Description

【０００１】
【発明の属する技術分野】
本発明は、車室内に装着されるアシストグリップの取付構造に関する。
【０００２】
【従来の技術】
従来より、この種のアシストグリップの取付構造として、例えば、米国特許第４，９８１，３２２号公報に開示されるように、グリップ本体に取付座を設け、この取付座を車体パネル（固定体）に固定するようにした構造が知られている。このものでは、取付座に車体パネルの取付孔へ挿入される一対の係止片を形成し、この取付座の固定に際しては、取付孔に挿入した係止片の間にロックピンを差し込むことで該係止片の間隔を拡げて、該係止片の先端側に設けた係止爪部を上記車体パネルの取付孔周縁部に係止させるようにしており、この構造では、アシストグリップの車体への組み付け作業をロックピンの挿入のみにより容易にかつ迅速に行うことができる。
【０００３】
また、上記従来例では、ロックピンを取付座の係止片間に途中まで挿入した仮保持位置で保持してからアシストグリップを車体組立ラインに搬入することで、該組立ラインにおけるアシストグリップの組み付け工数をより一層削減するようにしている。
【０００４】
【発明が解決しようとする課題】
ところで、上記従来例のようにロックピンを仮保持位置で保持した状態で車体組立ラインに搬入するようにすると、車体への組み付け前にロックピンが完全に押し込まれたり、あるいは取付座から抜け落ちたりすることがある。すなわち、ロックピンの仮保持位置での係止片のロックピンに対する保持力が十分でないと、ロックピンが完全に押し込まれて、係止爪部が取付孔の開口寸法を越えて拡がった状態となるため、そのままではアシストグリップを取り付けることができず、ロックピンを引き抜く手間がかかる。また、ロックピンが取付座から抜け落ちて紛失する虞れもある。
【０００５】
一方、ロックピンを仮保持位置において係止片により十分に強い力で挟み込んで保持するようにすると、組み付け時にロックピンを押し込む際、係止片との間の摺動抵抗に対抗する大きな力が必要となるから、組み付け作業性が悪化するという問題がある。
【０００６】
本発明は斯かる諸点に鑑みてなされたものであり、その目的とするところは、アシストグリップの取付座に、固定体の取付孔に挿入される一対の係止片を設け、該係止片間にロックピンを挿入して取付座を固定体に取り付けるようにする場合に、アシストグリップの固定体への組み付け前に仮保持位置にあるロックピンが押し込まれたり抜け落ちたりすることを防止しながら、組み付け時の作業性を良好なものとすることにある。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、本発明の解決手段では、一方の係止片にロックピンを仮保持位置で保持するための仮保持用保持部を形成し、他方の係止片に仮保持位置にあるロックピンの他方の側面に当接する当接部を形成し、ロックピンが仮保持位置よりも深く挿入された状態で係止片と非当接となるようにした。
【０００８】
具体的には、請求項１の発明では、アシストグリップのグリップ本体を固定体に取り付ける取付座と、上記固定体の取付孔へ挿入されるように上記取付座の裏面から一体に互いに離間して延び、それぞれ、離反する方向に突出する係止爪部が設けられた一対の係止片とを備え、該一対の係止片の間にそれらの間隔を拡げるように板状のロックピンを挿入して上記係止爪部を上記取付孔の周縁部に係止させるようにしたアシストグリップの取付構造を前提とする。そして、上記一対の係止片のうちの一方の係止片には、ロックピンの一方の側面に形成された係合部と係合して該ロックピンを取付座の本固定位置まで挿入する手前の仮保持位置で保持する仮保持用保持部を形成し、他方の係止片には、上記仮保持位置にあるロックピンの他方の側面に当接するように突出する当接部を上記ロックピンの係合部近傍に対向して形成し、上記ロックピンの他方の側面には、該ロックピンが上記仮保持位置よりも深く挿入された状態で上記当接部と非当接の段差面を形成する構成とする。
【０００９】
この構成によれば、グリップ本体部の取付座から延びる一対の係止片の間にロックピンを挿入すると、まず、一方の係止片の仮保持用保持部とロックピンの一方の側面に形成された係合部とが係合し、このことで一方の係止片によってロックピンが取付座の本固定位置まで挿入される手前の仮保持位置で保持される。このとき、ロックピンの他方の側面は、該ロックピンの係合部近傍に対向して他方の係止片に形成された当接部によって当接支持されるので、上記係合部及び仮保持用保持部をしっかりと係合させることができ、もって、ロックピンを十分に強い力で保持できる。従って、例えばロックピンを取付座に仮保持位置で保持させてから、アシストグリップを固定体への組み付け場所へ搬入するようにしても、組み付け前までにロックピンが押し込まれたり、また、取付座から抜け落ちたりすることはない。
【００１０】
そして、アシストグリップの固定体への組み付け時には、上記取付座の一対の係止片を固定体の取付孔へ挿入した後、仮保持位置にあるロックピンを押し込んで挿入する。この際、ロックピンが仮保持位置よりも深く挿入されると、該ロックピンの他方の側面が他方の係止片の当接部と非当接となるので、それ以降のロックピンの挿入に対して、当接部との摺動抵抗が作用することはなく、容易に作業が行える。
【００１１】
【発明の実施の形態】
図１〜図７は、本発明の実施形態に係る回動型の格納式アシストグリップＧを示し、このアシストグリップＧは、主としてグリップ本体１と一対の取付座６，７とからなるものである。上記グリップ本体１は例えばＰＰ（ポリプロピレン樹脂）等からなる長尺状のもので、図１に示すように、本体部の長さ方向両端部が湾曲されて略コ字状をなし、その長さ方向の両端部である左右両端部がそれぞれ脚部１ａ，１ｂとされていて、この左右の両脚部１ａ，１ｂにて例えば固定体としての車体パネルＰに固定された取付座６，７に対し回動可能に軸支されている。そして、グリップ本体１は、その長手方向が車体の前後方向と略一致するように上記車体パネルＰに取り付けられている。
【００１２】
上記車体パネルＰは、図例では車両における車室内の側壁をなすものであり、上記のような各脚部１ａ，１ｂでの軸支構造によりグリップ本体１が使用位置及び格納位置の間で回動して、図２に示すように格納位置にあるときにはグリップ本体１は車体パネルＰに沿った状態となる一方、図１、３に示すように使用位置にあるときには、グリップ本体１はその中間部が車室内方に突出して水平面からやや斜め下方に向いた状態となる。
【００１３】
そして、上記図２に示すようにグリップ本体１が格納位置にあるときに、その各脚部１ａ，１ｂの外面（車体パネルＰに対向する面）には、該外面側が開口するように、それぞれ、グリップ本体１の脚部１ａ，１ｂの先端面、即ち同図の下端面から図の上側に向かって略矩形状に切り欠いてなる切欠部が形成されていて、この各切欠部がそれぞれグリップ本体１の格納状態で取付座６，７の一部分を収容する収容部２，２となる。また、詳しくは後述するが、グリップ本体１の一方の脚部１ａ（図１において左側の脚部）と一方の取付座６との間には、グリップ本体１の回動に粘性抵抗を付与する粘性ダンパ１６が一体的に設けられ、一方、他方の脚部１ｂ（図１において右側の脚部）と他方の取付座７との間には、グリップ本体１を格納位置に向かうように回動付勢する捩りコイルばね１７が配設されている。
【００１４】
すなわち、図４及び図５に示すグリップ本体１の脚部１ａにおいて、収容部２の左右方向（グリップ本体１の長さ方向）に対向する２つの側壁のうち、グリップ本体１の左右中央に近い側に位置する内側側壁（図１で右側のもの）は軸受部３として形成され、この軸受部３の内側（収容部２側）面には有底の円形穴からなる軸受穴４が形成されている。一方、グリップ本体１の左右中央から遠い側に位置する外側側壁３ａ（図１で左側のもの）には、該側壁３ａをその厚み方向（図の左右方向）に貫通するようにスペーサ装着孔５が形成されている。このスペーサ装着孔５は、図１に示すように、グリップ本体１の長手方向からのグリップ本体１の脚部１ａの外観視（図１において左側からグリップ本体１の上記側壁３ａを見た状態）において略半円形状とされていて、その半円形状の中心位置が上記軸受穴４の中心線（軸線Ｘ）に一致するように形成されている。
【００１５】
そして、上記一方の脚部１ａの収容部２には、上記取付座６の一部が配置収容されている。この取付座６は、例えばＰＯＭ（ポリアセタール樹脂）等からなる樹脂材料によって形成され、車室側から車体パネルＰ側へ貫通する筒状の固定部８を有している。また、詳細は後述するが、上記取付座６の車室側には固定部８の一側壁（図４における下側壁）と一体に支持部１１が形成されている。
【００１６】
上記固定部８は、図５に示すように平面視で取付座６の支持部１１に近い側の幅が広く、その反対側へ向かって徐々に狭くなるような略Ｕ字状とされており、この固定部８の車体パネルＰ側には、該車体パネルＰに沿うように延びるフランジ５０が一体に形成されていて、該フランジ５０の車体パネルＰ側の面にはそれぞれグリップ本体１の長さ方向に延びるとともに、取付座７の取付時に車体パネルＰに当接する一対のパネル押さえ部５１，５１が形成されている。
【００１７】
上記固定部８の内方には、該固定部８の内周面における車室側に一体に形成されてそこから車体パネルＰの取付孔５５に挿入されるように延びる一対の係止片５３，５４が設けられている。この一対の係止片５３，５４は、グリップ本体１の長さ方向に沿って車体パネルＰに対して略垂直にかつ互いに所定距離離間して延びている。尚、この一対の係止片５３，５４のうち、支持部１１側に位置する係止片５３を第１係止片とし、他方の係止片５４を第２係止片とする。
【００１８】
上記第１及び第２係止片５３，５４はともに矩形板状とされていて、それぞれの先端側には上記車体パネルＰの取付孔５５周縁部に係止する係止爪部５６，５７が形成されている。第１係止片５３側の係止爪部５６は、該第１係止片５３の先端からその基端側（車室側）へ向かって係止片５３の側面から遠ざかるように傾斜する先端側傾斜面と、この先端側傾斜面に連なって係止片５３の基端側へ向かって該係止片５３の側面に近接するように傾斜する基端側傾斜面とを有する。尚、第２係止片５４の係止爪部５７も同様に、先端側傾斜面と基端側傾斜面とを有する。
【００１９】
第１係止片５３の第２係止片５４と対向する側面５３ａには、図１９（ａ）に示すように、上記係止爪部５６に対応する位置に断面三角形状に突出した一対の固定位置係合部５８，５８が係止片５３の幅方向（グリップ本体１の長手方向）に離間して形成されており、詳細は後述するが、この固定位置係合部５８，５８によって、完全に挿入された状態のロックピン６０、即ち、取付座７を車体パネルＰに固定する位置（本固定位置）まで挿入されたロックピン６０が保持されるようになっている。また、上記側面５３ａにおける第１係止片５３の基端側には、上記固定位置係合部５８，５８と同様な断面形状を有する仮保持位置係合部６１（仮保持用保持部）が第１係止片５３の幅方向中央部分にその幅方向に長く形成されており、この仮保持位置係合部６１によって、上記ロックピン６０が完全に挿入される手前の仮保持位置で保持される。
【００２０】
また、第２係止片５４の第１係止片５３と対向する側面５４ａには、図１９（ｂ）に示すように、上記第１係止片５３の固定位置係合部５８，５８に対応して同形状の固定位置係合部６２，６２が形成されており、固定位置係合部５８，５８と同様に、固定位置係合部６２，６２によっても本固定位置まで挿入されたロックピン６０が保持される。一方、この側面５４ａの基端側には、上記第１係止片５３の仮保持位置係合部６１と対向して矩形断面の一対の突出部６３，６３（当接部）が第２係止片５４の幅方向（グリップ本体１の長手方向）に離間して形成されている。
【００２１】
上記ロックピン６０は、図１４〜１７に示すように、固定部８の車室側開口を塞ぐ蓋部６４と該蓋部６４の裏面側から突出して第１及び第２係止片５３，５４間に挿入されるように延びる矩形板状のピン部６５とからなる。上記蓋部６４は、固定部８の車室側端面の形状に対応する形状に形成される一方、ピン部６５は、係止片５３，５４と略平行に該係止片５３，５４の先端側へ向かって長く延びるように形成されている。図１５に示すように、上記ピン部６５の幅方向（グリップ本体１の長手方向）両端部には、それぞれ第１係止片５３側の側面６５ａ（一方の側面）から突出する矩形断面のリブ６６，６６が設けられている。該リブ６６，６６の突出方向の先端面は、ピン部側面６５ａと略平行な平坦面とされている。このリブ６６，６６はピン部６５の基端側において上記蓋部６４に連繋される一方、ピン部６５の先端側においてピン部側面６５ａから膨出した連繋部６７によって互いに連繋されている。該連繋部６７のピン部６５先端部分には断面Ｖ字状の溝部６７ａ（係合部）がピン部６５の幅方向全体に亘って形成されている。
【００２２】
一方、図１６の示すように、ピン部６５の第２係止片５４側の側面６５ｂ（他方の側面）にも、上記第１係止片５３側の側面６５ａのリブ６６，６６と同様なリブ６８，６８が形成されており、このリブ６８，６８のピン部６５先端側には、上記溝部６７ａと同様な断面を有する切欠部７０が形成されていて、さらに該切欠部７０のピン部６５先端側には、その先端側ほどピン部側面６５ｂに近接する傾斜面が連なっている。そして、ピン部６５における第１係止片５３側のリブ６６の突出方向先端から第２係止片５４側のリブ６８の突出方向先端までの寸法は、上記２つの係止片５３，５４の離間距離と略同じとされている。また、本発明の特徴として、図１７にも示すように、ピン部６５の側面６５ｂにおける基端と先端との略中央部には段差部６９が形成されていて、これによって、ピン部６５の第２係止片５４側の側面６５ｂは、その基端からピン部６５の長手方向の略中央部までの部分がそこから先端までの部分よりもピン部６５の他方の側面６５ａ側に位置するような段差面６５ｃとされている。また、ピン部６５の幅方向の両端面には、それぞれピン部６５の基端側から先端側に亘って延びる突条部７１，７１が形成されており、ロックピン６０の挿入の際、この突条部７１，７１が上記固定部８の内周面における第１及び第２係止片５３，５４の間に設けられたガイド部７２，７２（図１１及び図１２参照）に摺接して案内されるようになっている。
【００２３】
図５及び図６に示すように、上記取付座６の支持部１１は全体として左右方向（グリップ本体１の長さ方向）に長い有底円筒形状をなし、その左右方向の両側面のうち、グリップ本体１の軸受部３に対向する一方の側面には該側面から突出する支軸１２が一体に形成されていて、この支軸１２の先端部が上記軸受部３の軸受穴４に回動可能に嵌挿されている。このことで、グリップ本体１は脚部１ａの軸受部３にて取付座６の支軸１２に回動可能に支持されている。
【００２４】
一方、上記取付座６の支持部１１の他方の側面には、上記支軸１２側に向かって内径が次第に小さくなるテーパ穴からなる有底の凹部１３が上記支軸１２と同心状に形成されるとともに、この凹部１３の底部１３ｂからその開口側に向かって、上記支軸１２と同心状に延びる先細りテーパ形状の嵌入軸１４が設けられている。換言すれば、上記凹部１３は上記収容部２の上記外側側壁３ａ側に開放されている。また、脚部１ａのスペーサ装着孔５には略有底筒形状のスペーサ１８が回動不能に取付固定されていて、このスペーサ１８の先端部が上記支持部１１の凹部１３内に回動可能に挿入されている。すなわち、スペーサ１８の先端部は、先細りテーパ形状の挿入部１９と、この挿入部１９の基端側に段差状に連続する相対的に大径の大径部２０とからなり、挿入部１９は支持部１１の凹部１３内に挿入されて、その挿入状態で挿入部１９外周面と凹部１３内周面との間に略一定の隙間が形成されるようになっている。
【００２５】
また、上記大径部２０は支持部１１の凹部１３の開口部１３ａに嵌合されており、この大径部２０により凹部１３の開口部１３ａを相対回転可能とするとともに、上記スペーサ１８の大径部２０と凹部１３の開口部１３ａとの間にはＯリング２１が介在され、後述する上記挿入部１９外周面と凹部１３内周面との間の隙間、及び嵌入部２９内周面と支持部１１の嵌入軸１４外周面との間の隙間に充填された粘性剤Ｌの流出を防止している。
【００２６】
上記スペーサ１８の基端部２２は、その外径形状が上述の上記グリップ本体１の脚部１ａにおけるスペーサ装着孔５と略同じ形状とされ、この基端部２２がスペーサ装着孔５に内嵌合されて、脚部１ａの上記外側側壁３ａに対するスペーサ１８の軸線回りの回動を阻止するように、すなわちグリップ本体１と一体となって回動するようになっている。
【００２７】
また、スペーサ１８の基端部２２と挿入部１９との間を繋ぐスペーサ１８の中間部分は、各々軸線Ｘ方向に延びる４つの中間連繋部２３，２４，２５，２６（２３，２４は図５に、また２３，２５，２６は図６にそれぞれ示す）からなり、該各中間連繋部２３，２４，…の外周部には、スペーサ１８の直径方向に対向した位置に互いに対をなす抜止め用爪２７が突設されている。そして、スペーサ１８をスペーサ装着孔５に挿通したときに、上記抜止め用爪２７，２７，…が脚部１ａの収容部２の上記外側側壁３ａ側面に係止されて、スペーサ１８のスペーサ装着孔５からの抜けを防止するようになっている。
【００２８】
さらに、上記スペーサ１８の挿入部１９の内部には、その先端面から基端側に向かって基端側が小径のテーパ状の有底穴からなる嵌入部２９が形成されている。この嵌入部２９の内部には、スペーサ１８が回転可能となるように上記支持部１１の嵌入軸１４が嵌入されるようになっており、この嵌入状態で、嵌入軸１４の外周面と嵌入部２９の内周面との間に隙間が形成されるとともに、該嵌入軸１４の先端面と嵌入部２９の底面２９ａとの間にも隙間が形成される。そして、それらの隙間同士が互いに連通するとともに、スペーサ１８の挿入部１９の先端面と凹部１３の底面１３ｂとの間の隙間を介して該挿入部１９の外周面と凹部１３の内周面との間の隙間にも連通していて、このように連続する４つの隙間に例えばシリコン等の高粘度（１０００００ｃｐｓ以上が望ましい）の粘性剤Ｌが充填されている。これにより、グリップ本体１の回動に粘性抵抗を付与する粘性ダンパ１６が構成される。
【００２９】
ここで、上記図５、６に示すようにスペーサ１８先端側の挿入部１９が支持部１１の凹部１３内に挿入されて、その挿入部１９内の嵌入部２９に上記支持部１１の嵌入軸１４が嵌入された状態で、スペーサ１８の挿入部１９の先端面と支持部１１の凹部１３の底面１３ｂとの間の隙間αは、該スペーサ１８の挿入部１９における嵌入部２９の底面２９ａと嵌入軸１４の先端面との間の隙間βよりも大きくなっている。言い換えると、上記スペーサ１８の長さ、嵌入部２９の深さ、支持部１１の凹部１３の深さ、嵌入軸１４の長さ等の寸法、及びそれら各部の相互の位置関係は、上記隙間αが隙間βよりも大きくなるように設定されており、詳しくは後述するが、このことで、取付座６へのスペーサ１８の取り付けの際、それらの隙間に空気が残存するのを阻止することができる。
【００３０】
一方、他方の取付座７は、図２、３、７に示すように、グリップ本体１の脚部１ｂに対する支持構造のみが上記取付座６とは異なっていて、この支持部７は別体の支持軸３１により軸支されている。以下の説明では、上記取付座７において取付座６と同様の構成の部分については同じ符号を付して、その詳細な説明は省略する。そして、上記脚部１ｂでは、図７に示すように収容部２の左右両側壁（グリップ本体１の長さ方向に対向する２つの側壁）がいずれも軸受部３，３とされていて、図で左側の軸受部３の内面には有底状の軸受穴４ａが、また右側の軸受部３には貫通状の軸受孔３０がそれぞれ同心状に形成されている。
【００３１】
上記取付座７には、取付座６の支持部１１と同様にして固定部８と一体に支持部３２が形成されている。この支持部３２は、全体として左右方向（グリップ本体１の長さ方向）に長い略円筒形状のもので、その左右両側の壁部にはそれぞれ軸挿通孔３３，３４（図７にのみ示す）が同心状に貫通形成されている。そして、それら両軸挿通孔３３，３４に支持軸３１が貫通支持され、この支持軸３１の両端部がそれぞれ支持部３２の左右両側から外方に突出して、上記収容部２を形成する軸受部３，３の軸受穴４ａ及び軸受孔３０に嵌挿されている。この構成により、取付座７の支持部３２に対してグリップ本体１が支持軸３１によりその中心線（軸線Ｘ）の周りに回動可能に支持されている。
【００３２】
また、上記支持軸３１の長さ方向中間部の周りには捩りコイルばね１７が配置されている。すなわち、上記取付座７の支持部３２の内部にはグリップ本体１の長さ方向に長い断面略円形のコイルばね収納空間３２ａが形成されていて、この収納空間３２ａに捩りコイルばね１７が収納されている。換言すれば、上記取付座７の支持部３２は、捩りコイルばね１７を収納するコイルばね体収納部である。また、上記支持部３２内の収納空間３２ａの長さ方向の寸法は捩りコイルばね１７の長さよりも大きく、一方、収納空間３２ａの径方向の寸法は捩りコイルばね１７の直径よりも若干、大きく形成されており、このことで、捩りコイルばね１７は、その中心線が軸線Ｘと略一致する状態で収納空間３２ａ内をその長さ方向に移動可能となっている。
【００３３】
より詳しくは、上記支持部３２の周壁には、取付座７の車体パネルＰへの固定状態で下向きとなる所定の範囲に亘ってコイルばね挿入口３５が開設されるとともに、該コイルばね挿入口３５とは反対側の周壁を貫通して周方向に延びる第１スリット３６と、この第１スリット３６に連続して支持部３２の長さ方向（グリップ本体１の長さ方向）に延びる第２スリット３７とが形成されている。すなわち、図８に示すように捩りコイルばね１７の挿入方向から見ると、コイルばね挿入口３５は略矩形状とされ、その長さ方向及び幅方向についてコイルばね収納空間３２ａと略同じ大きさとされている。
【００３４】
また、上記第１スリット３６は、取付座７において固定部８との境界壁となる支持部３２の周壁を該支持部３２内の収納空間３２ａ（コイルばね収納部の内側）から固定部８の内部（コイルばね収納部の外側）まで貫通するとともに、支持部３２の一方の側壁（図８の左側壁）の内面（収容空間３２ａに臨む面）に沿って周方向（図８の上下方向）に延びている。また、第２スリット３７は、上記第１スリット３６の端部（図８の上端部）から支持部３２の長さ方向の中間部まで延びていて、該第１スリット３６と同様に支持部３２の周壁を貫通するとともに、収納空間３２ａから固定部８側に向かって開口幅（図８の上下方向の幅）が徐々に狭まるテーパ状とされている。そして、上記第１及び第２スリット３６，３７は、コイルばねの挿入方向から見ると、互いに連続して略Ｌ字状をなしている。
【００３５】
上記捩りコイルばね１７は、その長さ方向一端部（図７の左側の端部）の外周から線材が外方に延長されてなる延長部１７ａを有し、この延長部１７ａの先端側が折り曲げられて折曲部１７ｂが形成されている。この折曲部１７ｂの長さは第１スリット３６の長さ（図８の上下方向の長さ）よりも短くされていて、捩りコイルばね１７を支持部３２の長さ方向一側（図７、８の左側）に寄せた状態でコイルばね挿入口３５に挿入したときに、折曲部１７ｂが容易に第１スリット３６を通過するようになっている。また、上記捩りコイルばね１７は、その長さ方向の他端部（図７の右側の端部）を支持部３２の右側壁内面に接近した状態（収納位置）で収納空間３２ａに収納されており、この状態では該捩りコイルばね１７の延長部１７ａは第２スリット３７を貫通し、その先端側の折曲部１７ｂが固定部８の上記空間部８ａ内において第２スリット３７の周縁部に係止されている。
【００３６】
また、上記捩りコイルばね１７の他端部の外周からも線材が外方に延長されて延長部１７ｃとされており、この延長部１７ｃは、グリップ本体１の収容部２の内底壁（図２で下側の壁）に形成した溝部３８に係止されている。そして、捩りコイルばね１７の捩り力によって、グリップ本体１は常時は格納位置に位置付けられるように使用位置から格納位置に向かう方向（図２〜４で反時計回り方向）に回動付勢されている。
【００３７】
尚、上記図２〜４にそれぞれ示すように、上記グリップ本体１の各脚部１ａ，１ｂの先端側における収容部２の開口端部には、それぞれ当たり部３９が形成されており、一方、各取付座６，７の固定部８にはそれぞれ上記当たり部３９に当接可能なストッパ部４０が形成されている。そして、グリップ本体１が格納位置から使用位置に回動したときにその両方の脚部１ａ，１ｂの当たり部３９がそれぞれ取付座６のストッパ部４０に当接することで、グリップ本体１は、それ以上の回動が規制されて使用位置に停止される。
【００３８】
（アシストグリップの組立て）
次に、上述の如き構成のアシストグリップＧの組み立て手順について説明する。まず、取付座６については、その支軸１２をグリップ本体１の脚部１ａにおける軸受部３の軸受穴４に嵌挿して、支持部１１を収容部２内に収容し、次いで、グリップ本体１の脚部１ａにおけるスペーサ装着孔５にスペーサ１８をその先端側から挿通して、挿入部１９を支持部１１の凹部１３に挿入し、かつ嵌入部２９に支持部１１の嵌入軸１４を嵌入させる。これによりスペーサ１８の抜止め用爪２７が脚部１ａの収容部２の側面（外側側壁３ａの側面）に係止して、スペーサ１８の基端側を脚部１ａに固定する。そして、上記スペーサ１８の上記組み付けの前に予め上記スペーサ１８の嵌入部２９内に必要量の粘性剤Ｌを充填しておけば、上記スペーサ１８の組み付けと同時に、嵌入部２９に侵入する嵌入軸１４によって粘性剤Ｌが押し出されて、凹部１３内の隙間に拡がって充填される。
【００３９】
より詳しくは、図９に示すように、予めスペーサ１８の嵌入部２９内に必要な分量の粘性剤Ｌを入れておき、このスペーサ１８の挿入部１９をグリップ本体１の脚部１ａのスペーサ装着孔５を通過させて、取付座６の支持部１１に開口する凹部１３に軸線Ｘに沿うようにして挿入する。このとき、該凹部１３内をその底面１３ｂから開口部１３ａ側に向かって延びる嵌入軸１４がスペーサ１８の嵌入部２９に挿入される。
【００４０】
そして、図１０に示すように、スペーサ１８をその基端側までスペーサ装着孔５に嵌挿したとき、該スペーサ１８の挿入部１９は取付座６の凹部１３の奥側まで挿入され、これに伴い、該凹部１３の嵌入軸１４がスペーサ１８の嵌入部２９の奥側に挿入されて、その嵌入部２９内の粘性剤Ｌを押し出すようになる。このようにして粘性剤Ｌが嵌入部２９の内周面と嵌入軸１４の外周面との間の隙間から押し出されて、スペーサ１８の挿入部１９の先端面と凹部１３の底面１３ｂとの間の隙間に至り、さらにそこから該スペーサ１８の挿入部１９外周面と凹部１３内周面との間の隙間に押し出されて、この隙間を凹部１３の開口部１３ａに向かって移動する。
【００４１】
そうして、上記スペーサ１８の挿入部１９を支持部１１の凹部１３の最深部まで挿入したときには、該スペーサ１８の先端面と凹部１３の底面１３ｂとの間の間隔αが該スペーサ１８の嵌入部２９の底面２９ａと嵌入軸１４の先端面との間の間隔βよりも大きいことから、その嵌入軸１４の先端面が嵌入部２９の底面２９ａに当接もしくは当接直前で該嵌入部２９内の粘性剤Ｌを十分に押し出し、この押し出された粘性剤Ｌが凹部１３内の空気を殆ど全て排出するようになる。
【００４２】
かくして、上記スペーサ１８の挿入部１９外周面と支持部１１の凹部１３内周面との間の隙間から該スペーサ１８の先端面と凹部１３の底面１３ｂとの間の隙間を介して、該スペーサ１８の嵌入部２９内周面と嵌入軸１４外周面との間の隙間に連続し、さらにその嵌入部２９の底面２９ａと嵌入軸１４の先端面との間の隙間まで連続する隙間全体に亘って粘性剤Ｌが充填されるとともに、この隙間、即ち凹部１３内から空気が殆ど全て排出される。
【００４３】
一方、取付座７については、最初に該取付座７の支持部３２内に捩りコイルばね１７を収納し、それから取付座７をグリップ本体１の脚部１ｂに組み付ける。すなわち、まず、図１１(a)に示すように、捩りコイルばね１７をコイルばね挿入口３５に対して図の左側に寄せた状態で、即ち、捩りコイルばね１７の一端部を支持部３２の左側壁の内面に摺接させるようにして挿入する。こうすると、図１２(a)に示すように、捩りコイルばね１７の延長部１７ａがコイルばね挿入口３５から収納空間３２ａに入り、さらに第１スリット３６に挿通されて、同図に仮想線で示すように、捩りコイルばね１７の延長部１７ａの先端側が支持部３２の外側の空間部８ａに突出して折曲部１７ｂが固定部８の空間部８ａ内に位置するようになる。
【００４４】
続いて、図１１(b)に実線で示すように、捩りコイルばね１７をその長さ方向に収納位置までずらして、該捩りコイルばね１７の他端部が支持部３２の右側壁内面に当接するようにする。こうすると、延長部１７ａが第２スリット３７内を移動して、その先端の折曲部１７ｂが空間部８ａ内に臨む第２スリット３７の周縁部に係止されるようになり、これにより、捩りコイルばね１７はその中心線を軸線Ｘに略一致させた状態で収納空間３２ａに保持されることになる。つまり、捩りコイルばね１７をコイルばね挿入口３５から収納空間３２ａに挿入して、その長さ方向にずらすだけで、容易に収納空間３２ａ内に収納して保持することができる。尚、図11(b)では、捩りコイルばね１７を収容した取付座７を明らかにするために、支持部３２の一部を切り欠いて示している。
【００４５】
このようにして捩りコイルばね１７を収納した取付座７をグリップ本体１の脚部１ｂに取り付けるときには、取付座７の天地を図１２に示す状態から逆転させて、図１３に示すように、該取付座７の支持部３２をグリップ本体１の脚部１ｂの収容部２に上方から差し入れ、これとともに、捩りコイルばね１７の延長部１７ｃをグリップ本体１の脚部１ｂの溝部３８に挿入して係止させる。このとき、上記取付座７の支持部３２の左右両側壁の軸挿通孔３３，３４とグリップ本体１の脚部１ｂにおける収容部２の左右両軸受部３，３の軸受穴４ａ及び軸受孔３０とが互いに略同心状に位置付けられるとともに、それらと略同心状に捩りコイルばね１７も位置付けられることになるので、この状態で支持軸３１の先端側を上記脚部１ｂの貫通状軸受孔３０から軸受穴４ａに向かって挿入し、この支持軸３１により取付座７の軸挿通孔３３，３４と捩りコイルばね１７とを貫通させて、該支持軸３１の先端部を他方の軸受部３の有底状軸受穴４ａに嵌入させて固定する。尚、支持軸３１の基端側を軸受孔３０内でスナップリング等により抜け止めして、固定するようにしてもよい。
【００４６】
上述のようにしてグリップ本体１の脚部１ａ，１ｂにそれぞれ取付座６，７を組み付けた後は、この取付座６，７の各固定部８を車体パネルＰへ固定する。すなわち、まず、図１４に示すように、アシストグリップＧの取付座６，７の各固定部８へロックピン６０を仮保持位置で保持させる。このとき、ロックピン６０を第１及び第２係止片５３，５４間にこれら係止片５３，５４の基端側から挿入すると、ピン部６５の連繋部６７の先端傾斜面が第１係止片５３の仮保持位置係合部６１を乗り越えて該仮保持位置係合部６１が連繋部６７の溝部６７ａ内に位置するようになって両者が係合する一方、ピン部６５の第２係止片５４側の側面６５ｂのうち段差部６９より先端側の側面６５ｂに、該第２係止片５４の突出部６３，６３の先端面が当接してピン部６５を第１係止片５３側へ押しつけるようになり、このことで、ロックピン６０を十分に強い力で保持できる。
【００４７】
このように上記ロックピン６０が仮保持位置にあるときには、突出部６３，６３を第１係止片５３の仮保持位置係合部６１の近傍に対向させて設けていることにより、突出部６３，６３がピン部６５の側面６５ｂを仮保持位置係合部６１側へ確実に押さえつけることになり、もって、溝部６７ａと仮保持位置係合部６１とが外れることなくしっかりと係合するようになる。尚、この状態では、ロックピン６０の先端側が挿入されただけなので、両係止片５３，５４の先端側同士の離間距離は上記所定距離のままである。
【００４８】
次いで、上記のようにしてロックピン６０を仮保持位置で保持したアシストグリップＧを車体組立ラインに搬入して、取付座６，７のフランジ５０を車室内のトリム材５２に接合させるようにして取付位置に位置決めする。詳しくは、取付座６，７の係止片５３，５４を車体パネルＰの取付孔５５の車室側に位置付けて取付座６，７を挿入方向へ押しつけると、取付孔５５周縁部に当接した係止爪部５６，５７同士が接近するように係止片５３，５４が弾性変形して、係止爪部５６，５７が取付孔５５を貫通する。その後、係止片５３，５４はその弾性力により上記所定距離離れた状態に戻って取付座６，７の取付孔５５からの抜けが防止される一方、取付座６，７のそれぞれのパネル押さえ部５１，５１が車体パネルＰに当接する。
【００４９】
このようにしてアシストグリップＧ（取付座６，７）の位置決めを行った後、ロックピン６０の蓋部６４を押圧すると、図１８に示すように、ピン部６５の連繋部６７の溝部６７ａが仮保持位置係合部６１から外れてロックピン６０全体が挿入方向へ移動し、この直後、第２係止片５４の突出部６３，６３は、ピン部６５の段差面６５ｃに対応するようになる。すなわち、ロックピン６０が仮保持位置よりも深く挿入されると、ピン部６５の側面６５ｂが突出部６３，６３に当接しない状態（非当接状態）となり、このことで、ロックピン６０を深く挿入する際に、該ロックピン６０に対して突出部６３，６３との間の摺動抵抗が作用することはなく、もって、挿入時の力を小さくできる。
【００５０】
そして、さらにロックピン６０を挿入していくと、ピン部６５のリブ６６，６６，６８，６８の先端傾斜面が、それぞれ両係止片５３，５４の固定位置係合部５８，５８，６２，６２に接触して両係止片５３，５４の先端側の間隔を拡げるように該両係止片５３，５４を弾性変形させ、図２〜図４に示すように、ロックピン６０が本固定位置まで完全に挿入されて、固定位置係合部５８とピン部６５の溝部６７ａとが係合する一方、固定位置係合部６２とピン部６５の切欠部７０とが係合して、両係止片５３，５４がロックピン６０を本固定位置で保持するようになる。そして、この状態では、両係止片５３，５４の係止爪部５６，５７の基端側傾斜面が取付孔５５周縁部に車体パネルＰの裏側から接触し、このことで、取付座６，７は車体パネルＰに固定される。
【００５１】
したがって、上述の如く構成されたアシストグリップＧを車体に組み付ける場合には、まず、グリップ本体１の取付座６，７にロックピン６０を仮保持位置まで挿入して第１係止片５３に保持させた後、アシストグリップＧを車体組立ラインに搬入する。その際、ロックピン６０は第２係止片５４の突出部６３，６３によって第１係止片５３側へ押しつけられているので、第１係止片５３から外れることはなく、アシストグリップＧの取り付け前にロックピン６０が完全に押し込まれることや、取付座６，７から抜け落ちることを防止できる。
【００５２】
次いで、係止片５３，５４を車体パネルＰの取付孔５５に挿入してアシストグリップＧの位置決めを行った後、ロックピン６０を押圧して本固定位置まで深く挿入して、係止爪部５６，５７を取付孔５５の周縁部に係止させるとともに、ロックピン６０を本固定位置で係止片５３，５４に保持させる。このとき、ロックピン６０の第２係止片５４側に段差面６５ｃが形成されているので、仮保持位置にあるロックピン６０がその仮保持位置よりも深く挿入されると、ロックピン６０と係止片５４の突出部６３，６３とが非当接となるので、ロックピン６０の挿入を小さい力で行うことができ、アシストグリップＧの組み付け作業を容易にすることができる。
【００５３】
つまり、この実施形態によると、アシストグリップＧを位置決めした後に、仮保持位置にあるロックピン６０を押し込むだけで取付座６，７を車体パネルＰに強固に固定できるので、ボルト等を用いる場合と比べて容易にかつ迅速に組付作業を行うことができる。
【００５４】
また、この実施形態では、ロックピン６０からの係止片５３，５４間を拡げる力を大きく受ける固定位置係合部５８，６２を係止爪部５６，５７近傍に位置付けているので、係止爪部５６，５７を相対的に強く取付孔５５周縁部に押しつけることができ、よって、上記の如く組付作業を容易なものとしながらアシストグリップＧの取付強度を十分に確保できる。
【００５５】
尚、この発明に係るアシストグリップの取付構造は上記実施形態のように車両用のものに限定されるものでなく、また、グリップ本体１が上記使用位置にある状態で取付座６，７と一体成形された固定式のアシストグリップに適用してもよい。
【００５６】
【発明の効果】
以上説明したように、本願発明に係るアシストグリップの取付構造によると、グリップ本体の取付座に固定体の取付孔へ挿入される一対の係止片を設け、一方の係止片にロックピンの一方の側面の係合部と係合して該ロックピンを本固定位置まで挿入する手前の仮保持位置で保持する仮保持用保持部を形成し、他方の係止片に仮保持位置にあるロックピンの他方の側面に当接する当接部（突出部）を上記ロックピンの係合部近傍に対向して形成し、上記ロックピンの他方の側面に該ロックピンが仮保持位置よりも深く挿入された状態で当接部と非当接となる段差面を形成することで、一対の係止片の間に仮保持位置まで挿入したロックピンの他方の側面を当接部によって支持させてロックピンを仮保持用保持部によってしっかりと保持させることができ、例えばロックピンを取付座に仮保持位置で保持してから、アシストグリップを固定体への組み付け場所へ搬入するようにしても、仮保持位置にあるロックピンが押し込まれることや抜け落ちることを未然に防止できる。また、仮保持位置にあるロックピンを深く挿入すると、ロックピンと当接部とが非当接となり、組付作業を容易に行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for an assist grip mounted in a vehicle interior.
[0002]
[Prior art]
Conventionally, as an assist grip mounting structure of this type, for example, as disclosed in US Pat. No. 4,981,322, a mounting seat is provided on a grip body, and this mounting seat is used as a vehicle body panel (fixed body). There is known a structure that is fixed to. In this case, a pair of locking pieces to be inserted into the mounting holes of the vehicle body panel is formed on the mounting seat, and when fixing the mounting seat, a lock pin is inserted between the locking pieces inserted into the mounting holes. The interval between the locking pieces is widened so that the locking claw provided on the front end side of the locking piece is locked to the peripheral edge of the mounting hole of the vehicle body panel. The assembling work can be easily and quickly performed only by inserting the lock pin.
[0003]
Further, in the above conventional example, the lock grip is held in the temporary holding position inserted halfway between the locking pieces of the mounting seat, and then the assist grip is carried into the vehicle body assembly line, whereby the assist grip is assembled in the assembly line. The effort is further reduced.
[0004]
[Problems to be solved by the invention]
By the way, if the lock pin is carried into the vehicle assembly line with the lock pin held in the temporary holding position as in the above-described conventional example, the lock pin is completely pushed in before being assembled to the vehicle body or falls off the mounting seat. There are things to do. In other words, if the holding force of the locking piece to the lock pin at the temporary holding position of the lock pin is not sufficient, the lock pin is completely pushed in and the locking claw portion extends beyond the opening size of the mounting hole. Therefore, the assist grip cannot be attached as it is, and it takes time to pull out the lock pin. In addition, the lock pin may fall off the mounting seat and be lost.
[0005]
On the other hand, if the lock pin is sandwiched and held with a sufficiently strong force by the latching piece at the temporary holding position, when the lock pin is pushed in at the time of assembly, a large force against the sliding resistance between the latching piece and the lock pin is obtained. Since this is necessary, there is a problem that the assembly workability deteriorates.
[0006]
The present invention has been made in view of such various points, and an object of the present invention is to provide a mounting seat of an assist grip with a pair of locking pieces to be inserted into mounting holes of a fixed body, and the locking pieces. When inserting the lock pin in between and attaching the mounting seat to the fixed body, while preventing the lock pin in the temporary holding position from being pushed in or coming off before assembling the assist grip to the fixed body, In order to improve the workability during assembly.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, in the solution means of the present invention, a temporary holding holding portion for holding the lock pin in the temporary holding position is formed in one locking piece, and the temporary holding position is formed in the other locking piece. An abutting portion that abuts against the other side surface of the lock pin is formed so that the lock pin is not in contact with the locking piece when inserted deeper than the temporary holding position.
[0008]
Specifically, in the first aspect of the invention, the mounting seat for attaching the grip body of the assist grip to the fixed body and the back surface of the mounting seat are integrally spaced from each other so as to be inserted into the mounting hole of the fixed body. A pair of locking pieces each provided with a locking claw that extends and protrudes away from each other, and a plate-like lock pin is inserted between the pair of locking pieces so as to widen the gap between them Thus, the assist grip mounting structure in which the locking claw is locked to the peripheral edge of the mounting hole is assumed. Then, one locking piece of the pair of locking pieces is engaged with an engaging portion formed on one side surface of the lock pin, and the lock pin is inserted to the main fixing position of the mounting seat. A temporary holding holding portion is formed at the temporary holding position in front, and the other locking piece is provided with a contact portion protruding so as to contact the other side surface of the lock pin at the temporary holding position. A step surface that is formed in opposition to the vicinity of the engaging portion of the pin and that is not in contact with the abutting portion on the other side surface of the locking pin with the locking pin being inserted deeper than the temporary holding position. It is set as the structure which forms.
[0009]
According to this configuration, when the lock pin is inserted between the pair of locking pieces extending from the mounting seat of the grip body, first, the temporary holding holding portion of one locking piece and the one side surface of the locking pin are formed. Thus, the lock pin is held at the temporary holding position before the lock pin is inserted to the main fixing position of the mounting seat by one of the locking pieces. At this time, the other side surface of the lock pin is abutted and supported by the abutting portion formed on the other locking piece so as to oppose the vicinity of the engaging portion of the lock pin. The holding portion can be firmly engaged, so that the lock pin can be held with a sufficiently strong force. Therefore, for example, even if the lock pin is held on the mounting seat in the temporary holding position and then the assist grip is carried to the mounting position on the fixed body, the lock pin is pushed in before the mounting, or the mounting seat You will not fall out of it.
[0010]
When the assist grip is assembled to the fixed body, the pair of locking pieces of the mounting seat are inserted into the mounting holes of the fixed body, and then the lock pin at the temporary holding position is pushed in and inserted. At this time, if the lock pin is inserted deeper than the temporary holding position, the other side surface of the lock pin is not in contact with the contact portion of the other locking piece. On the other hand, the sliding resistance with the contact portion does not act, and the operation can be easily performed.
[0011]

It consists of a rectangular plate-shaped pin portion 65 extending so as to be inserted therebetween. The lid portion 64 is formed in a shape corresponding to the shape of the end surface on the vehicle interior side of the fixed portion 8, while the pin portion 65 is substantially parallel to the locking pieces 53, 54 and the tips of the locking pieces 53, 54. It is formed to extend long toward the side. As shown in FIG. 15, rectangular cross-section ribs projecting from the side surface 65 a (one side surface) on the first locking piece 53 side at both ends of the pin portion 65 in the width direction (longitudinal direction of the grip body 1). 66, 66 are provided. The front end surfaces of the ribs 66, 66 in the protruding direction are flat surfaces substantially parallel to the pin side surface 65a. The ribs 66 are connected to the lid portion 64 on the proximal end side of the pin portion 65, and are connected to each other by a connecting portion 67 that bulges from the pin portion side surface 65 a on the distal end side of the pin portion 65. A groove portion 67 a (engagement portion) having a V-shaped cross section is formed at the tip portion of the pin portion 65 of the connecting portion 67 over the entire width direction of the pin portion 65.
[0022]
On the other hand, as shown in FIG. 16, the side surface 65 b (the other side surface) of the pin portion 65 on the second locking piece 54 side is the same as the ribs 66 and 66 of the side surface 65 a on the first locking piece 53 side. Ribs 68 and 68 are formed, and a notch 70 having a cross section similar to that of the groove 67a is formed at the tip end side of the pin portion 65 of the ribs 68 and 68. Further, the pin portion of the notch 70 is formed. The inclined surface which is closer to the pin side surface 65b is connected to the distal end side of the 65. And the dimension from the protrusion direction front-end | tip of the rib 66 by the side of the 1st latching piece 53 in the pin part 65 to the protrusion direction front-end | tip of the rib 68 by the side of the 2nd latching piece 54 is the dimension of said two latching pieces 53,54. It is substantially the same as the separation distance. Further, as a feature of the present invention, as shown in FIG. 17, a stepped portion 69 is formed at a substantially central portion between the proximal end and the distal end of the side surface 65 b of the pin portion 65. In the side surface 65b on the second locking piece 54 side, the portion from the base end to the substantially central portion in the longitudinal direction of the pin portion 65 is located closer to the other side surface 65a of the pin portion 65 than the portion from there to the tip end. Such a stepped surface 65c is formed. Further, on both end faces in the width direction of the pin portion 65, ridge portions 71, 71 extending from the proximal end side to the distal end side of the pin portion 65 are formed, respectively, and when the lock pin 60 is inserted, The protrusions 71, 71 are in sliding contact with guide portions 72, 72 (see FIGS. 11 and 12) provided between the first and second locking pieces 53, 54 on the inner peripheral surface of the fixed portion 8. Guided.
[0023]
As shown in FIGS. 5 and 6, the support portion 11 of the mounting seat 6 has a bottomed cylindrical shape that is long in the left-right direction (the length direction of the grip body 1) as a whole. A support shaft 12 protruding from the side surface is integrally formed on one side surface of the grip body 1 facing the bearing portion 3, and the tip end portion of the support shaft 12 rotates in the bearing hole 4 of the bearing portion 3. It is inserted as possible. Thus, the grip body 1 is rotatably supported on the support shaft 12 of the mounting seat 6 by the bearing portion 3 of the leg portion 1a.
[0024]
On the other hand, on the other side surface of the support portion 11 of the mounting seat 6, a bottomed recess 13 having a tapered hole whose inner diameter gradually decreases toward the support shaft 12 is formed concentrically with the support shaft 12. In addition, a tapered insertion shaft 14 extending concentrically with the support shaft 12 is provided from the bottom 13b of the recess 13 toward the opening side. In other words, the concave portion 13 is opened to the outer side wall 3a side of the housing portion 2. In addition, a substantially bottomed cylindrical spacer 18 is fixedly attached to the spacer mounting hole 5 of the leg 1a so as not to rotate, and the tip of the spacer 18 can be rotated into the recess 13 of the support portion 11. Has been inserted. That is, the distal end portion of the spacer 18 includes a tapered tapered insertion portion 19 and a relatively large diameter large diameter portion 20 that is continuous in a step shape on the proximal end side of the insertion portion 19. It is inserted into the concave portion 13 of the support portion 11, and a substantially constant gap is formed between the outer peripheral surface of the insertion portion 19 and the inner peripheral surface of the concave portion 13 in the inserted state.
[0025]
The large-diameter portion 20 is fitted in the opening 13a of the recess 13 of the support portion 11. The large-diameter portion 20 allows the opening 13a of the recess 13 to be relatively rotated, and the spacer 18 is large. An O-ring 21 is interposed between the diameter portion 20 and the opening portion 13a of the concave portion 13, and a gap between the outer peripheral surface of the insertion portion 19 and the inner peripheral surface of the concave portion 13 described later, and the inner peripheral surface of the fitting portion 29, The flow of the viscous agent L filled in the clearance between the insertion shaft 14 and the outer peripheral surface of the support portion 11 is prevented.
[0026]
The base end portion 22 of the spacer 18 has an outer diameter shape substantially the same as the spacer mounting hole 5 in the leg portion 1 a of the grip body 1 described above, and the base end portion 22 is fitted in the spacer mounting hole 5. Thus, the rotation of the leg 1a around the axis of the spacer 18 with respect to the outer side wall 3a is prevented, that is, the leg 1a is rotated integrally with the grip body 1.
[0027]
Further, the intermediate portion of the spacer 18 connecting the base end portion 22 of the spacer 18 and the insertion portion 19 has four intermediate connecting portions 23, 24, 25, and 26 (23 and 24 are shown in FIG. 5) extending in the axis X direction. Further, 23, 25, and 26 are shown in FIG. 6), and the outer peripheral portions of the intermediate connecting portions 23, 24,... Are paired at positions opposed to each other in the diameter direction of the spacer 18. A claw 27 is protruded. When the spacer 18 is inserted into the spacer mounting hole 5, the retaining claws 27, 27,... Are locked to the side surface of the outer side wall 3 a of the accommodating portion 2 of the leg portion 1 a, so that the spacer 18 is mounted on the spacer 18. It is designed to prevent the hole 5 from coming off.
[0028]
Further, an insertion portion 29 is formed in the insertion portion 19 of the spacer 18. The insertion portion 29 is formed of a tapered bottomed hole having a small diameter on the proximal end side from the distal end surface toward the proximal end side. Inside the insertion portion 29, the insertion shaft 14 of the support portion 11 is inserted so that the spacer 18 can rotate. In this insertion state, the outer peripheral surface of the insertion shaft 14 and the insertion portion are inserted. A gap is formed between the inner peripheral surface of the insertion shaft 29 and a clearance between the tip surface of the insertion shaft 14 and the bottom surface 29 a of the insertion portion 29. The gaps communicate with each other, and the outer peripheral surface of the insertion portion 19 and the inner peripheral surface of the recess 13 are interposed via a gap between the tip surface of the insertion portion 19 of the spacer 18 and the bottom surface 13b of the recess 13. The four continuous gaps are filled with a viscous agent L having a high viscosity (preferably 100000 cps or more) such as silicon. Thereby, the viscous damper 16 which provides viscous resistance to rotation of the grip body 1 is configured.
[0029]
Here, as shown in FIGS. 5 and 6, the insertion portion 19 on the distal end side of the spacer 18 is inserted into the recess 13 of the support portion 11, and the insertion shaft of the support portion 11 is inserted into the insertion portion 29 in the insertion portion 19. 14 is inserted, the gap α between the distal end surface of the insertion portion 19 of the spacer 18 and the bottom surface 13b of the concave portion 13 of the support portion 11 is equal to the bottom surface 29a of the insertion portion 29 in the insertion portion 19 of the spacer 18. It is larger than the gap β between the front end surface of the insertion shaft 14. In other words, the length of the spacer 18, the depth of the insertion portion 29, the depth of the concave portion 13 of the support portion 11, the length of the insertion shaft 14, etc., and the positional relationship between these portions are determined by the clearance α Is set to be larger than the gap β, which will be described in detail later. This prevents air from remaining in the gap when the spacer 18 is attached to the mounting seat 6. it can.
[0030]
On the other hand, the other mounting seat 7 is different from the mounting seat 6 only in the support structure for the leg 1b of the grip body 1, as shown in FIGS. It is supported by a support shaft 31. In the following description, the same reference numerals are given to the same components in the mounting seat 7 as those of the mounting seat 6, and the detailed description thereof is omitted. And in the said leg part 1b, as shown in FIG. 7, both the left and right both side walls (two side walls which oppose the length direction of the grip main body 1) of the accommodating part 2 are made into the bearing parts 3 and 3, respectively. A bottomed bearing hole 4 a is formed on the inner surface of the left bearing portion 3, and a through-hole bearing hole 30 is formed concentrically on the right bearing portion 3.
[0031]
In the mounting seat 7, a support portion 32 is formed integrally with the fixed portion 8 in the same manner as the support portion 11 of the mounting seat 6. The support portion 32 has a substantially cylindrical shape that is long in the left-right direction (the length direction of the grip body 1) as a whole, and shaft insertion holes 33 and 34 (shown only in FIG. 7) on the left and right side wall portions, respectively. Are formed concentrically. The support shaft 31 is supported through the shaft insertion holes 33 and 34, and both end portions of the support shaft 31 protrude outward from the left and right sides of the support portion 32 to form the housing portion 2. The bearing holes 4 a and the bearing holes 30 are inserted into the bearing holes 4 a and 3. With this configuration, the grip body 1 is supported by the support shaft 31 so as to be rotatable around its center line (axis X) with respect to the support portion 32 of the mounting seat 7.
[0032]
In addition, a torsion coil spring 17 is disposed around the intermediate portion in the longitudinal direction of the support shaft 31. That is, a coil spring storage space 32a having a substantially circular cross section that is long in the length direction of the grip body 1 is formed inside the support portion 32 of the mounting seat 7, and the torsion coil spring 17 is stored in the storage space 32a. ing. In other words, the support portion 32 of the mounting seat 7 is a coil spring body housing portion that houses the torsion coil spring 17. The length of the storage space 32 a in the support portion 32 in the length direction is larger than the length of the torsion coil spring 17, while the diameter of the storage space 32 a is slightly larger than the diameter of the torsion coil spring 17. Thus, the torsion coil spring 17 is movable in the length direction in the storage space 32a in a state in which the center line substantially coincides with the axis X.
[0033]
More specifically, a coil spring insertion port 35 is formed in the peripheral wall of the support portion 32 over a predetermined range that faces downward when the mounting seat 7 is fixed to the vehicle body panel P, and the coil spring insertion port. A first slit 36 extending in the circumferential direction through the peripheral wall on the opposite side of 35, and a second slit extending in the length direction of the support portion 32 (the length direction of the grip body 1) continuously from the first slit 36. A slit 37 is formed. That is, as shown in FIG. 8, when viewed from the insertion direction of the torsion coil spring 17, the coil spring insertion port 35 has a substantially rectangular shape, and is approximately the same size as the coil spring storage space 32a in its length direction and width direction. ing.
[0034]
In addition, the first slit 36 extends from the storage space 32a (inside the coil spring storage portion) in the support portion 32 to the peripheral wall of the support portion 32 that becomes a boundary wall with the fixing portion 8 in the mounting seat 7. While penetrating to the inside (outside of the coil spring housing portion), the circumferential direction (vertical direction in FIG. 8) along the inner surface (the surface facing the housing space 32a) of one side wall (the left side wall in FIG. 8) of the support portion 32. It extends to. The second slit 37 extends from the end of the first slit 36 (upper end in FIG. 8) to the middle in the length direction of the support 32, and the support 32 is the same as the first slit 36. The opening width (the width in the vertical direction in FIG. 8) gradually decreases from the storage space 32a toward the fixed portion 8 side. The first and second slits 36 and 37 are substantially L-shaped continuously from the coil spring insertion direction.
[0035]
The torsion coil spring 17 has an extension portion 17a in which a wire is extended outward from the outer periphery of one end portion in the length direction (left end portion in FIG. 7), and the distal end side of the extension portion 17a is bent. Thus, a bent portion 17b is formed. The length of the bent portion 17b is shorter than the length of the first slit 36 (the length in the vertical direction in FIG. 8), and the torsion coil spring 17 is connected to one side in the length direction of the support portion 32 (FIG. 7). The bent portion 17b easily passes through the first slit 36 when inserted into the coil spring insertion port 35 in a state of being moved to the left side of FIG. Further, the torsion coil spring 17 is stored in the storage space 32a with the other end portion in the length direction (the right end portion in FIG. 7) approaching the inner surface of the right side wall of the support portion 32 (storage position). In this state, the extension portion 17a of the torsion coil spring 17 passes through the second slit 37, and the bent portion 17b on the tip side thereof is in the peripheral portion of the second slit 37 in the space portion 8a of the fixed portion 8. It is locked.
[0036]
A wire rod is also extended outward from the outer periphery of the other end of the torsion coil spring 17 to form an extension portion 17c. The extension portion 17c is an inner bottom wall (see FIG. 2 is engaged with a groove 38 formed in the lower wall). Then, the torsional force of the torsion coil spring 17 causes the grip body 1 to be urged to rotate in the direction from the use position toward the storage position (counterclockwise in FIGS. 2 to 4) so that the grip body 1 is always positioned at the storage position. Yes.
[0037]
As shown in FIGS. 2 to 4, a contact portion 39 is formed at each open end of the accommodating portion 2 on the distal end side of each leg portion 1 a, 1 b of the grip body 1, A stopper portion 40 that can abut against the abutting portion 39 is formed on the fixing portion 8 of each mounting seat 6, 7. Then, when the grip body 1 is rotated from the storage position to the use position, the contact portions 39 of both the leg portions 1a and 1b come into contact with the stopper portions 40 of the mounting seat 6, respectively. The above rotation is restricted and stopped at the use position.
[0038]
(Assembly of assist grip)
Next, a procedure for assembling the assist grip G having the above-described configuration will be described. First, with respect to the mounting seat 6, the support shaft 12 is inserted into the bearing hole 4 of the bearing portion 3 in the leg portion 1 a of the grip body 1, and the support portion 11 is housed in the housing portion 2. The spacer 18 is inserted into the spacer mounting hole 5 in the leg portion 1 a from the tip side, the insertion portion 19 is inserted into the recess 13 of the support portion 11, and the insertion shaft 14 of the support portion 11 is inserted into the insertion portion 29. . Thereby, the retaining claw 27 of the spacer 18 is locked to the side surface (side surface of the outer side wall 3a) of the accommodating portion 2 of the leg portion 1a, and the proximal end side of the spacer 18 is fixed to the leg portion 1a. If a necessary amount of the viscosity agent L is filled in the insertion portion 29 of the spacer 18 in advance before the assembly of the spacer 18, the insertion shaft that enters the insertion portion 29 simultaneously with the assembly of the spacer 18. The viscous agent L is pushed out by 14 and spreads and filled in the gap in the recess 13.
[0039]
More specifically, as shown in FIG. 9, a necessary amount of the viscous agent L is previously placed in the insertion portion 29 of the spacer 18, and the insertion portion 19 of the spacer 18 is attached to the spacer of the leg portion 1 a of the grip body 1. It passes through the hole 5 and is inserted along the axis X into the recess 13 that opens in the support portion 11 of the mounting seat 6. At this time, the insertion shaft 14 extending from the bottom surface 13 b toward the opening 13 a in the recess 13 is inserted into the insertion portion 29 of the spacer 18.
[0040]
Then, as shown in FIG. 10, when the spacer 18 is inserted into the spacer mounting hole 5 to the proximal end side, the insertion portion 19 of the spacer 18 is inserted to the back side of the concave portion 13 of the mounting seat 6. Accordingly, the insertion shaft 14 of the recess 13 is inserted into the back side of the insertion portion 29 of the spacer 18 to push out the viscous agent L in the insertion portion 29. In this way, the viscous agent L is pushed out from the gap between the inner peripheral surface of the insertion portion 29 and the outer peripheral surface of the insertion shaft 14, and between the distal end surface of the insertion portion 19 of the spacer 18 and the bottom surface 13 b of the concave portion 13. Is further pushed from there into the gap between the outer peripheral surface of the insertion portion 19 of the spacer 18 and the inner peripheral surface of the recess 13, and the gap moves toward the opening 13 a of the recess 13.
[0041]
Thus, when the insertion portion 19 of the spacer 18 is inserted to the deepest portion of the concave portion 13 of the support portion 11, the distance α between the front end surface of the spacer 18 and the bottom surface 13 b of the concave portion 13 is the insertion of the spacer 18. Since the interval β between the bottom surface 29 a of the portion 29 and the tip end surface of the insertion shaft 14 is larger, the tip end surface of the insertion shaft 14 is in contact with or just before the bottom surface 29 a of the insertion portion 29. The viscous agent L inside is sufficiently pushed out, and the extruded viscous agent L discharges almost all the air in the recess 13.
[0042]
Thus, the spacer 18 passes through the gap between the outer peripheral surface of the insertion portion 19 of the spacer 18 and the inner peripheral surface of the concave portion 13 of the support portion 11 via the gap between the front end surface of the spacer 18 and the bottom surface 13b of the concave portion 13. 18 continuous to the gap between the inner peripheral surface of the insertion portion 29 and the outer peripheral surface of the insertion shaft 14, and further to the entire gap that continues to the clearance between the bottom surface 29 a of the insertion portion 29 and the front end surface of the insertion shaft 14. As the viscous agent L is filled, almost all of the air is discharged from the gap, that is, the recess 13.
[0043]
On the other hand, for the mounting seat 7, the torsion coil spring 17 is first housed in the support portion 32 of the mounting seat 7, and then the mounting seat 7 is assembled to the leg portion 1 b of the grip body 1. That is, first, as shown in FIG. 11A, the torsion coil spring 17 is moved to the left side of the drawing with respect to the coil spring insertion port 35, that is, one end of the torsion coil spring 17 is connected to the support portion 32. Insert so as to be in sliding contact with the inner surface of the left side wall. Then, as shown in FIG. 12 (a), the extension 17a of the torsion coil spring 17 enters the storage space 32a from the coil spring insertion port 35, and is further inserted through the first slit 36. In FIG. As shown, the distal end side of the extension portion 17 a of the torsion coil spring 17 protrudes into the space portion 8 a outside the support portion 32, so that the bent portion 17 b is positioned in the space portion 8 a of the fixed portion 8.
[0044]
Subsequently, as shown by a solid line in FIG. 11 (b), the torsion coil spring 17 is shifted in the length direction to the storage position, and the other end of the torsion coil spring 17 contacts the inner surface of the right side wall of the support portion 32. Make contact. In this way, the extension portion 17a moves in the second slit 37, and the bent portion 17b at the tip thereof is locked to the peripheral edge portion of the second slit 37 facing the space portion 8a. The torsion coil spring 17 is held in the storage space 32a with its center line substantially coincident with the axis X. That is, the torsion coil spring 17 can be easily stored and held in the storage space 32a simply by inserting the torsion coil spring 17 from the coil spring insertion port 35 into the storage space 32a and shifting it in the length direction. In FIG. 11 (b), in order to clarify the mounting seat 7 in which the torsion coil spring 17 is accommodated, a part of the support portion 32 is notched.
[0045]
When attaching the mounting seat 7 containing the torsion coil spring 17 to the leg 1b of the grip body 1 in this way, the top and bottom of the mounting seat 7 is reversed from the state shown in FIG. The support portion 32 of the mounting seat 7 is inserted into the accommodating portion 2 of the leg portion 1b of the grip body 1 from above, and at the same time, the extension portion 17c of the torsion coil spring 17 is inserted into the groove portion 38 of the leg portion 1b of the grip body 1. Lock. At this time, the shaft insertion holes 33 and 34 on the left and right side walls of the support portion 32 of the mounting seat 7 and the bearing holes 4a and the bearing holes 30 of the left and right bearing portions 3 and 3 of the housing portion 2 in the leg portion 1b of the grip body 1 are used. Are positioned substantially concentrically with each other, and the torsion coil spring 17 is also positioned substantially concentrically with each other. In this state, the distal end side of the support shaft 31 is moved away from the through-hole bearing hole 30 of the leg portion 1b. Inserted toward the bearing hole 4 a, the support shaft 31 passes through the shaft insertion holes 33 and 34 of the mounting seat 7 and the torsion coil spring 17, and the tip of the support shaft 31 is connected to the other bearing portion 3. The bottom bearing hole 4a is fitted and fixed. Note that the base end side of the support shaft 31 may be fixed by being secured in the bearing hole 30 by a snap ring or the like.
[0046]
After the mounting seats 6 and 7 are assembled to the leg portions 1a and 1b of the grip body 1 as described above, the fixing portions 8 of the mounting seats 6 and 7 are fixed to the vehicle body panel P. That is, first, as shown in FIG. 14, the lock pin 60 is held at the temporary holding position on each fixing portion 8 of the mounting seats 6 and 7 of the assist grip G. At this time, when the lock pin 60 is inserted between the first and second locking pieces 53, 54 from the proximal end side of the locking pieces 53, 54, the tip inclined surface of the connecting portion 67 of the pin portion 65 is the first engaging surface. The temporary holding position engaging portion 61 of the stopper 53 is moved over the temporary holding position engaging portion 61 so that the temporary holding position engaging portion 61 is positioned in the groove 67a of the connecting portion 67, and the both are engaged. Of the side surface 65b on the locking piece 54 side, the tip surface of the protrusions 63, 63 of the second locking piece 54 comes into contact with the side surface 65b on the tip side from the stepped portion 69, so that the pin portion 65 is connected to the first locking piece. The lock pin 60 can be held with a sufficiently strong force.
[0047]
Thus, when the lock pin 60 is in the temporary holding position, the protrusions 63, 63 are provided in the vicinity of the temporary holding position engaging portion 61 of the first locking piece 53, thereby providing the protrusion 63. , 63 securely presses the side surface 65b of the pin portion 65 toward the temporary holding position engaging portion 61, so that the groove portion 67a and the temporary holding position engaging portion 61 are firmly engaged without being disengaged. Become. In this state, since only the distal end side of the lock pin 60 is inserted, the separation distance between the distal end sides of both the locking pieces 53 and 54 remains the predetermined distance.
[0048]
Next, the assist grip G holding the lock pin 60 in the temporary holding position as described above is carried into the vehicle body assembly line, and the flanges 50 of the mounting seats 6 and 7 are joined to the trim member 52 in the vehicle interior. Position at the mounting position. Specifically, when the locking pieces 53 and 54 of the mounting seats 6 and 7 are positioned on the vehicle compartment side of the mounting hole 55 of the vehicle body panel P and the mounting seats 6 and 7 are pressed in the insertion direction, they contact the peripheral edge of the mounting hole 55. The locking pieces 53 and 54 are elastically deformed so that the locking claw portions 56 and 57 approach each other, and the locking claw portions 56 and 57 penetrate the mounting hole 55. After that, the locking pieces 53 and 54 return to the state separated by the predetermined distance due to their elastic force and are prevented from being detached from the mounting holes 55 of the mounting seats 6 and 7, while The parts 51 and 51 are in contact with the vehicle body panel P.
[0049]
After positioning the assist grip G (mounting seats 6 and 7) in this way, when the lid portion 64 of the lock pin 60 is pressed, the groove portion 67a of the connecting portion 67 of the pin portion 65 is formed as shown in FIG. The lock pin 60 is moved from the temporary holding position engaging portion 61 in the insertion direction. Immediately after this, the protruding portions 63 and 63 of the second locking piece 54 correspond to the step surface 65 c of the pin portion 65. Become. That is, when the lock pin 60 is inserted deeper than the temporary holding position, the side surface 65b of the pin portion 65 is not in contact with the projecting portions 63, 63 (non-contact state). When inserting deeply, the sliding resistance between the protrusions 63 and 63 does not act on the lock pin 60, so that the force during insertion can be reduced.
[0050]
Then, when the lock pin 60 is further inserted, the inclined front ends of the ribs 66, 66, 68, 68 of the pin portion 65 are fixed position engaging portions 58, 58, 62 of the locking pieces 53, 54, respectively. , 62 and the two locking pieces 53, 54 are elastically deformed so as to widen the distance between the two locking pieces 53, 54 at the front end side. It is completely inserted to the fixed position, and the fixed position engaging portion 58 and the groove portion 67a of the pin portion 65 are engaged, while the fixed position engaging portion 62 and the notch portion 70 of the pin portion 65 are engaged, Both the locking pieces 53 and 54 hold the lock pin 60 in the main fixing position. In this state, the base-side inclined surfaces of the locking claws 56 and 57 of both locking pieces 53 and 54 come into contact with the peripheral edge of the mounting hole 55 from the back side of the vehicle body panel P, thereby the mounting seat 6 , 7 are fixed to the vehicle body panel P.
[0051]
Therefore, when the assist grip G configured as described above is assembled to the vehicle body, first, the lock pin 60 is inserted into the mounting seats 6 and 7 of the grip body 1 to the temporary holding position and is held by the first locking piece 53. Then, the assist grip G is carried into the vehicle body assembly line. At that time, since the lock pin 60 is pressed against the first locking piece 53 side by the protrusions 63 and 63 of the second locking piece 54, it does not come off from the first locking piece 53, and the assist grip G It is possible to prevent the lock pin 60 from being completely pushed in before being attached or coming off from the attachment seats 6 and 7.
[0052]

At this time, since the step surface 65c is formed on the second locking piece 54 side of the lock pin 60, when the lock pin 60 in the temporary holding position is inserted deeper than the temporary holding position, Since the protrusions 63 and 63 of the locking piece 54 are not in contact with each other, the lock pin 60 can be inserted with a small force, and the assembly work of the assist grip G can be facilitated.
[0053]
That is, according to this embodiment, after positioning the assist grip G, the mounting seats 6 and 7 can be firmly fixed to the vehicle body panel P simply by pushing the lock pin 60 in the temporary holding position. Compared to this, the assembly work can be performed easily and quickly.
[0054]
Further, in this embodiment, the fixed position engaging portions 58 and 62 that receive a large force from the lock pin 60 to expand between the locking pieces 53 and 54 are positioned in the vicinity of the locking claws 56 and 57. The claw portions 56 and 57 can be pressed relatively strongly against the peripheral edge portion of the mounting hole 55, and thus the mounting strength of the assist grip G can be sufficiently secured while facilitating the assembly work as described above.
[0055]
Note that the assist grip mounting structure according to the present invention is not limited to that for a vehicle as in the above embodiment, and is integrated with the mounting seats 6 and 7 in a state where the grip body 1 is in the use position. The present invention may be applied to a molded fixed assist grip.
[0056]
【The invention's effect】
As described above, according to the assist grip mounting structure according to the present invention, the grip body mounting seat is provided with a pair of locking pieces to be inserted into the mounting holes of the fixed body, and one locking piece has a lock pin. A temporary holding holding portion is formed that engages with an engaging portion on one side surface and holds the lock pin at a temporary holding position before the lock pin is inserted to the final fixing position, and the other locking piece is in the temporary holding position. An abutting portion (protruding portion) that abuts on the other side surface of the lock pin is formed to face the vicinity of the engaging portion of the lock pin, and the lock pin is deeper than the temporary holding position on the other side surface of the lock pin. By forming a stepped surface that does not abut against the abutting part in the inserted state, the other side surface of the lock pin inserted to the temporary holding position is supported by the abutting part between the pair of locking pieces. Hold the lock pin firmly with the holding part for temporary holding For example, even if the lock pin is held on the mounting seat in the temporary holding position and then the assist grip is carried to the place where it is attached to the fixed body, the lock pin in the temporary holding position is pushed in or falls off. This can be prevented beforehand. Further, when the lock pin in the temporary holding position is inserted deeply, the lock pin and the contact portion are not in contact with each other, and the assembly work can be easily performed.
