Description

A three-wheeled boarding apparatus capable of tilting,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-wheeled boarding machine, and more particularly, to a three-wheeled boarding machine that allows a user to step on a footrest portion in a line state to drive a driving wheel and tilt the predetermined portion during cornering.

In general, a boarding mechanism refers to a mechanism for moving a passenger by moving or carrying various articles, and may include a bicycle, a board, a scooter, and the like. Such a boarding device is configured to have a driving wheel, follower wheels, and a boarding area, and can be classified into a three-wheel type or a reverse-type wheel type.

A tricting or tilting device is required to tilt the boarding instrument in order to compensate for the centrifugal force. Therefore, much research has been done on tilting of such a boarding instrument.

However, if a standing-riding three-wheeled boarding machine releases its foot from a pedal for driving, the weight of the occupant moves to the opposite pedal, and at the same time the body of the boarding instrument tilts to that side, . In this case, a support member for supporting the load of the pedal is required. When the body part is inclined to correspond to the centrifugal force during cornering, a part of the pedal and the support member are rubbed at a predetermined interval, have.

The technology to be a background of the present invention is disclosed in Korean Patent Registration No. 10-1581635 (registered date: 2015.12.23).

SUMMARY OF THE INVENTION It is an object of the present invention to provide a three-wheeled boarding machine in which a weight of a passenger is not tilted by the weight of a passenger even when the weight of a passenger is shifted to one side have.
Another object of the present invention is to reduce the compressive stress per unit area by increasing the contact area between the pedal and the supporting member for supporting the load of the occupant when the pedal is stepped on both feet, The pedal and the support member can be reduced in friction force to a minimum, thereby reducing the wear of the pedal and the support member even when using the pedal for a long period of time.
