Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shoulder hanging device for carrying a portable working machine such as a brush cutter on the shoulder of a worker, and a portable working machine capable of suppressing movement of the portable working machine when the portable working machine is temporarily lowered to the ground. The present invention relates to a shoulder bag device.

[0002]

[Prior art]

 In mowing work, an operator may temporarily suspend the work by lowering the brush cutter to the ground without stopping the engine. In that case, if the vibration of the engine is directly transmitted to the ground, the brush cutter will move in a turbulent manner due to the reaction force, and the lower part of the engine power unit will be worn down. For this reason, in the prior art, a stand is attached to the engine power unit and the engine power unit is supported on the ground via the stand, or legs of elastic members are attached to the lower surface of the engine power unit, and the legs are attached via the legs. The engine power section is supported on the ground.

[0003]

[Problems to be solved by the device]

 Support by stands and elastic legs is not sufficient to stop the movement of portable work equipment.

An object of the inventions of claims 1 and 2 is to provide a shoulder rest device for a portable working machine that can effectively suppress movement of the portable working machine while omitting addition of a special member.

[0005]

[Means for Solving the Problems]

 The invention will be described using the reference numerals of the drawings corresponding to the embodiments. A shoulder hanging device (22) for a portable working machine, which is the premise of claim 1, is a shoulder strap (23) mounted so as to suspend the portable working machine (10) and hung on the shoulder of a worker (20); The work machine (10) has a plate-like protection member (24) attached to the shoulder strap (23) so that the work machine (10) is in a position to contact the body of the worker (20). Further, in the shoulder device (22) for a portable working machine according to claim 1, the plate-shaped protection member (24) receives the engine power unit (14) of the portable working machine (10) from the upper side at the time of grounding. 26)

In the shoulder device (22) for a portable working machine according to claim 2, the receiving portion (26) is a recess (26) into which the lower end portion of the engine power portion (14) fits.

[0007]

[Action]

 In the shoulder device (22) for a portable working machine according to claim 1, during work, the plate-like protection member (24) is attached to the shoulder strap (23), and the worker (20) and the portable working machine (10) are attached. The vibration is prevented from being transmitted from the portable work machine (10) to the worker (20) by being interposed between the work machine and the worker. When the worker (20) temporarily suspends work without stopping the engine (30), the portable work implement (10) unlocked from the shoulder strap (23) is placed on the ground. It is received by the receiving portion (26) of the laid plate-shaped protection member (24). The plate-like protection member (24) has a sufficient ground contact area, holds friction with the ground, and supports the engine power section (14) without causing movement due to vibration.

In the shoulder device (22) for a portable working machine according to claim 2, the engine power section (14) of the portable working machine (10) has a plate-shaped protective member (24) at its lower end portion during the temporary interruption of the work. It is fitted into the recess (26) and is received by the plate-like protection member (24), and is supported while maintaining its posture.

【Example】

 The present invention will be described below with reference to the embodiments shown in the drawings. FIG. 3 is a diagram showing a situation where the worker 20 is carrying the brush cutter 10 and is working. The brush cutter 10 has a long operating tubular operating rod 12, an engine power unit 14 attached to the rear end of the operating rod 12, and a cutting blade 16 attached to the front end side of the operating rod 12. . The cutting blade 16 is rotated by the rotational power transmitted from the engine 30 (FIG. 1) of the engine power unit 14 via a transmission shaft (not shown) in the operating rod 12. The safety cover 18 almost covers the rear half of the cutting blade 16 and prevents stones or the like that are hit by the cutting blade 16 and thrown away from the operator 20. The shoulder hanging device 22 includes a shoulder hanging band 23 that can be hung on the shoulder of the worker 20, and a plate-like protective member 24 (FIGS. 1 and 2) described below. It is removably hung on the lower end of 23 and hung on a shoulder strap 23.

Although not shown in FIG. 3, the plate-like protection member 24 (FIGS. 1 and 2) is attached to the lower end portion of the shoulder strap 23 so as to be in a position where it strikes the waist of the worker 20 on the side of the brush cutter 10. It is detachably attached to prevent the engine power unit 14 from directly touching the body of the worker 20, and protects the worker 20 from heat, vibration, friction, and collision of the engine power unit 14.

FIG. 1 is a cross-sectional view of the plate-shaped protective member 24 laid on the ground and receiving the engine power unit 14, and FIG. 2 is a perspective view of the plate-shaped protective member 24. The engine power unit 14 has an engine 30 and a fuel tank 32 arranged below the engine 30. The plate-shaped protective member 24 has a rectangular recess 26, which is shaped to fit with the lower portion of the fuel tank 32 at the lower end of the engine power unit 14, on one side. The mounting bracket 28 is provided on the side portion of the plate-shaped protection member 24 and is detachably attached to the lower end portion of the shoulder strap 23 (FIG. 3).

The operation of the embodiment will be described. During the mowing work, the brush cutter 10 is carried by the worker 20 through the shoulder device 22 (FIG. 3). The plate-shaped protection member 24 is located at the lower end of the shoulder strap 23 and is interposed between the brush cutter 10 and the worker 20, and the engine power unit 14 impinges, rubs, or heats the engine 20 on the worker 20 during work. , And protect the worker 20 from vibration.

When the mowing operation is temporarily stopped without stopping the engine 30, the worker 20 unlocks the shoulder mounting device 22 and lowers the brush cutter 10 and the plate-like protection member 24. At this time, the plate-shaped protection member 24 is laid on the ground as shown in FIG. 1, and the engine power unit 14 inserts the lower end of the fuel tank 32 into the rectangular recess 26 of the plate-shaped protection member 24. Then, the plate-shaped protection member 24 is supported while maintaining its posture. The plate-shaped protection member 24 has a sufficient area, which ensures a large friction with the ground, and the plate-shaped protection member 24 violates and moves on the ground regardless of the vibration of the engine 30. Is suppressed.

[0014]

[Effect of device]

 According to the first aspect of the present invention, the engine power unit of the portable working machine can be placed on the ground through the plate-shaped protection member already provided on the shoulder device, and the plate-shaped protection member is sufficient. Since it has an area and has sufficient frictional force with the ground, it prevents the movement of the mobile work machine when the mobile work machine is lowered to the ground while omitting the addition of special members. it can.

According to the second aspect of the present invention, the recess can effectively receive the engine power unit of the portable work machine to maintain the posture.
