Abstract

PROBLEM TO BE SOLVED: To readily enjoy motor sports as manual cycling sports by constituting a tricycle into divided structure of an operating part for steering and a driving part for traveling and stopping. SOLUTION: A body frame 3 is constituted by three-point support of a pair of front wheels and a rear wheel 8. An operator's seat 4 is fitted to the frame 3 so as to be longitudinally adjustable in position backward from between the front wheels. A driver's seat 7 is fitted to the upper part of the real wheel 8 so as to be vertically adjustable in position and a driver's handlebars are provided at the front part. One person is seated on the operator's seat 4 and grips a steering wheel 1 to perform steering operation, and the other person is seated on the driver's seat 7 and grips the driver's handlebars and presses pedals 6 to drive the rear wheel 8. Because of not being able to run well unless two persons are in harmony, enjoyment as sports is high with outdoor leisureness while being gentle to nature because of manual force.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a three-wheeled bicycle.

[0002]

2. Description of the Related Art A conventional two-seater three-wheeled bicycle has a position between a front wheel of a frame supported by a pair of small-diameter front wheels and a large-diameter rear wheel, as described in, for example, Japanese Utility Model Publication No. 4-3918. A seat mounting rail lower than the upper part of the rear wheel is provided, and a seat is mounted at a position close to the rear wheel from immediately above the front wheel of the seat mounting rail, and the front wheel and the steering mechanism are mounted at a position forward of the front wheel of the frame. With the handle interlocked via
A foot-operated drive mechanism is attached to the front lower part of the handle, and the drive mechanism and the rear wheel are linked by a chain via an intermediate shaft pivoted between the front wheel and the rear wheel of the frame. A rear seat is provided at a position above and behind the rear, and an intermediate shaft is provided with a detachable pedal. As described above, there are three types of ordinary bicycles for two-seaters, but there is no one that satisfies leisure, sports, and functionality like a go-kart.

[0003]

In a conventional three-wheeled bicycle, a chain is provided under a driver's seat, and a drive system is provided in front of a front wheel.
It has the drawback that it lacks sports and functionality and is far from attractive as a go-kart.

An object of the present invention is to provide a three-wheeled bicycle in which motor sports such as go-kart and racing car can be easily enjoyed as cycle sports by human power.

[0005]

In order to achieve the above object, a three-wheeled bicycle according to the present invention has a structure in which a driving part for steering the function of the three-wheeled bicycle and a driving part for running or stopping are divided. .

That is, the driving section is located at the front of the vehicle body frame, and the driving section is disposed at the rear of the body frame, so that the visibility of the driving section and the power of the driving section can be ensured.

In addition, the position of the driver's seat is mounted slightly behind the front wheels and lower than the upper portion of the front wheels so that the front and rear can be adjusted.
A steering wheel interlocked with a front wheel via a steering mechanism is attached to a front portion of the driver's seat.

Further, the position of the driver's seat is mounted on the upper portion of the rear wheel so as to be vertically adjustable, a foot pedal for driving is provided in front of the rear wheel, and a driver handle is provided in front of the driver's seat. A brake lever is attached to the driver's handle. With the above configuration, the go-kart exhibits the leisure, sport, and functionality.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. 1, 2 and 3, a body frame 3 of a three-wheeled bicycle is formed by three-point support of a pair of front wheels 2 and rear wheels 8. A pair of front wheels 2 is incorporated in a bearing 15 at the front part of the body frame 3, and is attached to the body frame 3 by a king pin 16. Handle 1
Is connected by a link 17 to a steering mechanism 12 supported by a handle support 14 and connecting a bearing 15.

A driver's seat 4 is mounted on the frame 3 so that the position of the front wheel 2 can be adjusted back and forth behind the front wheels. A rear wheel 8 is attached to a rear portion of the frame 3, and a driving chain gear 9 is attached to a foot pedal 6 provided in front of the rear wheel 8, and a driven chain gear 10 attached to the center of the rear wheel 8. And the drive chain 11.

The driver's seat 7 is mounted on the upper portion of the rear wheel 8 so that the vertical position can be adjusted freely. A driver's handle 5 is provided in the front part, and a brake lever 13 is attached to the handle 5.

With the above-described configuration, one person can enter the driver's seat 4
, The steering wheel 1 is gripped and the steering operation is performed. Another person is seated on the driver's seat 4 and the driver's handle 5 is gripped.
When the pedal 6 is stepped on, the rear wheel 8 is driven to advance. Further, the brake lever 13 attached to the driver handle 5 is pulled and stopped. Also, when riding alone, if the auxiliary handle 18 is attached, it can be driven on the drive side

[0013]

Since the present invention is configured as described above, it has the following effects.

Since the frame is supported by a pair of left and right front wheels and one rear wheel, and there is no drive system below the driver's seat, the driver's seat is at an extremely low position, so that stability during traveling is established.

Further, since the driver's seat is low, the ground is close to the driver, and the driver can enjoy a sense of speed higher than the actual speed.

Further, since the vehicle is driven with the front wheels in front, the traveling direction is easy to understand, and it is easy to acquire driving knowledge.

In addition, since the steering operation and the traveling operation are completely separated, it is difficult to run well if two people do not meet each other. Therefore, a cornering technique when running at a speed on a fixed course such as a race. It is a sporty nature of teamwork play of two people.

In addition, it is naturally gentle due to human power and has an outdoor leisure property. When the vehicle is driven by a parent and a child, even if the child drives the vehicle, the driver has the driving and stopping initiative, so that the driver can enjoy the driving safely.
