Description

{Course changing possible skateboard}

The present invention relates to a skateboard capable of reversing direction, and more particularly, to a skateboard capable of reversing direction to have a steer ability to selectively steer the traveling direction of a running board without the need for turning driving when changing the direction of the skateboard. It is about.

Conventional skateboards support the driver's one foot on a board with wheels, and then push the other foot off the ground in the direction of propulsion to give propulsion and raise both feet on the top of the board while accelerating the front and rear feet. By alternately intersecting the position points in the opposite direction, the skateboard can be moved in the corrugated copper line.

On the skateboard, the driver could roll the ground by himself to generate artificial propulsion to move forward, but this limited the forward power of the skateboard, which reduced interest in the movement. There was a problem that caused a safety accident.

In recent years, to compensate for this problem, a board has been proposed in which a driver may repeatedly advance the board without generating a ground and generate a forward force.

The board of the prior art as shown in the Republic of Korea Patent Application No. 2003-25663, in the skateboard comprising a connecting element for fixing the front board 10 and the rear board 20 in a spaced apart state, the two boards At least one of (10, 20) includes at least one directional caster (13, 23) attached to the bottom of the plate (11, 21), wherein the connecting element is made of an elastic body to allow torsional or bending elastic restoration.

In this skateboard, when the driver tilts the foot on the front board 10 to the right in the direction of travel, the roller arm 35 of the directional caster 13 of the front board 10 returns to the left in the opposite direction and rolls. 36 rotates to the right to make the right turn.

On the contrary, when the driver tilts the foot on the rear board 20 to the right in the direction of travel, the roller arm 25 of the directional caster 23 of the rear board 20 returns to the left in the opposite direction and the roller 26 moves to the right. Rolled toward the rear board 20 is rotated to the left as a result of the right turn.

On the basis of the two cases, the front board 10 is tilted to the right in the direction of travel and the rear board 20 is tilted to the left to make the right turn of the small radius as a whole to move forward.

In addition, in order to attempt the direction change after the forward speed of the board is generated, the inclination angles of the front board and the rear board are inclined in the rotational direction so that the board is turned to a curvature of a large diameter, thereby changing the direction.

However, when the skateboard according to the prior art turns the turning section divided into the turning entry section, the turning progress section and the turning exit section, the inertial force is generated at the center point of the board by the lateral acceleration of the board. This can cause rolling of the board.

Due to such a rolling phenomenon, repeated shaking and inaccurate rolling phenomena occur on the board, thereby degrading a passenger's parallel ability and running ability.

This is directly related to the safety accident of the board, and it can be seen that the incidence of such a safety accident is high when turning the board.

Secondly, when turning the board, the board is rotated while the direction of the roll rotation is changed in the turning direction by changing the inclined angle of the board in the turning direction, but the variable range of the inclination angle of the board to perform the turning function is Because of the limitations, the board's turn curvature had to increase.

As a result, the speed and instantaneous steering ability of the skateboard running in a large turning copper line is reduced, and the board is difficult to change direction in a space in which a turning space is not provided.

In particular, when the board is climbing on the slope, the turning power is lost as the forward force is eliminated, there was a disadvantage that it is difficult to run anymore, there was a problem that can cause a safety accident due to this problem.
