【発明の属する技術分野】
この発明は、電動三輪型車椅子等の電動車の操作装置に関するものである。
【0002】
【従来の技術】
従来、電動車の操作装置としては、出願人の発明に係る特許第2801605号公報に記載された技術や、実開昭61−5295号公報に記載された技術等がある。
特許第2801605号公報に記載の技術は、ループハンドルを用い、該ループハンドル内に操作ボックス等全ての操作部材を収納位置させたものであり、操作性等が勝れている反面、高価であり、又、ループハンドルは前後方向に大きなスペースが必要であり、後方の座席との間隔が狭くなる欠点を有するものである。
又、実開昭61−5295号公報に記載の操作装置は、バーハンドルを利用し、安価でコンパクトに構成されているものの、アクセルレバーがバーハンドル後方に突出している為、乗降時に不意に接触する危険があり、又、グリップの手前側のアクセルレバーを押下する操作は4本の指でグリップを保持し親指でアクセルレバーを操作する必要があり疲れやすく操作性の悪いものであった。
【0003】
【発明が解決しようとする課題】
この発明は、上記の如き従来技術の欠点を解消して、安価に構成できるものでありながら、乗降等の支障となることなく、しかも操作性の良い電動車の操作装置を提供しようとするものである。
【0004】
ハンドルポスト1上部から左右に延設するバーハンドル2,2の中央に操作ボックス3を設け、該操作ボックス3内でバーハンドル2後方側位置にはポテンショメータ4を回転可能の操作軸5を軸架し、該操作軸5の操作ボックス3外への延長部を前方へ屈曲させバーハンドル2の下方を迂回する槓杆6を形成し、更に外方上方に向け屈曲させてグリップ7に沿うアクセルレバー8を構成すると共に、そのアクセルレバー8の外側端部を更に前方へ向け屈曲させ、該アクセルレバー8を操作した際グリップ7の長さ方向内方側にアクセルレバー8を接当させて最大操作位置を規制可能に構成してなる電動車の操作装置の構成とする。
【0005】
ハンドルポスト1上部には、バーハンドル2,2が取着され、該バーハンドル2,2の中央部には操作ボックス3を設けてある。
該操作ボックス3内には、走行速度指令信号を出力するポテンショメータ4を収納してあり、操作軸5の回転により操作される。該操作軸5は、操作ボックス3内で、バーハンドル2,2位置よりも後方に軸架すると共に、該操作軸5の操作ボックス3外への延長部を前方へ屈曲させバーハンドル2の下方を迂回する槓杆6を形成し、更に、外方上方に向け屈曲させてグリップ7に沿うアクセルレバー8に構成してある。
以上の様に本発明にあっては、構成が簡単で安価なバーハンドル構成でありながら、バーハンドル2のグリップ7前方にアクセルレバー8を配設することができ、操縦者はグリップ7と共に前方に位置するアクセルレバー8を自然な握り込み動作で保持でき、バーハンドル2,2を確実に保持した状態でアクセルレバー8による正確な速度調節が行なえると共に、長時間運転にも疲れることがない。
又、ポテンショメータ4の操作軸5をバーハンドル2の後方側の操作ボックス3内に軸架、該操作軸5の操作ボックス3外への延長部を前方へ屈曲させバーハンドル2の下方を迂回する槓杆6を形成し、更に外方上方に向け屈曲させてグリップ7に沿うアクセルレバー8に構成したものであるから、操作装置がバーハンドル2,2近傍で、しかもその下方をも利用して配置されるものであって、突出量を短かく構成でき、操縦者の乗降の際の接当や、他の障害物との接当を極力少なくでき安全である。
又、アクセルレバー8の外側端部を更に前方へ向け屈曲させ、該アクセルレバー8を操作した際グリップ7の長さ方向内方側にアクセルレバー8を接当させて、アクセルレバー8の最大操作位置、即ち電動車の最高速度を規制するストッパーの機能をグリップ7の長さ方向内方側で行なわせるものであり、特別なストッパーを設ける必要がなく構成を簡単にして安価に提供できるとともに、グリップ7の長さ方向内方側を利用するものであり、ハンドル2やアクセルレバー8の製作誤差によるストッパ位置のバラツキを少なくできる。

又、該取付軸29には下方に突出するピン31を設けるとともに、ハンドルポスト1の下部部材36の嵌合溝30中央に前後に形成する縦溝32と嵌合させ、該縦溝32の前後端によって、バーハンドル2の前後回動範囲を略々直立位置と後方の椅子16上面近傍位置との間に規制してある。
又、嵌合溝30,30の中央付近は若干肉取を行い、取付軸29回動時の摩擦抵抗を減少させてある。
ハンドルポスト1の下部部材36の前部両側部には、横方向に挿通孔33を形成する円筒部34,34を、又、該左右の円筒部34,34間には円筒凹部35を形成し、又、上部部材37の対向合せ面には、下部部材36に対応して中央に挿通孔33を有する円筒部34をその両側に円筒凹部35を形成すると共に、該上下部材36,37の合せ面を嵌合させ側方から挿通孔33,33内にピン38を挿通可能に構成してある。
又、上下部材36,37の後方側を突設し、これらを上下方向に貫通する通しボルト39を設けるとともに把手付ナット40で締付けることにより、上部部材36後部を前部のピン38を中心に回動させ、嵌合溝30,30に嵌合するバーハンドル取付軸29を締付固定可能に構成してある。

該左右の取付板42,42の上下略々中間部には、操作軸5を回動自在に保持させてある。
又、左側の取付板42は、前方に延設され、該延設部に電動車の速度指令信号を発生するポテンショメータ4を取着し、その軸に取軸のギヤ44と操作軸5に取着のギヤ45とを噛合させてある。又、操作軸5に取着のピン23と連結杆41の嵌合溝との間にはトルクスプリング46を巻装し、操作軸5を常にニュートラル位置であるストッパー47へ向け弾発してある。ストッパー47は、左側の取付板42前端から右方向に折曲される取付板48に取着されるボルトにて構成され、その接当位置を調節可能に構成してある。61は補強板であり、連結杆41と溶着し、下部ケース43とネジ止めしてある。
操作軸5は、バーハンドル2と略々一直線状に配置される連結杆41から後方に斜設される取付板42,42間に軸架されており、平面視バーハンドル2に対し操作軸5が後方側に位置しており、更にその両端を下部ケース43両側の通孔から操作ボックス3外へ突出させその延長部を前方外方へ屈曲させバーハンドル2の下方を迂回する槓杆6を形成し、更に外方上方へ向け屈曲させてグリップ7に沿うアクセルレバー8に構成してある。従って、操作装置がバーハンドル2,2の近傍でしかもその下方をも利用して配置され、槓杆6やアクセルレバー8の突出量を極力短く構成してあり、操縦者の乗降の際の接当や、他の障害物との接当を極力少なくでき安全である。なお、操作軸5は、操作ボックス3外方位置で槓杆6との間を分割して嵌合着脱自在に構成し、ボルト止めしてある。
又、アクセルレバー8はグリップ7の長さ方向内方側に接当させて、アクセルレバー8の最大操作位置を規制するストッパー機能を有させてあり、特別のストッパーを設ける必要がなく、又、比較的操作ボックス3から近い位置で規制する為、構成部材の製作誤差による回動範囲のバラツキを少なくできる。
更に、該アクセルレバー8は、グリップ7の長さの約内側半分で平行に接当させ、外側半分をグリップ7から離して回動範囲を規制するものであるから、その規制が確実であるとともに、グリップ7外側部をアクセルレバー8と共に握れば、アクセルレバー8が若干弾性力を有し、その操作フィーリングがよい。

The technology described in Japanese Patent No. 2801605 uses a loop handle, and all the operation members such as an operation box are housed in the loop handle. In addition, the loop handle requires a large space in the front-rear direction, and has a drawback that the distance from the rear seat becomes narrow.
In addition, although the operating device described in Japanese Utility Model Publication No. 61-5295 uses a bar handle and is constructed inexpensively and compactly, the accelerator lever protrudes rearward of the bar handle, so it suddenly contacts when getting on and off. In addition, the operation of depressing the accelerator lever on the near side of the grip requires holding the grip with four fingers and operating the accelerator lever with the thumb.
