Description

[Detailed Description of the Invention] The present invention relates to a bicycle operating device for motorcycles, tricycles, etc.

When installing a brake lever on a motorcycle, etc.,
A tension knob is provided at the center of the rear face of the front cover and is pulled to operate the yoke, but since this is far from the handlebar area, improvements are desired in terms of improved operability.

On the other hand, a model with a tire yoke lever installed around the handle has also been proposed, and conventionally the yoke lever is provided on the support bracket of the clutch lever, but with this, the yoke lever must be pivoted to the bracket, making assembly difficult. In particular, there is an electrical switch housing between the bracket and the handle grip, and since the choke lever faces beyond this, the choke lever is further away from the position where the grip is gripped, further improving operability. is desired.

The present invention was made to improve the above-mentioned problems, and its purpose is to attach a switch lever to the switch housing provided at the end of the handle in front of the grip so that it can rotate around the circumference of the handle; It is an object of the present invention to provide a yoke operating device for a motorcycle, etc., which is easy to assemble and further improves operability.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a plan view of the motorcycle handle part, Figure 2
The figure is an enlarged cross-sectional view of the teak lever part, and FIG. 3 is a view taken in the direction of line 3-3 in FIG. 2.

Reference numeral 1 designates a top bridge, as is known, which is connected to the upper ends of the left and right fork pipes of a front fork that supports the front wheels, and the top bridge 1 is pivotally connected to a head tube on the vehicle body side by a steering stem. The base of the handle pipe 2 is tied onto the top bridge 1, and although the embodiment shows a separate type in which the left and right handle pipes are divided, a single type may also be used. A grip 3 is provided on the outer periphery of the downstream or outer end of the handle pipe 2, and a handle switch housing 4 is provided adjacent to this on the upstream side in front of this, and a holder for a clutch lever 5 is further provided on the upstream side of this. In this embodiment, since the clutch lever is of a hydraulic type, a clutch master cylinder 7 is attached to the holder 6, and the clutch lever 5 is pivotally mounted to this via a holder 8 so as to be swingable.

The handle switch housing 4 is equipped with a horn switch, headlight switching, high beam, low beam switching, and other switches.
The handle pipe 2 is usually formed of two members 41 and 42 having dividing surfaces in the radial direction of the handle pipe, and is connected to the pipe by screws 44 and 44 passing through both parts so as to hold the handle pipe 2. housing 4
is provided with end walls 4a and 4b at the front and rear in the axial direction of the pipe 2, the outer end (rear end) wall 4b contacts the upstream end flange 3a of the grip 3 on the downstream side, and the peripheral part of the inner end (front end) wall 4a is provided with a protruding frame 8 extending in the upstream direction, the protruding frame 8 is provided with an inner diameter part 9 having a predetermined length in the axial direction, the inner diameter part 9 is open in the upstream direction, and is closed in the downstream direction by a wall 4a. There is. A circular large-diameter recess 10 is provided at the downstream end of the inner diameter portion 9, and the downstream end of the recess 10 is constituted by a wall 4a.

Reference numeral 11 denotes a chiyoke lever, which is rotatably fitted to the outer periphery of the pipe 2 at the inner diameter part 12a of its base 12;
The base portion 12 is provided with a boss portion 13 that protrudes in the downstream direction and that fits into the inner diameter portion 9 of the projecting frame 8 described above, and the annular engagement flange portion 14 that engages with the large diameter recess 10 is provided at the downstream end of the boss portion 13. and two members 41, 4 of the housing 4.
2 from the outside, and the flange portion 14 is inserted into the recessed portion 10.
Fitting the boss portion 13 into the inner diameter portion 9 while engaging with the
The axial direction of the lever 11 is restricted by the engagement of these 14 and 10. An annular recess 1 on the downstream side of the flange portion 14
5 is provided, and a cable 16 is wound around this, the end of which is connected to the lever 11 side by a tie 17, and the cable 16 is led out from a guide portion protection member 43 provided on one member 42 of the housing 4. , connected to the carburetor valve lever. The guide portion 43 covers the movable range of the cable 16 and prevents mud etc. from adhering to the movable portion of the cable 16. A lever portion 18 is provided that protrudes outward from a portion of the base portion 12.
protrudes from the outer periphery of the housing 4, and the lever 11 is provided integrally with the upstream side of the housing 4.

In the above, the switch lever is provided upstream and integrally with the switch housing, and the lever part 18 is provided protruding from the outer periphery of the upstream part of the switch housing 4, and the lever part 18 is pressed with a finger and rotated around the pipe two times to operate the switch housing. I do. Therefore, when you hold the grip and operate the switch, you can operate the yoke in the same position, improving operability.Also, since the lever is configured to rotate around two circumferences of the handle pipe, a separate rotation fulcrum is required. In addition, the switch lever 11 can be assembled by assembling the switch housing to the pipe 2, and since the movable part of the switch lever is not built into the switch housing 4, there is no need for a mounting means for the switch lever itself. In addition to reducing the number of parts and installation man-hours, the interior of the switch housing 4 can be made waterproof, and the switch lever is integrated with the switch housing, and its own screws are not visible on the outside, improving the appearance. can be done.

The present invention has many advantages as mentioned above.
