【従来技術】
従来公知の特開平２−２３８１０号公報には、機体フレームの上方にステップおよび座席を設け、該ステップおよび座席の周囲をルーフあるいはフロントウインドあるいはリアウインドにより包囲するように形成したキャビンにおいて、前記キャビンは、前側縦骨格フレームあるいは左右上部骨格フレームあるいは後側縦骨格フレームによりキャビンフレームを形成し、該キャビンフレームに前記ルーフ等を螺子、ボルトにより取付た構成について記載されている。
【０００３】
【発明が解決しようとする課題】
前記公知例は、キャビンフレームの各部分は、それぞれ相違する形状により形成されているから、合成樹脂を使用した時、型の費用等が相当に高く、コストが高いという課題がある。
また、キャビンフレームの各部分の形状に工夫はなく、単に従来の鋼材により形成したキャビンフレームの形状に合わせて合成樹脂により形成しているので、ルーフ等をキャビンフレームに取付けるには、螺子やボルトを必要とし、取付が面倒であるという課題もある。
【０００４】
【発明の目的】
コストの低減、螺子やボルトの不要化、組立の容易化。
【０００５】
【課題を解決するための手段】

【００１１】
しかして、キャビン１内のステップ５は上下動自在に設ける。ステップ５には前側操作パネル６を固定し、前側操作パネル６には上下動自在の上下動杆５９を設け、上下動杆５９の上部は上下操作レバー６０を設け、上下動杆５９の下部はガスダンパー６１のロックレバー６２に接続する。６３は機体側と前側操作パネル６との間に設けた案内ガイド、６４はステップ５の周囲に設けた案内体である。また、前記座席８は、ガスダンパー６５により取付けるが、座席８の下部には座席支持フレーム６６を設け、座席支持フレーム６６の後端には案内溝６７を形成し、案内溝６７にエンジンカバー６９側に設けたスライド案内レール７０を係合させる。なお、前記座席８は軸７１に前側回動可能であり、メンテナンスを行う。
【００１２】
次に実施例の作用を述べる。
本発明は前記構成であり、キャビン１は、略四角形状の中央空間部２３と、該中央空間部２３の上方の一方側中央凹部２４と、一方側中央凹部２４の両側の一方側起立部２５と一方側起立部２５の側部の側方に突き出る側方突出部２６との間にそれぞれ形成した一方側角空間部２７と、中央空間部２３の下方に形成した他方側中央凹部２８と、他方側中央凹部２８の両側に形成した他方側起立部２９と側方突出部２６との間にそれぞれ形成した他方側角空間部３０とからなるフレーム部材２２によりキャビンフレーム１５を形成したから、キャビンフレーム１５を構成するフレーム部材２２の各部に嵌合部材３２や取付部材３７を取付けることで、ルーフ３３や側部フレーム３５やドアウインド１３やリアフレーム４２等のあらゆるものをキャビンフレーム１５に取付けられ、キャビン１の製造、組立が容易となり、外部との遮断性および遮音性に優れたキャビン１にでき、エアコン４７も効率よく作動させることが可能になる。
【００１３】
特に、フレーム部材２２を使用して前側縦骨格フレーム１６等からなるキャビンフレーム１５を構成しているから、同一形状なのでコストを低くでき、加工が容易であり、また、合成樹脂を成形したものなので品質精度も高くする。
また、フレーム部材２２は、略四角形状の中央空間部２３と、該中央空間部２３の上方の一方側中央凹部２４と、一方側中央凹部２４の両側の一方側起立部２５と一方側起立部２５の側部の側方に突き出る側方突出部２６との間にそれぞれ形成した一方側角空間部２７と、中央空間部２３の下方に形成した他方側中央凹部２８と、他方側中央凹部２８の両側に形成した他方側起立部２９と側方突出部２６との間にそれぞれ形成した他方側角空間部３０とにより形成しているから、あらゆる向きに使用しても、強度を確保でき、また、フレーム部材２２のあらゆる部分が嵌合部材３２や取付部材３７を取付けるのに合理的に使用でき、キャビン１の設計の自由度を高める。
【００１４】
しかして、前記キャビン１のキャビンフレーム１５に取付けるルーフ３３は、合成樹脂により左右両側に空間部４４を形成し、空間部４４はダクト４５によりキャビン１内に連通し、一方のダクト４５に後側に設けた接続口４６にエアコン４７の送風口４８を接続し、ルーフ３３の上部内側にはレザー等の任意の内張りをした内装材４９を嵌合させ、また、ルーフ３３の前側にはスピーカー等の取付口５１を設けているから、外部との遮断性および遮音性に優れたルーフ３３とし、一体成形で取付口５１やダクト４５を形成するので製造および組立が容易であり、キャビン１の上部を所謂コックピット感覚に形成して商品価値および作業性を高め、また、キャビン１のコスト軽減、軽量化、組立の容易化に貢献する。
しかして、キャビンフレーム１５に取付けるリアフレーム４２は、下部にエアコン４７を収納固定し、中間部の左右側に送風口４８を設けた筒部材５８を設けているから、リアフレーム４２をユニット化し、組立を容易にする。
しかして、キャビン１内のステップ５は、上下操作レバー６０を上方に引くと、ガスダンパー６１のロックレバー６２がガスダンパー６１内のエアー室を連通させてエアーを流してロックを解除し、上下操作レバー６０によりステップ５を上動させる力を補助して、軽くステップ５を上動させ、ステップ５の高さ調節を行って、作業者の操作性を向上させる。反対に、上下操作レバー６０を下方に押すと、ガスダンパー６１のロックレバー６２がロックを解除し、作業者の体重および下方に押す力により取付フレーム３を下動させる。
【００１５】
この場合、機体側と前側操作パネル６との間に案内ガイド６３を、ステップ５の周囲には案内体６４をそれぞれ設けているから、円滑かつ確実に上下する。
また、座席８は、ガスダンパー６５により上下自在に取付け、座席８の下部には後端に案内溝６７を形成した座席支持フレーム６６を設け、案内溝６７にエンジンカバー６９側に設けたスライド案内レール７０を係合させているから、座席８を確実に上下させるだけでなく、エンジンカバー６９および座席８を容易に移動させることができ、メンテナンスを容易に行える。
【００１６】
【効果】
本発明は、機体フレーム２の上方に取付フレーム３を設け、該取付フレーム３には下部フレーム４を取付け、該下部フレーム４は、下部に作業者の立つステップ５を、該ステップ５の前側には前側操作パネル６を夫々設け、ステップ５の左右いずれか一側は解放し他側には側部操作パネル７を設け、前記ステップ５の後側には座席８を取付ける座席取付部９に形成して構成し、前記下部フレーム４にはステップ５および座席８の周囲をルーフ３３あるいは側部フレーム３５あるいはフロントウインド３８あるいはリアウインド４３により包囲するように形成したキャビン１のキャビンフレーム１５を取付け、該キャビンフレーム１５は、少なくとも、左右一対の前側縦骨格フレーム１６と、前側縦骨格フレーム１６に続く左右上部骨格フレーム１７と、左右上部骨格フレーム１７に続く後側縦骨格フレーム１８を有して構成し、前記キャビンフレーム１５は、略四角形状の中央空間部２３と、該中央空間部２３の上方の一方側中央凹部２４と、一方側中央凹部２４の両側の一方側起立部２５と一方側起立部２５の側部の側方に突き出る側方突出部２６との間にそれぞれ形成した一方側角空間部２７と、中央空間部２３の下方に形成した他方側中央凹部２８と、他方側中央凹部２８の両側に形成した他方側起立部２９と側方突出部２６との間にそれぞれ形成した他方側角空間部３０とにより、前記中央空間部２３の断面四角形の四面の全てに一方側起立部２５または側方突出部２６または他方側起立部２９を形成して断面形状が略同一なフレーム部材２２により形成し、該フレーム部材２２の各部に嵌合部材３２や取付部材３７を介して前記ルーフ３３等を取付て構成した作業機の運転部構造としたものであるから、同一形状のフレーム部材２２を使用して前側縦骨格フレーム１６等からなるキャビンフレーム１５を構成しているので、製造コストを低くでき、加工が容易であり、また、同一形状に成形するので品質精度も高くできる。
また、キャビンフレーム１５を構成するフレーム部材２２の各部に嵌合部材３２や取付部材３７を取付けることで、ルーフ３３等のあらゆるものをキャビンフレーム１５に取付けられ、キャビン１の製造、組立が容易となる。特に、ボルト等を使用しないので、組立が容易にでき、また、シール部材４０の取付も容易になって外部との遮断性および遮音性に優れたキャビン１にでき、作業環境を良好にする。
また、フレーム部材２２は、略四角形状の中央空間部２３と、該中央空間部２３の上方の一方側中央凹部２４と、一方側中央凹部２４の両側の一方側起立部２５と一方側起立部２５の側部の側方に突き出る側方突出部２６との間にそれぞれ形成した一方側角空間部２７と、中央空間部２３の下方に形成した他方側中央凹部２８と、他方側中央凹部２８の両側に形成した他方側起立部２９と側方突出部２６との間にそれぞれ形成した他方側角空間部３０とにより、前記中央空間部２３の断面四角形の四面の全てに一方側起立部２５または側方突出部２６または他方側起立部２９を夫々形成しているから、あらゆる向きに使用しても、強度を確保でき、また、フレーム部材２２のあらゆる部分が嵌合部材３２や取付部材３７を取付けるのに合理的に使用でき、キャビン１の設計の自由度を高める。
