Abstract

PURPOSE: A foot-driven kick board and a method for using the force of a foot as a power source are provided to transmit power while a user stands upright and to make a user conveniently carry a kick board by reducing weight. CONSTITUTION: A lever is attached with a pedal(7). A user steps on the pedal with one foot while supporting the body on a kick board with another foot. A drive mechanism rotates a rotor by converting the upward and downward motion of the lever to rotational motion. The rotational force of the rotor is transmitted to a rear wheel(6) by a transmitting unit. With the rotational force, the rear wheel is rotated. Thus, the user drives the kick board in the upright stance.

Description

Foot-powered quick board driven by the force of the foot and a method therefor {Foot powered quick-board and method}

The present invention relates to a power quick board, which is small and light, which is convenient to move and to move like a bicycle by driving wheels with the power of a foot, and overcomes the disadvantage that a conventional quick board cannot use the power of a user's foot in a riding position. He stood up and stepped on his foot pedal to transmit power.

The present invention is equipped with a drive mechanism for converting the up and down motion of the foot into a rotational movement to the conventional quick board, so that the user can ride on the quick board by stepping on the footboard in the quick board, so that the transmission can be attached to the transmission like a normal bicycle.

By overcoming the difficulty of the user's upright due to the first rotation of the existing bicycle, the user can stably ride by standing on the footrest at an angle of about 45 degrees. One foot is on the board, and the other foot is preferably stepped on the pedals, and it is safe to step on both feet. The present invention has the advantage of being able to stand stably because one foot on the board and the other foot to step on the pedal up and down. The present invention has the advantage that only the front pedal comes out as shown in Figure 3 and the board is stably fixed and the rear wheel portion can bounce when the rear wheel is large. In the present invention, the number of wheels may be two, three, four.

The size of the rear wheels can be made larger in consideration of speed, but they are designed for portability and design, and designed to be below the center of gravity for stability. The pedal stepping angle (up and down distance) can be adjusted according to the user's size, and it is designed considering the stepping force, speed, and speed of the quick board. The driving mechanism is also cited in the prior art so as to generate the most efficient driving.

You can apply the drive mechanism directly to the rear wheels without a chain, and turn the rear wheels directly, but it's not as good as shifting into a chain because the wheels need to be quite large to speed up. However, this configuration is irrelevant.

When the size of the rear wheel is increased, the rear wheel shaft is higher than the board, and when the user stands up, the plate may be designed to be lowered to the floor so as to lower the center of gravity. In this way, when the user stands and rides the present invention to facilitate the centering.

The rear wheel axle means the center of rotation of the rear wheel, and both the rear wheel and the gear are firmly fixed to the plate.

Hereinafter, a configuration in which the pedal portion and the crank portion are integrated is referred to as a driving portion. In the pedal unit, the lever 8 and the lever arm 10 are fixed at an angle with respect to the lever axis 9. The angle is determined in relation to the length of the crank 12 and the position of the crankshaft 13 as the length to rotate the wheel 6 by stepping on the pedal (7). In addition, the length of the lever 8, the lever arm 10 and the crank 12 and the position of the crankshaft 13 are the force and stepping on the pedal 7 in the range that can rotate the wheel (6) And the angle formed by the board 4 is determined.

The crankshaft 13 is attached to the rotating body and the rotating body (not shown) is attached to the wheel 6 to rotate the wheels. Therefore, in Figure 1, the rotor is attached to the side of the wheel.

The driving principle of this driving mechanism is that, as shown in Fig. 2, when the user steps on the pedal 7, the wheel 6 rotates in the same order as in Figs. This principle is similar to the driving principle of a combustion engine engine, and is a known principle. That is, the same principle as replacing the explosive power with human feet in the combustion engine engine.
