Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a maintenance tool for motorcycles, which is used particularly when attaching and detaching a rear wheel.

[Prior art]

Generally, a muffler in a motorcycle is disposed on the side of the rear wheel, and is disposed at a position above a certain height from the standpoint of functionality such as ground resistance and design.

However, the rear wheel is located in the most suitable position for installing the muffler, and therefore, the presence of the muffler reduces the efficiency of maintenance, inspection, and replacement of rear wheel-related parts. .

For this reason, in the past, a concave portion was provided at the part of the muffler corresponding to the axle to ensure space for maintenance work, or the muffler was constructed to be removed for maintenance.

[Problem that the invention attempts to solve]

However, the former structure requires a complicated muffler structure and is not favorable in terms of silencing performance, while the latter structure has the disadvantage of decreasing workability.

Furthermore, in the case of motorcycles, it is considered desirable to be able to easily carry out maintenance work of this kind, especially when on the go, such as in the event of a flat tire while driving.

[Means for solving problems]

The present invention was developed in view of these circumstances, and is a maintenance tool for use in this type of motorcycle in which the muffler is located on the side of the axle of the rear wheel. , and connecting portions arranged at both ends of the tool main body, which are connected to the pivoting end of the rear arm and the seat rail respectively via these connecting portions, and at least one of these connecting portions is connected to and disconnected from the rotating end of the rear arm. The problem of these connecting parts is fixed by using a possible latching device, and the distance between the seat rail and the rear arm is set to be equal to the distance between the seat rail and the rear arm when the rear cushion is compressed and the wheel is positioned above the muffler. .

[Effect]

Therefore, the present invention provides a maintenance tool for a motorcycle that has a simple structure and can be carried while the motorcycle is running, and that improves the workability of maintenance on the rear wheel by separating the rear wheel and the muffler. be.

〔Example〕

Hereinafter, the configuration will be explained in detail with reference to embodiments shown in the drawings.

FIG. 1 shows a maintenance tool according to the present invention installed on a motorcycle, and FIG. 2 is a sectional view of the maintenance tool.

In these figures, reference numeral 1 indicates a maintenance tool according to the present invention, which is composed of a tool main body 1a made of an elongated metal rod, and a hook 1C provided with a pivot 1b at both ends of the tool main body 1a ( The hook in this embodiment also corresponds to the connection part in the present invention).

Reference numeral 2 denotes a seat rail constituting an upper member of the frame of a motorcycle, 3 a mounting piece welded to this seat rail 2, 4 a rear wheel, and 5 a rear arm that supports this rear wheel 4 with a wheel 6, which is attached to the frame. It is well known that Japan is supported by the United States.

Reference numeral 7 denotes a rear cushion interposed between the seat rail 2 and the rear arm 5, which cushions vibrations or impacts of the rear wheel 4.

The attachment piece 3 and the rear arm 5, which are integral with the seat rail 2, are each provided with an engagement hole 8 into which the latching member 1c engages, so that they can be engaged and detached.

Therefore, when it is necessary to remove the rear wheel 6, such as when replacing a tire, the stand is removed, the wheel is placed on the ground, and the rear cushion 7 is compressed by the weight of the vehicle, and if necessary, the seat rail 2 (actually the rear cushion 7) by pressing the seat 9) from above.
is sufficiently compressed, and in this state, both latches IC of the maintenance tool 1 are held by engaging them in the engagement holes 8 of the seat rail 2 and the rear arm 5, respectively.

That is, the rotating end of the rear arm 5 is connected to the maintenance tool 1 while being moved upward.

From this state, the stand is hung to lift the rear wheels and perform the desired work.

In the embodiment shown in the figure, the tool main body 1a is formed of a rod and has two similarly configured rotatable hooks 1c at both ends. In consideration of this, the rod portion may be formed of a flexible material such as an elongated chain or wire.

Furthermore, the hook 1c does not necessarily need to be provided at both ends, but may be provided only at one end, and the other end may be rotatably fixed to the seat rail or rear arm (even when such a configuration is adopted, the present invention (corresponds to the connecting part).

With such a structure, it goes without saying that a holder for holding the other end of the tool body 1a must be provided on a part of the frame or on the rear arm.

In this way, since the maintenance tool 1 has a simple configuration,
It is also possible to carry this maintenance tool 1 while driving the motorcycle.

[Effect of idea]

As explained above, the maintenance tool of the present invention has 1. This type of maintenance tool is used for motorcycles with a muffler located on the side of the axle of the rear wheel, and has a main body made of an elongated body and connecting parts arranged at both ends of the main body. The pivoting end of the rear arm and the seat rail are respectively connected through these connecting parts, and at least one of these connecting parts is provided with a removable latch, so that these connecting parts are connected to each other. The distance is set equal to the distance between the seat rail and the rear arm when the rear cushion is compressed and the axle is positioned above the muffler.

Therefore, it is possible to connect the seat rail and the rear arm with the extremely simple operation of compressing the rear cushion and locking the locking device, and it is possible to maintain the distance between the muffler and the rear wheel by separating the muffler and the rear wheel. This makes it easy to work around the rear wheels.

As a result, there are fewer restrictions on the mounting position of the muffler, resulting in the effect of increasing the degree of freedom in design.

Furthermore, since the maintenance tool has a simple structure, it is possible to carry this maintenance tool with you when riding a motorcycle.
It is suitable for motorcycles because it can meet the desire to perform maintenance work while driving.
