JPS591461Y2 - Anti-vibration and safety device for shoulder straps for brush cutters - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to an anti-vibration and safety device for a shoulder band for a brush cutter.

To prevent the transmission of vibrations from the brush cutter to the shoulder of the human body, a shock absorber (note) is provided between the band and the hook ring.
This buffer is suspended by a band.

), in order to prevent the danger of the brush cutter coming off the shoulder if the shock absorber made of rubber or the like breaks, the conventional brush cutter should be placed in the appropriate position as shown in the reference diagram. The bush cutter is supported by being lifted by a band 29 via a cushion ring 25 formed in a ring shape from a suitable elastic material, and the bush cutter and the band 29 are connected by a safety fitting 21 made of a stronger member than the cushion ring 25. are installed separately (note, the installation involves the ring indicated by the symbol 21, the hook 23, the triangular ring 17, the mounting bracket 19, and the mounting pipe 1.
This is done through 5.

) has been proposed (note, Japanese Utility Model Publication No. 50-18890).

However, in the case described in this publication, the code 21
Attach the cushion ring 25 and safety fitting 2 to the ring shown in
It is necessary to connect the members 7, which requires a lot of effort to assemble, and this is combined with the fact that apart from the ring 21, the cushion ring 25 made of rubber or the like and the safety fitting 27 are made of different materials. Therefore, it is inevitable that costs will increase.

Furthermore, in the device described in this publication, there is a risk that the band 29 may come into contact with the safety fitting 27 that prevents vibration transmission, and therefore, it is difficult to completely prevent vibration transmission.

This invention was developed by focusing on the points mentioned above, and its purpose is to prevent vibration transmission and obtain safety with an extremely simple structure, and to provide a shoulder strap for a brush cutter that can be made at low cost and serve as a vibration-proofing device. To provide safety equipment.

Next, an embodiment of the present invention capable of achieving the above object will be described in detail with reference to the accompanying drawings.

1 is a shoulder belt, 2 is a hook, and 3 is a connecting ring.

The buffer body a is made of rubber, and in this embodiment, it consists of a front plate part a1 and a back plate part a2, which are connected only at the lower part, and the lower part between the front plate part a1 and the back plate part 32. A gap g is formed in , and the upper part of the connecting ring 3 is fitted into this gap g.

That is, in this embodiment, the front plate part a1 and the back plate part a2
The connecting ring 3 can be easily inserted into the gap g from the upper part of the connecting ring 3 (note: by pulling down the connecting ring 3 through the space between the front plate part a1 and the back plate part a2).

Furthermore, although this embodiment has a reinforcing rod 4 inserted at the bottom, this is not always necessary.

A plurality of band insertion grooves 5 are vertically provided in the front plate part a1 and the back plate part a2, and the lower part of the band 1 is inserted into the band insertion groove 5 at the lowest stage.

The hook 2 is also connected to a connecting ring 3.

In the configuration described above, the hook 2 is used to hold the brush cutter via a suitable connecting metal fitting, and the band 1 is wrapped around the eyebrows, but vibrations from the brush cutter to the connecting ring 3 can be avoided. is absorbed by the buffer a and is prevented from being transmitted to the belt 1.

In addition, if the upper part of the lowest band insertion groove 5 into which the band 1 is inserted breaks, the band 1 will be caught in the upper band insertion groove 5, and therefore the band 1 will not be detached from the buffer body a. is to be prevented.

Although one embodiment of the present invention has been described above, the present invention is not limited thereto; for example, the buffer body a may not be formed of the front plate portion a1 and the back plate portion a2, but may be formed in a simple single plate shape.

Accordingly, the present invention is constructed by providing a plurality of band insertion grooves in the vertical direction on a buffer body with the upper part of the connecting ring connected to the lower part, and inserting the band into the band insertion groove at the lowest stage. It is possible to achieve the desired purpose well.
