The vertical frame 20 may be further provided with a clamp (not shown in the figure) in order to fix the height while the height is adjustable, it can be folded for ease of storage of the kickboard (1). This will be described later.
상기 핸들부(10)는 상기 수직 프레임(20)의 상단에 수평방향으로 중심부가 고정되며, 좌, 우측에 사용자의 손을 파지할 수 있도록 손잡이가 구비된다.The handle portion 10 has a central portion fixed in the horizontal direction to the top of the vertical frame 20, the handle is provided to hold the user's hands on the left and right.

As shown in (b) of FIG. 2, the directional caster 70b is characterized in that the rotation axis direction S is inclined by a predetermined angle θ from a vertical line. To this end, it can be seen that the bracket and the scaffold are connected to have a constant angle, unlike in (a).

Next, when both feet are alternately pushed to the left and right on the basis of the vertical frame 20, the directional caster 70b is alternately changed to the right and left around the rotation axis. The repetition of these movements generates self-propulsion and moves forward without moving the ground. Self-propelled mechanism using the directional caster (70b) is disclosed in detail in Republic of Korea Patent No. 10-394848, refer to this.
한편, 이와 다른 방법으로도 자체 추진력을 얻을 수 있는 바, 이는 도 3 및 도 4를 참조하여 설명한다. On the other hand, it is also possible to obtain the self-propulsion by other methods, which will be described with reference to FIGS. 3 and 4.
도 3에 도시된 바와 같이, 핸들(10)은 좌측으로 틸팅하게 되면, 지면에 근접하게 되고, 이 때 수평프레임(50)이 비틀리게 된다. 이 때 후방바퀴(70)의 롤러는 회전축을 중심으로 우측으로 회전된다. As shown in FIG. 3, when the handle 10 is tilted to the left side, the handle 10 is close to the ground, and the horizontal frame 50 is twisted. At this time, the roller of the rear wheel 70 is rotated to the right around the rotation axis.
이 상태에서 틸팅을 하는 외력을 제거하면 탄성복원력에 의해 수평프레임(50)의 비틀림이 풀리게 된다. If the external force to tilt in this state is removed, the torsion of the horizontal frame 50 is released by the elastic restoring force.
다음으로, 도 4에 도시된 바와 같이, 핸들(10)을 우측으로 틸팅하게 되면, 지면에 근접하게 되고, 이 때 수평프레임(50)이 아까와는 반대방향으로 비틀리게 된다. 이 때 후방바퀴(70)의 롤러는 회전축을 중심으로 좌측으로 회전된다. Next, as shown in FIG. 4, when the handle 10 is tilted to the right, the handle 10 is brought close to the ground, and the horizontal frame 50 is twisted in the opposite direction. At this time, the roller of the rear wheel 70 is rotated to the left side about the rotation axis.
이와 같이 방향성 캐스터(70a)가 우측, 좌측으로 번갈아가며 회전되면서 방향성 캐스터의 특성에 의해 자체 추진력이 발생되어 킥보드가 전진하게 되는 것이다. As such, the directional caster 70a rotates alternately to the right and the left, so that self-propulsion is generated by the characteristics of the directional caster, so that the kickboard is advanced.
이와 같이 비틀림부를 구비함으로써 수평 프레임이 비틀림과 원상태로 복원이 가능한 구조를 갖는 본 발명에 의한 킥보드는 자체 추진력을 얻는데에도 작용을 하지만, 한편으로는 회전시 원심력을 제어하는 기능도 할 수 있다. The kickboard according to the present invention having a structure in which the horizontal frame is capable of restoring the torsion and the original state by providing the torsional portion as described above also acts to obtain self-propulsion, but also has the function of controlling the centrifugal force during rotation.
보다 구체적으로 설명하면, 킥보드가 어느 정도의 속력을 갖고 진행하는 중 급격한 커브로 회전을 하는 경우, 원심력에 의해 넘어지기 쉽다. In more detail, when the kickboard rotates at an abrupt curve while moving at a certain speed, it is likely to fall down due to the centrifugal force.
그러나 본 실시예에 의하면 도 3 및 도 4와 같이 급격한 커브로 회전시 몸을 회전하고자 하는 방향으로 눕힐 수 있어 원심력을 제어함으로써 안정적인 주행을 유지할 수 있다. However, according to the present embodiment, when the body rotates in a sharp curve as shown in FIGS. 3 and 4, the body can be laid in the direction to be rotated, thereby maintaining a stable running by controlling the centrifugal force.
또는 킥보드는 전방바퀴(30)가 수직 프레임(20)을 통해 핸들(10)에 의해 직접적으로 조작되기 때문에 핸들(10)의 움직임에 매우 민감한 반응을 하게 된다. 만약 고속으로 주행하는 중 사용자가 실수가 핸들(10)을 과도하게 움직이는 경우 넘어져서 큰 부상으로 이어질 수 있다. Or the kickboard is very sensitive to the movement of the handle 10 because the front wheel 30 is directly manipulated by the handle 10 through the vertical frame 20. If the user accidentally moves the handle 10 excessively while driving at high speed, it may fall and lead to a large injury.
그러나 본 실시예에서는 핸들(10)에 의해 직접적으로 전방바퀴(30)를 조작하는 대신, 조향부(40)를 틸팅함으로써 매우 안정적으로 조향할 수 있는 것이다. However, in the present embodiment, instead of operating the front wheel 30 directly by the handle 10, by steering the steering unit 40 can be very stable steering.
이와 같이 수평프레임(50)이 비틀림 및 탄성복원이 가능한 구조로 형성함으로써, 자체추진력을 얻을 수 있고, 회전시 원심력을 제어할 수 있으며, 또한 전방바퀴(30)의 직접적인 조작 대신 조향부(40)의 틸팅으로 안정적인 조향 및 회전을 할 수 있는 것이다. As such, the horizontal frame 50 has a structure capable of twisting and restoring elasticity, thereby obtaining self-propelling force, controlling centrifugal force during rotation, and also steering unit 40 instead of direct manipulation of the front wheel 30. By tilting, stable steering and rotation are possible.
도 4 및 도 5를 참조하면, 상기 수직 프레임(20)은 상기 수평 프레임(50)방향으로 절첩가능하다. 4 and 5, the vertical frame 20 may be folded toward the horizontal frame 50.
상기 수직 프레임(20)은 하부 프레임(23)과, 상부 프레임(21)과, 커버(25)로 구성된다.The vertical frame 20 includes a lower frame 23, an upper frame 21, and a cover 25.
상기 하부 프레임(23)은 하부에 상기 전방 바퀴(30)와 연결되고, 상기 상부 프레임(21)은 상기 하부 프레임(23)과 연결된다.The lower frame 23 is connected to the front wheel 30 at the bottom, and the upper frame 21 is connected to the lower frame 23.
여기서 상기 하부 프레임(23)과 상기 상부 프레임(21)은 절첩가능하도록 힌지결합부(27)에 의해 연결되어 있음을 알 수 있다.Here, it can be seen that the lower frame 23 and the upper frame 21 are connected by the hinge coupling portion 27 to be foldable.
상기 커버(25)는 평상시 상기 하부 프레임(23)과 상기 상부 프레임(21)의 일측의 외측을 감싸며 형성되어 상기 상부 프레임(21)의 회동을 제한한다. The cover 25 is usually formed to surround the outer side of one side of the lower frame 23 and the upper frame 21 to limit the rotation of the upper frame 21.
이때 상기 상, 하부 프레임(21, 23)과 상기 커버(25) 사이에 개재되며, 상기 커버(25)가 상기 힌지결합부(27)의 외측에 위치하도록 탄성지지하는 탄성 부재(29)가 더 구비된다.In this case, an elastic member 29 is interposed between the upper and lower frames 21 and 23 and the cover 25, and the elastic member 29 is elastically supported such that the cover 25 is located outside the hinge coupling part 27. It is provided.
여기서, 상기 탄성 부재(29)는 상기 하부 프레임(23)의 상단에 직경을 선단보다 확장시켜 형성하는 턱에 걸리도록 위치되고 그 선단은 상기 걸림턱에 걸리도록 위치된다.Here, the elastic member 29 is positioned to be caught on the upper end of the lower frame 23 to the jaw formed to extend the diameter than the tip and the tip is positioned to be caught by the locking jaw.
이와 같이 구성된 상기 수직 프레임(20)은 킥보드를 사용할 경우에 상기 힌지결합부(27)가 절첩되지 않도록 상기 힌지결합부(27)를 상기 커버(25)가 감싸며 구비된다.The vertical frame 20 configured as described above is provided with the cover 25 surrounding the hinge coupler 27 so that the hinge coupler 27 is not folded when a kickboard is used.
여기서 상기 상, 하부 프레임(21, 23)과 상기 커버(25) 사이에 개재된 상기 탄성 부재(29)는 압축되지 않은 상태로 상기 커버(25)를 지지하고, 지지된 상기 커버(25)로 인해 상기 상부 프레임(21)이 회동되지 않는다.Here, the elastic member 29 interposed between the upper and lower frames 21 and 23 and the cover 25 supports the cover 25 in an uncompressed state, and is supported by the supported cover 25. Therefore, the upper frame 21 is not rotated.
그러나 상기 킥보드(1)를 사용하지 않고 보관할 경우에는, 상기 커버(25)를 상방향으로 밀면 상기 힌지결합부(27)가 노출되고, 이때 상기 상부 프레임(21)을 상기 수평 프레임(50) 방향으로 회동시킴으로써 상기 조향부(40)가 절첩된다.However, when the kickboard 1 is stored without using the cover 25, when the cover 25 is pushed upward, the hinge coupler 27 is exposed, and the upper frame 21 is oriented in the horizontal frame 50. The steering part 40 is folded by rotating.
여기서 상기 탄성 부재(29)는 압축된 상태로 상기 커버(25)가 후퇴하지 않도록 상기 걸림턱(도면에 미도시)에 의해 견고하게 고정된다.Here, the elastic member 29 is firmly fixed by the locking jaw (not shown in the figure) so that the cover 25 does not retreat in a compressed state.
이처럼 절첩된 상기 조향부(40)로 인해 공간 제한 없이 보관이 용이하다.The folded steering portion 40 is thus easy to store without space limitation.
