Description
歩行型芝刈機は小型であるから、高さ調整機構の調整作業をするときの作業者の姿勢は、前屈みになる。しかも、作業者は歩行型芝刈機の脇に立つことになる。例えば、高さ調整グリップがハウジングの左の側部の近傍に設けられているときには、作業者は歩行型芝刈機の左脇に前屈みになって立ち、右手によって高さ調整グリップを握ることになる。このような前屈み姿勢のときに、自然に下ろした手によって高さ調整グリップを楽に握って昇降作業をすることができるように、請求項3の発明では、ハウジングに対して高さ調整グリップを前後方向に細長く且つ前下がりとなるように傾けている。しかも、前下がりの傾斜角を20°から30°の範囲に設定することによって、一層容易に高さ調整グリップを握ることができる。高さ調整グリップを手で握り易いので、高さ調整グリップを握っている手の親指にも力を入れ易い。従って、高さ調整機構の操作性が高まる。
また、バネ45の代わりにガスダンパを採用することが可能である。
また、表示部83を有している円弧部81は、前及び後輪支持部材21L,22Lのいずれか一方に備えていればよい。また、円弧部81は、前及び後輪支持部材21L,22Lのいずれか一方に一体に形成された構成であってもよい。
Claims (2)
- 作業者が歩きながら操縦するための操作ハンドルを有し、ハウジングに収納された刈刃によって芝草を刈りながら動力又は人力によって走行することが可能な歩行型芝刈機であって、
地面に対する前記ハウジング及び前記刈刃の高さを調整するための高さ調整機構と、この高さ調整機構の調整動作を規制状態から許容状態に切替操作する操作釦と、この操作釦が操作されることによって前記高さ調整機構の調整動作が許容されているときに、前記ハウジングを持ち上げて昇降させるように手で握る高さ調整グリップとを有し、
前記高さ調整グリップは、前記ハウジングに対して左右一方の側部の近傍に設けられ、且つ前記操作釦は、前記高さ調整グリップの先部に位置し、指による高さ調節グリップの後方への押圧操作で操作部材をスイング動させて前記高さ調整機構のロック機構を規制状態から許容状態に切り替え、
前記操作釦は、押し操作方向が前記高さ調整グリップの中心線に略平行となるように位置し、
先部に操作釦を有する前記高さ調整グリップは、前記ハウジングに対して、前後方向を向いて前後後方に細長い、
ことを特徴とする歩行型芝刈り機。 - 前記高さ調整グリップは、前下がりとなるように傾斜しており、前下がりの傾斜角は、地面に平行な基準水平線に対して20°から30°の範囲に設定されていることを特徴とする請求項1記載の歩行型芝刈機。
