Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

As shown in FIG. 1, the skateboard according to the present invention is configured to generate self-driving force and to easily generate a sufficiently large force so that children, teenagers as well as adults can have fun.

To this end, the skateboard according to the present invention includes a cylindrical body frame 100 having a trapezoidal shape with an upper surface opened.

In this case, the body frame 100 may have various shapes without being limited to the illustrated shape.

In addition, the front and rear wheels 110 and the rear wheel 120 are provided at the front and rear ends of the main body frame 100. The front wheel 110 is a kind of steering wheel which is driven idlely, and the rear wheel 120 has a driving force. It is a kind of driving wheel that generates.

In addition, the rear wheel 120 is fixed to the drive shaft 130, the drive shaft 130 is rotatably fixed to penetrate the body frame 100 in its width direction.

In addition, as shown in FIGS. 2 to 4, the drive sprocket 132 is fixed to the drive shaft 130 integrally.

At this time, the drive chain 140 is wound around the drive sprocket 132, and the drive chain 140 is wound around the one way sprocket 150, which is a power generating means, like a chain of a bicycle. do.

Here, the one-way sprocket 150 is a kind of ratchet, that is, a sprocket which rotates only in one direction as a latch gear and idlely rotates in the other direction, and the driving sprocket 132 ) Should be made of one-way plaque.

The one-way sprocket 150 and the driving sprocket 132 may have different diameter ratios (gear ratios) to smoothly and easily transmit power, and the one-way sprocket 150 may drive the sprocket 132. It is desirable to increase the driving force by making it larger.

In addition, the one-way plaque 150 is fixed to the power generating shaft 160.

In this case, the one-way placket 150 may be installed inside the main body frame 100 within a range that does not interfere with the operation rod 200 to be described later, preferably installed outside the main body frame 100. do.

In particular, the one-way sprocket 150 may be installed one, it is more preferable that two one by one each on both sides of the outer side of the main body frame 100 in order to generate a stable propulsion force.

According to a preferred embodiment, at least one, preferably (b) for the elastic return force of the operating rod 200 when the drive chain 140 is installed in a caterpillar form as shown in Figure 2 (a) Two torsion springs can be installed.

The torsion spring is preferably a first torsion spring (170) and the second torsion spring (180), one end of which is caught in the form of gripping while wrapping the operation rod 200, the other end of the body frame 100 It is configured to be caught on the wall surface.

Then, the driving force generated by the power generating shaft 160 formed integrally with the operating rod 200 by providing the elastic return force when the operating rod 200 is the seesaw movement of the driving chain 140 through the one-way sprocket 150 ), Through the driving sprocket 132, the drive shaft 130 is transferred to the rear wheel 120 to obtain a driving force.

In particular, when the one-way sprocket 150 has two driving rods 200, driving force is generated at all moments of lifting and lowering from side to side, starting from the power generating shaft 160, so that it can be driven at a higher speed. do.

As another example, as shown in FIG. 3, the drive chain 140 partially wound around the one-way sprocket 150 and the driving sprocket 132 is provided, and first and second springs 172 and 182 are respectively provided at both ends of the driving chain 140. ) Is connected, the first spring 172 is provided on the one-way sprocket 150 side and is a spherical spring fixed to the main body frame 100 to be operated in the always winding direction, the second spring 182 is usually If coil spring of is enough.

Therefore, since the spiral spring is wound in the driving direction and the coil spring is tensioned at the same time, there is no problem in generating the driving force. In the opposite direction, the spiral spring is idlely rotated so that it is easily returned by the elastic return force by the coil spring. In order for the elastic modulus of the coil spring to be larger than the elastic modulus of the spiral spring.

On the other hand, the stepper 300 is installed at both ends of the operation rod 200.

At this time, the scaffold 300 is the seesaw movement of the operating rod 200, so that the level of the operating rod 200 should always be kept horizontal regardless of the inclination of the occupant to improve the safety of the occupant and the convenience of boarding, for this purpose As shown in 5, the fixed guide 310 is integrally fixed to both ends of the operation rod 200, the flow guide 320 is assembled to the fixed guide 310, the upper end of the flow guide 320 The footrest 300 is fixed to the seated state.

In this case, the fixing guide 310 is formed in a semi-cylindrical shape, the inner surface of the guide ribs 312 having a half-shaped protruding, the flow guide 320 in a shape corresponding to the fixing guide 310 It is formed to be assembled so that the inner surface of the fixed guide 310 and the outer surface of the flow guide 320 is in contact with each other, the guide rib 312 is inserted into the flow guide 320 along the curvature has a longer length Guide slot 322 is formed.

In addition, the separation prevention member 330 is fixed to both sides of the fixing guide 310 to prevent the separation when the flow guide 320 is assembled.

Therefore, when the operation rod 200 is inclined while descending, the flow guide 320 slides while riding on the guide rib 312 of the fixed guide 310 to allow the scaffold 300 to be horizontal, and vice versa. When the operation rod 200 rises in the direction, the opposite operation is caused to keep the scaffold 300 horizontal at all times.

As another example, as shown in (a) and (b) of FIG. 6, the operation rod 200 ′ is divided into two in the width direction, and the connecting rod 202 is interposed therebetween, and the connecting rod 202 is provided. And two actuating rods 200 'are eccentrically hinged through the first and second hinge shafts 204 and 206 so that the scaffold 300 fixed to the upper end of the connecting rod 202 is driven by the actuating rod 200'. Even if it is arranged to be inclined while being raised and lowered, the footrest 300 is better to be always configured so as not to impose a burden on the passenger's ankle.

Self-driving skateboard according to the present invention having such a configuration is pressed down by pressing the force on either side in the state in which the occupant puts the foot on the footrest 300 is pressed down when the footrest 300 is pressed.

Then, the power generation shaft 160 is rotated, the one-way sprocket 150 is installed integrally therewith, the drive sprocket 132 connected to the drive chain 140 is driven to rotate the drive shaft 130 It will generate a driving force.

Thereafter, when the other footrest 300 is pressed, the operation rod 200 is easily returned due to the elastic return force due to the plurality of springs, and at the same time, the opposite footrest 300 descends to rotate the opposite one-way sprocket 150 again. The driving force is generated. At this time, the one-way plaque which has been operated a while ago is idlely rotated.

That is, by configuring the two one-way sprocket 150 is rotated in one direction in the opposite direction to each other, the driving force is always generated in the same direction, but when the opposite rotation, that is, when the footrest 300 is raised, the idler is always idle. Only by pressing the footrest 300 in the form of seesaw propulsion is always generated and the skateboard is advanced.

As such, the skateboard according to the present invention can be configured to have a more stable and sufficiently large driving force, it is expected that it can be used as an interesting exercise equipment in various layers from children, adolescents to adults.
