The present invention relates to a skateboard, and more particularly to a skateboard configured to move forward with its own propulsion force as the scaffold member is elevated.

In general, skateboards put the wheels 20 on the bottom of the plate-shaped scaffold member 10 on which the user can put both feet, and put the two feet on the board and move one foot in a zigzag to obtain driving force. Or, one foot can be placed on the board and the other foot can be used to gain propulsion by kicking the ground, and by driving the sliding of the slope by gravity, leisure sports that can implement various stunts using the propulsion. It is an appliance.

However, this skateboard (1) has a limit in obtaining continuous and smooth mobility because the propulsion force is obtained by the body motion or the inclined surface of the occupant.

In addition, it is difficult and hard to gain propulsion, and the support points are used to seesaw in the width direction of the board to obtain propulsion power in both the front and rear wheels. There was a problem that was not easy.

The present invention has been proposed in view of the above problems, and its object is to provide a skateboard configured to move forward with its own propulsion force as the scaffold member is elevated.

According to a feature of the present invention for achieving the above object, in a general skateboard that the wheel is rotatably coupled by a wheel shaft to the lower portion of the foot member on which the user puts the foot, the foot member is supported on the upper surface The mounting frame to be coupled and the support frame to which the wheel shaft on which the wheel is supported are coupled to the bottom hinge are rotatably coupled to each other, and the restoring spring is mounted between the mounting frame and the support frame to return the folded mounting frame to its original position. On the wheel shaft, the wheel is supported, the ratchet gear is rotated in one direction while the power is transmitted. The ratchet gear is coupled to the bottom of the support frame, and the ratchet gear is rotated according to the rotation of the mounting frame. Skewer characterized in that the rack gear is configured to support the coupling The tree board is provided.

Hereinafter, the present invention will be described in detail with reference to the attached drawings skateboard as follows.

Figure 2 is an exploded perspective view showing a skateboard according to an embodiment of the present invention, Figure 3a and Figure 3b is a side view showing the assembled state of the skateboard of the present invention.

The skateboard 100 of the present invention as shown is a general skateboard 100 made of a wheel 120 is rotatably coupled by the wheel shaft 130 to the lower portion of the footrest member 110 on which the user puts his foot. ),

The front end portion of the support frame 150 is supported by the mounting frame 140, the foot member 110 is coupled to the upper surface and the wheel shaft 130 on which the wheel 120 is supported is supported on the bottom hinge ( 141 is coupled, between the mounting frame 140 and the support frame 150, the restoring spring 160 to rotate the mounting frame 140 is rotated to the original position is supported, the wheel 120 is coupled to the support wheel On the shaft 130, the ratchet gear 170 which is rotated in one direction and transmitting power is supported and coupled, and the bottom surface of the support frame 150 is engaged with the ratchet gear 170 to rotate the mounting frame 140. In accordance with the rack gear 180 to rotate the ratchet gear 170 is coupled to support, the user rotates the mounting frame 140 in a state where both feet are placed on the scaffold member 110 and the rack gear 180 and Combined to be interlocked by the ratchet gear 170 and the wheel shaft 130 It is configured to advance the skateboard 100 by rotating the wheel (120).

In addition, the mounting frame 140 is a rack gear 180 on the bottom and the coupling frame 140-1 fixedly coupled to the front of the support frame 150 as shown in Figure 4 and 5a and 5b in some cases. Is formed into a rotating frame (140-2) is provided is rotatably connected by the hinge 141, the scaffold member 110 is also the coupling frame (140-1) and the rotating frame (140-2) It is formed by separating the fixed scaffold member (110-1) and the rotating scaffold member (110-2) respectively fixed to the rotation frame 140 with the other foot in a state where the user put one foot on the fixed scaffold member (110-1) It may be configured to more smoothly rotate the wheel 120 coupled to interlock by the rack gear 180, the ratchet gear 170 and the wheel shaft 130 by rotating the -2).

In addition, at least one interlocking gear 190 as shown in FIG. 6 between the ratchet gear 170 supported and coupled to the wheel shaft 130 and the rack gear 180 supported and coupled to the mounting frame 140. Is rotatably installed, by extending the conveying range of the rack gear 180 meshed with the ratchet gear 170, the wheel 120 is rotated more by one rotation of the mounting frame 140 The skateboard 100 may be configured to be advanced.

Meanwhile, a protective cover 151 surrounding the ratchet gear 170, the rack gear 180, and the wheel shaft 130 may be coupled to the bottom of the support frame 150 to be generated when the skateboard 100 is used. It can be configured to prevent a safety accident in advance.

The action of the skateboard of the present invention configured as described above is as follows.

When using the skateboard 100 of the present invention usually one foot is placed on the scaffold member 110 and the other foot kicks to gain ground.

In addition, if you want to get the propulsion force in the state of placing both feet on the footrest member 110 of the skateboard 100 of the present invention, put one foot on the fixed footrest member 110-1 to hold the center Rotate the footrest member 110-2 by pressing on the other foot.

Then, the rack gear 180 located on the bottom of the rotating scaffold member 110-2 rotates the ratchet gear 170 and at the same time the wheel shaft 130 to which the ratchet gear 170 is coupled rotates the wheel ( 120 is rotated to allow the skateboard 100 to move forward as a whole.

In addition, when the foot is rotated by the rotating scaffold member 110-2, the rotating frame 140-2 and the rotating scaffold member 110-2 are positioned by the restoring spring 160.

As described above, the skateboard of the present invention usually gains propulsion by putting one foot on the ground and kicking the ground on the other, as well as rotating the rotating frame even when both feet are placed on the skateboard to obtain propulsion of itself. Therefore, the effect of making the skateboard more fun and enjoyable.
