Abstract

PURPOSE: A kickboard type bike drive gear is provided to easily drive a bike by enabling a user to step a pedal backward. CONSTITUTION: A kickboard type bike drive gear comprises a bike pedal(16) and a crank arm(13). The bike pedal and the crank arm are integrated with a pinion gear(14). A locking protrusion is formed in the inner side of the pinion gear and fixes one end of a spring to control the rotation range of the crank arm. A rotation center shaft is fixed to a frame(5). A planetary gear(14) transfers torque to a sun gear(22) fixed to the rotation center shaft through a bearing.

Description

Kickboard type bicycle driving device {KICKBOARD TYPE BIKE RUNNING GEAR}

The present invention relates to a kickboard-type bicycle driving device which is made by driving the rear wheel portion as a method for making a driving device on a kickboard-type bicycle and going forward while stepping on a pedal back in a direction opposite to a conventional bicycle.

The present invention is to form a driving device on the rear wheel of the existing kickboard and to drive by using a pedal of the bicycle, unlike a conventional bicycle, one foot on the footboard while using the other pedal and the other foot to step backward The bike forward.

Using a larger wheel diameter than a conventional kickboard, the driver makes a drive on the rear wheel, puts one foot on the kickboard footboard, and the other foot pedals the rear wheel to drive the bicycle forward.

The bicycle pedal 16 and the crank arm 13 form a groove 15a by attaching a locking jaw 15 to the inside of the pinion gear 14 while being integral with the large pinion gear 14, which is a planetary gear. 11) secures one end 11b and attaches a part 15 having a locking jaw function to control the rotation range of the crank arm 13, and the crank arm 13 is driven by the elastic force of the spring 11. After it is made, it is returned to its original position, and the rotation center shaft 9 is fixed to the frame 5, and the large diameter pinion gear 14, which is a planetary gear, is fixed to the rotation center shaft 9 by the bearing 12, so that the center of the rear wheel is It transmits rotational force to the small-diameter pinion gear 22, which is a sun gear fixed to the shaft 24, in which the one-way gear 23 is inserted and fixed to the inside of the small-pinion gear 22a, and the pedal is only on one side of the bicycle. (16) make one foot on the board plate (2) and the other Roneun means to get out the bike stepped on the pedal (16) back and forth;

It is used as a driving device for riding equipment such as kickboards and as a driving device for bicycles.

Figure 3 is a perspective view showing the movement range of the pedal and the rotation direction of the pedal and the order in which energy is transmitted
Figure 4 is a perspective view of the state using a bicycle made of the present invention

The present invention is driven by attaching a bicycle pedal to the kickboard in order to enjoy the existing kickboard in a little fun and dynamic movements, and unlike the conventional bicycle, the pedal of the bicycle by stepping on the pedal while using one pedal It's about the technology that drives the bike forward.

1 to 4 in the frame (3) to make and secure the footrest (2) attached to the frame and the QR lever (4) for attaching and detaching the saddle or carrier of the bicycle and the crank arm (13) to the frame (5) One end 11b of the spring 11 is fixed to the inside of the pinion gear 14 (inside the crank arm rear view) to fix the rotational central shaft 9 formed by the integral pinion gear 14 having a large diameter, which is a planetary gear. There is a groove 15a of the locking jaw 15 that can fix the locking jaw 15 is closed to the frame 5 to adjust the movement range of the crank arm 13. Inside the pinion gear 14 there are bearing housings 14a and 14b, and bearings 12 are inserted on both sides of the pinion gear 14 to move the pinion gear 14 fixed to the rotational central shaft 9 with nuts 17 and 18. The spring 11 is inserted outside the rotation center shaft 9 of the pinion gear 14 so that one end 11a of the spring is fixed to the frame 5 and the other end 11b to the locking jaw 15a. After 13 is moved, the spring 11 returns to its original position, and the pedal 16 is fixed to the crank arm 13a.

As the sun gear, the one-way gear 23 is fixed to the inside of the pinion gear having a small diameter. The nut 22a of the left screw is assembled inside the pinion gear, and the bolt 23a of the left screw is made outside the one-way gear. At the same time to prevent loosening and to the inner gear of the one-way gear 23 to make a nut (23b) in the right direction to be fixed to the central axis (24a) of the wheel. The bearing 19 fixed to the central axis 24 of the wheel is inserted into the bearing housings 7 and 7a to fix the bearing housings 7 and 7a with the bolt nut 8 to secure the rear wheel 25 of the bicycle. It is fixed to the frame.

In the present invention, the energy transmission sequence is described in FIG. 3. When the pedal 16 rotates counterclockwise from the A position to the B position, the large pinion gear 14 rotates in the counterclockwise direction C, and the diameter is increased. The small pinion gear 22 is rotated in the clockwise direction D to be transmitted to the one-way gear 23 fixed together with the small diameter pinion gear central axis and transmitted to the wheel 25.

Figure 4 shows the figure that shows the position of the body and the position of the foot while driving the bicycle, one foot on the board plate, and the other foot to step forward by the pedal and use the two feet on the footboard like a kickboard.
