Description

{A driving board}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a board capable of traveling through a grounding force, and more particularly, to a board capable of traveling on a bottom surface of a board, The present invention relates to a board capable of converting a traveling mode into a vertical mode for traveling, a traveling mode for traveling, and a traveling mode for the occupant through the board.

Usually, the play board is provided with a pivoting plate for placing both feet, and a directional wheel is coupled to the bottom of the pivoting plate.

In the above-mentioned board, if an initial user wishes to travel, the wheel is provided with a rotatable wheel on the bottom of the foot plate, and one foot is placed on the foot plate and the foot plate is driven in the form of spurting the floor with the other foot.

In this case, when the user wants to travel, the user has to continue to play the ground, which is a difficult problem to enjoy.

In order to solve this problem, it has been proposed that a pair of pivot plates are connected by a connecting member in a state of being spaced apart at a predetermined interval, and the connecting member is made of an elastic body to provide an elastic restoring force according to the torsion.

This is because when the user places both feet on the pair of pivot plates and repeats the operation of tilting each pivot plate alternately with respect to the connecting member, the wheel becomes propulsive and can travel.

In other words, the conventional method of obtaining propulsive force by rolling the foot is avoided, so that the user can obtain driving force by alternately moving the two feet or the body while repeatedly performing the biting motion in the state where the user is climbing on the foot plate.

However, in the case of the above-mentioned board, it is convenient to use for driving, but when the user wishes to store or transport the board, the wheel protrudes from the foot plate, which makes it difficult to carry and store the board.

As an example of a conventional board, a Korean skateboard skateboard is disclosed in Korean Patent Registration No. 10-0752570 on Aug. 29, 2007.

This is because the front plate; A rear plate disposed on the rear side of the front plate; Rollers respectively installed on the front plate and the back plate; A first extension portion extending from a rear side of the front plate and connected to the folding portion, the folding portion including a folding portion for foldably connecting the front plate and the backing plate; And a second extending portion extending toward the front side of the rear plate and connected to the folded portion, wherein the folded portion includes: a first coupling member coupled to an end of the first extending portion; A second coupling unit coupled to an end of the second extension unit; A hinge hinged to one side of the first and second assemblies; And a locking pin for locking the other side of the first and second assemblies opposite to the hinge.

However, there is a merit that folding can be performed in the above case, but there is a problem that it is difficult for the user to easily fold.

Korean Patent Laid-Open Publication No. 10-2007-0087370 discloses a skateboard having a variable-angle type caster, which was disclosed on Aug. 28, 2007.

The present invention relates to a skateboard in which a directional castor is mounted on a bottom surface of an integrated boarding board, wherein the casters are hinged to a bottom surface of a board, and the hinge joint portion is resiliently supported by an elastic member, And the front and rear casters are each made to change the inclination angle upon collision with a change or a road surface.

However, in the case of the board described above, there is a problem that the wheel moved from the ground is positioned at a predetermined angle.
