Description

In the present invention, when folding a conventional folding bicycle breaker (Japanese Patent Application No. 2 0 0 5 -2 5 1 5 8 1),
The idea of removing all other extraneous items after aligning both wheels is further 1
An evolutionary version of the folding bicycle break that can be carried using both wheels even after folding, with two steps.
Is related to the technology.

When folding the conventional folding bicycle breaker (Japanese Patent Application No. 2 0 0 5 -2 5 1 5 8 1), the idea of eliminating other extraneous items after aligning both wheels is further 2 steps.
Consider an evolutionary version of the foldable bicycle break that can be carried using both wheels, even after folding.
Japanese Patent Application No.1 1-3 3 3 2 0 4 Patent Application 2 0 0 5 -2 5 1 5 8 1

It is in the range of the conventional folding bicycle reform (Japanese Patent Application No. 2 0 0 5 -2 5 1 5 8 1). Is it not included?
Folding bicycle break (Japanese Patent Application No. 2 0 0 5 -2 5 1 5 8 1) can be carried more easily by rolling from the baggage that is carried by hand by rotating both wheels, even after folding. However, in the case of a normal bicycle, particularly when the bicycle is lowered later, the ease of rotation differs between the front wheels and the rear wheels connected to the front gear.
In the case of a motorcycle, it has a neutral gear, so there is no problem, but in the case of a bicycle,
The first problem is that, especially when going down later, the rolling resistance of the two wheels will be different, so it will not roll smoothly.
Also, even after folding the bicycle (Japanese Patent Application No. 2 0 0 5 -2 5 1 5 8 1), by rotating both wheels, it is easier to roll from the baggage that you carry with your hand. In order to be able to carry it, there is a reason that a new wheel is provided in order to make it easier to carry, from 2 wheels to 3 or 4 wheels, but it is rare to carry by pushing and pulling such a long distance. From the idea of brazing, the cost of wheel and steering wheel, that is, the meshing of both shafts (

Aimed to reduce the cost of parts.
When using a motorcycle bag (I think it is necessary especially when using a train etc.)
It is proposed that the middle part of the two wheels in contact with the ground of the motorcycle bag and the new wheel be closed.

A foldable two-wheeled vehicle that is easy to move by the wheel (6)
1 1) Although it is in, I thought about attaching a handle (15) to make a flight when actually carrying it.

The new wheel (6) of the folding motorcycle is designed to be easy to operate with your foot (6)
1 3)
A foldable two-wheeled vehicle provided with a mudguard-like brake (8).
A brake (8) is always required for moving objects, especially in the case of a foldable two-wheeled vehicle, because the person is away from the saddle (4), that is, the driver's seat.
8) Considering a mudguard-like brake (8) with a foot allowance (13) to make it easier to apply with a foot and easier to operate with feet.

One of the two folding lines of the folding motorcycle is to prepare another cylinder (5) for inserting the same handle (3) as the normal one on the side of the frame leading to the rear wheel (2). A folding motorcycle.
Folding bicycle break (Japanese Patent Application No. 2 0 0 5 -2 5 1 5 8 1) can be carried more easily by rolling from the baggage that is carried by hand by rotating both wheels, even after folding. However, if you use a normal bicycle here, especially if you go backwards,
1) and
The rear wheel (2) connected to the front gear is different in ease of rotation.
And the problem of rolling resistance of both wheels when pulling or pushing is basically a free kite, even when moving forward, but it can be ignored in the normal bicycle state, In particular, when both wheels are rotated side by side, it cannot be said that there is no influence from the slight difference.
In this state, even if you pull or push the center point of the front in the direction you want to go, especially when going backward, the rolling resistance of both wheels will be different, so it will not roll smoothly, so it will be more resistant. Move the fulcrum and center of gravity to the rear wheel (2) side with the larger
The idea is to pull or push the key mainly.

When connecting the bicycle (motorcycle) to the front gear of the rear wheel (2), the neutral gear (
Folding bicycle (two-wheeled vehicle) characterized by adding 2 0)
.
For the same reason as above, it will not be able to roll smoothly, especially afterwards, so connect the front gear of the rear wheel (2) with a neutral gear and let both wheels roll smoothly. This is the idea.
Neutral gear means, for example, that the forward gear is a rear wheel (2
)
The sixth gear can be anywhere, but it is usually the most commonly used gear.
Next to the speed, for example, as a sixth gear (= neutral)
Unlike the other five gears, the second gear (= neutral) is the same as the rear transmission (2 1) and the rear wheels (
2) is attached to the frame, that is, it exists as a separate rotary body from the rear wheel (2).
2)
Does not share any rotation and does not regulate their movements.
Therefore, if the bicycle gear is set to neutral, the folded rear wheel (2) of the foldable bicycle can be rolled back and forth as well as the front wheel (1) without being restricted by anyone. I can do it.
