Description

The present invention relates to a mobile device such as a bicycle or a wheelchair that propels a seat by swinging it.

Conventional automobiles and wheelchairs have gained propulsion mainly by the power of their hands and feet.
It has been difficult for people with weak limbs, such as elderly people and disabled people, to use cars and wheelchairs.
With the aging of society, it is convenient to have a bicycle or wheelchair that uses the whole body to propel it, not relying solely on the strength of the extremities.

As shown in Patent Document 1, there is a bicycle that obtains a propulsive force by swinging a handle, but arm force is required to move the handle.
At present, there are no bicycles, wheelchairs, or other mobile devices that can swing the entire body to obtain a propulsive force in order to efficiently use the power of the body.

Special table 2003-514712

The present invention realizes a bicycle or a wheelchair that has a simple structure and does not rely on hand force and foot force as in the prior art, but swings and pushes the entire body.

A riding part on which a person rides is coupled to a wheel frame that supports the wheel by a single spindle.
And the person who got on this boarding part rocks the boarding part, and it swings like a pendulum about this support shaft. The reciprocating kinetic energy of this shaking is rotated by a reciprocating rotation conversion mechanism and propelled by rotating the wheel.

Since there is no pedal, it can be designed freely.
Depending on the purpose of use, the position of the oscillating shaft can be changed, and the arrangement of each component can be changed to an optimum form, so that a design with a high degree of freedom can be achieved.
For example, it is a human-powered movement of a free idea such as a shape of a conventional bicycle, a three-wheel type, a four-wheel type, or a type of riding while standing.

In the wheelchair type, the body moves forward while shaking the body, so it does not require arm strength, and even elderly people can move long distances.
The stand-up ride type can be shaken strongly and enables high-speed running. There are also playground elements.

Embodiments will be described below with reference to the drawings.
The wheel frame 200 that rotates and supports the wheel 210 has a rocking bearing 250, and a riding frame 100 on which a person rides is coupled to this through a rocking support shaft 150.
The swing support shaft 150 is provided on the left and right on the same axis, and the riding frame 100 swings freely using the swing support shaft 150 as a swing shaft.
This oscillation is a reciprocating motion with irregular amplitude, which is converted into a rotational motion by a reciprocating rotation converting mechanism OK and coupled to the rotating shaft of the wheel 200.
As a result, the swinging motion of the riding frame 100 is converted into a rotational motion and transmitted to the wheels 210, and the present invention promotes.

FIGS. 1 and 2 show a method of riding in a semi-standing state in which the lower limbs are extended and sitting on the saddle 170, and the swing shaft is positioned at the height of the rider's M around the hip joint. As shown in FIG. 2, when the body is tilted back and forth, the riding frame 100 swings back and forth with the swing support shaft 150 as a fulcrum. This oscillation is a back-and-forth reciprocating motion, which is converted into a rotational motion by a reciprocating reciprocating conversion mechanism OK.

3 and 4 are examples of a wheelchair, which is an example having a swing shaft at a position higher than the center of gravity of the riding frame 100. As a result, it can be swung slowly like a swing, so that disabled persons and elderly people who are difficult to use the power of their limbs can get propulsive power as if they are rowing the whole body.

By moving the whole body, the inertial force works greatly, and it is possible to obtain a larger propulsive force than before, so that it is possible to realize a moving tool with various specifications.

For example, when it is desired to perform a swinging motion quickly to obtain sports-like enjoyment with an emphasis on speed and mobility, the swinging shaft is set near the body center of gravity of the rider M. When the passenger is weak, etc., the swing axis is set far from the center of gravity of the body of the rider M, the swing amplitude is increased slowly like a swing, and the gear ratio of the reciprocating rotation conversion mechanism OK is reduced. For example, a high torque output can be considered.

As shown in FIG. 5, it can also be used for conventional bicycles. The reciprocating motion by the swinging reciprocating force of the riding frame 100 is propelled to the chain T and the sprocket S, which is a reciprocating rotation converting mechanism, as a rotational force.

Incidentally, the reciprocating rotation conversion mechanism may use a crank mechanism, a combination of a chain and a free hub, or a pinion rack mechanism, but the reciprocating motion by swinging of the present invention is often an irregular stroke, so that it can be adapted to this. In addition, it is desirable to provide a reciprocating rotation conversion mechanism that can convert irregular amplitude into rotational motion and convert both forward and backward swinging reciprocating force into rotational force.

The present invention relates to a moving device that swings the body and uses this reciprocating energy as a propulsive force. By using the reciprocating inertia force, a propulsive force can be obtained with minimal force such as leg force and arm force. It is.

Conventional mobile devices such as automobiles have been propelled mainly by the power of hands and feet. It would be convenient if there was a moving tool that propelled using the body's amplitude moment of inertia using the whole body.

As a similar moving tool, there is a bicycle that obtains a propulsive force by swinging a handle as shown in Patent Document 1, but a strong arm force is required to move the handle.

The present invention has a simple structure and does not rely on hand force or foot force as in the prior art, but realizes a moving tool by human power that swings and propels the entire body.

A riding part on which a person rides is coupled to a wheel frame that supports the wheels by a single support shaft.
And the person who got in this boarding part shakes a boarding part, and swings like a pendulum about this support shaft.
The reciprocating kinetic energy of this shaking is rotated by a reciprocating rotation conversion mechanism and propelled by rotating the wheel.

Unlike bicycles that use legs, the body swings and travels, so it feels different from the conventional ride, has fun as a playground equipment, and is the best mobility tool for powerless elderly people.
Of course, it can be used universally as a human-powered vehicle comparable to a bicycle.

In addition, considering the size of the saddle and the arrangement of the wheels so that people with disabilities can use it, there is a possibility that it can be used as a mobility tool for the handicapped person more easily than a wheelchair.
