Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting device that allows a throttle cable consisting of two cables, one on the tension side and one on the return side, to be easily attached to the throttle grip.

The throttle cable that connects the throttle grip and the carburetor is sometimes composed of two cables, one on the tension side and the other on the return side, for the sake of reliability of operation. Conventionally, these two cables were connected to the throttle It was very troublesome to attach it to the grip.

That is, the throttle cable attachment part of the throttle grip is usually covered by a cover tube fixed to the bundle, but conventionally, this cover tube is split into two parts, and when installing or removing the throttle cable, the cover tube is covered with a cover tube fixed to the bundle. I had to disassemble the tube.

In addition, some models allow the installation and removal of the throttle cable without disassembling the cover tube, but this is limited to models where the throttle cable consists of only one cable on the tension side. .

The present invention was developed in view of the above circumstances, and even if the throttle cable consists of two cables, one on the tension side and one on the return side, it can be easily installed without disassembling the cover tube. An object of the present invention is to provide a mounting device that can be removed.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a bar handle of a vehicle such as a motorcycle or a snowmobile, 2 is a throttle grip rotatably attached to the end of the handle 1;
The inner end of the handle 1 , that is, the connecting portion between the two elements 1 and 2 is covered by a cover tube 3 fixed to the handle 1 .

As shown in FIG. 2, the cover tube 3 is composed of two component members 3A and 3B that can be separated in the circumferential direction, and in the embodiment, it is equipped with a headlight knob 4 and a direction indicator knob 5. It also serves as a switch box.

On the outer periphery of the inner end of the grip 2, three protrusions 8, 9, 10 are formed at intervals in the circumferential direction to form first and second locking recesses 6, 7, which will be described later. As shown in FIGS. 4 and 5, the projections 8 and 10 on both ends abut against stoppers 11 formed on the cover tube 3, thereby restricting rotation of the grip 2 by more than one rotation. .

That is, the stopper 11 is formed by making the lower end wall of the component 3A thicker so as to form a step with respect to the lower end wall of the other component 3B, and the stopper 11 has a tapered inner periphery. The surface 11a is a first contact surface (see FIG. 4) that the tapered outer peripheral surface 8a of the protrusion 8 comes into contact with,
Further, the end surface 11b of the stopper 11 is connected to the end surface 1 of the protrusion 10.
0a is the second abutting surface (see FIG. 5).

The end surfaces 11a and llb of the stopper 11 abut against the outer circumferential surface 8a of the protrusion 8 and the end surface 10a of the protrusion 10 because of the throttle cable outer 18, 19 for assembly purposes, as shown in FIG. This only applies when the parts are protruded outward from when the assembly is completed.

Once the assembly is completed, the tips 18a, 19a of the throttle cable outer 18, 19 will function as a stopper, as shown in FIG.

The first locking recess 6 is formed between the projections 8 and 9, and the second locking recess 7 is formed between the projections 9 and 10. An inch spherical end 12.13 is removably inserted.

In order to prevent the spherical ends 12 and 13 from coming off,
Elastically deformable lip portions 9a and 9b are formed on both circumferential end surfaces of the protrusion 9, respectively.

Further, the end surfaces of the protrusions 8 and 10 facing the locking recesses 6 and 7 are slightly inclined, that is, both end surfaces 8b and 10b are the locking recesses 6 and 10, respectively.
They are inclined so as to approach each other toward the open ends of the openings 7.

On the other hand, first and second insertion holes 14.15 are opened in the cover tube 3 at its lower end, substantially parallel to each other.
3 is said to be large enough to pass through.

Further, the first insertion port 14 faces the first locking recess 6 when the grip 2 is located at the end of its unidirectional rotational stroke (clockwise stroke end in FIG. 2), and the second insertion port 15 faces the first locking recess 6. , the grip 2 is in a positional relationship such that it faces the second locking recess 7 when it is located at the end of the rotation stroke in the other direction.

In the figure, 16 is a return side throttle cable inner having a spherical end 12, and 17 is a tension side throttle cable inner having a spherical end 13.

The former 16 extends from a carburetor (not shown), passes through the first insertion opening 14, and then passes along the outer periphery of the grip 2 and through the guide groove 8c of the projection 8 (see FIG. 2) to the spherical end 12. Similarly, the latter 17 extends from the carburetor, passes through the second insertion port 15, and then continues along the outer periphery of the grip 2 and through the guide groove 10c of the protrusion 10 to the spherical end 13. .

The return side throttle cable outer 18 is fixed to the cover tube 3 with a set nut 20 with its distal end 18a slightly protruding into the cover tube 3.

Similarly, the tension side throttle cable outer 19 is also fixed to the cover tube 3 with a set nut 21 with its distal end 19a slightly protruding into the cover tube 3.

In the installed state where both throttle cable outer parts 18 and 19 are fixed to the cover tube 3 in this way, the tips 18a and 19a act as stoppers that determine the rotational stroke end of the grip 2, regardless of the stopper 11. It looks like this.

Next, the installation procedure for both throttle cables will be explained.

First, as shown in FIG. 4, the grip 2 is positioned at the end of its one-way rotation stroke, and the spherical end 12 of the return-side throttle cable inner 16 is passed through the first insertion hole 14 and then inserted into the first engagement position. Shallowly fit into the stop recess 6.

When the grip 2 is rotated from this state toward the end of the rotation stroke in the other direction, the spherical end 12 will fit deeply into the first locking recess 6 due to the slope of the end surface 8b of the protrusion 8. fully locked.

Thereafter, by fixing the return side throttle cable outer 18 to the cover tube 3 using the set nut 20, the installation of the return side throttle cable is completed.

Next, as shown in FIG. 5, the grip 2 is positioned at the end of the rotation stroke in the other direction, and the tension side throttle cable is then attached in the same manner as the return side throttle cable.

After the installation of both throttle cables is completed, as shown in Fig. 2, the throttle cable outer 18.
Due to the stopper action of the tip 18a*19a of 9,
During rotation of the grip 2, the insertion holes 14 and 15 do not face the locking recesses 6 and 7, and the spherical ends 12 and 13
will not come off from the locking recess 6°7.

Of course, both throttle cables can be removed by following the installation procedure in reverse order.

As is clear from the above description, the present invention allows both the tension side and return side throttle cables to be easily attached and removed without disassembling the cover tube.

Furthermore, since the ends of both throttle cable inches are spherical, the orientation does not matter when fitting them into the locking recesses, making the above-mentioned installation process much easier.
