The present invention relates to a skateboard (skateboard, just referred to as 'board' in the art), and more particularly, to a skateboard capable of self-propulsion by the user's power without directly contacting the ground.

Such a skateboard is known in the prior art Patent Registration No. 10-0394848 (skateboard with a directional caster) or Patent No. 10-0612427 is well known and its configuration and action is elastic with the front board and the rear board spaced apart Each of the front and rear wheels of the rear board and the rear wheel of the rear board are provided by a directional caster which is connected to a connecting element including an element and has a directional caster on the bottom of the front board and the rear board to change the direction of the board. The invention relates to a skateboard that enables steering while minimizing the radius of rotation and maximizing the action of the directional casters.

 However, as described above, when the front board and the rear board are separately set and connected in a spaced apart state, the following problems occur.

 1. The use of the entire board is reduced and the area of use is reduced, so the choice of the user's foot is narrowed, and thus it is difficult to display the skateboard's unique and diverse riding technology.

 2. When the space between the front board and the rear board is narrow, part of the user's body is caught between the spaces when the front board and the rear board are inclined oppositely.

Therefore,

While providing a skateboard in the form of a plate, the board constituting the board to enable die-banding banding, while providing a board to which the principles of progression, such as prior art, registered patent No. 0394848, is applied to the user using the whole plate. Expand your landing area to use the skills of a more advanced classic skateboard.

Hereinafter, with reference to the accompanying drawings discloses a skateboard of the present invention.

1 to 3,

The first side 11 and the second side 12 to allow cross-wrenching, that is, die-bending in a diagonal direction, through section borders C1 and C2. Plate (10) divided into four triangular sections (Section) divided into a third side (13) and a fourth side (14); Refractive portions 40, 41, and 42 to impart a refraction, bending function so that the boundary between each side (11, 12, 13, 14) can be refracted.

In the drawing, the front side section in the traveling direction of the skateboard is the first side; A rear side section on the second side; One side portion of the left and right side is the third side; The other side section of the left and right sides becomes the fourth side.

Traveling means (driving wheels) such as wheels capable of traveling on the ground and steering are provided on the plate, and in particular, it is configured to include one or more directional casters 20 to facilitate the provision of steering and propulsion force. The figure is an embodiment when the directional caster is provided on the bottom of the first side 11 and the second side 12.

The directional caster is pivot (P) coupled to the wheel (W), the arm bracket (B) receiving the wheel and the top end of the arm bracket inclined at a wedge angle in the advancing direction with respect to the horizontal surface of the plate. When the first and second side plates are inclined in the same or staggered direction, it refers to the caster that is turned in proportion to the degree of inclination.

In the skateboard of the present invention, the directional caster is provided to protrude forward and backward of the plate; Or, it may be provided on both sides of the plate,

The provided form may be attached in a fixed, removable, positionally movable, and may also be attached in the form of a reference to the steering means of the above-mentioned Patent Publication No. 10-0612427.

In the figure, the case where it is attached to the bottom surface of the said 1st side 11 and the said 2nd side 12 of the said board | plate material 10 is shown.

The refractions 40, 41, and 42 are each of the sides (11, 12, 13, 14) to be sculpted and coupled to each other by using a separate bent, refracted member (T), As shown in FIG. 3 (b), the refraction portion 40 and 42 may be formed in the section boundary C2 between the second side 12 and the third side 13. The second side and the third side by using a refractive member (T) capable of refraction or elastic refraction refraction is hinged (Hinge) method to combine.

In addition, it is possible to provide each side 11, 12, 13, 14 as a member of one plate and to process the member so that only the refraction portion 40 on the section boundaries C1 and C2 can be refracted. Referring to FIG. 3A, the refraction portion 40 is formed by forming a hinge between the first side 11 and the third side 13 by recessing the recessed groove U along the section boundary C1. , 41).

4 and 7 show diagonal twisted wrenching operations in which the first side 11 and the third side 13 cross each other due to the refraction of the refraction portion 40 as another embodiment. . At this time, the operation of the directional caster 20 is shown in Figure 5, the front directional caster 20F attached to the bottom of the first side 11 is inclined to the place where the first side is inclined (down) To switch (DF); In Fig. 5B, the rear directional caster 20R provided at the bottom of the second side 12 turns DR to the inclined place where the second side is tilted down. As the skateboard progresses in a zigzag form, it can act as a steering force to exert a driving force or to change direction.

As shown in FIG. 6, the third and fourth side edges of the sheet may be curved or cut in shape in consideration of design.

According to the invention,

Since the board constituting the board can be die-diagonally banded while providing a skateboard in the form of a plate, while providing a board to which the principle of progression, such as the prior art, is registered, the user can use the whole board. Expand your landing area to take advantage of advanced classic skateboarding skills.
