Abstract

<P>PROBLEM TO BE SOLVED: To provide a three-wheeler having two front wheels which is easy to steer and stable. <P>SOLUTION: In the three-wheeler having two front wheels, front wheel portions of a two-wheeler are divided into right and left portions. Right and left handlebars are turned by the same angle so as to change the advancing direction, and moved in a relatively vertical direction while keeping parallel to each other in the axis of rotation. By adjusting the vertical deviation of the right and left handlebars, the inclination of a vehicle body is controlled. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

The present invention mainly relates to a portion for steering a vehicle body represented by a handle or the like in a bicycle or a motorcycle, and a steered wheel.

In general, tricycles have left and right stability, but the body cannot be tilted.

On the other hand, a two-wheeled vehicle such as a bicycle or a motorcycle can tilt the vehicle body, but it is difficult to balance the left and right.

As described above, a general tricycle is difficult to roll even when it is stationary, and anyone can ride it. However, since the vehicle body does not tilt, exercise ability such as turning performance is limited.

Tricycles are easily affected by road conditions and are stable when there is no undulation on the ground, but they are difficult to balance on rough or inclined roads, and it is difficult to reestablish once the balance is lost.

On the other hand, in the case of a two-wheeled vehicle, it is not affected by the road surface as much as a three-wheeled vehicle, and the degree of freedom of movement is high.
However, it is difficult to maintain the posture, and learning is required.
In addition, a certain speed is required to travel, and the balance is lost as the speed decreases.
In a stationary state, your feet will be on the ground.

In the case of a bicycle, it may be difficult to ride.
Some people are unable to ride bicycles, and even if they are able to ride, there are many people who are dangerous for their daily feet.

In general, a two-wheeled vehicle cannot cover a driver like a car with a vehicle body because of the need to put a foot on the ground.
For this reason, it becomes painful to get wet when it rains or snow, and to drive even if the temperature is hot or cold.
It is also difficult to attach speakers and air conditioners.

In order to solve the above problems, a vehicle steering mechanism that can stabilize the posture of the vehicle body while maintaining high motion performance is required.

In this case, in order to solve these problems, the steering part represented by the steering wheel was made independent on the left and right, and a steering wheel was attached to each.
In order to change the traveling direction of the car body, both wheels are linked to make the same angle, but the relative position can be shifted up and down while keeping both axes parallel to the axis of rotation. To do.
When the vehicle body is tilted, the left and right sides of the handle part are shifted up and down, and the inclination of the vehicle body can be controlled by adjusting the difference by the force of the hand or foot.
Even in a stationary state, as long as the left and right handles are controlled, it will not fall down, so there is no need to put your feet on the ground.

As an example of the above application, the steering wheel can be moved by foot instead of steering the handle by hand.

In addition, when the front wheels cannot be steered, the above mechanism can be used for the rear wheels.

According to the present invention, it is possible to provide a bicycle that can ensure high safety even for a person who cannot technically ride or cannot ride a motorcycle.
Also, by supporting both wheels with feet when the prime mover is attached, it is not necessary to put feet on the ground, and it is possible to deal with changes in rain and temperature by covering the driver with the car body like a car .

BEST MODE FOR CARRYING OUT THE INVENTION

The simplest mechanism for realizing the above-described object is to provide a front wheel portion of a conventional two-wheeled vehicle for the left hand and the right hand, respectively, and attach it in parallel to the rotating shaft portion of the frame portion using two horizontal parts.

It is a front view of the present invention. It is a front view at the time of inclining a vehicle body.

Claims (3)

Bicycles and motorcycles with separate handles on the left and right, and tires attached to each.
A steering mechanism that allows the left and right handles to rotate by the same angle in order to change the direction of travel, but can be shifted relative to the axis of rotation. The handle according to claim 1 can be operated with a foot instead of a hand. The structure according to claim 1 or 2 can be formed by a rear wheel.
