Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding structure for a moving means, and more particularly, to a folding structure for folding a steering unit provided on a moving means such as a kickboard, a roller board, a bicycle,

Generally, of the moving means such as a kickboard, a roller board, a bicycle, a scooter and the like, the steering portion is vertically formed by a body supported by the front and rear wheels, for example, a handle for adjusting the running direction of the board.

Particularly, a kickboard, a roller board, a scooter, etc. are configured to be able to enjoy the feeling of speed by raising the foot on the board while steering the steering part, specifically, steering the steering wheel.

However, the above-described moving means such as a kickboard has a problem that the steering portion is formed in an upright shape extending in the longitudinal direction, and is not easy to carry.

In order to overcome the above-mentioned problem, a general kickboard is provided with a folding mechanism to fold the kickboard. In Chinese patent document CN2425682, the front handle is folded on a footboard through a folding mechanism such as a joint shaft, If not, the kickboard can be handed in by hand.

However, such a kickboard has a certain weight, which causes fatigue and inconvenience to be carried by a person for a long period of time.

In addition, in WO99 / 00290, both the footrest and the handle are made up of several independent parts to reduce the length of the footrest and the handle, and the hinge provided between the individual parts causes the respective individual parts to rotate relatively, It can be expanded and contracted by a slide method. This can reduce the size of the kickboard, which can be carried by hand or even in the bag.

In the above-described conventional kickboards, a foot plate, that is, a portion to which the board and the steering unit are connected so as to be foldable, is formed in a sliding manner so that the center of gravity is shifted. In the case where the steering unit is vertically installed on the board, And the steering part of the kickboard may be shaken during running.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a folding structure in which a handle is folded with one touch without causing a gap at a portion where a handle and a board are connected.

The present invention

A first shaft groove which is hollow and has a first shaft groove which is connected to the first shaft groove through which a shaft extended in the longitudinal direction is inserted and which is connected to the outer side of the first shaft groove, An upper hinge having a locking groove; And

A second shaft groove extending in a longitudinal direction and having a shaft penetrating through the first shaft groove to be connected to the first shaft groove, and a locking portion passing through the first locking groove so as to be adjacent to the second shaft groove, And a lower hinge provided with a second locking groove to be connected thereto;

The shaft is connected to the first shaft groove of the upper hinge and the second shaft groove of the lower hinge so that the shaft is connected to the first locking groove of the upper hinge and the second locking groove of the lower hinge, Lt; / RTI >

The folding structure according to the present invention has an effect that a clearance is not generated at a portion where a handle and a board are connected, and the folding structure can be folded with one touch and carried.
