Description

[Detailed Description of the Invention] The present invention is applicable to a brush cutter for mowing grass, a polisher for polishing floors, etc. by holding the handle provided on the body of the machine. This relates to tools that move the floor surface.

For example, a conventional mowing machine has a main body with two rotating blades attached to it, and the work is carried out by holding the handle attached to this main body and shaking it from side to side, but the power source such as the engine that rotates the nine rotating blades is the nine main body. In order to make the hand-held tools lighter, separate e
Generally, the operator carries the engine on his or her back, which has the disadvantage that the vibrations of the engine are directly applied to the operator.Also, in the case where the power source is mounted on the main unit, the main unit is heavy and the However, it is difficult to work in narrow spaces because it requires large wheels to make it easier to move, and it is difficult to work in narrow spaces because it has wheels on the outside of the rotating blade.1 For this reason, the applicant tThe bottom surface of the main body (・This rotation axis
Attach a rotating bowl-shaped lever and operate the handle P.
Therefore, by tilting the legs, the outer circumferential surface of the two-legged body that is off the center comes into contact with the ground, and the frictional force 1 exerts an emotional force on the opposite side of the rotation direction to the main body P, making the movement operation easier. I suggested something.

This type of structure can be applied not only to brush cutters but also to polishers, etc., and is effective for hand-held tools with heavy body weight by placing the power source on the chassis (3). In areas where the running surface that comes into contact with the body is extremely uneven, where there are many stones, or on floors that are slippery and have little friction, it is important to find appropriate friction between the two legs. 1) Your movements may be hindered.

The present invention improves the biped body so that it can act effectively in such cases, and this will be explained in detail with reference to an embodiment shown in FIG.

/ is writing ability I1. A power source such as an engine 3 is mounted on the chassis 2, and its rotating shaft is provided directly or through a bending device W'l to protrude from the bottom surface of the chassis. A leg made of steel plate or synthetic resin is fixed to the lower end of the shaft. B is a rotating blade, 7
1g of holding plate is the handle attached to the chassis, 9 is I+,
The 141 ribs and IO are inclined surfaces.

1υil (+1!;) has a hand-shaped lower surface, and when the main body is turned over from the handle, the contact part with the running surface deviates from the center position of the 1υil body.For this reason, the leg As the body rotates, friction e occurs at the contact part with the running surface.
JP-A-58-40010 (2) The two main bodies are moved in a direction opposite to the direction of rotation due to the reaction force. Therefore, if there are a lot of pebbles on the running surface of the contact area, or if the pebbles are blown away by the counter-wheel, or if the soil is too soft or slippery, there will be no reaction force on the main body/e, and the hand force will be applied via the handles of the two main bodies. It must be moved by one minute.

For this reason, 1 the present invention provides a plurality of ribs in the downward direction of the 11141 body S (a) in the direction of rotation of the 9-legged body S, and a width greater than the height of the rib on the rear side (1). (In slope 10
It is equipped with Therefore, the friction between the legs and the running surface can be increased by the protrusion V of the lipta, and since the inclined surface 10 is facing away from the running direction of the main body, even if there is a stone, it will not be thrown away. The main body can ride on the body and move smoothly without being blown away.

Incidentally, three tilters may be provided on both sides, and if the rotation direction of the lever 41 body is constant, the lipor can be placed one on the rear side of the rotation direction.
・By bending it so that it sticks out, the nine-legged body 5 can be moved easily.

In this way, according to the present invention, the bumps (,5) on the lower surface of the 11141 body are provided to increase the 1ψ friction with the running surface, making it possible to run reliably and without throwing away pebbles etc., making it safer. You can work smoothly, and the legs are reinforced by the ribs.
11141 body can be made thinner and lighter.

The lower part of the rotating shaft l is lighter and the upper part is heavier, improving stability during rotation, and the two bodies can be held easily, so the handle can be easily manipulated and the workability is good.

[Claims] (11 The chassis of the main body - A rotary blade is attached to the rotating shaft protruding downward, and the lower end of this rotating shaft is provided with a star-like leg body. The main body is tilted from the center of the 1υ41 work. Bring the detached outer circumferential elbow into contact with the running cloth (in the direction opposite to the rotational direction of the leg). A hand-held tool such as a brush cutter, characterized in that the ribs are arranged radially, and the ribs are slanted in the rotational direction of the 1000 body to provide an inclined surface with a width of one foot wider than the height of the rear rib.F2+ +iiJ note. The rib is 11t behind the rotational direction of the leg.
