2. Description of the Related Art Generally, a gear change of a motorcycle is performed by a driver gripping a clutch lever on the left side of a steering wheel to disengage a clutch, and then stepping on a shift pedal and gradually rotating a shift drum. However, an example in which such a gear shifting operation is performed by hand is disclosed in, for example, Japanese Utility Model Publication No. 1-39752.

The motorcycle described in the above publication has an electric transmission, a clutch lever is pivotally attached to a handle so as to be rotatable in a direction for pulling a clutch wire, and is oscillated in a direction intersecting with the direction. It is movably supported.

In gear shifting, the driver grips the clutch lever and rotates it in the pulling direction of the clutch wire to disconnect the clutch, and in this state, swings the clutch lever in the intersecting direction. By this operation, a switch for switching the circuit of the electric transmission is operated to obtain a desired gear shift operation.

In Japanese Utility Model Publication No. 1-41679, a movable portion is formed by a handle grip and a clutch lever, and a fixed portion is formed by a handle bar.
An operation mechanism of the electric transmission is shown in which the circuit of the electric transmission is switched by slidingly moving the movable portion in the axial direction with respect to the fixed portion.

[0006]

[Problems to be Solved] However, while steering with the steering wheel while the vehicle is traveling, the clutch lever grasped together with the steering wheel grip is swung in the crossing direction,
Alternatively, it is not always easy to slide the handle grip and the clutch lever in the axial direction with respect to the handle bar.

Therefore, the present invention is intended to provide a rod-shaped handle for a vehicle having an operating element which can be operated very easily with the thumb while holding the handle grip.

[0008]

Therefore, in the present invention, in a rod-shaped handle for a vehicle having a handle grip at an end thereof, a rod-shaped operator extending in a direction substantially parallel to the axis of the handle is provided. Is provided so as to be movable in the direction, the outer end portion of the operator is located on the lower front side near the inner end portion of the handle grip, and an operation portion for operating the operator is formed at the outer end portion. .

Grasping of the handle grip is performed by placing all fingers of the hand along the peripheral surface of the grip, and particularly grasping by the thumb is performed at the base portion thereof. And in order to grasp the handle grip firmly, it is important that the base of the thumb always grasps the handle grip.

When the handle grip is firmly gripped in this manner, the tip of the thumb projects forward and downward near the inner end (center side of the vehicle body) of the handle grip, and can freely bend at the joint. According to the present invention, since the operation portion of the operator is located at the position of the tip of the thumb, the operator can extremely easily move the operator by the bending motion of the tip of the thumb while firmly gripping the handle grip. It can be operated by moving it in any direction.

As shown in FIG. 3, the operator 7 further slidably extends through the collar 4 of the handle grip 3 to the handle grip 3 side, and is bent downward at a position relatively close to the collar 4 for operation. It is part 12. The operation portion 12 is also located on the lower front side of the handle grip 3, and as shown in FIG. 4, when the driver's left hand 13 grips the handle grip 3, the tip portion of the thumb 14 engages with the operation portion 12. . With the handle grip 3 held as shown in the figure, the tip of the thumb can be freely moved to the left (to the right in FIG. 4) by the bending motion of the indirect portion, and thus the operator 7 is moved by such a movement. It can be easily slid to the left.

A joint piece 15 is screwed to the other end of the operator 7 and fixed by a nut 16. FIG. 9 is a front view of the joint piece 15, and FIG. 10 is a top view thereof. The operator 7 is pivotally attached to the end of one arm of a lever piece 17 via a joint piece 15, and the lever piece 17 is pivotally supported at its central portion by a holder 18 fixed to the handlebar 2. Has been done.

Next, the structure of the assembly including the joint piece 15, the lever piece 17 and the holder 18 will be described with reference to FIGS. Note that this structure is easier to understand by referring to the exploded view of the parts in FIG.

The holder 18 is a bolt similar to the holder 9 described above.
The upper and lower holder pieces 18a and 18b are fastened and fixed to the handlebar 2 by 19. 5 is a side view of the lower holder piece 18b as seen from the handle grip 3 side,
FIG. 6 is a bottom view thereof. The holder piece 18b bulges toward the handle grip 3 at a position directly below the handlebar 2, and a pivot 20 is provided on the lower surface of the bulge portion. Then, as shown in FIGS. 7 and 8, an intermediate portion of the lever portion piece 17 is pivotally attached to the pivot shaft 20.

The lever piece 17 is rotatably supported by a support bolt 21 screwed to the pivot shaft 20 via a washer 22, and extends in the front-rear direction substantially at right angles to the handlebar 2. The joint piece 15 is pivotally attached to the tip of the arm 17a in front of the lever piece 17. Ie joint pieces
The distal end of the arm 17a is inserted into a bifurcated distal end of the arm 15 (see FIG. 9), and the two are rotatably connected to each other by a pin 23 that vertically penetrates the arm 17a.

The holder piece 18b also has projecting pieces 24a, 24b projecting downward at the front and rear portions thereof, respectively.
Are provided integrally. A switch 26, which will be described later, is fitted and mounted in a mounting hole 25 provided in the projecting piece 24b, and an operating piece 27 of the switch 26 projects toward the lever piece 17 side and abuts on the tip of the arm 17b. There is. Actuating piece 27
Is a switch provided by a spring provided in the switch 26.
Since it is biased in the direction to project from 26, the lever
17 is urged by the operating piece 27 so as to rotate around the pivot 20 in the direction opposite to the arrow a (FIGS. 1 and 8).

On the other hand, the front protruding piece 24a is provided with a screw hole 28, and the tip end of the adjusting screw 29 screwed into the screw hole 28 receives the arm 17a of the lever piece 17, and as described above. The biased position of the biased lever piece 17 is defined. This position can be arbitrarily adjusted by the adjusting screw 29.

When the manipulator 7 is moved to the left with the thumb as described with reference to FIG. 4, the lever piece 17 is rotated around the pivot 20 in the direction of arrow a, and the tip of the arm 17b is moved to the actuating piece 27.
Is pushed into the switch 26, and the switch 26 operates.

The switch 26 in this embodiment is a switch for opening and closing the fluid circuit, and is connected to the air pipe 30 and the air pipe 31 as shown in FIG. 11, and normally shuts off the conduction between the air pipes 30 and 31. However, when the operating piece 27 is pushed by the lever piece 17, both pipes are brought into conduction and air flows from the air pipe 30 to the air pipe 31.

The air pipes 30 and 31 are connected to the speed change operation system schematically shown in an exploded perspective view in FIG. In FIG. 12, 32 is a motorcycle body frame, and 33 is an engine mounted on the vehicle body frame 32. Body frame 32
A change pedal 34 for switching the transmission gears is normally provided on the lower part of the left side (the right side in the drawing; the same applies hereinafter).

An air tank 35 is attached to the left side surface of the engine 33, and the air pipe 30 is connected to the air tank 35. On the other hand, on the right side of the engine 33 is an air pump.
36 is installed. The air pump 36 is driven by the battery 37, pressurizes the air sucked from the suction port 36 a, and sends it to the air tank 35 through the discharge pipe 38. Air pump 36
Is controlled by a signal from the pressure detection unit 35a of the air tank 35, and the internal pressure of the air tank 35 is always maintained at a predetermined value.

Two pipes 40 and 41 are connected to the air tank 35 via a main valve 39. The air pipe 31 is connected to the main valve 39. The main valve 39 normally shuts off the communication between the air tank 35 and the pipes 40 and 41. However, when the pressure air in the air tank 35 is sent through the air pipe 30, the switch 26, and the air pipe 31, it opens due to the pressure of the air, and the pipe Connect 40 and 41 to the air tank 35.

A pipe 40 is a cylinder of a cylinder device 42 for vertically connecting the vehicle body frame 32 and the change pedal 34.
When the cylinder 42a is connected to the cylinder 42a and air is supplied to the cylinder 42a through the pipe 40, the piston rod 42b moves up to swing the change pedal 34 upward.

The pipe 41 is connected to an ignition cutoff switch 43. The ignition cutoff switch 43 operates by the pressure of the air sent through the pipe 41 to temporarily cause the engine 33 to misfire.

Since this embodiment is constructed as described above, when the driver moves the operating element 7 to the left with his / her thumb while traveling, the switch 26 is actuated and the air pipe 30 and the air pipe 31 are connected. , The air in the air tank 35 is supplied to the main valve 39, and the main pipe 39 opens. Thus, air is sent to the cylinder 42a through the pipe 40 and the piston rod 42b rises to swing the change pedal 34 upward, whereby the meshing of the transmission gear is switched to the high speed side. This operation is conventionally performed by pushing up the change pedal 34 with a foot. At this time, air is also sent to the ignition cutoff switch 43 through the pipe 41, and the engine 33 temporarily loses fire. Therefore, the engine torque acting on the transmission gear is reduced, so that even if the clutch lever 6 does not disengage the clutch. Gear change is performed smoothly.

The change pedal 34 may be depressed with the foot when the transmission gear is switched to the low speed side. This operation is simpler and easier than the operation of pushing up the change pedal 34 with the tip of the foot. At this time, the air in the cylinder 42a is discharged through an appropriate discharge valve (not shown).

As described above, in the above-described embodiment, only the shift gear is switched to the high speed side by the operator 7 manually, but for example, a switch for switching the circuit of the electric transmission is operated by the operator 7. It is also possible to switch to the low speed side by operating the operating element 7.

Further, it is needless to say that the operator in the present invention is not limited to the operator for shifting operation, and can be applied as an operator for other operations.

[0032]

According to the present invention, the driver can very easily operate the operating element while the driver grips the steering wheel grip while the vehicle is traveling.
