Description

【０００１】
【発明の属する技術分野】
本発明は、円筒状の支持パイプに部品を着脱可能に取付けるための部品取付け具に関する。
【０００２】
【従来の技術】
従来、円筒状である支持パイプに部品を固定するための部品取付け具は既に多くのものが実現されているが、支持パイプへの着脱操作の簡略化の観点で満足し得る部品取付け具は実現されていない。
【０００３】
【発明が解決しようとする課題】
本発明は、上記事情に鑑みてなされたものであり、支持パイプへの着脱操作の簡略化を図った部品取付け具を提供することを目的とする。
【０００４】
【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の発明は、円筒状の支持パイプに部品を着脱可能に取付けるための部品取付け具であって、支持パイプの外周の一部に当接される形状に形成されるとともに支持パイプの周方向に沿う一端には被係合部が設けられる第１抱持部材と、支持パイプの軸線と平行な軸線まわりに回動することを可能として第１抱持部材の他端部に基端部が連結される操作レバーと、該操作レバーの回動軸線と平行な軸線まわりの回動を可能として操作レバーの中間部に一端部が連結される中間レバーと、前記操作レバーの回動軸線と平行な軸線まわりの回動を可能として前記中間レバーの他端部に一端部が連結されるとともに第１抱持部材の前記被係合部に係脱可能に係合する係合部が他端に設けられる第２抱持部材とを備え、被係合部に係合部を係合させた第２抱持部材を第１抱持部材と協働して支持パイプを抱持する位置まで回動させる位置に操作レバーを回動操作したときに該操作レバーに弾発的に係合して該操作レバーの回動位置を保持するレバー保持部材と、前記部品を取付けるための取付けボスとが第１抱持部材に設けられ、前記中間レバーは、支持パイプの軸線と平行に延びて第２抱持部材の一端部に回動可能に連結される縦杆部と、該縦杆部の両端に一端を直角に連ならせる一対の横杆部と、両横杆部の他端にそれぞれ設けられて前記操作レバーの中間部に回動可能に連結される連結部とを一体に有し、前記操作レバーには、該操作レバーを前記レバー保持部材に係合させる側に回動したときに、前記両横杆部のうち少なくとも操作レバー側の部分を収納する一対の収納溝が設けられることを特徴とする。
【０００５】
また請求項２の発明は、上記請求項１の発明の構成に加えて、第２抱持部材の一端には、前記縦杆部を回動可能に連結すべく該縦杆部を囲繞する連結筒部が設けられ、第１抱持部材の一端との係合を解除するとともに前記縦杆部の軸線まわりに所定位置まで回動させた第２抱持部材を縦杆部に沿って所定量だけスライドさせるのに応じて前記両横杆部の一方を嵌合させる切欠きが、前記連結筒部の軸方向一端に設けられることを特徴とする。
【０００６】
また請求項３の発明は、上記請求項１又は２の発明の構成に加えて、前記両横杆部のうち各収納溝に対応する部分が各収納溝の側面に摩擦接触するように、前記両横杆部および前記両収納溝が形成されることを特徴とする。
【０００７】
さらに請求項４の発明は、円筒状の支持パイプに部品を着脱可能に取付けるための部品取付け具であって、支持パイプの外周の一部に当接される形状に形成されるとともに支持パイプの周方向に沿う一端には被係合部が設けられる第１抱持部材と、支持パイプの軸線と平行な軸線まわりに回動することを可能として第１抱持部材の他端部に基端部が連結される操作レバーと、該操作レバーの回動軸線と平行な軸線まわりの回動を可能として操作レバーの中間部に一端部が連結される中間レバーと、前記操作レバーの回動軸線と平行な軸線まわりの回動を可能として前記中間レバーの他端部に一端部が連結されるとともに第１抱持部材の前記被係合部に係脱可能に係合する係合部が他端に設けられる第２抱持部材とを備え、被係合部に係合部を係合させた第２抱持部材を第１抱持部材と協働して支持パイプを抱持する位置まで回動させる位置に操作レバーを回動操作したときに、前記支持パイプの軸線に沿う方向での前記操作レバーの中央位置から該軸線に沿う方向の一方側にずれた位置で該操作レバーに弾発的に係合して該操作レバーの回動位置を保持するレバー保持部材と、前記部品を取付けるための取付けボスとが第１抱持部材に設けられることを特徴とする。
【０００８】
請求項１〜４の発明の上記構成によれば、支持パイプを囲むように第１抱持部材、操作レバー、中間レバーおよび第２抱持部材を配置した状態で第１抱持部材の被係合部に第２抱持部材の係合部を係合し、操作レバーを第１抱持部材側に回動操作すると、第２抱持部材がその一端側を第１抱持部材に近接させるようにして係合部の被係合部への係合点を支点として回動し、第１および第２抱持部材で支持パイプが抱持されることになる。この抱持状態は操作レバーにレバー保持部材が弾発的に係合することによって維持される。しかも第１抱持部材に設けられている取付けボスに部品を着脱可能に取付けることで、部品が部品取付け具を介して支持パイプに取付けられることになる。また支持パイプへの取付け状態を解除する際には、レバー保持部材の弾発係合状態を解除する側に操作レバーを回動操作すればよく、そうすれば第１および第２抱持部材による支持パイプの抱持状態が緩められ、係合部の被係合部への係合状態を解除することで部品取付け具を支持パイプから取外すことができ、操作レバーの回動操作によって支持パイプへの取付け、取り外しを容易に行なうことができる。
【０００９】
また特に請求項１の発明の上記構成によれば、支持パイプへの部品取付け具の取付け状態で中間レバーの一部を操作レバー内に収納するので、支持パイプへの取付け状態での部品取付け具をコンパクト化することができる。
【００１０】
また特に請求項２の発明の上記構成によれば、支持パイプから取り外した状態での部品取付け具において、中間レバーおよび第２抱持部材の相対姿勢を一定に保持することができ、部品取付け具の支持パイプへの取付け時に第２抱持部材のぶらつきにより取付け作業に支承を来たすことがなく、円滑な取付け作業を行なうことができる。
【００１１】
また特に請求項３の発明の上記構成によれば、操作レバーの回動操作時に操作力に対抗する摩擦力が中間レバーの両横杆部および操作レバー間で生じることになり、操作レバーの回動操作時に良好な操作フィーリングを得ることができる。
【００１２】
また特に請求項４の発明の上記構成によれば、支持パイプの軸線に沿う方向での操作レバーの幅を大きくしなくても操作レバーに回動操作のための指をかけるスペースを充分に確保することができ、部品取付け具のコンパクト化により一層寄与することができる。
【００１３】

【００２１】
図２および図３を併せて参照して、フロントフォーク２１は、前輪ＷＦを下端部で軸支する円筒状のロアケース３１ならびに該ロアケース３１に嵌合される円筒状の支持パイプとしてのアッパケース３２をそれぞれ有して伸縮可能に構成されるとともに前輪ＷＦの両側に配置される一対のフォーク脚３３，３３と、一対のアッパケース３２，３２の上部間を相互に連結するトップブリッジ３４と、該トップブリッジ３４よりも下方で前記両アッパケース３２，３２間を相互に連結するボトムブリッジ３５とを備えており、トップブリッジ３４およびボトムブリッジ３５間に設けられるステアリング軸３６が車体フレームＦのヘッドパイプ１６で回動可能に支承される。
【００２２】
図４を併せて参照して、操向ハンドル２２よりも前方には部品としてのウインドスクリーン３７が配置される。このウインドスクリーン３７の中央下部には、フロントフォーク２１におけるボトムブリッジ３５に設けられたブラケット３８で支持されるヘッドランプ３９を臨ませる開口部４０が設けられる。またウインドスクリーン３７の前面側で前記開口部４０の両側方および上方にはガーニッシュ４１が配置されており、ウインドスクリーン３７の背面側には、前記ガーニッシュ４１との間にウインドスクリーン３７を挟む左右一対の取付け板４２，４２が配置され、ガーニッシュ４１、ウインドスクリーン３７および取付け板４２，４２は共締めされる。
【００２３】

【００２４】
フロントフォーク２１が備える一対のフォーク脚３３，３３において、自動二輪車の前進方向を向いた状態で左側に配置されるフォーク脚３３のアッパケース３２には、上下一対の部品取付け具４５Ｌ，４５Ｌが、一方の部品取付け具４５Ｌをトップブリッジ３４に下方から当接させるとともに他方の部品取り付け具４５Ｌをボトムブリッジ３５に上方から当接させるようにして着脱可能に取付けられ、また自動二輪車の前進方向を向いた状態で右側に配置されるフォーク脚３３のアッパケース３２には、上下一対の部品取付け具４５Ｒ，４５Ｒが、一方の部品取付け具４５Ｒをトップブリッジ３４に下方から当接させるとともに他方の部品取り付け具４５Ｒをボトムブリッジ３５に上方から当接させるようにして着脱可能に取付けられる。
【００２５】
上下で対をなす部品取付け具４５Ｌ，４５Ｌ；４５Ｒ，４５Ｒのうち上方の部品取付け具４５Ｌ，４５Ｒには、ウインドスクリーン３７に設けられている上取付け部４２ａ，４２ａが支持され、また下方の部品取付け具４５Ｌ，４５Ｒには、ウインドスクリーン３７に設けられている下取付け部４２ｂ，４２ｂが支持される。
【００２６】
図５〜図８において、自動二輪車の前進方向を向いた状態で左側に配置されるフォーク脚３３のアッパケース３２に、トップブリッジ３４に下方から当接するようにして着脱可能に取付けられる部品取付け具４５Ｌは、アッパケース３２の外周の一部に当接される形状に形成されるとともにアッパケース３２の周方向に沿う一端には被係合部４６ａが設けられる第１抱持部材４６と、アッパケース３２の軸線と平行な軸線まわりに回動することを可能として第１抱持部材４６の他端部に基端部が連結される操作レバー４７と、該操作レバー４７の回動軸線と平行な軸線まわりの回動を可能として操作レバー４７の中間部に一端部が連結される中間レバー４８と、操作レバー４７の回動軸線と平行な軸線まわりの回動を可能として前記中間レバー４８の他端部に一端部が連結されるとともに第１抱持部材４６の前記被係合部４６ａに係脱可能に係合する係合部４９ａが他端に設けられる第２抱持部材４９とを備える。
【００２７】
被係合部４６ａはアッパケース３２の軸線に直交する平面内で略Ｊ字形となる形状を有して第１抱持部材４６の一端に設けられ、また係合部４９ａは、被係合部４６ａに係脱可能に係合するとともに被係合部４６ａとの係合点を支点として第２抱持部材４９が回動することを可能として、アッパケース３２の軸線に直交する平面内で略Ｊ字形となる形状を有して第２抱持部材４９の他端に設けられる。
【００２８】
第１および第２抱持部材４６，４９は、アッパケース３２を共働して抱持し得るものであり、第１抱持部材４６の内面にはラバー５０が貼着される。また第２抱持部材４９の内面のうちアッパケース３２の外面に接触可能な位置にはラバー５１が貼着される。而して各ラバー５０，５１は、第１および第２抱持部材４６，４９がアッパケース３２の外面に直接接触してアッパケース３２の外面に傷がつくことを防止する働きをする。
【００２９】
第１抱持部材４６の外周には、ワイヤから成るレバー保持部材５２の一端側が溶接により固着されており、このレバー保持部材５２の他端には、前記ワイヤを円弧状に曲げ成形して成る係合部５２ａが一体に形成される。
【００３０】
レバー保持部材５２は、第１抱持部材４６の被係合部４６ａに係合部４９ａを係合させた状態にある第２抱持部材４９を第１抱持部材４６と協働してアッパケース３２を抱持する位置まで操作レバー４７を回動操作したときに該操作レバー４７に前記係合部５２ａを弾発的に係合せしめ、該操作レバー４７の回動位置を保持する働きをするものであり、図６で明示するように、アッパケース３２の軸線に沿う方向での操作レバー４７の中央位置Ｃから上下いずれか一方たとえば上方に距離Ｌだけずれた位置で操作レバー４７に弾発的に係合するようにして、第１抱持部材４６に固着される。
【００３１】
第１保持部材４６の他端側上部には、円筒状の取付けボス５３が固設されており、この取付けボス５３にねじ孔５４が設けられる。
【００３２】
第１抱持部材４６の他端部において前記取付けボス５３の下方にはブラケット５８が設けられており、硬質の合成樹脂から成る操作レバー４７の基端部が、アッパケース３２の軸線と平行な軸線を有する支持ピン５９を介してブラケット５８に回動自在に支承される。
【００３３】
操作レバー４７の先端側表面には、該操作レバー４７を指で操作する際に滑りが生じないようにするための複数の窪み６０，６０…が設けられており、レバー保持部材５２の係合部５２ａを操作レバー４７の先端側に係合する際に、それらの窪み６０，６０…の１つに係合部５２ａを係合させるようにしてもよい。
【００３４】
前記中間レバー４８は、アッパケース３２の軸線と平行に延びて第２抱持部材４９の一端部に回動可能に連結される縦杆部４８ａと、該縦杆部４８ａの両端に一端を直角に連ならせる一対の横杆部４８ｂ，４８ｂと、両横杆部４８ｂ，４８ｂの他端にそれぞれ設けられて操作レバー４７の中間部に回動可能に連結される連結部４８ｃ，４８ｃとを一体に有するようにして、たとえばワイヤを曲げ成形することにより形成されるものであり、アッパケース３２の側方から見た側面視では略Ｕ字状となるように形成される。
【００３５】
第２抱持部材４９の一端には、中間レバー４８の縦杆部４８ａを回動可能に連結すべく該縦杆部４８ａを囲繞する連結筒部４９ｂが、曲げ成形により一体に設けられる。また横杆部４８ｂはアッパケース３２の軸線と同一方向から見たときには外方側に突出した山形となるように屈曲されており、横杆部４８ｂの他端を略Ｃ字状に曲げ成形することで連結部４８ｃが形成される。而して中間レバー４８の両連結部４８ｃ，４８ｃは、前記支持ピン５９と平行な連結ピン６１を介して操作レバー４７の中間部に連結される。
【００３６】
また操作レバー４７には、レバー保持部材５２の係合部５２ａを係合する位置側に該操作レバー４７を回動したときに、前記中間レバー４８の両横杆部４８ｂ４８ｂのうち少なくとも操作レバー４７側の部分を収納する一対の収納溝６２，６２が設けられる。
【００３７】
しかも両横杆部４８ｂ，４８ｂのうち各収納溝６２，６２に対応する部分が各収納溝６２，６２の側面に摩擦接触するように、両横杆部４８ｂ，４８ｂおよび両収納溝６２，６２が形成されている。
【００３８】
このような部品取付け具４５Ｌをアッパケース３２に取付けるにあたっては、アッパケース３２を囲むように第１抱持部材４６、操作レバー４７、中間レバー４８および第２抱持部材４９を配置した状態で第１抱持部材４６の被係合部４６ａに第２抱持部材４９の係合部４９ａを係合し、操作レバー４７を第１抱持部材４６側に回動操作する。そうすると、第２抱持部材４９がその一端側を第１抱持部材４６に近接させるようにして係合部４９ａの被係合部４６ａへの係合点を支点として回動し、第１および第２抱持部材４６，４９でアッパケース３２が抱持されることになり、この抱持状態は操作レバー４７にレバー保持部材５２の係合部５２ａを弾発的に係合することによって維持される。
【００３９】
またアッパケース３２から部品取付け具４５Ｌを取外すときには、図９および図１０で示すように、レバー保持部材５２の弾発係合状態を解除する側に操作レバー４７を回動操作すればよく、そうすれば第１および第２抱持部材４６，４９によるアッパケース３２の抱持状態が緩められ、係合部４９ａの被係合部４９ａへの係合状態を解除することで部品取付け具４５Ｌをアッパケース３２から取外すことができ、操作レバー４７の回動操作によってアッパケース３２への部品取付け具４５Ｌの取付け、取り外しを容易に行なうことができる。
【００４０】
ところで、第２抱持部材４９の一端には、中間レバー４８の縦杆部４８ａを囲繞する連結筒部４９ｂが設けられるのであるが、第１抱持部材４６の一端の被係合部４６ａとの係合を解除するとともに縦杆部４８ａの軸線まわりに所定位置まで回動させた第２抱持部材４９を縦杆部４８ａに沿って所定量だけスライドさせるのに応じて両横杆部４８ｂ，４８ｂの一方たとえば下方側の横杆部４８ｂを嵌合させる切欠き６４が、連結筒部４９ｂの軸方向一端（この実施例では下端）に設けられる。
【００４１】
自動二輪車の前進方向を向いた状態で左側に配置されるフォーク脚３３のアッパケース３２に下方からトップブリッジ３４に当接するようにして取付けられる部品取付け具４５Ｌの取付けボス５３には、ウインドスクリーン３７側の上取付け部４２ａが取付けられる。
【００４２】
図１１において、上取付け部４２ａは取付けボス５３の外端に当接される。また後方に開いた略Ｕ字状である上取付け部４２ａには、前記取付けボス５３のねじ孔５４に螺合されるボルト５５が挿通され、このボルト５５の拡径頭部５５ａおよび上取付け部４２ａの外面間にはワッシャ５６およびリング状の弾性材５７が介装される。而してボルト５５の締付けにより、上取付け部４２ａが取付けボス５３およびボルト５５の拡径頭部５５ａ間に挟持されるのであるが、ウインドスクリーン３７に後方側から衝撃的な荷重が作用したときには、ボルト５５を置き去りにして上取付け部２４ａは前方側に移動可能である。
【００４３】
一方、左側に配置されるフォーク脚３３のアッパケース３２に上方からボトムブリッジ３５に当接するようにして取付けられる部品取付け具４５Ｌの取付けボス５３には、ウインドスクリーン３７側の下取付け部４２ｂが取付けられる。
【００４４】
図１２において、取付け孔４３を有する下取付け部４２ｂは取付けボス５３の外端に当接され、取付け孔４３に挿通されるボルト６５を取付けボス５３のねじ孔５４に螺合して締付けることにより、下取付け部４２ｂが取付けボス５３に締結されることになる。
【００４５】
自動二輪車の前進方向を向いた状態で右側に配置されるフォーク脚３３のアッパケース３２にトップブリッジ３４およびボトムブリッジ３５に当接するようにして取付けられる部品取付け具４５Ｒ，４５Ｒは、自動二輪車の前後方向に延びる中心線を含む鉛直面に関して前記部品取付け具４５Ｌ，４５Ｔと対称に構成されるものであり、部品取付け具４５Ｒ，４５Ｒの構造については詳細に説明するのを省略する。
【００４６】
ところで、トップブリッジ３４およびボトムブリッジ３５間のアッパケース３２，３２において、上、下一対の部品取付け具４５Ｌ，４５Ｌ；４５Ｒ，４５Ｒ間にはウインカ６３，６３が支持されており、それらのウインカ６３，６３は、ウインドスクリーン３７の両側に設けられている凹部３７ａ，３７ａに配置される。
【００４７】
次にこの実施例の作用について説明すると、操向ハンドル２２よりも前方に配置されるウインドスクリーン３７が、部品取付け具４５Ｌ，４５Ｌ，４５Ｒ，４５Ｒで支持され、それらの部品取付け具４５Ｌ，４５Ｌ，４５Ｒ，４５Ｒが、フロントフォーク２１が備える一対のフォーク脚３３，３３のアッパケース３２，３２に着脱可能に取付けられるので、操向ハンドル２２では限られていた配置上の自由度を増大しつつ、ウインドスクリーン３７をフロントフォーク２１に容易に取付けることができる。
【００４８】
またウインドスクリーン３７には、上取付け部４２ａと、上取付け部４２ａよりも下方に配置される下取付け部４２ｂとが設けられ、アッパケース３２を抱持する状態と、その抱持状態を解除する状態とを切換え可能に構成されるとともに前記上取付け部４２ａおよび下取付け部４２ｂをそれぞれ個別に支持して上下で対をなす２組の部品取付け具４５Ｌ，４５Ｌ；４５Ｒ，４５Ｒが、一方の部品取付け具４５Ｌ，４５Ｒをトップブリッジ３４に下方から当接させるとともに他方の部品取付け具４５Ｌ，４５Ｒをボトムブリッジ３５に上方から当接させるようにして、アッパケース３２に取付けられるので、ウインドスクリーン３７を位置決めしつつアッパケース３２に容易に取付けることができる。
【００４９】
すなわちウインドスクリーン３７を介して連結された状態にある上下一対の記部品取付け具４５Ｌ，４５Ｌ；４５Ｒ，４５ＲＧＴＡッパケース３２をその周囲から抱くようにして該アッパケース３２に取付けられたときに、各部品取付け具４５Ｌ，４５Ｌ；４５Ｒ，４５Ｒがアッパケース３２に沿って上下に移動することは阻止されることになり、ウインドスクリーン３７の上下位置を一定に保持しつつアッパケース３２に容易に取付けることができる。
【００５０】
しかも各部品取付け具４５Ｌ，４５Ｒは、アッパケース３２の外周の一部に当接される形状に形成されるとともにアッパケース３２の周方向に沿う一端には被係合部４６ａが設けられる第１抱持部材４６と、アッパケース３２の軸線と平行な軸線まわりに回動することを可能として第１抱持部材４６の他端部に基端部が連結される操作レバー４７と、該操作レバー４７の回動軸線と平行な軸線まわりの回動を可能として操作レバー４７の中間部に一端部が連結される中間レバー４８と、操作レバー４７の回動軸線と平行な軸線まわりの回動を可能として前記中間レバー４８の他端部に一端部が連結されるとともに第１抱持部材４６の前記被係合部４６ａに係脱可能に係合する係合部４９ａが他端に設けられる第２抱持部材４９とを備え、アッパケース３２を抱持した状態で操作レバー４７に弾発的に係合して該操作レバー４７の回動位置を保持するレバー保持部材５２と、ウインドスクリーン３７を取付けるための取付けボス５３とが第１抱持部材４６に設けられている。
【００５１】
このような部品取付け具４５Ｌ，４５Ｒによれば、操作レバー４７の回動操作によってアッパケース３２への取付け、取り外しを容易に行なうことができる。
【００５２】
また中間レバー４８は、第２抱持部材４９の一端部に回動可能に連結される縦杆部４８ａと、縦杆部４８ａの両端に一端を直角に連ならせる一対の横杆部４８ｂ，４８ｂと、両横杆部４８ｂ，４８ｂの他端にそれぞれ設けられて操作レバー４７の中間部に回動可能に連結される連結部４８ｃ，４８ｃとを一体に有して略Ｕ字状に形成されるものであり、操作レバー４７には、該操作レバー４７を前記レバー保持部材５２に係合させる側に回動したときに、両横杆部４８ｂ，４８ｂのうち少なくとも操作レバー４７側の部分を収納する一対の収納溝６２，６２が設けられている。
【００５３】
したがってアッパケース３２への部品取付け具４５Ｌ，４５Ｒの取付け状態で中間レバー４８の一部を操作レバー４７内に収納することになり、アッパケース３２への取付け状態での部品取付け具４５Ｌ，４５Ｒをコンパクト化することができる。
【００５４】
