Description

[Detailed Description of the Invention] [Industrial field of application] The present invention mounts an engine on a frame extending forward from a mission case and provides a handle mount on the upper end of the mission case. A boss provided at the base end of the handle support frame is fitted to a support shaft that is erected on the shaft to allow the steering handle to rotate about the longitudinal axis, and the handle support frame and the boss are covered with a cover. Regarding walking type management machine.

[Conventional technology]

In this type of walk-behind management machine, the cords laid across the steering handle side and the machine body side were passed through the gap between the handle support frame and the cover and also outside the boss (reference document). Not listed).

[Problems to be solved by the invention]

Therefore, if the steering handle is turned too much about the longitudinal axis, the cords may wind around the boss and cause the cords to be cut.

In addition, if the cord is lengthened in consideration of it, the winding will be less, but the usual extra cords will be entangled or caught on other members, which may cause the cords to be cut or the operation of the control handle to be wrong. Sometimes became.

An object of the present invention is to eliminate the disconnection of cords and the operation error of the steering handle when the steering handle is turned, and to make it possible to easily adjust the required length of the cords.

[Means for solving problems]

In order to achieve the above object, the present invention is characterized in that the support shaft is formed in a tubular shape, and an insertion hole for connecting the lower end of the support shaft inner pipe line to the outside of the front side of the machine is attached to the mission case and the handle. The cords that are formed at the joint with the base and that are laid across the steering handle side and the machine body side are passed through the gap formed between the upper surface and the rear surface of the handle support frame and the cover, and the support shaft inner pipe The point is that the passage and the front side of the fuselage are passed through the opening, and the notch is formed in the upper side of the rear end of the handle support frame, and the cords are inserted in this notch. Is as follows.

[Action]

In other words, even if the steering handle is largely turned, the cords passed through the support shaft inner pipe and the insertion hole are slightly twisted and are not wound around the boss. Also, since the cords that have passed through the gap between the handle support frame and the cover are engaged in the notches formed at the rear end of the handle support frame, the cords will slacken and hang down from the gap or get caught on other members. Things are also avoided.

In addition, since the cords are inserted through the insertion hole in the front opening of the fuselage formed between the upper surface of the mission case and the handle mount, compared to the case where the cords are passed through the side of the handle mount. , It is easy to adjust the required length of cords for devices around the engine in front of the machine.

[Effect of device]

Therefore, once the cords are wound around the boss when the steering handle is turned once, the cords can be twisted once. Then, the damage or cutting of the cords due to the wrapping around the boss or the entanglement of the cords or the operation error of the steering wheel was eliminated.

Further, since the cords are hung down through the notch formed in the handle support frame, the cost can be reduced without using a clamp fitting or the like for preventing the cords from hanging down.

Moreover, it is possible to easily adjust the required length of cords for devices around the engine in front of the machine.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 4, the frame (2) is projected from the mission case (M) having the traveling wheels (1) pivotally supported at the lower end, and the engine (E) is mounted on the frame (2). At the same time, a steering handle (3) is attached to the upper end of the mission case (M) to form an outline of the walk-behind management machine.

To explain the mounting structure of the steering handle (3),
As shown in FIGS. 1 to 3, the mission case (M)
Form an end face on the upper surface of the handle mounting base (4)
The boss (6) at the base end of the steering handle (3) is rotatably fitted on the support shaft (5) provided upright on the handle mount (4). Then, by operating the lock mechanism (7) attached to the boss (6), the control handle (3) is configured to be freely rotatable around the vertical axis (P) and fixed. is there.

The steering handle (3) has a rectangular rod-shaped handle support frame (8) in which the boss (6) is welded, and a handle rod (9) with a horizontal axis.
It is provided so that the swing can be adjusted around (X), and the main clutch lever (10), steering clutch lever (11), starter switch (12), etc. are attached to this handle rod (9). ) And the top of the handle support frame (8) at the bottom of the open cover (13)
Covered with. An engine stop switch (14) is provided on the rear end surface of the cover (13).

A notch concave portion (Ma) is integrally molded at the front of the upper end surface of the mission case (M) at the time of manufacturing, and an insertion hole (1) opened at the front of the fuselage by joining with the handle mount (4).
5) is formed. Further, the support shaft (5) is formed with a support shaft inner pipe line (5a) communicating with the insertion hole (15) so as to vertically penetrate therethrough.

Cords (16) installed over the control handle (3) side and the body side, that is, electric cords (16) connected to the starter switch (12) and the engine stop switch (14)
Passes through the insertion hole (15), the support shaft inner pipe (5a), and a gap (17) formed between the cover (13) and the upper and rear surfaces of the handle support frame (8). Further, a notch (8a) is formed on the upper side of the rear end of the handle support frame (8), and the cords (16) are inserted into the notch (8a) to hold it so that it does not move. There is.

As described above, in the walk-type management machine, even if the steering handle (3) is largely turned, the cords (16) are slightly twisted and do not wind around the boss (12). )
It is easy to handle without worrying about damage or cutting.

To implement the present invention, the wires connected to the clutch lever and the accelerator lever are connected to the support shaft inner pipe (5a) and the insertion hole (1).
You may pass through 5).

Also, the notch (8a) is narrowed to hold the cords (16),
A hook is provided at the entrance of the cutout (8a) so that the cords (1
