Description

【0001】
【発明の属する技術分野】
本発明はクランプのロック構造に関し、詳細には、クランプを構成するベース部材とカバー部材とを車体に共締めするクランプのロック構造に関する。
【0002】
【従来の技術】
従来、車体にスライドドアが設けられた自動車では、スライドドア内の電装部品と電源とを接続するために、その車体とスライドドア間に渡ってワイヤハーネスが設けられている。ワイヤハーネスは、その一端が車体側に、他端がスライドドア側に固設されるため、ドアが車体の前後方向にスライドするのに伴って、車体側のドア近傍の位置で捻れてしまう可能性がある。そのため、車体側のドア開口部近傍には、図4に示すように、ワイヤハーネス135を自由に回転可能にするための回転部材140を格納したクランプ150が設けられている。ワイヤハーネス135は、蛇腹形状を有する円筒形のコルゲートチューブ136によって覆われた状態となっており、コルゲートチューブ136が円筒形の回転部材140の内側面140aに密接することで、コルゲートチューブ136を介して回転可能となっている。クランプ150は、上部のカバー部材105と下部のベース部材110とを嵌合させることで構成される。カバー部材105は、上に凸型の半円弧断面を有する上壁105aと、上壁105aの図4における左右端部からそれぞれ下方に垂設された左右側壁105b,105cとから構成されている。
【0003】
また、ベース部材110は、底壁110aと、底壁110aの図4における左右端部からそれぞれ上方に突設された左側壁110b、右側壁110cとから構成されており、断面が上方に向かって略円弧形状に開口した形状となっている。ベース部材110は、その底壁110aから右側に延設されたベース固定部材110dをさらに備えている。そして、ベース固定部材120dに穿設されたボルト挿入孔121に嵌装された樹脂カラー170にボルト180を挿入し、さらにボルト180を車体側の取り付け板160に設けられたナット161に螺入して、ベース部材110を車体に固設する。また、カバー部材105の左右側壁105b,105cのそれぞれの下端部には、先端に係止突起108が設けられた係止爪107が形成されており、ベース部材110の左右側壁110b,110cには、係止突起108が係合する係合部112が設けられている。そして、係止突起108が係合部112に係合することにより、カバー部材105とベース部材110とが組み付けられてクランプ150が構成され、クランプ150内で、回転部材140を介してワイヤハーネス135が回転可能となっている。
【0004】
【発明が解決しようとする課題】
しかしながら、上記の従来技術では、カバー部材105に形成された係止爪107先端の係止突起108と、ベース部材110に設けられた係合部112とを係合させるために、係止突起108と係合部112との係合後に所定の隙ができるように形成されているので、係合後にカバー部材105とベース部材110とががたついて、クランプ150内の回転部材140が滑らかに回転できないという問題があった。
【0005】
本発明は、上記課題を解決するためになされたものであり、クランプ内の回転部材を滑らかに回転させられるクランプのロック構造を提供することを目的とする。
【0006】
【課題を解決するための手段】
上記目的を達成するために、請求項1に係る発明のクランプのロック構造は、自動車の車体に設けられ、ワイヤハーネスが収納されているコルゲートチューブの外周方向側に密接して設けられた回転部材を回転可能な状態で保持するクランプを構成するベース部材とカバー部材とを嵌合させるクランプのロック構造であって、前記カバー部材は、上壁と当該上壁から前記ベース部材の側面に沿って延設された側壁とを備え、当該側壁には先端に係止突起を有する係止爪を形成し、前記上壁からは、前記ベース部材に固定するためのカバー固定部材を前記側壁と平行に延設し、さらに、当該カバー固定部材には、前記カバー部材と前記ベース部材とを前記車体に固設するためのボルトが挿入されるボルト挿入孔にカラーが嵌装された筒状突起を下方に向けて凸設し、前記ベース部材は、底壁と当該底壁から延設された側壁とを備え、当該側壁の外側面には、前記係止突起が係合する係合部を設け、前記底壁からは、前記車体に固定するためのベース固定部材を底壁領域外方へ延設し、さらに、当該ベース固定部材には、前記筒状突起が嵌合する貫通孔を穿設し、当該貫通孔に前記筒状突起を嵌合させ、前記ボルト挿入孔にボルトを挿入して、当該ボルトを車体側に設けられたナットに締め付けることにより、前記ベース固定部材と前記カバー固定部材とを共締めして車体に固設することを特徴とする構成となっている。
【0007】
この構成のクランプのロック構造では、カバー部材の側壁に形成した係止爪の先端に係止突起を設けており、当該係止突起をベース部材の側壁に設けた係合部に係合させることにより、カバー部材とベース部材とを嵌合させることができる。また、カバー部材の上壁から前記側壁と平行に延設したカバー固定部材には、ボルト挿入孔にカラーが嵌装された筒状突起を下方に向けて凸設しており、当該筒状突起をベース部材のベース固定部材に穿設した貫通孔に嵌合させて、さらに、ボルト挿入孔にボルトを挿入して、当該ボルトを車体側に設けられたナットに締め付けることにより、ベース固定部材とカバー固定部材とを共締めして車体に固設するようになっている。これにより、ベース部材とカバー部材とのがたつきが防止された状態でクランプが構成されるので、クランプの内部でワイヤハーネスが収納されているコルゲートチューブが、当該コルゲートチューブの外周方向側に密接して設けられた回転部材と共に滑らかに回転することができる。
【0008】
【発明の実施の形態】
以下、本発明を具体化した一実施形態について図面を参照して説明する。ここで、図1は、自動車に設けられたスライド式のドア51が開くことにより形成された車体50の開口部60の後方部分の構造を示す斜視図である。図1に示すように、車体50の前後方向(図1での左右方向)へスライド可能なドア51が設けられた自動車では、ドア51内の電装部品と電源とを接続するために、その車体50とドア51間に渡って、ワイヤハーネス3(図2参照)が設けられている。複数本の導線(図示外)からなるワイヤハーネス3は、蛇腹形状を有する樹脂製のコルゲートチューブ4内に収納されている。ワイヤハーネス3は、その一端が車体50側に、他端がドア51側に固設されるため、ドア51の開閉に伴って車体50とドア51との間で回転したり捻れたりすることがある。そこで、車体50側の開口部60近傍に、ワイヤハーネス3を収納し、ワイヤハーネス3を回転可能に保持することができるクランプ5を設けている。
【0009】
クランプ5は、図1での上側が略蒲鉾型になった略直方体の箱体形状を有し、その長手方向が車体50の車幅方向(図1の奥行き方向)と略平行になるように自動車室内底部の取り付け床部50aに固設されている。そして、コルゲートチューブ4に覆われたワイヤハーネス3は、クランプ5の図1における手前側壁5a及び奥側壁(図示外)、即ちクランプ5の長手方向に対して垂直な2つの壁部を貫通して、ドア51方向に延出している。コルゲートチューブ4に覆われたワイヤハーネス3は、クランプ5の内でクランプ5の長手方向と略平行となっており、クランプ5から出た後、車体50の前後方向に略平行となり、即ちクランプ5内のワイヤハーネス3と略垂直となってドア51方向に延出している。クランプ5内では、コルゲートチューブ4が、その周方向外側に密接して設けられた回転部材2(図2参照)と共に回転可能となっている。そして、ドア51の開閉に伴って、コルゲートチューブ4のクランプ5内に格納された部分を中心として、略垂直に延出したコルゲートチューブ4のドア51側の部分が、車幅方向に対して略垂直な面上で図1の左右方向に回転可能となっている。コルゲートチューブ4に覆われたワイヤハーネス3も、コルゲートチューブ4と同様に、車幅方向に対して略垂直な面上で図1の左右方向に回転可能な状態となる。
【0010】
次に、図2を参照して、クランプ5の構造について説明する。ここで、図2は、図1のA−A線矢視方向断面図である。図2に示すように、クランプ5は、共に合成樹脂材料で一体成型された上側のカバー部材6と下側のベース部材11とから構成されている。カバー部材6は、図2において上に凸型の半円弧形状断面を有する上壁6aと、上壁6aの左右端部から水平方向に僅かに延設された水平部6b,6cと、水平部6bの末端から下方に垂設された左側壁6dと、水平部6cの末端から下方に垂設された右側壁6eとを備えている。また、左右側壁6d,6eには、その下端からさらに下側に延設された係止爪7がそれぞれ形成されている。係止爪7の先端には、後述するベース部材11に設けられた係合部12の係合壁12aに係合する係止突起8が設けられており、係止爪7は、クランプ5の長手方向に対して所定の間隔をおいて複数個形成されている。尚、図示しないが、上壁6aの内側面6a1には、後述する回転部材2の外側面2bに設けられた図示外のリブが嵌合する凹部を形成するリブが、その長さ方向(図2の奥行き方向)に対して所定の間隔で設けられている。
【0011】
さらに、カバー部材6の水平部6cの図2における右側端部からは、右方向に向かってカバー固定部材9が延設されている。カバー固定部材9は、水平部6cから水平方向に延設された水平部9aと、水平部9aの右側端部から下方に向かって垂設された鉛直部9bと、鉛直部9bの下端部からさらに右側に向かって垂設された取り付け足9cとから構成されている。取り付け足9cの底面9c1からは、筒状突起10が下方に凸設されており、当該筒状突起10には、図2の上下方向に貫通して、後述するボルト30が挿入されるボルト挿入孔10aが穿設されている。
【0012】
また、筒状突起10に穿設されたボルト挿入孔10aには、ボルト30とボルト挿入孔10aとのがたつきを防止するための樹脂製のカラー25が予め嵌装されており、カラー25には樹脂製のワッシャ24が一体に設けられている。カラー25は、筒状突起10と略同一高さを持つ円筒形状を有し、所定厚を有するワッシャ24は、カラー25の内径と等しい内径とカラー25の外径よりも大きな外径とを有している。
【0013】
また、ベース部材11は、図1に示すクランプ5の長手方向寸法と等しい長さを有する直方体の上部を蒲鉾型に切り欠いた形状となっており、その底面11a1が車体50側の取り付け床部50aの表面50a1に当接する底壁11aと、当該底壁11aの図2における左右端部からそれぞれ上方に突設された左右側壁11b,11cとを備えている。ベース部材11には、底壁11aと左右側壁11b,11cとによって、断面が図2の上側に略半円型に開口した開口部11dが形成されており、当該略半円型の開口部11dとカバー部材6の上壁6aとで略円形の空間が形成されるようになっている。尚、図示しないが、開口部11dには、後述する回転部材2の外側面2bに設けられた図示外のリブが嵌合する凹部を形成するリブが、その長さ方向(図2の奥行き方向)に対して所定の間隔で設けられている。
【0014】
また、左側壁11bの外側面11b1には、カバー部材6の左側壁6dに形成された係止爪7先端の係止突起8が係合する係合壁12aを備えた係合部12が設けられており、右側壁11cの外側面11c1にも、カバー部材6の右側壁6eに形成された係止爪7先端の係止突起8が係合する係合壁12aを備えた係合部12が設けられている。係合部12は、左右側壁11b,11cに対して略垂直で、係止爪7の水平方向断面を保持する2つの側壁(図示外)と、当該側壁間に、左右側壁11b,11cと略平行になるように渡設され、その底断面12a1に係止突起8を係合させる係合壁12aとから構成されている。そして、左側壁11bの係合部12では、左側壁11bの外側面11b1と、外側面11b1に対して略垂直に凸設された2つの側壁と、当該2つの側壁間に渡設された係合壁12aとに囲まれた領域が、係止爪7が挿入される挿入部22となっている。また、右側壁11cの係合部12にも、係合部12と外側面11c1とにより係止爪7が挿入される挿入部22が同様に形成されている。
【0015】
さらに、ベース部材11の底壁11aの図2における右側端部からは、右方向に向かってベース固定部材13が延設されている。ベース固定部材13は、底壁11aから水平方向に延設された板状部材である。また、ベース固定部材13の底面13aは、底壁11aの底面11a1と連続しており、車体50側の取り付け床部50aの表面50a1に当接することになる。また、ベース固定部材13の図2での右側端部近傍には、カバー部材6のカバー固定部材9から下方に凸設された筒状突起10が嵌合する貫通孔14が穿設されている。
【0016】
次に、図2及び図3を参照して、カバー部材6とベース部材11との組み付け構造及びクランプ5の車体50への取り付け構造について説明する。ここで図3は、カバー部材6のカバー固定部材9に設けられた筒状突起10とベース部材11のベース固定部材13に穿設された貫通孔14との嵌合部分を示す断面図である。図2に示すように、クランプ5を構成するには、まず、ベース部材11の底壁11aと左右側壁11b,11cとによって形成された開口部11dに、断面略円形の筒状の回転部材2を配設する。ここで、回転部材2は、その内側面2aに、複数本の導線(図示外)からなるワイヤハーネス3を覆ったコルゲートチューブ4が密接した状態となっている。また、図示しないが、回転部材2の外側面2bには、複数のリブが長さ方向(図2での奥行き方向)に対して所定の間隔で凸設されており、当該リブが、開口部11dに設けられた図示外のリブにより形成された凹部に嵌合するようになっている。
【0017】
そして、カバー部材6の左側壁6dに形成された係止爪7を、ベース部材11の左側壁11bの外側面11b1に設けられた係合部12に囲まれた挿入部22に挿入し、係止爪7先端の係止突起8を、係合部12の係合壁12aの底断面12a1に係合させ、カバー部材6の右側壁6eに形成された係止爪7を、ベース部材11の右側壁11cの外側面11c1に設けられた係合部12に囲まれた挿入部22に挿入し、係止爪7先端の係止突起8を、係合部12の係合壁12aの底断面12a1に係合させて、カバー部材6とベース部材11とを組み付ける。このとき、回転部材2の外側面2bに設けられたリブ(図示外)が、開口部11dに設けられた図示外のリブにより形成された凹部に嵌合しているのに加え、カバー部材6の上壁6aの内側面6a1に設けられた図示外のリブにより形成された凹部にも嵌合している。従って、回転部材2は、ベース部材11及びカバー部材6に回転可能に保持された状態となっている。
【0018】
また、ベース部材11は、その底壁11aの底面11a1及びベース固定部材13の底面13aが共に車体50側の取り付け床部50aの表面50a1に当接した状態となっている。また、図示しないが、この状態では、ベース部材11の左右側壁11b,11cの上端部に、カバー部材6の上壁6aの左右端部から水平方向に延設された水平部6b,6cが当接しており、ベース部材11に形成された開口部11dとカバー部材6の上壁6aとにより、回転部材2が収納される断面略円形の空間が形成されている。さらに、図3に示すように、ベース部材11のベース固定部材13に穿設された貫通孔14に、カバー部材6のカバー固定部材9に設けられた筒状突起10が嵌合している。
【0019】
また、取り付け床部50aの裏面50a2には、ボルト30が螺入されるナット18が設けられている。また、取り付け床部50aには、ナット18と連通し、取り付け床部50aを貫通した貫通孔19が穿設されている。ベース部材11は、そのベース固定部材13に穿設された貫通孔14が、取り付け床部50aに穿設された貫通孔19と同軸上になるように、取り付け床部50a上に配設される。このとき、カバー固定部材9に設けられた筒状突起10も取り付け床部50aに当接した状態となっており、即ち、カバー固定部材9に設けられた筒状突起10とベース固定部材13に穿設された貫通孔14との嵌合部分においては、ベース固定部材13、筒状突起10及びカラー25の何れもが取り付け床部50aに当接した状態となっている。
【0020】
そして、ボルト30を、筒状突起10のボルト挿入孔10aに嵌装されたカラー25に上方から挿入し、取り付け床部50aの裏面50a2に設けられたナット18に螺入することにより、カバー部材6及びベース部材11が共締めされて、両部材から構成されたクランプ5が車体50側の取り付け床部50aに固設されることになる。クランプ5を構成するカバー部材6とベース部材11とを共締めして車体50に固設することにより、両部材間のがたつきを低減できるので、クランプ5内で、カバー部材6とベース部材11との両部材に回転可能に保持された回転部材2は、保持部材のがたつきにより回転が妨げられるのを防止することができる。従って、ワイヤハーネス3は、コルゲートチューブ4を介して、クランプ5内に配設された回転部材2と共に滑らかに回転することができる。
【0021】
尚、本発明は前記実施の形態に限定されるものではなく、各種の変形が可能である。例えば、本実施の形態では、ワイヤハーネスを回転可能に収納するクランプを、自動車のスライドドア近傍に設けたが、クランプの位置は、不動状態の部材と、該部材に対して相対的に移動可能な部材との間であれば、その取り付け位置が限られることはない。
【0022】
【発明の効果】
以上説明したように、請求項1に係る発明のクランプのロック構造では、カバー部材の側壁に形成した係止爪の先端に係止突起を設けており、当該係止突起をベース部材の側壁に設けた係合部に係合させることにより、カバー部材とベース部材とを嵌合させることができる。また、カバー部材の上壁から前記側壁と平行に延設したカバー固定部材には、ボルト挿入孔にカラーが嵌装された筒状突起を下方に向けて凸設しており、当該筒状突起をベース部材のベース固定部材に穿設した貫通孔に嵌合させて、さらに、ボルト挿入孔にボルトを挿入して、当該ボルトを車体側に設けられたナットに締め付けることにより、ベース固定部材とカバー固定部材とを共締めして車体に固設するようになっている。これにより、ベース部材とカバー部材とのがたつきが防止された状態でクランプが構成されるので、クランプの内部でワイヤハーネスが収納されているコルゲートチューブが、当該コルゲートチューブの外周方向側に密接して設けられた回転部材と共に滑らかに回転することができる。
