In addition, even if all the reference numbers are not described in all the drawings, the same objects are referred to by the same reference numerals. 1 shows the drive mechanism of the present application. The drive mechanism comprises a pedal including a pedal 7, a lever 8, a lever axle 9, a lever arm 10, a lever arm 11, a crank 12 and a crankshaft 13. It is configured to include a crank portion and the wheel (6) and the lever shaft (9) is fixed to the board (4) to be rotated up and down. 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 may be 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 and may be determined in the range of 0 to 360 degrees. have. At 0 degrees, 8 and 10 can be one. It is the same principle as FIG. 23, and it turns out that 9 is located in front of a rotating body. 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 this rotating body (not shown) is attached to the wheel 6 to rotate the wheel. Therefore, in Figure 1, the rotating body 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.

Figure 3 is a block diagram of the actuation kickboard equipped with the drive mechanism of the present application. The actuation kickboard is comprised of a kickboard part comprising a handle 1, a handle shaft 2, a wheel 3, a board 4, a cover 5, a drive mechanism and a drive part and a wheel 6. The kickboard unit is configured to allow the user to stand up and drive in a standing posture, and the center of gravity of the user is preferably configured to be as close to the ground as possible. Here, as shown in FIG. 1, the drive mechanism is rotatably fixed to the board 4 so that the pedal portion can be rotated up and down about the lever axis 9. The wheel 6 is fixed to the board 4 or the cover 5 with respect to the rotation axis 16. In the acting kickboard of the present application configured as described above, the user climbs on the board 4 so that one foot supports the body on the board 4 and steps on the pedal 7 with the other foot so that the wheel 6 rotates as shown in FIG. 2. The kickboard unit is moved.

The structure which rotates the wheel 6 connected to the four gear 37 is shown. Here, the chain 20 may be directly connected to the first gear 15 without the second gear 17 and the third gear 32. In addition, you may connect the 1st gear 15 and the 2nd gear 17 by chain. As shown in FIG. 10, the fourth gear 37 and the third gear 32 are configured to be located at the side of the board by the wheel connecting shaft 38 so as not to prevent the user from standing. Here, in the configuration in which the chain 20 is connected to the first gear 15 without the second gear 17 and the third gear 32, the driving unit and the first gear 15 are located at the side of the body and the fourth gear ( 37) is connected through the chain 20 and configured to bend so that only the pedal can be located in the center of the body. The drive unit and the first gear 15 are configured to be fixed using the same as the wheel connecting shaft 38 around the body.

Of course, in this configuration the center of gravity must be designed to come on board.

11 to 20 are related to the configuration in which the driving mechanism is replaced with the driving mechanism using the one-way bearing 50 in FIGS. 1 to 10. The configuration of the one-way bearing 50 is similar to that of FIGS. 1 to 10. Therefore, it will be understood by those skilled in the art without a detailed description, and thus will not be described in detail.

Figure 11 shows a one-way bearing drive mechanism as another embodiment of the present invention. As shown, the one-way bearing 50 is composed of an inner ring and an outer ring, and between them so that they can only rotate in different directions, the configuration is a bearing that is used for driving the rear wheel of the current bicycle In the present invention, the configuration is the same as that used. That is, since the configuration used in the rear wheel of the bicycle and a tool for locking and releasing bolts which rotate only in one direction called a so-called one is not described in detail. The unidirectional bearing drive mechanism of FIG. 11 consists of a bearing drive and wheel 6 consisting of a pedal 7, a lever 8, a unidirectional bearing 50, and a spring 51. Here, the lever 8 is connected to the outer ring of the one-way bearing 50 and the inner ring of the one-way bearing 50 is connected to the wheel 6, it may be connected to the opposite. In addition, the lever 8 is connected to the cover 5 forming a body skeleton through the spring 51, the user rotates the wheel 6 when the user presses on the pedal 7, and the pedal 7 springs when the user presses on the pedal. By 51, it returns to the upper original position again. This change is shown in FIG. 12, in which the spring 51 is not shown.

The spring 51 may be installed in a bearing and follows known techniques.

FIG. 13 shows an embodiment in which the drive mechanism of FIG. 11 is mounted on the kickboard section, in which the spring 51 is connected to the cover 5 and the shaft of the wheel 6 is connected to the cover 5 in the mechanism of FIG. 11. The configuration is similar to that of FIG. 3 except for the point. The position of the spring 51 is installed in a position where the lever 8 is appropriate to recover to its original position and has a low force when stepped on.

In FIG. 14, the inner ring of the bearing driving unit of FIG. 11 is connected to the rotational shaft of the first gear 15 instead of the wheel 6, and the same is the same as that of FIG. 4.

FIG. 15 is an embodiment in which the driving mechanism of FIG. 14 is mounted to the kickboard unit. The shaft of the spring 51 and the first gear 15 and the shaft of the wheel 6 are fixed to the cover 5, and the gear between the first gear 15 and the second gear 17, although not shown, is fixed. One more should be added to control the direction of rotation of the wheel (6). You can also adjust the speed with this additional gear. Others are similar to FIG. The driving mechanism as shown in FIG. 1 can enjoy the power kickboard of the present invention while moving backward or forward because the direction of rotation is free as the user intended.

FIG. 16 illustrates a configuration in which a gear and a gear are connected to the chain 20 in FIG. 15, and others are the same as the description of FIG. 15.

FIG. 17 is a model when the lever 8 extends forward in the bearing drive unit, which is the same as the description of FIG. 7, and FIG. 18 is a top view of FIG. 17.

19 and 20 are the same except that the bearing drive unit is installed in FIGS. 9 and 10.

FIG. 21 is a configuration for converting the vertical stepping force of the mechanism of FIG. 1 into a rotary motion, except that the pedal 7 is stepped on with the user's foot instead of the cylinder of the combustion engine. Such a configuration can be mounted similarly to that of FIG. 9 to be configured directly under a user.

Fig. 22 is a view showing the lever as a side, and the user can be positioned at a convenient position.

FIG. 23 is a drive mechanism in the case where 9 is located behind the rotating body 60, and 8 and 10 are in a straight line (an angle formed by 8 and 10 in FIG. 1 is 0 degrees), and may be a single bar. The rest is the same as that of FIG. 61 is a rotating shaft.

24 illustrates the operation of FIG. 23.

FIG. 25 is an embodiment in which the angles of 8 and 10 of FIG. 23 are not 0 degrees, and the angle can be determined in consideration of the force and the speed of the rotating body.

FIG. 26 is an example in which the rotating body of FIG. 23 is provided on the back side of 6, and the structure of FIG. 23 may be provided in front of 6 (see FIG. 4).

27 is a configuration in which 50 is configured to the wheels and 8 is fixed to 15.

Figure 28 is a drive mechanism using the lever of the present invention in the installation of the rear wheel of the demountable mechanism, by connecting the center of rotation of 9 to 16 rotates around 16 and the load is applied to most of the load on the board 6 The configuration can be prevented from bending the board so that this can be minimized. In this configuration, when stepping on 7 in the configuration as shown in FIG. 5 of the present application, since the loads at the points where the 9 and 4 parts meet with reference to FIG. There is a problem to be strong, but when configured as shown in Figure 28, because the load on all 6 to bear the load on 7 there is no load on the four. In the operation of Fig. 28, stepping on 7 rotates 15, the gear of 15 (not shown) rotates 17, and 6, which is fixed to 17, rotates. In the configuration of FIG. 28 as shown in FIG. 3, 16 and 14 need only be fixed to 4, and those skilled in the art can easily implement the description.

FIG. 28 shows a configuration for driving a rear wheel, which is mounted on the rear wheel portion of the apparatus as shown in FIG.

FIG. 29 shows the same concept as that in FIG. 28 except that the driving mechanism using the one-way bearing coincides with 16. FIG. In operation, when stepping on 7, the inner ring of 50 with the rotation center coincides with 16, the outer ring rotates by the operation of one-way bearing, and the protruding gear 81 is rotated by the gear attached to the outer ring (see Fig. 30). The additional gear 80 (refer to FIG. 30) fixed to 81 rotates about the additional gear shaft 82 to rotate 17 and rotates 6 (see FIG. 30) fixed to 17.

In connection of one-way bearing and eight, the gear on the outer ring of 50 has a constant contact with 81. Therefore, there is no need for gears other than the part in contact with 81, so that the outer ring can be made long in the outer ring so that the eight can be attached to the inner ring, so that the eight can move up and down to a predetermined angle. When one-way bearings are under load, make sure that it is time to step on 7. To get 8 back up again, connect the spring lamp and step up again. The inner ring is not shown in FIG. 29 and 8 is connected to the inner ring via the outer ring.

FIG. 29 shows a configuration for driving a rear wheel, which is mounted on the rear wheel of the apparatus as shown in FIG.

As shown in Figs. 28 and 29, the rear wheels bear the load so that the stability and robustness of the board can be realized, and the size of the component can be compressed. You can also use a chain to transfer the torque.

In Fig. 14 of the embodiment related to the above bearing drive, the one-way bearing is not connected to the lever, but the lever is attached and fixed at the center of 15, and the 15 is rotated up and down, and the one-way bearing is connected between 17 and 6 (a conventional bicycle). The same as the configuration of) may be configured. Similarly, the same principle applies to FIGS. 15, 16, 17, and 19.

Unlike the driving principle of FIG. 1, when driving with the driving principle of FIG. 10, the rotation direction becomes a problem, and thus the rotation direction should be adjusted by appropriately combining the gears. However, in the case of using the cha, for example, in FIG. As described above, in Fig. 16, the bearing may be provided on the rear wheel, so that it is not rotated except for the rear wheel unless the pedal is stepped on.

In addition, in all embodiments of the present invention, the driving unit may be installed on the rear side of the rear wheel to increase the length of the lever to reduce the force.

For example, in FIG. 3, 9 parts are configured at the rear of the wheel, and 9 parts are fixed by using 5 instead of 4 parts. The angle and length of the drive should be adjusted to allow the wheels to be driven and will not be described as it will be readily apparent to those skilled in the art.

For example, in FIG. 4, the drive unit and 15 may be configured on the right side of 6, and the lever may be extended to the current position. Therefore, in FIG. 5, the driving unit and 15 are located behind 6 (the end of arrow 6) and 9 is connected and fixed by a bar fixed to 5. In this case, the structure of the driving unit is changed, but the driving principle is the same, so those skilled in the art can easily implement without departing from the spirit of the present application. The same applies to FIGS. 3, 5, 6, 7, and 9.

In the present invention, the position of the pedal is configured in consideration of the weight center when determining the position of the pedal to prevent the kickboard is unstable because the user does not match the center of gravity of the kickboard.

All embodiments of the invention are equipped with a brake. It can also be installed on the handle. That is, you may comprise with the brake lining which catches the wheel shaft which is a brake used by the conventional bicycle, and may be comprised by the rubber which catches a wheel. This configuration follows the known method since it is currently used in bicycles. In this case, in order to prevent the user from being pushed forward when the brake is applied, the protrusion is installed in front of the board as a brake model of the car so that the foot can not be pushed forward. It is also possible to install a brake pedal on the board so that you can step on it. This brake pedal is installed in front of the board like a brake pedal in a car. When the pedal is pressed, the rubber brake or brake lining is operated by pulling the brake operating line. This configuration also has the effect of preventing the body from pushing forward when the user applies the brakes.

In addition, in all embodiments of the present invention, the handle 1 or the handle shaft 2 may be removed and the user may be configured to ride the present invention as if riding a roller board. It is also possible to install a chair on the board (4) to be able to sit.

In addition, shifting by adding gears may also use the shifting method used in a conventional bicycle as it is. It is also possible to use gears, such as gear shifting in automobiles. That is, all the techniques currently used in bicycles can be applied to the present invention.

In the present invention, the rear wheel may be two, in this case it can be configured to rotate the two wheels by transmitting a driving force to the axis connecting the two wheels, and those skilled in the art can be sufficiently carried out, the detailed description and drawings are not presented. . The present invention seeks to claim the right of the apparatus and method for all vehicles that the user can stand on one board and step on the pedal with the other foot.

The drawings are to be understood as possible only by themselves, and the detailed description is simply written.

All the driving principle and the configuration of the driving principle of the present invention is applicable to all the embodiments mounted on the kickboard in the present invention, it will not be described in detail because it will be seen by those skilled in the art that there is no difficulty in configuration. In addition, in mounting the driving mechanism of the present invention, it is also an important feature to maintain the rigidity of the board by approaching the rear wheel as much as possible to bear the load on the rear wheel.

In addition, the present invention is a concept that a large bike can stand standing, it can be configured to be smaller like a kickboard by reducing it.

In addition, since the part connecting the lever axis and the board on the board is most likely to be bent under the most force, it is also possible to use a method of securing by adding one more wheel right under this.

The present invention relates to a power quick board that is small and light, which is convenient to move and can move like a bicycle by driving wheels with the power of a foot, overcoming the disadvantage that the conventional quick board cannot use power, and the user stands on the foot by foot. It was able to transmit power. Therefore, it can be used for speedy recreation.
