Description

[Detailed Description of the Invention] (Industrial Application Field) A prime mover is attached to the proximal end of the operating tube, a saw blade is attached to the tip via a gear housing, and a saw blade is attached to the tip of the operating tube via a drive shaft inserted into the operating tube. In a lawn mower that rotates a lever blade, operating cables such as the motor operating cable and switch lead wires are usually extended to the grip attached to the operating tube or the grip of the handle attached to the operating tube. .

The present invention relates to improvements in means for extending operating wires such as cables and lead wires. / (Prior art and problems) A pipe with a circular cross section is used for the operating tube of a lawn mower or a handle attached to the operating tube, and a circular grip made of rubber, synthetic resin, etc. is used as a gripping portion of the operating tube or handle. installed.

In order to drive the mower by operating a lever provided on the grip, conventional methods are used to extend operating cables such as the motor operating cable and switch lead wires to the grip. There is.

That is, as shown in the cross-sectional view of FIG.
was provided, and an operating wire was inserted into the circular through hole 23.

Therefore, the grip 22 has a through hole 2 of the operating tube 21.
4 and the operating line through hole 23, and in order to make it as thin as possible and easy to grip, the outer shape was approximately oval as shown in the figure.

Also, a potbellied shape as shown in the cross-sectional view of FIG. 8 was also observed.

Therefore, since the outer shape of the grip 22 is not circular, it is difficult to grip, and the operation line is exposed outside the grip 22 and can be hooked by hand, making it inconvenient to use and having an unfavorable appearance.

In addition, although the above example described the grip attached to the operation tube, the same applies to the grip of the handle.

(Means for Solving the Problems) The present invention solves the above-mentioned drawbacks, and its means include attaching a prime mover to the proximal end of the operation tube, a saw blade to the distal end via a gear housing, In a lawn mower, the saw blade is rotated from the prime mover through a drive shaft inserted into the operating tube.
At least one recess into which the motor operating cable, switch lead wire, etc. can be inserted is formed on a part or the entire length of the outer wall of the operating tube or on the outer wall of the handle attached to the operating tube.

(Example) Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a perspective view of the mower, in which 1 is an operating tube having a grip 2, 3 is a prime mover fixed to the base end of the operating tube 1,
4 is a gear housing fixed to the tip of the operating tube 1;
Reference numeral 5 denotes a saw blade that rotates via a drive shaft inserted through the operating tube 1.

As shown in the sectional view of FIG. 2, a substantially V-shaped recess 7 facing the axis is formed in a part or the entire length of the outer wall of the operation tube 1, and a recess 7 for operating the prime mover is formed in this recess 7. An operating wire 8 such as a cable or switch lead wire is inserted.

Note that 6 is a drive shaft, 9 is a vibration-proof rubber, and 10 is an oil-less metal.

Figures 3 to 6 show modified examples of the recess 7. Figure 3 shows one in which the opening is formed into a narrow circular shape, Figure 4 shows one in which it is formed in a U-shape, and Figure 5 shows one in which the opening is formed in a U-shape. In the example shown in FIG. 6, two U-shaped recesses are formed symmetrically, and in FIG. 6, four U-shaped recesses are formed at equal intervals.

Although the above embodiment has been described with respect to the operating tube, when a handle is attached to the operating tube, the operating tube and the handle are provided with an operating line insertion recess similar to the above.

(Effects) As described above, in the present invention, operating wires such as a prime mover operating cable and a switch lead wire are inserted into a part or the entire length of the outer wall of the operating tube or into a recess provided in the outer wall of the handle. The grip attached to the tube or handle can have a circular outer shape and a uniform thickness, making it easy to hold and stably holding and operating the mower.

Furthermore, since the operating wires are not exposed to the outside, it is easy to use and does not spoil the appearance.

Claims (1)

[Claims] In a grass mower, a prime mover is attached to the base end of the operating tube, a saw blade is attached to the tip via a gear housing, and the saw blade is rotated from the prime mover via a drive shaft inserted into the operating tube. A mower, characterized in that at least one recess into which an operating line such as the motor operating cable or a switch lead wire is inserted is formed on a part or the entire length of the outer wall of the handle or on the outer wall of the handle attached to the operating tube.
