Abstract

PURPOSE: To provide a variable accessary toy for bicycle whose shape is changed to extend or contract depending on the running speed, by making a spiral cord function its elasticity by the centrifugal force by the rotation of the wheels in the running condition. CONSTITUTION: An installing terminal 2 to fix to the spoke of a bicycle is provided to one side end of a spiral cord 1 cut to pieces at a specific length, while a weight 3 is provided to the other side end, and the installing terminal 2 is assembled to the spoke crossing part 7 of the bicycle.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable accessory that can be enjoyed by mounting it on a bicycle.

[0002]

2. Description of the Related Art Conventional bicycle accessories are intended for practical purposes, and there has been nothing that stimulates the enjoyment and playfulness of riding a bicycle, such as movement and change in shape.

[0003]

[Problems to be solved by the invention]

I. Add fun using the function of moving a bicycle. B. The function of expanding and contracting the shape is added in conjunction with the rotation of the wheels during running.

[0004]

A spiral cord (1) cut into a specific length is provided with a mounting terminal (2) at one end for fixing to a spoke of a bicycle, and a weight (3) is provided at the other end. , Attach the mounting terminal (2) to the intersection (7) of the spokes of the bicycle.

[0005]

[Operation] When using the present invention, when the bicycle is stopped, the spiral cords (1) attached to the spokes are contracted by the contracting force, and gather in the central portion where the axle (5) is present, and as shown in FIG. Form a small circle. When a bicycle is run, centrifugal force is generated due to the rotation of the wheels, resulting in a spiral cord (1)
Since the weight (3) provided on the wheel moves in the direction of the wheel rim (8), the mounting terminal (2) is attached to the spoke intersection (7).
The main body of the spiral cord (1) fixed by is expanded and the outer ring is gradually expanded. When the rotational speed of the wheel increases due to the high speed running, the spiral cord (1) extends until it comes into contact with the inner side of the rim (8), and the wheel is maximized in appearance as shown in FIG. When the traveling speed is slowed down, the rotation of the wheels becomes slower and the centrifugal force generated becomes smaller, so that the weight (3) returns to the direction of the axle (5) and the spiral cord (1) contracts. It gets smaller and smaller. By repeating this, the loop of the spiral cord in the wheel expands and shrinks, and it looks as if the flower blooms and shrinks.

EXAMPLES Examples of the present invention will be described below. To install on a spoke of a wheel, which has a terminal (2) for fixing to a spoke of a bicycle at one end of a spiral cord (1) cut into a specific length, and a weight (3) at the other end. And, a bicycle accessory toy whose shape expands and contracts according to the rotation of the wheels. (A) Attachment terminal for cutting the spiral cord (1) of the same shape as that normally used in telephones into a specified length and fixing it to the spoke intersection (7) of the bicycle at the cut end. (2) is provided. (B) A weight (3) is provided at the other end of the spiral cord (1) provided with the attachment terminal (2). The present invention has the above configuration. When the present invention is used, the spokes (6) of the bicycle are fitted into the inside of the shredded end (4) of the spiral cord (1) as shown in FIG. 2, and the spiral cord (1) is rotated in the arrow direction, The spokes (6) are completely housed in a spiral tube shape as shown in FIG. Next, the ring-shaped mounting terminals (2) that can be opened and closed are assembled and fixed to the spoke intersections (7) as shown in FIG. The present invention is characterized by skillfully applying the elasticity of the spiral cord and the centrifugal force generated by the rotation of the bicycle wheel. When the color of the rubber material or the plastic material that covers the outer surface of the spiral cord (1) is colored as vividly as possible, the fun is stimulated. It is also possible to apply reflective fluorescent paint as a safety sign when driving at night.

[0007]

By using the present invention, it is possible to stimulate the playfulness of children and young people when riding a bicycle and add new fun to cycling. In addition, the application of reflective fluorescent paint has the effect of contributing to traffic safety measures.
