Abstract

PROBLEM TO BE SOLVED: To restrain a wheelbarrow from overturning in the longitudinal direction in practicing the wheelbarrow so as to enable safe practice by fitting an arm extended in the longitudinal direction to the frame main body of the wheelbarrow to wrap the tire of the wheelbarrow, and supporting an auxiliary wheel to the lower end of each arm. SOLUTION: A practice tool fitted to a part of the frame main body 5 of a wheelbarrow has a metal fitting 2 formed by providing an iron plate having a bolt hole on both end parts of a pipe two-split member, and the metal fitting 2 is disposed in the outer periphery of the frame main body 5 and temporarily fixed by fastening a bolt-nut 4. A pair of front and rear arms 1, the upper end of which is fixed to the fitting 2, with the auxiliary wheel 3 supported on the lower end, are adjusted in its fitting position so that both of the front and rear auxiliary wheels 1 are separated from the ground about 2 cm, and then the bolt-nut 4 is finally fastened. The arm 1 is formed by an iron-made pipe having satisfactory strength and formed to be freely expanded and contracted in the longitudinal direction at need.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unicycle training device in which auxiliary wheels are attached before and after wheels of a unicycle.

[0002]

2. Description of the Related Art Conventionally, a unicycle has only one wheel, so it is difficult to balance it, it is difficult to practice alone, and a considerable amount of hit such as hitting the head or waist by suddenly falling back and forth. Despite the danger, nonetheless, there was no safe practice equipment to use on the unicycle itself. For this reason, the practice of the unicycle at the elementary stage has been carried out by having another person support or using a handrail for unicycle practice.

[0003]

[Problems to be Solved by the Invention] Since there is no safe and reliable training equipment to be attached to the unicycle itself, the practice of riding the unicycle is carried out by a parent or the like, or a unicycle installed in a school playground or the like. We use handrails for practice. If you have such a good environment, you can reach the point where you can manage it, but if not,
There was a problem that progress was difficult. In addition, if you practice excessively on the road without supporting people or handrails, your body will not be able to respond immediately to the forward and backward movement of the unicycle, and in some cases it may lead to fractures of the head and waist. The danger was great.

[0004] In addition, schools and the like often do not have appropriate training facilities, and it is extremely difficult for a child with a delayed development of motor nerves or an adult with a rigid body to improve a unicycle. For this reason, in recent years, as the health orientation of adults has become stronger, there are many wishes such as parents who want to enjoy a unicycle with a child for the purpose of maintaining and improving health and contact between parents and children, but they have to give up, etc. There was a problem.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an arm extending back and forth so as to enclose a unicycle tire 8 from a unicycle frame body 5 as shown in FIG. An auxiliary wheel 3 and the like are attached to the tip of the vehicle. In this case, the auxiliary wheels may be casters of a type that rolls at an angle in any direction or a bicycle auxiliary wheel for training. The arm 1 can also be attached so that the wheel is sandwiched between the bases of the left and right pedals of the axle of the unicycle as shown in FIG.

In the case of a unicycle, unlike a bicycle, the sideways movement can be made agile, so that little consideration is needed for falling down. However, if necessary, the ends of the front and rear arms are branched to form two auxiliary wheels. You may attach individually.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. In FIG. 1, when the training device according to the present invention is mounted on the frame body 5 of the unicycle, the distance between the auxiliary wheel 3 and the ground can be adjusted by moving the mounting bracket 2 welded to the tip of the arm 1 up and down. I have to. However, by adjusting the lower end of the auxiliary wheel 3 to be several centimeters away from the ground surface with the weight on the unicycle, the auxiliary wheel 3 floats in front and back when running in good balance. It does not work, but once the balance is lost back and forth, the front or rear auxiliary wheel comes into contact with the ground and will be supported by the two tires of the unicycle and the two grounding points of the front and rear auxiliary wheels, so it will be further back and forth It is designed not to fall down. For this reason, without having to be supported by a person or requiring a handrail, using the present invention, even if a beginner etc. may lose a great deal of balance while practicing a unicycle, It won't fall, and if you calm down your feet, you won't fall.

In FIG. 1, the mounting bracket 2 is welded to both sides of an iron plate provided with holes for bolt tightening in a shape obtained by splitting a pipe into two. This is welded to the front and rear ends of the arms 1 and firmly tightened with four bolts and nuts 4 to complete the mounting. The arm 1 is a pipe made of iron or the like having sufficient strength. In FIG. 1, the arm 1 is bent so as to be concentric with the tire of the unicycle. However, the arm 1 is not necessarily required to have this shape. The shape may be such that it becomes two sides of an isosceles triangle. . If necessary, the distance between the front and rear auxiliary wheels may be changed so that the arm 1 can be extended and retracted back and forth.

The assembling method and the method of use will be briefly described. The mounting bracket 2 is temporarily fixed to the frame body 5 of the unicycle with bolts and nuts 4. In this case, the front and rear arms 1 need to be mounted on the center of the tire of the unicycle with good balance. Next, in a state in which the tires are compressed on a unicycle, both the front and rear auxiliary wheels 1 are adjusted to be separated from the ground surface by about 2 cm, and then the bolts and nuts 4 are fully tightened and securely fixed. . As for the separation, an appropriate separation is adopted in consideration of the condition of the road surface and the state of progress.

The present device is used by a beginner to practice a unicycle, and the distance between the ground and the auxiliary wheels is widened according to the stage of improvement, and the balance is learned by the body, and immediately after the self-confidence is attained. Remove it.

FIG. 2 shows the mounting position of the arm 1 at the base of the left and right pedals on the axle of the wheel of the unicycle.
The arm 1 is shaped like a steel band and has a shape that sandwiches the wheel. The other points are the same as the example of FIG.

[0012]

Since the present invention is configured as described above, the present invention has the following effects because it can be prevented from falling back and forth.

It is possible to prevent a disaster caused by banging the head or waist.

Since the fear is eliminated and no handrail for training or a supporting person is required, the user can practice freely and at any time anywhere without hesitation.

Since the improvement of the unicycle can be easily performed, the unicycle can be further popularized as an easy sport for people and can contribute to the promotion of health.

[0016] Parents and children, brothers and sisters, friends groups, etc. can enjoy together, strengthening their ties and contributing to the development of a healthy society.
