Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、バックホウ装置を運転座席の前方近くに左右
揺動及び固定操作自在に設け、前記バックホウ装置と前
記運転座席の間に配置した操作部の両横に運転ステップ
を設けたバックホウの運転ステップ構造に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention provides a backhoe device provided near the front of a driver's seat so that it can be horizontally swung and fixed, and is arranged between the backhoe device and the driver's seat. The present invention relates to a backhoe operation step structure in which operation steps are provided on both sides of a part.
従来、第４図に示すように、運転ステップ（８）の前端
縁を、全巾にわたってバックホウ装置（３）の左右揺動
軸芯（P2）よりも後方に配置していた。Conventionally, as shown in FIG. 4, the front end edge of the operation step (8) has been arranged over the entire width behind the left and right swing axis cores (P 2 ) of the backhoe device (3).
しかし、バックホウ装置（３）を運転座席（５）に近付
けて、機体の前後長さを小さくし、狭い場所での作業に
好適なバックホウを形成すると、運転ステップ（８）の
前端縁が運転座席（５）に近付き、体格の良い運転者に
とってはひざの曲がりがきつくなって、運転姿勢が窮屈
になり、一層の改良の余地があった。However, when the backhoe device (3) is brought close to the driver's seat (5) to reduce the front-rear length of the body and form a backhoe suitable for working in a narrow space, the front edge of the driving step (8) is changed to the driver's seat. Approaching (5), a driver with a good physique had a tight knee bend, making the driving posture cramped, and there was room for further improvement.
本考案の目的は、バックホウを運転座席に近付けても運
転ステップに楽な姿勢で足を載せられるようにすると共
に、そのことによってバックホウ装置の左右揺動角が減
少しないようにする点にある。An object of the present invention is to allow the foot to be placed in a comfortable posture in the driving step even when the backhoe is brought close to the driver's seat, and to prevent the left-right swing angle of the backhoe device from being reduced thereby.
本考案の特徴構成は、運転ステップの前端縁をバックホ
ウ装置の左右揺動軸芯よりも前方に配置し、前記運転ス
テップの前端縁のうち少なくとも前記左右揺動軸芯側に
位置する一部分を、平面視において、前記左右揺動軸芯
まわりでのバックホウ装置の扇状の揺動範囲の端縁に沿
った傾斜縁に形成したことにあり、その作用効果は次の
通りである。A characteristic configuration of the present invention is that a front end edge of a driving step is arranged in front of a left and right swing axis core of a backhoe device, and at least a part of the front end edge of the driving step, which is located on the left and right swing axis core side, In plan view, the backhoe device is formed on an inclined edge along the end edge of the fan-shaped swing range of the backhoe device around the left and right swing axes, and the function and effect are as follows.
つまり、運転ステップの前端縁をバックホウ装置の左右
揺動軸芯より前方に配置することによって、バックホウ
装置を運転座席に十分に近付けても、運転ステップの前
端縁と運転座席の距離を十分に長くできて、ひざの曲が
りが過度にきつくならない楽な姿勢で運転できるように
なった。That is, by arranging the front edge of the driving step in front of the left and right swing axis of the backhoe, even if the backhoe is sufficiently close to the driving seat, the distance between the front edge of the driving step and the driving seat is sufficiently long. This made it possible to drive in a comfortable position without excessive knee bending.
また、運転ステップの前端縁のうち少なくともバックホ
ウ装置の左右揺動軸芯側に位置する一部分を前記左右揺
動軸芯まわりでのバックホウ装置の扇状の揺動範囲の端
縁に沿った傾斜縁に形成してあるから、バックホウ装置
の左右揺動角を運転ステップの悪影響が無い状態で十分
に大きくできる。In addition, at least a part of the front end edge of the operation step, which is located on the side of the left and right swing axis of the backhoe device, is an inclined edge along the edge of the fan-shaped swing range of the backhoe device around the left and right swing axis. Since it is formed, the horizontal swing angle of the backhoe device can be made sufficiently large without any adverse effect on the driving step.
その結果、機体前後長さが小さくて狭い場所での掘削作
業に便利であり、バックホウ装置の左右揺動角が大きく
て作業性能に優れ、楽に運転ステップに足を載せられて
運転疲労が少ない、全体として優れた超小型のバックホ
ウを提供できるようになった。As a result, it is convenient for excavation work in a narrow space due to the small front-rear length, the backhoe device has a large horizontal swing angle and excellent workability, and it is easy to put your foot on the driving step and reduce driving fatigue. It is now possible to provide a super-compact backhoe that is excellent as a whole.
