Although described in detail below, the propulsion force is generated as the top plate 150 is tilted in the front and rear directions, and has steering ability as the top plate 150 is tilted in the left and right directions.

In the upper and lower plates 150 and 110 coupled to the ball joint 101, two first coil springs 161 which are elastic bodies are disposed between the front end of the upper plate 150 and the front end of the lower plate 110. Both ends of the first coil spring 161 are welded to the upper plate 150 and the lower plate 110, respectively.

The bracket 120 is pivotally coupled to the front end of the lower plate 110 by the thrust bearing 127, and the front wheel 121 is rotatably mounted 360 degrees to the bracket 120. The bracket 120 is coupled to the front end of the lower plate 110 in a bent downward state. Such a structure of the bracket 120 is to position the lower plate 110 close to the ground, to lower the center of gravity to have a stable structure, and at the same time to prevent the front wheel 121 is caught and rolled over when passing through the unevenness. will be. In addition, a first stopper 123 extending upward through the upper plate 150 is fixed to the bracket 120. As shown in FIG. 2, the first stopper 123 includes a pillar 123p fixedly welded to the lower plate 110 and a head 123h welded and fixed to an upper end of the pillar 123p. The pillar 123p of the first stopper 123 penetrates through the hole formed in the tip of the upper plate 150. The first stopper 123 configured as described above is configured to prevent the top plate 150 from inclining too much rearward. When the tip plate 150 is inclined too much, the tip of the top plate 150 interferes with the head 123h of the first stopper 123. To prevent inclination. As described above, in order to incline the top plate 150 in the front-rear direction or the left-right direction, the diameter of the hole is larger than the diameter of the pillar 123p, so that the separation must occur, and the top plate 150 is inclined by the separation. Can lose.

In addition, in the middle of the length of the lower plate 110, two supports 130 are respectively coupled by the thrust bearing 137 to extend to the rear of the support 130, the two supports 130 are the length of the lower plate 110 Each of the thrust bearings 137 is welded to the thrust bearing 137 so as to be able to pivot in the horizontal direction based on the extension line. The support 130 is pivoted about the front end coupled to the thrust bearing 137, the rear wheel 131 is mounted to the rear end of the support 130. More specifically, the cover 139 surrounds one end of two supports 130 coupled to the thrust bearing 137 in the middle of the length of the lower plate 110. Thrust bearings 137 are positioned inside the cover 139, respectively, and one end of the support 130 having a ball shape is inserted between the thrust bearings 137. Therefore, the support 130 is free to pivot in the left and right directions between the thrust bearings (137).

On the other hand, the two lugs 119 and the rear wheels 131 formed on the bottom end of the lower plate 110 is connected to the second coil spring 162, both ends of the second coil spring 162 in the form of a hook, One end of the coil spring 162 is fitted into the through hole of the lug 119 and the other end of the second coil spring 162 is fitted into the bracket 132 supporting the rear wheel 131. The second coil spring 162 is tensioned when the support 130 pivots in the lateral direction of the lower plate 110, and in the tensioned state of the second coil spring 162, the support 130 is rearward of the lower plate 110. It provides elastic force to face.

In addition, the second stopper 125 is fixed to the lower plate 110 to the outside of the two support 130 to prevent the support 130 from being opened too much.

4A and 4B, a ring-shaped bracket 141 surrounds the support 130 in the middle of the length of each support 130. One end of the link 140 is connected to the bracket 141, and the two links 140 connected to the respective support units 130 are inclined in the mutually gathering direction, and the other end of the link 140 is the upper plate 150. It is hinged to the frame 151 fixed to the bottom.

The following describes the operation relationship of the tri skateboard configured as described above.

As shown in (a) of FIG. 5, in the state where the user does not climb on the top plate 150, the top plate 150 is positioned in a horizontal state as shown in FIG. 2. The horizontal state is maintained by the elastic force of the first coil spring 161 and the second coil spring 162.

In this state, the user raises one foot each at the front end and the rear end of the upper plate 150 and is positioned to look forward.

In this state, the user shifts the weight to the rear so that the upper plate 150 is inclined backward (FIG. 5B) or the weight is moved forward so that the upper plate 150 is tilted forward (FIG. 5C). ).

The following describes the operation of the Tri Skateboard according to the weight transfer.

As shown in (b) of FIG. 5, when the user moves the weight backward, the top plate 150 is inclined backward and the tip of the top plate 150 is lifted up. As such, when the front end of the upper plate 150 is raised, the first coil spring 161 is extended, and the rear end of the upper plate 150 is lowered and the slope of the link 140 is reduced while being pushed in the direction away from each other. . In this way, the force to push the two support 130 in the mutually outward direction to generate the driving force by rotating the three wheels (121, 131).

In this state, the first coil spring 161 generates a force to contract, and the second coil spring 162 provides an elastic force so that the support 130 is positioned in an original state, that is, parallel to each other. This elastic force acts to position the top plate 150 in a horizontal state. Therefore, if the user removes the force after moving the weight backward, the upper plate 150 is horizontal by the elastic force of the first and second coil springs (161, 162).

In this state, when the user moves the weight in the opposite direction, that is, forward, the first coil spring 161 contracts, and the links 140 rotate in the direction in which the support 130 is close to each other while the inclination increases. The force trying to move in the direction where 131 gathers is converted into thrust.

Therefore, the tri-skateboard 100 will generate a driving force in the same direction even if the user moves the weight forward or rearward.
In the tri skateboard configured as described above, the first coil spring 161 and the second coil spring 162 merely provide an elastic force to keep the top plate 150 in a horizontal state, and the horizontal of the top plate 150 is a user. The first coil spring 161 and the second coil spring 162 are additional components added to the tri skateboard 100 because they can be caught by the sense of balance.

And when the user tilts to the left and right direction for steering of the skateboard 100, the center of gravity is changed to the left and right direction, the front wheel 121 is turned with the bracket 120 to have steering. Therefore, the user generates propulsion while tilting the body in the front-back direction while standing on the top plate 150 of the tri-skateboard 100, and adjusts the traveling direction by tilting in the left-right direction.

Second Embodiment

When comparing the second embodiment with the first embodiment, the upper and lower plates are hinged so that the upper plate can be inclined in the front, rear, left and right directions instead of the ball joint of the first embodiment, and the upper end of the upper plate is divided and then divided. By connecting the part with the torsion bar, the tip of the top plate is configured to roll based on the torsion bar. In this configuration, the top plate is inclined in the front-rear direction around the hinge, and the top plate tip is inclined in the left-right direction about the torsion bar, but the components are configured to have propulsion force and steering, and the other components are the same. Therefore, below, only the other components will be described in detail, and detailed descriptions of the same components will be omitted.

6 is a front view showing a tri skateboard according to a second embodiment of the present invention.

As shown in FIG. 6, the tip of the top plate 150 is divided into two. Hereinafter, for convenience, it is referred to as the 'tip portion 150F' and the 'rear portion 150B'.

And the torsion bar 117 is connected to the front end portion 150F and the rear end portion 150B divided into two. As the torsion bar 117 connects the front end portion 150F and the rear end 150B of the upper plate 150 as described above, the rear end portion 150B is inclined in the left-right direction, that is, it does not roll, but the front end portion 150F is relatively Rolling is inclined in the horizontal direction by the torsion bar 117. The hinge case 153 is formed on the bottom of the rear end 150B, and the hinge case 111 is formed on the upper surface of the lower plate 110 to mate with the hinge case 153 of the rear end 150B. The hinge shaft 115 penetrates the two hinge cases 111 and 153 so that the rear end portion 150B is inclined in the front-rear direction about the hinge shaft 115. At this time, the tip portion 150F connected to the torsion bar 117 is also inclined in the front and rear direction together with the rear end portion 150B.
As the conditions that can be operated in this way, as described in the first embodiment, the diameter of the hole formed in the tip portion 150F of the upper plate 150 is larger than the diameter of the pillar 123p of the first stopper 123, The top end portion 150F is inclined in the left and right directions due to a difference between the diameter of the pillar 123p and the diameter of the hole, that is, the spaced apart, and at the same time, the first stopper 123 is interlocked with the front end inclination of the rear end portion 150B. Move up and down along the pillar 123p).

On the other hand, the first stopper 123 extending upward from the bracket 120 of the front wheel 121 is located through the front end portion 150F, and the user puts one foot on the front end portion 150F and the rear end 150B. Press the front end portion 150F in a left and right direction in a state of being placed thereon, and move the weight to the front end portion 150F or the rear end portion 150B of the upper plate 150 to generate a driving force.
The front wheel 121 and the rear wheel 131 is a directional caster, the propulsion force is the rear board leans backwards and the two rear wheels 131 open, as in the tri-board (Fig. 1b) described in the prior art, the opposite When the top plate 150 is inclined in the forward direction, two rear wheels 131 are collected to generate a driving force forward. In the case of the first embodiment, steering is performed by tilting the top plate 150 in the left and right directions, and in the second embodiment, the front wheel 121 is tilted by the front end portion 150F of the top plate 150 in the left and right directions. The mounted bracket 120 pivots about the thrust bearing 127 to have directionality.

As described in detail above, the tri-skateboard of the present invention is to generate a propulsion force by moving the weight in the front and rear direction on the top plate, it is possible to move without a handle bar and a front pillar that the user can catch. Therefore, the size is small, convenient to carry and carry, it is possible to improve the sense of balance than the conventional tri-board.

In addition, the propulsion force is generated while spreading or pinching the legs as in the conventional tri-board, but the tri-skateboard of the present invention uses different leg muscles because the weight is moved in the front-back direction. So you can develop triboards and other muscles.

Although the technical idea of the tri-skateboard of the present invention has been described above with the accompanying drawings, this is illustrative of the best embodiment of the present invention and is not intended to limit the present invention.
