The wheel member described below may be applied to the front wheel of the board, and the rear wheel will be described based on the assumption that it is used as it is mounted on the board.

The fixed connection part 110 is a connection member mounted on the rear surface of the board.

A separate height adjustment member (not shown) for height adjustment may be further positioned between the fixed connection unit 110 and the rear surface of the board.

In addition, the fixed connection part 110 may be fixedly coupled to the board through a coupling member such as a bolt/nut.

One surface of the fixed connection unit 110 may be formed flat as a portion that directly contacts the rear surface of the board or abuts the height adjustment member. A first through coupling member 112 and an insertion groove 114 may be formed on the other surface of the fixed connection part 110.

At this time, the first and second rotational joints 130a and 130b may be coupled to the body 120 so as to have an angle capable of returning to the original position by gravity.

The first and second rotational joints 130a and 130b have a coupling bolt member formed at one end and a through hole formed at the other end, respectively. Each of the coupling bolt members formed in the first and second rotary joints 130a and 130b may be inserted into the joint connection holes 126a and 126b formed at the other end of the body 120, respectively.

That is, the coupling bolt member formed in the first rotary joint portion 130a is inserted through the first joint connection hole 126a of the body portion 120 and then assembled with the nut, and the coupling formed in the second rotary joint portion 130b The bolt member may be inserted through the second joint connection hole 126b of the body 120 and then assembled with a nut.

In addition, the first and second rotational joints 130a and 130b may be coupled through a leaf spring (see FIG. 11 ). Due to this, the first and second rotational joints 130a and 130b may move independently and interact with each other.

That is, the first and second rotation joints 130a and 130b may independently perform rotational movement according to the left and right tilt of the board. In this case, as the first and second rotational joints 130a and 130b are mutually coupled by a leaf spring, the first and second rotational joints 130a and 130b may interact and move.

The first and second rotary joints 130a and 130b interact and move independently according to the left and right inclination of the board, but even if the board is inclined to the left or right by the combined leaf spring, the center of gravity is reduced by the interaction. It is shared so that the wheels do not lift and fall over.

In addition, a stopper formed in the wheel support 140 may be inserted into the through hole formed in the first and second rotating joints 130a and 130b, and then the nut may be assembled.

As a result, the first and second rotational joints 130a and 130b according to an embodiment of the present invention form a first rotational shaft by coupling with the body 120, and a second rotational shaft by coupling with the wheel support 140 Double rotation is possible as the rotating shaft is formed.

In addition, the first and second rotational joints 130a and 130b may have a second rotation axis in the longitudinal direction of the wheel support 140 by coupling with a stopper formed on the wheel support 140.

As a result, the rotation radius of the wheel member may be determined by the movement of the first and second rotational joints 130a and 130b by the first and second rotational axes. Accordingly, the rotation radius of the wheel member may be determined by summing the rotation range by the first rotation axis and the rotation range by the second rotation axis.

In an embodiment of the present invention, a final rotation range obtained by adding a rotation range by the first rotation axis and a rotation range by the second rotation axis may be at most 90 degrees.

The positions of the plurality of stoppers formed on the wheel support 140 may be different. The rotation radius of the first and second rotating joints 130a and 130b may vary according to the position of the stoppers formed on the wheel support 140 (intervals between the plurality of stoppers).

Wheels may be coupled to both ends of the wheel support 140 so as to be rotatable. That is, although not shown in detail in FIGS. 1 to 6, a shaft coupled to rotate the wheel may be included at both ends of the wheel support 140. Even if the wheel rotates, the wheel support 140 itself may not rotate.

In summary, a plurality of stoppers may be formed on the wheel support 140. At this time, the stopper is inserted into the through holes respectively formed in the first and second rotary joints 130a and 130b to couple the wheel support 140 and the first and second rotary joints 130a and 130b, and at the same time, a plurality of stops are formed. The rotation radius of the first and second rotational joints 130a and 130b may be determined by an angle formed by the stopper and the first and second rotational joints 130a and 130b. Accordingly, by adjusting the length between the plurality of stoppers formed on the wheel support part 140, the rotation radius of the first and second rotating joints 130a and 130b may be adjusted.

Although not clearly shown in FIGS. 1 to 6, the spacing between the plurality of stoppers formed on the wheel support 140 may be different. In addition, depending on the implementation method, the wheel support 140 may further include a gap adjusting member (not shown) for adjusting the gap between the plurality of stoppers.

The rotation radius of the first and second rotation joints 130a and 130b may be determined according to the interval between the plurality of stoppers.

In more detail, the first rotary joint 130a may be coupled to the first stopper of the wheel support 140, and the second rotary joint 130b may be coupled to the second stopper of the wheel support 140. . At this time, since the first rotary joint portion 130a and the second rotary joint portion 130b are coupled by the leaf spring, the first rotary joint portion 130a and the second rotary joint portion 130b interact and move, and the first The sum of the angle between the rotation joint portion 130a and the first stopper and the angle between the second rotation joint portion 130b and the second stopper may always move in proportion to be constant.

However, as described above, when the first and second rotational joints 130a and 130b move in the inward direction, the rotational movement of the body 120 may be limited. That is, when the first and second rotational joints 130a and 130b move in the inward direction, they are abutted by the body 120 and thus the movement in the inward direction may be restricted.
