Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a management machine provided with a working unit under an engine, a handle behind the engine, and a carrier handle on the handle.
[0002]
[Prior art]
As a management machine, for example, (1) Japanese Utility Model Publication No. 59-186193 “Walking Management Machine” is known.
According to FIG. 2 of the publication, the above-described technique is such that the engine 1 is mounted on the frame 5 (the reference numeral is the same as that described in the publication), and a protector 6 is provided in front of the frame 5 in order to protect the engine 1. The square handle 7 is extended from the rear of the frame 5, and the stay 8 for the hand is attached to the base of the square handle 7.
[0003]
[Problems to be solved by the invention]
However, the walking-type management machine has a structure in which a heavy body portion such as the engine 1 is concentrated in front of the square handle 7. Therefore, when the management machine is lifted by grasping the stay 8 for the rider, the main body part is greatly rotated and is difficult to carry.
Therefore, when carrying the management machine, the raiser stay 8 and the protector 6 are held and lifted with both hands. By lifting the main body part with both hands, the main body part inevitably approaches the body, and if the main body part is covered with earth and sand, clothes will be soiled with earth and sand. If you lift it with one hand, don't worry.
Therefore, a management machine equipped with a carrier handle that is easy to carry and can be lifted with one hand is desired.
[0004]
That is, an object of the present invention is to provide a management machine having a handle with a carrier handle that is easy to carry.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, according to a first aspect of the present invention, in the management machine having a working part under the engine and a handle at the rear of the engine, and a carrier handle on the handle, the center of the grip part of the carrier handle is managed. Position the gripping part so that it is located behind the vertical line passing through the center of gravity of the machine, and the tip of the gripping part is ahead of the vertical line, and the line segment passing through the center of gravity and the center of the gripping part is the vertical line. The gripping part is inclined forwardly by an angle , and the carrier handle is provided with a mounting part for attaching a resistance bar for adjusting the tillage height of the working part below the carrier handle .
[0006]
Position the gripping part so that the center of the gripping part of the carrier handle is located behind the vertical line passing through the center of gravity of the management machine and the tip of the gripping part is located forward of the vertical line. The gripping part was tilted forward upward by the angle formed by the line passing through the center and the vertical line of the management machine. Therefore, when holding the carrier handle and lifting the management machine, the management machine does not rotate greatly, so that it can be easily transported.
Furthermore, since it is not necessary to hold the management machine with both hands, it is possible to avoid worrying about soiling clothes when carrying the management machine.
[0007]
Moreover, the structure of a management machine can be simplified by providing the attachment part which attaches the resistance rod for adjusting the tillage height of a working part to the downward direction of a carrier handle. As a result, it is possible to promote a reduction in the cost of the management machine.
