〈産業上の利用分野〉
本考案は刈払機の防振ハンドル取付装置の改良
に関するものである。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement of a vibration-proof handle attachment device for a brush cutter.
〈従来の技術〉

現状における刈払機のハンドル取付装置の構造に
ついて着目してみると、下記のようであつた。<Prior Art> In recent years, the performance of brush cutters has improved, and various devised and improved brush cutters have been proposed and provided. When we pay attention to the current structure of the handle attachment device for a brush cutter, we find that it is as follows.

あつた。 Conventional brush cutter handle mounting devices have a vibration-proof structure in which a rotation stopper is fixed to the main pipe or the handle, and this rotation stopper is clamped with a bracket through a vibration isolator such as rubber. The tightening part of the bolt that fixed the rotation stopper was located inside the bracket that held the rotation stopper.

付ける回り止め具を２分割したものがみられる。 Due to this structure, the only way to change or adjust the position and angle of the bracket or the mounting angle of the handle is to take the inconvenient method of disassembling the bracket and loosening the tightening part of the rotation stopper bolt. Nakatsuta. The structure according to Japanese Utility Model Publication No. 57-46742 was devised to eliminate this inconvenience, namely, a bracket that holds the entire detent, and a vibration isolator interposed between the bracket and the detent. There has been proposed a bracket that is provided with a tool insertion hole for loosening the tightening portion of the rotation stopper, thereby eliminating the need for disassembling the bracket. Further, in Japanese Utility Model Publication No. 55-53128, there is seen a device in which the rotation stopper attached to the handle is divided into two parts for the purpose of preventing the attachment position of the handle from moving in the front-rear direction and rotating in the left-right direction.
〈考案が解決しようとする問題点〉
しかし、上記のような構造のものには、下記の
ような問題点があつたのである。<Problems to be solved by the invention> However, the structure described above had the following problems.
工具挿入孔は比較的小さいものであり、工具
によるボルトを緩めたり締めたりする操作がし
難い。 The tool insertion hole is relatively small, making it difficult to loosen or tighten bolts using a tool.
工具挿入孔に草や木の屑等が詰まり易く、こ
れらが詰まつた場合は工具の操作が大変困難に
なる。 The tool insertion hole is easily clogged with grass, wood chips, etc., and when these things become clogged, it becomes very difficult to operate the tool.
工具挿入孔をブラケツトに設けることによ
り、ブラケツト自体の強度が低下する。 By providing the tool insertion hole in the bracket, the strength of the bracket itself is reduced.

振体との間に回り止め手段がないためハンドル
の回り止めの目的を充分に達成できない。 As seen in the latter Jikko No. 55-53128,
If the rotation stopper is divided into two parts and attached to the handle, even if the tightening bolt is exposed at both ends, it is not easy to assemble because the external vibration isolator is cylindrical, and the rotation stopper is difficult to assemble. Since there is no rotation preventing means between the handle and the vibration isolator, the purpose of preventing the handle from rotating cannot be sufficiently achieved.

の防振ハンドル取付装置を開発した。<Means for Solving the Problem> Therefore, in order to solve the above problem, a rotation stopper 12 which is divided into two parts and provided with rotation prevention ribs 16, 16 on both sides is attached to the handle 11 with tightening bolts 13 at both ends. The outside of the rotation stopper 12 is covered with a vibration isolator 15 which is divided into two parts, leaving the bolt tightening parts at both ends, and the outside thereof is divided into two in the same direction as the rotation stopper 12, and A vibration-proof handle mounting device for a brush cutter has been developed in which the tightening bolt 13 is left in place and is clamped by a handle bracket 14.

The structure is such that a blade 6 is rotated by a shaft 4 installed in a long main pipe (operating rod) 3 from an engine 1 via a clutch case 2, and a gear case 5 connected to the shaft 4. A handle 11 is attached to the main pipe 3 using the handle attachment device 10 of the present invention to facilitate brush cutting work.

るのである。 To explain the handle mounting device 10 of the present invention with reference to FIGS. 1 to 3, the handle mounting device 10 is similar to the conventional product.
A rotation stopper 12, which is divided into upper and lower halves and has anti-rotation ribs 16 on both sides, is tightened so as to hold the handle 11 with a tightening bolt 13, and the rotation stopper 12 is divided into two parts. Vibration isolator 1
It is held between handle brackets 14 via 5. Here, the feature of the present invention is that the tightening bolt 13 of the rotation stopper 12 is exposed to the outside of the handle bracket 14, which makes it possible to disassemble and connect the bracket, which was conventionally done. The tightening bolt 13 of the rotation stopper 12 exposed in the present invention can be operated with a tool with the same ease as the operation of the exposed bolt during the operation. By simply operating the tightening bolt 13, the clamping force of the handle 11 can be adjusted using the rotation stopper 12.

様に良好なハンドル取付状態になるのである。 When the clamping force of the rotation stopper 12 on the handle 11 is loosened, the handle 11 is elastically held by the vibration isolator 15 as shown in FIG.
Even without disassembling the handle bracket 14 or loosening the tightening force, the vibration isolator 15 allows the rotation stopper 12 to loosen slightly, and the handle mounting device 10 can rotate or move relative to the handle 11. Then, after adjusting the handle to a predetermined angle or position, when the tightening bolt 13 is tightened back, the handle is attached in the same good condition as before the adjustment.

いても同様である。 The handle attachment device 10 described above with reference to the drawings is configured by attaching a rotation stopper 12 to the handle 11 with a tightening bolt 13, and tightening the rotation stopper 12 with a bolt through a vibration isolator 15. However, it is naturally possible to create a handle mounting device with a structure in which the rotation stopper 12 is attached to the main pipe 3 and the rotation stopper 12 is held between the handle bracket 14 via the vibration isolator 15, and the function is also the same. be.

る。<Effects of the invention> As detailed above, with the invention, the tightening bolt of the rotation stopper is exposed on the outside of the handle bracket, so there is no need to disassemble or assemble the handle bracket. The angle of the handle and the position and angle of the bracket can be changed simply by operating the tightening bolt. In addition, by making it easier to adjust the position and angle of the handle, even inexperienced workers can adjust the position and angle of the handle to a position that makes it easier for them to perform their desired work, and the handle remains stable without turning. This makes mowing work easier and improves work efficiency. In addition, it is easier to operate the tool than a structure with a tool insertion hole in the handle bracket, etc., and the tool insertion hole will not be clogged with grass or wood debris, which will deteriorate the operability of the tool. Another advantageous feature of the present invention is that it does not reduce the strength of the handle bracket. In addition, there is a risk that the bolts may come loose due to engine vibrations during grass cutting, but in preparation for this, you can always directly check the tightness of the bolts, and if you find that the bolts are loose, disassemble the bracket. Since the bolt can be easily tightened immediately with a tightening tool, there is no need to continue work in a dangerous condition with the bolt loosened, and this greatly contributes to safety measures in brush cutting work.
