Abstract

PROBLEM TO BE SOLVED: To provide a tricycle allowing to enjoy a new ride, driven by a front wheel and steered by a rear wheel. SOLUTION: A driving wheel is pivotably supported by a fork fixed to a front part of a frame, and twin casters having a turnable spindle are fitted to a backward part of the frame with the spindle in an inclined manner. The inclination of the frame in the right-to-left direction is interlocked with the advancing direction of the twin casters, and the tricycle can be traveled straight by keeping the frame upright, and turned in the right direction or the left direction by inclining the frame in the right or left, and a rider can travel the tricycle in a balanced manner by inclining his upper body to the side opposite to the inclination of the frame.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a three-wheeled bicycle driven by front wheels and steered by rear wheels.

[0002]

2. Description of the Related Art A conventional three-wheeled bicycle driven by front wheels and steered by rear wheels includes a single-wheel or twin-wheel caster,
Attach to the rear of the frame so that the spindle is vertical,
It is connected to a steering wheel via an operating mechanism, and the passenger turns the steering wheel and turns the support shaft of the caster clockwise or counterclockwise to determine the traveling direction.

[0003]

Problems to be Solved by the Invention The three-wheeled bicycle of this type is limited to vehicles for infants with poor balance ability because the body does not swing left and right, and can be enjoyed by young people and adults. Was not.

[0004]

Means for Solving the Problems In order to solve this problem, the present invention secures a grip 5 and a fork 6 to a front portion of a frame 2, and supports a driving wheel 7 on the fork 6,
Attach saddle 1 on top of frame 2
A rear wheel is provided with a twin wheel caster 4 having a rotatable support shaft 3 with the support shaft 3 inclined forward.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In a three-wheeled bicycle according to the present invention, when a drive wheel 7 is a front wheel, a two-wheel caster 4 is a rear wheel, and a frame 2 stands upright with respect to the ground, the traveling direction of the two-wheel caster 4 is Go in the same direction and go straight. As shown in FIG. 2, when the frame 2 tilts to the right with respect to the ground, the two-wheel casters 4 rotate clockwise around the support shaft 3, and the traveling direction of the two-wheel casters 4 The tricycle is turned to the right, and as the tricycle progresses, the rear wheel turns right and the tricycle turns left. When the frame 2 is tilted to the left with respect to the ground, the two-wheel casters 4 rotate counterclockwise around the support shaft 3, and the traveling direction of the two-wheel casters 4 is The tricycle is turned to the left, and as the tricycle progresses, the rear wheel turns left and the tricycle turns right. The passenger leans his / her upper body to the opposite side of the inclination of the frame 2 and travels while maintaining a balance.

[0006]

[Effect of the Invention] While maintaining the right and left balance with the upper body,
The straight running with the frame upright, the upper body tilted greatly to the turning side, and the frame turning to the reverse turning side to change direction is rich in sportiness and full of lightness. It is a vehicle for a wide audience that is not biased toward the age group.

[0007] In addition, a vehicle of a non-conventional type requires a considerable amount of practice before the rider can handle it. In this three-wheeled bicycle, when turning to the left, the upper body is tilted to the left and to the right. When turning, tilt your upper body to the right,
The balance of the upper body is the same as for a two-wheeled bicycle, so there is no sense of incongruity and you can ride with a little practice.
