DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope guide position changing member, and more particularly to a member formed of a linearly extending spring wire.

[0002]

2. Description of the Related Art A recoil type starter, which is generally used frequently as an internal combustion engine starting device, is provided near an internal combustion engine, so that a position where a rope guide and a handle of an engine starting rope are provided is a starter arrangement of the internal combustion engine. Since it is limited to the vicinity of the installation position, the starting operation may be very difficult depending on the position of the internal combustion engine of the work machine. In particular, Japanese Utility Model Publication No. 50-11859,
Japanese Utility Model Application Laid-Open No. 59-19975 and Japanese Utility Model 2-12303
As described in Japanese Patent Application Laid-Open Publication No. H10-260, since the engine starting device is provided on the back of the worker in the backpack type power working machine, a guide pulley, a support body, and the like are provided to adjust the handle position of the starting rope to the back of the worker. Change from the side to the right side, pull the engine start rope in front of the worker with the left hand to start the engine, or place it on the worker's back from the right shoulder with the flexible guide tube and work with the left hand Start the engine by pulling the engine start rope in front of the operator, or by providing a rigid support tube protruding from the outer periphery of the cover of the engine starter and positioning the rope guide beside the worker to start the engine. In addition to the complicated structure and expensive structure to position the rope guide on the side or shoulders of the worker, the rope is rubbed by the position change member and cuts off early. End up There was a problem. Further, the above-mentioned problem has also occurred when a recoil starter of an internal combustion engine mounted on a vehicle for a traveling work machine is used.

[0003]

SUMMARY OF THE INVENTION The present invention provides such a conventional rope guide position changing device, which is complicated and expensive to attach / detach, with a simple and inexpensive member, and has a large degree of freedom in displacement of the rope auxiliary guide. It is an object of the present invention to provide a rope guide position changing member which has a simple structure and which can be easily started by an operator.

[0004]

That is, a rope guide position changing member according to the present invention is configured such that one end of a spring wire is detachably fixed to a rope guide of an internal combustion engine starting rope, and the spring wire is connected to the vicinity of the rope guide. Extending in the pull-out direction of the rope from a predetermined rope guide change position,
The other end of the spring wire is a rope auxiliary guide at the rope guide change position.

[0005]

Accordingly, the rope guide position changing member according to the present invention is not only simple in structure and inexpensive because it is constituted by one bent spring wire, but also supports the rope auxiliary guide with the spring wire. , The position of the rope auxiliary guide has a degree of freedom of 360 degrees, a great degree of freedom is provided in the direction in which the operator pulls out the rope, the internal combustion engine starting operation becomes easy, and the predetermined rope Even if the rope guide change position is shifted from the guide change position, the rope guide is immediately returned to the original rope guide change position by the spring force of the spring wire. Further, even if the operator releases his / her hand from the handle after pulling the rope, the impact of the handle colliding with the rope auxiliary guide due to the return of the rope can be absorbed.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A rope guide position changing member according to the present invention will be described below with reference to an embodiment shown in the drawings. The figure shows an internal combustion engine starting device (recoil starter) 1 for a power sprayer. Although not shown, the power sprayer is mounted on a vehicle, and the internal combustion engine starting device 1 includes an internal combustion engine 4 and a chemical tank (not shown). ), And the operator has to handle the engine at the standard position of the engine starting rope 2 located at the back of the space between the internal combustion engine 1 and the chemical tank. By pulling 3 ', the internal combustion engine 4 is started. In this state, the starting operation is very difficult. Therefore, as shown by a solid line in FIG. 1, the engine start rope 2 is pulled out to a position where it is easy to work, and is supported by the rope guide position changing member 5 via the handle 3. . The rope guide position changing member 5 is formed by appropriately bending and forming a spring wire such as a spring steel wire, and forming one end 5a of the spring wire 5 into a loop to form the starting device 1.
Screws 7 near the rope guide 6 at the standard position
And the rope auxiliary guide 8 is formed with the other end 5b of the spring wire 5 as a rope guide changing position. The rope auxiliary guide 8 can be formed by winding the tip of the spring wire 5 in a loop shape. In this embodiment, the split resin rope guide 8 is inserted and fixed to the other end 5b formed in the loop shape. I have. Then, the intermediate portion of the spring wire 5 is moved from the vicinity of the rope guide 6 to the rope guide changing position 8.
Until the rope 2 is drawn out, it is formed in a straight line substantially parallel to the rope.

[0007] Since the rope guide position changing member 5 is a linear spring wire from the fixed end 5a to the rope auxiliary guide 8, the handle 3 "is bent as shown by a chain line.
Can be changed as appropriate, and even if the rope 2 is pulled out in a slightly different direction, the rope auxiliary guide 8
Freely follow the direction in which the rope 2 is pulled out, so that the rope 2 is less worn or cut. Further, when the hand is released from the handle 3 as it is when the rope is pulled, the impact colliding with the rope auxiliary guide 8 is absorbed by the elastic deformation of the rope guide position changing member 5. The rope guide position changing member 5 may be fixed with an appropriate metal fitting, and its mounting position is not limited to the engine starter 1 but may be directly fixed to another part of the engine 4. As shown in FIG. 2, it is possible to provide an offset portion 5c on the fixed end 5a side to secure an appropriate gap with peripheral members and to increase the degree of freedom of displacement.

[0008]

As is clear from the above description, the present invention
The spring wire is extended from the vicinity of the rope guide to the rope guide change position in the rope pulling-out direction, and the rope auxiliary guide is provided at the rope guide change position. It is possible to provide a rope guide position changing member that has a large degree of freedom of displacement in the position of the auxiliary guide and facilitates the engine start operation by the operator.
