Of course, the plate is to maintain the strength to support the weight of the user, if possible the elastic member is used so that the user as shown in Figure 4 the first side 11 and the second side of the plate 10 It is desirable to make diagonal torsion wrenching (12) in the mutually staggered direction so that it can be elastic torsion or elastic restoring thereafter.

On the other hand, at the time of the trench as shown in Fig. 4, the forward directional caster 20F attached to the bottom of the first side 11 in Fig. 5A is where the first side is inclined down. Direction change to 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 fashion, it can exert momentum and change direction. 8 is an example of bending in a direction different from that of FIG. 4.

In addition, since the plate is included in the third and fourth sides of the plate and the plate is flexible, the support means 30 may be required to prevent bending of the plate. Support rods coupled to the four edges are possible. In addition, the shape of the support bar may be rod-like, plate-like, pipe, etc., and must be close to the center side of the plate in a range such that the plate is not bent as shown in the outermost edge of the plate edge or as shown in FIG. Can be attached. Figure 1 experience the support rod is a form surrounding the outermost edge of the plate, Figure 3 (A) is attached to the bottom of the plate edge or Figure 3 (B) top, Figure 3 (C) the outermost edge of the plate It can be configured in the form that is coupled to the opposite side, the form is attached to the bottom portion of Fig. 3 (d), and the shape in which the edge of Fig. 3 (d) is inserted. In addition, the cross section of the support means 30 or the support rod is not limited to any specific form such as an annular, rectangular, rectangular, C-shaped.

In FIG. 6, the edge of the plate may be curved or cut in shape in consideration of design, and the supporting means 30 formed at the edge may be formed and provided along the shape of the edge. .

The planar shape of the support means 30 can be a variety of forms and the triangular form as shown in Figure 7 is one example.

On the other hand, as shown in Figure 3 (e) the support means 30 can be configured by a method of bending or extending the edge of the plate downward (or upward), as in the case of Figures 9 and 10 The support means 30 may be configured by bending or extending the edge of the plate 10 vertically at an obtuse angle, a right angle or an acute angle, and in this case, the whole plate may be formed by one mold. At this time, it can be seen from the drawing of FIG. 10 that the support means and the auxiliary support means are provided in a form surrounding the edges of the first to fourth side plates.

As shown in Figures 11 to 14, the support means can be configured in a plurality of to strengthen the strength to support the direction of the horizontal, vertical, diagonal direction is possible and the configuration method is the section boundary (C1, The support rod may be coupled to the first side, the second side, the third side and / or the fourth side to avoid C2) or may extend from the plate. Of course, at this time, it does not necessarily need to be symmetric such as symmetry, front-back symmetry, diagonal symmetry, and asymmetry is possible depending on the purpose and design aspects.

The dashed dashed line used as the section boundaries C1 and C2 in the figure is an imaginary line.

In particular, the first side and / or the second side may be provided with supporting means to prevent bending of this portion, and may be assisted and reinforced to prevent bending of the third and fourth sides.

As shown in FIG. 15, the driving means fixing portion 20P may be directly provided on the supporting means, and the plate may be supported and the driving means may be fixed to improve the robustness.

Fig. 16 shows a plate member 10 having a reinforcing support portion EF formed therein, which includes support means 30 for preventing the waist of the plate member from being bent.

17 to 20 may be formed to avoid the section boundary (C1, C2) of the formation of the reinforcing support (EF), or to cut the groove or to cut a plurality of holes in the section boundary, as shown in the figure This is to facilitate the bending (bending) of the section boundary. In this case, the reinforcement support part EF may serve as the support means 30.

In order to facilitate the refraction on the section boundary, the width, size, depth, etc. may vary depending on the strength, hardness, and elasticity of the plate.
