Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in a mechanism for locking a throttle cable end to a brake operation lever attached to a handle of a two-wheeled vehicle.

(Prior Art) Generally, a brake operating lever is swingably attached to the handlebar of a two-wheeled vehicle such as a motorcycle or a bicycle. For example, as shown in FIG. 5, a throttle grip 2 is rotatably fitted to a bar handle 1, and a signal switch mounting case 3 is fitted and fixed inside the handle. A bracket 4 is formed protrudingly from the front surface of the case 3, and a protrusion 5a of a brake operating lever 5 is fitted into a protruding groove (not shown) provided on the bracket 4, and is supported by a shaft 6. The lever 5 is configured to be swingable.
Reference numeral 9 denotes a throttle cable connected to the brake mechanism, which is passed through the hole 8 of the bracket 4 and connected to the brake operating lever 5 via the shaft 7.

When connecting the cable 9 to the brake operating lever 5, a hole (not shown) is usually made on the back side of the lever 5, and the end piece 9a of the cable 9 is fitted through the hole, and the shaft 7 is connected to the lever 5. is rotated approximately 30 degrees to lock the cable 9 and prevent it from coming off.

(Problem to be solved by the invention) However, the above-mentioned cable end piece 9
The locking part a has a different shape on the front side and the back side,
There was a drawback that it caused damage, and there was also a problem that it was difficult to lock the cable 9 easily. Furthermore, lever 5
Since it is made of iron, it does not contribute to reducing the weight of motorcycles,
In addition, the left and right levers each have a dedicated structure, so
There were also production issues.

Regarding the attachment of the throttle cable to the handle, the present applicant has already published a work in U.S. Pat.
Although a relatively simple mounting mechanism was proposed in the publication,
It is necessary to cover the locking part of the cable end with a case to prevent it from coming off, and the entire mechanism cannot be said to be necessarily simple, and it cannot be denied that there are difficulties in installation. The problems remain unresolved.

(Means for Solving the Problems) The present invention has been made to solve the above-mentioned problems. Regarding the locking of the throttle cable to the lever, the lever is made of resin and the operating plane is A blind hole is provided for fitting the end piece into the cable, and a resin spring is integrally installed in the hole to lock the cable.

The present invention will be explained in detail below based on illustrated embodiments.

(Example) FIGS. 1 and 2 are explanatory views showing a cable locking mechanism according to this example, and FIG. 1 is a plan view;
FIG. 2 is a side view cut along the line A--A in FIG. 1.

In the figure, 5 is a lever made of resin, and its end on the bracket side is shown, and 6 is a shaft that swingably supports the protrusion of this lever on the bracket.

A blind hole 10 is provided on the operating plane of the lever 5, and the width of this hole is approximately equal to or slightly smaller than the width of the end piece of the throttle cable. Cable exit direction of hole 10 (Figures 1 and 2)
A cable passage groove 12 is provided on the left side in the figure. In addition, an upright portion 11 is formed integrally with the lever body from the bottom of the hole 10 to constitute a resin spring, and a thick locking portion 11 is formed at the free end of the hole 10.
a is formed. The width of this locking part is the width of the groove 1
It is desirable that the width be equal to the width of 2. As is clear from FIG. 2, the resin spring 11 having such a structure has a locking portion 11a that elastically swings in the cable ejecting direction or the opposite direction about the base that is integrated with the lever body. It is possible to do so.

To lock the throttle cable, as shown in FIG. 3, push the end piece 9a into the hole 1 in the direction of the arrow in the figure, push the resin spring 11 out in the opposite direction to the direction in which the cable comes out, Locking part 1
By passing between 1a and the side wall of the hole 10 in the cable exit direction, it can be held elastically below the locking portion 11a.

Moreover, in order to pull out the end piece 9a locked in the hole 10, it is sufficient to simply pull out the end piece 9a in the opposite direction of the arrow, which is easy.

It goes without saying that the thickness and height of the resin spring 11, the shape of the locking portion 11a, etc. are appropriately designed depending on the locking condition of the end piece 9a.

(Effects of the invention) As detailed above, in this invention, the lever is made of resin, making it possible to reduce the weight.Furthermore, the throttle cable can be locked by integrally installing a resin spring in the blank hole. Since it is installed vertically and is realized by the elasticity of the spring, the locking mechanism is simple and there is no problem in terms of strength, so there is no possibility of damage. It is also possible to share the left and right levers.
