Description

【０００１】
【発明の属する技術分野】
この発明は、被取付部材に取付部材を取り付けるためのスクリューグロメットに関するものである。
【０００２】
【従来の技術】
図８は上記した従来のスクリューグロメットの要部を示す平断面図に相当する説明図である。
図８において、Ｐは被取付部材としての鋼板を示し、長方形の取付孔ｈが設けられている。
Ｇはスクリューグロメットを示し、鋼板Ｐに当接する図示を省略した鍔部と、この鍔部から垂下し、取付孔ｈに挿入される脚部２１と、この脚部２１の対向する周面に設けられた抜け止め機構４１とで構成されている。
【０００３】
そして、鍔部、脚部２１および抜け止め機構４１はプラスチックで一体成形され、タッピングスクリューＳがねじ込まれる穴３１が、鍔部から脚部２１へ開設されている。
上記した抜け止め機構４１は、脚部２１の軸方向へ向く３つの抜け止め片４２で構成されている。
なお、各抜け止め片４２は、脚部２１を鋼板Ｐの取付孔ｈへ挿入すると、取付孔ｈの縁に衝合する高さとされている。
【０００４】
次に、スクリューグロメットＧの取付について説明する。
まず、スクリューグロメットＧの脚部２１を鋼板Ｐの取付孔ｈへ挿入する。
このように脚部２１を取付孔ｈへ挿入すると、抜け止め機構４１の各抜け止め片４２は取付孔ｈの縁に衝合する高さとされているので、各抜け止め片４２が取付孔ｈの縁に衝合した後は鍔部を押圧し、図８に点線で示すように、各抜け止め片４２を取付孔ｈへ挿入させる。
【０００５】
そして、穴３１にタッピングスクリューＳをねじ込んで脚部２１を拡径させると、図８に実線で示すように、鍔部とで鋼板Ｐを挟持するように各抜け止め片４２が取付孔ｈの外側へ移動するので、鍔部と各抜け止め機構４１とで鋼板Ｐを挟持する状態となり、鋼板ＰにスクリューグロメットＧを抜けないように取り付けることができる。
【０００６】
【発明が解決しようとする課題】
従来のスクリューグロメットＧは、抜け止め機構４１を構成する全ての抜け止め片４２が取付孔ｈの縁に衝合するので、鋼板Ｐに取り付けるため、脚部２１を取付孔ｈへ挿入する挿入力が大きくなり、取付性が悪いという不都合があった。
【０００７】
この発明は、上記したような不都合を解消するためになされたもので、抜去力を従来と同等またはより大きくしつつ挿入力を小さくして取付性を向上させることのできるスクリューグロメットを提供するものである。
【０００８】
【課題を解決するための手段】
この発明のスクリューグロメットは、鍔部と、この鍔部から垂下した脚部と、鍔部から脚部へ開設されたタッピングスクリューがねじ込まれる穴と、脚部の軸方向へ向く少なくとも１つずつの第１抜け止め片、第２抜け止め片を１組として脚部の周方向へ近接させて配設された抜け止め機構とで構成されている。
なお、第１抜け止め片は肉薄で、脚部を被取付部材の取付孔へ挿入すると、取付孔の縁に僅かに衝合する高さとされ、第２抜け止め片は第１抜け止め片よりも肉厚で、取付孔へ挿入すると、取付孔の縁との間に隙間を形成する高さとされ、穴にタッピングスクリューをねじ込むことにより、脚部が拡径して鍔部とで被取付部材を挟持するように第１および第２抜け止め片が取付孔の外側へ移動する。そして、抜け止め機構を脚部の周方向へ２つ以上設けたり、脚部を四角柱状にして対向する周面に抜け止め機構を設けたりしてもよい。
【０００９】
【発明の実施の形態】
以下、この発明の実施形態を図に基づいて説明する。
図１はこの発明の一実施形態であるスクリューグロメットの平面図、図２はこの発明の一実施形態であるスクリューグロメットの正面図、図３はこの発明の一実施形態であるスクリューグロメットの右側面図、図４はこの発明の一実施形態であるスクリューグロメットの底面図、図５は図１のＸ−Ｘ線による断面図、図６（ａ），（ｂ）および図７は図１〜図５に示したスクリューグロメットを鋼板に取り付ける説明図であり、図８と同一部分に同一符号を付して説明を省略する。
なお、図６（ｂ）は図７のＹ−Ｙ線による断面図に相当し、図７は図６（ｂ）のＺ−Ｚ線による断面図に相当する。
【００１０】
これらの図において、スクリューグロメットＧは、鋼板Ｐに当接する鍔部１１と、この鍔部１１から垂下し、取付孔ｈに挿入される脚部２１と、この脚部２１の対向する周面に設けられた抜け止め機構４１とで構成されている。
そして、鍔部１１、脚部２１および抜け止め機構４１はプラスチックで一体成形され、タッピングスクリューＳがねじ込まれる穴３１が、鍔部１１から脚部２１へ開設されている。
【００１１】
上記した鍔部１１には、例えばフックなどを取り付けるための係止部１２が設けられている。
また、抜け止め機構４１は、脚部２１の軸方向へ向く２つの第１抜け止め片４３、および１つの第２抜け止め片４４で構成されている。
なお、第１抜け止め片４３は、肉厚が例えば０．８ｍｍで、脚部２１を鋼板Ｐの取付孔ｈへ挿入すると、取付孔ｈの縁に０．２ｍｍ〜０．３ｍｍの範囲で衝合する高とされている。
【００１２】
また、第２抜け止め片４４は、肉厚が例えば１．６ｍｍで、脚部２１を取付孔ｈへ挿入すると、取付孔ｈの縁との間に０．１ｍｍの隙間を形成する高さとされている。
そして、各抜け止め片４３，４４は、取付孔ｈへ挿入し易くするため、図２および図７に示すように、下側から上昇するに連れて脚部２１の外側へ順次広がり、上端と鍔部１１との間が鋼板Ｐの厚さとされている。
Ｄはパッドを示し、鋼板Ｐと鍔部２１との間に配設される。
【００１３】
次に、スクリューグロメットＧの取付について説明する。
まず、スクリューグロメットＧの脚部２１を鋼板Ｐの取付孔ｈへ挿入する。
このように脚部２１を取付孔ｈへ挿入すると、抜け止め機構４１の第１抜け止め片４３は取付孔ｈの縁に衝合する高さとされているので、第１抜け止め片４３が取付孔ｈの縁に衝合した後は鍔部１１を押圧し、図６（ａ）に示すように、各抜け止め片４３，４４を取付孔ｈへ挿入させる。
【００１４】
そして、穴３１にタッピングスクリューＳをねじ込んで脚部２１を拡径させると、図６（ｂ）および図７に示すように、鍔部１１とで鋼板Ｐを挟持するように各抜け止め片４３，４４が取付孔ｈの外側へ移動するので、鍔部１１と各抜け止め機構４１とで鋼板Ｐを挟持する状態となり、鋼板ＰにスクリューグロメットＧを抜けないように取り付けることができる。
【００１５】
上述したように、この発明の一実施形態によれば、第１抜け止め片４３の肉厚を薄くし、第１抜け止め片４３の高さを取付孔ｈの縁に僅かに衝合する高さとするとともに、第２抜け止め片４４の高さを取付孔ｈの縁との間に隙間を形成する高さとしたので、鋼板Ｐに取り付ける際の挿入力を小さくすることができ、取付性を向上させることができる。
そして、第２抜け止め片４４の肉厚を厚くしたので、第１抜け止め片４３の抜去力に第２抜け止め片４４の抜去力を加えた総合的な抜去力を、従来と同等またはより大きくすることができ、鋼板Ｐに強固に取り付けることができる。
【００１６】
上記した実施形態おいては、脚部２１の対向する周面にそれぞれ抜け止め機構４１を設けたが、一方のみの抜け止め機構４１であっても同様な効果を得ることができ、残りの周面にも抜け止め機構４１を設けてもよい。
そして、抜け止め機構４１を、２つの第１抜け止め片４３と、１つの第２抜け止め片４４とで構成したが、少なくとも１つの第１抜け止め片４３と、少なくとも１つの第２抜け止め片４４とで構成し、第２抜け止め片４４の幅を所望の値に設定することにより、同様な効果を得ることができる。
【００１７】
さらに、取付孔ｈを長方形とするとともに、脚部２１を角柱状にし、スクリューグロメットＧを鋼板Ｐに方向性を持たせて取り付けることができるようにしたが、方向性を持たせて取り付ける必要性がない場合、例えば鍔部１１に係止部１２を設けず、穴３１へタッピングスクリューＳで取付部材を、スクリューグロメットＧを介して鋼板Ｐに取り付ける場合、取付孔を円形とし、脚部も円柱状にしてもよい。
【００１８】
このように脚部を円形状にした場合、この発明に係る抜け止め機構を脚部の周面に１つ以上設ければ、同様な効果を得ることができる。
なお、円形状の脚部の周面に、２つの抜け止め機構を設ける場合、２つの抜け止め機構を１８０度の位置関係に設けたり、他の位置関係に設けてもよく、また、３つの抜け止め機構を設ける場合、３つの抜け止め機構を１２０度間隔に設けたり、他の位置関係に設けてもよく、さらに、４つの抜け止め機構を９０度間隔に設けたり、他の位置関係に設けてもよい。
【００１９】
【発明の効果】
以上のように、この発明によれば、第１抜け止め片の肉厚を薄くし、第１抜け止め片の高さを被取付部材の取付孔の縁に僅かに衝合する高さとするとともに、第２抜け止め片の高さを取付孔の縁との間に隙間を形成する高さとしたので、被取付部材に取り付ける際の挿入力を小さくすることができ、取付性を向上させることができる。
【００２０】
そして、第２抜け止め片の肉厚を厚くしたので、第１抜け止め片の抜去力に第２抜け止め片の抜去力を加えた総合的な抜去力を、従来と同等またはより大きくすることができ、被取付部材に強固に取り付けることができる。
さらに、抜け止め機構を脚部の周面に２つ以上設けると、より一層抜去力を大きくすることができ、被取付部材に強固に取り付けることができる。
