JP2004148937A - Auxiliary wheel gear for child bicycle practice having function of raising tilted bicycle using eccentric wheel - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide an auxiliary wheel gear for child bicycle practice that improves practice effect as the auxiliary wheel gear that does not always contact the ground during while tilted, and can continue the practice by raising the tilted bicycle. <P>SOLUTION: An eccentric wheel 1 of which an axle 2 is shifted from the center is mounted to the auxiliary wheel gear. When the bicycle tilts and the wheel of the auxiliary wheel gear contacts with the ground, the diameter of the eccentric wheel increases with rotation, and the bicycle is raised accordingly. The wheel 2 is not perfectly circular but is deformed in an asymmetric shape with respect to the center, and does not always contact with the ground when it tilts. This configuration solves a problem wherein a perfectly circular wheel, in the auxiliary wheel gear for the bicycle practice by the child, always contacts with the ground when it tilts to spoil bicycle practice. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
Auxiliary vehicle for children's bicycle training. This is an auxiliary vehicle that uses an eccentric wheel so that it does not always contact the ground when tilted, and has the function of raising a tilted bicycle to enhance the bicycle training effect.
[0002]
[Prior art]
As a method of practicing a child's bicycle, there is a method in which an adult keeps a child's bicycle by hand while running, but if it is always secured by hand, it is not necessary to practice and sometimes let go of it.
[0003]
Auxiliary vehicles are generally used on the left and right sides of the bicycle for practicing bicycles for children. However, an auxiliary vehicle with perfect circular wheels will always contact the ground when tilted, and during that time it will not be a bicycle practice.
[0004]
[Problems to be solved by the invention]
Enhance the effectiveness of children's bicycle practice.
[0005]
An auxiliary vehicle that does not always contact the ground when tilted.
[0006]
An auxiliary vehicle that can wake up a bicycle and continue practicing.
[0007]
[Means for Solving the Problems]
An auxiliary vehicle whose wheels do not always contact the ground when the bicycle is tilted can be realized by decentering the shaft of the wheels or deforming the wheels to a non-circular shape.
[0008]
If the wheels are eccentric, the wheels will not always contact the ground when tilted.
[0009]
If you use eccentric wheels, you can raise your bike and continue your practice.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
This will be described in detail with reference to the drawings.
In FIGS. 1 and 2, the eccentric wheels 1 and 21 are obtained by shifting the axles 2 and 22 from the centers 3 and 23 of the wheels and have the shortest diameters 4 and 24 of the wheels and the longest diameters 5 and 25 of the wheels.
[0011]
The wheel weights 7, 27 are provided so that the shortest diameters 4, 24 of the wheels are on the lower side so that the eccentric wheels 1, 21 of the auxiliary vehicle do not touch the ground 8, 28 when the bicycle is running upright. is there.
[0012]
Auxiliary vehicles that use eccentric wheels are practiced on the left and right sides of the bicycle.
[0013]
When the bicycle leans and the shortest diameter 4, 24 of the auxiliary vehicle touches the ground 8, 28, the diameter of the wheel increases with the rotation, and the bicycle is raised as the wheel rotates, and the longest diameter of the wheel 5, like the right wheel in FIG. Wake up until 25 is down.
[0014]
The wake-up by the bicycle assisted vehicle is discreet so as not to get too woken up, leaving room for practice by operating the steering wheel on its own.
[0015]
When practicing a bicycle with an auxiliary vehicle that uses eccentric wheels, it can wake up even if you lean, you can continue practicing and enhance the practice effect.
[0016]
As shown in FIG. 3A, an auxiliary vehicle having wheels whose wheels are decentered by asymmetrically deforming the tires of the wheels with respect to the center can also be used.
[0017]
FIGS. 3B and 32 show that the rotation angle of the wheel changes from the shortest diameter to the longest diameter at a wheel rotation angle of 270 degrees, and the bicycle can be slowly lifted, but the left and right wheels cannot be shared.
[0018]
FIG. 3 (c) shows the wheel deformed into an elliptical shape 33, a triangular shape (omitted), a square shape (omitted), etc., and the same effect can be obtained, but it is inferior in terms of a smooth raising function.
