Description

[Detailed Description of the Invention] The present invention relates to an operating lever used to operate a brake device or a clutch device in two-wheeled vehicles, three-wheeled vehicles, etc.

Generally, in this type of operating lever, the lever body is pivotally attached to a fixed member that is fixed to the handlebar, facing the grip of the handlebar, and the lever body is hooked with a finger to perform a pulling operation in the direction of the grip. It's summery.

The end of this lever body is provided with an end protruding ball part, which positions the fingers during operation and provides a good grasping condition.
This prevents the fingers from coming off the end of the lever body even if the fingers are misaligned.

By the way, when the protruding ball part at the end having such a function acts as a weight and causes vibrations in the vehicle body while driving, it becomes a cause of increasing the vibration of the control lever, and furthermore, this vibration is received by the pivot part of the lever body. This requires strength in this part, and it is possible that prying may occur.

The present invention has been made in view of the above circumstances, and includes a lever body having a protruding ball portion at its end facing the grip of the handlebar, which is pivotally attached to a fixing member fixed to the handlebar. An operating lever for a two-wheeled vehicle, etc., which is pulled in the grip direction by hooking a finger on the lever body, characterized in that a notch is formed in the protruding spherical portion at the end of the lever body, leaving at least a spherical portion on the non-grip side. shall be.

The purpose of the present invention is to form a notch without impairing the function of the end protruding ball provided at the end of the lever body, thereby reducing the weight of the lever body and reducing the vibration of the vehicle body while driving. A two-wheeled vehicle that suppresses the vibration of the lever body caused by the lever body, eliminates the need for excessive rigidity in the pivot joint of the lever body, and reduces the occurrence of prying, etc., so that it can operate satisfactorily for a long period of time. etc. to provide operating levers.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

A grip 2 is attached to the rear end of the handlebar 1, and a master cylinder 4 is attached to the front of the grip 2 on the handlebar 1 by a handle holder 3. The lever body 5 is the operating lever mounting part 6 of this master cylinder 4.
It is pivotally connected to the grip 2 by a lever support pin bolt 7, and is rotatable in the direction of the grip 2.

A protruding ball portion 8 is provided at the tip of the lever body 5. This protruding ball at the end is used to position the driver's fingers when the driver grips the grip 2 of the handlebar 1 with the palm of the hand and hangs the lever body 5 in this grasped state. It functions to prevent the fingers from slipping, which may occur when the grip is pulled in two directions.

The present invention is based on the protruding ball portion 8 at the end of the lever body 5.
A further feature is that a cutout portion 8b is formed leaving the spherical portion 8a at least on the non-grip side. As a result, the end protruding ball part 8 becomes lightweight without impairing the above-mentioned function, and the weight of the tip of the lever body 5 can be effectively reduced. In other words, the non-grip side of the protruding end ball portion 8 is the part that the fingers come into contact with, and by forming a cutout in this part, it is possible to position the fingers in the above-mentioned grasping state, or to prevent the fingers from slipping during operation. is damaged. The notch 8b in the embodiment shown in FIGS. 1 and 2 is a blind hole formed vertically upward from the lower side of the lever main body 5.

FIGS. 3 to 6 show other embodiments of the notch 8b formed in the protruding ball portion 8 at the end of the lever body 5. FIG. 3 shows a vertical through hole formed in the end protruding ball part 8, which serves as a notch 8b, and FIG. A horizontal hole is formed in the direction, and a fifth hole is formed in the direction.
In this figure and FIG. 6, a notch 8b is formed by horizontally cutting the end protruding ball part 8 from the grip side in accordance with the shape of the non-grip spherical part 8a.

Next, the operation of this embodiment will be explained. While driving, the driver grasps the grip 2 of the handlebar 1 with his/her palm, and when applying the brakes while in this grip state, the driver quickly hooks his/her fingers onto the lever body 5. At this time, even if the fingers come off the center of the lever main body 5 and hang on the tip side, they are positioned by the end protruding ball part 8 and can be gripped reliably.

Then, the user pulls the lever main body 5 in the direction of the grip 2 with his or her fingers, pushes the piston of the master cylinder 4, and supplies pressurized fluid to the brake device to perform braking. When pulling this lever body 5 in the grip 2 direction,
Even if the finger and finger are displaced toward the distal end, the protruding ball portion 8 at the end prevents the finger from shifting, making operation reliable and safe.

While the vehicle is running, the vehicle body vibrates due to the unevenness of the road surface, and the lever body 5 also vibrates along with this. At this time, since the protruding ball portion 8 at the end of the lever body 5 is made lightweight by the notch portion 8b, the function of the weight is reduced and vibrations are suppressed. Therefore, the load applied to the operating lever mounting portion 6 is suppressed, and the operating lever mounting portion 6
The lever body 5 is not made to have more rigidity than necessary, and the pivoting portion of the lever body 5 is less likely to be strained, so that it can operate satisfactorily for a long period of time.

Furthermore, although the above embodiment has been described with respect to an operating lever used in a brake device, the present invention can be similarly applied to an operating lever used in a clutch device attached to the left handlebar. Further, in the embodiment described above, the fixing member to which the lever body is pivotally attached is the master cylinder 4, but the fixing member is not limited to this, and any fixing member that is fixed to the handlebar 1 may be used.

As described above, according to the present invention, since the notch is formed in the end protruding ball part of the lever body, leaving at least the spherical part on the non-grip side, it is easy to position the fingers when operating the end projecting ball part, or The tip of the lever body is made lighter without compromising the anti-slip function of the fingers, reducing the vibration of the control lever that occurs when driving. This eliminates the need for the pivoting part of the operating lever to have more rigidity than necessary, and also effectively prevents twisting between the operating lever and the shaft that rotatably supports it, allowing the operating lever to remain in good condition for a long time. can operate.
