Description

[Detailed description of the invention] The present invention has a cable end provided at the end of the throttle cable, which is arranged around the axis of the throttle grip, and a pair of engaging pieces provided on the cable winding part, which is elastically applied from the outside in the radial direction. This invention relates to a throttle cable attachment mechanism for a grip for a two-wheeled vehicle, etc., which can be fitted into and fixed to a motorcycle grip.

As shown in Figs. 1 and 2, the conventional throttle cable attachment mechanism for motorcycle grips, etc. is fixed to the inner periphery of the throttle grip 1, rotatably fitted to the rod bundle a, and protrudes from the flange 2 of the grip 1. A pair of engagement pieces 5.6 opposed in the circumferential direction are protruded from the cable winding part 4 formed on the axial circumference of the throttle tube 3, and the inner part of the narrow groove γ between the engagement pieces is enlarged. , throttle cable 1 shown in FIG.
A fitting hole 8 similar to the cross-sectional shape of the cable end 12, such as a cylindrical one provided in a T-shaped intersection, is formed at the end of the cable end 12, and a fitting hole 8 is formed around the outer periphery of the cable winding part 4 to form a lower case 14. The upper case 15 is fixed to a rod a.

Both cases 14 and 15 have inner peripheries formed in a substantially circular shape to allow the retaining piece to rotate 5.60 times, and the lower case 14 has an insertion portion for passing the throttle cable 11 therein from a substantially tangential direction. 16 is integrally provided, and the sleeve 13 of the cable 11 is fixed by a plug 17 that is fitted and fixed from the outside to the insertion portion 16.

Further, the engaging piece 5 is formed long in the circumferential direction so that the inner side of the insertion portion 16 causes an engagement that restrains rotation in the left direction in FIG. It is provided with a circumferential guide groove 9 into which it fits.

In this structure, after fixing the sleeve tube 13 to the lower case 14, the throttle cable 11 and the cable end 12 are pulled out, and the cable 11 is passed through the narrow groove 1 between the engagement pieces 5 and 6 from the outside in the radial direction. While doing so, fit the cable end 12 into the fitting hole 8 from the axial direction, then lower the lower case 1.
4 and the upper case 15 are fixed to the rod 1.

However, since the throttle cable 11 has a fixed length, the cable 11 and the cable end 12 are inserted into the insertion portion 16.
If it is difficult to pull out the cable end 12 sufficiently from the cable end, it is difficult to fit the cable end 12 into the fitting hole 8 by the above operation.

The present invention eliminates such drawbacks and utilizes the elasticity of the material of the throttle tube 3 to elastically engage the retaining piece on the winding direction side, which is formed integrally with the throttle tube 3, which is usually made of a strong elastic resin material. Cable end 1 by joining pieces
2 is improved so that it can be fitted and fixed very easily from the outside in the radial direction, and one embodiment thereof will be described below with reference to FIGS. 4-5.

That is, the engaging piece 6 in the winding direction of the cable 11 shown in FIG.
As clearly shown in FIG. 5, this is an elastic engagement piece 22 which protrudes radially outward from the grip tube 3 in an inverted U shape and utilizes the elasticity of the material of the tube 3.

The elastic engagement piece 22 has a groove 21 in the center, so that the engagement piece 5
This is to increase the bending force of the free end 23 corresponding to a.

Further, the engaging piece 5a is provided with an engaging surface 5b whose outer end has a rake angle slightly inclined toward the engaging piece 22, and the free end 23 has an engaging surface 24 corresponding to the base of the engaging surface 5b. The base of the engaging surface 5b and the engaging surface 24 constitute a fitting hole 25 having a manhole portion 26 on the outside in the radial direction.

According to this configuration, the cable end 12 can be strongly pressed against the manhole 26 from the outside in the radial direction of the throttle tube 30, and the free end 23 of the elastic engagement piece 22 can be elastically bent and inserted into the fitting hole 25. When the insertion is completed, the free end 23 automatically returns to connect the engaging surface 24 to the cable end 1.
2 and presses the end 12 against the base of the engagement surface 4b.

Therefore, no force is applied to the engagement surface 24 of the elastic engagement piece 22 when the throttle cable 11 is wound around the cable winding section 4 and pulled out, and when it is unwound and then unwound.
There is no possibility that the fitting will come off.

As is clear from the description of the embodiments, the present invention provides an engaging piece formed on the cable winding direction side of the cable 110 in the cable winding portion 4 of the throttle tube 3 with elasticity utilizing the elasticity of the material of the tube 3. The engagement piece 22 is provided with an engagement surface 24 at the free end 23 of the engagement piece, which corresponds to the base of the engagement surface 5b of the engagement piece 5a opposite to the elastic engagement piece 22. 24. The manhole 26 is radially outwardly between 5a.
Since the fitting hole 25 is configured to have a diameter, the cable end 12 connected to the throttle cable 11 can be pressed and fitted into the fitting hole 25 from the outside in the radial direction, as shown in FIGS. The various difficulties associated with fitting from the axial direction as in the conventional example can be eliminated, the fitting operation can be simplified, and the winding of the cable 11 can be simplified.
Since no force is applied to the elastic engagement piece 22 during refitting, the cable end 12 can be completely prevented from coming off, and the strength equivalent to the previous attachment connection strength can be maintained.
