1 is a view showing the structure of a multi-use bicycle according to an embodiment of the present invention, and
2 is a view showing a coupling structure of the coupling member in FIG.

Hereinafter, with reference to the drawings will be described the present invention in more detail. It should be noted that the same elements in the figures are represented by the same numerals wherever possible. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a view showing the structure of a multi-use bicycle according to an embodiment of the present invention. Referring to FIG. 1, in a multi-use bicycle according to an exemplary embodiment of the present invention, a unicycle 200 is coupled to one side of a two-wheeled bicycle 100 through a coupling member 150.

That is, by combining the saddle support 210 of the unicycle 200 through the saddle support 110 and the coupling member 150 of the two-wheeled bicycle 100, the multi-use bicycle in the present invention can be at least two people boarding It is a bicycle.

In the multi-person bicycle in the present invention, the two riders in the state in which the unicycle 200 and the two-wheeled bicycle 100 are coupled to supply power required for the forward movement through the pedals provided in each bicycle.

However, in the forward movement, since the power transmitted through the two-wheeled bicycle 100 is greater than the power transmitted through the unicycle 200, the two-wheeled bicycle 100 is towing the multi-use bicycle in the present invention It will be a power source.

Therefore, when riding with a man and a woman, in general, a man of good strength rides on a two-wheeled bicycle 100, and a woman rides on a unicycle 200 would be desirable.

In addition, since the direction change through the handle attached to the two wheel bicycle 100 as the main power source will be easier than the direction change through the handle attached to the unicycle 200, through the handle attached to the two wheel bicycle 100 The driving direction of the multiplayer bicycle in the present invention will mainly be determined.

On the other hand, in general, when the traffic of people, bicycles, cars, etc., in order to secure the convenience and stability of driving during the passage, in principle, as shown in Figure 1, the unicycle 200 is a two-wheeled bicycle 100 It would be desirable to be coupled to the right side of.

That is, when the unicycle 200 is coupled to the right side of the two-wheeled bicycle 100, the occupant who rides the unicycle 200 can be protected from the bicycle coming from the opposite side.

In addition, as shown in Figure 1, the coupling member 150 is combined in the position of 5 ~ 10cm of the rear of each saddle support (110,210) in the form of 'c' does not interfere with the bike pedal movement of the two occupants at all. .

In addition, in the practice of the present invention, the unicycle 200 and the two-wheeled bicycle 100 will be preferable not to cause a problem in driving by combining at a horizontal distance of about 40 ~ 50cm.
