The present invention relates to a skateboard, and more particularly, to a skateboard that is driven by the swinging motion and rotational motion of the two footsteps that can utilize a variety of technologies while the rotation radius is small, easy to change the direction and gaining propulsion force only by foot.

As is known, in the case of a skateboard with a separated footboard (Korean Utility Model Registration No. 20-0400918), both footholds are hinged through a connecting plate (or connector angle) in the middle, and wheels are installed at the bottom of both footholds. It consists of a structure.

Therefore, the user puts each foot on the footrest, while gaining propulsion while rotating the footrest hinged axis through the foot and twisting the waist and body. This has much effect on the development of balance and health promotion by whole body exercise. However, this requires a lot of exercise to twist the body.

In addition, the so-called S board is to utilize the driving force of the rotation wheel installed inclined to the board while rotating and repeating the movement of both boards about the longitudinal axis of the board.

However, this is a limitation in reducing the radius of rotation of the board, since the direction of the board is determined depending on the rotation wheel, it is difficult to use a variety of techniques.

Therefore, the present invention was created in view of the above-mentioned circumstances, and the rotation radius is small, easy to change the direction and driving by swinging and rotating motions of both footsteps to make use of various technologies while gaining propulsion force only by footing. The purpose is to provide a skateboard.

Specific means of the present invention for achieving the above object, in the skateboard is used to drive by lifting the propulsion force on the ground with both feet,

A front footrest having an area on which one foot can be placed;

A rear footrest having an area on which the other foot can be placed;

A connection plate disposed between the front footrest and the rear footrest is provided;

The propelling wheels are disposed on the bottom surfaces of the front foot plate and the rear foot foot to rotate in contact with the ground;

At least a pair of steering wheels are installed on the bottom of the connecting plate to be in contact with the ground and to rotate and to change directions;

First and second connecting means connecting the front and rear footplates to the connecting plate in a straight line to enable swing and rotational movements;

And first and second elastic return means for returning the rotational movements of the front footrest and the back footrest to the original position with elastic force.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 1, in the present invention, the front footrest 20, the connecting plate 40, the rear footrest 30 is sequentially connected. That is, the connecting plate 40 is located in the middle of the front footrest 20 and the rear footrest 30 is connected.

Both the front footrest 20 and the back footrest 30 have a sufficient area to put either foot on.

The propulsion wheels 21 and 31 are disposed on the bottom surfaces of the front footrest 20 and the rear fan footrest 30 and are disposed on a straight line (X axis) as shown in FIG. 3 to rotate in contact with the ground.

The bottom of the connecting plate 40 is provided with at least a pair of steering wheels 41 and 42 which are in contact with the ground and capable of rotating and changing direction. In this embodiment, the steering wheels 41 and 42 are arranged opposite to each other about the X axis.

The front footrest 20 is connected to the connecting plate 40 via the first connecting shafts 51 and 52, and the rear footrest 30 is connected to the connecting plate 40 via the second connecting shafts 61 and 62. 40).

These first and second connecting shafts have the same configuration, and any one of the first connecting shafts 51 and 52 will be described.

For example, as shown in FIG. 5, the first connecting shafts 51 and 52 are rotatably connected with respect to the X axis through the bearing 53, and the other ends of the first connecting shafts 51 and 52 are connected to the front plate 20 and the connecting plate 40, respectively. It is connected by hinges h1 and h2.

Therefore, the front footrest 20 and the rear footrest 30 is basically two kinds of swing motion and rotational movement occurs selectively or simultaneously.

First, as shown in FIG. 4, the front and rear scaffolds 20 and 30 may swing in the F direction and the R direction using the front hinge h1 and the rear hinge h2 as the centers O1 and O2. That is, the front and rear scaffolding 20, 30 has a secondary rotation radius of the propulsion wheel (21, 31) the first rotation radius of the hinge center (O1) as the rotation axis) and the other hinge center (O2) as the rotation axis. Take a swing with your feet.

In this case, the hinge plate h2 of the connecting plate 40 is fixedly fixed to induce a swing motion with only the hinge center O1 of the front footrest 20 and the rear footrest 30.

Thus, the present invention can be configured to swing the front footrest 20 and the rear footrest 30 in one or two hinge centers. When the two hinges are configured, steering of the front and rear scaffolds 20 and 30 may be further improved.

Second, the front and rear scaffold 20, 30 can be rotated in the direction of the arrow (A1) with respect to the first and second connecting shafts (51, 52) (61, 62) as shown in FIG. That is, the front scaffold 20 may rotate in the direction of the arrow A2 about the X1 axis passing through the center of the first connecting shafts 51 and 52. In addition, the rear footrest 30 may be rotated about the X2 axis passing through the center of the second connecting shaft (61, 62).

As such, the front and rear scaffolds 20 and 30 induce a swing movement using the hinges h1 and h2 and rotate using the first connecting shafts 51 and 52 and the second connecting shafts 61 and 62. By inducing the movement of the propulsion wheels (21, 31) to move to the left and right at the same time to relieve the direction with the driving force is to get.

Meanwhile, the torsion springs 71 and 72 may be further installed as shown in FIG. 5 so that the front and rear scaffolds 20 and 30 are rotated in the directions of the arrows A1 and A2 and then easily returned to their original positions.

In this embodiment, the torsion springs 71 and 72 are positioned inside the first connecting shafts 51 and 52 and the second connecting shafts 61 and 62, respectively, and one end thereof is fixed to one connecting shaft 51 and 61. And the other end is fixed to each other connecting shaft (52, 62) is installed.

The operation of this embodiment configured as described above will be described.

First, when the skateboard 10 of the present invention is placed on the ground, the front footrest 20, the connecting plate 40 and the rear footrest 30 by the torsion springs 71, 72 as shown in Figs. It is placed on a date. At this time, the skateboard 10 is all four wheels (21, 31, 41, 42) is in contact with the ground, so that it is placed in the horizontal state.

Therefore, the two axes X1 and X2 passing through the center of the first connecting shaft 51 and 52 and the second connecting shaft 61 and 62 are aligned with each other.

In this state, the user puts one foot on the front footrest 20 and the other foot on the rear footrest 20 as shown in FIG. 3 and rides the skateboard 10 using the movement of the foot and the body.

That is, according to the movement of the foot and the body, the front footrest 20 and the rear footrest 30 are left and right swing movements around the X1 axis and the X2 axis, respectively, about the rotational movement and the hinges h1 and h2.

In this way, the propulsion force is generated as the propulsion force is generated as the propulsion wheels 21 and 31 move to the left and right due to the swinging motion and the rotational movement of the front footrest 20 and the rear footrest 30 to move the skateboard 10 forward. I will go forward.

As the front and rear footrests 20 and 30 are moved to the left and right as described above, the connecting plate 40 interposed therebetween follows the steering wheel 41 and 42 while steering the steering wheel.

In this embodiment, both ends of the first connecting shafts 51 and 52 and the second connecting shafts 61 and 62 are configured to be rotatable, but the front and rear scaffolds 20 and 30 may be fixed even if either one is fixedly installed. Propulsion driving is possible because rotational motion and swing motion occur.

Meanwhile, in the present invention, the torsion springs 71 and 72 are installed in the first and second connection shafts 51 and 52 and 61 and 62, respectively, but the present invention is not limited to the installation structure and the number thereof.

In addition, in the present embodiment, two steering wheels 41 and 42 were used for the connecting plate 40, but the present invention may be configured with one steering wheel in the center.

The skateboard 10 constructed and used as described above has the following advantages.

Rotation radius is small because the front footrest 20 and the rear footrest 30 performs a swinging movement while drawing a radius from side to side via the intermediate connecting plate 40. Therefore, it is easy to switch the echo and ride in a narrow space.

In addition, since the divided two front footrest 20 and the rear footrest 30 can freely manipulate the swing motion and the rotation motion can use a variety of techniques.

In addition, since the propulsion wheels 21 and 31 can be inclined, braking is easy and the braking force is excellent.
