Definitions

• the present invention relates to a foot bike, which can be worn by two feet like a pair of shoes for walking or running as a means of movement and exercise.
• the present invention relates to a foot bike which provides a means of movement and exercise tool, featuring unidirectional bearings mounted on a shaft of wheel supporters which widen with an inclination when weight is loaded on the foot plate and close up when the weight is unloaded. Moreover, the unidirectional bearings generate the rotating displacement by the widening wheel supporters and increase the rotation by the power transfer mechanism, thereby the increased rotation being transmitted to the wheels.
• Korean Laid-Open Patent Publication No. 2003-0060448 relates to a means of movement integrated with a steering device on which a person can ride by holding the steering device, moving two foot plates up and down to generate rotating force of the wheels, and controlling its moving direction by the steering device.
• the present invention does not have much difference with traditional bicycle except generating the rotating power of wheels by up and down movement of two feet instead of rotating pedals with two feet, and has the shortcoming of complex mechanism because it has to change up and down linear movement to the rotating force of wheels.
• the first problem of the prior invention is that it is impossible to stand on the foot plates due to the structure thereof.
• the top of two wheel supporters is supported by a shaft and the bottom by a tension spring, so the two wheel supporters widen when you step on them; but because you cannot keep balance of your feet you cannot help but fall down even before moving forward.
• the principle of walking aid which is the main idea of this prior invention is to use unidirectional bearings on the shafts of front and rear wheels so that when you press the foot plates, the wheel supporters widen, the rear shaft stays where it is (without moving backward), and the front shaft moves forward; when you remove your feet, the rear shaft follows without the front supporting shaft of the wheel supporter moving backward. Consequently, this prior invention moves forward only and because of this people may think that it will assist walking. In fact, however, the invention moves forward only slightly as much as the widening of the wheel supporters, but cannot move a desirable distance with the driving power of wheels.
• the U.S. patent no. 684,260 which was patented in 1901 is another traditional technique to rotate wheels by body weight. The foot plates are supported by springs, pressed by weight, and return to original position when feet are removed. When the foot plates are pressed by weight, the latch pushes the chain downward and the interlocked rear wheels are rotated.
• the present invention discloses various types of movement means but is focused on providing a movement mean or exercise tool, which is not large, easy to carry, and able to naturally move while walking.
• Another object of the present invention is to provide a foot bike which allows safe exercise by maintaining the balance of foot plates, thus increasing stability of posture, even when the riding person bends forward or backward, through the interlocking of the two supporters for front and rear wheels.
• the present invention which generates rotating force and moves forward when the person wearing it walks, comprises a foot plate on which a means of fixing the person's feet is mounted (12-1); a shaft supporting plate formed vertically at the bottom of the foot plate; a front supporting shaft of the wheel supporter and a rear supporting shaft of the wheel supporter installed at the front and back of the shaft supporting plate; a front wheel supporter and a rear wheel supporter having the wheels installed at the bottom centering around the supporting shafts; engaging means formed at the top of the front wheel supporter and the rear wheel supporter so as to maintain the balance of the foot plate when the front wheel supporter and the rear wheel supporter widen and close up; a unidirectional bearing mounted on a shaft of the front and rear wheel supporters which widen with an inclination when weight is loaded on the foot plate and close up when the weight is unloaded, and fixed with the wheel supporters at the outside of the bearing, so that the rotary displacement generates the rotating power in one direction by the widening wheel supporters; a speed increasing means to
