１３の表面１３ａの略中央には、ボデーパネル１７の開口部１８への装着時に押圧される略円柱状の操作部１５を一体突出形成してある。この操作部１５の上面が押し面１５ａとなっていて、該押し面１５ａを作業者が指１９で押圧することにより、閉塞栓１０がボデーパネル１７の開口部１８に装着されて該開口部１８が閉塞されるようになっている。尚、操作部１５の押し面１５ａは栓本体１１の表面１１ａより下方に位置している。
【００１７】
さらに、各補強リブ１４と略円柱状の操作部１５とは連結リブ１６でそれぞれ連結されている。即ち、この各連結リブ１６は底壁部１３の表面１３ａ上より板状に一体突出形成されて各補強リブ１４の傾斜面１４ａの下端と略円柱状の操作部１５の外周面１５ｂの下端とを一体的にそれぞれ連結している。
【００１８】
以上実施形態のゴム製の閉塞栓１０によれば、図２に示す状態から該閉塞栓１０をボデーパネル１７の開口部１８へ装着する際に、図３に示すように、閉塞栓１０の操作部１５の押し面１５ａをボデーパネル１７の裏面１７ｂ側に指１９で押圧すると、底壁部１３が従来のように湾曲状に弾性変形することなく、ボデーパネル１７の開口部１８側に押し付けられる。これにより、ボデーパネル１７の開口部１８の手前側にある周壁部１２の環状の係止部１２ｃの外径が縮径され、該係止部１２ｃが開口部１８の開口縁を乗り越えて挿通されてボデーパネル１７の裏面１７ｂ側に係止される。
【００１９】
このゴム製の閉塞栓１０では、周壁部１２の内周面１２ａに一体突出形成された各補強リブ１４と底壁部１３の表面１３ａ上の操作部１５との間が離れることなく各連結リブ１６でそれぞれ一体的に連結されているため、閉塞栓１０をボデーパネル１７の開口部１８に装着する時に、各補強リブ１４と操作部１５との間の底壁部１３が従来のように湾曲状に弾性変形して延びることがなく、操作部１５の押し面１５ａを指１９で押す押圧力Ｆが直接作用して逃げることがない。
【００２０】
詳述すると、各連結リブ１６を底壁部１３の表面１３ａ上より一体突出形成させて各補強リブ１４と略円柱状の操作部１５とを一体的にそれぞれ連結したことにより、図３に示すように、閉塞栓１０をボデーパネル１７の開口部１８に装着する時に、略円柱状の操作部１５による押圧力Ｆが各連結リブ１６を介して各補強リブ１４（即ち周壁部１２及び栓本体１１側）に直接かつ効率良く作用する。これにより、略円柱状の操作部１５と各補強リブ１４間の底壁部１３が従来のように大きく弾性変形して湾曲状に延びることがなく、該操作部１５の押圧力Ｆにより閉塞栓１０をボデーパネル１７の開口部１８に簡単かつ短時間で装着することができ、閉塞栓１０のボデーパネル１７の開口部１８への装着作業性をより一段と向上させることができる。
【００２１】
尚、前記実施形態によれば、ゴム製の閉塞栓について説明したが、熱可塑性エラストマー樹脂等の弾性材料により閉塞栓を形成しても良い。
【００２２】
【発明の効果】
以上説明したように、請求項１の発明によれば、底壁部の表面の略中央に形成されて被閉塞部材の開口部への装着時に押圧される操作部の外周面の下端と、周壁部の内周面の栓本体の内周端と底壁部の外周端との間に形成されて該底壁部を補強する複数の補強リブの下端と、を連結リブで一体的にそれぞれ連結したことにより、閉塞栓を被閉塞部材の開口部に装着する時に、操作部による押圧力を各連結リブを介して各補強リブに直接作用させることができ、閉塞栓の被閉塞部材の開口部への装着作業性を向上させることができる。
【００２３】
請求項２の発明によれば、操作部を略円柱状に一体突出形成すると共に、各連結リブで略円柱状の操作部の外周面の下端と各補強リブの傾斜面の下端とを一体的にそれぞれ連結したことにより、閉塞栓を被閉塞部材の開口部に装着する時に、略円柱状の操作部による押圧力を各連結リブを介して各補強リブに直接かつ効率良く作用させることができ、略円柱状の操作部と各補強リブ間の底壁部が延びることがなくなって閉塞栓の被閉塞部材の開口部への装着作業性をより一段と向上させることができる。また、請求項３の発明によれば、操作部が栓本体の表面より下方に位置しているため、被閉塞部材の開口部への閉塞栓の装着時にその縮径を妨げることがなく、被閉塞部材からの反力が少なく装着し易くなる。
