Abstract

PURPOSE:To provide a handle grip for motorcycle in which the breakage of the grip or the heavy rotating operation of the grip can be minimized when a vehicle is turned sideways. CONSTITUTION:A balancer 4 the outside of which is swollen is spherical form is press-fitted to the end of a bar handle 1, the outer end of a throttle tube 5 to be fitted to the end part of the bar handle 1 is formed in a spherical form to cover the outside of the balancer 4, and an elastic grip 8 is fitted onto the throttle tube 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle grip for a motorcycle.

[0002]

2. Description of the Prior Art A motorcycle has a bar handle extending in the left-right direction at the upper end of a front hawk, and grips attached at both ends of the bar handle so that a rider can grasp the grip and front wheels of the front hawk. It is designed to steer. On the right hand side, the grip is rotatable so that the throttle wire can be wound and the opening / closing operation of the throttle valve can be performed.

The handle grip is, as shown in FIG.
A throttle tube B is rotatably fitted into the tip of the bar handle A, and an elastic grip C is attached to the throttle tube B so that it can be fitted to the grasped hand.
Further, as shown in FIG. 5, a balancer D may be attached to the tip of the bar handle A. In this case, the throttle tube B and the tip of the grip C are holes, and the balancer D is placed outside the grip C. Is projected.

[0004]

As a motorcycle, there is an off-road vehicle called a motocrosser or the like. Since this type of vehicle travels in places with poor road conditions, it often loses balance and falls. When the motorcycle falls down and the motorcycle is fallen down, the grip C portion protruding sideways often comes into contact with the ground and receives an impact. In the case of the one shown in FIG. 4, when an impact is applied, the portion E may be broken, or the outer end of the throttle tube B may be deformed to eliminate the gap F with the bar handle A, so that the grip C cannot be smoothly rotated. .
Further, in the case of the one shown in FIG. 5, the balancer D portion is most likely to be impacted most, but there is a disadvantage that the gap G between the bar handle A and the grip C is clogged with mud, and the grip C is swung heavily.

In view of the above point, the present invention has an object to obtain a handlebar grip of a motorcycle which can reduce the damage of the grip and the heavy turning operation of the grip when the vehicle is turned over.

[0006]

In order to achieve the above object, a handlebar grip of a motorcycle according to the present invention is configured such that a balancer whose outer side is inflated into a spherical shape is press-fitted into the end of the bar handle to press the end of the bar handle. The outer end of the throttle tube that fits in the section is made spherical and covers the outside of the balancer, and the throttle tube is covered with an elastic grip.

Since the outer end of the throttle tube has a spherical shape and covers the balancer, there is no gap, and mud does not enter the rotating portion of the throttle tube and the bar handle. Further, since the outer end of the throttle tube has a spherical shape, it is resistant to impact and is less likely to be deformed. Also, by changing the radius of curvature of the spherical shape of the outer end of the throttle tube and the spherical shape of the balancer, even if the outer end of the throttle tube is deformed, it is possible to secure a gap and prevent surface contact with the balancer. It is possible to prevent the turning operation of the throttle tube from becoming heavy.

[0008]

Embodiments of the present invention will be described below with reference to FIGS. The bar handle 1 extending in the left-right direction has a central portion attached to the upper bracket 3 of the front fork 2. At the tip of the bar handle 1, a balancer 4 whose outside is inflated into a spherical shape is press-fitted and fixed. The balancer 4 is lead,
The vibration of the bar handle 1 is reduced by selecting an appropriate weight such as iron and changing the natural frequency of the bar handle 1. A throttle tube 5 having a spherical outer end is rotatably fitted into an end portion of the bar handle 1. The throttle tube 5 is formed by using a hard synthetic resin or the like. The end of the throttle wire is attached to the collar 6 provided at the inner end, and the throttle wire is wound by rotating the throttle tube 5. The throttle valve can be opened and closed. The inner end of the throttle tube 5 is fixed by the throttle body 7 in the longitudinal direction of the bar handle 1. An elastic grip 8 is attached to the throttle tube 5 so that it fits comfortably in the hand. As for the spherical shape of the balancer 4 and the spherical shape of the throttle tube 5, the radius of the curved surface is changed as shown in FIG. 2 so that the gap between the two spherical shapes changes unevenly.

The throttle tube 5 is a bar handle 1.
Since it covers the entire end of the balancer 4 and the balancer 4, mud does not enter between the throttle tube 5 and the bar handle 1, and the rotating part is not clogged with mud and the movement does not become hard. The outer end of the throttle tube 5 has a spherical shape and is strong against impact and can be deformed little. Further, even if the outer end of the throttle tube 5 is deformed, the radius of the spherical surface of the balancer 4 and the outer end of the throttle tube 5 are changed. Can be less heavy.

[0010]

As described above, since the present invention is configured as described above, there is no gap between the throttle tube 5 and the end portion of the bar handle 1 and the balancer 4, and mud or the like can be removed from the throttle tube 5 and the bar. The handle 1 does not enter the turning portion, and the turning operation does not become heavy due to mud. Further, the outer end of the throttle tube 5 has a spherical shape so that it is resistant to impact and can be prevented from being deformed. And
By changing the radius of the spherical surface of the throttle tube 5 and the balancer 4, even if the throttle tube 5 is deformed due to a large impact, the throttle tube 5 and the balancer 4 need only be in point contact, and the throttle tube 5 can be rotated. Can be prevented from becoming heavy. The thickness of the grip 8 attached to the throttle tube 5 can also be made uniform, and it can be made difficult to tear.
