Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle which is improved so that it can hang down on a railway line stretched in the air.

[0002]

2. Description of the Related Art As a vehicle moving in the air, a pulley with a string attached to a rope stretched in the air between two inclined points is attached to a rope, which is seen in a playground equipment such as field athletics. There was something to do. The pulley is arranged in the frame body, the rope is also passed through the frame body, and the frame body is provided with a hanging string.

[0003]

According to a vehicle using a rope connecting two inclined points, the rope passes through the frame body, so that the vehicle can only move between two points having a certain distance.
This is because if the rope was supported halfway, it would not be possible for the pulley to pass through, so it was only possible to move a short distance. The amount of rope that supports only both ends depends on the rider's weight difference at the center. In other words, the heavier the person, the closer to the ground, so the height of both ends supporting the rope had to be increased. Therefore, the smaller the child,
It was dangerous because the starting point and the ending point were higher than the ground level.
When the amount of sagging in the middle of the rope becomes large, the pulley moves upward from the middle, so there is a big drawback that it is boring because it can not move to the end point and it can not move by inertia alone. The present invention is
The present invention has been made to solve such a problem, and an object of the present invention is to provide a bicycle that can be moved along a track by a rider's operation so as to walk in the air.

[0005]

In order to solve the above problems, the present invention has the following configuration. A first gear for rotating the wheels is attached to an axle of wheels arranged in parallel and moving on the track, and a transmission having a second gear for rotating the wheels is suspended from the axle. I placed it. In addition, an operating device provided with an operating rod with a pedal is attached to this transmission device.

[0006]

[Function] The operating rods are moved up and down by placing the wheels arranged in parallel on the track and stepping on the pedals. The vertical movement of the operating rod causes the second gear forming the transmission device to rotate, and this rotation is transmitted to the first gear to rotate the wheels. Since the wheels are placed on the track, they move along the track.
