Conventionally, a shoulder strap (harness) provided with a waist belt and a shoulder belt is known, but the body shape (or body shape) of the worker varies depending on the worker. For example, the height, weight, waist circumference, etc. may differ depending on the person (depending on nationality, gender, etc.). With the conventional harness, the length can be adjusted on the front surface of the shoulder belt or the like, but depending on the body shape, the shoulder pads attached to the shoulder belt may not be adjusted to an appropriate position. It was also possible to adjust the length on the front surface of the waist belt, but depending on the body shape, the waist support placed on the side surface could not be adjusted to an appropriate position. Therefore, when a certain harness is used, it is suitable for a worker having a specific body shape, but there is a problem that it is difficult to obtain a good wearing feeling when the worker changes.

It is an object of the present invention to provide a harness for a portable work machine that can be adapted to workers of all body shapes and has an excellent fit.

The portable work machine harness (1; 1A) according to one aspect of the present invention is hung on the left and right shoulders of the worker (A), respectively, and the left shoulder pad (13) and the right shoulder pad (13) are hung in the middle portion in the length direction. The front end and the rear end of the left shoulder belt portion (10; 10A) and the right shoulder belt portion (20; 20A) and the left shoulder belt portion (10; 10A) and the right shoulder belt portion (20; 20A) having 23), respectively. An annular waist belt portion (30; 30A) connected to the operator (A) to cover the circumference of the waist, and between the left shoulder pad (13) and the right shoulder pad (23) and the front end. , Left shoulder belt portion (10; 10A) and right shoulder belt portion (20; 20A) are provided with front shoulder adjustment portions (16, 26) for adjusting the length, and left shoulder pad (13) and right shoulder pad (13). Between 23) and the rear end, there is a shoulder rear adjustment portion (17, 27; 75) for adjusting the length of the left shoulder belt portion (10; 10A) and the right shoulder belt portion (20; 20A). Provided, on the front and rear surfaces of the waist belt portion (30; 30A), a waist front adjustment portion (40) and a waist rear adjustment portion (44; 76) for adjusting the length of the waist belt portion (30; 30A) are provided. , 77) are provided respectively.

According to this portable work machine harness (1; 1A), the front shoulder adjustment portion (16, 26) and the rear shoulder adjustment portion (17, 27; 75) are provided by the left shoulder belt portion (10; 10A) and the right shoulder. The length of the belt portion (20; 20A) can be adjusted. The operator (A) arranges the left shoulder pad (13) and the right shoulder pad (23) at appropriate positions on the left and right shoulders, respectively, and on both the front and rear sides, the front shoulder adjustment unit (16, 26). And the length of the left shoulder belt portion (10; 10A) and the right shoulder belt portion (20; 20A) can be adjusted by the shoulder rear adjustment portion (17, 27; 75). The adjustment before and after the left shoulder pad (13) and the right shoulder pad (23) also has the effect of reducing the bias of the load on the shoulder of the operator (A). Further, the length of the waist belt portion (30; 30A) can be adjusted by the waist front adjustment portion (40) and the waist rear adjustment portion (44; 76,77) on both the front side and the rear side. As a result, the left side surface and the right side surface of the waist belt portion (30; 30A) are arranged at appropriate positions on the left and right without being biased back and forth. With the above configuration and operation, the harness for the portable work machine (1; 1A) can be fitted to the worker (A) of any body shape, and the wearing feeling is excellent.

In the above-mentioned harness for portable work machine (1; 1A), on the left side surface or the right side surface of the waist belt portion (30; 30A), a holding portion (5) for holding the main body of the portable work machine or an instrument related to the portable work machine. 80) may be attached. As described above, the front waist adjustment section (40) and the rear waist adjustment section (44; 76,77) arrange the left and right surfaces of the waist belt section (30; 30A) at appropriate positions on the left and right sides. Therefore, the holding portion (5; 80) is also arranged at an appropriate position on the left and right. Therefore, the worker (A) can easily hold the main body of the portable work machine by hand and handle the equipment related to the portable work machine by hand.

According to the harness for a portable work machine (1; 1A) of the present invention, it can be fitted to a worker of any body shape and has an excellent wearing feeling.
