Description
The present invention relates to a bicycle using a directional castor capable of traveling only by the use of both arms.
Generally, a bicycle is a device designed to allow a person to sit on a saddle, grab the handle with both hands and turn the wheel by the force of the two legs.
To this end, the bicycle includes a frame, wheels provided on the front and rear sides of the frame, a handle capable of controlling the traveling direction, and a saddle on which the occupant can ride. Further, the bicycle has a saddle on which a person can sit, a pedal provided on the bottom of the saddle, and a chain connecting the pedal and the rear wheel.
When a person steps on a pedal using a pair of feet, the chain connected to the pedal drives the rear wheel so that the bicycle can advance. The handle allows control of the direction of the ongoing bike, and the brake attached to the handle allows it to stop while the bike is running.
Such a general bicycle can generate a driving force only by a pedal, and thus can not be used for patients or disabled persons who can not freely use their feet.
Registration Utility Model No. 20-0427359 discloses a bicycle having a directional castor that can be advanced using both arms to solve this problem.
