Description

[Detailed description of the invention] "Industrial application field" This invention is a backpack-type engine that has an operating device that can be moved in and out of the machine and that can be tilted. The present invention relates to a mounting device for an operating device in a drive-type work machine.

``Prior Art'' This type of engine-driven work machine has an operating device in which, for example, a mounting plate of an operating lever is fixed to a pipe frame by means such as welding.
Moreover, the control lever was installed in such a way that it protruded outside the machine. For this reason, during transportation, the operating lever protruding from the aircraft body may hit other equipment, resulting in damage, and during packaging, the operating lever protruding from the aircraft body may increase the volume of the package. This caused inconvenience in transportation.

In order to solve this problem, it is conceivable to remove the control lever from the machine body and transport it in a separated state.
However, after transportation, it is necessary to assemble the operating lever to the aircraft body in order to use it, but when assembling it, it is necessary to connect not only the operating lever but also a cord or wire between the operating lever and the aircraft body. For mere users of work equipment, it is not easy to assemble the control lever to the machine body, and it is very time-consuming and troublesome, and there is a risk of parts being lost, making it less convenient. There was a problem that I was missing.

Furthermore, the user carries the machine on his back while working, and since the control lever is fixed to the body of the machine, depending on the user's body shape, for example, the user may have a wide waist or wide shoulders. In some cases, the operating lever was located on the inside of the user's back, making it difficult to grasp and operate it.

``Problem that the invention aims to solve'' Therefore, in view of the above circumstances, the present invention has been developed to immerse the operating device so that it does not protrude from the aircraft body during transportation, etc., to prevent it from colliding with other equipment, and to prevent it from colliding with other equipment. A mounting device for an operating device in a backpack-type engine-driven work machine that allows the operating device to be moved in and out of the machine body, and even tilted, positioned, and fixed so that it can be easily operated according to the user's body shape. The purpose is to provide

"Means to be Solved by the Invention" In order to achieve the above object, the present invention provides a backpack-type engine-driven working machine, in which a flat part is provided on the frame of the engine-driven working machine, and a plurality of flat parts are provided on the frame of the engine-driven working machine.

In FIG. 1, 1 is a pipe frame of a backpack-type working machine 2 such as an engine-driven blower or a chemical sprayer. Of course, a back strap 4 is provided on the back side of the pipe frame 1 with a back plate 3 interposed therebetween. A stay 5 serving as the above-mentioned flat portion is fixed to the lower portion of one side of the pipe frame 1 by welding. The stay 5 has reinforcing ribs 6 on both upper and lower edges.
Screw holes 7 and 8 are formed with two weld nuts 13 and 15 at appropriate intervals above and below the flat surface. A mounting plate 9 is attached to the stay 5. As shown in FIGS. 1 to 5, the mounting plate 9 is curved into a substantially L-shape. A first arc-shaped elongated hole 10 is formed in the upper part of one side of the mounting plate 9 . The first arcuate long hole 1
A second arcuate long hole 11 is formed below 0. The second arcuate long hole 11 is the same as the first arcuate long hole 1.
A right elongated hole 11a whose diameter is centered at one end of 0, and a first
The left elongated hole portion 1 whose radial center is the other end of the arcuate elongated hole 10
1b, the right elongated hole portion 11a and the left elongated hole portion 1.
1b are formed so as to communicate with each other. A bolt or butterfly bolt 12 is inserted through the first arcuate long hole 10 and the screw hole 7 and fastened with a welding nut 13.
Similarly, a bolt or butterfly bolt 14 is inserted through the bolt hole 8 and fastened with a welding nut 15. On the other side of the stay 5, an engine switch 16 is fixed with a metal fitting 17 as in the conventional case, and a throttle lever 18 of the engine is fixed with a metal fitting 19. It goes without saying that the switch 16 is connected to the main body of the working machine 1 by a cord 20, and the throttle lever 18 is connected to the main body of the working machine 1 by a wire 21. Of course, the operating device is not limited to the engine switch 16 or the engine throttle lever 18.

Note that the first arc-shaped long hole 10 is connected to the second arc-shaped long hole 1.
The radius of curvature is the same as that of the right elongated hole portion 11a and the left elongated hole portion 11b of No.1. Further, in FIGS. 2, 4, and 5, 22 is a reinforcing rib.

If the throttle lever 18 or switch 16 protruding from the main body of the work machine 1 becomes an obstacle during transportation, etc., loosen the wing bolts 12 and 14 and tighten one wing bolt as shown in FIG. After rotating the mounting plate 9 about 12 so that the longitudinal direction of the mounting plate 9 is positioned approximately parallel to one side of the pipe frame 1, attach the mounting plate 9 to the stay 5 using the butterfly bolts 12 and 14. are fastened to fix the mounting plate 9. As a result, the mounting plate 9, ie, the operating devices such as the throttle lever 18, are stored in the work machine 2 in a folded state.
