The present invention relates to a board having a multi-directional caster capable of spontaneous forwarding by rolling, and more particularly, voluntary forwarding by rolling, which allows the multi-directional caster to voluntarily move forward in a corrugated line by the rolling motion of the board. It relates to a board with possible multidirectional casters.

Conventional skateboards support the driver's one foot on a board with wheels, and then push the other foot off the ground in the direction of propulsion to give propulsion and raise both feet on the top of the board while accelerating the front and rear feet. By alternately intersecting the position points in the opposite direction, the skateboard can be moved in the corrugated copper line.

On the skateboard, the driver rolled the ground by himself to generate artificial propulsion to move forward, but this limited the forward power of the skateboard, which reduced interest in the movement, and the ability to steer independently due to the impossibility of independent steering rotation of the caster. There was a problem that caused a safety accident.

In recent years, to compensate for this problem, a board has been proposed in which a driver may repeatedly advance the board without generating a ground and generate a forward force.

The board of the prior art as shown in the Republic of Korea Patent Application No. 2003-25663, in the skateboard comprising a connecting element for fixing the front board 10 and the rear board 20 in a spaced apart state, the two boards At least one of (10, 20) includes at least one directional caster (13, 23) attached to the bottom of the plate (11, 21), wherein the connecting element is made of an elastic body to allow torsional or bending elastic restoration.

In this skateboard, when the driver tilts the foot on the front board 10 to the right in the direction of travel, the roller arm 35 of the directional caster 13 of the front board 10 returns to the left in the opposite direction and rolls. 36 rotates to the right to make the right turn.

On the contrary, when the driver tilts the foot on the rear board 20 to the right in the direction of travel, the roller arm 25 of the directional caster 23 of the rear board 20 returns to the left in the opposite direction and the roller 26 moves to the right. Rolled toward the rear board 20 is rotated to the left as a result of the right turn.

On the basis of the two cases, the front board 10 is tilted to the right in the direction of travel and the rear board 20 is tilted to the left to make the right turn of the small radius as a whole to move forward.

However, the skateboard according to the prior art according to the front board 10 and the rear board 20 by mounting the casters 13 and 23 in a single number, respectively, through the connecting element 10 and the back board ( 20) can generate a torsional force, but it is difficult to balance the board, difficult to ride the case board, there is a problem that can easily drop the interest for beginners because it takes a long time skilled.

Moreover, at the time when the board starts or ends, the driving speed is close to “0”, which makes it more difficult to maintain the equilibrium and balance of the board, which may cause a driver's safety accident.

In addition, when a single caster (13, 23) is mounted on the front board 10 and a pair of casters correspondingly mounted on the rear board 20, the safety of the board can be guaranteed, but a pair mounted independently Due to the support of the casters (13,23) of the back board 20 can not generate a twist there was a problem that can not generate the forward force of the board.

Particularly, when the board is inclined by giving twist to the rear board 20 while the board is being driven, the opposite caster of the caster, which bears the load of the pair of casters, floats on the ground.

That is, when the driver tilts the boards 10 and 20 in one direction for advancing the boards 10 and 20, the center of gravity of the casters 13 independently installed on the lower parts of the boards 10 and 20 is rotatably installed. As the caster 13 in the opposite direction floats off the ground while focusing only on the caster 13 in one direction, the board 10 and 20 loses the balance and balance, so that the boards 10 and 20 easily roll over. There was a problem causing a driver's safety accident.

In order to prevent the board overturning like this, the driver had to drive with a large turning radius of the skateboard, so that the speed and the instantaneous steering ability of the skateboard fell.

In particular, the elastic body 65 of the board is not a means for generating a forward force directly on the board (10, 20) itself, but indirect help to elastically achieve the rolling of the back board 20 of the front board (10) It is to be given only, because the forward force of the board (10, 20) because it is not a means for generating a direct propulsion has had a weak forward force of the board.

In addition, the Republic of Korea Utility Model Registration No. 20-0371541 is a skateboard comprising a connecting member for rotating the separated front and back boards in a spaced apart state, the two boards on which the user's feet are placed, and is mounted on the bottom of the board Being fixed to the fixed wheel and the lower surface of the board is coupled to the penetrated fixture having an insertion hole in the center of the lower surface, accommodated inside the pivoted height and inserted into the insertion hole to rotate perpendicular to the plane of the board A pivot pin, a frame member placed on a lower surface of the pivoted fixture to hold both boards horizontally and fixedly coupled to the pivot pin, and a board which is caught by the frame member during pivoting of both boards so that the rotation angle is limited. It includes a connection member consisting of a support pin is coupled to the lower surface of the pivot pin vertically with respect to the connection member It is configured to provide a movement of the wheel corresponding to the movement of the board by enabling pivotal rotation about.

However, when moving a pair of boards freely rotated by pivot fixtures and pivot pins on both sides of a pivot frame, rolling a pair of boards is not a way to advance, but a pair of boards meanders (운동 行 運動) This results in waveform advancement.

At this time, the board is difficult to maintain the equilibrium and balance of the board, as it is possible to generate the forward force through the direct meandering movement of the pair of boards, difficult to operate the case board, and long hours of skilled time There was a problem that can easily drop interest for beginners by taking advantage.

In addition, the Republic of Korea Patent Application No. 10-2002-74891 is a fastening plate 10 and the support shaft 20 is fixed to the fastening plate 10, the support shaft 20 is fixed to both ends of the board wheel In the skateboard truck comprising a wheel shaft 30 to which the 31 is attached, the caster 40 is installed on the skateboard truck, but the caster 40 is rotatably coupled to the support shaft 20. It is composed of a rotary ring 41, a bracket 42 extending to one side from the rotary ring 41, and a caster wheel 43 axially coupled to the end of the bracket 42.

However, by the caster 40 rotatably coupled to the fastening plate 10 and the brake unit 50 is installed, the traction between the skateboard truck and the ground can be increased, thereby increasing the sense of tension for driving, but the skateboard In order to improve the speed of the caster 40 is provided with a forward force improving means for improving the speed only by manually interlocking according to the steering direction of the skateboard, and additionally equipped with a caster on a normal skateboard As a result, by increasing the ground area with the ground there was a problem that rather reduces the forward force of the skateboard.

This causes a problem of causing a safety accident because it is difficult to sharply turn the roller board without stopping the speed when an urgent situation occurs while driving the roller board.

In addition, the roller board is a rolling operation and a pair of horizontal springs (260a, 260b) through a pair of arms (320a, 320b) and torsion springs (220a, 222a) rotatable to the lower surface of the front board and the rear board The roller board is advanced by bending in the left and right directions, but it is difficult to perform the rolling and bending operations at the same time with two feet on each board. The problem was difficult to learn.

Referring to the operation of the present invention as follows.

Application of the multi-directional caster capable of spontaneous advancement by rolling of the present invention can be applied to various industrial applications, the working embodiment described here is applied to the board for the skateboard shown in Figures 6a to 8b The working relationship will be explained by applying.

First, as shown in Figure 6a, by applying the multi-directional caster capable of spontaneous advance by the rolling of the present invention to look at the operation state as follows.

The forward caster 200 is installed on the lower surface of the board 10 and the heavy material is seated on the board 10. Then, the board 10 is rolled artificially to the (R) side to incline the board to the (R) side. When the center of gravity is loaded on the caster 235 in the (L) direction of the caster means 230 with respect to the main steering shaft 213, the stop key is engaged with the ratchet gear 234a of the one-way rotating means 234. By the 234b, the (R) direction caster 235 becomes the support point in the forward state of the board 10 without being pushed backward, and the caster 235 in the (L) direction is the board, as shown in FIG. While rotating in close contact with the ground at a constant steering angle by the steering means 210 inclined to the support 11 of (10) while the component force F2 (F2 cos.ß) occurs in the diagonal direction at the first position. The board 10 is advanced in the F2 direction.

At the same time, the forwarding caster 200 or the caster means 230 mounted at the front of the board 10 also advances the board 10 in the direction F1 while the component force F1 (F1 cos.α) occurs in an oblique direction.

Subsequently, when the load or force deflected in the (R) direction is distributed and matched on the center line of the board 10 to restore the balance of the board, the board 10 continues to move forward in a constant linear motion by the existing acceleration. do.

Continuously deflecting the center of weight or force to the caster 235 in the direction (L) again with the board 10 inclined to the (L) axis while the main steering axis 213 is centered about the (L). The caster 235 in the direction is a support point in the forward state by preventing the rotation in the rear direction by the one-way rotating means 234, the caster 235 in the (R) direction is inclined at an angle to the combined steering means ( By the angle of 210, the caster 235 in the (L) direction advances the board 10 while maintaining the ecology in close contact with the ground.

In this way, the center of gravity or the force displacement in the (R) or (L) direction rapidly proceeds so that the movement direction of the board 10 proceeds to the corrugated copper wire having a short pitch by the fast rolling of the board 10. do.

In addition, when the caster means 230 is rotated forwardly and intermittently with respect to the steering means 210 as described above, the rear of the steering member 211 when the caster 235 located at the rear rotates forward.

Referring to the operation of the present invention as follows.

First, as shown in Figure 23, the operating state of the board with a multi-directional caster capable of spontaneous advancement by the rolling of the present invention is as follows.

After boarding on top of the board 100, the rolling of the front board 100a is artificially inclined in the (L) side, and the rolling of the rear board 100b is inclined in the (R) side.

As described above, when the front board is inclined toward the (L) side, the caster means 310 in the (L) direction becomes the support point around the main steering shaft 330, and the caster means 310 in the (R) direction moves forward. Turn and move forward.

At the same time, when the rear board 100b is inclined toward the (R) side, the caster means 310 in the (R) direction becomes the support point with respect to the main steering shaft 330 and pivots toward the caster means dd in the (L) direction. Move forward.

As such, the caster means 310 of either the caster means 310 on each of the (R) or (L) sides is rolled forward by the mutually staggered rolling of the boards 100a and 100b to advance in an inclined direction. .

The reason for this is that, as shown in FIG. 24, the component F1 (at the initial position while rotating in close contact with the ground at a constant steering angle by the steering means 300a coupled to the inclined portion 104 of the board 100). F1 cos.α) and F2 (F2 cos.ß) are generated in an oblique direction to advance the boards 100a and 100b in the F1 and F2 directions.

Subsequently, when the force applied to the front board 100a and the rear board 100b is alternately applied to each other, the torsional force applied to the elastic member 320 is released, and the spontaneous forward part (reduced by the restoring force of the elastic member 320) is released. 300 is returned to the center line of the board 100, which is the initial position, to restore the sense of balance of the board 100, and it is possible to advance the board 100 forward by constant velocity linear motion by the existing acceleration.

Then, rolling is artificially applied to the front board 100a in the (R) side direction and rolling of the rear board 100b is performed in the (L) side direction.

As described above, the front board (100a) is inclined toward the (R) side, the caster means 310 in the (R) direction around the main steering shaft 330 becomes a support point, the caster means 310 in the (L) direction Turn forward and move forward.

As such, when the front board 100a and the rear board 100b are repeatedly repeatedly rapidly progressed through the displacement of the center of gravity or the force in the (R) or (L) direction, the board 100 is quickly and rapidly rolling toward the forward direction. As this becomes possible, the pitch moves on a shorter corrugated copper line.

In this way, the caster means 310 mounted to the front and back of the board 100 by the torsionally elastic force of the spontaneous forward portion 300 can be gradually and spontaneously advanced to improve the forward speed even with a small rolling force.

As such, the principle of the forward force is that when the board 100 is rolled in one direction, the steering means 40 is inclined in one direction and the board 100 of the caster means 30 in the (R) or (L) direction is inclined. This is possible because the caster means 310 in the inclined direction becomes the support point and the opposite caster means 310 pivots forward.

Furthermore, by installing the spontaneous forward portion 300 capable of spontaneous advance as described above on the front board 100a and the rear board 100b, respectively, the forward force can be doubled.

As described above, a board having a multi-directional caster capable of spontaneous advancement by rolling of the present invention does not require artificial propulsion by applying rolling to the board through the movement of the center of gravity or the dispersion of force on the board on which the load is placed.

By maintaining it, it is possible to reduce the occurrence of safety accidents and to make it easier for beginners to be interested and operate safely.

Furthermore, the board having a multi-directional caster capable of spontaneous advancement by rolling of the present invention imparts elastic force to the forwarding casters, which cross each other forwardly from the ground by rolling the board so that the caster spontaneously moves forward, thereby spontaneously moving the board. In addition to improving mobility, it is effective to improve forward speed.

In addition, the board having a multi-directional caster capable of spontaneous advancement by rolling of the present invention is spontaneous forward by preventing the caster, which is the support point of the center of gravity, from being pushed backward or idling when rotating in a forward direction with respect to the steering means. It is effective to prevent the loss of force to maximize the forward force of the board.
