Description

어린이용 4륜차{FOUR-WHEEL VEHICLE FOR CHILDREN}Four-wheeled vehicle for children {FOUR-WHEEL VEHICLE FOR CHILDREN}

본 고안은 어린이용 4륜차에 관한 것으로서 이를 보다 구체적으로 설명하자면 크랭크아암을 교대작동시킴으로서 구동되는 구동륜을 차체 중앙에 장치하여 차체를 자전거 구동방식으로 전·후진시킬수 있도록 함과 동시에 핸들을 조작하면 전륜과 구동륜이 같은 각도로 조향되도록 하므로서 보다 안전하고 유희적이면서 어린들의 신체도 단련시킬수 있는 4륜차를 얻을수 있도록 한 것이다.The present invention relates to a children's four-wheeled vehicle, which will be described in more detail. A drive wheel driven by alternating crank arms is installed at the center of the vehicle body so that the vehicle body can be moved forward and backward in a bicycle driving manner and the front wheel is operated when the steering wheel is operated. By allowing the steering wheel and steering wheel to be steered at the same angle, a four-wheeled vehicle can be obtained that is safer, more playful, and can also train young children.

일반적인 어린이용 4륜차는 차체에 어린이가 탑승한 후 발을 지면에 굴려야만 이동이 가능토록 하였기 때문에 이동이 원할하지 못할 뿐만 아니라 이동에 상당한 힘이 요구되어 어린이들이 큰 재미를 느끼지 못하는 문제점이 있었고 또한 발을 지면에 구를 때 다리와 장애물의 접촉이 쉽게 이루어져 안전사고의 위험도 있었다.In general, children's four-wheeled vehicles can not move because they can move only when they have to roll their feet on the ground after moving on to the body, and they have a problem that they do not have great fun because they require considerable force. There was also a risk of a safety accident when the feet were rolled to the ground, because the legs and obstacles were easily contacted.

이를 해결하기 위해 전륜을 크랭크형식으로 구동시킬수 있도록 하면서 크랭크 발판을 차체 내부에 장치하여 어린이의 다리가 차체 외부로 노출되지 않도록 한 4륜차가 개발되었으나 이 또한 이동이 원할하지 못한 문제점이 있었다.In order to solve this problem, a four-wheeled vehicle was developed in which a crank footrest was installed inside the vehicle body so that the children's legs were not exposed to the outside of the vehicle body while driving the front wheels in a crank-type.

본 고안은 위와같이 종래의 어린이용 4륜차에서 나타나는 문제점들을 해결하기 위해 구동륜을 별도로 장치하여 차체를 5륜으로 구성하고 구동륜 양측에는 페달을 가진 크랭크아암을 장치하여 차체를 자전거 이동방식으로 이동할수 있도록 한것인데 이를 첨부된 도면과 함께 더욱 상세히 설명하면 다음과 같다.In order to solve the problems presented in the conventional children's four-wheeled vehicle as described above, the driving wheels are separately provided to configure the vehicle body by five wheels, and the crank arms with pedals are provided on both sides of the driving wheels so that the vehicle body can be moved by a bicycle movement method. It will be described in more detail with the accompanying drawings as follows.

차체(1)에 이동바퀴를 4륜으로 구성하고 전륜(2)에는 핸들(10)의 조작에 따라 작동하는 링크형의 조향장치(11)를 구비하는 것에 있어서, 차체(1) 중앙부에 구동륜(5)이 회전가능케 장치된 지지대(6)를 마련하여 그 상부를 핸들축(10)의 끝단부와 연결하고 지지대(6) 일측으로는 연결작동봉(8)을 형성하여 전륜(2)의 링크형 조향장치(11)와 작동판(9)으로 연결하되, 연결작동봉(8)의 연결부(801)를 작동판(9) 일측의 장공(901)에 접속되도록 하고 작동판(9) 중앙부는 차체(1)에 고정되는 고정축(902)에 회동 가능케 고정 되도록 하며 지지대(6) 양측으로는 페달(701)을 가진 크랭크아암(7)(7')을 마련하여 그 끝단을 지지대(6)를 관통시키면서 지지대(6) 사이의 구동륜(5) 양측 중심부에 고정하여서된 것이다.In the case where the wheel 1 comprises four wheels and the front wheel 2 has a link-type steering device 11 that operates according to the operation of the handle 10, the driving wheel ( 5) is provided with a support (6) rotatably connected to the upper end of the handle shaft (10) and the connecting rod of the front wheel (2) by forming a connecting operating rod (8) on one side of the support (6) It is connected to the type steering device 11 and the operating plate (9), so that the connecting portion 801 of the connecting operating rod (8) is connected to the long hole (901) on one side of the operating plate (9) and the central portion of the operating plate (9) Crank arms (7) (7 ') having a pedal (701) on both sides of the support (6) to be rotatably fixed to the fixed shaft (902) fixed to the vehicle body (1) to the end of the support (6) While penetrating through the driving wheel 5 between the support 6 is fixed to the center of both sides.

이와같이된 본 고안은 구동륜(5) 양측의 페달(701)에 발을 올려 놓은 다음 크랭크아암(7)(7')을 교대작동시키면 차체(1) 이동이 가능케되며,In this way, the present invention puts the foot on the pedals 701 on both sides of the driving wheel 5, and then alternately actuates the crank arms (7) (7 '), the vehicle body (1) can be moved,

그리고 구동륜(5)의 지지대(6)에 연결고정된 핸들축(10)을 핸들(10)에 의거하여 좌·우 어느 방향으로든 회전시키면 지지대(6)가 핸들축(10)과 동시에 회동하게 되고 이와동시에 지지대(6)에 회전가능케 설치된 구동륜(5)도 지지대(6)가 회동하므로서 첨부도면 도 3에서와 같이 가변되어 진행 방향이 전환되게 된다.Then, when the handle shaft 10 fixed to the support 6 of the driving wheel 5 is rotated in either of the left and right directions based on the handle 10, the support 6 rotates simultaneously with the handle shaft 10. At the same time, the driving wheel 5 rotatably installed on the support 6 is also variable as shown in FIG. 3 as the support 6 is rotated so that the traveling direction is changed.

이렇게 지지대(6)가 회동하게 되면 지지대(6) 일측의 연결작동봉(8)도 같이 회전하면서 작동판(9)을 첨부도면 도 3에서와 같이 고정축(902)을 중심으로 하여 상대방향으로 회동시키게 되고 이때 회전하는 연결작동봉(8)의 연결부(801)는 작동판(9) 일측의 장공(901)을 따라 이동하게 된다.When the support 6 is rotated in this way, the connecting operation rod 8 on one side of the support 6 rotates together, and the operating plate 9 is attached to the relative direction about the fixed shaft 902 as shown in FIG. 3. In this case, the connecting portion 801 of the connecting operating rod 8 that rotates moves along the long hole 901 on one side of the operating plate 9.

상기와 같이 작동판(9)과 연결작동봉(8)이 서로 상대방향으로 회전하게 되면 작동판(9)의 외측 양단에 연결된 링크(111)가 가변되면서 전륜(2)의 조향판(3)을 회전축(301)에 의거하여 회동시킴과 동시에 전륜(2)도 회동되어 진행방향이 전환되게 된다.As described above, when the operating plate 9 and the connecting operating rod 8 rotate relative to each other, the link 111 connected to both ends of the outer side of the operating plate 9 is variable and the steering plate 3 of the front wheel 2 is changed. Rotate on the basis of the rotary shaft 301 and at the same time the front wheel (2) is also rotated to change the traveling direction.

따라서 본 고안은 상기한 바와같이 차체(1) 중앙에 별도의 구동륜(5)이 구성되기 때문에 차체(1)의 이동이 안전하게 됨은 물론 승차감도 향상되는 이점이 있으며 또한 구동륜(5)의 회전이 크랭크아암(7)(7')을 교대 작동 즉, 자전거 이동방식과 동일한 방법으로 실시 되므로 이동이 용이 하면서 보다 빠르고 원할하게 되는 효과가 있을 뿐만 아니라 즐기면서 신체도 단련시킬수 있는 효과도 있게되며 그리고 구동륜(5)이 핸들(10)과 동시 작동하고 전륜(2)은 구동륜(5)의 지지대(6)에 고정되어 있는 연결작동봉(8)과 작동판(9) 및 조향장치(11)의 연동에 의해 구동륜(5)과 동시에 같은 각도로 방향전환이 가능하기 때문에 이동중에도 방향전환을 안전하고 원할하게 할수 있는 이점이 있게되는 것이다.Therefore, the present invention has the advantage that the vehicle body 1 is secured as well as the ride comfort is improved because the separate drive wheel 5 is configured in the center of the vehicle body 1 as described above, and the rotation of the drive wheel 5 is cranked The arm (7) (7 ') is carried out in the same way as the shift operation, that is, the bicycle movement method, so that it is easy to move, faster and smoother, and also has the effect of strengthening the body while having fun and driving wheels ( 5) Simultaneously operates with the handle 10 and the front wheel 2 is connected to the operation of the connecting operating rod 8, the operating plate 9 and the steering apparatus 11, which are fixed to the support 6 of the drive wheel 5. By changing the direction at the same angle at the same time as the drive wheel (5) is an advantage that can be changed safely and smoothly during the movement.
